FIRE PROTECTION STRUCTURE OF SHUTTER
PROBLEM TO BE SOLVED: To provide a fire protection structure of a shutter that can be reduced in installation cost while improving fire protection performance.SOLUTION: The present invention relates to a fire protection structure of a shutter 1 configured to prevent flames from entering the indoor side of a building through the shutter 1 if a fire takes place outside the building with an opening part fully closed, in which thermally expansive fireproof members 90a, 90b are provided only in: a first region, where flames of a fire may enter the indoor side of the building with an opening part fully closed, of a region of a side face of a seat plate 31 provided atop of a shutter curtain 30 with the shutter curtain 30 opened and closed so as to close the opening part; and a second region including one of a region of the seat plate 31 on a closing-directional side for a stopper 34 fitted to an indoor-side side face of the building with the opening part fully closed, and a region that the stopper 34 having been molten with heat of the fire may enter.SELECTED DRAWING: Figure 3
【課題】防火性能を向上させながら、設置コストを低減することが可能になる、シャッターの防火構造を提供すること。【解決手段】シャッター１の防火構造は、開口部全閉状態において建物の屋外側で火災が発生した場合に、建物の屋内側にシャッター１を介して炎が侵入することを防止するための防火構造であって、開口部を閉鎖するようにシャッターカーテン３０を開閉させた際における当該シャッターカーテン３０の先端に設けられた座板３１の側面の領域のうち、開口部全閉状態において、火災の炎が建物の屋内側に侵入する可能性がある第１領域と、開口部全閉状態において、当該座板３１における建物の屋内側の側面に取り付けられたストッパ３４に対する閉鎖方向側の領域、又は火災の熱によって溶融したストッパ３４が流れ込む可能性がある領域の少なくともいずれか一方を含む第２領域とのみに、熱膨張耐火部材９０ａ、９０ｂを設けた。【選択図】図３
