<p>PURPOSE:To easily perform connecting work by forming a bending plate made of synthetic resin having mobility, and integrally providing a roll-in part which can roll in a main pipe along its circumferential direction barrel wall, in a branch pipe joint provided with the bending plate brought into surface contact partly with the main pipe barrel wall in a socket of a branch pipe. CONSTITUTION:In a joint structure practicable in sewerage or the like by comprising a main pipe 21 having an opening, branch pipe joint 10 and a binding means, in the case of mounting a branch pipe joint 11 on the main pipe 21, first a bond M is raised up in a connecting surface of a joint main unit 12. Next, an opening 20 of the main pipe 21 corresponds to an opening 13 of the branch pipe joint 11, and by fitting the branch pipe joint 11 to the main pipe 21 so as to press the roll in part 11 spread, the branch pipe joint 11 is tightened by the roll-in part 11. Thereafter, a lever 15 is placed in a condition opened outward, and after a ring 16a, provided in an end part of a band-shaped belt 16, is hooked to a stop part 12b, by closing the lever 15 in a reverse direction, the band-shaped belt 16 is drawn near, to fix the branch pipe joint 10 fastened to the main pipe 21.</p> |
