Construction method for assembly joints in assembly type reinforced concrete frame column
The invention discloses a construction method for an in-column assembly joint of an assembly type reinforced concrete frame column, and belongs to the technical field of assembly type constructions.The method comprises the steps that an upper prefabricated column and a lower prefabricated column are hoisted and positioned; under the support of the adjustable lateral support unit, welding the upper and lower steel pipes, and performing sleeve grouting connection on the upper and lower steel bars; assembling node shaping templates in the mounting columns on the outer sides of the upper and lower steel bars; concrete is poured into the column middle assembly joint shaping formwork and the upper and lower steel pipes to form a reinforced concrete frame column; and concrete is cured, and after the concrete is finally set, upper-layer construction is conducted on the reinforced concrete frame columns on the current layer within the early age of the concrete. The assembly joint is arranged in the column with the small column bending moment, the early-age bearing performance of the column assembly joint is improved through the steel pipe concrete restraining effect, the formwork supporting system with rigidity is applied to transmit construction loads to the prefabricated part, the early-age load bearing capacity is greatly improved, and rapid assembly is achieved.
本发明公开了一种装配式钢筋混凝土框架柱柱中装配节点施工方法，属于装配式建筑技术领域，方法包括：对预制上柱和预制下柱进行吊装、定位；在可调节侧向支撑单元的支撑下，焊接上、下钢管，对上、下钢筋进行套筒灌浆连接；在上、下钢筋的外侧安装柱中装配节点定型模板；向柱中装配节点定型模板内、上、下钢管内浇筑混凝土，形成钢筋混凝土框架柱；养护混凝土，当混凝土终凝后，在混凝土的早龄期内，在当前层钢筋混凝土框架柱上，进行上层施工。将装配节点设在柱弯矩较小的柱中位置，采用钢管混凝土约束效应提高柱装配节点早龄期承载性能，并应用带刚度的模板支撑体系传递施工荷载至预制构件上，大大提高早龄期受荷承载能力，实现快速装配。
