Description

Technical Field

[0001] This utility model relates to the field of crash barrier technology, specifically to a lightweight prefabricated crash barrier for use on mountain highways. Background Technology

[0002] Highway crash barriers are traffic safety facilities installed on both sides of highways and bridges. They absorb collision energy through the coordinated deformation of the soil base, posts and beams, forcing out-of-control vehicles to change direction and reduce accident losses. Highway crash barriers are a core component of traffic infrastructure and are mainly used for safety protection and isolation on highways.

[0003] Mountainous highways are characterized by complex terrain, significant elevation changes, numerous curves, and frequent slope variations. Traditional crash barriers are typically made of reinforced concrete or heavy steel, resulting in substantial weight. Therefore, large equipment is required for transportation and installation in mountainous areas.

[0004] Therefore, the installation of traditional crash barriers is complicated due to their heavy weight and high installation difficulty, requiring the assistance of large hoisting equipment, which increases the installation cost and construction period. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a lightweight prefabricated crash barrier for mountain highways, which can effectively solve the problems mentioned in the background art.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1: Reference Figure 1-2 The first embodiment of this utility model discloses a lightweight prefabricated crash barrier for mountain highways, including a post 1; The column 1 is provided with two sets, front and rear, and the base plate 2 is fixedly installed at the bottom of the column 1; The anti-collision component is set on one side of the column 1. The anti-collision component includes the guardrail body 3. The guardrail body 3 is installed on one side of the two sets of columns 1. The outer surface of the guardrail body 3 is provided with reflective strips 14, and multiple sets of reflective strips 14 are evenly arranged. The column 1 is made of high-strength aluminum alloy and has a hollow tubular structure. The base 2 has multiple mounting holes and is fixed to the foundation ground of the mountain highway by expansion nails. This structural design ensures the strength of the column 1 while greatly reducing its own weight. The hollow part of the column 1 is also filled with lightweight foam material to further enhance its impact resistance. The cross-section of the guardrail body 3 is wavy. This shape not only ensures the bending resistance of the guardrail body 3, but also reduces the weight. It can deform to a certain extent when it is hit by a vehicle, thereby absorbing the collision energy.

[0020] Example 2: Reference Figure 3-4This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that it includes a fixing component. The fixing component is located between the post 1 and the guardrail body 3. The fixing component includes a connector 4, which is located on one side of the top of the post 1. A bolt 5 passes through the inner side of the connector 4, and the bolt 5 is arranged in two sets, upper and lower. The bolt 5 is installed inside the post 1 by threaded insertion. The fixing component also includes a mounting plate 6, which is welded to one side of the guardrail body 3. The mounting plate 6 is arranged in two sets, left and right. A clamping block 7 is provided on the side of the mounting plate 6 near the connector 4, and the clamping block 7 is arranged in two symmetrical sets, upper and lower. Slide grooves 10 are provided at both the upper and lower ends of the mounting plate 6. A screw 12 is installed at the bottom of the slide groove 10 via a bearing, and the top of the screw 12 passes through the top of the slide groove 10 and is fixedly installed with a knob 13. A slider 8 is fixedly installed on one side of the clamping block 7, and the slider 8 engages with the slide groove 10 and slides in connection with the slide groove 10. The screw 12 passes through the middle of the slider 8 by thread, thus realizing the function of quickly installing the guardrail body 3. The inner wall of the clamping block 7 is pressed with a rubber pad, and the rubber pad is in close contact with the inner wall of the connector 4, which helps to keep the connection stable, reduce the friction between the connectors, and thus increase the service life of the parts. Limiting blocks 9 are fixedly installed on both the left and right sides of the slider 8, and limiting grooves 11 are opened on both the left and right sides of the slide groove 10. The limiting blocks 9 are embedded in the limiting grooves 11 and are slidably connected to the limiting grooves 11, thereby realizing the limiting function of the slide groove 10 movement and preventing excessive internal friction between the screw 12 and the slider 8, which would cause the screw 12 surface to strip.

[0021] The remaining structure is the same as that in Example 1.

[0022] The workflow of this utility model is as follows: First, place the column 1 and chassis 2 at the designated location beside the road, drill holes in the road surface, and install the chassis 2 on the road surface using expansion bolts; Next, attach one side of the connector 4 to the top side of the column 1, and fix the connector 4 to one side of the column 1 by screwing in the bolt 5; Finally, attach the guardrail body 3 to the other side of the two sets of connectors 4 so that the two sets of mounting plates 6 can be aligned with the two sets of connectors 4. After alignment, turn the knob 13. The knob 13 can drive the screw 12 to rotate. The screw 12 can drive the slider 8 to move downward in the slide groove 10, which in turn drives the clamping block 7 to move downward. The clamping block 7 can then be inserted into the interior of the connector 4. At the same time, the limiting block 9 will also slide inside the limiting groove 11. Then turn the lower knob 13 to drive the clamping block 7 to move upward and lock it into the bottom of the connector 4, thus completing the installation.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
