Construction method of reinforced concrete composite beam cooperatively stressed with bridge girder erection machine
The invention discloses a construction method of a steel-concrete composite beam synergistically stressed with a bridge girder erection machine, which comprises the following steps of: (1) prefabricating a steel beam section, and constructing a bridge lower structure; (2) installing the bridge girder erection machine with a telescopic inclined support rod at the top at the position of a first hole pier; (3) connecting the steel beam section of the first hole with the inclined support rod; (5) a bridge girder erection machine is removed; (6) a second hole steel beam is constructed and connected with the first hole steel beam into a whole, and conversion from simple support to continuous is completed; (7) the bridge deck slab is installed, the wet joint in the midspan area and a pier top bottom plate are poured; (8) connection between an inclined supporting rod and the second hole steel beam is removed; and (9) the step (6) to the step (8) are repeated, and construction of other bridge openings of the whole bridge is completed. The method has the advantages of the conventional steel-concrete composite beam constructed with a bracket and without a bracket, the used equipment is simple, the operability is high, and the combined stress performance of the steel-concrete composite beam in the bridge forming stage can be fully exerted.
本发明公开了一种与架桥机协同受力的钢混组合梁施工方法，包括①预制钢梁节段，施工桥梁下部结构②在第一孔桥墩位置处安装顶部具有伸缩式斜撑杆的架桥机③将第一孔的钢梁节段与斜撑杆连接在一起，调整至设计高程后纵向连接④安装桥面板浇筑湿接缝⑤除架桥机⑥施工第二孔钢梁，并与第一孔钢梁连接为整体，完成“简支转连续”转换⑦安装桥面板浇注跨中区湿接缝与墩顶底板⑧解除斜撑杆与第二孔钢梁的连接，安装墩顶负弯矩区桥面板浇注墩顶负弯矩区湿接缝⑨重复步骤六至步骤八，完成整联桥梁其余桥孔的施工。本发明兼具传统有支架施工和无支架施工钢混组合梁的优点，所用设备简单、可操作性强，能够充分发挥成桥阶段钢混组合梁的组合受力性能。
