DE ENCOFRADO PARA EJECUCIÓN DE UN MURO DE HORMIGÓN FORMWORK FOR THE EXECUTION OF A CONCRETE WALL
DESCRIPCIÓN DESCRIPTION
Campo de la invención Field of invention
Es objeto de la invención un dispositivo para colocación de paneles de encofrado para ejecución de un muro de hormigón que permite realizar la colocación del encofrado desde un lado del muro sin necesidad de tener acceso por los dos lados del muro, facilitando así la labor de colocación del encofrado para posterior hormigonado del muro. La invención es de aplicación en la industria de la construcción, tanto en obra civil como en edificación. The object of the invention is a device for placing formwork panels for the construction of a concrete wall, which allows the placement of the formwork from one side of the wall without the need to have access from both sides of the wall, thus facilitating the work of placing the formwork for subsequent concreting of the wall. The invention is applicable in the construction industry, both in civil engineering and in building.
Problema técnico a resolver y antecedentes de la invención Technical problem to be solved and background of the invention
En la ejecución de muros de hormigón es necesario montar una estructura que retenga el hormigón en su interior cuando se realiza el hormigonado del muro es decir cuando se vierte el hormigón en estado fresco hasta que adquiere la consistencia que le permite mantenerse por sí mismo. When constructing concrete walls, it is necessary to assemble a structure that retains the concrete inside when the wall is being concretized, that is, when the fresh concrete is poured until it acquires the consistency that allows it to stand on its own.
Los encofrados de los muros constan de dos caras enfrentadas en cuyo interior se sitúa el hormigón, de modo que, con los sistemas conocidos en el estado de la técnica, es necesario acceder a los dos lados del muro para colocar los elementos que configuran el encofrado. Este acceso a los dos lados del muro implica, en caso de que el muro tenga una altura elevada la utilización de medios auxiliares que permita alcanzar la posición de colocación de los elementos que configuran el encofrado. Wall formwork consists of two facing sides, inside which the concrete is placed, so that, with the systems known in the state of the art, it is necessary to access both sides of the wall to place the elements that make up the formwork. This access to both sides of the wall implies, in the case of a high wall, the use of auxiliary means that allow reaching the position of placement of the elements that make up the formwork.
Los encofrados tradicionalmente están compuestos por una barra roscada que sirve de apoyo a una tuerca extrema y una pieza de apoyo, tal que entre la tuerca extrema y la pieza de apoyo se sitúa una placa de encofrado que es la que estará en contacto con el hormigón, y tal que la pieza de apoyo se queda posteriormente embebida en el propio muro una vez se ha realizado el hormigonado del mismo. Traditionally, formwork is made up of a threaded bar that supports an end nut and a support piece, such that between the end nut and the support piece there is a formwork plate that is the one that will be in contact with the concrete, and such that the support piece is subsequently embedded in the wall itself once the concreting has been carried out.
A la hora de reducir costes en la ejecución de muros una manera es realizar el acceso al mismo desde un único lado del muro, evitando así la necesidad de emplear estructuras auxiliares por los dos lados del muro, lo que reduce el tiempo de ejecución y el coste asociado tanto a la estructura como al tiempo. When it comes to reducing costs in the construction of walls, one way is to access it from only one side of the wall, thus avoiding the need to use auxiliary structures on both sides of the wall, which reduces the construction time. and the cost associated with both structure and time.
Son conocidos dispositivos similares que emplean distintos sistemas de conexión entre sus elementos sin proporcionar una conexión estanca entre los elementos y los paneles de encofrado tan segura y sencilla como la que realiza el dispositivo objeto de la invención, como por ejemplo el que aparece reflejado en el documento EP3553253B1. Similar devices are known that use different connection systems between their elements without providing a watertight connection between the elements and the formwork panels as safe and simple as that provided by the device object of the invention, such as the one reflected in document EP3553253B1.
