Description
La présente invention est du domaine du vitrage, et concerne en particulier le châssis destiné à supporter des vitrages multiples, tels qu'un double vitrage, pour le bâtiment. L'invention trouve son application aussi bien dans le domaine du vitrage à panneaux fixes que dans le vitrage à panneaux coulissants, tel que ceux qui équipent les baies vitrées.The present invention is in the field of glazing, and relates in particular to the frame for supporting multiple glazing, such as double glazing, for the building. The invention finds its application both in the field of fixed panel glazing as in the sliding panel glazing, such as those that equip the windows.
Les châssis pour double vitrage comportent le plus souvent une menuiserie en bois, en aluminium ou en matière plastique telle que le PVC. Ce type de système intègre un ensemble de profilés qui doivent venir emprisonner les bords d'un vitrage de manière jointive. Un espace, de préférence d'au moins 5 mm, doit être ménagé entre les chants du vitrage et les éléments des profilés qui lui font face. Un tel espace garantit un écoulement de l'eau et une évacuation de la vapeur d'eau vers des sorties qui communiquent avec le milieu extérieur. La rétention d'eau sur les chants du vitrage est à proscrire pour éviter la dégradation du vitrage. Cependant, la présence de cet espace nécessaire à l'évacuation de l'humidité altère considérablement les performances thermiques du vitrage. Des doubles vitrages configurés de cette sorte sont, par exemple, décrits dans le document
Pour diminuer les déperditions thermiques dans les espaces nécessaires à l'évacuation de l'eau, des systèmes ont été conçus tels que la mise en place d'un profilé supplémentaire tout le long du chant du vitrage, comme cela est décrit dans le document
Il est également connu de recourir à l'usage d'un ensemble de joints brosse qui viennent directement en contact avec le chant du vitrage depuis l'intérieur de la menuiserie. La demande
Le recours à la technique de coextrusion est connu dans le domaine du vitrage et concerne plus particulièrement les garnitures d'étanchéité qui équipent l'intérieur et l'extérieur du vitrage tel que cela est décrit dans la demande de brevet
Pour pallier tout ou partie des inconvénients de l'état de la technique précité, la présente invention concerne un intercalaire de coupure thermique comprenant une première face prévue pour venir en appui sur le chant d'un vitrage en s'étendant sensiblement sur toute sa longueur, et une deuxième face prévue pour être fixée sur l'un des profilés du châssis de la menuiserie dudit vitrage, caractérisé en ce que ladite première face comprend une lamelle souple en plastique extrudé. Ladite première face comprend avantageusement au moins deux lamelles souples en plastique extrudé. Les lamelles souples s'étendent sensiblement sur toute la longueur de l'intercalaire, et de préférence sur toute la longueur de la partie de l'intercalaire qui est positionnée en vis-à-vis du chant du vitrage. Les lamelles souples sont avantageusement positionnées parallèlement les unes par rapport aux autres. Grâce aux interstices ménagés entre les lamelles souples qui viennent au contact du vitrage, la déperdition thermique est évitée. Les interstices entre les lamelles souples ménagent un réseau de canalisations à l'intérieur des montants de la menuiserie pour évacuer les liquides et empêcher la condensation, tout en garantissant un gain thermique.To overcome all or part of the drawbacks of the state of the art cited above, the present invention relates to a thermal cut-off interlayer comprising a first face provided to rest on the edge of a glazing extending substantially over its entire length. , and a second face intended to be fixed on one of the frame profiles of the joinery of said glazing unit, characterized in that said first face comprises an extruded plastic flexible blade. Said first face advantageously comprises at least two flexible strips of extruded plastic. The flexible strips extend substantially over the entire length of the spacer, and preferably over the entire length of the portion of the spacer which is positioned vis-à-vis the edge of the glazing. The flexible strips are advantageously positioned parallel to each other. Thanks to the interstices formed between the flexible strips that come into contact with the glazing, thermal loss is avoided. The interstices between the flexible lamellae provide a network of pipes inside the carpentry posts to evacuate the liquids and prevent condensation, while guaranteeing a thermal gain.
Selon des modes de réalisation avantageux, l'intercalaire consiste (uniquement) en des lamelles extrudées, au moins au nombre de deux, qualifiées de lamelles de coupure thermique qui sont fixées sur un montant de la menuiserie d'un élément vitré et viennent en appui sur le chant dudit vitrage.According to advantageous embodiments, the interlayer consists (only) in extruded strips, at least two in number, qualified as thermal cut-off lamellae which are fixed on an amount of the joinery of a glazed element and come to bear on the edge of said glazing.
Les panneaux vitrés qui équipent les fenêtres ou les baies vitrées des bâtiments comprennent un vitrage, le plus souvent un double vitrage, qui est enchâssé dans une menuiserie. Pour les panneaux vitrés rectangulaires, la menuiserie comprend quatre montants formant le châssis, chaque montant étant constitué d'un ensemble de profilés. Dans certains cas, en plus du châssis la menuiserie comprend quatre parcloses qui viennent fermer la menuiserie sur le vitrage en façade. Pour le cas des baies vitrées pour lesquelles le montage se fait sans parclose , les quatre montants sont encastrés directement latéralement sur le vitrage, puis maintenus par vissage après pressage.The glazed panels that equip windows or bay windows of buildings include glazing, usually double glazing, which is enshrined in a carpentry. For rectangular glazed panels, the joinery comprises four uprights forming the frame, each upright consisting of a set of profiles. In some cases, in addition to the frame, the carpentry includes four glazing stops that close the carpentry on the glazing facade. For the bay windows for which the assembly is done without bead, the four uprights are embedded directly laterally on the glazing, then held by screwing after pressing.
Grâce à l'intercalaire selon la présente invention, la formation de ponts thermiques entre le vitrage et le châssis est considérablement réduite : il n'y a plus de zones entièrement vides entre les deux faces du châssis qui doivent s'ériger de part et d'autre des bordures du vitrage. La fabrication des lamelles souples extrudées permet d'assurer une liaison parfaite entre le châssis et le vitrage, et la production en série avec des cadences de production élevées est facilitée. La fixation de l'intercalaire sur le reste de la menuiserie permet de fabriquer des montants déjà prêts au montage en sortie d'usine et sans qu'il soit nécessaire de rapporter des pièces détachées au moment du montage de la baie vitrée. La fabrication des lamelles souples est réalisable sur des profilés existant dans la menuiserie; alternativement l'intercalaire peut être une pièce supplémentaire qui est fixée sur le châssis au cours de la réalisation de la menuiserie. Le mode de fabrication par extrusion et l'intégration par fixation de l'intercalaire au châssis rend entièrement compatible l'intercalaire selon l'invention avec un assemblage des montants d'une menuiserie sur un vitrage coulissant.Thanks to the interlayer according to the present invention, the formation of thermal bridges between the glazing unit and the chassis is considerably reduced: there are no more completely empty zones between the two sides of the chassis which must erect on both sides. other edges of the glazing. The manufacture of extruded flexible strips ensures a perfect connection between the frame and the glazing, and mass production with high production rates is facilitated. The fixing of the interlayer on the rest of the joinery makes it possible to manufacture amounts already ready for mounting at the factory outlet and without the need to bring spare parts at the time of assembly of the bay window. The manufacture of flexible strips is feasible on existing profiles in the carpentry; alternatively the interlayer may be an additional piece which is attached to the frame during the realization of the joinery. The extrusion manufacturing method and the integration by fixing the interlayer to the frame makes it fully compatible the interlayer according to the invention with an assembly of the amounts of a joinery on a sliding glazing.
Avantageusement la première face de l'intercalaire comprend un matériau plastique et les lamelles souples en plastique sont extrudées sur ledit matériau plastique. L'extrusion, voire la coextrusion, des lamelles sur un intercalaire en tout ou partie plastique facilite la fabrication, ce qui permet de réaliser rapidement par plasturgie les pièces de la menuiserie.Advantageously, the first face of the insert comprises a plastic material and the flexible plastic strips are extruded on said plastic material. The extrusion, or even the coextrusion, of the slats on a spacer in all or part plastic facilitates the manufacture, which allows to quickly realize by plastics parts of the joinery.
La deuxième face de l'intercalaire selon l'invention comporte avantageusement au moins un moyen de clipsage de l'intercalaire configuré pour un clipsage dans un rainurage du châssis de la menuiserie du vitrage. Par clipsage, il faut comprendre dans le cadre de l'invention une opération pouvant également être qualifiée par le terme équivalent d'encliquetage. La menuiserie comporte avantageusement des rainurages pour encliqueter l'intercalaire sur un montant du châssis. L'intercalaire est de préférence composé en partie ou intégralement de plastique, ce qui facilite sont encliquetage sur le reste de la menuiserie. Le moyen d'encliquetage est de préférence une ailette en plastique rigide, il peut également s'agir d'un renfort qui vient doubler une bordure de l'intercalaire. De manière alternative, un profilé en matière plastique déjà présent dans le montant du châssis, et adapté pour être assemblé au reste du montant par clipsage, est extrudé pour obtenir les lamelles souples et constitue ainsi un intercalaire selon l'invention.The second face of the interlayer according to the invention advantageously comprises at least one clipping means of the insert configured for clipping in a grooving of the frame of the joinery of the glazing. By clipping, it is understood in the context of the invention an operation that can also be qualified by the equivalent term of latching. The joinery advantageously comprises grooves for snapping the spacer on a frame upright. The interlayer is preferably composed in part or entirely of plastic, which facilitates snapping on the rest of the joinery. The snap means is preferably a rigid plastic fin, it may also be a reinforcement that doubles a border of the spacer. Alternatively, a plastic profile already present in the frame of the frame, and adapted to be assembled to the rest of the amount by clipping, is extruded to obtain the flexible strips and thus constitutes a spacer according to the invention.
Les lamelles souples de l'intercalaire selon l'invention sont avantageusement préparées par extrusion avec le matériau plastique selon un procédé de coextrusion. Le matériau plastique de la première face de l'intercalaire est coextrudé avec les lamelles souples qui s'érigent sensiblement perpendiculairement à cette première face. La coextrusion est un procédé d'extrusion qui permet d'obtenir un produit associant deux textures. Le principe de la coextrusion repose sur la mise en fonctionnement de plusieurs vis d'extrusion pour extruder plusieurs couches de polymère. La coextrusion permet de réaliser l'extrusion des différentes parties d'un produit en simultané, à l'inverse de la surextrusion qui consiste en la réalisation de plusieurs étapes d'extrusion les unes après les autres.The flexible strips of the interlayer according to the invention are advantageously prepared by extrusion with the plastic material according to a coextrusion process. The plastic material of the first face of the interlayer is coextruded with the flexible strips which are substantially perpendicular to this first face. Coextrusion is an extrusion process that produces a product that combines two textures. The principle of coextrusion is based on the operation of several extrusion screws to extrude several layers of polymer. Coextrusion allows the extrusion of different parts of a product simultaneously, in contrast to overextrusion which consists of carrying out several extrusion steps one after the other.
L'intercalaire est avantageusement préparé par coextrusion d'un seul polymère en deux couches, une première couche formant le matériau plastique de la première face de l'intercalaire, une deuxième couche formant les lamelles souples qui s'étendent sur ledit matériau plastique.The interlayer is advantageously prepared by coextrusion of a single polymer in two layers, a first layer forming the plastic material of the first face of the interlayer, a second layer forming the flexible lamellae which extend over said plastic material.
Alternativement, l'intercalaire est avantageusement préparé par surextrusion des lamelles souples sur le matériau plastique de la première face de l'intercalaire de coupure thermique selon l'invention. La surextrusion implique que l'extrusion du corps de l'intercalaire est mise en oeuvre dans une première étape, puis une deuxième extrusion est mise en oeuvre dans une deuxième étape pour réaliser les lamelles souples qui s'érigent sur le corps de l'intercalaire.Alternatively, the interlayer is advantageously prepared by over-extrusion of the flexible strips on the plastic material of the first face of the thermal cut-off interlayer according to the invention. Over-extrusion implies that the extrusion of the body of the interlayer is implemented in a first step, then a second extrusion is implemented in a second step to achieve the flexible strips that are erected on the body of the interlayer .
Les lamelles souples selon l'invention peuvent comporter un évidemment, et lesdites lamelles sont avantageusement sensiblement de forme tubulaire. Une telle conformation tubulaire facilite la fabrication des lamelles sur un support plastique selon des opérations de coextrusion ou de surextrusion.The flexible slats according to the invention may comprise a recess, and said slats are advantageously substantially of tubular shape. Such a tubular conformation facilitates the manufacture of the slats on a plastic support according to coextrusion or overextrusion operations.
L'intercalaire est avantageusement intégralement composé d'un matériau plastique, réalisé en plusieurs couches par coextrusion, surextrusion, voire surmoulage.The interlayer is advantageously integrally composed of a plastic material, made in several layers by coextrusion, overextrusion or overmolding.
Le matériau polymère entrant dans la composition du matériau plastique ou des lamelles souples de l'intercalaire selon l'invention est avantageusement un polymère ou un copolymère sélectionné parmi au moins l'un des éléments suivant : un polychlorure de vinyle (PVC), un acrylonitrile butadiène styrène (ABS), un styrène-acrylonitrile (SAN), un polyméthacrylate de méthyle (PMMA), un polyéthylène (PE) tel que le polyéthylène haute densité (PE-HD), un polypropylène (PP), un polyamide, un polytéréphtalate d'éthylène (PET), un polyuréthane (PU), un polyacétal, et un polyester.The polymeric material used in the composition of the plastic material or the flexible lamellae of the interlayer according to the invention is advantageously a polymer or a copolymer selected from at least one of the following elements: a polyvinyl chloride (PVC), an acrylonitrile butadiene styrene (ABS), styrene-acrylonitrile (SAN), polymethylmethacrylate (PMMA), polyethylene (PE) such as high-density polyethylene (PE-HD), polypropylene (PP), polyamide, polyethylene terephthalate (PET), polyurethane (PU), polyacetal, and polyester.
Avantageusement l'intercalaire comprend trois ou quatre lamelles souples. Le nombre de trois à quatre est à la fois suffisant pour garantir une amélioration significative des performances thermiques et permet de pouvoir réaliser des lamelles facilement accessibles par extrusion de par leurs dimensions.Advantageously, the interlayer comprises three or four flexible strips. The number of three to four is both sufficient to ensure a significant improvement in thermal performance and allows to achieve slats easily accessible by extrusion by their dimensions.
