Reticular structure with nodes, rods and panels

A reticular structure (1 ) comprises rods (10) that are connected at their own ends by nodes (20) and form polygonal meshes (2) to be covered by respective polygonal panels (50). Each node (20) comprises a body (21 ) whose peripheral region (22) has, in a same half-space (4), through holes (23) for receiving the end portions of the rods (10) at mutual inclination angles (λ,λ*). The body defines a central manoeuvre space (3) in which lock elements (12) for the rods are arranged. In an aspect of the invention, in the opposite side of the half-space (4) a stiff bridge element (31 ) extends between portions (24) proximate to non-adjacent, e.g. opposite through holes (23), restoring the node continuity so that forces can be exchanged between the corresponding rods, while maintaining a manoeuvre space (3) accessible for mounting operations. Advantageously, support elements (40) of the panels (50) are provided, each support element having a connection portion (41 ) on the peripheral region (22) between two adjacent through holes (23) and, at a predetermined distance (L), a support portion (42) for receiving a vertex (51 ) of a panel. This way, panels (50) are spaced from the rods (10), the panels can be arranged adjacent to each other and can be sealed at their edges, which makes it easier to obtain a simplifying the waterproof structure. In another aspect, the support elements (40) are slidably arranged with respect to the peripheral region (22) along bisectors (b) of the inclination angles (λ) of adjacent holes (23) and the connection portion (41 ) of each support element (40) in configured to abut against the vertex (51 ) of a respective panel (50). Lock means (43) are provided to lock the panel with respect to the peripheral region (22), in order to pre-compress the panels (50).
