Transition connection structure of metal beam column type guardrail and concrete guardrail
The invention provides a metal beam column type guardrail and concrete guardrail transition connection structure which comprises a concrete guardrail and a metal guardrail, the concrete guardrail is connected with the metal guardrail through the transition connection structure, and the metal guardrail comprises a stand column and a cross beam; the transition connecting structure comprises a transition wall, a connecting wall and a connecting beam, the transition wall and the connecting wall are both concrete walls, one end of the transition wall extends to the concrete guardrail, the other end of the transition wall is connected with the connecting wall, a gap is formed between the connecting wall and the metal guardrail, and a plurality of horizontal outer sleeves are fixedly arranged on the connecting wall; one end of the connecting beam extends into the outer sleeve, a gap is formed between the connecting beam and the outer sleeve, and the other end of the connecting beam extends into the cross beam and is fixedly connected with the cross beam. According to the transition connecting structure, the connecting beam, the transition wall and the connecting wall are adopted, smooth transition between the concrete guardrail and the metal guardrail is achieved, the connecting beam made of the metal material has high strength, the large bearing capacity is achieved when a vehicle collides, and the vehicle can be prevented from falling off a bridge.
本发明提供了一种金属梁柱式护栏与混凝土护栏过渡连接结构，包括混凝土护栏和金属护栏，混凝土护栏通过过渡连接结构与金属护栏相连，金属护栏包括立柱和横梁；过渡连接结构包括过渡墙、连接墙和连接梁，过渡墙和连接墙均为混凝土墙，过渡墙的一端延伸至混凝土护栏，另一端与连接墙相连，连接墙与金属护栏之间具有间距，所述连接墙上固定设置有多根水平的外套管；连接梁的一端伸入外套管，且连接梁与外套管之间具有间隙，连接梁的另一端伸入横梁并与横梁固定连接。本发明的过渡连接结构采用连接梁、过渡墙和连接墙，实现了混凝土护栏和金属护栏的平缓过渡，且金属材质的连接梁具有较高的强度，当车辆撞击时具有较大的承受能力，可防止车辆坠桥。
