Description

Technical Field

[0001] The present application relates to the field of bridge construction design, and in particular to an anti-collision buffer bridge guardrail. Background Art

[0002] As an important part of bridge safety facilities, bridge guardrails are mainly used to prevent vehicles from going over the bridge and ensure driving safety. However, when existing bridge guardrails are impacted by vehicles, they often deform or break, which not only fails to effectively absorb the impact energy, but also may cause secondary damage to vehicles and passengers, and fail to ensure the safety of vehicles and passengers.

[0003] The existing utility model patent document with authorization announcement number CN218861332U discloses a bridge guardrail steel structure with an anti-collision structure, including a fixed base, wherein three fixed bases are provided, and support rods are fixedly installed on the tops of the three fixed bases, and fixed sleeves are provided at both ends of the tops of the three support rods, and a fixed plate is fixedly installed on one side of the fixed sleeve, and movable grooves are opened at both ends of the fixed plate on the side away from the support rods, and limiting rods are provided on the inner walls of the two movable grooves, and movable seats are provided on the outer sides of the two ends of the two limiting rods, and traction springs are provided between the four movable seats and the inner walls of the movable grooves, and traction plates are rotatably installed on the outer sides of the two movable seats at the same height, and a fixed seat is rotatably installed on the outer sides of the intersection of the two traction plates at the same height, and a guardrail plate is fixedly installed on the side of the two fixed seats away from the fixed plate.

[0004] When the guardrail board encounters an impact, the fixing seat provides support for the guardrail board. Since the fixing seat is installed in the middle part of the guardrail board, when the force point of the impact force is close to the two ends of the guardrail board, it is easy to cause the risk of breaking the connection between the guardrail board and the fixing seat, thereby reducing the protective ability of the guardrail.
