Prefabricated middle cross beam of concrete-filled steel tube tied arch bridge and construction method
The invention relates to a prefabricated middle cross beam of a concrete-filled steel tube tied arch bridge and a construction method. The prefabricated middle cross beam comprises a bailey beam suspension support system and a floating crane installation balance arch rib horizontal thrust system. The bailey beam suspension support system comprises two bailey beam supporting frames, a movable track is arranged between the two bailey beam supporting frames, and two sets of bailey beam suspension supports are hoisted below the movable track. The method has the advantages that the Bailey beam suspension support system is adopted and comprises the middle cross beam segment beam suspension support installation structure and the middle cross beam post-cast strip suspension formwork system, a large amount of support cost can be saved, interference to under-bridge operation is reduced, middle cross beam segment beam prefabrication and post-cast strip cast-in-place are combined, and the construction speed is high.
本发明涉及一种钢管混凝土系杆拱桥预制中横梁及施工方法，包括贝雷梁悬挂支架体系和浮吊安装平衡拱肋水平推力体系；贝雷梁悬挂支架体系包括贝雷梁支撑架，两个贝雷梁支撑架之间设置有可移动式轨道，可移动式轨道下方吊装有两组贝雷梁悬挂支架。本发明的有益效果是：采用贝雷梁悬挂支架体系，包括中横梁节段梁悬挂支架安装结构和中横梁后浇带悬挂模板体系，可节约大量支架成本，减少了对桥下作业的干扰，通过中横梁节段梁预制与现场浇筑后浇带相结合，施工速度快。
