  • the scaffold base body 16 is formed by forming a sheet metal blank.
  • the scaffolding floor body 16 provides a stepping surface 20 in a stepping surface area 18 that is oriented essentially upwards when the scaffolding floor element 10 is integrated into a scaffolding.
  • a large number of nub-like or ring-like or slot-like formations 22 can be formed protruding upwards in order to increase the stability on the one hand and the slip resistance on the step surface 20 on the other hand.
  • Transition regions 28, 30 are formed in lateral edge regions 24, 26 of the tread surface region 18 that are spaced apart from one another in the transverse direction Q, in which the tread surface region 18 merges into the respective side wall regions 32, 34.

  • the longitudinal direction L, the transverse direction Q and the height direction H are a coordinate system for the scaffolding floor element 10 and can be orthogonal to one another, for example.
  • the height direction H can essentially correspond to a vertical direction, so that the stepping surface area 18 is oriented upwards with its stepping surface 20 in the height direction H or in the vertical direction.
  • reference is made in the following to an orientation upwards or an orientation downwards this is to be understood in the context of this intended incorporation of a scaffolding floor element into a scaffolding.
  • the scaffolding floor element 10 in its transition areas 28, 30 or side wall areas 32, 34 is described. Since the scaffolding floor element 10 is basically the same with regard to these design aspects in its two side areas, ie z. B. can be mirror-symmetrical, in the following only reference is made to the 2 Areas shown on the left, ie the transition area 28 and the side wall area 32. The relevant statements apply equally to the formations on the other side. However, it should be pointed out that, in principle, the scaffolding floor element 10 can also be designed in its two side areas with non-identical transition areas or side wall areas.

  • a depression 52 is formed between these two rib-like formations 42, 44, which has a depression depth E with respect to the apex regions 48, 50.
  • the depression depth E is smaller than the projection height V, so that the accumulation of impurities in the transition area 28 can be reduced.

  • curvature-like deformation areas K i With such a small radius of curvature R, a comparatively strong deformation of the sheet metal material is generated, so that the dislocations generated in the process are anchored in the lattice structure of the sheet metal material and lead to a significant stiffening of the scaffolding floor body 16.
  • the provision of the curved deformation areas K i and the rib-like formations 42, 44, 46 generated thereby produce an accumulation of material in the transition area 24, which also contributes to increasing the stability.

  • the successive curved-like deformation regions K 2 and K 3 have the same curvature orientation as one another.
  • the rib-like formation 44 is essentially provided by the curved-like deformation areas K 5 , K 6 , K 7 and Ks , while the rib-like formation 46 is provided by the curved-like deformation areas K 8 , K 9 and K 10 .
  • the respective apex regions 48, 50 lie in the region of respective essentially non-curved connecting regions B 1 and B 3 connecting two curved deformation regions K 2 , K 3 or K 6 and K 7 .
  • the rib-like shaping area 46 also has a substantially uncurved connection area B 6 between the two curved-like deformation areas K 9 and K 10 .
  • the connection area B 6 is longer than the connection areas B 1 and B 3 , so that on the rib-like formation area 46 in particular by the connection area B 6 in connection with these laterally delimiting curvature-like deformation areas K 9 and K 10 a comparatively large contact surface is formed, over which a scaffolding floor element 10 is guided, for example together with other scaffolding floor elements on a transport vehicle or a transport pallet fixing tension belt. In this way, a punctiform or line-like interaction between a tensioning belt and the scaffolding floor element 10 that leads to a heavy load on the scaffolding floor element 10 can be avoided.
  • the side bolster 36 of the side bolster area 32 closes in a side bolster section extending from the rib-like shaping area 46 or the curved reshaping area K 10 downwards in the vertical direction H, i.e. towards the end profile area 40 and inwards in the transverse direction Q, i.e. towards the other side bolster region 34 56 of the side wall 36 to the transition area 28.

This also contributes to stiffening, particularly in the area of the side panel area 32 or the side panel 36 of the same at.
  • the scaffolding floor body is in the end profile area 40 formed at the end area 62 of the side wall area 32 remote from the transition area 28 16 with two profile transverse regions 64, 66, which preferably extend essentially parallel to one another and preferably in the transverse direction Q, and which are connected to one another in a profile transition region 68.

  • the profile transition area 68 adjoins the first profile transverse area 64 in the area of a further rib-like formation 72 which is formed essentially towards the other side cheek area 34 and in the direction of the tread surface area 18 obliquely downwards.

  • This is achieved in particular by the fact that a respective extension length P of the first transverse profile area 64 or the second transverse profile area 66 in the transverse direction Q is greater than their distance A in the vertical direction H.
  • the two transverse profile regions 64, 66 can have the same extension length P in the transverse direction Q and in the transverse direction Q each other completely be positioned to cover.
  • the second transverse profile area 66 ends in its end region remote from the profile transition area 68 in the transverse direction Q at a small distance in front of the side cheek section 58 of the side cheek 36.
  • the end profile area 40 in particular with its first transverse profile area 64 and the two rib-like formations 70, 72 delimiting it in the transverse direction Q, forms a support area 74.
  • the two rib-like formations 42, 44 essentially form a counter-support area 76.

That scaffolding floor element 10 of figure 5 differs from the preceding with respect to the 3 and 4 scaffolding floor element described in detail essentially in the design of the end profile area 40. The differences to the previously described embodiment in this end profile area 40 are therefore essentially discussed below.
