Abstract
A reinforced compound concrete beam-column joint containing demolished concrete lumps and a construction method are disclosed. The steel strip stirrups configured to constrain column longitudinal reinforcements of the reinforced compound concrete column containing demolished concrete lumps and the steel connection sheets with grooves are arranged in joint at positions of the upper and lower beam longitudinal reinforcements of the reinforced compound concrete beam containing demolished concrete lumps. The steel strip stirrups abut against the column longitudinal reinforcements. The steel connection sheets are welded to the steel strip stirrups. One end of the short steel bars with threads at one end is welded into the grooves of the steel connection sheets, and the other end is connected to the beam longitudinal reinforcement via a steel sleeve. The joint prevents the beam longitudinal reinforcements from passing through the joint and thus causing reinforcements congestion.
