钢筋混凝土(RC)环梁是一种钢筋混凝土梁和钢管混凝土柱的连接构件,已被成功应用于部分高层及超高层建筑中。通过对钢管混凝土柱-RC环梁的施工成果进行总结,并结合南宁市九洲国际工程实践,详细介绍了钢管混凝土柱-RC环梁节点的施工关键技术。实践证明,该施工工艺流程有效可行,且具有良好的社会与经济效益。
Reinforced concrete (RC) ring beam is a kind of connecting member of reinforced concrete beam and concrete filled steel tube column, which has been successfully used in some high-rise and super-tall buildings. Through summarizing the construction results of CFST-RC ring beam and combining with the international engineering practice of Jiuzhou in Nanning City, the key construction technology of CFST-RC ring beam node is introduced in detail. Practice has proved that the construction process is feasible and effective, and has good social and economic benefits.
