2, price is 542.8 yuan/m
2The cost of main frame material is 10 yuan/m
2So in the prior art, the cost of framework is 552.4 yuan/m
2
The size everywhere of the framework that the embodiment of the invention provides such as Fig. 8-shown in Figure 10, its cost is following:
The thickness of used galvanizing square tube is 2.0mm, and its consumption does
Pole: 240 * 2180 * 2 * 7.85=8.2Kg
Crossbeam: 240 * 1220 * 2 * 7.85=2.3Kg
More than add up to: 10.5Kg, i.e. every square of consumption 10.5 ÷ (1.300 * 2.180)=3.7Kg/m
2
Appraisal: 3.7Kg/m
2* 3.7 yuan/Kg=13.69 unit/m
2
Used 201 stainless thickness are 0.74mm, and its consumption does
Weight: 484 * 1300 * 0.74 * 7.93=3.7Kg
Every square of weight: 3.7Kg ÷ (1.300 * 2.180)=1.3Kg/m
2
Appraisal: 1.3Kg/m2 * 28 yuan/Kg=36.4 unit/m
2
The framework cost accounting that the embodiment of the invention provides is 50.09 yuan/m
2,, greatly reduce cost than existing framework.
