ABSTRACT:
A reticular spatial structure comprising a plurality of perimetral rod-like elements which are associable, at their ends, with perimetral nodes; a plurality of variable-length rod-like elements hinged to connecting nodes having a spherical contact surface adapted to allow the rotation of at least part of the variable-length rod-like elements both about the axis of said elements and with respect to the geometrical center of the various nodes, for the extension of the variable-length elements during the raising of the framework which is preassembled on a base plane. A connecting node comprises a lower plate and an upper plate securing a covering membrane, which can be fixed to a rocker suspension pivot connected to a hollow body having both the outer surface and the inner surface in the shape of equatorial segments of concentric spheres. The hollow body is provided with openings for the insertion of the node-rode fixing bolts.
