For example, the waterproof closing member 20 and the thermal insulation material are arranged behind the main structure of the ridge. For the thermal insulation material, the waterproof closing member 20 is located on the side facing the inside of the building, and the thermal insulation material is located on the side facing the outside of the building.

The two sides of the third waterproof covering sheet 50 can also be connected by other sealing methods. With such a structure, the third waterproof covering sheet 50 can be arranged above the waterproof closing member 20 to achieve full sealing at the ridge position. The third waterproof covering sheet 50 cooperates with the waterproof closing member 20 at the slit position to form a closed waterproof whole, thereby avoiding water seepage and leakage at the slit position of the main structure of the ridge, further improving the waterproof performance of the roof structure, and improving the bearing capacity, thermal insulation performance and sealing performance of the ridge position of the roof structure. Moreover, the third waterproof covering sheet 50 can also protect the thermal insulation material located in the groove 24 to avoid damage to the thermal insulation material by people stepping on it.

The third area portion 121 is overlapped with the second area portion 112, the first screw 63 penetrates the corresponding third area portion 121 and the second area portion 112 and is fixedly connected to the first purlin 61, and the second screw 64 penetrates the corresponding third area portion 121 and the second area portion 112 and is fixedly connected to the second purlin 62.

[0064] In the roof structure of the embodiment of the present disclosure, the first end 110 of the third roof panel 10c is arranged opposite to the second end 120 of the fourth roof panel 10d, and the third area portion 121 is overlapped with the second area portion 112. The installation of the roof panel is simple, which effectively reduces the installation difficulty and improves the construction efficiency. The first screw 63 penetrates the corresponding third area portion 121 and the second area portion 112 and is fixedly connected to the first purlin 61, and the second screw 64 penetrates the corresponding third area portion 121 and the second area portion 112 and is fixedly connected to the second purlin 62. With such an arrangement, the first screw 63 and the second screw 64 can penetrate the metal plate layers on both sides of the roof panel at the same time, thereby increasing the connection strength, improving the wind-resistant performance of the roof panel, and ensuring the stability of the roof structure.

[0065] Reference Figure 6 and Figure 7As shown, in one embodiment, the first area portion 111 and the third area portion 121 are located outside relative to the second area portion 112 and the fourth area portion 122, the outer surface of the third area portion 121 forms a recessed area relative to the outer surface of the main body of the roof panel 10, the upper ends of the first screw 63 and the second screw 64 are both located in the recessed area, and the height of the upper ends of the first screw 63 and the second screw 64 is less than the depth of the recessed area. With such a configuration, the first screw 63 and the second screw 64 are formed in the recessed area, and the upper ends of the first screw 63 and the second screw 64 do not need to be directly exposed outdoors, which reduces the cold bridge and thermal bridge effects of the first screw 63 and the second screw 64, and avoids the appearance of condensed water at the upper ends of the first screw 63 and the second screw 64.

[0066] Reference Figure 6 and Figure 7 As shown, in one embodiment, the roof structure also includes a second waterproof covering sheet 65, which is arranged on the outer surface of the roof panel 10 along the second direction Y, and a plurality of first screws 63 and a plurality of second screws 64 are arranged along the second direction Y, and the second waterproof covering sheet 65 covers the first screws 63 and the second screws 64.

[0067] Exemplarily, the second waterproof covering sheet 65 includes a thermoplastic polyolefin material, the roof panel 10 includes a first waterproof layer, the first waterproof layer includes a thermoplastic polyolefin material, the second waterproof covering sheet 65 covers the first screw 63 and the second screw 64, and the two side edges of the second waterproof covering sheet 65 are sealed and connected to the first waterproof layer by hot air welding. With such a configuration, the second waterproof covering sheet 65 can enclose the first screw 63 and the second screw 64 in a closed space, prevent liquid from flowing to the first screw 63 and the second screw 64, further prevent water seepage at the position of the first screw 63 and the second screw 64, and further improve the waterproof performance of the roof structure.
