Combined bridge anti-collision guardrail stand column structure and installation method thereof
The invention provides a combined bridge anti-collision guardrail stand column structure which comprises upper steel plates and lower steel plates, wherein the multiple lower steel plates are embedded in an anti-collision guardrail lower component at intervals, the multiple upper steel plates are correspondingly connected and fixed to the lower steel plates, the upper surfaces of the upper steel plates are fixedly connected to the lower ends of stand column constructional columns, and the upper end of the stand column constructional column is fixed to the lower end of the outer sleeve; and multiple inner sleeves, wherein the two ends of each inner sleeve are arranged in the outer sleeve in a sleeved mode, the lower steel plate is provided with a plurality of lower steel plate preformed holes allowing the embedded screws to penetrate through, and the upper steel plate is correspondingly provided with a plurality of upper steel plate preformed holes allowing the upper ends of the embedded screws to extend out; therefore, the problem that the small-curvature-radius ramp bridge guardrail is difficult to install due to inaccurate positioning and angle deviation can be solved, meanwhile, the structure can be applied to road sections such as straight lines, circular curves and fitted curves, and the structure has the advantages of being large in application range and convenient to popularize.
一种组合式桥梁防撞护栏立柱结构及其安装方法，该结构包括上钢板和下钢板，所述下钢板为多块且间隔预埋于防撞护栏下部构件内，所述上钢板对应为多块且分别连接固定于下钢板，所述上钢板的上表面固定连接于立柱构造柱的下端，所述立柱构造柱的上端固定于外套管下端，以及多个内套管，所述内套管的两端分别套设于外套管内，所述下钢板设有多个供预埋螺杆贯穿的下钢板预留孔，所述上钢板对应设有多个供预埋螺杆的上端伸出的上钢板预留孔；由此，本发明不仅可以解决小曲率半径匝道桥梁护栏因定位不准和角度偏差造成的安装困难问题，同时可以在直线、圆曲线和拟合曲线等路段应用，具有适用范围大和便于推广的特点。
