Abstract

This procedure consists in using double glazing (2) having no seal (3), and whose seal (3) is produced during manufacture, at the same time as the one which provides the sealing of the assembly and which extends it, by pouring or by injection, between the bottom of the fillister (11) of the frame (1) and the spacer (23) separating the two panes (21, 22) of the said double glazing (2), of a liquid fluid mixture formed from at least two components giving rise to a polymerization reaction at ambient temperature.

Description

La présente invention a pour objet un procédé de fabrication d'un panneau à double vitrage tel qu'un vantail de fenêtre ou de porte-fenêtre ou une baie vitrée fixe.The present invention relates to a method of manufacturing a double-glazed panel such as a window sash or French window or a fixed bay window.

A ce jour la pose industrielle des doubles vitrages s'effectue traditionnellement sur le châssis, généralement en bois, en métal ou en matière plastique, posé sur la chaîne de fabrication, en appliquant dans la feuillure de ce châssis un ruban de mastic sur lequel on pose ensuite le double vitrage, lequel est nécessairement de dimensions légèrement inférieures à celles dudit châssis.To date, the industrial installation of double glazing is traditionally carried out on the frame, generally made of wood, metal or plastic, placed on the production line, by applying a strip of mastic on the rebate of this frame. then installs the double glazing, which is necessarily of dimensions slightly smaller than those of said frame.

L'opération de positionnement du vitrage est difficile à réaliser avec toute la précision souhaitée, et elle est nécessairement suivie de la mise en place de cales de calibres variables que l'opérateur sélectionne et dispose sur les côtés du châssis aux endroits nécessaires, de manière à rattraper les jeux inévitablement créés par la pose et à ce que le double vitrage donne de la rigidité au vantail.The glazing positioning operation is difficult to perform with all the desired precision, and it is necessarily followed by the installation of shims of variable sizes that the operator selects and places on the sides of the frame in the necessary places, so to make up for the play inevitably created by the installation and for the double glazing to give rigidity to the leaf.

Une fois le vitrage posé sur le châssis, on dispose à sa face supérieure et approximativement en regard de la première couche de mastic une deuxième couche de ce produit, sur laquelle on pose la parclose, et l'ensemble ainsi formé est ensuite disposé dans une presse qui en solidarise les différents éléments par écrasement du mastic. La parclose est ensuite fixée au châssis, généralement par clouage ou vissage.Once the glazing has been placed on the frame, a second layer of this product is placed on its upper face and approximately opposite the first layer of mastic. the glazing bead, and the assembly thus formed is then placed in a press which secures the various elements thereof by crushing the putty. The glazing bead is then fixed to the frame, generally by nailing or screwing.

Ce procédé présente des inconvénients car il nécessite des temps de fabrication relativement longs en raison des opérations successives qui doivent être effectuées manuellement, ce qui entraîne des coûts de main d'oeuvre importants. De plus, le panneau vitré ainsi réalisé présente des risques de fuite, notamment au niveau des assemblages inférieurs, d'où la nécessité de compléter l'étanchéité par un dépôt supplémentaire de mastic appliqué au droit des assemblages, et de ménager dans la feuillure des moyens de drainage de l'eau, le plus souvent perçage ou feuillure en pente.This method has drawbacks because it requires relatively long manufacturing times due to the successive operations which must be carried out manually, which results in significant labor costs. In addition, the glazed panel thus produced presents risks of leakage, in particular at the level of the lower assemblies, hence the need to complete the sealing with an additional deposit of mastic applied to the right of the assemblies, and to spare in the rebate of the means of water drainage, usually drilling or sloping rebate.

La présente invention a pour but de remédier à ces inconvénients en proposant un procédé de réalisation d'un panneau à double vitrage qui joint à l'avantage de résultats techniquement supérieurs, notamment au plan de l'étanchéité, celui d'autoriser l'automatisation de la chaîne de fabrication.The object of the present invention is to remedy these drawbacks by proposing a method for producing a double-glazed panel which combines the advantage of technically superior results, in particular in terms of sealing, with that of authorizing automation. of the production line.

La présente invention a ainsi pour objet un procédé de fabrication d'un panneau à double vitrage qui se caractérise essentiellement en ce qu'il consiste à mettre en oeuvre un double vitrage dont le joint externe, d'étanchéité, est réalisé in situ, en même temps que son assemblage au châssis de menuiserie, par coulage ou injection, entre le fond de feuillure et l'entretoise séparant les deux feuilles dudit double vitrage, d'un mélange liquide formé d'au moins deux constituants donnant lieu à une réaction de polymérisation à température ambiante, conduisant à la formation d'un joint qui assure à la fois l'étanchéité du panneau et son calage d'assise.The present invention thus relates to a method of manufacturing a double-glazed panel which is essentially characterized in that it consists in using a double-glazed window whose external seal is made in situ, in at the same time as its assembly to the carpentry frame, by casting or injection, between the rebate bottom and the spacer separating the two sheets of said double glazing, of a liquid mixture formed of at least two constituents giving rise to a reaction of polymerization at room temperature, leading to the formation of a seal which ensures both the tightness of the panel and its seat setting.

Conformément au procédé selon l'invention, les deux feuilles de verre réunies par une entretoise disposée à une courte distance de leur périphérie sont disposées dans la feuillure du châssis posé à plat préalablement à l'injection ou au coulage du mélange liquide qui remplit tout l'espace disponible entre la feuillure et l'entretoise. La parclose est ensuite posée et fixée soit par des moyens conventionnels, soit par collage.According to the method according to the invention, the two glass sheets joined by a spacer placed a short distance from their periphery are arranged in the rebate of the chassis laid flat before injection or pouring of the liquid mixture which fills all the space available between the rebate and the spacer. The glazing bead is then laid and fixed either by conventional means or by gluing.

Le mélange mis en oeuvre dans le procédé selon l'invention pour réaliser à la fois le joint étanche du double vitrage et celui le réunissant à la menuiserie peut être constitué de tout mélange liquide susceptible de donner lieu à une réaction de polymérisation à température ambiante, toutefois il est avantageusement constitué du mélange, réalisé au moment de l'emploi, d'un isocyanate et d'un polyol, conduisant à la formation in situ d'un polyuréthanne.The mixture used in the process according to the invention to produce both the tight seal of the double glazing and that joining it to the joinery can consist of any liquid mixture capable of giving rise to a polymerization reaction at room temperature, however, it advantageously consists of the mixture, produced at the time of use, of an isocyanate and a polyol, leading to the in situ formation of a polyurethane.

Selon un mode de réalisation préférentiel du procédé selon l'invention, le mélange mis en oeuvre est tel que la réticulation du polyuréthanne intervienne dans un laps de temps de l'ordre de quelques dizaines de secondes.According to a preferred embodiment of the method according to the invention, the mixture used is such that the crosslinking of the polyurethane takes place within a period of time of the order of a few tens of seconds.

A cet effet, le mélange de départ peut être celui constitué par un polyol dont la viscosité est de 9 à 10.000 mP/s à 20°C et la densité à la même température de 1,45 et d'un 4,4′-diisocyanate de diphénylméthane de viscosité 180 à 200 mP/s et de densité 1,22 à 20°C, le rapport pondéral du mélange étant de 100 parties de polyol pour 25 parties d'isocyanate. Le mélange, injecté en l'espace de quelques secondes, donne un joint dont les caractéristiques physiques à 20°C sont les suivantes:
- temps de gélification : 12 s.
- temps de prise : 2 mn 30 s à 3 mn 30 s.
- contrainte au cisaillement : 8N/mm².
- valeur de collage : 30 à 40 N/cm.For this purpose, the starting mixture can be that constituted by a polyol whose viscosity is from 9 to 10,000 mP / s at 20 ° C and the density at the same temperature of 1.45 and a 4.4′- diphenylmethane diisocyanate with a viscosity of 180 to 200 mP / s and a density of 1.22 at 20 ° C., the weight ratio of the mixture being 100 parts of polyol per 25 parts of isocyanate. The mixture, injected within a few seconds, gives a joint whose physical characteristics at 20 ° C are as follows:
- gel time: 12 s.
- setting time: 2 min 30 s to 3 min 30 s.
- shear stress: 8N / mm².
- bonding value: 30 to 40 N / cm.

Afin d'améliorer la solidarisation du vitrage au châssis, il est possible de ménager sur la face horizontale de la feuillure une rainure prolongeant l'espace existant entre l'extrémité du double vitrage et le fond de ladite feuillure et destinée à recevoir la composition liquide formant le joint.In order to improve the joining of the glazing to the frame, it is possible to provide on the horizontal face of the rebate a groove extending the space existing between the end of the double glazing and the bottom of said rebate and intended to receive the liquid composition forming the joint.

Il convient de souligner que le procédé selon l'invention offre la possibilité de réaliser in situ le double vitrage, en procédant d'abord à la pose de la première feuille de verre dans le châssis, puis à la mise en place de l'entretoise, suivie de la pose de la seconde feuille de verre. Le mélange liquide est ensuite coulé ou injecté de manière à créer le joint d'étanchéité du double vitrage et à le solidariser au châssis de manière étanche.It should be emphasized that the method according to the invention offers the possibility of producing double glazing in situ, first by laying the first sheet of glass in the frame, then by placing the spacer. , followed by the installation of the second sheet of glass. The liquid mixture is then poured or injected so as to create the seal for the double glazing and to secure it to the frame in a leaktight manner.

Le procédé selon l'invention permet en outre de fabriquer un panneau vitré à partir de ses divers éléments constitutifs séparés, par assemblage in situ, ce qui constitue un autre avantage par rapport aux procédés existants, dans lesquels le double vitrage déjà formé est inséré dans le châssis préalablement constitué. On peut ainsi commencer par assembler les éléments constitutifs du châssis munis à leurs faces d'assemblage de rainures en regard débouchant dans la feuillure, puis poser dans la feuillure la première feuille de verre, mettre en place l'entretoise, poser la deuxième feuille de verre et procéder ensuite au coulage et à l'injection du mélange liquide. On peut aussi réaliser l'assemblage des différents éléments du châssis autour de la première feuille de verre avant de procéder à la mise en place de l'entretoise et de la deuxième feuille de verre, en supprimant ainsi l'opération préliminaire de cadrage du châssis.The method according to the invention also makes it possible to manufacture a glazed panel from its various separate constituent elements, by assembly in situ, which constitutes another advantage compared to existing methods, in which the already formed double glazing is inserted into the previously constituted chassis. We can thus start by assembling the constituent elements of the chassis provided on their assembly faces with facing grooves opening into the rebate, then place in the rebate the first sheet of glass, place the spacer, place the second sheet of glass and then pour and inject the liquid mixture. It is also possible to assemble the various elements of the frame around the first sheet of glass before proceeding with the installation of the spacer and the second sheet of glass, thereby eliminating the preliminary operation of framing the frame. .

L'avantage de cette façon de procéder réside dans une solidarisation accrue des différents éléments du panneau vitré, résultant en une étanchéité parfaite du panneau obtenu, dont la rigidité et la planéité sont notablement améliorées par rapport à celles des panneaux conventionnels.The advantage of this way of proceeding resides in an increased joining of the different elements of the glazed panel, resulting in a perfect seal of the panel obtained, the rigidity and flatness of which are notably improved compared to those of conventional panels.

Cet avantage entraîne l'avantage supplémentaire d'autoriser la suppression de la parclose, qui peut être remplacée par un joint souple fixé au châssis par collage. Un tel joint peut avantageusement présenter un profil en té de manière à assurer sa meilleure solidarisation au joint d'étanchéité, étant dans ce cas posé immédiatement après le coulage du mélange liquide qui constitue ce dernier et dans lequel il est partiellement immergé. Ce joint souple peut être réalisé en tout matériau approprié tel que métal ou matière plastique, et notamment en aluminium, en chlorure de polyvinyle ou en caoutchouc.This advantage leads to the additional advantage of authorizing the removal of the glazing bead, which can be replaced by a flexible seal fixed to the frame by gluing. Such a seal may advantageously have a tee profile so as to ensure its best attachment to the seal, being in this case placed immediately after pouring of the liquid mixture which constitutes the latter and in which it is partially immersed. This flexible seal can be made of any suitable material such as metal or plastic, and in particular aluminum, polyvinyl chloride or rubber.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description qui suit d'un de ses modes de réalisation illustré par le dessin annexé, étant bien entendu que cette description ne présente aucun caractère limitatif vis-à-vis de l'invention.Other characteristics and advantages of the present invention will emerge from the description which follows of one of its embodiments illustrated by the appended drawing, it being understood that this description has no limiting character with respect to the invention .

  • - la figure 2 représente une vue en coupe partielle d'un panneau vitré dont la feuillure ne comporte pas de rainure.

In the attached drawing:
  • - Figure 1 shows a partial sectional view of a glazed panel whose rebate has a groove.
  • - Figure 2 shows a partial sectional view of a glazed panel whose rebate does not have a groove.
  • - Figure 3 shows a partial sectional view of a glass panel having no glazing bead.

Si on se réfère d'abord à la figure 1, on voit le châssis 1 du panneau solidarisé au double vitrage 2 par un joint de polyuréthanne 3 qui remplit d'une part l'espace existant entre le fond de feuillure 11 et ledit double vitrage, d'autre part celui existant dans le double vitrage lui-même en raison de l'absence de joint d'étanchéité, et enfin l'espace formé par une rainure 12 ménagée dans la face horizontale de la feuillure. Le double vitrage 2, formé de deux feuilles de verre 21 et 22 solidarisées par une entretoise 23, porte à la périphérie de sa face supérieure un joint conventionnel 4 fait de mastic, de colle ou de colle-mastic, destiné à le solidariser à la parclose 5, laquelle est fixée au fond de feuillure 11 par des moyens conventionnels non représentés tels que vis ou clous, ou encore par collage.If we refer first to Figure 1, we see the frame 1 of the panel secured to the double glazing 2 by a polyurethane gasket 3 which firstly fills the space between the rebate base 11 and said double glazing , on the other hand that existing in the double glazing itself due to the absence of a seal, and finally the space formed by a groove 12 formed in the horizontal face of the rebate. The double glazing 2, formed by two sheets of glass 21 and 22 secured by a spacer 23, carries at the periphery of its upper face a conventional seal 4 made of mastic, glue or glue-mastic, intended to secure it to the glazing bead 5, which is fixed to the rebate bottom 11 by conventional means not shown such as screws or nails, or by gluing.

Si on se réfère ensuite à la figure 2, on retrouve les mêmes éléments qu'à la figure 1, à la rainure 12 près : dans ce cas le mélange constituant le joint 3 de polyuréthanne s'infiltre entre la face inférieure 25 du double vitrage et la face correspondante de la feuillure, contribuant à la solidarisation du double vitrage 2 au châssis 1.If we then refer to Figure 2, we find the same elements as in Figure 1, except for groove 12: in this case the mixture constituting the polyurethane seal 3 infiltrates between the underside 25 of the double glazing and the corresponding face of the rebate, contributing to the securing of the double glazing 2 to the frame 1.

Si on se réfère enfin à la figure 3, on retrouve les mêmes éléments qu'à la figure 2, à la parclose 5 près, qui est remplacée par un joint 26 à profil en té dont la face inférieure comporte une lèvre 27 destinée à être immergée dans le mélange liquide qui forme le joint d'étanchéité 3 avant sa polymérisation, de manière à assurer la solidarisation efficace dudit joint 26, lequel peut être réalisé en tout matériau approprié tel que métal ou matière plastique.If we finally refer to FIG. 3, we find the same elements as in FIG. 2, except for the glazing bead 5, which is replaced by a gasket 26 with a tee profile, the lower face of which comprises a lip 27 intended to be immersed in the liquid mixture which forms the seal 3 before its polymerization, so as to ensure effective joining of said seal 26, which can be made of any suitable material such as metal or plastic.

On comprend clairement, à l'examen de ces figures, le rôle joué par le joint de polyuréthanne 3, qui assure d'une part une solidarisation extrêmement efficace du double vitrage 2 au châssis 1, et d'autre part l'étanchéité parfaite tant du double vitrage lui-même que de l'assemblage.It is clearly understood, on examination of these figures, the role played by the polyurethane seal 3, which ensures on the one hand an extremely effective attachment of the double glazing 2 to the frame 1, and on the other hand the perfect sealing as double glazing itself than assembly.

Cette étanchéité parfaite de l'assemblage constitue l'un des principaux avantages du procédé selon l'invention, la feuillure du panneau vitré ne nécessitant ni drainage ni ventilation.This perfect tightness of the assembly constitutes one of the main advantages of the method according to the invention, the rebate of the glazed panel requiring neither drainage nor ventilation.

A cet avantage s'ajoute celui constitué par le fait que le double vitrage se trouve scellé dans le châssis, ce qui a pour effet particulièrement avantageux de conférer à l'assemblage une rigidité nettement supérieure à celle des assemblages conventionnels, et une tenue dans le temps nettement améliorée.To this advantage is added that constituted by the fact that the double glazing is sealed in the frame, which has the particularly advantageous effect of giving the assembly a rigidity markedly greater than that of conventional assemblies, and a resistance in the significantly improved time.

En outre, ainsi qu'il a déjà été dit, le procédé selon l'invention présente également l'avantage d'autoriser une variété de modes d'assemblage des éléments constituant le panneau vitré, permettant de partir soit d'un châssis déjà formé soit des différentes pièces qui le constituent, et soit d'un double vitrage déjà formé, au joint d'étanchéité près, soit des feuilles de verre qui le constituent.In addition, as has already been said, the method according to the invention also has the advantage of authorizing a variety of methods of assembling the elements constituting the glazed panel, making it possible to start from either an already formed chassis either of the various parts which constitute it, and either of a double glazing already formed, close to the seal, or of the sheets of glass which constitute it.

Le procédé selon l'invention joint à ces avantages celui de ne pas nécessiter d'opération de pressage pour solidariser l'assemblage, et de permettre la pose de doubles vitrages d'épaisseur importante dans les feuillures habituelles, du fait que la parclose ne sert plus à assurer la tenue mécanique de l'ensemble, se limitant à un rôle de finition, et pouvant être remplacée par un plat ou un jonc souple fixé au châssis par collage.The process according to the invention combines with these advantages that of not requiring a pressing operation to securing the assembly, and allowing the installation of double glazing of significant thickness in the usual rebates, the fact that the glazing bead no longer serves to ensure the mechanical strength of the assembly, being limited to a finishing role, and being able to be replaced by a flexible plate or rod fixed to the chassis by gluing.
