某快件分拨中心建筑消防安全分析

Analysis on fire safety of mail distribution center

某快件分拨中心因分拨设备的连续性需要,防火分隔设置困难,疏散距离长。提出设置防火隔墙、防火卷帘、加强防火墙两侧屋顶承重结构的防火保护、自动报警联动切断输送机的电源等措施,提高消防安全性。设置火灾场景,以FDS模拟烟气蔓延;设置疏散场景,以PathFinder模拟人员疏散。对比模拟结果,验证分拨中心的防火设计方案的可行性。

As continuity of distribution equipment in a mail distribution center,its fire compartmentation setting is difficulty and evacuation distance is too long.Measurements are proposed such as setting of firewall or fireproof curtain,strengthening fire protection on load-bearing structure of roof besides firewall,and linking fire alarm and cutting power of transporter,in order to improve fire safety.Set fire scenes,smoke spread is simulated by FDS;set evacuation scenes,people evacuation is simulated by PathFinder.And simulation results are compared to assess fire safety plan.
