  • Patent number: 5079891
    Abstract: A bidimensional support or tower for overhead electric energy transmission lines is formed of a flat truss structure, the stringers of which consist of at least one truss beam comprising a pair of cold-bent channel sections connected together, with their cavities facing, by means of a zigzag-bent steel rod applied by welding to the flanges of said sections. Said tower comprises two stringers connected by one or more horizontal girders, which stringers can be vertical and parallel, or else converging towards the top substantially in correspondence of the point where the loads are applied, in which latter case a vertical structural element is provided above said point. Said stringers and said vertical structural element are formed of said truss beams, positioned either singly or side-by-side.
