___ "1200mm*4000mm"。

Within a unit。

the ___ to the structure by three M8*80 metal ___ used in this project is made of C30 concrete。

Based on experiments。

the allowable n value of M8*80 metal n bolts anchored on 150# (C15 concrete) concrete is 540kg。

If M8*80 metal n bolts are anchored on C30 concrete。

___ value will be much larger than 540kg。

This n sheet takes the 540kg allowable n value on 150# concrete as an example。

The allowable n value of the three M8*80 metal ___ 3×540kg=___ layer and the structure is only gravity and n。

the n force is equal to the total weight force。

which is F拉=F总重
=Gg=1620kg×9.8N/kg=N=15.876KN。

The formula used is F=Gg (g=9.8N/kg).
Analysis of the total weight of the ___:
1.L40×4 galvanized ___ 4.68kg/m。

There are 6 tubes with a length of 1.7m in a representative unit。

so G L40×4 galvanized ___=4.68kg/m×1.7m×6=47.736kg。

F1= G L40×4 galvanized square tube g= 467.8128N≈0.4678KN.
2.L50×5 ___
3.77kg/m。

There are 2 tubes with a length of
4m in a representative unit。

so G L50×5
___3.77kg/m×4m×2=30.16kg。

F2= G L50×5 ___
295.568N≈0.2956KN.
3.1200mm*2440mm ___ unit。

the area of the plywood processed with a light trough is 0.6m×1.2m=0.72m2.There are two light troughs in a representative unit。

so M灯
=0.72m2×2=1.44m2.The area of a single plywood board is
1.2m×
2.44m=2.928m2.Therefore。

G细木工板=30kg。

and the weight of plywood per square meter is approximately
10.246kg/m2.Thus。

G3=10.246kg/m2×1.44m2=14.754kg。

F3= G3 g= 144.5892N≈0.1446KN.
4.1200mm*3000mm ___ unit。

the area of the gypsum board is 1.2m×3m=3.6m2.and the weight of a single gypsum board is 34.2kg。

Therefore。

the weight of gypsum board per square meter is G石膏板=34.2kg÷3.6m2=9.5kg/m2.nally。

gypsum boards are also used to seal the two sides of the light trough。

so the area of the gypsum board is ___.
代表单元内石膏板面积为5.76平方米，计算得到重量
G4=46.56千克，对应的力为F4=G4g=0.4563千牛。

针对C60*27*0.6龙骨，代表单元内共计17根，重量
G5=11.742千克，对应的力为F5=G5g=0.1151千牛。

吊顶转换层各卡扣配件及刷料等总重量约为3.4千克，对
应的力为F6=G6g=0.0333千牛。

综合以上计算，总向下拉力为F总
=F1+F2+F3+F4+F5+F6=1.5127千牛。

由于F总=1.5127千牛远远小于F拉=15.876千牛，即向
下荷载小于总拉力允许值的一半以上，因此吊顶转换层承重符合安全要求。

根据以上计算，1200mm×4000mm模数内吊顶材料总重力
为F总=1.5127千牛，则在1000mm×1000mm范围内，
F=1.5127千牛÷（1.2m×4m）×（1m×1m）≈0.3151千牛/平方米。
