Space frame based on cylindrical steel jointing elements + has bolted bar assemblies with flanges and perforations

摘要

Spatial structure, from two types of bars (1-1 "''), the first with flat and perforated flanges (2) and the second with frusto-conical heads (5) provided with an axial and threaded hole, these are fixed between yes with the collaboration of knots materialized in a core (7), consisting of a short steel cylinder, which at its ends receives several plates (9) and (10) jointly, one with radial extensions (11), coplanar, for fixing of the flanges (2), and another with extensions (11 "'') obtusely angled inward, to receive the head of the conical heads (5) of the other type of bars (1" ''), so that Through the bars with flanges (2) flat reticular structures are obtained that are related to each other through oblique braces defined by the bars finished in frusto-conical heads (5).
