In the fabricated concrete structure, beam-column connection is closed, and the node connection form has an important influence on the strength and deformation of the structure. Therefore, the beam-column connecting structure has important significance for construction and engineering quality.

In the prefabricated concrete structure in the past, through reinforcing bar and cast in situ concrete with beam column connection, but in the connection process, the reinforcing bar on the post is exposed outside, often because factors such as environment, manual work for the reinforcing bar takes place certain deformation, thereby causes very big puzzlement to connection work, has influenced engineering quality and efficiency of construction. Meanwhile, the pouring of cement can not fully fill cement in the beam due to carelessness of workers, and the engineering quality is seriously influenced.
