COVER RECEIVING FRAME SET FOR UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a cover receiving frame set for an underground structure which suppresses the manufacturing cost of a receiving frame, and balances well with suppressing rattling of a cover body and suppressing excessive biting of the cover body.SOLUTION: A cover receiving frame set 10 is provided in which: a frame main body 31 of a receiving frame 3 has an inner peripheral surface 3111 provided on an inner peripheral portion 311 of the frame main body 31 and inclined at a certain angle in a direction in which the inner diameter of the frame main body 31 is expanded upward; an annular wall portion 22 of a manhole cover 2 has an upper contact portion 2211 and a lower contact portion 2212 provided in an outer peripheral portion 221 at intervals in the height direction; one of the upper contact portion 2211 and the lower contact portion 2212 makes surface contact with the inner peripheral surface 3111 in the closed state; and the other of the upper contact portion 2211 and the lower contact portion 2212 makes surface contact with the inner peripheral surface 3111 in the closed state, or linear contact with the inner peripheral surface 3111 in the circumferential direction of the inner peripheral surface 3111.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のうちの一方は、閉蓋状態において、内周面３１１１と面接触するものであり、上側接触部２２１１と下側接触部２２１２のうちの他方は、閉蓋状態において、内周面３１１１と面接触するもの、又は内周面３１１１の周方向において内周面３１１１と線状に接触する蓋受枠セット１０である。【選択図】図３
