合兴合肥钢结构浅谈钢结构厂房火灾特点

发布时间:2015-11-10 9:51:22 浏览次数:473

(1)空间大、蔓延快。大型钢结构厂房占地面积大,一般都是大高7米,内部空间大,空气好。其生产使用的原料及产品大部分属于可燃物;然后生产中大量使用的电气设备,处理过程中,首先真火火势向任何方向蔓延,燃烧,很容易发生猛烈的气流形成强烈的大面积的燃烧。


(2)设备和人员密集,火灾荷载大,产物。大型钢结构厂规模大的建筑结构-体全部生产机器设备密集,人员和货物的高度集中荷载大火灾,疏散通道少;火灾时烟气,工人们又长期的固定路线上下班。发生火灾时,很容易因为紧张形成趋群行为不利逃跑的产物,很容易的。


(3)搬运钢琴,升温快构建议强度减弱快容易倒塌。钢材常温下非燃烧材料,但钢材的导热系数。是的,混凝土,而钢琴构40种材质单一,所以火灾中成员很快。



(1) the space is large and the spread is fast. Large steel structure plant covers an area of large, generally are 7 meters high, the interior space is big, air is good. Most of the raw materials and products used in the production of combustible materials; and then a large number of electrical equipment used in the production process, the first true fire fire to spread in any direction, burning, it is easy to produce strong air flow into a large area of combustion.


(2) equipment and personnel intensive, fire load, product. Large steel structure plant size large construction structure - all production machinery and equipment intensive, personnel and goods are highly concentrated load large fire, the evacuation of the channel is less; fire smoke, workers and long-term fixed route to work. When a fire occurs, it is easy to form a product that is a result of the formation of a group that is not so easy to escape.


(three) carrying the piano, the rapid warming of the proposed strength weakened quickly collapse. The thermal conductivity coefficient of non combustible materials at room temperature. Yes, concrete, and the piano is a single 40 material, so the members of the fire quickly.
