FLOATING BODY TYPE LIFTING GATE AND INSTALLATION METHOD OF THE SAME
To sufficiently suppress displacement (flexure) generated by a lifting force in a door body in a falling-down state.SOLUTION: A lifting gate 1 comprises: a door body 10 rotating and standing by buoyance of infiltrating water; an auxiliary driving portion 20 constantly applying a lifting force for supporting a standing operation of the door body 10 to both end portions in a width direction of the door body 10 in a falling-down state; two rod members 31a, 31b generating a bending moment acting against a bending moment generated by application of the lifting force by applying an axial force in the width direction to the door body 10 in the door body 10 in the falling-down state; and a turn buckle 33 capable of changing magnitude of the axial force.SELECTED DRAWING: Figure 5
【課題】倒伏状態の扉体において引き上げ力により生じる変位（曲げ）を十分に抑制すること。【解決手段】起伏ゲート１０は、浸入水の浮力によって回動し起立する扉体１０と、扉体１０の起立動作を補助するための引き上げ力を、倒伏状態の扉体１０の幅方向両端部に常時作用させる補助駆動部２０と、扉体１０にその幅方向の軸力を付与することによって、倒伏状態の扉体１０において引き上げ力の作用によって生じる曲げモーメントに抗する曲げモーメントを発生させる２つの棒部材３１ａ，３１ｂと、軸力の大きさを変更可能なターンバックル３３とを備えている。【選択図】図５
