Adjustable joint for rectangular modules of hanging industrial platforms (Patent ES 2681962 B2)

The invention is a joining system for gilded metal modules manufactured with a rectangular tube profile and a final shape of the rectangular module, which joins a module with the one adjacent to the corners. This joint system is formed by a circular base with four countersunk holes through which four countersunk screws are joined and tighten the metal modules, connected to the short flange and the long flange. The short flange has a lower height so that it can be placed perpendicularly on top of the long flange, and thus be able to achieve a uniform tightening which entails a fixed and solid connection of the corresponding modules. When it is necessary to hang the rectangular modules in a point of the roof, said connection optionally comprises a support base of a strut, instead of the circular base piece, which makes it possible to connect the union with a strut.
