LID BODY RECEIVING FRAME FOR UNDERGROUND STRUCTURE
To provide a lid body receiving frame for an underground structure that is designed to prevent unexpected damage to an anticorrosive sheet in installation construction of a receiving body and allow easy inspection of maintenance management.SOLUTION: A receiving frame 3 which defines an opening H connected to an underground structure and in which the opening is closed by a lid body 2, has a metallic frame body 5 having an inner peripheral surface 511 sloped downward in the direction of an inner diameter getting small, and an anticorrosive sheet 7 provided on the inner peripheral surface 511 with the lid body 2 coming into face contact thereto in a lid-closed state. Color of the frame body 5 is black, and the color of a front face 72 of the anticorrosive sheet 7 is different from the color of the frame body 5.SELECTED DRAWING: Figure 2
【課題】受枠の設置工事等における防食用シートの不用意な損傷を防止し、さらに維持管理の点検を容易にする工夫がなされた地下構造物用蓋体受枠を提供する。【解決手段】地下構造物につながる開口Ｈを画定し、蓋体２によって閉蓋されることで開口が塞がれる受枠３において、下方に向けて内径が狭くなる方向に傾斜した内周面５１１を有する金属性の枠本体５と、内周面５１１に設けられ、閉蓋状態において蓋体２が面接触する防食用シート７と、を備え、枠本体５が黒色のものであり、防食用シート７は、おもて面７２が枠本体５と色が異なるものである。【選択図】図２
