传统的平屋面坡度为2%～3%,如果采用结构找坡,室内顶棚的倾斜明显,观感较差。而采用建筑找坡,尤其是单面坡,又耗用大量的珍珠岩块等轻质材料,造价较高。在某些住宅工程中,我们对原设计方案进行了改进。采用了“梯田式”结构做法(图1、2)。即根据坡度要求,各房间 The traditional flat roof slope is 2% to 3%. If the structure is used to find slopes, the inclination of the indoor roof is obvious and the perception is poor. The use of buildings to find slopes, especially single-sided slopes, consumes a lot of lighter materials such as perlite blocks, and the cost is relatively high. In some residential projects, we have improved the original design. The “terraced” structure was adopted (Figures 1, 2). That is, according to the slope requirements, each room
