RAIL INTERVAL ADJUSTMENT STRUCTURE
To provide a rail interval adjustment structure capable of appropriately supporting the bending moment acting on a guard rail between a first interval adjusting member and a second interval adjusting member, thereby making a fixing member appropriate.SOLUTION: A first interval adjusting member and a second interval adjusting member are provided whose thicknesses in a gauge direction change in a rail longitudinal direction between a stock rail and a guard rail; a contact surface between the first interval adjusting member and the second interval adjusting member has an engaging surface having a recess and a protrusion; a fixing member is provided that fixes the stock rail, the first interval adjusting member, the second interval adjusting member and the guard rail while adjusting a predetermined interval between the stock rail and the guard rail by changing the engaging position of the engaging surface between the first interval adjusting member and the second interval adjusting member in the rail longitudinal direction; and a contact portion between the first interval adjusting member and the second interval adjusting member has a moment supporting portion for supporting the rotational moment of lateral force to the outside of the gauge acting on the guard rail.SELECTED DRAWING: Figure 3
【課題】 ガードレールに作用する曲げモーメントを第一間隔調整部材と第二間隔調整部材との間で適切に支持して固定部材を適切にできるレール間隔調整構造を提供する。【解決手段】 基本レールとガードレールとの間に軌間方向の厚みがレール長手方向に変化する第一間隔調整部材と第二間隔調整部材とを備え、第一間隔調整部材と第二間隔調整部材との接触面は、凹部と凸部とを有する係合面を有し、第一間隔調整部材と第二間隔調整部材との係合面の係合位置をレール長手方向に変更することで基本レールとガードレールとの所定間隔を調整した状態で、基本レールと第一間隔調整部材と第二間隔調整部材とガードレールとを固定する固定部材を備え、第一間隔調整部材と第二間隔調整部材との接触部分は、ガードレールに作用する軌間外方への横力の回転モーメントを支持するモーメント支持部を有している。【選択図】 図３
