高层建筑中采用劲性钢筋混凝土组合柱,可缩小柱的截面。但由于钢柱加工、现场上下柱的连接和钢柱节点中梁的钢筋须穿过腹板、异性箍筋、箍筋安装等工艺,给施工提出高难度的要求。结合工程实际,介绍劲性钢筋混凝土组合柱的施工过程。 High-rise buildings with rigid reinforced concrete composite columns, columns can be reduced cross-section. However, due to the steel column processing, the connection between the up and down columns on the site and the steel bars in the steel column nodes through the webs, the opposite sex stirrups and the stirrups are required to make the construction difficult. Combined with engineering practice, introduce the construction process of reinforced concrete composite column.
