摘要： Provided is a flange coupling part reinforcing jig capable of reinforcing a conduit including two flange parts into an earthquake-resistant conduit having a predetermined earthquake-resistance performance and yet capable of easily and economically preventing separation or displacement between the two flange parts. A flange coupling part reinforcing jig P includes a pair of clamping members 5, 6 having pressing parts 5C, 6B capable of coming into contact respectively with outer faces 1a, 1a of two flange parts 1A, 1B which are bolt-connected and a fastening means 7 for fixedly fastening the two clamping members 5, 6 by drawing them to each other in a flange coupling direction, with the pressing parts 5C, 6B of the clamping members 5, 6 being placed in abutment with the outer faces 1a, 1a of the flange parts 1A, 1B. At portions of the two clamping members 5, 6 opposed to each other in the flange coupling direction, there are formed an inner fitting part 5A and an outer fitting part 6A which are fitted to each other in the flange coupling direction at positions of the two flange parts 1A, 1B more radially outward than outer circumferential faces 1c, 1c of the two flange parts 1A, 1B.
