大空间建筑消防系统的设计

Design for Fire System of Large Space Building

大空间高层建筑的空间分隔大,防火分区多,设计中应针对不同条件,根据各消防系统的特点采用合适的灭火系统。各灭火系统还应该满足大空间建筑内火灾烟气模拟分析和疏散分析中提出的要求,即通过消防性能化的设计来确认各灭火系统在火灾中的作用。此外还阐述了工程设计体会,并指出需逐一计算各防火分区内消防系统同时使用的水量,得出一次火灾最大用水量。

The large space high-rise building is characterized by large spacing and more fire subareas. The proper fire extinguishing system shall be adopted according to different conditions and characteristics of each fire system. All extinguishing systems shall meet the requirement in making smoke simulation analysis and evacuation analysis, that is, the function of each fire extinguishing system in a fire disaster shall be confirmed through fire characterization design. The experiences in the engineering design were described, and it is proposed that total water consumption for all fire systems used simultaneously shall be added up, so as to obtain the maximum water consumption in one fire disaster.
