LID-RECEIVING FRAME SET FOR UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a lid-receiving frame set for underground structure which can easily open a lid body when opening the lid body.SOLUTION: A receiving frame 3 has a frame side tapered surface 311 inclined outside toward the upper part provided in the inner peripheral side, has an abutted part 312 inclined the outside toward the upper part provided below the frame side tapered surface 311, has a manhole lid 2 inclined to the outside toward the upper part, has a lid side tapered surface 221 fitted into the frame side tapered surface 311 provided on the outer peripheral side, and has an abutting part 222 below the lid side tapered surface 221, and the abutting part 222 is abutted against the abutted part 312 when the lid body 3 is inclined relative to the upper end face 32 of the receiving frame 3 by a fixed angle, restricts inclination of the lid body 3 by the fixed angle or more, and has an outer peripheral surface inclined to the outside upwards with the same inclination angle as the abutted part 312.SELECTED DRAWING: Figure 4
【課題】蓋体を開ける際に容易に蓋体を開けることが出来る工夫がなされた地下構造物用蓋受枠セットを提供する。【解決手段】受枠３は、上方に向かうにつれて外側に傾斜した枠側テーパ面３１１が内周側に設けられ、枠側テーパ面３１１よりも下方に上方に向かうにつれて外側に傾斜した被当接部３１２を有し、マンホール蓋２は、上方に向かうにつれて外側に傾斜し、枠側テーパ面３１１に嵌合する蓋側テーパ面２２１が外周側に設けられ、蓋側テーパ面２２１よりも下方に当接部２２２を有し、当接部２２２は、受枠３の上端面３２に対して３蓋体が一定角度まで傾くと、被当接部３１２に当接し蓋体３が一定角度よりも傾くことを規制し、被当接部３１２と同様の傾斜角度で上方に向かうにつれて外側に傾斜した外周面を有するものである。【選択図】図４
