浅谈高层建筑竖向疏散通道防排烟问题

烟气毒害是阻碍人员疏散和实施救援行动、致使人员伤亡的主要原因之一,因此,做好高层建筑的防排烟设计,提高防排烟系统的实际效用,有着极其重要的意义。分析了高层建筑防排烟设计的重要性,并以竖向疏散通道防排烟系统设置为例,介绍了高层建筑防排烟设计工作中存在的问题以及相应的改善策略。

A Discussion on Smoke Control Problems with Vertical Smoke Evacuation Channels in High- rise Buildings

Toxic smoke is one of the major causes for impeding the evacuation and preventing the implementation of rescue operations,which results in serious human casualties. Therefore,a scientific smoke control design in high-rise buildings,which is to improve the practical effect of the smoke control system,is of significance. This paper analyzes the importance of smoke control system in high- rise buildings,and taking the setting of smoke control,exhaust systems in vertical evacuation channels as an example,this paper introduces the existing problems with the design of smoke control systems in high- rise buildings and the corresponding improvement strategies.
