<P>PROBLEM TO BE SOLVED: To provide a new electric fusion joint, a joining method using the same, and a joining structure between the electric fusion joint and a synthetic resin tube, and to provide an electric fusion joint that can be easily applied in a narrow space such as the inside of a pipe shaft of a collective housing and a narrow excavation channel, a joining method using the same, and a joining structure between the electric fusion joint and the synthetic resin tube. <P>SOLUTION: An electric fusion joint 10 is used for fusion joining between synthetic resin tubes 12 together, and includes a joint body 14 and a temporary fixing part 16. A socket 18 at both end openings of the joint body 14 receives a tube end of each of the synthetic resin tubes 12. On an outside surface of the joint body 14, a power source connection terminal 22 is formed to protrude itself. The temporary fixing part 16 is arranged outside the axial direction of the joint body 14, fixed onto the outside surface of each of the synthetic resin tubes 12, and is hooked on the power source connection terminal 22. According to the present invention, synthetic resin tubes are fusion-joined together even in a narrow space by a simple operation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
