Description

Technical Field

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

[0002] Bridges are typically built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. With the continuous increase in urban traffic load, bridge structures, especially at bridge joints, are prone to stress concentration, local deformation, and fatigue damage under long-term loads. This usually leads to a decrease in bridge stability and, in severe cases, may cause the bridge structure to fail. It is necessary to regularly inspect bridge joints and reinforce any bridge joints with potential hazards.

[0003] Existing bridge joint reinforcement methods involve adding steel bars, bolts, or other supporting structures to strengthen the joints. These methods are mostly simple reinforcements, and in the long term, they still face problems such as local stress concentration and fatigue damage at the joints. Moreover, the direction of force on bridge joints is not fixed or singular during use. In particular, at the splicing points of bridge structures, there will be various stress conditions such as linear stress, bending force, and shear force. A single joint reinforcement structure is difficult to adapt to the specific needs of different bridge joints. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a bridge node reinforcement structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bridge joint reinforcement structure includes a reinforcement base, wherein a web reinforcement mechanism is provided at the middle position of the reinforcement base, and both sides of the web reinforcement mechanism are connected to the bridge body.

[0007] The top of the web reinforcement mechanism is provided with a reinforcing connecting plate that cooperates with it. Several frame support structures are provided between the reinforcing connecting plate and the web reinforcement mechanism. Support torsion frames are provided at both ends of the frame support structures. The support torsion frames are connected to the web reinforcement mechanism.

[0008] Furthermore, the web reinforcement mechanism includes symmetrically distributed mounting plates, with symmetrically arranged extended support plates at the top of the mounting plates, and reinforcing steel on one side of the extended support plates, the reinforcing steel being installed inside the bridge body.

[0009] Furthermore, the mounting plate is a U-shaped structure, with the vertical sides of the U-shaped structure symmetrically installed on the bridge body, and the included angle of the vertical side axis of the U-shaped structure includes 0°, 60° and 90°.

[0010] Furthermore, the bottom of the extended support plate and both sides of the reinforcing connecting plate are provided with arc blocks that cooperate with the bridge body, and the arc of the arc blocks is greater than 10° and less than 30°.

[0011] The reinforcing connecting plate has an arc-shaped groove that matches the arc block.

[0012] Furthermore, the frame support structure includes a support frame, on which a plurality of evenly distributed frame grooves are provided, and a support rod is provided inside the frame groove, and a connecting groove is provided in the middle of the support rod.

[0013] Furthermore, a combination plate is provided on one side of the support frame, the combination plate is connected to the support rod by bolts, and the combination plate is provided with several sliding connecting blocks.

[0014] Furthermore, the support torsion frame is fixedly connected to the support rod by bolts. The support torsion frame includes a rectangular frame and a mating frame. The rectangular frame connects both the support frame and the combined plate. The mating frame is connected to both the support frame and the rectangular frame.

[0015] Furthermore, the mounting frame is an L-shaped structure, and bolts are provided at the corners of the L-shaped structure to connect it to the support frame. Restricting blocks are provided at both ends of the L-shaped structure.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: By coordinating the web-joint reinforcement mechanism, the strengthening connecting plate, and the frame support structure, the stress transmission path of the bridge node is optimized, effectively avoiding stress concentration caused by uneven stress. By extending the support plate and reinforcing steel, the contact depth between the reinforcement structure and the bridge body is extended, which can evenly distribute the stress in the local stress area to a larger range. In addition, the arc design reduces stress concentration caused by bending force, improving the shear and bending resistance of the node. Furthermore, by adjusting the stress through the mounting plate, the shear and bending resistance is enhanced, while adapting to different bridge nodes, avoiding local deformation, and improving the overall structural stability. This provides long-term durability and fatigue resistance of the node, thereby reducing structural damage caused by fatigue and extending the service life of the bridge. Attached Figure Description

[0026] Reference Figure 1-5 The bridge node reinforcement structure is connected and installed with the bridge body;

[0027] A bridge joint reinforcement structure includes a reinforcement base 1, a web reinforcement mechanism 2 is provided in the middle of the reinforcement base 1, and the two sides of the web reinforcement mechanism 2 are connected to the bridge body. The reinforcement base 1 is installed at the connection between the bridge body and the support pier.

[0028] The top of the bracing reinforcement mechanism 2 is provided with a reinforcing connecting plate 3 that cooperates with it. Several modular frame support structures 4 are provided between the reinforcing connecting plate 3 and the bracing reinforcement mechanism 2. Support torsion frames 16 are provided at both ends of the frame support structures 4, and the support torsion frames 16 are connected to the bracing reinforcement mechanism 2.

[0029] The stress concentration area is dispersed by the web reinforcement mechanism 2, and the stress transmission is optimized by the reinforcing connecting plate 3 and the frame support structure 4. The reinforcement seat 1 is used to tightly connect the web reinforcement mechanism 2 to the bridge body to ensure uniform stress transmission at the node. In addition, the frame support structure 4 is modularly connected and designed to enhance the stability of the overall structure. At the same time, the installation method can be adjusted according to the actual reinforcement situation to carry out targeted reinforcement installation, so as to avoid stress concentration and local deformation at the bridge node, which can lead to fatigue damage to the structure.

[0030] In a specific embodiment of this application, the web reinforcement mechanism 2 includes symmetrically distributed mounting plates 5. The top of the mounting plates 5 is symmetrically provided with extended support plates 6. One side of the extended support plate 6 is provided with reinforcing steel 7. The reinforcing steel 7 is installed inside the bridge body. By installing the reinforcing steel 7 inside the bridge body, the force is transferred to a larger range in the stress area through the extended support plate 6, avoiding local stress concentration. Furthermore, because the reinforcing steel 7 penetrates deep into the bridge body, it can improve the shear and bending resistance of the joint, improve the stress distribution in the joint area, thereby reducing deformation and fatigue damage at the joint and enhancing the stability of the joint.

[0031] Reference Figure 1-5 In a specific embodiment of this application, the mounting plate 5 is a U-shaped structure. The vertical sides of the U-shaped structure are symmetrically installed on the bridge body, and the included angles of the vertical side axes of the U-shaped structure include 0°, 60°, and 90°. The U-shaped design of the mounting plate 5 makes the connection between the mounting plate 5 and the bridge body tighter, and the included angle of the vertical side can be adjusted during installation to adapt to different stress states of the bridge nodes. In addition, the U-shaped structure can provide greater shear and bending resistance. The angle design makes the stress distribution of the structure more reasonable and prevents local instability of the nodes.

[0032] Reference Figure 1-5 In a specific embodiment of this application, the bottom of the extended support plate 6 and both sides of the reinforcing connecting plate 3 are provided with arc blocks 8 that cooperate with the bridge body. The arc curvature of the arc block 8 is greater than 10° and less than 30°.

[0033] The reinforcing connecting plate 3 has an arc-shaped groove 9 that matches the arc block 8.

[0034] The curved block 8 and the curved groove 9 can change the direction of force transmission in the bridge body and the supporting structure. By designing the curvature of the curved block 8 to be greater than 10° and less than 30°, the stress state of the node can be better adjusted. When the bridge body generates bending force, a smooth transition can be achieved, avoiding the stress concentration problem caused by straight connection, improving the uniformity of force distribution, and increasing the reinforcement effect.

[0035] Reference Figure 1-5In a specific embodiment of this application, the frame support structure 4 includes a support frame 10, on which a plurality of evenly distributed frame grooves 11 are provided, and a support rod 12 is provided inside the frame groove 11, and a connecting groove 13 is provided in the middle position of the support rod 12.

[0036] The frame support structure 4 forms a support system through the support frame 10 and the support rod 12. The connecting groove 13 of the support rod 12 can be easily connected to other support structures. Moreover, due to the modular installation design of the frame support structure 4, different sides of multiple frame support structures 4 can be connected and fixed. That is, multiple frame support structures 4 can be connected with different other structures. By adjusting the main connection points and stress points, local deformation can be avoided during the reinforcement process, and targeted adjustments can be made to enhance the support strength.

[0037] Reference Figure 1-5 In a specific embodiment of this application, a combination plate 14 is provided on one side of the support frame 10. The combination plate 14 is connected to the support rod 12 by bolts. The combination plate 14 is provided with a plurality of sliding connection blocks 15. The combination plate 14 provides an extended installation structure for the support frame 10 and allows for fine-tuning during construction. At the same time, the connection rigidity can be reduced by the sliding connection, thereby compensating for minor deviations caused by installation errors or material deformation, ensuring structural stability, and providing adjustment space for construction.

[0038] The supporting torsion frame 16 is fixedly connected to the supporting rod 12 by bolts. The supporting torsion frame 16 includes a rectangular frame 17 and a mating frame 18. The rectangular frame 17 connects both the supporting frame 10 and the combined plate 14. The mating frame 18 is connected to the supporting frame 10 and the rectangular frame 17. The mating frame 18 has an L-shaped structure, and bolts are installed at the corners of the L-shaped structure to connect to the supporting frame 10. Restricting blocks 19 are provided at both ends of the L-shaped structure. It is not difficult to see from the above design that the supporting torsion frame 16 is installed at both ends of the supporting frame 10 to provide fixed support force for both ends of the supporting frame 10. The rectangular frame 17 provides the main support connection and connects and reinforces the supporting frame 10 and the combined plate 14. The additional mating frame 18 structure increases the connection points while avoiding excessive displacement and loosening between components. It can also use the allowable displacement distance to support and transfer the force, so that the bridge maintains good stability and stiffness when under stress.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
