___ "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。
