In the case of a load-bearing framework of a reflector (7) which is connected to a foundation - preferably so that it can rotate about a vertical axis (13) - and is constructed as a lattice which is composed of triangles and has a triangular horizontal base frame (1) one of whose rods runs parallel to a horizontal axis (8) about which the reflector (7) is arranged such that it can pivot on the upper end of the load-bearing framework, a simple and cheap design is achieved in that the load-bearing framework has at its upper end a triangular frame (4) which is in the opposite direction to the base frame (1) and whose corners (a, b, c) are in each case connected to the corners (A, B, C) of the base frame (1). <IMAGE>
