Claims

[Claims for Utility Model Registration] A ribbed tube having a large number of annular ribs on its outer circumferential surface;
A connection structure with a branch connection pipe joint for connecting a branch pipe to the peripheral wall of the ribbed pipe, wherein the branch connection pipe joint has a saddle portion that is curved approximately along the outer circumference of the rib of the ribbed pipe. and a branch pipe connection part protruding from the outer surface of the saddle part, and a branch hole is formed at an appropriate position on the peripheral wall of the ribbed pipe,
A bonding agent is filled between the ribs in a portion surrounding the branch hole and covered by the saddle portion of the branch connection pipe joint, with a spacer interposed therein to reduce the space between the ribs, and A connection structure for a branch connection pipe joint for a ribbed pipe, characterized in that a joint surface of the saddle portion is pressed against the outer periphery of a rib of the ribbed pipe, and the branch connection pipe joint is connected and fixed to the ribbed pipe.
