Description

The invention concerns a scaffolding decking, such as this is used as a walk-on working platform for scaffolding, in particular for scaffolding. Also, the invention concerns a process for manufacturing such a scaffolding decking.

Scaffolding decks available on the market have a supporting frame made of longitudinal and transverse profiles that are welded or riveted together. The support frame is usually made of metal and is used for the storage and support a walk-on covering plate, which can be made of wood, plastic or a composite material, for example. The covering plate can be screwed or riveted to the support frame. Such scaffolding decks are also known in the construction industry as so-called frame panels or combination decks. The scaffolding decks are cost-intensive to manufacture and, in the event of damage to the longitudinal or transverse profiles of the supporting frame, are difficult to repair, especially as the decking plate must be detached from the supporting frame and, in addition, the rivet or welded connections of the transverse profiles must be destroyed to loosen them.

It is, therefore, the task of the invention to specify a durable scaffolding decking which has a sufficiently high load-bearing capacity for construction purposes and which is

easier and cheaper to manufacture. In addition, it is the task of the invention to specify a cost-effective process for manufacturing such a scaffolding decking.

The scaffolding decking according to the invention has the features stated in claim 1. The procedure according to the invention is indicated in claim 11.

The scaffolding decking according to the invention is essentially characterized by the fact that the cross profile(s) is/are hooked into the two longitudinal profiles of the supporting frame and is/are held or secured in position solely by the supporting or decking plate in its/their longitudinal profiles, i.e. is/are hooked into the longitudinal profiles. In other words, unintentional loosening of the hook connection between the cross profile(s) and the longitudinal profiles is prevented or prevented by the covering plate attached to the two longitudinal profiles. The scaffolding decking according to the invention can thus be manufactured more simply and cost-effectively overall. Welding or riveting the cross profile or the individual cross profiles to the longitudinal profiles is completely unnecessary, which means that the covering plate has a dual function. This connects the longitudinal profiles to each other and thus enables sufficient bending and torsional stiffness of the scaffolding decking.

On the other hand, it serves as a locking or securing device for the cross profile interlocked with the longitudinal profiles or the cross profiles interlocked with the longitudinal profiles, so that the cross profile or profiles are secured against unintentional disconnection from the longitudinal profiles. According to the invention, each cross profile has two wall legs which are connected to each other via a back section. In this case, the transverse profile(s) therefore have a substantially U-shaped cross-sectional shape and are/are preferably designed 2s open towards the covering plate. Such a U-shaped cross-section shape enables the cross sections to be realised with a sufficiently high load-bearing capacity. According to the invention, the two wall legs have angled free edge sections, preferably to the outside, to provide the largest possible contact or support area for the covering plate. After the invention, the load-bearing capacity and the torsional rigidity of the scaffolding beam can be further improved by the fact that each transverse profile of the support frame is provided with several hooks, which engage in recesses in the longitudinal profiles corresponding to the hooks. According to the invention, the recesses in the longitudinal member(s) for the respective transverse profile(s) are preferably slot-shaped.

This reduces material weakening of the side members to a minimum. Slots can also be produced without great effort, for example using a laser cutting process or using machining, in particular by sawing, at low cost and with great dimensional accuracy.

With its hook(s), the cross-member(s) can be arranged advantageously in the recesses of the side rails in the form fit of the sliding play. This prevents unwanted warping of the supporting frame during fabrication and use of the scaffolding decking.

After the invention, the covering plate rests on a profile heel of the longitudinal profiles. This means that the longitudinal profiles can protect the decking plate laterally in the sense of a frame around its longitudinal edges. Unwanted mechanical damage to the decking plate during transport or the use of the scaffolding decking can be avoided.

The recesses or slots of the longitudinal profiles can extend from the profile heel of the longitudinal profiles into (inside) side wall area of the longitudinal profiles. This allows the cross profile or the cross profiles to be hooked into both longitudinal profiles in a simplified manner, if necessary at the same time. At the same time, the cross profile(s) can be aligned with its/their supporting surface(s) 25 to support the decking plate in alignment with a bearing surface of the longitudinal profiles, for example, formed by the paragraph above. Overall, a flat contact and support of the covering plate on the longitudinal as well as on the cross profile or the cross profiles can be achieved.

After the invention, the covering plate rests on the cross profile or profiles of the support frame. This allows the decking plate to be supported in the area of the cross profile(s) (free of play). As a result, the covering plate can be realised in total thinner, thus lighter, or from a less load-stable and therefore cheaper material.

After the invention, the covering plate can be riveted, preferably solely, to the longitudinal profiles of the support frame. Such riveted joints can be realised cost-effectively and offer advantages not least due to the cost-effective automation of riveting processes—especially for mass production of scaffold decks.

According to the invention, the longitudinal profiles of the support frame are preferably hollow profiles. This allows sufficient load-bearing scaffolding decks to be achieved with a low mass at the same time. Overall, this is advantageous for the handling of the scaffolding decking.

The ingenious process for the fabrication of a scaffolding decking described above comprises the following steps:

• Provision of the longitudinal profiles and one or more cross profiles as well as the covering plate;
• Hook each cross profile into the longitudinal profile under the support frame:
• Placing the decking slat on the longitudinal profiles of the support frame; and
• Securing one cross profile or profiles in its/its position hooked into the longitudinal profiles solely by fixing the covering plate to the longitudinal profiles of the support frame, in particular by riveting it firmly.

With the ingenious method, the scaffolding decking can be produced simply and cost-effectively. Hereby eliminating the need for welding or time-consuming and costly fastening of the cross profile(s) to the longitudinal beams using separate fastening means, such as screws or rivets.

It should be noted that the inventive process can easily be automated so that the scaffolding decking can be produced cost-effectively in mass production. Hooking the cross profiles into the side members can be done simultaneously.

In summary, the invention concerns a scaffolding decking for scaffolding in the building sector, with a supporting frame with two longitudinal profiles and with a transverse profile or with several transverse profiles via which the longitudinal profiles are connected to each other.

The scaffolding decking has a decking plate which is attached to the longitudinal profiles, whereby the cross profile(s) is/are hooked into the two longitudinal profiles and are held or secured solely by the decking plate in its/their position hooked into the longitudinal profiles. Moreover, the invention relates to a cost-effective and easy to carry out a method for producing a scaffolding above.

Further advantages of the invention result from the description and the drawing. The form of execution shown and described is not to be understood as an exhaustive list, but rather has exemplary character for the description of the invention.

FIG. 1 shows a scaffold decking 10 for construction or working scaffold (not shown) in a schematized subview. The scaffolding decking 10 has a walk-on decking plate 12 which extends along the longitudinal axis 14 of the scaffolding decking 10. The covering plate 12 preferably consists of wood or a wood material, but can also consist of plastic, composite material or metal.

The scaffolding deck has a supporting frame, which is labelled 16 in total. The support frame 16 is used to support and stiffen the decking plate 12 and to detachably attach the scaffolding decking 10 to other scaffolding parts of the construction or working scaffolding. Support frame 16 has two longitudinal beams or longitudinal profiles 18 and one or more cross beams or cross profiles 20.

The longitudinal profiles 18 can each have connecting means 24 at their free end sections 22, using which the scaffolding decking 10 can be attached in a known manner to vertically running scaffolding standards or to horizontally running scaffolding ledgers (not shown in each case), for example, hooked in. The longitudinal profiles 18 are each connected via the cross profiles 20.

In the design example shown, the support frame 16 has four profiles 20 as examples. However, the support frame 16 can also have less than four, for example, 2 or three, or even more than four cross profiles 20. The scaffold deck 10 can be provided at both ends with a profile fitting 25 preferably made of metal, as shown in FIG. 1 with a stroked line. The profile fitting 25 can be attached at both ends to the longitudinal profiles 18 and have or carry the connecting means 24. If required, such a profile fitting 25 can be used to provide edge protection on the face of the covering plate 12.

In FIG. 2 the scaffold deck 10 is shown in a cut-out detailed view and in FIG. 3 in a cut-out front view.

18 longitudinal profiles are each designed as hollow profiles and preferably consist of metal, for example, aluminium. The longitudinal profiles 18 can be designed in particular as so-called extrusion profiles. The longitudinal profiles 18 each have an upper side 26, an underside 28, an outside 30 and an inside. 32 The upper side 26 of the longitudinal profiles 18 is of stepped design. As a result, the longitudinal profiles 18 each have a paragraph 34. Paragraph 34 forms a support area 36 for the covering plate 12 and the covering plate 12 is in direct contact with the support area 36. Here, the covering plate 12 is fastened solely to the longitudinal profiles 18 and riveted via several rivets 38 (FIG. 3) with the longitudinal profiles (only). The rivets 38 of a longitudinal profile 18 are arranged spaced apart in the axial direction. This holds the covering plate 12 permanently in position on the longitudinal profiles 18 of the support frame 16. 36 The support area can have several ridges or grooves. 39, each of which is arranged axially. The corrugations are arranged laterally offset to each other and serve to provide a non-slip and wobble-proof support for the decking plate 12 on the longitudinal profile 18 preferably into the material of the covering plate 12.

The cross profiles 20 have several hooks 40 at both ends, over which the cross profiles 20 are hooked to the two longitudinal profiles 18.

The hooks 40 are clearly visible in the detail view of a single cross profile 20 of the support frame 16 as shown in FIG. 4 (FIG. 1). The hooks 40 are moulded onto the cross profile 20 and preferably of identical design. Because the hooks 40—relative to the longitudinal axis 14 of the scaffold deck 10 (FIG. 1)—are arranged in the axial direction at a distance A from one another on the respective cross profile 20, a particularly stable and torsionally rigid connection can be achieved between

the cross profiles 20 and the side members 18. The cross profiles 20 each have a U-shaped cross-section. Two parallel or essentially parallel wall legs 42 are connected to each other via a connection

or back section 44 of cross profile 20. It should be noted that the two wall legs 42 may have

free edge sections 46 angled or bent outwards. The covering plate (FIG. 13) to the scaffolding decking 10 can be additionally supported over a large area on the support or surface 48 of the edge sections 46 of the cross profiles 20 which is assigned to the decking plate 12. The surfaces 48 of the wall legs 42 of the cross profiles 20 are aligned with the support area 36 of the longitudinal profiles 18 (FIG. 3) in a direction orthogonal to the longitudinal axis 14 of the scaffold deck 10 (FIG. 1).

A groove 50 with a width B is formed between the hook 40 and the respective assigned wall leg 42.

In FIG. 5 one of the longitudinal profiles 18 of the support frame 16 of the scaffold deck 10 according to FIG. 1 is shown in an exposed perspective detail section. The recesses 52 are arranged in pairs on the respective longitudinal profile 18 and have a distance A corresponding to distance A of the hook 40 (FIG. 4). The recesses 52 reach through each wall 54 of the longitudinal profiles 18. The recesses 52 extend from the upper support area 36 of the longitudinal profiles 18 transversely to the longitudinal axis 14 into the inside 32 of the longitudinal profile 18. This allows the cross profiles 20 to be simply hooked into the recesses with the longitudinal profiles 18 using the hooks 40 when assembling the scaffold deck 10 (FIG. 1). The wall 54 of the longitudinal profiles 18 engages in one of the grooves 50 of the respective cross profile 20 shown in FIG. 4. The width B of the groove is preferably matched to the material thickness (not indicated in the drawing) of the wall 54 in order to allow the cross profiles 20 to be mounted on the two longitudinal profiles 18 in the in axial direction relative to the longitudinal axis 14 (FIG. 1) with little play or with a positive fit. The recesses 52 can be produced using a laser cutting process or purely by cutting, for example by sawing.

The cross profiles 20 of the support frame are secured against disconnection from the longitudinal beams 18 solely by the covering plate 12 riveted directly to the longitudinal beams 18. This eliminates the need for time-consuming and cost-intensive riveting or welding of each cross profile 20 with the longitudinal profiles 18.

In the event of damage to one or more cross profiles 20 or longitudinal profiles 18 of support frame 16 (FIG. 1), only the rivet connections between the decking plate and the longitudinal beams (destructive) have to be loosened and the decking plate 12 lifted from support frame 16 in order to be able to replace the affected profiles of support frame 16.

The scaffolding decking 10 erected in the manner described above is therefore particularly easy and inexpensive to manufacture and repair.

In the following, the ingenious process for the fabrication of the above-explained scaffold decking 10 with additional reference to FIG. 6 is explained.

In a first step 102 the longitudinal and cross profiles 18,20 (FIG. 1) and the covering plate 12 are provided. In step 104 the cross profiles 20 are hooked into the longitudinal profiles 18 to form the support frame 16 (FIG. 1). In step 106, the covering plate 12 is placed on the longitudinal profiles 18 of the support frame 16 and in step 108 the cross profiles are secured in their hooked position into the longitudinal profiles by fixing the covering plate to the longitudinal profiles 18, in particular, riveted to them.
