Description
Unión de bandejas portacables Union of cable trays
Objeto de la invención Object of the invention
La presente invención tiene por objeto un sistema de unión de bandejas portacables de rejilla en la que dicha unión se realiza aprovechando la elasticidad de las alas de la bandeja. The present invention has as its object a system for joining grid cable trays in which said connection is made taking advantage of the elasticity of the wings of the tray.
Según la invención, las bandejas comprenden en uno de sus extremos unas piezas de unión que presentan dos porciones, una primera porción fijada de modo permanente a uno de los extremos de una de las bandejas, y una segunda porción que ejerce la función de guía durante el montaje, y bloqueo de la otra bandeja una vez alcanzada la posición final de la unión. According to the invention, the trays comprise at one of their ends connecting pieces having two portions, a first portion permanently fixed to one of the ends of one of the trays, and a second portion that exerts the guiding function during the assembly, and blocking of the other tray once the final position of the union is reached.
Una vez ensamblado el sistema asegura una retención óptima de las varillas así como un bloqueo de giros y desplazamientos sin precisar elementos adicionales tales como herramientas u otros elementos de fijación. Once assembled the system ensures optimum retention of the rods as well as a blockage of turns and displacements without requiring additional elements such as tools or other fasteners.
Estado de la técnica State of the art
Existen diferentes modos de unión de bandejas entre sí. Tradicionalmente las bandejas de rejilla se han unido entre sí mediante la utilización de tornillos, tuercas, y arandelas; estos sistemas requieren una gran cantidad de mano de obra para el montaje, por lo que la productividad resulta insatisfactoria. Además, la seguridad en el montaje tampoco es satisfactoria por cuanto puede haber deslizamientos durante el montaje o a causa de la carga que soporta, o bien por no haberse apretado suficientemente la tornillería. La
seguridad se ha solucionado utilizando arandelas deformadas, grapas o piezas especialmente concebidas para abrazar al menos dos varillas, quedando estas confinadas entre dichas piezas y el tornillo o tuerca de apriete. Sin embargo, el montaje de bandejas con este tipo de unión requiere que el operario sujete la bandeja al mismo tiempo que coloca los elementos de sujeción, lo que resulta difícil o requiere de un segundo operario para esa sujeción. There are different ways of joining trays to each other. Traditionally the grid trays have joined together by using screws, nuts, and washers; These systems require a large amount of labor for assembly, so productivity is unsatisfactory. In addition, the safety in the assembly is not satisfactory either because there may be sliding during assembly or because of the load it supports, or because the hardware has not been sufficiently tightened. The safety has been solved using deformed washers, staples or pieces specially designed to embrace at least two rods, these being confined between said parts and the tightening screw or nut. However, the assembly of trays with this type of joint requires that the operator hold the tray at the same time that he places the fasteners, which is difficult or requires a second operator for that support.
EP 0973238 describe un canal de cables de rejilla, en el que uno de sus extremos presenta un estrechamiento con respecto al otro de los extremos, de modo que al menos una varilla transversal es introducida entre una pareja de varillas transversales del extremo opuesto de otro canal igual. Dicha sujeción puede realizarla un único operario y dejar ese canal (o bandeja) suspendido sobre el precedente hasta que realice la fijación correspondiente, ya que la mera inserción resultará inestable. EP 0571307 describe también un dispositivo de sujeción de bandejas de rejilla que comprende unas proyecciones laterales dispuestas a cada uno de los lados de la bandeja en uno de sus extremos, de modo que dichas proyecciones pueden insertarse entre una pareja de varillas longitudinales de la bandeja precedente, con una pestaña de sujeción en el extremo de dichas proyecciones que se sujeta elásticamente contra una de las varillas transversales que conforman dicha bandeja.
