The invention discloses a fabricated concrete prefabricated column and a construction method thereof. The construction method of the fabricated concrete prefabricated column comprises the steps that longitudinal bars are arranged, and spiral stirrups are bound or welded outside the longitudinal bars to form a reinforcement cage; the reinforcement cage is sleeved with hoop plates, and the reinforcement cage and the hoop plates are connected; formwork erecting and concrete pouring are conducted to form the prefabricated column; an upper prefabricated column body of the prefabricated column is hoisted to the position over a lower prefabricated column body of the prefabricated column; and the hoop plates of the upper prefabricated column body and the hoop plates of the lower prefabricated column body are welded and connected. The reinforcement cage formed by welding the longitudinal bars and the spiral stirrups serves as a framework of the prefabricated column, and the axial bearing capacity, the bending resistance bearing capacity and the shearing resistance bearing capacity of the prefabricated column are effectively guaranteed; and the prefabricated column can be prefabricated and produced in a factory and other places, only hoisting butt joint and welding connection of the upper prefabricated column body and the lower prefabricated column body are conducted on a construction site, the number of procedures is small, the construction difficulty is low, and the construction efficiency is high.
本发明公开了一种装配式混凝土预制柱及其施工方法，装配式混凝土预制柱施工方法包括：布置纵筋并在纵筋外绑扎或焊接螺旋箍筋，形成钢筋笼；在钢筋笼外套设箍板，并连接钢筋笼与箍板；支模并浇筑混凝土，使预制柱成型；吊装预制柱的预制柱上柱至预制柱的预制柱下柱正上方；焊接连接预制柱上柱的箍板与预制柱下柱的箍板。利用纵筋和螺旋箍筋焊接形成的钢筋笼作为预制柱的骨架，有效地保障了预制柱的轴向承载力、抗弯承载力和抗剪承载力；预制柱可在工厂等处预制生产，在施工现场仅进行预制柱上柱与预制柱下柱的吊装对接和焊接连接，工序少、施工难度低且施工效率高。
