Said invention refers to a process for the manufacture of boards, in different thickness and size measurements, taking advantage of any piece of natural stone (marble, granite, slate, limestone, quartzite or similar) or arti fi cial. The stone pieces are placed on a base made with a special mixture of cement mortar composed of white cement, crushed marble, silica, quartz, granite or similar, an accelerator, a hydrofugante, a fl uidi fi cant and a thermal and acoustic insulator, allowing the manufacture of boards of different sizes and thickness, suitable for placement as a coating both outside and inside buildings.
La mejora de la patente en cuestión consiste en la utilización de un puente de unión de naturaleza química, aplicable entre el mortero base y el material a colocar. El puente de unión a utilizar, puede ser de resinas acrílicas, resinas epoxi, resinas de poliéster, resinas de poliuretano o similar, y tendrá la particularidad de endurecer con el mortero fresco, anclando el material a colocar. Este material puede ser de diversa índole (cristal, espejo, plástico, madera, porcelana, gres, piedra artificial de naturaleza cementosa o de resinas sintéticas, o similar), siempre que se caracterice por su baja porosidad. Estado de la técnica The improvement of the patent in question consists in the use of a chemical bonding bridge, applicable between the base mortar and the material to be placed. The bridge to be used can be acrylic resins, epoxy resins, polyester resins, polyurethane resins or similar, and will have the particularity of hardening with the fresh mortar, anchoring the material to be placed. This material can be of various kinds (glass, mirror, plastic, wood, porcelain, stoneware, artificial stone of cementitious nature or synthetic resins, or similar), provided it is characterized by its low porosity. State of the art
Actualmente, la colocación en paredes de piedras naturales (mármoles, pizarras, granitos, etc.), ya sea en interiores como en exteriores, se realiza sobre la pared de una forma manual colocando una a una cada piedra, que seguidamente debe ser nivelada para mantener un equilibrio en la superficie de la pared, evitando que las piedras sobresalgan en exceso unas de otras. Una vez revestida toda la superficie de la pared es necesario realizar un rejuntado con cemento de todas las zonas comprendidas entre cada dos piedras, además si se desea un aspecto más llamativo se puede proceder a un barnizado para resaltar el color de la piedra. Currently, the placement in natural stone walls (marble, slate, granite, etc.), either indoors or outdoors, is done on the wall manually by placing each stone one by one, which must then be leveled to maintain a balance on the surface of the wall, preventing the stones protruding excessively from each other. Once the entire surface of the wall is covered, it is necessary to make a grout with cement of all the areas between each two stones, in addition if a more striking aspect is desired, a varnishing can be carried out to highlight the color of the stone.
La técnica de colocación, descrita anteriormente, resulta muy laboriosa por el hecho de que tener que seleccionar la piedra, colocar una a una nivelando sobre la paredyaveces realizar cortes en las piedras antes de colocar. The placement technique, described above, is very laborious due to the fact that having to select the stone, placing one at a level on the wall and sometimes making cuts in the stones before laying.
En la patente P200801757, de la que es adición la presente, se describía un procedimiento de fabricación de tableros, en diferentes medidas de espesor y tamaño, aprovechando cualquier trozo de piedra natural (mármol, granito, pizarra, calizas, cuarcitas o similar) o artificial. De tal forma que la colocación se limita a tener la pared perfectamente amaestrada y nivelada para colocar estos paneles como si fueran baldosas con la ventaja de ser un sistema rápido de colocar y con poca demanda de mano de obra. In the patent P200801757, of which the present is an addition, a method of manufacturing boards was described, in different thickness and size measurements, taking advantage of any piece of natural stone (marble, granite, slate, limestone, quartzite or similar) or arti fi cial. In such a way that the placement is limited to having the wall perfectly trained and leveled to place these panels as if they were tiles with the advantage of being a quick system of laying and with little demand for labor.

Detailed description and preferred embodiment of the invention
El procedimiento de fabricación de los tableros sigue las mismas fases descritas en la patente nº P200801757, con la salvedad de que en la fase 5, una vez preparada y vertida sobre los moldes la capa de mezcla de mortero (5), se aplicará el puente de unión de naturaleza química (6) a base de resinas de distinta naturaleza, sobre el material a colocar (1). El puente de unión tiene la capacidad de endurecer con la capa de mezcla de mortero (5), lo que permite insertar el material a colocar (1) y que quede anclado en el conjunto. The manufacturing process of the boards follows the same phases described in the patent No. P200801757, with the proviso that in phase 5, once the mortar mix layer (5) is prepared and poured onto the molds, the bridge will be applied of union of chemical nature (6) based on resins of different nature, on the material to be placed (1). The joint bridge has the ability to harden with the mortar mix layer (5), which allows the material to be placed (1) to be inserted and anchored in the assembly.
Los tableros obtenidos con este procedimiento también dispondrán de una malla de seguridad (4), metálica o plástica, y una base de mortero de cemento con aditivos (2) y un aislante termo-acústico (3), tal y como se describe en la patente nº P200801757. The boards obtained with this procedure will also have a safety mesh (4), metallic or plastic, and a cement mortar base with additives (2) and a thermo-acoustic insulator (3), as described in the Patent No. P200801757.
Esta nueva metodología permite la utilización tanto de cemento gris, como cemento blanco sin cromo a la hora de realizar el mortero base (5). Además, en el caso de utilizar cristal (coloreado o transparente), como material a colocar (1), el mortero base podrá ser coloreado mediante la incorporación de aditivos, con el objetivo de realzar el aspecto estético de los tableros. Sobre los cristales colocados, se podrán añadir figuras del tipo calcomanías transparentes o semitransparentes, o bien, tejidos de colores, unidos todos ellos al cristal mediante el uso del mismo puente de unión utilizado para colocar sobre el mortero base (5). This new methodology allows the use of both gray cement and white cement without chromium when making the base mortar (5). In addition, in the case of using glass (colored or transparent), as the material to be placed (1), the base mortar can be colored by incorporating additives, with the aim of enhancing the aesthetic appearance of the boards. On the placed crystals, fi gures of the type transparent or semi-transparent decals, or colored fabrics, all of them attached to the glass can be added by using the same connecting bridge used to place on the base mortar (5).
Para darle mayor resistencia mecánica al mortero base (5) y al mortero con el aislante (2), se podrá añadir a la mezcla una carga de micro-sílice (entre el 020% sobre la cantidad de cemento), reduciendo así, los áridos en función de la cantidad de micro-sílice añadida, y proporcionando al mortero mayor plasticidad y resistencia mecánica a la compresión y flexo-tracción. To give greater mechanical resistance to the base mortar (5) and to the mortar with the insulator (2), a load of micro-silica (between 020% on the amount of cement) can be added to the mixture, thus reducing aggregates depending on the amount of micro-silica added, and providing the mortar with greater plasticity and mechanical resistance to compression and fl exo-traction.
