[0036] As Figs. 1 to 4 shown:

[0037] Embodiment 1: basic stair reinforcing structure.

[0038] The embodiment provides a basic stair reinforcing structure, which comprises two curved supports 1, each curved support being composed of a top rod 11 and two L-shaped supporting rods 12. A first reinforcing rod 4, a second reinforcing rod 5 and a connecting device 6 are sequentially assembled from top to bottom in the curved support 1. A stable assembly 2 is formed by a plurality of transverse rods 21 and longitudinal rods 22 which are arranged in a crisscross manner to form a steel mesh sheet assembled on the top of the curved support 1. The connecting device 6 comprises a first connecting assembly 61 and a second connecting assembly 62, which are arranged in a cross shape and are welded to the curved support 1 through an arc-shaped connecting plate 602. An adjusting assembly 3 is assembled between the center points of the first connecting assembly 61 and the second connecting assembly 62, and comprises a first fixing rod 31, a threaded rod 32, a sleeve rod 33, a fixing piece 34 and a second fixing rod 35, and is used for adjusting the overall stability of the stair reinforcing structure.

[0039] Embodiment 2: Stair reinforcing structure with supporting structure.

[0040] The embodiment improves the second reinforcing rod 5 on the basis of the embodiment 1, and adds a supporting structure 7. The supporting structure comprises a U-shaped steel bar 71 and a connecting rod 72, the U-shaped steel bar 71 is welded to the outer side wall of the second reinforcing rod 5, and the connecting rod 72 is used for connecting the U-shaped steel bars 71 to form a stable supporting system. The design further enhances the overall stability and anti-deformation ability of the stair reinforcing structure.

[0041] Embodiment 3: Stair reinforcing structure with multiple reinforcing rods.

[0042] The embodiment increases the number of the first reinforcing rods 4 on the basis of the embodiment 1. The first reinforcing rods are provided in plurality and are uniformly arranged below the top rod 11. The design improves the overall rigidity and stability of the stair reinforcing structure, so that the stair reinforcing structure can better bear the load on the stairs.

[0043] Embodiment 4: Stair reinforcing structure with adjustable height. The embodiment provides a stair reinforcing structure with adjustable height, which is mainly realized through an adjusting assembly 3. The adjusting assembly 3 comprises a first fixing rod 31, a threaded rod 32, a sleeve rod 33, a fixing piece 34 and a second fixing rod 35, wherein the threaded rod 32 is in threaded connection with the sleeve rod 33. By rotating the threaded rod 32, the height of the sleeve rod 33 can be adjusted, and then the height of the entire stair reinforcing structure is adjusted. The design enables the stair reinforcing structure to be flexibly adjusted according to the height and inclination of different stairs, and improves the applicability and practicability of the stair reinforcing structure.

[0044] Embodiment 5: Comprehensive optimization of stair reinforcing structure.

[0045] The embodiment integrates the advantages of embodiments 1 to 4, and provides a comprehensive and optimized stair reinforcing structure. The structure not only has stable curved supports 1 and connecting devices 6, but also increases the support structure 7 and the design of several reinforcing rods, while realizing the function of height adjustment. This comprehensive and optimized stair reinforcing structure not only improves the load-bearing capacity and safety of the stairs, but also makes it more flexible and practical.

[0046] The installation steps of the stair reinforcing structure are as follows: first, six horizontal rods 21 and seven vertical rods 22 are welded together to form a steel mesh, and the steel mesh is welded to the top of the curved support 1. When the stairs bear vertical loads such as walking and carrying heavy objects, the steel mesh can resist the tensile stress caused by bending, thereby enhancing the overall bending resistance.

[0047] Then, the positions of the two connecting devices 6 are adjusted so that the first connecting assembly 61 and the second connecting assembly 62 are arranged in a cross shape. The adjusting assembly moves the sleeve rod 33 up and down under the action of the threads by rotating the threaded rod 32, and the second fixed rod 35 moves upward under the action of the fixing piece 34, thereby adjusting the distance between the first connecting assembly 61 and the second connecting assembly 62. It is ensured that the connecting device 6 can accurately connect the curved support 1, and the connecting rod 601 and the arc-shaped connecting plate 602 can effectively transfer and distribute the load, avoiding deformation or damage of the single curved support 1 due to excessive stress.

[0048] Among them, the two curved supports 1 can effectively resist shear force at the junction of the stairs and the ground. When the stairs bear vertical loads, the steps will bend and deform, and the three first reinforcing rods 4 and the two second reinforcing rods 5 can resist the tensile stress caused by bending, avoiding excessive deformation or fracture of the steps during use.

[0049] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the above specific embodiments. Any modification of the function and structure principle without deviating from the present application will be included in the scope of the claims.
