Description

Technical Field

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

[0002] Highway guardrails are the main form of semi-rigid guardrails. They are a continuous structure made of corrugated steel guardrail panels spliced ​​together and supported by main posts. Highway guardrails use the physical deformation of the soil base, posts and beams to absorb the energy generated by a collision and force out-of-control vehicles to change their direction of travel and return to the normal road direction, preventing vehicles from running off the road.

[0003] We have found the following defects in existing highways:

[0004] 1. Many edges on highways are dangerous, such as deep pits and water bodies. The guardrails mentioned above cannot be used because they are not high enough. The installation cost of corrugated steel guardrail panels and posts is relatively high, so multiple lines of defense are required, which cannot give full play to the advantages of traditional guardrails (protective effect, cost, etc.).

[0005] 2. Traditional guardrail installation components are complex and not convenient enough. In addition to the need for multiple people to assist in bending and installing the corrugated steel guardrail panels, multiple people are also needed to assist in the bolt fixing and connection installation.

[0006] 3. Traditional guardrails have a simple structure. Apart from the guardrails, posts, and installation and connection components, there is no further buffer structure, and the buffering effect on vehicles impacting the guardrail needs to be improved.

[0007] To address the aforementioned shortcomings, we propose a highway guardrail that improves upon the existing guardrail posts and installation components, and combines this with the subsequent installation of corrugated steel guardrail panels to mitigate these deficiencies. Utility Model Content

[0008] The purpose of this utility model is to provide a highway guardrail to address the aforementioned shortcomings in the technology.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a highway guardrail, including a post, with a plurality of mounting support plates equidistantly sleeved around the periphery of the post, the mounting support plates decreasing in size from bottom to top, the upper mounting support plate having a radius of half that of the adjacent lower mounting support plate with the post as the axis, and each mounting support plate having an mounting component placed on it.

[0010] The mounting assembly includes docking seats in the same number as the mounting support plates, and the docking seats are provided with a buffer maintenance ring around their upper outer edge.

[0011] Furthermore, the mounting support plate is welded to the column, and the distance between adjacent mounting support plates is greater than the height of the corrugated steel guardrail.

[0012] Furthermore, the docking seat is welded to the buffer maintenance ring.

[0013] Furthermore, the buffer maintenance ring has progressively smaller docking channels from bottom to top, which are used to pass through mounting support plates that progressively increase in size from top to bottom, thereby allowing the mounting support plates to support the buffer maintenance ring.

[0014] Furthermore, the mounting support plate and the buffer maintenance ring are provided with bolt mounting holes for installation via bolts.

[0015] Furthermore, the docking seat and the buffer maintenance ring are provided with mounting parts on their periphery. The side of the mounting part closest to the docking seat and the buffer maintenance ring is an arc structure to fit and conform to the design. The mounting parts are connected to the pre-drilled mounting holes on the mounting parts by bolts passing through the mounting holes on the corrugated steel guardrail. The mounting holes of the mounting parts are connected to the inner wall of the buffer maintenance ring.

[0016] Furthermore, a drainage hole is provided on the periphery of the buffer maintenance ring near the docking seat.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In the improved guardrail design, multiple equidistant and gradually decreasing mounting support plates are set on the posts. Combined with the buffer maintenance ring, which has a structure that gradually increases in size from top to bottom, the mounting support plates can support it. The design of the docking channel makes the installation process simpler. Just pass the docking seat through the mounting support plate to complete the installation. By increasing the height of the posts, the installation height and number of corrugated steel guardrail panels can be increased.

[0019] Furthermore, the docking installation method allows the corrugated steel guardrail to apply stress to the installation support plate after the installation support plate is connected to the corrugated steel guardrail, thus securing it firmly to the post and reducing the cost of the installation components.

[0020] The design of the installation components also fully considers the protective effect and ease of installation of the guardrail. The combined use of the docking seat and the buffer maintenance ring makes the installation process simpler.

[0021] The docking seat design makes the guardrail installation more stable, while the buffer maintenance ring can provide a certain degree of cushioning when a vehicle crashes, reducing the speed of the vehicle and the intensity of the collision. Attached Figure Description

[0030] Example 1

[0031] like Figure 1-3As shown, this utility model provides a technical solution: a highway guardrail, including a post 1, with a plurality of mounting support plates 2 equidistantly sleeved around the periphery of the post 1. The mounting support plates 2 are designed according to requirements. The post 1 is designed according to the required height and the number of corrugated steel guardrail panels. The mounting support plates 2 gradually decrease in size from bottom to top. The radius of the upper mounting support plate 2 with the post 1 as the axis is half that of the adjacent lower mounting support plate 2. Each mounting support plate 2 is equipped with a mounting component 3. The mounting component 3 includes a docking seat 31 in the same number as the mounting support plates 2. The docking seat 31 is surrounded by a buffer protection ring 32 along its upper outer edge. When a vehicle collides with the guardrail, the buffer protection ring 32 can provide a certain buffering effect to reduce the damage to the vehicle and passengers.

[0032] Example 2

[0033] like Figure 1-3 As shown, the mounting support plate 2 is welded to the post 1, and the distance between adjacent mounting support plates 2 is greater than the height of the corrugated steel guardrail, so as not to affect the installation of the corrugated steel guardrail.

[0034] The docking seat 31 is welded to the buffer maintenance ring 32.

[0035] The buffer maintenance ring 32 has progressively smaller docking channels 33 from bottom to top, which are used to pass through the mounting support plate 2, which progressively increases in size from top to bottom, so that the mounting support plate 2 can support the buffer maintenance ring 32.

[0036] The mounting support plate 2 and the buffer maintenance ring 32 have bolt mounting holes, which are then used for bolt mounting.

[0037] The docking seat 31 and the buffer maintenance ring 32 are provided with a mounting part 34. The side of the mounting part 34 near the docking seat 31 and the buffer maintenance ring 32 is an arc structure to fit and conform to the shape of the docking seat 31 and the buffer maintenance ring 32. The mounting part 34 is connected to the mounting hole reserved on the mounting part 34 by bolts passing through the mounting hole on the corrugated steel guardrail plate. The mounting hole of the mounting part 34 is connected to the inner wall of the buffer maintenance ring 32.

[0038] A drain hole 35 is provided on the outer periphery of the buffer maintenance ring 32 near the docking seat 31 to drain water from the buffer maintenance ring 32.

[0039] The installation process of this utility model is as follows: First, the post 1 needs to be installed at the edge of the road. The post 1 can be fixed in the soil by a concrete foundation. The installation component 3 is placed on each installation support plate 2. The buffer maintenance ring 32 has progressively smaller docking channels 33 from bottom to top, which are used to pass through the progressively larger installation support plates 2 from top to bottom. In this way, the installation support plate 2 can support the buffer maintenance ring 32 and then fix it with bolts. The installation component 3 is fixed to the post 1 with bolts. The bolts pass through the installation holes on the corrugated steel guardrail plate and connect it to the reserved installation holes on the installation component 34, and connect it to the inner wall of the buffer maintenance ring 32. The corrugated steel guardrail plate is fixed to the guardrail post 1 by locking with nuts.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
