Joint structure of the line for the departure prevention guard

摘要

PROBLEM TO BE SOLVED: To provide a joint structure of a deviation prevention guard for a rail track, capable of easily coping with expansion/contraction of the deviation prevention guard accompanying temperature-dependent expansion/contraction or the like of a bridge girder, and capable of surely preventing irregularity from occurring at a connection part between guard materials in the deviation prevention guard when a train is derailed.;SOLUTION: A joint structure of a deviation prevention guard for a rail track comprised of a pair of guard materials 7 and at least one stringer 8 for the guard materials fixed between the pair of guard materials 7 includes: a pair of joint plates 11 arranged astride the inner faces of connection ends of the pair of guard materials 7; and at least one stringer 12 for the joint plates, fixed between the pair of joint plates 11. An end on the upstream side in a train travel direction of each of the pair of joint plates 11 and the guard material 7A on the upstream side in the rain travel direction are not fixed together, while an end on the downstream side in a train travel direction of each of the pair of joint plates 11 and the guard material 7B on the downstream side in the train travel direction are fixed together.;COPYRIGHT: (C)2014,JPO&INPIT
