The roof panel system is subjected to wind resistance test, and the results are as follows:
TABLE 1 is the comparison table of the wind uplift resistance level and the wind pressure of the roof
Through the test of the wind resistance performance shown in the table above, when the thickness of the roof plate is 0.53mm, the wind resistance grade of the roof system exceeds 90PSF, the roof system can be used in the environment with extremely high wind pressure and extremely poor climatic conditions, and the wind pulling resistance can reach 4.3KN/m2。
Comparing the BIPV integrated photovoltaic roofing system of example 1 of the present invention with the existing commercially available BIPV (comparative) from the building base, based on the experimental and profile data, the following conclusions can be drawn:
1. heat preservation and heat dissipation performance:
the wave height of the comparative example was 84mm, and the wave height of example 1 was 103mm, which was about 19mm higher. The larger the gap between the photovoltaic panel and the bottom of the panel is, the better the heat dissipation performance is, but the wave height can be up to 103mm, and the structure of the invention ensures that the whole roof system is firmer, so that the roof system can bear higher wind resistance.
2. Wind resistance:
according to the wind resistance test data, the wind resistance data of the comparative example structure is 3.3KPa when the purlin distance is 1500mm and the plate thickness is 0.6mm, and the wind resistance data of the structure test data of the embodiment 1 of the invention is 4.3KPa when the purlin distance is 1500mm and the plate thickness is 0.53 mm.
3. Fire prevention and lightning protection:
4. Impact resistance:
5. Quality and cost performance:
the high elongation of the plate solves the problem of undercut of the plate, has the functions of high strength and thinning, has the same wind resistance, can be thinner, has the same plate thickness, and can improve the wind resistance. Because the two ribs in the middle of the invention adopt a buckling mode, and the two sides adopt an occlusion mode. By the method, the plate has better effective utilization rate, and the effective utilization rate of the comparative example is as follows: 73% for 730mm/1000mm, the effective utilization rate of this embodiment: 1043mm/1380mm is 75.5% utilization rate, the utilization rate is poor by 2.5%, and the price difference is about 2.5%, so the cost performance of the board of the embodiment is higher.
