挟着される継手部材へのパイプ仮止め装置。 A block-shaped joint member having a fluid flow passage into which the end of the pipe can be inserted and a bolt through hole, which is a device for temporarily fixing a pipe having an annular projection extending over the entire circumference on the outer peripheral surface of the end to the joint member. a plate-shaped pipe mounting member, which has a notch for inserting a pipe that matches the opening of the fluid flow passage, and which attaches the pipe to the coupling member with the end of the pipe inserted into the fluid flow passage; A bolt that is fixed and passes through the bolt through hole, and a temporary fastener that is fitted over the shaft of the bolt and press-fitted between the circumferential surface of the bolt and the circumferential surface of the bolt through hole to prevent the bolt from falling off. The pipe is inserted into the pipe fitting notch so that the annular protrusion is on the side of the pipe mounting member facing the coupling member, and the annular protrusion is inserted into the coupling member and the bolt of the coupling member. A device for temporarily fixing a pipe to a joint member which is sandwiched between a pipe mounting member which is temporarily fixed by a bolt passed through a hole so as not to fall out.
