Definitions

  • the present invention relates to a self-supporting folded sheet metal profile for a building frame, comprising a pair of wings which are substantially symmetrical to each other and connected by a core having a flat central part, each wing having a sole plate perpendicular to the part central of the core, a first flange folded perpendicular to the sole and provided with a free edge facing the other wing, and a second flange folded perpendicular to the sole and connected to the core by a connection part of blade.
  • the invention also relates to a metal frame building covering comprising parallel purlins or beams formed by profiles as mentioned above, external panels supported by the purlins or smooth, as well as insulating plates disposed between said profiles and supported by them.
  • the invention also relates to a method of mounting such a cover, in which said sections are fixed to metal beams.
  • patent EP-0 110 373 describes a metal frame whose purlins are formed by profiles of the kind specified above. Each of said second flanges of the wings is connected to the central part of the core by a connection part inclined approximately at 45 °.
  • the publication FR-A-2 251 681 describes a light metal support made of sheet metal folded in a double T profile with flat wings, for supporting light insulating panels which are nested between the two wings. Such a light profile is not part of a frame and cannot be used as a purlin.
  • the present invention aims to provide a profile and a roof structure to avoid the drawbacks indicated above, thanks to a profile offering advantages comparable to those of a symmetrical I profile.
  • the invention relates to a profile of the kind indicated above, characterized in that the respective parts of connection between the wings and the central part of the core are substantially parallel and have a spacing between them which corresponds to the spacing between said free edges of the wings and in that at least one of said first flanges is provided with holes for spacer elements arranged to connect two parallel sections.
  • FIG. 4 of patent FR-A-2 151 430 A folded sheet metal profile having core connection parts parallel to each other is illustrated by FIG. 4 of patent FR-A-2 151 430.
  • it is not a self-supporting profile such as than a metal frame beam, but only of a light sheet metal element, belonging to a composite profile and can only support loads if it is rigidly coupled to several other similar elements applied against each other.
  • the so-called omega form of the core is only intended to fit onto a corresponding form of a parallel element.
  • At least one of said second flanges is provided with holes, arranged opposite the holes of the first corresponding flange.
  • the width of said connecting parts can advantageously be greater than or equal to a quarter of the width of the flanges.
  • a building covering according to the invention comprising such profiles is characterized in that the insulating plates are inserted laterally in the profiles between said free edges of the wings, on one side of a profile, and between said connecting parts of the soul on the other side of this profile.
  • the insulating plates have a thickness less than the spacing between said connection parts of a profile, and an edge of an insulating plate lying between said connection parts is held by engagement between one of said parts of connection and a wedging element fixed to the web of the profile.
  • the present invention provides a method characterized in that, after having fixed on the beams a series of said parallel sections forming purlins or rails, an edge of a first insulating plate is engaged between the wings of a first profile, the plate is pivoted around this edge so as to bring the opposite edge of the plate close to a second profile and this edge is engaged between the wings of the second profile, and in which is then fixed exterior roof or facade panels on said profiles.
  • spacers are installed connecting two adjacent profiles after the establishment of the insulating plates between these profiles, said bars being placed on the outside of said plates.
  • the spreader bars can be attached to the edges of the outer wings of the profiles.
  • FIG. 1 represents the transverse profile of a profile made of galvanized sheet metal, folded by rolling, having a general shape approximately in C in which there is a top wing 2, a core 3 and a bottom wing 4.
  • the shape of the profile 1 is symmetrical with respect to a median longitudinal plane 5 perpendicular to the core 3, that is to say that the wings 2 and 4 are symmetrical to one another.
  • Each wing 2, 4 comprises a sole 6 parallel to the plane 5, a first flange 7 perpendicular to the sole 6 and having a free edge 8, and a second flange 9 also perpendicular to the sole 6, that is to say that each wing defines a rectangular channel 10 in which one can accommodate certain accessory elements such as cables or conduits.
  • the core 3 consists of a flat central part 11, perpendicular to the plane 5, and two connection parts 12 and 13 which connect it respectively to the wings 2 and 4.
  • the connection parts 12 and 13 of the profile 1 are folded substantially at right angles to the central part 11 of the core, so that they define between them, on the side called the back of the profile, a recess 14 with a rectangular profile, having a depth A and a width B which is the spacing between the parts 12 and 13.
  • the free edges 8 of the two wings 2 and 4 have a spacing C which is substantially equal to the spacing B.
  • FIG. 2 shows another example of a profile 16 according to the invention, having a core of lesser height, but wings 2 and 4 identical to those of profile 1.
  • the free edges 8 of the wings have a spacing D which corresponds to that of the parts 12 and 13 connecting the wings 2 and 4 to the central part 17 of the core.
  • This allows the profile 16 to be conveniently used to support, on any of its sides, plates 18 having a thickness slightly less than D.
  • these plates are inserted between the connecting parts 12 and 13 and are supported by the part 13 if it is assumed that the section 16 extends horizontally.
  • the plates 18 are inserted between the free edges 8 and can rest on one of them. If the profile 16 is rotated 90 ° in one direction or the other, the plates 18 can be supported by the central part 17 of the core.
  • the wings 2, 4 have the same dimensions in the profiles 1 and 16 shows that it is possible to produce a range of profiles having different heights, but similar wings, which rationalizes both the manufacture of the profiles and the erection of structures with them, as well as the standardization of accessory elements that can be used with these profiles.
  • this condition is not essential and the dimension A can be varied within a range of profiles, in particular to adapt the positions of the center of gravity and the center of torsion, without losing the advantages mentioned above. -above.
  • FIG. 2 Another advantageous aspect of the profiles according to the invention lies in the possibility of providing holes (not shown) for assembly means both in the edges 7 and 9 of the wings as in the central part 11, 17 of the core. .
  • Figure 2 there is indicated in phantom a possible arrangement of distance tubes 35 fixed to the edges 7 and 9 of the upper wing of the profile, by means of end caps 36 of known type, blocked in the ends of the tubes and fixed in holes in flanges 7 and 9.
  • FIG. 3 schematically shows a building such as a hall, comprising a metal frame of conventional shape, made by means of profiles of the type described above.
  • the frame of the building comprises rigid transverse frames formed by beams 21 to 24 connected together by gussets 25 to 27, each of these beams being formed, according to a principle known in the prior art, by two profiles such that 1 arranged back to back and fixed on either side of the gussets.
  • the elements 22 and 23 of the frames support metal purlins 30 carrying cover panels 31.
  • On the elements 21 and 24 are fixed horizontal beams 32 carrying front panels 33.
  • FIG. 4 the main elements of the roof comprising the purlins 30 are seen in greater detail, and the main elements of a facade comprising the healds 32, these purlins and these healds being formed from folded sheet sections of the kind illustrated by Figures 1 and 2.
  • the frames carriers are not shown, in order to clarify the drawing.
  • Rigid thermal insulation plates 34 are incorporated into the roof and are mounted on the lower wings 4 of the purlins 30, according to the principle illustrated in FIG. 2.
  • the purlins 30 are formed by relatively high sections, the core of which has a height greater than twice the thickness of the plates 34. This makes it possible to have, above these plates, spacer tubes 35 which are fixed by central screws in holes made at mid-height of the core of each purlin 30, the end of each tube being in abutment against the profile in a known manner, by means of a plastic end piece 36.
  • vertical insulation plates 37 are mounted between the rails 32 , as well as vertical distance tubes 38 fixed in the same way as the tubes 35. The tubes 35 and 38 also ensure the retention of the plates 34 and 37, in particular against lifting by the effect of the wind.
  • This construction and the particular shape of the sections forming the purlins 30 allow a particularly advantageous method of mounting the roof of the building from the top. Indeed, once the purlins 30 are fixed on the beams 22 and 23 of the transverse frames, it is possible to put in place the other elements of the roof from walkways placed directly on the purlins.
  • For mounting the insulation plates 34 insert the lower edge 34a of each plate between the free edges of the wings 2 and 4 of the first purlin 30, then lower the other edge 34b of the plate until 'it rests on the lower wing 4 of the second breakdown 30. It is then possible to place the distance tubes 35 above the row of plates 34 thus formed, then the cover panels 31 which may be of n any common type. Then, we practice the same between the following two breakdowns.
  • the establishment of the plates 34 is very easy and rapid thanks to the fact that they rest directly on the wings of the purlins 30, without it being necessary to attach thereto additional supports for the plates.
  • the same method can be used to make the facade from the outside.
  • the establishment of the insulation plates 37 can also be done from the inside, while benefiting from the protection of the roof.
