Description

Dispositif d'assemblage pour la réalisation d'armatures métalliques. Assembly device for producing metal frames.
La présente invention concerne un dispositif d'assemblage pour la réalisation d'armatures métalliques, et plus particu¬ lièrement un profilé métallique adapté à l'assemblage de poutrelles utilisées dans la construction de parois d'isola- tion ou de structures portantes, notamment pour les plafonds de locaux d'habitation, commerciaux ou industriels.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.
On sait que les structures métalliques telles que les charpentes ou supports de faux plafonds présentent générale¬ ment une médiocre résistance au feu, et il est donc nécessaire de les protéger pour obtenir une sécurité satisfaisante. D'autre part, de telles structures peuvent aussi être utili¬ sées pour supporter des parois d'isolation phonique ou thermique, incorporées par exemple dans les planchers eu les plafonds. Les impératifs de l'isolation et de la sécurité ne sont pas cependant facilement compatibles avec les caractéris¬ tiques mécaniques des structures, et on a souvent recours a des dispositifs complexes de fixation sur les structures portantes, qui limitent en outre la qualité esthétique de la réalisation. Le modèle d'utilité DE-U-91.16436 décrit l'assemblage de profiles disposes symétriquement et relies deux a deux par a^ moins un élément plan présentant un bord ayant la forme d'une fourche a trois branches, dont la branche centrale est plus longue et susceptible de s'engager dans un alvéole ouvert a bords rentrants prévu dans chaque profile.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.
Un dispositif d'assemblage de profiles au moyen d'une agrafe métallique et d'une équerre ou d'une coulisse est décrit dans le brevet GB-A-2.029.492. Dans les dispositifs de ce type, il est nécessaire que les profiles possèdent au mojrs un alvéole ouvert.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.
Le brevet FR-A-2.705.708 décrit un dispositif d'isolatior phonique de bâtiment comprenant une poutre porteuse du type IPN dont l'aile de fixation est enveloppée par une bande isolante maintenue par un profile de fixation. Cependant le montage et la mise en place de ces poutres se font de manière classique.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.
. La présente invention a pour objet un dispositif permet¬ tant l'assemblage de structures métalliques légères, en procu- rant à la fois une bonne sécurité contre le feu et une bonne isolation acoustique et/ou thermique. Les structures de ce type trouvent tout particulièrement leur application dans le domaine de la réalisation de parois telles que plafonds, cloisons, planchers hauts, doublages de bardages métalliques, et en particulier de plafonds d'isolation phonique et thermique, tant à la construction que lors d'opérations de rénovation de locaux existants. De plus, dans le cas de la rénovation et de l'isolation de plafonds de locaux existants, le dispositif de l'invention permet le recouvrement de surfaces de portée importante ou de formes non planes, sans requérir la présence de piliers ou supports intermédiaires.. 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.
Le dispositif d'assemblage de l'invention permet de réaliser des structures métalliques légères adaptées pour que l'on puisse y fixer aisément des panneaux et éléments d'isola- tion et/ou de décoration.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.
Le dispositif conforme à la présente invention comprend essentiellement deux profilés métalliques identiques, opposés et parallèles, reliés l'un à l'autre par au moins un élément central plan, chaque profilé comportant, de part et d'autrre de l'élément central plan, au moins un premier alvéole ouvert, s'ouvrant vers l'extérieur perpendiculairement au plan de l'élément central, et au moins un deuxième alvéole ouvert, chacun des alvéoles comportant un pli de bordure sur l'un des côtés de l'ouverture. De préférence, chaque profilé est symétrique par rapport au plan de l'élément central, et comporte ainsi deux alvéoles ouverts vers l'extérieur, perpendiculairement au plan de l'élément central, et deux alvéoles ouverts disposés de part et d'autre de ce plan, ceux du premier profilé faisant face à ceux du deuxième profilé.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.
De préférence, le deuxième alvéole ouvert s'ouvre parallèlement au plan de l'élément central, de telle sorte que le deuxième alvéole du premier profile soit oriente face au deuxième alvéole du deuxième profilePreferably, 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
Suivant une forme de réalisation, les deux profiles métalliques et l'élément central plan forment un seul élément homogène.According to one embodiment, the two metal profiles and the central planar element form a single homogeneous element.
Suivant une autre forme de réalisation conforme à la présente invention, l'élément central plan est encastré dans au moins une feuillure prévue dans chacun des deux profiles métalliques . II peut être avantageux, conformément a l'invention, de prévoir que chaque profile comporte une double rangée d'al¬ véoles disposes symétriquement par rapport au plan moyen du profile, de manière à présenter au moins un alvéole ouvert oriente vers l'extérieur du chant du profile, c'est-a-dire dans une direction opposée a l'autre profile.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.
D'autre part, le dispositif peut être complète par un profile complémentaire, comprrenant une rangée d'alvéoles identiques a ceux du profilé de base, et susceptible de lui être rattache par un simple profile en U. Suivant encore une autre forme de réalisation conforme a l'invention, l'élément plan central comporte des plis de bordure sur chacun de ses bords longitudinaux, formant ainsi une poutre a section en H, chacun des deux profiles métalli¬ ques étant constitue de deux sous-elements identiques, dispo- ses en opposition, et venant se fixer sur chacun des plis de bordure de l'élément central.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.
Dans une variante simple de mise en oeuvre de l'invention adaptée aux structure nécessitant une certaine rigidité et une bonne résistance mécanique, l'élément central peut être constitué par un caisson creux.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.
Les deux profiles métalliques et l'élément central plan constituent le profile de base, et on peut réaliser des armatures métalliques légères en reliant les uns aux autres deux ou plusieurs profilés de base, au moyen d'éléments de liaison et d'agrafes métalliques.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.
Les alvéoles ouverts sont prévus pour recevoir les éléments de liaison constitues par des equerres ou des corniè¬ res maintenus en place au moyen d'agrafes métalliques flexi- bles bloquées à l'intérieur des alvéoles et retenues par le pli de bordure de chaque alvéole. Les alvéoles ouverts peuvent aussi recevoir des accessoires maintenus en place par les mêmes agrafes métalliques. Ainsi, il est possible, confor- mément à l'invention, de fixer une coiffe de protection contre le feu sur ou sous le profilé de base.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.
Suivant une variante de réalisation conforme à l'inven¬ tion, il est possible d'assembler deux profilés de base, par assemblage orthogonal ou linéaire, pour former une armature. L'assemblage orthogonal est obtenu en utilisant des équerres dont une branche est introduite dans l'extrémité de l'alvéole extérieur d'un premier profilé, et l'autre branche dans l'alvéole extérieur d'un deuxième profilé, chaque branche étant bloquée dans les alvéoles par au moins une agrafe métallique. L'assemblage linéaire ou bout à bout de deux profilés de base peut se faire au moyen de coulisses, et de préférence deux coulisses insérées dans les alvéoles inté¬ rieurs, de part et d'autre de l'élément central. Le blocage des coulisses en position se fait également au moyen des mêmes agrafes métalliques.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.
Conformément à une variante de réalisation conforme à la présente invention, on peut réaliser un assemblage angulaire de deux profilés de base suivant un angle quelconque au moyen d'au moins deux compas, l'une des branches du compas étant insérée dans l'alvéole d'un premier profilé, l'autre branche dans l'alvéole d'un deuxième profilé. Ainsi, les deux compas n'étant pas coaxiaux, l'angle formé par les deux profilés est fixé dès- que les branches des compas sont bloquées dans les alvéoles et ne peuvent plus coulisser. Bien entendu, les profilés, coiffes de protection et pièces d'assemblage peuvent être disposés en position verticale pour réaliser des doublages de cloisons de sépara¬ tion de locaux ou de bardages métalliques.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.

Comme le montre la Figure 1, le dispositif conforme à la présente invention est constitué par un profilé de base comprenant deux éléments de profilés (1) et (!') identiques, WAs shown in FIG. 1, the device according to the present invention consists of a base profile comprising two identical profile elements (1) and (! '), W
disposés parallèlement et en opposition, reliés par un voile central (2) plan. Chacun des éléments de profilé (1) et (1') comprend deux alvéoles (3a) et (3b) ouverts vers l'extérieur, symétriques par rapport au plan (2), l'ouverture étant orien- tée perpendiculairement au plan (2), et l'alvéole comportant un pli de bordure, (4a) et (4b) respectivement, sur l'un des côtés de l'ouverture. La fonction de ce pli de bordure sera expliquée en détail plus loin.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.
Les éléments de profilé (1) et (1') comportent encore deux alvéoles intérieurs ouverts (5a) et (5b), dont les ouver¬ tures sont orientées deux à deux face à face. Ces alvéoles (5a) et (5b) comportent également un pli de bordure, (6a) et (6b) respectivement, sur l'un des côtés de l'ouverture.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.
L'assemblage des profilés est réalisé comme représenté sur la Figure 2, montrant deux profilés de base assemblés perpendiculairement au moyen d' équerres (7) maintenues dans la feuillure formée par les alvéoles (3) au moyen d'agrafes métalliques (8) en acier ressort. Comme le montre la Figure 2, l'équerre (7) est plaquée contre le côté de l'alvéole (3) ne comportant pas le pli de bordure, tandis que l'agrafe métalli¬ que (8) est retenue dans l'alvéole par le pli de bordure (4) .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).
La rigidité de l'ensemble est assurée par un gousset de triangulation (9) logé dans la deuxième feuillure formée par les alvéoles extérieurs (3') du deuxième élément de profilé (1') .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').
Comme le montre la Figure 3, le profilé de l'invention, comprenant les deux éléments de profilés (1) et (1') et le voile central (2) forme une poutrelle dont les ailes servent de support et d'appui pour des panneaux d'isolation (10), par exemple des panneaux d'isolation acoustique. Il est nécessaire de protéger le profilé contre le feu en cas d'incendie, et cette protection est obtenue par une coiffe (11) fixée sur l'élément de profilé inférieur (1') au moyen de deux lames ressorts (12a) et (12b) maintenues dans les alvéoles exté- rieurs (3) au moyen d'une simple agrafe métallique (non repré¬ sentée) identique à l'agrafe (8) , qui bloque la lame ressort contre le bord de l'alvéole (3) dépourvu de pli de bordure. La coiffe (11) est mise en place par simple pression, pour écar- ter les lames (12) dont les bords viennent prendre appui contre les épaulements (13) prévus sur les côtés internes de la coiffe. Cette coiffe (11) est réalisée en un matériau résistant au feu, par exemple en céramique, plâtre renforcé ou bois ignifugé.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.
Le cas échéant, les lames ressorts (12a) et (12b) peuvent être bloquées au moyen de deux vis traversant la coiffe (11) de protection au niveau des axes a et a ' indiqués sur la Figure 3. L'espace séparant l'intérieur de la coiffe (11) de la sous-face du profilé constituant la poutrelle améliore l'iso¬ lation en évitant tout contact direct entre la coiffe et le profilé. Le cas échéant, cet espace peut être utilisé pour y loger divers accessoires tels que, par exemple, des gaines de câblages électriques destinés à alimenter un système d'éclai¬ rage.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.
La Figure 4 montre l'extrémité de la poutrelle (1) de la Figure 3 fixée à une deuxième poutrelle (14) identique à la première, mais disposée perpendiculairement, la liaison des deux poutrelles se faisant comme représenté sur la Figure 2 au moyen d'équerres (7) et d'agrafes métalliques (8) de blocage logés dans les alvéoles extérieurs (3) des profilés. L'autre extrémité de la poutrelle (1) est fixée de la même façon à une deuxième poutrelle (14), chacune de ces deux poutrelles (14) formant une lisse fixée au mur porteur (15), par boulonnage sur un socle (16) .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 ).
L'épaisseur du socle (16) est égale à la moitié de la largeur de la coiffe de protection (11) qui est fixée sur la base de la poutrelle (14) de la même manière que la coiffe de protection représentée sur la Figure 3. Ainsi, par construc¬ tion, cette coiffe de protection de la poutrelle constituant la lisse porteuse se trouve en bordure de plafond, contre la paroi du mur.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.
La mise en place s'effectue de la manière suivante : les deux lisses porteuses (14) sont tout d'abord fixées sur les deux murs opposés (15), puis plusieurs poutrelles (1) sont disposées parallèlement, perpendiculairement aux lisses (14), la jonction entre les poutrelles (1) et le bord des lisses (14) se faisant par les équerres (7) dont l'une des branche est fixée au moyen des agrafes (8) dans l'extrémité des alvéo¬ les (3) des profiles formant les poutrelles (1), tandis que l'autre branche prend appui sur la face inférieure de l'alvéole extérieur du profilé constituant la lisses (14) . Le blocage de cette branche de l'équerre n'est effectué que dans un deuxième temps, afin de permettre un positionnement appro¬ prie des poutrelles, et de profiter un déplacement possible des poutrelles (1) par rapport à la lisse (14) pour faciliter la mise en place des panneaux d'isolation. Le blocage de l'ensemble par les agrafes (8) agissant sur la deuxième bran¬ che de chaque équerre est effectue après mise en place de chaque panneau prenant appui sur les ailes inférieures des poutrelles (1) . La Figure 5 représente une variante du dispositif de 1 ' invention où le profilé de base est équipe de deux cornières complémentaires (17) disposés symétriquement et bloques dans les alvéoles intérieurs (5) au moyen d'une agrafe métallique (8) . Ces cornières présentent une face d'appui (18) sur laquelle repose un panneau d'isolation thermique (19), tandis qu'un panneau d'isolation phonique (20) prend appui sur les ailes inférieures du profile.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.
Comme dans l'exemple représente sur la Figure 3, la face inférieure du profile est protégée par une coiffe de protec- tion (11) maintenue par deux lames ressorts.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.
On peut ainsi disposer en partie supérieure d'un panneau (19) de 80 mm d'épaisseur de laine d'isolation thermique, et en partie inférieure d'un panneau de 50 mm de produit d'isolation phonique. La Figure 6 représente un exemple de réalisation tout particulièrement adapte à l'isolation de combles, c'est-a-dire de locaux dont le plafond présente une section polygonale, comportant un plan horizontal encadre par deux plans inclinés.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.
L'articulation (21) représentée sur cette figure permet d'adapter le profilé à la forme du plafond à isoler. L'articulation est constituée par deux compas (21a) et (21b) dont chacune des deux branches présente une languette (22) destinée a faciliter la mise en place dans l'alvéole intérieur (5) du profilé (1) . Un compas est placé dans chacun des deux alvéoles intérieurs (5) de l'élément de profile supérieur, de part et d'autre du voile central (2), tandis que deux autres compas sont placés dans les alvéoles intérieurs de l'élément de profile inférieur.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.
Les branches de chaque compas sont bloquées dans les alvéoles intérieurs au moyen d'agrafes métalliques (8) . Une fois les agrafes mises en place, on voit que les compas sont bloqués dans une position angulaire fixe, qui ne peut varier en raison du décalage des axes d'articulation des compas lies à l'élément de profilé supérieur et à l'élément de profilés inférieur, respectivement.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.
La Figure 7 montre l'utilisation de coulisses (23) insérées dans les alvéoles intérieurs (5) opposes. Ces coulisses (23) comportent sur leurs bords une languette (24) destinée a coopérer avec des agrafes métalliques (8) pour assurer le blocage dans les alvéoles (5) . On dispose ainsi deux coulisses, une de part et d'autre du voile central (2), dont l'une des extrémités est engagée dans un premier profile et l'autre extrémité dans l'alvéole intérieur d'un deuxième profile dispose en bout.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. .
On peut ainsi assembler bout a bout deux profiles conformes a la présente invention. A titre d'exemple, deux profilés de deux mètres de longueur peuvent être ainsi assembles pour constituer une poutrelle de quatre mètres de longueur dont les propriétés mécaniques sont proches de celles d'un profilé unique de même longueur, maigre la rupture de matière, grâce à l'action de solidarisation des coulisses bloquées dans les alvéoles intérieurs. De telles coulisses peuvent aussi être utilisées comme membrures de renforcement, non seulement pour assembler des profilés bout à bout, mais aussi pour renforcer les caractéristiques mécaniques d'un profile, en solidarisant l'un des bords de la coulisse avec l'une des têtes de la poutrelle, tandis que l'autre bord est maintenu en compression a l'intérieur de l'alvéole de la tête opposée de la poutrelle.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.
Suivant la variante représentée sur la Figure 8, le profilé de base de l'invention est constitué de cinq éléments, c'est-à-dire que chacun des deux éléments de profilé est lui même réalisé en deux parties distinctes identiques disposées symétriquement. Ainsi chaque demi-profilé comporte deux alvéoles ouverts (26) et (27), ainsi qu'un troisième alvéole (28) destiné à assurer la fixation sur les ailes (29) du voile central (30) . La fixation se fait au moyen d'une platine de liaison (31) et des agrafes métalliques (8) identiques à celles utilisées précédemment.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.
On obtient ainsi une forme de profilé, une fois l'assemblage effectué, semblable à celle du profilé de la Figure 1.One thus obtains a shape of profile, once the assembly carried out, similar to that of the profile of Figure 1.
Comme dans les exemples précédents, des accessoires peuvent être insérés dans les alvéoles ouverts où ils sont maintenus en place au moyen d'agrafes métalliques (8) . Ainsi par exemple, on peut fixer une cornière support (32) dans l'alvéole intérieur ouvert (26) pour permettre la mise en place de deux panneaux d'isolation disposés en parallèle, l'un reposant sur la cornière support (32), l'autre sur l'aile inférieure de la poutre. Une coiffe de protection peut être installée de la même manière que dans les exemples précédents.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.
Comme le montre la Figure 9, le profilé de base de la Figure 1, dont on a représenté l'élément de profilé (1) et le voile central (2), est assemblé à un profilé simple (33) par l'intermédiaire de la même équerre (7) et des mêmes agrafes métalliques (8) que précédemment, coopérant avec l'alvéole (34) du profilé (33) identique à l'alvéole (3) .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).
Le profilé (33) comporte seulement les deux rives paral¬ lèles (35) et (36), la première limitant l'alvéole (34) et la seconde servant de support à un matériau de protection (37) ou une plaque de décoration ou d'isolation. L'espace séparant l'alvéole (34) de la rive (36) est suffisant pour que la plaque (37) puisse passer sous le profilé (1) et le masquer entièrement, si on le désire. Dans la variante représentée sur la Figure 10, le profilé (38) comporte un alvéole central fermé (39) formant caisson de raidissement améliorant la rigidité du profilé. Ce profilé comporte encore, de chaque côté du caisson central, deux alvéoles (40) et (41) servant respectivement à l'assemblage de profilés deux à deux au moyen d'équerres et d'agrafes métal¬ liques, comme précédemment, et à recevoir des matériaux d'isolation, après assemblage des profilés. Le profilé représenté sur la Figure 11 reprend la structure de base du profilé de la Figure 1, mais avec une double rangée d'alvéoles disposés symétriquement sur chaque rive. Ainsi, il comporte des alvéoles (42) et (43) identiques aux alvéoles (5) et (3) respectivement, disposés symétrique- ment par rapport au plan de la rive (44) . Dans ce cas, le voile central (2) se prolonge au-delà du plan de rive (44) pour délimiter les deux alvéoles symétriques (42) et (42b) .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).
Un exemple d'assemblage orthogonal de trois profilés identiques à celui de la Figure 11, suivant trois directions, est représenté sur la Figure 12.An example of orthogonal assembly of three profiles identical to that of Figure 11, in three directions, is shown in Figure 12.
La liaison entre les profilés est obtenue comme précé¬ demment, au moyen d'équerres et d'agrafes métalliques logés dans les alvéoles (43) et (42) .The connection between the profiles is obtained as previously, by means of brackets and metal staples housed in the cells (43) and (42).
On voit qu'il est ainsi possible d'assembler directement l'extrémité d'un profilé (b) sur le chant d'un profilé (a), chaque profilé formant une poutrelle, la symétrie des alvéoles permettant de doubler les moyens d'assemblage et d'obtenir une résistance mécanique améliorée de la structure ainsi obtenue. De plus, comme le montre la Figure 12, un troisième profilé, constituant une troisième poutrelle, peut être assemblé au profilé (a) dans une position quelconque, mais de préférence de telle sorte que ses deux alvéoles (42) et (42b) soient en communication avec les alvéoles (43) et (3) respectivement du profilé (b) . On forme ainsi non seulement une structure métallique tridimensionnelle, mais aussi des zones d'assemblage continues permettant de mettre en place des éléments constructifs addi¬ tionnels tels que sous-plafonds, équipements techniques ou panneaux de décoration, ou encore des éléments d'assemblage supplémentaires (tels qu' équerres et agrafes métalliques) destinés à renforcer la rigidité de l'ensemble.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.

1212
(45) comportant deux alvéoles à ouverture perpendiculaire (3c) et (5c) identiques aux alvéoles (3) et (5) respectivement du profilé de base.(45) comprising two cells with perpendicular opening (3c) and (5c) identical to the cells (3) and (5) respectively of the base profile.
Ce profilé complémentaire (45) est fixé au profilé de base par l'intermédiaire de deux profilés en U (46) comportant un pli de bordure (47), s'insérant dans les alvéoles (3) du profilé de base et (3c) du profilé complémentaire où il est bloqué au moyen d'une agrafe métallique du type précédemment décrit. Ce profilé complémentaire, ainsi assemblé au profilé de base, permet de renforcer la rigidité et la résistance méca¬ nique de la structure métallique.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.
Suivant une variante de réalisation, on utilise un profilé en U (48) sans pli de bordure qui est inséré dans les alvéoles (5) du profilé de base et (5c) du profilé complé¬ mentaire. Pour assurer la rigidité du montage, il est préférable d'utiliser deux profilés en U placés dos à dos, comme représenté sur la Figure 13. La fixation est assurée comme précédemment au moyen d'agrafes métalliques. 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.
