Abstract
Knot for structures, characterized in that it is constituted by a core formed by a regular solid body, as a conjunction element, in whose periphery it has radially, in orthogonal senses, scraped blind holes, and by tubular bars, acting as right feet and of load-bearing elements, whose ends are applied in the aforementioned holes and are fastened to the cores themselves by means of hollow connectors, with external threading and flexure slots in radial and axial planes, so that, being of slight external conicity those mentioned and with larger diameter in its back slightly larger than the hole, its tight produces a progressive peripheral compression that determines the retention of the bar in the core, and the interlocking of the various elements concurrent in the knot.
