COVER FOR UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a cover for an underground structure capable of stably holding a floatation locking state of a cover body, by surely preventing disconnection of engagement between a floatation lock member and a locking part of a receiving frame more than usual, when locked on the receiving frame in a state of floating the cover body by a constant height from the receiving frame, when uplift pressure is generated in the underground structure, by restraining the floatation lock member from abrading by vibration such as vehicle traffic time.SOLUTION: A circular arc-shaped part 63 having an external shape of a substantially circular arc shape is provided in a floatation lock member 60, and this circular arc-shaped part 63 is slidably held in the direction for copying after the external shape of the circular arc-shaped part 63 by a holding part 71 provided on an undersurface of a cover body 20. When the cover body 20 floats, one tip side locking claw part 61 of the floatation lock member 60 engages with a locking part 12 of a receiving frame 10, and an abutting part 62 on the other tip side of the floatation lock member 60 abuts on an abutting receiving part 72, so that a floatation locking state of the cover body 20 is stably held.SELECTED DRAWING: Figure 9
【課題】車両通行時等の振動によって浮上ロック部材が摩耗することを抑制し、地下構造物内に揚圧が発生し蓋本体が受枠から一定高さだけ浮上した状態で受枠に係止した際に、浮上ロック部材と受枠の係止部との係合が外れてしまうことを従来よりも確実に防止し、蓋本体の浮上係止状態を安定して保持することが可能な地下構造物用蓋を提供する。【解決手段】浮上ロック部材６０に外形が略円弧状の円弧状部６３を設け、この円弧状部６３を、蓋本体２０の下面に設けた保持部７１で、円弧状部６３の外形に倣う方向に摺動可能に保持する。蓋本体２０が浮上すると、浮上ロック部材６０の一方の先端側の係止用爪部６１が受枠１０の係止部１２に係合するとともに、浮上ロック部材６０の他方の先端側の当接部６２が当接受け部７２に当接することで、蓋本体２０の浮上係止状態が安定して保持される。【選択図】図９
