U-shaped steel-wrapped energy-absorbing concrete guardrail structure with studs
The invention belongs to the technical field of highways, and discloses a U-shaped steel externally-wrapped energy-absorbing concrete guardrail structure with studs and a method, and the U-shaped steel externally-wrapped energy-absorbing concrete guardrail structure comprises a guardrail main body with a groove, an anti-collision foamed aluminum plate, U-shaped steel externally wrapped, the studs and triangular steel. And when the guardrail main body is poured, the studs are simultaneously poured in the guardrail main body and are welded with the externally-wrapped U-shaped steel to form a whole. The anti-collision closed-cell foamed aluminum plate is embedded into a main body groove to absorb first-time collision force, and then the force is transmitted to a concrete main body. Key tooth structures and anchoring connecting parts are arranged at the bottoms of the guardrails, triangular steel is pre-embedded in the lower portion, and the structural stability is enhanced. According to the design, the energy absorption capacity of the guardrail is improved, the safety of passengers is guaranteed, and the guardrail is suitable for high-risk road sections.
本发明属于公路技术领域，公开了一种带栓钉的外包U型钢吸能混凝土护栏结构及方法，包括带凹槽的护栏主体、防撞泡沫铝板、外包U型钢、栓钉及三角钢。在护栏主体浇筑时，栓钉同时浇筑于内部，与外包U型钢焊接形成整体。防撞闭孔泡沫铝板嵌入主体凹槽，吸收首次撞击力，随后力量传递至混凝土主体。护栏底部设有键齿构造和锚固连接部件，三角钢预埋于下部，增强结构稳定性。此设计提升了护栏的能量吸收能力，保障车乘人员安全，适用于高风险路段。
