Claims

[Claims for Utility Model Registration] A ribbed tube having a large number of annular ribs on its outer circumferential surface;
This is a connection structure with a branch connection pipe joint for connecting a branch pipe to the peripheral wall of the ribbed pipe, the branch connection pipe joint comprising a branch pipe connection pipe having a socket for receiving an end of the branch pipe, and a ribbed pipe joint. an inner tube having a locking part that can be locked in a branch hole drilled in the pipe; an insertion part into which the branch connecting pipe and the inner tube can be inserted; and curved to approximately follow the rib outer periphery of the ribbed tube. The inner pipe of the branch connection pipe joint is secured to the peripheral edge of a branch hole formed at a proper position on the circumferential wall of the ribbed pipe in a state in which the inner pipe protrudes outward, and the branch A bonding agent is filled between the ribs of the portion covered by the saddle portion of the branch connection pipe joint at the periphery of the hole, and the bonding surface of the saddle portion is brought into contact with the surface of this bonding agent, and the saddle portion is bonded. The inner tube is inserted from the insertion part on the surface side, and the branch pipe connection pipe is inserted from the other direction side of this insertion part, and the saddle part is joined by joining the branch pipe connection pipe and the inner pipe. 1. A connection structure for a branch connection pipe fitting for a ribbed pipe, characterized in that the bonding agent is pressed onto the surface of the joint and compressed and filled between the ribbed pipe and the branch connection pipe fitting.
