以某地下敞开式车库采用防火隔离带替代防火分隔为例,沿车库敞开面外墙挖掘一条沟渠以形成敞开式汽车库,通过模拟计算确定防火隔离带的宽度和自然排烟开洞面积的比例,沿防火隔离带两侧设置挡烟垂壁,并加密布置喷头。 Taking a fire-proof isolation zone instead of a fireproof partition for an underground open garage as an example, a ditch is excavated along the outer surface of the open garage to form an open garage. The ratio of the width of the firebreak to the area of ​​the natural smoke exhaust is determined through simulation , Set along both sides of the fire barrier block smoke wall, and layout of the nozzle encryption.
