Component for support structure

Abstract

In a component for supporting structures, a central body with a passing axial hole has on a front external wall and a rear external wall a first front seat and a first rear seat, accessible from outside and symmetrical with a first longitudinal symmetry plane of the body. Other external walls of the central body, namely a right external wall and a left external wall, have respectively a second right seat and a second left seat, accessible from the outside and symmetrical with respect to a second longitudinal symmetry plane extending at right angles to the first longitudinal symmetry plane of the central body.
