Quick connecting structure between prefabricated pier column and base and construction method
The invention provides a quick connecting structure between a prefabricated pier column and a base and a construction method. The quick connecting structure comprises the prefabricated pier column and the base, a post-pouring groove and a connecting column are arranged at the upper part of the base, and concave-convex shear keys are arranged on the side walls of the post-pouring groove and the connecting column; the anti-shearing pin is arranged at the top of the connecting column, is positioned in the center of the connecting column and consists of an anti-shearing steel plate, an anti-shearing steel bar and concrete; the prefabricated pier column is composed of a pier column body, a pier column main rib and a shear-resistant pin groove, and the pier column main rib is pre-buried in the pier column body and penetrates out of the bottom of the pier column body. The pier column body and the connecting column are connected through the splicing seam, the pier column main rib extends into the post-pouring groove of the base, and a post-pouring belt is poured. The connecting structure is low in connecting precision requirement, large in construction allowable error, high in construction speed, easy in quality guarantee, simple in structure, low in cost and high in joint shear resistance, and quick connection between the prefabricated pier column and the base is achieved. Meanwhile, the cost is low, and engineering application and popularization are facilitated.
本发明提供一种预制墩柱与基座间快速连接结构及施工方法，快速连接结构包括预制墩柱和基座，在基座的上部设有后浇槽和连接柱，后浇槽和连接柱的侧壁上有凹凸型剪力键；抗剪销设置在连接柱顶部，位于连接柱中心，由抗剪钢板、抗剪钢筋和混凝土组成；预制墩柱由墩柱本体、墩柱主筋、抗剪销槽组成，墩柱本体内预埋有墩柱主筋，再将墩柱主筋从墩柱本体的底部穿出；通过拼接缝连接墩柱本体和连接柱，将墩柱主筋伸入至基座的后浇槽中，并浇筑后浇带。本发明连接构造连接精度要求低、施工容许误差大、施工速度快、质量易于保证、构造简单成本低、接缝抗剪能力强，实现了预制墩柱与基座间快速连接。同时成本低，有利于工程推广应用。
