Definitions

• the present invention relates to a manu ⁇ billed decorative laminate element, in particular for coating the interior walls of buildings, and its manufacturing process.
• 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.
• the object of the present invention is also to provide a ready-to-use decorative laminated decorative element for the interior design of buildings.
• 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.
• 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.
• 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.
• 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.
• 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.
• Figure 1 shows, in section, the laminated element according to the invention.
• 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.
• 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.
• 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.
• 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.
• 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.
• a laminated element according to the invention reproducing a structured decoration in pine can be very easily produced from the compositions next of the 3 layers.
• the non-essential acrylic resin is used to improve the plasticity of the decorative mortar.
• - filamentary layer a glass mesh of square mesh 5 x 5 mm is applied to the surface of the mortar which has just been placed.
• the atomized cruor corresponds to animal proteins extracted from whole blood. It is used to facilitate the coating of the polystyrene beads.
• the sodium aluminate is used as setting accelerator. It increases the rotational speed of the molds used.
• the decorative laminate element according to the invention finds its application in all cases where a decorative finish of building walls is required.
• the installation of this element can for example be carried out by means of bonding by studs directly on a load-bearing wall in masonry or shuttered concrete.
• the constitution of the element according to the invention makes it possible to easily make on-site cuts by sawing by hand or using an appropriate power tool.
