RAIL FASTENING STRUCTURE

摘要

PURPOSE: A rail fastening structure is provided to easily separate lower members of a rail without bolts separation, and to improve the fastening strength of the bolts. CONSTITUTION: A rail fastening structure comprises a height adjustment pad(200), pressure dispersion units(300), pressure units(400), and fasteners(500). The height adjustment pad is formed between a rail and a sleeper. The pressure dispersion units are formed between the rail and the height adjustment pad. Cutout parts(310a,322a) are formed in the pressure dispersion units. A first elastic member(440) which elastically supports the rail toward the sleeper is formed in the pressure units. The fastener is composed of a bolt(510), more than one washer(520), and a wedge washer(530). The bolt is arranged in a horizontal direction of the rail. The washers are fitted to the bolt. A saw-teeth(S) is formed in the bottom of the wedge washer.
