Middle straining beam connection construction method of fabricated pier column
The invention provides a middle straining beam connection construction method of an assembly type pier column, which comprises the following steps: pouring lower pier columns on two sides, after the lower pier columns are hardened, hoisting a prefabricated middle straining beam between the lower pier columns on the two sides, erecting a connecting bracket, hoisting an upper pier column to the upper part of the connecting bracket, and connecting the upper pier column with the prefabricated middle straining beam. Straining beam reinforcing steel bars are poured in the prefabricated middle straining beam in the length direction of the prefabricated middle straining beam in advance, the straining beam reinforcing steel bars are composed of vertical face main reinforcing steel bars distributed in a U-shaped mode and flat face main reinforcing steel bars arranged in a laid mode, and openings of the vertical face main reinforcing steel bars distributed in the U-shaped mode face upwards. Compared with a traditional technical scheme, the method has the advantages that the weight of the prefabricated middle straining beam during assembly is greatly reduced, transportation and hoisting are facilitated, the connection mode between the upper pier column and the lower pier column and the prefabricated middle straining beam is improved, upper and lower stress between the upper pier column and the lower pier column is reliable, exposed steel bars are connected through winding steel bars of a spiral structure, and the construction efficiency is improved. And the shear resistance is further improved, so that the shear resistance and the anti-seismic property of the prefabricated middle straining beam are stably improved.
本发明提供了一种装配式墩柱的中系梁连接施工方法，包括以下步骤：浇筑两侧的下墩柱，待下墩柱硬化后，吊装预制中系梁至两侧的下墩柱之间，架设连接支架，并吊装上墩柱至连接支架的上方，预制中系梁预先在其内部沿其长度方向浇筑有系梁钢筋，系梁钢筋由U形分布的立面主筋和平铺排列的平面主筋组成，U形分布的立面主筋的开口朝上。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预制中系梁的重量，便于运输、吊装，改善了上、下墩柱以及预制中系梁之间的连接方式，上墩柱与下墩柱之间上、下受力可靠，并通过螺旋结构的缠绕钢筋连接外露钢筋，进一步增加抗剪能力，使预制中系梁的抗剪切性能以及抗震性能得到稳定提升。
