Description

Technical Field

[0001] This utility model relates to the field of corrugated guardrail technology, and in particular to a high-strength steel lightweight multi-layer anti-collision guardrail. Background Technology

[0002] High-strength steel lightweight corrugated beam guardrails are protective facilities designed specifically for highways and urban roads. They achieve lightweighting by using high-strength steel while maintaining excellent impact resistance.

[0003] Existing corrugated guardrails are usually made of thin steel plates and installed between two posts. They are relatively long and can still deform to varying degrees when impacted, which reduces their service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-strength steel lightweight multi-layer anti-collision guardrail. By setting up support components, uniformly arranged corrugated support plates are added to the long corrugated plate to improve the strength of the corrugated plate, reduce the degree of deformation of the corrugated plate, and extend the service life of the corrugated guardrail.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a high-strength steel lightweight multi-layer anti-collision guardrail, comprising: a corrugated guardrail, wherein the corrugated guardrail includes posts and corrugated plates, and the corrugated plates are fixed between two posts;

[0006] The support assembly includes a support pipe, a connecting pipe, and a corrugated support plate. The support pipe is fixed between the two columns, the connecting pipe is fixed to the side of the support pipe, and the corrugated support plate is welded to the other end of the support pipe and is close to the side of the corrugated plate.

[0007] As a further embodiment of this utility model: the support assembly further includes a first U-shaped connector, a square through hole, a mounting plate, and a mounting hole. The first U-shaped connector is fixed to the upper section of the column by bolts, and both ends of the support tube are fixed to the first U-shaped connector by bolts. The square through hole is opened in the middle of the support tube. The mounting plate is welded to one end of the connector, and the mounting hole is opened on the mounting plate. The square through hole and the mounting hole are connected by bolts.

[0008] As a further embodiment of this utility model: the support assembly further includes a waveform damping pad, which is fixed to the side of the waveform support plate and is in close contact with the side of the waveform plate.

[0009] As a further embodiment of this utility model: the waveform plate, the waveform support plate, and the waveform damping pad have the same curvature.

[0010] As a further embodiment of this utility model, the corrugated guardrail also includes a V-shaped connector, which is fixed between the post and the corrugated plate by bolts.

[0011] As a further aspect of this utility model, it also includes:

[0012] The reinforcing component includes a connecting block and a spring column. The connecting block is rotatably connected to both sides of the support tube, and the fixed end of the spring column is fixed to the connecting block.

[0013] As a further embodiment of this utility model: the reinforcing component further includes a second U-shaped connector and a connecting shaft. The second U-shaped connector is fixed on both sides of the support tube, the connecting shaft is fixed inside the second U-shaped connector, and the connecting block is sleeved on the connecting shaft.

[0014] As a further embodiment of this utility model: the reinforcing component also includes a rubber block, which is fixed to the movable end of the spring column and fits against the side of the corrugated support plate.

[0015] The above technical solution involves installing the corrugated plate using the provided support components. The mounting holes on the mounting plate are aligned with the square through holes on the support pipe, and bolts are tightened. The first U-shaped connector is then fixed to the column. The support pipe is then installed, positioning the corrugated support plate and corrugated shock-absorbing pad on one side of the corrugated plate. The bolts in the mounting holes are tightened. This arrangement adds evenly arranged corrugated support plates to a longer corrugated plate, thereby increasing its strength, reducing deformation, and extending the lifespan of the corrugated guardrail.

[0016] By using the reinforced components, the second U-shaped connector is fixed to the upper and lower sides of the support tube and located behind the corrugated support plate. Pressing the rubber block compresses the spring column, and rotating the spring column causes the connecting block to rotate around the connecting shaft, moving the rubber block into the rear side of the corrugated support plate. Releasing the rubber block extends the spring column, pressing the rubber block against the corrugated support plate. This design increases the strength of the upper and lower ends of the corrugated support plate, while the spring column can absorb some of the impact. Attached Figure Description
