二:雨蓬计算:

雨蓬计算简图如下:

1:截面尺寸:

根部:h≥L/12=1200/12=100mm,取h=100mm   

端部:h≥100×2/3=66.7mm,取h=70mm

竖板:b=60mm

2:荷载计算:

恒载:均布荷载:

20mm厚水泥砂浆面层:         0.02×20=0.4KN/M2

混凝土板(平均板厚为85mm):    0.085×25=2.13 KN/M2

20mm厚混合砂浆粉底:         0.02×17=0.34KN/M2            

file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtmlclip1/01/clip_image004.gif=2.87 KN/M2

集中荷载:

60mm厚砼现浇板:          0.06×25×0.38=0.57KN/M

20mm厚水泥砂浆双面粉:   2×0.02×20×0.38=0.304KN/M        

file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtmlclip1/01/clip_image004.gif=0.874KN/M

活载:

均布荷载:              qk=0.7KN/M

集中荷载:              P=1.0KN/M

取1m板宽作为计算单元:

g=1.2×2.87=3.44KN/M

G=1.2×0.874=1.05KN

Q均=1.4×0.7=0.98KN/M

Q集=1.4×1.0=1.4KN

3:内力计算:

file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtmlclip1/01/clip_image008.gif

取M=5.44KN·M

4:配筋计算:
