Definitions

  • Sealing and insulation are properties that are increasingly sought after in the construction of roofs, and in particular the roofing of industrial buildings.
  • these buildings are very often covered with corrugated sheets and in particular asbestos-cement sheets, so that the maintenance of the roof, and even its installation or that of an insulating coating, raise safety problems. either due to the fragility of the plates or the difficulty for staff to move on a wavy surface.
  • the object of the present invention is to remedy these drawbacks by providing a covering covering which has sufficient strength to support the execution or maintenance personnel, as well as a flat surface whatever the support on which it is placed.
  • the subject of this invention is in fact a covering covering which comprises a plate of foam material, flat and of substantially constant thickness, in which is embedded a reinforcing and stiffening reinforcement having meshes of small dimensions, and which adheres to a support along spaced lines.
  • the support may consist of corrugated sheets already placed on the roof, the sheet of foam material adhering to the crests of the corrugations of these sheets, or be fixed directly to the purlins, or the like. elements, of the roof.
  • the coating allows safe circulation by maintenance or execution personnel, the reinforcement ensuring both a flat external surface and sufficient mechanical resistance.
  • the frame comprises two plies: a lower ply with fine meshes for retaining the foam material and stiffening the plate, and an upper ply with wide meshes ensuring the mechanical strength of the assembly.
  • the invention also extends to the coating process which consists in placing a flat and taut reinforcement, having relatively fine meshes, on a support comprising projections spaced and parallel to each other, in depositing on this reinforcement a foaming, liquid product, which solidifies almost instantaneously when adhering to the support after having "wet" the underside of the frame, and swells around this frame to form a flat plate.
  • a foaming, liquid product which solidifies almost instantaneously when adhering to the support after having "wet" the underside of the frame, and swells around this frame to form a flat plate.
  • One or more additional layers may possibly be deposited on the first.
  • a waterproof and insulating coating is thus obtained, which can be executed and maintained in complete safety, and which can be formed on a building under construction as well as being adapted on an existing building, in particular for transforming a corrugated roof into a surface roof. plane.
  • the covering covering object of the invention comprises corrugated plates 1, which are fixed in the usual way on purlins, but whose fixing has not been shown so as not to complicate the drawing.
  • a reinforcing ply 4 which is formed, for example, by a lattice, a grid, expanded metal, or even a glass cloth.
  • This ply has meshes of relatively small dimensions, for example square meshes with a side of 6 mm, and it is stretched so as to be strictly flat.
  • a second ply 6 having large meshes, for example square meshes with a side of 10 cm.
  • This second ply is constituted, for example, by welded mesh plates, expanded metal, a perforated sheet, a grid, a grating, ribbed or not, a plastic net or the like, having great mechanical resistance.
  • the two plies 4 and 6 are embedded in a foam material 8, which adheres to the ridges 2 of the corrugated plate 1, and constitute a reinforcement of this material.
  • the foaming product is, for example, a polyurethane, a polycarbonate, a polyurea, having good qualities of adhesion to the support 1 and capable of solidifying very quickly around the plies 4 and 6 by presenting an exterior surface 9 which is really flat. .
  • This coating according to the invention is also formed on site.
  • the fine-mesh ply 4 is first placed on the ridges 2 of the plate 1 and stretched so as to form a strictly flat surface, then the second ply 6 is placed on the first and the foaming product, in the liquid state, is deposited on the two layers.
  • This product solidifies almost instantaneously, in fact in two or three seconds, so that it solidifies before having had time to reach the hollows 10 of the waves of the corrugated plate 1, and forms only below the sheet 4 a thin layer 12 (fig. 2) which adheres closely to the vertices 2 of the ridges of the plate 1.
  • the fine meshes of the sheet 4 are large enough to allow part of the liquid to pass through them before solidification occurs, but nevertheless small enough to limit this penetration of the liquid into the thin layer 12 and prevent the liquid to flow freely towards the troughs of wave 10.
  • These meshes must have between 5 and 20 mm.
  • An air space or pocket 21 is then left free in each wave trough, between the plate 1 and the reinforced foam 8 of the coating, which improves the insulation coefficient.
  • the dimensions of the meshes of the second ply 6, as well as the material which constitutes this ply, are chosen so as to give the latter a high mechanical resistance, so that it is capable of supporting relatively high loads and in particular a operating or maintenance personnel.
  • the coating obtained thus ensures not only the waterproof and insulating covering of the roof, but also the safety of the personnel who installs or maintains it.
  • the two plies 4 and 6 are merged and united into a single one, 16, which rests on all of the corrugation ridges of the plate 1 and is, like the plies 4 and 6, embedded in a foam product 18 of which it constitutes the frame.
  • the ply 16 ensures both the stiffening of the coating and the retention of the liquid product, while giving the assembly a high mechanical strength which allows it to withstand heavy loads while remaining flat.
  • This frame 16 may, for example, be made of a ribbed expanded metal or glass cloth, which allows the coating to be produced at a lower cost.
  • a mesh of high-strength plasticized glass fabric having the following characteristics is used:
  • This trellis has a mesh wide enough for the foaming liquid to pass through and can thus wet the tops of the supports on which the foam will hang by gluing.
  • the meshes are fine enough that at the projection, there passes very little foaming liquid which would be lost for the realization of the coating.
  • the whole of the plate 8 provided with the reinforcing reinforcement constituted by the plies 4 and 6 or by the single ply 16 is rigid enough not to rest on the support formed by the corrugated plate 1 only along the ridges 2, that is to say along lines spaced apart.
  • a reinforced foam plate can also be carried by other types of support.
  • it can be fixed directly on successive purlins 20, 22 of a roof and constitute the cover alone.
  • a frame 24, comprising one or more reinforcing plies, is then stretched directly on the purlins 20, 22 and embedded in the foam product 28 which solidifies around it by adhering to the top of each of the purlins 20, 22. Thanks to the frame 24 the outer face of the cover is flat and the assembly has sufficient rigidity and provides effective insulation and sealing.
  • one or more additional layers of foaming product can be sprayed onto the reinforced foam plate 8, 18, 28, if necessary, to give the coating the appropriate thickness.
  • the foaming product plate 8, 18 or 28 is in fact formed from planar elements, which need only be fixed locally on their support.
  • This coating is particularly advantageous for the protection of corrugated roofs and in particular for transforming a corrugated cover into a cover with a flat surface. It thus makes it possible to take advantage not only of the qualities of the coating itself, but also of a reduction in developed area and therefore in heat flux for the same thickness of insulation, while improving the external appearance.
