The heating wires 2 are connected to the pins 31 of the connector 3, and the heating wires 2 are buried at predetermined intervals on the inner peripheral surface of the branch port 13, similarly to the above embodiment. Also in the case of the branch joint A2 of this embodiment, a plurality of branch joints A2 can be sequentially connected in the same manner as in the previous embodiment to form a branch piping header. The branch pipe C can be fusion bonded.

の際に枝管の取り出しが簡単、かつ確実に行なえる。As described in detail above, the present invention forms a branch piping header by using a plurality of branch joints, and the branch joint has a receiving port at one end and the receiving port at the other end. Since the spigot to be inserted into the mouth is provided, it is possible to form a header having a desired number of branch ports that require the branch pipe to be taken out simply by connecting a plurality of branch joints sequentially. Further, the connection direction of each branch port can be appropriately adjusted only by rotating the branch joint about the axis. When a heating wire buried in the inner peripheral surface of the receiving port or the outer peripheral surface of the spigot of each branch joint is energized to generate heat, a plurality of branch joints are integrally fused and joined, so that piping work at the site can be performed. In this case, the branch pipe can be easily and reliably taken out.
