摘要
环廊是大型展览类建筑内人员集散和通行的高大空间,在消防设计上常作为人员疏散的准安全区,关于环廊的排烟设计,我国尚无明确的有针对性的规定。本文以某典型环廊为例,对排烟系统设计方法进行研究,参照防火设计规范及NFPA92B模型,完成了自然排烟方式及机械排烟方式的系统设计,为同类建筑排烟系统设计提供参考。
The ring corridor is a high space for people gathering and dispersing and passing in buildings like large exhibition halls,which is designed frequently as a quasi-safe area for pedestrian evacuation in the fire protection. The smoke exhaust design of the ring corridor is not yet formulated a specific regulation in China. Therefore,we took one typical ring corridor as an example,focused on the research of design method of the smoke exhaust system,and achieved the system design of natural smoke exhaust mode and mechanical smoke exhaust mode according to the code for fire protection design of buildings and NFPA92B model. And it provided references for the design of smoke exhaust system in such kind of buildings.
