FASTENER FOR CORRUGATED SHEETING

摘要

A fastener (11) for securing flexible corrugated sheets (15) to a structural support (17). The fastener (11) comprises a spacer (12) which has a body (13) for insertion through a hole (14) in the corrugated sheeting, and a flange (16) near to the upper end of the body for overlapping the sheeting around the hole. The body has a hole through which a screw (10) passes. The screw secures the spacer to the supporting structure. The corrugated sheeting is held down by the flange of the spacer. The spacer thus controls the force on and compression of the corrugated sheeting.
