To enable fire extinction in a facility having a high ceiling and structurally large space area such as a warehouse, in which fire can be suppressed while reducing loss of water.SOLUTION: A plurality of sheet developing device 14 are provided in a grid-like manner on an upper plane of a large protective space 12 such as a warehouse. The sheet developing devices 14 holds a partitioning sheet 36 wound in a rolled manner, and vertically develops the partitioning sheet 36 by falling while fixing one end of the sheet when the holding of the partitioning sheet 36 is released by an operational signal from the outside. A sheet development control part provided to a fire receiving panel and the like outputs an operational signal to the plurality of sheet developing devices 14 positioned so as to surround a target area A5 in which fire occurs in the warehouse which is a fire break-out position in the event of fire, vertically develops the partitioning sheet 36 to close by surrounding the target area A5, suppresses emission of fire, smoke, and heat to outside, sprays fire extinguishing agent from a fire extinguishing head 18, and sprays cool water from a cooling agent spraying head to a sheet surface.SELECTED DRAWING: Figure 4
【課題】倉庫等の天井が高く、さらに構造上、空間面積の大きい施設を対象に、水損を抑えつつ確実に火災の抑制消火を可能とする。【解決手段】倉庫等の大きな防護空間１２の上部平面に格子状に複数のシート展開装置１４が配置される。シート展開装置１４は、ロール状に巻き回された仕切シート３６を保持し、外部からの作動信号により仕切シート３６の保持を解除したときに、仕切シート３６の一端を固定した状態で落下させることにより上下に展開させる。火災受信盤等に設けられたシート展開制御部は、火災時に、火災発生場所となる倉庫内の火災が発生した対象区画Ａ５を囲むように位置する複数のシート展開装置１４に作動信号を出力し、対象区画Ａ５を囲むように仕切シート３６を上下に展開して閉鎖させ、炎、煙及び熱の外部への放出を抑制し、消火ヘッド１８から消火剤を散布させ、冷却剤散布ヘッドからシート面に冷却水を散布する。【選択図】図４
