Description

[Technical Field]

[0002] This utility model relates to the field of highway renovation technology, and in particular to a highway guardrail reuse and renovation component and a corresponding highway renovation guardrail. [Background Technology]

[0004] With years of operation of highways and continuous updates to traffic safety technical standards, existing old highway guardrails have gradually revealed their incompatibility with current safety requirements. These old guardrails were mostly installed and constructed according to early industry specifications, and their protective strength is inadequate in the face of today's complex traffic environment and higher safety standards.

[0005] To improve highway safety, a direct and effective method is to upgrade existing guardrails. However, completely removing and reinstalling new guardrails is not only costly, but the old guardrails are often difficult to reuse, resulting in a significant waste of resources. [Utility Model Content]

[0007] The purpose of this utility model is to provide a highway guardrail renovation component and corresponding highway renovation guardrail that can be upgraded and transformed on the basis of old guardrails, in order to solve the above-mentioned problems in the current guardrail upgrade and transformation.

[0008] This utility model is achieved through the following technical solution:

[0009] A highway guardrail renovation component includes an extension post for connecting with the original guardrail post, a crossbeam assembly between any two adjacent extension posts, the extension post including an installation section connected to the crossbeam assembly, a first gradient section with a gradually decreasing outer diameter from top to bottom connected below the installation section, and a second gradient section with a gradually decreasing outer diameter from top to bottom connected below the first gradient section.

[0010] As described above, in a highway guardrail renovation component, one side of the installation section is provided with a support frame that connects to the crossbeam assembly.

[0011] As described above, a highway guardrail renovation component includes a support frame comprising a side connecting plate adapted to the shape of the installation section and detachably connected thereto. The side connecting plate is provided with an upper connecting plate and a lower connecting plate respectively corresponding to the upper and lower parts of the crossbeam assembly, for detachably connecting to the crossbeam assembly.

[0012] As described above, a highway guardrail renovation component includes a crossbeam assembly comprising a protective beam and a connector for connecting any two adjacent protective beams.

[0013] As described above, a highway guardrail renovation component is provided, wherein the protective beam is a hollow metal tube with a closed cross-section, and the connector is a conforming part adapted to the shape of the protective beam, which is sleeved with any two adjacent protective beams to connect the two into a whole.

[0014] As described above, in a highway guardrail renovation component, the protective beam is a D-shaped steel pipe, and the upper and lower ends of the protective beam are respectively provided with multiple first mounting holes. The upper and lower ends of the connecting piece are respectively provided with multiple second mounting holes. The upper connecting plate and the lower connecting plate are respectively provided with multiple corresponding third mounting holes. The first mounting holes, second mounting holes, and third mounting holes can be assembled using fasteners.

[0015] As described above, in a highway guardrail renovation component, the mounting section has at least three vertically arranged fourth mounting holes, and the side connecting plate has at least two vertically arranged fifth mounting holes. The fifth mounting holes can be assembled with the fourth mounting holes using fasteners. The number of fourth mounting holes is greater than the number of fifth mounting holes to facilitate adjustment of the height of the crossbeam assembly.

[0016] As described above, a highway guardrail renovation component has a rubber gasket fitted on the first gradient section and a sixth mounting hole on the second gradient section for fixing to the original guardrail post with fasteners.

[0017] A highway guardrail renovation project includes posts with detachably connected anti-blocking blocks on each post. A guardrail panel is provided between any two adjacent posts, and the two sides of the guardrail panel are detachably connected to the anti-blocking blocks on the two adjacent posts respectively. A highway guardrail renovation component as described in any one of the claims is connected above the posts.

[0018] As described above, in a highway renovation guardrail, the anti-blocking block has multiple vertically arranged sixth mounting holes, which facilitates the simultaneous adjustment of the guardrail panel's installation height when the road surface is raised.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. By designing extension posts that can be seamlessly integrated with existing guardrail posts, the existing posts are fully utilized, resources are avoided, and the cost of upgrading and renovating the guardrail is significantly reduced. The first and second transition sections of the extension posts ensure a tight connection between them and the original guardrail posts.

[0021] 2. By installing crossbeam assemblies between adjacent extension posts, the overall protective strength and stability of the guardrail are enhanced. Simultaneously, the support frame further strengthens the connection between the crossbeam assemblies and the extension posts, making the entire structure more stable.

[0022] 3. By incorporating multiple vertically arranged mounting holes in the design of the installation section and support frame, the height of the crossbeam assembly is adjustable. This allows the guardrail system to adapt to different road surface heights and installation requirements, improving the applicability and flexibility of the guardrail. [Attached Image Description]

Detailed Implementation Methods

[0034] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0035] Example 1: Please refer to Figures 1 to 4This embodiment provides a highway guardrail renovation component, which aims to achieve an efficient, stable, and aesthetically pleasing upgrade of existing highway guardrails while making full use of the original guardrail posts and reducing resource waste. It includes an extension post 1 for connecting with the original guardrail posts, and a crossbeam assembly 2 between any two adjacent extension posts 1. The extension post 1 includes an installation section 11 connected to the crossbeam assembly 2. A first gradient section 12 with a gradually decreasing outer diameter from top to bottom is connected below the installation section 11, and a second gradient section 13 with a gradually decreasing outer diameter from top to bottom is connected below the first gradient section 12.

[0036] In this embodiment, the installation section 11 is located above the extension post 1 and is directly connected to the crossbeam assembly 2, ensuring that the crossbeam assembly 2 is stably installed at the predetermined height. This section is designed to facilitate quick docking and fixing with the crossbeam assembly, and can be connected by bolts or welding. Immediately below the installation section 11, the first gradient section 12 is designed with an outer diameter that gradually decreases from top to bottom. The purpose of this section is to abut against the upper end of the original guardrail post, facilitating a tight fit with the original guardrail post during the fitting process. It can also effectively disperse the stress generated by external forces such as impacts, enhancing the stability of the overall structure. The second gradient section 13 is located below the first gradient section 12. It also adopts a design where the outer diameter gradually decreases from top to bottom. Unlike the first gradient section 12, the overall diameter of the second gradient section 13 is slightly smaller than the inner wall of the original guardrail post, so that it can easily extend into the original guardrail post. This allows the second gradient section 13 to easily extend into the original guardrail post and form a tight fit with the inner wall of the original guardrail post, further enhancing the connection between the extension post and the original guardrail post.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the support frame 3 includes a side connecting plate 31 that is adapted to the shape of the mounting section 11 and is detachably connected thereto. The side connecting plate 31 is provided with an upper connecting plate 32 and a lower connecting plate 33 that correspond to the upper and lower parts of the crossbeam assembly 2, respectively, for detachable connection with the crossbeam assembly 2.

[0038] In this embodiment, a support frame 3 connected to the crossbeam assembly 2 is added to one side of the installation section 11. This design not only enhances the connection strength between the crossbeam assembly and the extension post, but also provides more installation and adjustment space to adapt to guardrail renovation projects of different specifications and requirements. The shape of the side connecting plate 31 is adapted to the installation section 11 and is tightly fitted to the installation section 11 through a detachable connection method such as bolt connection. This design allows the support frame to be easily installed or removed, facilitating maintenance and replacement.

[0039] The upper connecting plate 32 and the lower connecting plate 33 are respectively disposed on the side connecting plate 31, corresponding to the upper and lower parts of the crossbeam assembly 2. The detachable connection between the upper and lower connecting plates and the crossbeam assembly, such as bolt connection, ensures the stable installation of the crossbeam assembly 2 at the predetermined height.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the beam assembly 2 includes a protective beam 21 and a connector 22 for connecting any two adjacent protective beams 21.

[0041] In this embodiment, the protective beam 21 serves as the main protective component of the guardrail, acting to block and buffer external impacts. The protective beam can be made of high-strength materials to ensure sufficient strength and durability. The connector 22 connects any two adjacent protective beams 21, ensuring the continuity and stability of the crossbeam assembly 2 in the horizontal direction. The connector 22 can employ a detachable connection method, such as bolted or plug-in connection, for easy installation and disassembly.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the protective beam 21 is a hollow metal tube with a closed cross-section, and the connector 22 is a contoured component adapted to the shape of the protective beam 21, which is sleeved with any two adjacent protective beams 21 to connect the two into a whole.

[0043] In this embodiment, the hollow metal tube design with a closed cross-section improves the strength and rigidity of the protective beam 21, effectively prevents external corrosion and wear, and extends its service life. Specifically, hollow metal tubes with shapes such as circles, rectangles, and ellipses can be used. The two ends of the connector 22 are respectively sleeved on any two adjacent protective beams 21. Through tight fitting and appropriate fixing methods such as welding, bolt connection, or snap-fit ​​connection, the two are connected as a whole. It should be noted that the connector 22 can be selected to be sleeved inside the two protective beams 21. In some other embodiments, a connector 22 with a diameter larger than that of the protective beam 21 can also be selected, sleeved on two adjacent protective beams 22, and then fixed.

[0044] Furthermore, the protective beam 21 is a D-shaped steel pipe fitting. Multiple first mounting holes 211 are respectively provided on the upper and lower ends of the protective beam 21. Multiple second mounting holes 221 are respectively provided on the upper and lower ends of the connecting member 22. Multiple corresponding third mounting holes 321 are respectively provided on the upper connecting plate 32 and the lower connecting plate 33. The first mounting holes 211, second mounting holes 221, and third mounting holes 321 can be assembled using fasteners. Specifically, fasteners such as bolts and nuts can be inserted into the first mounting holes 211, second mounting holes 221, and third mounting holes 321 and tightened to achieve a stable connection between the protective beam 21, the connecting member 22, and the support frame 3. In addition, the D-shaped steel pipe fitting has high structural strength and stability. This shape of the protective beam 21 can effectively disperse and withstand forces from different directions, making the entire structure more robust and durable.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, the mounting section 11 has at least three vertically arranged fourth mounting holes 111, and the side connecting plate 31 has at least two vertically arranged fifth mounting holes 311. The fifth mounting holes 311 can be assembled with the fourth mounting holes 111 by fasteners such as bolts. The number of fourth mounting holes 111 is greater than the number of fifth mounting holes 311 in order to facilitate the adjustment of the height of the crossbeam assembly 2.

[0046] In this implementation, the height of the crossbeam assembly 2 is adjustable by designing different numbers of fourth mounting holes 111 and fifth mounting holes 311. This makes the entire guardrail system more flexible and adaptable to different installation requirements. For example, when the road surface needs to be over-paved, the installation height of the crossbeam assembly 2 can be adjusted to keep the guardrail at the same height as the actual vehicle.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, a rubber washer 4 is fitted onto the first transition section 12, and a sixth mounting hole 131 is provided on the second transition section 13 for fixing to the original guardrail post with fasteners. The rubber washer 4 can effectively absorb vibrations caused by external forces such as vehicle impacts or wind pressure, reduce the impact on the guardrail structure, protect the guardrail and surrounding facilities, and also provide a certain sealing effect to prevent moisture, dust and other impurities from entering the original guardrail post.

[0048] Example 2: With years of operation on highways and continuous updates to traffic safety product usage standards, existing guardrails on older highways can no longer meet current safety requirements. Especially after the installation of ETC gantries, marker poles, and other obstacles, higher demands are placed on the protective strength of the guardrails. To reduce renovation costs and avoid resource waste, this example proposes an upgrade design scheme based on existing guardrails. Through modular and detachable connection methods, the upgrade improves the flexibility, maintainability, and safety of the guardrails while reducing renovation costs and achieving rational resource utilization.

[0049] Specifically, please see Figures 5 to 8 A highway guardrail renovation project includes a post 5, on which a blocking block 6 is detachably connected. A guardrail plate 7 is provided between any two adjacent posts 5. The two sides of the guardrail plate 7 are detachably connected to the blocking blocks 6 on the two adjacent posts 5 respectively. A highway guardrail renovation component as proposed in Embodiment 1 is installed on the top of the post 5.

[0050] In the actual modification process, the column cap of column 5 needs to be removed first. Then, the second transition section 13 of the height-adjusting column 1 in Embodiment 1 is inserted into column 5. Column 5 has assembly holes, which are fixedly connected to the sixth mounting holes 131 on the second transition section 13 using fasteners such as bolts. The first transition section 12 of the height-adjusting column 1 is clamped and tightly fitted to the upper end of column 5. To ensure a tighter connection between the second transition section 13 and the inner wall of column 5, three or more steel balls can be placed between the second transition section 13 and the inner wall of column 5 to increase the connection points and prevent the height-adjusting column 1 from shaking. After the height-adjusting column 1 is installed, the support frame 3 proposed in Embodiment 1 is installed on the height-adjusting column 1. Finally, the crossbeam assembly 2 is installed to complete the modification.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, the anti-blocking block 6 has multiple vertically arranged seventh mounting holes 61, which are fixed to the corresponding mounting holes on the post 5 using fasteners such as bolts. This allows for simultaneous adjustment of the guardrail plate 7's height when the road surface is raised. Road surface raising is a common phenomenon during highway reconstruction and expansion. Traditional guardrail designs often cannot adapt to changes in road surface height, leading to a reduction in the guardrail's protective effect. To solve this problem, this embodiment provides multiple vertically arranged seventh mounting holes 61 on the anti-blocking block 6, enabling simultaneous adjustment of the guardrail plate 7's height when the road surface is raised.

[0052] For details, please refer to Figures 7 to 8When the road surface is raised, the corresponding seventh mounting hole 61 can be selected according to the height increase, and the guardrail 7 can be reinstalled at a suitable height. In this way, it can be ensured that the guardrail 7 always maintains an appropriate height difference with the road surface, thereby maintaining its effective protective function. It should be noted that the design of multiple fourth mounting holes 111 in the mounting section 11 in Embodiment 1 also has the same function, which is only emphasized here and will not be elaborated further.

[0053] Working principle of this utility model:

[0054] This utility model provides a component for the renovation and upgrading of existing highway guardrails, aiming to achieve efficient, stable, and economical upgrades. The component mainly includes extension posts, crossbeam assemblies, and support frames. The extension posts are fitted together with the original guardrail posts to increase their height. Their design includes an installation section, a first transition section, and a second transition section, which fit tightly against the crossbeam assembly and the original guardrail post, respectively. The crossbeam assembly is connected to the extension posts via the support frame, enhancing the overall structural stability. Furthermore, this utility model provides an adjustable height function to adapt to the installation requirements of different scenarios.

[0055] Based on the highway guardrail renovation component proposed in this utility model, a highway renovation guardrail is also proposed. This guardrail uses a modular and detachable connection method to add components such as extension posts, anti-blocking blocks, and guardrail panels to the old guardrail, thereby improving the guardrail's flexibility, maintainability, and safety. During the renovation process, the extension posts are tightly fitted onto the old guardrail posts, while the anti-blocking blocks and guardrail panels are connected to the extension posts via a detachable connection. Furthermore, the multiple vertically arranged mounting holes on the anti-blocking blocks allow for simultaneous adjustment of the guardrail panel's height when the road surface is raised, ensuring that the guardrail always maintains an appropriate height difference with the road surface, thus preserving its effective protective function.
