摘要:
Screw dowel for concreting into a railway sleeper or ballastless track and frictionally connecting to a sleeper screw, containing a threaded portion (14) with external thread flights (18) arranged on the outside of the screw dowel (10) and with internal thread flights (19) arranged on the inside of the screw dowel; and an upper subportion (16) without external thread that is situated close to the dowel opening (26) in the installed state; the screw dowel containing two constituent parts made of different materials, namely a basic body made of plastic and a cylindrical ring (20) made of a steel material and mounted with a form fit and/or force fit.
摘要:
The invention relates to a system for fastening a rail (S), comprising a sleeper (1) which has a supporting face (3) intended to support the flange (Sf) of the rail (S), the supporting face (3) merging, at its sides which extend parallel to the longitudinal extent (L) of the rail (S) to be fastened thereto, into respective levelling faces (7, 8) which are situated at a higher level than the supporting face (3), an angled mounting plate (20, 21) which has, in each case, a central portion (22), on the underside (23) of which is formed a support surface (24) by which the angled mounting plate (20, 21) can be placed down on the respective levelling face (7, 8) assigned to it of the sleeper (1), and a supporting portion (25) which is formed onto the central portion (22) and points downwards from the underside (23) of the latter and which, when the system is fully fitted, bridges the clear space between the flange (Sf) of the rail (S) and the levelling face (7, 8), a resilient member (100, 101) which can be placed down on the angled plate (20, 21) and which has, in each case, two holding arms (105, 106) by which, when the system is fully fitted, the resilient member (100, 101) exerts a holding force (H) on the rail (S), and a clamping member (P) which, when the system is fully fitted, exerts a clamping force (F) on the resilient member (100, 101). Such a system achieves an improved ability to be permanently loaded and exhibits a prolonged lifetime at reduced production costs, in that according to the invention when the system is fully fitted, the axis (W) along which the clamping force (F) exerted by the clamping member (P) acts passes through the levelling face (7,8).

Disclosed is a guide plate for the lateral guidance of a rail and to a rail fastening system with such a guide plate. The guide plate has a contact area, on which the guide plate stands in the completely assembled state, and a support portion, which is associated with the counter bearing, with a support face, with which the guide plate 1 is supported, in the completely assembled state, on a counter bearing.

A system for fastening a rail includes a sleeper having a supporting face supporting the flange of the rail and merging at its sides into respective levelling faces situated at a higher level than the supporting face, an angled mounting plate having a central portion on the underside of which is formed a support surface by which the angled mounting plate can be placed down on the respective levelling face assigned thereto, a supporting portion formed onto the central portion and pointing downwards from the underside of the latter and which can bridge a clear space between the flange of the rail and the levelling face, a resilient member which can be placed down on the angled plate and has two holding arms by which the resilient member can exert a holding force on the rail, and a clamping member which can exert a clamping force on the resilient member.
