Abstract: Combination components of steel pipe column and concrete are usually connected by bolts,which has much obvious defects,such as heavy welding workload,difficult construction,uncoordinated deformation and obvious influence of welding residual stress on subsequent quality. According to the existing research results and project design drawings,steel ring and ring reinforced concrete beam are added to the outer wall of steel pipe column. The steel pipe column is connected with the ring beam through the steel ring,and other concrete components are connected with the steel pipe column through the ring beam. Compared with the traditional process,the traditional shear bolts are replaced by the steel ring,which has the advantages of simple construction,less welding,and can avoid the shortcomings of the traditional process. The ring beam is used as the transition component between the steel pipe column and the concrete to solve the arrangement problem of the beam column joint reinforcement. The construction technology is discussed and summarized in the paper,and the key technologies for the processing and installation of steel pipe column and ring beam are discussed in detail.
