FASTENING OF A SUPPORT RAIL FOR A PV MODULE TO A TRAPEZOIDAL SHEET

摘要

A fastening of a support rail for a photovoltaic module to a trapezoidal rib of a trapezoidal sheet. The support rail comprises an undercut groove with a groove opening. The trapezoidal rib comprises an upper side and a slanted side. The support rail is positioned transversely to the trapezoidal rib. The fastening includes at least one retaining element comprising a fastening section fastened to the slanted side of the trapezoidal rib, and an engaging extension non-detachably arranged thereon. The engaging extension engages the undercut groove in an engaging position. The engaging extension is insertable through the groove opening into the undercut groove of the support rail in a loose position that is rotated relative to the engaging position. The support rail is held down against the upper side of the trapezoidal rib by the engaging extension. The at least one retaining element is arranged either left or right of the trapezoidal rib.
