Description

La présente invention concerne le domaine du bâtiment, en particulier du revêtement de façades ou de cloisons par des éléments formant une peau, froide ou isolante, et a pour objet un panneau à revêtement en pierre mince.The present invention relates to the building sector, in particular the coating of facades or partitions with elements forming a skin, cold or insulating, and relates to a panel coated with thin stone.

L'invention a également pour objet un procédé d'alignement de la face avant de tels panneaux par rap­port à l'infrastructure.The invention also relates to a method of aligning the front face of such panels with respect to the infrastructure.

Actuellement, les revêtements de façades et de cloisons en pierre sont généralement réalisés en peau froide, c'est-à-dire par montage avec réalisation d'un espace d'air entre la façade à revetir et le revêtement en pierre. Un tel montage met en oeuvre des éléments lourds exigeant une structure porteuse et des moyens de manutention très lourds, de sorte que le format des pier­res utilisées est restreint.Currently, the cladding of facades and stone partitions are generally made of cold skin, that is to say by mounting with creation of an air space between the facade to be coated and the stone cladding. Such an assembly uses heavy elements requiring a load-bearing structure and very heavy handling means, so that the size of the stones used is limited.

En effet, pour des raisons de résistance des matériaux, les pierres utilisées doivent présenter une épaisseur minimum qui est de l'ordre de 3 cm, ce qui en­traîne un poids élevé pour un format relativement faible.Indeed, for reasons of resistance of the materials, the stones used must have a minimum thickness which is of the order of 3 cm, which results in a high weight for a relatively small format.

En outre, sur ce type de façade la sécurité reste aléatoire, aucun élément de retenu n'étant prévu dans le cas d'un bris de pierre, de sorte que les diffé­rents morceaux tombent et présentent un risque de blessu­re pour les passants.In addition, security on this type of facade remains uncertain, no element of restraint being provided in the event of a break in stone, so that the various pieces fall and present a risk of injury to passers-by.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un panneau à revê­tement en pierre, caractérisé en ce qu'il est essentiel­lement constitué par une plaque en pierre mince et par un élément de rigidification de la plaque coopérant avec un support de fixation sur l'infrastructure.It has, in fact, for its object a panel coated with stone, characterized in that it is essentially constituted by a thin stone plate and by a stiffening element of the plate cooperating with a mounting bracket on the infrastructure.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à des modes de réa­lisation préférés, donnés à titre d'exemples non limita­tifs, et expliqués avec référence aux dessins schémati­ques annexés, dans lesquels :

  • la figure 1 est une vue partielle en coupe d'un panneau conforme à l'invention ;
  • la figure 2 est une vue analogue à celle de la figure 1, représentant une première variante de réalisa­tion du panneau, et
  • les figures 3 et 4 sont des vues analogues à celles des figures 1 et 2 d'autres variantes de réalisa­tion de l'invention.
The invention will be better understood from the following description, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a partial sectional view of a panel according to the invention;
  • FIG. 2 is a view similar to that of FIG. 1, showing a first alternative embodiment of the panel, and
  • Figures 3 and 4 are views similar to those of Figures 1 and 2 of other alternative embodiments of the invention.

Le panneau à revêtement en pierre, représenté, à titre d'exemple, sur la figure 1 des dessins annexés, est essentiellement constitué par une plaque en pierre mince 1 et par un élément 2 de rigidification de la pla­que 1 coopérant avec un support 3 de fixation sur l'in­frastructure.The stone-clad panel, shown, for example, in Figure 1 of the accompanying drawings, is essentially constituted by a thin stone plate 1 and by an element 2 for stiffening the plate 1 cooperating with a support 3 of fixing on the infrastructure.

L'élément 2 de rigidification de la plaque en pierre mince 1 est avantageusement constitué par une ar­mature en fibre de verre, en fibre de matière synthéti­que, en polyester ou autre, et est fixé sur la face ar­rière de la plaque 1 au moyen d'une colle polyuréthanne, de résines époxy, ou autres.The element 2 for stiffening the thin stone plate 1 is advantageously constituted by a fiberglass, synthetic fiber, polyester or other frame, and is fixed to the rear face of the plate 1 by means of polyurethane glue, epoxy resins, or others.

La plaque en pierre mince 1 est sous forme d'une plaque de pierre naturelle ou artificielle, d'un élément silico-calcaire, ou d'un autre élément en plaque, tel que céramique, terre cuite, béton de résine, etc... destiné à l'habillage de façade et présente une faible épaisseur et une surface importante par rapport à ladite épaisseur. En effet, l'épaisseur d'une telle plaque peut être de l'ordre de 12 à 14 mm et sa surface de l'ordre de 1,5 m² à 3 m². Ainsi, par rapport à un mode de revê­tement traditionnel par pierre, la solution conforme à l'invention permet un gain important en poids, de l'ordre de 60 % en format, la surface d'un panneau pouvant être jusqu'à quatre fois plus importante que dans les modes de revêtement connus, et en sécurité, les morceaux étant re­tenus par l'élément de rigidification 2 en cas de bris de la plaque 1. En outre, l'effet esthétique est sensible­ment amélioré par rapport au petit dammier obtenu avec les plaques de revêtement traditionnelles. Enfin, du fait de la réduction d'épaisseur, dont la réduction correspon­dante de résistance à la rupture est palliée par l'élé­ment 2, il est possible de réaliser un gain de prix de revient de l'ordre de 30 %, essentiellement par économie de matière première (pierre).The thin stone plate 1 is in the form of a natural or artificial stone plate, a lime-sand element, or another element in plate, such as ceramic, terracotta, resin concrete, etc. intended for the cladding of the facade and has a small thickness and a large surface area with respect to said thickness. Indeed, the thickness of such a plate can be of the order of 12 to 14 mm and its surface of the order of 1.5 m² to 3 m². Thus, compared to a traditional stone coating method, the solution conforms to the invention allows a significant gain in weight, of the order of 60% in format, the surface of a panel being able to be up to four times larger than in known coating methods, and in safety, the pieces being retained by the stiffening element 2 in the event of breakage of the plate 1. In addition, the aesthetic effect is appreciably improved compared to the small dammier obtained with the traditional covering plates. Finally, due to the reduction in thickness, the corresponding reduction in breaking strength of which is offset by element 2, it is possible to achieve a cost saving of around 30%, essentially by saving of raw material (stone).

Le support 3 de fixation sur l'infrastructure peut être constitué, comme le montre la figure 1, par un caisson 4 en tôle ou autre, muni dans son fond d'une cou­che de matière isolante 5 et présentant un rebord 6 de fixation de l'élément 2 et de la plaque 1, au moyen d'un mastic ou d'une résine 7, ce rebord délimitant, entre la couche de matière isolante 5 et l'élément 2, une lame d'air ventilée grâce à des orifices 8 prévus dans ledit rebord 6. Ainsi, il est possible de réaliser un panneau-­sandwich ventilé pour mur-rideau monté directement sur l'infrastructure du bâtiment à équiper.The support 3 for fixing to the infrastructure may be constituted, as shown in FIG. 1, by a box 4 made of sheet metal or the like, provided at its bottom with a layer of insulating material 5 and having a flange 6 for fixing the element 2 and plate 1, by means of a sealant or a resin 7, this rim delimiting, between the layer of insulating material 5 and element 2, a layer of air ventilated by orifices 8 provided in said flange 6. Thus, it is possible to produce a ventilated sandwich panel for curtain wall mounted directly on the infrastructure of the building to be equipped.

Il est également possible, comme le montre la figure 2, de réaliser un panneau-sandwich non ventilé, dont le support 3 de fixation sur l'infrastructure est constitué par un caisson 4 muni dans son fond d'une cou­che de matière isolante 5 et présentant un rebord 6 de fixation de l'élément 2 et de la plaque 1, au moyen d'un mastic ou d'une résine 7, la couche de matière isolante 5 étant appliquée directement contre l'élément 2.It is also possible, as shown in FIG. 2, to produce a non-ventilated sandwich panel, the support 3 for fixing to the infrastructure consists of a box 4 provided at its bottom with a layer of insulating material 5 and having a rim 6 for fixing the element 2 and the plate 1, by means of a putty or a resin 7, the layer of insulating material 5 being applied directly against the element 2.

La figure 3 représente une variante de réalisa­tion de l'invention, dans laquelle le support 3 de fixa­tion sur l'infrastructure est constitué par un cadre pé­ripérique de montage 9 coopérant, par l'intermédiaire d'un mastic ou d'une résine de collage 7, avec un contre-­parement 10 constitué par une plaque silico-calcaire, en fibro-ciment, métallique, synthétique ou autre, collée sur l'élément de rigidification 2.FIG. 3 represents an alternative embodiment of the invention, in which the support 3 for fixing to the infrastructure is constituted by a peripheral mounting frame 9 cooperating, via a sealant or a bonding resin 7, with a counter-facing 10 constituted by a silica-limestone plate, made of fiber cement, metallic, synthetic or other, bonded to the stiffening element 2.

Afin de parfaire la liaison entre l'ensemble plaque 1, élément 2 et contre-parement 10, ce dernier peut avantageusement être pourvu de pattes de liaison 12 avec le cadre périphérique 9 fixé audit contre-parement 10 par l'intermédiaire d'ensembles vis et écrou 11 tra­versant ledit contre-parement 10 et dont les vis sont montées dans ce dernier, ou encore dont les écrous sont noyés dans ce dernier, avant assemblage avec la plaque 1 et l'élément 2. Dans ce dernier cas, il est possible d'obtenir des ensembles plaque 1, élément 2 et contre-­parement 10 ne présentant aucun élément en saillie.In order to perfect the connection between the plate 1, element 2 and counter-facing 10 assembly, the latter can advantageously be provided with connecting lugs 12 with the peripheral frame 9 fixed to said counter-facing 10 by means of screw assemblies. and nut 11 passing through said counter-facing 10 and the screws of which are mounted therein, or the nuts of which are embedded in the latter, before assembly with the plate 1 and the element 2. In the latter case, it is possible to obtain plate 1, element 2 and counter-facing 10 assemblies having no projecting element.

Les ensembles vis et écrou 11 permettent la fixation des pattes de liaison 12 lors du montage de l'ensemble plaque 1, élément 2 et contre-parement 10 sur le cadre périphérique 9 et permettent, en cas de rupture de l'ensemble précité, de retenir les éléments de ce der­nier sur le cadre 9.The screw and nut assemblies 11 allow the connection lugs 12 to be fixed during assembly of the plate 1, element 2 and counter-facing 10 assembly on the peripheral frame 9 and allow, in the event of the aforementioned assembly to be broken, retain the elements of the latter on frame 9.

Le mode de réalisation représenté à la figure 3 permet la réalisation d'un élément sandwich destiné à l'habillage en peau froide, dont les panneaux sont pour­vus de pattes de sécurité mécanique.The embodiment shown in FIG. 3 allows the production of a sandwich element intended for covering in cold skin, the panels of which are provided with mechanical safety tabs.

La figure 4 représente une autre variante de réalisation de l'invention, dans laquelle le support 3 de fixation sur l'infrastructure est simplement réalisé par des pattes de fixation 13 solidarisées avec la plaque en pierre mince 1 et l'élément 2 de rigidification par l'in­termédiaire d'ensembles vis et écrou 11, dont les vis sont montées dans un contre-parement 10 collé sur l'élé­ment 2 de rigidification. Ce mode de réalisation est ap­plicable à tout type de revêtement de façade ou autre.FIG. 4 represents another alternative embodiment of the invention, in which the support 3 for fixing to the infrastructure is simply produced by fixing lugs 13 secured to the thin stone plate 1 and the element 2 for stiffening by through screw and nut assemblies 11, the screws of which are mounted in a counter-facing 10 glued to the stiffening element 2. This embodiment is applicable to any type of facade or other coating.

Dans ce dernier mode de réalisation, les plans de collage entre la plaque en pierre mince 1, l'élément de rigidification 2 et le contre-parement 10 peuvent avantageusement être protégés par un cadre périphérique 14 en silicone, en néoprène, en aluminium, en chlorure de polyvinyle ou autre. Ce cadre de protection est destiné à éviter toute pénétration accidentelle d'humidité ou autre dans les plans de collage.In this latter embodiment, the bonding planes between the thin stone plate 1, the element stiffening 2 and the counter-facing 10 can advantageously be protected by a peripheral frame 14 made of silicone, neoprene, aluminum, polyvinyl chloride or the like. This protective frame is intended to prevent any accidental penetration of moisture or other into the bonding planes.

Les plaques en pierre mince 1 peuvent présenter de manière connue des tolérances d'épaisseur assez impor­tantes, pouvant varier de 2 mm à 4 mm sur une épaisseur normale de 12 mm, cette variation étant due au processus de découpe des plaques et provoquant un "phénomène de queue de billard" défavorable à une prise en feuillure d'un panneau. En effet, une telle prise en feuillure doit être constante et doit s'effectuer avec une tolérance de + ou - 1 mm.The thin stone slabs 1 can have fairly large thickness tolerances in known manner, which can vary from 2 mm to 4 mm over a normal thickness of 12 mm, this variation being due to the process of cutting the plates and causing a "phenomenon billiard cue "unfavorable for a rebate of a panel. Indeed, such rebating must be constant and must be carried out with a tolerance of + or - 1 mm.

Actuellement, cette tolérance ne peut être res­pectée que par un profilage de la plaque 1, ce qui en­traîne forcément une opération supplémentaire de traite­ment de ladite plaque 1 et un surcoût important.Currently, this tolerance can only be met by profiling the plate 1, which necessarily leads to an additional processing operation of said plate 1 and a significant additional cost.

La présente invention a également pour but de pallier cet inconvénient en proposant un procédé d'ali­gnement de la face avant de la plaque 1 par rapport à l'infrastructure, caractérisé en ce qu'il consiste essen­tiellement à calibrer l'épaisseur de prise en feuillure sur le joint dans le cas de réalisation de panneaux-­sandwichs ventilés ou non ou de panneaux de peau froide montés sur cadre ou à régler mécaniquement ledit aligne­ment par variation de la position des pattes de fixation 13 sur l'infrastructure, également dans le cas de pan­neaux de peau froide.The present invention also aims to overcome this drawback by proposing a method of aligning the front face of the plate 1 relative to the infrastructure, characterized in that it consists essentially in calibrating the thickness of rebate grip on the joint in the case of sandwich panels ventilated or not or cold skin panels mounted on a frame or to mechanically adjust said alignment by varying the position of the fixing lugs 13 on the infrastructure, also in the case of cold skin panels.

Dans le premier cas, et comme le montrent les figures 1 à 3, la plaque 1 est positionnée sur le rebord 6 du caisson 4 ou sur le cadre périphérique 9, avec in­terposition d'un joint souple interne 15 encollé sur ses deux faces, et est maintenue au moyen de calibres 16, dont les ouvertures correspondent à l'épaisseur de prise en feuillure et qui sont disposés sur les côtés du pan­neau, le joint de collage 7 étant alors appliqué dans l'espace délimité par le joint 15, le bord de l'ensemble plaque 1 - élément 2 et le rebord 6 du caisson 4 ou le bord du cadre périphérique 9, les gabarits 16 étant reti­rés après séchage du produit de collage. Ainsi, l'épais­seur de prise en feuillure de panneaux obtenus présente une dimension constante, les variations d'épaisseur de la plaque 1 étant compensées par un écrasement plus ou moins prononcé du joint souple interne 15, le joint de collage 7 figeant cette position.In the first case, and as shown in FIGS. 1 to 3, the plate 1 is positioned on the rim 6 of the box 4 or on the peripheral frame 9, with the interposition of an internal flexible seal 15 glued on its two faces, and is maintained by means of 16 gauges, the openings of which correspond to the setting thickness in rebate and which are arranged on the sides of the panel, the bonding joint 7 then being applied in the space delimited by the joint 15, the edge of the plate 1 - element 2 assembly and the rim 6 of the box 4 or the edge of the peripheral frame 9, the templates 16 being removed after drying of the bonding product. Thus, the thickness of the rebate of panels obtained has a constant dimension, the variations in thickness of the plate 1 being compensated for by a more or less pronounced crushing of the internal flexible seal 15, the adhesive seal 7 freezing this position.

Selon une variante de réalisation de l'inven­tion, dans le cas d'un panneau-sandwich formant peau froide, tel que représenté à la figure 4, le réglage mé­canique de l'alignement de la plaque 1 par variation de la position des pattes de fixation 13 sur l'infrastructu­re s'effectue par déplacement desdites pattes 13 relati­vement à ladite infrastructure et par guidage de ces pat­tes sur leur moyen de fixation 18 à ladite infrastructu­re. Ainsi, les pattes de fixation 13 peuvent avantageuse­ment être munies d'un trou oblong 19, dont la largeur correspond au diamètre d'un boulon ou d'une vis 18 de fi­xation sur l'infrastructure et dont la longueur corres­pond à la latitude de réglage.According to an alternative embodiment of the invention, in the case of a sandwich panel forming a cold skin, as shown in FIG. 4, the mechanical adjustment of the alignment of the plate 1 by variation of the position of the legs fixing 13 to the infrastructure is effected by displacement of said legs 13 relative to said infrastructure and by guiding these legs on their means of attachment 18 to said infrastructure. Thus, the fixing lugs 13 can advantageously be provided with an oblong hole 19, the width of which corresponds to the diameter of a bolt or of a screw 18 for fixing to the infrastructure and the length of which corresponds to the latitude of adjustment. .

Grâce au procédé d'alignement de la face avant de la plaque 1, le prix de revient des panneaux conformes à l'invention peut être substantiellement réduit du fait de l'économie possible sur le coût des pierres utilisées qui ne nécessitent pas d'être calibrées.Thanks to the alignment process of the front face of the plate 1, the cost price of the panels according to the invention can be substantially reduced due to the possible savings on the cost of the stones used which do not need to be calibrated.

Grâce à l'invention il est possible de réaliser des revêtements de façades, en particulier des murs-­rideaux avec des panneaux en éléments de pierre, présen­tant une grande surface unitaire et un poids relativement faible et pouvant facilement être montés, du fait de leur présentation mono-bloc.Thanks to the invention it is possible to produce facade coverings, in particular curtain walls with panels made of stone elements, having a large unit area and a relatively low weight and which can easily be mounted, due to their presentation. mono-block.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
