Description

La présente invention concerne une fenêtre à capacité de résistance au feu accrue faite d'au moins un vitrage en verre silicaté et un châssis dans lequel le vitrage en verre silicaté est monté avec intercalation d'une couche de mastic résistant à la chaleur, à conductibilité thermique accrue, entre au moins une face du vitrage et la parclose de retenue en métal associée.The present invention relates to a window with increased fire resistance capacity made of at least one silicate glass pane and a frame in which the silicate glass pane is mounted with the insertion of a layer of heat-resistant, conductive mastic. increased thermal, between at least one face of the glazing and the associated metal retaining bead.

Dans une telle fenêtre apte à résister au feu, décrite dans le brevet français 2 232 666, la parclose est telle qu'elle transmet aux bords du vitrage la chaleur qu'elle reçoit permettant ainsi audit vitrage de s'échauffer pratiquement simultanément sur l'ensemble de sa surface, bords y compris. Le gradient de température entre la zone centrale.et les bords étant ainsi diminué, les tensions résultant de l'écart de température et qui sont normalement la cause du bris des vitrages, ne se créent pas.In such a window capable of withstanding fire, described in French Patent 2,232,666, the glazing bead is such that it transmits the heat it receives to the edges of the glazing, thereby enabling said glazing to heat up practically simultaneously on the entire surface, including edges. The temperature gradient between the central zone and the edges being thus reduced, the tensions resulting from the temperature difference and which are normally the cause of glass breakage, are not created.

Il s'est avéré que des fenêtres de cette construction connue présentent une capacité de résistance au feu accrue, mais l'allongement de la durée de résistance au feu ne suffit pas encore pour permettre la classification de la fenêtre dans une des classes de résistances au feu de la norme DIN 4102. Il a par conséquent été proposé d'utiliser d'autres châssis : des châssis qui laissent libres en permanence les bords du vitrage (brevets français 2 314 993 et 2 282 033) ou des châssis qui dégagent ces bords seulement au moment d'un incendie (brevet français 2 366 434) permettant ainsi le même échauffement des bords et de la zone centrale du vitrage.Windows of this known construction have been found to have increased fire resistance, but the extension of the fire resistance duration is not yet sufficient to allow the classification of the window in one of the fire resistance classes of standard DIN 4102. It has therefore been proposed to use other frames: frames which permanently leave the edges of the glazing free (French patents 2,314,993 and 2,282,033) or frames which release these edges only at the time of a fire (French patent 2,366,434) thus allowing the same heating of the edges and of the central area of the glazing.

De telles fenêtres présentent certes des propriétés de résistance au feu suffisantes pour une classification selon la norme DIN 4102, mais elles exigent cependant des châssis particuliers assez compliqués.Such windows certainly have sufficient fire resistance properties for classification according to DIN 4102, but they however require rather complicated particular frames.

On connaît également une fenêtre apte à résister au feu dans laquelle un vitrage en verre silicaté est monté dans un châssis métallique avec intercalation d'une couche résistant à la chaleur, comme de l'amiante, et dans laquelle le vitrage est pourvu, sur sa surface le long de ses bords, d'une couche d'émail absorbant le rayonnement calorifique, couche qui de préférence se prolonge sur le cadre et déborde dans la zone centrale du vitrage non recouvert par le cadre (brevet belge 886 277). Cette couche d'émail doit assurer dans la zone des bords une absorption renforcée de la chaleur et ainsi une diminution du gradient de température entre le bord et le centre. L'inconvénient de cette réalisation réside dans le fait que chaque vitrage après sa découpe, doit recevoir la couche d'émail de pourtour qui, le cas échéant, doit être cuite par un traitement thermique ultérieur. De plus, cette bordure émaillée est gênante et rétrécit le champ de vision.A window capable of withstanding fire is also known in which a silicate glass glazing is mounted in a metal frame with an interlayer of a heat-resistant layer, such as asbestos, and in which the glazing is provided, on its surface along its edges, of a layer of enamel absorbing the heat radiation, layer which preferably extends on the frame and overflows in the central zone of the glazing not covered by the frame (Belgian patent 886 277). This layer of enamel must ensure in the edge area enhanced absorption of heat and thus a decrease in the temperature gradient between the edge and the center. The disadvantage of this embodiment lies in the fact that each glazing after its cutting, must receive the layer of perimeter enamel which, if necessary, must be fired by a subsequent heat treatment. In addition, this enamel border is annoying and narrows the field of vision.

L'invention a pour but de procurer une fenêtre à durée de résistance au feu accrue d'une manière répondant aux exigences de la norme DIN 4102, pour laquelle on puisse utiliser des châssis courants et pour laquelle niile chassis, ni le vitrage n'exigent des mesures inhabituelles pour garantir l'échauffement souhaité des bords du vitrage.The invention aims to provide an increased fire resistance time window in a manner that meets the requirements of DIN 4102, for which we can use current frame and for which neither the frame i, or the glazing n 'require unusual measures to ensure the desired heating of the edges of the glazing.

L'invention réside dans le fait que la couche thermoconductrice prévue entre le vitrage et la parclose métallique associée est en un mélange d'une matière de matière plastique résistant à la chaleur à plasticité permanente ou à élasticité permanente et d'un granulat d'un métal bon conducteur de la chaleur ou d'un semi-conducteur d'une granulométrie d'environ 0,05 à 1,5 mm. Avantageusement la parclose est en outre pourvue à sa face externe d'un revêtement absorbant.The invention lies in the fact that the thermally conductive layer provided between the glazing and the associated metal glazing bead is made of a mixture of a heat-resistant plastic material with permanent plasticity or with permanent elasticity and an aggregate of a metal that is a good conductor of heat or a semiconductor with a particle size of approximately 0.05 to 1.5 mm. Advantageously, the glazing bead is further provided on its outer face with an absorbent coating.

Il s'est avéré de manière étonnante qu'une amélioration sensible des propriétés de résistance au feu est obtenue grâce aux mesures relativement simples de l'invention. Les mesures nécessaires conformément à l'invention peuvent être utilisées dans la pratique pour toutes les constructions de châssis métalliques courantes, et, le cas échéant, même pour des châssis en bois. Elles n'exigent pas non plus de traitement supplémentaire de la feuille de verre, tout au plus un certain façonnage des bords pour éliminer les défauts de découpe qui peuvent constituer des amorces de rupture, de telle sorte que l'on puisse, par conséquent, réaliser de la manière la plus simple, des vitrages aptes à résister au feu.It has surprisingly been found that a significant improvement in the fire resistance properties is obtained thanks to the relatively simple measures of the invention. The measures required in accordance with the invention can be used in practice for all common metal frame constructions, and, if necessary, even for wooden frames. They also do not require additional treatment of the glass sheet, at most a certain shaping of the edges in order to eliminate the cutting defects which can constitute incipient fractures, so that one can, consequently, create in the simplest way, glazing capable of withstanding fire.

La couche intermédiaire thermoconductrice est mise en place d'une manière particulièrement avantageuse sous la forme d'une bande profilée préfabriquée entre le châssis et le vitrage et est pressée par la parclose contre le vitrage comme une bande normale de mastic. Ces bandes profilées peuvent présenter n'importe quelle section adéquate. Elles peuvent, en outre, être pourvues, sur la surface adjacente au vitrage et/ou sur la surface adjacente à la parclose, d'une couche d'adhésif, avantageusement d'un adhésif également résistant à la chaleur et thermoconducteur, pour garantir également, en cas d'incendie, un contact sûr entre les surfaces adjacentes et ainsi une bonne transmission de chaleur au vitrage.The thermally conductive intermediate layer is placed in a particularly advantageous manner in the form of a prefabricated profiled strip between the frame and the glazing and is pressed by the glazing bead against the glazing like a normal strip of mastic. These profiled strips can have any suitable section. They can also be provided, on the surface adjacent to the glazing and / or on the surface adjacent to the glazing bead, with a layer of adhesive, advantageously an adhesive which is also heat resistant and thermally conductive, to also guarantee , in the event of a fire, secure contact between adjacent surfaces and thus good heat transmission to the glazing.

The invention will be described below in more detail with reference to the accompanying drawings, in which:

La couche thermoconductrice se trouvant entre le vitrage et la parclose associée peut avoir la forme d'une masse très visqueuse et peut être introduite, par exemple, à l'aide d'un outil d'extrusion ou d'un pistolet approprié dans l'interstice séparant la parclose du vitrage. Des bandes profilées 1, 2 ou 3 à élasticité permanente de section transversale rectangulaire, en L ou en U, telles qu'elles sont représentées sur les figures 1 à 3, sont cependant avantageusement préparées préalablement.The thermally conductive layer between the glazing and the associated glazing bead can have the form of a very viscous mass and can be introduced, for example, using an extrusion tool or a suitable gun into the gap separating the glazing bead. However, advantageously prepared strips 1, 2 or 3 with permanent elasticity of rectangular cross-section, in L or in U, as shown in FIGS. 1 to 3.

La matière d'étanchéité visqueuse thermoconductrice ou les bandes préformées 1, 2, 3 sont constituées en principe d'un mélange d'une masse résistant à la chaleur à élasticité ou à plasticité permanente à base de silicone ou de caoutchouc et d'un ganulat métallique qui sont mélangés en des proportions de 0,5 à 4 parties en poids de granulat métallique pour 1 partie en poids de masse à plasticité ou à élasticité permanente.The viscous thermally conductive sealing material or the preformed strips 1, 2, 3 consist in principle of a mixture of a heat-resistant mass with elasticity or permanent plasticity based on silicone or rubber and a ganulate metallic which are mixed in proportions of 0.5 to 4 parts by weight of metallic aggregate for 1 part by weight of mass with plasticity or permanent elasticity.

- On peut optimiser les résultats du point de vue de la transmission de la chaleur et de la plasticité ou de l'élasticité de la masse d'étanchéité si le granulat métallique et la matière plastique sont mélangés dans des proportions en poids d'environ 2,5:1.- The results can be optimized from the point of view of heat transmission and the plasticity or elasticity of the sealing mass if the metallic aggregate and the plastic are mixed in weight proportions of about 2 , 5: 1.

A titre de masse résistant à la chaleur à élasticité ou à plasticité permanente, le produit préparé à partir d'organosiloxanes EGO-SILKON-B 1 de la société EGO-Dichtstoffwerke GmbH Co dont le siège se trouve à Munich, a donné satisfaction. A titre de masse plastique pour la matière d'étanchéité thermoconductrice, le mastic résistant à la chaleur commercialisé sous la dénomination PYROSIL WEISS 13 11 79/53 de la société PERENNATORWERK Alfred Hagen GmbH de Wiesbaden a également donné satisfaction.As a heat-resistant mass with elasticity or permanent plasticity, the product prepared from organosiloxanes EGO-SILKON-B 1 from the company EGO-Dichtstoffwerke GmbH Co with headquarters in Munich, has given satisfaction. As plastic mass for the thermally conductive sealing material, the heat-resistant sealant sold under the name PYROSIL WEISS 13 11 79/53 from the company PERENNATORWERK Alfred Hagen GmbH of Wiesbaden has also given satisfaction.

A titre de composant thermoconducteurs dans la matière d'étanchéité, on peut utiliser des granulats de métaux présentant une bonne conductibilité thermique, en particulier du cuivre ou de l'aluminium, et, en règle générale, pour des raisons de prix, on donne la préférence à l'aluminium. Le granulat doit être formé de grains présentant une granulométrie de 0,05 à 1,5 mm, des valeurs optimales étant atteintes lorsque la granulométrie est comprise entre 0,3 et 0,8 mm. Au lieu d'un granulat en un métal bon conducteur de la chaleur, on peut aussi utiliser un granulat présentant environ la même granulométrie, mais fait d'un semi-conducteur bon conducteur de la chaleur, comme par exemple du graphite.As a thermally conductive component in the sealing material, it is possible to use aggregates of metals having good thermal conductivity, in particular copper or aluminum, and, as a general rule, for price reasons, the preferably aluminum. The aggregate must be formed of grains having a particle size of 0.05 to 1.5 mm, optimal values being reached when the particle size is between 0.3 and 0.8 mm. Instead of an aggregate made of a metal which is a good conductor of heat, it is also possible to use an aggregate having approximately the same particle size, but made of a semiconductor which is a good conductor of heat, such as for example graphite.

Selon le domaine d'utilisation souhaité, on emploie pour le mélange, des masses plastiques qui restent plastiques et peuvent être manipulées sur le chantier de construction ou lors de la fabrication de la fenêtre, ou bien des produits qui peuvent être extrudés sous forme de cordons présentant la section souhaitée et qui durcissent ensuite ou polymérisent au point qu'ils puissent être appliqués sous la forme de bandes profilées élastiques.Depending on the desired field of use, plastic materials are used for the mixture which remain plastic and can be handled on the construction site or during the manufacture of the window, or else products which can be extruded in the form of beads. having the desired cross-section and which then harden or polymerize to the point that they can be applied in the form of elastic profiled strips.

Comme le montre la figure 1, la bande d'étanchéité thermoconductrice 1 est constituée d'une âme centrale 4 qui peut être pourvue d'une mince couche d'adhésif 5 sur ses deux surfaces venant en contact avec le vitrage et avec la parclose. L'adhésif utilisé à cet effet doit également être préparé à partir d'un silicone résistant à la chaleur et ne doit pas perdre son adhésivité et sa conductibilité thermique sous l'effet de la chaleur. L'épaisseur de sa couche doit être la plus faible possible, de préférence elle ne doit être que de quelques microns, de telles sorte que la transmission de la chaleur de la parclose-à la bande d'étanchéité puis de la bande d'étanchéité au vitrage soit le moins possible interrompue.As shown in Figure 1, the thermally conductive sealing strip 1 consists of a central core 4 which can be provided with a thin layer of adhesive 5 on its two surfaces coming into contact with the glazing and with the glazing bead. The adhesive used for this purpose must also be prepared from a heat-resistant silicone and must not lose its adhesiveness and thermal conductivity under the effect of heat. The thickness of its layer should be as small as possible, preferably it should only be a few microns, so that the transmission of heat from the glazing bead to the sealing strip and then from the sealing strip glazing is interrupted as little as possible.

Les figures 4 à 7 illustrent plusieurs exemples de fenêtres conformes à l'invention, et montrent chaque fois une coupe de la partie inférieure d'un châssis de fenêtre. Il va de soi que le chassis de fenêtre possède sur tout le pourtour la même structure que celle qui est représentée sur les dessins.Figures 4 to 7 illustrate several examples of windows according to the invention, and each time show a section of the lower part of a window frame. It goes without saying that the window frame has around the entire periphery the same structure as that shown in the drawings.

La fenêtre conforme à l'invention, dans sa construction la plus simple avec un vitrage formé d'une seule vitre, est représentée sur la figure 4. La vitre 8 est en un verre à faible coefficient de dilatation thermique, en particuier un verre borosilicaté. Dans le cas de l'utilisation d'une telle vitre en verre borosilicaté, une trempe ou une trempe dite de bordure, telle qu'elle est décrite dans le brevet français 2 264 784 n'est même pas nécessaire. Il faut cependant assurer par un façonnage des bords que la résistance des bords du verre ait une valeur suffisamment élevée. Une résistance suffisante des bords est obtenue dans une vitre en verre borosilicaté lorsque la résistance de la vitre à la flexion est d'environ 50 N/mm2 conformément à la norme DIN 52 303. Pour augmenter d'avantage la solidité des bords, on peut également soumettre les vitres en verre borosilicaté à une trempe. Au lieu d'une vitre en verre borosilicaté, on peut aussi utiliser pour la vitre 8 une vitre-en verre Float ayant subi une trempe thermique. A cause du coefficient de dilatation thermique plus élevé du verre Float, il faut dans ce cas que la résistance des bords mesurée conformément à la norme DIN 52 303 soit d'au moins environ 100 N/mm2.The window according to the invention, in its simplest construction with glazing formed from a single pane, is shown in FIG. 4. The pane 8 is made of a glass with a low coefficient of thermal expansion, in particular a borosilicate glass. . In the case of the use of such a borosilicate glass pane, tempering or so-called border tempering, as described in French patent 2,264,784 is not even necessary. However, it must be ensured by shaping the edges that the resistance of the edges of the glass has a sufficiently high value. Sufficient edge resistance is obtained in a borosilicate glass pane when the glass's flexural strength is approximately 50 N / mm 2 in accordance with DIN 52 303. To further increase the strength of the edges, may also subject borosilicate glass panes to tempering. Instead of a borosilicate glass pane, it is also possible to use for pane 8 a Float glass pane having undergone thermal tempering. Because of the higher coefficient of thermal expansion of Float glass, in this case, the edge resistance measured in accordance with DIN 52 303 must be at least about 100 N / mm 2 .

Le chassis de fenêtre comprend un chassis de base 9 ayant la forme d'un profilé d'acier qui peut se présenter comme un tube carré ou comme un profilé de n'importe quelle autre section transversale adéquate, et deux parcloses 10 et 11 qui, pour plus de simplicité, sont représentées comme de simples éléments plats en acier. Au lieu d'un profilé d'acier, le chassis de base 9 peut aussi être fait d'une autre matière, par exemple du bois. Il convient simplement de faire en sorte qu'au moins la parclose qui est disposée du côté exposé à l'action de la chaleur soit en métal. Entre les parcloses 10 et 11 d'une part, et la vitre 8 d'autre part, est insérée une bande d'étanchéité 1 ayant la forme d'une bande allongée d'une épaisseur d'au moins 2 mm. Cette bande d'étanchéité 1, correspondant à la structure de la bande profilée représentée sur la figure 1, est pourvue des deux côtés d'une couche d'adhésif résistant à la chaleur et thermoconductrice et elle est pressée contre la vitre par les parcloses 10, 11. Entre le bord de la vitre 8 et le profilé d'acier 9, est intercalée une couche intermédiaire 12 d'amiante.The window frame comprises a base frame 9 in the form of a steel profile which can be presented as a square tube or as a profile of any other suitable cross section, and two glazing beads 10 and 11 which, for simplicity, are shown as simple flat steel elements. Instead of a steel profile, the base frame 9 can also be made of another material, for example wood. It is simply necessary to ensure that at least the glazing bead which is arranged on the side exposed to the action of heat is made of metal. Between the glazing beads 10 and 11 on the one hand, and the glass 8 on the other hand, a sealing strip 1 having the shape of an elongated strip with a thickness of at least 2 mm is inserted. This sealing strip 1, corresponding to the structure of the profiled strip shown in FIG. 1, is provided on both sides with a layer of heat-resistant and thermally conductive adhesive and it is pressed against the glass by the glazing beads 10 , 11. Between the edge of the window 8 and the steel section 9, an intermediate layer 12 of asbestos is interposed.

En lieu et place de la bande d'étanchéité 1 de section rectangulaire, on peut utiliser d'une manière particulièrement avantageuse une bande d'étanchéité 3 de section en U (figure 3). Cette bande d'étanchéité 3 est avantageusement appliquée sur les bords de la vitre lors de sa préparation après fabrication, c'est-à-dire, le cas échéant, après le traitement des bords ou après la trempe. Elle sert ainsi, pendant le transport et le montage de la vitre, de protection pour les bords et empêche donc des détériorations éventuelles qui pourraient diminuer la résistance des bords et ainsi la résistance au feu.In place of the sealing strip 1 of rectangular section, it is possible to use in a particularly advantageous manner a sealing strip 3 of U-shaped section (FIG. 3). This sealing strip 3 is advantageously applied to the edges of the glass during its preparation after manufacture, that is to say, if necessary, after the treatment of the edges or after tempering. It thus serves, during transport and assembly of the glass, as protection for the edges and therefore prevents possible deterioration which could reduce the resistance of the edges and thus the fire resistance.

Les deux parcloses 10, 11 sont pourvues sur leurs faces externes d'une couche 14 absorbant le rayonnement calorifique. A titre de couche absorbant les rayons calorifiques 14, on peut utiliser, par exemple, un revêtement d'une peinture absorbante qui présente d'une part une capacité d'absorption du rayonnement calorifique accrue et d'autre part une résistance à la chaleur accrue également. Une telle couche de peinture, lors d'un essai de tenue au feu, doit conserver sa capacité d'absorption complète au moins pendant les dix premières minutes après le début de l'essai d'incendie. Le produit de la société Ernst B. Buchner Lackfabrik de Düsseldorf commercialisé sous la dénomination "Absorptionslackfarbe Nr 3494Schwarz", et celui commercialisé sous la dénomination "3621 Rampozink dunkelgrau" se sont avérés satisfaisants. Des parcloses en aluminium ou des profilés décoratifs en aluminium placés devant les parcloses en acier, ayant leur surface extérieure en aluminium anodisée en foncé, présentent aussi une capacité d'absorption de la chaleur suffisante.The two glazing beads 10, 11 are provided on their external faces with a layer 14 absorbing the heat radiation. As a heat-absorbing layer 14, it is possible to use, for example, a coating of an absorbent paint which has on the one hand an increased capacity for absorbing heat radiation and on the other hand an increased resistance to heat. also. Such a layer of paint, during a fire-resistance test, must retain its full absorption capacity at least for the first ten minutes after the start of the fire test. The product of Ernst B. Buchner Lackfabrik from Düsseldorf marketed under the name "Absorptionslackfarbe Nr 3494Schwarz", and that marketed under the name "3621 Rampozink dunkelgrau" have proved satisfactory. Aluminum glazing beads or decorative aluminum profiles placed in front of the steel glazing beads, having their outer surface in dark anodized aluminum, also have sufficient heat absorption capacity.

Dans la forme d'exécution de la fenêtre représentée sur la figure 5, le châssis de fenêtre est construit exactement comme celui de la figure 4, avec le chassis de base 9 et les parcloses 10, 11 qui sont pourvues sur leurs surfaces externes d'un revêtement 14 absorbant le rayonnement calorifique en "RAMPOZINK". La vitre simple est, dans ce cas, remplacée par un vitrage isolant doublé formé de deux feuilles 18 de verre, par exemple verre Float, ayant subi une trempe thermique. Le cadre intercalaire 19 du vitrage double prévu entre les feuilles de verre 18 est un profilé d'acier. Le vitrage isolant est rendu étanche par une couche de scellement 20 de la manière courante et est installé dans le chassis avec intercalation de couches d'amiante 12. Entre les feuilles de verre 18 et les parcloses 10, 11 est chaque fois disposée une bande d'étanchéité thermoconductrice 1. Cette construction de fenêtre atteint au cours d'un essais d'incendie, la classe de résistance au feu G 30.In the embodiment of the window shown in Figure 5, the window frame is constructed exactly like that of Figure 4, with the base frame 9 and the glazing beads 10, 11 which are provided on their external surfaces with a coating 14 absorbing the heat radiation in "RAMPOZINK". The single pane is, in this case, replaced by a doubled insulating glazing formed by two sheets 18 of glass, for example Float glass, having undergone thermal toughening. The intermediate frame 19 of the double glazing provided between the glass sheets 18 is a steel profile. The insulating glazing is sealed by a sealing layer 20 in the usual way and is installed in the frame with interleaving of asbestos layers 12. Between the sheets of glass 18 and the glazing beads 10, 11 is each time arranged a strip of thermoconductive sealing 1. This window construction attains, during a fire test, the fire resistance class G 30.

La figure 6 illustre une fenêtre apte à résister au feu, qui comporte un vitrage isolant formé de deux feuilles de verre 18 trempées thermiquement et qui est monté de manière asymétrique. Cette construction asymétrique assure que la fenêtre résiste à l'action d'un incendie du premier côté, c'est-à-dire celui du côté de la parclose 11, tandis que les feuilles de verre se briseraient sous l'action d'un feu venant de l'autre côté. De plus, le vitrage est serré dans le châssis de façon flexible d'une manière bien connue, du côté à ne pas soumettre au feu, de telle façon que des distorsions et des gauchissements des feuilles de verre sous l'effet de la chaleur n'entraînent pas forcément leur bris. Du côté éxposable à l'incendie, la parclose 11 en acier est pourvue d'un revêtement 14 en "RAMPOZINK" absorbant le rayonnement calorifique et entre la parclose 11 et le vitrage est intercalée une bande d'étanchéité thermoconductrice 1. De l'autre côté, à savoir celui à ne pas soumettre à l'incendie, la parclose 10 ne présente aucun revêtement absorbant la chaleur. Entre la parclose 10 et le vitrage est prévue une distance d'au moins environ 5 mm. Dans cet espace intermédiaire entre la parclose 10 et le vitrage sont disposées deux bandes d'étanchéité 22 en une matière incombustible, comme de l'amiante ou une autre matière du même genre et entre ces bandes d'étanchéité 22 se trouve une couche 23 en une matière expansible sous l'effet de la chaleur, par exemple du silicate de sodium. Lorsque la couche 23 s'expanse sous l'effet de la chaleur, elle assure par sa dilatation une étanchéité suffisante du chassis même aux endroits où, par un gauchiss- ment du cadre et/ou du vitrage la distance entre la parclose et le vitrage augmente. D'autre part, cette couche de matière expansible est suffisamment résistante à la chaleur et suffisamment flexible aux hautes températures pour éviter le transfert nuisible des forces de compression de la parclose au vitrage.FIG. 6 illustrates a window capable of withstanding fire, which comprises an insulating glazing formed by two sheets of glass 18 thermally toughened and which is mounted asymmetrically. This asymmetrical construction ensures that the window resists the action of a fire on the first side, that is to say that on the side of the glazing bead 11, while the glass sheets would break under the action of a fire coming from the other side. In addition, the glazing is clamped in the frame in a flexible manner in a well known manner, on the side not to be subjected to fire, in such a way that distortions and warping of the glass sheets under the effect of heat n 'do not necessarily cause their breakage. On the side exposed to fire, the steel glazing bead 11 is provided with a coating 14 in "RAMPOZINK" absorbing heat radiation and between the glazing bead 11 and the glazing is interposed a heat-conducting sealing strip 1. On the other on the side, namely the one not to be subjected to the fire, the glazing bead 10 has no heat absorbing coating. A distance of at least about 5 mm is provided between the glazing bead 10 and the glazing. In this intermediate space between the glazing bead 10 and the glazing are arranged two sealing strips 22 made of a non-combustible material, such as asbestos or a other material of the same kind and between these sealing strips 22 is a layer 23 of a material which is expandable under the effect of heat, for example sodium silicate. When the layer 23 expands under the effect of heat, by its expansion it ensures sufficient tightness of the frame even at the places where, by warping the frame and / or the glazing, the distance between the glazing bead and the glazing increases. On the other hand, this layer of expandable material is sufficiently resistant to heat and sufficiently flexible at high temperatures to avoid the harmful transfer of the compressive forces from the glazing bead to the glazing.

Dans la forme d'exécution représentée sur la figure 7, un chassis de construction symétrique est à nouveau prévu et est formé d'un profilé de chassis de base 9 et de deux parcloses 10, 11 dont les surfaces externes sont pourvues d'un revêtement 14 absorbant le rayonnement calorifique. Dans ce chassis, un vitrage est installé avec intercalation de chaque côté d'une bande d'étanchéité thermoconductrice . Ce vitrage comporte trois feuilles de verre 26, 27 et 28 en verre silicaté. Les deux feuilles de verre 26, 27 sont par exemple en verre Float trempé et sont reliées de manière étanche l'une à l'autre par un cadre intercalaire 29 et par une couche de scellement 30 et l'espace séparant les deux feuilles de verre est rempli d'une masse gélifiée 31 aqueuse et saline. Des double vitrages de ce genre remplis d'une masse gélifiée sont décrits, par exemple dans les demandes de brevets allemands publiés OS 27 13 849 et 30 37 015. Ce double vitrage rempli d'une masse gélifiée 31 est relié, par l'intermédiaire d'un autre intercalaire 32 et d'une autre couche de scellement 33, à l'autre feuille de verre silicate qui est par exemple en un verre Float trempé thermiquement. Cette feuille de verre 28 qui précède le double vitrage rempli d'un gel et qui en est espacée par un espace d'air, résiste, en cas d'incendie pendant au moins 30 minutes, sert d'écran thermique pour le double vitrage rempli du gel, de sorte que la chaleur n'agit sur ce vitrage avec gel qu'avec un retard considérable. Une fenêtre de cette construction satisfait aux exigences de la classe d'incendie F selon la norme DIN 4102 et on peut ainsi réaliser des fenêtres de la classe F 60 et F 90.In the embodiment shown in Figure 7, a symmetrical construction frame is again provided and is formed of a base frame profile 9 and two glazing beads 10, 11 whose outer surfaces are provided with a coating 14 absorbing heat radiation. In this frame, glazing is installed with interleaving on each side with a thermally conductive sealing strip. This glazing comprises three sheets of glass 26, 27 and 28 made of silicate glass. The two glass sheets 26, 27 are for example made of tempered float glass and are tightly connected to each other by an intermediate frame 29 and by a sealing layer 30 and the space separating the two glass sheets. is filled with an aqueous and saline gelled mass 31. Double glazing of this kind filled with a gelled mass is described, for example in the German patent applications published OS 27 13 849 and 30 37 015. This double glazing filled with a gelled mass 31 is connected, via from another interlayer 32 and from another sealing layer 33, to the other sheet of silicate glass which is for example made of thermally toughened Float glass. This glass sheet 28 which precedes the double glazing filled with a gel and which is spaced apart by an air space, withstands, in the event of a fire for at least 30 minutes, serves as a thermal screen for the double glazing filled gel, so that the heat acts on this glazing with gel only with a considerable delay. A window of this construction meets the requirements of fire class F according to DIN 4102, and windows of class F 60 and F 90 can thus be produced.
