遮雨顶棚对厂房建筑消防安全的影响

Influence of rainshelter on warehouse fire safety

针对某印刷生产厂房之间设置遮雨顶棚的火灾危险性进行分析,重点对火灾时遮雨顶棚影响相邻建筑之间火灾蔓延及建筑防排烟问题进行研究。利用FDS对设定的火灾场景进行模拟分析。结果表明,火灾不会以热辐射的方式通过设有遮雨顶棚的通道蔓延,当遮雨顶棚采用的阳光板燃烧性能为B1级及以上材料时,火灾不会以热传导的方式通过遮雨顶棚蔓延,遮雨顶棚下聚集的烟气不会对人员疏散和火灾扑救造成不利影响。

Analysis were made on fire risks of rainshelter between printing plants, and mainly analyzed fire spread between adjacent buildings and smoke spread problems. FDS is used to simulate set fire scenarios. The results showed that fire did not spread through channel under the rainshelter by heat radiation; when the combustion performance of the rainshelter board was B1 class or above, fire did not spread through rainshelter by heat conduction, and smoke accumulated under the rainshelter did not have an adverse effect on people evacuation and fire fighting.
