Abstract

The system consists of cutting small pieces from the face of a tile and making holes through the tile and in the wall. Plugs of a non-degradable material are inserted between the tile and wall round an inclined tube used as a guide for a fixing dowel, e.g. of carbon or glass fibre, and filled with a sealing compound. After fixing, the small pieces of tile are replaced in its face to conceal the dowel ends.

Description

La présente invention concerne un dispositif pour fixer un revêtement de surface composé de carreaux sur une façade. The present invention relates to a device for fixing a surface covering composed of tiles on a facade.

La fixation de ces revêtements est traditionnellement effectuée à l'aide d'agrafes métalliques reliant les éléments du revêtement à la façade support, le plus généralement avec un vide d'air centimétrique. Ces agrafes et les carreaux sont altérables dans le temps plus ou moins rapidement selon les conditions météorologiques, environnementales et géographiques. Cette altération peut se produire par fatigue sous vibrations ou par incompatibilité des matériaux, métal - carreaux. Il est souvent décidé lors d'un tel sinistre de détruire le revêtement initial, pour le remplacer ensuite intégralement (agrafes et carreaux). The fixing of these coatings is traditionally carried out using metal staples connecting the elements of the coating to the support facade, most generally with a centimeter vacuum. These staples and tiles are alterable over time more or less quickly depending on weather, environmental and geographic conditions. This deterioration can occur by fatigue under vibration or by incompatibility of materials, metal - tiles. It is often decided during such a disaster to destroy the initial coating, and then replace it entirely (staples and tiles).

Le dispositif selon l'invention permet de re-fixer le revêtement initial sans changer ni démonter les carreaux, ce qui permet de conserver l'existant (avantage esthétique), de minimiser les travaux (avantage économique), et d'apporter une nouvelle sécurité avec une fixation souple et inaltérable (avantage technique).

The device according to the invention makes it possible to re-fix the initial coating without changing or dismantling the tiles, which makes it possible to preserve the existing (aesthetic advantage), to minimize the work (economic advantage), and to provide new security. with a flexible and unalterable fixing (technical advantage).

Le dispositif est composé d'une cheville en matière inaltérable (fibre de verre ou f carbone), mise en place et scellée grâce à un coffrage perdu du vide d'air entre la façade support et le carreau. Une extrémité de la cheville est scellée dans le support et l'autre dans la masse du carreau. Ces scellements sont effectués à l'aide de matériaux en résine compatible avec la cheville et le carreau. The device is composed of an anchor made of unalterable material (fiberglass or carbon), placed and sealed thanks to a formwork lost from the air gap between the support facade and the tile. One end of the dowel is sealed in the support and the other in the mass of the tile. These seals are made using resin materials compatible with the dowel and the tile.

La mise en place de la cheville et son scellement sont effectués de la façon suivante, la planche 1 annexée illustre le procédé repères 1 à 6 comme suit : - Découpe d'une pastille du carreau au niveau de l'attache à poser (1) ; - Perçage incliné du carreau puis de la façade support (2) ; - Mise en place du coffrage perdu (3) ; - Remplissage avec le matériaux de scellement (4) ; - Mise en place de la cheville (5) ; - Reconstitution superficielle du carreau à l'endroit du perçage (6). The installation of the dowel and its sealing are carried out in the following manner, the appended plate 1 illustrates the process marks 1 to 6 as follows: - Cutting of a patch of the tile at the level of the fastener to be laid (1) ; - Angled drilling of the tile then of the support facade (2); - Installation of the lost formwork (3); - Filling with sealing materials (4); - Installation of the ankle (5); - Superficial reconstruction of the tile at the location of the hole (6).

La taille des perçages varie en fonction des diamètres des chevilles qui varient en fonction de la géométrie des carreaux et des efforts qu'ils subissent.The size of the holes varies according to the diameters of the dowels which vary according to the geometry of the tiles and the forces they undergo.

Claims

CLAIMS 1) Device for fixing the coverings composed of tiles on a facade, characterized in that it comprises a dowel of unalterable material placed and sealed at one of these ends in the mass of the tile and at the other end in the support facade.

2) A method of using the device according to claim 1, in the case where there is a vacuum between the facade and the tiles, characterized in that the crossing of the vacuum is carried out using 'a lost formwork.

3) Method for fixing the coverings composed of tiles on a facade, using a device according to claim 1, characterized by the following steps: cutting a patch of the tile at the fastener to be laid (1 ); inclined drilling of the tile then of the support facade (2); placing the lost formwork (3); filling with the sealing material (4); fitting the ankle (5); surface reconstruction of the tile at the location of the hole (6).
