Claims

[Claims for Utility Model Registration] A connection structure between a ribbed pipe having a large number of annular ribs on the outer peripheral surface of the pipe body and a branch connection pipe joint for connecting a branch pipe to the peripheral wall of the ribbed pipe, comprising: A branch hole bored at an appropriate location on the circumferential wall of the ribbed pipe has an outer annular portion that fits into a rib on the outer peripheral edge of the branch hole and comes into close contact with the outer circumferential surface of the tube body; An elastic body consisting of an inner annular part that is in close contact with the inner peripheral edge, and a tapered part that is continuous in the branch hole from the outer annular part to the inner annular part and has a tapered surface on the inner diameter part. On the other hand, the branch connection pipe joint includes a socket part for receiving the end of the branch pipe, a tapered part formed with a tapered surface that closely contacts the tapered surface of the elastic body, and an inner annular part of the elastic body. A branch pipe connecting pipe is provided with a locking part that is locked to the pipe, and an insertion part into which the branch pipe connection pipe can be inserted, and a press-fitting part into which the elastic body is press-fitted is formed on the periphery of the insertion part. , a saddle part that fits into the rib of the ribbed pipe and is curved so as to substantially follow the pipe main body; a locking part of the branch pipe connecting pipe is locked to the inner annular part of the elastic body; A branch connection for a ribbed pipe, characterized in that the tapered part of the branch pipe connecting pipe is pressed into contact with the tapered part of the elastic body, and the outer annular part of the elastic body is press-fitted into a press-fitting part. Connection structure of pipe joints.
