防火卷帘门的位置与方式安装“考究”

防火卷帘门的位置与方式安装“考究”

防火卷帘门是安装在消防紧急疏散通道的隔热的,在火灾发生时防火卷帘门就起到很好的作用,能够很有效的把火势给隔离。但是针对防火卷帘门的安装位置那是很有讲究的,当火灾发生的时候人们往往会惊慌失措,若由于防火卷帘门关闭使疏散路线被堵,会增加人们的惊慌程度,导致意想不到的伤亡,既不利于安全疏散,也不利于消防人员陆人火场灭火。所以应尽量避免在疏散通道上设置防火门。
如必须在疏散通道上设置防火卷帘门,则应满足《高规》中“设在疏散通道上防火卷帘应在卷帘两则设置启闭装置,并具有自动、手动和机械控制的功能。”的要求,在联动设计上应采取两次控制下落方式,即在卷帘两则设专用的感烟及感温两种探测器,第一次由感烟探测器控制下落距地1.8m处停止,用以防止烟雾扩散至另一防火分区,第二次由感温探测器控制下落到底,以防止火灾蔓延。
