Bridge assembly type anti-collision guardrail
The bridge assembly type anti-collision guardrail comprises a bridge prefabricated slab and a guardrail body, a buffer groove is formed in the front end of the guardrail body, and the guardrail body is fixedly connected with the bridge prefabricated slab; the buffering mechanism comprises a buffering roller and a force unloading piece, the buffering roller is located in the buffering groove and rotationally connected with the buffering groove, the force unloading piece is arranged on the side, away from the buffering groove, of the guardrail, one end of the buffering roller penetrates through the guardrail to be fixedly connected with the force unloading piece, and the force unloading piece is slidably connected with the guardrail through the buffering roller; the supporting mechanism comprises a supporting plate and a conduction assembly, the supporting plate is fixedly connected to the side, away from the buffer groove, of the guardrail, the conduction assembly is arranged at the bottom end of the supporting plate, a grouting hole is formed in the supporting plate, the supporting plate communicates with the conduction assembly, and the conduction assembly abuts against the guardrail. According to the assembly type guardrail, the effect of effectively buffering the external force caused by vehicle collision can be achieved, the assembly type guardrail structure is protected, the service life of the guardrail is prolonged, and the use cost of the whole assembly type guardrail is reduced.
本发明公开一种桥梁装配式防撞护栏，包括桥梁预制板，护栏，护栏前端开设有缓冲槽，护栏与桥梁预制板固接；缓冲机构，包括缓冲辊和卸力件，缓冲辊位于缓冲槽内与缓冲槽转动连接，卸力件设置在护栏远离缓冲槽的一侧，缓冲辊的一端贯穿护栏与卸力件固接，卸力件通过缓冲辊与护栏滑动连接；支撑机构，包括支撑板和传导组件，支撑板固接在护栏远离缓冲槽的一侧，传导组件设置在支撑板的底端，支撑板内开设有灌浆孔，支撑板与传导组件连通，传导组件与护栏抵接。本发明能够实现有效缓冲车辆撞击带来的外力作用，并且对装配式的护栏结构提供保护，提高护栏的使用寿命，降低整体装配式护栏的使用成本。
