Abstract:
To provide a construction jig which enables a main pipe to be perforated smoothly even if cutting resistance received by a cutter is large when the main pipe is perforated, and to provide a construction method of a branch pipe.SOLUTION: A construction jig 1 forms a cold/hot water pipeline and is used to connect a branch pipe 16 to a main pipe 15 in which a liquid flows. The construction jig 1 includes: a first member 10 having an insertion pipe part 12 into which the branch pipe 16 is inserted; and a second member 20 which sandwiches the main pipe 15 with the first member 10 and fixes the first member 10 to the main pipe 15. The second member 20 has rigidity equivalent to the first member 10 in a pipe axis direction O2 of the insertion pipe part 12 in a state where the first member 10 is fixed to the main pipe 15.SELECTED DRAWING: Figure 2
