大空间建筑火灾探测、灭火及排烟研究概述

Research progress on fire detection,extinguishing,and smoke control in large space buildings

分析了大空间建筑(含高大空间及扁平大空间)的结构特点及其火灾探测与灭火难点,对大空间建筑的火灾探测、灭火及排烟现状进行了梳理,明确了适合于大空间建筑的火灾探测及灭火技术,比较了各国规范关于大空间建筑的防烟分区划分要求。基于探测、灭火及排烟方面的总结,最终提出了大空间建筑火灾研究的前沿问题:开发更加精准的探测及定位技术;研究高效烟气控制策略;发展新型防火隔烟技术。

This paper presents the structural characteristics and fire detection and suppression research issues of large space buildings(including high large space buildings and large flat space buildings).The current research status of fire detection,suppression,and smoke control strategy is clarified,and suitable detection and suppression technologies are proposed for large space buildings.Finally,the frontier issues,including research on more precise detection and positioning technologies,efficient smoke control strategies,and the development of new fire protection and smoke control technologies,are pointed out.
