[0002] Prefabricated airport pavement is an emerging paving technology. With its advantages of off-site prefabrication and on-site paving, this technology meets the needs of rapid maintenance and rapid paving at airports of all levels. Existing paving technologies mostly use prefabricated concrete pavement panels, but concrete prefabrication requires multiple construction processes to complete, the operation procedures are complicated, and the construction period is long. At the same time, when assembled on site, a single concrete pavement panel is often large in size. With the development of new materials, new processes, and new equipment, the use of pavement panels in the form of a combination of steel structure and composite materials not only greatly reduces the mass of a single pavement panel, but also reduces its external dimensions accordingly. However, when steel pavement panels are used as airport pavements, how to connect the steel pavement panels to avoid dents and warping of the prefabricated airport pavement is an important issue. At the same time, considering the problem of facilitating the replacement of damaged steel pavement panels, it is necessary to propose a steel pavement panel connection structure that can be easily disassembled and assembled.

[0033] The locking pin comprises a pin body 4 and two spring sheets 5 respectively arranged on both sides of the pin body 4;

[0034] Each side of the steel road panel 1 is provided with a semicircular groove 7 for installing the semicircular connecting block 2 and a rectangular groove 8 for the pin body 4 to pass through.

[0035] In actual use, a semicircular groove 7 and a rectangular groove 8 are provided on each side of the steel road panel 1, and the adjacent steel road panels are connected by snapping two semicircular connecting blocks 2 together. The rotation direction of the two semicircular connecting blocks 2 can be rotated to make the steel road panels detachable. When individual steel road panels are damaged and need to be replaced, they only need to be disassembled using tools, eliminating destructive disassembly work.

[0036] It should be noted that the locking pin cooperates with the rectangular groove 8 to lock and position the two semicircular connecting blocks 2 to achieve locking between the steel road panels, which can effectively ensure the quality of the steel road surface and prevent the steel road panels from being displaced at their connections due to stress.

[0037] In a specific implementation, the steel road panel 1 is a rectangular road panel, and two semicircular grooves 7 and a rectangular groove 8 are provided on each side of the steel road panel 1 .

[0038] like Figure 1 As shown, in this embodiment, the semicircular groove 7 is located in the middle of one side of the steel road panel 1, the rectangular groove 8 passes through the semicircular groove 7, and the rectangular groove 8 is connected to the upper and lower sides of the steel road panel 1.

[0039] In actual use, after two steel road panels are connected together, the rectangular grooves 8 of the two steel road panels are spliced ​​together to form a square groove, and the semicircular grooves 7 of the two steel road panels are spliced ​​together to form a circular groove.

[0040] During specific implementation, the semicircular groove 7 is located at a middle height position on one side of the steel track panel 1 .

[0041] like Figure 4 As shown, in this embodiment, a long strip groove 6 is respectively formed on both sides of the pin body 4.

[0042] In actual use, the long strip groove 6 is opened along the length direction of the pin body 4, and the pin body 4 is a cubic structure with a square cross section.

[0043] In specific implementation, the long strip groove 6 has one function as a mounting groove for the spring sheet 5 and another function to facilitate the staff to hook out the locking pin through the hook nail later.
