Combined steel box girder and construction method thereof
The invention relates to a combined steel box girder and a construction method thereof, the combined steel box girder comprises a plurality of longitudinal channel beams, the plurality of longitudinal channel beams are fixedly connected into a whole through inter-box cross beams, a plurality of transverse partition plates are arranged in the longitudinal channel beams at intervals in the longitudinal direction, and closed profiled steel sheets are laid on the longitudinal channel beams in the longitudinal direction. Cantilevers are arranged on the outer wall of the longitudinal groove-shaped beam located on the outer side in the longitudinal direction at intervals, and opening type profiled steel sheets are laid on the cantilevers in the longitudinal direction. The color plate production process is further optimized, and the color plate displays the visual effect of different colors when the environment temperature changes. The structural form of the bridge deck slab is optimized, the structural thickness and the self weight of the bridge deck slab are remarkably reduced, and meanwhile the durability of the bridge deck slab is remarkably improved.
本发明涉及一种组合钢箱梁及其施工方法，包括有数个纵向槽型梁，数个纵向槽型梁之间通过箱间横梁相固定连接为一体，纵向槽型梁内沿纵向间隔设置有数个横隔板，所述纵向槽型梁上沿纵向铺设有闭口型压型钢板，位于外侧的纵向槽型梁外壁沿纵向间隔设置有悬臂，悬臂上沿纵向铺设开口型压型钢板。本发明的彩板生产工艺进一步优化，彩板在环境温度变化时，显示不同颜色的视觉效果。本发明优化桥面板的结构形式，桥面板的结构厚度与自重显著降低，同时桥面板的耐久性也显著提升。
