TEMPORARY FASTENING MEMBER, FASTENING METHOD, AND ALIGNMENT JIG PROVIDED IN TEMPORARY FASTENING MEMBER
To provide a fastening member, a fastening method using the fastening member, and an alignment jig provided in the fastening member, capable of aligning the insertion holes of objects to be fastened and improving workability in the fastening work of a plurality of members to be fastened in the temporary fixing work performed prior to the final fastening work.SOLUTION: A temporary fixing bolt is inserted through a screw hole formed in a column plate and a through hole B2 formed in the end plate to temporarily fix the column plate and the end plate. The temporary fixing bolt includes a fastening bolt having a head portion and a shaft portion, and an alignment jig 20 that is screwed into the fastening bolt to align the positions of the screw hole and the through hole. The alignment jig 20 has a thin portion 25 formed so as to be deformed inwardly at a portion of its outer peripheral surface 24 in the circumferential direction.SELECTED DRAWING: Figure 9A
【課題】本締結作業に先立って行われる仮固定作業において、被締結体の挿通孔の位置合わせをすることができるとともに、複数の被締結部材の締結作業における作業性の向上を図ることが可能な締結部材、該締結部材を用いた締結方法、及び前記締結部材が備える位置合わせ治具を提供する。【解決手段】仮固定ボルトは、柱プレートに形成されたねじ孔と、エンドプレートに形成された貫通孔Ｂ２に挿通されて、柱プレート及びエンドプレートを仮固定する。仮固定ボルトは、頭部と軸部とを有する締結ボルトと、締結ボルトに螺合されて、ねじ孔と貫通孔の孔芯の位置を合わせるための位置合わせ治具２０と、を備え、位置合わせ治具２０は、その外周面２４上の円周方向の一部において内側に変形するように形成された薄肉部２５を有する。【選択図】図９Ａ
