Claims

[Claims for Utility Model Registration] A connection structure between a pipe body and a branch connection pipe joint for branching and connecting a branch pipe to the peripheral wall of the pipe body, wherein the branch connection pipe joint is connected to a pipe body by penetrating the pipe body. A flexible inner tube formed with a locking part that can be locked to a branch hole, an annular groove that brings a sealing member into close contact with the inner peripheral edge of the branch hole, and an insertion part into which the inner tube can be loosely inserted. and an outer tube having a saddle portion curved approximately along the tube outer circumference of the tube body formed at the proximal end of the insertion portion, and an outer tube screwed onto the inner circumference of the inner tube. The inner tube protrudes outward and is locked to the outer periphery of a branch hole formed in an appropriate position on the peripheral wall of the tube body, and a sealing member is interposed in an annular groove of the inner tube. , the sealing member is brought into contact with the inner peripheral edge of the branch hole, the insertion part of the outer cannulation tube is loosely inserted into the outer peripheral part of the inner tube, and the saddle part of the outer cannulation tube is brought into contact with the outer peripheral edge of the branch hole. The saddle portion of the outer tube is brought into pressure contact with the tube body by screwing the outer tube into the inner circumferential portion of the inner tube through the sealing member and the protruding end of the inner tube. A connection structure for a branch connection pipe joint, characterized in that each sealing member is compressed so that the branch connection pipe joint is brought into close contact with a branch hole.
