Abstract

The method involves fitting a support frame-suspending-device at the support frame (20) for suspending another support frame to be mounted. The support frame-suspending-device is supported or carried by the component on a component of the scaffold, particularly on an already mounted support frame (20.1). The other support frame is detachably supported or suspended on the support frame-suspending-device. An independent claim is included for a method for disassembling a scaffold.

Description

The present invention relates to a method for assembling and a method for disassembling a scaffold on wheels, which can also be referred to as a mobile work platform. A scaffold on wheels of this type is usually constructed or constructed from vertical frames that contain at least two uprights and a plurality of steps respectively that connect them to the ascent and / or descent of people and / or to engage and / or place or support scaffolding platforms, diagonal connection elements and / or horizontal connection elements.

Scaffolding on wheels of this type has been known for many years, for example also from document DE 43 06 732 A1. Such scaffolding on wheels are usually constructed starting from two frames, at whose lower stile ends wheels or rollers that can be locked are fixed. Alternatively, the frames can be fixed respectively on a mobile beam, preferably fixing their uprights on or in suitable vertical supports that are fixedly connected, if necessary horizontally movable with the respective mobile beam, being fixed in the area of the transverse ends of each mobile beam at least two wheels or rollers that can be locked. The two lower frames are constructed, considered perpendicularly with respect to their respective rungs, at a distance of frames parallel to each other respectively in a vertical or perpendicular position. Between the frames it is fixed on its steps so that a scaffolding platform can be disengaged, preferably with the help of the so-called interlocking nails. In this respect it can also be a scaffold plank. In this way a first floor or plant of the scaffolding on wheels is obtained. Interlocking nails of this type are known, for example, from DE 35 37 02 152 A1 and DE 38 22 215 A1. These allow a secure fixation of the parts that contain these interlocking nails, such as scaffolding platforms, crossbars or diagonal and / or horizontal bars on other crossbars or bars that have a particularly round cross section. The interlocking nails or the parts provided therewith may be fixed or rotatably fixed with respect to the crossbars or bars therein.

To construct additional floors, additional frames can be fixed or fixed, preferably additional frames can be fitted or fitted on the lower frame, with an additional scaffolding platform being attached between two of these additional frames so that they can be disengaged. Each floor is usually reinforced with the help of two diagonal crossbars that are preferably arranged in the form of a cross. For this purpose they can be fixed so that these diagonals can be disengaged, preferably also with the help of interlocking nails provided at their ends, in two horizontally separated frames at one or the distance from frames, preferably on one of their steps respectively. In this regard, the fixing of the diagonals is carried out at a lateral distance in the uprights or near the uprights of the frames, so that there is enough room for a person who is on a scaffolding platform and with this a further advantageous reinforcement of the scaffolding on wheels.

Not only in the state mounted in a finished way, but also in the construction or disassembly of scaffolding on wheels of this type, the safety of people who are on the scaffolding platforms plays a prominent role. Always ensure that people on scaffolding platforms are safely protected from falling scaffold platforms or scaffolding on wheels. Specifically it is established and required according to the law of equipment and product safety (GPSG) that a product should only be put into circulation, when it is provided, so that in case of proper use or foreseeable misuse, safety is not jeopardized. and the health of users or third parties. In addition, the necessary measures for the safe preparation and use of the means of work must be determined according to the German Operating Safety Ordinance (BetrSichV). In this sense, a safe construction and disassembly of mobile work platforms or scaffolding on wheels must also be guaranteed.

To avoid that a person who is on a scaffold platform in case of construction or disassembly of the scaffold on wheels is not protected against falls, a series of different measures were adopted according to the state of the art.

A first of these measures is known in English with the designation "3T Method" (procedure 3T) or "Through The Trap (Door)" (through the trapdoor). Correspondingly, scaffolding to be assembled or to be disassembled is offered by the English company "Turner Access Ltd." under the name "Octo" and by the English company "SGB Group" under the name "Boss" and by the company Irish “Instant Upright” with the designation “Span”. In this regard the assembly or disassembly of the railing posts is carried out so that the assembler is on a step of a frame arranged below a step scaffolding platform and at the same time with its upper part of the body mounted or disassemble parts that protrude upwards from the frames that support this step scaffolding platform, through the passage opening of the step scaffolding platform that can be closed with a trapdoor that protrudes in this position of the railing posts, at a distance enough above the step scaffolding platform, on the steps of this step scaffolding platform. In case of disassembly of the railing posts, however, there is a problem that the railing posts already at their end separated from the passage opening of the scaffolding platform must be disengaged then, while the assembler is still on the highest level, that is, it is still on the highest-pass scaffolding platform. This procedure leads in any case under the conditions mentioned above to unacceptable safety risks, at least in case of disassembly of the scaffolding on wheels.

An additional measure according to the state of the art is to provide a so-called "advanced" railing. In this regard, the assembler located on the scaffold platform of a lower floor mounts the railing bars of the immediately upper floor to protect a person from falling off the immediately higher scaffolding platform. Scaffolding on wheels are known to be assembled or to be disassembled of this type by the French company "COMABI" with the designations "GENERIS" and "JUNIOR" (document FR 2 908 804 A) and by the German company "Hymer AG ”With the designation“ SC 80 Comfortaufbau ”(document DE 10 2007 011 777 A1).

In the system of the company “COMABI” an advanced double railing is used, with which a hip or back protection railing bar and a knee protection railing bar are integrated in a common railing device. To mount the advanced double railing, initially, from the ground or from the scaffolding platform of a lower floor, an auxiliary lifting bar fixed on the double railing is articulated from a transport position, in which it is held tightly approximately parallel to the railing bar at hip or back height, towards an actuation position, in which the auxiliary lifting bar is at an angle of approximately 70 to 80 degrees with respect to the railing bars down of the double railing. Next, this set of double railing and auxiliary lifting bar is passed through an assembler upwards to a second assembler located on the immediately superior scaffolding platform of the immediately superior floor. This second assembler then hooks this assembly, through a hook attached to the other end of the double railing, on a rung of a frame fixed above the immediately superior scaffold platform in a fixed and rotating manner with respect to the rung or to the frame. Next, the assembler rotates the double railing thus hooked upwards and hooks it through two hooks fixed at the other end, that is, where the auxiliary lifting bar is connected, in a horizontal position on an additional step of an additional frame, which is mounted at a horizontal distance corresponding to the length of the scaffolding platform or the double railing of the first frame. Then the locking of the auxiliary lifting bar on the double railing is disengaged, so that after the incorporation of the immediately superior scaffolding platform, which must be secured with the double railing mounted previously, then the auxiliary lifting bar, when the Mounter is climbing upwards towards the highest mounted scaffolding platform, it can be held tightly again in a position parallel to the highest scaffold bar of the double railing. Alternatively, the aforementioned set of double railing and auxiliary lifting bar can also be initially replaced by the second assembler, after which the double railing can then be mounted with the help of the auxiliary lifting bar, as described above, to carry out an advanced railing on the floor immediately above. The assembly and disassembly of this advanced railing is comparatively expensive and conditioned by the auxiliary lifting bar fixedly connected with each double railing, the assemblers must always handle a correspondingly large weight in case of assembly and disassembly.

The measurement or solution of an advanced railing, as used by the Hymer company, seems to solve this problem. Then there is used as a separate auxiliary lifting bar, in this case in the form of an auxiliary assembly and disassembly bar, with the name "Hymer-Lifter", which is therefore not fixedly connected to the railing bar that will be mounted or that will be disassembled. This auxiliary assembly and disassembly bar has at its drive end a C-shaped hook, laterally open. For the purpose of assembling a scaffolding bar already fixed on a rung of the highest frame by means of an interlocking nail, it can then be hooked, from the floor or the lower floor, in the area of its free end in the Auxiliary bar for mounting and dismounting or suspended on it. This railing bar can then be turned with the aid of the auxiliary mounting and dismounting bar upwards and there it can be fixed on the highest rung of the second highest frame through its additional locking nail provided at the still free end. The disassembly of the railing bar is also carried out with the help of the auxiliary assembly and disassembly bar. For this purpose, the locking nail fixed at one end of the railing bar is initially disengaged, with the aid of a flange placed at the operating end of the auxiliary mounting and dismounting bar, from the rung of the highest frame, after which railing bar can be removed from the step and can be turned down. In the same way, the other interlocking nail of the railing bar of the other frame step can also be disengaged, after which the railing bar can also be removed from this step and can be separated from the scaffolding on wheels. Also with this solution, an additional piece in the form of a long bar is required to assemble and disassemble the railing bars.

According to this, an objective of the invention is to provide a procedure for assembling and a procedure for dismantling a scaffold on wheels or a mobile work platform, by means of which use is achieved greater security in each situation, that is, both in the case of construction or in the case of the assembly of the scaffolding on wheels as in the built state of the scaffolding on wheels, as well as in the case of exploded or in case of disassembly of the scaffolding on wheels, and specifically without necessarily requiring an additional piece for it.

This objective is solved by the features of claim 1 and 6 and by the procedures described below.

In other words, the objective can also be solved by means of a procedure to mount a scaffold on wheels, which is constructed from vertical frames that contain at least two uprights and steps that connect them respectively for the ascent and / or descent of people and / or to engage scaffolding platforms, diagonal and / or horizontal connecting elements, especially crossbars or bars, and which is constructed from at least one lower scaffold platform and from at least one upper scaffold platform, the platform being constructed of upper scaffolding above the lower scaffolding platform, and supporting and / or fixing this scaffolding platform on frame frames, preferably on its steps, and building a frame of the frames, in which a device is fixed or of railing comprising at least two railing elements or in which at least two railing elements are fixed, being arranged placed or arranged the railing elements, considered in the direction of the rungs of the frame, laterally next to each other at a distance from horizontal railing elements, and being fixed or fixing or the railing device rotatably with respect to the frame in this one or being fixed

or by fixing the railing elements in a rotatable manner with respect to the frame therein, and a frame-engaging device being placed or positioned to engage an additional frame to be mounted on the frames, which is supported by an already mounted frame of the frames. frames, especially on at least one of its rungs, preferably on its highest rung and / or that is supported by the frame, and because the additional frame is supported and / or hooked on the frame hitching device so that it can disengaging again and in the supported and / or engaged state there adopts a transitional position and / or starting from the supported and / or engaged state there is directed or transferred to a transitional position, based on which the additional framework can be embedded or it is embedded in the scaffolding on wheels, and because the railing device or the railing elements is fixed or fixed in the additional frame in a rotatable manner with respect to it, and because the frame additionally supported and / or engaged in the frame engagement device in the transition position is disengaged or detached from the frame attachment device and is either raised together with the railing device fixed in the additional frame and also in the other frame in a rotating manner with respect to these frames or together with the railing elements fixed in the additional frame and also in the other frame in a rotating manner with respect to these frames, especially by a person who is on the lower scaffold platform, to a position in which the additional frame is above the transition position or above the transition positions, in which or according to which the additional frame is fixed on or in the frame and, preferably considered in the direction transverse or perpendicular to its rungs, at a distance of horizontal frames, preferably parallel to the other frame, and because the plat Upper scaffold shape is arranged and fixed or supported on the other frame and also on the additional frame, preferably at a distance below the railing device or the railing elements, so that either the railing device, preferably as a back or hip protection element, it serves to protect a person who is on the upper scaffold platform against falls or so that the railing elements, preferably as back or hip protection elements, serve to protect a person who is on the upper scaffold platform against falls.

By means of the aforementioned measures, a scaffolding on wheels can be built according to the principle of an “advanced railing”, guaranteeing at all times of assembly a great safety against falls of people from the scaffolding on wheels that is under construction and also from the scaffolding on wheels constructed.

The invention also relates to a method for dismantling a scaffold on wheels, which is constructed from vertical frames, containing respectively at least two uprights and steps that connect them for the ascent and / or descent of people and / or for hooking scaffolding platforms, diagonal and / or horizontal connecting elements, especially crossbars or bars, and which is constructed from at least one lower scaffolding platform and from at least one upper scaffolding platform disposed above the platform lower scaffolding, which are supported and / or fixed in frame frames, preferably in their rungs, being constructed a frame of the frames and an additional frame of the frames, considered in transverse direction or perpendicular to their respective rungs, to a horizontal frame distance, preferably parallel to each other, and the scaffolding platform being supported or fixed upper in the additional frame and in the other frame, and being fixed or being fixed in the additional frame and in the other frame either a railing device comprising at least two railing elements or at least two railing elements, respectively rotatably with respect to these frames, being arranged and fixed or arranging and fixing the railing elements, considered in the direction of the steps of the additional frame and / or the other, laterally side by side at a distance from horizontal railing elements , preferably at a distance above the scaffolding platform, so that either the railing device, preferably as a back or hip protection element, serves to protect a person who is on the upper scaffold platform against falls or so that the railing elements, preferably as back or hip protection elements, serve as a pair to protect a person who is on the upper scaffolding platform against falls, removing the upper scaffolding platform to disassemble the scaffold on wheels, and being placed or placed a frame hooking device to hook a frame to be disassembled of the frames, which is supported by a frame mounted on the frames, especially on at least one of its steps, preferably on its highest step, and / or supported by the frame, and because the additional frame is disengaged and / or it is removed from the mounted frame or it is lowered together with the railing device fixed therein and also in the other frame in a rotatable manner with respect to these frames or together with the railing elements fixed therein and also in the another frame rotatably with respect to these frames, preferably by a person who is on the lower scaffolding platform, to a position where the additional frame is supported in the frame engagement device so that it can be disengaged again and / or in which the additional frame is engaged in the frame engagement device so that it can be disengaged again and in the supported and / or engaged state there adopts a transition position and / or starting from the supported and / or engaged state there is directed or transferred to a transition position, starting from which the additional frame, preferably after unhooking the railing device or the railing elements of the additional frame , can be removed or removed from the frame hitch device or the scaffold parts on wheels that remain mounted.

By means of these measures the dismantling of a scaffold on wheels can be carried out with greater security at every moment of dismantling in the event of falls of people on the scaffolding on wheels that is exploded.

Neither in case of assembly according to the invention nor in case of disassembly according to the invention of a scaffold on wheels is an additional part necessarily necessary.

According to an advantageous configuration of the procedure for assembling a scaffold on wheels it can be provided that initially a first frame and a second frame of the frames are constructed, considered in transverse direction with respect to their respective steps, at a distance of horizontal frames from each other, and that the lower scaffolding platform is supported or fixed in the first frame and in the second frame, and that either a railing device comprising at least two railing elements is fixed in the second frame or fixed to the minus two railing elements, the railing elements being arranged or arranged, preferably considered in the direction of the rungs of the second frame or of the frames, laterally next to each other at a distance of railing elements, especially horizontal, and either being fixed or by fixing the handrail device in a rotating manner with respect to the second frame in this one or else f The railing elements are fixed or fixed in a rotating manner with respect to the second frame in it, or that over

Examples of embodiment of three scaffolding on wheels 1.1 are shown in Figures 14, 37, 51; 1.2 .; 1.3 constructed according to the invention. Each scaffold on wheels 1.1; 1.2; 1.3 is constructed from a plurality of frames 20; 120; 220 vertical These respectively have two uprights 16.1, 16.2; 160.1, 160.2 parallels and steps 17; 217 connecting them and arranged perpendicularly to them for the ascent and / or descent of persons 52 and / or to engage scaffolding platforms 30; 130; 230, diagonal connection elements 50.1, 50.2; 51.1, 51.2 and / or horizontal connection elements 18.1, 18.2; 18.3, 18.4. Each scaffold on wheels 1.1; 1.2;

1.3 is built in this case with or on two mobile beams 2.1, 2.2. These are essentially formed by a horizontal support, from which each one has at each end a fitting tube 3.1, 3.2 that is vertical in the constructed state. The snap-in tubes 3.1, 3.2 serve respectively to accommodate a spindle 5 of a foot 4 of adjustable height by means of a nut 6. Each foot 4 comprises a base plate 7, in which a clamping roller 8 is usually fixed habitual. In the front spindle 5 in this case vertical tubes 10.1, 10.2 of a frame bar 9 are also referred to as a base tube. This piece offers a joint fastening of the respective mobile beams 2.1, 2.2 in the area respectively of one of its ends. Below each horizontal support of each mobile beam 2.1, 2.2, an auxiliary step 11 is fixed therein, in the case of the scaffold on wheels 1.1 and 1.2 and in the case of the scaffold on wheels 1.3, by means of two step stands 12.1, 12.2 vertical. The auxiliary steps 11, 111 are at a height such that in case of nuts 6 turned completely downwards, no contact with the ground occurs. Therefore they are in free space, which is created or created by feet 4 and rollers 8 (see Figures 1 and 51). Scaffold platforms or planks can be placed on the auxiliary steps 11, 111 and / or fixed there so that they can be disengaged, preferably with the help of interlocking nails. In the case of the scaffold on wheels 1.1 no scaffolding platform is placed on the auxiliary steps 11, while in the case of the scaffolding on wheels 1.2 a first scaffolding platform 130.1 or the lowest is placed on the auxiliary steps 11. In In the case of the scaffolding on wheels 1.3 wide, two first scaffolding platforms 230.1.1 and 230.1.2 or the lower ones are placed on the auxiliary steps 111 next to each other.

The length of the frame bar 9 or the horizontal distance between its two vertical tubes 10.1 and 10.2 determines the width of the respective scaffold on wheels 1.1; 1.2; 1.3 on its respective longitudinal side 65 and / or the distance of frames 21 (see Figure 2) or the distance of engagement between two frames of a floor 15.1 to 15.4, which rests on the respective mobile beam 2.1, 2.2. This length or this distance of frames 21 amounts to the examples of embodiment shown in the figures at 285 cm. However, it is understood that the length of the frame bar and / or the distance of frames may be greater than or less than 285 cm, especially it may amount to 180 cm.

On each of the mobile beams 2.1, 2.2 there is a frame 20.1, 20.2; 120.1, 120.2; 220.1, 220.2 vertical lower or lower. These are assigned to a first floor 15.1 or lower. In the case of scaffolding on wheels 1.1, these are respectively frames 20.1 and 20.2 below. Its construction height is twice as large as the construction height of frame 120.1 and 120.2 lower than the scaffold on wheels 1.2 and the construction height of frame 220.1 and 220.2 lower than the scaffold on wheels 1.3. In other words, it is therefore the construction height of the frame 120.1, 120.2; 220.1, 220.2 lower of the scaffolding on wheels 1.2 and 1.3 equally large and also only half as large as the construction height of the frame 20.1 and

20.2 lower scaffolding on wheels 1.1. The construction height of frames 120.1 and 120.2 as well as frames 220.1 and 220.2 amounts to 100 cm in the embodiment, while the construction height of the lower frames 20.1 and 20.2 of scaffolding on wheels 1.1 amounts to 200 cm . Corresponding to this is the number of steps 17.1, 17.2, 17.3, 17.4 of the frames 120.1 and 120.2 and the number of steps 217.1, 217.2,217.3, 217.4 of the frames 220.1 and 220.2, with respectively four steps, only half larger than the number of steps 17.1 to 17.8 of the respective frames 20.1, 20.2 of the scaffolding on wheels 1.1.

The steps 17; 217 are arranged to each other at equal vertical distances in this case. With the respective frames or within the respective frames ascends the distance of the steps 17 or 217 one under the other in this case respectively to 25 cm. However, it is understood that within a frame distances of steps of different dimensions can also be provided. This is especially so when the rungs do not work or are not specified to raise and / or lower people. In the embodiments shown in the figures, only the steps 17.1 are involved to carry out the assembly and disassembly method according to the invention,

17.4 and 17.5 or 217.1, 217.4 and 217.5. The steps 17.3 or 217.3 are provided in this case for safety reasons to fix the knee protection elements or knee protection bars 18.3 and 18.4. however, it is understood that double railing elements may also be provided, which may be specially fixed only on step 17.1 or 217.1. all other steps can also be suppressed if necessary.

The construction width of frames 20.1 and 20.2 of the scaffolding on wheels 1.1 and the width of construction of frames 120.1 and 120.2 of the scaffolding on wheels 1.2, respectively the horizontal distance of the longitudinal axes of the respective two uprights 16.1, 16.2 or 116.1, 116.2 of the respective frames 20.1, 20.2 or 120.1, 120.2 amounts to the examples of embodiment shown at 75 cm. However, it is understood that the construction width of the frames or the horizontal distance of their uprights per frame can also be smaller or larger. The latter is shown in the exemplary embodiment of the 1.3 wide wheel scaffold. There, frames 220.1 and 220.2 respectively have a construction width or a horizontal distance of their respective two uprights 116.1 and 116.2 that amounts to 150 cm. In order to reinforce or support the correspondingly longer steps 217.1 to 217.4 there, respectively, are provided two by two by means of vertical reinforcement elements 218.1. These are fixed in this case respectively in the center between the respective uprights 116.1 and 116.2 of the respective frame.

The first or lower scaffolding platform 30.1 is fixed in the case of scaffolding 1.1 on the respective step

17.5 of the respective lower frame 20.1 and 20.2, while in the case of scaffolding on wheels 1.2, the first or lower scaffolding platform 130.1 is fixed on the respective auxiliary step 11 of the respective mobile beam 2.1,

2.2. In the case of scaffolding on wheels 1.3, the two scaffolding platforms 230.1.1 and 230.1.2 that are located next to each other or lower are fixed on the respective auxiliary step 111 of the respective mobile beam

2.1 and 2.2. The respective distance of the auxiliary steps 11, 111 to the lower step 17.4 or 217.4 of the respective frame 20.1, 20.2 or 120.1, 120.2 or 220.1, 220.2 is greater than the conventional distance of steps within the frames. This distance amounts in this case to 37.5 cm.

In each of the frames 20.1, 20.2; 120.1, 120.2 or 220.1, 220.2 lower which are located on the mobile beams 2.1 and 2.1 respectively, an additional vertical frame 20.3, 20.4 or 220.3, 220.4 is fitted, and specifically so that the vertical plane respectively fixed by these additional frames coincides with the respective vertical plane respectively fixed by frames 20.1, 20.2; 120.1, 120.2; 220.1, 220.2 lower or lower that support it and arranged below it. Accordingly, therefore also the additional frames 20.3, 20.4 or 220.3, 220.4 of the now respectively second floor 15.2 have the same distance of frames 21 from each other, as frames 20.1, 20.2; 20.1, 120.2 or 220.1, 220.2 of the respective lower floor 15.1. These frames 20.3, 20.4; Additional 220.3, 220.4 are, in the examples of embodiment shown, all of the same length or all have a construction height of the same size that amounts in this case to 200 cm. However, it is understood that the construction length or height may also be shorter or longer and / or that the construction length or height of the additional frames of the different wheel scaffolds may also be of different dimensions.

Scaffold platforms 30.2 are fixed in the examples shown in the figures; 230.2 additional or second or higher in respectively horizontal position so that they can be disengaged on the steps 17, 217 of the frames 20.3, 20.4; 220.3, 220.4 assigned to respectively second floor 15.2. In the case of scaffolding on wheels 1.1 and 1.2, the additional or superior or second scaffolding platform 30.2 is respectively fixed so that it can be disengaged respectively on a step

17.5 of the respective framework 20.3 and 20.4. In the case of scaffolding on wheels 1.3, the scaffolding platforms 30.2 and 230.2 are arranged next to each other, assigned to the second floor 15.2 on the respective step 217.5 of frames 220.3 and 220.4.

In the case of scaffolding on wheels 1.2 and 1.3, the scaffolding platform 130.1 or 230.1.1 is arranged and

230.1.2 of the respective first floor 15.1 and the scaffolding platform 30.2 or 30.2 and 230.2 of the respective second floor

15.2 each other at a vertical distance that amounts in this case 212.5 cm. In contrast to this, in the case of scaffolding on wheels 1.1, the vertical distance of the scaffolding platform 30.1 respectively lower than the first floor 15.1 of the respective scaffold platform 30.2 immediately above the same one on the second floor amounts to 200 cm. The vertical distance of the respective second scaffolding platform

30.2 or 230.2 of the immediately superior scaffolding platform arranged respectively above it of the third floor 15.3 respectively in this case also amounts respectively to 200 cm. This distance is also maintained for eventual, additional scaffolding platforms located immediately above.

Preferably, all the scaffolding platforms of at least the second and of each additional upper floor 15.3, 15.4 are fixed with the aid of interlocking nails 55 so that they can be disengaged again on rungs of the frames. Basically the same is also true for scaffolding platforms 30.1, 30.2; 230.1.1,

230.1.2 lower or first. At least these can be placed however, especially in the cases of scaffolding on wheels 1.2 and 1.3, also only on the auxiliary steps 11 or 111 or on the rungs of the frames, therefore they can also be configured as scaffolding boards, for example wooden planks.

In the case of scaffolding on wheels 1.1, two diagonal frames 51.1 and 51.2 are provided for reinforcement of the two lower frames 20.1 and 20.2. These have at their two ends respectively interlocking nails 55, by means of which they are fixed in this case on step 17.8 of frame 20.1 and on step 17.5 of frame 20.2 so that they can be disengaged. These diagonals 50.1 and 50.2 have an engagement length of 295 cm in the exemplary embodiment. These diagonals 51.1 and 51.2 are arranged in this case parallel to each other. However, they can also be arranged cross-linked or cross-linked. Unlike this, diagonals 50.1 and 50.2, which are used or used for the bracing of the first 15.1 floors of scaffolding on wheels 1.2 and 1.3, have a length that in this case amounts to 335 cm. In addition, these diagonals 50.1 and 50.2 are respectively fixed in a cross-linked manner or arranged in a cross. For this, in the case of the scaffolding on wheels 1.2, the diagonal 50.1 is fixed so that it can be disengaged with a locking nail 55 on the bottom step 17.4 of the lower frame 120.1 and with its locking nail 55 provided at the other end on the step 17.5 of the upper frame 20.3. The other diagonal 50.2 is fixed so that it can be disengaged at one end with an interlocking nail 55 on the bottom step 17.4 of the other lower frame 120.2, while it is fixed so that it can be disengaged at the other end with an interlock nail 55 in the step 17.5 of the other upper frame 20.4. The same can be said of the scaffolding on wheels 1.3. There the diagonal 50.1 is fixed at one end with an interlocking nail 55 so that it can be disengaged on the lower step 217.4 of the lower frame 220.1 and at the other end by means of an interlocking nail 55 on the step 217.5 of the frame 220.3 upper while the other diagonal

50.2 is fixed at one end on the lower step 217.4 of the other lower frame 220.2 and at the other end on the step 217.5 of the other upper frame 220.4, respectively with an interlocking nail. In this way the scaffolding on wheels 1.1 is braced; 1.2; 1.3 sufficiently in front of the slope and / or turn.

Scaffolds on wheels 1.1 and 1.2 are constructed in this case with a total of three floors 15.1, 15.2., 15.3 with respectively three positions or levels, which are formed respectively with a scaffolding platform 30.1, 30.2, 30.3. The scaffolding on wheels 1.3 is built in this case with a total of four floors 15.1, 15.2, 15.3,

15.4 with respectively a position or level formed with respectively two scaffolding platforms 230.1.1, 230.1.2; 30.2, 230.2; 30.3, 230.3; 30.4, 230.4 that are next to each other.

Scaffolding on wheels 1.1; 1.2; 1.3 constructed according to the invention are constructed in this case respectively based on a construction unit with at least four frames. Of these four frames respectively two frames are assigned to a lower floor, while the other two frames are assigned to an immediately higher floor. In this respect, two of the frames are constructed respectively on one another, preferably placed one on the other. However, it is understood that a construction according to the invention and / or an exploded view according to the invention of a scaffold on wheels or that an assembly and / or disassembly according to the invention of a scaffold on wheels can also be carried out or carried out based on construction units with only three frames, if necessary also with only two frames. In the case of a construction unit consisting of three frames, two frames are constructed or constructed one on top of the other, preferably placed one on top of the other, while the third frame is constructed or constructed at a horizontal frame distance. with respect to the other two frames. In the case of a construction unit consisting of only two frames, these frames are constructed or constructed at a distance of horizontal frames from each other.

At least the second and each floor 15.2 to 15.4 additional or plant scaffolding on wheels 1.1; 1.2; 1.3 are secured, towards their respective longitudinal sides or outer sides 64.1 and 64.2, with in this case respectively four railing elements 18.1, 18.2., 18.3, 18.4, so that a person 52 is protected against falls the scaffolding platform that will be secured or on the scaffolding platforms that will ensure these plants or floors 15.1, 15.2, 15.3, 15.4. For this purpose they are fixed so that knee protection elements or bars can be disengaged at knee height 18.3 and 18.4 respectively between the two frames arranged at equal height and spaced apart from each other at a distance from frames, in this case in their rungs, and specifically in this case with interlocking nails 55 provided at both ends. The knee-high bars 18.3 and 18.4 are respectively constructed at a distance above the scaffolding platform to be secured or above the respective scaffolding platforms to be secured. This distance corresponds in this case to the distance of three successive steps one above the other, so in this case it amounts to approximately 50 cm.

Parallel to the knee-high bars 18.3 and 18.4 and also parallel to the scaffolding platforms 30; 130; 230 to be secured are additional rail elements 18.1 and 18.2 provided that serve as back and hip protection elements to protect a person 52 who is on the platform to be secured or on the scaffolding platforms 30; 130; 230 they will make sure. These additional railing elements 18.1 and 18.2 are also fixed so that they can be disengaged in the respective two frames arranged with each other at the same height at a distance from frames. In this case, it is also fixed by means of interlocking nails 55 provided at both ends, which in this case are fixed on or on the rungs of the respective frames.

The vertical distance 53 of these railing elements 18.1 and 18.2 to the scaffolding platforms to be secured respectively corresponds in this case to a distance of five successive steps 17, 217 one above the other, therefore in this case amounts to approximately 100 cm. Consequently, the vertical distance of these railing elements 18.1 and 18.2, which act as back or hip protection elements, of the railing elements or bars at knee height 18.3 and 18.4 set respectively below amounts in this case. respectively at approximately 50 cm.

An assembler 52 initially constructs a unit composed of the two movable beams 2.1 and 2.2, the four feet 4 with the four clamping rollers 8 and with the frame bar 9. For this purpose, the assembler 52 puts the spindles 5 of the feet 4 provided with the clamping rollers 8 in the respective nesting tubes 3.1, 3.2 of the respective mobile beams 2.1, 2.2, in which or according to which it places the mobile beams 2.1 and 2.2 previously mounted in this way, equipped with the rollers clamping 8 at a sufficiently large or adequate distance from each other on the ground. Next, the assembler 52 picks up the rack bar 9 in the area of a vertical tube 10.1 or 10.2 and places this vertical tube on the free end of a spindle 5 protruding from an embedded tube 3.1 or 3.2 of one of the movable beams 2.1 or 2.2.

Next, the assembler goes with the frame bar 9 fixed at one end in the first mobile beam 2.1 towards the second mobile beam 2.2, this sliding the frame bar 9 by its hand and then also placing the second vertical tube 10.2 of the frame bar 9 on the free end of a spindle 5, which protrudes from the snap-in tube 3.1 of the second movable beam 2.2 upwards. Thus, then, the spindles 5 of the two mobile beams 2.1 and 2.2 are oriented vertically or perpendicularly, so that the mobile beams 2.1 and 2.2 are then prepared for the additional construction of the scaffold on wheels 1.1. For this purpose, the assembler 52 disposes the two movable beams 2.1 and 2.2 approximately perpendicular to the frame bar 9. It is understood that it can be arranged or fixed at the other ends of the movable beams 2.1 and 2.2, especially in or on the spindles protruding up there vertically, also an additional horizontal connection element, for example an additional frame bar.

Following the preparation of the base unit constructed approximately U-shaped or rectangular, composed of the two movable beams 2.1 and 2.1 with their respective two clamping rollers 8 and with the frame bar 9 that joins the two beams mobile 2.1 and 2.2, the assembler 52 places or puts a frame 20.2

vertically on the mobile beam 2.2. Following this, the assembler fixes the two railing elements 18.1 and

18.2 with its interlocking nails 55 provided at respectively one end so that it can be disengaged and rotatably with respect to the frame 20.2 at or on its highest step 17.1. Following this, the assembler 52 or an additional assembler, which is not shown in the figures, brings a second frame 20.1, in which or according to which the assembler 52 fixes the two railing elements 18.1 and 18.2 with its nails interlocking 55 provided at the other end on or on the step 17.1 higher of the second frame 20.1, rotatably with respect to this frame 20.1 and also so that it can be disengaged. Following this, the assembler 52 can drive up the frame 20.1 supported so far still on the ground together with the two railing elements 18.1 and 18.2 fixed therein and also in the other frame 20.2 to a position where or according to which it places or fits the second frame 20.1 on the mobile beam 2.1.

Figure 2 shows the construction situation in which the two frames 20.1 and 20.2 are placed or fitted on the respective mobile beams 2.1 or 2.2. It also follows that the assembler following the above-described assembly of the two frames 20.1 and 20.2 and the two railing elements 18.1 and 18.2 incorporates the two diagonals 51.1 and 51.2 as well as a first scaffold platform 30.1. This is, in this case, a so-called scaffolding platform. However, it is understood that instead of a scaffolding platform, a scaffolding platform without a passage opening can also be used. The assembler then climbs outside, especially from the ground, to this scaffolding platform. Accordingly, this scaffolding platform 30.1 has a passage opening 31, whereby a person or an assembler 52 can climb from a lower level, that is to say from the ground, to the corresponding scaffolding platform, that is to say the scaffolding platform 30.1. The passage opening 31 can be closed by a cover not shown in the figures or with a hatch not shown, so that the person or the assembler 52 can then also be on the cover or on the hatch. As is evident from Figure 2, the diagonals 51.1 and 51.2 are fixed parallel to each other between the two frames 20.1 and 20.2, so that their interlocking nails 55 provided by one end are respectively fixed on the step 17.8 lower of the frame 20.1 and that the interlocking nails 55 provided by the other end of the diagonals 51.1 and 51.2 are respectively fixed on a step 17.5 of the other frame 20.2, also so that they can be disengaged. Next or previously, the 30.1 scaffold platform was fixed in both frames 20.1 and

20.2 constructed from each other at a distance of frames 21, so that this scaffolding platform 30.1 is fixed on or on the respective step 17.5 of the respective frame 20.1 and 20.2, preferably also with the aid of interlocking nails so that it can be disengaged again .

The other additional construction is illustrated in Figure 3. From this it follows initially in comparison with Figure 2 that the assembler 52, after it has risen from the ground through the passage opening 31 of the scaffolding platform 30.1 up to this, in this case lower, or a 30.1 scaffolding platform, has fixed below rail elements 18.1 and 18.2 that serve as back or hip protection elements, additional rail elements in the form of bars at height of the knee 18.3 and 18.4 so that they can be disengaged on the steps 17.3 of the two frames 20.1 and 20.2. Following this, the assembler located on the scaffolding platform 30.1 takes two elongated scaffold pieces in the form of diagonals 50.1 and 50.2 by hand, which have been reached by a second assembler not shown in the figures. These two diagonals

50.1 and 50.2 have interlocking nails 55 at their respective ends. The assembler 52 now assembles the two diagonals 50.1 and 50.2 at a horizontal distance 84 from each other, so that they are fixed at one end with one of their respective interlocking nails 55 in or on a step 17.4 of the frame 20.2, so that these ends then configure fixing ends 68. In the area of their other free ends, which are also provided with interlocking nails 55, diagonals 50.1 and 50.2 are supported respectively on the step 17.1 higher than the frame 20.1. Said free ends of diagonals 50.1 and 50.2 protrude with the configuration of engagement ends 67 through the vertical plane fixed by the uprights 16 and steps 17 of the first frame 20.1 in the direction of the second frame 20.2 outwards. These two diagonals 50.1 and 50.2 then, when assembled in the manner described above, together form a frame engagement device 50 to engage an additional frame 20.4. As is also evident from Figure 3, an additional frame 20.4 can therefore be hooked, which another assembler, not shown in the figures, has reached up to the assembler 52, in the frame engagement device 50 formed by the two diagonals 50.1 and 50.2, so that an additional step of the frame 20.4, in this case its step 17.5, is placed on top or rests there in the area of the engagement ends 67 free of the respective diagonals 50.1 and 50.2. Conditional on the inclined construction position of the two diagonals 50.1 and 50.2, the assembler 52 can release the additional frame 20.4 thus hooked on the frame engagement device 50, so that it is then hung in the vertical position shown, that is perpendicularly in the two diagonals 50.1 and 50.2 in a transition position 40, and specifically also protects against falls as a result of wind forces that occur eventually. Before or after engaging the additional frame 20.4 in or on the diagonals 50.1 and 50.2 that configure a frame engagement device 50, the assembler 52 can fix on the second frame 20.2 a third frame 20.3, preferably fit. Next, the assembler 52 can fix on the step 17.1 higher of the third frame 20.3 an additional railing element 18.2, fixing this by means of an interlocking nail 55 provided by one end so that it can be disengaged on the step 17.1 of the third frame 20.3 rotatably with respect to it. Following this, the assembler 52 can go with the railing element

18.2 in the hand towards the additional 20.4 frame. This is supported by diagonals 50.1 and 50.2 that configure a frame hooking device 50 on the step 17.1 higher of the first frame 20.1 and protrudes with an essential part 82 through the frame 20.1 upwards. Next, the assembler 52, which holds the handrail element 18.2 in the area of its free end or the locking nail 55 provided therein, can grasp the additional frame 20.4 with its other hand, especially in its part 82 protruding upwards through its support position in diagonals 50.1 and 50.2 or through the first frame 20.1 and then you can rotate the additional frame 20.4 in a direction of rotation, which is characterized in figure 3 with an arrow 86, in direction to the third frame 20.3 mounted opposite so much until it can fix the locking nail 55 provided at the free end of the railing element 18.2 on or on the step 17.1 higher of the additional or fourth frame 20.4, after which it also then performs the corresponding fixation. Next, a construction position is achieved as shown in Figure 4. In this construction position, therefore, the additional or fourth frame 20.4 is still supported on the coupling ends 67 of the two diagonals 50.1 and 50.2 that make up the device of hitching frames 50, however in an angular position opposite to the perpendicular and specifically in an additional transition position 40.1. Following the fixing of the railing element 18.2 on the step 17.1 respectively higher of the frames 20.3 and 20.4, it can be fixed so that an equal railing element 18.1 can be disengaged at one end with its locking finger 55 on the step 17.1 higher of the third frame 20.3 and at the other end on the step 17.1 higher of the additional or fourth frame 20.4 by means of the locking nail provided therein, and specifically at a horizontal distance 19 of these railing elements 18.1 and 18.2 from each other . The mounting situation achieved below is illustrated in Figure 4. Starting from this additional transition position 40.1, on which the additional or fourth frame 20.4 is supported still on the frame engagement device or on the 50.1 and 50.2 diagonals, it can now be transferred, as illustrated in Figure 5, the additional or fourth frame 20.4 together with the railing elements 18.1 and 18.2 fixed therein and also in the third frame 20.3 respectively so that they can be disengaged and rotatably respectively with respect to these two frames 20.3 and 20.4, upwards to a position where the additional or fourth frame 20.4 can be fixed, preferably fitted, on the first frame 20.1.

To this end, the assembler 52, starting from the transition position 40.1 shown in Figure 4, grabs the frame

20.4 additional or fourth as low as possible, preferably in their uprights 16.1 and 16.2, and then move the additional frame 20.4 in a type of upward curved path, so that its lowest step 17.8 can be directed forward upwards to the free ends 67 of diagonals 50.1 and 50.2, as illustrated by way of example in the partial phase according to Figure 5.

Next, the assembler 52 can, as described above, place or fit the additional or fourth frame 20.4 on the lower or first frame 20.1, so that the construction position shown by way of example in the figure is then achieved 6. In this mounting position there is therefore the first and fourth frames 20.1 and 20.4 and also the second and third frames 20.2 and 20.3 respectively in a vertical position, where the fixed vertical planes coincide or are aligned with each other by the respective frames or their uprights and rungs of the frames mounted one above the other. Furthermore, in this mounting position shown in Figure 6, the rail elements 18.1 and 18.2 are then arranged fixed on the upper ends or on the upper rungs 17.1 of the two frames 20.3 and 20.4, parallel to the rail elements 18.1 Y

18.2 equals set below at a distance of in this case eight successive steps 17 one above the other parallel to these. This vertical distance between the rail elements 18.1, 18.1 and 18.2, 18.2 of the first and second floor or floor 15.1 and 15.2 in this case amounts to 200 cm.

Following this, the assembler 52 disengages the two diagonals 50.1 and 50.2 of the second frame 20.2, respectively from its rung 17.5, and then recesses these two diagonals 50.1 and 50.2 on the scaffold on wheels 1.1 that is under construction, such as It is shown by way of example in Figure 7. In other words, the frame engagement device 50, which is configured in this case by the two diagonals

50.1 and 50.2, can then be embedded in the scaffold on wheels 1.1 that is being built or is then embedded in the scaffold on wheels 1.1 to be built or built. For this purpose, diagonal 50.1 can be fixed with the locking nail 55 provided at one end of the step 17.4 of the first frame

20.1 and can be fixed at the other end with the locking nail 55 provided there on step 17.5 of the third frame 20.3. In addition, the other diagonal 50.2 can be fixed at one end with its retaining nail 55 on the step

17.4 of the second frame 20.2 and can be fixed at the other end with its locking finger 55 on step 17.5 of the additional or fourth frame 20.4. Next, the two diagonals 50.1 and 50.2 are embedded in the scaffold on wheels 1.1 to be constructed or built crosswise or crosswise.

Following this, the assembler 52, which is still on the lower or first scaffolding platform 30.1, can incorporate an additional or second or higher scaffolding platform 30.2 in a situation or position, as shown for example in the figure 8. Accordingly, the second or additional or higher scaffolding platform 30.2 can be fixed or fixed respectively on the steps 17.5 of the third frame 20.3 and the fourth frame 20.4 so that it can be disengaged, so that the scaffolding platform is next

30.2 additional or second or higher may be arranged parallel to the scaffold platform 30.1 lower or first and at a distance that in this case amounts to 200 cm. In this respect, the upper or additional or second scaffolding platform 30.2 is incorporated, in which case it is also a step scaffolding platform, so that its passage opening 31 is in this case arranged perpendicularly through of the passage opening 31 of the lower or first scaffolding platform 30.1. However, it is understood that the scaffolding platforms of successive floors 15 on one another can be incorporated or incorporated respectively 180 degrees apart from each other, so that their passage openings 31 are arranged alternately respectively, with respect to the perpendicular. This type of assembly has the advantage that a person, in the event of an open passage opening, may not fall completely down, but only up to the scaffolding platform immediately following down. The mounting of the additional or second or higher scaffold platform 30.2 is carried out at a distance 53 below the highest railing elements 18.1 and 18.2, so that or in which these railing elements 18.1 and 18.2 then configure a railing advanced Otherwise, these railing elements 18.1 and 18.2 then form back or hip protection elements to protect a person who is on the second or additional or higher scaffolding platform 30.2, in this case the assembler 52, against falls .

Following the assembly of the additional or second or higher scaffolding platform 30.2, the assembler 52, which has so far remained on the first floor 15.1 or floor on the first or lower scaffold platform 30.1, climbs through the opening of step 31 of the second or higher or additional scaffolding platform 30.2 up to this additional or second or higher scaffolding platform 30.2 and is then protected, when it is on the second or additional or higher scaffolding platform 30.2, already effectively by the advanced railing in front of falls, which is formed by the two railing elements 18.1 and 18.2, which configure back or hip protection elements against falls.

Provided that a scaffold on wheels should be constructed even higher, then the scaffold on wheels with at least one additional floor, in this case the 15.3 floor, can be built additionally, as illustrated in Figures 9 to 14. The main course in the case of additional construction is in this respect the same as described previously in relation to the construction of the pieces for the second scaffold floor

15.2. Accordingly, the additional construction can be carried out starting from figure 9, which corresponds to the construction sequence from figure 4, as follows:

In the first place, the assembler 52 incorporates the two bars at knee height 18.3 and 18.4 once. Next, the two future diagonals 50.1 and 50.2 are incorporated as or in the configuration of a frame engagement device 50. Next, an additional frame 20, which is characterized in this case correspondingly to the construction sequence according to the invention with a construction unit of four individual frames, with the reference number 20.4 '. In the vertical or perpendicular hitching position, this additional frame 20.4 'is then in the transition position 40', where it is arranged on the outer side 81 of the scaffold on wheels 1.1 limited by the uprights 16.1 and 16.2 and steps 17 of the frame 20.4 or thereafter 20.1 'and in which it, preferably again with half its length, protrudes from the respective frame 20.4 or 20.1' upwards. Previously or subsequently, the additional frame 20.3 'can be fitted or placed on the frame 20.3 or thereafter 20.2' and it can be fixed thereon, preferably again on its step 17.1, a railing element 18.2 with an interlocked nail 55 at one end so that it can be disengaged. Following this, the additional frame 20.4 'or its piece 82 projecting upwards in the direction of rotation 86 can be turned, after which the other end of the railing element 18.2 with its locking nail 55 can be fixed on the step 17.1 higher than the additional 20.4 'frame so that it can be disengaged. Following this, an additional scaffolding element 18.1 can also be fixed with the aid of its locking nail in or on the step 17.1 higher of the frame 20.3 'and in or on the step 17.1 higher of the additional frame 20.4' so that It can disengage. Next is the additional frame 20.4 'in a suitable additional transition position opposite to the perpendicular, which is illustrated in Figure 10. Next, this can be turned upwards, as illustrated in Figure 11, the frame 20.4 'additionally together with the railing elements 18.1 and 18.2 fixed therein and in the frame 20.3' so that they can be disengaged and rotatably with respect to these frames 20.4 'and 20.3', and specifically to a position, from where it can be fixed the additional frame 20.4 'on the frame 20.4 or 20.1', preferably by engagement, and according to this it is also fixed or fitted, as shown by way of example in Figure 12.

Following this, the elongated 50.1 and 50.2 scaffolding parts that previously act as frame hook elements can be removed and can be embedded in their function as diagonals 50.1 and 50.2 on the scaffold on wheels 1.1 to be constructed, as illustrated this for example in figure 13.

Following this, the assembler 52 found for this on the scaffolding platform 30.2 or now 30.1 ’assembles the third scaffolding platform 30.3 (figure 14). In the case of this scaffolding platform it is treated in the current construction sequence with four frames of the 30.2 ’superior or then second scaffold platform. This is mounted at a vertical distance 53 below the two railing elements 18.1 and 18.2 thereafter the highest, which form an advanced railing, and specifically again at a vertical distance to a 30.2 or 30.1 'scaffold platform that is found below, which corresponds to the distance of this scaffolding platform from the first scaffolding platform 30.1 and consequently ascends in the embodiment example to approximately 200 cm.

Following this, the assembler, who has previously remained on the second scaffolding platform

30.2 or 30.1 ', can climb up through the passage opening 31 of the third scaffold platform 30.3 or 30.2' to this higher 30.3 or 30.2 'scaffold platform and is then protected in this respect from the beginning against falls by means of the railing elements 18.1 and 18.2 that respectively configure a back or hip protection element. Following this, the assembler 52 can also mount the two bars at knee height 18.3, 18.4 and shelves 85.1 and 85.2, so that then on the 15.3 floor or higher floor, which is formed with the platform of 30.3 or 30.2 'higher scaffolding, optimally safe work is possible. According to this, Figure 14 shows a scaffold on wheels 1.1 constructed with three floors 15.1 to 15.3 according to the invention.

The disassembly according to the invention of this scaffold on wheels 1.1 is illustrated by figures 14 to 24 and the construction sequence that results from the same and is described in more detail below:

Starting from the scaffold on wheels 1.1 constructed in a finished way according to figure 14, the assembler 52 first disassembles the two bars at knee height 18.3 and 18.4 on the 15.3th floor higher and throws them down. Next, the assembler 52 slides through the passage opening 31 of the scaffolding platform 30.2 ′ or 30.3 higher towards the scaffolding platform 30.2 or 30.1 ’below. From there, the assembler 52 then disassembles the scaffold platform 30.2 ’or 30.3 higher and also throws it down. Following this, the assembler 52 disassembles the two diagonals 50.1 and 50.2 and then again incorporates these as a frame engagement device 50 for example to a position shown in Figure 15. For this purpose the diagonals 50.1 and 50.2 with its interlocking nails 55 provided at one end on a step 17.4 of the frame 20.2 ", 20.4, 20.3" 'mounted below the frame 20.3 "or 20.4' higher, and specifically at a horizontal distance 84 from each other. zone of its other free ends, diagonals 50.1 and 50.2 rest on the step 17.1 of the highest frame 20.3, 20.1 ", 20.4" 'mounted opposite, as also illustrated in figure 15. The diagonals 50.1 and 50.2 then fixed thus with their fixing ends 68 on the step 17.4 of the frame 20.2 ", 20.4, 20.3" 'then protrude with their free ends towards their fixing ends 68 through the frames 20.3, 20.1 ", 20.4"' out, so that the extreme s free of diagonals 50.1 and 50.2 can then serve as free hook ends 67 to engage a frame to be removed, in this case frame 20.3 ’, 20.4", in a transitional position.

After the incorporation of diagonals 50.1 and 50.2 with the configuration of a frame hooking device 50, the assembler 52 located on the scaffolding platform 30.2, 30.1 'removes the frame 20.3', 20.4 "together with the railing elements 18.1 and 18.2 fixed therein and in frame 20.3 ", 20.4 'of frame 20.3, 20.1", 20.4 "' and then move frame 20.3 ', 20.4" down, so that its lower step 17.8 is directed by in front of the coupling ends 67 free of diagonals 50.1 and 50.2, after which it supports the frame 20.4 ", as illustrated in Figure 16, preferably with its step 17.5, on the coupling ends 67 free of the diagonals 50.1 and 50.2. Then the frame 20.4 "is in the inclined position shown in Figure 16, in which case it is a transitional position. Starting from this transitional or inclined position of the frame 20.4", the assembler 52 then disengages the two railing elements 18.1 and 18.2 of the frame 20.4 ", after which it fixes these two railing elements 18.1 and 18.2, preferably, placing them on their shoulders or fixing them on a shoulder and in one hand, after which they can release the 20.4 "frame to be disassembled. This then leads the frame 20.4 "to rotate in a direction of rotation according to the arrow 87 shown in Figure 16, only by the force of gravity attacking it, to a vertical or perpendicular transition position 40", as shown in Figure 17, rotating the frame 20.4 "in this respect around the horizontal axis of rotation 57 illustrated in Figures 16 and 17. Next, the assembler 52 can fold the two railing elements 18.1 and 18.2 in the direction of the arrow 58 on or in the frame 20.3 "or allowed to fold in a manner conditioned by the force of gravity, so that the two railing elements are next

18.1 and 18.2 still fixed through their interlocking nails 55 on the upper step 17.1 of the frame 20.3 "and hung there, in a position as illustrated in Figure 18.

The disengagement of the rail elements 18.1 and 18.2 of the frame 20.3 ", respectively of its higher step 17.1, can be conveniently carried out with the help of an elongated scaffold piece, which was previously embedded in the scaffold on wheels 1.1. Especially suitable for this it is a bar at knee height 18.3 or 18.4, using the bar at knee height 18.3 in figure 18. In order to disengage the respective rail elements 18.1 and 18.2 of frame 20.3 "the knee-high bar 18.3 on that step 17.1 immediately below on which the respective railing element 18.1 or 18.2 is fixed, with an end 62 then serving as the handling end on step 17.2 of frame 20.3 "and at same time is placed on a nail not shown in the figures of the respective locking nail 55, with which the respective railing element 18.1 and 18.2 is fixed in the frame 20 .3". Then, by a rotation of the bar at knee height 18.3 around a rotation axis 63 that extends parallel to the step

17.2

in a plane of vertical rotation in the direction of the arrow 88, the nail is retracted against the elastic forces acting thereon until the affected rail element 18.2 or 18.1 can disengage from the step 17.1, after which the respective railing element 18.2 or 18.1 of this step 17.1. This procedure is used to disengage or disassemble the two railing elements.

18.1

and 18.2 higher from frame 20.3 ", after which these two railing elements 18.1 and 18.2 can be pulled down. Then frame 20.3" is removed and diagonals 50.1 and 50.2 that previously act as a hitch device are also removed of frames 50 as well as the bar at knee height 18.4 so far still mounted, after which these scaffolding pieces can also be pulled down. The pieces of scaffolding on wheels 1.1 that still remain are then shown in Figure 19.

To remove the now higher scaffolding platform 30.2, the assembler 52, which is so far there, slides down through the passage opening 31 of this scaffolding platform 30.2 to the lowest or first scaffold platform 30.1 , from where the assembler 52 pulls the scaffold platform 30.2 higher or second and can throw it down. Following this, the diagonals 50.1 and 50.2 that remain are removed and in turn incorporated again with the configuration of a frame engagement device 50, as already described above. The diagonals 50.1 and 50.2 are therefore fixed with the locking nail 55 provided at its ends on the step 17.4, that is to say in this case on the lower step, of the frame 20.3 "', placing these in the area of their free ends on the upper step 17.1 of the frame 20.1 '' mounted opposite, so that its free ends can then act as hook ends 67 to engage the additional frame 20.4 "'to be removed. Then the frame 20.4"' is removed of the frame 20.1 "'and preferably rests with its step 17.5 on the hooking ends 67 of diagonals 50.1 and 50.2 or is engaged there, again in a transition or inclined position, as illustrated in Figure 20.

Starting from this transitional or inclined position of the frame 20.4 "', the assembler 52 can then unhook the two highest railing elements 18.1 and 18.2 of the frame 20.4"' and then let the frame 20.4 "'rotate in the transition position 40 '"vertical or perpendicular shown in Figure 21, in which the frame 20.4"' is then hung only by the diagonals 50.1 and 50.2 supported on it. Next, the assembler 52 can rotate the two railing elements 18.1 and 18.2 higher, which are still fixed on the step 17.1 higher of the frame 20.3 "', in the direction of the arrow 58 in or on the frame 20.3"' or can be rotated there, so that they are finally hung in the vertical position which follows from figure 22 on step 17.1 higher of frame 20.3 "'.

Following this, the assembler 52 removes one of the bars at the knee 18.3 or 18.4 again, in this case the bar at the knee 18.3 of the remaining part of the scaffold on wheels 1.1 and uses this rod at knee height 18.3 then as an auxiliary means of disassembly to disengage the rail elements 18.2 and 18.1 from the step 17.1 higher of the frame 20.3 "'. For this purpose the corresponding rod at the knee height 18.3 is supported. again on the second step 17.2 higher and at the same time it is placed on the not shown nail of the interlocking nail of a railing element 18.2 or 18.1 to be removed and then rotated in the direction of arrow 88 both until the respective railing element 18.2 or 18.1 can be disengaged from step 17.1 higher than frame 20.3 "'. Next, the assembler 52 disengages the corresponding railing elements 18.1 and 18.2 and can then pull them down.

Next, the assembler 52 removes the second bar at knee height 18.4 and the two diagonals 50.1 and 50.2 that remain, which until now last act as a frame hitch device 50 or frame hitch elements as well as the frame 20.3 "'. Then the assembler slides from the scaffolding platform 30.1 that is still through this passage opening 31 to the ground, from where you can disassemble the scaffolding platform 30.1 that is last. The pieces of the Scaffolding on wheels 1.1 that still remain are then shown in Figure 23. Now, the assembler 52 that is on the ground can remove one of the remaining frames, for example as shown in Figure 24, the frame 20.2 "', of the mobile beam 2.1 and place it on the ground. Then, the assembler can unhook from this frame 20.2 "'the two remaining rail elements 18.1 and 18.2. Then the frame 20.2"' and the two rail elements 18.1 and 18.2 can be removed, which are still fixed with help of their interlocking nails 55 on the step 17.1 higher of the remaining frame 20.1 "', can be turned in or on it to an upright position, after which these two rail elements 18.1 and 18.2 of the frame can also be manually disengaged 20.1 "'. Finally, the frame 20.1 "of the mobile beam 2.2 is also removed. Then the frame bar 9 is removed and also the remaining parts can be removed or removed.

The assembly and disassembly of the scaffolding on wheels 1.2 is illustrated by figures 25 to 46. The construction of an advanced railing, which in this case is also built at home floor 15.1 to 15.3 respectively with two railing elements 18.1 and 18.2 forming respectively back or hip protection elements, and also the disassembly is carried out mainly the same, as described and shown by the example of realization of the scaffolding on wheels 1.1 according to figures 1 to 24. A main difference in the construction or disassembly of the scaffolding on wheels 1.2 is that it is constructed starting from lower frames 120.1 and 120.2, whose construction length is in this case only half as large as the construction length of the lower frames 20.1 and 20.2 of the scaffolding on wheels 1.1. The preparation for placing the two said frames 120.1 and 120.2 of the scaffold on wheels 1.2 on the mobile beam 2.1 and 2.2 is carried out in the same manner, as described above in relation to the construction of the scaffold on wheels 1.1, so that for reasons You can easily refer to it. A unit composed of at least the two mobile beams 2.1 and 2.2 is therefore formed again, the four four holding rollers 8 fixed thereon and at least one frame bar 9, which join the two mobile frames 2.1 and 2.2. Unlike the scaffolding on wheels 1.1, a first or lower or lower scaffolding platform 130.1 is supported or fixed, to construct the scaffold on wheels 1.2, on or on the respective auxiliary steps 11, which are fixed below the respective horizontal support of the respective mobile beams 2.1 and 2.2 in these, in case of which it is for example a scaffold plank. In the mobile beam 2.1 and 2.2, one of the short frames 120.1 and 120.2 is placed or fitted respectively. In this way, the construction situation shown in Figure 25 is obtained. Starting from this, the lower step 17.4 of the second frame 120.2 is fixed at a horizontal distance 84 between them two diagonals 50.1 and

50.2 by means of their interlocking nails 55 provided by one end, so that these ends then act as fixing ends 68. In the area of their other ends, diagonals 50.1 and 50.2 are supported.

on the step 17.1 highest of the first frame 120.1 placed opposite, extending out its free ends of the frame 120.2 extending out of the frame 120.1 and thus being able to act as free hook ends 67 to engage an additional frame 20.4 that goes to be mounted in a transition position 40.

After the assembly of diagonals 50.1 and 50.2, for the purpose of a configuration of a frame hooking device 50, an additional frame 20.4 is supported or engaged in or on the free ends 67 of the diagonals

50.1 and 50.2, so that he leans there with his step 17.5. In this transition position 40, the additional frame 20.4 is therefore hung in a vertical or perpendicular position at the free engagement ends 67 of diagonals 50.1 and 50.2 and is supported only by these diagonals 50.1 and 50.2.

A frame 20.3 is fixed or fitted on the frame 120.2 and specifically so that the vertical planes configured by the frame 120.2 and the frame 20.3 coincide. On the 17.1 highest step of the frame

20.3 a handrail element 18.2 is fixed so that it can be disengaged again by means of an interlocking nail 55 provided at one end and rotatably with respect to the frame 20.3. Next, the assembler keeps this railing element 18.2 in the area of the other end still free and rotates the additional frame 20.4 around the horizontal rotation axis 57 in the direction of the arrow 86 so much so that it can fix the railing element 18.2, respectively the locking nail 55 provided at this free end, on the step 17.1 higher of the frame 20.4, after which it fixes the railing element 18.2 correspondingly on the step 17.1 of the frame 20.4 so that it can be disengaged again and from rotating way with respect to the frame 20.4.

Next, the assembler fixes an additional equal railing element 18.1 with an interlocking nail provided by one end again on the step 17.1 higher of the frame 20.3 and at the other end with an additional interlocking nail 55 on the step 17.1 more high of frame 20.4 which is in a transition position and inclined 40.1. The mounting position achieved is shown in Figure 27. Next, the assembler 52 moves the frame 20.4, together with the railing elements 18.1 and 18.2 fixed therein and also in the frame 20.3, already positioned distantly and oppositely , rotatably to these two frames 20.4 and 20.3, upwards to a position above the transition position 40 and also above the transition position 40.1, so that the frame 20.4 with its lower step 17.8 can be driven up to the free ends of diagonals 50.1 and 50.2 ahead, up to a position, from which then the frame 20.4 can be fixed or placed on the lower frame 120.1 (figure 29). Next, the upper or additional frame 20.4 is fixed on the lower frame 120.1, or placed on it, after which the first four frames 120.1 are constructed according to the invention according to the invention of a four-frame construction unit. , 120.2, 20.3 and 20.4, as illustrated in Figure 30.

Next, the assembler removes the two diagonals 50.1 and 50.2, which have previously served as a frame hitch device 50 for the additional frame 20.4, after which it incorporates these two elongated scaffolding elements, now in its function as diagonals 50.1 and 50.2, again on the scaffolding on wheels 1.2 to be built or recessed there, as this is illustrated for example in Figure 30. In this respect the diagonal is fixed

50.1 with its locking nail 55 provided at one end on the lower step 17.4 of the first frame 120.1 and is fixed with its locking nail 55 provided at its other end on the step 17.5 of the third frame 20.3. The other diagonal 50.2 is fixed with one of its interlocking nails 55 on the lower step 17.4 of the second frame

120.2 and is fixed with its other locking nail 55 on step 17.5 of the fourth or additional frame 20.4. According to this, the two diagonals 50.1 and 50.2 lower in cross or in a criss-cross manner are also built to build the scaffold on wheels 1.2.

Next, the assembler 52 on the lower scaffolding platform 130.1 assembles an additional or higher or second scaffold platform 30.2, in which case it is a step scaffold platform with a passage opening 31. The assembly of this upper or second scaffolding platform 30.2 is carried out in this respect at a distance 53 below the highest rail elements 18.1 and 18.2, so that these form an advanced railing, so that they serve as protection elements of back or hip to protect a person who is on the platform of scaffolding 30.2 superior or second against falls.

The additional construction of the scaffolding on wheels 1.2 is configured the same as the construction of the scaffolding on wheels 1.1 according to figures 9 to 14, this additional construction of the scaffolding on wheels 1.2 can take place also in figures 32 to 37 also corresponding to the sequence of construction that results from this.

A disassembly according to the invention of the scaffolding on wheels 1.2 shown in Fig. 37, constructed in a finished manner with three floors 15.1 to 15.3 or plants is carried out in the same manner as the disassembly of the scaffolding on wheels 1.1, specifically as described above and illustrated there by means of figures 15 to 19. The corresponding disassembly or the disassembly sequence in case of disassembly of the scaffolding on wheels 1.2 is illustrated in figures 37 to 42.

Also the subsequent disassembly of the scaffolding on wheels 1.2 is carried out in a similar manner as the additional disassembly of the scaffolding on wheels 1.1, started from figure 20. If it is split for further disassembly of the scaffolding on wheels 1.2 of the disassembly situation shown in figure 42, then the disassembly of the second frame 30.2 now higher is carried out as follows, and specifically by an assembler that is located on the lower scaffolding platform 130.1, especially for that assembler that was previously still on the platform of 30.2 higher scaffolding and has passed from there through its passage opening 31 to the lower 130.1 scaffolding platform.

After the exit of the scaffolding platform 30.2, the assembler 52 takes out the two remaining diagonals 50.1 and 50.2 and then incorporates these, as shown in figure 43, again as a frame hitch device 50 for a frame which is still to be removed, in this case for frame 20.4 "'. For this purpose, the two diagonals 50.1 and 50.2 respectively are fixed with an interlocking nail 55 provided at its end on or on the lower step 17.4 of frame 120.2" ', so that these ends then act as fixing ends

68. The diagonals 50.1 and 50.2 thus fixed are incorporated so that they rest in the area of their other ends on the step 17.1 higher of the frame 120.1 "'which is facing in a distance, extending their free ends outwardly through of this frame 120.1 "'out of it and configuring free hook ends 67 to engage the frame 20.4"' to be removed. After mounting the diagonals 50.1 and 50.2 as a frame hooking device 50, the assembler 52 disengages the frame 20.4 "'of frame 120.1 that is below and moves it along with railing elements 18.1 and 18.2 fixed on its step 17.1 higher down to a transitional position and inclined 40.1, so that step 17.5 of the frame 20.4 "'rests on the coupling ends 67 of diagonals 50.1 and 50.2. The disassembly situation achieved is then illustrated in Figure 43.

Starting from this, the assembler 52 disengages the two highest railing elements 18.1 and 18.2 of the frame 20.4 "'and then releases it so that then the frame 20.4"' can rotate conditionally by the force of gravity to the position of transition 40 '"vertical or perpendicular shown in Figure 44, in which the frame 20.4"' hangs on the frame engagement device 50 formed with the two diagonals 50.1 and 50.2 supported only by it.

Next, the assembler 52 rotates the two railing elements 18.1 and 18.2 in the direction of the arrow 58 in or on the frame 20.3 "'to a vertical position, which is illustrated in Figure 45, in which therefore the two elements of railings 18.1 and 18.2 through their interlocking nails 55 hang on the step 17.1 higher of the frame 20.3 "'vertically down. To disengage the two railing elements 18.1 and 18.2, an elongated scaffold element is used again, preferably a bar at knee height 18 previously incorporated in the scaffold on wheels 1.2, in this case the bar at the knee height. 18.3, with the process of dismantling or unhooking the same, as described above in relation to the disassembly of the scaffold on wheels 1.1.

After unhooking the two railing elements 18.1 and 18.2 of the frame 20.3 "', this frame 20.3"' is also disassembled, therefore it is disengaged and removed from the frame 120.2 "'. The pieces that remain then of the scaffold on wheels 1.2 are represented. in figure 46. Then only the two short frames 120.1 "'and 120.2"' of their respective mobile beam 2.2 or 2.1 must be disengaged and the scaffolding platform removed or disengaged

130.1 lower than the two auxiliary steps 11. Then the remaining unit of the two movable beams 2.1 and 2.2 and the four clamping rollers fixed therein can also be removed as well as the frame bar

or the base tube 9.

The assembly and disassembly of the additional embodiment example shown in Figure 51 of a scaffold on wheels 1.3 is carried out essentially the same as the assembly and disassembly of the scaffold on wheels 1.2, with the difference that two scaffolding platforms are mounted respectively. next to each other in the correspondingly wider frame 220 per floor or floor 15.1 to 15.4, which are also disassembled again correspondingly to this in case of disassembly. In this respect it is sufficient when from the second floor 15.2 to the highest floor 15.4 only one of the two scaffolding platforms 30.2, 30.3, 30.4 is configured as a scaffolding platform with a passage opening 31, while all the other scaffolding platforms 230.1.1, 230.1.2; 230.2, 230.3, 230.4 can be configured as complete scaffolding platforms, therefore without passage opening, as shown by way of example in Figure 51.

An alternative embodiment of a frame hitch device 150 is shown in Figures 47 to 50 together with some relevant mounting positions in case of mounting a scaffold on wheels. In the case of this frame hitching device 150, it is a separate additional piece 70, which is not embedded or not embedded in the scaffold on wheels to be constructed or finished with other scaffolding parts, especially support . This additional piece 70 can be configured as a U-profile 72, which can be formed or manufactured with a base body 73 in the form of a plate and two support branches 74.1 and 74.2 extending outwardly from it in equal directions. Preferably, the support branches 74.1 and 74.2 are folded or folded or folded or folded from the base body 73. Regardless of this, the support branches 74.1 and 74.2 can be manufactured in one piece with the base body 73.

The support branches 74.1 and 74.2 are approximately perpendicular to the base body 73 and have, respectively, at their upper ends in mounting position a hook for frames 71.1, 71.2. The hooks of frames 71.1 and 71.2 are arranged at a horizontal distance 75 from each other. Hooks 71.2 and 71.1 delimit holes 89.2 or 89.1, which are determined respectively to accommodate a step 17.1, 17.2 of a frame 20.4 to be engaged there in a transition position 40, 40.1, to be mounted or to be mounted dismount On the rear side of the additional piece 70, a hooking device 76 is configured, preferably manufactured in one piece with the base body 73, which in this case is configured with four hooks 76.1 to 76.4. In this regard, two upper hooks 76.1 and 76.2 are provided for engaging the additional piece 70 or the frame hooking device 150 on an upper step 17.1, and two lower hooks 76.3 and 76.4 are provided spaced apart, which allow an additional hitch or support of the additional piece 70 or of the frame hooking device 150 on a lower step 17.2 of the same frame 20. The hooks 76.1 to 76.4 are formed in the exemplary embodiment shown from the base body 73 and are manufactured by folding or bending with respect to the base body 73 in a position perpendicular to it.

The distances of the hooks 76.1 and 76.2 or their rung support surfaces from the lower hooks 76.3 and 76.4 or from their rung support surfaces are selected so large that they correspond to the distance of two rungs 17, preferably of two steps 17.1 and 17.2 immediately adjacent. However, it is understood that a frame engaging element configured as an additional part may also have only one or only two hooks for engaging in a frame, preferably in a step 17 of a frame 20, 120, 220.

For an assembly according to the invention of a scaffold on wheels, the frame hooking device 150 can be hooked or the additional piece 70 can be hooked on the steps 17.1 and 17.2 of a mounted frame 20, 20.1, after which in the holes 89.1 and 89.2 delimited by the hooks of frames 71.1 and 71.2, a step 17 can be hooked, for example the step 17.4 of a frame 20, 20.4 comprising, for example, eight steps, as shown for example in Figure 48.

To allow a vertical or perpendicular downward hitch of a frame 20, 20.4 therein engaged in a corresponding transition position, the support branches 74.1 and 74.2 are narrowed in the direction of their hooks 71.1 and 71.2 outward, that is in the been mounted down. Because of this, a frame 20, 20.4 can be hooked there, locked in its transition position 40 vertically or perpendicularly and securely, preferably supported only by the frame engagement device 150 or by the additional piece 70.

Starting from the transition position 40 shown in FIG. 48, the frame 20, 20.4 can be rotated therein engaged with respect to the frame engaging device 150 and also with respect to the lower frame 20, 20.1 which supports it around an axis of rotation 57 which coincides with the longitudinal axis of the step 17.4 of the frame 20.4 to a transition and inclined position 40.1, as shown by way of example in figure 49. In this position the two railing elements 18.1 and 18.2 can be coupled in the 17.1 higher step of the additional 20.4 frame. After removing the frame 20.4 from the frame engaging device 150 and raising the frame 20.4 together with the railing elements 18.1 and 18.2 fixed thereto up to a position, from which the frame 20.4 can be fixed on the frame 20.1 , preferably it can be fitted, the frame 20.4 is fixed, as shown in figure 48, on the frame 20.1 or placed on it. Then the mounting position illustrated in the partial representation according to Figure 50 is obtained.

The additional piece 70 which acts as a frame hooking device 150 can then be disengaged and hooked again in another position to build or disassemble one or the scaffold on wheels, to also allow in this additional position the construction of an advanced railing or an assembly according to the invention of a scaffold on wheels or a disassembly according to the invention of a scaffold on wheels.
