现浇钢筋混凝土斜屋面的设计构造和渗漏防治

设计斜坡屋面结构时,首先应选用合理的结构方案,建立合理的结构模型,尤其是采用PKPM结构软件设计时,荷载输入时一定要输入倾斜构件沿水平或垂直方向的荷载分量,而不是倾斜构件沿斜长方向的荷载分布(单位面积、单位长度内的荷载).配筋不当;为了追求建筑形式而将泛水高度过分的降低,使屋面与屋面连接处、屋面与墙身交接处的防水高度,低于下暴雨瞬时积水高度;屋面变坡处、老虎窗与屋面连接处等防水处理不当等都将成为屋面渗漏的隐患.

Design and Leakage Prevention of Pitched Roofing with Cast-in-place Reinforced Concrete

When designing the structure of pitched roofing,we should first select a sound plan and set up a good structural model,especially when we use PKPM(a structural design software application).When we input the weight loads,we should input vertical or horizontal data instead of the diagonal data.If we lower the water line excessively,making the waterproofing height lower than the rain reservation height,and we do not properly ensure waterproofing where the slope begins,where the dormer connects with the roof,leakage might be a hidden problem.
