Description

La présente invention concerne un châssis verrier coupe-feu et pare-flammes à tenue au feu modulable devant être installé dans des constructions susceptibles d'assurer pendant une durée déterminée la protection des biens ou des personnes contre le feu.The present invention relates to a fire-resistant glass and flame-resistant chassis with modular fire resistance, which must be installed in constructions capable of ensuring the protection of property or people against fire for a determined period.

Il existe actuellement des châssis coupe-feu susceptibles de résister à des températures de l'ordre de 1000°C pendant une durée maximale d'une heure et demie avant de se déformer en protubérance vers le feu, de se dégager des parcloses qu'ils déforment pour tomber et cesser alors de remplir leur fonction coupe-feu. Ces châssis coupe-feu présentent un certain nombre d'inconvénients tels que leur absence de modularité pour permettre des tenues au feu de durée variable, leur incapacité à s'intégrer dans de grands ensembles vitrés sans inclure un minimum de maçonnerie, leur difficile mise en oeuvre. En effet, généralement, l'assemblage du châssis, des joints et la pose des volumes verriers très lourds, sont effectués en altitude, de l'extérieur du bâtiment, dans des conditions de sécurité souvent précaires. Ce montage s'effectue avec des moyens de manutention très lourds (grue, nacelle élévatrice) d'une précision aléatoire en regard de la minutie et de la précision exigées par le produit verrier à installer.There are currently fire-resistant frames capable of withstanding temperatures of the order of 1000 ° C for a maximum period of an hour and a half before deforming in protrusion towards the fire, freeing themselves from the glazing beads which they deform to fall and then stop fulfilling their firebreak function. These fire-resistant frames have a certain number of drawbacks such as their lack of modularity to allow fire resistance of variable duration, their inability to integrate into large glazed units without including a minimum of masonry, their difficult implementation. artwork. Indeed, generally, the assembly of the frame, the seals and the installation of very heavy glass volumes, are carried out at altitude, from outside the building, in often precarious security conditions. This assembly is carried out with very heavy handling means (crane, lifting platform) of random precision with regard to the thoroughness and precision required by the glass product to be installed.

Le but de la présente invention est donc de proposer un châssis coupe-feu exempt des inconvénients précités qui soit rapide à installer sur des surfaces importantes tout en offrant une tenue au feu importante dans le temps.The object of the present invention is therefore to propose a fire-resistant chassis free from the aforementioned drawbacks which is quick to install on large surfaces while offering significant resistance to fire over time.

L'invention concerne à cet effet un châssis verrier coupe-feu et pare-flammes à tenue au feu modulable, devant être installé dans un support généralement en maçonnerie, du type comprenant une ossature rigide périphérique de maintien d'un ensemble verrier modulable constitué d'au moins un groupe multicouche de panneaux de verre séparés entre eux par des lames d'air, caractérisé en ce que le châssis est solidarisé au support généralement en maçonnerie par l'intermédiaire d'un précadre périphérique préalablement fixé à l'intérieur du support maçonnerie, ledit précadre comportant des moyens de fixation tels que des lumières oblongues qui coopèrent avec des moyens de fixation de l'ossature tels que des plots de positionnement pour assurer d'une part une immobilisation transversale, d'autre part une libre dilatation longitudinale et verticale de l'ossature par rapport au précadre.To this end, the invention relates to a fire-rated glass and flame-retardant frame with modular fire resistance, to be installed in a support generally made of masonry, of the type comprising a rigid peripheral framework for holding a modular glass assembly consisting of '' at least one multilayer group of glass panels separated from each other by air knives, characterized in that the frame is secured to the support, generally in masonry, by means of a peripheral pre-frame previously fixed inside the support masonry, said pre-frame comprising fixing means such as oblong openings which cooperate with means for fixing the framework such as positioning studs to ensure on the one hand a transverse immobilization, on the other hand a free longitudinal expansion and vertical of the frame with respect to the pre-frame.

Selon une forme de réalisation préférée de l'invention, les montants du précadre périphérique affectent la forme d'un L, l'une des branches venant en appui contre le support de maçonnerie pour être fixée à ce dernier, la branche perpendiculaire recevant par appui l'ossature périphérique du volume verrier et l'ossature périphérique rigide du volume verrier modulable est formée d'une semelle métallique formant cadre obtenue par tronçonnage puis assemblage de profilés métalliques plans, sur la face intérieure de laquelle est préfixé un profilé de section généralement carrée destiné à coopérer avec un deuxième profilé venant se fixer sur cette même face intérieure après insertion d'un volume verrier modulable et de ses moyens d'étanchéité thermique internes de manière à enserrer le volume verrier et assurer son maintien dans l'ossature et sa résistance aux températures élevées.According to a preferred embodiment of the invention, the amounts of the peripheral pre-frame assume the shape of an L, one of the branches bearing against the masonry support to be fixed to the latter, the perpendicular branch receiving by support the peripheral frame of the glass volume and the rigid peripheral frame of the modular glass volume is formed by a metal sole forming a frame obtained by cutting up and then assembling flat metal profiles, on the inner face of which is generally fixed a profile of square section intended to cooperate with a second profile coming to be fixed on this same internal face after insertion of a modular glass volume and its internal thermal sealing means so as to enclose the glass volume and ensure its maintenance in the frame and its resistance to high temperatures.

Conformément aux figures 1 et 9, le châssis verrier coupe-feu, objet de l'invention, comprend une ossature périphérique rigide 5 généralement en métal 6, 7, 8 formant cadre et maintenant un volume verrier 9 modulable en fonction de la tenue au feu désirée. L'ensemble ossature 5 et volume verrier 9 une fois assemblé vient se loger à l'intérieur d'un précadre périphérique 1 préalablement installé dans un support tel qu'une baie 4 généralement en maçonnerie dont les dimensions et le positionnement sont fonction de la construction envisagée et de son application (locaux d'essai au feu, salles de contrôle d'usines, espaces d'exposition d'objets, etc).In accordance with FIGS. 1 and 9, the fire-rated glass frame, object of the invention, comprises a rigid peripheral frame 5 generally made of metal 6, 7, 8 forming a frame and maintaining a glass volume 9 which can be adjusted as a function of fire resistance desired. The frame 5 and glass volume 9 assembly once assembled is housed inside a peripheral frame 1 previously installed in a support such as a bay 4 generally made of masonry, the dimensions and positioning of which depend on the construction envisaged and its application (fire test rooms, factory control rooms, object exhibition spaces, etc.).

Le précadre 1 est fixé à l'intérieur de la baie soit au moment de la réalisation du béton au moyen d'un mannequin de positionnement destiné à garantir ses dimensions, soit fixé sur la baie après réalisation du béton et vérification des dimensions de ladite baie. Ce précadre 1 est, dans une forme de réalisation préférée de l'invention, constitué de montants généralement en acier affectant la forme d'un L, l'une des branches 3 du L venant en appui contre la baie maçonnée 4 pour être fixée à cette dernière au moyen par exemple de chevilles 15, la branche perpendiculaire 2 recevant par appui l'ossature périphérique 5 du volume verrier 9 comme le montre la figure 9. Généralement entre cette ossature périphérique 5 et le précadre 1, on interpose une bande isolante 14.The pre-frame 1 is fixed inside the bay either at the time of the concrete production by means of a positioning dummy intended to guarantee its dimensions, or fixed on the bay after making the concrete and checking the dimensions of said bay . This pre-frame 1 is, in a preferred embodiment of the invention, consisting of uprights generally of steel affecting the shape of an L, one of the branches 3 of the L coming to bear against the masonry opening 4 to be fixed to the latter by means of, for example, dowels 15, the perpendicular branch 2 receiving by support the peripheral framework 5 of the glass volume 9 as shown in FIG. 9. Generally between this peripheral framework 5 and the frame 1, an insulating strip 14 is interposed .

L'ossature périphérique rigide 5 du volume verrier 9, modulable suivant l'épaisseur du volume verrier monobloc utilisé et encadrant celui-ci est, quant à elle, constituée, comme le montrent les figures 3 et 6, d'une semelle métallique 8 formée par exemple de tronçons coupés à longueur dans une barre méplate sur la face intérieure de laquelle on fixe par exemple par soudure une parclose 6 coupée en morceaux à longueur dans une barre métallique de section sensiblement carrée, l'ensemble 6, 8 étant assemblé par des moyens appropriés pour former un cadre à l'intérieur duquel est inséré le volume verrier qui est immobilisé en position au moyen d'une parclose supplémentaire 7 rapportée et fixée par exemple au moyen d'une vis 16 sur la semelle 8. De ce fait, les parcloses 6 et 7 enserrent le volume verrier 9 en le maintenant en position. Bien évidemment, il peut être inséré entre le volume verrier et l'ossature périphérique 5 des moyens d'isolation comme cela sera décrit ci-après.The rigid peripheral frame 5 of the glass volume 9, which can be adjusted according to the thickness of the one-piece glass volume used and surrounding it, for its part, consists, as shown in FIGS. 3 and 6, of a metal sole 8 formed for example of sections cut to length in a flat bar on the inner face of which is fixed for example by welding a glazing bead 6 cut into pieces to length in a metal bar of substantially square section, the assembly 6, 8 being assembled by suitable means for forming a frame within which is inserted the glass volume which is immobilized in position by means of an additional glazing bead 7 attached and fixed for example by means of a screw 16 on the sole 8. Therefore, glazing beads 6 and 7 enclose the glass volume 9 by now in position. Obviously, it can be inserted between the glass volume and the peripheral framework 5 of the isolation means as will be described below.

Le volume verrier 9 est, comme le montre en particulier la figure 1, constitué d'au moins un groupe multicouche 11 (dans l'exemple représenté, au nombre de trois), chaque groupe comprenant une série de panneaux de verre disposés parallèles solidarisés périphériquement chez le miroitier avec un intercalaire ou une entretoise 10 entre chaque vitre et entre chaque groupe multicouche. Grâce à cette conception, on choisit en fonction du nombre de groupes multicouches utilisés la durée de résistance au feu du volume verrier. Une fois constitué, ce volume verrier 9 est inséré dans son ossature périphérique 5 en intercalant entre le volume verrier 9 et l'ossature 5, comme le montre la figure 1, une première bande de matériau isolant 12 semi-rigide de l'ordre de 3 mm d'épaisseur destinée au rattrapage d'écarts dimensionnels, cette bande 12 étant posée sur une plaque de répartition en matériau isolant rigide 13 d'une épaisseur de l'ordre de 5 mm. Complétée par l'utilisation de joints silicone 24, cette disposition de matériaux isolants permet d'empêcher la déformation de l'ossature périphérique 5 du châssis. Grâce à une telle conception, il est possible d'avoir toute une gamme de châssis à tenue au feu variable dont les éléments constitutifs sont standardisés. Il suffit pour ce faire de disposer d'une série de semelles 8, de plaques d'isolant 12 et 13 et de précadres 1 de largeurs variables standardisées par rapport aux épaisseurs du volume verrier 9.The glass volume 9 is, as shown in particular in Figure 1, consisting of at least one multilayer group 11 (in the example shown, three in number), each group comprising a series of glass panels arranged parallel secured peripherally in the mirror shop with a spacer or spacer 10 between each window and between each multilayer group. Thanks to this design, depending on the number of multilayer groups used, the duration of fire resistance of the glass volume is chosen. Once constituted, this glass volume 9 is inserted into its peripheral framework 5 by interposing between the glass volume 9 and the framework 5, as shown in FIG. 1, a first strip of semi-rigid insulating material 12 of the order of 3 mm thick intended to compensate for dimensional deviations, this strip 12 being placed on a distribution plate made of rigid insulating material 13 with a thickness of the order of 5 mm. Complemented by the use of silicone seals 24, this arrangement of insulating materials makes it possible to prevent the deformation of the peripheral framework 5 of the chassis. Thanks to such a design, it is possible to have a whole range of chassis with variable fire resistance, the constituent elements of which are standardized. To do this, it suffices to have a series of soles 8, insulating plates 12 and 13 and pre-frames 1 of variable widths standardized with respect to the thicknesses of the glass volume 9.

Une fois le volume verrier 9 disposé dans l'ossature périphérique 5 et maintenu en position par fixation de place en place de la parclose 7, il convient d'installer l'ensemble dans le précadre périphérique 1 lui-même déjà installé dans le support maçonnerie 4. Il est à noter que le positionnement du volume verrier dans son ossature périphérique 5 s'effectue généralement en atelier ou sur le chantier, comme le montre la figure 8, en installant une partie de l'ossature périphérique 5 sur des chevalets 28 puis en installant le volume verrier à l'intérieur de l'ossature et en venant fixer la parclose amovible 7. Par la suite, à l'aide de moyens de levage appropriés, on dispose l'ossature périphérique 5 munie du volume verrier 9 dans le précadre périphérique 1 comme le montre la figure 9. Dans ce cas, l'ossature périphérique 5 comporte dans sa partie basse un plot de positionnement ou de centrage 20 faisant saillie de l'ossature et susceptible de pénétrer à l'intérieur d'une lumière oblongue 19 ménagée dans l'aile 3 du précadre périphérique 1 comme le montre la figure 6. Cette lumière oblongue 19 est orientée de manière à immobiliser transversalement l'ossature périphérique à l'intérieur du précadre 1 et à permettre un jeu longitudinal de ce dernier.Once the glass volume 9 is disposed in the peripheral framework 5 and held in position by fixing from place to place of the glazing bead 7, the assembly should be installed in the peripheral frame 1 itself already installed in the masonry support 4. It should be noted that the positioning of the glass volume in its peripheral framework 5 is generally carried out in the workshop or on the site, as shown in FIG. 8, by installing part of the peripheral framework 5 on easels 28 then by installing the glass volume inside the framework and by fixing the removable glazing bead 7. Subsequently, using appropriate lifting means, the peripheral framework 5 is provided with the glass volume 9 in the peripheral frame 1 as shown in FIG. 9. In this case, the peripheral framework 5 comprises in its lower part a positioning or centering stud 20 projecting from the framework and capable of penetrating inside an oblong opening 19 made in the wing 3 of the peripheral precadre 1 as shown in FIG. 6. This oblong opening 19 is oriented so as to immobilize the peripheral framework transversely inside of frame 1 and allow a longitudinal play of the latter.

Dans certains cas, il est nécessaire d'insérer entre la semelle 8 de l'ossature périphérique 5 et l'aile 3 du précadre 1 une plaque de calage intermédiaire 21 comme le montre la figure 6. Une fois le pion 20 introduit dans la lumière 19, il suffit de continuer à exercer une poussée sur le châssis, comme le montre la figure 9, pour que l'ossature périphérique 5 vienne complètement se loger dans le précadre périphérique 1. En partie haute, l'ossature périphérique 5 est solidarisée au précadre périphérique 1 au moyen d'une vis 18 traversant une lumière oblongue 17 ménagée dans l'aile 3 du précadre périphérique 1 et venant se visser dans la parclose 7 de l'ossature 5 du châssis. Grâce à l'orientation de cette lumière oblongue 17, comme le montre la figure 4, l'ossature périphérique 5 est immobilisée transversalement mais est libre verticalement et généralement longitudinalement à l'intérieur du précadre 1. Pour parfaire l'assemblage sur un plan esthétique, il convient de disposer des capotages symétriques en forme de L, généralement en tôle laquée, de part et d'autre du volume verrier 9, de manière à enchâsser ce dernier au niveau de l'ossature périphérique 5 comme le montre la figure 1. Les deux extrémités de ce capotage sont pliées en équerre puis pliées à nouveau en biais selon un pli 23 terminé par un épaulement qui vient se clipper élastiquement sous l'épaulement des organes de fixation, généralement des vis, qui assurent la fixation des parcloses sur la semelle. A l'autre extrémité de l'autre branche du L, les capots sont clippés de la même manière sous la tête de vis qui solidarise le précadre périphérique 1 à la semelle 8. Cette branche du L vient en appui contre la baie maçonnée 4. Ces capotages sont ensuite bourrés d'un matériau isolant.In some cases, it is necessary to insert between the sole 8 of the peripheral framework 5 and the wing 3 of the preadframe 1 an intermediate wedging plate 21 as shown in Figure 6. Once the pin 20 introduced into the light 19, it suffices to continue to exert a push on the chassis, as shown in FIG. 9, so that the peripheral framework 5 comes to be completely housed in the peripheral frame 1. In the upper part, the peripheral framework 5 is secured to the peripheral pre-frame 1 by means of a screw 18 passing through an oblong slot 17 formed in the wing 3 of the peripheral pre-frame 1 and being screwed into the glazing bead 7 of the frame 5 of the chassis. Thanks to the orientation of this oblong lumen 17, as shown in FIG. 4, the peripheral framework 5 is immobilized transversely but is free vertically and generally longitudinally inside the pre-frame 1. To perfect the assembly on an aesthetic level , symmetrical L-shaped covers, generally made of lacquered sheet metal, should be placed on either side of the glass volume 9, so as to embed the latter at level of the peripheral framework 5 as shown in FIG. 1. The two ends of this cowling are folded at right angles and then folded again at an angle according to a fold 23 terminated by a shoulder which is clipped elastically under the shoulder of the bodies of fixing, generally screws, which ensure the fixing of the glazing beads on the sole. At the other end of the other branch of the L, the covers are clipped in the same way under the screw head which secures the peripheral frame 1 to the sole 8. This branch of the L comes to bear against the masonry opening 4. These cowls are then stuffed with an insulating material.

Dans le cas d'un positionnement de deux châssis côte-à-côte dans un précadre périphérique 1 comme le montre la figure 2, il devient nécessaire d'utiliser un précadre intermédiaire 25 pour séparer les deux châssis contigus solidarisables au même précadre périphérique. En général, dans ce cas, comme le montre la figure 5, le précadre intermédiaire 25 affecte la forme d'un T dont la branche 26 perpendiculaire aux ailes constitue le moyen de séparation entre deux semelles constitutives des ossatures périphériques 5 des volumes verriers 9. Dans ce cas, la branche de ce T est enserrée par les faces externes des semelles 8. Quant aux ailes du T, elles jouent un rôle analogue à l'aile 2 du précadre périphérique 1.In the case of positioning two frames side by side in a peripheral frame 1 as shown in FIG. 2, it becomes necessary to use an intermediate frame 25 to separate the two contiguous frames which can be joined to the same peripheral frame. In general, in this case, as shown in FIG. 5, the intermediate pre-frame 25 takes the form of a T whose branch 26 perpendicular to the wings constitutes the means of separation between two flanges constituting the peripheral frameworks 5 of the glass volumes 9. In this case, the branch of this T is enclosed by the external faces of the soles 8. As for the wings of the T, they play a role analogous to the wing 2 of the peripheral frame 1.

De la même manière que décrit précédemment, il est nécessaire d'utiliser des capotages pour parfaire l'esthétisme du produit. Ces capotages affectent dans ce cas la forme d'un U comme le montre la figure 5 dans laquelle ils sont désignés par la référence 27.In the same way as described above, it is necessary to use cowlings to perfect the aesthetics of the product. These cowlings in this case assume the shape of a U as shown in FIG. 5 in which they are designated by the reference 27.
