With the development of the building industry, the mode of prefabricating reinforcing steel bars into finished components and then integrally connecting the components is gradually adopted in building construction, namely, a plurality of reinforcing steel bars are manufactured into an integral reinforcing steel bar mesh and a reinforcing steel bar cage before reinforcing steel bar connection construction, and then the reinforcing steel bar components are integrally connected. This kind of finished product steel reinforcement cage reinforcing bar can only follow axial displacement when connecting, can not rotate, has restricted the reinforcing bar and has twisted telescopic realization, and when carrying out the steel reinforcement cage installation, the scene needs sleeve and reinforcing bar axial to accurately align, just can guarantee the smooth installation of steel reinforcement cage, but steel reinforcement cage sleeve is more, and the steel reinforcement cage is in prefabricated shaping and transportation hoist and mount in-process the reinforcing bar deformation and the dislocation of difficult emergence, many reinforcing bars align very difficultly simultaneously, this will increase the degree of difficulty of steel reinforcement cage installation and reduce the efficiency of construction.
Based on the above situation, it is necessary to design a new reinforcing bar connecting mechanism.
