Abstract

The system has a thermoplastic elastomer material continuous joint (30) arranged in an inter-edge space (10). A fixation unit (49) fixes an edge (52) of the continuous joint on a grill (1). A cut (50) is formed in another edge (46) of the continuous joint. An assembling unit (60) is co-operated with the continuous joint, so that the locking finger is entirely placed in the inter-edge space in a position. Two ends (21, 22) of the locking finger are overlapped on two sides of the inter-edge space and are partially penetrated in longitudinal grooves (12, 14) in another position.

Description

La présente invention concerne les systèmes d'assemblage de trois corps entre eux pour former une pièce sensiblement en forme de "T" qui trouvent des applications particulièrement avantageuses dans le domaine des façades dites "murs-rideaux".The present invention relates to the assembling systems of three bodies together to form a substantially "T" -shaped part which find particularly advantageous applications in the field of facades known as "curtain walls".

Un mur-rideau (aussi appelé « façade rideau ») est un type de façade légère. C'est un mur de façade qui assure la fermeture de l'enveloppe d'un bâtiment sans participer à sa stabilité, les charges étant transférées à la fondation principale par des raccordements aux planchers ou aux colonnes du bâtiment. Les panneaux constituant ce mur, qui sont la plupart du temps des doubles vitrages teintés, sont appuyés, étage par étage, sur un squelette fixe ou ossature appelé « grille ». L'ossature des murs-rideaux est principalement constituée essentiellement de cadres d'aluminium extrudé.A curtain wall (also called "curtain wall") is a type of light facade. It is a façade wall that closes the envelope of a building without contributing to its stability, the loads being transferred to the main foundation by connections to the floors or columns of the building. The panels constituting this wall, which are mostly tinted double glazing, are supported, floor by floor, on a fixed skeleton or frame called "grid". The framework of the curtain walls consists mainly of extruded aluminum frames.

Bien que non porteur, un tel mur-rideau doit être conçu pour résister notamment à l'infiltration de fluides comme l'air et l'eau, ces fluides pouvant s'infiltrer accidentellement à travers le mur-rideau par les garnitures des meneaux et des traverses, et par d'éventuels défauts de calfeutrage, et permettre le drainage et l'évacuation en façade des fluides infiltrés.Although non-load bearing, such a curtain wall must be designed to withstand in particular the infiltration of fluids such as air and water, these fluids being able to infiltrate accidentally through the curtain wall by the fittings of the mullions and ties, and possible caulking defects, and allow drainage and evacuation front infiltrated fluids.

Afin d'atteindre ces buts, notamment une bonne fixation des panneaux et une bonne imperméabilité, les murs-rideaux sont munis de moyens de fixation spécialement conçus pour cette technique en coopération avec des garnitures d'étanchéité. Concernant ces dernières, il en existe de plusieurs sortes, sèches : garnitures en néoprène, EPDM, santoprène, silicone, PVC ou polychlorure de vinyle, hypalon, etc., en rubans performés ou analogues, en pâte : silicone, polyuréthane, polysulfide, acrylique, latex, etc.In order to achieve these goals, in particular a good fixing of the panels and a good impermeability, the curtain walls are provided with fastening means specially designed for this technique in cooperation with gaskets. Concerning the latter, there are several types, dry: neoprene, EPDM, santoprene, silicone, PVC or polyvinyl chloride, hypalon, etc., in performance ribbons or similar, in paste: silicone, polyurethane, polysulfide, acrylic , latex, etc.

Des moyens de fixation et d'étanchéité pour ces murs-rideaux sont déjà connus, dont certains décrits dans les brevets EP 1 972 748 , EP 1 581 715 et EP 1 335 079 .Fastening and sealing means for these curtain walls are already known, some of which are described in US Pat. EP 1 972 748 , EP 1 581 715 and EP 1 335 079 .

La présente invention concerne, en référence à l'ensemble des figures, un système d'assemblage de trois corps entre eux pour former une pièce sensiblement en forme de "T".The present invention relates, with reference to all the figures, a system of assembly of three bodies together to form a substantially "T" -shaped part.

Pour la facilité de la présente description et de sa compréhension, ces trois corps sont respectivement dénommés ici "grille 1" pour le corps qui forme la barre verticale du T, et "premier et second panneaux 2, 3" pour les deux corps qui forment respectivement les deux bras latéraux opposés du T de part et d'autre de sa barre verticale.For ease of the present description and its understanding, these three bodies are respectively referred to here as "grid 1" for the body that forms the vertical bar of the T, and "first and second panels 2, 3" for the two bodies that form respectively the two opposite side arms of the T on either side of its vertical bar.

Ceci étant précisé, les deux panneaux 2, 3 sont disposés pour former avec, la grille 1, la pièce en T, de façon qu'ils soient à une distance non nulle l'un de l'autre en définissant un espace inter-bords 10. Les deux panneaux 2, 3 comportent en outre chacun une rainure longitudinale 12, 14, les deux rainures longitudinales étant réalisées respectivement sur les deux bords 16, 17 qui sont en regard quand les deux panneaux sont en position dans l'assemblage final.That being said, the two panels 2, 3 are arranged to form with the grid 1, the T-piece, so that they are at a non-zero distance from one another by defining an inter-edge space 10. The two panels 2, 3 each further comprise a longitudinal groove 12, 14, the two longitudinal grooves being formed respectively on the two edges 16, 17 which are opposite when the two panels are in position in the final assembly.

Il est aussi prévu un doigt de verrouillage oblong 20 dont les deux extrémités 21, 22 sont aptes à coopérer avec respectivement les deux rainures longitudinales 12, 14, ce doigt de verrouillage 20 étant réalisé de façon qu'il ait une largeur inférieure à la largeur de l'espace inter-bords 10, une longueur supérieure à cette largeur de l'espace inter-bords et une épaisseur au plus égale à la plus petite des largeurs respectivement des deux rainures longitudinales 12, 14.There is also provided an oblong locking finger 20 whose two ends 21, 22 are adapted to cooperate with respectively the two longitudinal grooves 12, 14, the locking finger 20 being made so that it has a width less than the width the inter-edge space 10, a length greater than this width of the inter-edge space and a thickness at most equal to the smallest of the widths respectively of the two longitudinal grooves 12, 14.

Selon une caractéristique essentielle de l'invention, le système d'assemblage comporte un joint continu 30 en un matériau élastique définissant un premier axe longitudinal 300 et étant positionné dans l'espace inter-bords 10, et des moyens 49 pour fixer ce joint continu 30 sur la grille 1, par un premier 52 de ses bords.According to an essential characteristic of the invention, the assembly system comprises a continuous seal 30 made of an elastic material defining a first longitudinal axis 300 and being positioned in the inter-border space 10, and means 49 for fixing this continuous seal 30 on the grid 1, by a first 52 of its edges.

Il est en outre réalisé au moins une découpe 50 dans ce joint continu 30 sur son second bord 46 opposé au premier 52, la profondeur de cette découpe 50 jusqu'à son fond 51, c'est-à-dire jusqu'au niveau du point le plus profond de la découpe, définie selon un deuxième axe 4 parallèle à l'axe de la barre du T, étant inférieure à la largeur du joint continu 30, la largeur de la découpe définie selon le premier axe 300 étant au moins égale à la longueur hors tout du doigt de verrouillage 20.At least one cutout 50 is made in this continuous joint 30 on its second edge 46 opposite to the first 52, the depth of this cutout 50 to its bottom 51, that is to say up to the level of the deepest point of the cut, defined along a second axis 4 parallel to the axis of the T bar, being less than the width of the continuous joint 30, the width of the cutout defined along the first axis 300 being at least equal to to the overall length of the locking finger 20.

Le système d'assemblage comporte en outre, puisque les dimensions du doigt de verrouillage 20 le permettent, des moyens 60 pour le monter dans la découpe 50 et en coopération avec le joint continu 30 dans le fond 51 de la découpe 50, de façon qu'il soit apte à prendre au moins deux positions, une première position dans laquelle il est au moins partiellement contenu dans la découpe 50 et entièrement contenu dans l'espace inter-bords 10, et une seconde position, transversale au plan de la découpe, dans laquelle ses deux extrémités 21, 22 débordent de part et d'autre de l'espace inter-bords 10 et pénètrent respectivement au moins partiellement dans les deux rainures 12, 14.The assembly system further comprises, since the dimensions of the locking pin 20 allow it, means 60 for mounting it in the cutout 50 and in cooperation with the continuous seal 30 in the bottom 51 of the cutout 50, so that it is able to take at least two positions, a first position in which it is at least partially contained in the cutout 50 and entirely contained in the inter-border space 10, and a second position, transverse to the plane of the cutout, in which its two ends 21, 22 protrude on either side of the inter-edge space 10 and penetrate respectively at least partially in the two grooves 12, 14.

Il est mentionné ci-dessus que le système d'assemblage comporte au moins une découpe. Cependant, dans la pratique, comme les panneaux ont des longueurs et largeurs importantes, le système d'assemblage comportera une pluralité de ces couples "découpe-doigt de verrouillage" (50-20) régulièrement répartis à une distance déterminée les uns des autres. Cette distance sera définie par les hommes du métier en fonction de la solidité souhaitée pour l'assemblage final.It is mentioned above that the assembly system comprises at least one cut. However, in practice, as the panels have long lengths and widths, the assembly system will include a plurality of these couples "cutting-locking finger" (50-20) regularly distributed at a determined distance from each other. This distance will be defined by those skilled in the art depending on the desired strength for the final assembly.

Par exemple, sur la figure 1, il est représenté deux de ces couples. Dans le couple représenté en partie supérieure de la figure, le doigt de verrouillage est illustré dans sa première position. Dans celui qui est représenté en partie inférieure de la figure, le doigt de verrouillage est illustré dans sa seconde position, celle qui permet de verrouiller les deux panneaux 2, 3 sur la grille 1 comme il sera explicité ci-après.For example, on the figure 1 he is represented two of these couples. In the torque shown in the upper part of the figure, the locking finger is illustrated in its first position. In that which is shown in the lower part of the figure, the locking finger is shown in its second position, which allows to lock the two panels 2, 3 on the grid 1 as will be explained below.

De même, le joint continu 30 peut être constitué par une pluralité de portions de joint qui sont aboutées les unes aux autres, avantageusement de façon étanche, par exemple par collage, soudage, etc., selon la matière constitutive de ces portions de joint.Similarly, the continuous seal 30 may be constituted by a plurality of joint portions which abut one another, preferably sealingly, for example by gluing, welding, etc., depending on the constituent material of these joint portions.

Selon une réalisation préférentielle, les moyens 60 pour monter le doigt de verrouillage 20 dans la découpe 50 comportent, comme plus particulièrement visible sur les figures 2, 6 et 7, une embase cylindrique 61 au moins partiellement de révolution solidaire de l'un des deux éléments suivants : doigt de verrouillage 20 et joint continu 30 ; et une partie en creux 62 réalisée sur l'autre de ces deux éléments, cette partie en creux étant sensiblement complémentaire de l'embase pour que l'embase cylindrique 61 puisse être montée rotative dans cette partie en creux autour d'un axe de rotation 63, l'embase cylindrique et la partie en creux étant en outre réalisées de façon que cet axe de rotation 63 soit sensiblement parallèle au deuxième axe 4 défini précédemment.According to a preferred embodiment, the means 60 for mounting the locking finger 20 in the blank 50 comprise, as more particularly visible on the figures 2 , 6 and 7 , a cylindrical base 61 at least partially of revolution integral with one of the following two elements: locking finger 20 and continuous seal 30; and a recessed portion 62 formed on the other of these two elements, this recessed portion being substantially complementary to the base so that the cylindrical base 61 can be rotatably mounted in this recessed portion about an axis of rotation 63, the cylindrical base and the recessed portion being further provided such that this axis of rotation 63 is substantially parallel to the second axis 4 defined above.

De façon préférentielle, comme dans le mode de réalisation illustré sur les figures, l'embase 61 est solidaire du doigt de verrouillage 20 et la partie en creux 62 est donc réalisée dans le joint continu 30, plus spécifiquement dans le fond de la découpe 50.Preferably, as in the embodiment illustrated in the figures, the base 61 is integral with the locking finger 20 and the recessed portion 62 is formed in the continuous seal 30, more specifically in the bottom of the blank 50 .

De façon avantageuse, le système comporte en outre des moyens pour indexer la rotation du doigt de verrouillage 20 par rapport au joint continu 30 pour définir de façon certaine ses deux première et seconde positions telles que définies auparavant.Advantageously, the system further comprises means for indexing the rotation of the locking pin 20 relative to the continuous seal 30 to definitively define its two first and second positions as defined before.

Quand, comme illustré sur les figures, l'embase cylindrique 61 est solidaire du doigt de verrouillage 20, les moyens pour indexer la rotation du doigt de verrouillage par rapport au joint continu 30 sont constitués, figures 6 et 7, par au moins un ergot 65a, 65b, dans l'exemple représenté deux ergots 65a et 65b solidaires, en saillie de l'embase cylindrique 61 de façon à être apte à buter contre deux rebords déterminés de la partie en creux 62 lors de la rotation de l'embase cylindrique dans la partie en creux. Ces deux rebords seront déterminés par l'homme du métier en fonction de l'amplitude de rotation souhaitée du doigt de verrouillage 20 par rapport au joint continu 30, sachant que cette amplitude est généralement d'une valeur sensiblement égale à quatre-vingt-dix degrés.When, as illustrated in the figures, the cylindrical base 61 is integral with the locking pin 20, the means for indexing the rotation of the locking finger with respect to the continuous seal 30 are constituted, Figures 6 and 7 by at least one lug 65a, 65b, in the example shown two lugs 65a and 65b integral, projecting from the cylindrical base 61 so as to be able to abut against two determined edges of the recessed portion 62 during the rotation of the cylindrical base in the recessed portion. These two flanges will be determined by the skilled person according to the desired rotation amplitude of the locking pin 20 relative to the continuous seal 30, knowing that this amplitude is generally of a value substantially equal to ninety degrees.

Comme plus particulièrement illustré sur les figures 3, 4 et 5 qui représentent une réalisation industrielle du joint continu 30, ce dernier comporte une âme centrale 31 qui est donc, elle aussi, continue et au moins deux premières pattes latérales 32, 33, elles aussi continues, respectivement solidaires, par une première 34, 35 de leurs extrémités, des deux parois longitudinales 36, 37 de l'âme centrale 31 en faisant, avec ces parois longitudinales 36, 37, un angle non nul compris entre zéro et quatre-vingt-dix degrés, limites non comprises, quand ces pattes ne sont pas soumises à une force de déformation, comme c'est le cas par exemple sur ces figures.As more particularly illustrated on Figures 3, 4 and 5 which represent an industrial embodiment of the continuous joint 30, the latter comprises a central core 31 which is also also continuous and at least two first lateral lugs 32, 33, they also continuous, respectively integral, by a first 34, 35 of their ends, two longitudinal walls 36, 37 of the central core 31 by making, with these longitudinal walls 36, 37, a non-zero angle between zero and ninety degrees, limits not included, when these legs do not are not subjected to a deformation force, as is the case for example in these figures.

Ces deux premières pattes latérales 32, 33 sont agencées sur l'âme centrale 31 de façon que leurs premières extrémités 34, 35 soient situées sur la partie 53 de cette âme centrale qui est définie entre le fond 51 de la découpe 50 (le point le plus profond de cette découpe) et le premier bord 52 du joint continu 30 qui est en regard de la grille 1. De cette façon, quand la découpe est réalisée dans le joint continu 30, ces deux premières pattes latérales 32, 33 ne sont pas interrompues par cette découpe 50, ce qui présente un autre avantage de la présente invention qui sera explicité ci-après.These first two lateral tabs 32, 33 are arranged on the central core 31 so that their first ends 34, 35 are situated on the part 53 of this central core which is defined between the bottom 51 of the cutout 50 (the point deeper of this cut) and the first edge 52 of the continuous seal 30 which is opposite the gate 1. In this way, when the cut is made in the continuous seal 30, these two first lateral lugs 32, 33 are not interrupted by this cut 50, which has another advantage of the present invention which will be explained below.

Ces premières pattes latérales 32, 33 doivent assurer généralement une fonction d'étanchéité, d'isolation thermique et phonique. À cet effet, la distance hors tout définie entre les deux points les plus éloignés de ces deux premières pattes latérales, quand elles ne sont pas soumises à une force de déformation, sera légèrement inférieure, ou égale, ou sensiblement égale, à la largeur de l'espace inter-bords 10. De cette façon, quand les deux panneaux 2, 3 sont mis en position par rapport au joint continu 30, ils s'approchent des deux premières pattes latérales 32, 33 par leurs deux bords 16, 17, par une distance respective généralement sensiblement égale ou inférieure à 2 mm, et, de ce fait, créent un cloisonnement de l'espace inter-bords.These first lateral lugs 32, 33 must generally provide a sealing function, thermal and sound insulation. For this purpose, the overall distance defined between the two points farthest from these first two lateral lugs, when they are not subjected to a deformation force, will be slightly less than, equal to, or substantially equal to the width of In this way, when the two panels 2, 3 are placed in position relative to the continuous seal 30, they approach the two first lateral tabs 32, 33 by their two edges 16, 17, by a respective distance generally substantially equal to or less than 2 mm, and, as a result, create a partitioning of the inter-edge space.

De façon encore plus avantageuse, pour obtenir une meilleure étanchéité fluidique dans certaines applications, comme explicité ci-après, ces premières pattes latérales sont agencées par rapport à l'âme centrale 31 de façon que leurs points les plus éloignés, qui sont de préférence leurs extrémités libres, soient sensiblement situés dans un plan perpendiculaire au deuxième axe 4 et dans l'espace Esp1, figure 5, défini entre le plan passant par les deux premières extrémités 34, 35 des premières pattes latérales et un plan passant par le doigt de verrouillage 20 et sensiblement perpendiculaire au deuxième axe 4.Even more advantageously, to obtain a better seal in certain applications, as explained below, these first lateral lugs are arranged relative to the central core 31 so that their farthest points, which are preferably their free ends, are substantially located in a plane perpendicular to the second axis 4 and in space Esp1, figure 5 , defined between the plane passing through the first two ends 34, 35 of the first lateral lugs and a plane passing through the locking pin 20 and substantially perpendicular to the second axis 4.

Toujours dans le but d'améliorer encore l'étanchéité aussi bien fluidique que thermique et/ou phonique, le système d'assemblage comporte en outre avantageusement au moins deux autres joints latéraux 40, 41, eux aussi continus, situés dans un espace défini entre deux plans passant respectivement par le doigt de verrouillage 20 et le second bord 46 du joint continu 30. Ces deux joints latéraux 40, 41 sont interposés entre l'âme centrale 31 et respectivement les deux bords en regard 16, 17 des deux panneaux 2, 3.Still with the aim of further improving fluidic, thermal and / or phonic sealing, the assembly system advantageously also comprises at least two other lateral joints 40, 41, which are also continuous, situated in a space defined between two planes passing respectively through the locking finger 20 and the second edge 46 of the continuous seal 30. These two lateral seals 40, 41 are interposed between the central core 31 and respectively the two opposite edges 16, 17 of the two panels 2, 3.

Ces deux joints latéraux 40, 41 sont bien entendu interrompus lors de la réalisation de la découpe 50, sur une longueur qui est égale à celle de la découpe. Mais la présence des deux premières pattes latérales 32, 33, lorsqu'elles font joints comme expliqué plus haut, en étant situées en dessous du doigt de verrouillage 20, permettent de pallier la discontinuité de l'étanchéité du fait de la découpe 50.These two side seals 40, 41 are of course interrupted during the making of the blank 50, over a length which is equal to that of the blank. But the presence of the first two lateral lugs 32, 33, when joined as explained above, being located below the locking pin 20, make it possible to overcome the discontinuity of the seal due to the cut 50.

Selon une réalisation préférentielle, comme illustré, ces deux joints latéraux 40, 41 sont respectivement constitués par deux secondes pattes latérales 42, 43 solidaires, par une première 44, 45 de leurs extrémités qui sont situées dans l'espace compris entre les deux plans passant respectivement par le second bord 46 du joint continu 30 et le doigt de verrouillage 20, et sont respectivement solidaires des deux parois longitudinales 36, 37 de l'âme centrale 31 en faisant avec ces parois longitudinales 36, 37 un angle non nul compris entre zéro et quatre-vingt-dix degrés, limites non comprises, la distance hors tout définie entre les deux points les plus éloignés de ces deux secondes pattes latérales 42, 43 quand elles ne sont pas soumises à une force de déformation, étant de préférence sera légèrement inférieure à la largeur de l'espace inter-bords 10.According to a preferred embodiment, as illustrated, these two lateral seals 40, 41 are constituted respectively by two second lateral lugs 42, 43 integral, by a first 44, 45 of their ends which are located in the space between the two passing planes. respectively by the second edge 46 of the continuous seal 30 and the locking pin 20, and are respectively integral with the two longitudinal walls 36, 37 of the central core 31 by making with these longitudinal walls 36, 37 a non-zero angle between zero and ninety degrees, not including limits, the overall distance defined between the two points furthest from these two second lateral tabs 42, 43 when they are not subjected to a deformation force, preferably being slightly less than the width of the inter-border space 10.

De plus, ces secondes pattes latérales 42, 43 sont agencées par rapport à l'âme centrale 31 de façon que leurs points les plus éloignés soient sensiblement situés dans un plan perpendiculaire au deuxième axe 4 et dans l'espace Esp2, figure 5, défini entre le plan passant par les deux premières extrémités 44, 45 des secondes pattes latérales et un plan passant par le doigt de verrouillage 20 et sensiblement perpendiculaire au deuxième axe 4.In addition, these second lateral tabs 42, 43 are arranged relative to the central core 31 so that their most distant points are substantially located in a plane perpendicular to the second axis 4 and in the space Esp2, figure 5 , defined between the plane passing through the first two ends 44, 45 of the second lateral lugs and a plane passing through the locking finger 20 and substantially perpendicular to the second axis 4.

En outre, dans un but de sécurité, notamment quand les deux panneaux 2, 3 sont mis en place, pour éviter que les deux premières pattes latérales 32, 33 ne se retournent, elles sont réalisées de façon qu'elles soient assez rigides, et en tout cas plus rigides que les secondes pattes latérales 42, 43. Pour ce faire, comme l'âme centrale 31 et les quatre pattes 32, 33, 42, 43 sont réalisées en une seule pièce notamment par filage ou moulage, les premières pattes latérales 32, 33 sont réalisées de façon à être plus épaisses que les secondes pattes latérales 42, 43.In addition, for safety purposes, especially when the two panels 2, 3 are put in place, to prevent the first two lateral lugs 32, 33 from turning, they are made so that they are quite rigid, and in any case more rigid than the second lateral lugs 42, 43. To do this, as the central core 31 and the four lugs 32, 33, 42, 43 are made in one piece, in particular by spinning or molding, the first legs 32, 33 are made to be thicker than the second lateral tabs 42, 43.

Pour la sécurité de la fixation de l'assemblage, il est préférable que le système d'assemblage comporte en outre des moyens 70 pour solidariser le doigt de verrouillage 20 avec la grille 1, surtout quand il se trouve dans sa seconde position. Ces derniers moyens 70 peuvent être réalisés de diverses façons, par exemple, comme illustré sur la figure 2, par une vis de préférence auto-taraudante qui peut passer dans une percée réalisée dans le doigt de verrouillage et, après avoir percé la partie 53 de l'âme centrale 31 qui se trouve sous le doigt de verrouillage 20, se visser dans la grille 1 qui est généralement métallique.For the security of fastening the assembly, it is preferable that the assembly system further comprises means 70 for securing the locking finger 20 with the grid 1, especially when it is in its second position. The latter means 70 can be made in various ways, for example, as illustrated in FIG. figure 2 by a preferably self-tapping screw which can pass into a breakthrough made in the locking finger and, after having pierced the portion 53 of the central core 31 which is under the locking pin 20, screw into the grid 1 which is usually metallic.

Toujours pour plus de sécurité et pour améliorer les diverses étanchéités définies ci-avant, ainsi que réaliser une protection du doigt de verrouillage qui peut être métallique ou réalisé en matière plastique, il est avantageux que le système d'assemblage comporte en outre, comme illustré schématiquement en traits-points sur la figure 1, des bouchons 80 aptes à être respectivement enfichés dans les découpes 50 pour, d'une part recouvrir le doigt de verrouillage 20 dans chaque découpe, et d'autre part obturer cette découpe 50. Il est aussi avantageux que ces bouchons 80 comportent la partie de l'âme centrale 31 et les parties des deux joints latéraux 40, 41 qui ont été éliminées lors de la réalisation de la découpe 50, comme cela a été explicité auparavant, dans le but de parfaire les étanchéités.Still for greater security and to improve the various seals defined above, as well as to provide a protection of the locking pin which may be metallic or made of plastic, it is advantageous that the assembly system furthermore comprises, as illustrated schematically in dot-dashes on the figure 1 plugs 80 adapted to be respectively plugged into the cutouts 50 to firstly cover the locking finger 20 in each cut, and secondly to close off this cutout 50. It is also advantageous that these plugs 80 comprise the part the central core 31 and the parts of the two side seals 40, 41 which were eliminated during the production of the blank 50, as has been explained before, in order to perfect the seals.

De façon préférentielle, les bouchons 80 et le joint continu 30 sont réalisés dans des matériaux différents, par exemple dans un matériau de type TPE pour les bouchons, le joint continu 30 étant réalisé par exemple en EPDM, et présentent une section extérieure identique à celle du joint continu, pour assurer une parfaite continuité du joint 30 sur tout son long quand ils sont enfichés, et notamment la continuité des deux joints latéraux 40, 41.Preferably, the plugs 80 and the continuous seal 30 are made of different materials, for example in a TPE-type material for the plugs, the continuous seal 30 being made for example of EPDM, and having a outer section identical to that of the continuous seal, to ensure a perfect continuity of the seal 30 over its entire length when they are plugged, and in particular the continuity of the two side seals 40, 41.

Comme mentionné auparavant, le système d'assemblage comporte des moyens 49 pour fixer le joint continu 30 sur la grille 1. De façon avantageuse, comme illustré sur les figures et plus particulièrement visible sur les figures 2, 4 et 5, ces moyens 49 sont constitués par une partie en saillie 47, en forme de lame ou analogue, solidaire de la face de l'âme centrale 31 située en regard de la grille 1 et par une gorge longitudinale 5 réalisée dans la grille 1, cette partie en saillie 47 et la gorge longitudinale 5 étant agencées l'une par rapport à l'autre de façon que la partie en saillie soit apte à s'enficher en force dans la gorge longitudinale pour constituer la fixation entre le joint continu 30 et la grille 1.As mentioned before, the assembly system comprises means 49 for fixing the continuous seal 30 on the grid 1. Advantageously, as illustrated in the figures and more particularly visible on the figures 2 , 4 and 5 these means 49 are constituted by a projecting portion 47, in the shape of a blade or the like, integral with the face of the central core 31 facing the grid 1 and with a longitudinal groove 5 made in the grid 1, this protruding portion 47 and the longitudinal groove 5 being arranged relative to each other so that the projecting portion is adapted to be plugged into force in the longitudinal groove to form the fixing between the continuous seal 30 and the grid 1.

De façon à assurer une bonne portance des panneaux 2, 3 sur la grille 1, le système d'assemblage comporte en outre, de façon très préférentielle, comme montré figure 2, des joints d'appui 91, 92 montés au contact entre la grille 1 et respectivement les deux panneaux 2, 3, ces joints d'appui étant positionnés de part et d'autre de la partie de la grille 1, autant sur les montants que sur les traverses de celle-ci, dans laquelle est réalisée la gorge 5, par exemple respectivement sur deux épaulements comme ceux illustrés sur cette figure 2.In order to ensure good lift of the panels 2, 3 on the grid 1, the assembly system also comprises, very preferably, as shown figure 2 , bearing seals 91, 92 mounted in contact between the grid 1 and respectively the two panels 2, 3, these bearing seals being positioned on either side of the part of the grid 1, both on the uprights than on the crosspieces thereof, in which the groove 5 is made, for example respectively on two shoulders like those illustrated in this figure 2 .

Il est en outre généralement prévu, pour améliorer lesdites étanchéités et pour une question d'aspect extérieur de la façade de type mur-rideau, de manière connue, un moyen de joint d'étanchéité 100, continu sur le côté entre les deux bords en vis-à-vis de deux panneaux 2, 3 juxtaposés, comme illustré schématiquement et partiellement sur la figure 2, remplissant l'espace inter-bords 10 en étant en contact sur les deux parties de tranches des panneaux 2, 3 situées à l'opposé de celles qui sont du côté de la grille 1, et des moyens pour fixer ce moyen de joint d'étanchéité 100 sur le joint continu 30, par exemple par clippage ou analogue dans la cannelure réalisée sur le bord 46 du joint continu 30.It is furthermore generally provided, for improving said seals and for a question of external appearance of the curtain wall type facade, in a known manner, a seal means 100, continuous on the side between the two edges. vis-à-vis two panels 2, 3 juxtaposed, as shown schematically and partially on the figure 2 filling the inter-border space 10 by being in contact on the two slice portions of the panels 2, 3 situated opposite to those which are on the side of the grid 1, and means for fixing this sealing means sealing 100 on the continuous joint 30, for example by clipping or the like in the groove formed on the edge 46 of the continuous joint 30.

Ce moyen de joint d'étanchéité 100 peut par exemple adopter la forme d'un profilé 101 support de joint en matière plastique, continu par exemple le long d'un montant de la grille et discontinu sur les traverses de ladite grille au passage des montants, généralement clippé dans la cannelure réalisée sur le bord 46 du joint continu 30, comme représenté sur la figure 2, l'espace restant compris entre la partie restante des tranches des panneaux 2, 3 en vis-à-vis, et ce support de joint 101 étant comblé par un mastic étanche (non représenté) qui affleure sensiblement en façade avec les faces des panneaux 2, 3 opposées à celle en contact avec les joints 91, 92 du côté de la grille, et qui est déposé par un opérateur.This sealing means 100 may, for example, take the form of a plastic support support profile 101, continuous for example along a grid upright and discontinuous on the crosspieces of said grid at the passage of the uprights. , usually clipped into the groove made on the edge 46 of the seal continuous 30, as shown on the figure 2 , the remaining space between the remaining portion of the slices of the panels 2, 3 facing each other, and this joint support 101 being filled by a waterproof sealant (not shown) which is flush substantially in front with the faces of the panels 2, 3 opposed to that in contact with the joints 91, 92 on the side of the grid, and which is deposited by an operator.

De manière alternative à la solution ci-dessus, également connue, le profilé support de joint 101 et le mastic étanche peuvent par exemple être remplacés par un joint caoutchouc à lèvres (non représenté) qui vient se fixer, généralement par clippage, dans la cannelure réalisée sur le bord 46 du joint continu 30.As an alternative to the above solution, also known, the joint support profile 101 and the sealant seal may for example be replaced by a rubber lip seal (not shown) which is fixed, generally by clipping, in the groove performed on the edge 46 of the continuous joint 30.

Le système d'assemblage selon l'invention trouve des applications dans de nombreux domaines, particulièrement avantageusement dans le domaine des murs-rideaux ou façades-rideaux, comme mentionné au préambule de la présente description.The assembly system according to the invention has applications in many fields, particularly advantageously in the field of curtain walls or curtain walls, as mentioned in the preamble of the present description.

Dans l'exemple représenté, la grille 1 est un élément d'une armature de façade d'immeuble et les deux panneaux sont des doubles-vitrages, les rainures longitudinales 12, 14 définies de façon générique ci-avant étant alors constituées par une partie de l'espace compris entre les deux vitres qui forment ces doubles-vitrages.In the example shown, the grid 1 is an element of a building facade reinforcement and the two panels are double-glazed, the longitudinal grooves 12, 14 defined generically above being then constituted by a part the space between the two panes that form these double glazing.

Le système d'assemblage s'utilise de la façon suivante, sachant que la description de cette utilisation sera faite dans le cas de la réalisation d'une façade d'immeuble de type mur-rideau ou analogue.The assembly system is used in the following manner, knowing that the description of this use will be made in the case of the realization of a curtain wall-like building facade or the like.

Sur la façade de la structure porteuse en béton, acier, ou analogue, est d'abord fixée une armature (ou ossature) désignée ici par le terme générique grille 1 dotée de ses accessoires. Cette grille ainsi équipée est avantageusement préparée en atelier, où ses accessoires sont réalisés puis montés sur la grille, puis cette dernière est amenée sur chantier et fixée sur la structure porteuse.On the front of the supporting structure of concrete, steel, or the like, is first fixed a frame (or frame) here designated by the generic term grid 1 with its accessories. This grid and equipped is advantageously prepared in the workshop, where its accessories are made and mounted on the grid, then the latter is brought to the site and fixed on the supporting structure.

Les découpes 50 du joint continu 30 sont ainsi avantageusement réalisées en atelier, et ce joint est avantageusement fixé sur la grille également en atelier par enfichage de sa partie en saillie 47 dans la gorge 5, cet enfichage étant suffisant pour maintenir le joint continu 30 sur toute sa longueur solidaire de la grille 1. Il en est de même pour les joints d'appui 91 et 92.The cuts 50 of the continuous seal 30 are thus advantageously made in the workshop, and this seal is advantageously fixed on the grid also in the workshop by plugging its projecting portion 47 into the groove 5, this insertion being sufficient to maintain the continuous seal 30 on its entire length integral with the grid 1. It is the same for the support joints 91 and 92.

Ensuite, toujours en atelier, les doigts de verrouillage 20 sont avantageusement pré-montés dans le fond 51 des découpes 50 dans leur première position, partie supérieure de la figure 1 et figure 6, par exemple par un vissage partiel de la vis 70 au moins dans le joint continu 30.Then, still in the workshop, the locking fingers 20 are advantageously pre-mounted in the bottom 51 of the blanks 50 in their first position, upper part of the figure 1 and figure 6 , for example by a partial screwing of the screw 70 at least in the continuous joint 30.

Il est à noter que les montages du joint continu 30 sur la grille, des doigts de verrouillage 20 dans les découpes 50 et notamment des joints d'appui 91, 92 sur la grille 1 peuvent de manière alternative se faire sur site, sachant que la continuité du joint 30 rend cette opération plus aisée lorsqu'elle est réalisée sur chantier que selon les systèmes d'assemblage de l'art antérieur pour lesquels l'opérateur doit manipuler une grande quantité de segments de joint en vue de les disposer et de les fixer entre les doigts de verrouillage en évitant de les faire tomber ou d'en oublier.It should be noted that the assemblies of the continuous seal 30 on the grid, locking fingers 20 in the cutouts 50 and in particular support joints 91, 92 on the grid 1 can alternatively be done on site, knowing that the continuity of the joint 30 makes this operation easier when it is performed on site than according to the assembly systems of the prior art for which the operator must handle a large amount of joint segments for disposal and the secure between the locking fingers, making sure they are not dropped or forgotten.

Une fois la grille en place sur la façade avec ses accessoires comme expliqué ci-dessus, les panneaux double-vitrage 2, 3 avec leurs rainures 12, 14 sont alors positionnés un par un en les faisant reposer sur les joints d'appui 91, 92, le joint continu 30, et les cales d'appui (non représenté) le cas échéant, de manière conventionnelle. Puis, les doigts de verrouillage 20 sont pivotés, par tous moyens, pour les faire passer de leur première position à leur seconde position définie par le ou les ergots 65a, 65b qui viennent en butée (partie inférieure de la figure 1 et figures 2 et 5), c'est-à-dire celle dans laquelle leurs extrémités 21, 22 pénètrent dans les rainures longitudinales 12, 14 et viennent en appui sur la paroi latérale de celles-ci pour appliquer les doubles-vitrages avec une certaine force sur les deux joints d'appui 91, 92.Once the grid in place on the front with its accessories as explained above, the double-glazed panels 2, 3 with their grooves 12, 14 are then positioned one by one by resting them on the support joints 91, 92, the continuous seal 30, and the bearing blocks (not shown) where appropriate, in a conventional manner. Then, the locking fingers 20 are pivoted, by any means, to move them from their first position to their second position defined by the or lugs 65a, 65b which come into abutment (lower part of the Figure 1 and Figures 2 and 5 ), that is to say the one in which their ends 21, 22 penetrate into the longitudinal grooves 12, 14 and bear against the side wall thereof to apply the double glazing with a certain force on both support joints 91, 92.

Ensuite, s'ils sont prévus, les bouchons 80 et les couvre-joints 100 sont positionnés comme décrit ci-avant.Then, if they are provided, the plugs 80 and the joint covers 100 are positioned as described above.

À la description faite ci-dessus, il apparaît nettement que le système d'assemblage selon l'invention présente de nombreux avantages par rapport aux systèmes similaires de l'art antérieur, par exemple une plus grande facilité de son montage et l'obtention d'une très bonne étanchéité aussi bien fluidique que thermique et/ou phonique. Il permet en particulier d'éviter la réalisation d'une grande partie des opérations d'assemblage sur site, en permettant leur transfert en atelier où des machines peuvent par exemple assurer plus de régularité dans l'espacement entre les doigts de verrouillage, dont la détermination représente un paramètre important de sécurité qui n'est ainsi plus soumis aux seuls opérateurs lesquels ne travaillent pas toujours dans les meilleures conditions possibles de positions compte tenu de la localisation des pièces assemblées.As described above, it clearly appears that the assembly system according to the invention has many advantages over similar systems of the prior art, for example a greater ease of assembly and obtaining a very good sealing as well fluidic as thermal and / or phonic. In particular, it makes it possible to avoid carrying out a large part of the on-site assembly operations, by allowing them to be transferred to the workshop where machines can, for example, ensure more regularity in the spacing between the locking fingers, the This determination represents an important safety parameter which is thus no longer subject to the operators who do not always work in the best possible conditions. positions taking into account the location of the assembled parts.

Il faut en outre souligner que, du fait de la présence des deux premières pattes latérales 32, 33 sans discontinuité tout le long du joint continu 30, et en outre avantageusement de leur forme et de leur inclinaison, lorsqu'elles se trouvent en partie basse des doubles-vitrages en façade et positionnées de façon horizontale, si, malgré la présence de tous les joints décrits ci-avant, notamment les deux joints latéraux 40, 41, et/ou le bouchon 80 et/ou le joint d'étanchéité 100, de l'eau d'infiltration (pluie, neige, condensation, fonte de glace, etc.) arrivait malgré tout jusqu'à ces premières pattes latérales 32, 33, celles-ci joueraient alors le rôle de rigoles longitudinales de récupération en forme de "V" pour guider l'eau ainsi récupérée vers des endroits appropriés pour l'éliminer vers l'extérieur de la façade, comme généralement les normes en la matière l'exigent. Ces endroits appropriés pour l'évacuation de l'eau de ruissellement dans les feuillures, en façade, sont soit placés aux intersections angulaires des panneaux, soit répartis le long du bord longitudinal inférieur d'un panneau à des endroits sélectionnés où des entailles transversales de guidage des eaux ont été réalisées dans les lèvres des joints 40 et 32 en contact ou en vis-à-vis avec le bord du panneau, en vue de guider ces eaux vers et dans des ouvertures débouchant en façade à travers le moyen de joint d'étanchéité 100.It should also be emphasized that, because of the presence of the first two lateral lugs 32, 33 without discontinuity all along the continuous joint 30, and moreover advantageously of their shape and their inclination, when they are in the lower part double-glazing facades and positioned horizontally, if, despite the presence of all the joints described above, including the two side seals 40, 41, and / or the plug 80 and / or the seal 100 , infiltration water (rain, snow, condensation, melting ice, etc.) still arrived until these first lateral lugs 32, 33, they would then play the role of longitudinal channels of recovery in form "V" to guide the water thus recovered to appropriate places to eliminate it to the outside of the facade, as usually standards require. These locations, suitable for the discharge of runoff water into the rabbets, on the façade, are either placed at the angular intersections of the panels, or distributed along the lower longitudinal edge of a panel at selected locations where transverse cuts of water guidance have been carried out in the lips of the joints 40 and 32 in contact with or in relation to the edge of the panel, in order to guide these waters to and in openings opening on the facade through the sealing means. sealing 100.
