RECEIVING FRAME-LID CONNECTION STRUCTURE FOR ABOVE-GROUND OPENING OF UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a connection structure for a receiving frame and a lid, the structure being capable of eliminating an inwardly protruding member on the inner peripheral surface of the receiving frame that may interfere with workers coming in and out of a manhole (an underground structure) or processes for bringing in and out an inner lid or machinery.SOLUTION: A receiving frame-lid connection structure is configured as a hinge structure A (one of the receiving frame-lid structures) having a connecting metal 5 inserted into a locking part 17 of a locking member 6 on the receiving frame side, the connecting metal serving as a locking member on the lid side, or as a locking structure B (one of the receiving frame-lid connection structures) having the locking part 17 of the locking member 6 on the receiving frame side fitted in a laterally long hole drilled through a hanging wall on the undersurface of a lid on an opening, the hanging wall serving as a locking member on the lid side. The locking part 17 is supported rotatably by an axis part 18 relative to a receiving frame 4. When a lid 2 on the opening is removed from the receiving frame 4 and the connecting metal 5 is removed from the locking part 17, or when the locking part 17 is disengaged with the laterally long hole 48, the locking part 17 protruding inwardly from the inner peripheral surface of the receiving frame 4 may be rotated and withdrawn into a storage space 35 formed in the receiving frame 4.
【課題】作業員がマンホール（地下空間構造物）内に出入りしたり、中蓋や機材を出し入れする際に、受枠の内周面から内側へ突出する部材を無くすることができる受枠・蓋間を結合する構造の提供。【解決手段】受枠側係合部材６の係合部１７に蓋側係合部材としての結合金物５を差し込んだ蝶番構造Ａ(受枠・蓋間結合構造の一つ)や、受枠側係合部材６の係合部１７を蓋側係合部材としての開口部蓋下面の垂下壁に設けた横長孔に嵌装させた施錠構造Ｂ(受枠・蓋間結合構造の一つ)に構成する。係合部１７は、受枠４に対して軸部１８で回転可能に支持され、開口部蓋２が受枠４から取り外されていて係合部１７から結合金物５が抜き取られた状態のときや係合部１７が前記の横長孔４８と係合から外された状態では、受枠４の内周面から内側に突出している前記係合部１７を回転させて受枠４に設けた収納空間３５に退避させることができる。【選択図】図２１
