Definitions

  • Glazing panel with peripheral gasket and corresponding manufacturing method Glazing panel with peripheral gasket and corresponding manufacturing method.
  • the field of the invention is that of glazing panels comprising glass sheets delimiting internal spaces also called multiple glazing panels.
  • the invention relates more particularly to the peripheral seals of these multiple glazing panels.
  • These panels can be used in any type of application such as utility glazing, glazing for vehicles or buildings.
  • a glazing panel concerned by the invention is for example an insulating glass panel (or "Insulating glass units" in English).
  • Such an insulating glazing panel conventionally comprises a first and a second glass sheet associated together via at least one spacer or spacer which holds them parallel at a distance from one another.
  • the panel is closed at its periphery through a peripheral seal so that the space between the glass sheets, also called internal space is completely closed.
  • the internal space can trap a gas slide, for example but not exclusively dry air, argon (Ar), krypton (Kr), xenon (Xe), sulfur hexafluoride (SF) 6 ) or even a mixture of some of these gases.
  • a gas slide for example but not exclusively dry air, argon (Ar), krypton (Kr), xenon (Xe), sulfur hexafluoride (SF) 6 ) or even a mixture of some of these gases.
  • the transfer of energy through an insulating panel according to this conventional structure is reduced, because of the presence of the gas strip in the internal space with respect to a single sheet of glass.
  • the internal space can also be emptied of any gas, it is called vacuum glazing. Energy transfer through a vacuum insulating glazing panel is greatly reduced by the vacuum space.
  • a vacuum glazing panel is typically composed of at least two glass sheets separated by a space in which a vacuum has been made. Such glazing is conventionally used for its high thermal insulation properties.
  • the thickness of the vacuum space is typically from 80 ⁇ to 800 ⁇ .
  • the pressure inside the glazing is generally of the order of 10-3 mbar or even lower.
  • a seal is placed at the periphery of the two glass sheets and the vacuum is created inside the glazing unit by means of a pump.
  • spacers are placed regularly (for example in the form of a matrix) between the two glass panels.
  • at least one of the two glass sheets is covered by a low-emissivity layer having an emissivity ideally less than 0.05.
  • Spacers usually have a cylindrical or spherical shape, we speak of pillars. Today, these spacers are generally metallic and thus create thermal leaks in the glazing panel. In order to maintain a thermal transmission coefficient U of less than 0.6W / m2K, the total area of the spacers in contact with the glass should be less than 1% of the area of the vacuum glazing panel.
  • a first type of seal (the most common) is a seal based on a welding glass whose melting temperature is lower than that of the glass panes of the glass.
  • the implementation of this type of seal limits the choice of low-emissivity layers to those which are not affected by the thermal cycle necessary for the implementation of the glass to be welded. say to those who withstand a temperature of up to 350 ° C.
  • this type of seal based on welding glass being only very slightly deformable, it does not allow to take over the effects of differential expansion between the glass panel of the inner side glazing and the glass panel of the outer side glazing when these are subject to large temperature differences (eg 40 ° C). Large stresses are then induced at the periphery of the glazing and can lead to breakage of the glass panels of the glazing.
  • a second type of gasket comprises a metal gasket, for example a metal strip of a thin thickness ( ⁇ 500 ⁇ m) welded to the periphery of the glazing via a bonding sub-layer at least partially covered by a protective layer.
  • a solderable material of the type solder of tin alloy is important advantage of this second type of seal with respect to the first type of seal.
  • No. 5,227,206 discloses a first embodiment of a peripheral seal of the second type for vacuum glazing.
  • the seal is a metal strip which has a substantially U-shaped section whose two parallel wings are connected to each other via a base which can be curved or straight. The two wings sandwich the two sheets of glass.
  • the final shaping of the U-shaped strip must be done around the two glass panels. Indeed, it is not possible to place the two sheets of glass and the spacers on a U-section frame that is already closed. Thus, it is not possible to separate the step of manufacture and insertion of the strip gasket in the panel of the assembly of the glass sheets of the glazing panel (which involves assembly times and cost more high). Furthermore, the metal strip forms a thermal bridge on the periphery of the glazing between the outside and the inside of the glazing. This has the effect of damaging the overall insulation performance of the glazing panel. Moreover, unlike a multiple glazing panel
  • Patent No. EP2099997B1 presents a second embodiment of a peripheral seal of the second type for vacuum glazing.
  • the seal also has a substantially U-shaped section whose two parallel wings are connected to each other via a base that can be curved or straight. Both wings are sandwiched by the two sheets of glass.

Description

Panneau de vitrage avec joint d'étanchéité périphérique et procédé de fabrication correspondant.  Glazing panel with peripheral gasket and corresponding manufacturing method.
1. Domaine de l'invention 1. Field of the invention
Le domaine de l'invention est celui des panneaux de vitrage comprenant des feuilles de verre délimitant des espaces internes également appelés panneaux de vitrage multiple. L'invention concerne plus particulièrement les joints d'étanchéité périphériques de ces panneaux de vitrage multiples. The field of the invention is that of glazing panels comprising glass sheets delimiting internal spaces also called multiple glazing panels. The invention relates more particularly to the peripheral seals of these multiple glazing panels.
Ces panneaux peuvent être utilisés dans tout type d'application tels que les vitrages utilitaires, les vitrages pour véhicules ou pour bâtiments. These panels can be used in any type of application such as utility glazing, glazing for vehicles or buildings.
2. Solutions de l'art antérieur Un panneau de vitrage concerné par l'invention est par exemple un panneau de vitrage isolant (ou "Insulating glass units" en anglais). 2. Solutions of the Prior Art A glazing panel concerned by the invention is for example an insulating glass panel (or "Insulating glass units" in English).
Un tel panneau de vitrage isolant comprend de manière classique une première et une seconde feuille de verre associées ensemble par l'intermédiaire d'au moins un espaceur ou intercalaire qui les maintient parallèles à une certaine distance l'une de l'autre. Le panneau est refermé en sa périphérie grâce à un joint d'étanchéité périphérique de sorte que l'espace entre les feuilles de verre, également appelé espace interne est complètement fermé. Such an insulating glazing panel conventionally comprises a first and a second glass sheet associated together via at least one spacer or spacer which holds them parallel at a distance from one another. The panel is closed at its periphery through a peripheral seal so that the space between the glass sheets, also called internal space is completely closed.
L'espace interne peut emprisonner une lame de gaz, par exemple mais non exclusivement de l'air sec, de l'argon (Ar), du krypton (Kr), du xénon (Xe), de l'hexafluorure de soufre (SF6) ou même un mélange de certains de ces gaz. Le transfert d'énergie à travers un panneau isolant selon cette structure classique est réduit, du fait de la présence de la lame de gaz dans l'espace interne par rapport à une simple feuille de verre. L'espace interne peut également être vidé de tout gaz, on parle alors de vitrage sous vide. Le transfert d'énergie à travers un panneau de vitrage isolant sous vide est grandement réduit par l'espace de vide. The internal space can trap a gas slide, for example but not exclusively dry air, argon (Ar), krypton (Kr), xenon (Xe), sulfur hexafluoride (SF) 6 ) or even a mixture of some of these gases. The transfer of energy through an insulating panel according to this conventional structure is reduced, because of the presence of the gas strip in the internal space with respect to a single sheet of glass. The internal space can also be emptied of any gas, it is called vacuum glazing. Energy transfer through a vacuum insulating glazing panel is greatly reduced by the vacuum space.
Un panneau de vitrage sous vide est typiquement composé d'au moins deux feuilles de verre séparées par un espace dans lequel a été réalisé un vide. Un tel vitrage est classiquement utilisé pour ses propriétés d'isolation thermique élevée. L'épaisseur de l'espace sous vide est typiquement de 80 μιη à 800 μιη. Afin d'atteindre de hautes performances d'isolation, la pression à l'intérieur du vitrage est généralement de l'ordre de 10-3 mbar ou même inférieure. Afin d'obtenir une telle pression à l'intérieur du vitrage, un joint d'étanchéité est placé à la périphérie des deux feuilles de verre et le vide est créé à l'intérieur du vitrage grâce à une pompe. Pour éviter que le vitrage ne s'effondre sous la pression atmosphérique (due à la différence de pression entre l'intérieur et l'extérieur du vitrage), des espaceurs sont placés de manière régulière (par exemple sous la forme d'une matrice) entre les deux panneaux de verre. Généralement au moins une des deux feuilles de verre est recouverte par une couche basse-émissivité ayant une émissivité idéalement inférieure à 0,05. A vacuum glazing panel is typically composed of at least two glass sheets separated by a space in which a vacuum has been made. Such glazing is conventionally used for its high thermal insulation properties. The thickness of the vacuum space is typically from 80 μιη to 800 μιη. In order to achieve high insulation performance, the pressure inside the glazing is generally of the order of 10-3 mbar or even lower. In order to obtain such a pressure inside the glazing, a seal is placed at the periphery of the two glass sheets and the vacuum is created inside the glazing unit by means of a pump. To prevent the glazing from collapsing under atmospheric pressure (due to the pressure difference between the inside and the outside of the glazing), spacers are placed regularly (for example in the form of a matrix) between the two glass panels. Generally at least one of the two glass sheets is covered by a low-emissivity layer having an emissivity ideally less than 0.05.
Les espaceurs ont généralement une forme cylindrique ou sphérique, on parle de piliers. Aujourd'hui, ces espaceurs sont généralement métalliques et créent donc des fuites thermiques dans le panneau de vitrage. Afin de maintenir un coefficient de transmission thermique U inférieur à 0,6W/m2K, la surface totale des espaceurs en contact avec le verre doit représenter moins de 1% de la surface du panneau de vitrage sous vide. Spacers usually have a cylindrical or spherical shape, we speak of pillars. Today, these spacers are generally metallic and thus create thermal leaks in the glazing panel. In order to maintain a thermal transmission coefficient U of less than 0.6W / m2K, the total area of the spacers in contact with the glass should be less than 1% of the area of the vacuum glazing panel.
Différentes technologies de joints d'étanchéité existent, chacune présentant certains inconvénients. Un premier type de joint (le plus répandu) est un joint à base d'un verre à souder dont la température de fusion est inférieure à celle du verre des panneaux de verre du vitrage. La mise en œuvre de ce type de joint limite le choix des couches basse-émissivités à celles qui ne sont pas altérées par le cycle thermique nécessaire à la mise en œuvre du verre à souder, c'est à dire à celles qui résistent à une température pouvant aller jusqu'à 350°C. De plus, ce type de joint à base de verre à souder n'étant que très peu déformable, il ne permet pas de reprendre les effets des dilatations différentielles entre le panneau de verre du vitrage coté intérieur et le panneau de verre du vitrage coté extérieur lorsque ceux-ci sont soumis à de grandes différences de température (par exemple 40°C). Des contraintes assez importantes sont alors induites à la périphérie du vitrage et peuvent entraîner des casses des panneaux de verre du vitrage. Different sealing technologies exist, each with certain disadvantages. A first type of seal (the most common) is a seal based on a welding glass whose melting temperature is lower than that of the glass panes of the glass. The implementation of this type of seal limits the choice of low-emissivity layers to those which are not affected by the thermal cycle necessary for the implementation of the glass to be welded. say to those who withstand a temperature of up to 350 ° C. In addition, this type of seal based on welding glass being only very slightly deformable, it does not allow to take over the effects of differential expansion between the glass panel of the inner side glazing and the glass panel of the outer side glazing when these are subject to large temperature differences (eg 40 ° C). Large stresses are then induced at the periphery of the glazing and can lead to breakage of the glass panels of the glazing.
Un second type de joint comprend un joint métallique, par exemple un feuillard métallique d'une épaisseur mince (<500μιη) soudé en périphérie du vitrage par l'intermédiaire d'une sous-couche d'accrochage recouverte au moins partiellement par une couche d'un matériau brasable de type soudure tendre d'alliage d'étain. Un avantage important de ce second type de joint par rapport au premier type de joint est qu'il peut se déformer pour reprendre les dilatations différentielles créées entre les deux panneaux de verre. Il existe différents types de sous-couches d'accrochage sur le panneau de verre. A second type of gasket comprises a metal gasket, for example a metal strip of a thin thickness (<500 μm) welded to the periphery of the glazing via a bonding sub-layer at least partially covered by a protective layer. a solderable material of the type solder of tin alloy. An important advantage of this second type of seal with respect to the first type of seal is that it can be deformed to take up the differential expansions created between the two glass panels. There are different types of underlays hanging on the glass panel.
Le brevet n°US5 ,227,206 présente un premier exemple de réalisation d'un joint d'étanchéité périphérique du second type pour vitrage sous vide. Selon cet exemple, le joint est un feuillard métallique qui présente une section substantiellement en forme de U dont les deux ailes parallèles sont connectées l'une à l'autre via une base qui peut être courbée ou droite. Les deux ailes prennent en sandwich les deux feuilles de verre. No. 5,227,206 discloses a first embodiment of a peripheral seal of the second type for vacuum glazing. According to this example, the seal is a metal strip which has a substantially U-shaped section whose two parallel wings are connected to each other via a base which can be curved or straight. The two wings sandwich the two sheets of glass.
Cependant, dans le cadre de ce premier exemple la mise en forme finale du feuillard en U doit se faire autour des deux panneaux de verre. En effet, il n'est pas possible de placer les deux feuilles de verre ainsi que les espaceurs sur un cadre à section en U qui est déjà fermé. Ainsi, il n'est pas possible de séparer l'étape de fabrication et d'insertion du joint feuillard dans le panneau de celle d'assemblage des feuilles de verre du panneau de vitrage (ce qui implique des temps d'assemblage et coût plus élevés). Par ailleurs, le feuillard métallique forme un pont thermique sur la périphérie du vitrage entre l'extérieur et l'intérieure du vitrage. Ceci a pour conséquence de détériorer les performances globales d'isolation du panneau de vitrage. Par ailleurs, contrairement à un panneau de vitrage multipleHowever, in the context of this first example, the final shaping of the U-shaped strip must be done around the two glass panels. Indeed, it is not possible to place the two sheets of glass and the spacers on a U-section frame that is already closed. Thus, it is not possible to separate the step of manufacture and insertion of the strip gasket in the panel of the assembly of the glass sheets of the glazing panel (which involves assembly times and cost more high). Furthermore, the metal strip forms a thermal bridge on the periphery of the glazing between the outside and the inside of the glazing. This has the effect of damaging the overall insulation performance of the glazing panel. Moreover, unlike a multiple glazing panel
« classique » remplit de gaz ou d'air sec, selon cette solution le joint feuillard n'est pas protégé par les deux feuilles de verres, ce qui induit un risque de perforation ou de déchirement du joint pouvant entraîner des fuites et peut être gênant pour l'installation du vitrage dans son châssis. Le brevet n°EP2099997Bl présente un second exemple de réalisation d'un joint d'étanchéité périphérique du second type pour vitrage sous vide. Selon cet exemple, le joint présente également une section substantiellement en forme de U dont les deux ailes parallèles sont connectées l'une à l'autre via une base qui peut être courbée ou droite. Les deux ailes sont prisent en sandwich par les deux feuilles de verre. "Conventional" fills with gas or dry air, according to this solution the band seal is not protected by the two sheets of glass, which induces a risk of perforation or tearing of the seal can cause leaks and can be annoying for the installation of the glazing in its chassis. Patent No. EP2099997B1 presents a second embodiment of a peripheral seal of the second type for vacuum glazing. According to this example, the seal also has a substantially U-shaped section whose two parallel wings are connected to each other via a base that can be curved or straight. Both wings are sandwiched by the two sheets of glass.
Outre les inconvénients cités ci-dessus, dans le cadre de ce second exemple, il est nécessaire de mettre en œuvre une étape supplémentaire de jonction des deux feuillards. In addition to the disadvantages mentioned above, in the context of this second example, it is necessary to implement an additional step of joining the two strips.
Par ailleurs, lors de l'assemblage d'un panneau de vitrage sous vide, certaines étapes impliquent réchauffement localisé des feuilles de verre ce qui conduit à des variations des dimensions (par dilatation ou rétraction thermique) d'une des feuilles de verre par rapport à l'autre feuille de verre. Ces variations de dimensions peuvent nuire à l'intégrité du joint périphérique et peuvent parfois conduire à une désolidarisation du joint au panneau. Moreover, during the assembly of a vacuum glazing panel, certain steps involve localized heating of the glass sheets, which leads to variations in the dimensions (by thermal expansion or shrinkage) of one of the glass sheets relative to to the other glass sheet. These variations in size can affect the integrity of the peripheral seal and can sometimes lead to a separation of the seal to the panel.

4. Exposé de l'invention Conformément à un mode de réalisation particulier, l'invention concerne un joint d'étanchéité périphérique pour panneau de vitrage, en particulier panneau de vitrage isolant, comprenant au moins une première et une seconde feuilles de verre associées ensemble par l'intermédiaire d'au moins un espaceur qui les maintient à une certaine distance l'une de l'autre et, entre lesdites au moins deux feuilles de verre, au moins un espace interne est fermé par le joint d'étanchéité périphérique disposé à la périphérie des feuilles de verre, autour dudit espace interne. 4. DESCRIPTION OF THE INVENTION In accordance with a particular embodiment, the invention relates to a peripheral seal for a glazing panel, particular insulating glazing panel, comprising at least first and second glass sheets associated together via at least one spacer which holds them at a distance from each other and, between said at least two glass sheets, at least one internal space is closed by the peripheral seal disposed at the periphery of the glass sheets, around said internal space.
Selon l'invention, la section du joint d'étanchéité comprenant une portion médiane et des première et seconde portions d'extrémité respectivement solidarisées aux première et seconde feuilles de verre. Selon l'invention, la section du joint d'étanchéité forme au moins une cavité en regard avec au moins une des tranches des première et seconde feuilles de verre. According to the invention, the section of the seal comprising a middle portion and first and second end portions respectively secured to the first and second glass sheets. According to the invention, the section of the seal forms at least one cavity facing at least one of the slices of the first and second sheets of glass.
Bien entendu, les rôles des première et seconde feuilles de verre sont interchangeables. Bien entendu, on entend par verre, tous les types de verres et matériaux transparents équivalents tels que les verres minéraux et les verres organiques. Le verre minéral peut être constitué indifféremment d'un ou plusieurs types de verres connus comme les verres sodo-calcique, les verres au bore, les verres cristallins et semi-cristallins. Le verre organique peut être un polymère ou un copolymère transparent thermodur ou thermoplastique rigide tel que, par exemple, une résine de synthèse polycarbonate, polyester ou polyvinylique transparente. Of course, the roles of the first and second glass sheets are interchangeable. Of course, glass means all types of glasses and equivalent transparent materials such as mineral glasses and organic glasses. The mineral glass can be constituted indifferently of one or more types of known glasses such as soda-lime glasses, boron glasses, crystalline and semi-crystalline glasses. The organic glass may be a thermoset or rigid thermoplastic transparent polymer or copolymer such as, for example, a clear polycarbonate, polyester or polyvinyl synthetic resin.
Le principe général de l'invention repose sur la réalisation d'au moins une cavité en regard avec au moins une des tranches des première et seconde feuilles de verre. The general principle of the invention is based on the production of at least one cavity facing at least one of the slices of the first and second glass sheets.
Ainsi, la technique de solidarisation du joint périphérique au panneau selon l'invention offre une protection accrue du joint périphérique et notamment cette technique permet de limiter les risques de casse ou de désolidarisation du panneau du joint d' étanchéité en cas de dilatation ou rétraction thermique d'au moins une portion d'au moins une des feuilles de verre. Thus, the technique of joining the peripheral gasket to the panel according to the invention offers increased protection of the peripheral seal and in particular, this technique makes it possible to limit the risk of breakage or separation of the gasket panel in the event of expansion or thermal shrinkage of at least a portion of at least one of the glass sheets.
En outre, le joint peut être protégé par un cordon de polymère (de type silicone, PU, ...) de la même manière que dans les panneaux de vitrage multiples classiques. Ainsi, une telle technique permet un montage du panneau de vitrage sur un châssis classique pour vitrage multiple. In addition, the seal may be protected by a bead of polymer (silicone, PU, ...) in the same manner as in conventional multiple glazing panels. Thus, such a technique allows a mounting of the glazing panel on a conventional frame for multiple glazing.
Par ailleurs, cette technique de solidarisation du joint permet d'obtenir des performances d'isolation thermiques du panneau de vitrage améliorées grâce notamment à la réduction des pertes dues aux effets de bord. Furthermore, this technique of securing the joint provides improved thermal insulation performance of the glazing panel thanks in particular to the reduction of losses due to edge effects.
Préférentiellement, le joint d'étanchéité comprend en outre des moyens d'obturation élastique de ladite cavité sur au moins une portion du joint d'étanchéité périphérique. Preferably, the seal further comprises elastic closure means of said cavity on at least a portion of the peripheral seal.
Lors du processus d'assemblage du panneau, afin de nettoyer les faces internes au panneau des première et seconde feuille de verre, par exemple, pour obtenir un gaz isolant plus pur dans l'espace interne d'un panneau de double vitrage ou afin d'améliorer les performances de vide dans un panneau de vitrage sous vide, on peut mettre en œuvre une étape de dégazage ou encore une étape de de circulation d'un flux liquide nettoyant tel qu'une solution aqueuse contenant un détergeant basique, comme le RBS50 par exemple, ou encore tel qu'un alcool isopropylique, ayant un point d'évaporation faible facilement atteignable en chauffant le vitrage dans une étuve, par exemple. During the assembly process of the panel, in order to clean the internal faces of the panel of the first and second glass sheets, for example, to obtain a purer gas insulator in the internal space of a double glazing panel or to to improve the vacuum performance in a vacuum glazing panel, it is possible to implement a degassing step or a step of circulating a liquid cleaning stream such as an aqueous solution containing a basic detergent, such as the RBS50 for example, or such as isopropyl alcohol, having a low evaporation point easily achievable by heating the glazing in an oven, for example.
On entend par face externe au panneau d'une feuille de verre, la face qui n'est pas connexe avec l'espace interne. De même, on entend par face interne au panneau d'une feuille de verre, l'autre face (celle qui est pas connexe avec l'espace externe). Tel qu'illustré par la figure 2, l'étape de dégazage est par exemple réalisée au moyen de la circulation d'un flux d'un gaz oxydant tel que l'oxyde nitreux (N20), vapeur d'eau, air, l'ozone (03) 12 entre les première et seconde feuilles de verre 5 du panneau de vitrage. Préférentiellement, le dégazage est réalisé une fois que le panneau est fermé de manière étanche grâce au joint d'étanchéité périphérique 1. Préférentiellement, le flux de gaz oxydant entre dans l'espace interne du panneau via un tube d'entrée 11 et est évacué de l'espace interne via un tube de sortie 13, lesdits tubes étant par exemple solidarisé respectivement à des première et seconde ouvertures prévues dans le joint d'étanchéité. The outer face of the panel of a glass sheet means the face which is not connected with the internal space. Similarly, the inner face of the panel of a sheet of glass, the other side (the one that is not connected with the external space). As illustrated in FIG. 2, the degassing step is for example carried out by means of the circulation of a flow of an oxidizing gas such as nitrous oxide (N 2 O), water vapor, air , ozone (0 3 ) 12 between the first and second glass sheets 5 of the glazing panel. Preferably, the degassing is carried out once the panel is closed in a sealed manner thanks to the peripheral seal 1. Preferably, the flow of oxidizing gas enters the internal space of the panel via an inlet tube 11 and is evacuated the internal space via an outlet tube 13, said tubes being for example secured respectively to first and second openings provided in the seal.
Cependant, la cavité en regard avec au moins une des tranches des première et seconde feuilles de verre formée par la section du joint d'étanchéité constitue une possibilité de fuite pour au moins une partie du flux de gaz oxydant tel que l'oxyde nitreux (N20), vapeur d'eau, air, l'ozone (O3) 12 ou une partie du flux liquide nettoyant, partie qui ne passe donc pas par l' espace interne du panneau, ce qui réduit l'efficacité du dégazage ou de l'étape de nettoyage par circulation d'un flux liquide nettoyant. However, the cavity opposite at least one of the slices of the first and second sheets of glass formed by the section of the seal constitutes a possibility of leakage for at least a portion of the flow of oxidizing gas such as nitrous oxide ( N 2 0), water vapor, air, ozone (O3) 12 or a part of the liquid cleaning stream, part that does not pass through the internal space of the panel, which reduces the effectiveness of degassing or the cleaning step by circulation of a liquid cleaning stream.
Ainsi, la mise en œuvre des moyens d'obturation élastiques de cette cavité permet d'améliorer l'efficacité d'un dégazage ou de l'étape de nettoyage par circulation d'un flux liquide nettoyant. En outre, du fait qu'ils sont élastiques, les moyens d'obturation permettent à la cavité de conserver sa fonction d'absorption d'une éventuelle dilatation ou rétractation thermique d'au moins une portion d'au moins une des feuilles de verre. En effet, si une feuille de verre voit ses dimensions, dans le plan du panneau, s'agrandir par dilatation thermique, alors cette feuille de verre pousse sur les moyens d'obturation élastiques qui se déforment alors de sorte à accueillir l'augmentation des dimensions de la feuille de verre. Thus, the implementation of the elastic closure means of this cavity makes it possible to improve the efficiency of a degassing or the cleaning step by circulation of a cleaning liquid flow. In addition, because they are elastic, the sealing means allow the cavity to retain its function of absorbing a possible expansion or thermal shrinkage of at least a portion of at least one of the glass sheets . Indeed, if a glass sheet sees its dimensions, in the plane of the panel, expand by thermal expansion, then this sheet of glass pushes on the elastic closure means which then deform to accommodate the increase in dimensions of the glass sheet.
Avantageusement, les moyens d'obturation élastique comprennent au moins une portion de lame formant un ressort de hauteur identique à la hauteur de ladite cavité. Advantageously, the elastic closure means comprise at least one blade portion forming a spring height identical to the height of said cavity.
Avantageusement, la portion de lame est en cuivre. Advantageously, the blade portion is made of copper.
Avantageusement, plusieurs portions de lame sont positionnées à intervalle régulier le long des côtés parallèles au flux de gaz. Par exemple, la première portion de lame peut être placée à proximité du coin puis les suivantes peuvent être espacées entre 50 et 100mm l'une de l'autre. Advantageously, several blade portions are positioned at regular intervals along the sides parallel to the gas flow. For example, the first blade portion can be placed near the corner and the following can be spaced between 50 and 100mm from each other.
Selon une caractéristique avantageuse de l'invention, les moyens d'obturation élastique sont réalisés par préformage de la portion médiane de la section du joint d'étanchéité. Avantageusement, le joint d'étanchéité présente une section en forme de S comprenant une première aile solidarisée à la première feuille de verre et une seconde aile solidarisée à la seconde feuille de verre. According to an advantageous characteristic of the invention, the elastic closure means are made by preforming the middle portion of the section of the seal. Advantageously, the seal has an S-shaped section comprising a first wing secured to the first sheet of glass and a second wing secured to the second sheet of glass.
Avantageusement, le joint d'étanchéité présente une section en forme de U comprenant une première aile solidarisée à la première feuille de verre et une seconde aile solidarisée à la seconde feuille de verre. Advantageously, the seal has a U-shaped section comprising a first wing secured to the first sheet of glass and a second wing secured to the second sheet of glass.
Selon une caractéristique avantageuse de l'invention, dans l'espace interne règne un vide inférieur à 1 mbar. According to an advantageous characteristic of the invention, in the internal space a vacuum of less than 1 mbar prevails.

DESCRIPTION OF AN EMBODIMENT OF THE INVENTION The present invention will be described with reference to particular embodiments and with reference to certain drawings but the invention is not limited by this and is not limited only by the claims. In drawings, the size and relative dimensions of some elements may be exaggerated and may not be drawn to scale for illustrative purposes. In addition, the terms first, second, third and similar in the description and in the claims are used to distinguish between similar elements and not necessarily to describe a sequence that is temporal, spatial, for classification purposes or otherwise. It is understood that the terms thus used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of being operated in other sequences than those described or illustrated herein.

It will be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of being operated in other orientations than those described or illustrated herein.
Il est à remarquer que le terme "comprenant", utilisé dans les revendications, ne doit pas être interprété comme étant restreint aux moyens listés après celui-ci; il n'exclut pas d'autres éléments ou étapes. Il doit donc être interprété comme spécifiant la présence des éléments spécifiés, entiers, étapes ou composants référés, mais n'exclut pas la présence ou l'addition d'un élément, entier, étape ou composant, ou groupe de ceux-ci. Donc l'étendue de l'expression "un appareil comprenant les moyens A et B" ne doit pas être limitée à des appareils consistant seulement en des composants A et B. Cela veut dire qu'en ce qui concerne la présente invention, les seuls composants pertinents de l'appareil sont A et B. It should be noted that the term "comprising", used in the claims, should not be construed as being restricted to the means listed after it; it does not exclude other elements or steps. It must therefore be interpreted as specifying the presence of the specified elements, integers, steps or components referred to, but does not exclude the presence or addition of an element, integer, step or component, or group thereof. Therefore, the scope of the term "an apparatus comprising means A and B" should not be limited to apparatus consisting only of components A and B. This means that as far as the present invention is concerned, the only relevant components of the device are A and B.
Tel qu'utilisé ici et à moins d' indications contraires, par « étanchéité », il est entendu l'étanchéité à tout gaz qui pourrait être utilisé dans un double vitrage pour améliorer l'isolation (par exemple l'argon) ou l'étanchéité à l'air ou tout autre gaz présent dans l'atmosphère (dans le cas d'un vitrage sous vide). As used herein and unless otherwise indicated, "sealing" means sealing against any gas that could be used in double glazing to improve insulation (eg argon) or airtightness or other gases present in the atmosphere (in the case of vacuum glazing).
Tel qu'utilisé ici et à moins d'indications contraires, par « couche d'isolation thermique » il est entendu une couche d'oxyde métallique ayant une émissivité inférieure à 0,2, préférentiellement inférieure à 0,1 et p lus préférentiellement inférieure à 0,05. Une couche d'isolation thermique peut être par exemple l'une des couches suivantes : Planibel G, Planibel Top N, Top N+ et Top 1.0 commercialisées par la société AGC. As used herein and unless otherwise indicated, "thermal insulation layer" means a metal oxide layer having an emissivity of less than 0.2, preferably less than 0.1 and more preferably less than 0.1. at 0.05. A thermal insulation layer may be for example one of the following layers: Planibel G, Planibel Top N, Top N + and Top 1.0 marketed by AGC.
Tel qu'utilisé ici et à moins d'indications contraires le terme « espaceur » se rapporte à un ou plusieurs éléments assurant une distance relativement constante entre deux panneaux de verre adjacents. On se place ci-après dans le cas particulier d'un panneau de vitrage selon l'invention qui est un panneau de vitrage sous vide. Bien entendu, l'invention s'applique également à tout type de panneau de vitrage comprenant des feuilles de verre (deux, trois ou plus) délimitant des espaces internes (également appelés panneaux de vitrage multiple) isolants ou non isolants. Par exemple, l'invention s'applique également à un panneau de double vitrage dont l'espace interne peut emprisonner une lame de gaz, par exemple mais non exclusivement de l'air sec, de l'argon (Ar), du krypton (Kr), du xénon (Xe), de l'hexafluorure de soufre (SF6) ou même un mélange de certains de ces gaz. As used herein and unless otherwise indicated, the term "spacer" refers to one or more elements providing a relatively constant distance between two adjacent glass panels. The following is the case in particular of a glazing panel according to the invention which is a vacuum glazing panel. Of course, the invention also applies to any type of glazing panel comprising glass sheets (two, three or more) delimiting internal spaces (also called multiple glazing panels) insulating or non-insulating. For example, the invention also applies to a double glazing panel whose internal space can trap a gas blade, for example but not exclusively dry air, argon (Ar), krypton ( Kr), from xenon (Xe), sulfur hexafluoride (SF 6 ) or even a mixture of some of these gases.
Par exemple encore, l'invention s'applique également à un panneau de triple vitrage comprenant un premier espace interne dans lequel un vide est réalisé et un second espace interne comprenant une lame de gaz isolant(s). For example again, the invention also applies to a triple glazing panel comprising a first internal space in which a vacuum is formed and a second internal space comprising an insulating gas strip (s).
Bien entendu, d'autres variantes sont envisageables notamment en remplaçant une des feuilles de verre du panneau par un panneau de verre feuilleté ou par tout autre ajout ou modification. Of course, other variants are possible in particular by replacing one of the glass sheets of the panel with a laminated glass panel or by any other addition or modification.
On présente, en relation avec les figure 1, une vue globale d'un panneau de vitrage sous vide selon un mode de réalisation de l'invention. In relation to FIG. 1, an overall view of a vacuum glazing panel according to one embodiment of the invention is presented.
Le panneau de vitrage sous vide comprend des première et seconde feuilles de verre 5 (par exemple des feuilles de verre clair sodo-silico-calcique d'épaisseur 6 mm) associées ensemble par l'intermédiaire d'au moins un espaceur 8 qui les maintient à une certaine distance l'une de l'autre. Ainsi, les première et seconde feuilles de verre 5 sont séparées par un premier espace interne 4 formant une première cavité dans laquelle règne un vide inférieur à 1 mbar, par exemple égal à 10"3 mbar (obtenu par pompage dans la cavité grâce à une pompe à vide). The vacuum glazing panel comprises first and second glass sheets 5 (eg 6 mm thick soda-silico-calcium glass sheets) associated together via at least one spacer 8 which holds them together. at a certain distance from each other. Thus, the first and second glass sheets 5 are separated by a first internal space 4 forming a first cavity in which there is a vacuum of less than 1 mbar, for example equal to 10 -3 mbar (obtained by pumping into the cavity thanks to a vacuum pump).
Bien entendu, tout autre type de verre, et d'épaisseur de verre peuvent être mis en œuvre. Le panneau de vitrage sous vide comprend également une pluralité d'espaceurs 8 selon l'invention, les espaceurs étant pris en sandwich entre les première et seconde feuilles de verre 5 de manière à maintenir le premier espace entre ces feuilles de verre 5. Of course, any other type of glass, and glass thickness can be implemented. The vacuum glazing panel also comprises a plurality of spacers 8 according to the invention, the spacers being sandwiched between the first and second glass sheets 5 so as to maintain the first space between these glass sheets 5.
Par exemple, les espaceurs sont disposés entre les première et seconde feuilles de verre de sorte à former une matrice dont le pas est compris entre 20 et 80 mm et préférentiellement compris entre 30 et 60 mm. Les espaceurs 8 peuvent avoir des formes différentes telles que cylindrique, sphérique, fïlaire en forme de sablier, en forme de croix, ... For example, the spacers are arranged between the first and second sheets of glass so as to form a matrix whose pitch is between 20 and 80 mm and preferably between 30 and 60 mm. The spacers 8 may have different shapes such as cylindrical, spherical, hourglass shaped, cross-shaped, etc.
On se place dans la suite dans le cadre d'un exemple conforme à l'invention selon lequel les espaceurs 8 sont réalisés en acier AISI301 et présentent une forme de C. The following is an example of the invention according to which the spacers 8 are made of AISI301 steel and have a C shape.
L'étape de mise en forme de l'acier austénitique comprend tout d'abord une étape d'obtention d'un fil de section cylindrique par tréfilage. Bien entendu, l'étape d'obtention du fïl peut également être obtenue par extrusion à chaud dudit acier AISI301 puis tréfilage permettant d'atteindre le diamètre final du fil. The shaping step of the austenitic steel first comprises a step of obtaining a wire of cylindrical section by drawing. Of course, the step of obtaining the wire can also be obtained by hot extruding said steel AISI301 and drawing to reach the final diameter of the wire.
Par exemple, en partant d'un fil de 5mm de diamètre sur lequel on réalise le tréfilage, on obtient un fïl affiné présentant un diamètre de 1mm (ce qui représente une réduction de la section du fïl de 80%). For example, starting from a 5mm diameter wire on which the drawing is carried out, a refined film having a diameter of 1 mm is obtained (which represents a reduction of the section of the film by 80%).
L'étape de mise en forme de l'acier austénitique comprend ensuite une étape de découpe (par exemple au moyen d'une pince coupante) d'au moins une portion du fïl pour former ledit espaceur. Par exemple, la longueur de ladite portion de fïl est de 4 mm. The shaping step of the austenitic steel then comprises a cutting step (for example by means of a cutting pliers) of at least a portion of the wire to form said spacer. For example, the length of said film portion is 4 mm.
Selon un mode de mise en œuvre avantageux, l'étape de mise en forme de l'acier austénitique comprend ensuite une étape de courbure de ladite portion de fil sur au moins une de ses portions de sorte à former une portion de boucle dont le rayon de courbure maximum est de 0,5 mm. According to an advantageous embodiment, the shaping step of the austenitic steel then comprises a step of curvature of said portion of wire on at least one of its portions so as to form a portion of a loop whose radius maximum curvature is 0.5 mm.
Bien entendu, l'étape de courbure peut s'effectuer avant l'étape de découpe. Of course, the bending step can be performed before the cutting step.
Préférentiellement, la portion de fïl est une portion de cercle dont le rayon de courbure est de 0,5 mm. Preferably, the portion of fIl is a portion of a circle whose radius of curvature is 0.5 mm.
Ainsi, dans le cadre de ce second exemple, l'étape d'écrouissage est confondue avec l'étape de tréfilage. Ainsi, lors de l'opération de tréfilage, une réduction de section du fil de 80% induit une augmentation de la résistance de l'acier inoxydable AISI de 620MPa à environ 1400 MPa. Thus, in the context of this second example, the hardening step is merged with the drawing step. Thus, during the wire drawing operation, a section reduction of the wire of 80% induces an increase of the resistance of the AISI stainless steel from 620 MPa to about 1400 MPa.
Par exemple, si on utilise des espaceurs en AISI non écrouis (qui présentent donc une résistance à la compression de 620 MPa) qui ont une surface de contact équivalente à un disque de 250 μιη de rayon, un espacement de 30 mm entre ceux-ci, on obtient un panneau de vitrage sous vide présentant une valeur de coefficient U égale à 0,8 W/(m2K). For example, if non-hardened AISI spacers (which therefore have a compressive strength of 620 MPa) are used which have a contact area equivalent to a disk of 250 μm radius, a spacing of 30 mm between them a vacuum glazing panel having a U-value of 0.8 W / (m 2 K) is obtained.
Par contre, en utilisant les espaceurs selon l'invention ci-dessus mentionnés (en AISI 301 écroui et mis en forme de C) qui présentent une résistance à la compression de 1400MPa, on peut diminuer le nombre d'espaceurs en les éloignant de 50 mm tout en améliorant la valeur U est devient environ 0,5 W/(m2K). By cons, using the spacers according to the invention mentioned above (in AISI 301 hardened and shaped C) which have a compressive strength of 1400MPa, can reduce the number of spacers by moving them away from 50 mm while improving the value U is becomes about 0.5 W / (m 2 K).
Les valeurs U des vitrages sous vide sont estimées sur base d'un vitrage décrit précédemment, incluant une couche type basse émissivité. Les transmissions thermiques (valeurs U) ont été évaluées en utilisant la méthode décrite dans la publication de l'Université de Sydney : DETERMINATION OF THE OVERALL HEAT TRANSMISSION COEFFICIENT (U- VALUE) OF VACUUM GLAZING, TM.Simko, AH.Elmahdy and RE.Collins. ASHRAE Transactions, 105, pt 2, p. 1—9. 1999. The U values of the vacuum glazings are estimated on the basis of glazing previously described, including a low emissivity type layer. Thermal transmissions (U values) were evaluated using the method described in the University of Sydney publication: DETERMINATION OF THE OVERALL HEAT TRANSMISSION COEFFICIENT (U VALUE) OF VACUUM GLAZING, TM.Simko, AH.Elmahdy and RE .Collins. ASHRAE Transactions, 105, pt 2, p. 1-9. 1999.
Afin d'améliorer encore les performances en terme d'isolation thermique, une couche d'isolation thermique peut être disposée sur une surface interne d'au moins une des feuilles de verre 5. In order to further improve the performance in terms of thermal insulation, a thermal insulation layer may be disposed on an inner surface of at least one of the glass sheets 5.
Les deux feuilles de verre 5 sont assemblées de manière étanche au gaz (assurant le vide) via un joint d'étanchéité périphérique 1 placé à la périphérie des feuilles de verre 5 autour de l'espace interne 4 refermant la première cavité. Tel qu'indiqué précédemment, la figure 2 illustre le mise en œuvre d'une étape de dégazage de l'espace interne 4 du panneau de vitrage. Bien entendu, si le panneau de la figure 1 est un panneau de vitrage sous vide, l'étape de dégazage de la figure 2 pourrait être mise en œuvre dans tout autre type de panneau de vitrage conforme à l'invention. The two glass sheets 5 are gas-tightly assembled (providing vacuum) via a peripheral seal 1 placed at the periphery of the glass sheets 5 around the internal space 4 closing the first cavity. As indicated above, FIG. 2 illustrates the implementation of a degassing step of the internal space 4 of the glazing panel. Of course, if the panel of Figure 1 is a vacuum glazing panel, the degassing step of Figure 2 could be implemented in any other type of glazing panel according to the invention.
On présente, en relation avec les figure 3a et 3b, des premier 101 et second 102 joints d'étanchéité périphériques du panneau de la figure 1 respectivement selon des premier et second modes de réalisation de l'invention. In relation to FIGS. 3a and 3b, the first 101 and second 102 peripheral seals of the panel of FIG. 1 are presented respectively according to first and second embodiments of the invention.
Sur les figures 3 a et 3b ne sont représentés que des portions de la section du vitrage. Figures 3a and 3b show only portions of the section of the glazing.
Pour chacun des premier 101 et second 102 joints d' étanchéité périphériques, la section du joint d'étanchéité comprend une portion médiane et des première 1011 ; 1021 et seconde 1012 ; 1022 portions d' extrémité respectivement solidarisées aux première et seconde feuilles de verre 5. Pour chacun des premier 101 et second 102 joints d'étanchéité périphériques, la section des premier 101 et second 102 joints d'étanchéité périphériques forment respectivement des première 1013 et seconde 1023 cavités en regard avec respectivement la tranche 52 de la première feuille de verre 5 et les tranches 52 des première et seconde feuilles de verre 5. Les premier 101 et second 102 joints d'étanchéité comprennent en outre respectivement des premier 1014 et second 1024 moyens d'obturation élastique respectivement des première 1013 et seconde 1023 cavités sur au moins une portion du joint d'étanchéité périphérique 101; 102. For each of the first 101 and second 102 peripheral seals, the seal section includes a middle portion and first 1011; 1021 and second 1012; 1022 end portions respectively secured to the first and second glass sheets 5. For each of the first 101 and second 102 peripheral seals, the section of the first 101 and second 102 peripheral seals respectively form first 1013 and second 1023 cavities facing respectively the wafer 52 of the first glass sheet 5 and the wafers 52 of the first and second glass sheets 5. The first 101 and second 102 seals further comprise respectively first 1014 and second 1024 means resiliently sealing respectively the first 1013 and second 1023 cavities on at least a portion of the peripheral seal 101; 102.
Par exemple, les moyens d'obturation élastique comprennent au moins une portion de lame formant ressort 1014 ; 1024 par exemple en cuivre qui est intégrée dans la cavité. A titre d' alternative (non illustrée), les moyens d'obturation élastique 1014 ; 1024 peuvent être réalisés par préformage de la portion médiane de la section du joint 101, 102 d'étanchéité. For example, the elastic closure means comprise at least one portion of leaf spring 1014; 1024 for example copper which is integrated in the cavity. As an alternative (not shown), the elastic closure means 1014; 1024 may be made by preforming the middle portion of the seal section 101, 102 sealing.
A titre d'alternative encore (non illustrée), les moyens d'obturation élastique 1014 ; 1024 peuvent être réalisés en utilisant un matériau de composition chimique minérale élastiquement déformable de telle manière qu'il puisse absorber les éventuelles contractions et dilatations d'une ou des deux feuilles de verre. Le moyen d'obturation peut par exemple être constitué d'une tresse de fibres minérales dont le diamètre est tel qu'elle remplisse partiellement ou complètement la section de la cavité Une manière de réaliser l'invention est d'obturer la cavité sur toute sa longueur. Une autre manière de réaliser l'invention est d'obturer la cavité sur une portion de sa longueur. Le matériau utilisé sera de préférence un matériau minéral, tel que la céramique, le verre, le métal. L'utilisation de torsades de 4 - 5 mm de diamètre réalisées en fibres réfractaires d'aluminosilicate (Si02 : 56% ; A1203 : 32% ; Na20 : 3,5% ; CaO : 3% ; MgO : P/o ; ΤΊ02 ; 0,7%>) dont le diamètre est compris entre 15 et 20 μιη est une manière de réaliser l'invention. As yet another alternative (not shown), the elastic closure means 1014; 1024 can be made using a material of elastic chemical composition elastically deformable so that it can absorb any contractions and dilations of one or both sheets of glass. The sealing means may for example be constituted by a braid of mineral fibers whose diameter is such that it partially or completely fills the section of the cavity. One way of carrying out the invention is to seal the cavity over its entire length. length. Another way of carrying out the invention is to close the cavity over a portion of its length. The material used will preferably be a mineral material, such as ceramic, glass, metal. The use of 4 to 5 mm diameter twists made of aluminosilicate refractory fibers (SiO 2: 56%, Al 2 O 3: 32%, Na 2 O 3: 3.5%, CaO 3%, MgO: P / O, ΤΊO 2; 0.7%>) whose diameter is between 15 and 20 μιη is one way of carrying out the invention.
Le premier joint d'étanchéité 101 présente une section en forme de S comprenant une première aile 1011 solidarisée à la première feuille de verre et une seconde aile 1012 solidarisée à la seconde feuille de verre. The first seal 101 has an S-shaped section comprising a first flange 1011 secured to the first sheet of glass and a second flange 1012 secured to the second sheet of glass.
Le second joint d'étanchéité 102 présente une section en forme de U comprenant une première aile 1021 solidarisée à la première feuille de verre et une seconde aile 1022 solidarisée à la seconde feuille de verre. The second seal 102 has a U-shaped section comprising a first flange 1021 secured to the first sheet of glass and a second flange 1022 secured to the second sheet of glass.
En outre, les joints peuvent être protégés par un cordon de polymère de type silicone, PU, ... (non illustré) de la même manière que dans les panneaux de vitrage multiples classiques. Les premier 101 et second 102 joints d'étanchéité périphériques sont par exemple des feuillards métalliques présentant chacun une section en forme de U et comprenant chacun des première et seconde ailes. In addition, the seals may be protected by a silicone polymer bead, PU, ... (not shown) in the same manner as in conventional multiple glazing panels. The first 101 and second 102 peripheral seals are for example metal strips each having a U-shaped section and each comprising first and second wings.
Les première 1011 ; 1021 et seconde 1012 ; 1022 ailes des premier 101 et second 102 joints d'étanchéités sont solidarisées aux première et seconde feuilles de verre 5 respectivement par soudure (par exemple réalisées à l'aide d'une brasure d'étain) d'une portion de ces ailes sur des portions de couches d'adhésion 53 prévues à la périphérie des feuilles de verre correspondantes. The first 1011; 1021 and second 1012; 1022 wings of the first 101 and second 102 seals are secured to the first and second glass sheets 5 respectively by welding (for example made using a solder of tin) of a portion of these wings on portions of adhesion layers 53 provided at the periphery of the corresponding glass sheets.
Par exemple le matériau d'adhésion constituant les couches d'adhésion 53 peut être sélectionné dans le groupe composé du cuivre et de ses alliages (par exemple avec du titane et/ou du chrome), de l'aluminium et de ses alliages, du fer et de ses alliages (tel que les acier austénitiques Fe-Ni : e.g. Fer (50-55% en poids, par exemple 52% en poids), Nickel (45-50%) en poids, par exemple 48% en poids) tel que l'alliage 48), les alliages de fer comprenant les métaux suivant : Fer (53-55%) en poids, par exemple 53.5% en poids), Nickel (28-30%) en poids, par exemple 29% en poids) et Cobalt (16-18% en poids, par exemple 17% en poids), et le Kovar®), du platine et de ses alliages, du nickel et de ses alliages, de l'or et de ses alliages, de l'argent et de ses alliages, de l'arséniure de gallium et de l'étain ou de ses alliages. Cette liste n'étant pas exhaustive. For example, the adhesion material constituting the adhesion layers 53 may be selected from the group consisting of copper and its alloys (for example with titanium and / or chromium), aluminum and its alloys, iron and its alloys (such as austenitic Fe-Ni steel: eg Iron (50-55% by weight, for example 52% by weight), Nickel (45-50% by weight, for example 48% by weight) such as alloy 48), iron alloys comprising the following metals: Iron (53-55%) by weight, for example 53.5% by weight), Nickel (28-30%) by weight, for example 29% by weight cobalt (16-18% by weight, for example 17% by weight), and Kovar®), platinum and its alloys, nickel and its alloys, gold and its alloys, silver and its alloys, gallium arsenide and tin or its alloys. This list is not exhaustive.
Bien entendu, le joint d'étanchéité peut être réalisé de toute autre manière, par exemple grâce à deux feuillards métalliques soudés dans les évidements des feuilles de verre et également soudés entre eux. Par ailleurs toute autre technique de solidarisation du joint d'étanchéité au(x) évidement(s) peut être mise en œuvre sans sortir du cadre de l'invention, par exemple une soudure grâce à de la soudure de verre directement sur le verre (aucune couche d'adhésion 53 n'est nécessaire dans ce cas) ou par emboîtement à force. Of course, the seal may be made in any other way, for example by two metal strips welded into the recesses of the glass sheets and also welded together. Furthermore, any other technique for securing the seal to the recess (s) can be implemented without departing from the scope of the invention, for example a weld by means of glass welding directly on the glass ( no adhesion layer 53 is necessary in this case) or by forced fitting.
Bien entendu, selon des variantes non illustrées du mode de réalisation précité, le panneau de vitrage peut comprendre en outre une troisième feuille de verre séparée de l'une quelconque des première et seconde feuilles de verre (par exemple de la seconde feuille de verre) par un second espace afin de former une seconde cavité. Of course, according to non-illustrated variants of the aforementioned embodiment, the glazing panel may further comprise a third a glass sheet separated from any of the first and second glass sheets (e.g., the second glass sheet) by a second gap to form a second cavity.
Selon une première variante, un second un joint d'étanchéité est en outre placé à la périphérie des troisième et seconde feuilles de verre afin de maintenir le second espace (par exemple de 16mm d'épaisseur), ladite seconde cavité étant remplie d'au moins un gaz. Le gaz peut être par exemple, de l'air, de l'argon, de l'azote, du krypton, du xénon, du SF6, du C02, ou tout autre gaz isolant thermique. Selon une seconde variante, les troisième et seconde feuilles de verre sont assemblées de manière étanche au gaz (assurant le vide) via un joint d'étanchéité placé à la périphérie des feuilles de verre refermant la seconde cavité et une pluralité d'espaceurs selon l'invention sont pris en sandwich entre les troisième et seconde feuilles de verre de manière à maintenir le second espace entre ces feuilles de verre. On obtient ainsi un triple vitrage sous vide. According to a first variant, a second one a seal is further placed at the periphery of the third and second glass sheets to maintain the second space (for example 16mm thick), said second cavity being filled with less a gas. The gas may be, for example, air, argon, nitrogen, krypton, xenon, SF6, C0 2 , or any other thermal insulating gas. According to a second variant, the third and second glass sheets are assembled in a gastight manner (providing vacuum) via a seal placed at the periphery of the glass sheets closing the second cavity and a plurality of spacers according to the invention. The invention is sandwiched between the third and second glass sheets so as to maintain the second space between these glass sheets. This gives triple glazing under vacuum.
Bien entendu, d'autres variantes sont envisageables notamment en remplaçant une feuille de verre par un panneau de verre feuilleté ou par tout autre ajout ou modification. Of course, other variants can be envisaged, in particular by replacing a glass sheet with a laminated glass panel or by any other addition or modification.
Bien entendu, l'invention n'est pas limitée aux exemples de réalisation mentionnés ci-dessus. Of course, the invention is not limited to the embodiments mentioned above.
