Carrier structure for carrying photovoltaic panel that is fixed on standard steel trough-type roof, has connection unit for allowing translation of carrier rails relative to support rails along longitudinal axis of carrier rails

摘要

The structure (1) has carrier rails (10) fixed at top parts of ribs (3A) and comprising an upper wall and two wings that are downwardly directed towards the structure. Short support rails (20) comprise an upper wall and two downwardly directed wings. A connection unit is connected with an inner face of the wings of the carrier rails and allows translation of the carrier rails relative to the support rails along a longitudinal axis of the carrier rails. A tightening part comprises a hook that is articulated on a base. The base comprises multiple clevis pins.
