摘要

The device (1) has an elongated plate-shaped support arm (3) comprising triangular shaped recesses (9), which are spaced from each other and include a beveled edge area and form a framework. The edge area forms a rib protruding from a main plane of the support arm. The support arm is provided with a lower bent section and an upper bent section of an upper edge, which forms a support surface for a reflector (110). The support arm is provided with a flange (7) at a front end (5) for fastening at a central support (120) of a parabolic trough receiver (100).
