摘要
大型商业综合体具有文娱、购物、餐饮等功能,建筑本身体量大、面积大、人员密度大的特点。由于火灾荷载相对较高,火灾产生的烟雾浓度高、温度高、毒性大,烟气不易排出,导致人员逃生和救援人员施救困难。通过对现代大型商业综合体建筑的火灾烟雾流动规律和火场排烟时机选择进行分析,对有效开展大型商业综合体火灾排烟技术提出应用参考。
With the rapid development of the economy,large commercial complexes have come into being,with functions such as civic entertainment,shopping and dining,and the building itself is characterized by large volume,large area and high density of people.Due to the relatively high fire load,the smoke generated by fire is highly concentrated,hot and toxic,and the smoke is not easily discharged,which makes it difficult for people to escape and rescuers to give help.The article analyzes the fire smoke flow law and fire smoke evacuation timing of modem large commercial complex buildings,and proposes an application reference for effective fire smoke evacuation technology of large commercial complexes.
