Railway lattice type on-arch stand column
The invention relates to a railway lattice type on-arch stand column which is a lattice type stand column composed of a plurality of steel pipes and is vertically arranged above a main arch ring at intervals in the longitudinal bridge direction. The bottoms of the on-arch stand column is fixed to the top of the main arch ring through a concrete joint, and the top of the on-arch stand column supports a main beam. In the construction process, the lattice type stand column is vertically segmented, each segment is welded in a factory or a construction site, then segmented hoisting and positioning are carried out, flange plates are used for connection in the construction site, and finally the lattice type on-arch stand column is formed. The structure is simple, especially for a large-span high stand column structure, the stand column is large in rigidity, light in self weight, small in stress influence on the main arch ring, good in anti-seismic performance, reasonable in stress, easy to manufacture, easy and convenient to construct, good in economical efficiency and capable of well meeting the requirements for comfort and safety when a railway train runs.
本发明涉及铁路格构式拱上立柱，所述拱上立柱为众多钢管组成的格构型立柱，在主拱圈上方沿纵桥向间隔竖向布置；拱上立柱底部通过混凝土节点固定到主拱圈的顶部，拱上立柱顶部支撑主梁。本发明施工时将格构式立柱竖向分段，每段在工厂或工地焊接好，然后分段起吊，定位，在工地现场利用法兰盘连接，最后形成格构式拱上立柱；结构构造简单，特别对于大跨高立柱的结构，立柱刚度大、自重轻，对主拱圈受力影响小，抗震性能好，受力合理，制造简洁，施工简便，经济性好，能很好的满足铁路列车行车时的舒适性和安全性要求。
