摘要
A joint of a concrete-filled steel tube column and an annular steel plate concrete beam, comprising a concrete-filled steel tube column (1), an annular steel plate concrete beam (2), and a reinforced concrete frame beam (3). The annular steel plate concrete beam (2) comprises a steel plate (8) and a steel reinforced cage; concrete slurry passage holes (12) are formed in the middle of the steel plate (8); the steel plate (8) and the steel reinforced cage are annular, the annular steel plate (8) and the steel reinforced cage is coaxially arranged; the annular steel plate concrete beam (2) is sleeved on the outer side wall of the concrete-filled steel tube column (1); one end of the reinforced concrete frame beam (3) extends into the annular steel plate concrete beam (2); stressed steel bars (11) of the reinforced concrete frame beam (3) are connected to the steel plate (8); the annular steel plate concrete beam (2) is a centrally symmetrical annular or eccentric annular structure. According to the joint, the stressed steel bars (11) of the reinforced concrete frame beam (3) are anchored by the steel plate (8), so that the seismic performance of the connecting joint is ensured. The present invention also relates to a construction method for a joint of a concrete-filled steel tube column and an annular steel plate concrete beam.
