Abstract
Description
La présente invention a pour objet un procédé de fixation étanche d'un double vitrage dans un châssis de menuiserie.The present invention relates to a method of tightly fitting a double glazing in a carpentry frame.
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 celle 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 that 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, on which the glazing bead is placed, and the assembly thus formed is then arranged in a press which secures the various elements 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 provide means in the rebate. water drainage, most often sloping drilling or rebate.
La présente invention a pour but de remédier à ces inconvénients en proposant un procédé de fixation d'un 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 of fixing double glazing which combines the advantage of technically superior results, in particular in terms of sealing, that of authorizing the automation of the production line.
La présente invention a ainsi pour objet un procédé de fixation d'un double vitrage qui se caractérise essentiellement en ce qu'il consiste à couler ou injecter entre le fond de feuillure de la menuiserie et ledit double vitrage un mélange liquide fluide 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 vitrage et son calage d'assise.The present invention thus relates to a method of fixing a double glazing which is essentially characterized in that it consists in casting or injecting between the rebate of the joinery and said double glazing a fluid liquid mixture formed of at least two constituents giving rise to a polymerization reaction at room temperature, leading to the formation of a seal which ensures both the sealing of the glazing and its seat setting.
Conformément au procédé selon l'invention, le double vitrage est dans un premier temps posé dans la feuillure du châssis disposé à plat, et dans un deuxième temps la composition liquide est coulée ou injectée, remplissant tout l'espace disponible entre la feuillure et le vitrage, et s'infiltrant également sous ce dernier.In accordance with the method according to the invention, the double glazing is firstly placed in the rebate of the frame arranged flat, and secondly the liquid composition is poured or injected, filling all the space available between the rebate and the glazing, and also infiltrating under the latter.
La parclose est ensuite fixée soit par des moyens conventionnels soit par collage, après dépôt d'une bande de mastic ou de colle-mastic à la périphérie de la face supérieure du vitrage.The glazing bead is then fixed either by conventional means or by gluing, after depositing a strip of putty or putty adhesive on the periphery of the upper face of the glazing.
La composition mise en oeuvre dans le procédé selon l'invention pour réaliser le joint étanche entre le vitrage et la menuiserie peut être constituée de tout mélange liquide susceptible de donner lieu à une réaction de polymérisation à température ambiante, toutefois elle est avantageusement constituée 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 composition used in the process according to the invention to produce the watertight seal between the glazing and 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 de cisaillement : 8 N/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: 8 N / mm 2.
- 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.
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 following description 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.
Dans le dessin annexé :
- - la figure 1 représente une vue en coupe partielle d'un double vitrage fixé selon le procédé de l'invention à un châssis de fenêtre dont la feuillure comporte une rainure.
- - la figure 2 représente une vue en coupe partielle d'un double vitrage fixé selon le procédé de l'invention, à un châssis de fenêtre dont la feuillure ne comporte aucune rainure.
- - Figure 1 shows a partial sectional view of a double glazing fixed according to the method of the invention to a window frame whose rebate has a groove.
- - Figure 2 shows a partial sectional view of a double glazing fixed according to the method of the invention, to a window frame whose rebate has no groove.
Si on se réfère d'abord à la figure 1, on voit le châssis 1 solidarisé au double vitrage 2 par un joint de polyuréthanne 3 qui remplit l'espace existant entre le fond de feuillure 11 et ledit double vitrage 2, ainsi que celui formé par une rainure 12 ménagée dans la face horizontale de ladite feuillure. Le double vitrage 2, formé de deux vitres 21 et 22 solidarisées par un joint conventionnel 23 formant entretoise, 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 fixée au fond de la 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
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 base 25 du double vitrage 2 et la base 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
On comprend clairement, à l'examen de ces figures, le rôle joué par le joint de polyuréthanne 3, qui assure une solidarisation particulièrement efficace entre le double vitrage 2 et le châssis 1, et qui confère à l'ensemble une étanchéité parfaite, grâce à la continuité dudit joint 3 entre la tranche 24 et la base 25 du double vitrage 2.It is clear on examining these figures, the role played by the
Il convient en particulier de souligner que tout défaut d'assemblage entre les montants et la traverse inférieure du châssis est nécessairement colmaté lors du coulage ou de l'injection du mélange liquide constituant le joint, ce qui explique l'étanchéité parfaite de l'assemblage ainsi réalisé.It should in particular be pointed out that any faulty assembly between the uprights and the lower cross member of the chassis is necessarily sealed during the pouring or injection of the liquid mixture constituting the joint, which explains the perfect tightness of the assembly. thus realized.
Cette totale étanchéité del'assemblage constitue l'un des principaux avantages du procédé selon l'invention, qui permet d'obtenir une feuillure sèche ne nécessitant ni drainage ni ventilation.This total tightness of the assembly constitutes one of the main advantages of the method according to the invention, which makes it possible to obtain a dry rebate 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 entraîne une rigidité nettement supérieure de l'assemblage par rapport aux 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 results in a significantly greater rigidity of the assembly compared to conventional assemblies, and a significantly improved resistance over time.
Enfin, si on plaque le châssis, au cours de la pose du double vitrage, sur une surface plane, le vantail obtenu présente une planéité remarquable, nettement meilleure que celle des vantaux conventionnels.Finally, if the frame is pressed, during the installation of the double glazing, on a flat surface, the leaf obtained has a remarkable flatness, clearly better than that of conventional leaves.
Le procédé selon l'invention joint à ces avantages notables celui de ne pas nécessiter d'opération de pressage pour solidariser l'ensemble formé par le châssis, le vitrage et la parclose, cette dernière perdant d'ailleurs son utilité technique pour ne plus jouer qu'un rôle esthétique.The process according to the invention combines with these notable advantages that of not requiring a pressing operation to secure the assembly formed by the frame, the glazing and the glazing beads, the latter also losing its technical utility so as to no longer play than an aesthetic role.
Le procédé selon l'invention permet ainsi de poser des doubles vitrages d'épaisseur importante dans des feuillures habituelles, du fait que la parclose n'est plus nécessaire pour assurer la tenue mécanique de l'ensemble et qu'un simple habillement avec un plat ou un jonc d'aluminium, de chlorure de polyvinyle ou de caoutchouc suffit pour fermer l'espace existant entre la feuille de verre et la feuillure du châssis.The method according to the invention thus makes it possible to install double glazing of significant thickness in usual rebates, since the glazing bead is no longer necessary to ensure the mechanical strength of the assembly and that a simple clothing with a dish or a strip of aluminum, polyvinyl chloride or rubber is sufficient to close the space existing between the glass sheet and the rebate of the frame.
