1.屋面荷載
1)平屋面 h=120mm
20厚1:3水泥砂漿找平層 20×0.02=0.40 KN/㎡
高聚物改性瀝青防水卷材 0.50KN/㎡
30mm厚1:3水泥砂漿Φ4@200雙向配筋 25×0.03=0.75KN/㎡
35厚無溶劑聚氨硬泡保溫層 4×0.035=0.14 KN/㎡
1:8水泥膨脹珍珠巖找坡2%最小40厚 2.5×(0.04+4.2×0.02/2)=0.21 KN/㎡
120厚鋼筋混凝土板 25×0.12=3.0 KN/㎡
涂料頂棚 0. 5 KN/㎡
屋面恒荷載合計 gk =5.5 KN/㎡ 取5.5 KN/㎡
屋面活載 qk =0.5 KN/㎡
屋面荷載: 5.5+0.5=6.0KN/㎡
屋面荷載設(shè)計值 5.5×1.2+0.5×1.4=7.3 KN/㎡
