Nanjing International Exhibition Center, the second floor of the framework for a large area of prestressed concrete without seam structure, the plane with vertical and horizontal post-pouring tape, prestressed tendons connector. During the construction, the concrete measures were taken to solve the technical difficulties of fixing the end of the tension, passing the beam, connecting the prestressed tendons and grouting in the tunnel. The modern management mode was adopted to organize large-area prestressed construction to effectively control the concrete temperature in the slab stress
