Perfil para placa de encofrado.Profile for formwork plate.

Objeto de la invenciónObject of the invention

La siguiente invención, según se expresa en el enunciado de la presente memoria descriptiva, se refiere a un perfil para placa de encofrado, siendo del tipo de placas de encofrado que se adosan en horizontal y vertical en la materialización de la estructura de encofrado, quedando las placas fijadas entre sí por una serie de "grapas" para lograr su unión, de forma que el perfil perimetral que se describe tiene por objeto lograr una unión estanca y fiable sin que se produzcan deformaciones en el perfil perimetral de la placa que soporta la presión de unión entre las placas adosadas.The following invention, as expressed in the set forth herein, refers to a profile for formwork plate, being of the type of plates formwork that are attached horizontally and vertically in the materialization of the formwork structure, leaving the plates fixed to each other by a series of "staples" to achieve their union, so that the perimeter profile described has by object to achieve a tight and reliable union without them occurring deformations in the perimeter profile of the plate that supports the joint pressure between the attached plates.

Así, el perfil para placa de encofrado que se presenta tiene por objeto resolver el problema técnico que se produce en la unión adosada de las placas de encofrado provistas de un perfil perimetral hueco, ya que, al soportar estos la presión de unión entre las placas se produce su abollamiento de los perfiles perimetrales y consecuentemente la perdida de presión entre paneles por la debilidad de los perfiles perimetrales huecos.Thus, the profile for formwork plate that presents aims to solve the technical problem that produces in the attached connection of the formwork plates provided with a hollow perimeter profile, since, with these, the pressure of junction between the plates its denting of the profiles occurs perimeter and consequently the pressure loss between panels due to the weakness of the hollow perimeter profiles.

Campo de aplicaciónScope

En la presente memoria se describe un perfil para placa de encofrado, el cual es de aplicación para conformar el perfil perimetral de placas de encofrado, tanto de las placas que incorporan un panel fenólico como de las placas que incorporan una chapa metálica.A profile is described herein. for formwork plate, which is applicable to form the perimeter profile of formwork plates, both of the plates that they incorporate a phenolic panel as of the plates that incorporate a sheet metal

Antecedentes de la invenciónBackground of the invention

Como es conocido en el mercado existen una diversidad de placas de encofrado que, genéricamente, se constituyen por un perfil perimetral al que se fija un panel fenólico o una chapa metálica sobre los cuales se proyecta el hormigón, disponiendo el perfil perimetral de una serie de travesaños de refuerzo.As it is known in the market there is a diversity of formwork plates that are generically they constitute a perimeter profile to which a panel is fixed phenolic or a metal sheet on which the concrete, providing the perimeter profile of a series of reinforcement crossbars.

El perfil perimetral de las placas de encofrado puede materializarse por un perfil tubular de sección general rectangular que en su cara lateral presenta un entrante, de forma que en el adosamiento de las placas de encofrado su unión se lleva a cabo por medio de una serie de "grapas" de apriete constituidas por una pareja de brazos dotados de un saliente que encaja en los entrantes de los perfiles perimetrales de las placas a unir, materializando el apriete por medio de un cuerpo de cuña que aproxima los brazos de la "grapa" presionando sobre ambos perfiles de laminación general hueca.The perimeter profile of the formwork plates can be materialized by a tubular profile of general section rectangular that in its lateral face presents an entree, of form that the connection of the formwork plates is joined carried out by means of a series of "clamps" of tightening constituted by a pair of arms equipped with a projection that fits in the recesses of the perimeter profiles of the plates to join, materializing the tightening by means of a wedge body that Approach the arms of the "staple" by pressing on both General hollow lamination profiles.

Esta ejecución presenta el inconveniente de que al actuar presionando la cuña, los brazos de la "grapa" tienden a aproximarse aumentando la presión sobre los perfiles de las placas, de manera que al ser los perfiles huecos y ejercer sobre ellos una presión puntual se acaban abollando por la presión que sobre ellos transmiten las "grapas" hasta el punto de que la tensión de los brazos de la "grapa" disminuya llegando, incluso, a liberarse con el inconveniente que ello representa, ya que, la unión entre las placas no es la apropiada y al verter el hormigón, la presión que este ejerce puede hacer que las placas acaben distanciadas entre sí.This execution has the disadvantage that when acting by pressing the wedge, the arms of the "staple" tend to approximate by increasing the pressure on the profiles of the plates, so that being hollow profiles and exercising on them a punctual pressure is just dented by the pressure that on them transmit the "staples" to the point that the tension of the arms of the "staple" decrease coming, even, to free yourself with the inconvenience that this represents, and that, the union between the plates is not appropriate and when pouring the concrete, the pressure it exerts can make the plates end up distanced from each other.
