OPENING PART STRUCTURE FOR UNDERGROUND SPACE STRUCTURE
PROBLEM TO BE SOLVED: To provide an opening part structure of an underground space structure having a locking mechanism unlockable even by any of tools used for versatilely used three types of locking mechanisms.SOLUTION: A cover is provided with a tool hole A capable of using first and second tools 28 and 29 and a tool hole B capable of using a third tool 30. A hook receiver 6 is provided on an inner surface of a receiving frame 4, and a lock member 15 is rotatably arranged on a reverse surface of the cover 3. The lock member 15 is provided with a lock member hook 21 for engaging with the hook receiver 6, a first passive part 19 and a second passive part 20. The lock member 15 is in a locking state where the lock member hook 21 provided in the lock member 15 is positioned just under the hook receiver 6 during normal time in which the cover 3 is closed, and is unlocked by any of the first to third tools inserted from the tool hole A or the tool hole B.
【課題】汎用されている３タイプの施錠機構に使用されている工具のいずれによっても解錠できる施錠機構を備えた地下空間構造物の開口部構造を提供する。【解決手段】蓋に第１、第２の工具２８，２９を使用できる工具孔Ａと第３の工具３０を使用できる工具孔Ｂとを設ける。受枠４の内面にフック受け６を設けると共に蓋３の裏面に錠部材１５を回動可能に配置する。錠部材１５には前記フック受け６に係合する錠部材フック２１と第１受動部１９、第２受動部２０を設ける。錠部材１５は、蓋３が閉じられている常時は錠部材１５に設けた錠部材フック２１が前記フック受け６の直下に位置した施錠状態にあり、前記工具孔Ａあるいは工具孔Ｂから挿し込まれる第１〜第３の工具のいずれかによって解錠される。【選択図】図１０
