1、“延尺系数”问题书上及定额解释都不到位,实际上是指屋面斜边比水平边(投影边)长了多少倍的问题,图中C/A。说明不是“延迟系数”,是“延尺系数”。
2、“偶延尺系数”:在四坡屋面中有一条是二个斜屋面交接的斜边,这条斜边比水平边(不是该边的投影边)长多少倍就是称“偶延尺系数”,图中D/A。这种计算建立在四坡坡度相同的前提下。
3、坡度系数:=高度/底边*100%=H/A*100%=tan(18°)*100%=32.5%;
4、延尺系数:=斜边/底边=C/A=1/cos(18°)=1.0515。
5、偶延尺系数:双坡屋面二斜面的交接边/底边(不是投影的底边)=D/A=1/cosβ;β=atan(C/A)=atan(1/cosθ)=46.44°。偶延尺系数=1/cosβ=1.4511。
6、坡屋面的斜度表示常用三种方法:
⑴、角度法=θ;本题为18°
⑵、坡度系数法(也称百分法)=高度/底边*100%;本题为32.5%
⑶、比例法=1:(A/H);本题为1:3.08
