Description

La présente invention concerne un dispositif de fixation pour plaques, en particulier pour plaques de substrat verrier, comprenant des éléments de retenue disposés entre chaque substrat et une structure porteuse en vue de transférer les charges des substrats à la structure porteuse, lesquels éléments de retenue comprennent des moyens pour limiter les variations ou les écarts dimensionnels, les déformations et les déplacements entre les substrats et la structure porteuse.The present invention relates to a plate fastening device, in particular for glass substrate plates, comprising retaining elements arranged between each substrate and a carrier structure for transferring the charges from the substrates to the supporting structure, which retaining elements comprise means for limiting variations or dimensional deviations, deformations and displacements between the substrates and the carrier structure.

Lors de l'élaboration de façade en verre pour bâtiments tertiaires ou à vocation domestique, on connaît de nombreuses techniques mettant en oeuvre des éléments de retenue ou de fixation ponctuels qui ne soutiennent les vitrages, par exemple dans un revêtement de façade, que sur une petite surface, qui permettent la réalisation de constructions largement transparentes.In the development of glass facades for commercial or domestic buildings, numerous techniques are known using point retention or fixing elements which support the glazings, for example in a facade covering, only on a single surface. small surface, which allow the realization of largely transparent constructions.

Ainsi, il existe par exemple connu par DE29622665U ou EP0698717A1 des systèmes qui soutiennent les substrats par paires au niveau de leur cordon de joint périphérique qui les séparent ou des éléments de retenue qui traversent des perçages pratiqués dans les substrats.Thus, there exists for example known by DE29622665U or EP0698717A1 systems that support the substrates in pairs at their peripheral seal bead separating them or retaining elements that pass through bores in the substrates.

Pour la sécurité des façades en verre, différentes charges revêtent de l'importance. Il y a d'une part les charges extérieures (poids du verre lui- même, vent, précipitations, chocs, etc.) et d'autre part celles qui résultent de sollicitations par contraintes à la suite par exemple de variations de température, des tolérances dans la structure porteuse et des erreurs de montage, par exemple.For the safety of glass facades, different loads are important. On the one hand there are external loads (weight of the glass itself, wind, precipitation, shocks, etc.) and on the other hand those resulting from stresses due to, for example, temperature variations, tolerances in the carrier structure and mounting errors, for example.

En outre, il est connu qu'un substrat verrier est fragile et ne supporte, contrairement aux matériaux ductiles (les métaux ou les matières plastiques, par exemple), que des déformations élastiques et aucune déformation plastique.In addition, it is known that a glass substrate is fragile and supports, unlike ductile materials (metals or plastics, for example), that elastic deformations and no plastic deformation.

Par principe, le substrat verrier doit donc être soumis à des sollicitations mécaniques minimales lors du transfert de charges s'exerçant par l'intermédiaire de celui-ci à la structure porteuse.In principle, the glass substrate must therefore be subjected to minimal mechanical stresses when transferring charges exerted through it to the carrier structure.

Ainsi, lorsqu'il convient de concevoir des façades mécaniquement résistantes, ces façades étant obtenues par la juxtaposition d'une pluralité de substrats verriers, le concepteur dispose de plusieurs solutions :

  • une première des solutions consiste à sur-dimensionner les substrats verriers, ce sur-dimensionnement étant généralement réalisé au niveau de l'épaisseur du substrat. Le principal inconvénient de cette solution réside dans le fait qu'elle conduit à une augmentation des masses, ce qui implique indubitablement à un sur-dimensionnement des éléments de retenue et à un renforcement de la structure porteuse.
  • une deuxième solution consiste non pas à sur-dimensionner les substrats verriers mais à admettre entre eux et la structure porteuse des éléments de retenue intégrant des degrés de liberté (en translation, en rotation, combinaison des deux) permettant d'induire des déplacements entre les substrats et la structure porteuse sans mise en contrainte des substrats.
Thus, when it is advisable to design mechanically resistant facades, these facades being obtained by the juxtaposition of a plurality of glass substrates, the designer has several solutions:
  • a first of the solutions consists of over-sizing the glass substrates, this over-sizing being generally performed at the thickness of the substrate. The main disadvantage of this solution lies in the fact that it leads to an increase in mass, which undoubtedly implies over-sizing of the retaining elements and a strengthening of the supporting structure.
  • a second solution is not to over-size the glass substrates but to admit between them and the support structure retaining elements incorporating degrees of freedom (in translation, rotation, combination of the two) to induce movement between the substrates and the carrier structure without stressing the substrates.

Cette deuxième solution donne entière satisfaction tant qu'il convient de rattraper des tolérances dimensionnelles entre les substrats ou de transmettre à la structure porteuse des efforts issus de charges extérieures (vent par exemple) mais elle est inopérante quand il s'agit de contrecarrer des efforts résultant de variation de température du fluide gazeux emprisonné entre les deux substrats. En effet, toute variation de température dans un sens d'une augmentation ou d'une diminution de température induit des variations du volume ou de pression du fluide emprisonné et génère des phénomènes de gonflement ou au contraire des phénomènes de striction entre les substrats qui peuvent engendrer contraintes au niveau des substrats qui dépassent les limites mécaniques admissibles risquant de ce fait d'entraîner des ruptures.This second solution is entirely satisfactory as long as it is necessary to make up dimensional tolerances between the substrates or to transmit to the load-bearing structure forces coming from external loads (wind for example) but it is inoperative when it comes to thwarting efforts. resulting from temperature variation of the gaseous fluid trapped between the two substrates. Indeed, any variation in temperature in a direction of an increase or decrease in temperature induces variations in the volume or pressure of the trapped fluid and generates swelling phenomena or on the contrary necking phenomena between the substrates which can to generate stresses at the level of the substrates which exceed the admissible mechanical limits risking thereby to cause breaks.

La présente invention vise donc à pallier ces inconvénients en proposant des perfectionnements apportés aux éléments de retenue entre les substrats et la structure porteuse qui limitent les effets de variation de l'état thermodynamique du fluide emprisonné entre les substrats.The present invention therefore aims to overcome these disadvantages by proposing improvements made to the retaining elements between the substrates and the carrier structure which limit the effects of variation of the thermodynamic state of the fluid trapped between the substrates.

A cet effet le dispositif de fixation objet de l'invention, pour deux substrats, est defini par les caractéristiques de la revendication 1.For this purpose the fixing device according to the invention, for two substrates, is defined by the features of claim 1.

Selon un autre aspect de l'invention, celle-ci vise un ensemble de construction constitué par la juxtaposition de plusieurs substrats assemblés à l'aide du dispositif précédemment décrit.According to another aspect of the invention, it relates to a building assembly consisting of the juxtaposition of several substrates assembled using the device described above.

L'invention sera maintenant décrite plus en détails à l'aide d'exemples non limitatifs et de figures :

  • la figure 1 est une vue en coupe et en élévation latérale du dispositif objet de l'invention,
  • la figure 2 est vue du dispositif selon l'invention en éclaté,
The invention will now be described in more detail using non-limiting examples and figures:
  • the figure 1 is a view in section and in side elevation of the device which is the subject of the invention,
  • the figure 2 is seen from the device according to the invention exploded,

Si l'on se réfère tout d'abord à la figure 1, on peut voir que l'on a représenté par 1 et 2 deux substrats, sensiblement transparents, notamment en verre trempé qui sont destinés par exemple à constituer lorsqu'ils sont assemblés entre eux par des moyens connus que l'on ne détaillera pas dans cette présente demande, un substrat un vitrage multiple (double vitrage par exemple).If we first refer to the figure 1 , it can be seen that there are represented by 1 and 2 two substrates, substantially transparent, especially tempered glass which are intended for example to constitute when they are assembled together by known means that will not be detailed in this present application, a substrate a multiple glazing (double glazing for example).

De tels vitrages multiples, lorsqu'ils sont juxtaposés, forment des façades transparentes et dont le maintien à une structure porteuse est assuré par une pluralité d'éléments de retenue repérés 3 sur la figure 1.Such multiple glazings, when juxtaposed, form transparent facades and whose maintenance to a supporting structure is provided by a plurality of retaining elements marked 3 on the figure 1 .

Comme on peut le voir encore sur la figure 1, l'élément de retenue 3 est en fait constituer par l'assemblage d'une pluralité d'éléments.As can be seen again on the figure 1 , the retaining element 3 is actually constituted by the assembly of a plurality of elements.

Ainsi, l'élément de retenue 3 comporte un premier élément 4, obtenu à partir d'un profilé en matériau métallique ou plastique et de section droite de profil varié, notamment circulaire dont l'une des extrémités libres est pourvue d'un moyen de connexion avec un insert 5, ce moyen de connexion pouvant être un filetage, un montage à baïonnette ou tout autre système équivalent.Thus, the retaining element 3 comprises a first element 4, obtained from a section of metal or plastic material and of cross-section of varied profile, in particular circular, one of whose free ends is provided with a means of connection with an insert 5, the connection means may be a thread, a bayonet mount or any other equivalent system.

Cet insert 5 qui sera décrit plus en détail ci-après est destiné à être enfoncé au niveau d'un trou 6 borgne, dont l'un seulement peut être vu sur la Figure 1. Bien entendu, en fonction des applications visées, les trous peuvent être débouchants, circulaires, oblongs..This insert 5 which will be described in more detail below is intended to be depressed at a blind hole 6, only one of which can be seen on the Figure 1 . Of course, depending on the intended applications, the holes may be open, circular, oblong ..

Chacun de ces trous 6 est délimité par un fond plat, et par une paroi latérale raccordée au fond par une région de profil courbe et de rétention, notamment concave, de concavité tournée vers l'intérieur du trou 6 et présentant une symétrie axiale.Each of these holes 6 is delimited by a flat bottom, and by a side wall connected to the bottom by a region of curved profile and retention, in particular concave, of concavity facing the inside of the hole 6 and having axial symmetry.

La profondeur des trous 6, au niveau des fonds 3, correspond par exemple au plus à la moitié de l'épaisseur de la plaque 1.The depth of the holes 6 at the bottom 3, for example corresponds to at most half the thickness of the plate 1.

Dans chacun des trous 6 est introduit un insert 5 venu de moulage dans une matière plastique telle que du PVDF par exemple (polyfluorure de vinylidène), ou dans une matière métallique (aluminium par exemple). En variante, cet insert peut être moulé in situ. Cet insert est soit monobloc, soit composé de plusieurs éléments. Il est déformable élastiquement, voire plastiquement de manière à permettre son introduction dans le trou.In each of the holes 6 is introduced an insert 5 molded in a plastic material such as PVDF for example (polyvinylidene fluoride), or in a metal material (aluminum for example). Alternatively, this insert can be molded in situ. This insert is either monobloc or composed of several elements. It is elastically deformable, or plastically so as to allow its introduction into the hole.

L'insert 5 comporte une pluralité d'entailles radiales régulièrement espacées et relativement profondes, s'étendant jusqu'au voisinage du fond 10, qui peut être éventuellement percé.The insert 5 has a plurality of regularly spaced and relatively deep radial notches, extending to the vicinity of the bottom 10, which can be optionally drilled.

Par ces entailles, la paroi latérale de l'insert 5 se trouve ainsi divisée en « pétales », lesquels donnent à l'insert une flexibilité, les « pétales » pouvant ainsi fléchir vers l'intérieur pour permettre l'introduction par déformation élastique, voire plastique, de l'insert 5 dans un trou 6 ; une fois l'insert 5 introduit, les pétales reviennent à leur position initiale, épousant la surface externe du trou. L'accrochage de l'insert 5 sous le bourrelet précité est ainsi réalisé.By these cuts, the side wall of the insert 5 is thus divided into "petals", which give the insert a flexibility, the "petals" can thus bend inward to allow introduction by elastic deformation, even plastic, of the insert 5 in a hole 6; once the insert 5 is introduced, the petals return to their initial position, conforming to the external surface of the hole. The attachment of the insert 5 under the aforementioned bead is thus achieved.

L'autre extrémité libre du premier élément 4 est destiné à coulisser ou glisser librement au sein d'un deuxième élément constituant l'élément de retenue 3.The other free end of the first element 4 is intended to slide or slide freely within a second element constituting the retaining element 3.

Sur la figure 1 ce deuxième élément 7 est en fait constituer par une pièce venue de moulage ou d'usinage d'une matière plastique ou métallique et est de forme globalement tronconique.On the figure 1 this second element 7 is actually constituted by a molded piece or machining a plastic or metal material and is generally frustoconical shape.

Selon une caractéristique de ce deuxième élément 7, l'une de ses dimensions caractéristiques (en fait son épaisseur) est inférieure à la distance de l'espace interne du double vitrage.According to a characteristic of this second element 7, one of its characteristic dimensions (in fact its thickness) is less than the distance of the internal space of the double glazing.

Ce deuxième élément 7 comporte sensiblement deux alésages coaxiaux à son axe principal de manière à délimiter un premier orifice 8 dans lequel peut coulisser (c'est-à-dire autoriser un mouvement relatif de translation) le premier élément 4 puis dans le prolongement de ce premier orifice 8, un deuxième orifice 9 délimitant une cavité dans laquelle peut coopérer des moyens de compensation des variations dimensionnelles dont le fonctionnement et la structure seront détaillés ci-après.This second element 7 comprises substantially two bores coaxial with its main axis so as to define a first orifice 8 in which can slide (that is to say allow a relative translational movement) the first element 4 and then in the extension of this first orifice 8, a second orifice 9 delimiting a cavity in which can cooperate means for compensation of dimensional variations whose operation and structure will be detailed below.

Selon une première variante de réalisation, on prévoit de disposer entre les deux orifices 8, 9 réalisés dans ce deuxième élément, un troisième alésage délimitant entre les deux orifices d'extrémité une cavité 10 apte à recevoir une partie en saillie 11 réalisée sous la forme d'un épaulement à l'autre extrémité libre du premier élément 4, cette partie en saillie permettant d'introduire dans la cinématique liant le premier élément 4 au deuxième élément 7 une butée en translation.According to a first embodiment, provision is made to arrange between the two orifices 8, 9 made in this second element, a third bore delimiting between the two end holes a cavity 10 adapted to receive a projecting portion 11 made in the form a shoulder at the other free end of the first element 4, this projecting portion for introducing into the kinematic linking the first element 4 to the second element 7 a stop in translation.

Selon une deuxième variante de réalisation, la butée en translation entre le premier élément 4 et le deuxième élément 7 est réalisée par une goupille qui traverse radialement à la fois le premier élément 4 et le deuxième élément 7, le jeu ou le débattement axiale étant obtenu par les dimensions respectives des orifices pratiqués (en fait l'un des orifices par exemple celui qui est réalisé dans le premier élément 4 est circulaire, tandis que celui qui est réalisé radialement dans le second élément est oblong de manière à permettre un déplacement de la goupille liant les deux pièces).According to a second variant embodiment, the abutment in translation between the first element 4 and the second element 7 is formed by a pin which passes radially through both the first element 4 and the second element 7, the clearance or the axial displacement being obtained by the respective dimensions of the orifices made (in fact one of the orifices for example that which is made in the first element 4 is circular, whereas the one which is made radially in the second element is oblong so as to allow a displacement of the pin binding the two pieces).

Nous décrirons en détail les moyens de compensation des variations dimensionnelles.We will describe in detail the means of compensation of dimensional variations.

Il s'agit d'un dispositif à excentrique formé par l'assemblage d'une bague intérieure 12 et d'une bague extérieure 13, en matériau plastique ou métallique, obtenues par une série d'usinages réalisés par décolletage.This is an eccentric device formed by the assembly of an inner ring 12 and an outer ring 13, plastic or metal material, obtained by a series of machining performed by bar turning.

Les bagues excentriques possèdent un diamètre extérieur circulaire et un trou décentré, le diamètre extérieur de la plus petite bague 12 (la bague intérieure) excentrique de la paire correspondant au diamètre du trou décentré pratiqué dans la plus grande bague excentrique 13 (la bague extérieur). Les trous décentrés des petites bagues excentriques peuvent être amenés en alignement précis l'un par rapport à l'autre par une simple rotation des bagues excentriques de la paire.The eccentric rings have a circular outer diameter and an off-center hole, the outer diameter of the smaller eccentric ring 12 (the inner ring) of the pair corresponding to the diameter of the off-center hole in the larger eccentric ring 13 (the outer ring). . The off-center holes of the small eccentric rings can be brought into precise alignment with each other by a simple rotation of the eccentric rings of the pair.

Les deux bagues sont emmanchées en force dans un trou débouchant réalisé dans l'un des substrats en regard sensiblement du trou non débouchant réalisé dans le substrat recevant l'insert 5.The two rings are force-fitted in a through-hole made in one of the substrates facing substantially the non-emerging hole made in the substrate receiving the insert 5.

La disposition d'ensemble dans le trou du substrat forme alors un coussinet d'appui pour l'insertion de l'élément de fixation 15 en forme de tige, par exemple un boulon à visser qui devra connecter à la structure porteuse.The overall arrangement in the hole of the substrate then forms a bearing pad for the insertion of the fixing element 15 in the form of a rod, for example a bolt to be screwed which will have to connect to the supporting structure.

L'élément de fixation 15 en forme de tige peut y être logé directement ou même indirectement en utilisant une douille 14 de montage s'étendant entre les surfaces extérieures du substrat 2.The rod-shaped fastening element 15 can be housed directly or indirectly by using a socket 14 of mounting extending between the outer surfaces of the substrate 2.

Dans l'exemple représenté en figure 1, la douille 14 qui est liée à l'une des bagues (la bague intérieure 12) est pourvue de moyen de connexion (un filetage par exemple) permettant son assemblage et sa solidarisation au deuxième élément 7 formant à le premier élément 4 les moyens de glissement.In the example shown in figure 1 , the sleeve 14 which is connected to one of the rings (the inner ring 12) is provided with connecting means (a thread for example) for its assembly and attachment to the second element 7 forming the first element 4 the means of sliding.

La longueur de la douille 14 de montage de préférence cylindrique est adaptée à l'épaisseur du substrat 2, de telle façon qu'elle ne dépasse pas au-delà des faces de la vitre après sa mise en place dans d'un coussinet d'appui et d'étanchéité 16. Selon les possibilités, les faces d'extrémité de la douille de montage doivent se trouver à fleur des faces des substrats.The length of the preferably cylindrical mounting sleeve 14 is adapted to the thickness of the substrate 2, so that it does not protrude beyond the faces of the glass after being placed in a bearing bush. 16. Depending on the possibilities, the end faces of the mounting sleeve must lie flush with the faces of the substrates.

Selon une caractéristique avantageuse de l'invention, il est nécessaire d'introduire entre l'espace situé entre les substrats et l'environnement un orifice permettant une fuite du fluide dont l'une de ses variables d'état thermodynamique a varié. Il est prévu des ouvertures d'introduction et/ou d'échappement d'air dans la douille de montage et/ou dans les bagues excentriques.According to an advantageous characteristic of the invention, it is necessary to introduce between the space between the substrates and the environment an orifice allowing leakage of the fluid, one of its thermodynamic state variables has varied. Air introduction and / or exhaust openings are provided in the mounting sleeve and / or in the eccentric rings.

L'un des avantages de l'invention réside dans le fait que dans l'éventualité d'un bris d'un des substrats constitutifs de la façade, notamment au plus proche de la structure porteuse, il n'engendre pas d'instabilité dangereuse des autres composants vis-à-vis de la dite structure.One of the advantages of the invention lies in the fact that in the event of a breakage of one of the substrates constituting the facade, especially closer to the supporting structure, it does not generate dangerous instability other components vis-a-vis the said structure.
