Technical Field
[0001] The utility model relates to the technical field of highway bridges, in particular to a guardrail for highway bridges. Background Art
[0002] Highway bridges are one of the necessary factors for rapid economic development. When building or repairing highway bridges, temporary guardrails are needed to separate vehicles and warn passing vehicles to make reasonable avoidance, thus ensuring the safety of staff and passengers.
[0003] However, most of the guardrails for highway bridges are usually spliced together by bolts or wires, which leads to low installation efficiency of the guardrails. In addition, the vertical bars on the guardrails are all welded and fixed. Therefore, when one of the vertical bars is damaged, the entire guardrail needs to be replaced, which is not practical enough. Therefore, we propose a guardrail for highway bridges to solve the above problems. Utility Model Content
