[0037] This specific embodiment provides a steel structure cooling tower carbon steel purlin aluminum alloy enclosure structure, including:

[0041] Thickened gasket 8, self-drilling and self-tapping screws 5 pass through the thickened gasket 8 to fix the corrugated plate 4 on the purlin 1, and the thickened gasket 8 is used to increase the force-bearing area of ​​the self-drilling and self-tapping screws 5 and the corrugated plate 4;

[0042] Fasteners 9, the vertical joints of the profiled plates 4 are connected by fasteners 9.

[0043] It should be noted that the thickened gasket 8 is used to increase the stress-bearing area of ​​the self-drilling and self-tapping screws 5 and the corrugated plate 4, which means that the thickness and diameter of the thickened gasket 8 are larger than those of the standard gasket, so that the stress-bearing area of ​​the self-drilling and self-tapping screws 5 and the corrugated plate 4 is increased, thereby avoiding shear and pull-off damage between the self-drilling and self-tapping screws 5 and the corrugated plate 4.

[0044] In actual use, the shape, structure, material, position, number, etc. of the purlin 1, corrugated plate 4, self-drilling and self-tapping screws 5, thickened gasket 8 and fasteners 9 can be determined according to actual conditions and actual needs.

Since the self-drilling and self-tapping screws 5 pass through the thickened gaskets 8 to fix the corrugated plate 4 on the purlins 1, the thickened gaskets 8 can effectively increase the force-bearing area of ​​the self-drilling and self-tapping screws 5 and the corrugated plate 4 to avoid wind damage caused by shearing and pulling between the self-drilling and self-tapping screws 5 and the corrugated plate 4, thereby improving the wind resistance of the device.
