Reticular spatial structure
First Claim
1. Reticular spatial structure comprising;
- perimetral nodes,a plurality of perimetral rod-like elements having ends, said ends being associated with said perimetral nodes,connecting nodes defining a geometrical center and each comprising a lower plate, an upper plate, and a hollow body having an inner surface and an outer surface,a plurality of variable-length rod-like elements having ends and axes, said ends being hingeable to said connecting nodes to form a framework, at least part of said variablelength rod-like elements being rotatable both about said axes and with respect to said geometrical center of said connecting nodes for causing extension of said variablelength elements to a final selected extension length during raising of said framework to form a reticular spatial structure having a dome-like shape, said structure further comprising;
node rod fixing bolts adapted for fixing said rod-like elements to said nodeslocking means adapted to prevent return of said rod-like elements to a length which is different from said final selected extension length,a rocker suspension pivot connected to each said hollow body, anda covering membrane held by said lower plate and said upper plate of each of said connecting nodes and coupled to said rocker suspension pivot, wherein said inner surface and said outer surface of said hollow body are shaped as equatorial segments of concentric spheres, and wherein said hollow body has a wall inscribed by said two concentric spheres and provided with a plurality of openings, said openings being arranged radially for allowing insertion of said node-rod fixing bolts and for achieving structural continuity of said structure after pneumatic raising thereof.

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.
