Abstract

The unit consists of at least two panes of glass (1,2) with a spacer frame (3) between their edges. The spacer frame is hollow and made from a metal with a low thermal conductivity, e.g. stainless steel, with holes (5) round its inner surface, and is filled with a moisture-absorbing (7) material. Primary seals (8), e.g. of a butyl material, are fitted between the spacer frame and the glass panes. The inner faces of the glass panels have bevelled edges (10), and the opposite surfaces (12) of the spacer frame side walls slope inwards at a similar angle, forming triangular-section channels which are filled with an adhesive sealing material (9).

Description

La présente invention concerne un vitrage isolant à isolation thermique accrue dans les zones marginales du vitrage, comprenant au moins deux feuilles de verre et un cadre d'espacement métallique composé d'un profilé creux dont la section transversale va en se rétrécissant vers la périphérie du vitrage, les gorges formées par les surfaces inclinées du profilé creux et les zones de surfaces opposées des feuilles de verre étant remplies d'une matière d'étanchéité adhésive.The present invention relates to insulating insulating glazing increased thermal in the marginal areas of the glazing, including at minus two sheets of glass and a compound metal spacer a hollow profile whose cross section narrows towards the periphery of the glazing, the grooves formed by the inclined surfaces of the profile hollow and the opposite surface areas of the glass sheets being filled an adhesive sealant.

Dans le cas des vitrages isolants habituels, le cadre d'espacement est en règle générale composé d'un profilé creux en aluminium assemblé aux feuilles de verre grâce à des couches adhésives. Le cadre d'espacement est légèrement décalé des bords des feuilles de verre en direction de la surface de visibilité, de sorte qu'il se forme sur le bord entre la surface de pourtour du cadre d'espacement et les surfaces intérieures des deux feuilles de verre un espace creux qui est rempli d'une matière d'étanchéité adhésive durcissante. En raison de cette construction et de la conduction thermique accrue qui en résulte dans la zone marginale, l'effet d'isolation thermique du vitrage isolant au niveau du bord est nettement réduit par rapport à la surface de vitrage restante. Cela a pour conséquence que, dans le cas de basses températures extérieures, les vitrages isolants du côté orienté vers la pièce sont plus froids sur le bord que dans la zone centrale de sorte que les vitrages peuvent s'embuer au niveau du bord étant donné qu'à cet endroit l'humidité de l'air se condense sur ces zones marginales plus froides.In the case of usual insulating glazing, the spacing frame is generally composed of a hollow aluminum profile assembled to glass sheets with adhesive layers. The spacing frame is slightly offset from the edges of the glass sheets towards the surface of visibility, so that it forms on the edge between the perimeter surface of the spacer frame and the interior surfaces of the two glass sheets a hollow space which is filled with an adhesive sealant hardening. Due to this construction and thermal conduction resulting increase in the marginal zone, the thermal insulation effect insulating glass at the edge is significantly reduced compared to the remaining glazing area. This has the consequence that, in the case of low outside temperatures, the insulating glass on the side facing the piece are cooler on the edge than in the central area so the glazing may fog up at the edge since at this point the humidity of the air condenses on these colder marginal zones.

Afin de réduire cet effet, il est connu de fabriquer le cadre d'espacement en un métal de plus faible conductibilité thermique. Ainsi, les documents EP 0 403 058 A1 et WO 93/19274, par exemple, décrivent des vitrages isolants du type cité dans le cas desquels, pour augmenter l'effet d'isolation thermique dans la zone marginale, les cadres d'espacement sont formés de profilés creux à paroi mince en acier inoxydable présentant une plus faible conductibilité thermique que, par exemple, l'aluminium. En outre, il est connu de par ces documents de renoncer au remplissage de l'espace creux entre les deux feuilles de verre dans la zone à proximité immédiate du bord en dehors de la surface périphérique du cadre d'espacement afin de réduire ainsi la section transversale du corps intermédiaire responsable de la conduction thermique.In order to reduce this effect, it is known to manufacture the frame spacing in a metal of lower thermal conductivity. So the EP 0 403 058 A1 and WO 93/19274, for example, describe insulating glass of the type mentioned in the case of which, to increase the effect thermal insulation in the marginal area, the spacing frames are formed from thin-walled hollow sections of stainless steel with a lower thermal conductivity than, for example, aluminum. In Furthermore, it is known from these documents to give up the filling of the hollow space between the two sheets of glass in the nearby area immediately from the edge outside the peripheral surface of the frame spacing to reduce the cross section of the body intermediary responsible for thermal conduction.

En raison de la suppression de la matière d'étanchéité adhésive à l'extérieur du cadre d'espacement, la largeur des surfaces d'adhésion effectives entre le cadre d'espacement et les surfaces de verre diminue. Cela peut toutefois, dans certaines circonstances, entraíner un affaiblissement de l'assemblage collé et, à long terme, nuire à l'effet d'étanchéité. Il est certes possible d'y remédier en augmentant la hauteur du cadre d'espacement, mais le bord visible du vitrage isolant en sera ainsi plus large. Il est toutefois d'un intérêt majeur de maintenir le bord visible et donc la profondeur d'insertion du vitrage isolant dans le châssis aussi faibles que possible.Due to the removal of the adhesive sealing material from the outside of the spacing frame, the width of the adhesion surfaces between the spacing frame and the glass surfaces decreases. That may, however, in certain circumstances lead to a weakening of the bonded assembly and, in the long term, adversely affect the sealing effect. It is certainly possible to remedy it by increasing the height of the frame spacing, but the visible edge of the insulating glass will be more large. It is however of major interest to keep the edge visible and therefore the depth of insertion of the insulating glass in the frame as low as possible.

Actuellement, les systèmes d'étanchéité habituels pour des vitrages isolants comportent un moyen d'étanchéité primaire large d'environ 2 à 4 mm et fait de butyle et un moyen d'étanchéité secondaire s'y rattachant fait d'un autre système adhésif qui est injecté dans les gorges. Pour ce deuxième système adhésif, il est en principe connu et conforme aux instructions délivrées par le fabricant de matières adhésives de placer le cadre d'espacement entre les feuilles de verre aussi bien que possible vers l'intérieur de telle sorte que la largeur recouverte de colle sur le vitrage dépasse d'au moins 2 mm la largeur recouverte de colle sur le cadre d'espacement. De la sorte une adhérence suffisante de la colle au verre sera garantie. Dans le cas des vitrages isolants connus, cela signifie que le cadre d'espacement doit être décalé vers l'intérieur au moins dans une mesure telle que cette plus grande surface d'adhésion soit du côté du verre.Currently, the usual sealing systems for glazing insulators have a primary sealing medium of about 2 to 4 mm and made of butyl and a secondary sealing means attached thereto made of another adhesive system which is injected into the grooves. For this second adhesive system, it is in principle known and complies with instructions issued by the adhesive manufacturer to place the spacing frame between the glass sheets as well as possible towards the interior so that the width covered with glue on the glazing at least 2 mm more than the width covered with adhesive on the frame spacing. In this way sufficient adhesion of the glue to the glass will be guarantee. In the case of known insulating glazing, this means that the frame spacing should be shifted inward at least one measure such that this greater adhesion surface is on the side of the glass.

L'invention a pour but de concevoir un vitrage isolant du type mentionné dans le préambule de telle sorte que, même dans le cas d'une hauteur relativement faible du profilé d'espacement, il soit possible d'atteindre une étanchéité satisfaisante et durable du vitrage.The object of the invention is to design an insulating glazing of the type mentioned in the preamble so that even in the case of a relatively low height of the spacing profile, it is possible to achieve satisfactory and lasting sealing of the glazing.

Ce but est atteint, conformément à l'invention, par le fait que les vitrages sont chanfreinés au niveau de leurs bords sur les surfaces opposées aux surfaces inclinées du cadre d'espacement.This object is achieved, in accordance with the invention, by the fact that the glazings are chamfered at their edges on surfaces opposite the inclined surfaces of the spacer frame.

Grâce au chanfreinage conforme à l'invention des bords du vitrage, la surface d'adhésion sur les feuilles de verre est plus élargie de sorte qu'il est possible, de cette manière, d'atteindre les mêmes conditions d'adhérence que jusqu'à présent sur les feuilles de verre et de placer, par la même occasion, le cadre d'espacement davantage sur le bord, grâce à quoi le bord d'adhésion visible est réduit dans son ensemble et une plus faible profondeur d'insertion du vitrage isolant dans le châssis devient ainsi possible.Thanks to the chamfering according to the invention of the edges of the glazing, the adhesion surface on the glass sheets is more enlarged so that it is possible, in this way, to achieve the same adhesion conditions that so far on the glass sheets and place, by the same occasion the spacing frame more on the edge, whereby the edge visible adhesion is reduced as a whole and a lower depth of insertion of insulating glass in the frame thus becomes possible.

Un exemple de réalisation de l'invention sera décrit plus en détail ci-après avec référence au dessin annexé.An exemplary embodiment of the invention will be described in more detail below with reference to the accompanying drawing.

Le dessin est une vue en coupe de la zone marginale d'un vitrage isolant. Le vitrage isolant comporte les deux feuilles de verre 1 et 2 qui sont faites, respectivement, de verre flotté, par exemple, d'une épaisseur de 6 mm. Entre les deux feuilles de verre 1, 2 est placé au niveau du bord un cadre d'espacement 3 fait d'un profilé creux 4 dont l'intérieur creux est en communication par l'intermédiaire des orifices 5 avec l'espace d'air 6. L'intérieur creux du profilé creux 4 est rempli d'un tamis moléculaire ou d'un autre agent de déshydratation 7.The drawing is a sectional view of the marginal area of a glazing insulating. The insulating glazing comprises the two glass sheets 1 and 2 which are made of float glass, for example, of a thickness of 6 mm. Between the two glass sheets 1, 2 is placed at the edge a spacer frame 3 made of a hollow profile 4 whose hollow interior is in communication via the openings 5 with the air space 6. The hollow interior of the hollow profile 4 is filled with a molecular sieve or another dehydrating agent 7.

Un système d'étanchéité comprenant un moyen d'étanchéité primaire 8 et un moyen d'étanchéité secondaire 9 sert à assembler par collage le cadre d'espacement 3 et les deux feuilles de verre et à rendre le bord étanche. Le moyen d'étanchéité primaire 8 se compose d'une matière d'étanchéité de butyle, par exemple d'une largeur de 2 à 5 mm, disposée le long des bords du profilé creux 4 à proximité de l'espace d'air 6. Habituellement, le cadre d'espacement est d'abord revêtu des deux côtés d'un cordon de butyle et les deux feuilles de verre sont alors pressées contre le cadre d'espacement revêtu.A sealing system comprising a primary sealing means 8 and a secondary sealing means 9 is used to bond the spacer frame 3 and the two sheets of glass and to make the edge waterproof. The primary sealing means 8 consists of a material butyl sealant, for example with a width of 2 to 5 mm, arranged on along the edges of the hollow profile 4 near the air space 6. Usually the spacer frame is first coated on both sides of a butyl bead and the two glass sheets are then pressed against the coated spacing frame.

Le profilé creux 4 formant le cadre d'espacement 3 présente une section transversale telle que les parois latérales collées aux feuilles de verre forment, dans la partie proche de l'espace d'air, un angle droit avec la paroi 11 limitant l'espace d'air. Sur cette partie, les parois latérales sont pourvues du moyen d'étanchéité primaire. Les parties des parois latérales du profilé creux 4 qui s'y rattachent sont inclinées vers l'intérieur de telle sorte que la section transversale du profilé creux 4 aille en se rétrécissant vers l'extérieur. Ces surfaces inclinées 12 représentent les surfaces d'adhésion du cadre d'espacement pour le moyen d'étanchéité secondaire et forment, avec les zones marginales opposées des feuilles de verre, des gorges dans lesquelles est injectée la matière d'étanchéité du moyen d'étanchéité secondaire 9.The hollow profile 4 forming the spacer frame 3 has a cross section such as the side walls glued to the glass sheets form, in the part close to the air space, a right angle with the wall 11 limiting the air space. On this part, the side walls are provided of the primary sealing means. The parts of the side walls of the profile hollows 4 attached thereto are inclined inward so that the cross section of hollow section 4 tapers towards outside. These inclined surfaces 12 represent the adhesion surfaces of the spacer frame for the secondary sealing means and form, with the opposite marginal areas of the glass sheets, grooves in which is injected the sealing material of the sealing means secondary 9.

Dans le cas représenté, les feuilles de verre 1 et 2 sont chanfreinées le long de leur périphérie d'un angle a d'environ 30°. Ce chanfreinage a pour conséquence que la largeur B des surfaces marginales inclinées 10 disponibles pour le moyen d'étanchéité secondaire est agrandie de 40 %. Il est ainsi également possible d'atteindre une étanchéité et un collage suffisants même lorsque la matière d'étanchéité adhésive n'est injectée que dans les deux gorges entre les parois latérales inclinées 12 du profilé creux et les surfaces chanfreinées 10 des feuilles de verre. Le côté extérieur 13 peut être exempt de matière d'étanchéité adhésive. Si le profilé creux 4 présente en outre une mince épaisseur de paroi et est fait d'un métal de faible conductibilité thermique, des vitrages isolants présentant un effet d'isolation thermique particulièrement bon dans la zone marginale et par la même occasion un bord relativement étroit, peuvent de cette façon être fabriqués.In the case shown, the glass sheets 1 and 2 are chamfered on along their periphery at an angle a of about 30 °. This chamfering has for consequence that the width B of the inclined marginal surfaces 10 available for the secondary sealing medium is enlarged by 40%. he is also possible to achieve sealing and bonding sufficient even when the adhesive sealing material is only injected in the two grooves between the inclined side walls 12 of the hollow profile and the chamfered surfaces 10 of the glass sheets. The outer side 13 may be free of adhesive sealant. If the hollow profile 4 furthermore has a thin wall thickness and is made of a metal of low thermal conductivity, insulating glazing having an effect particularly good thermal insulation in the marginal area and by the same occasion a relatively narrow edge, can in this way be manufactured.
