高层建筑的防火设计,应引起足够重视。本文仅就其中疏散楼梯的设计问题进行初步探讨。 在高层建筑中,平时的垂直交通运输主要是通过电梯来进行的。但在火灾时,除消防电梯外的一般电梯由于断电和不防烟火而失去作用,楼梯立即成为垂直安全疏散的最主要通道。因此设计好疏散楼梯十分重要。

The fire protection design of high-rise buildings should attract sufficient attention. This article will only discuss the design of the evacuation stairs. In high-rise buildings, the usual vertical transportation is mainly carried out through elevators. However, in the event of a fire, in addition to the general elevators outside the fire-fighting elevators, which lost their power and did not prevent fireworks, the stairs immediately became the most important passage for vertical safety evacuation. Therefore, it is very important to design evacuation stairs.
