按照预算定额的屋面工程量计算规则,瓦屋面工程量=图示尺寸的水平投影面积×坡屋面延尺系数,以平方米计算;卷材屋面工程量=图示尺寸的水平投影面积×屋面坡度延尺系数,以平方米计算;四坡水屋面斜脊长度=边长×隅延尺系数。关于延尺系数和隅延尺系数可查屋面坡度系数表。见表1。表1是在原表的基础上加以完
According to the rules for calculating the amount of roof work, the amount of tile roof = the horizontal projection area of the plot size × the roof extension coefficient of the slope, calculated in m2; the volume of the roof = the horizontal projection area of the plot size × the roof slope The coefficient of extension is calculated in square meters; the length of slope of water slope in Sipo is equal to the length of side and the coefficient of extension. About the extension coefficient and extension coefficient can be found roof slope coefficient table. See Table 1. Table 1 is based on the original table
