Resumen

The joining system for mobile lattice structures comprising a core (1) covered by an outer shell (2), with spherical shape achieved by joining two threaded spherical caps, provided with radial holes (3) and a set of rods (4) provided at their ends with threaded elements, for coupling to the knots through the connecting pieces (5), which are formed by a cylindrical part (6) of diameter and threaded equivalent to the interior of the bars (4) , by a conical part (7) that facilitates the penetration of the connection sleeve (5) into the radial holes (3) and a spherical section in the form of a cap (8) that enables the rotation of the bars (4) with respect to the core (1) thanks to a clearance (9).
