[0026] In some preferred embodiments, first through holes are provided on both sides of the channel plate 1 in the longitudinal bridge direction; the longitudinal limiting rod 5 penetrates through and is arranged in the first through holes and abuts against the expansion joint wall. In this design, first through holes are provided on both sides of the channel plate 1 in the longitudinal bridge direction, and the longitudinal limiting rod 5 penetrates through and is arranged in these through holes and abuts against the expansion joint wall.

Through its sliding connection and abutting function, it can effectively transfer the supporting force and load to the ground, increasing the stability of the overall structure. The telescopic assembly 62 includes a screw pipe 621 and an adjusting screw 622. The top of the screw pipe 621 of the telescopic assembly 62 is connected to the bottom of the resisting block 61, forming a telescopic support structure.

The backing plate 623 is provided at the bottom of the adjusting screw 622, and the backing plate 623 contacts the bottom of the expansion joint, playing a role in support and stability. At the same time, it can reduce the stress on the top of the channel plate 1, ensuring the stability and safety of the overall structure. This design enables the support assembly 6 to have a greater adjustment range and applicability, suitable for dealing with situations of different heights, irregular terrains, or load requirements. At the same time, through this combined design, the stability and load-bearing capacity of the support system have been further improved.

[0030] In some preferred embodiments, a plurality of cross beams 3 are arranged along the longitudinal bridge direction of the channel plate 1, and the cross beams 3 are equally spaced along the transverse bridge direction of the channel plate 1; or, a plurality of cross beams 3 are arranged along the transverse bridge direction of the channel plate 1, and the cross beams 3 are equally spaced along the longitudinal bridge direction of the channel plate 1. The arrangement of the plurality of cross beams 3 can be selected according to specific requirements and site conditions to achieve the best support effect and structural stability. Specifically: First, a plurality of cross beams 3 are arranged along the longitudinal bridge direction of the channel plate 1: This arrangement can increase the stability and load-bearing capacity of the channel plate 1. By arranging a plurality of cross beams 3 along the longitudinal bridge direction of the channel plate 1, the load and supporting force can be effectively dispersed, reducing the deflection of the channel plate 1 and improving the overall stability of the structure; Second, a plurality of cross beams 3 are arranged along the transverse bridge direction of the channel plate 1. By arranging a plurality of cross beams 3 along the transverse bridge direction of the channel plate 1, the load on the channel plate in the transverse direction can be effectively supported. Both of these arrangement methods improve the load-bearing capacity and stability of the channel plate and are applicable to occasions where the load-bearing capacity and deflection control of the channel plate 1 in different directions need to be considered.

[0031] In some preferred embodiments, a connecting groove 11 is provided at the bottom of the channel plate 1; and a second abutting portion 12 is provided at the notch of the connecting groove 11; the abutting block 61 is fixedly arranged in the connecting groove 11 and abuts against the second abutting portion 12. Through the design of the connecting groove 11 and the second abutting portion 12, a reliable connection is formed between the bottom of the channel plate 1 and the abutting block 61, increasing the structural stability. The abutting block 61 is fixed in the connecting groove 11, which can effectively prevent the channel plate 1 from moving or deforming during use, ensuring the overall stability of the structure. In addition, since the abutting block 61 can be fixed in the connecting groove 11, if the channel plate 1 needs to be maintained or replaced, the abutting block 61 can be conveniently disassembled or replaced, reducing the difficulty and time cost of maintenance work. It should be noted that this design solution is different from the above. The connecting groove 11 is located at a fixed position at the bottom of the channel plate 1, and the support assembly 6 is fixedly connected thereto, and the position cannot be adjusted. Generally speaking, the design of the connecting groove 11 and the abutting block 61 can improve the stability and load-bearing capacity of the channel plate 1, and at the same time facilitate maintenance and management.

[0032] In some preferred embodiments, the connecting grooves 11 are arranged at equal intervals along the longitudinal length of the channel plate 1 and at equal intervals along the transverse length of the channel plate 1; the support assemblies 6 are respectively arranged in the corresponding connecting grooves 11. The advantages of this design are: uniform distribution. By arranging the connecting grooves 11 at equal intervals along the longitudinal and transverse lengths of the channel plate 1, the uniform distribution of the support assemblies 6 can be realized. This design can effectively disperse the load, improve the overall stability and load-bearing capacity of the channel plate 1. At the same time, it can also prevent the structure from deforming or being damaged due to excessive local load; flexibility. The equal interval arrangement of the connecting grooves 11 can make the position of the support assemblies 6 relatively flexible, facilitating adjustment and optimization according to specific usage requirements. Different positions of the support assemblies 6 can be selected according to the actual situation to achieve the best structural support effect; convenient maintenance. The support assemblies 6 can be easily installed in the corresponding connecting grooves 11, facilitating maintenance and replacement. At the same time, the equal interval arrangement of the connecting grooves 11 also facilitates the management and maintenance work, improving the maintainability and manageability of the overall system.

[0033] In some preferred embodiments, the longitudinal length of the channel plate 1 is greater than the distance between the longitudinal joints of the expansion joints; the transverse width of the channel plate 1 is equal to the transverse length of the expansion joints. It should be noted that this limitation on the channel plate 1 belongs to an actual application in specific embodiments, that is, the channel plate 1 completely covers the expansion joints of the entire T-beam, thus facilitating the safe reciprocating crossing of vehicles. In addition to meeting the needs of vehicle passage, this design can also effectively prevent sundries or other substances from falling into the expansion joints, ensuring the cleanliness and safety of the road. At the same time, it is also more convenient to maintain the channel plate 1, which can reduce the difficulty and risk of maintenance work.

[0034] In some preferred embodiments, the cross-bridge width of the channel plate 1 is less than the cross-bridge length of the expansion joint; a plurality of channel plates 1 are included, which are arranged at equal intervals along the cross-bridge direction of the expansion joint. This design can ensure that the channel plate 1 can be stably installed in the expansion joint while leaving the construction area of the expansion joint. The channel plates 1 are arranged at equal intervals along the cross-bridge direction of the expansion joint, which can better cover the entire expansion joint area and ensure that vehicles can pass safely. This setting method can not only effectively fill the expansion joint, reduce the falling of sundries, and improve the traffic safety, but also is conducive to maintaining the cleanliness and maintenance of the channel plate 1 and the expansion joint. The plurality of channel plates 1 are evenly distributed, and can also balance the load when the vehicle passes, reduce the impact force on the channel plate 1, and extend the service life.

[0036] The device includes a channel plate 1 installed at the expansion joint to ensure that vehicles can pass through the expansion joint smoothly. Longitudinal limit rods 5 are arranged on both sides of the channel plate 1 in the longitudinal-bridge direction, and these longitudinal limit rods 5 abut against the expansion joint wall, thereby restricting the offset of the channel plate 1 in the longitudinal-bridge direction and preventing it from falling off. Moreover, a support assembly 6 is connected to the bottom of the channel plate 1 to enhance the supporting force of the channel plate 1 and effectively prevent the channel plate 1 from collapsing, deforming or breaking.
