Description

Technical Field

[0001] This utility model relates to the field of bridge pier reinforcement technology, specifically a bridge pier anti-overturning reinforcement structure. Background Technology

[0002] Currently, single-column pier bridges are widely used in municipal and highway bridges due to their advantages such as small footprint, low construction cost, and aesthetically pleasing appearance. However, single-column piers typically have a single support for the superstructure beam in the transverse direction, resulting in insufficient lateral restraint on the main beam and a risk of support failure and lateral overturning.

[0003] Existing anti-overturning reinforcement schemes for single-column pier bridges involve adding new columns next to the original piers to support the main beams, thereby improving the anti-overturning performance of the main beams. However, adding new columns increases the land area occupied, seriously affecting the original road traffic and the clearance of the lower level of the bridge. Therefore, an anti-overturning reinforcement structure for bridge piers is proposed. Utility Model Content

[0011] Furthermore, the ear plates are connected by bolts, with several bolts located on the ear plates. The bolts and nuts are matched to achieve a tight connection between the left outer semicircular plate and the right outer semicircular plate.

[0012] Furthermore, both the left and right outer semicircular plates are provided with reinforcing ribs on their outer walls, and the column is provided with several guide slopes.

[0013] Furthermore, the anti-tipping support includes a base, which is located on top of the reinforcing rib plate, and the outer wall of the base is provided with several clamping plates, and a hollow column is provided at the top center of the base.

[0014] Furthermore, a spring is provided on the inner wall of the hollow column, a limit post is provided on the top of the spring, a top seat is provided on the top of the limit post, and a spring shock absorber is provided between the top seat and the base.

Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-7 As shown, this utility model provides a technical solution: a bridge pier anti-overturning reinforcement structure, including a column 1. The overall diameter of the column 1 is not constant. The diameter of the lower part of the column 1 is larger than that of the upper part. The radius difference between the lower and upper parts can just accommodate the left inner semicircular plate 309, the right inner semicircular plate 311 and the interlocking plate 307, so that after the three are installed, the column 1 looks like the upper and lower dimensions are consistent. From top to bottom, there are a main beam 101, a main support seat 102 and the column 1. The fixing component 3 is set on the outer wall of the column 1 to provide support for the anti-overturning support seat 2. The anti-overturning support seat 2 is set on the left and right sides of the top of the column 1 to provide auxiliary support for the main beam 101.

[0029] like Figure 1-7 As shown in the embodiment of this application, the fixing component 3 includes a U-shaped plate 310, which is disposed on the upper outer wall of the column 1. Several U-shaped plates 310 are disposed and arranged in a circumferential array around the outer wall of the column 1. The U-shaped plates 310 are adapted to the interlocking plates 307, which are respectively located on the inner walls of the left inner semicircular plate 309 and the right inner semicircular plate 311, and their number is equal to that of the U-shaped plates 310. Specifically, the U-shaped plates 310 are fixedly connected to the upper outer wall of the column 1, and the inner wall of the U-shaped plates 310 has a accommodating space equal to that of the interlocking plates 309 and 307. The size is 7. Therefore, the interlocking plate 307 is adapted to the U-shaped plate 310. The U-shaped plates 310 are arranged in a circular array around the column 1. The distance between two adjacent U-shaped plates 310 on the left and right is equal to the length of the interlocking plate 307, and the distance between two adjacent U-shaped plates 310 on the top and bottom is equal to the height of the interlocking plate 307. When installing the left inner semicircular plate 309 and the right inner semicircular plate 311, first, align the gaps between the interlocking plate 307 and the U-shaped plate 310 of the left inner semicircular plate 309. At this time, the top of the left inner semicircular plate 309 should be... The distance above the top of column 1 is equal to the height of one U-shaped plate 310, while the distance between the top of column 1 and the bottom of main beam 101 is much greater than the height of one U-shaped plate 310. The left inner semicircular plate 309 has grooves that match the protrusions at both ends of the right inner semicircular plate 311. The initial connection is achieved through the cooperation of the protrusions and grooves. At this point, the interlocking plates 307 on the inner walls of the left inner semicircular plate 309 and the right inner semicircular plate 311 are located at the cross intersection formed by the gap between the U-shaped plates 310. Rotating the left and right inner circular plates counterclockwise or clockwise, until the ear plates 303 at both ends... When the column 1 is positioned at the center of the front and rear sides, the left inner semicircular plate 309 and the right inner semicircular plate 311 are moved downwards. Then, the interlocking plate 307 will be embedded into the inner wall of the U-shaped plate 310 and form a mechanical interlock with it. At this time, the outer ring of the top of the column 1 will support the left inner semicircular plate 309 and the right inner semicircular plate 311, and the U-shaped plate 310 will also limit them, realizing the connection between the two and the column 1. The interlocking plate 307 is fixedly connected to the left inner semicircular plate 309 and the right inner semicircular plate 311 respectively. At this point, the initial installation of the outer sleeve of the column 1 is completed.

[0030] like Figure 1-7As shown in the embodiment of this application, a left outer semicircular plate 308 is provided on the outer wall of the left inner semicircular plate 309, and a right outer semicircular plate 301 is provided on the outer wall of the right inner semicircular plate 301. Ear plates 303 are provided on the outer walls of both ends of the left outer semicircular plate 308 and the right outer semicircular plate 301. The ear plates 303 are connected by bolts 306. Several bolts 306 are provided on the ear plates 303, and the bolts 306 are matched with nuts 305 to achieve a tight connection between the left outer semicircular plate 308 and the right outer semicircular plate 301. Specifically, the left inner semicircular plate 309 and the left outer semicircular plate 308 are fixedly connected, while the right inner semicircular plate 301... The semicircular plate 311 and the right outer semicircular plate 301 are also fixedly connected. Therefore, after completing the connection between the left inner semicircular plate 309 and the right inner semicircular plate 311, the connection between the left outer semicircular plate 308 and the right outer semicircular plate 301 and the column 1 is also realized. The ear plates 303 at both ends of the left outer semicircular plate 308 and the right outer semicircular plate 301 will be aligned with each other. The bolts 306 are used to pass through the ear plates 303 and are tightened with nuts 305, so that the left and right semicircular plates are tightly fitted. Thus, the sleeve can be installed without drilling the column 1. The sleeve here refers to the left and right semicircular plates.

[0031] like Figure 1-7 As shown, both the left outer semicircular plate 308 and the right outer semicircular plate 301 are provided with reinforcing ribs 304 on their outer walls, and the column 1 is provided with several guide slopes 302. Specifically, after the left and right semicircular plates are installed, reinforcing ribs 304 are welded to their outer walls to enhance circumferential stiffness. The top of the reinforcing ribs 304 extends to the bottom of the anti-tipping support seat 2 to form a vertical support transmission path. The guide slopes 302 are opened on the column 1 and are connected to the vertical gap formed between them and the U-shaped plate 310 to prevent rainwater from accumulating inside the left and right semicircular plates and causing corrosion.

[0032] like Figure 1-7As shown in the embodiment of this application, the anti-tipping support 2 includes a base 203, which is located on top of the reinforcing rib 304. Several retaining plates 201 are provided on the outer wall of the base 203. A hollow column 204 is provided at the top center of the base 203. A spring 205 is provided on the inner wall of the hollow column 204. A limiting post 207 is provided at the top of the spring 205. A top seat 206 is provided at the top of the limiting post 207. A spring damper 202 is provided between the top seat 206 and the base 203. Specifically, several spring dampers 202 are provided at one end of the top seat 206 corresponding to the base 203. A limiting post 207 is fixedly provided in the middle of the bottom of the top seat 206, while a hollow column 204 is fixedly provided in the middle of the top of the base 203. The base 203 is installed on the top left and right sides of the reinforcing rib 304. The locking blocks around the base 203 are fixedly connected to the reinforcing rib 304 to limit the installation position of the base 203. The spring shock absorbers 202 are arranged in a ring array between the top seat 206 and the base 203. With the cooperation of the anti-overturning support seat 2 and the main support seat 102, a three-support seat form is formed for the main beam 101, which increases the anti-overturning performance and solves the problem of the small anti-overturning stability coefficient of a single independent column 1. In addition, the spring shock absorbers 202 between the top seat 206 and the base 203 are used for buffering and shock absorption, which further improves the stability of the column 1. Since the spring shock absorber 202 is existing technology, its working principle will not be described in detail here.

[0033] The working principle of this utility model is as follows:

[0034] The top outer wall of column 1 is provided with U-shaped plates 310 arranged in a circumferential array. Using interlocking plates 307, the interlocking plates 307 on the left inner semicircular plate 309 are placed at the cross-shaped interface formed by the gaps between the U-shaped plates 310. Then, the grooves at both ends of the left inner semicircular plate 309 and the protrusions at both ends of the right inner semicircular plate 311 are engaged to realize the installation between the left inner semicircular plate 309 and the right inner semicircular plate 311, thereby realizing the installation between the left outer semicircular plate 308 and the right outer semicircular plate 301. Afterwards, bolts 306 are used to pass through the ear plate 303 and engage with nuts 305 to achieve a tight connection between the left and right semicircular plates without drilling to damage the structure of column 1. Then, the anti-tipping support 2 is installed in the clamping plates 201 on both sides of the top of the reinforcing rib plate 304. Afterwards, the outer walls of the left outer semicircular plate 308 and the right outer semicircular plate 301 are... Welded reinforcing ribs 304 enhance the circumferential stiffness of the left and right semicircular plates. The top of the reinforcing ribs 304 extends to the bottom of the anti-tipping support 2, forming a vertical support transmission path. This allows the load of the anti-tipping support 2 to be evenly transmitted, avoiding local stress concentration. Subsequently, the main support 102 at the top of the column 1 and the anti-tipping support 2 form a three-support system, which can distribute the eccentric load of the main beam 101 from a single support to multiple support points, increasing the anti-overturning moment. The top seat 206 provides reverse support force through the dual elastic action of the spring damper 202 and the spring 205, offsetting part of the overturning moment. Furthermore, the guide slope 302 on the column 1 can drain rainwater from the connection of the fixing components 3 along the slope, preventing rainwater from accumulating in the gap between the semicircular plate and the column 1, reducing the corrosion of the steel structure by water vapor, and extending the service life of the reinforced structure.

[0035] In summary, this utility model discloses a bridge pier anti-overturning reinforcement structure, including a column 1, and from top to bottom, a main beam 101, a main support seat 102 and the column 1 are arranged in sequence. A fixing component 3 is arranged on the outer wall of the column 1 to provide support for the anti-overturning support seat 2. The anti-overturning support seat 2 is arranged on the left and right sides of the top of the column 1 to provide auxiliary support for the main beam 101. This invention utilizes the mechanical interlocking of the U-shaped plate 310 and the interlocking plate 307 to achieve an initial connection between the left and right semicircular plates. Subsequently, the bolts 306 and nuts 305 work together to achieve a tight connection between the left and right semicircular plates and the column 1. This eliminates the need for drilling or pouring concrete, thus protecting the integrity of the original column 1 structure. Furthermore, the fixing component 3 and the anti-tipping support 2 work together to form a rigid force transmission path. Off-center loads can be transmitted to the column 1 using the reinforcing ribs 304, improving overall rigidity. The combination of the spring 205 and the spring damper 202 can automatically adjust the rigidity according to the load size, balancing elastic support and energy-dissipating buffer, thereby improving the practicality of the device.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
