FASTENING TOOL, AND FASTENING METHOD USING FASTENING TOOL
PROBLEM TO BE SOLVED: To join a plurality of joined members together by fastening in a manner of enabling easy and quick fastening work and also obtaining a desired fastening state between the joined members.SOLUTION: The present invention is related to a fastening tool 35 which is used when a shaft body 25 having one end in an axial direction formed with a flange part 26 and the other end formed with a screw part 27 is pressed from the screw part 27 side into penetration holes 22-24 on a common axis 21 formed on a plurality of mutually-abutting joined members 17-19, so that each of the plurality of joined members 17-19 is clamped and fastened by a screw body 28 screwed in the flange part 26 and the screw part 27. The fastening tool 35 includes a guide tool 36 which is removably fitted to the screw part 27, formed in a tapered shape toward the outside in the axial direction of the screw part 27, and guides the shaft body 25 to be pressed into the penetration holes 22-24.SELECTED DRAWING: Figure 1
【課題】複数の被連結材同士を締結により連結するに際し、締結作業が容易かつ迅速にできるようにすると共に、被連結材同士の間に所望の締結状態が得られるようにする。【解決手段】本発明は、互いに当接する複数の被連結材１７〜１９に形成された同一軸心２１上の貫通孔２２〜２４に対し、軸方向の一端部に鍔部２６が形成され他端部にねじ部２７が形成された軸体２５をねじ部２７側から圧入し、鍔部２６とねじ部２７に螺合される螺合体２８とにより各被連結材１７〜１９を挟み付けて締結するに際し用いられる締結用治具３５に関するものである。締結用治具３５は、ねじ部２７に嵌脱可能に嵌合され、ねじ部２７の軸方向の外方に向かってのテーパ形状とされて貫通孔２２〜２４への軸体２５の圧入を誘導する誘導治具３６を備える。【選択図】図１
