Description

Technical Field

[0001] The utility model belongs to the technical field of bridge deck protection, and in particular relates to a bridge deck protection device which is easy to install and fix. Background Art

[0002] Bridge guardrails are safety features installed on both sides of bridges. Their primary purpose is to prevent uncontrolled vehicles from running off the bridge deck, protecting pedestrians and vehicles. They are typically made of metal, concrete, or other weather-resistant materials, possessing sufficient strength and toughness to withstand impact forces. Bridge guardrails are typically designed to comply with relevant safety standards to effectively minimize damage and injury in the event of a traffic accident. Furthermore, they offer aesthetic appeal, blending seamlessly with the overall design of the bridge.

[0003] The bridge deck guardrail is an important component of the bridge, and its main function is to ensure the safety of pedestrians and vehicles. It can effectively prevent out-of-control vehicles from rushing out of the bridge deck, protect the bridge from accidental collisions, and prevent pedestrians from falling. In addition, the bridge deck guardrail also has the function of beautifying the bridge and coordinating the surrounding environment. Through different design styles and materials, the overall visual effect of the bridge can be improved, and the cultural connotation and artistic sense of the bridge can be enhanced. In modern bridge construction, the design and construction quality of the guardrail are directly related to the safety and service life of the bridge. The problem with the above technology is that in the process of assembling the bridge deck guardrail, columns are needed to support and fix the guardrail. However, when assembling the columns and guardrail, they need to be assembled and fixed through multiple connectors and fixings, which requires users to spend a long time and energy, thereby reducing the assembly convenience of the guardrail and making it inconvenient for users to use.
