In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] This embodiment provides a roof structure such as Figures 1 to 5 As shown, the roof structure includes a roof panel 1, a splicing assembly 2, and an edge banding member 3. The roof panel 1 includes a first roof panel 11 and a second roof panel 12; the splicing assembly 2 is provided at the joint between the first roof panel 11 and the second roof panel 12, and the splicing of the first roof panel 11 and the second roof panel 12 is achieved through the splicing assembly 2.

[0035] like Figure 1As shown, the first roof panel 11 includes a first bottom panel 111, a first insulation panel 112, a first top panel 113, and a first photovoltaic panel 114, arranged in sequence away from the indoor space. The first insulation panel 112 includes a first rock wool panel, a first vacuum insulation panel, and a second rock wool panel, arranged in sequence away from the indoor space. The second roof panel 12 includes a second bottom panel 121, a second insulation panel 122, a second top panel 123, and a second photovoltaic panel 124, arranged in sequence away from the indoor space. The second insulation panel 122 includes a third rock wool panel, a second vacuum insulation panel, and a fourth rock wool panel, arranged in sequence away from the indoor space. The photovoltaic panel includes a first photovoltaic panel 114 and a second photovoltaic panel 124, the top panel includes a first top panel 113 and a second top panel 123, and the top panel has a locking edge. The insulation panel includes a first insulation panel 112 and a second insulation panel 122, and the bottom panel includes a first bottom panel 111 and a second bottom panel 121. Providing the insulation panels can improve the thermal insulation performance of the roof structure.

[0036] like Figure 1 and Figure 3 As shown, the splicing assembly 2 includes a first splicing piece 21 and a second splicing piece 22. The first splicing piece 21 is connected to the first roof panel 11 and has a first snap-fitting portion 211. The second splicing piece 22 is connected to the second roof panel 12 and has a second snap-fitting portion 221. The first snap-fitting portion 211 and the second snap-fitting portion 221 are snap-fitted.

[0037] By providing the first splicing piece 21 and the second splicing piece 22, the first splicing piece 21 and the second splicing piece 22 are snap-fitted together through the first snap-fitting portion 211 and the second snap-fitting portion 221, which can facilitate the connection of the first roof panel 11 and the second roof panel 12, thereby improving the overall installation efficiency of the roof structure.

[0038] Among them, Figure 3 As shown, the first snap-fit ​​portion 211 can be connected to the first bottom plate 111 of the first roof panel 11 by riveting or bonding, and the second snap-fit ​​portion 221 can be connected to the second bottom plate 121 of the second roof panel 12 by riveting or bonding. As an alternative embodiment, the first snap-fit ​​portion 211 can be connected to the first bottom plate 111 of the first roof panel 11, or the second snap-fit ​​portion 221 can be connected to the second bottom plate 121 of the second roof panel 12. With the first snap-fit ​​portion 211 connected to the first bottom plate 111 and the second snap-fit ​​portion 221 connected to the second bottom plate 121, the first and second splicing pieces 21 and 22 can be more securely connected to the first and second roof panels 11 and 12.

[0039] See Figure 3The first snap-fitting portion 211 is convex, while the second snap-fitting portion 221 is concave. Alternatively, the second snap-fitting portion 221 may be convex and the first snap-fitting portion 211 may be concave. This combination of concave and convex engagement can enhance the secure connection between the first snap-fitting portion 211 and the second snap-fitting portion 221.

[0040] In this embodiment, the first splicing piece 21 is a first thermal insulation splicing piece. This serves to isolate heat transfer between the first roof panel 11 and the first splicing piece 21, preventing heat from the first roof panel 11 from being transferred to the first base plate 111 through the first splicing piece 21 and affecting the temperature of the space below the roof structure.

[0041] like Figure 1 、 Figure 3 and Figure 4 As shown, the first splicing piece 21 has a plurality of first extension connection portions 212. The first extension connection portions 212 extend toward the first roof panel 11. The first extension connection portions 212 can be connected to the first insulation board 112 of the first roof panel 11 by bonding or other means. The provision of the first extension connection portions 212 and the extension of the first extension connection portions 212 toward the first roof panel 11 can improve the reliability of the connection between the first splicing piece 21 and the insulation board, thereby improving the reliability of the connection between the first splicing piece 21 and the roof panel.

[0042] like Figure 3 and Figure 5 As shown, the second splicing piece 22 includes a second splicing body 23 and an assembly clip 24. The second splicing body 23 has a second extending connection portion 222 and a locking engagement portion 223. The assembly clip 24 can be connected to the second splicing body 23 by fastening means such as screws or other means, and has a second locking engagement portion 221. The assembly clip 24 can have a mounting hole at its bottom, into which fasteners such as screws or bolts can be positioned to securely connect the assembly clip 24 to the roof beam or purlin. The assembly clip 24 can also be welded to the roof beam or purlin.

[0043] like Figure 3As shown, the second extension connection portion 222 extends toward the second roof panel 12, and the second extension connection portion 222 can be connected to the second insulation board 122 of the second roof panel 12 by bonding or other means. By providing the second extension connection portion 222 and extending the second extension connection portion 222 toward the second roof panel 12, the reliability of the connection between the second splicing piece 22 and the second insulation board 122 can be improved, thereby improving the reliability of the connection between the second splicing piece 22 and the second roof panel 12. As an alternative embodiment, it can also be provided that: the first extension connection portion 212 can be connected to the first insulation board 112 of the first roof panel 11 by bonding or other means. And as Figure 1 and Figure 2 As shown, the locking portion 223 is located within the first locking portion 141 of the first top plate 113 and within the second locking portion 151 of the second top plate 123. By providing the locking portion 223, the first locking portion 141 and the second locking portion 151, the connection between the first top plate 113 and the second top plate 123 is tightened.

[0044] like Figure 5 As shown, the second splicing body 23 can be set as a split body, which includes a second heat-insulating splicing split 231 and a reinforcing support splicing split 232 which are sequentially arranged in a direction away from the room. The second heat-insulating splicing split 231 can be connected to the reinforcing support splicing split 232 by riveting or other means and has a second extended connection portion 222. The reinforcing support splicing split 232 has a second extended connection portion 222 and a lock edge fitting portion 223. By setting the reinforcing support splicing split 232, the strength of the second splicing body 23 can be improved to avoid the second splicing body 23 from having insufficient strength, which results in low wind resistance of the roof structure and damage to the roof structure in windy weather. As an alternative embodiment, such as Figure 3 As shown, the second splicing body 23 can also be formed as an integral part, and the second splicing body 23 can be a second thermal insulation splicing body. By providing the second thermal insulation splicing split body 231, or by configuring the second splicing body 23 as a second thermal insulation splicing body, heat transfer between the second roof panel 12 and the second splicing piece 22 can be isolated, preventing heat from the second roof panel 12 from being transferred to the second base plate 121 through the second splicing piece 22, thereby affecting the temperature of the space below the roof structure.

[0045] The edge sealing member 3 in this embodiment is provided at the joint of the roof panels. Figure 4 The edge seal 3 is located in the gap between the second insulation board 122, the second roof panel 12, and the splicing assembly 2. The edge seal 3 is made of polyurethane or other materials. This prevents water leakage caused by the gap by locating the edge seal 3 in the gap between the second insulation board 122, the second roof panel 12, and the splicing assembly 2.

[0046] In the installation process of a roof structure in this embodiment, during on-site installation, the installation position of the assembling clip 24 is first determined, and the assembling clip 24 is fixedly connected to the roof beam or purlin by bolts and other fixing parts. After the assembling clip 24 is installed on all roof beams or purlins from the ridge to the eaves, the second roof panel 12 is hoisted to a predetermined position, and the assembling clip 24 is connected to the second splicing body 23 by fixing parts such as screws. Then, the first splicing piece 21 on the first roof panel 11 is clamped with the assembling clip 24 on the second roof panel 12, thereby completing the connection between the bottom of the two roof panels, and then the first locking portion 141 and the second locking portion 151 on the first roof panel 11 and the second roof panel 12 are connected, thereby completing the connection between the top of the first roof panel 11 and the second roof panel 12.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
