Description

Technical Field

[0001] This utility model relates to the field of structural reinforcement technology, and in particular to a structure for reinforcing bridges. Background Technology

[0002] In recent years, with the rapid development of urban construction and the continuous expansion of transportation networks, long-span bridges have played an important role in complex terrain and have become a key component of modern transportation infrastructure. However, due to their large span and complex stress, long-span bridges have more stringent requirements for reinforcement technology, and traditional bridge reinforcement structures are no longer able to meet the maintenance needs of such bridges.

[0003] Existing bridge reinforcement structures have many limitations, especially when dealing with the reinforcement of long-span bridges. Most traditional reinforcement devices can only strengthen local structures and cannot form an effective overall support system, resulting in a small reinforcement span, which is difficult to meet the stress requirements of long-span bridges under heavy traffic.

[0004] Therefore, given the numerous limitations of existing bridge reinforcement devices, a bridge reinforcement structure can be designed. This structure, which uses multiple sets of first and second mounting plates in conjunction with reinforcement struts, effectively connects the bridge deck and connecting plate, forming a stable triangular support system. This significantly increases the reinforcement span, thereby facilitating the solution of the aforementioned problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing bridge reinforcement structures, which can only strengthen local structures and cannot form an effective overall support system, resulting in a small reinforcement span and difficulty in meeting the stress requirements of large-span bridges under heavy traffic, this utility model provides a structure for reinforcing bridges.

[0006] The technical solution is as follows: A bridge reinforcement structure includes a beam-pier reinforcement mechanism, a beam-pier connection mechanism, a long-span bridge reinforcement mechanism, a square bottom pier, a cylindrical top pier, and a bridge slab; the beam-pier reinforcement mechanism includes two sets of arc-shaped clamps, with a corresponding cylindrical top pier between the two sets of arc-shaped clamps; the lower end of the cylindrical top pier has a square bottom pier for connecting with the bridge pier foundation, and the upper end of the cylindrical top pier has a bridge slab; a fixing groove for fixing the lower section of the cylindrical top pier is opened between the two sets of arc-shaped clamps; a semi-circular fixing plate is provided at the outer bottom of each set of arc-shaped clamps; the surface of the square bottom pier has a beam-pier connection mechanism connected to the beam-pier reinforcement mechanism; the beam-pier connection mechanism includes a connecting plate, and both sides of the surface of the connecting plate have long-span bridge reinforcement mechanisms for reinforcing the bridge slab.

[0007] Furthermore, both sets of arc-shaped clamps have a semi-circular fixing plate at the bottom of their outer ends, and multiple sets of triangular reinforcing ribs are evenly arranged at the outer ends of both sets of arc-shaped clamps. The bottom of the multiple sets of triangular reinforcing ribs extends to the surface of the semi-circular fixing plate. Both ends of both sets of arc-shaped clamps have splicing plates, and multiple sets of splicing holes are opened on the surface of the splicing plates.

[0008] Furthermore, multiple sets of positioning holes are evenly opened on the surface of the semi-circular fixing plate. These positioning holes are staggered along the multiple sets of triangular reinforcing ribs. Each of the positioning holes is equipped with a fastening steel bar. The upper end of the fastening steel bar is equipped with a limiting block, and the lower end of the fastening steel bar extends into the interior of the square base through the positioning hole.

[0009] Furthermore, each of the two sets of semi-circular fixed plates has a movable groove on its outer edge, and movable holes are provided on both sides of the movable groove. Multiple sets of connecting buckles corresponding to the movable groove are arranged around the outer ends of the two sets of semi-circular fixed plates. The rear end of the connecting buckle is provided with a movable shaft, and both ends of the movable shaft extend into the interior of the movable hole.

[0010] Furthermore, the connecting plate is attached to the surface of the square base, and the center of the connecting plate has a connecting port to accommodate two sets of semi-circular fixing discs. Multiple sets of buckle grooves are formed around the edge of the connecting port, and the buckle grooves have buckle seats corresponding to the connecting port inside.

[0011] Furthermore, the long-span bridge reinforcement mechanism includes multiple sets of first mounting plates and multiple sets of second mounting plates. The multiple sets of first mounting plates are evenly arranged along the linear edge on both sides of the surface of the connecting plate, and the multiple sets of second mounting plates are evenly distributed along the linear edge on both sides of the bottom of the bridge plate. A first movable connecting seat is installed at the upper end of the first mounting plate, and a second movable connecting seat is installed at the lower end of the second mounting plate. Adjustment holes are opened inside both the first and second movable connecting seats.

[0012] Furthermore, a reinforcing strut is provided between the first mounting plate and the second mounting plate, and both ends of the reinforcing strut are provided with adjusting shafts, with both ends of the adjusting shafts extending into the interior of the adjusting holes.

[0013] The beneficial effects are as follows: First, by using multiple sets of first and second mounting plates in conjunction with the reinforcing struts, a multi-point support and stable triangular support system is formed, effectively increasing the reinforcement span and better meeting the stress requirements of long-span bridges under heavy traffic. Second, the synergistic effect of components such as the arc-shaped clamps, triangular reinforcing bars, semi-circular fixing discs, and fastening steel bars in the beam-pier reinforcement mechanism enhances the reinforcement effect on the beam-pier and the overall structural strength. Third, the close connection between the beam-pier connection mechanism and the beam-pier reinforcement mechanism and the long-span bridge reinforcement mechanism ensures the effective transfer and distribution of loads, improving the stability and reliability of the entire bridge reinforcement structure. Fourth, the structural design of the connecting buckles, movable grooves, movable shafts, buckle slots, and buckle seats facilitates the installation and disassembly of various components, reducing construction difficulty and maintenance costs.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figures 1-4 As shown, a bridge reinforcement structure includes a beam-pier reinforcement mechanism 1, a beam-pier connection mechanism 2, a long-span bridge reinforcement mechanism 3, a square bottom pier 4, a cylindrical upper pier 5, and a bridge deck 6. The beam-pier reinforcement mechanism 1 includes two sets of arc-shaped clamps 101, with a corresponding cylindrical upper pier 5 between the two sets of arc-shaped clamps 101. The lower end of the cylindrical upper pier 5 is provided with a square bottom pier 4 for connection with the bridge pier foundation, and the upper end of the cylindrical upper pier 5 is provided with a bridge deck 6. A fixing groove 103 for fixing the lower section of the cylindrical upper pier 5 is opened between the two sets of arc-shaped clamps 101. The bottom outer ends of both sets of arc-shaped clamps 101 are provided with semi-circular fixing plates 102. The surface of the square bottom pier 4 is provided with a beam-pier connection mechanism 2 connected to the beam-pier reinforcement mechanism 1. The beam-pier connection mechanism 2 includes a connecting plate 201, and both sides of the surface of the connecting plate 201 are provided with long-span bridge reinforcement mechanisms 3 for reinforcing the bridge deck 6.

[0022] Both sets of arc-shaped clamps 101 have semi-circular fixing plates 102 at their outer bottom ends. Multiple sets of triangular reinforcing ribs 106 are evenly distributed at the outer ends of both sets of arc-shaped clamps 101, with the bottoms of the triangular reinforcing ribs 106 extending to the surface of the semi-circular fixing plates 102. Both ends of both sets of arc-shaped clamps 101 have splicing plates 104, with multiple splicing holes 105 on their surface. The semi-circular fixing plates 102 provide a stable bottom support foundation for the arc-shaped clamps 101, enhancing the connection stability between the arc-shaped clamps 101 and the underlying structure. The evenly distributed triangular reinforcing ribs 106 extending to the surface of the semi-circular fixing plates 102 effectively enhance the overall structural strength of the arc-shaped clamps 101 using the principle of triangular stability, making them less prone to deformation and damage when subjected to large external forces. The splicing plates 104 and splicing holes 105 facilitate the splicing and installation between the two sets of arc-shaped clamps 101.

[0023] Multiple sets of positioning holes 107 are evenly provided on the surface of the semicircular fixing plate 102. The multiple sets of positioning holes 107 are staggered between multiple sets of triangular reinforcing ribs 106. Each set of positioning holes 107 is provided with a fastening steel bar 108. The upper end of the fastening steel bar 108 is provided with a limiting block 109. The lower end of the fastening steel bar 108 extends into the interior of the square base 4 through the positioning hole 107. The positioning hole 107 provides a precise installation position for the fastening steel bar 108, ensuring a more stable and reliable connection between the semicircular fixing plate 102 and the square base 4. The fastening steel bar 108 extends into the interior of the square base 4 through the positioning hole 107, realizing a deep connection between the semicircular fixing plate 102 and the square base 4, effectively transmitting and dispersing the stress on the upper structure, improving the load-bearing capacity of the entire reinforced structure, and the limiting block 109 prevents the fastening steel bar 108 from falling off.

[0024] Both sets of semicircular fixing plates 102 have movable grooves 110 on their outer edges. Movable holes 111 are provided on both sides of the movable grooves 110. Multiple sets of connecting buckles 112 corresponding to the movable grooves 110 are arranged around the outer ends of the two sets of semicircular fixing plates 102. Movable shafts 113 are provided at the rear ends of the connecting buckles 112. Both ends of the movable shafts 113 extend into the interior of the movable holes 111. Through the cooperative design of the connecting buckles 112, the movable grooves 110, and the movable shafts 113, the quick connection and separation of the two sets of semicircular fixing plates 102 and the connecting plate 201 are realized.

[0025] The connecting plate 201 is attached to the surface of the square base 4. The center of the connecting plate 201 has a connecting port 202 to accommodate two sets of semi-circular fixing discs 102. Multiple sets of buckle grooves 203 are formed around the edge of the connecting port 202. The buckle grooves 203 have buckle seats 204 corresponding to the connecting port 202 inside. The design of the connecting port 202 makes it easy to accommodate two sets of semi-circular fixing discs 102. The buckle grooves 203 and buckle seats 204, together with the connecting buckle 112 and the movable shaft 113, further enhance the connection strength between the connecting plate 201 and the semi-circular fixing discs 102, preventing loosening or displacement during the stress process.

[0026] The long-span bridge reinforcement mechanism 3 includes multiple sets of first mounting plates 301 and multiple sets of second mounting plates 303. The first mounting plates 301 are evenly arranged linearly along both sides of the surface of the connecting plate 201, and the second mounting plates 303 are evenly distributed linearly along both sides of the bottom of the bridge deck 6. A first movable connecting seat 302 is mounted on the upper end of each first mounting plate 301, and a second movable connecting seat 304 is mounted on the lower end of each second mounting plate 303. Both the first movable connecting seat 302 and the second movable connecting seat 304 have adjustment holes inside. The first mounting plate 301 and the second mounting plate 303 are evenly arranged on both sides of the bottom of the connecting plate 201 and the bridge plate 6, respectively, which can provide multiple stable mounting points for the reinforcing strut 305, forming a multi-point support system. This effectively increases the reinforcement span and improves the reinforcement effect on long-span bridges. Through the setting of the first movable connecting seat 302 and the second movable connecting seat 304, as well as the design of the internal adjustment hole, the connection between the reinforcing strut 305 and the mounting plate has a certain degree of flexibility and can be adjusted to a certain extent according to the actual span.

[0027] A reinforcing strut 305 is installed between the first mounting plate 301 and the second mounting plate 303. Each end of the reinforcing strut 305 is equipped with an adjusting shaft 306, which extends into the interior of the adjusting hole. The reinforcing strut 305 is installed between the first mounting plate 301 and the second mounting plate 303, forming a stable triangular support system. This effectively enhances the connection strength between the bridge deck 6 and the connecting plate 201, and improves the stability of the entire bridge structure.

[0028] During operation, the connecting plate 201 is first attached to the surface of the square base pier 4. Then, pre-drilled holes for fastening the reinforcing bars 108 are made on the surface of the square base pier 4. Next, the cylindrical upper pier 5 is hoisted to the upper center of the square base pier 4. At this time, the bottom of the cylindrical upper pier 5 is located at the center of the connecting port 202. Then, two sets of arc-shaped clamps 101 hold the bottom of the cylindrical upper pier 5. At this time, two sets of semi-circular fixing plates 102 are located inside the connecting port 202. Then, the bolts are passed through the splicing holes 105 of the splicing plate 104 to splice and fix it. The connecting buckle 112 is moved so that it rotates along the movable hole 111 through the movable shaft 113. The front end of the connecting buckle 112 is engaged with the buckle slot 203 and fixed with the buckle seat 204.

[0029] Then, the reinforcing strut 305 is installed between the first mounting plate 301 and the second mounting plate 303, so that the adjusting shafts 306 at both ends of the reinforcing strut 305 extend into the adjusting holes. After adjusting the position of the second mounting plate 303 according to the actual span, it is welded to ensure the formation of a stable triangular support system.

[0030] Its working principle is as follows: During the use of the bridge, loads such as vehicles act on the bridge deck 6. The load on the bridge deck 6 is transmitted through the large-span bridge reinforcement mechanism 3. The triangular support system formed by the reinforcement strut 305, the first mounting plate 301, and the second mounting plate 303 utilizes the principle of triangular stability to evenly distribute the load to the connecting plate 201 and the beam pier reinforcement mechanism 1. The arc-shaped clamp 101 in the beam pier reinforcement mechanism 1 enhances its own structural strength through the triangular reinforcing rib 106. The semi-circular fixing plate 102 is tightly connected to the square bottom pier 4 through the fastening steel bar 108, so that the load can be effectively transferred to the bridge pier foundation, thereby achieving reinforcement and support for the entire bridge structure. At the same time, the design of the adjustment holes and adjustment shaft 306 inside the first movable connecting seat 302 and the second movable connecting seat 304 makes it easy to adjust the angle of the reinforcement strut 305 according to the span of the bridge deck 6.

[0031] Its beneficial effects are significant. Compared with traditional bridge reinforcement structures, this utility model uses multiple sets of first mounting plates 301 and second mounting plates 303 to reinforce the struts 305, forming a multi-point support and stable triangular support system, which effectively increases the reinforcement span and can better meet the stress requirements of large-span bridges under heavy traffic. Secondly, the synergistic effect of components such as the arc-shaped clamp 101, triangular reinforcing ribs 106, semi-circular fixing discs 102, and fastening steel bars 108 in the beam-pier reinforcement mechanism 1 enhances the reinforcement effect on the beam-pier and the overall structural strength. Thirdly, the beam-pier connection mechanism 2 is closely connected with the beam-pier reinforcement mechanism 1 and the large-span bridge reinforcement mechanism 3, ensuring the effective transfer and distribution of loads and improving the stability and reliability of the entire bridge reinforcement structure. Fourthly, the structural design of the connecting buckle 112, movable groove 110, movable shaft 113, buckle groove 203, buckle seat 204, etc., facilitates the installation and disassembly of various components, reducing construction difficulty and maintenance costs.
