Abstract:In recent years, China's construction industry vigorously promotes construction industrialization. In order to solve the problems of connection integrity of reinforced concrete precast structure, a new type of formwork-free precast integration industrial structural system (PI structure system for short) was proposed. The technical idea of PI structural system, the experimental results of mechanical performance of members, and its application in multi and high-rise buildings were described. The research and application results show that the mechanical properties of the structural system are completely consistent with that of the cast-in-place system, because the installation is simple and fast and the construction period is saved, and it has a broad application prospect.
Keywords:precast structure; PI structure system; formwork-free; cage formwork member; shaped grid stirrup
