BRANCH PIPE CONNECTION MEMBER
To provide a branch pipe connection member capable of suppressing deterioration of workability due to accumulation or biting of foreign matter such as earth and sand, in a member capable of switching between a deformed state of being bent and deformed during construction and a stretched state.SOLUTION: A branch pipe connection member 10 has an inner surface fixing part 20 and a branch pipe joint part 40. The inner surface fixing part 20 comprises two curved pieces 22 curved along an inner peripheral surface 1a of a main pipe 1, and a connection part 24 that rotatably connects the two curved pieces 22 around a rotation axis C; and can be switched between a stretched state and a deformed state. The rotation axis C of the connection part 24 is provided at a position offset from the curved piece 22 to a position deviated from the curvature center side of the curved piece 22 in the stretched state.SELECTED DRAWING: Figure 1
【課題】施工に際して屈曲変形した変形状態と、伸長状態とに切り替え可能な部材において、土砂等の異物が堆積したり噛み込んだりすることによる施工性の低下を抑制可能な枝管接続部材を提供することを目的とする。【解決手段】枝管接続部材１０は、内面固定部２０と、枝管継手部４０とを有する。内面固定部２０は、本管１の内周面１ａに沿うように湾曲した２つの湾曲片２２と、２つの湾曲片２２を回動軸心Ｃを中心に回動可能に連結する連結部２４とを備えており、伸長状態と変形状態とに切り替え可能とされている。連結部２４の回動軸心Ｃは、伸長状態において湾曲片２２に対して湾曲片２２の曲率中心側に外れた位置にオフセットした位置に設けられている。【選択図】図１
