Specifically, two adjacent bridge deck main bodies in the transverse direction are combined into one body through the above-mentioned transverse connectors, and two adjacent bridge deck main bodies in the longitudinal direction are combined into one body through the above-mentioned longitudinal connectors.

[0031] Adopting this structure, through the above-mentioned transverse connectors and longitudinal connections, multiple above-mentioned bridge deck main bodies are combined and connected horizontally and longitudinally into one body. Even if the bridge body vibrates and shakes, it is not easy to fall off. There is no need for welding, the installation is simple, the stiffness of the bridge deck is reduced, the overall stability is higher, the bridge deck is flatter and more stable, making the practicality of the present utility model stronger.

[0032] As a specific implementation manner of this embodiment, as Figure 5 shown, the above-mentioned bridge deck main body includes a steel frame 1 and a bridge plate 2 covering the above-mentioned steel frame 1. The above-mentioned bridge plate 2 is fixed to the above-mentioned steel frame 1 by spot welding. Side plates 3 are provided on both sides of the above-mentioned steel frame 1 in the width direction. The above-mentioned side plates 3 are welded and fixed to the steel frame 1. The above-mentioned side plates 3 are preferably I-beams with better structural strength.

[0033] In this embodiment, as Figure 1 and Figure 2 shown, the above-mentioned transverse connector includes a first bolt 7, a first nut 8, and two limiting pieces 9.

The two above-mentioned limiting pieces 9 are sleeved on the above-mentioned first bolt 7. One above-mentioned limiting piece 9 is located between the first bolt 7 and one of the side plates 3, and the other above-mentioned limiting piece 9 is located between the other side plate 3 and the first nut 8. Among them, the two above-mentioned limiting pieces 9 can be welded and fixed to the first bolt 7 and the second nut 8 respectively into one body.

One above-mentioned transverse connector is inserted through two corresponding first through holes 4 on two adjacent above-mentioned side plates 3, thereby improving the stability of the horizontal connection of the two above-mentioned bridge deck main bodies.

[0035] In this embodiment, as Figure 2As shown, in order to further prevent the first bolt 7 from loosening, two circular holes 10 are provided around each first through hole 4 of the side plate 3, and the two circular holes 10 are centrally symmetrical with the first through hole 4 as the center of the circle, and also include a second bolt 11 and a second nut 12.

At the same time, the limiting plate 9 is symmetrically provided with two flying wings, and the two circular holes 10 interfere with the flying wings in the circumferential direction, so that the flying wings of the limiting plate 9 can be blocked by the second bolt 11 to prevent the limiting plate 9 from rotating, thereby preventing the first bolt 7 from rotating and loosening.

[0036] Further, such as Figure 3 and Figure 4 As shown, the longitudinal connecting member includes a third bolt 13, a latch 14, and a transverse plate 15 and two longitudinal plates 16 connected in a "N" shape.

At the same time, The above-mentioned transverse plate 15 is tightly attached to the top of the two above-mentioned closing plates 5, and the lower end of the above-mentioned longitudinal plate 16 extends to a position below the bottom of the above-mentioned closing plates 5. The lower end of the above-mentioned longitudinal plate 16 is provided with a second through hole 18, and the end of the above-mentioned third bolt 13 is provided with a pin hole 19. After the above-mentioned third bolt 13 crosses the second through holes 18 of the two above-mentioned longitudinal plates 16, the above-mentioned pin 14 is inserted into the pin hole 19 at the end of the above-mentioned third bolt 13, so that the above-mentioned longitudinal connecting member completely clamps the two above-mentioned closing plates 5 through the transverse plate 15, the two longitudinal plates 16 and the third bolt 13, so that the two above-mentioned bridge deck bodies are longitudinally connected and combined into one.

[0037] It is worth noting that Figure 5 As shown, a support plate 24 and a limit plate 25 are welded and fixed to the position of the steel frame 1 near the groove 6.

[0039] As an optimization, it further includes triangular gusset plates 21. The above-mentioned triangular gusset plates 21 are provided on one side of the above-mentioned longitudinal plates 16 away from the clamping plates 17. The above-mentioned triangular gusset plates 21 are connected between the longitudinal plates 16 and the cross plate 15, and the above-mentioned triangular gusset plates 21 play a role in enhancing the structural strength and bearing capacity of the longitudinal connectors.

[0040] In this embodiment, the number of the above-mentioned grooves 6 is two, and the two above-mentioned grooves 6 are evenly and spaced along the length direction of the sealing plate 5. A longitudinal connector is installed in the two grooves 6 corresponding to the positions on two adjacent above-mentioned sealing plates 5, so as to improve the stability of the longitudinal connection between the two above-mentioned bridge deck bodies.

[0041] As a specific implementation manner of this embodiment, as Figure 5 shown, the above-mentioned steel frame 1 includes strip steel 22 and connecting channel steel 23. A plurality of the above-mentioned strip steels 22 are arranged in parallel and at intervals. The above-mentioned strip steels 22 are preferably I-beams. A plurality of the above-mentioned connecting channel steels 23 are welded in parallel and at intervals between two adjacent above-mentioned strip steels 22. The above-mentioned bridge plate 2 is welded and fixed on the above-mentioned steel frame 1. The overall structure of the above-mentioned steel frame 1 effectively bears the load distribution of the above-mentioned bridge plate 2, and the overall stability is high.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
