Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to a reinforcement structure for bridge railings. Background Technology

[0002] The main types of bridges include arch bridges, suspension bridges, and rigid frame bridges. Depending on the local geology and the span of the bridge, corresponding types of bridges are built on rivers, lakes, or seas to facilitate the passage of vehicles or pedestrians and make transportation more convenient and efficient.

[0003] Due to regional differences, some coastal cities have high air humidity. When bridges are affected by typhoons and heavy rains, bridge railings may corrode or become loose. When pedestrians lean on them, the railings may bend or break, creating safety hazards. In such cases, regular maintenance of bridge railings is necessary. However, damaged railings are not easy to remove and replace, resulting in a lot of time required for disassembly and reassembly. When maintaining long bridges, in order to ensure construction and road safety, it is often necessary to partition sections of the bridge, which narrows the lanes or roads, causing traffic congestion and travel inconvenience.

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0027] like Figure 1-4 As shown, a reinforcement structure for a bridge railing includes:

[0028] The column 1 has an installation groove 11, and a connecting rod 2 and a support rod 3 are respectively installed in the installation groove 11;

[0029] The clamping rod 12 is disposed in the mounting groove 11 and is respectively engaged with the connecting rod 2 and the support rod 3;

[0030] The protective rod 41 is mounted on the column 1. One end of the protective rod 41 is rotatably equipped with a rotating sleeve 43. The rotating sleeve 43 is threadedly connected to a locking rod 44 that engages with the column 1. The rotating sleeve 43 rotates to control the locking rod 44 to extend or retract within the protective rod 41.

[0031] Specifically, column 1 is fixed to the concrete of the bridge with expansion bolts. The installation of the guardrail is completed by installing connecting rod 2, handrail 3 and guardrail 41. When a crossbeam is worn or damaged, column 1 and connecting rod 2 can be removed by loosening clamping rod 12. The guardrail 41 can be rotated by rotating sleeve 43, so that clamping rod 44 retracts into the guardrail 41 and detaches from column 1. At this time, the guardrail 41 is in a disassembled state, and the guardrail 41 or its parts can be maintained or replaced. The rotating sleeve 43 is located on the guardrail 41 and can be removed. Furthermore, connecting rod 2 supports two adjacent columns 1, and handrail 3 provides support for the column 1 for pedestrians to hold on to. Clamping rod 12 can be bolts or round columns with interference fit.

[0032] As a further embodiment of this utility model, a groove 411 is provided on the protective rod 41, and bent rods 42 are arranged in a linear array within the groove 411. The linear array is configured such that multiple sets of bent rods 42 are arranged sequentially along the direction of the protective rod 41. The protective rod 41 and the bent rods 42 are assembled to form a support frame 4. A first locking member 412 that fits against the groove 411 is provided on the bent rod 42. Multiple bent rods 42 can be provided on the protective rod 41, and the spacing between the multiple bent rods 42 is consistent. The spacing between adjacent bent rods 42 is less than 15cm. After the position of the bent rods 42 is determined, they can be fixed by the first locking members 412 at both ends.

[0033] As a further embodiment of this utility model, a groove 421 is provided on the bent rod 42, and a support rod 422 is slidably disposed in the groove 421. One end of the support rod 422 is engaged with a rubber sleeve 423. A sleeve post 427 is rotatably disposed on the bent rod 42, and a telescopic rod 425 is slidably disposed on the sleeve post 427. A rotating seat 424 that cooperates with the support rod 422 is provided on the telescopic rod 425. Before a typhoon or storm, the support rod 422 can be moved out of the groove 411, so that the rubber sleeve 423 at one end of the support rod 422 is in contact with the concrete surface (e.g., Figure 4 As shown), during the sliding of the support rod 422, the sleeve post 427 rotates on the bent rod 42. Under the traction of the rotating seat 424, the telescopic rod 425 extends from the sleeve post 427 and forms a triangular stable structure with the support rod 422, thereby improving the stability of the railing. Furthermore, when it rains, the bent rod 42 can be moved closer to the post 1 for support, thereby improving the support effect on the post 1. At the same time, multiple guard rods 41 need to be installed, and at least four (e.g., Figure 4 As shown, the protective rod 41 in the middle part is in contact with the bent rod 42.

[0034] As a further embodiment of this utility model, the bent rod 42 is provided with a third locking member 428 that cooperates with the support rod 422. When the rubber sleeve 423 on the support rod 422 comes into contact with the concrete, it can be fixed by the third locking member 428. At the same time, the third locking member 428 plays a guiding role, so that the support rod 422 can only slide along the slide groove 411. When the support rod 422 slides to the end, the third locking member 428 can be set to rotate between them.

[0035] As a further embodiment of this utility model, a second locking member 426 is provided on the sleeve post 427. The second locking member 426 cooperates with the telescopic rod 425. After the sliding distance of the telescopic rod 425 on the sleeve post 427 is determined, it can be locked by the second locking member 426.

[0036] As a further embodiment of this utility model, a bracket 14 is provided on the column 1, and an installation hole is provided on the bracket 14. The clamping rod 44 is engaged in the installation hole. A water outlet groove 141 is provided on the bracket 14. The bracket 14 is welded to the column 1, which improves the stability of the column 1. In rainy weather, rainwater will flow out from the water outlet groove, thereby preventing rainwater from accumulating on the bracket 14.

[0037] As a further embodiment of this utility model, a protective plate 13 is provided on one side of the column 1 to block the installation hole. The protective plate 13 has the effect of blocking and reducing rainwater from entering the bracket 14. The protective plate 13 is snapped onto the column 1.

[0038] As a further embodiment provided in this utility model, a rubber ring 16 that cooperates with the clamping rod 44 is snapped into the mounting hole. The rubber ring 16 improves the support and sealing effect between the protective rod 41 and the column 1.

[0039] As a further embodiment of this utility model, a guide block 161 is provided on the rubber ring 16, and a stop block 17 that cooperates with the guide block 161 is provided on the clamping rod 44. The stop block 17 is circular with a notch and hollow in the center. When the protective rod 41 is installed on the column 1, the stop block 17 can be clamped onto the clamping column to protect the clamping column. The guide block 161 keeps the notch facing downwards.

[0040] As a further embodiment of this utility model, a baffle 18 and an inclined plate 15 are respectively provided on the column 1. The inclined plate 15 is engaged with the baffle 18. One end of the inclined plate 15 is in contact with the concrete and is fixed by expansion bolts, while the other end is engaged with the baffle 18, so that the vertical cut sections of the baffle 18 and the inclined plate 15 are triangular, thereby improving the support effect on the column 1.

[0041] Working principle: When the handrail 3, connecting rod 2, or guardrail 41 is worn or damaged, the clamping rod 12 can be removed from the mounting groove 11 of the handrail 3 and connecting rod 2 to loosen them for disassembly. When the guardrail 41 or parts on the guardrail are damaged, the rotating sleeves 43 at both ends of the guardrail 41 can be rotated to retract the locking rod 44 into the guardrail 41, separating the guardrail 41 from the post 1. The rotating sleeves 43 can be struck to separate them from the guardrail 41, allowing the guardrail 41 or parts on the guardrail 41 to be interchanged, improving the efficiency of disassembly and assembly. In contrast, the crossbeams of traditional railings are often welded, and after damage, they can be replaced by cutting and welding. The railing of this application saves maintenance time and improves the efficiency of disassembly and assembly.

[0042] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0043] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
