PROBLEM TO BE SOLVED: To provide a reinforcement jig which reinforces peripheral areas of connection bolts in all joint parts and prevents separation and misalignment of the joint parts.SOLUTION: A reinforcement jig includes: a first sandwiching member 6 which presses an outer surface 1a of a first protruding part 1A with which a head part 4a of a connection bolt 4 contacts; a second sandwiching member 5 which presses an outer surface 1a of a second protruding part 1B; and a fastening mechanism 7 which fixes the first sandwiching member 6 and the second sandwiching member 5 so that the first sandwiching member 6 and the second sandwiching member 5 are located close to each other in a joint direction of the first protruding part 1A and the second protruding part 1B. The first sandwiching member 6 includes two pressing parts 6B, 6B which press both side areas of the head part 4a which are located along a circumferential direction of a first cylindrical member T on the outer surface 1a of the first protruding part 1A.SELECTED DRAWING: Figure 6 【課題】あらゆる接合部における連結ボルト周りを補強することが可能で、接合部の離間や位置ずれを防止できる補強治具を合理的に構成する。【解決手段】連結ボルト４の頭部４ａが当接する第一突出部１Ａの外側面１ａを押圧する第一挟持部材６と、第二突出部１Ｂの外側面１ａを押圧する第二挟持部材５と、第一挟持部材６と第二挟持部材５とを、第一突出部１Ａおよび第二突出部１Ｂの接合方向に近接させて固定する締結機構７と、を備え、第一挟持部材６は、第一突出部１Ａの外側面１ａにおいて、第一筒状部材Ｔの周方向に沿った頭部４ａの両側の領域を押圧する二つの押圧部６Ｂ，６Ｂを有している。【選択図】図６
