Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 延焼防止、遮熱、遮煙が可能となること。 【解決手段】 建物の東西南北には、それぞれウォータ ーミストノズル9a〜9dが設けられる。各ウォーター ミストノズル9a〜9dは電磁弁5a〜5dを介して貯 水タンク1に接続されている。西の隣家で火災が発生す ると各ウォーターミストノズル9b近傍に設けられた温 度検知センサ30bで温度検知され集中制御装置20に 出力される。集中制御装置20は検出された方向の電磁 弁5bを開きウォーターミストノズル9bからウォータ ーミストを噴霧し建物の延焼を防止する。各方向のウォ ーターミストノズル9bは噴霧範囲が一部重なるように 複数個所定間隔で配置され連続した防火区域を形成す る。 (57) [Summary] [Problem] To be able to prevent spread of fire, heat and smoke. SOLUTION: Water mist nozzles 9a to 9d are provided on the east, west, south and north of the building, respectively. Each of the water mist nozzles 9a to 9d is connected to the water storage tank 1 via solenoid valves 5a to 5d. When a fire occurs in the west neighbor, the temperature is detected by a temperature detection sensor 30b provided near each water mist nozzle 9b and output to the centralized control device 20. The central control device 20 opens the electromagnetic valve 5b in the detected direction and sprays water mist from the water mist nozzle 9b to prevent the building from spreading. A plurality of water mist nozzles 9b in each direction are arranged at predetermined intervals so as to partially overlap the spray range to form a continuous fire protection zone.
