自然排烟方式是建筑防排烟系统设计的重要组成部分。而自然排烟系统目前尚无专门的国家标准,给工程设计、施工及验收带来了困难,同时一些常见的不规范做法也给工程带来了安全隐患。本文从自然排烟的技术原理、影响因素、设计要点及在大空间场所的应用等方面进行探讨和分析,为自然排烟方式的合理应用献计献策。
Natural smoke exhaust mode is an important part of the design of smoke control system. At present, there is no specific national standard for natural smoke exhaust system, which brings difficulties to engineering design, construction and acceptance. At the same time, some common non-standard practices also bring security risks to the project. This article explores and analyzes the technical principles, influencing factors, design points and applications of natural smoke exhaust in natural gas, and provides suggestions for the rational application of natural smoke exhaust.
