DISPOSITIVO PARA FIJAR Y ASEGURAR UNA ESTRUCTURA DE ENCOFRADODEVICE FOR FIXING AND SECURING A STRUCTURE OF FORMWORK
DESCRIPCIONDESCRIPTION
Objeto de la invencionObject of the invention
La presente invencion se refiere a un dispositivo para fijar y asegurar una estructura de encofrado, preferentemente un encofrado modular, y mas preferentemente un encofrado modular para la construction de vigas de cuelgue.The present invention relates to a device for fixing and securing a formwork structure, preferably a modular formwork, and more preferably a modular formwork for the construction of hanging beams.
Problema tecnico a resolver y antecedentes de la invencionTechnical problem to solve and background of the invention
En la actualidad son conocidos distintos sistemas para fijar y asegurar estructuras de encofrados empleados para hormigonar la parte de estructura horizontal que une dos pilares. Estas estructuras de encofrado incorporan un travesano superior que es el que soporta el peso de la masa de hormigon durante el vertido del hormigon y su fraguado posterior. El travesano superior se apoya mediante una sucesion de puntales dispuestos en el mismo plano vertical que los pilares.At present, different systems are known for fixing and securing formwork structures used to concrete the part of the horizontal structure that joins two pillars. These formwork structures incorporate an upper crossbar that is the one that supports the weight of the concrete mass during the pouring of the concrete and its subsequent setting. The upper cross is supported by a succession of struts arranged in the same vertical plane as the pillars.
Los puntales empleados para que se apoye el travesano superior, tambien se utilizan para fijar una plataforma de trabajo a la que acceden unos operarios para trabajar sobre la masa de hormigon y tambien para colocar las distintas piezas del encofrado.The props used to support the upper crossbar are also used to fix a work platform that is accessed by operators to work on the concrete mass and also to place the different pieces of the formwork.
Este sistema de fijacion de la estructura de encofrado y de la plataforma de trabajo, a veces es inestable y poco fiable, ya que la totalidad del sistema de fijacion esta vinculado exclusivamente a los puntales, los cuales no estan asociados a ninguna estructura fija, como podrlan ser los pilares.This system of fixing the formwork structure and the work platform is sometimes unstable and unreliable, since the entire fixing system is linked exclusively to the struts, which are not associated with any fixed structure, such as They could be the pillars.
Es necesario aportar a los operarios que estan trabajando sobre la plataforma de trabajo una superficie en la que la estabilidad y la sensation de firmeza sean percibidas por dichos operarios, ya que el movimiento en el plano horizontal en forma de oscilacion transmite una sensacion de inestabilidad con la que los operarios encuentran mayor dificultad para desarrollar su labor.It is necessary to provide to the workers who are working on the work platform a surface in which the stability and firmness sensation are perceived by said operators, since the movement in the horizontal plane in the form of oscillation transmits a sensation of instability with which operators find greater difficulty in developing their work.
