Definitions
- the present invention relates to glazing resistant to fire comprising two panes hermetically assembled to their edges via a frame-shaped spacer, the interior space of this glazing being filled with a hydrogel containing a water-soluble salt.
- Fire resistant glazing of this technique is known for example from documents DE-2 713 849 C2, DE-3 530 968 C2, EP-0 001 531 B1 and 0 049 204 B1.
- the frame bracing is made of steel profiles resistant to corrosion, which are assembled by means of brackets also in corrosion resistant steel.
- the gel layer must be at least 15 mm thick to meet the requirements of the fire resistance class F 30.
- the thickness of the glazing will therefore be worth at least about 25 mm.
- glazing of the mentioned technique of a class of fire resistance determined, but with lower total thickness.
- such a requirement may be due to reasons of weight loss or because of determined frame structure which limits the thickness of the glazing.
- the invention aims to modify the structure of these known fire-resistant glazing in order to further increase the firewall effect.
- we must obtain an effect firewall as efficient as that offered by glazing known firebreaks with total glazing thickness lower.
- bracing frame between the two panes is made of heat resistant material, having a coefficient of thermal conductivity less than 2 kcal / mhK.
- the invention is based on the fact that during tests of fire resistance carried out on known glazing, destruction fire-resistant glazing generally begins at the edge. Obviously, water vaporizes faster near the metal spacer than the rest of the glass surface. However, on the side of the glazing away from the fire, the area located along the edge heats up faster than the area central and thus weakens faster than the center of the glass, which ultimately results in the destruction of the glazing from its marginal zone.
- the heating of the glazing in the marginal zone is greatly slowed down by the use spacers with a conductivity coefficient significantly lower than that of steel, and for a same thickness of the glazing unit, the resistance time fire will be significantly increased. In this way it is possible achieve with a significantly lower thickness of the unit glazing, the same fire resistance duration as known glazing.
- heat-resistant materials based on ceramic or silicate.
- Such materials have a coefficient of relatively low thermal conductivity, on the order of 0.5 to 1 kcal / mhK, while corrosion-resistant steel has a coefficient of thermal conductivity from 15 to 45 kcal / mhK.
- these materials have the particular advantage that they are insensitive to aggressive salt solution present in the intermediate space of the glazing, so that the addition of specific anticorrosive substances, proposed in document DE-3 530 968 C2 even in the event use of steel bracing frames resistant to corrosion is superfluous.
- silicate glass strips or profiles in particular usual float glass, have proven particularly suitable. If strips of silicate glass, it can in particular be stored without modifications to the usual sealing system with a internal butyl adhesive sealant, i.e. copolymer of isobutylene and isoprene, and a means sealing adhesive external in thiocol, i.e. a thermoplastic polymer from the group of alkyl polysulfides.
- a butyl adhesive sealant i.e. copolymer of isobutylene and isoprene
- a means sealing adhesive external in thiocol i.e. a thermoplastic polymer from the group of alkyl polysulfides.
- the adhesive system When using another ceramic material or silicate than the usual float glass, the adhesive system must, if necessary, be adapted to this material.
- Fire resistant glazing designed in accordance with the invention has, in addition to the favorable properties mentioned, the advantage that, thanks to thermal conduction lower in bracing, no measures particular for thermal insulation should only be taken at glazing frame level. This means for example that a relatively deeper mounting of the glazing in the frame, that is to say a significant overlap in the marginal zone glazing through the frame, is not necessary. Glazing fire resistant designed according to the invention can therefore be installed in construction frames clearly narrower, which gives the fire-resistant wall a lighter appearance.
- Fire protection glazing generally has like other glazings a rectangular shape, such so the bracing frame is made up of sections straight. However, it is obviously possible to manufacture fireproof glazing also in any other desired shape. So, for example, when the glass is used as material for the spacer, glass strips can be folded into any shape after heating to their bending temperature, and thus, by example, circular or semi-circular firebreak glazing can be made.
- the drawing is a vertical section view of a glazing fire barrier according to the invention.
- the glazing comprises two silicate glass panes 1, 2, each 5 mm thick and each in tempered float glass thermally.
- glass strips 3, 4, 5, 12 mm wide are used, for example in 4 mm thick float glass.
- These glass strips 3, 4, 5 are glued to the two panes 1, 2 via butyl adhesive layers 6, 7.
- the groove between the glass strips 3, 4, 5 and the areas along the edges glass 1, 2 is filled with a mass of material sealing tape 8 made of polysulfide. Space intermediate formed in this way between the two panes 1, 2 is filled with a salt hydrogel 9.
- bracing frame composed of glass strips 3, 4, 5
- corner pieces particular, as used in frames bracing made of sections of metal profiles do not are not necessary, since the different glass strips are joined together.
- a frame closed is first made from sections of sections and interlocking brackets and this framework as a whole is installed on one of the two panes
- the glass strips 3, 4, 5 are arranged separately one after the other on one of the two panes, after having been previously coated at least on one edge of an butyl adhesive layer. In this way, the frame of closed bracing is first assembled on the glass.
- the fire resistance test in accordance with DIN 4102, part 2, paragraphs 6.1 to 6.2.5 was made on glazing firewall designed this way.
- the test of resistance to fire was carried out on fire-resistant glazing in which the spacer, whose width was also 12 mm, was made of a corrosion-resistant steel profile, but the remaining structure of firebreak glazing was identical to fire-resistant glazing according to the invention. While the glazing fire barrier with steel bracing frame corrosion resistant fire resistant for 25 minutes, the fire-resistant glazing according to the invention has withstood the fire for 32 minutes and therefore conforms to the class of fire resistance F 30.

Abstract
Description
La présente invention concerne un vitrage résistant au feu comprenant deux vitres assemblées hermétiquement à leurs bords par l'intermédiaire d'une entretoise en forme de cadre, l'espace intérieur de ce vitrage étant rempli d'un hydrogel contenant un sel soluble dans l'eau.The present invention relates to glazing resistant to fire comprising two panes hermetically assembled to their edges via a frame-shaped spacer, the interior space of this glazing being filled with a hydrogel containing a water-soluble salt.
Des vitrages résistant au feu, de cette technique sont connus par exemple par les documents DE-2 713 849 C2, DE-3 530 968 C2, EP-0 001 531 B1 et 0 049 204 B1. Dans le cas de ces vitrages connus résistant au feu, le cadre d'entretoisement est fait de profilés en acier résistant à la corrosion, qui sont assemblés au moyen d'équerres d'emboítement également en acier résistant à la corrosion.Fire resistant glazing of this technique is known for example from documents DE-2 713 849 C2, DE-3 530 968 C2, EP-0 001 531 B1 and 0 049 204 B1. In the case of these known fire-resistant glazings, the frame bracing is made of steel profiles resistant to corrosion, which are assembled by means of brackets also in corrosion resistant steel.
L'effet de retardement du feu de tels vitrages en cas
d'incendie est basé sur le fait que tout d'abord, des
quantités considérables d'énergie provenant de la chaleur
dégagée sont absorbées par l'eau et vaporisent l'eau. Après la
vaporisation de l'eau, un écran thermique en mousse s'est
formé à partir du sel. Pendant la vaporisation de l'eau, la
température superficielle du vitrage, du côté opposé à
l'action de la chaleur, ne s'élève que de manière
insignifiante et reste inférieure à la valeur admissible de
140°K au-dessus de la température initiale suivant la norme
DIN 4102. Lorsqu'après la vaporisation de l'eau, l'écran
thermique en mousse s'est formé, celui-ci prend alors en
charge l'isolation thermique et empêche en particulier le
passage du rayonnement thermique à travers le vitrage. Suivant
l'épaisseur de la couche de gel, il est possible de fabriquer
de cette façon des vitrages coupe-feu, correspondant aux
classes de résistance au feu F 30, F 60 ou à des classes
supérieures suivant la norme DIN 4102, partie 2.The fire retardant effect of such glazing in the event
is based on the fact that, first of all,
considerable amounts of energy from heat
released are absorbed by water and vaporize water. After the
water spray, a foam heat shield has
formed from salt. During the spraying of water, the
glazing surface temperature, on the side opposite
the action of heat, only rises so
insignificant and remains below the admissible value of
140 ° K above the initial temperature according to the standard
DIN 4102. When after spraying water, the screen
thermal foam has formed, it then takes
loads the thermal insulation and prevents in particular the
passage of thermal radiation through the glazing. next
the thickness of the gel layer, it is possible to manufacture
in this way fire-resistant glazing, corresponding to
fire resistance classes F 30, F 60 or to classes
according to DIN 4102,
Dans le cas de vitrages résistant au feu de cette structure connue, suivant l'épaisseur et le type des vitres utilisées, la couche de gel doit être épaisse d'au moins 15 mm pour remplir les conditions de la classe de résistance au feu F 30. Lors de l'utilisation de deux vitres en verre trempé de 5 mm d'épaisseur chacune par exemple, l'épaisseur du vitrage vaudra de ce fait au moins environ 25 mm.In the case of fire-resistant glazing of this known structure, depending on the thickness and type of glass used, the gel layer must be at least 15 mm thick to meet the requirements of the fire resistance class F 30. When using two toughened glass panes of 5 mm thick each, for example, the thickness of the glazing will therefore be worth at least about 25 mm.
Dans de nombreux cas, il est intéressant d'utiliser des vitrages de la technique mentionnée, d'une classe de résistance au feu déterminée, mais présentant une moindre épaisseur totale. Par exemple, une telle exigence peut être due à des raisons de diminution de poids ou à cause d'une structure de cadre déterminée qui limite l'épaisseur du vitrage.In many cases it is interesting to use glazing of the mentioned technique, of a class of fire resistance determined, but with lower total thickness. For example, such a requirement may be due to reasons of weight loss or because of determined frame structure which limits the thickness of the glazing.
L'invention a pour but de modifier la structure de ces vitrages résistant au feu connus afin d'accroítre davantage l'effet pare-feu. En particulier, on doit obtenir un effet pare-feu aussi performant que celui offert par les vitrages coupe-feu connus avec une épaisseur totale du vitrage inférieure.The invention aims to modify the structure of these known fire-resistant glazing in order to further increase the firewall effect. In particular, we must obtain an effect firewall as efficient as that offered by glazing known firebreaks with total glazing thickness lower.
Ce but est atteint, conformément à l'invention, par le fait que le cadre d'entretoisement entre les deux vitres est fait d'un matériau résistant à la chaleur, présentant un coefficient de conductibilité thermique inférieur à 2 kcal/mhK.This object is achieved, in accordance with the invention, by the fact that the bracing frame between the two panes is made of heat resistant material, having a coefficient of thermal conductivity less than 2 kcal / mhK.
L'invention est basée sur le fait que lors d'essais de tenue au feu effectués sur les vitrages connus, la destruction du vitrage coupe-feu s'amorce en règle générale au bord. Evidemment, l'eau se vaporise plus vite à proximité de l'entretoise métallique que du reste de la surface de vitre. Cela étant, du côté du vitrage éloigné du feu, la zone située le long du bord s'échauffe plus rapidement que la zone centrale et, de la sorte, elle s'affaiblit plus rapidement que le centre de la vitre, ce qui aboutit finalement à la destruction du vitrage depuis sa zone marginale.The invention is based on the fact that during tests of fire resistance carried out on known glazing, destruction fire-resistant glazing generally begins at the edge. Obviously, water vaporizes faster near the metal spacer than the rest of the glass surface. However, on the side of the glazing away from the fire, the area located along the edge heats up faster than the area central and thus weakens faster than the center of the glass, which ultimately results in the destruction of the glazing from its marginal zone.
Conformément à l'invention, l'échauffement du vitrage dans la zone marginale est fortement ralenti par l'utilisation d'entretoises présentant un coefficient de conductibilité thermique nettement inférieur à celui de l'acier, et pour une même épaisseur de l'unité de vitrage, le temps de résistance au feu sera nettement accru. De cette façon, il est possible d'atteindre avec une épaisseur nettement inférieure de l'unité de vitrage, la même durée de résistance au feu que les vitrages connus.According to the invention, the heating of the glazing in the marginal zone is greatly slowed down by the use spacers with a conductivity coefficient significantly lower than that of steel, and for a same thickness of the glazing unit, the resistance time fire will be significantly increased. In this way it is possible achieve with a significantly lower thickness of the unit glazing, the same fire resistance duration as known glazing.
De préférence, pour l'entretoise, on utilise des matières résistant à la chaleur à base de céramique ou de silicate. De telles matières ont un coefficient de conductibilité thermique relativement bas, de l'ordre de 0,5 à 1 kcal/mhK, alors que l'acier résistant à la corrosion présente un coefficient de conductibilité thermique de 15 à 45 kcal/mhK. De plus, ces matières ont l'avantage particulier qu'elles sont insensibles à la solution salée agressive présente dans l'espace intermédiaire du vitrage, de sorte que l'addition de substances anticorrosives particulières, proposée dans le document DE-3 530 968 C2 même en cas d'utilisation de cadres d'entretoisement en acier résistant à la corrosion, est superflue.Preferably, for the spacer, we use heat-resistant materials based on ceramic or silicate. Such materials have a coefficient of relatively low thermal conductivity, on the order of 0.5 to 1 kcal / mhK, while corrosion-resistant steel has a coefficient of thermal conductivity from 15 to 45 kcal / mhK. In addition, these materials have the particular advantage that they are insensitive to aggressive salt solution present in the intermediate space of the glazing, so that the addition of specific anticorrosive substances, proposed in document DE-3 530 968 C2 even in the event use of steel bracing frames resistant to corrosion is superfluous.
A titre de matières pour les entretoises, des barres, des bandes ou des profilés en verre au silicate, en particulier en verre flotté habituel, se sont avérés particulièrement appropriés. En cas d'utilisation de bandes de verre au silicate, on peut notamment conserver sans modifications le système d'étanchéité habituel comportant un moyen d'étanchéité adhésif interne en butyle, c'est-à-dire un copolymère d'isobutylène et d'isoprène, et un moyen d'étanchéité adhésif externe en thiocol, c'est-à-dire un polymère thermoplastique du groupe des polysulfures d'alcoyle.As materials for spacers, bars, silicate glass strips or profiles, in particular usual float glass, have proven particularly suitable. If strips of silicate glass, it can in particular be stored without modifications to the usual sealing system with a internal butyl adhesive sealant, i.e. copolymer of isobutylene and isoprene, and a means sealing adhesive external in thiocol, i.e. a thermoplastic polymer from the group of alkyl polysulfides.
Il est avantageux d'améliorer l'adhérence entre le gel et les entretoises en appliquant sur celles-ci un promoteur d'adhérence. Dans le cas du verre silico-sodo-calcique habituel, les primaires décrits notamment dans le brevet EP-B-0 001 531 conviennent. Dans ce document, on préconise l'utilisation de promoteurs d'adhérence à base de silane susceptible de réagir avec les doubles ou triples liaisons carbonées de l'hydrogel ou à base de titanates ou de zirconates organiques.It is advantageous to improve the adhesion between the gel and the spacers by applying a promoter to them adhesion. In the case of soda-lime-silica glass usual, the primaries described in particular in patent EP-B-0 001 531 are suitable. In this document, we recommend the use of silane adhesion promoters likely to react with double or triple bonds carbonaceous hydrogel or based on titanates or organic zirconates.
En cas d'utilisation d'une autre matière céramique ou silicatée que le verre flotté habituel, le système adhésif doit, le cas échéant, être adapté à cette matière.When using another ceramic material or silicate than the usual float glass, the adhesive system must, if necessary, be adapted to this material.
Un vitrage résistant au feu conçu conformément à l'invention présente, outre les propriétés favorables mentionnées, l'avantage que, grâce à la conduction thermique plus faible dans le cadre d'entretoisement, aucune mesure particulière pour l'isolation thermique ne doit être prise au niveau du châssis du vitrage. Ceci signifie par exemple qu'un montage relativement plus profond du vitrage dans le châssis, c'est-à-dire un recouvrement important dans la zone marginale du vitrage par le châssis, n'est pas nécessaire. Des vitrages résistant au feu conçus conformément à l'invention peuvent donc être installés dans des châssis de construction nettement plus étroite, ce qui confère à la paroi résistant au feu un aspect plus léger.Fire resistant glazing designed in accordance with the invention has, in addition to the favorable properties mentioned, the advantage that, thanks to thermal conduction lower in bracing, no measures particular for thermal insulation should only be taken at glazing frame level. This means for example that a relatively deeper mounting of the glazing in the frame, that is to say a significant overlap in the marginal zone glazing through the frame, is not necessary. Glazing fire resistant designed according to the invention can therefore be installed in construction frames clearly narrower, which gives the fire-resistant wall a lighter appearance.
En règle générale, les vitrages coupe-feu présentent comme d'autres vitrages une forme rectangulaire, de telle sorte que le cadre d'entretoisement se compose de sections droites. Toutefois, il est évidemment possible de fabriquer des vitrages coupe-feu également dans n'importe quelle autre forme souhaitée. Ainsi, par exemple, lorsque le verre est utilisé comme matériau pour l'entretoise, les bandes de verre peuvent être pliées dans n'importe quelle forme souhaitée après chauffage à leur température de cintrage, et ainsi, par exemple, des vitrages coupe-feu circulaires ou semi-circulaires peuvent être fabriqués.Fire protection glazing generally has like other glazings a rectangular shape, such so the bracing frame is made up of sections straight. However, it is obviously possible to manufacture fireproof glazing also in any other desired shape. So, for example, when the glass is used as material for the spacer, glass strips can be folded into any shape after heating to their bending temperature, and thus, by example, circular or semi-circular firebreak glazing can be made.
D'autres particularités et avantages de l'invention ressortiront des revendications et de la description suivante d'un exemple de réalisation préféré donné avec référence au dessin.Other features and advantages of the invention will emerge from the claims and the following description of a preferred embodiment given with reference to drawing.
Le dessin est une vue en coupe verticale d'un vitrage coupe-feu conforme à l'invention.The drawing is a vertical section view of a glazing fire barrier according to the invention.
Le vitrage comprend deux vitres en verre au silicate 1,
2, épaisses chacune de 5 mm et chacune en verre flotté trempé
thermiquement. A titre d'entretoise, entre ces deux vitres 1,
2, on utilise des bandes de verre 3, 4, 5, larges de 12 mm,
par exemple en verre flotté épais de 4 mm. Ces bandes de verre
3, 4, 5 sont collées aux deux vitres 1, 2 par l'intermédiaire
de couches adhésives 6, 7 de butyle. La rainure entre les
bandes de verre 3, 4, 5 et les zones situées le long des bords
des vitres 1, 2 est remplie d'une masse de matière
d'étanchéité adhésive 8 faite de polysulfure. L'espace
intermédiaire formé de cette façon entre les deux vitres 1, 2
est rempli d'un hydrogel salin 9. The glazing comprises two
Dans le cas de la fabrication du vitrage coupe-feu, pour
pouvoir remplir de liquide gélifiant l'espace intermédiaire
dans le double vitrage préparé, on ménage un trou 10 dans la
bande de verre 5, à proximité de son extrémité inférieure, ou
on en coupe un coin. De même, on ménage dans la bande de verre
opposée, qui n'est pas visible sur la vue en coupe, à
proximité de son extrémité supérieure un trou qui sert à titre
d'orifice de mise à l'atmosphère. Evidemment, ces trous qui
dans un premier temps doivent être maintenus libres de manière
appropriée, par l'introduction par exemple de courtes sections
de tube dans les trous, sont obturés de manière étanche après
la polymérisation du gélifiant et après l'enlèvement des
sections de tube utilisées pour le remplissage et la mise à
l'atmosphère, par la mise en place de la matière d'étanchéité
adhésive.In the case of the manufacture of fire-resistant glazing, for
ability to fill gelling liquid with intermediate space
in the prepared double glazing, there is a
Dans le cas de l'agencement du cadre d'entretoisement
composé des bandes de verre 3, 4, 5, des pièces d'angle
particulières, telles qu'elles sont utilisées dans les cadres
d'entretoisement faits de sections de profilés métalliques, ne
sont pas nécessaires, puisque les différentes bandes de verre
sont assemblées l'une à l'autre. Alors que dans le procédé
habituel, utilisant des entretoises métalliques, un cadre
fermé est d'abord fabriqué à partir de sections de profilés et
d'équerres d'emboítement et ce cadre dans sa globalité est
posé sur une des deux vitres, dans le cas du vitrage coupe-feu
conforme à l'invention, les bandes de verre 3, 4, 5 sont
disposées séparément l'une après l'autre sur une des deux
vitres, après avoir été préalablement enduites au moins sur un
bord d'une couche adhésive de butyle. De cette façon, le cadre
d'entretoisement fermé est d'abord assemblé sur la vitre.In the case of the arrangement of the bracing frame
composed of
L'essai de tenue au feu conforme à la norme DIN 4102,
partie 2, paragraphes 6.1 à 6.2.5 a été réalisé sur un vitrage
coupe-feu conçu de cette façon. De même, l'essai de tenue au
feu a été réalisé sur un vitrage coupe-feu dans lequel
l'entretoise, dont la largeur valait également 12 mm, était
faite d'un profilé en acier résistant à la corrosion, mais la
structure restante du vitrage coupe-feu était identique au
vitrage coupe-feu conforme à l'invention. Alors que le vitrage
coupe-feu comportant le cadre d'entretoisement en acier
résistant à la corrosion résistait au feu pendant 25 minutes,
le vitrage coupe-feu conforme à l'invention a résisté au feu
pendant 32 minutes et est donc conforme à la classe de
résistance au feu F 30.The fire resistance test in accordance with DIN 4102,
