To provide a flange reinforcement jig which reinforces protruding parts, protruding in a radial outward direction, of both cylindrical members, enables reinforcement of a valve case split part, and achieves high work efficiency.SOLUTION: A flange reinforcement jig includes: a first sandwiching member 10A; a first fastening mechanism Ka which fastens the first sandwiching member 10A; a second sandwiching member 10B; a second fastening mechanism Kb which fastens the second sandwiching member 10B; and coupling mechanisms R, each of which applies a force acting in an approaching direction in which the first sandwiching member 10A and the second sandwiching member 10B are moved closer to each other. The coupling mechanism R has a coupling bolt Ra. The coupling bolt Ra is also used in the first fastening mechanism Ka and the second fastening mechanism Kb.SELECTED DRAWING: Figure 10 【課題】両筒状部材の径外方向に突出した両突出部どうしを補強すると共に弁ケース分割部の補強も可能な作業効率の高いフランジ補強治具を提供する。【解決手段】第一挟持部材１０Ａと、第一挟持部材１０Ａを締結する第一締結機構Ｋａと、第二挟持部材１０Ｂと、第二挟持部材１０Ｂを締結する第二締結機構Ｋｂと、第一挟持部材１０Ａと第二挟持部材１０Ｂとを近接させる近接方向の力を印加する連結機構Ｒと、を備え、連結機構Ｒは連結ボルトＲａを有しており、連結ボルトＲａは第一締結機構Ｋａおよび第二締結機構Ｋｂと兼用されている。【選択図】図１０
