Definitions

  • the invention relates to plate stiffening profiles of thin sheet metal.
  • the object of the present invention is to remedy these disadvantages.
  • This invention as it stands characterized in the claims, solves the problem of defining a process and creating a device allowing the direct transformation of the edges of a thin sheet to obtain a usable stiffening profile in particular to constitute a framework.
  • the figures represent a prepainted sheet 10 comprising on at least one of its sides, going towards the edge of said side, two very close fold lines 11 and 12 intended for carrying out a plunge 20 , followed by three lines of parallel folding spaced 13 , 14 and 15, delimiting strips 30, 40, 50 and 60 constituting after folding the sides of the corresponding beam 80 , one of which, 13, 14 or 15 comprises multi-perforations 70 intended to facilitate manual production of the corresponding fold and of the snap-fastening of the straight edge 16 of the end strip 60 behind the grooving 20 of the plate 10 .
  • the sheet 10 itself is used as a blank to obtain a beam lateral reinforcement 80 integrated, without resorting to welding or gluing, by first simply making multiperforations 70 along a fold line 15, then mechanical folding, along the other lines, using for example a roller profiling machine, before lateral closing of the beam 80 by snap-fastening behind the routing 20 .
  • each corresponding to an embodiment of the reinforcing beam 80 each corresponding to an embodiment of the reinforcing beam 80, it is noted that, according to the fold line 13, 14 or 15 which is chosen to carry out the multi-perforations 70, the final operation, allowing to engage the edge 16 of the strip 60 behind the plunge 20 will consist, for the multi-perforations 70 in the line 15, in ensuring the folding of corresponding alpha angle, according to this line 15 (fig. 3), for the multi-perforation 70 in line 14, to ensure a right-angled folding inwards, in line 14 (fig.4) and for multi-perforations 70, in line 13, to also ensure a right-angled folding inwards, but following line 13 .
  • the strip 60 having been, in these last two embodiments, pre-folded at an adequate alpha angle.
  • the strip 60 is widened and pre-folded at a beta angle, towards the outside, before the final folding, at the same beta angle as the strip 50 with respect to the line 14 comprising the multi-perforations 70, the width of the said strip 50, having been determined so as to obtain the clipping of the fold 15 behind the plunge 20.
  • the clipping of the edge 16 of the strip 60 or of the fold produced along line 15 of the beam 80 can be obtained manually or mechanically by simple folding at the level of the line comprising the multi-perforations 70 followed by a pressure.
