Anti-collision guardrail and construction method thereof
The invention discloses an anti-collision guardrail, and belongs to the technical field of bridge engineering. The anti-collision guardrail comprises a guardrail body, a bridge deck and a connecting structure. A multi-step structure is arranged on the upper surface of the bridge deck slab, a plurality of connecting structures are embedded in the step face of the connecting step at intervals, and the lower end face of the guardrail is matched with the multi-step structure of the bridge deck slab and connected with the multi-step structure of the bridge deck slab through the connecting structures. The connecting structure comprises a screw rod, a sleeve and an eccentric nut, and the sleeve is vertically embedded in the step surface of the connecting step; the lower end of the screw penetrates through and is connected to the bottom closed end of the sleeve, and the upper end of the screw penetrates through the lower end face of the guardrail and is fixedly connected with the guardrail. In the device, the guardrails and the bridge deck are connected through multi-step matching and connecting structures, so that the connecting strength of the guardrails and the bridge deck is ensured, and the shear capacity is improved; the sleeve and the eccentric nut reduce the requirement for the precision of the embedded part, and the controllability of the installation precision is improved. The whole device is simple in process, high in applicability, wide in application and low in manufacturing cost.
本发明公开了一种防撞护栏，属于桥梁工程技术领域。所述防撞护栏包括：护栏、桥面板和连接结构；桥面板上表面设有多级阶梯结构，连接阶梯的阶梯面上间隔镶嵌有多个连接结构，护栏下端面与桥面板的多级阶梯结构相配合，并通过连接结构进行连接；连接结构包括螺杆、套筒和偏心螺母，套筒竖直预埋在连接阶梯的阶梯面内；螺杆的下端穿过并连接在套筒的底部封闭端，螺杆的上端穿过护栏下端面并与护栏固定连接；在本装置中，护栏与桥面板通过多级阶梯配合和连接结构连接，确保了护栏与桥面板的连接强度，提高了抗剪能力；套筒和偏心螺母降低了对预埋件精度的要求，提高了安装精度的可控性。整个装置工艺简单、适用性强、用途广、造价低。
