PIPE JOINT, PIPE JOINT SET, LID, PIPE JOINT CONNECTION METHOD, AND HOW TO USE LID
To reduce costs.SOLUTION: A pipe joint 40 connects: a primary lid cylindrical part 32 of a primary lid 21 including a primary lid body 31 which fits into a lid frame 3 provided on the upper end of a vertical pipe 2 and in which a fitting hole 33 that opens upward and downward is formed and the primary lid cylindrical part 32 that extends downward from the primary lid body 31; and a connection pipe 5 that is positioned above the primary lid cylindrical part 32. The pipe joint 40 includes: a first cylindrical part 41 that has a predetermined first diameter D1 and can be fitted into the primary lid cylindrical part 32; a second cylindrical part 42 that has a second diameter D2 smaller than the first diameter D1 and is positioned inside the first cylindrical part 41 in plan view; and a first connection part 47 that connects the first cylindrical part 41 and second cylindrical part 42.SELECTED DRAWING: Figure 2
【課題】コストを削減する。【解決手段】管継手４０は、立管２の上端に設けられた蓋枠３に嵌合し、上下に貫通した嵌合孔３３が形成された親蓋本体３１、および、親蓋本体３１から下方に向かって延びた親蓋筒状部３２を有する親蓋２１の親蓋筒状部３２と、親蓋筒状部３２の上方に配置される接続管５とを繋ぐ管継手である。管継手４０は、直径が所定の第１の直径Ｄ１であり、親蓋筒状部３２に嵌合可能な第１筒状部４１と、直径が第１の直径Ｄ１よりも小さい第２の直径Ｄ２であり、平面視において第１筒状部４１の内部に配置された第２筒状部４２と、第１筒状部４１と第２筒状部４２とを繋ぐ第１接続部４７と、を備えている。【選択図】図２
