Description

Mástil de soporte para redes de obra.Support mast for work networks.

Object of the invention

La presente invención se refiere a un mástil que ha sido especialmente concebido como soporte, fijable al perímetro de un forjado, para sustentación de una red de protección de las utilizadas durante el desarrollo de la obra.The present invention relates to a mast that It has been specially conceived as a support, fixed to the perimeter of a floor, to support a network of protection of used during the development of the work.

El objeto de la invención es conseguir un mástil, de gran solidez estructural, capacitado para variar su longitud efectiva y para asegurar una fácil, rápida y segura fijación al mismo de la red a soportar.The object of the invention is to achieve a mast, of great structural strength, able to vary its length effective and to ensure an easy, fast and safe fixation to the same network to support.

Background of the invention

Como es sabido, durante la construcción de un edificio de mayor o menor altura, se utilizan redes de protección que se adaptan al perímetro de la obra y que con una altura considerable, que normalmente es de nueve metros, y en paños del orden de veinticinco metros de largo, constituye una barrera de protección que, sin restar visibilidad entre el interior y el exterior de la obra, actúan como amortiguador frente a posibles caídas tanto de personas como de objetos, evitando lesionas para las primeras, y que los objetos puedan a su vez lesionar a personas situadas a nivel del suelo.As is known, during the construction of a building of greater or lesser height, protection nets are used that adapt to the perimeter of the work and that with a height considerable, which is normally nine meters, and in cloths of twenty-five meters long, it constitutes a barrier of protection that, without diminishing visibility between the interior and the outside of the work, they act as a buffer against possible falls of both people and objects, avoiding injuries to the first, and that objects can in turn injure people located at ground level.

Para la sustentación de dichas redes se utilizan mástiles metálicos, de configuración en "L" invertida, de manera que dichos mástiles se fijan al forjado por la extremidad libre de su rama mayor y sustentan la red por la extremidad libre de su rama menor, la cual se monta proyectada hacia el exterior de la obra.For the support of these networks are used metal masts, inverted "L" configuration, of so that said masts are fixed to the forged by the limb free of its major branch and support the network by the free limb of its minor branch, which is mounted projected outwards of the play.

Estos mástiles constituyen a veces un estorbo en determinadas manipulaciones o trabajos realizados en el seno de la obra, resultan en cualquier caso pesados y difíciles de manipular, y en ocasiones originan problemas a la hora de fijar la red, a lo que hay que añadir además que sus dimensiones preestablecidas y fijas no permiten adecuar el nivel de sustentación en altura de las redes a la cota requerida en cada caso.These masts sometimes constitute a hindrance in certain manipulations or work done within the work, they are in any case heavy and difficult to manipulate, and sometimes they cause problems when setting up the network, at which must also be added that its preset dimensions and fixed do not allow to adjust the level of support in height of the networks at the required level in each case.

Description of the invention

El mástil que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados.The mast proposed by the invention resolves from the problem was fully satisfactory before exposed, in the different aspects commented.

Para ello y de forma más concreta, dicho mástil está constituido mediante un cuerpo tubular, de acero, preferentemente de sección cuadrangular, dotado de dos acodamientos obtusos y contrapuestos, que determina dos tramos extremos, paralelos y sensiblemente desfasados, en una magnitud del orden de 800 milímetros, relacionados entre sí mediante un tramo oblicuo que distancia convenientemente el tramo superior del inferior, o lo que es lo mismo, que distancia convenientemente el tramo superior del borde de la fachada, para que no interfiera en los trabajos a realizar sobre el forjado superior a que o sobre el que se monta el mástil.To do this and more specifically, said mast it is constituted by a tubular body, of steel, preferably quadrangular section, equipped with two couplings obtuse and conflicting, which determines two extreme sections, parallel and noticeably out of date, in a magnitude of the order of 800 millimeters, related to each other by an oblique section that conveniently distance the upper section from the lower one, or what it is the same, that distance conveniently the upper section of the edge of the facade, so that it does not interfere in the work to perform on the upper floor than or on which the mast.

Como complemento de la estructura descrita el citado mástil tubular incorpora en su extremidad superior y en su inflexión obtusa inferior, sendas semi-argollas debidamente soldadas al mismo, para facilitar el atado o fijación de la red.As a complement to the structure described on said tubular mast incorporates in its upper extremity and in its lower obtuse inflection, semi-ring paths duly welded to it, to facilitate tying or fixing of the network.

El mástil así estructurado, con una longitud efectiva de cinco metros, puede ser transformado en un mástil de siete metros mediante la colaboración de una pieza accesoria, materializada también en un tubo de sección cuadrangular y de acero, como el anterior, pero en este caso rectilíneo, en el que su extremo superior presenta un ensanchamiento asimismo tubular, que permite el acoplamiento machihembrado a la extremidad inferior del mástil principal, para alargar la altura efectiva de éste último, de manera que de la cota de cinco metros anteriormente citada se pasa a una cota global de siete metros.The mast thus structured, with a length effective five meters, can be transformed into a mast of seven meters through the collaboration of an accessory piece, also materialized in a quadrangular section tube and steel, like the previous one, but in this case rectilinear, in which its upper end has an equally tubular widening, which allows tongue and groove coupling to the lower extremity of the main mast, to extend the effective height of the latter, so that the aforementioned five-meter elevation is passes to a global elevation of seven meters.
