LID RECEIVING FRAME SET FOR UNDERGROUND STRUCTURE
To provide a lid receiving frame for an underground structure which suppresses manufacture cost of a receiving frame, and achieves both suppression of rattling in a lid body and suppression of excessive biting of the lid body in a balanced manner.SOLUTION: In a lid receiving frame set 10, a frame body 31 of a receiving frame 3 has an inner peripheral surface 3111 which is provided in an inner peripheral part 311 of the frame body 31 and is inclined at a fixed angle in a direction of enlarging an inner diameter of the frame body 31 upward, an annular wall part 22 of a manhole lid 2 has an upper contact part 2211 and a lower contact part 2212 which are provided on an outer peripheral part 221 at an interval in a height direction, the upper contact part 2211 and the lower contact part 2212 are brought into contact with the inner peripheral surface 3111 in a lid closing state, and a lid rib 23 of the manhole lid 2 has a lower end in a part connected to the annular wall part 22 which is positioned above the lower contact part 2212.SELECTED DRAWING: Figure 3
【課題】受枠の製造コストを抑え、蓋体のガタツキの抑制と、蓋体の過剰な食い込みの抑制とをバランスよく両立し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の枠本体３１は、枠本体３１の内周部３１１に設けられ上方に向けて枠本体３１の内径が拡がる方向に一定の角度で傾斜した内周面３１１１を有するものであり、マンホール蓋２の環状壁部２２は、外周部分２２１に、高さ方向に間隔をあけて設けられた、上側接触部２２１１及び下側接触部２２１２を有するものであり、上側接触部２２１１と下側接触部２２１２は、閉蓋状態において、それぞれ内周面３１１１と接触し、マンホール蓋２の蓋リブ２３は、環状壁部２２に接続する部分の下端が、下側接触部２２１２よりも上方に位置するものである蓋受枠セット１０。【選択図】図３
