Definitions

  • the invention generally relates to a device for mounting a one-piece floor element on a scaffold, as well as a floor element provided with this mounting device in accordance with the preamble of the main claim.
  • CH-A-536 913 Also known from CH-A-536 913 is a device for mounting a monoblock floor element between two horizontal crosspieces of scaffolding.
  • This floor element is provided at its four corners with hooking lugs ending in a bent part forming a stud directed downwards which engages in an opening made in the horizontal crosspiece of the scaffolding.
  • the device of this Swiss patent differs from the other devices described above simply in the fact that the bent part of an arc of a circle does not come to bear on the external periphery of the horizontal cross member but penetrates into an opening of the latter. this.
  • the floor elements are simply supported at their ends on the horizontal crosspieces of the scaffolding frames.
  • the object of the present invention is to improve the safety of workers working on scaffolding, thereby improving the mounting of floor elements on the scaffolding frames.
  • the invention therefore provides a device for mounting, on a scaffold, a monobloc floor element forming a complete section of floor extending between two vertical scaffold side frames, resting at its ends by lugs on horizontal crosspieces of said frames, said attachment tabs comprising rigid studs engaged in said horizontal crosspieces, characterized in that said stud of each tab integral with the ends of the floor element has a length greater than the diameter of the horizontal crosspieces and is engaged in a corresponding vertical diametral hole of said crosspieces to form a rigid semi-embedding of the floor element on the crosspieces.
  • the floor elements are no longer simply placed or supported at their ends on horizontal crosspieces, they are practically embedded on these crosspieces.
  • the rigidity of the mounting is greatly improved, as well as the reliability of the fixing of the floor element.
  • FIG. 1 There is therefore shown diagrammatically in FIG. 1 floor elements 10 according to the invention, fixed to horizontal crosspieces 11 of two lateral scaffolding frames.
  • the floor element 10 represented on the left in FIG. 1 has been drawn apart from the corresponding horizontal cross member 11, while the right element is shown mounted on the corresponding cross member 11, just like the central element 10.
  • Each floor element 10 is a one-piece element, forming a complete section of floor between two horizontal crosspieces 11 of the scaffolding frame.
  • This floor element can be made in various known ways, and it has the characteristic of being much more resistant and much lighter than a corresponding floor formed of wooden planks, and also being more resistant to weathering.
  • Each floor element 10 comprises four hooking lugs 12 which are provided substantially at its four corners, as indicated below.
  • Each lug 12 as best seen in Figures 2 and 3, has in cross section or in side view, substantially the shape of an S, a first end 13 is fixed on the underside 14 of the 'floor element 10, while the second end 15 of the lug 12 extends parallel to the first end 13, and substantially in extension of the upper face 16 of the floor element 10, in the longitudinal direction thereof this.
  • the two end parts 13 and 15 are joined together by a straight part 17 perpendicular to the two end parts 13 and 15.
  • the end part 15 is approximately half as wide as the end part 13.
  • This end portion 15 comprises a rigid cylindrical stud 18, one end of which is engaged in a hole in the portion 15 of the tab 12, and is secured to this portion 15 for example by welding, the cylindrical stud 18 extending towards the bottom perpendicular to the end portions 13 and 15 of the tab 12, over a length which is substantially equal to the thickness of the floor element 10 and which is in any case greater than the outside diameter of the cylindrical cross member 11 on which the floor element 10 is intended to be mounted.
  • each tab 12 is fixed, by its end part 13, to the underside 14 of the floor element 10.
  • the part 13 comprises two holes 19 corresponding to holes of substantially the same diameter 20 which are formed in the thickness of the floor element 10 and which are intended to receive cylindrical fixing tubes 21, the upper and lower ends of which are crimped, respectively on the underside of the part 13 of the tab 12 and on a metal plate 22 interposed between the upper surface 16 of the floor element 10 and the upper end of the tubes 21.
  • each attachment tab 12 has reinforcing ribs 23 as shown in FIGS. 2 and 3.
  • each transverse end end 24 of a floor element 10 comprises two hooking lugs 12 which are arranged, on this side 24, of the same way, as shown in Figure 1.
  • the lugs 12 provided on the other transverse end side 24 of the element 10 are in reverse position, as shown in Figure 1.
  • the nipples 18 of the two legs 12 on the same transverse side 24 are offset laterally in the same direction relative to the median longitudinal axis of the element 10, while the nipples 18 of the hooking lugs 12 provided on the other transverse edge 24 are offset in the opposite direction with respect to this median longitudinal axis.
  • the hooking lugs 12 of a floor element 10 are arranged two by two symmetrically with respect to the central midpoint of the element 10, constituted by the point of intersection of the diagonals of this floor element.
  • this arrangement makes it possible to arrange the floor elements 10 practically end to end, at the same level, with practically no surface discontinuity between two consecutive elements.
  • each horizontal cross member 11 For mounting the floor elements 10, each horizontal cross member 11 comprises four vertical diametrical holes 25 intended to each receive a cylindrical stud 18, as shown in FIGS. 1 and 2.
  • the assembly of the floor elements according to the invention is therefore extremely simple: it suffices to take a floor element 10 and bring it above these two horizontal crossmembers 11 for mounting, then to introduce the pins 18 of the four legs 12 provided substantially at the four corners of the element 10 in the corresponding holes 25 of the two horizontal crosspieces 11. Since the studs 18 have a length greater than the outside diameter of the horizontal crosspieces 11, each stud 18 protrudes slightly at its lower part outside the cross member 11. This arrangement makes it possible to produce a rigid semi-embedding of the floor element 10 at its ends on the horizontal cross members 11.
  • the floor element once mounted in place, forms a horizontal bracing of the scaffolding.
