Connection construction method of fabricated pier column
The invention provides an assembly type pier column connection construction method which comprises the steps that pier column sections are prefabricated, a pier column is divided into a plurality of sections to be prefabricated in a prefabricating field, the height of the multiple sections after the multiple sections are supported and stacked together through a mounting support is the same as the design height of the pier column, and then the prefabricated pier column sections are transported to a construction field. And hoisting the lower pier column, the mounting bracket and the upper pier column to a pier foundation which is measured in advance, and mounting the lower pier column, the mounting bracket and the upper pier column. Compared with a traditional technical scheme, the method has the advantages that the weight of the pier column during assembly is greatly reduced, and the method is convenient to transport and hoist and is convenient to popularize and apply in mountainous areas and areas with inconvenient traffic; meanwhile, the connection mode between the pier column sections is improved, the upper pier column and the lower pier column are reliably stressed, the upper pier column section and the lower pier column section are connected through the installation support, the exposed steel bars are connected through the winding steel bars of the spiral structure, and the shear capacity can be improved through the matching of the installation grooves and the vertical rods. And the anti-shearing performance and the anti-seismic performance of the prefabricated pier column are stably improved.
本发明提供了一种装配式墩柱的连接施工方法，包括预制墩柱节段，将墩柱分为多个节段在预制场内预制，多个节段通过安装支架支撑堆垛在一起后的高度与墩柱设计高度相同，然后运输预制墩柱节段至施工场地，将下墩柱、安装支架以及上墩柱吊装至事先测定好的墩基处并安装。相较于传统技术方案，本方法的优点在于大幅降低了装配时墩柱的重量，便于运输、吊装，便于在山区及交通不便区域推广应用；同时，改善了墩柱节段之间的连接方式，由于上、下墩柱受力可靠，上下墩柱节段间采用安装支架连接，并通过螺旋结构的缠绕钢筋连接外露钢筋，安装槽与竖杆的契合也能增加抗剪能力，使预制装配式墩柱的抗剪切性能以及抗震性能得到稳定提升。
