DETAILED DESCRIPTION OF THE FIGURES

[0050] The scaffold platform plane 1 according to the present invention, which is shown in FIG. 1, is used to form a scaffold plane within a scaffold. In addition to the scaffold platform plane 1, this comprises several horizontal ledgers 30, vertical posts 40 and further scaffold components which will not be discussed in detail here. The scaffold platform plane 1 has several scaffold platforms 20 arranged in a plane and running parallel to each other, each of which is C-shaped in cross-section. The cross-sectional shape means that a high load-bearing capacity can be achieved with little material and low weight. However, if the scaffold platforms 20 are subjected to a point load, the load-bearing capacity may be insufficient, causing the scaffold platform 20 to bend severely. To prevent this and distribute the load over all the scaffold platforms 20, they are connected by a beam 10.

[0051] As can be seen in FIGS. 5 and 6 in particular, the beam 10 has two profiles 100, 200 that are inserted into each other in a longitudinally displaceable manner. The outer profile 100 is a tubular profile with a rectangular cross-section (see also FIGS. 7 and 8), in which the other profile 200 is accommodated. The other profile, or inner profile 200, has a U-shaped cross-section (see also FIGS. 9 and 10). The two profiles 100, 200 are connected by a screw 300 and at the same time held captive. In order to allow the two profiles 100, 200 to slide longitudinally without loosening the screw 300, the screw 300 is held in the link-like recesses 120, 220 of the two profiles 100, 200. These each have a recessed area into which screw 300 drops when the two profiles 100, 200 assume a certain position relative to each other. This achieves a self-locking effect that prevents the profiles 100, 200 from sliding longitudinally relative to each other

[0052] As FIGS. 7 and 8 show, the outer profile 100 has two side walls 101, 102, a top side 103 and a bottom side 104. Recesses 110 are formed in the side walls 101, 102 at equal distances from one another, each extending to the top side 103 or opening towards the top side 103. The recesses 110 serve for the reception of the scaffold platforms 20. On one side in each case, namely on the right side in the side view, the recesses 110 have an undercut area 111 which is adapted to an outer contour 21 of the scaffold platforms 20. On the other side, the recesses 110 are each bounded by a straight profile edge.

[0053] As can be seen in particular from FIGS. 9 and 10, the inner profile 200 has two side walls 101, 102, a top side 203 and a bottom side 204. Since the profile 200 has a U-shaped cross-section, the top side 203 is open throughout. Recesses 210 are formed in the side walls 201, 202 at equal distances from one another, each extending up to the top side 203 or opening towards the top side 203. The recesses 210 can be brought at least in some areas into overlap with the recesses 110 of the outer profile 100 when the profile 200 is inserted into the profile 100 to form the beam 10 (see FIGS. 5 and 6). The recesses 210 of the inner profile 200 are also undercut on one side in some areas, so that undercut areas 211 are formed. In the side view of profile 200, these are located on the left side of the recesses 210 (see FIGS. 9 and 10). The other side of the recesses 210 is bordered by a straight profile edge.

[0054] The fact that the profiles 100, 200 of the beam are inserted into each other in a longitudinally displaceable manner means that they can assume different positions, namely an end position, which is shown in FIG. 11 as an example, and enables a form fit between a scaffold platform 20 and the beam 10, and an assembly position, which is shown in FIG. 12 as an example, and which allows a scaffold platform 20 to be inserted into the recesses 110, 210 of the profiles 100, 200. In the assembly position, the recesses 110, 210 of the two profiles 100, 200 have a maximum common overlap area, so that the beam 10 can be attached from below to a scaffold platform plane 1 and connected to the scaffold platforms 20 of the scaffold platform plane 1. By longitudinally displacing the profiles 100, 200 relative to each other, a form fit can then be created between the scaffold platforms 20 and the beam 10, wherein the outer contours 21 of the scaffold platforms 20 engage in the undercut areas 111, 211 of the recesses 110, 210 of the profiles 100, 200 (see FIG. 2). engaging in the undercut areas 111, 211 of the recesses 110, 210 of the profiles 100, 200 (see FIG. 2).

[0055] In the figures, the undercut areas 111, 211 are each stepped to adapt to different outer contours 21, 21. This allows different types of scaffold platforms 21, 21 to be connected to the beam 10 in a form-fitting manner.

[0056] FIG. 3a shows an example of scaffold platforms 20 of a first type (see FIG. 3b) connected to the beam 10. These have outer contours 21 that engage with a first step of the undercut areas 111, 211 of the profiles 100, 200.

[0057] FIG. 4a shows an example of scaffold platforms 20 of a second type (see FIG. 4b), which have outer contours 21 that engage in a second step of the undercut areas 111, 211.

[0058] In order to secure the position of the external scaffold platforms 20 of a scaffold platform plane 1, the profiles 100, 200at each endhave front-side recesses 140, 240 in the side walls 101, 102, 201, 202 (see FIGS. 5 to 10). Accordingly, the beam 10 is held solely by the scaffold platforms 20 after it has been installed (see FIG. 1).

[0059] Further openings 130, 230 are provided in the profiles 100, 200 on their underside 104, 204 (see FIGS. 6, 8 and 10). These enable a tool (not shown) to be inserted in order to use the tool to effect a longitudinal displacement of the profiles 100, 200 relative to each other. In this respect, the opening 130 in the outer profile 100 is designed as a slot (see FIGS. 6 and 8).
