Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of bridge prefabricated components, specifically relating to a reinforced bridge steel structure prefabricated component. Background Technology
[0002] In the field of bridge engineering, the use of precast components has become a common and important construction method. Precast components can significantly improve construction efficiency, ensure project quality, and reduce the complexity and risks of on-site operations. However, due to the lack of effective support and load-distribution structural design, traditional bridge precast components are prone to displacement or tilting when subjected to external forces, resulting in insufficient overall bridge stability. Secondly, the limited connection methods between precast components make it difficult to flexibly adjust them according to different engineering needs, which to some extent limits the adaptability of bridge structures and the convenience of construction. Utility Model Content
[0003] Purpose of the utility model: To provide a reinforced prefabricated steel structure component for bridges, which solves the above-mentioned problems existing in the prior art.
[0004] Technical Solution: A reinforced precast steel structure for bridges includes a bridge frame body. A steel plate is vertically mounted on the center of the top surface of the bridge frame body. Mounting portions are formed on the top surface of the bridge frame body and the side of the steel plate. Limiting components are operatively mounted in the mounting portions on the bridge frame body and the steel plate, respectively. A telescopic component is installed between the limiting components. The telescopic component, the bridge frame body, and the steel plate form a triangular support. At least one set of support components is installed below the telescopic component. The other end of the support component is installed at the connection between the bridge frame body and the steel plate. A triangular support is formed between the support component, the telescopic component, the bridge frame body, and the steel plate.
[0005] Preferably, the mounting part includes a slide rail, which is located in the center of the bridge frame body or steel plate. The limiting component is slidably installed in the slide rail. Several limiting holes are respectively opened on both sides of the slide rail. The limiting component is partially inserted into the limiting holes, so that the telescopic component is installed at an angle between the bridge frame body and the steel plate, so that the bridge frame body, the steel plate and the telescopic component form a triangular support.
[0006] Preferably, the limiting component includes a movable plate, a limiting rod is installed on the side of the movable plate near the bridge frame body or steel plate, the limiting rod is operably inserted into the limiting hole, a movable block is slidably installed in the slide rail, a movable component is installed on the side of the movable block, and the movable end of the movable component is connected to the movable plate.
[0007] Preferably, the movable component includes a mounting block, which is mounted on the end of the movable block.

Detailed Implementation
[0014] like Figures 1 to 5 As shown, this utility model provides a technical solution: a reinforced precast steel structure for bridges, including a bridge frame body 1. A steel plate 2 is vertically installed on the center of the top surface of the bridge frame body. An installation part 3 is provided on the top surface of the bridge frame body and the side of the steel plate 2. Limiting components 4 are operably installed in the installation parts 3 on the bridge frame body and the steel plate 2 respectively. A telescopic component 5 is installed between the limiting components 4. The telescopic component 5, the bridge frame body, and the steel plate 2 form a triangular support. At least one set of support components 6 is installed below the telescopic component 5. The other end of the support component 6 is installed at the connection between the bridge frame body 1 and the steel plate 2. The support component 6, the telescopic component 5, the bridge frame body, and the steel plate 2 form a multi-branch triangular support structure, which can effectively distribute the load and improve the overall stability and load-bearing capacity of the bridge.
[0015] In a further embodiment, such as Figure 1As shown, the mounting part 3 includes a slide rail 31, which is located in the center of the bridge frame body 1 or steel plate 2. The limiting component 4 is slidably installed in the slide rail 31. Several limiting holes 32 are respectively opened on both sides of the slide rail 31. The limiting component 4 is partially inserted into the limiting holes 32, so that the telescopic component 5 is installed at an angle between the bridge frame body 1 and the steel plate 2, so that the bridge frame body 1, the steel plate 2 and the telescopic component 5 form multiple triangular supports. The limiting component 4 includes a movable plate 41. A limiting rod 42 is installed on the side of the movable plate 41 near the bridge frame body 1 or steel plate 2. The limiting rod 42 is operable to be inserted into the limiting holes 32. A movable block 43 is slidably installed in the slide rail 31. A movable component is installed on the side of the movable block 43. The movable component includes a mounting block. 44. The mounting block 44 is installed at the end of the movable block 43.

A push rod 47 is rotatably mounted at the other end of the rotating rod 46. The end of the push rod 47 is connected to the movable plate 41. Guide rods 48 are installed on both sides of the mounting block 44 through support blocks. The guide rods 48 pass through the movable plate 41. That is, when it is necessary to adjust the telescopic component 5, an external force is applied to the rotating handle 45 to drive the rotating handle 45 to rotate, thereby moving the movable plate 41 and the limiting rod 42, so that the limiting rod 42 moves from the limiting hole 32, thus adjusting the telescopic component 5. After the telescopic component 5 is adjusted, the movable plate 41 and the limiting rod 42 are moved by the moving parts, so that the limiting rod 42 is inserted into the limiting hole 32 to limit the telescopic component 5.
[0016] In a further embodiment, the telescopic component 5 includes a sleeve plate 51, which is rotatably mounted on the limiting component 4. The sleeve plate 51 is a hollow structure with one open end. A support component 6 is mounted on the side of the sleeve plate 51 near the bridge frame body 1. The support component 6 includes a lower universal joint 61 and an upper universal joint 62. Both the upper universal joint 62 and the lower universal joint 61 are cross universal joints. The lower universal joint 61 is mounted on the bridge frame body 1, and the upper universal joint 62 is mounted on the steel plate 2. A lead screw sleeve 63 is rotatably mounted on the other end of the lower universal joint 61. The lead screw sleeve 63 engages with a lead screw 64, and the other end of the lead screw 64 is mounted on the upper universal joint 62.

A plurality of insertion holes 52 are linearly arranged along the length of the sleeve plate 51, and the insertion holes 52 are connected to the hollow structure. Insertion plates 53 are inserted into the sleeve plate 51. The insertion plates 53 are rotatably mounted on the limiting component 4. The insertion plates 53 are linearly arranged along the length of the sleeve plate 53, and the receiving holes 54 correspond to the insertion holes 52. The sleeve plate 51 and the insertion plates 53 are connected and limited by a connector to the insertion holes 52 and the receiving holes 54. The connector can be bolts, but is not limited to bolts. That is, while adjusting the sleeve plate 51 and the insertion plates 53, the lead screw 64 and the lead screw sleeve 63 can be adjusted. This allows for flexible adjustment according to actual needs during the installation of the precast steel components of the bridge, improving the convenience and adaptability of construction.
