Description

Technical Field

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

[0002] Currently, when transporting large haulage items, external factors such as increased traffic loads cause bridges to become unsuitable for such transport. Therefore, bridge reinforcement is necessary to prevent traffic disruptions. However, traditional reinforcement methods in bridge construction and maintenance often face challenges such as high construction complexity, difficulty, and cost. These methods typically require large quantities of building materials, leading to extended construction periods and significantly increased resource consumption. These factors make traditional reinforcement methods unsuitable for large-scale transportation activities that require rapid completion. They not only fail to effectively reduce construction costs but also increase operation and maintenance costs. Therefore, a bridge reinforcement structure for road reconstruction is proposed to meet these requirements.

[0003] However, existing bridge reinforcement structures have certain defects. They cannot provide reliable rigid support for bridges, thus failing to guarantee the bridge's resistance to deformation and load-bearing capacity. Furthermore, they cannot quickly carry out the pouring operation of reinforcement structures, which seriously affects the installation efficiency of bridge reinforcement structures. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This utility model provides a bridge reinforcement structure for road reconstruction, such as... Figures 1 to 4 As shown, the structure includes: a steel arch 1, connectors 2, and reinforcement components. The steel arch 1 is used for supporting the bridge reinforcement structure. The steel arch 1 consists of main steel sections and multiple ribs. Connectors 2 are connected to the steel arch 1. Connectors 2 can be connecting plates with threaded holes. Bolts are threaded into the threaded holes to connect the bridge. The reinforcement components include carbon fiber strips 3, carbon fiber sheets 4, supports 5, and connecting rods 6. The carbon fiber strips 3 are bonded to the steel arch 1 and to the top of the ribs. Carbon fiber fabric sheet 4 is bonded to carbon fiber fabric strip 3. Carbon fiber fabric sheet 4 is bonded to the bottom of the bridge using epoxy resin-based structural adhesive. The angle between carbon fiber fabric strip 3 and carbon fiber fabric sheet 4 is 90°. The carbon fiber fabric strip 3 and carbon fiber fabric strip 4 work together to form a mesh support structure. Support member 5 is connected to the steel arch 1. Connecting rod 6 is movably mounted on support member 5. Support member 5 can be a support plate. Two support members 5 are fixedly connected to each rib. The steel arch 1 uses carbon fiber fabric strip 3 to keep the carbon fiber fabric sheet 4 in contact with the external bridge structure. Multiple fiber strips 3 are evenly spaced on the steel arch 1. The carbon fiber strips 3 are located above the steel arch 1. The support member 5 has a movable groove 10, and the connecting rod 6 is movably disposed in the movable groove 10. It also includes a casting assembly, which includes a casting chamber 7, a limiting member 8, and a sealing ring 9. The support member 5 is inserted into the casting chamber 7. There are two casting chambers 7, located at the bottom of both ends of the steel arch 1. The limiting member 8 is connected to the casting chamber 7 and can be a limiting plate, keeping it in close contact with the outermost support member 5. The support member 5 remains in contact with the limiting member 8, the connecting rod 6 is movably set in the pouring chamber 7, and the sealing ring 9 is sleeved on the connecting rod 6. The sealing ring 9 is made of silicone to prevent some concrete from overflowing from the gap between the connecting rod 6 and the pouring chamber 7 when pouring. The sealing ring 9 remains in close contact with the pouring chamber 7. There are two limiting members 8 on the pouring chamber 7, and the two limiting members 8 are located at both ends of the pouring chamber 7. There are two sealing rings 9 on the connecting rod 6, and the two sealing rings 9 are located at both ends of the pouring chamber 7.

[0024] By combining reinforcement components, the bridge can be provided with rigid support, and the carbon fiber mesh structure can disperse local stress. The two work together to significantly improve the bridge's resistance to deformation and load-bearing capacity. It can also quickly realize the pouring operation of the reinforcement structure, thereby improving the installation efficiency of the equipment.

[0025] In use, when reinforcing an arch bridge, firstly, multiple carbon fiber fabric sheets 4 are equidistantly bonded laterally to the bottom of the bridge (using epoxy resin-based structural adhesive). Next, multiple carbon fiber fabric strips 3 are equidistantly bonded longitudinally to the steel arch 1 (located at the top of multiple ribs of the steel arch 1). Then, the steel arch 1 is moved, causing the support member 5 to be inserted into the casting chamber 7. The outer surface of the limiting member 8 contacts the outermost support member 5 to limit the movement of the steel arch 1. Then, the connecting rod 6 is removed, first passing through one end of the casting chamber 7, then through multiple support members 5, and finally exiting from the other end of the casting chamber 7, thus achieving the connection between the steel arch 1 and the casting chamber 7. The steel arch 1 is moved to the bottom of the bridge. Then, two casting chambers 7 are buried at the bottom of both ends of the bridge. The bolts are then removed and tightened to connect the steel arch 1 to the bridge. At this time, the carbon fiber strips 3 are tightly attached to the bottom of the carbon fiber sheet 4. Since the angle between the carbon fiber sheet 4 and the carbon fiber strips 3 is 90°, a mesh support structure is formed to transfer the bridge load to the steel arch 1, thereby enhancing the overall compressive and load-bearing capacity. Concrete is then poured into the casting chamber 7 to provide stable support for the steel arch 1. Since the connecting rod 6 is fitted with sealing rings 9 on the outer surface of the casting chamber 7 at both ends, it can effectively prevent concrete from leaking from the gaps during pouring.

[0026] Specifically, multiple connectors 2 are fixedly connected to the outer surface of the steel arch 1, multiple carbon fiber strips 3 are bonded to the top of the steel arch 1, and carbon fiber sheets 4 are bonded to the top of the carbon fiber strips 3. Multiple support members 5 are fixedly connected to the bottom of both ends of the steel arch 1. Each support member 5 has a movable groove 10 inside, and a connecting rod 6 is movably connected inside the movable groove 10. The support member 5 is inserted into the inside of the casting chamber 7, and the outer surface of the connecting rod 6 is movably connected to the inside of the casting chamber 7. Limiting members 8 are fixedly connected to the inside of both ends of the casting chamber 7. One end face of the limiting member 8 is kept in contact with the support member 5. Sealing rings 9 are sleeved on both ends of the connecting rod 6, and the two sealing rings 9 are kept in contact with the outer surfaces of both ends of the casting chamber 7.

[0027] Working Principle: In actual use, when reinforcing an arch bridge, this device firstly bonds multiple carbon fiber cloth sheets 4 equidistantly laterally to the bottom of the bridge (using epoxy resin-based structural adhesive). Next, it bonds multiple carbon fiber cloth strips 3 equidistantly longitudinally to the steel arch 1 (located at the top of multiple ribs of the steel arch 1). Then, it moves the steel arch 1, causing the support member 5 to be inserted into the casting chamber 7. The outer surface of the limiting member 8 contacts the outermost support member 5 to limit the movement of the steel arch 1. Then, the connecting rod 6 is removed, first passing through one end of the casting chamber 7, then through multiple support members 5, and finally exiting from the other end of the casting chamber 7, thus connecting the steel arch 1 and the casting chamber 7. Next, the steel arch 1 is moved to the bottom of the bridge, and then two casting chambers 7 are respectively embedded at the bottom of both ends of the bridge. Then, the bolts are removed and tightened to connect the steel arch 1 to the bridge. At this time, the carbon fiber strip 3 is tightly attached to the bottom of the carbon fiber sheet 4. Since the angle between the carbon fiber sheet 4 and the carbon fiber strip 3 is 90°, a mesh support structure is formed, which transfers the bridge load to the steel arch 1 and enhances the overall compressive and load-bearing capacity. Then, concrete is poured into the casting chamber 7 to provide stable support for the steel arch 1. Since the two ends of the connecting rod 6 are fitted with sealing rings 9 on the outer surface of the casting chamber 7, it can effectively prevent concrete from leaking from the gaps during pouring and can provide reliable rigid support for the bridge. The carbon fiber mesh structure can disperse local stress. The two work together to significantly improve the bridge's resistance to deformation and load-bearing capacity, and can also quickly realize the pouring operation of the reinforcement structure, thereby improving the installation efficiency of the equipment.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
