The first end 21 of the first roof panel 20a is arranged opposite to the second end 22 of the second roof panel 20b, the third area portion 221 is overlapped with the second area portion 212, and the third screw M3 penetrates the corresponding third area portion 221 and the second area portion 212 and is fixedly connected to the second purlin 50.

[0064] In the roof wall structure of the disclosed embodiment, the first end 21 of the first roof panel 20a is arranged opposite to the second end 22 of the second roof panel 20b, and the third area portion 221 is overlapped and connected with the second area portion 212. The installation of the roof panel is simple, which effectively reduces the installation difficulty and improves the construction efficiency. The third screw M3 penetrates the corresponding third area portion 221 and the second area portion 212 and is fixedly connected with the second purlin 50. With such an arrangement, the third screw M3 can simultaneously penetrate the metal sheet layers on both sides of the roof panel, thereby increasing the connection strength, improving the wind-resistant performance of the roof panel, and ensuring the stability of the roof.

[0065] Reference Figure 7 As shown, in one embodiment, the second area portion 212 and the third area portion 221 are located outside relative to the first area portion 211 and the fourth area portion 222. The outer surfaces of the third area portion 221 and the second area portion 212 form a recessed area relative to the outer surface of the roof panel 20, and the upper end head of the third screw M3 is located in the recessed area, and the height of the upper end head of the third screw M3 is less than the depth of the recessed area. With such a configuration, the upper end head of the third screw M3 is located in the recessed area, and the upper end head of the third screw M3 does not need to be directly exposed to the environment, thereby avoiding the cold bridge and thermal bridge effects of the third screw M3 and avoiding the appearance of condensed water at the upper end head position of the third screw M3.

[0066] Reference Figure 7 As shown, in one embodiment, a second waterproof covering sheet 70 is further included, and the second waterproof covering sheet 70 is arranged on the outer surface of the roof panel 20 along the first direction, and a plurality of third screws M3 are arranged along the first direction, and the second waterproof covering sheet 70 covers the third screws M3. Exemplarily, the second waterproof covering sheet 70 includes thermoplastic polyolefin, the roof panel 20 includes a first waterproof layer located on the outer surface, the first waterproof layer includes thermoplastic polyolefin, and the two side edges of the second waterproof covering sheet 70 are sealed and connected to the first waterproof layer by hot air welding. With such a configuration, the second waterproof covering sheet 70 can enclose the third screws M3 in a closed space to prevent liquid from flowing to the third screws M3, and can further prevent water seepage and leakage at the position of the third screws M3, thereby further improving the waterproof performance of the roof of the house wall structure.
