Prefabricated erected steel-concrete composite beam and construction method
The construction method comprises the following steps: preparation for manufacturing the reinforced concrete composite beam: assembling a flange template; the flange formworks on the two sides and the steel tank beam are installed in an aligned mode; a panel bottom die is installed; pouring glue and sealing; installing reinforcing steel bars; pouring a concrete layer; performing maintenance; preparing for erecting the steel-concrete superposed beam, wherein the steps are as follows: reconditioning the steel-concrete superposed beam; hoisting the reinforced concrete superposed beam; feeding the reinforced concrete superposed beams; an erecting step of hoisting and arranging the reinforced concrete superposed beams by a bridge girder erection machine; beam falling; the steps are circulated until all erection construction is completed; compared with a traditional steel-concrete composite beam, the whole steel channel beam is manufactured and assembled in a factory, the steel channel beam does not need to be transported to the site in sections to be assembled, the assembling difficulty of the construction site is lowered, temporary building construction is reduced, and the construction period is shortened. The steel beams are integrally transported to the site to be poured and overlapped and then integrally erected, the transportation and installation difficulty and the construction cost are reduced, meanwhile, manual operation is reduced, input of beam erecting equipment is reduced, and the working efficiency is improved.
本发明公开一种预制架设钢混组合梁及施工方法，如以下步骤：制作钢混叠合梁准备、步骤如下：拼装翼缘模板；两侧翼缘模板与钢槽梁对齐安装；面板底模安装；灌胶密封；钢筋安装；混凝土层浇筑；养护；架设钢混叠合梁准备、步骤如下：钢混叠合梁整备；钢混叠合梁运吊；钢混叠合梁喂梁；架桥机吊运排列钢混叠合梁的架设步骤；落梁；循环上述步骤直至完成全部架设施工；本发明与传统钢混组合梁相比，钢槽梁整体在工厂制造拼装，无需再分节段运至现场拼装，降低施工现场拼装难度，减少临建施工，节省工期。钢梁整体运至现场进行浇筑叠合，再整体架设，减少运输安装的难度以及施工成本，同时减少人工作业，减少架梁设备的投入，提高工作效率。
