TABLERO DE ENCOFRADO DE UNA SOLA PIEZA DE MATERIAL COMPUESTO SINGLE BOARD OF SINGLE PIECE OF COMPOSITE MATERIAL
CAMPO DEL INVENTOFIELD OF THE INVENTION
DD
El presente invento se refiere a un tablero de enco¬ frado de una sola pieza a base de material compuesto, esto es, material conocido habitualmente con el término genérico inglés de "composite". Este tablero es adecuado para la cons- 0 trucción de pisos, paredes, techos, suelos, vigas y otros elementos de edificación tanto de viviendas como de obras civiles.The present invention relates to a single-piece encoding board based on composite material, that is, material commonly known with the generic English term "composite." This board is suitable for the construction of floors, walls, ceilings, floors, beams and other building elements of both houses and civil works.
ANTECEDENTES 5BACKGROUND 5
El uso de encofrados en la construcción de edificios y otras obras civiles es muy antiguo, habiéndose recurrido a diversos materiales y estructuras para la obtención de tales encofrados. Tradicionalmente, los encofrados se han venido 0 fabricando en madera, metal o incluso papel y, más reciente¬ mente, se ha incorporado también el uso de los materiales plásticos. Así, por ejemplo, en el Modelo de Utilidad nΩ 269.766 se describe un encofrado perdido que comprende una chapa metálica con ondulaciones a modo de canales paralelos, 5 en el Modelo de Utilidad nΩ 273.076 se utiliza una combina¬ ción de listones unitarios encolados longitudinalmente unos a otros y varillas metálicas que los atraviesan, en el Modelo de Utilidad nΩ 281.859 se cubre un elemento de encofrado para construcción de hormigón que comprende dos planchas de plás- 0 tico celular duro verticales unidas rígidamente entre sí por medio de almas transversales verticales, en el Modelo de Utilidad nΩ 285.924 se protege una unidad de encofrado a fondo perdido que está constituida por un cuerpo tubular cilindrico integrado por una pluralidad de bandas de papel 5 arrolladas helicoidal ente e impregnadas con resina, en el Modelo de Utilidad n2 287.749 se describe un encofrado perdi¬ do que comprende un panel de material plástico expandido dotado de corrugaciones paralelas y de redes metálicas de refuerzo, en el Modelo de Utilidad nΩ 289.183 se cubre una placa de encofrado constituida por un bastidor metálico y una tabla alojada dentro del mismo, y en el Modelo de Utilidad nΩ 8700016 se describe un encofrado modular que comprende un marco metálico de rigidización asistido por una pluralidad de costillas o travesanos intermedios.The use of formwork in the construction of buildings and other civil works is very old, having used various materials and structures to obtain such formwork. Traditionally, formwork has been made or manufactured in wood, metal or even paper and, more recently, the use of plastic materials has also been incorporated. Thus, for example, in the Utility Model nΩ 269.766 a lost formwork is described comprising a metal sheet with undulations as parallel channels, 5 in the Utility Model nΩ 273.076 a combination of longitudinally glued unit slats is used. to others and metal rods that pass through them, in the Utility Model nΩ 281.859 a formwork element for concrete construction is covered comprising two vertical hard plastic plastic plates rigidly joined together by means of vertical transverse souls, in Utility Model nΩ 285.924 protects a lost bottom formwork unit consisting of a cylindrical tubular body composed of a plurality of paper strips 5 wound and impregnated with resin, in Utility Model No. 287.749 a lost formwork comprising an expanded plastic panel provided with parallel corrugations and metal reinforcement nets, in the Utility Model nΩ 289.183 a formwork plate consisting of a metal frame and a board housed therein is covered, and in the Utility Model nΩ 8700016 a modular formwork is described comprising a metal stiffening frame assisted by a plurality of ribs or intermediate crossbars.
Todos los encofrados a que antes se ha aludido como ejemplos de la técnica anterior, adolecen del defecto de presentar una estructura bastante complicada que encarece notablemente su fabricación. Por tanto, existe la necesidad de diseñar un nuevo tipo de encofrado que, conservando las características de resistencia mecánica y duración requeri¬ das, ofrezca una estructura más sencilla y, por tanto, con- tribuya a un sensible abaratamiento de los costes de fabrica¬ ción. Ξs aquí precisamente donde interviene el presente in¬ vento.All the forms that have been referred to as examples of the prior art, suffer from the defect of presenting a rather complicated structure that makes its manufacture significantly more expensive. Therefore, there is a need to design a new type of formwork that, while maintaining the required mechanical strength and durability characteristics, offers a simpler structure and, therefore, contributes to a sensible lowering of manufacturing costs. tion. This is precisely where the present invention intervenes.
SUMARIO DEL INVENTOSUMMARY OF THE INVENTION
El presente invento tiene como objeto superar las deficiencias αe los encofrados de la técnica anterior median¬ te la sustitución de la madera tradicionalmente empleada como material básico por un material más idóneo de características mecánicas mejoradas, y, a este fin, ha creado un nuevo table¬ ro de encofrado de una sola pieza a base de material compues¬ to, que está formado por un cuerpo de envoltura de plástico moldeado que determina la configuración exterior del tablero y una serie de refuerzos internos que van empotrados en el plástico del tablero.The present invention aims to overcome the deficiencies αe the formwork of the prior art by replacing the wood traditionally used as a basic material with a more suitable material with improved mechanical characteristics, and, to this end, has created a new table One-piece formwork based on composite material, which is formed by a molded plastic wrap body that determines the outer configuration of the board and a series of internal reinforcements that are embedded in the board's plastic.
Preferiblemente, los refuerzos internos consisten en una o más barras metálicas y o en una o más tablas de madera. Como metal para las barras se emplea preferiblemente el acero corrugado u otro metal de características mecánicas semejan- tes y como plástico de envoltura se utiliza una poliolefina, en particular un polietileno de alta o baja densidad.Preferably, the internal reinforcements consist of one or more metal bars and or one or more wooden boards. Corrugated steel or other metal of similar mechanical characteristics is preferably used as the metal for the bars and a polyolefin, in particular a high or low density polyethylene, is used as the wrapping plastic.
Las barras metálicas y las tablas de madera pueden _ _> _ adoptar diversas posiciones dentro del tablero.Metal bars and wooden boards can _ _> _ adopt various positions within the board.
Así, es posible que tanto las barras metálicas como las tablas de madera vayan dispuestas en posición horizontal o en posición vertical. Asimismo, es factible disponer las barras y las tablas de manera que unas barras y tablas hori¬ zontales alternen con otras barras y tablas verticales, pro¬ duciendo así una especie de enrejado interno. Igualmente, las barras y las tablas pueden disponerse oblicuamente con rela¬ ción a los lados del tablero, siendo posible también que las barras y tablas oblicuas se entrecrucen definiendo una espe¬ cie de enrejado interno.Thus, it is possible that both the metal bars and the wooden boards are arranged horizontally or vertically. Likewise, it is feasible to arrange the bars and tables so that horizontal bars and tables alternate with other vertical bars and tables, thus producing a kind of internal lattice. Likewise, the bars and the boards can be arranged obliquely in relation to the sides of the board, it is also possible that the bars and oblique boards intersect defining an internal lattice species.

DESCRIPCIÓN D_ETA LAPA DE LOS DIBUJOSDESCRIPTION D_ETA LAPA OF THE DRAWINGS
Haciendo referencia a los dibujos, se ha ilustrado en ellos un tablero de encofrado 1 de configuración rectangu¬ lar en planta y de sección transversal también rectangular, aun cuando, como se comprenderá, sería posible adoptar otras configuraciones del tablero de encofrado de conformidad con las necesidades de cada caso. Asimismo, el tablero 1 podría ser plano o curvo.Referring to the drawings, there is illustrated a formwork board 1 of rectangular configuration in plan and also of rectangular cross-section, although, as will be understood, it would be possible to adopt other configurations of the formwork board in accordance with the needs of each case. Also, board 1 could be flat or curved.
El tablero de encofrado 1 está constituido por un cuerpo de envoltura 2 de material plástico moldeado, dentro del cual van alojados unos componentes de refuerzo y armadura constituidos por barras metálicas 3 y tablas de madera 4. Las barras metálicas 3 son preferiblemente de acero corrugado, aun cuando podría utilizarse cualquier otro metal adecuado de características mecánicas semejantes a las del acero. La sec¬ ción transversal de estas barras 3 se ha representado como circular, pero sería posible adoptar cualquier otra configu¬ ración apropiada. El plástico del cuerpo de envoltura 2 se elegirá preferiblemente dentro del grupo de las poliolefinas, contemplándose en especial el empleo de polietileno de altaThe formwork board 1 is constituted by a wrapping body 2 of molded plastic material, within which reinforcement and reinforcement components consisting of metal bars 3 and wooden boards 4 are housed. Metal bars 3 are preferably of corrugated steel, even if any other suitable metal of mechanical characteristics similar to those of steel could be used. The cross section of these bars 3 has been represented as circular, but it would be possible to adopt any other appropriate configuration. The plastic of the wrapping body 2 will preferably be chosen from the group of polyolefins, especially the use of high polyethylene.

No obstante, sería posible utilizar cual- quier otro material plástico, siempre que sea capaz de resis¬ tir las duras condiciones de trabajo que habitualmente reinan en las obras de construcción.0 low density. However, it would be possible to use any other plastic material, provided that it is able to withstand the harsh working conditions that usually reign in construction sites.
Ξn el ejemplo de realización elegido, tanto las ba¬ rras metálicas 3 como las tablas de madera 4 se han represen- tado dispuestas en posición horizontal y paralelas unas a otras. No obstante, sería posible elegir otras disposiciones dentro de un amplio abanico de ellas, con la única condición de que sirvan como refuerzo y armadura adecuados del tableroIn the chosen embodiment, both the metal bars 3 and the wooden boards 4 have been shown arranged horizontally and parallel to each other. However, it would be possible to choose other provisions within a wide range of them, with the sole condition that they serve as adequate reinforcement and reinforcement of the board
1 y no incrementen sensiblemente su peso ni su coste. Así, por ejemplo, sería posible disponer las barras 3 y las tablas1 and do not significantly increase its weight or cost. Thus, for example, it would be possible to arrange the bars 3 and the tables
4 en posición vertical o en posición oblicua con respecto a los lados del tablero 1.4 vertically or obliquely with respect to the sides of the board 1.
Igualmente, una disposición apropiada consistiría en alternar barras 3 y tablas 4 horizontales con otras barras y tablas colocadas en posición vertical, con lo cual se produ¬ ciría un entrecruzamiento de barras y tablas que daría lugar a la obtención de una especie de enrejado interno.Likewise, an appropriate arrangement would consist of alternating horizontal bars 3 and tables 4 with other bars and tables placed vertically, whereby a cross-linking of bars and tables would occur which would result in obtaining a kind of internal lattice.
De la misma manera, sería posible que unas barras 3 y tablas 4 oblicuas se entrecruzaran con otras barras y ta- blas igualmente oblicuas, dando lugar también a la obtención de un enrejado interno.In the same way, it would be possible for bars 3 and oblique boards 4 to intersect with other bars and tables equally oblique, also resulting in obtaining an internal lattice.
Por consiguiente, como podrá apreciarse, son muy variadas las posibilidades de ejecución del tablero de enco¬ frado del invento, todas las cuales tienen las ventajas si- guientes: mayor número de aplicaciones del tablero, con lo que, aparte de incrementar su duración, se disminuyen costes y se evita consumo innecesario de madera; mejor calidad de - zz¡ - acabado, ya que el tablero del invento permite obtener un acabado directo sin necesidad de rasear; ausencia de defor¬ maciones por efecto del agua, lo cual contrasta con lo que ocurre en los encofrados de madera; máxima seguridad de uti- lización, ya que el tablero de encofrado del invento consiste en una pieza enteriza que no está formada por partes al modo de las tablas que conforman el tablero de madera convencio¬ nal; mayor precisión en la fijación del perfil metálico al tablero, lo cual alarga la duración al aumentar la resisten- cia frente a los choques; y, como compendio, mejoras caracte¬ rísticas mecánicas del tablero del invento en comparación con los tableros convencionales.Therefore, as can be seen, the possibilities of executing the encoding board of the invention are varied, all of which have the following advantages: greater number of applications of the board, which, apart from increasing its duration, costs are reduced and unnecessary consumption of wood is avoided; best quality of - zz ¡ - finish, since the board of the invention allows to obtain a direct finish without the need to scratch; absence of deformations due to the effect of water, which contrasts with what occurs in wooden formwork; maximum safety of use, since the formwork board of the invention consists of an integral piece that is not formed by parts in the manner of the boards that make up the conventional wooden board; greater precision in fixing the metal profile to the board, which lengthens the duration by increasing the resistance against shocks; and, as a compendium, mechanical characteristic improvements of the board of the invention compared to conventional boards.
