HINGE DEVICE OF OPENING PART COVER FOR UNDERGROUND SPACE STRUCTURE
PROBLEM TO BE SOLVED: To provide a hinge device of an opening part cover for an underground space structure for easily inserting a hinge tool into a receiving seat, without being hindered by the existence of an intermediate cover, even if the hinge tool is sufficiently lengthened, in a hinge device of a manhole.SOLUTION: A receiving seat 6 on the receiving frame 4 side overhangs to the inside from an inner peripheral surface of a receiving frame 4, and comprises a long hole 16 long in the radial direction of the receiving frame 4. A hinge tool 5 on the opening part cover 2 side is a rod-like member vertically movably and rotatably inserted into the long hole 16 of the receiving seat 6, and is composed of an upper shaft part 17 and a lower shaft part 18, the upper end of the upper shaft part 17 is rotatably installed in an undersurface peripheral edge part of an opening part cover 2, the upper end of the lower shaft part 18 is rotatably installed on the inside on the lower end of the upper shaft part 17, and in a state of inserting the hinge tool 5 into the long hole 16 of the receiving seat 6, the lower shaft part 18 can be bent to the inside under the receiving seat 6.
【課題】マンホールの蝶番装置において蝶番具を十分に長くしても中蓋等の存在に邪魔されず、しかも蝶番具を受座に挿通し易い地下空間構造物用開口部蓋の蝶番装置を提供する。【解決手段】受枠４側の受座６は、受枠４の内周面から内側へ張り出し、受枠４の径方向に長い長孔１６を有し、開口部蓋２側の蝶番具５は、受座６の長孔１６へ上下移動及び回転可能に挿通される棒状の部材であって、上軸部１７と下軸部１８とから成り、上軸部１７の上端が開口部蓋２の下面周縁部に回転可能に取り付けられ、下軸部１８の上端が上軸部１７の下端に内側へ回転可能に取り付けられ、蝶番具５を受座６の長孔１６に挿通した状態で、下軸部１８を受座６の下方において内側へ折り曲げ可能としてある。【選択図】図３
