<p>PURPOSE:To provide connecting structure enabling sure connection between an electro-fused joint and a metal pipe without generating dispersion in construction. CONSTITUTION:In the connecting structure between a metal pipe 2 and an electro-fused joint 1, a pipe body 3 can be inserted into the electro-fused joint 1 provided with a connecting part 11 with coils 12, heated by current application, embedded therein. The end part outer peripheral surface of the metal pipe 2 is formed into irregular shape to form an insert part 21 with adhesive resin 22 deposited thereto. With current application to the coils 12 in the state of the insert part 21 of the metal pipe 2 being inserted into the connecting part 11 of the electro-fused joint 1, the resin on the inner peripheral surface of the connecting part 11 of the electro-fused joint 1 and the adhesive resin 22 on the outer peripheral surface of the insert part 21 of the metal pipe 2 are fused integrally.</p> |
