[0028] Specifically, the limiting spring 35 is arranged on the outer arc surface of the limiting rod 33, and the number of the limiting spring 35 is two, and the two limiting springs 35 are arranged symmetrically left and right at the center of the fixed block 34.

[0029] The above-mentioned components achieve the effect that the linkage block 36 is facilitated to be applied with a reset elastic force through the limiting spring 35.

[0030] Specifically, the clamping block 37 is clamped with the inner wall of the limiting groove 31, the side of the clamping block 37 away from the linkage block 36 is arranged in an inverted angle, the number of the clamping block 37 is two, and the two clamping blocks 37 are arranged symmetrically left and right at the axis of the limiting rod 33.

[0031] The above-mentioned components achieve the effect that the position of the prefabricated bridge deck 2 is facilitated to be limited through the clamping block 37, so that the U-shaped beam 1 and the prefabricated bridge deck 2 can be quickly connected.

[0032] Specifically, the pushing block 39 is in contact with the inner wall of the linkage groove 38, and the number of the pushing block 39 is two, and the two pushing blocks 39 are arranged symmetrically left and right at the axis of the limiting rod 33.

[0033] The above-mentioned components achieve the effect that the position of the linkage block 36 is facilitated to be moved through the pushing block 39, so that the prefabricated bridge deck 2 can be quickly unlocked.

[0034] Specifically, the lower surface of the prefabricated bridge deck 2 is provided with a guide assembly 4, the guide assembly 4 comprises a guide groove 41, the upper surface of the U-shaped beam 1 is provided with the guide groove 41, the lower surface of the prefabricated bridge deck 2 is fixedly connected with a guide column 42, the lower surface of the U-shaped beam 1 is fixedly connected with a constraint plate 43, the inner part of the constraint plate 43 is slidably connected with a sliding block 44, one side of the sliding block 44 is fixedly connected with a connecting rod 45, and the lower surface of the constraint plate 43 is fixedly connected with a guide cylinder 46.

[0035] The above-mentioned components achieve the effect that the two sliding blocks 44 are facilitated to be connected through the connecting rod 45, so that the guide column 42 can be smoothly inserted into the sliding block 44.

[0036] Specifically, the surface of the sliding block 44 is provided with a through hole, the upper surface of the sliding block 44 is provided with a chamfer, and the number of the sliding block 44 is two. The two sliding blocks 44 are symmetrically arranged at the axis of the connecting rod 45.

[0037] The effect achieved by the above component is that the chamfered upper surface of the sliding block 44 can facilitate the insertion of the guide column 42 into the guide cylinder 46 for guiding.

[0040] Working principle: when the U-shaped beam 1 and the prefabricated bridge deck 2 need to be connected, the worker only needs to pick up the prefabricated bridge deck 2, align the limiting groove 31 with the linkage block 36, and then press down the prefabricated bridge deck 2. The prefabricated bridge deck 2 moves downward under stress, moves in cooperation with the chamfer of the clamping block 37, and then the prefabricated bridge deck 2 extrudes the clamping block 37. The clamping block 37 cooperates with the linkage block 36, extrudes the limiting spring 35, and the limiting spring 35 is deformed under stress. The linkage block 36 and the clamping block 37 are driven to move toward the fixed block 34 until the prefabricated bridge deck 2 successfully contacts the U-shaped beam 1. Then the clamping block 37 loses pressure, the linkage block 36 releases the pressure of the limiting spring 35, and then the limiting spring 35 rebounds to push the linkage block 36, so that the clamping block 37 enters the limiting groove 31. Subsequently, the position of the prefabricated bridge deck 2 can be limited; when the prefabricated bridge deck 2 needs to be removed, the worker only needs to hold the push block 39 with both hands, and then pull the push block 39 to move toward the fixed block 34. The linkage block 36 moves while extruding the limiting spring 35, the limiting spring 35 is deformed under stress, and then the clamping block 37 is driven to move toward the fixed block 34. The clamping block 37 moves until it loses the limitation on the prefabricated bridge deck 2, and then another worker can take down the prefabricated bridge deck 2. By arranging the assembly component 3, the U-shaped beam 1 and the prefabricated bridge deck 2 can be effectively spliced without various complicated procedures and long time consumption, which greatly reduces the waiting time of each link and further improves the construction efficiency.

[0041] In addition, by setting the guide assembly 4, it is not ensured that the prefabricated bridge plate 2 can be more stably aligned with the clamping block 37 during installation. After the worker picks up the prefabricated bridge plate 2, the guide column 42 can be aligned with the sliding block 44 first. After the guide column 42 is inserted into the sliding block 44, the prefabricated bridge plate 2 can be slid immediately. The prefabricated bridge plate 2 drives the sliding block 44 to move. During the movement of the sliding block 44, when the guide column 42 coincides with the guide cylinder 46, the guide column 42 will lose the restriction of the limiting plate 43, that is, it can be inserted into the guide cylinder 46. Then the limiting groove 31 can directly abut against the clamping block 37 on both sides, so that it can be directly installed. By setting the guide assembly 4, the position of the limiting groove 31 and the clamping block 37 can be effectively determined, and the workers do not need to align and install one by one, which further effectively improves the installation efficiency of the prefabricated bridge plate 2.
