寿县合兴浅谈轻钢结构厂房自动喷水灭火与防火分区

发布时间:2015-12-2 9:57:19 浏览次数:648

能否在整个车间设自动喷水灭火装置,使允许的防火分区面积增加一倍,从而满足规范要求呢。这有两个问题:


<1>. 单层轻钢结构车间的高度大多远超过8米,而根据<<自动喷灭火系统设计规范>>第4.3.2条,超过8米的大空间建筑物,安装闭式喷头的作用就不大了。


<2>. 有的丙类三级单层轻钢车间面积达9000平方米,需分三个防火分区,若全车间安装自喷,则防火分区允许面积虽扩大一倍,但仍然不够(安装自喷后,防火分区的允许面积从3000平方米扩大到6000平方米,但仍小于9000平方米)。


Can the whole workshop set up automatic spray fire extinguishing device, so that the fire partition area allows the fire to double, so as to meet the standard requirements. There are two questions:


<1>. single layer of light steel structure workshop is more than 8 meters high, and according to the automatic fire extinguishing system design specification article 4.3.2, more than 8 meters of large space buildings, the installation of closed type nozzle is not a big role.


<2>. some class C three single light steel workshop area of 9000 square meters, three fire district, if the whole workshop installation of sprinkler, fire partition area is allowed although doubled, but it's still not enough (after the installation of automatic sprinkler, fire partition area is allowed from 3000 square meters expanded to 6000 square meters, but still less than the 9000 square meters).
