FIREPROOF SHUTTER DEVICE FOR CONSTRUCTION
PROBLEM TO BE SOLVED: To close a notch part 6b for penetrating a seat plate 12 in a state where a blocking-up body 13 for sliding a guide rail 5 does not bite in the seat plate, in a fireproof shutter device for hanging down the guide rail 5 of a storage attitude by interlocking with descent of a shutter curtain 1.SOLUTION: A material for blocking up a both part 6b is formed as a movable piece 14d for rocking in an opening position for abutting on both end surface parts 12d in the seat plate longitudinal direction from a position for blocking up the notch part 6b, and the movable piece 14d is expansively opened-rocked in the opening position by receiving sliding resistance when abutting on both end surface parts 12d in the longitudinal direction when the movable piece 14d moves downward together with the seat plate, and the downward movement of the blocking-up body 13 is stopped by allowing the movable piece 14 to abut on a step difference projection part 6c provided in the notch part 6b, and abutment on both end surface parts 12d in the longitudinal direction is released, and the movable piece 14d changes an attitude to a blocking-up position thereby, and the blocking-up body 13 moves downward by releasing the abutment on both end surface parts 12d in the longitudinal direction of the movable body 14d together.
【課題】収納姿勢のガイドレール５が、シャッターカーテン１が下降することに連動して垂下するものにおいて、座板１２が貫通する切欠き部６ｂを、ガイドレール５をスライド移動する塞ぎ体１３が座板に食い込まない状態で閉鎖するようにする。【解決手段】切欠き部６ｂを塞ぐものを、切欠き部６ｂを塞ぐ位置から座板前後方向両端面部１２ｄに当接する開放位置に揺動する可動片１４ｄとし、該可動片１４ｄを、可動片１４ｄが座板と共に下動する際に前後方向両端面部１２ｄに当接するときの摺動抵抗を受けて開放位置に拡開揺動するようにし、切欠き部６ｂに設けた段差凸部６ｃに可動片１４が当接することで塞ぎ体１３の下動停止をして前後方向両端面部１２ｄとの当接を解除し、これにより可動片１４ｄが塞ぎ位置に変姿をし、合わせて可動体１４ｄの前後方向両端面部１２ｄとの当接解除をし塞ぎ体１３が下動するようにした。【選択図】図９
