疏散走道自然排烟系统设计研究

Study on Design of Natural Smoke Exhaust System in Evacuation Walkway

自然排烟系统的设计是包含建筑专业在内,全专业配合完成的工作。为了使各专业能协调该系统的工作任务,提高设计成果的质量,进而提高自然排烟系统的安全可靠性,笔者通过在工作中的工程设计经验、与审图老师及同行的交流学习、在工地现场验收的心得,并翻阅对比了各类规范标准文件,将个人的经验和见解组织整理成文。本文针对现行国家标准自然排烟系统的设计要求,对应工程案例中常遇到的疑义和问题,探讨疏散走道自然排烟设计中遇到的一些问题,进而提出个人见解。

The design of the natural smoke exhaust system is a professional work requiring the coordination of various disciplines,including the architecture. In order to coordinate the work of the system by different disciplines, to improve the quality of the design results, and to enhance the safety and reliability of the natural smoke exhaust system, through the experience in engineering design, the exchange and study with the drawing examination teacher and colleague and the experience of site inspection, the author checked and compared various standard documents and norms, and organized into a document according to personal experience and opinion.According to the design requirements of the current national standard natural smoke exhaust system, in view of the common questions and doubts in the engineering cases, this paper discussed some problems in the design of natural smoke exhaust for evacuation walkways, and put forward some personal opinions.
