Arrangement for securing railway rails onto sleepers
摘要:
The invention relates to a rail securing arrangement, which has the following features. It comprises metal plates, each of which lies with its flat lower surface on the sleeper, and on whose upper surface two ribs are formed which extend in the longitudinal direction of the rail, and between which the foot of the sleeper lies on a bearing surface. On both sides of the rail in the region of the respective ribs, each plate has moreover at least one through-hole, with which a respective through-hole in the sleeper is aligned. Corresponding screws are each introduced with their lower ends into the respective through-holes of the plate and engage with a hook-like bend beneath the lower surface of the plate. Each screw is provided at its upper end with a thread onto which a respective nut is screwed. Furthermore, the securing arrangement comprises plate-like securing elements which are each bent to form a double-armed angle member. The first arm of each securing element engages, together with the associated screw in the corresponding through-hole in the plate, whereby the screw is fixed in this through-hole in such manner that the hook-like bend of the screw engages securely beneath the lower surface of the plate. The second arm of each securing element extends perpendicularly away from the rail and lies at least partially on the upper surface of the plate. Finally, clips are provided, which each have a respective screw. Each clip consists of a round-sectioned steel rod and possesses a form which is symmetrical to a vertical plane perpendicular to the rail. Each clip surrounds the associated screw with a central part which lies beneath the nut. A part of the clip facing the rail lies on the rail foot, while an outer part of the clip facing away from the rail presses from above on the upper surface of the plate.
