[0028] Embodiment 1, as Figure 1-4As shown, a steel frame bridge deck steel plate connection component includes a bracket 1 and a reinforcement frame 2, wherein the bottom of the bracket 1 is provided with the reinforcement frame 2, the upper surface of the bracket 1 is provided with a steel plate 3, the bottom of the steel plate 3 is provided with a fixing structure 4, and the surface of the reinforcement frame 2 is provided with a reinforcement structure 5. In the utility model, when using the steel frame bridge deck steel plate connection component, the reinforcement frame 2 can be placed on the ground first, and then the bracket 1 and the reinforcement frame 2 can be fixed and reinforced by the reinforcement structure 5 to achieve the effect of reinforcement and protection. At the same time, in order to avoid the existing steel frame bridge deck steel plate connection components, most of which directly weld the bridge steel plate to the bottom bracket 1, the steel bridge deck is under the long-term vehicle load, and the welding parts are under the combined influence of their own welding defects, that is, the external force, which is very easy to form fatigue cracks, seriously affecting the driving safety and easily causing the viaduct to collapse. The steel plate 3 and the bracket 1 can be fixed by the fixing structure 4, thereby completing the entire use.

[0029] Reference Figure 3 The fixing structure 4 includes a card block 401 and a fixing plate 402. The card block 401 is fixedly connected to the bottom of the steel plate 3. Card slots 409 are provided on the surfaces of the bracket 1 and the reinforcement frame 2. The card block 401 is slidably connected in the card slot 409. The surface of the card block 401 is fixedly connected to the fixing plate 402. The surface of the fixing plate 402 card block 401 is provided with a fixing slot 404. A sliding slot 403 is provided on the upper surface of the bracket 1. An adjusting rod 406 is slidably connected to the inner wall of the sliding slot 403. An installation slot 410 is provided at the bottom of the sliding slot 403. A fixing block 405 is slidably connected in the fixing slot 404. The top of the fixing block 405 is fixedly connected to the adjusting rod 406. A fixing spring 407 and a spring rod 408 are fixedly connected to the surface of the installation slot 410. The surface of the spring rod 408 is sleeved with a fixing spring 407. The fixing spring 407 and the spring rod 408 are fixedly connected to the fixing block 405 at one end away from the installation slot 410. In the utility model, by setting a fixing structure 4, when using the utility model, in order to avoid the existing steel frame bridge deck steel plate connecting components, most of the bridge steel plate and the bottom bracket 1 are directly welded. Under the long-term vehicle load, the welding parts of the steel bridge deck are very likely to form fatigue cracks under the combined influence of their own welding defects, that is, the external force, which seriously affects the driving safety and easily causes the viaduct to collapse. The steel plate 3 and the bracket 1 can be fixed by the fixing structure 4, and the adjusting rod 406 is first moved along the slide groove 403 in the direction away from the fixing groove 404, thereby driving the entire fixing block 405 to move out of the fixing groove 404. At this time, the steel plate 3 is clamped in the clamping groove 409 along the bottom clamping block 401. After the clamping is completed, the adjusting rod 406 is released, so that the fixing spring 407 inside the installation groove 410 drives the spring rod 408 to squeeze the fixing block 405 so that it is clamped in the fixing groove 404, thereby completing the entire fixation.

[0030] Reference Figure 4The reinforcement structure 5 includes a connection hole 501 and a U-shaped latch 502. The surfaces of the bracket 1 and the reinforcement frame 2 are both provided with connection holes 501. The U-shaped latch 502 is slidably inserted in the connection hole 501. The top of the U-shaped latch 502 is rotatably connected with a threaded rod 503. The surface of the threaded rod 503 is threadedly connected with a limit block 504. The surface of the limit block 504 is fixedly connected with a steel plate 3. In the utility model, by setting the reinforcement structure 5, when using the utility model, the reinforcement structure 5 is used to fix and reinforce the bracket 1 and the reinforcement frame 2 to achieve the effect of reinforcement and protection. The steel plate 3 is first clamped and fixed. At this time, the threaded rod 503 in the limit block 504 is rotated to drive the bottom U-shaped latch 502 to slide and insert in the connection hole 501, thereby achieving the effect of fixing the bracket 1 and the reinforcement frame 2.

[0031] Working principle: In the utility model, when using the steel frame bridge deck steel plate connecting component, the reinforcement frame 2 can be placed on the ground first, and then the reinforcement structure 5 can be used to fix and reinforce the bracket 1 and the reinforcement frame 2 to achieve the effect of reinforced protection. The steel plate 3 is first clamped and fixed, and then the threaded rod 503 in the rotating limit block 504 drives the bottom U-shaped pin 502 to slide and be inserted into the connecting hole 501, thereby achieving the effect of fixing the bracket 1 and the reinforcement frame 2. At the same time, in order to avoid the existing steel frame bridge deck steel plate connecting components, most of the bridge steel plates are directly welded to the bottom bracket 1. Under the action of long-term vehicle loads, the welding parts of the steel bridge deck are damaged by their own welding defects, i.e., external forces. Under the combined influence of the effects, fatigue cracks are easily formed, which seriously affect driving safety and easily cause the collapse of the viaduct. The steel plate 3 and the bracket 1 can be fixed by the fixing structure 4. First, the adjusting rod 406 is moved along the slide groove 403 in the direction away from the fixing groove 404, thereby driving the entire fixing block 405 to move out of the fixing groove 404. At this time, the steel plate 3 is clamped in the clamping groove 409 along the bottom clamping block 401. After the clamping is completed, the adjusting rod 406 is released, so that the fixing spring 407 inside the installation groove 410 drives the spring rod 408 to squeeze the fixing block 405 to make it clamped in the fixing groove 404, thereby completing the entire fixation, thereby completing the entire use.
