Upright column structure suitable for large-span deck type steel truss arch bridge
The invention relates to the technical field of bridges, in particular to an on-arch stand column structure suitable for a large-span deck type steel truss arch bridge, which comprises a stand column and a longitudinal inclined strut, the stand column is arranged on a main arch, the longitudinal inclined strut is arranged on the stand column, one end of the longitudinal inclined strut is connected with the side face of the stand column, and the other end of the longitudinal inclined strut is connected with a top plate of the main arch. According to the on-arch stand column structure suitable for the large-span deck type steel truss arch bridge, the longitudinal inclined strut is arranged on one side of the stand column, one end of the longitudinal inclined strut is connected with the side face of the stand column, and the other end of the longitudinal inclined strut is connected with the top plate of the main arch, so that the longitudinal slenderness ratio of the stand column and the longitudinal bending moment of the column bottom can be greatly reduced; the longitudinal anti-pushing rigidity and the longitudinal stability of the stand column are remarkably improved, the stress safety of construction and operation can be better met, and meanwhile the material consumption can be saved.
本发明涉及桥梁技术领域，具体涉及一种适用于大跨度上承式钢桁架拱桥的拱上立柱结构，包括立柱和纵向斜撑，立柱设置在主拱上，立柱上设置有纵向斜撑，纵向斜撑的一端连接立柱的侧面，另一端连接主拱的顶板。该适用于大跨度上承式钢桁架拱桥的拱上立柱结构，通过在立柱的一侧设置纵向斜撑，纵向斜撑的一端连接立柱的侧面，另一端连接主拱的顶板，能够大幅减小立柱的纵向长细比及柱底纵向弯矩，显著提高立柱的纵向抗推刚度及纵向稳定性，能更好的满足施工及运营的受力安全，同时可以节省材料用量。
