Neck fastening for mechanical line-fastening of insulating material and sealing tracks on flat roofs consists of rail with holes and fastenings formed from screws anchored onto rail bottom and supported with head on rail

摘要

Neck fastening consists of a rail with holes made in the rail bottom and individual fastenings. Fastenings are each formed from a screw (1) which is put in the rail base, supported with its head (3) on the rail and which cuts with its end into the roof bottom or juts into a wall plug anchored into the roof base. From both sides of the hole on the rail narrow positioning edges or noses protrude on which the underside of the screw head lies. When its clamping force is held steady suspended see-saw like between its positioning edges or noses, the rail lies on the underside of the screw head.
