Abstract
Description
Technical Field
[0001] This utility model belongs to the field of guardrail technology, and in particular relates to a high-strength bridge safety guardrail. Background Technology
[0002] In the field of bridge safety protection, traditional guardrails mainly serve a simple barrier function to prevent pedestrians or vehicles from accidentally falling. However, with increasing traffic flow and heightened public awareness of safety, traditional guardrails are gradually failing to meet the functional and safety requirements of modern bridge safety protection. Especially in certain special locations, such as highway bridges and urban viaducts, higher demands are placed on the crashworthiness, anti-climbing performance, and overall stability of guardrails.
[0003] Traditional guardrails often lack sufficient energy absorption and cushioning capacity, making them prone to causing serious secondary injuries upon vehicle collisions. Furthermore, their anti-climbing performance is weak, failing to effectively prevent pedestrians or unauthorized intruders from climbing them. In addition, the overall structure of traditional guardrails is relatively simple, lacking sufficient stability and durability, making them unsuitable for long-term use.
[0004] Therefore, it is essential to invent a high-strength bridge safety guardrail. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a high-strength bridge safety guardrail, including energy-absorbing buffer supports, anti-climbing rollers, and barrier mesh panels. Several energy-absorbing buffer supports are provided, and several anti-climbing rollers are rotatably installed on every two energy-absorbing buffer supports, and two barrier mesh panels are fixedly installed. The anti-climbing rollers are located on the outside of the barrier mesh panels.
[0006] Preferably, the anti-climb rollers are arranged vertically and parallel to each other, and the anti-climb rollers have a hollow structure with a smooth outer surface.
[0007] Preferably, the energy-absorbing buffer support includes a support frame, an energy-absorbing seat, an energy-absorbing mounting plate, and a mounting plate. At least two energy-absorbing seats are fixedly installed on the surface of the support frame. Several mounting plates are provided on the energy-absorbing mounting plates fixedly installed on the energy-absorbing seats. The mounting plates are rotatably connected to the ends of the anti-climb rollers. The support frame is fixed to the barrier mesh.
[0008] Preferably, the thickness of the mounting plate is less than the width of a finger, and its thickness does not exceed three centimeters. The mounting plate has a "U" shaped structure.
[0009] Preferably, the energy-absorbing base is a hollow rectangular structure, and the energy-absorbing base is installed between the support frame and the mounting plate. The four corner edges of the energy-absorbing base are evenly and reasonably provided with energy-absorbing buffer openings, and several energy-absorbing buffer openings are provided.
[0010] Preferably, a reinforcing rod is fixedly installed between the support frames of the two energy-absorbing buffer supports. The reinforcing rod is located on the inner side of the barrier mesh plate, and the support frame is a right-angled triangular frame structure.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This invention effectively enhances the energy absorption and buffering capacity of the guardrail during vehicle impacts by incorporating energy-absorbing buffer supports with hollow rectangular structures and energy-absorbing buffer openings, thereby significantly reducing injury to vehicles and passengers. Simultaneously, the vertical distribution and smooth outer surface design of the anti-climb rollers, combined with the energy-absorbing buffer supports and barrier mesh panels, form a complete and difficult-to-climb protective system, significantly enhancing the guardrail's anti-climb performance. Furthermore, the right-angled triangular frame structure of the support frame and the addition of reinforcing members ensure the guardrail remains stable under external forces, preventing deformation or collapse, further improving overall stability and durability.

[0020] As attached Figure 1 To be continued Figure 3 As shown:
[0021] The high-strength bridge safety guardrail provided by this utility model includes an energy-absorbing buffer support 1, an anti-climbing roller 2, and a barrier mesh 3. Several energy-absorbing buffer supports 1 are provided, and several anti-climbing rollers 2 are rotatably installed on every two energy-absorbing buffer supports 1, and two barrier mesh 3 are fixedly installed. The anti-climbing rollers 2 are located on the outside of the barrier mesh 3.
[0022] Furthermore, the anti-climb rollers 2 are vertically distributed and arranged parallel to each other. This layout is not only aesthetically pleasing but also effectively prevents climbing. The anti-climb rollers 2 have a hollow structure, which reduces the overall weight while maintaining a certain level of strength and rigidity. Their outer surface is smooth, making climbing extremely difficult and further enhancing the anti-climb performance of the guardrail.
[0023] Furthermore, the energy-absorbing buffer support 1 includes a support frame 11, an energy-absorbing seat 12, an energy-absorbing mounting plate 13, and a mounting plate 14. At least two energy-absorbing seats 12 are fixedly installed on the surface of the support frame 11. Several mounting plates 14 are provided on the energy-absorbing mounting plate 13 fixedly installed on the energy-absorbing seat 12. The mounting plate 14 is rotatably connected to the end of the anti-climb roller 2. The support frame 11 is fixed to the barrier mesh plate 3.
[0024] Furthermore, the thickness of the mounting plate 14 is less than the width of a finger, and its thickness does not exceed three centimeters. This design ensures the stable installation of the anti-climb roller 2 while avoiding the creation of climbing points due to an excessively large mounting plate 14. At the same time, the mounting plate 14 adopts a "U"-shaped structure, which not only facilitates installation and disassembly but also increases the overall stability and durability to a certain extent.
[0025] Furthermore, the energy-absorbing base 12 has a hollow rectangular structure, which allows it to deform upon impact, thereby absorbing and dispersing impact energy. The energy-absorbing base 12 is installed between the support frame 11 and the mounting plate 14, with energy-absorbing buffer openings 15 evenly and rationally provided at its four corners. These energy-absorbing buffer openings 15 further enhance the energy-absorbing and buffering effect, enabling the guardrail to better protect the safety of vehicles and passengers during vehicle collisions.
[0026] Furthermore, a reinforcing rod is fixedly installed between the support frames 11 of the two energy-absorbing buffer supports 1. This reinforcing rod is located on the inner side of the barrier mesh 3, which enhances the overall stability and durability. At the same time, the support frame 11 adopts a right-angled triangular frame structure design, which enables the guardrail to remain stable when subjected to external forces and is not prone to deformation or collapse.
[0027] The working principle is as follows: First, when a vehicle collides with the guardrail, the energy-absorbing buffer support 1 plays a crucial role. During the collision, the vehicle first comes into contact with the anti-climb roller 2. Because the rollers are rotatable and have a hollow structure, they can, to a certain extent, prevent the vehicle from directly impacting the rigid support structure. Subsequently, the impact force of the vehicle is transferred to the energy-absorbing seat 12.
[0028] As a key energy-absorbing component, the energy-absorbing seat 12's hollow rectangular structure allows it to deform upon impact. This deformation effectively absorbs the vehicle's impact energy and disperses it into the surrounding support structure. Simultaneously, energy-absorbing buffer openings 15 at the four corners of the energy-absorbing seat 12 further enhance the energy-absorbing effect. These buffer openings 15 deform upon impact, thereby absorbing more energy and reducing the vehicle's impact speed.
[0029] Secondly, the vertical distribution and parallel arrangement of the anti-climb rollers 2 make climbing extremely difficult. Simultaneously, the hollow structure and smooth surface design of the anti-climb rollers 2 further enhance their strength and rigidity, providing a certain degree of impact absorption and preventing climbing. Even if someone attempts to climb, the smooth surface of the rollers makes climbing very difficult, effectively deterring such behavior.
[0030] In addition, the barrier mesh panel 3, as another important component of the guardrail, serves to prevent people or objects from falling from the edge of the bridge. The barrier mesh panel 3 is fixedly connected to the support frame 11, forming a complete protective system. Even if a person or object accidentally comes into contact with the guardrail, the barrier mesh panel 3 provides additional safety.
[0031] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
