Specific embodiments

[0027] Such as Figures 1 to 3As shown in the figure, a steel-plastic connection structure and a steel-plastic grid using the same include a plurality of vertical grid bars 1 and horizontal grid bars 2 that are perpendicularly arranged and intersect. Preferably, the vertical grid bars 1 and the horizontal grid bars 2 are strip-shaped steel-plastic bars. The strip-shaped steel-plastic bars have excellent tensile strength and stiffness, can effectively withstand heavy loads and impacts, are suitable for use as load-bearing structures, are easy to cut and process, can be customized and adjusted according to engineering needs, are convenient to use in different construction environments, and the strip-shaped steel-plastic bars can effectively resist lateral and longitudinal forces in the soil, prevent phenomena such as slope landslides, and improve the overall stability of the soil mass. The intersection of the vertical grid bars 1 and the horizontal grid bars 2 is connected by a connecting device 3. The connecting device 3 includes a connecting nail 3a and an elastic conical ring 3b. The connecting nail 3a includes a first shaft 3a1, a second shaft 3a2, and a conical shaft 3a3 with diameters decreasing from top to bottom. Preferably, a corrosion-resistant layer is provided on the outer wall of the connecting nail 3a. The corrosion-resistant layer can effectively prevent the surface of the connecting nail from being eroded by moisture, chemical substances, and other corrosive factors, thereby extending the service life of the connecting nail, can enhance the overall strength and stability of the connecting nail to a certain extent, avoid a decrease in strength due to corrosion, ensure the safety of the structure, and using a connecting nail with a corrosion-resistant layer can significantly improve the durability of the entire structure. The corrosion-resistant layer can improve the performance of the connecting nail under extreme working conditions, reduce the risk of fracture and failure, and improve the overall reliability of the connection. The elastic conical ring 3b is fixedly installed on the conical shaft 3a3. Preferably, the cross-sectional shape of the elastic conical ring 3b is triangular and the large end faces the direction of the first shaft 3a1. Preferably, the material of the elastic conical ring 3b is rubber. Rubber has good elasticity, can deform when subjected to external forces and quickly return to its original shape, which enables the elastic conical ring to effectively absorb shocks and vibrations. The wear resistance of rubber enables the elastic conical ring to maintain good performance during long-term use, reduce wear and replacement frequency. The rubber material is relatively light, which helps to reduce the weight of the overall equipment, is convenient for installation and maintenance, and the rubber material is usually more economical, with lower production and maintenance costs compared to other materials. The distance between the elastic conical ring 3b and the first shaft 3a1 is not less than the sum of the thicknesses of the vertical grid bar 1 and the horizontal grid bar 2. The conical shaft 3a3, the elastic conical ring 3b, and the second shaft 3a2 sequentially pass through the vertical grid bar 1 and the horizontal grid bar 2 and limit the vertical grid bar 1 and the horizontal grid bar 2 between the first shaft 3a1 and the elastic conical ring 3b. For this steel-plastic connection structure and the steel-plastic grid using the same, through the provided connecting device, rapid connection of the steel-plastic grid can be achieved, thereby improving the structural expandability of the steel-plastic grid.

[0028] As Figures 1 to 3As shown, the connecting device 3 further includes a expansion sleeve 3c, and a third shaft 3a4, a tapered hole 3a6 and a straight hole 3a7 provided on the connecting pin 3a. The third shaft 3a4 is located at the bottom of the tapered shaft 3a3. The tapered hole 3a6 and the straight hole 3a7 are sequentially provided on the connecting pin 3a from top to bottom. The shape of the tapered hole 3a6 is adapted to the tapered shaft 3a3, and the shape of the straight hole 3a7 is adapted to the third shaft 3a4. The expansion sleeve 3c is fixedly provided on the third shaft 3a4. Preferably, there are 3 expansion sleeves 3c. Preferably, the cross-sectional shape of the expansion sleeve 3c is triangular. Preferably, the expansion sleeve 3c is made of polyurethane. When connecting steel-plastic grids, the third shaft of the upper steel-plastic grid can be closely fitted with the straight hole of the lower steel-plastic grid, thereby improving the connection strength of the connecting device. At the same time, the connection strength between the connecting device and the surface to be constructed can also be increased, improving the construction quality. The connecting pin 3a further includes a tip 3a5, and the tip 3a5 is provided at the bottom of the third shaft 3a4. By providing the expansion sleeve, the third shaft of the upper steel-plastic grid can be closely fitted with the straight hole of the lower steel-plastic grid, thereby improving the connection strength of the connecting device. By providing a tip at the bottom of the connecting pin, it is convenient to fix the steel-plastic grid to the surface to be constructed, improving the construction efficiency.

[0029] As Figures 1 to 3 shown, in use, the tapered shaft 3a3, the elastic tapered ring 3b and the second shaft 3a2 of the connecting pin 3a sequentially pass through the vertical grid bars 1 and the horizontal grid bars 2 and limit the vertical grid bars 1 and the horizontal grid bars 2 between the first shaft 3a1 and the elastic tapered ring 3b. Lay the steel-plastic grid on the surface to be constructed, and by rolling the steel-plastic grid, the tip 3a5, the third shaft 3a4 and the expansion sleeve 3c of the connecting pin 3a are pressed into the surface to be constructed, thereby fixing the steel-plastic grid to the surface to be constructed. When the steel-plastic grids need to be connected, the third shaft 3a4 and the expansion sleeve 3c in the connecting device 3 at the overlapping position of the upper steel-plastic grid are inserted into the straight hole 3a7 in the connecting device 3 of the lower steel-plastic grid, so that the upper steel-plastic grid and the lower steel-plastic grid are closely fitted. The steel-plastic connection structure and the steel-plastic grid using the same can realize the rapid connection of the steel-plastic grid through the provided connecting device, thereby improving the structural expandability of the steel-plastic grid. By providing the expansion sleeve, the third shaft of the upper steel-plastic grid can be closely fitted with the straight hole of the lower steel-plastic grid, thereby improving the connection strength of the connecting device. By providing a tip at the bottom of the connecting pin, it is convenient to fix the steel-plastic grid to the surface to be constructed, improving the construction efficiency.
