<p>Support structure for a solar collector consisting of two sets of bars linked by assembly nodes, a concave triangulated lattice (1) around the central node (10) positioned on the sighting axis (xx'), and a stiffening lattice (2) separated from the concave lattice (1) by struts (3, 6), the bars of the two lattices, positioned in a number of planes (P, Q, R) passing through the axis, constituting rigid half-trusses extending radially from a common central strut consisting of a column (3) positioned on the sighting axis (xx') and carrying at its ends the central nodes (10, 20) of the two sets of bars. The set of stiffening bars (2) is positioned on the outer side of the concave lattice (1) together with the central column (3), and the central node to which it is fixed consists of an extended base (20) forming an assembly component, fixed to the end of the central column (3) in a plane perpendicular to the axis and on which are arranged anchor points (21, 22, 23) for at least three pairs of bracing bars (81, 82) which meet two by two in three assembly nodes (A2, A4, A6) of the concave lattice (1) and each forming a triangle whose apex consists of the corresponding node (A2) and whose base consists of the assembly component (20) between the two anchor points (21, 22) separated from one another, to which the corresponding bars (81, 82) are attached.</p> |
