System for mounting solar modules at roof construction of flat roof, has connection for connecting module rail with support element such that support element is movably connected with module rail along longitudinal direction of module rail

摘要

The system (4) has a support element (44) for transferring compressive forces to a roof construction, where the forces are exerted over a module rail (40) in a direction of upper side of the roof construction. The system comprises a connection for connecting the module rail with the support element such that the support element is movably connected with the module rail along longitudinal direction (x) of the module rail. The connection comprises flanges (42, 43) and two C-profiles. The support element is displaceably arranged between a fastening screw (2) and a point holder.
