Description

METAL BUILDING STRUCTURE - - ^'

The present invention relates to a metal building structure comprising load-bearing elements and horizontal purlins made up of profiles formed by cold profiling of a continuous metal strip. Metallic building structures are already known. comprising load-bearing elements which consist of cold profiles. However, the known assembly devices for these cold sections are difficult to implement and considerably increase the final structure. The present invention seeks to overcome these drawbacks by providing a light metal building structure, comprising cold sections, the assembly of which is particularly simple.

The structure of the building according to the invention comprises elongated load-bearing elements, in particular vertical posts for supporting the frame and the rafters, and horizontal elongate purlins also, shaped by cold profiling, assembly means for these various elements together, and means for fixing the structure to the ground.

According to the present invention, the carrier elements consist of at least two similar metal alloy profiles shaped by cold profiling and each comprising a flat core and two flat wings perpendicular to the core and both located on the same side of the core to which they are connected by fold lines at a right angle, the two profiles being assembled back to back, that is to say their two cores substantially contiguous. Thus, starting from two profiles having a section substantially in the shape of a "U" and obtained by cold profiling from a continuous metal strip, one finally obtains an "I" profile.

In addition, according to the invention, the two profiles are assembled back to back with the interposition of assembly plates placed in a spacer allowing S both to rigidly assemble the profiles, and to assemble the load-bearing elements.

FEU3LLΞ DE RΞ ..-? L_ACSMεNT - ^O M ^P I ^" to other parts of the structure (other load-bearing elements, purlins, etc.) and to the ground.

According to a preferred embodiment of the invention, the cores of the two profiles are not directly in contact, but located at a distance equal to the thickness of the assembly plates from one another, each of the two cores being in direct contact with the assembly plates interposed therebetween.

Advantageously, it will be noted that the assembly plates therefore form an integral part of the supporting elements and that there is an empty space between the profiles, at the places where no plate has been interposed.

The same assembly plate can be part of one, two, or three load-bearing elements which it then rigidly assembles with each other or with other parts of the building or structure:

This arrangement makes it particularly easy to assemble building structures according to the invention because, on the one hand, the load-bearing elements comprise, in advance in the form of these assembly plates, the devices for assembly necessary for the construction - of said structure, and, on the other hand, that these assembly plates can be located indifferently in any suitable location of the load-bearing elements, which allows a continuous adjustment of the position of the assembly along said carrier element.

In addition, the building structure according to the invention is light, aesthetic, due to the fact that the assembly plates are mostly hidden by _, the profiles which surround them, and easy to implement, all the profiled elements. cold and the plates being standardized and arriving directly from the producer. The profiles and assembly plates are preferably fixed with bolts and advantageously, for this purpose, corresponding holes are provided pre-drilled in the profiles and plates. In addition, according to the invention, it is provided that each of the horizontal purlins consists of a metal section obtained by cold profiling ε comprising a flat core, two flat wings perpendicular to this core, extending on either side of the web, connecting webs between the wings and the web stretching on the same side of the web, each web being connected to the wing corresponding to it by means of an intermediate strip which extends substantially parallel to said core, each wing being provided at its free end with a flap to which it is connected by an intermediate tab which extends substantially parallel to the core.

A profile is thus obtained, the section of which is substantially in the form of an "I" having exceptional characteristics of resistance to bending and to torsion compared to the profiles of the prior art thanks to the bands and intermediate tabs. substantially parallel to the core.

The invention will now be described, by way of nonlimiting exemplary embodiment, with reference to the appended drawings, in which:

- Figure 1 is a partial schematic view of an embodiment of a building structure according to the invention.

- Figure 2 is a cross-sectional view of a load-bearing building structure according to the invention.

- Figure 3 is a cross-sectional view of a horizontal breakdown of the building structure according to the invention.

- Figures 4a, 4b, 4c, 4d are plan views of assembly plates of load-bearing building structure elements according to the invention.

- Figure 5 is a plan view illustrating the method of assembling via the assembly plates of the horizontal purlins to the load-bearing elements of the building structure according to the invention. - Figure 6 is a perspective view illustrating the method of fixing, via the assembly plates, of the building structure according to the invention to the ground.

The building structure according to the invention represented in FIG. 1 comprises gantries made up of load-bearing elements 100, 102, the reference 100 designating the vertical posts and the reference 102 designating the rafters, horizontal purlins 110 and 112 making it possible in particular to secure the various gantries between them, of flat assembly plates 78, realizing the rigid assembly between two rafters 102 and a post 100, or between a plate 100 and a rafters 102, and / or between a carrying element 100 or 102 ^" and a purlin horizontal 110 or 112, or between the structure according to the invention and the ground.

The elements forming the roof and the walls are directly fixed to the horizontal purlins, and to the load-bearing elements if necessary.

It is appropriate to provide stiffening flats 90 associated rigidly and perpendicular to the assembly plates 78, fixed to each of the supporting elements. ^* -. teurs 100 or 102 by fixing means 92, preferably the bolts.

Preferably, each of these flats extends beyond the assembly plate and is folded at its edge so that the projecting part of the flat is parallel to the carrier element to which it must be fixed. The ^' fixing means 92 are ^' arranged on this projecting part of the flat.

In Figure 2, there is shown a carrier element designated as a whole by the reference 44, particularly intended for the constitution of building structures according to the invention and which consists of an assembly of two identical sections 46 and 48 and assembly plates 78 as will now be explained.

WIPO Each of the sections 46, 48 has substantially the shape of a "U" and has a core 50, 52, flanked by two wings 54, 56, 58, 60, which extend substantially perpendicular to the core 50, 52, and on the same side thereof and are connected thereto along fold lines 55, 57, 59, 61.

The core 50, 52 has two stiffening ribs 62, 64, 66, 68, which extend in the direction of its length. It is understood that these ribs have an optional character and that their number may vary depending on the

10 needs.

The wings 54, 56, 58 and 60 are provided with flaps 70, 72, 74 and 76 folded inwards at an acute angle, preferably close to 45 °.

At least one assembly plate 78 is interposed in

15 spacer between the cores 50 and 52 so that the core 50 is in contact with one of the exterior surfaces of the assembly plate 78, the core 52 being in contact with the other exterior surface of this plate. Thus, the distance separating the two cores 50 and 52 is equal to the thickness-

20 of the assembly plate 78 which has been interposed therebetween. In this way, the variation of the thickness of the plates 78 results in the variation of the total thickness of the carrier elements, which allows direct control to be exercised in a simple manner over this quantity.

25. Advantageously, mounting holes for assembly bolts between the profiles and the plates are pre-drilled in the profiles and in the corresponding parts of the assembly plates, these holes being arranged in one or more lines parallel to the longitu-

30 dinal des -profiles. Advantageously, provision will be made for two rows of holes arranged on parallel lines and equidistant from the axis of the profile.

The shape of the support element as described above allows ^" to obtain an exceptional rigidity with

35 cold spun and therefore for a very low weight. According to a preferred embodiment of the invention, the core has a width varying from 300,500 milli¬ meters, the wings have a width of 70 to 100 milli¬ meters, the profile is obtained from a strip metal 3 to 5 millimeters thick, the assembly plates have a thickness of 5 to 10 millimeters, the stiffening flats of the plates have a width of 100 to 200 millimeters, the span (distance between posts) is 16 to 20 meters. The horizontal failure shown in FIG. 3 is obtained by cold profiling of a continuous metal strip and has, in its final form, a core 22 as well as two wings 24 and 26 perpendicular to the core 22 and extending on either side of the core and connected to the latter by fold lines. In particular, connection webs 28 and 30 are provided between the wings 24 and 26 and the web 22, each web 28 (30) being connected on the one hand to the web 22 by a fold line 29 (31 ) at an obtuse angle, preferably around 135 ^e , and on the other hand to the corresponding wing 24 (26) by means of an intermediate strip 32 (34) which extends parallel to the core 22 , so that the resulting folding angle between the wing 24 (26) and the web 28 (30) is an acute angle, preferably close to 45 °. In addition, each wing 24 (26) is provided at its free end with a flap 36 (38) to which it is connected by an intermediate tongue 40 (42) which extends substantially parallel to the core. 22, so that ^' the flap 36 (38) and the wing 24 (26) form an acute angle between them, preferably close to 45 ^β .

It will be noted that the configuration of the profile gives the latter excellent properties of resistance to bending and torsion, at least equal to that of a standard profile in "I" _y while being of a lighter weight. Figure 4a shows a flat assembly plate -. 78 making it possible to assemble three load-bearing elements as shown in FIG. 1 and 2 between them, in particular, a post and two rafters. This assembly plate, flat, has three flat parts 84, 86, 88 pre-drilled integral and making respective angles © C 1 << 2 3 between them. The profiles of the rafters are fixed to the parts 84 and 88, and the profiles of the post to the part 86. The stiffening flats 90 have also been shown, which in this case allow each of the rafters to be fixed directly and in another plane.

Figures 4b, 4c, 4d show a flat assembly plate 78 for assembling two load-bearing elements as shown in Figure 1 and 2 between them, in particular, two rafters for Figures 4b and 4d, a post and a crossbowman in figure 4c. These plates are produced in two parts 84 and 86 pre-drilled which form an angle σ-s. one in relation to the other.

Each of the parts 84 and 86 allows the assembly of the profiles of each of the carrier elements considered; the stiffening flats 90 suitable for each case solida¬ risent directly and in another plane the two load-bearing elements.

FIG. 5 represents a planar assembly plate 78 extended transversely to a support element 100, 102 as shown in FIG. 1 and 2, of which it is a part and which comprises a planar part 84 pre-drilled to which the profiles are assembled, and a projecting planar part 85 pre-drilled in the same plane as the part 84, but which protrudes outside and on the side of the carrier element 100 or 102.

FIG. 5 also illustrates a method of assembling at least one purlin 110, 112 as shown in FIG. 1 and 3 to the protruding part 85. At least one bracket 87 is rigidly fixed to the protruding part 85, preferably by of

WIPO bolts and purlin 110, 112. Said purlin can be fixed in the middle, or S at one end or at any other place, inside or outside, at square 87. A reinforcement plate 89, having in section substantially the shape of a "U" can be inserted inside the purlin 110, 112 and fixed to it by the fixing means, which are preferably bolts, which secure the bracket 87, the purlin 110, 112 and the reinforcement plate 89. The reinforcement plate 89 can be assembled on the outside of the purlin 110, 112. The same assembly plate 78 can be used to assemble two horizontal purlins end to end end using two brackets fixed to the protruding part 85. FIG. 4d represents a planar assembly plate as shown in FIG. 4b and which has a protruding part 85 intended to assemble one or more horizontal purlins 110, 112 as illustrated in figure 5.

FIG. 6 represents an assembly plate 78 making it possible to fix the building structure according to the invention to the ground. This plate comprises a flat part 84 to which are assembled the lower ends of two sections of a post 100 as shown in FIGS. 1 and 2 and another flat part 83, perpendicular to the part 84, rigidly assembled on the ground, of preferably by bolts which fix it to a reinforced concrete support. The thickness of the part 83 may be different, preferably less, than that of the part 84.

As a variant, the horizontal purlins can be assembled directly at the top of the posts 100, and, in the middle of the profile core via brackets and by the fixing bolts of the profiles and assembly plates. These sand plates and the other breakdowns make it possible to secure the various gantries together, preferably parallel to each other. It also provides r ^' aidisseurs of tubular- elongated shape, connecting the different gantries and their carrier elements together, especially in directions not parallel to the assembly plates, or. the upper horizontal purlins 112 at the lower parts of the rafters 102. These stiffeners can also be fixed to the assembly plates 78; this makes it possible to stiffen the entire structure according to the invention, and, in particular, to avoid the spillage of the various gantries which constitute the structure.
