摘要

An improved method of construction of riveted joints, characterized essentially by starting from a cylindrical element provided with an axial cavity, whose diameter at its free end, is smaller than at the other end, which has an outer flange, said element being introduced into the inside the hole made in the joining area of the two plates, so that said flange coincides with the outer edge of the hole, then proceeding to the elastic deformation of the protruding end of the joint element, by the backward movement of a rod internally mounted therein, at the same time that a surrounding neck of said rod presses the flange of the joint element against the plates, in the opposite direction to that of displacement of the rod.
