Wide steel-concrete composite beam and construction method thereof
The invention discloses a wide steel-concrete composite beam which comprises a core steel beam arranged on a lower structure of a bridge. The cantilever steel beams are arranged on two sides of the core steel beam; the bridge deck slab comprises a core bridge deck slab and a cantilever bridge deck slab which are connected through a wet joint. During construction, a bridge substructure is constructed, and a first hole core steel beam is erected through a bridge girder erection machine; core bridge deck slabs are installed, core steel beams are temporarily lifted, then wet joint concrete is poured between the adjacent core bridge deck slabs, and then a bridge girder erection machine passes through holes; cantilever steel beams are installed on the two sides of the core steel beam through a crane, cantilever bridge deck slabs are installed on the cantilever steel beams, then wet joint concrete is poured, and erection of a first hole combination beam is completed; and according to the steps, the composite beam is erected hole by hole until construction of the whole bridge is completed. The structure is simple, stress is reasonable, safety and stability are achieved, the split erecting mode is adopted, the construction cost is saved, and the construction difficulty is lowered.
本发明公开了一种宽幅钢混组合梁，包括：核心钢梁，设置在桥梁下部结构上；悬臂钢梁，设置在核心钢梁两侧；桥面板，包括由湿接缝相连的核心桥面板和悬臂桥面板。施工时，施工桥梁下部结构，采用架桥机架设第一孔核心钢梁；安装核心桥面板，并对核心钢梁进行临时提拉，然后在相邻核心桥面板之间浇筑湿接缝混凝土，之后使架桥机过孔；采用吊机在核心钢梁两侧安装悬臂钢梁，并在悬臂钢梁上安装悬臂桥面板，之后浇筑湿接缝混凝土，完成第一孔组合梁架设；按照上述步骤，逐孔进行组合梁的架设，直至完成整座桥梁的施工。本发明构造简单，受力合理，安全稳定，采用分部分架设的方式，省了施工成本，降低了施工难度。
