Prefabricated bridge pier connected by self-locking large-diameter steel bars and construction method of prefabricated bridge pier
A prefabricated pier connected by self-locking type large-diameter steel bars comprises a bearing platform, a prefabricated pier body, a prefabricated cover beam, common steel bars, grouting materials, self-locking type anchorage devices, the large-diameter steel bars, steel base plates, nuts and corrugated pipes. Corrugated pipes are arranged in the bearing platform, the prefabricated pier body and the prefabricated cover beam, and self-locking anchorage devices are further embedded in the positions, below the corrugated pipes, in the bearing platform; the steel base plate is arranged at the lower end of the large-diameter steel bar and penetrates through the self-locking anchorage device to anchor the lower end of the large-diameter steel bar, the large-diameter steel bar penetrates through corrugated pipes in the bearing platform, the prefabricated pier body and the prefabricated cover beam to connect the bearing platform, the prefabricated pier body and the prefabricated cover beam, and the upper end of the large-diameter steel bar is connected with a nut to anchor the upper end of the large-diameter steel bar. The invention further relates to a construction method of the prefabricated pier connected through the self-locking type large-diameter steel bars. Large-diameter steel bars penetrate through the whole bridge pier structure, a bearing platform, a pier column and a cover beam which are independently manufactured are connected into a system, and the purpose of overall stress is achieved.
一种自锁式大直径钢筋连接的预制桥墩，包括承台、预制墩身、预制盖梁、普通钢筋、灌浆料、自锁式锚具、大直径钢筋、钢垫板、螺帽、波纹管；承台、预制墩身和预制盖梁内均设置波纹管，承台内波纹管的下方还埋设自锁式锚具；钢垫板设置在大直径钢筋的下端，钢垫板穿过自锁式锚具从而将大直径钢筋的下端锚固，大直径钢筋穿过承台、预制墩身、预制盖梁内的波纹管将承台、预制墩身和预制盖梁连接，大直径钢筋的上端连接螺帽从而将大直径钢筋的上端锚固。还涉及一种自锁式大直径钢筋连接的预制桥墩的施工方法。本发明采用大直径钢筋贯穿整个桥墩结构，将独立制作的承台、墩柱和盖梁连成一个系统，达到整体受力的目的，属于桥梁工程技术领域。
