[0027] Specifically, a splicing plate 26 is fixedly connected to the surface of the card block 24, and a rain shield 27 is fixedly connected to the surface of the splicing plate 26.

[0028] The effects achieved by the above components are as follows: by setting the splicing plate 26, multiple roof panels 22 can be spliced ​​together in an orderly manner by means of the connection between the clip 24 and the slot 23, so that the roof forms a continuous and complete whole, effectively expanding the roof coverage area; the rain shield 27 can directly block the rainwater from eroding the splicing of the roof panels 22, significantly reducing the risk of rainwater leakage, protecting the internal structure of the roof from rainwater erosion, and maintaining the stability of the roof structure.

[0029] Specifically, the surface of the rain shield 27 is provided with a guide groove 28, and there are two clips 24, which are fixedly connected to the two sides of the splicing plate 26 respectively.

[0030] The effects achieved by the above components are as follows: by setting the guide channel 28, rainwater can be guided to flow quickly in a specific direction, avoiding the accumulation of rainwater on the surface of the rain shelter 27; the two clips 24 are fixed on both sides of the splicing plate 26, providing support and fixation for the connection between the splicing plate 26 and the roof panel 22 from both sides, greatly enhancing the stability of the splicing joint and ensuring the integrity of the overall roof structure.

[0031] Specifically, sealing sleeves 25 are also fixedly connected to both sides of the rain shield 27. The surface of the sealing sleeve 25 is engaged with the other rain shield 27. A fixing plate 29 is fixedly connected to the bottom of the support frame 21.

[0032] The effects achieved by the above components are as follows: by setting the sealing sleeves 25 on both sides of the rain shield 27 to abut and engage with another rain shield 27, the sealing effect at the splice of the rain shield 27 is further enhanced; the fixing plate 29 provides a larger contact area for the connection between the support frame 21 and the building body 1, ensuring the stability and safety of the connection between the building body 1 and the roof device 2.

[0033] Specifically, a screw 210 is inserted and connected to the top of the fixing plate 29, and the surface of the screw 210 is inserted and connected to the top of the building body 1. The surfaces of the roof panel 22 and the splicing plate 26 are provided with screw grooves 211, and the inner wall of the screw groove 211 is threaded with a screw rod 212. The surface of the screw rod 212 is threaded with a limit nut 213.

[0034] The effects achieved by the above components are as follows: by setting screws 210 to insert and connect the fixing plate 29 and the top of the building body 1, the connection between the support frame 21 and the building body 1 is further tightened; the screw grooves 211 opened on the surface of the roof panel 22 and the splicing plate 26 are threadedly connected to the screw 212 and then tightened by the limiting nut 213, which further enhances the stability of the splicing point of the roof panel 22 and the splicing plate 26 and effectively improves the overall performance of the roof.

[0035] Specifically, the insulation device 3 includes a cavity inside the roof panel 22, with a fiberglass wool board 31 fixedly connected to the inner wall of the cavity, and rock wool 32 fixedly connected to the surface of the fiberglass wool board 31.

[0036] The effects achieved by the above components are as follows: by setting the glass fiber cotton board 31, heat can be effectively blocked from being conducted through the roof panel 22, thus playing a preliminary role in heat preservation; the rock wool 32 and the glass fiber cotton board 31 work together to further improve the heat preservation effect of the roof.

[0037] Specifically, the surface of the rock wool 32 is fixedly connected with an aerogel felt 33, and the glass fiber cotton board 31, rock wool 32 and aerogel felt 33 are fixedly connected to each other.

[0038] The effect achieved by the above components is that by setting the aerogel felt 33 to be fixedly connected with the glass fiber cotton board 31 and rock wool 32, a multi-layer composite thermal insulation structure is formed, which can more effectively maintain the stability of indoor temperature and reduce energy consumption caused by the temperature difference between indoor and outdoor.

[0039] Working principle: By setting up the roof device 2, the inverted V-shaped support frame 21 is fixed to the top of the building 1. Utilizing the stability principle of triangles, the roof pressure can be distributed more efficiently, greatly enhancing the overall stability of the roof under large span spaces and better coping with complex environmental pressures. The roof panel 22, made of lightweight materials, effectively reduces the roof's self-weight, which is conducive to the optimization of the overall building structure. The slots 23 on both sides of the roof panel 22 are connected to the blocks 24, and with the sealing sleeves 25, convenient installation is achieved while ensuring good waterproof and dustproof performance. The splicing plate 26 is spliced ​​with the roof panel 22 through the blocks 24 to expand the coverage area. The rain eaves 27 and their guide channels 28, as well as the abutting connection of the sealing sleeves 25 between the rain eaves 27, construct multiple waterproof barriers and significantly improve the roof's waterproof effect. The screw grooves 211, screws 212, and limit nuts 213 on the surfaces of the roof panel 22 and the splicing plate 26 further enhance the stability of the splicing point.

[0040] By installing the insulation device 3, glass fiber cotton board 31, rock wool 32 and aerogel felt 33 are installed in the cavity inside the roof panel 22. The three are fixed together to form a multi-layer composite insulation structure. The glass fiber cotton board 31 and rock wool 32 have heat insulation and heat preservation properties, while the aerogel felt 33 can more effectively reduce the exchange of heat between indoors and outdoors, reduce building energy consumption, and create a more comfortable environment for the interior of large-span buildings, which is in line with the development trend of green buildings.
