STEEL SLEEPER
To provide a steel sleeper that does not cause ballast outflow during compaction work of a track bed, prevents the multiple tie tamper from interfering with the compaction work, and exhibits an appropriate lateral resistance.SOLUTION: A steel sleeper 100 comprises: an upper face plate 10 to which rails are fastened; a body part having a front plate 13 and a rear plate 14 respectively extending in a hanging shape from a front edge 11 and a rear edge 12 of the upper face plate 10; and a left side face plate and a right side face plate 18 respectively extending in an inclined hanging shape from a left side edge and a right side edge 16 of the upper face plate 10. The distance between the front plate 13 and the rear plate 14 is constant, and an end edge opening of the left side face plate and an end edge opening 19 of the right side face plate 18 are located below a lower edge 13b of the front plate 13 and a lower edge 14b of the rear plate 14.SELECTED DRAWING: Figure 8
【課題】道床の搗き固め作業の際のバラストの流出が発生せず、マルチプルタイタンパーによる搗き固め作業が阻害されることがなく、適度な横抵抗力を発揮する、鉄まくらぎを提供する。【解決手段】鉄まくらぎ１００は、軌条が締結される上面板１０と、上面板１０の前縁部１１並びに後縁部１２からそれぞれ垂下状に延設された前面板１３並びに後面板１４と、を有する本体部と、上面板１０の左側縁部並びに右側縁部１６からそれぞれ傾斜垂下状に延設された左側面板並びに右側面板１８と、を備え、前面板１３と後面板１４との間隔は一定であり、左側面板の端縁開口部並びに右側面板１８の端縁開口部１９が前面板１３の下縁部１３ｂ並びに後面板１４の下縁部１４ｂより下方に位置している。【選択図】図８
