Claims

[Claims for Utility Model Registration] A pipe body, a branch connection pipe joint for branching and connecting a branch pipe to the peripheral wall of the pipe body, and a connection structure between the branch pipe joint and the branch pipe, comprising: The joint includes a flexible inner tube that has a locking portion that can be locked in a branch hole drilled in the tube body, and an annular groove that allows a seal member to fit tightly into the inner circumferential edge of the branch hole. an insertion portion into which an inner tube can be loosely inserted; an outer tube having a saddle portion curved approximately along the outer circumference of the tube body at the proximal end of the insertion portion; and an outer tube formed on the outer circumference of the inner tube. The inner tube protrudes outward and is locked to the outer peripheral edge of a branch hole formed in an appropriate position on the peripheral wall of the tube body, and the inner tube is locked in an annular groove of the inner tube. With the sealing member inserted, the sealing member is brought into contact with the inner circumferential edge of the branch hole, and the insertion portion of the outer tube is loosely inserted into the outer circumference of the inner tube, and the outer circumferential edge of the branch hole is inserted. The saddle portion of the outer tube is brought into contact with the inner tube, and the end of the branch tube is inserted into the inner peripheral portion of the inner tube. By being screwed together, the saddle portion of the outer tube is brought into pressure contact with the tube body, and each sealing member is compressed, so that the branch connecting pipe joint is brought into close contact with the branch hole and the branch pipe. Connection structure of branch connection pipe joint.
