Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a guardrail for highways. Background Art

[0002] Highway guardrail is a highly efficient longitudinal energy absorption structure. Its design principle is to effectively absorb collision energy through its own deformation, thereby adjusting the vehicle's driving trajectory to prevent the vehicle from running off the road or entering the opposite lane, thereby protecting the safety of the vehicle and its passengers in all directions.

[0003] At present, existing highway guardrails usually absorb car impact loads through a buffer structure set on the guardrail. Although this reduces the impact force of the car collision to a certain extent and plays a role in protecting the safety of the vehicle and its passengers, the design fails to consider the impact load force transmission sequence, fails to fully utilize the load-bearing capacity of the guardrail and the column working together, and fails to fully demonstrate the impact resistance of the material itself. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent.

[0005] To this end, one objective of this utility model is to provide a guardrail for highways. By providing a guardrail with a diagonal bracing structure, not only can the guardrail near the column effectively transmit impact forces to the column, but the guardrail also effectively decomposes the external force of the central area of ​​the guardrail when subjected to a strong impact onto the column, thereby transmitting this force to the ground. This fully utilizes the synergistic load-bearing effect between the guardrail and the column, achieves optimized structural performance, and fully demonstrates the inherent impact resistance of the material.

[0006] To achieve the above-mentioned purpose, the first aspect of the utility model proposes a guardrail plate for a highway, comprising two columns, a guardrail plate, two connecting assemblies, two diagonal bracing assemblies and a reinforcing assembly, wherein the two connecting assemblies respectively install the guardrail plate on the columns; the two diagonal bracing assemblies are arranged on the two columns and the guardrail plate, the diagonal bracing assembly includes a diagonal bracing body, a first connecting mechanism and a second connecting mechanism, the diagonal bracing body is arranged on the guardrail plate through the first connecting mechanism; the diagonal bracing body is arranged on the column through the second connecting mechanism; the reinforcing assembly is arranged on the two diagonal bracing assemblies.

[0007] In addition, the guardrail punching device proposed above according to the present invention may also have the following additional technical features:

[0008] Specifically, the connecting assembly includes a first connecting plate, two first bolts and two first nuts; the first connecting plate is arranged on the column; the two first bolts pass through the column and the first connecting plate; and the two first nuts are respectively threadedly connected to the two first bolts.

[0009] Specifically, the first connecting mechanism includes a second connecting plate, two second bolts and two second nuts, wherein the second connecting plate is arranged on the guardrail plate; the two second bolts pass through the guardrail plate, the second connecting plate and the diagonal support body; and the two second nuts are respectively threadedly connected to the two second bolts.

[0010] Specifically, the second connection mechanism includes two third bolts and two third nuts, wherein the two third bolts pass through the column and the diagonal support body; and the two third nuts are respectively threadedly connected to the two third bolts.

[0011] Specifically, the reinforcement assembly includes a reinforcement rod and a spring, wherein the reinforcement rod is fixedly arranged on the two diagonal support bodies, and the spring is arranged on the reinforcement rod.

[0012] Compared with the existing technology, the utility model has the following beneficial effects: the utility model is used for the guardrail of the highway, by providing a guardrail with a diagonal bracing structure, which not only ensures that the guardrail close to the column can effectively transmit the impact force to the column, but also improves the decomposition of the external force in the middle area of ​​the guardrail when it is subjected to a strong impact to the column, and then transmits this force to the ground. This design not only fully promotes the collaborative working efficiency of the column and the guardrail, but also fully taps the impact resistance potential of the material itself, achieving dual optimization of structure and material. In addition, a reinforcement component is configured in the weak area in the middle of the guardrail to make up for the lack of impact load resistance in this area, thereby greatly enhancing the anti-collision performance of the guardrail and ensuring the maximum safety of the vehicle.

DETAILED DESCRIPTION

[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following describes a guardrail plate for a highway according to an embodiment of the present invention with reference to the accompanying drawings.

[0024] like Figures 1-6 As shown, the guardrail plate for highways according to an embodiment of the present invention includes two columns 1, a guardrail plate 2, two connecting components 3, two diagonal bracing components 4 and a reinforcing component 5.

[0025] Among them, two diagonal bracing components 4 are arranged on two columns 1 and guardrail panels 2, two connecting components 3 respectively install the guardrail panels 2 on the columns 1, and the reinforcing components 5 are arranged on the two diagonal bracing components 4.

[0026] The diagonal brace assembly 4 includes a diagonal brace body 41 , a first connecting mechanism 42 and a second connecting mechanism 43 , wherein the diagonal brace body 41 is arranged on the guardrail board 2 through the first connecting mechanism 42 , and the diagonal brace body 41 is arranged on the column 1 through the second connecting mechanism 43 .

[0027] It should be noted that when a car collides with a guardrail, the force on the guardrail board will go through a process of dispersion and transmission, and will eventually be directed to the column. However, this force transmission effect is more ideal on the side of the guardrail board close to the column. In contrast, when the central area encounters an impact force, it is difficult to effectively transfer this force to the column. For example: assuming that a car collides with a guardrail, the bending moment borne by the central area of ​​the guardrail board reaches 1 / 8PL (where P represents the concentrated impact force and L is the distance between the two columns). This phenomenon is particularly significant for guardrail boards with larger spans. The impact force borne in the middle cannot be effectively transferred to the column, thereby increasing the risk of damage. This requires adding two diagonal braces between the guardrail board and the column to decompose the impact load borne by the guardrail board, transfer the force to the column to the greatest extent, and enhance the anti-collision ability of the guardrail board.

[0028] Specifically, during the construction of the guardrail board, the column 1 is fixed to the ground, and the guardrail board 2 is installed on the column 1 through two connecting components 3 respectively. Then, one side of the diagonal brace body 41 is installed on the guardrail board 2 through the first connecting mechanism 42, and the other side of the diagonal brace body 41 is installed on the column 1 through the second connecting mechanism 43. Finally, the reinforcement component 5 is installed between the two diagonal brace components 4.

[0029] When a car strikes guardrail panel 2, the impact load on the guardrail panel near pillar 1 is directly transmitted to pillar 1 through guardrail panel 2. The impact load in the middle of the guardrail panel is also transmitted to pillar 1 through the two diagonal brace assemblies 4. This decomposes the impact load into multiple forces, which are then transmitted to pillar 1 and finally to the ground through pillar 1. This fully utilizes the synergistic effect of guardrail panel 2 and pillar 1 and fully taps the potential of the material. Furthermore, the reinforcement assembly 5, positioned between the two diagonal brace bodies 41, also enhances the collision resistance of the guardrail panel's weakest middle region, thereby improving the collision resistance of guardrail panel 2.

[0030] In one embodiment of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the connection assembly 3 includes a first connection plate 31 , two first bolts 32 and two first nuts 33 .

[0031] The first connecting plate 31 is provided on the column 1 , and two first bolts 32 pass through the column 1 and the first connecting plate 31 . The two first bolts 32 are threadedly connected to the two first nuts 33 respectively.

[0032] Specifically, the guardrail plate 2 is fixed to the column 1 using the first bolt 32 and the first nut 33 .

[0033] In one embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 4and Figure 5 As shown, the first connecting mechanism 42 includes a second connecting plate 421 , two second bolts 422 and two second nuts 423 .

[0034] Among them, the second connecting plate 421 is set on the guardrail plate 2, the two second bolts 422 pass through the guardrail plate 2, the second connecting plate 421 and the diagonal support body 41, and the two second nuts 423 are respectively threadedly connected to the two second bolts 422.

[0035] Specifically, one side of the diagonal support body 41 is fixed to the second connecting plate 421 by using a second nut 423 and a second bolt 422 .

[0036] In one embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the second connection mechanism 43 includes two third bolts 431 and two third nuts 432 .

[0037] The two third bolts 431 pass through the column 1 and the diagonal support body 41 , and the two third nuts 432 are threadedly connected to the two third bolts 431 respectively.

[0038] Specifically, the other side of the diagonal support body 41 is fixed to the second column 1 by using the third nut 432 and the third bolt 431 .

[0039] In one embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the reinforcing assembly 5 includes a reinforcing rod 51 and a spring 52 , wherein the reinforcing rod 51 is fixedly arranged on the two diagonal support bodies 41 , and the spring 52 is arranged on the reinforcing rod 51 .

[0040] It can be understood that the arrangement of the reinforcing rod 51 and the spring 52 can enhance the anti-collision capability of the impact-resistant weak area in the middle of the guardrail.

[0041] Specifically, during the construction of the guardrail board, the column 1 is fixed to the ground, the guardrail board 2 is fixed to the column 1 using the first bolt 32 and the first nut 33, one side of the diagonal brace body 41 is fixed to the second connecting plate 421 using the second nut 423 and the second bolt 422, and the other side of the diagonal brace body 41 is fixed to the column 1 using the third nut 432 and the third bolt 431, and finally the reinforcement component 5 is installed on the two diagonal brace components 4.

[0042] When a car strikes guardrail panel 2, the impact load on the guardrail panel near column 1 is directly transmitted to column 1 through guardrail panel 2. The impact load on the central area of ​​the guardrail panel is also transmitted to column 1 through the two diagonal brace assemblies 4. This effectively breaks down the impact load into multiple forces, which are transmitted to column 1 and finally to the ground through column 1. This fully utilizes the synergistic effect of guardrail panel 2 and column 1 and fully taps the potential of the material. Furthermore, the reinforcement assembly 5, located between the two diagonal brace bodies 41, also enhances the collision resistance of the guardrail panel's weakest mid-span, thereby enhancing the collision resistance of guardrail panel 2.

[0043] In summary, the guardrail used for highways of the present invention, by providing a guardrail with a diagonal bracing structure, not only ensures that the guardrail close to the column can effectively transmit the impact force to the column, but also improves the decomposition of the external force in the middle area of ​​the guardrail when it is subjected to a strong impact to the column, and then transmits this force to the ground. This design not only fully promotes the collaborative working efficiency of the column and the guardrail, but also fully taps the impact resistance potential of the material itself, achieving dual optimization of structure and material. In addition, a reinforcement component is configured in the weak area in the middle of the guardrail to make up for the lack of impact load resistance in this area, thereby greatly enhancing the anti-collision performance of the guardrail and ensuring the maximum safety of the vehicle.
