    • 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.
    • 要解决的问题:为了提供一种用于轨道轨道的偏差防护装置的接合结构,能够容易地应对与桥梁的温度依赖性的扩张/收缩等相应的防偏移防护装置的伸缩,并且能够 可靠地防止在列车脱轨时防偏转防护装置中的防护材料之间的连接部分发生不规则。解决方案:用于轨道的防偏转防护装置的接合结构包括一对防护材料7和至少一个 固定在一对防护材料7之间的防护材料的纵梁8包括:一对跨接在一对防护材料7的连接端的内表面上的连接板11; 以及至少一个用于接合板的纵梁12,固定在一对接头板11之间。一对接头板11的列车行进方向上游侧的端部和上游侧的保护件7A 雨行驶方向不固定在一起,而在列车行进方向的下游侧的一对接合板11和保护材料7B的列车行进方向的下游侧的端部固定在一起。
