Description

TECHNICAL FIELD

[0001] The utility model relates to a large-span metal roof system, in particular to a roof system structure with high wind resistance. BACKGROUND

[0002] With the continuous development of cold-formed thin-walled technology, large-span metal roof systems are increasingly widely used in industrial and civil buildings, such as stadiums, airport terminals, theaters, and stadiums. From the early metal roof panels, which mostly used traditional penetrating fixing methods, to the current hidden fixing methods of buckling and biting, these roof systems still have some problems in the application process, such as being blown over by the wind and leaking. To enhance the wind resistance of the roof system, a continuous welding stainless steel roof system was introduced, but the cost was too high, and it was mainly used in coastal areas. In addition, some wind-resistant clips were used to enhance the wind resistance of the roof system, but the wind-resistant clips in the freely deformable roof system also caused problems such as wear caused by temperature effects. Therefore, it is necessary to take economic and effective measures to improve the wind resistance of the roof system.

[0003] Moreover, in the related art, to improve the wind resistance of the roof system, the connection strength between the roof panel and the support is strengthened by using wind-resistant clips and continuous welding, but these strengthening methods have relatively complex structures and high costs, and may cause new problems. SUMMARY

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0012] Preferably, the longitudinal section of the fastening member is left-right symmetrical, upper long and lower short in the shape of an I-beam.

[0013] Therefore, the fastening member can form a two-way fastening connection structure with the left hook portion of the second roof panel, thereby further improving the wind resistance of the roof system.

[0014] Preferably, the longitudinal section of the supporting member is trapezoidal in shape, which can more stably support the entire roof system.

[0024] Secondly, the utility model adopts the clamping member 3 which is a I-shaped member with a longitudinal section arranged left and right symmetrically, upper long and lower short, and can form a clamping connection structure in two layers with the left hook part 2-1 of the second roof panel 2, so as to further improve the wind resistance of the roof system.
