Fabricated construction method of reinforced concrete column
The embodiment of the invention discloses a fabricated construction method of a reinforced concrete column. One specific implementation mode of the method comprises the steps that a prefabricated hollow column is manufactured, a semi-grouting sleeve is assembled at the upper end of a stress longitudinal bar of the prefabricated hollow column, and a vertical hole penetrating through the height direction is formed in the prefabricated hollow column in a vertical hole inner core occupying mode; a semi-grouting sleeve at the upper end of the lower-layer prefabricated hollow column extends into a horizontal post-pouring section at the bottom of the upper-layer prefabricated hollow column, a high-strength grouting material is poured through an upper opening of the semi-grouting sleeve, the upper-layer prefabricated hollow column is hoisted, and the lower end of a stress longitudinal bar of the upper-layer prefabricated hollow column is inserted into the semi-grouting sleeve to achieve grouting connection; and the horizontal post-pouring section and post-pouring concrete in the vertical hole are poured at the top of the vertical hole at the same time, and fabricated construction of the reinforced concrete column is completed. Bin sealing and pressure grouting operation of traditional sleeve grouting connection can be avoided, the prefabricated column hoisting speed is high, prefabricated column connection can be achieved by post-pouring concrete on site, the construction efficiency is high, the construction quality is easy to control, and the stress performance of the constructed column is good.
本公开的实施例公开了钢筋混凝土柱的装配式建造方法。该方法的一具体实施方式包括制作预制空心柱，在预制空心柱受力纵筋上端组装半灌浆套筒，采用竖孔内芯占位在预制空心柱中形成贯通高度方向的竖孔；下层预制空心柱上端的半灌浆套筒伸入上层预制空心柱底部的水平后浇段，经半灌浆套筒上部开口倒入高强灌浆料，吊装上层预制空心柱，上层预制空心柱受力纵筋下端插入半灌浆套筒内实现灌浆连接；经竖孔顶部同时浇筑水平后浇段及竖孔内的后浇混凝土，完成钢筋混凝土柱的装配式建造。本公开可避免传统套筒灌浆连接的封仓及压力灌浆作业，预制柱吊装速度快，现场后浇混凝土即可实现预制柱连接，施工效率高且施工质量易于管控，建造的柱受力性能好。
