Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a large-span sports stadium, including two base frames 1. The top wall of the base frame 1 has multiple locking slots 3. The top of the base frame 1 is provided with multiple support frames 4. The bottom left and right sides of the support frames 4 are respectively locked with the corresponding locking slots 3, so that the support frames 4 can be initially installed and connected under the locking of the locking slots 3. The front side of the locking slot 3 is provided with an installation groove 5. The inside of the support frame 4 is fixedly connected with a prestressed cable 6. The top left and right sides of the installation groove 5 are fixedly connected with connecting beams 7, thereby improving the connection strength of the support frame 4 through the prestressed cable 6. The top of the connecting beam 7 is fixedly connected with multiple steel beams 8. The top of the steel beam 8 is fixedly installed with a cover plate 12. Multiple fixing plates 10 are fixedly connected between the adjacent two locking slots 3. Then, the top height and stability of the stadium can be improved through the connecting beams 7 and steel beams 8.

[0040] Specifically, the interlocking connection between the base frame 1 and the support frame 4 ensures that the support frame 4 can be stably combined with the base frame 1, thus completing the initial installation of the support frame 4. The prestressed cables 6 are positioned and fixed inside the support frame 4 through the installation groove 5, which improves the stability and safety of multiple support frames 4 during the installation process. This not only meets the structural requirements of a large span, but also ensures the flexibility of the structure, allowing it to adapt to different building needs and environmental changes. Next, the tight connection between the connecting beam 7 and the steel beam 8 further strengthens the stability of the entire structure, enabling the height of the stadium to be increased without sacrificing the overall strength of the building. This not only achieves the effect of simplified construction, but also shortens the construction period, improves construction efficiency, and increases the service life of the building due to the stability and durability of the structure.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The weather-resistant structure 2 includes a modified bitumen roll 201. The outer wall of the modified bitumen roll 201 is fixedly connected to the bottom of the inner wall of the cover plate 12. Multiple fireproof boards 202 are fixedly connected to the bottom of the modified bitumen roll 201. The fire resistance of the bottom of the cover plate 12 can be improved by the modified bitumen roll 201 and the multiple fireproof boards 202. A connecting layer 203 is fixedly connected to the top of the modified bitumen roll 201. Multiple honeycomb holes 204 are opened on the top wall of the connecting layer 203. The connecting layer 203 improves the connection effect inside the cover plate 12 and increases the tightness. A gel board 205 is fixedly connected to the top of the connecting layer 203. Rock wool sandwich panels 206 are fixedly connected to the front and rear sides of the top of the gel board 205. Multiple waterproof boards 207 are fixedly connected to the top wall of the rock wool sandwich panel 206. The weather resistance of the cover plate 12 is improved by the rock wool sandwich panel 206 and the waterproof boards 207.

[0042] Specifically, by combining and fixing modified bitumen roll 201 with fireproof board 202, the fire resistance of the bottom of the cover plate 12 is improved. With the tight connection between rock wool sandwich panel 206 and multiple waterproof boards 207, the waterproof function of the cover plate 12 is realized, thereby further enhancing the overall weather resistance of the cover plate 12. Through the stable connection of the connecting layer 203, the overall connection strength inside the weather-resistant mechanism 2 is strengthened, the service life of the stadium roof is improved, and the frequency and cost of maintenance are effectively reduced.

[0043] Reference Figure 1 , Figure 4 and Figure 5 The weather-resistant mechanism 2 also includes a protective layer 208, the top wall of which is fixedly connected to the inner top wall of the cover plate 12; multiple connecting plates 209 are fixedly connected between the two adjacent rock wool sandwich panels 206, and the multiple connecting plates 209 are all rectangular in shape; fixing brackets 11 are fixedly connected to the left and right sides of the outer wall of the fixing plate 10, and the two fixing brackets 11 are symmetrically designed.

[0044] Specifically, the protective layer 208 provides protection for the top of the weather-resistant structure 2, the multiple connecting plates 209 enhance the connection strength of the rock wool sandwich panel 206, and the fixing frame 11 improves the external strength of the fixing plate 10.

[0045] Reference Figure 1 , Figure 2 and Figure 3 Multiple steel beams 8 are fixedly connected to multiple diagonal braces 9, forming a triangular support structure; multiple guide slots 13 are opened on the top of the cover plate 12, and the multiple guide slots 13 are opened at equal intervals; protective plates 14 are fixedly connected to the top left and right sides of the cover plate 12, and the bottom of the protective plates 14 is fixedly connected to the top of the base frame 1.

[0046] Specifically, the connection of multiple diagonal braces 9 improves the internal support effect of the steel beam 8, the multiple guide grooves 13 improve the rainwater guiding effect of the top of the cover plate 12, and the protective plate 14 can protect the bottom of the outer wall of the support frame 4.

[0047] Working principle: The initial installation of the support frame 4 is completed by the interlocking connection between the base frame 1 and the support frame 4. Then, the prestressed cable 6 is fixed inside the support frame 4, which improves the stability and safety when installing multiple support frames 4, and achieves the purpose of larger span and flexibility. Subsequently, the connection between the connecting beam 7 and the steel beam 8 can increase the height of the stadium while ensuring the overall strength of the building, achieving the effect of simplified construction, thereby shortening the construction cycle, improving construction efficiency and the service life of the building.

[0048] Furthermore, the fireproof effect at the bottom of the cover plate 12 is improved by connecting and fixing the modified bitumen roll 201 with the fireproof board 202. The waterproofing purpose is achieved by connecting the rock wool sandwich panel 206 with multiple waterproof boards 207, thereby improving the overall weather resistance of the cover plate 12. The connection strength of the weather-resistant mechanism 2 is improved by connecting the connecting layer 203, which increases the service life of the stadium roof and reduces the maintenance frequency and maintenance cost.
