Description
La présente invention se rapporte à un verre composite qui comprend une couche de verre et une couche d'une autre matière reliée à celle-ci. The present invention relates to a composite glass which comprises a layer of glass and a layer of another material connected thereto.
On connaît des verres composites composés de plusieurs couches. Il est également connu, pour obtenir un verre ne produisant pas d'éclats, d'accoler le verre directement à une plaque de matière plastique cohérente. Dans ces conditions, lorsque le verre se brise, ses éclats restent colles à la matière plastique. Toutefois, un inconvénient de-ces sortes de verres réside dans leur faible pouvoir d'isolation thermique ainsi que dans le fait que lorsque les couches de matière plastique utilisées sont trop minces, il peut arriver, sous l'action de coups ou de chocs relativement violents, qu'il se produise une déchirure dans la couche de matière plastique cohérentes à la suite de quoi, sinon de petits éclats, mais néanmoins des morceaux relativement grands ou bien des bords tranchants peuvent se former. Composite glasses are known which consist of several layers. It is also known, in order to obtain a glass which does not produce splinters, to attach the glass directly to a plate of coherent plastic material. Under these conditions, when the glass breaks, its shards remain stuck to the plastic. However, a disadvantage of these kinds of glasses lies in their low thermal insulation power as well as in the fact that when the plastic layers used are too thin, it can happen, under the action of relatively knocks or shocks. violent, that a tear in the layer of coherent plastic material occurs as a result of which, if not small fragments, but nevertheless relatively large pieces or sharp edges may form.
La présente invention permet d'éviter ces inconvénients en utilisant une plaque cloisonnée composée de deux plaques de couverture reliées par des barrettes ou des cloisons, de préférence en une matière plastique appropriée, qui est reliée à la plaque de verre, l'une des deux plaques de couverture de cette plaque cloisonnée s'appliquant tout entière ou partiellement contre le verre et étant, le cas échéant, collée à celui-ci, cependant que la région des bords est étanchée, le cas échéant. The present invention makes it possible to avoid these drawbacks by using a partitioned plate composed of two cover plates connected by bars or partitions, preferably made of a suitable plastic material, which is connected to the glass plate, one of the two cover plates of this partitioned plate applying entirely or partially against the glass and being, if necessary, bonded thereto, while the region of the edges is sealed, if necessary.
La plaque cloisonnée peut, avantageusement, être en une matière plastique appropriée, et peut comporter deux plaques de couverture espacées. Entre ces plaques de couverture s'étendent des barrettes ou des cloisons parallèles entre lesquelles sont ménagés des intervalles vides. Ainsi, les déchirures qui pourraient se former à travers la plaque de couverture voisine du verre sont interrompues par les canaux d'air séparant les cloisons, de sorte que même si la première plaque de couverture venait à se déchirer, la seconde resterait intacte. Ainsi, même en utilisant des matières relativement minces, on obtient une plus grande sécurité. On peut, en même temps, obtenir un verre composite qui, tout en étant plus léger, a une plus grande solidité et résistance à la rupture.Par suite de la présence des canaux d'air entre les plaques de couverture, l'isolation thermique est sensiblement meilleure que celle qu'on obtient avec des plaques pleines. Du fait que l'on utilise moins de matière plastique, il devient possible de produire un verre composite plus solide, comparativement à un verre composite traditionnel de même poids.The partitioned plate may advantageously be made of a suitable plastic material, and may comprise two spaced cover plates. Between these cover plates extend parallel strips or partitions between which are provided empty gaps. Thus, the tears which could form through the cover plate adjacent to the glass are interrupted by the air channels separating the partitions, so that even if the first cover plate were to tear, the second would remain intact. Thus, even when using relatively thin materials, greater security is obtained. We can, at the same time, obtain a composite glass which, while being lighter, has greater strength and resistance to breakage. As a result of the presence of air channels between the cover plates, thermal insulation is significantly better than that obtained with solid plates. Because less plastic is used, it becomes possible to produce a more solid composite glass, compared to a traditional composite glass of the same weight.
En particulier, du fait que l'une. des plaques de couverture de la plaque cloisonnée s'applique directement contre le verre et est collée à celui-ci, le risque que des éclats puissent se détacher est consåderablement réduit. Dans ces conditions, il devient possible de produire a meilleur marché des verres composites, en particulier, pour la construction de serres et pour des applications analogues, qui présentent une grande sécurité contre la grêle. De plus, même dans le cas où la grêle arriverait à briser le verre, il n'en résulterait que des dégâts limités. En outre, les éclats de verre sont empêches de tomber à l'intérieur de la serre et de souiller le sol de celle-ci, ce qui aurait obligé de nettoyer complètement les plantations.A cela s'ajoute que ctest précisément dans le cas des serres qu'une bonne isolation thermique a une importance primordiale.In particular, the fact that one. cover plates of the partitioned plate is applied directly against the glass and is glued to it, the risk that fragments may come off is considerably reduced. Under these conditions, it becomes possible to produce at a lower cost composite glasses, in particular, for the construction of greenhouses and for similar applications, which offer great security against hail. In addition, even if the hail breaks the glass, only limited damage will result. In addition, shards of glass are prevented from falling inside the greenhouse and contaminating the soil, which would have obliged to completely clean the plantations. In addition, this is precisely in the case of greenhouses that good thermal insulation is of paramount importance.
En outre, du fait que les serres exigent de grandes surfaces vitrées, il est clair que l'économie ainsi réalisée joue un rôle essentiel. Il est avantageux que la plaque cloisonnée soit faite d'une matière plastique relativement rigide. Pour la construc tio de serres, il est également avantageux que les plaques cloisonnées soient en une matière transparente. Dans cette dernière application, il convient d'ajouter que les cloisons et les canaux d'air compris entre celles-ci ont pour effet de dévier et de diffracter les rayons solaires, produisant ainsi une distribution diffuse de ces rayons, qui est extrêmement souhaitable.In addition, since greenhouses require large glazed areas, it is clear that the savings thus made play an essential role. It is advantageous if the partitioned plate is made of a relatively rigid plastic. For the construction of greenhouses, it is also advantageous if the partitioned plates are made of a transparent material. In the latter application, it should be added that the partitions and the air channels included between them have the effect of deflecting and diffracting the sun's rays, thereby producing a diffuse distribution of these rays, which is extremely desirable.
Les plaques cloisonnées peuvent-être en un polycarbonate. The partitioned plates may be made of polycarbonate.
loutefois, d'autres matières plastiques sont également utilisables à cette fin, par exemple, le plexiglas, le polychlorure de vinyle, le polyéthylène, ainsi que d'autres matières plastiques analogues. However, other plastics can also be used for this purpose, for example, plexiglass, polyvinyl chloride, polyethylene, and other similar plastics.
Il n'est égalenent pas indispensable que les plaques cloisonnées s'appliquent complètement contre le verre. En effet, il est parfaitement possible de relier la plaque cloisonnée, par exemple, par l'intermédiaire de barrettes marginales, d 'é- liements d'espaze:rnt ou autres, au verre, en ménageant un intervalle entre eux.On pourrait également monter la plaque de verre et la plaque cloisonnée dans un cadre, à la manière des vitrages isolants connus, ce qui permet d'obtenir une isolation thermique renforcée, comparativement à ces derniers, grâce à la présence, d'une part, d'un~intervalle drairentre le verre et la plaque cloisonnée, et d'autre part, des canaux de la plaque cloisonnée, ce résultant étant obtenu en conservant l'avantage de la diffusion de la lumière, tout en augmentant la sécurité contre les fractures, en particulier en utilisant pour la face extérieure des matières plastiques tenaces, ne produisant pas d'éclats ou bien en évitant, par la présence de la surface de matière plastique du côté intérieur dans tous les cas où des éclats de verre pourraient tomber à l'intérieur du local, puisque ces éclats de verre sont arrêtés par la surface cohérente de matière plastique. La résistance totale et la rigidité de ce verre composite est considérablement augmentée par la ténacité des plaques cloisonnées et par la solidité du verre, comparativement aux plaques cloisonnées seules et aux vitrages isolants entièrement en verre. It is not also essential that the partitioned plates be applied completely against the glass. In fact, it is perfectly possible to connect the partitioned plate, for example, by means of marginal bars, spanish elements: rnt or others, to the glass, leaving a gap between them. mount the glass plate and the partitioned plate in a frame, in the manner of known insulating glazing, which makes it possible to obtain reinforced thermal insulation, compared with the latter, thanks to the presence, on the one hand, of a ~ interval drairentre the glass and the partitioned plate, and on the other hand, channels of the partitioned plate, this resulting being obtained while preserving the advantage of the diffusion of the light, while increasing the safety against fractures, in particular by using stubborn plastics which do not produce splinters for the outer face or by avoiding, by the presence of the plastics surface on the inner side in all cases where shards of glass could fall inside the lo cal, since these shards of glass are stopped by the coherent surface of plastic. The total strength and rigidity of this composite glass is considerably increased by the toughness of the partitioned plates and by the solidity of the glass, compared to partitioned plates alone and insulating glazing entirely made of glass.
Il est également possible de monter la plaque de verre et la plaque cloisonnée dans un cadre, en ménageant une certaine distance entre elles. It is also possible to mount the glass plate and the partitioned plate in a frame, leaving a certain distance between them.
Pour étancher les plaques cloisonnées ou les canaux de ces plaques et la liaison entre le verre et la plaque cloisonnée, l'invention préconise d'utiliser pour assurer l'étanché- ité de la région marginale de l'ensemble, un caoutchouc de silicone ou un autre mastic approprié. La vitre peut être collée à la plaque cloisonnée soit complètement, soit par des points ou des filets d'adhésif. Un adhésif particulièrement avantageux est une colle de silicone, mais on pourrait également utiliser d'autres adhésifs assurant une bonne solidarisation. To seal the partitioned plates or the channels of these plates and the connection between the glass and the partitioned plate, the invention recommends the use, to ensure the tightness of the marginal region of the assembly, of a silicone rubber or another suitable sealant. The glass can be glued to the partitioned plate either completely, or by dots or strips of adhesive. A particularly advantageous adhesive is a silicone glue, but one could also use other adhesives ensuring good bonding.
D'autres caractéristiques et avantages de l'invention ressortiront de la descrIption qui va suivre, qui n'a, bien entendu, aucun caractère limitatif, en réference aux dessins annexés sur lesquels
La figure I est une vue latérale, partiellement en coupe, d'un verre composite conforme à l'invention
La figure 2 est une vue en plan à échelle réduite d'une telle plaque ; et,
La figure 3 est une vue latérale, partiellement en coupe, d'une variante de réalisation de l'invention.Other characteristics and advantages of the invention will emerge from the description which follows, which, of course, has no limiting character, with reference to the accompanying drawings in which
Figure I is a side view, partially in section, of a composite glass according to the invention
Figure 2 is a plan view on a reduced scale of such a plate; and,
Figure 3 is a side view, partially in section, of an alternative embodiment of the invention.
Dans les exemples de réalisation représentés, la plaque cloisonnée 1 se compose d'une première plaque de couverture 2, et d'une seconde plaque de couverture 3, ces deux plaques étant reliées par des cloisons. Entre les cloisons et les deux plaques 2, 3 sont formés des canaux 8 qui sont remplis d'air. L'ensemble comprendégalement des plaques ce verre 5. Dans l'exemple de réalisation représenté sur les figures 1 et 2, la plaque cloisonnée 1 est directement reliée à la plaque de verre 5, la solidarisation étant assurée par des filets d'adhésif 7, mais pourrait également être réalisée par une couche adhésive continue. La plaque cloisonnée 1 est un peu plus petite que la plaque de verre 5 et un bourrelet de mastic de silicone 6 assure l'é- tanchéité des canaux 8 et la liaison entre la plaque cloisonnée et le verre. In the exemplary embodiments shown, the partitioned plate 1 is composed of a first cover plate 2, and of a second cover plate 3, these two plates being connected by partitions. Between the partitions and the two plates 2, 3 are formed channels 8 which are filled with air. The assembly also includes plates of this glass 5. In the embodiment shown in FIGS. 1 and 2, the partitioned plate 1 is directly connected to the glass plate 5, the connection being ensured by adhesive threads 7, but could also be achieved by a continuous adhesive layer. The partitioned plate 1 is slightly smaller than the glass plate 5 and a bead of silicone sealant 6 seals the channels 8 and the connection between the partitioned plate and the glass.
Dans l'exemple de réalisation de la figure 3, la plaque de verre 5 et la plaque cloisonnée 1 sont séparées par des éléments d'espacement 12 et sont montés dans un cadre 9, des bandes d'étanchéité 10 étant prévues le long des bords, entre la plaque cloisonnée 1 et la plaque de verre 5, d'autres bandes d'étanchéité 11 étant interFosées entre le cadre 9 et la plaque cloisonnée 1. In the embodiment of Figure 3, the glass plate 5 and the partitioned plate 1 are separated by spacers 12 and are mounted in a frame 9, sealing strips 10 being provided along the edges , between the partitioned plate 1 and the glass plate 5, other sealing strips 11 being interFosed between the frame 9 and the partitioned plate 1.
Dans les exemples de réalisation ci-dessus, la plaque cloisonnée est constituée par un polycarbonate transparent et rigide. Toutefois, il est bien évident que de nombreuses variantes de réalisation sont possibles. C'est ainsi, par exemple, qu'on pourrait utiliser, à la place des éléments d'espacement 12, des barrettes d'espacement (dans l'exemple de la figure 3). In the exemplary embodiments above, the partitioned plate consists of a transparent and rigid polycarbonate. However, it is obvious that many alternative embodiments are possible. Thus, for example, one could use, instead of spacers 12, spacers (in the example of Figure 3).
Des éléments d'espacement croix pourraient également être utilisés. Les cadres utilisés pourraient être en fer, mais également en une matière plastique appropriée. Il est également possible de supprimer le cadre, en ne prévoyant que les bandes d'étanchéité. Dans le mode de réalisation de la figure 1, le collage pourrait s'effectuer sur toute la surface. Il est toutefois également possible de ne prévoir qu'un collage par points.Cross spacers could also be used. The frames used could be made of iron, but also of a suitable plastic material. It is also possible to remove the frame, providing only the sealing strips. In the embodiment of Figure 1, the bonding could be done over the entire surface. However, it is also possible to provide only point bonding.
La matière des cloisons peut avantageusement être rigide, mais il est également possible d'utiliser une matière déformable, souple ou élastique. Les plaques cloisonnées peuvent être en couleur ou opaques.The material of the partitions can advantageously be rigid, but it is also possible to use a deformable, flexible or elastic material. The partitioned plates can be colored or opaque.
Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détails sans sortir pour cela du cadre de l'invention. Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of details can be made without departing from the scope of the invention.
