Zusammenfassung:PROBLEM TO BE SOLVED: To provide an inner sub-pipe joint which can be mounted on an inner wall surface of a manhole or an inlet.SOLUTION: An inner sub-pipe joint 10, mounted on an inner wall surface 102 of a manhole 100, comprises a waste water receiver 14 which receives waste water flowing from an inflow pipe 104 into the manhole 100. The waste water receiver 14 includes a reinforcing section 30 at an upper end section of a rear face 20 thereof, in an area where a reinforcing position 31, located at a predetermined distance below an upper end 22 of the waste water receiver 14, is included. Setting sections (insertion holes 50) for anchors are arranged at a predetermined dimension below the upper end 22 of the waste water receiver 14. The setting sections are arranged at positions lower than the reinforcing position 31 so as to have height different from that of the reinforcing position 31. 【構成】 内副管継手10は、マンホール100の内壁面102に取り付けて使用されるものであり、流入管102からマンホール100内に流入した下水を受ける下水受部14を備えている。下水受部14の上端22から所定距離下の位置にある補強位置31を含む範囲の下水受部14の背面20の上端部には、補強部30が設けられる。また、下水受部14の上端22から所定寸法下げた位置には、アンカの取り付け部(挿通孔50)が設けられており、この取り付け部は、補強位置31よりも低い位置に、補強位置31との間に高低差をつけた状態で配置されている。【効果】 内副管継手をマンホールや枡の内壁面に適切に取り付けることができる。【選択図】図1
