Description

Elément stratifié décoratif pour le bâtimentDecorative laminate for the building
La présente invention concerne un élément stratifié décoratif manu¬ facturé, notamment pour le revêtement des murs intérieurs de bâti¬ ments, et son procédé de fabrication.The present invention relates to a manu¬ billed decorative laminate element, in particular for coating the interior walls of buildings, and its manufacturing process.
Actuellement, de nombreux matériaux décoratifs peuvent être utilisés pour le revêtement de murs intérieurs ou plafonds de bâtiments. Il peut s'agir notamment de matériaux naturels comme le bois, de maté¬ riaux synthétiques (revêtements plastiques), ou encore de pierres naturelles ou de briques décoratives en terre cuite maçonnées avec un mortier tradionnel.Currently, many decorative materials can be used for coating interior walls or building ceilings. It can be in particular natural materials such as wood, synthetic materials (plastic coatings), or even natural stones or decorative bricks in terracotta masonry with a traditional mortar.
Dans le cas de maçonneries armées en béton, il est également connu de coller sur les banches métalliques servant de coffrage des matri¬ ces structurées en caoutchouc synthétique. Ces matrices présentent un relief qui est reproduit sur la surface du béton coulé dans la banche.Toutefois, ces différentes solutions demandent d'une part une main-d'oeuvre spécialisée pour l'obtention de ce parement décora¬ tif et d'autre part l'intervention de différents corps d'état (maçons, menuisiers, staffeurs) selon le matériau utilisé.In the case of reinforced concrete masonry, it is also known to adhere to metal formwork serving as formwork for matri¬ these structured in synthetic rubber. These matrices have a relief which is reproduced on the surface of the concrete poured into the formwork. However, these different solutions require, on the one hand, specialized labor for obtaining this decorative facing and, on the other hand the intervention of different trades (masons, carpenters, staffers) depending on the material used.
Aussi la présente invention a pour but de fournir un élément strati¬ fié décoratif manufacturé prêt-à-l'emploi pour l'aménagement intérieur de bâtiments .The object of the present invention is also to provide a ready-to-use decorative laminated decorative element for the interior design of buildings.
Ce but est atteint du fait que, conformément à l'invention, l'élément stratifié est constitué d'une couche de mortier, correspondant au parement décoratif, une couche filamenteuse et une couche de béton léger. La couche de quelques millimètres d'épaisseur d'un mortier constitué d'un mélange de sable et de liant hydraulique peut être co- lorée par des oxydes métalliques de synthèse choisis en fonction de l'aspect esthétique recherché. Le liant hydraulique peut par exemple être choisi parmi les ciments Portland artificiels éventuellement avec constituants secondaires. Il peut aussi être utilisé du ciment blanc suivant la teinte recherchée du parement décoratif. Le relief de la surface du mortier est obtenu par l'utilisation d'une matrice de coffrage en caoutchouc synthétique. Cette matrice peut être choi¬ sie parmi les matrices disponibles du commerce utilisées pour les coffrages en béton ou bien encore être réalisée à façon à partir de résines souples du commerce (telles les résines polyuréthanes à deux composants) pour tout relief spécifique souhaité.This object is achieved because, according to the invention, the laminated element consists of a layer of mortar, corresponding to the decorative facing, a filamentary layer and a layer of light concrete. The layer a few millimeters thick of a mortar made of a mixture of sand and hydraulic binder can be colored with synthetic metal oxides chosen according to the desired aesthetic appearance. The hydraulic binder can for example be chosen from artificial Portland cements, optionally with secondary constituents. White cement can also be used depending on the desired shade of the decorative facing. The relief of the mortar surface is obtained by the use of a matrix formwork in synthetic rubber. This matrix can be chosen from the commercially available matrices used for concrete formwork or even be made to order from commercial flexible resins (such as two-component polyurethane resins) for any specific relief desired.
La couche filamenteuse est par exemple constituée d'un treillis en fibres de verre. Les mailles du treillis sont de dimensions de l'or¬ dre de 5 à 10 millimètres.The filamentary layer consists, for example, of a glass fiber mesh. The meshes of the trellis have dimensions of the order from 5 to 10 millimeters.
La couche de béton léger de quelques centimètres d'épaisseur est constituée d'un mélange de liant hydraulique, de billes de polysty¬ rène expansé et d'eau. La masse volu ique de ce béton léger est comprise entre 200 et 400 kg/m3, ce qui permet d'obtenir un élément particulièrement léger. La faible masse volumique de l'élément selon l'invention confère à celui-ci une performance d'isolation thermique intéressante qui peut être mise à profit pour le revête¬ ment intérieur de parois de bâtiments. Ainsi pour une masse volumi¬ que de 300 kg/m3, le coefficient de conductivité thermique est égal à 0,08 W/m.°C. Une amélioration de l'enrobage des billes de polysty¬ rène par la pâte de ciment peut être obtenue par l'utilisation d'adjuvants spécifiques, tel notamment celui décrit dans la demande de brevet d'invention n° 76 37653. Les billes de polystyrène ex¬ pansé peuvent être remplacées par tout autre matériau léger disponi- ble localement, tels par exemple la perlite ou la vermiculite.The layer of light concrete a few centimeters thick consists of a mixture of hydraulic binder, expanded polystyrene beads and water. The density of this light concrete is between 200 and 400 kg / m3, which makes it possible to obtain a particularly light element. The low density of the element according to the invention gives it an advantageous thermal insulation performance which can be used for the interior coating of building walls. Thus for a density of 300 kg / m3, the coefficient of thermal conductivity is equal to 0.08 W / m. ° C. An improvement in the coating of the polystyrene balls with the cement paste can be obtained by the use of specific additives, such as in particular that described in the patent application No. 76 37653. The polystyrene balls ex¬ dressed may be replaced by any other light material available locally, such as perlite or vermiculite.
Selon une variante, une barbotine de ciment peut être interposée entre la couche de mortier et la couche filamenteuse, dans le cas particulier où le relief correspond par exemple à une imitation de pierres naturelles ou de briques en terre cuite maçonnées. Cette barbotine permet d'obtenir directement une teinte des joints contras¬ tant avec la teinte des pierres ou des briques, sans intervention ultérieure à la fabrication de l'élément.According to a variant, a cement slip can be interposed between the layer of mortar and the filamentary layer, in the particular case where the relief corresponds for example to an imitation of natural stones or masonry bricks. This slip makes it possible to directly obtain a color of the contras¬ joints as much with the color of the stones or bricks, without subsequent intervention in the manufacture of the element.
La figure 1 représente, en coupe, l'élément stratifié selon l'inven¬ tion.Figure 1 shows, in section, the laminated element according to the invention.
La figure 2 représente, en coupe, une variante de cet élément. La figure 3 représente, en coupe, le moule utilisé pour la réalisa¬ tion de l'élément ainsi que les différentes couches de celui-ci.Figure 2 shows, in section, a variant of this element. Figure 3 shows, in section, the mold used for the realization of the element as well as the different layers thereof.
L'élément représenté sur la figure 1 comporte un parement décoratif 1 en mortier de quelques millimètres d'épaisseur, possédant une surface en relief 4, une couche filamenteuse 2 constituée par exemple d'un treillis de verre, une couche de béton léger 3.The element represented in FIG. 1 comprises a decorative facing 1 in mortar a few millimeters thick, having a raised surface 4, a filamentary layer 2 constituted for example by a glass lattice, a layer of light concrete 3.
La variante selon la figure 2 correspond à un motif décoratif repro- duisant par exemple des petites briques maçonnées. Une barbotine de ciment 5 permet de différencier la teinte du mortier 1 constituant les briques de celle du joint 6.The variant according to FIG. 2 corresponds to a decorative motif reproducing, for example, small masonry bricks. A cement slip 5 makes it possible to differentiate the color of the mortar 1 constituting the bricks from that of the joint 6.
Le procédé de fabrication schématisé sur la figure 3 consiste à utili- ser un moule rectangulaire comprenant des joues verticales 7 et un fond' de moule 8 adapté au type de relief choisi pour le parement. Le mortier 1 est étalé en fond de moule. La mise en place peut être facilitée par l'utilisation d'une vibration. Puis la couche filamen¬ teuse 2 est appliquée sur la surface libre du mortier. Enfin la couche de béton léger 3 est mise en place par exemple par compression ou par tout autre procédé connu, puis arrasée au niveau supérieur du moule. L'élément ainsi fabriqué est démoulé après durcissement du mortier et du béton.The manufacturing process shown diagrammatically in FIG. 3 consists in using a rectangular mold comprising vertical cheeks 7 and a mold base 8 adapted to the type of relief chosen for the facing. The mortar 1 is spread at the bottom of the mold. The installation can be facilitated by the use of a vibration. Then the filamentous layer 2 is applied to the free surface of the mortar. Finally, the layer of light concrete 3 is placed, for example by compression or by any other known method, then leveled at the upper level of the mold. The element thus produced is demolded after hardening of the mortar and concrete.
L'élément stratifié suivant l'invention est très léger. Les dimensions maximales de cet élément sont de 2 à 3 mètres environ pour la longueur pour une largeur maximale de l'ordre de 1 mètre. La composition des différentes couches de cet élément correspond à un matériau ininflam¬ mable, ce qui ne restreint pas les domaines d'emploi de cet élément.The laminated element according to the invention is very light. The maximum dimensions of this element are 2 to 3 meters approximately for the length for a maximum width of the order of 1 meter. The composition of the different layers of this element corresponds to a non-flammable material, which does not restrict the fields of use of this element.
