[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example 1

[0033] This embodiment provides a connecting structure 1 for assembling road surfaces, such as... Figures 1-2 As shown, it includes: baffle 11 and connecting rod 12.

[0034] The baffle 11 has a longitudinally extending spiral structure, and the connecting rod 12 is longitudinally inserted into the baffle 11, so that the baffle 11 extends longitudinally around the circumference of the connecting rod 12. In the specific implementation process, after several connecting rods 12 are anchored into the roadbed, the baffles 11 on each connecting rod 12 are embedded in the roadbed. Then, several pavement units 2 are connected to the connecting rods 12. When a vehicle moves from one pavement unit 2 to another, the load on the pavement unit 2 is distributed to the roadbed through the baffles 11 on the connecting rods 12. Specifically, when the pavement unit 2 has an upward / downward tilting tendency, the interaction force between the baffle 11 and the roadbed can improve the reliability of the connection between the pavement unit 2 and the roadbed, reduce the risk of uneven settlement of the pavement unit 2 due to vibration, and thus improve the overall stability and practical effect.

[0035] In this embodiment, as Figure 1 or Figure 2 As shown, the lower end of the connecting rod 12 has a tapered structure with a gradually decreasing cross-sectional area from top to bottom. This structure facilitates the anchoring of the connecting rod 12 into the roadbed by workers from the upper end.

[0036] In this embodiment, as Figure 1 Combination Figure 2 As shown, the upper end of the connecting rod 12 is fitted with a load-bearing plate 13 by means of welding, screwing, or molding, and the road surface unit 2 is connected to the load-bearing plate 13. This structure facilitates workers to use a pile driver to hammer the load-bearing plate 13 on the connecting rod 12 to anchor the connecting rod 12 into the roadbed.

[0037] In this embodiment, as Figure 1 Combination Figure 2As shown, the pavement assembly connection structure 1 also includes a connection component 14. This connection component 142 includes a connection plate 141 and a connecting member 142. Connecting rods 12 are connected to the underside of the connection plate 141 by welding, screwing, or other methods. Multiple connecting rods 12 can be provided, arranged along the length of the connection plate 141 to improve the reliability of the connection between the connection plate 141 and the roadbed. Threaded holes 15 are provided on the connection plate 141. Multiple threaded holes 15 can be provided, arranged along the length of the connection plate 141. The number of connecting members 142 corresponds to the number of threaded holes 15. Each connecting member 142 passes through the pavement unit 2, and each connecting member 142 is connected one-to-one to the threaded hole 15 on the connection plate 141. This structure achieves the purpose of fixing the pavement unit 2 to the connecting rods 12 using the connection component 14.

[0038] In this embodiment, as Figure 1 Combination Figure 2 As shown, a limiting plate 16 is welded, screwed, or integrally formed onto the connecting plate 141. A right-angle groove 17 is formed between the limiting plate 16 and the connecting plate 141, and this right-angle groove 17 is used to fit against the road surface unit 2. In specific implementation, when the road surface unit 2 is placed on the connecting plate 141, the end of the road surface unit 2 can fit precisely into the right-angle groove 17, and the lower wall of the road surface unit 2 fits against the connecting plate 141, while the side wall of the road surface unit 2 fits against the limiting plate 16. This structure facilitates the installation of the road surface unit 2 by allowing workers to use the right-angle groove 17 between the connecting plate 141 and the limiting plate 16 to limit its position for subsequent fixing. Simultaneously, it increases the strength of the connecting plate 141.

[0039] In this embodiment, as Figure 2 As shown, the limiting plate 16 is located in the middle of the connecting plate 141 and extends along the length of the connecting plate 141. The threaded holes 15 on the connecting plate 141 are symmetrically distributed on both sides of the limiting plate 16. This structure achieves the purpose of fixing two adjacent road surface units 2 on both sides of the connecting plate 141.

[0040] Example 2

[0041] This embodiment provides an assembled road surface, such as Figures 3-6As shown, the system includes a road surface unit 2 and a connecting structure 1 as described in Embodiment 1. There are at least two connecting structures 1, all arranged in parallel, with a road surface unit 2 positioned between any two adjacent connecting structures 1. First connecting holes 21 are evenly distributed on both sides of the surface of the road surface unit 2. These first connecting holes 21 on both sides of the road surface unit 2 correspond to threaded holes 15 on either side of the connecting structure 1. A connector 142 passes through each first connecting hole 21 of the road surface unit 2, and each connector 142 in the first connecting hole 21 is screwed into a threaded hole 15 on the connecting plate 141. This structure achieves the purpose of fixing the road surface unit 2 to the connecting structure 1. Simultaneously, it allows for the connection of various road surface units 2 to form the desired road surface.

[0042] In this embodiment, as Figure 3 and Figure 4 As shown, the edges of the road surface unit 2 are evenly provided with second connecting holes 22, which are used to install lifting rings. This structure facilitates the installation of lifting rings on the road surface unit 2 by workers for hoisting the road surface unit 2. Simultaneously, the even distribution of the second connecting holes 22 on the road surface unit 2 improves the stability of the road surface unit 2 during hoisting.

[0043] Example 3

[0044] This embodiment provides a construction method, such as Figure 7 As shown, the installation of the assembled road surface described in Example 2 includes the following steps:

[0045] SA. Determine the anchoring positions of the connecting rods on the roadbed; specifically, first determine the number of connecting rods needed based on the length of the roadbed, then determine the installation position of the first connecting rod on the roadbed, and then determine the installation positions of the remaining connecting rods based on the length of the pavement unit.

[0046] SB. Anchor the connecting rod into the roadbed;

[0047] SC. Fix the connecting plate to the load-bearing plate of the connecting rod;

[0048] SD. Hoist the road surface unit between any two adjacent connecting rods, so that one side of the road surface unit is located in the right-angle groove of the connecting plate on one connecting rod, and the other side of the road surface unit is located in the right-angle groove of the connecting plate on another connecting rod;

[0049] SE. Screw the connector from the first connecting hole of the road surface unit into the corresponding threaded hole.
