<p><P>PROBLEM TO BE SOLVED: To materializes compaction in a pipe axial direction of a flexible connection structure constituted between fixing piping and connecting pipe, reduction in manufacturing cost and improvement in construction efficiency. <P>SOLUTION: Inside a socket pipe 5 which can be fixed and connected to an end of fixing piping 1 fixed on a structure A, ground or the like, a thermoplastic resin made partially spherical ring 6 equipped with the partially spherical outer peripheral surface 6a freely slidable along the partially spherical inner peripheral surface 5a formed in the socket pipe is mounted from the direction of the pipe axial center X in a coming-off prevention state. A connecting pipe 2 made of thermoplastic resin is connected to be internally fitted in a through hole 6A of the partially spherical ring 6 from the direction of the pipe axial center X. The partially spherical ring 6 and the connecting pipe 2 are integrally formed by thermal fusion bonding. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
