Definitions

  • the present invention relates to a self-supporting roof, in particular for industrial buildings, formed of modular elements of large span.
  • the present invention improves the roofing element of the above type, by using an interior wall that is also self-supporting and by rigidly connecting it to the exterior wall by means of said arches, so as to take advantage of the inherent rigidity of the inner wall to increase the bending moment of the roof element.
  • the interior wall in addition to its conventional function of supporting the insulating layer, contributes to the resistance of the roofing element.
  • the poles have their ends fixed to compression profiles arranged longitudinally with respect to the walls. This increases the compressive strength at the ends of the walls and strengthens the transmission of forces between the outer and inner walls, therefore the overall strength of the roofing element.
  • the poles are of rectangular section tube that is filled with a heat insulator, for example a plastic foam, to prevent them from forming a thermal bridge.
  • a heat insulator for example a plastic foam
  • the arches are formed by spaced sections fixed respectively to the inner and outer walls, between which are fixed at intervals spacer pieces.
  • the roofing elements according to the invention can have different shapes: the walls can thus be formed from curved ribbed sheets, or alternatively the walls can have a trapezoidal shape.
  • the outer wall will advantageously comprise two identical elements arranged symmetrically, fixed to each other directly or by means of a skylight, and the inner wall will comprise two elements identical to the aforementioned elements.
  • FIG. 1 shows two elements 1 of a freestanding roof for an industrial building.
  • Each element has in section a substantially semi-circular shape, with a width which can be around 2 meters, and can have a length of up to 30 meters.
  • the elements are supported at their ends by supports symbolized in A, which can be constituted by the front walls of the building.
  • Each element comprises an outer wall 2 and an inner wall 3 curved identically and with the same mechanical strength. Between these walls are arranged, at regular intervals in the longitudinal direction, transverse arches matching the shape of the walls (see FIG. 5 for this arrangement) and one of which is shown in section in FIG. 2a.
  • the arch 4 of Figure 2a is a square section tube which is fixed, on the one hand to the outer wall 2 and, on the other hand, to the inner wall 3 by any suitable means, preferably by auto screws -drills and self-tapping symbolized by the mixed lines.
  • thermal insulator 5 for example glass wool.
  • the hoops 4 are themselves filled with a thermal insulator 6, for example a polyurethane foam formed in place, in order to prevent the hoops 4 from forming thermal bridges.
  • thermal insulator 6 for example a polyurethane foam formed in place
  • FIG. 2b shows a variant with respect to the embodiment of FIG. 2a, in which irons 10, 11 having spread wings are fixed respectively to the walls 2 and 3, and between the irons 10 and 11 are placed at intervals.
  • regular pads 12 of thermally insulating rigid material, for example wood or rigid plastic.
  • the connection between the bars 10 and 11 is ensured by clamping pieces 13, 14 respectively enclosing the pads 12 and connected by blocking a nut 15 on a bolt 16.
  • the walls 2 and 3 are, in the embodiment of Figure 1, made of steel trays, that is to say of ribbed steel sheets. These containers are commercially available and each wall will be formed from one or more of these containers, depending on the required width. If a wall includes several tanks, the connection will be obtained by covering the waves (or ribs) and fixing by screws.
  • longitudinal profiles 17 are provided, housed in the last wave of the outer wall 2, and likewise longitudinal profiles 18 housed in the last wave of the inner wall 3.
  • Each of these compression profiles is placed between two consecutive arches 4 and is fixed by its ends to plates 19 welded to the arches 4.
  • connecting bars 20 Between two adjacent roof elements are arranged connecting bars 20 forming spacers, which are fixed on the exposed ends of the poles 4. Above the connecting bars 20 is placed a watertight ridge 21, and under the bars 20 is a sub-ceiling 22 supported by the upper face of the compression profiles 18. A layer of thermal insulation 23 is placed on the sub-ceiling 22.
  • a simple translucent skylight could also be placed between two adjacent roof elements.
  • the inner wall 3 contributes by its own resistance to the rigidity of the roof, instead of forming a dead weight than the wall exterior must support, as in the prior art mentioned above. This makes it possible to increase the range of an element or, for a given range, to reduce the thickness of the walls.
  • the roof elements 1 are prefabricated in the factory and the only remaining operations to be carried out on the site are the installation of the elements 1 on the supporting walls and the installation of the connecting bars, the ridge, etc. ., between elements 1.
  • FIG. 4 There is shown in Figure 4 a preferred embodiment in which there are provided two compression profiles formed by tubes of square section 25, 26 extending continuously over the entire length of the element roofing ment, instead of being placed between the arches in the waves of the walls, as shown in FIG. 3.
  • all the arches 27 have their ends fixed respectively to the profiles 25 5 26.
  • the profiles 25, 26 are also, like the tubular arch of Figure 2a, filled with a thermal insulation foam formed in place.
  • the hoops also have a different structure from what has been described above. They are each formed of two T sections 28a, 28b fixed respectively to the outer wall and to the inner wall, preferably by means of self-tapping screws, not shown. The sections 28a, 28b are separated and joined at intervals by metal parts 29 welded to the cores of the sections 28a, 28b. Such an embodiment has the advantage of great simplicity of implementation.
  • FIG. 7 shows a roof element designed according to the same principle, but in the form of a trapezoidal wave.
  • the inner wall is made mechanically integral with the outer wall by hoops, not visible, in the general shape of a trapezoid.
  • the outer wall is formed by two half-walls 30 and 31 of identical shape, assembled by wings 35 formed at the ends.
  • the half-walls 30, 31 each have an oblique part forming the slope, extended by parallel parts between them which form the horizontal parts of the roof and which have different lengths a and b.
  • the inner wall is also formed by two half-walls 32 and 33, which have exactly the same shape as the half-walls 30, 31 forming the outer wall, but which are returned with respect to these, the part of length b of the half-wall 32 (or 33) being opposite the part of length a of the half-wall 30 (or 31).
  • connection with the adjacent elements is carried out by bolting the wings 35, and joint covers 36 are placed at the junctions to ensure sealing.
  • FIG. 8 shows a variant in which bars 37 connect the halves of elements, said bars being fixed to the arches, and a translucent skylight 38 covers the space thus formed between the halves of elements.
