Definitions

  • the present invention relates to a profiled sheet-metal roofing element for buildings.
  • a profiled sheet-metal roofing element for buildings known from Italian utility model No. 209011 has:
  • the first inverted U-shaped rib has, in cross-section, two inclined sides which diverge downwardly from its upper surface.
  • This shape involves the risk that, in the event of substantial vertical loads being applied to the roofing (for example, due to a large depth of snow or to its being trodden on) this rib tends to open out until its vertical flange is disengaged from the retaining tooth of the adjacent sheet-metal element, thus prejudicing the stability of the roofing.
  • the subject of the present invention is a profiled sheet-metal element of the type specified above, the main characteristic of which lies in that fact that the first, inverted U-shaped rib has, in cross-section, an upper, substantially arcuate portion and a lower portion comprising two flat sides inclined to the vertical so as to converge downwardly.
  • the element 1 has, at one end, a transverse rib 3 having, in section, a substantially inverted U-shaped profile with an upper substantially arcuate portion.
  • This upper portion has a convex top portion 4 and two side walls 5 also having convex profiles and connected to the top portion 4 by two short substantially vertical portions 6.
  • Two flat side walls 7 extending downwardly from the lower ends of the convex side walls 5 are inclined to the vertical so as to converge downwardly.
  • the inclination of the walls 7 to a vertical plane may be, for example, of the order of 15°.
  • the rib 3 At the base of the inclined wall 7 which is situated on the outer side of the element 1, the rib 3 has a portion 8 which is bent horizontally towards the interior of the rib 3 and an end flange 9 which is bent vertically.
  • the sheet-metal element 1 In the vicinity of its opposite end to the rib 3, the sheet-metal element 1 has an engagement rib 10 which is not as high as the rib 3.
  • the engagement rib 10 comprises a shank constituted by two vertical portions 11 and an enlarged head 12 facing the interior of the element 1 to form a retaining tooth.
  • the sheet-metal element 1 has an end portion 13 which extends beyond the engagement rib 9.
  • the end portion 13 of the sheet-metal element 1 is fixed by means of screws 14 or equivalent fixing means, to the purlins 15 on which the roofing bears.
  • the hollow rib 3 of an adjacent sheet-metal element is then engaged on the engagement rib 10 of the element 1 so as to engage its vertical flange 9 against the lower surface of the engagement tooth 12.
  • the joint thus formed between two successive sheet-metal elements involves no risk of disengagement, even under the effect of large vertical loads applied to the roofing.
  • the rib 3 tends to close up under the effect of such loads, so that the lower surface of the retaining tooth 12 of the rib 10 fixed to the battens supporting the roofing is clamped more tightly.
  • the curved profile of the upper portion of the rib 3 ensures better distribution of vertical loads applied and the central portion 4 connected to the two curved side portions 5 by the short vertical portions 6 achieves a guiding effect in the profiling of the sheet-metal element, as well as constituting a stiffening.
