Description

La présente invention se rapporte au domaine des moyens de fixation et concerne plus particulièrement un système de fixation de panneaux de matériau fragile à une structure porteuse au moyen d'attaches ponctuelles.The present invention relates to the field of fixing means and relates more particularly to a system for fastening panels of fragile material to a bearing structure by means of point fasteners.

Notamment dans le domaine de la fixation de vitrages sur des structures porteuses de bâtiment, il existe de nombreux systèmes de fixation ponctuelle destinés à préserver un maximum de visibilité à travers le vitrage, grâce à des attaches ponctuelles n'occupant qu'une très faible superficie du vitrage. Ainsi, on a proposé des systèmes de fixation ponctuelle avec des attaches qui maintiennent celui-ci par serrage sur les deux faces du panneau de verre, le cas échéant de part et d'autre d'un perçage traversant. De tels systèmes sont décrits notamment dans les documents FR-A-2 739 406 et DE-A-195 14 818 .Particularly in the field of glazing fixing on building load bearing structures, there are numerous point fixing systems designed to preserve maximum visibility through the glazing, thanks to point fasteners occupying only a very small area. glazing. Thus, it has been proposed point fastening systems with fasteners that hold it by clamping on both sides of the glass panel, where appropriate on both sides of a through hole. Such systems are described in particular in the documents FR-A-2,739,406 and DE-A-195 14 818 .

Ces systèmes apportent une solution adaptée au problème de la fixation d'un panneau dans un plan sensiblement coplanaire à la structure porteuse mais n'offrent pas une solution optimale lorsqu'il s'agit d'immobiliser le panneau dans le plan de la structure porteuse. En effet, les systèmes de fixation connus de l'art antérieur sont positionnés selon une direction sensiblement perpendiculaire au plan du panneau, générant de ce fait un espace supplémentaire entre la structure porteuse et le plan du panneau pour leur implantation, cette implantation en saillie par rapport au plan du panneau induisant un moment qui nuit à la pérennité de la fixation.These systems provide a solution adapted to the problem of fixing a panel in a plane substantially coplanar with the supporting structure but do not offer an optimal solution when it comes to immobilize the panel in the plane of the supporting structure . Indeed, the fastening systems known from the prior art are positioned in a direction substantially perpendicular to the plane of the panel, thereby generating an additional space between the bearing structure and the plane of the panel for their implantation, this projecting implantation by relation to the plane of the panel inducing a moment that harms the durability of the fixation.

Tout cela implique un coût notable qui risque de limiter la mise en oeuvre de ces systèmes à des réalisations de prestige.All this entails a significant cost which risks limiting the implementation of these systems to prestigious achievements.

Le but de la présente invention est de proposer un système de fixation ponctuelle simple mais toujours satisfaisant du point de vue des exigences esthétiques et qui s'inscrive sensiblement dans le plan du panneau.The object of the present invention is to provide a simple point fixing system but still satisfactory from the point of view of aesthetic requirements and which fits substantially in the plane of the panel.

A cet effet, l'invention a pour objet un système de fixation d'un panneau de matériau fragile à une structure porteuse, comprenant au moins une attache ponctuelle en prise avec au moins une première zone de contact réalisée dans le panneau, qui se caractérise en ce que ladite attache ponctuelle comporte une première partie d'ancrage au niveau d'une première zone de contact et une deuxième partie d'ancrage au niveau d'une deuxième zone de contact, les première et deuxième parties d'ancrage étant d'une part, reliées par au moins un dispositif de réglage adapté pour mettre en appui les première et deuxième parties d'ancrage contre respectivement les premier et deuxième zones de contact et d'autre part, situées dans le plan du panneau.For this purpose, the subject of the invention is a system for fastening a panel of fragile material to a supporting structure, comprising at least one point fastener in engagement with at least one first contact zone made in the panel, which is characterized in that said point fastener comprises a first anchoring portion at a first contact area and a second anchoring portion at a second contact area, the first and second anchoring portions being on the one hand, connected by at least one adjusting device adapted to bear the first and second anchoring parts against respectively the first and second contact areas and on the other hand, located in the plane of the panel.

Grâce à ce système de fixation, les efforts résultant de la fixation du panneau à la structure porteuse sont dirigés dans le plan du panneau et sensiblement dans son prolongement, n'induisant pas ainsi d'épaisseur supplémentaire entre le panneau et la structure porteuse..With this fastening system, the forces resulting from the fixing of the panel to the supporting structure are directed in the plane of the panel and substantially in its extension, thus not inducing additional thickness between the panel and the supporting structure.

L'invention est ainsi adaptée à la fixation de panneaux de verre de tous types: monolithique, feuilleté, ou multiple avec des feuilles de verre éventuellement feuilleté séparées par des lames d'air ou autre gaz, le verre n'étant pas nécessairement trempé, ou le cas échéant avec des exigences moins drastiques concernant la trempe.The invention is thus adapted to the fixing of glass panels of all types: monolithic, laminated, or multiple with optionally laminated glass sheets separated by blades of air or other gas, the glass not being necessarily tempered, or if necessary with less stringent quenching requirements.

La présence de dispositif de réglage permet d'induire dans le plan des panneaux des contraintes en compression qui s'opposeront aux efforts mécaniques, notamment de traction, lors de la fixation dudit panneau à la structure porteuse, ou à un autre panneau.The presence of adjustment device makes it possible to induce in the plane of the panels compressive stresses which will oppose the mechanical stresses, in particular traction forces, during the fixing of said panel to the supporting structure, or to another panel.

La figure 1 présente un écran ou plus communément appelé « écran diffuseur » dans ce domaine technique, composé d'au moins un panneau de verre 1, ce panneau de verre étant destiné à être suspendu à une structure porteuse à l'aide d'au moins un système de fixation 2 selon l'invention.The figure 1 has a screen or more commonly called "diffuser screen" in this technical field, consisting of at least one glass panel 1, this glass panel being intended to be suspended from a support structure using at least one system fixing 2 according to the invention.

Sur l'exemple représenté en figure 1, on compte quatre systèmes de fixation 2 par panneau 1, agissant respectivement dans chaque coin du panneau. Il est bien entendu que le nombre et l'emplacement des systèmes de fixation sur le panneau peuvent être modifiés en fonction des souhaits architecturaux.In the example shown in figure 1 there are four fastening systems 2 per panel 1, respectively acting in each corner of the panel. It is understood that the number and location of the fastening systems on the panel can be modified according to the architectural wishes.

Pour des surfaces vitrées de grande étendue comprenant un grand nombre de panneaux de verre juxtaposés, deux ou plusieurs attaches ponctuelles voisines peuvent être fixées à la structure par l'intermédiaire d'une pièce de liaison à deux ou plusieurs bras.For large glazed surfaces comprising a large number of juxtaposed glass panels, two or more adjacent point fasteners can be attached to the structure via a connecting piece with two or more arms.

La partie centrale 9, 10 de chaque cavalier prend appui au droit de chacun des première et deuxième zones de contact 3, 4 au niveau respectivement de première et deuxièmes parties d'ancrage, tandis que chacune des parties latérales 11, 12, 13, 14 de chacun des cavaliers positionnées d'un même côté du panneau sont reliées entre-elles par des dispositifs de réglage 15, 16, qui sont adaptés pour rapprocher les parties centrales 9, 10 des cavaliers ou sein des zones de contact 3,4.Each of the riders (represented in section at the level of the figure 3 ) comprises a central portion 9, 10 and two lateral portions 11, 12, 13, 14. The central portion 9, 10 of each rider bears on the right of each of the first and second contact zones 3, 4 respectively at first and second anchoring portions, while each of the side portions 11, 12, 13, 14 of each of the jumpers positioned on the same side of the panel are interconnected by adjusting devices 15, 16, which are adapted for bring the central parts 9, 10 of the jumpers or within the contact zones 3,4.

Dans l'exemple de réalisation représenté en figure 3, le dispositif de réglage est un dispositif de mise en tension qui est constitué d'un système vis-écrou, la partie faisant office d'écrou étant par exemple constituée par une bague, munie d'un taraudage sur sa paroi interne, cette bague étant montée glissante sur l'une partie latérale du cavalier, la partie faisant office écrou étant par exemple constituée par une extrémité filetée de la partie latérale du second cavalier positionnée du même côté du panneau.In the embodiment shown in figure 3 , the adjustment device is a tensioning device which consists of a screw-nut system, the part serving as a nut being for example constituted by a ring, provided with a tapping on its inner wall, this ring being slidably mounted on the a side portion of the jumper, the nut portion being constituted for example by a threaded end of the side portion of the second jumper positioned on the same side of the panel.

En rapprochant les attaches ponctuelles l'une vers l'autre grâce aux dispositifs de réglage 15, 16, il est possible d'induire dans la zone du panneau en regard des parties ancrage, des contraintes de compression, qui pourront s'opposer à celles qui seront générées lors de l'accrochage du panneau à la structure porteuse.By bringing the point fasteners closer to each other thanks to the adjustment devices 15, 16, it is possible to induce, in the zone of the panel opposite the anchoring parts, compressive stresses, which may be opposed to those which will be generated during the attachment of the panel to the supporting structure.

Bien entendu, en fonction de la masse du panneau, de la nature du matériau constituant le panneau, de l'intensité des contraintes induites, on adaptera le matériau formant les attaches ponctuelles. On pourra ainsi choisir des matériaux plastiques, composites.Of course, depending on the mass of the panel, the nature of the material constituting the panel, the intensity of the induced stresses, one will adapt the material forming the point fasteners. It will be possible to choose plastic materials, composites.

De même, selon une variante non représentée sur les figures, on pourra adjoindre aux dispositifs de réglage 15, 16, un dispositif limiteur de couple, notamment à friction par exemple.Similarly, according to a variant not shown in the figures, may be added to the adjustment devices 15, 16, a torque limiting device, including friction for example.

Sur les figures 3 et 4, on a représenté une autre variante de réalisation de l'invention. Celle-ci se distingue de celle représentée en figure 2 par le fait que l'une des zones de contact (la première ou la seconde) ne se situe pas sur la périphérie du panneau mais dans une partie déportée du bord.On the figures 3 and 4 another alternative embodiment of the invention is shown. This is different from that represented in figure 2 in that one of the contact areas (the first or second) is not located on the periphery of the panel but in a remote part of the edge.

Par ailleurs, sur la figure 4, on peut remarquer que les attaches ponctuelles du système de fixation 2 ne prennent pas appui directement sur le chant du panneau au niveau d'une zone de contact, mais au niveau d'une couche intercalaire 17.Moreover, on the figure 4 it may be noted that the point fasteners of the fastening system 2 do not bear directly on the edge of the panel at a contact zone, but at an intermediate layer 17.

La couche intermédiaire 17 comprend un élément intercalaire disposé au voisinage de la zone d'appui et éventuellement un matériau adhésif déposé sur l'élément intercalaire.The intermediate layer 17 comprises an intermediate element disposed in the vicinity of the bearing zone and optionally an adhesive material deposited on the intermediate element.

L'élément intercalaire est une plaque rigide, de préférence transparente, par exemple en polycarbonate ou en silicone dur ayant une dureté Shore D de l'ordre d'au moins 70 à 75.The intermediate element is a rigid plate, preferably transparent, for example polycarbonate or hard silicone having a Shore D hardness of the order of at least 70 to 75.

La colle est avantageusement également transparente, notamment à base d'un matériau silicone ou acrylique réticulable par UV.The glue is advantageously also transparent, especially based on a silicone or acrylic material crosslinkable by UV.

Grâce à la présence de l'élément intercalaire rigide, la colle peut être relativement souple, de dureté inférieure à celle de l'élément intercalaire. Ainsi, un matériau adhésif ayant à l'état durci une dureté Shore A de l'ordre de 30 à 35, par exemple de type silicone, permet de réaliser une jonction adhésive efficace entre l'élément intercalaire et le panneau de verre, alors que l'élément intercalaire confère la rigidité nécessaire à la couche intermédiaire 17.Due to the presence of the rigid intermediate element, the adhesive can be relatively flexible, of lower hardness than that of the intermediate element. Thus, an adhesive material having in the cured state a Shore A hardness of the order of 30 to 35, for example of the silicone type, makes it possible to form an effective adhesive junction between the intermediate element and the glass panel, whereas the intermediate element confers the necessary rigidity on the intermediate layer 17.

Une fois le matériau adhésif durci, la couche intermédiaire 17 permet une transmission intégrale du poids du panneau à la structure sans risque d'écrasement de la couche dans le temps grâce à l'élément intercalaire rigide.Once the adhesive material has hardened, the intermediate layer 17 allows an integral transmission of the weight of the panel to the structure without risk of crushing the layer over time through the rigid intermediate element.

Dans la variante de réalisation représentée en figure 3, la zone de contact déportée de la périphérie du panneau comporte une virole 18, réalisée dans un matériau métallique. Cette virole en prenant appui au niveau des parois de la zone de contact permet de renforcer mécaniquement les parois de la zone de contact et par voie de conséquence de supporter des forces induites par le système de fixation plus importantes.In the variant embodiment shown in figure 3 , the remote contact zone of the periphery of the panel comprises a ferrule 18, made of a metallic material. This shell bearing support at the walls of the contact zone makes it possible to mechanically strengthen the walls of the contact zone and consequently to withstand forces induced by the larger fastening system.

En variante, non représentée sur les figures, cette virole 18 est pourvue d'une articulation pour permettre la transmission de mouvements relatifs éventuels lors du montage du panneau et/ou sous l'effet de charge localisés (poids de dépôt de neige) ou de dilatation thermique du panneau.As a variant, not shown in the figures, this collar 18 is provided with a hinge to allow the transmission of any relative movements during assembly of the panel and / or under the effect of localized loads (weight of snow deposit) or thermal expansion of the panel.

Dans ce mode de réalisation non représenté, l'articulation est constituée par une rotule ou par tout autre système d'articulation équivalente, qui permet de préférence une amplitude de mouvement d'au moins 5° d'angle dans chaque direction.In this embodiment not shown, the joint is constituted by a ball joint or any other equivalent articulation system, which preferably allows an amplitude of movement of at least 5 ° angle in each direction.

Le système de fixation 2 selon l'invention fournit une solution performante qui ne nécessite pas de façonnage particulier du panneau de verre, les zones de contact étant des usinages aisément réalisables.The fastening system 2 according to the invention provides a powerful solution that does not require special shaping of the glass panel, the contact areas being easily achievable machining.

En choisissant avantageusement des matériaux transparents pour former la couche intermédiaire, et éventuellement le système de fixation, la solution de fixation obtenue satisfait les exigences esthétiques de transparence maximale souvent posées par les architectes.By choosing advantageously transparent materials to form the intermediate layer, and possibly the fastening system, the fixing solution obtained satisfies the aesthetic requirements of maximum transparency often asked by the architects.

La description détaillée de l'invention vient d'être faite dans le cas de réalisations particulières d'écran, auxquelles l'invention n'est pas limitée.The detailed description of the invention has just been made in the case of particular screen embodiments, to which the invention is not limited.

Enfin, les panneaux à fixer peuvent être des vitrages aussi bien monolithiques, feuilletés, mixtes, décorés, mais aussi des panneaux d'affichages ou encore des panneaux de matériau fragile naturels tels que de la pierre, du marbre, ou synthétiques.Finally, the panels to be fixed can be monolithic glazings, laminated, mixed, decorated, but also display panels or panels of fragile natural material such as stone, marble, or synthetic.

Grâce à ce système de fixation, il est possible de relier entre eux au moins deux panneaux, ou au moins un panneau à une structure porteuse, ces panneaux pouvant avoir des mouvements relatifs entre eux (pivotement, coulissement) ou bien encore de réaliser des fonctions d'ouvrant, de dormant.With this fastening system, it is possible to connect at least two panels, or at least one panel to a supporting structure, these panels can have relative movements between them (pivoting, sliding) or to perform functions opening, sleeping.
