Abstract

The invention relates to a system for sealing between the frames of a framework for a facade of the shutter-wall type, in which the gaps (5) between adjacent glazing elements (panes of glass) (3,4) are open to the surrounding atmosphere and allow the natural elements (bad weather) to penetrate inside the framework. According to the invention, this system comprises, in combination, a primary seal (6) made of elastomeric material, positioned vertically and set back inside the building relative to the facade, and a secondary seal (7), also made of elastomeric material, a first part (7b) of which forms a flap which extends horizontally, between two crossmembers of superimposed frames (2), in the direction of the facade, between the primary seal (6) and the facade, whereas a second part (7a), joined to the first part and rising perpendicularly to the latter, extends to the rear of the primary seal (6), relative to the facade, and is inserted between facing vertical surfaces of the two adjacent frames. <IMAGE>

Description

La présente invention concerne une nouvelle façade de mur-rideau munie d'un système d'étanchéité entre les cadres de l'ossature de façade.The present invention relates to a new curtain wall facade provided with a sealing system between the frames of the facade framework.

On sait que, pour la réalisation de l'ossature de façades entièrement ou partiellement vitrées, on utilise des cadres constitués de profilés mécaniques parallèlement réalisés en usine, qui sont assemblés en usine et non sur les chantiers.It is known that, for the realization of the framework of fully or partially glazed facades, frames consisting of mechanical profiles are used which are produced in parallel in the factory, which are assembled in the factory and not on building sites.

Ces cadres sont juxtaposés longitudinalement ou verticalement, et la perméabilité à l'air et à l'eau des façades ainsi réalisées est naturellement tributaire, entre autres, de l'étanchéité de la jonction entre cadres.These frames are juxtaposed longitudinally or vertically, and the air and water permeability of the facades thus produced is naturally dependent, among other things, on the tightness of the junction between frames.

On utilise, dans ce but, divers systèmes d'étanchéité utilisant notamment :

  • des joints de silicone sur fond de joint entre cadres;
  • des joints extrudés, en EPDM ou en un matériau similaire, qui ont une section transversale en V, les deux branches du V étant collées ou clipées contre deux côtés contigus de deux cadres adjacents.
Various sealing systems are used for this purpose, using in particular:
  • silicone seals on the bottom of the joint between frames;
  • extruded joints, made of EPDM or a similar material, which have a V cross section, the two branches of the V being glued or clipped against two contiguous sides of two adjacent frames.

Ces systèmes d'étanchéité sont généralement disposés au voisinage immédiat de la façade, en avant de la structure des cadres.These sealing systems are generally arranged in the immediate vicinity of the facade, in front of the frame structure.

La présente invention vise à proposer un système d'étanchéité à l'air et à l'eau, qui est décalé vers l'intérieur par rapport à la façade, de manière à laisser pénétrer l'eau verticalement entre les cadres, pour la réévacuer vers l'extérieur suivant un plan longitudinal.The present invention aims to provide an air and water tightness system, which is offset inwardly relative to the facade, so as to allow water to penetrate vertically between the frames, to re-evacuate it. outwards along a longitudinal plane.

Ce décalage vers l'intérieur vise à assurer un meilleur équilibrage des pressions régnant à l'intérieur et à l'extérieur du bâtiment, au niveau du système d'étanchéité.This inward shift aims to ensure better balancing of the pressures prevailing inside and outside the building, at the level of the sealing system.

En décalant le système d'étanchéité vers l'intérieur, il est en outre possible de récupérer d'éventuelles infiltrations d'eau entre cadres et traverses et de les évacuer vers l'extérieur.By shifting the sealing system inwards, it is also possible to recover any water infiltration between frames and crosspieces and to evacuate them to the outside.

On connaît à cet effet par GB-A-2 179 974 une façade de mur-rideau pourvue d'un système d'étanchéité entre les cadres d'ossature de la façade, dans laquelle les espaces (p.4, l.61-75) entre vitrages contigus 20 sont ouverts à l'atmosphère ambiante et laissent pénétrer les intempéries vers l'intérieur de l'ossature 92 (p.4, l.19-24), ce système comprenant en combinaison un joint d'étanchéité primaire 60 en un élastomère, disposé verticalement et décalé vers l'intérieur de l'immeuble par rapport aux vitrages, et un joint d'étanchéité secondaire 110 (p.4, l.12-18), également en un élastomère, dont une première partie 114, 188 formant bavette s'étend à l'horizontale, entre deux traverses de cadres supperposées, à partir du joint d'étanchéité primaire 60 en direction des vitrages, tandis qu'une seconde partie 112, attenante à la première et redressée perpendiculairement à celle-ci, s'étend à l'arrière du joint primaire 60.GB-A-2 179 974 discloses a curtain wall facade provided with a sealing system between the framework frames of the facade, in which the spaces (p.4, l.61- 75) between adjoining glazings 20 are open to the ambient atmosphere and allow the weather to penetrate towards the interior of the frame 92 (p.4, l.19-24), this system comprising in combination a primary seal 60 in an elastomer, arranged vertically and offset towards the interior of the building with respect to the glazing, and a secondary seal 110 (p.4, l.12-18), also in an elastomer, of which a first part 114, 188 forming a flap extends horizontally, between two crosspieces of superposed frames, from the primary seal 60 in the direction of the glazing, while a second part 112, adjoining the first and straightened perpendicularly to it, extends behind the primary seal 60.

L'invention vise à proposer une façade de mur rideau de ce type dans laquelle la seconde portion de joint est interposée étanche et solidaire de deux traverses de cadres contigus, ce qui renforce l'étanchéité et la rigidité d'assemblage de l'ensemble.The invention aims to provide a curtain wall facade of this type in which the second seal portion is interposed sealed and secured to two crossbeams of contiguous frames, which strengthens the seal and the assembly rigidity of the assembly.

A cet effet, l'invention a pour objet une façade de mur-rideau conforme à la revendication 1.To this end, the invention relates to a curtain wall facade according to claim 1.

De façon avantageuse, le joint d'étanchéité primaire sera logé dans des évidements verticaux des cadres et comportera des ailettes faisant saillie à sa surface et pincées et déformées entre le corps du joint et les parois latérales de son ou ses logements.Advantageously, the primary seal will be housed in vertical recesses of the frames and will have fins projecting from its surface and pinched and deformed between the body of the seal and the side walls of its or its housings.

De façon analogue, la seconde partie du joint d'étanchéité secondaire disposée à la verticale à l'arrière du joint d'étanchéité primaire comprendra des ailettes en saillie à sa surface, ces ailettes étant pincées et déformées entre les surfaces en regard des deux traverses de cadres superposées.Similarly, the second part of the secondary seal placed vertically behind the primary seal will include fins projecting from its surface, these fins being pinched and deformed between the facing surfaces of the two crosspieces. overlapping frames.

De façon particulièrement préférée, cette seconde partie du joint d'étanchéité secondaire pourra être repliée sur elle-même pour coiffer une partie d'un cadre faisant saillie verticalement, qui est engagée dans un évidement du cadre immédiatement supérieur.In a particularly preferred manner, this second part of the secondary seal can be folded back on itself to cover part of a frame. protruding vertically, which is engaged in a recess in the immediately upper frame.

Les deux joints pourront être réalisés en un élastomère tel que l'EPDM ou similaire.The two seals can be made of an elastomer such as EPDM or the like.

Les dessins annexés illustrent une forme de mise en oeuvre de l'invention. Ils n'ont aucun caractère limitatif et si, en particulier, la structure représentée comprend un remplissage du vitrage extérieur collé, elle pourrait recevoir tout autre type de remplissage, soit avec parclose extérieur, soit avec serre-vitres et capots etc.. Par ailleurs, l'ossature et les cadres, qui sont d'un type connu dans la technique, ne seront pas décrits en détail, pas plus que leur mode d'assemblage.The accompanying drawings illustrate a form of implementation of the invention. They have no limiting character and if, in particular, the structure shown comprises a filling of the glued exterior glazing, it could receive any other type of filling, either with exterior glazing bead, or with window clamps and hoods, etc. Furthermore , the frame and the frames, which are of a type known in the art, will not be described in detail, any more than their method of assembly.

Sur ces dessins :

  • La figure 1 est une coupe verticale partielle selon la ligne I-I de la figure 2 ;
  • La figure 2 est une coupe horizontale partielle suivant la ligne II-II de la figure 1.
In these drawings:
  • Figure 1 is a partial vertical section along line II of Figure 2;
  • Figure 2 is a partial horizontal section along the line II-II in Figure 1.

Sur les dessins, on distingue deux parties de cadres 1 et 2 superposées, entrant dans la constitution de l'ossature de la façade à étanchéifier, dont on distingue les vitrages, respectivement des vitrages doubles 3 et des vitrages simples 4.In the drawings, there are two parts of frames 1 and 2 superimposed, forming part of the framework of the facade to be sealed, of which there are glazings, respectively double glazing 3 and single glazing 4.

L'espace 5 entre vitrages contigus est ouvert à l'atmosphère, de sorte que les intempéries peuvent pénétrer vers l'ossature constituée par les cadres suivant la flèche F1 de la figure 1.The space 5 between adjoining panes is open to the atmosphere, so that bad weather can penetrate towards the framework constituted by the frames according to arrow F 1 in FIG. 1.

Pour assurer l'étanchéité primaire, un joint 6 en élastomère est disposé verticalement, en arrière de la façade.To ensure primary sealing, an elastomer seal 6 is arranged vertically, behind the facade.

Un second joint 7, également en élastomère, comprend une partie 7a, disposée verticalement à l'arrière du joint 6, qui est repliée sur elle-même de manière à coiffer une partie verticale en saillie 8 du cadre inférieur 2 et à être pincée entre cette partie 8 et les parois latérales du logement 9 du cadre 1 dans laquelle elle est engagée. Cette partie 7a du joint 7 assure ainsi une étanchéité secondaire à l'arrière du joint 6.A second seal 7, also made of elastomer, comprises a part 7 a , arranged vertically behind the seal 6, which is folded back on itself so as to cover a vertical projecting part 8 of the lower frame 2 and to be pinched between this part 8 and the side walls of the housing 9 of the frame 1 in which it is engaged. This part 7a of the gasket 7 ensures a secondary seal to the rear of the joint 6.

Elle comporte a sa surface des ailettes en saillie destinées à être comprimées entre le corps de cette partie 7a et les parois de l'évidement 9, pour assurer l'étanchéité et éviter tout désengagement de la partie 7a.It has, on its surface, projecting fins intended to be compressed between the body of this part 7 a and the walls of the recess 9, in order to seal and avoid any disengagement of the part 7 a .

Celle-ci se prolonge entre le joint 6 et la façade par une partie sensiblement horizontale 7b, formant bavette, à laquelle est attenante et qui est interposée entre les cadres 1 et 2. Les infiltrations d'eau à l'arrière du joint 7 sont ainsi recueillies par la partie 7a et évacuées par celle-ci sur la bavette 7b, suivant la flèche F2 (Figure 2) en direction de la façade, pour être recueillies et être évacuées vers l'extérieur en 10.This extends between the joint 6 and the facade by a substantially horizontal part 7b , forming a flap, to which is attached and which is interposed between the frames 1 and 2. Water infiltration at the rear of the joint 7 are thus collected by the part 7 a and evacuated by the latter on the flap 7 b , along the arrow F 2 (FIG. 2) in the direction of the facade, to be collected and to be evacuated towards the outside at 10.

Le système d'étanchéité conforme à l'invention utilise donc un plan d'étanchéité décalé vers l'intérieur du bâtiment, l'eau pouvant ainsi pénétrer entre les structures de cadres, à la verticale, et étant réévacuée vers l'extérieur à chaque jonction verticale de cadres.The sealing system according to the invention therefore uses a sealing plane offset towards the interior of the building, the water thus being able to penetrate between the frame structures, vertically, and being re-evacuated towards the exterior each time vertical junction of frames.

Comme indiqué ci-dessus, on notera que l'utilisation d'un joint primaire et d'un joint secondaire, c'est-à-dire de deux barrières d'étanchéité, a pour avantage de pouvoir équilibrer entre les deux barrières les différences de pression existant entre l'intérieur et l'extérieur du bâtiment.As indicated above, it will be noted that the use of a primary seal and a secondary seal, that is to say of two sealing barriers, has the advantage of being able to balance the differences between the two barriers. of pressure existing between the interior and exterior of the building.

On notera enfin que le système d'étanchéité conforme à l'invention permet une libre dilatation horizontale et verticale des cadres, ce que ne permettent pas habituellement les systèmes antérieurs.Finally, it should be noted that the sealing system according to the invention allows free horizontal and vertical expansion of the frames, which the prior systems do not usually allow.
