Description

Technical Field

[0001] This application relates to the field of highway infrastructure technology, and in particular to a highway guardrail. Background Technology

[0002] With the development of transportation, there have been many accidents involving large vehicles crossing, overturning, or straddling these guardrails. The two-wave beam guardrails installed on many highways are no longer compatible with the current protection requirements and need to be upgraded. Researchers have successively developed a variety of upgrade and renovation structures for two-wave beam guardrails, including the following two methods: (1) removing the original two-wave beam plates and matching anti-blocking blocks and replacing them with three-wave beam plates and matching anti-blocking blocks; (2) removing the original two-wave beam plates and matching anti-blocking blocks, pulling out the original posts and replacing them with higher posts, or installing sleeves on the original posts to increase their height, and then installing the removed original two-wave beam plates and matching anti-blocking blocks, and adding a new row of two-wave beam plates and matching anti-blocking blocks. Both of the above renovation methods require a large amount of material and multiple construction steps, and the cost is also high, so the renovation technology cannot be widely promoted. How to propose a more effective way to utilize existing steel components, while simplifying construction and reducing costs, is the key to whether the two-wave beam guardrail upgrade and renovation technology can be more effectively promoted, thereby improving the guardrail's safety protection capabilities and the level of safe operation of highways.

[0003] Based on the above, a novel two-wave reusable mobile steel guardrail is proposed. As a mobile guardrail, the two-wave reusable mobile guardrail has flexible installation and dismantling capabilities, allowing for rapid repositioning or rearrangement according to road or construction site needs. It utilizes recycled steel or existing guardrails, incorporating the design concepts of resource conservation and mobility, thus emphasizing resource saving and flexibility. It is particularly suitable for scenarios requiring frequent changes to traffic layout or temporary traffic control, such as road construction, traffic accident handling, and large-scale events. Furthermore, it is easy to install and requires minimal materials, not only helping to save resources and reduce costs but also improving the flexibility and efficiency of traffic management. Utility Model Content

[0035] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0036] In the description of this disclosure / application, unless otherwise stated, "a plurality of" means two or more.

[0037] Example 1

[0038] This embodiment provides a highway guardrail, which can be installed in the median strip of a highway or on both sides of the road, such as... Figure 1 As shown, it includes:

[0039] The guardrail includes at least one first support unit located at one end; multiple second support units; both the first and second support units are vertically fixed to the ground, connected by a first connecting component, and adjacent second support units are connected by a second connecting component; the second connecting component connects a horizontally arranged top guardrail and a waist guardrail. The first and second support units are independent unit devices, connected by the first connecting component, and adjacent second support units are connected by the second connecting component. This design allows for rapid adjustment of the number of guardrail unit devices during construction based on the length of the protected area, enabling reasonable adjustment of the guardrail setup and flexible increase or decrease in the length of the guardrail unit devices. The unitized structure can fully utilize scrap steel or old highway guardrails, producing a stable structure, significantly reducing the need for new materials, lowering resource consumption, and reducing costs.

[0040] Optionally, the length, width, height, and other specifications of the guardrail can be adjusted according to specific needs. The guardrail features a movable design, and each guardrail unit is easy to disassemble and reassemble, thus possessing high recycling value. These guardrails can be reused in reconstruction and expansion projects and on ramps, reducing resource waste.

[0041] like Figure 1-5 The diagram shows the front view of a highway guardrail. The first support unit includes a first post 51, and the second support unit includes a second post 52. Flanges 9 are respectively installed at the bottom of both post 51 and post 52. The flanges 9 are fixed to the ground by anchor bolts 10. Reinforcing ribs 13 are respectively installed on the lower outer sides of post 51 and post 52, and on the upper part of flanges 9. The structure of the anchor bolts 10 and flanges 9 can transmit various forces and moments borne by the posts and their upper structures, including vertical forces, horizontal forces, and torques, effectively distributing these forces to the ground and preventing damage to the posts due to uneven stress. The presence of the reinforcing ribs 13 also significantly improves the load-bearing capacity and rigidity of the connection between the posts and flanges 9, making the entire structure more stable and reliable when bearing external loads.

[0042] Example 2

[0043] This embodiment is an improvement upon embodiment 1, specifically including the following aspects:

[0044] Optionally, the first connecting assembly includes a first top plate 21 and a second top plate 22. The first top plate 21 and the second top plate 22 are detachably installed on the tops of columns 51 and 52, respectively, facilitating reinstallation and making maintenance and replacement more convenient, reducing maintenance costs and time. Stiffeners 4 are fixedly connected to the lower parts of the first top plate 21 and the second top plate 22, and to both sides of the upper ends of columns 51 and 52. The stiffeners 4 serve as the main supporting structure, providing sufficient rigidity and strength to bear and distribute the external loads on the first top plate 21 and the second top plate 22. The connection between the first top plate 21 and the second top plate 22 and the stiffeners 4 ensures the integrity and stability of the structure. In this configuration, the load of the first top plate 21 is first transferred to the stiffeners 4, and then from the stiffeners 4 to the entire structural system, ensuring the reliability and durability of the structure. The first top plate 21 and the second top plate 22 are connected to the stiffening plate 4 by bolts. One side of the first top plate 21 has an extension section one, and one side of the second top plate 22 has an extension section two. Extension section one and extension section two cooperate to connect column one 51 and column two 52. A first set of extension plates 11 are fixedly connected to column one 51 and column two 52 respectively. The two extension plates 11 face each other and are staggered, further enhancing the connection strength between the columns and improving the stability and load-bearing capacity of the overall structure. The extension plates 11 are located below the stiffening plate 4. Pins 2 pass through extension section one, extension section two, and extension plate 11 in sequence, facilitating installation and disassembly and reducing construction difficulty and cost. Simultaneously, during subsequent maintenance, damaged parts can be more easily inspected and replaced, thereby extending the service life of the overall structure and reducing maintenance costs.

[0045] Example 3

[0046] This embodiment is an improvement upon embodiment 1, specifically including the following aspects:

[0047] Optionally, the top guardrail is a crossbeam 3 connected between the second top plate 22 at the top of each adjacent post 52. The crossbeam 3 is located on one side of the second top plate 22. Similar to the two wave plates 12, the crossbeam 3 is also set along the extension direction of the road. The crossbeam 3 is connected to the second top plate 22 by bolts, and two adjacent crossbeams 3 are connected at the ends to form a whole. The crossbeam 3 enhances the stability and structural strength of the highway guardrail. Furthermore, the crossbeam 3 and the two wave plates 12 are set parallel to each other vertically, and the two can jointly intercept vehicles that deviate from the normal driving direction, thereby improving the impact energy that the highway guardrail can withstand and making it less likely to collapse during a collision. In this way, it effectively prevents vehicles from riding over or passing through the guardrail and improves the safety protection performance of the highway guardrail.

[0048] like Figure 1 The image shows a front view of a highway guardrail. The waist guardrail includes: channel steel 71 and channel steel 72, which are fixedly connected to the vertical direction of post 1 51 and post 2 52, respectively; brackets 6 are fixedly connected to the surfaces of channel steel 71 and channel steel 72, respectively; and two wave plates 12 are fixedly connected to channel steel 72. This structure improves the impact energy that the highway guardrail can withstand and can effectively prevent out-of-control vehicles from riding over or crossing the guardrail or avoid accidents such as vehicle rollover.

[0049] like Figure 2 , 5 The image shows a side view of a highway guardrail. The bracket 6 can be directly fixed to the channel steel 72. The bracket 6 is set along the extension direction of the road. In the event of a traffic accident, the bracket 6 and the two wave plates 12 can intercept vehicles that deviate from the normal driving direction, prevent vehicles from entering the opposite lane or outside the road, reduce the losses caused by the accident, and protect the lives of drivers and passengers.

[0050] Optionally, the two-wave plate 12 is tightly connected to the bracket 6, which ensures the stability of the guardrail during normal use and allows for a certain degree of deformation upon impact to absorb collision energy and reduce damage to vehicles and passengers. When the guardrail needs to be replaced or repaired, the bracket 6 and the two-wave plate 12 can be separated without damaging the entire structure, improving the flexibility and efficiency of maintenance.

[0051] It is understandable that the number of components in this highway guardrail, including the first top plate 21, the second top plate 22, the pin 2, the crossbeam 3, the reinforcing plate 4, the first post 51, the second post 52, the bracket 6, the first channel steel 71, the second channel steel 72, the reinforcing plate 8, the flange 9, the anchor bolt 10, the extension plate 11, the two-wave plate 12, and the reinforcing rib plate 13, are all multiple. Here, there is no limit to the number.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
