ABSTRACT:
A system for making spatial structures includes connecting pieces for attaching structural rods. The connection pieces include a central body whereupon two superimposed crowns of lugs are arranged, the lugs of one crown being angularly shifted with respect to those of the other crown. The middle axes of the lugs of the two crowns intersect in one same point situated on the axis of the central body. Such is the geometry of the lugs that they may be pierced in a certain zone as required according to the application contemplated, by using center holes for materializing the central body axis and a reference basis.
