摘要： PROBLEM TO BE SOLVED: To prevent a rail from shifting to the direction crossing at right angles, by providing shoulders constituted of a buried part embedded in a sleeper, a pressure-receiving face touching the edge of the bottom of the rail, and a fixing part for a fixing bolt. SOLUTION: A rail R is put on a track pad 70. Spring receive bases 50 are put on the fitting parts 24b of the shoulders 20 in which the buried part 21 is embedded in advance in a sleeper T and the head 61 of a fixing bolt 60 is fitted to the fitting part 23 of the shoulder 20. The bolt 60 is inserted in the bolt hole 33 of a spring clip 30 and an insulation gauge plate 40 is interposed between the rail R and the spring clip 30 and the shoulder 20 and fastened with nuts to assemble a rail fastening device 10 with the level-adjusting function. Then, the bolts 60 are loosened and a level-adjusting plate for the rail is put between the pad 70 and the sleeper T to change the spring receive base to a higher one and raise the rail R. In this way, since the pressure-receiving face 22 is vertical both before and after the rail is raised, the displacement of the rail to the direction crossing at right angles can be prevented.

摘要： Device for anchoring a rail to a sleeper (T) of the type comprising an insert (1) anchored in said sleeper, a resilient rail fastener (2), at least one insulating spacer (31, 32) arranged between the insert (1) or the fastener (2) and the rail (R), a sleeper pad (S) supporting the rail base and a member (4, 4') for clamping the fastener (2) onto the insert (1). According to the invention, the clamping member (4, 4') comprises, in particular, a shaft (40, 40') having, in its lower portion, a holding element (41, 41') formed from at least one bearing surface (41a, 41b, 41'a) radially extending beyond the shaft. The insert (1) includes a stationary front face (1a) forming an abutment surface for the lateral forces of the rail and an inner space (10) provided with at least one upper opening (11), wherein the profile and respective dimensions of the opening are determined so as to enable the insertion and translation of the clamping member (4, 4') and fastener (2), and locking of the holding element (41) in said space (10) through a movement of the clamping member in said opening (11).

摘要： PURPOSE:To provide the title fastener for which a wire spring made of wire with a small diameter can be used and by which a fastening load can be stably displayed. CONSTITUTION:A fastener 10 consists of a wire spring 13 for depressing a flange part 12 of a rail 11 and a spring support 14 for fastening the wire spring 13 onto the side of a rail support 15. The wire spring 13 has an end part 25 for fastening, which is inserted into a setting hole horizontally formed on the spring support 14. This wire spring 13 also has a first support part 27 extending from the end part 25 to the side of a spring-bearing surface 21 through a first bent part 29, an intermediate arm part 31 extending from the first support part 27 to the side of the flange part 12 through a second bent part 30, and a second support part 35 extending from this intermediate arm part 31 to the spring-bearing surface 21 through a third bent part 32. The intermediate arm part 31 depresses the flange part 12 from above and the support parts 27, 35 are supported by the spring-bearing surface 21.
