Description

Vitrage isolant et son procédé de fabrication Insulating glass and its manufacturing process
L'invention a pour objet un vitrage isolant et son procédé de fabrication.The invention relates to insulating glazing and its manufacturing process.
Un type de vitrage isolant bien connu comporte deux feuilles de verre qui sont espacées par une lame de gaz tel que de l'air et, qui sont écartées et réunies au moyen d'un cadre entretoise constitué par des profilés métalliques creux plies ou assemblés par des pièces d'angle. Les profilés sont garnis d'un tamis moléculaire qui a notamment pour rôle d'absorber les molécules d'eau emprisonnées dans la lame d'air intercalaire au moment de la fabrication du vitrage et qui seraient susceptibles de se condenser par temps froid, entraînant l'apparition de buée.A well-known type of insulating glazing comprises two sheets of glass which are spaced apart by a blade of gas such as air and which are separated and joined by means of a spacer frame formed by hollow metal profiles folded or assembled by corner pieces. The profiles are lined with a molecular sieve which has the role, in particular, of absorbing the water molecules trapped in the interlayer of air at the time of the manufacture of the glazing and which would be liable to condense in cold weather, causing the appearance of fogging.
Pour assurer l'étanchéité du vitrage, le cadre entretoise est collé aux feuilles de verre par un cordon élastomère du type caoutchouc butyl appliqué directement sur les profilés par extrusion au travers d'une buse. Chaque coin du cadre entretoise est également garni au niveau de la pièce d'angle par du caoutchouc butyl. Une fois le vitrage assemblé, le cordon élastomère d'étanchéité joue un rôle de maintien mécanique provisoire des feuilles de verre. Enfin, on injecte dans la gorge périphérique délimitée par les deux feuilles de verre et le cadre entretoise un mastic d'étanchéité réticulable du type polysulfure ou polyurethane qui termine l'assemblage mécanique des feuilles de verre. Le caoutchouc butyl a principalement comme rôle de rendre étanche l'intérieur du vitrage à la vapeur d'eau, tandis que le mastic assure une étanchéité à l'eau liquide ou aux solvants.To seal the glazing, the spacer frame is glued to the glass sheets by an elastomeric cord of the butyl rubber type applied directly to the profiles by extrusion through a nozzle. Each corner of the spacer frame is also lined at the corner piece with butyl rubber. Once the glazing has been assembled, the elastomeric sealing bead acts as a temporary mechanical support for the glass sheets. Finally, a crosslinkable sealing mastic of the polysulfide or polyurethane type is injected into the peripheral groove delimited by the two glass sheets and the spacer frame, which completes the mechanical assembly of the glass sheets. The main role of butyl rubber is to seal the interior of the glazing with water vapor, while the sealant provides sealing against liquid water or solvents.
La fabrication de ce vitrage nécessite plusieurs matériaux distincts dont les profilés, les pièces d'angle, le tamis moléculaire, les joints organiques d'étanchéité, ces matériaux n'étant pas assemblés en une seule et même opération.The manufacture of this glazing requires several separate materials including profiles, corner pieces, molecular sieve, organic seals, these materials are not assembled in one and the same operation.
Un inconvénient posé par une telle fabrication est celui du stockage des matériaux. Afin d'être opérationnel pour toute nouvelle commande passée pour des vitrage isolants, de nombreux lots de chaque matériaux doivent être à disposition, ce qui ne participe pas à une gestion simple et rapide quant à l'approvisionnement et au stockage de ces matériaux.A drawback posed by such manufacture is that of the storage of materials. In order to be operational for any new order placed for insulating glazing, numerous batches of each material must be available, which does not contribute to simple and rapid management as regards the supply and storage of these materials.
En outre, le nombre actuel de matériaux à assembler engendre plusieurs opérations de montage qui, bien qu'automatisées, sont réalisées les unes après les autres ce qui pénalise notablement le temps de fabrication. Certaines de ces opérations imposent aussi des interruptions dans la chaîne de fabrication, pouvant par ces courts temps morts gêner davantage la cadence de production.In addition, the current number of materials to be assembled generates several assembly operations which, although automated, are carried out one after the other. the others which significantly penalizes the manufacturing time. Some of these operations also impose interruptions in the production line, which can by these short dead times further hamper the production rate.
L'invention a donc pour objet d'obvier à ces inconvénients en proposant un vitrage isolant dont le choix des matériaux permet de faciliter la gestion de leur flux de fabrication et de simplifier les opérations de montage.The object of the invention is therefore to obviate these drawbacks by proposing an insulating glazing whose choice of materials makes it possible to facilitate the management of their manufacturing flow and to simplify the mounting operations.
Selon l'invention, le vitrage isolant qui comporte, au moins deux feuilles de verre espacées par une lame de gaz, un intercalaire servant à espacer les deux feuilles de verre et présentant une face interne en regard de la lame de gaz et une face externe opposée, ainsi que des moyens d'étanchéité vis-à-vis de l'intérieur dudit vitrage, est caractérisé en ce que l'intercalaire se présente sous la forme d'un profilé sensiblement plat qui ceinture le pourtour du vitrage en étant plaqué par sa face interne contre les tranches des feuilles de verre, et maintenu fixé par des moyens de solidarisation. Ce type de profilé et sa disposition sur les tranches du vitrage présentent notamment l'avantage d'augmenter la visibilité au travers du vitrage puisque l'intercalaire n'est plus visible en périphérie.According to the invention, the insulating glazing which comprises, at least two sheets of glass spaced apart by a gas slide, an interlayer serving to space the two sheets of glass and having an internal face opposite the gas slide and an external face opposite, as well as sealing means vis-à-vis the interior of said glazing, is characterized in that the interlayer is in the form of a substantially flat profile which surrounds the periphery of the glazing by being pressed by its internal face against the edges of the glass sheets, and kept fixed by securing means. This type of profile and its arrangement on the edges of the glazing have in particular the advantage of increasing visibility through the glazing since the interlayer is no longer visible at the periphery.
Selon une caractéristique, les moyens d'étanchéité du vitrage, qui présentent des propriétés d'étanchéité aux gaz, poussières et à l'eau liquide, sont disposés au moins sur la face externe de l'intercalaire. Ces moyens d'étanchéité sont constitués par un revêtement métallique, de préférence en inox ou en aluminium, qui présente une épaisseur comprise entre 2 et 50 μm.According to one characteristic, the sealing means of the glazing, which have sealing properties against gases, dust and liquid water, are arranged at least on the external face of the interlayer. These sealing means consist of a metallic coating, preferably made of stainless steel or aluminum, which has a thickness of between 2 and 50 μm.
Selon une mode de réalisation préférentiel de l'intercalaire, celui-ci est à base de matière thermoplastique armée ou non de fibres de renforcement telles que des fibres de verre coupées ou continues.According to a preferred embodiment of the interlayer, it is based on thermoplastic material reinforced or not with reinforcing fibers such as cut or continuous glass fibers.
Selon une caractéristique, l'intercalaire présente une résistance linéique au flambage d'au moins 400 N/m. Afin d'assurer cette résistance, l'intercalaire doit présenter une épaisseur d'au moins 0,1 mm lorsqu'il est constitué entièrement d'inox, d'au moins 0,15 mm lorsqu'il est entièrement en aluminium, et d'au moins 0,25 mm lorsqu'il est en matière thermoplastique armé de fibres de renforcement.According to one characteristic, the interlayer has a linear buckling resistance of at least 400 N / m. To ensure this resistance, the interlayer must have a thickness of at least 0.1 mm when it is made entirely of stainless steel, of at least 0.15 mm when it is made entirely of aluminum, and d '' at least 0.25 mm when made of thermoplastic material reinforced with reinforcing fibers.
Avantageusement, les moyens de solidarisation de l'intercalaire contre le vitrage sont imperméables à l'eau, ils sont constitués par un adhésif du type colle qui résiste à des contraintes à l'arrachement d'au moins 0,45 Mpa. Selon une autre caractéristique, les extrémités libres de l'intercalaire sont assemblées pour ceinturer la totalité du vitrage de façon que l'une des extrémités recouvre l'autre, des moyens d'étanchéité complémentaires étant prévus pour obturer des sections latérales rendues ouvertes par le recouvrement. En variante, afin de ceinturer la totalité du vitrage, les extrémités libres de l'intercalaire présentent des formes complémentaires adaptées à coopérer mutuellement pour réaliser leur assemblage selon un aboutement. Un ruban adhésif ou de la colle étanche aux gaz et à la vapeur d'eau sera de préférence appliqué sur la zone d'aboutement. Le procédé de fabrication de l'invention est caractérisé en ce que :Advantageously, the means for securing the interlayer against the glazing are impermeable to water, they are constituted by an adhesive of the glue type which withstands tear stresses of at least 0.45 Mpa. According to another characteristic, the free ends of the interlayer are assembled to surround the whole of the glazing so that one of the ends covers the other, complementary sealing means being provided for closing the lateral sections made open by the recovery. As a variant, in order to surround the entire glazing, the free ends of the interlayer have complementary shapes adapted to cooperate with each other in order to assemble them according to a connection. An adhesive tape or glue that is gas- and vapor-tight will preferably be applied to the abutment area. The manufacturing process of the invention is characterized in that:
- on maintient les deux feuilles de verre parallèles et espacées ;the two sheets of glass are kept parallel and spaced apart;
- on met en place la face interne de l'intercalaire pourvu des moyens de solidarisation contre les tranches des feuilles de verre sur la totalité du pourtour du vitrage ; - on applique quasi-instantanément lors de la mise en place de l'intercalaire des moyens de pression sur la face externe de l'intercalaire de façon à assurer l'adhésion de l'intercalaire avec les tranches des feuilles de verre; et- the inner face of the interlayer is fitted with means for securing against the edges of the glass sheets over the entire periphery of the glazing; - Is applied almost instantly during the establishment of the interlayer pressure means on the outer face of the interlayer so as to ensure the adhesion of the interlayer with the edges of the glass sheets; and
- après ceinturage de la totalité du vitrage on assemble solidairement les deux extrémités de l'intercalaire. Selon une caractéristique, l'intercalaire se présente avant sa mise en place sous la forme d'un ruban bobiné qui est destiné à être déroulé, étiré et coupé à la longueur correspondant sensiblement au périmètre du vitrage, tandis que les moyens de solidarisation du type colle sont déposés sur le ruban en etirement par des moyens d'injection. Avantageusement, le desséchant est déposé sur le ruban en etirement lors de l'application des moyens de solidarisation.- after surrounding the entire glazing, the two ends of the interlayer are joined together. According to one characteristic, the interlayer is presented before its installation in the form of a wound ribbon which is intended to be unrolled, stretched and cut to the length corresponding substantially to the perimeter of the glazing, while the securing means of the type glue are deposited on the stretched tape by injection means. Advantageously, the desiccant is deposited on the stretching tape during the application of the joining means.
Selon une autre caractéristique, la mise en place de l'intercalaire s'effectue en l'appliquant par compression en un point d'amorçage et contre les tranches d'un premier côté du vitrage, le ceinturage s'effectuant à partir de ce point d'amorçage et la mise en place du ruban sur les angles du vitrage étant réalisée en chauffant préalablement la face externe de l'intercalaire afin d'aider à son pliage autour des angles et d'épouser parfaitement leur contour.According to another characteristic, the insertion of the interlayer is carried out by applying it by compression at a starting point and against the edges of a first side of the glazing, the belting being effected from this point priming and the establishment of the ribbon on the corners of the glazing being carried out by previously heating the external face of the interlayer in order to assist in its folding around the angles and to conform perfectly to their outline.
De préférence, le point d'amorçage est situé en un milieu de côté du vitrage de façon à appliquer et comprimer l'intercalaire simultanément dans deux directions opposées pour ceinturer le pourtour du vitrage selon deux moitiés de périmètre, ce qui permet de gagner en temps de fabrication.Preferably, the priming point is located in the middle of the side of the glazing so as to apply and compress the interlayer simultaneously in two opposite directions to surround the perimeter of the glazing in two halves of the perimeter, which saves manufacturing time.
En variante, le point d'amorçage peut être situé plutôt au niveau d'un angle du vitrage. Dans une variante de réalisation du ceinturage du vitrage, la mise en place de l'intercalaire s'effectue en appliquant deux rubans par compression en deux points d'amorçage à l'aide de moyens de distribution et de compression, et le ceinturage s'effectue à partir de ces points d'amorçage par des mouvements de translation du vitrage et/ou des moyens de distribution. Cette variante permet très avantageusement, combinée avec le profilé de l'invention, de fournir un vitrage présentant une forme complexe, en particulier avec des parties courbes.Alternatively, the starting point may be located rather at a corner of the glazing. In an alternative embodiment of the glazing belt, the insertion of the interlayer is carried out by applying two ribbons by compression at two priming points using distribution and compression means, and the belt s' performs from these starting points by translational movements of the glazing and / or distribution means. This variant makes it very advantageous, combined with the profile of the invention, to provide glazing having a complex shape, in particular with curved parts.
De manière pratique, toutes les opérations de fabrication du vitrage peuvent être réalisées dans une chambre remplie du gaz devant être contenu dans le vitrage. Toutefois en variante, il est possible d'envisager un dispositif d'alimentation en gaz qui est inséré entre les deux feuilles de verre pour délivrer du gaz tandis que le ceinturage du vitrage est effectué, et qui est retiré juste avaηt la fin du ceinturage.In practice, all the glazing manufacturing operations can be carried out in a chamber filled with the gas to be contained in the glazing. However as a variant, it is possible to envisage a gas supply device which is inserted between the two sheets of glass to deliver gas while the glazing is being belted, and which is removed just before the belt is finished.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit et en regard des dessins annexés sur lesquels : - la figure 1 est une vue en coupe d'un vitrage isolant selon l'invention ; la figure 2 illustre une vue schématique en élévation du dispositif de fabrication du vitrage ; la figure 3 représente la figure 2 au cours d'une étape du procédé de fabrication ; la figure 4 est une vue agrandie de l'assemblage des deux extrémités libres de l'intercalaire de l'invention après ceinturage complet du vitrage; les figures 5a à 5c illustrent une variante de réalisation du ceinturage du vitrage.Other characteristics and advantages of the invention will appear on reading the description which follows and with reference to the appended drawings in which: - Figure 1 is a sectional view of an insulating glazing according to the invention; FIG. 2 illustrates a schematic elevation view of the device for manufacturing the glazing; Figure 3 shows Figure 2 during a step of the manufacturing process; Figure 4 is an enlarged view of the assembly of the two free ends of the interlayer of the invention after complete surround of the glazing; Figures 5a to 5c illustrate an alternative embodiment of the glazing belt.
La figure 1 illustre un vitrage isolant simple 1 obtenu par un procédé de fabrication qui sera décrit plus loin en regard de son dispositif visible à la figure 2. Le vitrage 1 comporte deux feuilles de verre 10 et 11 espacées par une lame de gaz 12, un intercalaire 2 qui sert à espacer les deux feuilles de verre et a pour rôle d'assurer le maintien mécanique de l'ensemble du vitrage, ainsi que des moyens d'étanchéité 3 destinés à rendre étanche le vitrage à l'eau liquide, aux solvants et à la vapeur d'eau.FIG. 1 illustrates a simple insulating glazing 1 obtained by a manufacturing process which will be described below with regard to its device visible in FIG. 2. The glazing 1 comprises two sheets of glass 10 and 11 spaced apart by a gas blade 12, a spacer 2 which is used to space the two sheets of glass and has for the role of ensuring the mechanical maintenance of the whole of the glazing, as well as of sealing means 3 intended to make the glazing waterproof to liquid water, to solvents and to water vapor.
L'intercalaire 2 se présente sous la forme d'un profilé sensiblement plat d'environ 1 mm d'épaisseur et de section sensiblement parallélipédique. Ce profilé a avantageusement une faible inertie mécanique, c'est-à-dire qu'il peut être aisément enroulé en présentant un faible rayon d'enroulement de 10 cm par exemple.The interlayer 2 is in the form of a substantially flat profile about 1 mm thick and of substantially parallelepiped section. This profile advantageously has a low mechanical inertia, that is to say that it can be easily wound by having a small winding radius of 10 cm for example.
Le profilé entoure le pourtour du vitrage. Il est disposé à la manière d'un ruban sur les tranches 10a et 11a des feuilles de verre et garantit l'assemblage mécanique du vitrage grâce à des moyens de solidarisation 4 qui assurent sa totale adhésion au verre.The profile surrounds the periphery of the glazing. It is arranged in the manner of a ribbon on the edges 10a and 11a of the glass sheets and guarantees the mechanical assembly of the glazing by means of fastening means 4 which ensure its total adhesion to the glass.
Le profilé est suffisamment rigide pour réaliser la fonction de maintien mécanique des deux feuilles de verre espacées. Sa rigidité est définie par la nature même de son matériau constitutif, dont la résistance linéique au flambage doit être au moins de 400 N/m.The profile is rigid enough to perform the mechanical holding function of the two spaced glass sheets. Its rigidity is defined by the very nature of its constituent material, the linear buckling resistance of which must be at least 400 N / m.
Par ailleurs, la nature du matériau dudit profilé est également choisie de façon qu'au cours du procédé de fabrication du vitrage, le profilé puisse présenter suffisamment de souplesse pour que soit effectué l'opération de ceinturage des tranches de verre, en particulier lors du bordage des angles.Furthermore, the nature of the material of said profile is also chosen so that during the glazing manufacturing process, the profile can have sufficient flexibility for the operation of belting of the glass slices, in particular during the planking angles.
Dans un premier mode de réalisation, l'intercalaire est entièrement métallique, le matériau choisi étant préférentiellement de l'inox ou bien de l'aluminium. Au cours du procédé, le bordage des angles est effectué par pliage à l'aide de machines bien connues de l'homme de l'art spécialisé dans la transformation de matériaux métalliques.In a first embodiment, the interlayer is entirely metallic, the material chosen preferably being stainless steel or else aluminum. During the process, the planking of the angles is carried out by folding using machines well known to those skilled in the art specialized in the transformation of metallic materials.
De manière à garantir une résistance linéique au flambage minimale de 400N/m, l'intercalaire devra présenter une épaisseur d'au moins 0,1 mm pour de l'inox, et de 0,15 mm pour de l'aluminium.In order to guarantee a minimum linear buckling resistance of 400N / m, the interlayer must have a thickness of at least 0.1 mm for stainless steel, and 0.15 mm for aluminum.
Dans un second mode de réalisation et préférentiel de l'invention, l'intercalaire 2 est à base de matière plastique armée ou non de fibres de renforcement coupées ou continues. Ainsi, un matériau peut être du styrène acrylonitrile (SAN) associé à des fibres de verre coupées, commercialisé par exemple sous le nom LURAN→ par la société BASF, ou bien du polypropylène armé de fibres de verre continues, vendu sous le nom TWINTEX→ par la société VETROTEX.In a second and preferred embodiment of the invention, the interlayer 2 is based on plastic material reinforced or not with cut or continuous reinforcing fibers. Thus, a material can be acrylonitrile styrene (SAN) associated with cut glass fibers, marketed for example under the name LURAN → by the company BASF, or else polypropylene. reinforced with continuous glass fibers, sold under the name TWINTEX → by the company VETROTEX.
Notons que dans le cas d'un matériau plastique qui est thermofusible, le bordage des angles du vitrage opéré par pliage après ramollissement de la matière, est effectué plus aisément qu'avec un matériau entièrement métallique. Par ailleurs, avec l'utilisation de matière plastique, il peut très avantageusement être prévu d'intégrer intrinsèquement, en partie ou en totalité, le desséchant au profilé, ce qui est impossible avec du métal. Le desséchant peut être un tamis moléculaire tel que de la zéolithe en poudre, dont la proportion peut atteindre jusqu'à 20% en masse ou environ 10% en volume. La quantité du desséchant est fonction de la durée de vie que l'on veut attribuer au vitrage.Note that in the case of a plastic material which is hot-melt, the planking of the angles of the glazing operated by folding after softening of the material, is carried out more easily than with an entirely metallic material. Furthermore, with the use of plastic, it can very advantageously be provided to integrate intrinsically, in part or in whole, the desiccant in the profile, which is impossible with metal. The desiccant can be a molecular sieve such as powdered zeolite, the proportion of which can reach up to 20% by mass or approximately 10% by volume. The quantity of the desiccant depends on the lifespan that we want to assign to the glazing.
Enfin, la matière plastique étant bien moins conductrice de chaleur que le métal, l'isolation thermique de l'ensemble du vitrage n'en est que meilleure lorsque le vitrage est par exemple exposé à un fort ensoleillement. Quant à l'addition de fibres de verre à la matière plastique, il en résulte un coefficient de dilatation thermique du matériau qui est bien plus faible que celui d'un plastique pur et qui devient proche du coefficient du verre, ce qui engendre, lors d'une variation thermique de la lame de gaz, une force de cisaillement moindre sur les moyens de solidarisation 4. Afin d'assurer une résistance linéique de 400 N/m, l'intercalaire 2 présente une épaisseur d'au moins 0,25 mm lorsqu'il est constitué de matière thermoplastique et de fibres de renforcement.Finally, since the plastic material is much less conductive of heat than metal, the thermal insulation of the whole of the glazing is only better when the glazing is for example exposed to strong sunlight. As for the addition of glass fibers to the plastic, this results in a coefficient of thermal expansion of the material which is much lower than that of a pure plastic and which becomes close to the coefficient of glass, which generates, during thermal variation of the gas slide, less shear force on the securing means 4. In order to ensure a linear resistance of 400 N / m, the interlayer 2 has a thickness of at least 0.25 mm when made of thermoplastic material and reinforcing fibers.
La largeur de l'intercalaire 2 est adaptée à l'épaisseur totale du vitrage qui peut être multiple en comprenant plusieurs feuilles de verre espacées par des lames de gaz. Avantageusement, l'intercalaire de l'invention ne nécessite la connaissance que de la largeur totale du vitrage et non des distances de séparation des feuilles de verre. En effet, les distances de séparation pour un vitrage multiple peuvent varier, ce qui entraîne nécessairement dans le cas de l'utilisation d'intercalaires conformes à ceux de l'état de la technique d'avoir à disposition pour la fabrication du vitrage plusieurs intercalaires pour les différentes séparations, et différentes largeurs d'intercalaires selon les distances de séparation.The width of the interlayer 2 is adapted to the total thickness of the glazing which can be multiple by comprising several sheets of glass spaced apart by gas blades. Advantageously, the interlayer of the invention requires knowledge only of the total width of the glazing and not of the separation distances of the glass sheets. Indeed, the separation distances for multiple glazing may vary, which necessarily means, in the case of the use of dividers in accordance with those of the state of the art, to have available for the manufacture of glazing several dividers for the different separations, and different widths of dividers according to the separation distances.
Pour tout vitrage, il convient donc simplement de disposer selon l'invention d'un intercalaire ou profilé d'une seule largeur correspondant à celle totale du vitrage quelles que soient le nombre de séparations isolantes internes de ce vitrage et la largeur de ces séparations.For all glazing, it is therefore simply necessary to have, according to the invention, an interlayer or profile with a single width corresponding to that of the glazing whatever the number of internal insulating partitions of this glazing and the width of these partitions.
Selon l'invention, l'intercalaire ou le profilé 2 comprend une face interne 20 et une face externe opposée 21 , la face interne 20 étant destinée à être plaquée, et maintenue, par ses bords dans le cas d'un vitrage isolant simple, contre les tranches 10a et 11 a des feuilles de verre grâce aux moyens de solidarisation 4.According to the invention, the interlayer or the profile 2 comprises an internal face 20 and an opposite external face 21, the internal face 20 being intended to be pressed, and held, by its edges in the case of a simple insulating glazing, against the edges 10a and 11 has glass sheets thanks to the securing means 4.
La face interne 20 du profilé possède dans sa partie centrale 22 et en regard avec la lame de gaz 12 les propriétés de celles d'un desséchant qui a pour but d'absorber les molécules d'eau qui peuvent être emprisonnées dans la lame de gaz. Ces propriétés de desséchant peuvent résulter de la nature du matériau de l'intercalaire, dont la composition même intègre un tamis moléculaire. En variante, l'élément desséchant sera plutôt obtenu par un dépôt de tamis moléculaire sur la partie centrale 22 avant la mise en place de l'intercalaire sur les tranches du vitrage, comme nous le verrons dans la suite de la description. Les bords de la face interne 20 sont recouverts d'un adhésif qui constitue les moyens de solidarisation 4.The internal face 20 of the profile has in its central part 22 and facing the gas plate 12 the properties of those of a desiccant which aims to absorb the water molecules which can be trapped in the gas plate . These desiccant properties can result from the nature of the interlayer material, the very composition of which incorporates a molecular sieve. As a variant, the drying element will rather be obtained by depositing a molecular sieve on the central part 22 before the insertion of the interlayer on the edges of the glazing, as we will see in the following description. The edges of the internal face 20 are covered with an adhesive which constitutes the joining means 4.
L'adhésif est du type colle; il est étanche aux gaz, à la vapeur d'eau. Des essais effectués conformément à la norme américaine ASTM 96-63T sur des échantillons de colle de 1 ,5 mm d'épaisseur ont montré qu'une colle présentantun coefficient de perméabilité à la vapeur d'eau de 35 g/24h.m2 tel que celui du silicone convient. Bien entendu, une colle ayant un coefficient de perméabilité de 4 g/24h.m2 comme le polyurethane, ou même inférieur, convient davantage car l'étanchéité étant encore améliorée, une quantité moins importante de desséchant est alors à prévoir. L'adhésif doit également résister au décollage par l'eau liquide, par les ultra-violets ainsi que par les tractions pouvant être exercées perpendiculairement aux faces du vitrage et nommées couramment contraintes au cisaillement, et par les tractions exercées parallèlement à la force du poids du vitrage. Une colle satisfaisante doit résister à des contraintes à l'arrachement d'au moins 0,45 MPa. De préférence, l'adhésif présente des propriétés de collage rapide, de l'ordre de quelques secondes; il s'agit d'un adhésif dont la prise s'effectue par réaction chimique, activée ou non par de la chaleur ou par une pression, ou bien s'effectue par refroidissement si l'adhésif est constitué d'une matière thermofusible du type hot-melt, par exemple à base de polyurethane réticulable avec l'humidité de l'air.The adhesive is of the glue type; it is impermeable to gases and water vapor. Tests carried out in accordance with the American standard ASTM 96-63T on samples of adhesive 1.5 mm thick have shown that an adhesive having a coefficient of permeability to water vapor of 35 g / 24h.m 2 such that silicone is suitable. Of course, an adhesive having a permeability coefficient of 4 g / 24h.m 2 like polyurethane, or even lower, is more suitable because the seal being further improved, a lesser amount of desiccant is then to be expected. The adhesive must also resist takeoff by liquid water, by ultraviolet rays as well as by the pulls which can be exerted perpendicular to the faces of the glazing and commonly called shear stresses, and by the pulls exerted parallel to the force of the weight. glazing. A satisfactory adhesive must withstand peel stresses of at least 0.45 MPa. Preferably, the adhesive has fast bonding properties, of the order of a few seconds; it is an adhesive which sets by chemical reaction, activated or not by heat or by pressure, or else is carried out by cooling if the adhesive is made of a material hot-melt of the hot-melt type, for example based on polyurethane crosslinkable with air humidity.
La face externe 21 de l'intercalaire en matière plastique renforcée est recouverte d'un revêtement de protection métallique 21 a du type feuillard en aluminium ou en inox présentant une épaisseur comprise entre 2 et 50 μm, ce revêtement constituant les moyens d'étanchéité 3. Outre son rôle d'étanchéité, le feuillard, en particulier lorsqu'il est en inox, protège efficacement le profilé contre l'abrasion, par exemple lors de sa manutention ou de son transport. Enfin, il favorise l'échange de chaleur avec la matière thermoplastique lorsqu'il s'agit de ramollir cette dernière pendant le procédé de fabrication.The outer face 21 of the reinforced plastic interlayer is covered with a metallic protective coating 21 a of the strip type of aluminum or stainless steel having a thickness of between 2 and 50 μm, this coating constituting the sealing means 3 In addition to its sealing role, the strip, in particular when it is made of stainless steel, effectively protects the profile against abrasion, for example during its handling or transport. Finally, it promotes heat exchange with the thermoplastic when it comes to softening the latter during the manufacturing process.
En variante, le revêtement métallique 21a pourrait être suffisamment large pour recouvrir la face externe 21 et être rabattu sur les bords de la face interne 20.As a variant, the metal covering 21a could be wide enough to cover the external face 21 and be folded over the edges of the internal face 20.
Les chiffres donnés plus haut sur l'épaisseur de l'intercalaire selon la nature du matériau utilisé sont fournis pour une résistance au flambage de 400 N/m linéaire, qui est une valeur classique pour les vitrages de dimensions les plus courants, à savoir 1 ,20 m par 0,50 m. Toutefois, pour élargir l'utilisation à des vitrages de dimensions plus importantes et/ou vitrages soumis à des conditions extrêmes de sollicitation, on préférera concevoir des vitrages dont l'intercalaire est apte à résister à une force de 5700 N par mètre linéaire. Afin de parvenir à une telle résistance au flambage, nous donnons ci-après un tableau indiquant le coefficient de sécurité établi par rapport à la référence de 5700 N/m en fonction des épaisseurs correspondantes à donner à l'intercalaire de l'invention selon le type de matériau.The figures given above on the thickness of the interlayer according to the nature of the material used are provided for a buckling resistance of 400 N / linear m, which is a conventional value for glazing of the most common dimensions, namely 1 , 20 m by 0.50 m. However, to widen the use to glazings of larger dimensions and / or glazings subjected to extreme conditions of stress, it will be preferred to design glazings whose interlayer is able to withstand a force of 5700 N per linear meter. In order to achieve such buckling resistance, we give below a table indicating the safety coefficient established with respect to the reference of 5700 N / m as a function of the corresponding thicknesses to be given to the interlayer of the invention according to the type of material.
Le procédé de fabrication va à présent être décrit en s'attachant au mode de réalisation préférentiel de l'invention utilisant un intercalaire à base de matière thermoplastique renforcée. Les feuilles de verre 10 et 11 sont acheminées sur chant par des moyens usuels jusqu'à une chambre pouvant enfermer le gaz à introduire dans le vitrage.The manufacturing process will now be described by focusing on the preferred embodiment of the invention using a spacer based on reinforced thermoplastic material. The glass sheets 10 and 11 are conveyed on edge by usual means to a chamber capable of enclosing the gas to be introduced into the glazing.
Les feuilles de verre 10 et 11 sont maintenues à l'écartement désiré au moyen de ventouses disposées sur les faces externes du vitrage et contrôlées par des vérins pneumatiques.The glass sheets 10 and 11 are maintained at the desired spacing by means of suction cups arranged on the external faces of the glazing and controlled by pneumatic cylinders.
La figure 2 illustre schématiquement le dispositif de fabrication du vitrage enfermé dans la chambre C.FIG. 2 schematically illustrates the device for manufacturing the glazing enclosed in chamber C.
Une bobine 50 constitue le magasin du profilé 2 qui est déroulé et étiré, à l'aide d'un dispositif d'étirement non visible, sous forme d'un ruban qui est coupé à une longueur équivalente au périmètre du vitrage, la largeur du ruban correspondant à l'épaisseur totale du vitrage.A reel 50 constitutes the magazine of the profile 2 which is unrolled and stretched, using a non-visible stretching device, in the form of a ribbon which is cut to a length equivalent to the perimeter of the glazing, the width of the ribbon corresponding to the total thickness of the glazing.
Dès la mise à plat du profilé est déposé l'adhésif 4 à l'aide de moyens d'injection 51 , tels qu'une buse, sur la face interne 20 du ruban destinée a être appliquée sur la tranche du vitrage. Dans ce cas, le ruban comprend le desséchant de manière inhérente à sa face interne, le desséchant ayant été incorporé sous forme de poudre ou de granulés à la matière thermoplastique renforcée lors de la fabrication du profilé.As soon as the profile is laid flat, the adhesive 4 is deposited using injection means 51, such as a nozzle, on the internal face 20 of the tape intended to be applied to the edge of the glazing. In this case, the strip comprises the desiccant inherently on its internal face, the desiccant having been incorporated in the form of powder or granules in the reinforced thermoplastic material during the manufacture of the profile.
Toutefois, lorsqu'il s'agit d'ajouter le desséchant ultérieurement à la fabrication du profilé, on préférera mettre en place le desséchant et l'adhésif au cours d'une seule et même opération à l'aide de trois buses d'injection, deux buses latérales visant les bords du ruban pour le dépôt de l'adhésif dans le but d'être en regard des tranches du vitrage et une buse centrale injectant le desséchant sur la partie centrale 22 du ruban dans le but d'être en vis-à-vis de la lame de gaz. II est aussi possible d'envisager un adhésif qui a été déposé lors de la fabrication du profilé et qui est protégé jusqu'à son utilisation, correspondant ici jusqu'àà l'application du profilé contre le vitrage.However, when it is a question of adding the desiccant later to the manufacture of the profile, it will be preferable to put the desiccant and the adhesive in place in a single operation using three injection nozzles. , two side nozzles aiming at the edges of the tape for depositing the adhesive in order to be opposite the glazing edges and a central nozzle injecting the desiccant on the central part 22 of the tape in order to be in screw opposite the gas slide. It is also possible to envisage an adhesive which was deposited during the manufacture of the profile and which is protected until its use, corresponding here until the application of the profile against the glazing.
Au moins un galet presseur 54 contrôlé par un bras articulé non illustré effectue l'application et la compression du ruban 2 contre la tranche du vitrage 1 sur l'ensemble de son périmètre. Pour un gain de temps dans l'opération de ceinturage, il sera de préférence prévu deux galets 54 qui seront entraînés selon deux directions opposées et effectueront simultanément le bordage de deux moitiés du périmètre. Des moyens de chauffage 55 tels que deux résistances à fil chauffant sont prévus pour chauffer le profilé avant son pliage et son application au niveau des angles du vitrage.At least one pressure roller 54 controlled by an articulated arm not shown performs the application and compression of the tape 2 against the edge of the glazing 1 over its entire perimeter. To save time in the belt operation, two rollers 54 will preferably be provided which will be driven in two opposite directions and will simultaneously plank two halves of the perimeter. Heating means 55 such as two heating wire resistances are provided for heating the profile before it is folded and applied at the corners of the glazing.
Le fonctionnement du dispositif est le suivant. Les deux feuilles de verre 10, 11 maintenues écartées sont positionnées fixes au centre de la chambre C.The operation of the device is as follows. The two glass sheets 10, 11 kept apart are positioned fixed in the center of the chamber C.
Sous le vitrage est déroulé, étiré et coupé le profilé ou ruban 2 qui comprend le desséchant et les moyens de solidarisation 4.Under the glazing is unrolled, stretched and cut the profile or tape 2 which includes the desiccant and the securing means 4.
Les deux galets presseurs 54 sont amenés au contact du ruban pour appliquer celui-ci en un point milieu du côté horizontal inférieur du vitrage. Une fois le ruban pressé contre la tranche du vitrage, le bordage est amorcé en ce point milieu ce qui assure ainsi la mise sous tension du ruban.The two pressure rollers 54 are brought into contact with the ribbon to apply the latter at a midpoint on the lower horizontal side of the glazing. Once the ribbon is pressed against the edge of the glazing, the planking is started at this midpoint which thus ensures the tensioning of the ribbon.
Les galets 54 progressent ensuite en des directions opposées vers les coins inférieurs gauche 13 et droit 14 du vitrage. Avant d'aborder le tournant des deux angles 13 et 14, les galets 54 sont stoppés momentanément tandis que les fils chauffants 55 sont disposés en aval des galets, proche et en regard du feuillard métallique 21a du profilé pour chauffer la matière thermoplastique destinée à être appliquée contre les angles (figure 3).The rollers 54 then progress in opposite directions towards the lower left 13 and right 14 corners of the glazing. Before approaching the turn of the two angles 13 and 14, the rollers 54 are stopped momentarily while the heating wires 55 are arranged downstream of the rollers, close to and facing the metal strip 21a of the profile to heat the thermoplastic material intended to be applied against the angles (Figure 3).
Après ramollissement du profilé, les galets presseurs 54 sont à nouveau mis en fonctionnement pour plier le profilé et border correctement les angles 13 etAfter softening of the profile, the pressure rollers 54 are again put into operation to fold the profile and correctly border the angles 13 and
14 du vitrage. Puis les galets continuent de parcourir le pourtour du vitrage jusqu'aux angles supérieurs 15 et 16 du vitrage où l'opération de chauffage du profilé est réitérée au moyen des fils chauffants 55.14 of the glazing. Then the rollers continue to run around the periphery of the glazing up to the upper corners 15 and 16 of the glazing where the heating operation of the profile is reiterated by means of the heating wires 55.
Une fois les coins supérieurs du vitrage ceinturés, les galets presseurs 54 finissent de border le dernier côté du vitrage. A l'approche du milieu de ce dernier côté, l'un des galets est arrêté tandis que l'autre galet continue d'écraser le profilé jusqu'à ce que l'extrémité libre 23 du profilé associé à ce galet en fonctionnement recouvre l'autre extrémité 24 du profilé mis en place (figure 4). L'opération de ceinturage est alors terminée, les galets presseurs 54 sont dégagés du vitrage. Pour confirmer la solidarisation des deux extrémités 23 et 24 du ruban et surtout étancher les deux sections latérales ouvertes 25 du ruban qui sont dues au recouvrement des extrémités, des moyens complémentaires d'étanchéité tels que de la colle sont injectés de façon à obturer cesdites sections 25. Une variante d'assemblage non illustrée des deux extrémités du ruban peut consister non pas à les recouvrir mais à les abouter l'une à l'autre lorsqu'elles comprennent des formes complémentaires adaptées à coopérer mutuellement, à la manière d'un tenon et d'une mortaise. Pour assurer la totale étanchéité, on ajoutera sur la zone d'aboutage de la colle ou un ruban adhésif étanche aux gaz et à la vapeur d'eau tel qu'un ruban adhésif en inox.Once the upper corners of the glazing are belted, the pressure rollers 54 finish bordering the last side of the glazing. Approaching the middle of this last side, one of the rollers is stopped while the other roller continues to crush the profile until the free end 23 of the profile associated with this roller in operation covers the 'other end 24 of the profile in place (Figure 4). The belt operation is then completed, the pressure rollers 54 are released from the glazing. To confirm the joining of the two ends 23 and 24 of the ribbon and above all to seal the two open lateral sections 25 of the ribbon which are due to the covering of the ends, complementary sealing means such as glue are injected so as to seal these said sections. 25. An assembly variant not illustrated of the two ends of the ribbon may consist not of covering them but of abutting them to one another when they include complementary shapes adapted to cooperate with each other, in the manner of a tenon and a mortise. To ensure total tightness, glue or a gas-tight and water-vapor-tight adhesive tape such as stainless steel adhesive tape will be added to the butting area.
Si la jonction des deux extrémités du ruban, que ce soit par chevauchement ou par aboutement, est effectuée sur l'un des côtés du vitrage, il est aussi possible de réaliser en variante cette jonction au niveau d'un angle du vitrage.If the junction of the two ends of the strip, whether by overlapping or abutment, is carried out on one of the sides of the glazing, it is also possible as a variant to make this junction at an angle of the glazing.
Par ailleurs, dans une variante de réalisation du procédé, on peut prévoir deux têtes 56a, 56b de distribution du ruban 2, respectivement une fixe et une mobile verticalement, associée chacune à un galet presseur 54, le vitrage étant apte à être translaté horizontalement. En référence à la figure 5a, le vitrage entré dans la chambre C qui n'est ici pas illustrée, est disposé entre la position Φ correspondant à l'avant du vitrage et la position © correspondant à l'arrière du vitrage. Au départ, la tête mobile 56b démarre d'un angle inférieur du vitrage correspondant à la position Φ, et est actionnée vers le haut pour suivre le côté vertical avant du vitrage. Une fois arrivée à l'angle supérieur, la tête 56b pivote de 90° et est immobilisée, les deux têtes étant alors en vis-à-vis. Le vitrage est ensuite translaté de la gauche vers la droite, c'est-à-dire que l'arrière du vitrage passe de la position © vers la position Φ, de manière à effectuer simultanément le ceinturage des côtés horizontaux du vitrage par respectivement chacune des têtes (figure 5b). Enfin, l'arrière du vitrage est immobilisé en position ©, et le côté vertical est ceinturé par la tête mobile ayant pivoté de 90° au coin supérieur du vitrage pour descendre jusqu'à l'angle inférieur (figure 5c). La solidarisation des deux rubans est alors réalisée dans les angles inférieurs du vitrage par chevauchement ou par aboutement.Furthermore, in an alternative embodiment of the method, two heads 56a, 56b for dispensing the tape 2 can be provided, respectively a fixed and a vertically movable head, each associated with a pressure roller 54, the glazing being able to be translated horizontally. With reference to FIG. 5a, the glazing entered into the chamber C which is not illustrated here, is arranged between the position Φ corresponding to the front of the glazing and the position © corresponding to the rear of the glazing. At the start, the movable head 56b starts from a lower angle of the glazing corresponding to the position Φ, and is actuated upwards to follow the front vertical side of the glazing. Once arrived at the upper corner, the head 56b pivots 90 ° and is immobilized, the two heads then being opposite. The glazing is then translated from left to right, that is to say that the rear of the glazing passes from position © to position Φ, so as to simultaneously belt the horizontal sides of the glazing by each respectively heads (Figure 5b). Finally, the rear of the glazing is immobilized in position ©, and the vertical side is surrounded by the movable head having pivoted 90 ° at the upper corner of the glazing to descend to the lower corner (Figure 5c). The two ribbons are joined together in the lower corners of the glazing by overlapping or by abutment.
Cette combinaison des mouvements de translation du vitrage et d'au moins une tête de distribution du ruban permet de gagner du temps pour ceinturer le vitrage.This combination of translation movements of the glazing and at least one tape dispensing head saves time for encircling the glazing.
En outre cette combinaison de mouvements et l'utilisation du profilé de l'invention permet de ceinturer des formes complexes de vitrage qui présentent par exemple des bords courbes à formes concaves et/ou convexes. Une autre variante de remplissage du gaz devant être contenu dans le vitrage peut être envisagée. Au lieu de devoir disposer d'une chambre remplie de gaz, il est prévu un dispositif d'alimentation en gaz tel qu'un tuyau qui est inséré entre les deux verres et qui délivre du gaz au fur et à mesure que les bords du vitrage sont ceinturés et étanchés. Le dispositif est retiré juste avant la fermeture du dernier côté du vitrage.In addition, this combination of movements and the use of the profile of the invention makes it possible to surround complex forms of glazing which for example have curved edges with concave and / or convex shapes. Another variant of filling the gas to be contained in the glazing can be envisaged. Instead of having to have a chamber filled with gas, there is provided a gas supply device such as a pipe which is inserted between the two glasses and which delivers gas as the edges of the glazing are belted and sealed. The device is removed just before closing the last side of the glazing.
Le profilé de l'invention présente une forme générale plate et parallélépipédique, néanmoins des variantes de réalisation sont possibles. Il peut par exemple être envisagé de munir la face interne 20 du profilé opposée à celle comprenant le revêtement métallique, de moyens de centrage et de positionnement tels que des saillies longitudinales ou des ergots répartis régulièrement selon deux lignes longitudinales écartées d'une largeur équivalente à la séparation des deux feuilles de verre de manière à guider et positionner convenablement le profilé contre la tranche du vitrage, les saillies ou ergots s'insérant à l'intérieur du vitrage et étant plaqués contre les parois internes. The profile of the invention has a generally flat and parallelepiped shape, however alternative embodiments are possible. It can for example be envisaged to provide the internal face 20 of the profile opposite to that comprising the metal covering, with centering and positioning means such as longitudinal projections or lugs distributed regularly along two longitudinal lines spaced apart by a width equivalent to the separation of the two glass sheets so as to guide and suitably position the profile against the edge of the glazing, the projections or pins being inserted inside the glazing and being pressed against the internal walls.
