Technical Field

[0001] The utility model belongs to the technical field of guardrail transition plates, and in particular relates to a transition plate between a double-layer double-wave recycling guardrail and a triple-wave guardrail. Background Art

[0002] Guardrail height plates are usually used for transition connections between different corrugated guardrails, such as the transition plates between double-wave guardrails and triple-wave guardrails, and the transition plates between triple-wave guardrails and quadruple-wave guardrails.

[0003] In the prior art, the Chinese utility model patent document with authorization announcement number CN212835143U discloses a new type of guardrail transition plate for highways, and specifically discloses a transition connection between a three-wave guardrail and a four-wave guardrail.

[0004] When transitioning between a double-layer double-wave guardrail and a triple-wave guardrail, the above-mentioned three-wave guardrail can be used to connect with the four-wave guardrail, but the four corrugated protrusions in the double-layer double-wave guardrail are required to correspond to the four corrugated protrusions of the transition plate. However, the vertical installation spacing of the two double-wave guardrails in the double-layer double-wave guardrail is usually different, which makes the above-mentioned transition plate less versatile and can only be customized according to different projects, which increases the cost of use.

[0005] Therefore, it is necessary to design a transition plate between a double-layer double-wave recycling guardrail and a triple-wave guardrail that can be adjusted to match different installation spacings to reduce costs to solve the current technical problems. Summary of the Invention

[0006] In response to the deficiencies in the prior art, the utility model provides a transition plate between a double-layer double-wave recycling guardrail and a triple-wave guardrail that can reduce costs by adjusting and matching a double-layer double-wave guardrail with different installation spacings.

[0009] The adjustable connecting hole is a waist-shaped hole opened on the connecting column along the vertical direction.

[0010] The stud is provided with a locking nut for locking or releasing the fixing nut and the stud.

[0011] A washer is sleeved on the outer side of the stud between the connecting column and the fixing nut.

[0012] The three-wave connecting section has three three-wave connecting section peaks, and the first double-wave connecting section has two first double-wave connecting section peaks. The two first double-wave connecting section peaks are respectively connected to the two three-wave connecting section peaks located below to form an integrated structure.
