SHIELD DOOR
To install a shield door that closes an opening when multiple blowout panels are opened in a building of a nuclear power plant so as not to interfere with the surroundings.SOLUTION: A shield door includes: an opening/closing plate for closing one opening after a plurality of blowout panels arranged in a building are opened; a frame body provided so that the opening/closing plate is rotatable and capable of being attached so as not to go out of an attachment range of a peripheral edge of the opening; opening means for maintaining the open state so that the opening/closing plate does not exist in a space extending the opening; and a sealing material interposed to seal the opening with the opening/closing plate when the opening means is released. The opening means comprises an elastic body for holding the opening/closing plate horizontally by locking it to a support material fixed to the frame body, and presses the opening/closing plate that has been disengaged from the support material against the sealing material after the blowout panel is opened.SELECTED DRAWING: Figure 1
【課題】原子力発電所の建屋などに複数配置されたブローアウトパネルが開放されたときに開口部を塞ぐための遮蔽扉を、周囲と干渉しないように設置する。【解決手段】遮蔽扉は、建屋に複数配置されたブローアウトパネルが開放された後の一の開口部を塞ぐための開閉板と、前記開閉板が回動可能に設けられ前記開口部の周縁の取付範囲にそこから出ないように取付可能な枠体と、前記開閉板が前記開口部を延長した空間に存在しないように開いた状態を維持する開手段と、前記開手段が解除されたときに前記開閉板で前記開口部を密閉するために介在させるシール材と、を有し、前記開手段は、前記枠体に固定された支持材に係止することで前記開閉板を水平に保持し、前記ブローアウトパネルが開放された後に前記支持材への係止が外れた前記開閉板を前記シール材に押し付けるための弾性体を備える。【選択図】図１
