Description
Tablero termoplástico autoportante para encofrado horizontal.Self-supporting thermoplastic board for horizontal formwork.
La presente memoria descriptiva se refiere a una solicitud de Patente de Invención, relativa a un tablero termoplástico autoportante para encofrado horizontal cuya finalidad reside en facilitar las tareas de encofrado y desencofrado mejorando las posibilidades de uso en obra debido a un menor peso, mayor resistencia, mayor durabilidad, y mejores características mecánicas que los tableros usados habitualmente.The present specification refers to an invention patent application, relating to a board self-supporting thermoplastic for horizontal formwork whose purpose resides in facilitating the formwork and formwork tasks improving the possibilities of use on site due to a lower weight, greater resistance, greater durability, and better characteristics mechanical than commonly used boards.
Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación de elementos de construcción en general, y en especial dentro de la industria de fabricación de tableros para encofrados. No se descarta que debido a las particulares cualidades de este tablero cuyas características principales reivindicamos más adelante, pueda ser usado en otros campos de la construcción, la decoración o la rehabilitación.This invention has its application within the industry dedicated to the manufacture of building elements in general, and especially within the manufacturing industry of formwork boards. It is not ruled out that due to particular qualities of this board whose characteristics main claims later, can be used in others fields of construction, decoration or rehabilitation.
Por parte del solicitante se tiene conocimiento de la existencia en la actualidad de una pluralidad de tableros de todo tipo y calidad que se utilizan en construcción para servir de encofrado.The applicant has knowledge of the existence at present of a plurality of boards of all types and quality that are used in construction to serve as formwork
La construcción por medio de encofrados es bastante antigua y se ha ido desarrollando paulatinamente para ir cubriendo las necesidades del mercado, que cada vez ha ido exigiendo elementos más eficaces, particularizados y sofisticados al objeto de ir paralelo al diseño de las construcciones.The construction by formwork is quite old and has been developing gradually to go covering the needs of the market, which has increasingly gone demanding more efficient, particularized and sophisticated elements in order to go parallel to the design of the constructions.
Son conocidos por parte del inventor un importante número de elementos de encofrado. Desde los más elementales tableros de madera hasta los más sofisticados constituidos por tableros de diferentes tipo de madera con o sin ceras en sus capas internas para mejorar el desencofrado.They are known by the inventor a significant number of formwork elements. From the most Elementary wooden boards to the most sophisticated constituted by boards of different types of wood with or without Waxes in their inner layers to improve formwork.
Casi todos los documentos de patente relativos a estos sistemas son ya de dominio público debido a la caducidad de la vida legal de las mismas.Almost all relative patent documents to these systems are already in the public domain due to the expiration of the legal life of them.
Pero en todo caso estos elementos difieren totalmente del objeto de la invención que se reivindica, superando la invención las características mecánicas, la resistencia a la flexo-tracción, mejorando el peso y por tanto su manejabilidad en obra, mejorando de forma importante la longevidad del material y sobre todo aportando la posibilidad del reciclado.But in any case these elements differ totally of the object of the invention that is claimed, surpassing The invention mechanical characteristics, resistance to flexo-traction, improving the weight and therefore its workability on site, significantly improving longevity of the material and especially providing the possibility of recycling.
Asimismo son conocidos tableros de encofrado metálicos, y tableros metálicos con elementos de madera.Formwork boards are also known metal, and metal boards with wooden elements.
También la invención propuesta mejora todas las características de estos tableros en todas las características antes reseñadas e incluso en el coste.Also the proposed invention improves all the characteristics of these boards in all the features previously reviewed and even in cost.
Desde principios de los años ochenta se ha intentado aportar por parte de la industria plástica de soluciones para tableros de encofrado que mejoran las condiciones mecánicas, de uso y de coste de las soluciones anteriores.Since the early eighties it has been tried to contribute by the solutions plastic industry for formwork boards that improve mechanical conditions, of use and cost of the previous solutions.
Dada la diversidad de soluciones, tan variadas como la múltiple diversidad de plásticos existentes, y cuya puesta en el mercado han sufrido diversas vicisitudes nos vamos a centrar en los antecedentes más recientes y que pudiesen ser tomados como antecedentes dentro de un informe sobre el estado de la técnica en relación con la solicitud de patente de referencia.Given the diversity of solutions, so varied as the multiple diversity of existing plastics, and whose setting in the market have suffered various vicissitudes we are going to focus in the most recent background and that could be taken as background within a report on the state of the art in relationship with the reference patent application.
Es conocida por el autor la patente alemana DE 41 37 649, que reivindica un elemento constructivo en forma de tablero formado por dos elementos de distintos módulos de elasticidad en forma de láminas, pudiendo estar constituida la interior por una aleación de aluminio.The German patent DE is known by the author 41 37 649, which claims a constructive element in the form of board formed by two elements of different modules of elasticity in the form of sheets, and the interior by an aluminum alloy.
Esta invención representa ya una mejora sobre los elementos constructivos realizados hasta entonces con maderas encoladas con resinas fenólicas, pero la complejidad de la fabricación, su alto coste y la dificultad de reciclado total han hecho que su uso no haya sido extendido.This invention already represents an improvement over the construction elements made until then with wood glued with phenolic resins, but the complexity of the manufacturing, its high cost and the difficulty of total recycling have made that its use has not been extended.
Además, su puesta en obra requiere un soporte metálico, ya que no se trata de tableros autoportantes.In addition, its implementation requires support metallic, since it is not self-supporting boards.
El inventor también conoce la patente alemana DE
197 24 361 que mejora la patente anterior, pero sólo en cuanto al
sistema de fabricación incorporando un dispositivo que permite la
fabricación en continuo, pero sigue teniendo los mismos problemas
que la anterior en cuanto a la unión entre los elementos plásticos
y/o termoplásticos y las capas de aleación de aluminio, asimismo
sus características mecánicas y de resistencia a los cambios de
temperatura pueden ser comprometidas, e idénticamente a la
anterior, requiere unos soportes metálicos para su puesta en
obra.The inventor also knows the German patent DE 197 24 361 which improves the previous patent, but only as regards the manufacturing system incorporating a device that allows continuous manufacturing, but still has the same problems as the previous one in terms of the union between the plastic and / or thermoplastic elements and the layers of aluminum alloy, also their mechanical characteristics and resistance to changes in temperature can be compromised, and identically to the previous one, it requires metal supports for its installation.
work.
También debemos considerar que al tratarse de un material de encofrado en obra deberían poder clavarse puntas, y en algún caso procederse a serrar de forma sencilla para una mejor adaptación, lo que es muy difícil en este tipo de tableros anteriormente descritos.We must also consider that when it comes to a formwork material on site should be able to nail points, and in some cases proceed to saw easily for better adaptation, which is very difficult in this type of boards previously described.
Por tanto consideramos que la invención que preconizamos mejora y supera ampliamente las características mecánicas y de uso de lo hasta ahora conocido, consiguiendo además un importante abaratamiento de los costes y siendo además objeto de una importante facilidad de reciclado, cualidad tan demandada en la moderna industria.Therefore we consider that the invention that We recommend improvement and widely exceed the characteristics mechanical and use of the hitherto known, also getting an important cost reduction and also being the subject of an important recycling facility, a quality so demanded in the Modern industry
