Prefabricating construction method for box girders in girder yard
The invention provides a box girder prefabrication construction method for a girder yard. The box girder prefabrication construction method comprises the steps that S1, after construction preparation is completed, manufactured bottom formworks, side formworks, end formworks and inner formworks are conveyed to a site; the method comprises the following steps of S1, arranging a side mold on a template, S2, fixing a bottom mold on a pedestal foundation of a beam making pedestal, and fixedly connecting the lower edge of the side mold with the bottom mold, S3, binding and forming a steel reinforcement framework on a mold, hoisting the steel reinforcement framework into the mold after binding and forming, adjusting the steel reinforcement framework to a preset position in the template, and then sliding an inner mold into the template and fixing the inner mold through a bracket; s4, after the steel reinforcement framework and the formwork are installed in place, beam body concrete pouring is conducted, pouring is conducted from the end of a box beam bottom plate, then a web plate is poured, and finally a top plate is poured; the concrete pouring sequence is controlled, pouring is started from the end of a bottom plate of the box girder, then a web plate is poured, a top plate is poured at the rearmost portion, and synchronous pouring is conducted on the two sides of the box girder, the high construction efficiency is achieved, meanwhile, the concrete deformation and position deviation are reduced, and the construction quality is guaranteed.
本发明提供一种梁场箱梁预制施工方法,包括:步骤S1,施工准备完成后将制作完成的底模、侧模、端模、内模运送至现场;步骤S2,将底模固定在制梁台座的台座基础上,将侧模下缘与底模之间固定连接,步骤S3,将钢筋骨架在胎具上绑扎成型,绑扎成型后吊装入模,并在模板内调整至预定位置,然后将内膜滑入并通过托架固定;步骤S4,钢筋骨架及模板安装就位后进行梁体砼浇筑,自箱梁底板端头开始浇筑,再浇筑腹板,最后方浇筑顶板;控制混凝土的浇筑顺序,自箱梁底板端头开始浇筑,再浇筑腹板,最后方浇筑顶板,箱梁两侧同步浇注,具有较高的施工效率的同时,降低混凝土变形量以及位置偏差,保障了施工质量。
