Construction method of prefabricated corrugated steel web bent cap
The invention discloses a construction method for manufacturing a corrugated steel web cover beam. The construction method comprises the steps that corrugated steel webs are machined, and partition plates and connecting structures are welded; binding the bottom plate reinforcement cage and the top plate reinforcement cage, and mounting prestressed tendons; a cover beam bottom formwork is installed on the prefabricated pedestal, transverse side formworks of the cover beam top plate and the cover beam bottom plate are positioned, and the transverse side formworks are installed; and layered pouring and maintenance are conducted, the prestressed tendons are tensioned at a time, and the side formworks are dismantled. The corrugated steel web is adopted, the upper flange and the lower flange of the corrugated steel web are welded to the shear keys embedded in the top plate and the bottom plate respectively, the upper edge and the lower edge of the partition plate are welded to the shear keys embedded in the top plate and the bottom plate respectively, and the two vertical edges of the partition plate are welded to the corrugated steel web respectively. The structural strength of the corrugated steel web bent cap is ensured, and the weight of the bent cap is reduced on the premise that the structural strength meets the design requirement.
本发明公开了一种制波形钢腹板盖梁的施工方法，包括：加工波形钢腹板，焊接隔板和连接结构；绑扎底板钢筋骨架和顶板钢筋骨架，安装预应力筋；在预制台座上安装盖梁底模板，定位出盖梁顶板和盖梁底板的横向侧模板，安装横向侧模板；分层浇筑，养护，一次张拉预应力筋，拆除侧模板。本发明采用波形钢腹板，波形钢腹板的上翼缘和下翼缘分别与预埋在顶板和底板内的剪力键焊接在一起，隔板的上缘和下缘分别与预埋在顶板和底板上的剪力键焊接在一起，且隔板的两竖缘分别与波形钢腹板焊接在一起，确保波形钢腹板盖梁的结构强度，在保证结构强度满足设计要求的前提下减轻盖梁的重量。
