Description

La présente invention est relative à un dispositif de rupture thermique pour profilés métalliques, notamment en aluminium, qui forment le cadre d'un panneau vitré ou analogue, ce dispositif assurant une limitation de la transmission de la chaleur ou du froid par conduction à la traversée de ces profilés, en particulier entre l'extérieur et l'intérieur d'une façade du genre dit à mur rideau d'un bâtiment ou d'une construction similaire.The present invention relates to a device for thermal break for metal profiles, especially in aluminum, which form the frame of a glass panel or similar, this device ensuring a limitation of the transmission of heat or cold by conduction to the crossing of these profiles, in particular between the exterior and the interior of a facade like the curtain wall of a building or similar construction.

On sait que dans une telle façade, celle-ci comporte une ossature de support réalisée à l'aide de montants verticaux et de traverses horizontales, appliquée contre le gros oeuvre du bâtiment et délimitant entre eux des alvéoles adjacents où sont logés des panneaux de remplissage du genre ci-dessus, ces panneaux étant appliqués contre le fond de ces alvéoles, de sorte que la façade semble pratiquement formée, vue de l'extérieur, avec ces seuls panneaux, sans que l'ossature soit elle-même apparente.We know that in such a facade, it has a support frame made using vertical uprights and horizontal sleepers, applied against the large building work and delimiting cells between them adjacent where the filling panels of the genre above, these panels being applied against the bottom of these cells, so that the facade seems practically formed, seen from the outside, with these only panels, without the framework itself being visible.

Les profilés métalliques classiques qui rentrent dans la réalisation d'une telle façade, notamment pour constituer le cadre ou châssis de chaque panneau avant montage de celui-ci dans le fond des alvéoles de l'ossature, sont usuellement réalisés au moyen de deux parties accolées, séparées par des barrettes d'un matériau mauvais conducteur de la chaleur, notamment des barrettes de polyamide ou similaire, qui s'étendent dans le sens allant de l'extérieur vers l'intérieur du bâtiment ou vice versa, perpendiculairement au plan des panneaux de remplissage.The classic metal profiles that fit into the realization of such a facade, in particular to constitute the frame or chassis of each front panel mounting this one in the bottom of the cells of the frame, are usually made by means of two adjoining parts, separated by bars of bad conductive material heat, in particular polyamide strips or similar, which extend in the direction from outside to inside the building or vice versa, perpendicular to the plane of the filling panels.

Cette solution à barrettes isolantes, destinée à réaliser une rupture de pont thermique entre de chaque côté du profilé qui forme le cadre d'un panneau, présente les inconvénients d'être relativement encombrante et d'un coût plutôt élevé.This solution with insulating bars, intended to realize a thermal break between each side of the profile which forms the frame of a panel, presents the disadvantages of being relatively bulky and costly rather high.

En outre, le positionnement des barrettes sur les deux parties du profilé pour les réunir mutuellement n'est pas aisé, notamment si le cadre recevant chaque panneau vitré ou non est équipé d'une parclose, c'est-à-dire d'un élément périphérique qui prolonge le cadre vers la surface externe du panneau et comporte un retour parallèle à celui-ci pour le maintenir par ses bords latéraux appliqué contre le fond de l'alvéole de l'ossature qui le reçoit.In addition, the positioning of the bars on the two parts of the profile to join them together is not easy, especially if the frame receiving each glass panel or not is equipped with a glazing bead, i.e. an element device which extends the frame towards the external surface of the panel and has a return parallel to it for hold it by its side edges applied against the bottom of the socket of the frame which receives it.

La présente invention a pour objet un dispositif qui permet d'obtenir une rupture de pont thermique dans des conditions plus efficaces avec des moyens plus simples et moins onéreux que dans les solutions classiques connues dans la technique.The present invention relates to a device which allows to obtain a thermal break under conditions more effective with simpler and less expensive than in conventional solutions known in the art technical.

A cet effet, le dispositif considéré, adapté à être monté dans un profilé métallique tubulaire formant le cadre de réception d'un panneau de remplissage logé dans un alvéole de réception prévu dans une ossature de support d'une façade de mur rideau vertical, se caractérise en ce qu'il comporte un élément de structure formant bouclier thermique, intégré au profilé et réalisé en un matériau isolant, cet élément de structure qui enveloppe le cadre étant disposé sur le pourtour du panneau au droit et en regard du bord extérieur périphérique de celui-ci, le panneau de remplissage reposant directement sur cet élément. To this end, the device considered, adapted to be mounted in a tubular metal profile forming the frame of reception of a filling panel housed in a cell reception provided in a support frame of a vertical curtain wall facade, characterized in that it includes a structural element forming a shield thermal, integrated into the profile and made of a material insulating, this structural element that envelops the frame being arranged on the periphery of the panel at the right and in look at the peripheral outer edge of it, the filling panel resting directly on this element.

Dans une première variante de réalisation, le panneau de remplissage est collé contre le profilé métallique.In a first alternative embodiment, the panel filling is glued against the metal profile.

Dans une autre variante, le panneau de remplissage est appliqué contre le profilé métallique au moyen d'une parclose, présentant un retour plan muni d'un joint d'étanchéité, s'étendant parallèlement au panneau et en appui contre la surface externe de celui-ci.In another variant, the filling panel is applied against the metal profile by means of a glazing bead, presenting a flat return fitted with a seal sealing, extending parallel to the panel and support against the external surface thereof.

Selon une autre caractéristique de l'invention, l'élément de structure formant bouclier thermique est serti sur le profilé métallique du cadre. En variante, cet élément est fixé à la manière d'un clip sur ce profilé.According to another characteristic of the invention, the element of structure forming heat shield is crimped on the metal frame profile. Alternatively, this element is fixed like a clip on this profile.

Selon encore une autre caractéristique de l'invention, le panneau de remplissage porte sur le profilé du cadre au droit de l'élément de structure formant bouclier thermique par l'intermédiaire d'au moins une cale d'appui, disposée sous le bord inférieur du panneau.According to yet another characteristic of the invention, the filler panel door on the frame profile at right of the structural element forming a heat shield by means of at least one support wedge, arranged under the lower edge of the panel.

Selon également une autre caractéristique, l'élément de structure formant bouclier thermique comporte au moins un joint d'étanchéité à lèvre s'étendant vers l'extérieur du cadre, parallèlement au plan du panneau de remplissage, ce joint étant adapté à coopérer avec la lèvre similaire d'un joint homologue portée par le cadre d'un panneau de remplissage disposé dans un alvéole adjacent de l'ossature.According to another characteristic, the element of heat shield structure has at least one lip seal extending outward from frame, parallel to the plane of the filler panel, this seal being adapted to cooperate with the similar lip of a homologous seal carried by the frame of a panel filling placed in an adjacent cell of the frame.

Dans un autre mode de réalisation enfin, l'élément de structure formant bouclier thermique comporte vers l'intérieur du profilé une autre lèvre d'étanchéité, formant barrière d'arrêt pour un dépôt d'un mastic silicone ou autre, injecté entre le bouclier et le bord périphérique du panneau de remplissage.In another embodiment, finally, the element of heat shield structure has worms inside the profile another sealing lip, forming stop barrier for depositing a silicone sealant or other, injected between the shield and the peripheral edge filling panel.

D'autres caractéristiques d'un dispositif à rupture de pont thermique, établi conformément à l'invention, apparaítront encore à travers la description qui suit de plusieurs exemples de réalisation, donnés à titre indicatif et non limitatif, en référence aux dessins annexés sur lesquels :

  • La Figure 1 est une vue schématique en perspective d'une ossature de support pour façade du type à mur rideau, apte à recevoir des panneaux de remplissage dont le cadre est formé de profilés métalliques comportant un dispositif selon l'invention.
  • La Figure 2 est une vue en coupe transversale, à plus grande échelle, d'un premier mode de réalisation du dispositif selon l'invention, appliqué à un panneau de remplissage collé contre l'ossature de support.
  • La Figure 3 est une vue en coupe transversale, analogue à la Figure 2, mais appliquée à un panneau de remplissage maintenu contre l'ossature de support par une parclose externe.
  • La Figure 4 est une vue en coupe similaire à celle des Figures 2 et 3, selon une variante de réalisation.
Other characteristics of a thermal break device, established in accordance with the invention, will become apparent from the following description of several embodiments, given by way of non-limiting example, with reference to the appended drawings in which :
  • Figure 1 is a schematic perspective view of a support frame for facade of the curtain wall type, adapted to receive filler panels whose frame is formed of metal profiles comprising a device according to the invention.
  • Figure 2 is a cross-sectional view, on a larger scale, of a first embodiment of the device according to the invention, applied to a filling panel glued against the support frame.
  • Figure 3 is a cross-sectional view, similar to Figure 2, but applied to a filler panel held against the support frame by an external glazing bead.
  • Figure 4 is a sectional view similar to that of Figures 2 and 3, according to an alternative embodiment.

Sur la Figure 1, la référence 1 désigne le gros oeuvre d'un bâtiment ou analogue, très schématiquement illustré, contre lequel est appliquée vers l'extérieur de ce bâtiment une ossature de support 2 pour la façade de ce dernier.In Figure 1, the reference 1 designates the shell of a building or the like, very schematically illustrated, against which is applied to the outside of this building a support frame 2 for the front of the latter.

Cette ossature 2 comporte des montants verticaux 3 et des traverses horizontales 4, qui délimitent entre eux des alvéoles adjacents 5 dans le plan vertical de la façade, ces alvéoles étant destinés à recevoir des panneaux de remplissage 6, vitrés ou non, qui garnissent ainsi la façade en réalisant ce qu'il est convenu d'appeler dans la technique un mur rideau.This frame 2 has vertical uprights 3 and horizontal crosspieces 4, which delimit between them adjacent cells 5 in the vertical plane of the facade, these cells being intended to receive panels of filling 6, glazed or not, which thus fill the facade by realizing what is commonly called in the technical curtain wall.

Chaque panneau de remplissage 6 est de préférence entouré par un cadre métallique 7, destiné à venir se loger contre le fond de chaque alvéole dans l'ossature, les panneaux ainsi montés dans les alvéoles adjacents de cette dernière, étant pratiquement seuls visibles de l'extérieur de la façade.Each filling panel 6 is preferably surrounded by a metal frame 7, intended to be housed against the bottom of each cell in the frame, the panels thus mounted in the adjacent cells of the latter, being practically only visible from outside the facade.

Le cadre 7 de chaque panneau de remplissage est constitué au moyen de profilés métalliques qui entourent ce panneau selon ses quatre côtés consécutifs, ce cadre ou châssis de support du panneau étant ordinairement formé de quatre éléments qui se répartissent selon ces côtés en étant jointifs de l'un à l'autre dans les angles du panneau.The frame 7 of each filling panel is constituted by means of metal profiles which surround this panel according to its four consecutive sides, this frame or chassis of panel support usually being formed of four elements which are distributed along these sides by being joined from one to the other in the corners of the panel.

Compte tenu du matériau métallique, généralement de l'aluminium, qui forme les profilés du cadre, ceux-ci assurent une conduction thermique notable entre l'extérieur et l'intérieur de la façade de part et d'autre du panneau de remplissage qu'ils entourent.Given the metallic material, generally aluminum, which forms the frame profiles, these provide significant thermal conduction between the exterior and the interior of the facade on either side of the panel filling they surround.

L'invention a pour objet un dispositif qui permet de créer une rupture de pont thermique dans ces profilés.The subject of the invention is a device which makes it possible to create a thermal break in these profiles.

Dans l'exemple de réalisation illustré en coupe transversale sur la Figure 2, la référence 8 représente une traverse horizontale de l'ossature de support, délimitant de part et d'autre d'un élément central 9 avec des montants verticaux (non représentés), deux alvéoles adjacents 5 dans cette ossature.In the embodiment illustrated in section in Figure 2, reference 8 represents a horizontal cross member of the support frame, delimiting on either side of a central element 9 with uprights vertical (not shown), two adjacent cells 5 in this frame.

Chacun de ces alvéoles est prévu pour recevoir un panneau de remplissage 7, constitué dans cet exemple au moyen de deux parois vitrées 10 et 11, parallèles entre elles et séparées selon leur périphérie par un élément intercalaire 12.Each of these cells is designed to receive a panel filling 7, constituted in this example by means of two glass walls 10 and 11, parallel to each other and separated according to their periphery by an intermediate element 12.

Le panneau 7 est monté à l'intérieur d'un cadre 13 constitué au moyen d'un profilé métallique tubulaire 14, comportant une face verticale 15 parallèle au plan des parois vitrées et une face horizontale 16, perpendiculaire à la précédente et qui s'étend selon le bord latéral périphérique du panneau 7.The panel 7 is mounted inside a frame 13 constituted by means of a tubular metal profile 14, comprising a vertical face 15 parallel to the plane of the glass walls and a horizontal face 16, perpendicular to the previous one and which extends along the lateral edge panel device 7.

La face verticale 15 forme le fond d'un logement 17 dans lequel est montée et immobilisée une barrette de fixation 18, présentant une surface externe parallèle au plan du panneau, ce dernier étant collé contre la barrette par une couche 19 d'un matériau de collage convenable, selon la technique classique dite du « VEC » pour « Vitrage Extérieur Collé ».The vertical face 15 forms the bottom of a housing 17 in which is mounted and immobilized a fixing bar 18, having an external surface parallel to the plane of the panel, the latter being glued against the bar by a layer 19 of a suitable bonding material, according to the classic technique called "VEC" for "Glazing Glued Exterior ”.

Le panneau 7 s'appuie par son bord inférieur sur la figure contre la face horizontale 16 du profilé 14 du cadre 13 par l'intermédiaire d'une cale plane 20, le cas échéant maintenu entre la tranche du panneau et une plaque d'appui 21.The panel 7 is supported by its lower edge in the figure against the horizontal face 16 of the profile 14 of the frame 13 by via a flat block 20, if applicable held between the edge of the panel and a support plate 21.

Conformément à l'invention, cette face 16 du profilé 14 est aménagée de manière à comporter, s'étendant sous mais contre le panneau de remplissage 7, un élément de structure 22 constituant un bouclier thermique, réalisé de préférence en un matériau plastique isolant.According to the invention, this face 16 of the profile 14 is arranged to include, extending beneath but against the filling panel 7, a structural element 22 constituting a heat shield, preferably made made of an insulating plastic material.

Selon une caractéristique essentielle, ce bouclier thermique 22 est directement intégré au profilé 14 du cadre 13 et est aménagé de manière à envelopper étroitement la périphérie extérieure du panneau de remplissage 7. Il permet ainsi de reprendre, par l'intermédiaire de la cale 20 et de la plaque d'appui 21, le poids de ce panneau.According to an essential characteristic, this shield thermal 22 is directly integrated into profile 14 of the frame 13 and is arranged so as to tightly envelop the outer periphery of the filling panel 7. It thus allows to resume, via the wedge 20 and the support plate 21, the weight of this panel.

Le bouclier thermique 22 est avantageusement muni d'au moins une rainure 23 pour l'immobilisation dans celle-ci du talon 24 d'un joint d'étanchéité comportant une lèvre 25, s'étendant vers l'extérieur, sensiblement dans le plan du panneau 7, cette lèvre étant prévue pour coopérer avec une lèvre homologue 26 portée par le bouclier thermique 22a, identique au bouclier 22 et associé au cadre 13a qui supporte le panneau de remplissage 7a de l'alvéole voisin dans l'ossature, la coopération mutuelle des lèvres 25 et 26 isolant de l'extérieur la région 27 qui sépare les deux cadres 13 et 13a de ces panneaux 7 et 7a.The heat shield 22 is advantageously provided with minus a groove 23 for immobilization therein of heel 24 of a seal comprising a lip 25, extending outward, substantially in the plane of the panel 7, this lip being designed to cooperate with a homologous lip 26 carried by the heat shield 22a, identical to shield 22 and associated with frame 13a which supports the filling panel 7a of the neighboring cell in the framework, the mutual cooperation of the lips 25 and 26 isolating from the outside the region 27 which separates the two frames 13 and 13a of these panels 7 and 7a.

Le cas échéant, la face horizontale 16 de chaque profilé 14 peut comporter elle-même une rainure 28, analogue à la rainure 23, dans laquelle est monté un autre joint 29 à lèvre 30, qui, avec le même joint 31 de l'autre profilé 14a, permet de parfaire l'étanchéité et l'isolation de la région 27.Where appropriate, the horizontal face 16 of each profile 14 may itself have a groove 28, similar to the groove 23, in which is mounted another seal 29 to lip 30, which, with the same seal 31 on the other profile 14a, makes it possible to perfect the sealing and the insulation of the region 27.

Un bloc de mastic ou analogue 32 est avantageusement injecté entre le panneau de remplissage 7 et l'extrémité 33 du bouclier 22 opposée au profilé métallique 14, afin en particulier d'éviter des entrées d'eau ou autres sous le panneau vers l'intérieur du bâtiment, de l'autre côté de la façade.A block of putty or the like 32 is advantageously injected between the filling panel 7 and the end 33 of the shield 22 opposite the metal profile 14, so as to particular to avoid water or other entry under the sign towards the interior of the building, on the other side of the facade.

La Figure 3 illustre une variante de réalisation dans laquelle on retrouve les panneaux de remplissage 7 et 7a avec leurs cadres 13 et 13a formés de profilés métalliques tubulaires 14 et 14a.Figure 3 illustrates an alternative embodiment in which we find the filling panels 7 and 7a with their frames 13 and 13a formed from metal profiles tubular 14 and 14a.

Comme précédemment, chaque profilé comporte une face horizontale 16 dans laquelle est monté un élément de structure 22 formant bouclier thermique, celui-ci comportant un joint d'étanchéité 24 avec une lèvre 25 pour isoler la région 27.As before, each profile has one side horizontal 16 in which is mounted an element of structure 22 forming a heat shield, this comprising a seal 24 with a lip 25 for isolate region 27.

Dans cette variante, chaque panneau 7 est immobilisé vis-à-vis de son cadre 13, en disposant dans le logement 17, non plus une barrette de collage, mais un joint 34, muni de plusieurs lèvres telles que 35 qui viennent en appui contre la paroi vitrée 10 dans le fond de l'alvéole 5 qui reçoit le panneau, celui-ci étant maintenu en place au moyen d'une parclose 36, immobilisée à la manière d'un clip ou autre vis-à-vis du bouclier 22, cette parclose présentant un retour plan 37 parallèle au panneau 7, muni à son extrémité d'un autre joint 38, le panneau étant ainsi serré entre les joints 34 et 37.In this variant, each panel 7 is immobilized with respect to of its frame 13, by placing in the housing 17, not plus a bonding bar, but a seal 34, provided with several lips such as 35 which bear against the glass wall 10 in the bottom of the cell 5 which receives the panel, which is held in place by means of a glazing bead 36, immobilized like a clip or other vis-à-vis the shield 22, this glazing bead having a back plane 37 parallel to panel 7, provided at its end another seal 38, the panel thus being clamped between the seals 34 and 37.

Dans la variante illustrée sur la figure 4, où le panneau 7 est à nouveau immobilisé dans le fond de son alvéole 5 par une barrette 18 et un matériau de collage 19 comme dans l'exemple représenté sur la figure 2, le bouclier 22 est directement réalisé de manière à comporter, venues de fabrication des lèvres sur ses faces latérales opposées, l'une jouant le rôle de la lèvre 25 décrite dans les variantes précédentes, l'autre repérée 39, formant barrière d'étanchéité pour le bloc de mastic 32 prévu entre le bouclier thermique et le bord périphérique inférieur du panneau 7.In the variant illustrated in Figure 4, where the panel 7 is again immobilized in the bottom of its cell 5 by a bar 18 and a bonding material 19 as in the example shown in Figure 2, the shield 22 is directly produced so as to include, coming from manufacture of the lips on its opposite lateral faces, one playing the role of the lip 25 described in the previous variants, the other marked 39, forming a barrier seal for the putty block 32 provided between the heat shield and the lower peripheral edge of the panel 7.

Dans les exemples décrits ci-dessus, le bouclier thermique 22 est serti vis-à-vis de la face inférieure 16 du profilé 14 qui le supporte. Dans d'autres modes de réalisation, ce bouclier peut être immobilisé différemment et en particulier par un clip ou analogue (non représenté).In the examples described above, the heat shield 22 is crimped with respect to the underside 16 of the profile 14 who supports it. In other embodiments, this shield can be immobilized differently and in in particular by a clip or the like (not shown).

On réalise ainsi un dispositif de rupture de pont thermique de conception simple, l'intégration du bouclier au profilé lui-même de manière à ce qu'il entoure le panneau de remplissage se révélant d'une grande efficacité, en évitant les difficultés de mise en oeuvre de la solution classique à barrettes isolantes dans un profilé métallique en deux parties.A thermal break device is thus produced simple design, integration of the shield into the profile itself so that it surrounds the panel of filling proving to be very effective, avoiding the difficulties of implementing the conventional solution to insulating strips in a metal profile in two parts.

Bien entendu, il va de soi que l'invention ne se limite pas à l'exemple de réalisation plus spécialement décrit ci-dessus en référence aux dessins annexés ; elle en embrasse au contraire toutes les variantes.Of course, it goes without saying that the invention is not limited to the embodiment more specifically described above with reference to the accompanying drawings; she embraces it on the contrary all the variants.
