Objeto de la invenciónObject of the invention

El objeto del invento se encuadra en el sector técnico de los medios de protección provisional en obras de construcción, para proteger a objetos y personas mientras la obra no está terminada. Se refiere a un dispositivo para retener la caída a distinto nivel en obras de construcción y, mas en concreto, a un sistema de sustentación de redes de seguridad, plegable y ajustable tanto en longitud como en inclinación, que se instala en las estructuras de edificios en construcción. The invention falls within the technical field of temporary fall protection devices for construction sites, designed to protect objects and people while the work is under construction. It relates to a device for arresting falls from heights on construction sites and, more specifically, to a foldable and adjustable safety net support system, both in length and inclination, which is installed on the structures of buildings under construction.

Antecedentes de la invenciónBackground of the invention

En el actual estado de la técnica ya se conocen sistemas de sustentación que tienen la misión de soportar las redes de seguridad utilizadas a lo largo del perímetro del forjado de cada una de las plantas de una obra, de modo que no puedan caer al vacío objetos o personas en edificios en construcción pudiendo citarse, por ejemplo y entre otros, los documentos ES1300546, ES1071635, ES1071632 y ES1284934. In the current state of the art, support systems are already known that have the mission of supporting the safety nets used along the perimeter of the floor slab of each of the floors of a building, so that objects or people cannot fall into the void in buildings under construction, for example and among others, the documents ES1300546, ES1071635, ES1071632 and ES1284934 can be cited.

Problema técnico a resolverTechnical problem to be solved

Problemas técnicos de los sistemas de sustentación conocidos (como, por ejemplo, los descritos en los documentos ES1071635 y ES1284934) es que no ofrecen la posibilidad de distintas inclinaciones en la parte superior. A technical problem with known support systems (such as those described in documents ES1071635 and ES1284934) is that they do not offer the possibility of different inclinations at the top.

Problemas técnicos de los sistemas de sustentación conocidos que si ofrecen la posibilidad de distintas inclinaciones en la parte superior (como, por ejemplo, los descritos en los documentos ES1071632 y ES1300546) es que presentan una estructuración compleja y su montaje/desmontaje complicado aumenta considerablemente los tiempo de mano de obra empleados en estas labores. Technical problems of known support systems that do offer the possibility of different inclinations at the top (such as, for example, those described in documents ES1071632 and ES1300546) are that they have a complex structure and their complicated assembly/disassembly considerably increases the labor time spent on these tasks.
