NEW PIPING, PANEL MEMBER, AND RENEWAL METHOD FOR EXISTING PIPING
To install new piping having a sufficient structural strength inside of existing piping without using a vertical shaft.SOLUTION: The present invention relates to a hinge structure 20, in new piping comprising multiple panels 10 which are disposed in a circumferential direction of existing piping, for connecting the panels 10 which are disposed adjacently to each other in the circumferential direction, with each other. The hinge structure comprises: a first hinge cylinder 21 provided in a first end 11 in a circumferential direction of a first panel 10 between the panels 10 which are disposed adjacently to each other, and extending in an axial direction of the existing piping; a second hinge cylinder 22 provided in a second end 12 in a circumferential direction of a second panel 10 between the panels 10 which are disposed adjacently to each other, extending in the axial direction and disposed at a position which is different from that of the first hinge cylinder 21 in the axial direction; and a core rod 23 which extends in the axial direction and is inserted into the first hinge cylinders 21 and 22.SELECTED DRAWING: Figure 5
【課題】立坑を用いることなく、十分な構造強度を備える新設配管を既設配管の内部に設置する。【解決手段】既設配管の内部に、既設配管の周方向に配置された複数のパネル１０を備える新設配管において、周方向に隣り合って配置されるパネル１０同士を接続するヒンジ構造２０であって、隣り合って配置されるパネル１０同士のうちの第１のパネル１０の周方向における第１端１１に設けられ、既設配管の軸方向に延びる第１のヒンジ筒２１と、隣り合って配置されるパネル１０同士のうちの第２のパネル１０の周方向における第２端１２に設けられ、軸方向に延び、第１のヒンジ筒２１と軸方向で異なる位置に配置される第２のヒンジ筒２２と、軸方向に延び、第１および第２のヒンジ筒２１、２２に挿通される芯棒２３と、を備えることを特徴とする。【選択図】図５
