Prestressed solar collector module

Abstract

The invention relates to a prestressed solar collector module forming a support structure for solar collectors, of the type formed by a lattice bar structure including a central beam (1) essentially characterized in that: the central beam or torque box (1) takes the form of a multi-face polyhedron or cylinder, that is divided into sections (3) each section (3) being formed by multiple bent or curved plates (4), a surrounding triangular lattice structure (16) is provided to support the parabolic reflector (17) which structure is formed with L-shaped elements, all of the connections being formed with rivets, and all of the structure is prestressed using a series of tension rods (13, 14, 15) which optimise the flexural behaviour of the structure and which include end anchoring points and intermediate through-points allowing the necessary curvature to be obtained and the tension to be maintained.
