Bridge concrete anti-collision guardrail vertical connection structure and strength calculation method thereof
The invention discloses a bridge concrete anti-collision guardrail vertical connection structure and a strength calculation method thereof. The bridge concrete anti-collision guardrail vertical connection structure comprises a prefabricated guardrail and a main beam. The prefabricated guardrail is arranged at the top of the main beam; fixing parts are arranged at the bottoms of the prefabricated guardrails, and the bottoms of the fixing parts are fixedly connected with the top ends of the outer side walls of the main beams; a plurality of first horizontal steel bars are arranged in the fixing part; the axis of the first horizontal steel bar is perpendicular to the axis of the prefabricated guardrail; guardrail prefabricated steel bars are arranged in the prefabricated guardrail in the vertical direction. One end of the bridge deck slab embedded steel bar is buckled on the first horizontal steel bar, and the end far away from the first horizontal steel bar extends into the main beam; the guardrail embedded steel bars are fixedly connected with the bridge deck slab embedded steel bars in a staggered buckling manner; according to the method, through reliable ideal analysis and calculation, a clear strength design value is provided, the problem that the vertical connection strength of the assembly type guardrail is blurred is solved, the method can be used for guiding vertical connection of the assembly type guardrail, and the reliability of vertical connection is guaranteed.
本发明公开了一种桥梁混凝土防撞护栏竖向连接结构及其强度计算方法，包括预制护栏和主梁；预制护栏设置在主梁的顶部；预制护栏的底部设置有固定部，固定部的底部与主梁的外侧壁顶端固定连接；固定部的内部设置有多条第一水平钢筋；第一水平钢筋的轴线与预制护栏的轴线垂直；沿预制护栏内部的竖直方向设置有护栏预制钢筋；桥面板预埋钢筋，一端搭扣在第一水平钢筋上，远离第一水平钢筋的一端延伸至主梁内部；护栏预埋钢筋，与桥面板预埋钢筋错位扣搭固定连接；本发明通过可靠的理想分析和计算，提出了明确的强度设计值，解决了装配式护栏竖向连接强度模糊不清的问题，可用于指导装配式护栏的竖向连接，保障了竖向连接的可靠性。
