Description
La présente invention se rapporte à un joint réalisant ltétanchéité entre deux parois, notamment deux parois planes parallèles, qui délimitent une enceinte sous vide. The present invention relates to a seal providing a seal between two walls, in particular two parallel flat walls, which delimit a vacuum enclosure.
Pour la réalisation de l'étanchéité et de l'assemblage entre deux parois en verre, l'on utilise déjà des procédés de jonction par soudure de verre à bas point de fusion. For the sealing and the assembly between two glass walls, use is already made of joining processes by welding glass with a low melting point.
Ces procédés conduisent à des ruptures, en raison des dilatations différencielles des deux parois, dues aux écarts de température entre une paroi "intérieure" et une paroi "extérieure" par exemple. Il est aussi connu d'utiliser des barreaux en verre, collés par des joints étanches pour réunir deux parois en verre ; on accepte ainsi certaines déformations, mais au détriment de l'étanchéité.These processes lead to ruptures, due to the differential expansions of the two walls, due to the temperature differences between an "interior" wall and an "exterior" wall for example. It is also known to use glass bars, glued by tight seals to join two glass walls; some deformations are thus accepted, but to the detriment of the seal.
La présente invention remédie à ces inconvénients, en fournissant un joint spécialement adapté aux enceintes sous vide, qui peut se déformer sans risques de rupture de son contact étanche avec les deux parois, et qui réalise l'assemblage de ces parois par l'effet du vide lui-meme. The present invention overcomes these drawbacks by providing a seal specially adapted to vacuum chambers, which can deform without risk of breaking its tight contact with the two walls, and which assembles these walls by the effect of empty itself.
Dans ce but, l'invention a essentiellement pour objet un joint d'étanchéité et d'assemblage entre deux parois délimitant une enceinte sous vide, ce joint comportant une barrière métallique partiellement liquide ou très malléable, reliant les deux parois, des parties en matière élastique étant disposées de part et d'autre de ladite barrière métallique. To this end, the subject of the invention is essentially a seal and assembly between two walls delimiting a vacuum enclosure, this seal comprising a partially liquid or very malleable metal barrier, connecting the two walls, parts made of material elastic being arranged on either side of said metal barrier.
L'invention fournit ainsi un joint composite, ayant une résistance mécanique suffisante tout en étant déformable transversalement et cintrable, le contact avec les deux parois et l'assemblage des deux parois étant assurés par application de l'effet dit de "Magdebourg", du fait que ces parois sont soumises d'un côté à la pression atmosphérique et de l'autre côté à une pression pratiquement nulle, compte tenu de ce que le vide règne entre les deux parois. The invention thus provides a composite joint, having sufficient mechanical strength while being transversely deformable and bendable, the contact with the two walls and the assembly of the two walls being ensured by application of the so-called "Magdeburg" effect, the fact that these walls are subjected on one side to atmospheric pressure and on the other side to a practically zero pressure, taking into account that the vacuum prevails between the two walls.
Suivant une forme de réalisation préférée de l'invention, le joint comprend un corps en matière élastique, dans lequel est noyée une âme métallique mince dont les bords longitudinaux font saillie au fond de gorges creusées le long de deux faces opposées du corps et remplies de métal liquide, formant deux cordons entrant en contact avec les parois à assembler. La barrière métallique continue résulte ainsi de la combinaison de l'âme mince et des deux cordons liquides, constitués notamment de mercure. According to a preferred embodiment of the invention, the seal comprises a body of elastic material, in which a thin metallic core is embedded, the longitudinal edges of which protrude from the bottom of grooves dug along two opposite faces of the body and filled with liquid metal, forming two beads coming into contact with the walls to be assembled. The continuous metal barrier thus results from the combination of the thin core and the two liquid beads, made in particular of mercury.
L'âme est de préférence réalisée au moyen d'un feuillard de cuivre ou de plomb, ces métaux ne risquant pas de produire des effets électrochimiques au contact du mercure.AvantagEusement, l'âme métallique mince est de section droite et perpendiculaire aux parois à assembler, les bords longitudinaux de ladite âme n'entrant pas en contact avec ces parois et étant novés dans le métal liquide, notamment mercure.The core is preferably made by means of a copper or lead strip, these metals not likely to produce electrochemical effects in contact with mercury. Advantageously, the thin metallic core is of cross section and perpendicular to the walls to assemble, the longitudinal edges of said core not coming into contact with these walls and being innovated in liquid metal, in particular mercury.
Grâce à ces dispositions, tout flambage du feuillard métallique est impossible, la compression s'exerçant uniquement sur le mercure. Le corps du joint, quant à lui, peut être réalisé en élastomère ou en silicone, et formé par coulée ou par extrusion.Thanks to these provisions, any buckling of the metal strip is impossible, the compression being exerted only on mercury. The body of the seal, meanwhile, can be made of elastomer or silicone, and formed by casting or by extrusion.
Suivant une autre forme de réalisation possible du joint objet de l'invention, celui-ci comprend un corps en matière élastique, dans lequel est noyée une âme métallique mince très malléable, dont les bords longitudinaux sont brasés ou soudés aux parois à assembler. L'âme très malléable réalise ici à elle seule toute la barrière métallique. Avantageusement, cette âme métallique mince est un feuillard plié "en accordéon" sur toute sa section, excepté ses bords qui sont brasés ou soudés, ce qui rend ladite âme très déformable, à la fois en section et dans le sens d'un cintrage notamment pour "suivre" des angles. According to another possible embodiment of the joint which is the subject of the invention, it comprises a body of elastic material, in which is embedded a thin, very malleable metallic core, the longitudinal edges of which are brazed or welded to the walls to be assembled. The very malleable core alone achieves the entire metal barrier here. Advantageously, this thin metallic core is a strip folded "in accordion" over its entire section, except for its edges which are brazed or welded, which makes said core very deformable, both in section and in the direction of bending in particular. to "follow" angles.
Le joint objet de l'invention peut, suivant encore une autre forme de réalisation, comprendre un corps rigide notamment métallique, présentant sur deux faces opposées des paires de gorges longitudinales recevant des joncs élastiques parallèles, délimitant des cordons de métal liquide, notamment de mercure, entrant en contact avec les parois à assembler. Comme dans la première forme de réalisation, le mercure est ici confiné entre des parties élastiques, qui dans le cas présent ne réalisent cependant pas tout le corps du joint. The joint which is the subject of the invention may, according to yet another embodiment, comprise a rigid body, in particular metallic, having on two opposite faces pairs of longitudinal grooves receiving parallel elastic rods, delimiting beads of liquid metal, in particular mercury , coming into contact with the walls to be assembled. As in the first embodiment, the mercury is here confined between elastic parts, which in the present case do not however make up the entire body of the seal.
Dans tous les cas, le mercure présente l'avantage de pouvoir réaliser aussi une jonction parfaitement étanche entre les deux extrémités d'un joint refermé sur luimême, par exemple pour suivre entièrement le contour d'un panneau de forme rectangulaire. In all cases, mercury has the advantage of being able to also make a perfectly sealed junction between the two ends of a seal closed on itself, for example to fully follow the outline of a panel of rectangular shape.
De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, quelques formes d'exécution de ce joint d'étanchéité et s'assemblage entre deux parois délimitant une enceinte sous vide

Comme le montre la figure 1, le joint d'étanchéité et d'assemblage objet de l'invention, désigné dans son ensemble par le repère 1, est destiné à être monté entre deux parois planes parallèles 2 et 3 qui délimitent une enceinte sous vide 4, plus particulièrement à la périphérie de ces parois 2 et 3. Dans cette première forme de réalisation, le joint 1, ayant une section rectangulaire, comprend un corps 5 en élastomère ou en silicone, dans lequel est noyée une âme métallique mince 6, perpendiculaire aux plans
des parois 2 et 3, pouvant âtre un feuillard d'acier, d'aluminium,depréference de cuivre ou de plomb.Les bords
longitudinaux supérieur 6a et inférieur 6b de l'âme métallique 6 font saillie au fond de deux gorges Sa et 5b creusées le long des faces supérieure et inférieure du
corps 5 en élastomère ou en silicone, ces bords 6a et 6b n'entrant pas en contact avec les faces des parois 2 et
3. Les gorges Sa et 5b sont l'une et l'autre remplies de cordons de mercure, indiqués en 7 et 8 respectivement,
qui avec l'âme 6 réalisent une barrière métallique continue entre la paroi supérieure 2 et la paroi inférieure 3.As shown in Figure 1, the seal and assembly object of the invention, designated as a whole by the reference 1, is intended to be mounted between two parallel plane walls 2 and 3 which define a vacuum enclosure 4, more particularly at the periphery of these walls 2 and 3. In this first embodiment, the seal 1, having a rectangular section, comprises a body 5 made of elastomer or silicone, in which a thin metallic core 6 is embedded, perpendicular to the planes
walls 2 and 3, which can be a strip of steel, aluminum, preferably copper or lead.
longitudinal upper 6a and lower 6b of the metallic core 6 protrude at the bottom of two grooves Sa and 5b dug along the upper and lower faces of the
body 5 made of elastomer or silicone, these edges 6a and 6b not coming into contact with the faces of the walls 2 and
3. The grooves Sa and 5b are both filled with mercury beads, indicated in 7 and 8 respectively,
which with the core 6 produce a continuous metal barrier between the upper wall 2 and the lower wall 3.
Le mercure est injecté dans les gorges Sa et 5b après réalisation d'un vide partiel dans l'enceinte 4. Un vide plus poussé peut ensuite être réalisé, pour augmenter la pression du mercure 7 et 8 sur les parois 2 et 3 et garantir l'étanchéité. Le joint 1 ainsi mis en place
assure non seulement l'étanchéité entre les parois 2 et 3, mais aussi l'assemblage de ces parois 2 et 3 par appui cation de l'effet de "Magdebourg", la pression extérieure tendant à resserrer fortement ces deux parois de part et d'autre du joint 1.The mercury is injected into the grooves Sa and 5b after a partial vacuum has been produced in the enclosure 4. A deeper vacuum can then be produced, to increase the pressure of the mercury 7 and 8 on the walls 2 and 3 and guarantee the sealing. The seal 1 thus put in place
ensures not only the seal between walls 2 and 3, but also the assembly of these walls 2 and 3 by supporting cation of the effect of "Magdeburg", the external pressure tending to tighten strongly these two walls on the part and d other of the seal 1.
Dans la forme de réalisation illustrée par la figure 2, le joint 1' possède toujours un corps 5' de section rectangulaire, en élastomère ou en silicone, dans lequel
est noyée une âme métallique mince 9 ; cette âme 9 est un feuillard déformable, en métal très malléable, plié
"en accordéon" sur toute sa section, tandis que ses
bords 9a et 9b sont assemblés respectivement aux parois 2 et 3, par exemple par brasure à l'argent. Dans
le cas particulier d'un joint 1' à monter entre deux parois
2 et 3 en verre, l'on peut appliquer le procédé spécial suivant de brasure ou de soudure : du chlorure de platine, mélangé à de l'huile de cannelle, est étalé sur le verre on chauffe au rouge et on fait un dépôt électrolytique de cuivre, et ensuite l'on peut soit braser, soit souder les bords 9a et 9b sur le cuivre déposé électrolytiquement.In the embodiment illustrated in FIG. 2, the seal 1 ′ always has a body 5 ′ of rectangular section, made of elastomer or silicone, in which
is embedded a thin metallic core 9; this core 9 is a deformable strip, made of very malleable metal, folded
"in accordion" over its entire section, while its
edges 9a and 9b are assembled respectively to walls 2 and 3, for example by silver soldering. In
the special case of a joint 1 'to be mounted between two walls
2 and 3 in glass, the following special process of brazing or soldering can be applied: platinum chloride, mixed with cinnamon oil, is spread on the glass, heated to red and an electrolytic deposit is made of copper, and then we can either braze or weld the edges 9a and 9b on the electrolytically deposited copper.
Dans la forme de réalisation de la figure 3, le corps 10 du joint 1 est métallique ; de section générale rectangulaire, ce corps 10 présente sur sa face supérieure deux gorges longitudinales, de section sensiblement semicirculaire, recevant respectivement deux joncs élastiques parallèles 11, de section circulaire, tandis que sur sa face inférieure sont ménagées deux autres gorges longitu finales; de section semi-circulaire, recevant respectivement deux joncs élastiques parallèles 12 de section circulaire. Un premier cordon de mercure 7" remplit ltespace délimité par le corps métallique 10, les deux joncs 11 et la paroi plane supérieure 2. Un second cordon de mercure 8 remplit l'espace délimité par le corps métallique 10, les deux joncs 12 et la paroi plane inférieure 3. In the embodiment of Figure 3, the body 10 of the seal 1 is metallic; of generally rectangular section, this body 10 has on its upper face two longitudinal grooves, of substantially semicircular section, receiving respectively two parallel elastic rods 11, of circular section, while on its lower face are formed two other longitu final grooves; of semi-circular section, receiving respectively two parallel elastic rods 12 of circular section. A first mercury bead 7 "fills the space delimited by the metal body 10, the two rods 11 and the upper planar wall 2. A second mercury bead 8 fills the space delimited by the metal body 10, the two rods 12 and the lower flat wall 3.
Comme le montrent les figures 4 et 5, le joint I précédemment décrit peut réaliser l'étanchéité à la périphérie de l'âme centrale d'un panneau de construction, âme formée de deux parois métalliques en t8le mince 2 et 3 situées de part et d'autre de l'enceinte sous vide 4 remplie d'une structure alvéolaire en "nid d'abeille" 13. As shown in FIGS. 4 and 5, the gasket I described above can seal the periphery of the central core of a construction panel, a core formed by two thin-walled metal walls 2 and 3 located on the side and on the other side of the vacuum enclosure 4 filled with a honeycomb "13 honeycomb" structure.
Le panneau complet comprend encore une première épaisseur de béton 14 constituant le parement de la paroi métallique 2, et une seconde épaisseur de béton 15 constituant le parement de la paroi métallique 3. On comprend que le joint 1 assure ici l'assemblage, par l'effet de "Magdebourg" des parties symétriques intérieure et extérieure du panneau, tout en maintenant l'âme de ce panneau sous vide pour réaliser son isolation thermique.The complete panel also comprises a first thickness of concrete 14 constituting the facing of the metal wall 2, and a second thickness of concrete 15 constituting the facing of the metal wall 3. It is understood that the joint 1 here assures the assembly, by l 'Magdeburg effect' of the inner and outer symmetrical parts of the panel, while maintaining the soul of this panel under vacuum to achieve its thermal insulation.
L'âme métallique mince 6 du joint 1, ou l'âme 9 dans le cas d'utilisation du joint 1' selon la figure 2, est facilement déformable aux angles du panneau, ce qui permet d'utiliser un joint unique que l'on cintre pour suivre tout le contour du panneau, comme l'illustre la figure 5. The thin metallic core 6 of the joint 1, or the core 9 in the case of the use of the joint 1 'according to FIG. 2, is easily deformable at the corners of the panel, which makes it possible to use a single joint which the we bend to follow the entire outline of the panel, as illustrated in Figure 5.
A la jonction des deux extrémités du joint 1 refermé sur lui-m#me, la continuité de l'étanchéité est assurée par un petit cordon transversal de mercure 16, qui réalise un "remplissage" parfait en reliant les deux cordons de mercure principaux 7 et 8. At the junction of the two ends of the seal 1 closed on itself, the continuity of the seal is ensured by a small transverse bead of mercury 16, which achieves a perfect "filling" by connecting the two main mercury cords 7 and 8.
Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce joint d'étanchéité et d'assemblage qui ont été décrites ci-dessus, à titre d'exemples ; elle en embrasse, au contraire, toutes les variantes de réalisation fondées sur le même principe, quels que soient notamment les matériaux constitutifs du joint qui peuvent être remplacés par tous équivalents, et quelles que soient aussi les applications de ce joint, évidemment non limitées aux panneaux de construction de bâtiment mais incluant également les vitrages isolants, les capteurs solaires, etc... It goes without saying that the invention is not limited to the sole embodiments of this seal and assembly which have been described above, by way of examples; on the contrary, it embraces all of the variant embodiments based on the same principle, whatever the materials constituting the seal which may be replaced by any equivalent, and whatever the applications of this seal, obviously not limited to building construction panels but also including insulating glass, solar collectors, etc.
