SOPORTE PARA DOBLE RED DE SEGURIDAD APLICABLE DURANTE LA CONSTRUCCIÓN DE EDIFICIOS Y SIMILARES SUPPORT FOR DOUBLE APPLICABLE SECURITY NETWORK DURING CONSTRUCTION OF BUILDINGS AND SIMILAR
D E S C R I P C I Ó ND E S C R I P C I Ó N
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente memoria descriptiva se refiere a una solicitud de una Patente de Invención, correspondiente a un soporte para doble red de seguridad aplicable durante la construcción de edificios y similares, cuya evidente finalidad estriba en configurarse como un soporte que en colaboración con una doble red de seguridad, potencia e implementa las redes de protección que se utilizan actualmente como elementos protectores durante la construcción de estructuras de hormigón armado para la configuración de edificios y similares .This specification refers to a request for an Invention Patent, corresponding to a support for double safety net applicable during the construction of buildings and the like, whose obvious purpose is to be configured as a support that in collaboration with a double network of safety, power and implements the protection networks that are currently used as protective elements during the construction of reinforced concrete structures for the configuration of buildings and the like.
La invención también tiene como finalidad, al margen de evitar la caída de los operarios, la de proteger a los viandantes que se desplacen por la zona donde se esta realizando la construcción del edificio o similar.The invention also aims, apart from preventing the fall of the operators, to protect pedestrians who move through the area where the construction of the building or the like is being carried out.
CAMPO DE LA INVENCIÓNFIELD OF THE INVENTION
Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación de aparatos, dispositivos y elementos de seguridad para la construcción en general.This invention has its application within the industry dedicated to the manufacture of apparatus, devices and safety elements for construction in general.
ANTECEDENTES DE LA INVENCIÓN El solicitante tiene conocimiento de que en la actualidad, las redes utilizadas durante la construcción de edificios y similares, concretamente durante la construcción de las estructuras con losas de hormigón armado, protegen a terceras personas de la caída accidental de materiales al exterior en tres plantas de trabajo.BACKGROUND OF THE INVENTION The applicant is aware that at present, the networks used during the construction of buildings and the like, specifically during the construction of the structures with reinforced concrete slabs, protect third parties from the accidental fall of materials abroad on three floors of job.
De igual modo, las citadas redes utilizadas actualmente protegen a los trabajadores en tres plantas , pero solamente a su nivel a los de la primera planta, no ocurriendo lo mismo a los que realizan los trabajos apropiados en la segunda y tercera de las tres plantas citadas, ya que estos si cayesen al vacío de forma accidental, tendrían el peligro de que al caer sobre las redes existiera un evidente peligro al golpearse con la propia estructura o elementos del encofrado situados en las plantas inferiores a las que protegen.Similarly, the aforementioned networks currently used protect workers on three floors, but only at the level of those on the first floor, the same not happening to those who perform the appropriate work on the second and third of the three plants mentioned , since if they accidentally fell into the void, they would have the danger that when falling on the nets there was an obvious danger when hitting with the structure or elements of the formwork located on the lower floors to which they protect.
También se ha constatado que tampoco queda protegida la caída del operario al exterior cuando se efectúan los trabajos de elevación de estas redes a unas alturas considerables en las plantas más altas.It has also been found that the fall of the operator abroad is not protected when the lifting works of these networks are carried out at considerable heights in the higher floors.
La solución evidente a esta problemática sería la de poder contar con dos redes independientes, a partir de las cuales el viandante que se desplaza por la zona inferior de la construcción, queda protegido de igual modo de la caída accidental de materiales, y a la vez con la utilización de las dos redes los operarios quedarán protegidos en las tres plantas de trabajo, ya que una red quedará a su mismo nivel, evitando caídas de una planta a la otra inferior. Sin embargo, por parte del solicitante, no se tiene conocimiento de la existencia en la actualidad de una invención que presente las características que se consideran como idóneas para realizar una protección integral ante la posibilidad de caída al vacío de materiales y operarios.The obvious solution to this problem would be to have two independent networks, from which the pedestrian that moves through the lower part of the construction, is protected in the same way from the accidental fall of materials, and at the same time with the use of the two networks operators will be protected in the three workplaces, since one network will remain at the same level, avoiding falls from one plant to the other lower. However, on the part of the applicant, there is no knowledge of the existence at present of an invention that presents the characteristics that are considered as suitable for full protection against the possibility of falling into vacuum of materials and operators.
