Ces profilés sont destinés, en particulier, à la constitution de structures porteuses, par exemple des poutres ou planchers de bâtiments ou de véhicules  Profile Field of the Invention The invention relates to extruded light alloy profiles, in particular aluminum alloy, which can be assembled laterally by clipping to one or two other profiles. These profiles are intended, in particular, for the constitution of load-bearing structures, for example beams or floors of buildings or vehicles

Etat de la technique La largeur des profilés utilisés pour des structures porteuses de grande dimension est limitée par la capacité des presses de filage. Il est donc nécessaire d'assembler latéralement plusieurs profilés pour obtenir la surface requise. Cet assemblage peut  STATE OF THE ART The width of the profiles used for large load-bearing structures is limited by the capacity of the spinning presses. It is therefore necessary to assemble several sections laterally to obtain the required surface. This assembly can

se faire de manière mécanique, à l'aide de boulons ou de rivets, ou par soudage.  be done mechanically, using bolts or rivets, or by welding.

Dans les deux cas, cela entraîne un cot de main d'oeuvre élevé et un apport de poids supplémentaire. De plus, toutes les techniques de soudage, avec ou sans métal d'apport, peuvent entraîner une diminution de la résistance mécanique, qu'on ne peut éliminer qu'au prix d'un traitement thermique ultérieur coteux, et parfois  In both cases, this results in a high labor cost and an additional weight gain. In addition, all welding techniques, with or without filler metal, can lead to a reduction in mechanical strength, which can only be eliminated at the cost of a costly subsequent heat treatment, and sometimes

La fixation du bourrelet dans la gorge correspondante se fait par soudage avec métal d'apport. L'invention a pour but de permettre la réalisation de structures porteuses par assemblage latéral de profilés filés en alliage léger, en utilisant une technique d'assemblage simple, rapide et économique à la fois par le temps d'assemblage et l'absence d'investissements importants, tout en assurant une résistance mécanique  European patent EP 0825062 (Peter Maier Leichtbau) describes the lateral assembly of profiles, intended in particular for the manufacture of tail lifts for lorries) comprising on one side face a longitudinal bead in relief, and on the other side face a longitudinal groove intended to receive the bead of the neighboring profile. The bead is fixed in the corresponding groove by welding with filler metal. The invention aims to allow the realization of load-bearing structures by lateral assembly of extruded light alloy profiles, using a simple, rapid and economical assembly technique both by the assembly time and the absence of significant investments, while ensuring mechanical resistance

Objet de l'invention L'invention a pour objet un profilé filé en alliage léger, apte à être assemblé latéralement à un autre profilé, comportant, soit au moins un bourrelet longitudinal en relief, soit au moins une gorge longitudinale de section complémentaire, soit l'un et l'autre, caractérisé en ce que la section du bourrelet et celle de la gorge sont de  OBJECT OF THE INVENTION The subject of the invention is a light alloy extruded profile, able to be assembled laterally to another profile, comprising either at least one longitudinal bead in relief, or at least one longitudinal groove of complementary section, or both, characterized in that the section of the bead and that of the groove are of

Description de l'inventionDescription of the invention

Les profilés filés en alliage léger selon l'invention destinés à des structures porteuses de grande dimension sont généralement des profilés creux multichambres tels que ceux représentés aux figures 1 et 2. Ces profilés comportent, de manière connue, au moins un bourrelet longitudinal (1) servant de pièce mâle pour l'assemblage, soit une gorge (2), également longitudinale, servant de pièce femelle, dans laquelle entre le bourrelet lors de l'assemblage. Les profilés peuvent comporter un ou plusieurs bourrelets (1) et/ou un ou plusieurs gorges (2) selon qu'on veut les assembler à un ou deux autres profilés. On peut souhaiter également, pour les profilés qui ne sont assemblés que d'un seul côté, avoir un ou plusieurs bourrelets (1) ou une ou plusieurs gorges (2) inutilisés pour standardiser la production en évitant la multiplication des  The light alloy extruded profiles according to the invention intended for large load-bearing structures are generally hollow multi-chamber profiles such as those shown in Figures 1 and 2. These profiles comprise, in known manner, at least one longitudinal bead (1) serving as a male part for assembly, or a groove (2), also longitudinal, serving as a female part, in which the bead enters during assembly. The profiles may include one or more beads (1) and / or one or more grooves (2) depending on whether one wants to assemble them to one or two other profiles. One can also wish, for the profiles which are assembled only on one side, to have one or more beads (1) or one or more grooves (2) unused to standardize the production by avoiding the multiplication of

filières, en particulier dans le cas o on assemble des profilés de même section.  dies, in particular in the case where sections of the same section are assembled.

La particularité de l'invention réside dans la forme de la section du bourrelet (1) et celle, complémentaire, de la gorge (2) représentée à la figure 3. En effet, l'une et l'autre présentent une section conique avec une série de crans (3). La pente du cône est comprise, de préférence, entre 5 et 20%. Par ailleurs, le jeu entre le bourrelet (1) et la gorge (2) est négatif, c'est-à-dire que la section conique du bourrelet (1) est légèrement plus large que celle de la gorge (2). Ce jeu négatif est avantageusement  The particularity of the invention lies in the shape of the section of the bead (1) and that, complementary, of the groove (2) shown in Figure 3. Indeed, both have a conical section with a series of notches (3). The slope of the cone is preferably between 5 and 20%. Furthermore, the clearance between the bead (1) and the groove (2) is negative, that is to say that the conical section of the bead (1) is slightly wider than that of the groove (2). This negative game is advantageously

compris entre 2 et 10% de la largeur de la gorge (2).  between 2 and 10% of the width of the groove (2).

Pour assembler deux profilés, on positionne le bourrelet (1) en face de la gorge (2).  To assemble two sections, the bead (1) is positioned opposite the groove (2).

Pour faciliter l'introduction du bourrelet (1) dans la gorge (2), le profilé portant la gorge conique crantée comporte avantageusement une pente d'approche, par exemple une lèvre (4) comme représenté à la figure 3. On amorce la pénétration du bourrelet (1) dans la gorge (2), en exerçant éventuellement une première pression, en calant si nécessaire le profilé mâle. On procède ensuite au clippage final pour obtenir la pénétration complète du bourrelet au fond de la gorge, en jouant sur l'élasticité du  To facilitate the introduction of the bead (1) into the groove (2), the profile carrying the notched conical groove advantageously has an approach slope, for example a lip (4) as shown in FIG. 3. Penetration is initiated of the bead (1) in the groove (2), possibly exerting a first pressure, wedging the male section if necessary. We then proceed to the final clipping to obtain the complete penetration of the bead at the back of the throat, playing on the elasticity of the

métal, en exerçant une pression répartie au droit du bourrelet (1).  metal, by applying a distributed pressure to the right of the bead (1).

Le jeu négatif une fois la pression relâchée et les crans (3) assurent une fixation extrêmement solide des deux profilés grâce au grippage entre les deux surfaces. C'est la précision de la forme obtenue au filage des profilés en alliage d'aluminium et la résistance mécanique élevée obtenue par un traitement à l'état T5 ou T6 qui assurent  The negative clearance once the pressure is released and the notches (3) ensure an extremely solid fixing of the two profiles thanks to the binding between the two surfaces. It is the precision of the shape obtained when spinning aluminum alloy profiles and the high mechanical resistance obtained by treatment in the T5 or T6 state which ensure

la solidité de la liaison par grippage.  the strength of the binding by seizing.

La pression nécessaire à l'assemblage doit être ajustée, une pression trop faible conduisant à un montage incorrect avec des défauts d'accostage et d'alignement, une pression trop forte risquant de détériorer les crans (3) et donc d'affaiblir le grippage et de créer du jeu. Cette pression peut être mise en oeuvre par des machines existant fréquemment dans les ateliers de construction métallique, comme une presse plieuse ou une profileuse à galets, ce qui évite le plus souvent des investissements additionnels.. La presse plieuse comporte une table de montage, des vérins pneumatiques ou hydrauliques et une barre transmettant l'effort, qui peut aller jusqu'à 1 tonne par mètre linéaire. Dans le cas o on utilise une profiteuse à galets, l'assemblage est réalisé à l'avancée, soit avec un seul train de galets, mais en passant  The pressure required for assembly must be adjusted, a pressure that is too low leading to an incorrect assembly with docking and alignment faults, too high a pressure which could damage the notches (3) and therefore weaken the seizure and create play. This pressure can be implemented by machines which frequently exist in metal construction workshops, such as a press brake or a roll forming machine, which most often avoids additional investments. The press brake comprises an assembly table, pneumatic or hydraulic cylinders and a bar transmitting the force, which can go up to 1 ton per linear meter. In the case where a roller profeuse is used, the assembly is carried out in advance, either with a single train of rollers, but passing

deux fois, soit avec deux trains de galets.  twice, either with two sets of pebbles.

L'assemblage selon l'invention permet de rendre solidaires deux ou plusieurs profilés entre eux sans perte de caractéristiques mécaniques dans la zone de liaison, et de constituer ainsi une structure porteuse homogène à la tenue aux efforts auxquels  The assembly according to the invention makes it possible to make two or more sections integral with one another without loss of mechanical characteristics in the connection zone, and thus to constitute a load-bearing structure homogeneous to the resistance to the forces to which

elle est soumise.she is submissive.

Dans le cas de planchers du type de celui représenté à la figure 1, un seul assemblage entre deux profilés suffit à assurer la résistance mécanique nécessaire. On peut ainsi réaliser un hayon élévateur pour camion de longueur 1700 mm et de largeur 2400  In the case of floors of the type shown in FIG. 1, a single assembly between two sections is sufficient to provide the necessary mechanical strength. It is thus possible to produce a tail lift for a truck with a length of 1700 mm and a width of 2400.
