公共建筑走道排烟设计探讨与分析

Discussion and Analysis on Smoke Exhausting System Design of Complex Corridor in Public Buildings

公共建筑的走道排烟系统是否能够有效运行,对于火灾发生时人员的安全疏散至关重要。现在一些大型公共建筑,走道的布局较为复杂,例如出现前后宽度不一致,形状不规则等情况。因此,走道排烟系统的设计越来越困难。本文重点分析走道长边长度的计算方法、走道局部宽度增大对排烟系统的影响及走道自然排烟三个问题并相应给出具体的解决方案。最后,以某实际项目为例,结合上述问题,给出了具体的排烟系统设计方案。

The effective operation of the smoke exhausting system of corridor in Public Buildings is essential for the safe evacuation of personnel in the case of a fire. The corridor layout of some large buildings is relatively complicated.For example, the width of the corridor is inconsistent, and the shape is irregular. Therefore, smoke exhausting system design of corridor is becoming more and more difficult. This paper focuses on the analysis of the calculation method of the length of the long side of the corridor, the influence of the increase of the local width of the corridor on the smoke exhausting system and the natural smoke exhaust from the corridor, and give specific solutions accordingly. Finally,taking a practical project as an example, combined with the above problems, the specific design scheme of smoke exhausting system is introduced.
