Supporting prefabricated component for e.g. building, has integrated solar collector unit arranged between pair of support longitudinal units, and transverse unit for statically connecting two support longitudinal units with each other

摘要

The component (1) has an integrated solar collector unit (4) arranged between a pair of support longitudinal units (2). A transverse unit (3) is provided for statically connecting two support longitudinal units with each other. An external side (7) of the component is turned towards atmosphere, where a space between two support longitudinal units is closed in a weather-proof manner in the external side by using a cover (8), which is permeable for a partial spectrum of solar radiations.
