由于防排烟系统设计、建设以及维护费用较高,同时相关规范关于高层建筑防排烟系统设计的很多细节工作并没有标示清楚,因此,导致在高层建筑设计及建设过程中存在问题。本文首先说明了建筑防排烟的方式,然后分析了高层建筑防排烟设计中常见问题,最后详细阐述了高层建筑防排烟设计的对策。 Due to the high design, construction and maintenance costs of the smoke control system, many details concerning the design of smoke control systems for high-rise buildings are not clearly stated in the relevant norms, thus leading to problems in the design and construction of high-rise buildings. This paper first describes the ways of building smoke control, and then analyzes the common problems in smoke control design of high-rise buildings. Finally, it elaborates the countermeasures of smoke control design of high-rise buildings.
