高层建筑防排烟设计初探

随着我国城市建筑高层化、大型化、多功能化的蓬勃发展,在高层建筑中由于火患引起的危害也大大增加.高层建筑功能复杂,着火源和可燃物较多,一旦发生火灾,将使火势迅速蔓延,极易造成较大的损失及伤亡事故.本文初步介绍了高层建筑火灾特点,分析了影响防排烟系统的主要因素,并对高层建筑防排烟方面的问题进行了系统设计.

Preliminary probe of anti-smoke＇ s design for high rise building

With the development of city construction in China, the high-rise, large-sized and multi-functional buildings are booming. Under such status, the endangering caused by fire hazard is increasing sharply in high buildings. Owing to the complex function and massive ignition points/combustible included in such kind of blocks, once conflagration occurs, the fire will spread rapidly, which will lead to biggish damage and fatal accident easily. In this article the fire features in high-rise block were introduced, the main factors affecting anti-smoke system were analyzed, simultaneously, the settlements systematic for anti-smoke＇ s field was designed.
