CLOSING DEVICE FOR NUCLEAR POWER FACILITY
To enable holding an open state even if a large load is applied in a vertical direction, and to achieve a layout that allows a pressure inside a building to be easily released in an abnormal situation, in a case where a plurality of shielding doors are arranged close to each other.SOLUTION: A closing device 1 includes shafts 31c and 32c extending in a vertical direction provided between a shielding door 10 and a frame-type frame 20, and hinges 31 and 32 that support the shielding door 10 in a rotatable manner. A driving device 40 is provided at a side of the shielding door 10, in a lower position relative to a vertical direction center part of the shielding door 10.SELECTED DRAWING: Figure 5
【課題】上下方向に大きな荷重が作用しても開放状態で保持できるようにし、しかも、複数の遮蔽扉を互いに接近させて配設する場合に、異常事態が発生したときの建屋の内部の圧力を逃がしやすいレイアウトを実現可能にする。【解決手段】閉止装置１は、遮蔽扉１０と枠型フレーム２０との間に介在し、上下方向に延びる軸３１ｃ、３２ｃを有し、遮蔽扉１０を回動可能に支持するヒンジ３１、３２を有している。遮蔽扉１０の側方には、遮蔽扉１０の上下方向中央部よりも下寄りに駆動装置４０が配設されている。【選択図】図５
