Description
Technical Field
[0001] The utility model relates to the technical field of bridge guardrail design, in particular to a bridge support guardrail with a buffer structure. Background Art
[0002] A support guardrail is a structure used to protect the safety of a site or area. It is usually installed on the edge or in a dangerous location to prevent people from accidentally entering or falling. Support guardrails are usually made of metal, wood or other solid materials and can be fixed to the ground or on the wall. They are commonly found in public places, construction sites, road traffic, bridges and other places. They restrict people from entering dangerous areas and provide boundaries or limits. The design and specifications of support guardrails vary depending on their use, but they are all intended to provide safety protection. A bridge support guardrail with a buffer structure refers to a buffer device added to an ordinary support guardrail to increase the protection effect in the event of an accident.
[0003] Current bridge support guardrails with buffer structures generally use materials that can absorb and disperse impact forces, such as compressible polymers, rubber or foam. These materials can effectively reduce the impact force borne by vehicles and passengers when an accident occurs, thereby reducing the risk of injury. Existing bridge support guardrails with buffer structures cushion vehicles by installing rubber on the guardrails. However, if the driver answers a phone call or drives tired while driving, especially in foggy weather, the driver's control of the direction is not so accurate. During slow driving, the vehicle may hit the guardrail. Since existing guardrails are generally cushioned by compressible polymers, rubber or foam, the cushioning effect is not good.
