Definitions

  • the present invention relates to a waterproof building cover, in particular for an industrial building, of the type described in the preamble of claims 1 and 4.
  • the wind creates significant compression and depression forces, in places, on the roof (swirls, mask effect behind a wall or an emergence of the roof).
  • the forces are exerted on the exterior surface, therefore on the waterproofing coating, which ultimately stresses the load-bearing element and the structure of the building.
  • the rupture is located at the plane of bonding of the sealing coating on the washer, or by unbuttoning the fixing head through the washer, or by tearing off the fixing through the ribbed sheet steel.
  • the breaking values are relatively homogeneous, of the order of 900 to 1300 N.
  • the object of the invention is to provide a cover of the same type which is much faster and economical to implement and which practically does not allow the appearance of screws or the like on the underside.
  • the subject of the invention is, according to a first embodiment, a waterproof cover of the aforementioned type, characterized by the characterizing part of claim 1.
  • the cover according to the invention is characterized by the characterizing part of claim 4.
  • each row of fixing members comprises at least two of these members per raised area.
  • the invention also relates to a method of laying on parallel elements of the frame of a building, a cover comprising ribbed steel sheets, an insulating layer, in particular formed of plates adjacent, arranged on these sheets, and a sealing coating covering the insulating layer.
  • this method is characterized by the characterizing part of claim 11.
  • the laying method according to the invention is characterized by the characterizing part of claim 12.
  • the building cover shown without its waterproof coating in Figure 1 is placed on a series of purlins of parallel frames 1 made of I-irons with vertical core. It is made up of ribbed steel sheets 2 whose waves are perpendicular to the purlins, thermally insulating plates 3 rectangular, more or less compressible, arranged contiguously, members 4 for covering the covering, support members 5, and fixing screws 6.
  • the ribbed steel sheets 2 define raised areas 7 of relatively large width and much narrower wave hollows 8 with flanks 9 which are strongly inclined and at the bottom 10 parallel to the areas 7.
  • the connecting members 4 are relatively flexible and have, at least on their upper surface, a material compatible with that of the sealing coating with a view to bonding or welding it. It may be a strip, continuous or consisting of successive sections, or plates, as illustrated respectively in the right part and in the left part of FIG. 1, of thin metal coated with an appropriate material or made of the same material as the waterproofing coating and provided with a tear and tensile resistant frame.
  • the width of this strip, or the size of the plates can be of the order of 0.15 to 0.20 m.
  • the support members 5 are rigid members, in particular made of sheet steel at least 1 mm thick, protected against corrosion, for example by galvanization. It may be a succession of strips of elongated shape or washers, as illustrated respectively in the right part and in the left part of Figure 1.
  • the diameter of the washers can be of the order of 60 mm and the strip width of the order of 40 mm. These dimensions are in any case significantly less than the width of the flexible strip 4 or the dimension of the flexible plates 4.
  • each washer may have a deep-drawn bowl 11 having little near the same height as the heads 12 of the screws 6, and each strip can have two longitudinal ribs 11 having a height of the same order.
  • the screws 6 have a length greater than the sum of the thickness of the wings 13 of the purlins, the height of the ribbed steel sheets 2 and the thickness of the plates 3. They have, from their head 12, a smooth part 14, the length of which is greater than the sum of the thicknesses of the plates 3 and of the sheet metal 2, then a threaded part 15 and a self-tapping or self-tapping-tapping point 16. Alternatively, the screws 6 could be threaded over their entire height.
  • the tensile strength of the screws 6 depends on the spacing of the purlins, the vacuum forces due to the wind (and therefore on the geographic region) and on the spacing between the screws above the same purlin. For example, in France, for distances between purlins of 3 m and between fixings on the same purlin of about 0.50 m (every two waves of the sheets 2), the tensile strength of the screws 6 will not be less at 3000 N and will preferably be 5000 N with a safety factor of the order of 1.5.
  • the components 4 to 6 of the cover are dimensioned so as to obtain everywhere an approximate homogeneity of the tensile and / or tear performances with respect to the tearing forces perpendicular to the roof or parallel to this: tensile strength between the screws 6 and the purlins, tensile strength between the heads 12 of the screws 6 and the washers or strips 5, tensile strength, perpendicular to the roof, between the plates or the strip 4 and the washers or the strips 5, tear resistance between the plates or the strips 4 and the rod of the screws 6, with respect to forces parallel to the roof, resistance of the bonding or welding between the coating d '' sealing and plates or bands 4 and / or washers or strips 5.
  • the bowl or ribs 11 of the supporting members 5 reduce the risk of perforation of the coating sealing by the heads of the screws 6.
  • the screws 6 can pass through a metal tubular spacer 19 interposed between the upper face of the ribbed steel sheet 2 and the assembly 4-5. This makes it possible to avoid, under the effect of the maintenance circulation, the perforation of the sealing coating by the fixing heads 12, especially with flexible and compressible thermal insulation plates 3.
  • FIG. 6 and 7 differs from the previous one in that the tearing forces are transmitted to the purlins 1 indirectly, by means of ribbed steel sheets.
  • the sheets 2, which are made more rigidly than previously, are firmly fixed to the purlins, by means of fasteners 17 provided in each wave trough, and the number of screws 6 is increased, for example, as shown , two per track 7.
  • Such an arrangement can be interesting in regions with little wind.
  • FIG. 8 differs from that of FIGS. 1 to 5 in two aspects: on the one hand, the washers 5 are flat and welded to the rod of the screws 6. On the other hand, these screws comprise, au- above the washer 5, an extension 20 which passes through the sealing coating and which projects slightly above it. This extension is threaded and receives by screwing the tapped lower bushing 21 of a support 22. The upper part 23 of this support is threaded, and on it is screwed, at an adjustable height, a plate 24. A rail 25 is fixed on all of the plates 24 of the same row, and an over-roof 26 having essentially an esthetic, non-watertight purpose, is fixed on the beams 25.
  • the sealing of the covering is obtained by gluing or welding the covering 18 on the elements 4 and 5, all around the extension 20 of each screw 6.
  • the support members 5 can be integral with the connecting members 4 or even integral with them, in particular when the members 4 are made of coated metal.
