Abstract

Joining node for rigid structures, characterized in that it is constituted by metal pieces at right angles, engageable in tubular bars of rectangular profile open or closed, provided with rows of holes on a larger side, elongated along the longitudinal direction of the side itself, and another row of holes on the smaller sides, in which said coupling parts have one of their wings joined perpendicularly, on the outside face, to a crossbeam with a supporting function, while the remaining wing has a perpendicular fold protruding from the outside. Inner side, three hooks in mutual alignment, which correspond to respective correlative holes on the long side of the bar, whose hooks form a projection on the lower part, while the upper coupling also has a projection on the upper part, so that the practicable assembly between a piece and a bar takes place by application of the first the second, in angular juxtaposition, facing its hooks with the corresponding holes on the long side of the bar, introducing first said upper protrusion and running the piece upwards to allow free penetration of the three hooks in the holes by rotation of the piece, after which the latter moves downwards so that the lower protrusions are assembled and supported on the bar, optionally holding the coupling piece by means of a screw passed through the hole of its wing attached to the crosspiece, and by one of the holes on the smaller opposing side of the bar, and with pressed by a nut.
