  • Wide parts of the first area of the invention have for its object to make a scaffold floor available, in which the connection and / or design of in particular two longitudinally oriented, relatively wide floor profile parts and possibly other components is of a more favorable type in terms of production technology, load and material than with known scaffolding floors. It may be of importance here that at least approximately in the longitudinal center with the aid of permanently attached suspension structures without substantial welding in the longitudinal seam area.

  • the design can also provide that the cross sections of the snap-in connection parts are designed and arranged in the main bending zones of the bending limbs of the suspension elements designed as target bending zones free of use or at least low in load.
  • the cross-connection caps are C-shaped or U-shaped components, the horizontal legs of which, if necessary with substantially slot-shaped notches in one of the joining parts, engage under surfaces of component walls of the base profile parts and fit on Access points are welded to them.
  • the middle safety hook can be welded directly onto the vertical, smooth outer surface of the respective cross-connection cap, avoiding an insertion pin.

  • the support part 265 lies outside the part of the scaffolding floor 45 delimited by the running surface 55, that is to say in front of the contact surface 252 of the cross-connection cap 54, against which the stop surface 260 of the hook 46 is abutted.
  • the outer contour of the support part 265 initially runs parallel to the upper and lower pin outer surfaces 262.1 and 262.2 of the fastening part 250 both in the upper and in the lower partial area.
  • the lower boundary 264 of the support part 265 goes from an outer, lower, upwardly extending rounding surface 271 in a vertical inner mouth wall 272 of the suspension mouth 47 over. This is adjoined at the top by an inner wedge surface 273, which extends as far as the contact surface 275 of the suspension mouth 47.
  • the contact surface 275 has a width 276, which is 6 mm, for example.
  • the hook-in jaw 47 is bounded towards the front next to the support surface 275 by a downward-extending inner wedge surface 274, which has approximately the same steep inclination as the wedge surface 273. It limits the hook part 277 inwards together with an outer, vertical jaw wall 278, the bottom merges into an insertion bevel 279, which is followed by the lower hook end surface 280 as a curve.
  • the hook part 277 is bounded on the outside by a hook surface 281 which is inclined upwards in the direction away from the scaffolding floor 45, said hook surface extending somewhat above the contact surface 275 and passing there into a vertical abutment surface 282 of the support part 265.
  • the vertical abutment surface 282 lies at a distance 284 in front of the abutment surface 260. This is the greatest distance from the abutment surface 260, so that the vertical abutment surface 282, if necessary, when the hook 46 hits an obstacle or when the scaffolding floor 45 falls vertically onto the hook 46 hits with the upper rounding 283.

  • the connecting web 290 merges into the node area 291, which, in addition to the hanging mouth 277, serves to support the forces acting on the supporting part 265 and this into the three webs, namely the wall part assigned to the inner wedge surface 273 and the vertical wall 268, the diagonal web 267 and the connecting web 290 transferred together with the top wall 256.2.

This enables good production using suitable techniques, particularly in the light metal extrusion process.
  • the distance 284 between the vertical abutment surface 282 and the stop surface 260 is preferably 32 mm, while the bearing surface 275 is 293 below the upper limit 263, this dimension 293 preferably being 20 mm, while the hook part 277 to its lower tip 280 is about 24 mm long.

  • the entire suspension hook 46.3 is expediently welded, for example with the aid of a suitable auxiliary device, all around to the outer boundary surface of the vertical wall 210 of the cross-connection cap 54, so that the height of the support surface 228 of the suspension jaw 227 is at the same height as the support surface 275 of the other two suspension hooks 46.1 and 46.2 or is slightly above.
  • the hook 46.3 is made of one Light metal extruded profile formed, which has the shape shown in Fig. 7, wherein its lateral boundary surfaces result from simple cutting.
  • the design of the hook 46.3 largely corresponds to the design of the support part 265 of the hook 46.1 and 46.2.
  • An essential difference is the vertical wall 237, which has been slightly changed in its design and has been moved forward to the position of the abutment surfaces 260 at a distance 284 from the vertical abutment surface 282, the upper and lower edges of which are only slightly rounded.
