Description

[0024] 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.

[0025] Show in the drawing:

[0026] FIG. 1 A scaffolding decking with a supporting frame and a walkable decking plate in a view from below;

[0027] FIG. 2 Scaffold decking according to FIG. 1 is a sectional view;

[0028] FIG. 3 The scaffold decking as shown in FIG. 1 is a partial front view;

[0029] FIG. 4 a cross beam of the scaffold decking according to FIG. 1 in an optional detailed perspective view;

[0030] FIG. 5 A longitudinal member of the scaffold decking according to FIG. 1 in an optional perspective detail view; and

[0031] FIG. 6 a block diagram with individual process steps of a process for producing the scaffolding decking shown in FIG. 1.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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

[0040] 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

[0041] or back section 44 of cross profile 20. It should be noted that the two wall legs 42 may have

[0042] 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).

[0043] A groove 50 with a width B is formed between the hook 40 and the respective assigned wall leg 42.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] The scaffolding decking 10 erected in the manner described above is therefore particularly easy and inexpensive to manufacture and repair.

[0048] In the following, the ingenious process for the fabrication of the above-explained scaffold decking 10 with additional reference to FIG. 6 is explained.

[0049] 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.
