Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a snap-on bridge-crossing pipe box reinforcement bracket. Background Technology
[0002] In highway bridges, underpass duct boxes are important infrastructure that are exposed to the natural environment for a long time. Over time, they are at risk of aging, weathering, and even falling off, posing a safety hazard to pedestrians and surrounding property. In existing technologies, triangular brackets are usually used to support the underpass duct boxes. However, these brackets only provide support and cannot effectively anchor the duct boxes. Moreover, the installation work requires climbing over the guardrails to work under the duct boxes, which poses a significant safety risk. In addition, the cost of replacing the entire underpass duct box is high, and the construction location is not conducive to operation, further increasing the construction difficulty and risk. Therefore, a snap-on underpass duct box reinforcement bracket is needed to solve the above technical problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] In existing technologies, triangular brackets are typically used to support the overhead pipe boxes. However, these brackets only provide support and cannot effectively anchor the pipe boxes. Furthermore, the installation work requires climbing over guardrails to work under the pipe boxes, which poses a significant safety risk.
[0021] To address the aforementioned defects in the fixing process of the bridge duct box, please refer to [link / reference needed]. Figures 1-4 This utility model provides a snap-on bridge-crossing pipe box reinforcement bracket, which eliminates the need for construction outside the crash barrier, reducing road closures and construction safety risks. The reinforcement bracket uses a one-piece molded steel support 1 as its foundation. The steel support 1 is S-shaped and consists of a C-shaped mounting part 11 and an L-shaped reinforcement part 12 for supporting the bridge-crossing pipe box. The end of the mounting part 11 furthest from the reinforcement part 12 is bent outwards, and the bending angle of the mounting part 11 matches the shape of the crash barrier. The mounting part 11 can be snapped onto the crash barrier. Three sets of fixing members 2 are provided on three sides of the mounting part 11 to secure it to the crash barrier. These three sets of fixing members 2 fix the mounting part 11 from different positions, forming a three-point fixation, which increases the installation efficiency. The installation part 11 is stable on the crash barrier to prevent it from loosening or falling off. The installation part 11 and the reinforcement part 12 are integrally formed, which also ensures the stability of the reinforcement part 12. The height of the reinforcement part 12 is higher than that of the bridge duct box, and the bridge duct box passes through the reinforcement part 12. The reinforcement part 12 can provide sufficient support for the bridge duct box, thereby firmly fixing the bridge duct box to the crash barrier. Moreover, the installation of the steel bar bracket 1 does not require climbing over the crash barrier. Construction personnel can complete all operations on the bridge surface, reducing safety risks. The entire installation process is simple, which can effectively shorten the construction period and reduce the impact on traffic.
[0022] As the main supporting structure, the steel reinforcement support 1 needs to be made of high-strength materials. Therefore, the steel reinforcement support 1 uses galvanized steel bars, and the diameter of the steel reinforcement support 1 is set to 25mm. The outer surface of the steel reinforcement support 1 is coated with anti-rust paint. The 25mm diameter galvanized steel bars have high tensile and compressive strength, which can withstand large loads and ensure the stability of the support in harsh environments. In extreme cases such as typhoons and earthquakes, the steel reinforcement support 1 is not easily deformed or broken, effectively preventing the bridge duct box from falling off. The anti-rust paint provides good anti-corrosion protection for the steel bars, resisting the erosion of rainwater, moisture and chemicals, extending the service life of the support, reducing maintenance frequency and costs, and is particularly suitable for high-speed bridges that are exposed to the outdoor environment for a long time.
[0023] To achieve the fixing effect of the fastener 2 on the mounting part 11, the fastener 2 is designed as a sleeve 21 that slides outside the steel bar support 1. Both ends of the sleeve 21 are provided with fixing plates 22, and at least two fastening bolts 23 are installed on the fixing plates 22. The fixing plates 22 can be fixed to the crash barrier by the fastening bolts 23. The position of the fixing plates 22 can be adjusted by sliding the sleeve 21. Since the crash barrier is a cement barrier, its surface has pits and unevenness and poor flatness. The fixing plates 22 are designed to be movable, so that the fixing plates 22 can be adjusted to a relatively flat position and then fixed by the fastening bolts 23. This can ensure the fixing effect of the fixing plates 22. Then the sleeve 21 can be fixed to the crash barrier, which can realize the installation of the steel bar support 1.
[0024] After adjusting the fixing plate 22 to the appropriate position, the sleeve 21 needs to be fixed to the mounting part 11. This ensures the stability of the connection between the mounting part 11 and the sleeve 21. The side of the sleeve 21 is threaded with mounting bolts 24. The outer surface of the mounting part 11 has multiple threaded holes 111 for mounting bolts 24. After sliding the sleeve 21 to the designated position, rotate the mounting bolts 24 to connect the sleeve 21 and the mounting part 11. Then fix the fixing plate 22 to enhance the stability of the mounting part 11 on the crash barrier.
[0025] Since the surface of cement crash barriers is usually not smooth, if the fixing plate 22 is fixed, the inner side of the fixing plate 22 may not be able to fit against the surface of the crash barrier, which affects the fixation between the fixing plate 22 and the crash barrier. To solve this technical problem, sliding grooves 25 are provided on both sides of the sleeve 21. A translation plate 26 is slidably connected inside the sliding groove 25. The side of the fixing plate 22 is rotatably mounted on the translation plate 26. An arc-shaped connecting rod 27 is fixedly connected between the two fixing plates 22. Pulling the connecting rod 27 can drive the two fixing plates 22 to rotate. The translation plate 26 can slide the fixing plate 22 to a suitable position and rotate the fixing plate 22 to fit against the crash barrier. In this way, the fixing plate 22 can better adapt to the curved or irregular surface of the crash barrier, which facilitates the subsequent fixing operation of the fixing plate 22 and further ensures the stability of the steel support 1, enhancing the wind and earthquake resistance of the overall structure.
