Description

Technical Field

[0001] This utility model relates to the field of bridge steel structure reinforcement, and in particular to a bridge steel structure reinforcement device. Background Technology

[0002] A bridge is a structure built to cross natural or man-made obstacles, spanning rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, substructure, and ancillary structures. The superstructure mainly refers to the span structure and bearing system; the substructure includes abutments, piers, and foundations. Piers support the abutments. Due to the limited bearing area at the top of the piers, stress is concentrated within a limited area, resulting in relatively poor overall load-bearing capacity. Therefore, additional steel structures are needed to reinforce the load-bearing capacity.

[0003] In the process of anti-overturning reinforcement of bridge steel structures, if the reinforcement device cannot dynamically adjust the support angle according to the degree of overturning, the reinforcement effect may be unsatisfactory. If the angle of the reinforcement support is fixed, it cannot adapt to the changes in the degree of overturning caused by load changes, foundation settlement or external environment in actual use of the bridge. This will result in uneven distribution of support force or local stress concentration, which not only reduces the adaptability of the reinforcement device, but may also make the bridge still have the risk of overturning in extreme cases.

[0004] Therefore, in the process of anti-overturning reinforcement of bridge steel structures, if the reinforcement device cannot dynamically adjust the support angle according to the degree of overturning, the reinforcement effect may be unsatisfactory. If the angle of the reinforcement support is fixed, it cannot adapt to the changes in the degree of overturning caused by load changes, foundation settlement or external environment in actual use of the bridge, thus reducing the adaptability of the reinforcement device. Therefore, bridge steel structure reinforcement devices can be designed and adjustable anti-overturning reinforcement devices can be installed. Utility Model Content

[0005] In order to overcome the problem that if the reinforcement device cannot dynamically adjust the support angle according to the degree of overturning during the anti-overturning reinforcement of bridge steel structures, the reinforcement effect may be unsatisfactory, reducing the adaptability of the reinforcement device.

[0006] The technical solution of this utility model is as follows: a bridge steel structure reinforcement device, including a bridge column, a threaded rod, a rotating block, and a reinforcement block. Two reinforcement frames are movably connected to the outer surface of the bridge column. A reinforcement block is provided on the side of the reinforcement frame away from the bridge column. A slot is opened at the bottom of the reinforcement block. Two threaded rods are fixedly connected to the top of the reinforcement frame corresponding to the slot. The threaded rods are slidably connected to the reinforcement block. Two rotating blocks are rotatably connected to the bottom of the reinforcement block corresponding to the threaded rods. The rotating blocks are threadedly connected to the threaded rods. A limit block is fixedly connected to the side of the reinforcement frame away from the bridge column. The limit block is slidably connected to the reinforcement block.

[0007] Preferably, when dynamic adjustment of the installation is required according to the degree of overturning, the rotating block is rotated so that it rotates on the threaded rod, causing the reinforcing block to move upward. At the same time, the threaded rod slides in the slot, and the limiting block restricts the movement of the reinforcing block on the reinforcing frame, thereby making a more precise adjustment of the height of the reinforcing block.

[0008] Preferably, the top of the bridge column is fixedly connected to a support base, the top of the reinforcing block is fixedly connected to the same support base, the top of the support base is fixedly connected to a spring damper, and the top of the spring damper is fixedly connected to a support top.

[0009] Preferably, the bottom of the support top is fixedly connected to the outer plate two, the top of the support bottom is fixedly connected to the outer plate two, and the outer plate one and the outer plate two are slidably connected.

[0010] Preferably, connecting plates are fixedly connected to the left and right sides of the bridge column, and a support column is provided on the top of the connecting plates.

[0011] Preferably, support plates are fixedly connected to the upper and lower sides of the support column, and bolts are threaded inside the support plates.

[0012] Preferably, bolt one is threadedly connected to the connecting plate and bolt one is threadedly connected to the reinforcing frame.

[0013] As a preferred embodiment, the internal threaded connection of the reinforcing frame includes two bolts, which are threadedly connected to the bridge column.

[0014] The beneficial effects of this utility model are:

[0015] When dynamic adjustment of the installation is required based on the degree of overturning, rotating the rotating block causes it to rotate on the threaded rod, which in turn moves the reinforcing block upward. At the same time, the threaded rod slides in the slot, and the limiting block restricts the movement of the reinforcing block on the reinforcing frame. This allows for more precise adjustment of the height of the reinforcing block, solving the problem that if the reinforcing device cannot dynamically adjust the support angle according to the degree of overturning during the anti-overturning reinforcement of bridge steel structures, the reinforcement effect may be unsatisfactory, reducing the adaptability of the reinforcing device.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment: a bridge steel structure reinforcement device includes a bridge column 1, threaded rods 4, rotating blocks 5, and reinforcement blocks 6. Two reinforcement frames 2 are movably connected to the outer surface of the bridge column 1. A reinforcement block 6 is provided on the side of the reinforcement frame 2 away from the bridge column 1. A slot 3 is formed at the bottom of the reinforcement block 6. Two threaded rods 4 are fixedly connected to the top of the reinforcement frame 2 corresponding to the slot 3, and the threaded rods 4 are slidably connected to the reinforcement block 6. Two rotating blocks 5 are rotatably connected to the bottom of the reinforcement block 6 corresponding to the threaded rods 4, and the rotating blocks 5 are threadedly connected to the threaded rods 4. The reinforcement frame 2 is located away from the bridge column 1. A limiting block 7 is fixedly connected on one side, and the limiting block 7 is slidably connected to the reinforcing block 6. When it is necessary to dynamically adjust the installation according to the degree of overturning, the rotating block 5 is rotated to make it rotate on the threaded rod 4, which drives the reinforcing block 6 to move upward. At the same time, the threaded rod 4 slides in the slot 3. The limiting block 7 restricts the movement position of the reinforcing block 6 on the reinforcing frame 2, thereby making more precise adjustments to the height of the reinforcing block 6. This solves the problem that if the reinforcing device cannot dynamically adjust the support angle according to the degree of overturning during the anti-overturning reinforcement of bridge steel structures, the reinforcement effect may be unsatisfactory, reducing the adaptability of the reinforcing device.

[0023] Please see Figures 2-4 In this embodiment, the top of the bridge column 1 is fixedly connected to the support base 8, the top of the reinforcing block 6 is fixedly connected to the same support base 8, the top of the support base 8 is fixedly connected to the spring damper 9, the top of the spring damper 9 is fixedly connected to the support top 17, the support top 17 is fixedly connected to the bridge, the spring damper 9 between the support top 17 and the support base 8 increases the seismic resistance in the event of an earthquake, the bottom of the support top 17 is fixedly connected to the outer plate 2 11, the top of the support base 8 is fixedly connected to the outer plate 2 11, the outer plate 1 10 and the outer plate 2 11 are slidably connected, and the outer plate 2 11 and the outer plate 10 are precisely slidably connected to prevent external dust from entering.

[0024] Please see Figures 2-4In this embodiment, connecting plates 12 are fixedly connected to the left and right sides of the bridge column 1, and a support column 13 is provided on the top of the connecting plate 12. The support column 13 and the connecting plate 12 provide support for the reinforcement frame 2. Support plates 14 are fixedly connected to the upper and lower sides of the support column 13, and bolts 15 are threadedly connected to the inside of the support plate 14. The connecting plate 12 is fixed to the connecting plate 12 and the reinforcement frame 2 by bolts 15. Bolts 15 are threadedly connected to the connecting plate 12 and to the reinforcement frame 2. The reinforcement frame 2 is fixed to the bridge column 1 by bolts 26. Bolts 26 are threadedly connected to the inside of the reinforcement frame 2 and to the bridge column 1. The reinforcement frame 2 is fixed to the bridge column 1 by bolts 26.

[0025] During operation, the reinforcing frame 2 is fixed to the bridge column 1 with bolt 2 16. Then, the connecting plate 12 is fixed to the connecting plate 12 and the reinforcing frame 2 with bolt 15. The support column 13 and the connecting plate 12 provide support for the reinforcing frame 2. The support top 17 is fixedly connected to the bridge. The spring damper 9 between the support top 17 and the support bottom 8 increases the seismic resistance in the event of an earthquake. The outer plate 2 11 and the outer plate 10 are precisely slidably connected to prevent external dust from entering. When it is necessary to dynamically adjust the installation according to the degree of overturning, the rotating block 5 is rotated so that it rotates on the threaded rod 4 to drive the reinforcing block 6 to move upward. At the same time, the threaded rod 4 slides in the slot 3. The limiting block 7 restricts the movement position of the reinforcing block 6 on the reinforcing frame 2, thereby making a more precise adjustment of the height of the reinforcing block 6.

[0026] Through the above steps, the spring damper 9 between the top 17 and the bottom 8 of the support increases the seismic resistance under conditions such as earthquakes. The outer plate 2 11 and the outer plate 1 10 are precisely slidably connected to prevent external dust from entering. When it is necessary to dynamically adjust the installation according to the degree of overturning, the rotating block 5 is rotated to make it rotate on the threaded rod 4, which drives the reinforcing block 6 to move upward. At the same time, the threaded rod 4 slides in the slot 3. The limiting block 7 restricts the movement position of the reinforcing block 6 on the reinforcing frame 2, thereby making a more precise adjustment of the height of the reinforcing block 6. This solves the problem that if the reinforcing device cannot dynamically adjust the support angle according to the degree of overturning during the anti-overturning reinforcement of bridge steel structures, the reinforcement effect may be unsatisfactory. If the angle of the reinforcement support is fixed, it cannot adapt to the changes in the degree of overturning caused by load changes, foundation settlement or external environment in actual use of the bridge, thus reducing the adaptability of the reinforcement device.
