SHIELDING DOOR
To prevent a chain for opening/closing a shielding door from being slackened and cut off due to vibration such as an earthquake.SOLUTION: A shielding door 200 installed at an open position where it does not overlap a blow-out panel covering an opening 120 of a building and slidable to a closed position so as to cover the opening 120 after opening of the blow-out panel comprises a chain cut-off prevention device that prevents a chain from being cut off following vibration of the shielding door 200 by maintaining the pulled state of the chain pulled tense for sliding the shielding door 200 by a spring so as to absorb slackening of the chain.SELECTED DRAWING: Figure 1
【課題】遮蔽扉を開閉させるためのチェーンが弛んで地震等の振動により切断されるのを防止する。【解決手段】建屋の開口部１２０を塞いでいるブローアウトパネルと重ならない開位置に設けられ、ブローアウトパネルが開放された後に開口部１２０を塞ぐように閉位置までスライド移動可能な遮蔽扉２００であって、遮蔽扉２００をスライド移動させるために張ったチェーンを、付勢したバネにより引っ張った状態を維持することで、チェーンの弛みを吸収し、遮蔽扉２００の振動に伴うチェーンの切断を防止するチェーン切れ防止装置を備える、ことを特徴とする。【選択図】図１
