摘要

Improvements introduced in the systems of mixed structures, starting from the principle of using, for the construction of a structure, beams of loads formed by a metallic profile, a concrete head and connecting elements, these latter secured to the metallic profile and embedded in the concrete, said parts being combined in such a way that the metallic profile absorbs the tensile stresses, the concrete head, the compression heads, and the cutting connectors, are essentially characterized by the fact that the connectors are constituted by a single elongated piece, of circular or polygonal section and folded so as to originate a succession of U-shaped branches, divergent, each of them related to its contiguous through straight sections parallel to the central sections of the u and occasionally shorter than these, which piece is welded through the repeated central sections of the u on the line i longitudinal diameter of the upper part of the metal profile, so that it extends perpendicularly from there, and has the particularity that its adherence length is considerably equal to or greater than 30 times the minimum measurement of the round.
