Abstract

The insulating glazing panel comprises inner (2) and outer (1) walls positioned on either side of an intermediate support (5) which contains a vacuum. The outer wall is thick and rigid whilst the inner wall is relatively thin and flexible. The inner and outer walls are held in place on the support by atmospheric pressure acting on their surfaces. The inner and outer walls are made of glass. The panel may be used as a double-glazing window, or as a solar collector.

Description

La présente invention concerne un panneau à double paroi, et plus particulièrement un panneau isolant dans lequel le vide est créé à l'intérieur de l'espace délimité par les deux parois pour éviter les déperditions thermiques. The present invention relates to a double-walled panel, and more particularly to an insulating panel in which the vacuum is created inside the space delimited by the two walls to avoid heat loss.

On conçoit que dans un tel panneau, les deux parois sont soumises à des efforts importants, dûs à ce que chaque panneau possède une face soumise a' la pression ~atmosphérique et une face soumise à une pression nulle ou très réduite. Si les parois sont réalisées en matériaux fragiles, tels que le verre utilisé pour la réalisation de vitra#ges isolants dans la construction de bâtiments, ou de vitrages sous vide dans la fabrication de capteurs solaires'- plans, il existe un risque sérieux de rupture des matériaux utilisés, en raison de ce que ces matériaux ne peuvent se déformer de façon #importante sans se casser, saus l'effet des forces auxquelles ils sont soumis. It is understood that in such a panel, the two walls are subjected to significant forces, due to the fact that each panel has a face subjected to atmospheric pressure and a face subjected to zero or very reduced pressure. If the walls are made of fragile materials, such as glass used for the production of insulating glass in the construction of buildings, or vacuum glazing in the manufacture of solar collectors, there is a serious risk of rupture. of the materials used, due to the fact that these materials cannot deform significantly # without breaking, due to the effect of the forces to which they are subjected.

Un réduction symétrique de l'épaisseur des deux parois les rendrait évidemment davantage déformables, mais elle ne pourrait que diminuer la résistance mécanique de l'-ensemble du panneau, et ne constiturait.donc pas une solution valable. A symmetrical reduction in the thickness of the two walls would obviously make them more deformable, but it could only reduce the mechanical resistance of the entire panel, and would therefore not constitute a valid solution.

La présente invention remédie a ces inconvénients, en fournissant un panneau à double paroi comprenant une première paroi relativement épaisse et rigide appliquée sur un cté d'une structure intercalaire ajourée, et une seconde paroi relativement mince et déformable appliguée sur l'autre coté de la structure intercalaire ajouree. The present invention overcomes these drawbacks by providing a double-walled panel comprising a first relatively thick and rigid wall applied to one side of an openwork intermediate structure, and a second relatively thin and deformable wall applied to the other side of the openwork interlayer structure.

La paroi de plus faible épaisseur peut, sans risque de se briser, subir.des déformations qui ne sont pas transmises à la paroi la plus épaisse, laquelle par 11 intermédiaire de la structure intercalaire est "por- teuse" de la paroi la plus mince. On élimine ainsi sensihlement le risque de casse, notamment dans le cas de proisenb=rtout en permettant des géfommat ons élastiques capables, notamment, d'absorber des irrégularités dimen sionnelles de la structure intercalaire. The thinner wall can, without risk of breaking, undergo deformations which are not transmitted to the thicker wall, which via the intermediate structure is "bearing" the thinner wall . This eliminates sensihlement the risk of breakage, especially in the case of proisenb = rtout by allowing elastic géfommat ons capable, in particular, of absorbing dimensional irregularities of the interlayer structure.

La paroi épaisse et la paroi mince peuvent être assemblées matériellement de part et d'autre de la structure intercalaire. Toutefois, dans le cas où le vide est créé entre ces deux parois, il sera avantageux de-réaliser la réunion des composants du panneau en mettant simplement à profit la pression de l'air extérieure, en application de l'effet physique dit de "Magdebourg qui plaquera nécessairement la paroi épaisse du panneau, comme sa paroi-mince, contre les côtés correspondants de la structure intercalaire, les efforts élevés résultant de cet assemblage mécanique étant parfaitement absorbés grâce au principe de l'invention consistant à utiliser deux parois d'épaisseurs très différentes. The thick wall and the thin wall can be physically assembled on either side of the intermediate structure. However, in the case where a vacuum is created between these two walls, it will be advantageous to unite the components of the panel by simply taking advantage of the pressure of the outside air, in application of the physical effect known as " Magdeburg which will necessarily tackle the thick wall of the panel, like its thin wall, against the corresponding sides of the intermediate structure, the high forces resulting from this mechanical assembly being perfectly absorbed thanks to the principle of the invention consisting in using two walls of very different thicknesses.

L'invention permet non seulement la réalisation de panneaux isolants de forme plane, pour vitrages et capteurs solaires, mais également la réalisation simple de panneaux cintrés : en partant de deux parois appliquées par l'effet du vide de part et d'autre d'une structure intercalaire, on courbe l'ensemble qui conserve alors la forme obtenue grâce à la friction des parois sur les deux faces de la structure intercalaire. Le principe des deux parois d'épaisseurs inégales garantit la solidité de l'ensemble pendant et après l'opération de cintrage. The invention allows not only the production of insulating panels of planar shape, for glazing and solar collectors, but also the simple production of curved panels: starting from two walls applied by the effect of the vacuum on either side of an intermediate structure, the assembly is curved which then retains the shape obtained by the friction of the walls on the two faces of the intermediate structure. The principle of two walls of uneven thickness guarantees the solidity of the assembly during and after the bending operation.

Cette application concerne notamment la réalisation de serres pour les cultures.This application relates in particular to the production of greenhouses for crops.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exem ple non limitatif, une forme d'exécution de ce panneau à double paroi, et en illustrant une application particulière
Figure 1 est une vue en coupe transversale d'un panneau conforme à la présente invention, de forme plane;
Figure 2 représente, toujours en coupe, un panneau selon l'invention cintré, pouvant constituer une serre.In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this double-walled panel, and by illustrating a particular application
Figure 1 is a cross-sectional view of a panel according to the present invention, of planar shape;
Figure 2 shows, still in section, a panel according to the curved invention, which may constitute a greenhouse.

Le panneau représenté au dessin comprend une première paroi 1 en verre rigide car d'épaisseur relativement importante indiquée E, et une seconde paroi 2 en verre, sensiblemen-t parallèle à la première,qui est déformable car d'épaisseur relativement faible indiquée e. Dans l'espace 3 délimité par les deux parois 1 et 2 et par un joint périphérique 4 (figure 1) est créé le vide. The panel shown in the drawing comprises a first wall 1 made of rigid glass because of relatively large thickness indicated E, and a second wall 2 of glass, sensiblemen-t parallel to the first, which is deformable because of relatively small thickness indicated e. In the space 3 delimited by the two walls 1 and 2 and by a peripheral seal 4 (Figure 1) is created the vacuum.

L'espace 3 revoit également une structure intercalaire appropriée 5, telle qu'une structure isolante en "nid d'abeilles"' à cellules communicantes. Les deux parois en verre 1 et 2 sont appliquées de part et d'autre de la structure intercalaire 5 par l'effet de la pression de l'air extérieus P, utilisée comme seul moyen d'assemblage des constituants du panneau, y compris le joint 4.The space 3 also sees an appropriate intermediate structure 5, such as an insulating "honeycomb" structure with communicating cells. The two glass walls 1 and 2 are applied on either side of the intermediate structure 5 by the effect of the pressure of the external air P, used as the only means of assembling the components of the panel, including the attached 4.

Toutes les déformations dues à la pression de l'air
P et aux éventuelles irrégularités de planéité et d'épaisseur de la structure intercalaire 5 sont absorbées par la seule paroi 2 de faible épaisseur e, qui présente une souplesse suffisante pour subir ces déformations sans risque de se briser. La paroi 1 de forte épaisseur E constitue la partie "porteuse" du panneau.All deformations due to air pressure
P and any irregularities in flatness and thickness of the intermediate structure 5 are absorbed by the single wall 2 of thin thickness e, which has sufficient flexibility to undergo these deformations without risk of breaking. The wall 1 of great thickness E constitutes the "load-bearing" part of the panel.

La figure 1 représente un panneau à double paroi 1, 2 selon l'invention de forme plane, pouvant constituer un double vitrage isolant utilisable dans la constructionde b#timents, ou encore un double vitrage sous vide utilisable dans la fabrication de capteurs solaires plans. 1 shows a double wall panel 1, 2 according to the invention of planar shape, which can constitute a double insulating glazing usable in the construction of buildings, or even a double glazing under vacuum usable in the manufacture of flat solar collectors.

Dans ce genre d'applications, le panneau sera maintenu sur un cadre ou un châssis par le bord de sa paroi 1 la plus épaisse,placée du côté extérieur.In this type of application, the panel will be held on a frame or a chassis by the edge of its thickest wall 1, placed on the outside.

Un panneau réalisé selon le principe de la figure 1, donc initialement plan, peut aussi âtre cintré comme l'illustre la figure 2, et monté-sur le sol 6, pour constituer une serre de culture, laquelle se maintient dans sa forme cintrée simplement par la friction des parois en verre 1 et 2 sur la structure intercalaire 5, sous l'effet de la pression de l'air extérieure P. A panel produced according to the principle of FIG. 1, therefore initially planar, can also be curved as illustrated in FIG. 2, and mounted on the ground 6, to constitute a greenhouse for cultivation, which is maintained in its curved form simply by the friction of the glass walls 1 and 2 on the intermediate structure 5, under the effect of the pressure of the outside air P.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce panneau à double paroi qui a été décrite ci-dessus, à titre'd'exemple ; elle enembrasse, au contraire, toutes les variantes de réalisation et d'application fondées sur le même principe. C'est ainsi, notamment, que l'on ne s'éloignerait pas du cadre de l'invention par l'utilisation d'autres matériaux, transparents ou non, pour la réalisation des deux parois 1 et 2 d'épaisseurs inégales E et e, en employant éventuellement des matériaux distincts pour les deux parois de manière à obtenir les caractéristiques mécaniques voulues non seulement par le choix de l'épaisseur des matériaux mais aussi en fonction de la nature de ces matériaux.  It goes without saying that the invention is not limited to the sole embodiment of this double-wall panel which has been described above, by way of example; on the contrary, it embraces all variants of implementation and application based on the same principle. Thus, in particular, that one would not depart from the scope of the invention by the use of other materials, transparent or not, for the production of the two walls 1 and 2 of unequal thickness E and e, possibly using separate materials for the two walls so as to obtain the desired mechanical characteristics not only by the choice of the thickness of the materials but also as a function of the nature of these materials.
