Description

Assembly device for producing metal frames.

The present invention relates to an assembly device for producing metal reinforcements, and more particularly a metal profile suitable for assembling beams used in the construction of insulation walls or load-bearing structures, in particular for the ceilings of residential, commercial or industrial premises.

It is known that metallic structures such as frames or supports for false ceilings generally have poor fire resistance, and it is therefore necessary to protect them in order to obtain satisfactory security. On the other hand, such structures can also be used to support sound or thermal insulation walls, incorporated for example in floors and ceilings. The requirements of insulation and safety are not however easily compatible with the mechanical characteristics of the structures, and complex fixing devices are often used on the supporting structures, which further limit the aesthetic quality of the production. The utility model DE-U-91.16436 describes the assembly of profiles willing symmetrically and connected in pairs by a _^ least one planar member having an edge having the shape of a fork has three branches, the central branch is long and likely to engage in an open cell with re-entrant edges provided in each profile.

A device for assembling profiles by means of a metal clip and a bracket or a slide is described in patent GB-A-2,029,492. In devices of this type, it is necessary that the profiles at least have an open cell.

The patent FR-A-2,705,708 describes a soundproofing device for a building comprising a carrying beam of the IPN type, the fixing wing of which is enveloped by an insulating strip maintained by a fixing profile. However the mounting and positioning of these beams is done in a conventional manner.

. The subject of the present invention is a device allowing both the assembly of light metal structures, while providing both good fire safety and good acoustic and / or thermal insulation. Structures of this type find their particular application in the field of the production of walls such as ceilings, partitions, high floors, lining of metal cladding, and in particular of sound and thermal insulation ceilings, both during construction and during renovations of existing premises. In addition, in the case of renovating and insulating the ceilings of existing premises, the device of the invention allows the covering of large-area surfaces or non-planar shapes, without requiring the presence of pillars or intermediate supports.

The assembly device of the invention makes it possible to produce light metal structures adapted so that it is easy to fix panels and elements of insulation and / or decoration therein.

The device according to the present invention essentially comprises two identical metal profiles, opposite and parallel, connected to each other by at least one planar central element, each profile comprising, on either side of the planar central element , at least a first open cell, opening towards the outside perpendicular to the plane of the central element, and at least a second open cell, each of the cells having a border fold on one of the sides of the opening . Preferably, each profile is symmetrical with respect to the plane of the central element, and thus comprises two cells open towards the outside, perpendicular to the plane of the central element, and two open cells arranged on either side of this plan, those of the first profile facing those of the second profile.

Preferably, the second open cell opens parallel to the plane of the central element, so that the second cell of the first profile is oriented facing the second cell of the second profile

According to one embodiment, the two metal profiles and the central planar element form a single homogeneous element.

According to another embodiment in accordance with the present invention, the planar central element is embedded in at least one rebate provided in each of the two metal profiles. It may be advantageous, in accordance with the invention, to provide that each profile includes a double row of cells arranged symmetrically with respect to the mean plane of the profile, so as to present at least one open cell oriented towards the outside of the edge of the profile, that is to say in a direction opposite to the other profile.

On the other hand, the device can be completed by a complementary profile, comprising a row of cells identical to those of the base profile, and capable of being attached to it by a simple U-shaped profile. According to yet another conforming embodiment In the invention, the central planar element has border folds on each of its longitudinal edges, thus forming a beam with an H-section, each of the two metal profiles being made up of two identical sub-elements, available in opposition, and coming to be fixed on each of the border folds of the central element.

In a simple variant of implementation of the invention adapted to the structure requiring a certain rigidity and good mechanical strength, the central element can be constituted by a hollow box.

The two metallic profiles and the flat central element constitute the basic profile, and light metallic reinforcements can be produced by connecting to each other two or more basic profiles, by means of metal connecting elements and staples.

The open cells are intended to receive the connecting elements constituted by brackets or angles kept in place by means of flexible metal staples. wheat blocked inside the cells and retained by the border fold of each cell. The open cells can also receive accessories held in place by the same metal clips. Thus, it is possible, in accordance with the invention, to fix a fire protection cap on or under the base profile.

According to an alternative embodiment according to the invention, it is possible to assemble two base sections, by orthogonal or linear assembly, to form a frame. The orthogonal assembly is obtained by using brackets, one branch of which is introduced into the end of the outer cell of a first profile, and the other branch into the outer cell of a second profile, each branch being blocked in the alveoli by at least one metal clip. The linear or end-to-end assembly of two base sections can be done by means of slides, and preferably two slides inserted into the interior cells, on either side of the central element. The locking of the slides in position is also done by means of the same metal clips.

In accordance with an alternative embodiment in accordance with the present invention, it is possible to produce an angular assembly of two base sections at any angle by means of at least two compasses, one of the arms of the compass being inserted in the cell d 'a first profile, the other branch in the cell of a second profile. Thus, the two compasses not being coaxial, the angle formed by the two profiles is fixed as soon as the arms of the compasses are blocked in the cells and cannot slide anymore. Of course, the profiles, protective caps and assembly parts can be arranged in a vertical position to make doublings of partitions separa¬ tion of premises or metal cladding.

As shown in FIG. 1, the device according to the present invention consists of a base profile comprising two identical profile elements (1) and (! '), W

arranged parallel and in opposition, connected by a central central veil (2). Each of the profile elements (1) and (1 ') comprises two cells (3a) and (3b) open towards the outside, symmetrical with respect to the plane (2), the opening being oriented perpendicular to the plane (2 ), and the cell having an edge fold, (4a) and (4b) respectively, on one of the sides of the opening. The function of this border fold will be explained in detail later.

The profile elements (1) and (1 ') further comprise two open internal cells (5a) and (5b), the openings of which are oriented two by two face to face. These cells (5a) and (5b) also have an edge fold, (6a) and (6b) respectively, on one of the sides of the opening.

The profiles are assembled as shown in Figure 2, showing two basic profiles assembled perpendicularly by means of brackets (7) held in the rebate formed by the cells (3) by means of metal clips (8) in spring steel. As shown in Figure 2, the bracket (7) is pressed against the side of the cell (3) not having the edge fold, while the metal clip that (8) is retained in the cell by the border fold (4).

The rigidity of the assembly is ensured by a triangulation gusset (9) housed in the second rebate formed by the external cells (3 ') of the second profile element (1').

As shown in Figure 3, the profile of the invention, comprising the two profile elements (1) and (1 ') and the central web (2) forms a beam whose wings serve as support and support for insulation panels (10), for example sound insulation panels. It is necessary to protect the profile against fire in the event of fire, and this protection is obtained by a cover (11) fixed to the lower profile element (1 ') by means of two leaf springs (12a) and ( 12b) held in the external cells (3) by means of a simple metal clip (not shown) identical to the clip (8), which blocks the leaf spring against the edge of the cell (3) devoid of border fold. The cap (11) is put in place by simple pressure, to spread ter blades (12) whose edges come to bear against the shoulders (13) provided on the inner sides of the cap. This cap (11) is made of a fire-resistant material, for example ceramic, reinforced plaster or fireproof wood.

If necessary, the leaf springs (12a) and (12b) can be locked by means of two screws passing through the protective cap (11) at the axes a and a 'indicated in Figure 3. The space separating the inside the cover (11) of the underside of the profile constituting the beam improves the insulation by avoiding any direct contact between the cover and the profile. If necessary, this space can be used to house various accessories such as, for example, electrical wiring sheaths intended to supply a lighting system.

Figure 4 shows the end of the beam (1) of Figure 3 attached to a second beam (14) identical to the first, but arranged perpendicularly, the connection of the two beams being as shown in Figure 2 by means of 'brackets (7) and metal staples (8) blocking housed in the outer cells (3) of the profiles. The other end of the beam (1) is fixed in the same way to a second beam (14), each of these two beams (14) forming a rail fixed to the load-bearing wall (15), by bolting on a base (16 ).

The thickness of the base (16) is equal to half the width of the protective cap (11) which is fixed to the base of the beam (14) in the same way as the protective cap shown in Figure 3 Thus, by construction, this protective cap for the beam constituting the support rail is located at the edge of the ceiling, against the wall of the wall.

The installation is carried out as follows: the two supporting beams (14) are first of all fixed on the two opposite walls (15), then several beams (1) are arranged parallel, perpendicular to the beams (14) , the junction between the beams (1) and the edge of the rails (14) being made by the brackets (7) one of the branch of which is fixed by means of staples (8) in the end of the cells (3) of the profiles forming the beams (1), while the another branch is supported on the underside of the outer cell of the profile constituting the rails (14). The blocking of this branch of the bracket is carried out only in a second step, in order to allow a suitable positioning of the beams, and to take advantage of a possible displacement of the beams (1) relative to the rail (14) to facilitate the installation of insulation panels. The blocking of the assembly by the clips (8) acting on the second bran¬ che of each bracket is carried out after positioning of each panel bearing on the lower wings of the beams (1). Figure 5 shows a variant of the device of one invention where the base profile is equipped with two complementary angles (17) arranged symmetrically and locked in the inner cells (5) by means of a metal clip (8). These angles have a support face (18) on which a thermal insulation panel (19) rests, while a sound insulation panel (20) is supported on the lower wings of the profile.

As in the example shown in Figure 3, the underside of the profile is protected by a protective cap (11) held by two leaf springs.

It is thus possible to have in the upper part of a panel (19) of 80 mm thickness of thermal insulation wool, and in the lower part of a panel of 50 mm of sound insulation product. Figure 6 shows an exemplary embodiment particularly suitable for insulating attics, that is to say premises whose ceiling has a polygonal section, having a horizontal plane framed by two inclined planes.

The joint (21) shown in this figure allows the profile to be adapted to the shape of the ceiling to be insulated. The articulation consists of two compasses (21a) and (21b), each of the two branches of which has a tongue (22) intended to facilitate positioning in the inner cell (5) of the profile (1). A compass is placed in each of the two inner cells (5) of the upper profile element, on either side of the central veil (2), while two other compasses are placed in the inner cells of the element lower profile.

The arms of each compass are locked in the inner cells by means of metal clips (8). Once the staples are in place, we see that the compasses are locked in a fixed angular position, which cannot vary due to the offset of the hinge pins of the compasses linked to the upper profile element and to the lower profiles, respectively.

Figure 7 shows the use of slides (23) inserted in the opposite interior cells (5). These slides (23) have on their edges a tongue (24) intended to cooperate with metal clips (8) to ensure blocking in the cells (5). There are thus two slides, one on either side of the central web (2), one of the ends of which is engaged in a first profile and the other end in the inner cell of a second profile has at the end. .

It is thus possible to assemble end to end two profiles in accordance with the present invention. For example, two profiles of two meters in length can thus be assembled to form a beam of four meters in length whose mechanical properties are close to those of a single profile of the same length, lean material failure, thanks to the action of securing the slides blocked in the interior cells. Such slides can also be used as reinforcing members, not only to assemble end-to-end profiles, but also to reinforce the mechanical characteristics of a profile, by joining one of the edges of the slide with one of the heads. of the beam, while the other edge is kept in compression inside the cell of the opposite head of the beam.

According to the variant shown in Figure 8, the basic profile of the invention consists of five elements, that is to say that each of the two profile elements is itself produced in two identical distinct parts arranged symmetrically. Thus, each half-profile comprises two open cells (26) and (27), as well as a third cell (28) intended to ensure the fixing on the wings (29) of the central web (30). The fixing is done by means of a connection plate (31) and metal clips (8) identical to those used previously.

One thus obtains a shape of profile, once the assembly carried out, similar to that of the profile of Figure 1.

As in the previous examples, accessories can be inserted into the open cells where they are held in place by means of metal clips (8). Thus, for example, a support angle (32) can be fixed in the open interior cell (26) to allow the installation of two insulation panels arranged in parallel, one resting on the support angle (32), the other on the lower wing of the beam. A protective cap can be installed in the same way as in the previous examples.

As shown in Figure 9, the base profile of Figure 1, of which the profile element (1) and the central web (2) are shown, is assembled to a simple profile (33) by means of the same bracket (7) and the same metal clips (8) as before, cooperating with the cell (34) of the profile (33) identical to the cell (3).

The profile (33) comprises only the two parallel edges (35) and (36), the first limiting the cell (34) and the second serving as a support for a protective material (37) or a decoration plate or insulation. The space separating the cell (34) from the edge (36) is sufficient so that the plate (37) can pass under the profile (1) and completely hide it, if desired. In the variant shown in Figure 10, the profile (38) comprises a closed central cell (39) forming a stiffening box improving the stiffness of the profile. This profile also comprises, on each side of the central box, two cells (40) and (41) respectively serving for the assembly of profiles two by two by means of brackets and metal staples, as before, and to receive insulation materials, after assembly of the profiles. The profile shown in Figure 11 takes the basic structure of the profile of Figure 1, but with a double row of cells arranged symmetrically on each bank. Thus, it comprises cells (42) and (43) identical to the cells (5) and (3) respectively, arranged symmetrically with respect to the plane of the bank (44). In this case, the central web (2) extends beyond the edge plane (44) to delimit the two symmetrical cells (42) and (42b).

An example of orthogonal assembly of three profiles identical to that of Figure 11, in three directions, is shown in Figure 12.

The connection between the profiles is obtained as previously, by means of brackets and metal staples housed in the cells (43) and (42).

We see that it is thus possible to directly assemble the end of a profile (b) on the edge of a profile (a), each profile forming a beam, the symmetry of the cells making it possible to double the means of assembly and to obtain an improved mechanical resistance of the structure thus obtained. In addition, as shown in Figure 12, a third profile, constituting a third beam, can be assembled to the profile (a) in any position, but preferably so that its two cells (42) and (42b) are in communication with the cells (43) and (3) respectively of the profile (b). This not only forms a three-dimensional metal structure, but also continuous assembly zones allowing the installation of additional structural elements such as sub-ceilings, technical equipment or decoration panels, or even additional assembly elements. (such as brackets and metal staples) intended to reinforce the rigidity of the assembly.

Figure 13 shows another example of application of the profile of Figure 11, combined with a complementary profile W

12

(45) comprising two cells with perpendicular opening (3c) and (5c) identical to the cells (3) and (5) respectively of the base profile.

This complementary profile (45) is fixed to the base profile by means of two U-shaped profiles (46) comprising an edge fold (47), fitting into the cells (3) of the base profile and (3c). of the complementary profile where it is locked by means of a metal clip of the type previously described. This complementary profile, thus assembled to the base profile, makes it possible to strengthen the rigidity and mechanical resistance of the metal structure.

According to an alternative embodiment, a U-shaped section (48) is used without a border fold which is inserted into the cells (5) of the base section and (5c) of the complementary section. To ensure rigidity of the assembly, it is preferable to use two U-shaped profiles placed back to back, as shown in Figure 13. The fixing is ensured as before by means of metal staples.
