Description

Cladding device for scaffolding

The present invention relates to a cladding device for scaffolding with flat cladding elements, which are usually arranged on the outside or inside of the scaffolding and are used in particular to protect against the passage of liquids and dust as well as to protect against the passage of solid bodies and to provide heat and sound insulation, with connecting devices, which each have a first connection unit for connection to posts or bars of the scaffolding and a second connection unit for connecting the cladding elements, wherein the cladding elements have an edge profile unit at least in the upper and lower edge area.

When using scaffolding, particularly for larger buildings, but above all in adverse weather conditions, when there is a lot of dust, for example as a result of sandblasting work, and in the area of streets and squares that are heavily used by pedestrians and vehicles, it is often necessary to cover the entire outside surface of the scaffolding with a covering so that, on the one hand, no objects or people can fall out of the working area of the scaffolding and, on the other hand, liquid, dust or other materials do not escape into the outside area of the scaffolding and endanger people or vehicles in the area around the scaffolding. It can also be useful to have suitable clothing to protect the people working in adverse weather conditions.

STATE OF THE ART

It is known, depending on the requirements, to use either mesh with wire mesh or foils and/or tarpaulins - with fabric-reinforced foils - for covering purposes, which cover larger areas of the scaffolding depending on the handling options and overlap each other at the joint areas or are equipped with other fastening and mutual sealing means. However, spreading out and fastening the tarpaulins requires considerable manual work and tarpaulins also tend to flap violently, especially in wind and storms. It is only with disproportionate effort that such tarpaulins can be attached to the scaffolding in many places. This gave rise to a need for rigid scaffolding cladding, which is disclosed in DE 41 25 664 Al. In such cladding for scaffolding, cladding elements are attached to the horizontal longitudinal tube of a scaffold, which contains, for example, posts and diagonal bars, using hooks and securing elements. These are interchangeably attached to the frames of the cladding elements. The cladding elements are fitted with corrugated metal panels and, if necessary, side seals or overlaps. Piping grooves for tarpaulins and aprons can also be provided.

DESCRIPTION OF THE INVENTION

The invention is based on the technical problem or task 0, starting from the above-mentioned prior art, of creating a scaffold cladding made of rigid cladding elements that can be quickly assembled and disassembled in a simple manner and in which connecting devices can be used that can be manufactured economically 35

can be used, ensure problem-free connection to standard scaffolding components and enable reliable and easy-to-use fastening of the cladding elements.

The cladding device for scaffolding according to the invention is given by the features of independent claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

The cladding device according to the invention is accordingly characterized in that the second connection unit has at least one cantilevered rod element, the free end of which points upwards and/or downwards, the edge profile units have recesses open at least from below or above, wherein the free end of the rod element of the second connection unit can be brought into engagement with a recess of the edge profile unit of the cladding element.

Preferably, the first connection unit is designed as a pipe coupling unit or as a wedge head unit with a clamping wedge, so that a problem-free connection to the well-known Layher Blitz scaffolding or Layher Allround scaffolding is possible.

It is particularly advantageous in terms of simple assembly to provide the recesses throughout, whereby the recesses are preferably designed as elongated holes.

For practical assembly work, it has proven to be advantageous to arrange the recesses at the side edge area of the edge profile units.

A particularly preferred embodiment is characterized in that the length of the free end of the rod element is essentially as large as the height of two

edge profile units arranged on top of each other with cladding elements arranged one above the other. During assembly, the procedure is that first a cladding element is hooked onto the rod element with its upper edge profile unit and then a cladding element arranged above it with its lower edge profile unit with recess engages with the free end of the rod element.

A particularly economical manufacturing method can be implemented by designing the rod element as a round profile element, whereby a curved round profile element structure is preferably used. In addition to being economical to manufacture, such a design ensures sufficiently high strength and rigidity values to implement a permanently reliable load-bearing function for the cladding elements. The cladding elements can be dismantled in a simple manner by pulling them upwards.

A particularly advantageous, easy-to-assemble design variant is characterized by the fact that the rod element/pulling rod elements have a curved profile structure. A rod element structure has proven to be particularly advantageous, which is characterized by the fact that the two rod elements are formed by a curved round profile structure, which, when viewed from above, has a substantially U-shaped structure, with the web of the U-shaped structure being attached to the first connection unit, and, when viewed from the side, has a substantially L-shaped structure with an upwardly pointing free leg that forms the free end of the rod elements.

When using cladding devices on the construction site, certain problem areas always arise, such as corner areas, fitting or compensation fields, which cannot be covered with the prefabricated cladding elements. Since then, the imagination of the scaffolding builder on site has been required to reliably cover these problem areas as well.

The present invention is further based on the task or technical problem of offering a solution to problems in the edge area of connected cladding elements, be it for compensation fields or for corner areas, which can be produced economically, enables adaptation to the individual problem area dimensions, ensures a permanently reliable sealing function and can be easily assembled and disassembled on site.

The end profile device according to the invention is given by the features of independent claim 14. Advantageous embodiments and further developments are the subject of the dependent claims that relate directly or indirectly to claim 14.

The end profile device according to the invention is characterized accordingly in that the profile device has a thin-walled, open profile unit with a longitudinally continuous recess and a solid profile unit is inserted into the recess, which consists of a material that allows the connection of nails, screws or similar fastening means. Preferably, the solid profile unit is designed as a square profile unit, whereby in a particularly advantageous embodiment wood is used as the material for the solid profile unit. During assembly on site, this end-35

profile device is easily attached to the respective front edge of the cladding elements in the problem area in question and then a piece of metal - for example a sheet of metal - that corresponds to the respective dimensions of the problem area can be easily nailed on.

A particularly preferred embodiment is characterized in that a piping opening is formed in the profile device so that, if required, a tarpaulin with piping can be easily connected to the end profile device.

In order to reliably ensure tightness in this edge area as well, an advantageous design is characterized by the fact that the end profile device has a recess in which a protruding sealing profile is anchored.

According to a preferred embodiment, a simple connection to the cladding elements is ensured in that the profile unit essentially has a square contour, the recess and the piping opening are formed on opposite outer sides in the wall of the profile unit, a projection unit with a continuous recess is formed on the outer side opposite the recess, whereby a particularly preferred further development is characterized in that a nut, in particular a rivet nut, is present in the recess.

A particularly advantageous design in terms of economic production is characterized by the fact that the thin-walled profile unit is made as an extruded profile, 35

WAYS TO CARRY OUT THE INVENTION

Fig. 1 shows a schematic of a scaffold 12, which is designed in terms of its supporting structure as a well-known so-called Layher all-round scaffold system. Vertical posts 26 are used here, which have perforated disks 48 at a predetermined distance in the longitudinal direction, to which horizontal supporting elements 49, crossbars 28 and similar elements can be connected diagonally using the well-known and proven wedge head connection technology.

In the middle area of the scaffold 12 according to Fig. 1, a detail of the arrangement of cladding elements 14 of a cladding device 10 is shown. The cladding elements 40 are connected to the scaffold via connecting devices not shown in detail in Fig. 1, which are connected to the scaffold on the one hand and connect the cladding elements on the other. These connecting devices are described below.

A cladding element 14 is shown schematically in Fig. 2. This is designed as a flat square element and consists primarily of metal. An edge profile unit 30 is present all the way around the outer edge, which is preferably designed as a rectangular hollow profile. The upper and lower edge profile units 30 have a self-contained, continuous recess 32 in the form of an elongated hole in their respective side edge areas.

In Figs. 3 and 4, a first variant of a connecting device 16.1 is shown, which has a first connection unit 18.1, which is designed as a known pipe coupling for connecting to scaffolding pipes. A second connection unit 20.1 is connected to the first connection unit 18.1, which consists of bent round steel and has a

Spatial structure as follows. In a plan view, the second connection unit 20.1 essentially forms a U-shaped contour, with the web being connected to the first connection unit

18.1 is connected. At each flange end of the U-shaped structure, an upwardly pointing free end 24 of a rod element 22 is connected, such that in a side view (Fig. 3) an essentially L-shaped contour is obtained. The edge profile units of the cladding elements are suspended in this free end 24 via their recesses 33.

Fig. 5 and 6 show a further variant of a connecting device 16.2, which is similar in its basic structure to the connecting device 16.1. The same first connection unit 18.1 is used as a pipe coupling. However, the spatial structure of the second connection unit 20.2 is modified in that the U-shape seen in the top view is made much flatter, so that the distance between the free ends 24 of the rod elements 22 is much larger than in the embodiment according to Fig. 4. The connecting device 16.2 is preferably used in the corner area of a scaffold, which is explained in more detail below.

The connecting device 16.3 shown in Fig. 7 and 8 has, with regard to the second connection unit 20.1, substantially similar contours to the connecting device 16.1, but here the first connection unit is

18.2 designed as a wedge head clamping unit for connection to a perforated plate 48 of a scaffolding post.

Fig. 9 and 10 show a fourth embodiment of a connecting device 16.4, in which the first connection unit 18.2 is again designed as a wedge head clamping unit for

Connection to a perforated plate 48, the second connection unit 20.3 is formed from two separate rod elements 22 connected to the first connection unit 18.2 with an upwardly pointing free end 24.

The two rod elements 22 are each essentially bent in a U-shape when viewed from above, with one flange end connected to the first connection unit 18.2. The free end 24 is formed on the other flange end, pointing upwards, and engages with the recess of the corresponding edge profile unit of a cladding element. This connecting device 16.4 is suitable for use in the outer corner area of a scaffold.

Fig. 11 shows a schematic section of a Layher Blitz scaffold in the area of an outside corner. The connection unit 16.2 is used in the corner area. At the same time, a folded corner plate 72 is present in the corner area, which creates the connection between the incoming cladding element 14 and the outgoing cladding element 14. In the right-hand area, an end profile device 50 is screwed to the front edge of the cladding elements 14, which will be described further below. An end plate 70 is connected to the end profile device 50 using fastening means not shown in detail. The end plate 70 creates the sealing connection to an end wall 76.

Fig. 12 shows a schematic section of a Layher Blitz scaffold in the corner area and with the adjacent fitting field

between the incoming and outgoing cladding elements. Here too, a closing profile device 50 is used on the front sides of the cladding elements, to which a fitting plate 78 is attached in a sealing manner.

Fig. 13 shows a schematic section of a Layher all-round scaffold in the area of an outside corner, with the connecting device 16.4 being used in the corner area. Here too, a folded corner plate 72 is used in the corner area.

The cladding elements 14 already described have a protruding rubber sealing profile 38 all around. The dimensions of the rod elements 22 of the second connection unit 20.1 are dimensioned in conjunction with the arrangement of the recess such that the rubber profile seals 38 of the front sides of adjacent cladding elements 14 lie on top of one another in a sealing manner when the cladding elements 14 are suspended.

Fig. 14 shows a schematic section of a Layher all-round scaffold in the area of an outside corner, whereby, similar to Fig. 11, in the right-hand area, a cover plate 70 creates a sealing connection to a wall 76 via a cover profile device 50 fastened to the front side of the cladding elements 14.

Fig. 15 shows a schematic section of a Layher all-round scaffold in the area of an inside corner. A closing profile device 50 is connected to the front side of the two cladding elements 14 that arrive at right angles. The cladding elements 14 are held in place using the connecting devices 16.1 already described.

30

Between the two end profile devices 50 there is a bent corner plate, which is nailed to the end profile devices 50 on site after being cut to size.

Fig. 16 shows a schematic detailed perspective from the inside of the connection of a total of four cladding elements 14 to a connecting device 16.1 with two rods 22. It can be seen in particular that the recesses 32 are designed as elongated holes and are present continuously on the edge profile units 30.

Fig. 17 shows an end profile device 50, which is also considered to be essential to the invention. This end profile device 50 is attached to the front of the cladding elements 14. In Fig. 17, the front of the cladding elements (not shown) is located on the left edge of the end profile device.

The end profile device 50 has a thin-walled profile unit 52 designed as an extruded profile, which starting from a substantially rectangular base body contour in Fig. 17 has a double-walled projection unit 56 in the upper left area. The projection unit 56 has a continuous recess 64 in which a rivet nut 66 is fastened. By means of a screw, the end profile device 50 can thus be connected in a simple manner to the respective cladding element 14, which also has a screw-in opening for this purpose.

In Fig. 17, the profile unit 52 has a recess 53 on the underside that runs through it in the longitudinal direction, through which a solid profile unit 54, which is designed as a rectangular wooden strip, is arranged inside the end profile device 50. The lower edge of the solid profile unit 54, which is accessible from the outside, is essentially flush with the wall areas to the right and left.

the profile unit 52. To secure the position within the profile unit 52, a blind rivet unit 55 running through the solid profile unit is present.

In the right-hand side area, the profile unit 52 has a piping recess 58, within which a piping of a tarpaulin can be inserted to connect a tarpaulin. On the opposite left-hand side of the profile unit 52 in Fig. 17, a further recess 60 is formed which is open to the outside, into which a sealing profile 62 protruding outwards is inserted, such that when the end profile device 50 is attached to the cladding elements, the sealing profile 62 rests sealingly against the sealing profile of the cladding elements 14.

15

The end profile device 50 offers a simple and reliable connection option for corner area sheets, compensation area sheets or other connection sheets, for example in the wall area. The respective cover or sheet can be cut on site to the corner or compensation dimensions to be observed and can be easily nailed to the wooden strip 54 of the end profile device 50. It is also possible to easily connect tarpaulins with piping for sealing purposes. This gives the scaffolding builder a component with which he can easily seal problem areas on site.

In a variant not shown, the rod elements of the second connection units are present in the lower area pointing upwards and the second connection areas arranged above them are present with rod elements pointing downwards.
