To provide a sleeper fixing structure that can be easily and efficiently constructed not only in a normal place but also in a narrow place, can effectively prevent the position of a hook part from being displaced in the circumferential direction, and can be implemented at low cost.SOLUTION: The sleeper fixing structure comprises: a square cylindrical sleeve part 11 attached to a square hole 3a of a sleeper 3 so as to be relatively non-rotatable; an intermediate member 10 having a mounting part 12 projecting laterally from the sleeve part 11; a square shaft part 21 having a square cross section configured to be internally rotatable in the square hole 3a and internally fitted in the sleeve part 11 so as to be relatively non-rotatable; a screw part 22 connected to the upper end of the square shaft part 21; a square hook bolt 20 having a hook part 23 connected to the lower end of the square shaft part 21; and a nut member 30 screwed into the screw part 22 to sandwich a flange portion 2a and the sleeper 3 between the mounting part 12 and the hook part 23.SELECTED DRAWING: Figure 1
【課題】通常箇所は云うまでもなく、狭隘箇所に対しても容易且つ効率的に施工でき、しかも周方向に対するフック部の位置ズレを効果的に防止でき且つ安価に実施可能な枕木固定構造を提供する。【解決手段】枕木３の角孔３ａに相対回転不能に装着される角筒状のスリーブ部１１と、スリーブ部１１から側方へ突出する載置部１２とを有する中間部材１０と、角孔３ａに相対回転可能に内嵌し得る寸法に構成されて、スリーブ部１１に相対回転不能に内嵌される横断面角形の角軸部２１と、角軸部２１の上端部に連設されたネジ部２２と、角軸部２１の下端部に連設されたフック部２３とを有する角フックボルト２０と、ネジ部２２に螺合されて、載置部１２とフック部２３間に、フランジ部２ａと枕木３とを挟持させるナット部材３０とを備えた。【選択図】図１
