Definitions

  • the present invention relates to a self-supporting roof, in particular for industrial buildings, formed of modular elements of large span, in accordance with the preamble of claim 1.
  • FR-A-1 558 925 It is known from FR-A-1 558 925 to use modular roof elements with oblique planes comprising a self-supporting outer shell or wall conferring mechanical resistance to the element, a layer of thermal insulation and an inner wall supporting the insulation layer and carried by the outer wall, the latter being further stiffened by metallic elements, such as "omega" irons welded to the shell.
  • the roof elements are prefabricated in the factory, the work remaining to be done on the site essentially consists of putting the elements in place and assembling them to form the total roof.
  • FR-A-2 147 866 describes a roof of the same type as that of FR-A-1 558 925, specifying that it is composed of longitudinal elements resting on a horizontal structure and each consisting of an inverted V hull, and transverse stiffening frames folded so as to have a geometry congruent to the cross section of the shell.
  • FR-A-1 494 733 describes a self-supporting structural element comprising two ribbed sheets placed face to face and joined together by insulating rods.
  • the roof thus produced can be flat or composed of vaults.
  • DE-A-2 609 405 describes a roofing element in the shape of a gutter, which behaves in a manner similar to that of a box beam subjected to bending and comprising a series of internal stiffeners formed by a single solid profile arranged transversely between the two walls and rigidly linked to the latter.
  • the invention aims precisely to increase the bending moment which can be supported by the roof and to reduce the dead weight to bear while reducing the existence of thermal bridge at the level of the stiffeners between the two inner and outer walls.
  • the section of the modular elements being in the form of an inverted vault
  • the ends of the stiffeners are thus fixed to the compression bars that the stiffeners are constituted by two irons or two spaced apart profiles l 'from each other and each fixed respectively to the inner and outer walls and that bracing pieces are fixed at intervals along each stiffener between said profiles, so as to prevent the formation of a continuous thermal bridge between them this.
  • the roofing elements according to the invention have the shape of a vault, the walls being formed for example of curved ribbed sheets.
  • FIG. 1 shows two elements 1 of a freestanding roof for an industrial building.
  • Each element has in section a substantially semicircular shape open upwards, 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 exterior wall 2 and an interior wall 3 curved in an identical manner and with the same mechanical strength. Between these walls are arranged, at regular intervals in the longitudinal direction, transverse stiffeners conforming to the shape of the walls (see FIG. 5 for this arrangement) and one of which is shown in section in FIG. 2 and in FIG. 6.
  • FIG. 2 There is shown in Figure 2 a variant in which two irons 10, 11 having spread wings form the stiffener 4; they are fixed respectively to the walls 2 and 3, and between the irons 10 and 11 are placed at regular intervals bracing pieces formed by pads 12 of rigid thermally insulating material, for example wood or rigid plastic material.
  • 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 tanks, 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 comprises 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 sections constitute strips which work in compression, since the vault is open upwards.
  • Each profile is placed between two consecutive stiffeners 4 and is fixed by its ends on plates 19 welded to the stiffeners 4.
  • connecting bars 20 Between two adjacent roofing elements are placed connecting bars 20 forming spacers, which are fixed to the exposed ends of the stiffeners 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 longitudinal compression strips 18 opposite. 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 interior 3 contributes by its resistance to the rigidity of the roof, instead of forming dead as the wall exterior must
  • the roof elements 1 are prefabricated in the factory and the only operations remaining to be carried out on the site are the installation of the elements 1 on the support walls and the installation of the connecting bars, the ridge, etc. ., between elements 1.
  • Such a variant reinforces the role of transmission of forces between the walls played by the compression profiles.
  • the sections 25, 26 are moreover filled with a thermal insulation foam formed in place.
  • the stiffeners 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 bracing pieces constituted by metal plates 29 welded to the webs of the sections 28a, 28b. Such an embodiment has the advantage of great simplicity of construction and provides a very satisfactory thermal break between walls, over the entire length of the stiffener 27.
