Description

Technical area

The invention relates to a stage system that is in the field of construction is usable.

When erecting structures, scaffolding is made of numerous stage elements can be constructed for various work required. For example, must from scaffoldings the reinforcements are attached. Further are usually required for concreting Shuttering elements furnished by scaffolding. Even while of concreting workers are on scaffolding, to those containers or bodies that make up the Concrete flows between the formwork to handle. Also Works on the facade are carried out from scaffolding. Finally, in climbing formwork systems are usually Mounted on climbing consoles scaffolds by these scaffolding from all the above activities in the Regarding the each above the climbing console new to To carry out concreting building section.

State of the art

In the prior art a variety of scaffolds are known, the adapted to each of the above-mentioned activities are. For example, there are facade scaffolding in which vertical carriers in a particular grid such be erected that between each four, in the Top view of a rectangle forming vehicle a stage covering can be hung up. From EP 0 195 806 B1 it is here especially known to provide an entire scaffolding module, at the stage coverings are attached to the carriers foldable, so that the arranged on one side of the work coverings Carrier on the arranged on the other side carrier can be worked out so that the scaffolding module in total is relatively small collapsible.

In WO 90/14479 a framework is disclosed which also to arranged on all four corners of rectangular work platforms Carrier, wherein the working platforms either hinged or foldable on the straps that are in the be located on the back of the building.

Such scaffolding is for certain work on the building quite usable. In particular, for reinforcement can of such scaffolds are made, and those Beams, which are arranged to the building, disturb can. However, before the formwork elements are used, it is necessary that in the previously described Way to dismantle scaffolding. Setting up the Formwork elements is not possible, if the scaffolding stay put, because the formwork elements exactly in the Must be handled by scaffolding, and here in particular from the arranged to the building Carriers is taken.

For that reason, it also offers no alternative To build facade scaffolding on working platforms, which are attached to the already established part of the building are anchored. Next The disadvantages indicated above are the problem that the facade scaffolding on the work platform tensile strength would have to be anchored, what for the known stages no connections are available. Finally, the Facade scaffolding for this purpose also not suitable, because to carry out subsequent work often material must be stored on the stages, what with the Facade scaffolding only on the top stage is possible.

These disadvantages are also at the subject of DE 197 18 650 A1 not resolved, in which by additional parts a possibility is created, common facade scaffolding frames to a fastened to a building wall Remove scaffold frame. This will only be a substitute created for separate console scaffolding.

In the field of climbing formwork, it is known Attach work platforms to formwork elements, creating a Possibility is created, for example during the Concrete to work on these work platforms. Because the Work platforms fixed above the formwork elements However, they are useless for the reinforcement, so that this own auxiliary scaffolding are required. consequently It also applies to these solutions that they only for certain activities are suitable, and further scaffolding for the other activities are required.

GB 2 180 583 A describes the preamble of claim 1 and in particular a single scaffolding with a stage suitable for Gardening and housework is adjusted and next to one Carrying structure a single, foldable stage cover pointing towards a hedge or a building projects. The single scaffold can be supported on a building, to carry out work. Because of this support and because of the property as a single device is a such scaffolding for use as scaffolding, especially for the execution of formwork work not suitable.

This applies equally to the subject matter of the US 2,398,604 corresponding to the preamble of claim 2, and in which a plurality of stator elements are provided which are supported on an already created building wall, wherein on the supports boards can be placed to form a stage are. Also, such a system is in construction, in which Shuttering elements for creating new walls need to be set up, not usable.

Finally, from DE 89 09 026 U1 a folding platform Known to have a frame and a hinged to it has attached stage covering. By means of the frame is the folding platform can be hung on building anchors. With this stage Consequently, no part of the building can be built up the same level as the stage is to be concreted. Furthermore, any work required on the building will be required through the frame attached directly to the building with special needs.

Presentation of the invention

The invention is based on the object, a stage system with multiple stage elements to create that flexible can be used and that is suitable for the implementation of numerous different activities within the framework of the Creation of a building is suitable.

The solution to this problem is provided by the features of Patent claim 1 or 2.

Accordingly, a stage system is provided according to the invention, which consists of several similar stage elements, the in a first embodiment, at least one carrier exhibit. The carrier (s) essentially serve the stage covering and optionally attachable, further Facilities such as e.g. Rear guards, too wear. In a second embodiment that is Stage element designed such that there is no carrier has, but a support member, by means of which the Stage element can be fastened to a carrier. Both Embodiments according to the invention have in common that free from the carrier or the carrying element in the attached state projecting a stage covering that folds out is trained.

The measure according to which the stage covering on the carrier or the Carrying element in the attached state cantilevered is formed, offers the substantial advantage that at the directed to the building side no disturbing vertical beams available. Rather, it is directed to the building Area in the horizontal direction continuously clear, leaving from the stage covering without hindrance the reinforcement work and the handling of concreting facilities can take place.

Furthermore, the stage element according to the invention is characterized characterized in that the stage cover is designed to be foldable, what about the stage cover overall and / or one Part of the stage cover can be provided. This will the stage element also for other activities, as the above already mentioned, can be used. In particular, it is possible to fold back the stage covering, and in the area in which the now folded back stage coverings were, the Handling and setting up shuttering elements. That through formed several stage elements according to the invention Stage system does not need to be offset for this purpose. By the Folding back the stage covers will give room for handling and device of the formwork elements created.

Finally, the foldable training allows the Stage coverings too, that with a scaffolding that through several Stage elements according to the invention is constructed, material not only on the top surface, but after that Fold back the topping also on the underlying stage coverings can be stored. Overall, therefore, are of a scaffold that through several Stage elements according to the invention is constructed, all in Framework of the construction of the works, like rebar, shells, concreting, moving Prefabricated parts and subsequent façade work possible, without the scaffold replaced by another scaffold or must be added, or the framework must be moved.

Preferred developments are in the further claims described.

It offers for the foldable training of the stage element certain advantages when the stage covering is overall hinged is attached to the support or the support element. These Measure is particularly for example in the case advantageous that on a below the top Stage covers arranged stage covering material filed shall be. To hamper this process as little as possible, the stage covering in this embodiment may be total be folded back.

Alternatively, or as currently preferred, in addition to The feature described above, it is advantageous to the Stage covering not only in the area of its attachment to the Carrier or the support element, but at one point along its extension in the direction of the building foldable too shape. This makes it possible, only the foremost Area of the stage covering either slightly or too fold back completely, so that unfolded on the remaining area of the stage covering standing possible is, and workers from there, for example, the Setting up the formwork can perform. Especially after folding back the foremost area of the Stage covers a collision and interference between this Area and the formwork elements to be established prevented. Overall, as mentioned, the preferred Stage covering foldable to form all the to realize the aforementioned advantages.

From a safety point of view, it is preferred that on the Stage element as an integral part of a Attachment arranged at the back of the building Guard is provided. For this protection device It has proven to be advantageous to remove them form so that after removing the guard also a supply of material not only from above, but also from the back of the building, to any one Level, is possible.

Since the lateral dimensions of the invention Stage element not to the dimensions of a building should be adapted, but rather uniformly is to be designed, is in a special Embodiment provided a stage element, whose Stage covering and / or optionally protective device has at least one telescoping compensation element, so that a gap to adjacent stage coverings and Protective devices can be closed, and that emerging stage system has a flexible width.

Although the use of a single stage element is conceivable, is of course preferred from several Stage elements to build a complete stage system. In in the event that stage elements are used instead a carrier at least have a support member consists the stage system next to the several stage elements at least one carrier.

In this case, it is preferable for the carrier to have more than one Stage elements, preferably one above the other, are attachable, so that results in a multi-storey scaffolding.

For the above-described stage system with at least a carrier or that embodiment of the Stage element according to the invention, comprising a support, is preferred for the carrier, that this at its lower End is designed such that the stage system or the Stage element can be set up on a level floor. By This measure ensures that the inventive Stage system is usable in the same way as conventional facade scaffolding.

In addition, it is preferred that the carrier at its lower End is additionally designed to be on a console to be mounted. This will increase the compatibility of the inventive stage system or stage element with Climbing brackets guaranteed, on which, preferably also multi-storey, the stage system according to the invention attachable is. Thus, even with climbing formwork systems all required activities, such as Reinforcing, setting up the Formwork, concreting and subsequent work of one and the same framework, its location is not must be changed.

For stability reasons and for usability as Facade scaffolding to realize, it is preferred that the Stage system or the stage element on a building can be anchored.

To the mentioned usability for all required Activities, in particular the setting up of the Shuttering elements to achieve, it is further preferred that the stage system according to the invention or stage element such is designed that a formwork element anchored thereto is.

Detailed description of preferred embodiments of invention

In Fig. 1 is in an unfolded state and a the Attachment state corresponding orientation from the side Stage element 14 according to the invention in a first Embodiment shown. This indicates as part of the Stage element 14 no carrier on, but rather an im Attachment on the side facing away from the building arranged support member 18, with which the stage element a carrier is attachable, as hereinafter with reference is explained in more detail on the Fig. 3. In the shown Case, the stage element 14 at both (from the front or Rear side of the considered) side edge areas shown support member 18 (see Fig .. 3).

From the support member 18 extends in the attached State cantilevering in the direction of (not shown) Building a stage covering 22, which points to the support element is supported by a strut 36. According to the invention Stage cover 22 hinged formed, which in the shown Embodiment is realized in two forms. To the one is located at the transition between stage covering 22nd and support member 18 a first hinged hinge 38, by means of of which the stage covering 22 is shown in FIG. 2, folded position can be brought. As below is explained in more detail, this function in the Use of the stage element 14 together with other, arranged above the stage elements are used to Stage covering 22 of the top stage element 14 completely Fold back to the material from above lay down underlying stage coverings or the reinforcement contribute.

As in the course of the extension of the stage covering 22 in Direction of the building is recognizable, the stage covering points 22 of the embodiment shown in Fig. 1 another Folding hinge 40 between the foremost region 42 and a rear portion 44 of the stage cover 22. through of the hinge 40, the front portion 42 may be all or partially folded back towards the rear area 44 so that in the area where the foremost Area 42 is in the unfolded state, without mutual interference a shuttering element can be arranged can. This is the result of a stage system that through a plurality of the illustrated stage elements 14 is formed, both the reinforcement, for which the fully unfolded Stage covering 22 is used, as well as the subsequent Setting up the formwork elements possible, for which the foremost region 42 at least slightly upwards or is completely folded back on the rear portion 44. In Fig. 1, it can finally be seen that of the Carrying element 18 from up a protective device 24, usually in the form of a grid, extending to the Secure the building rear-facing area.

As is apparent from Fig. 2, the inventive Stage element 14 advantageously in a small space fold. For this purpose, the stage cover 22 is a total order the hinge 38 upwards, in the direction of the guardrail 24 folded, the strut 36 released from the support member and will work in the same orientation. In the in Fig. 2 illustrated, folded state can be several stage elements on each other with a small footprint store by putting in front of the presentation Of Fig. 2 rotated by 90 °, brought flat alignment become.

In Fig. 3 is shown how three of the in Figs. 1 and 2 shown stage elements 14 to a stage system 10th be combined. For this purpose, the three stage elements 14 one above the other by means of their respective support elements 18 two columnar supports 20 attached and by bolts or fixed by quick connection. The carriers 20 have a grid of openings or, for example, projections on, so that the stage elements each at a suitable height can be mounted. As is apparent from Fig. 3 in combination with the representation of Fig. 1 results, the collar Stage elements 22 each forward, so according to the Representation of Fig. 3 out of the plane, out, so that in the area facing the building no other support elements or supports are located, and in this Area can be worked freely. Of course you can the stage system 10 shown in Fig. 3 readily with additional, laterally or above arranged sections of the stage system can be combined to a total of one multi-storey, large facade scaffolding or scaffolding form a climbing system. In particular, the shown carrier 20 with further, arranged above Carriers for example via a flange or Plug connection are coupled.

This applies in the same way for in Fig. 4 in a Side view illustrated second embodiment of according to the invention stage element 12. This corresponds with respect to the case foldable in the case shown twice Training the stage cover 22 and its support by a strut 36 of the shown in Figs. 1 and 2 Embodiment. Instead of the support member 18 of the first Embodiment, the stage cover 22 but with a Carrier 16 connected. In the carrier 16, of which as in the Stage system according to FIG. 3 at both lateral edges one each is provided (see Fig. 6), it is essentially vertically aligned in the mounting state Struts, by suitable fasteners 46 at the similarly designed carriers 16 more Stage elements are attachable, so that a multi-storey scaffolding, each with cantilevered Stage coverings 22 results. Also in the illustrated Embodiment of the second embodiment is in the Rear area a guard 24 attached.

As is apparent from Fig. 5, the second is also Embodiment of the stage element 12 according to the invention by means of the hinge 38, via which the stage covering 22 a total of hinged on the support 16 is mounted in a flat shape collapsible. This can also be done a plurality of stage elements 12 of the second embodiment be stored flat stacked on a small space. This results from the first described above Embodiment of the further advantage that no additional Carrier must be stored, as these in the form of the carrier 16th are provided as part of the stage element 12.

In Fig. 6 is corresponding to the illustration of Fig. 3 a Example of a stage system 10 shown that consists of three stacked stage elements 12 of the second Embodiment exists. As is apparent from Fig. 6, the Carrier 16 each provided on both side edges. It was mentions that the beams 16 of the second embodiment in FIG their lower area can be designed to be not only with the carriers 16 other stage elements connectable, but also on level ground installable and on the console of a climbing formwork system are attachable, as will be explained in more detail below. Of course, this applies equally to the case of the first embodiment provided carrier 20, where preferably several stage elements 14 are attachable. It was still mentioned that for the carrier 16 currently a height of 2 m is preferred, so that thereby a corresponding Stage system can be set up, its stage cover 22nd each spaced apart by 2 m in height.

In Fig. 7 is a side view of the use of Stage system 10 according to the invention shown in the reinforcement. In the situation shown, the inner formwork 48 is already placed and supported against the ground 30. For the Stage system 10 can be seen that it is also on the level bottom 30 is set up. It should be mentioned that in the Fig. 7 to 9, a stage system consisting of several Stage elements of the second embodiment is shown, and that of course also a stage system consisting of Stage elements of the first embodiment is usable.

As can be seen in FIG. 7, the uppermost stage covering 22 folded back, what for attaching the reinforcements 50 was beneficial. In the situation shown in Fig. 7 are now from the two lower stage coverings 22 the reinforcements were carried out. It is advantageous each completely unfold the stage coverings 22 so that the workforce as close as possible to the reinforcements 50 can approach. The cantilevered training of the Stage covers 22 offers the advantage that in the area of Reinforcement no disturbing beams or columns available.

From Fig. 8, the advantageous usability of new stage system 10 also for the after reinforcement required work. For one thing, as for the two lower stage covers can be seen, the respective front Area 42 advantageously so partially folded back that space for a formwork element 34th is created. This is also each suitable Attachment and adjustment devices 52 to the respective Carriers 16 of the stage elements connected. Thus, how As is apparent from Fig. 8, the stage system 10 according to the invention also for setting up and fixing the formwork elements 34th usable. In addition, as in the upper part of the Fig. 8 can be seen, the concreting of the Stage system 10 according to the invention can be carried out, without this being offset or by another stage system or scaffolding must be replaced. The cantilevered Training the stage covers 22 provides in this context the advantage that the concreting work is not by carriers or supports are disturbed. This advantage is particular realized compared to the conventional facade scaffolding, the can replace the stage system of the invention. Of the For the sake of completeness it should be mentioned that in a similar way, as shown in Fig. 8, the concreting of Ceilings are possible by placing inside the building instead the inner formwork 48 shown in Fig. 7 and 8 a Slab formwork system is placed on the following also from the top stage covering in FIG. 8 is concreted. Furthermore, this is when concreting on the Ceiling personnel through the top stage cover protected from falling.

In Fig. 9 is finally shown how the inventive stage system 10 in an advantageous manner a climbing formwork system can be combined, the one Console 32, to which the stage formwork system 10th with its lowest support 16 is mountable. For this purpose is the stage system 10 usually largely assembled state on the means of Climbing equipment attached to the exterior of the building Consoles 32 lifted. Hereinafter, the stage system 10 is as Part of the climbing formwork system again for all of can be used for required work. First, in the Fig. 7 corresponding situation of the complete unfolded stage coverings 22 performed from the reinforcement become. As can be seen in Fig. 9, below can at partially folded back stage coverings 22 the Formwork elements 34 of the outer formwork introduced and to the Supports 16 of the stage system 10 are fixed. After all can in particular from the top stage covering 10 of the Concreting be performed. If the outside formwork too it must be removed at any time in turn, the stage coverings 22 at least partially fold back, leaving enough room for handling the Shuttering elements 34 is available. It is still mentions that the complete scaffolding created by the Stage system 10 according to the invention is formed, together with the attached formwork elements 34, the console 32nd and below suspended suspended platform 54 by means of a Cranes can be implemented if this instead of a Klettersystems is used.

Furthermore, the stage cover 22 each have an integrated Have got through, so in a scaffold that through numerous side and superimposed stage elements 12 or 14 is formed by combination with corresponding ladder elements a complete passage ensure.

In Fig. 10 is an alternative in a side view Embodiment of the stage system 10 according to the invention shown. This embodiment is consistent with the embodiment Figs. 4 to 6 insofar as the single Stage element 12 has a carrier 16, on which a free cantilevered stage cover 22 is attached hinged. The Embodiment of FIG. 10, however, differs from that of FIG. 4 to 6 in that the stage covering 22 in the region of the upper end of the individual carrier 16 of the Stage element 12 is attached. This results in the Advantage that the solid support 16 of the uppermost Stage element (see Fig. 6), which in itself from static Reasons are no longer necessary to be saved can. As is apparent from Fig. 10, the uppermost ends Stage element 12 in the region of the attachment point of the uppermost Decking 22, and above the level extends in Contrary to the embodiment of FIG. 6, no carrier 16 more. To meet the safety requirements, is in the upper end of the two arranged parallel to each other top carrier 16 only a comparatively light Plug rail 24 inserted as a protective device.

As is apparent from the lower portion of Fig. 10 extends in this embodiment of the invention Stage system 10, the respective protection device 24, so the Railing, the single stage element 14 from the lower End of the carrier 16 up to the required height. Of the Stage covering for the lowest level (apart from the underneath suspended platforms 54) is replaced by the Stage covering the console 32 formed in which the with Dashed lines indicated traverse is formed. With regard to the attachment of the carrier 16 is still noted that these, as can be seen from the figure is, in the case shown on the console 32 and at other applications on a suitable floor support supplementally supported by support struts 56. hereby the individual carriers 16 can be dimensioned somewhat lighter which increases their profitability.

Another difference between the embodiment according to Fig. 10 and the embodiment shown in Figs. 4 to 6 is that the stage covering 22 total down can be folded down. As is apparent from Figs. 2 and 5, is at the embodiments described so far an up-flaps intended. Since the stage cover 22 at the Embodiment of FIG. 10 in the region of the upper Carrier end of the individual carrier 16 is a Fold down advantageous because this way the Dimensions of the individual prefabricated and folded stage element 12 within reasonable limits can be kept. In detail, the stage cover 22 for transporting and storing down in such a way, that it rests on the protective device 24. In Consistent with those described above Embodiments is the foremost portion 42 of FIG single stage covering 22 also in the embodiment of Fig. 10 can be folded upwards.

With regard to the console 32 should be mentioned that the Area at the back of the building between the support struts 56 can be used advantageously to material to take off and to the stage covering from the back of the building ago supply. For this purpose, for example, to the am farthest edge of the console 32 away from the building as well as to the building in the area of the respective Support struts 56 may be provided extending a railing, and the railing 24 shown in Fig. 10 at the lowest Stage element 12 omitted. In a similar way it is of course also on all other stage elements 12th of the shown stage system possible, at the back of the building own consoles for storing and feeding material to attach, which is not shown in the figures.

Finally, it should also be mentioned that at the bottom of the Console 32 mounted suspended platforms 54 from prefabricated and easily assembled stage elements, whose Stage cover is also hinged. Finally, in the area of suspended platforms in Advantageously bridging support, for example for Bridging building openings, used as they are are known for conventional folding stages.
