PROBLEM TO BE SOLVED: To provide a crosstie fixing structure in which a fixing part of a crosstie is hard to wear.SOLUTION: A fixing structure of a crosstie 1 has a hook bolt 4 which is fixed to a bridge girder 2 and protrudes upward of the bridge girder 2. The hook bolt 4 penetrates through an open hole 10 of the cross tie 1 disposed on the bridge girder 2. A screw part 4b is formed at a part of the hook bolt 4 protruding from the open hole 10 of the crosstie 1. A nut 9 is fit to the hook bolt 4 through a washer 8. The crosstie 1 is fixed to the bridge girder 2 by screwing the nut 9 with the screw part 4b of the hook bolt 4. An elastic member 7 is disposed between the washer 8 and the crosstie 1 and the elastic member 7 is adhered to the crosstie 1.SELECTED DRAWING: Figure 3
【課題】まくら木の固定部分が摩耗しにくいまくら木の固定構造を提供することである。【解決手段】橋桁２に固定され、橋桁２の上方に突出するフックボルト４を有し、フックボルト４は、橋桁２の上に配置されたまくら木１の貫通孔１０を貫通しており、フックボルト４におけるまくら木１の貫通孔１０から突出した部分にはねじ部４ｂが設けられており、フックボルト４に座金８を介してナット９を装着し、フックボルト４のねじ部４ｂにナット９を螺合することによって、橋桁２にまくら木１を固定するまくら木１の固定構造であり、座金８とまくら木１の間に弾性部材７を配置し、弾性部材７とまくら木１を接着した。【選択図】図３
