These two traditional reinforcement systems have poor stability and low construction efficiency, which affects the construction progress. After the concrete pouring of the structural column is completed, there are many common quality problems in demolding. The joints between the tooth joints and the brick walls are prone to mold expansion, which not only destroys the integrity of the masonry structure, but also requires manpower, chiseling and repairing, and wall screw hole repairs.
