AI Technical Summary
Traditional reinforced concrete structures lack sufficient load-bearing capacity and durability in large spans and special environments. PVC-FRP pipes have unclear force transmission paths and complex construction in the connection of vertical load-bearing components, which restricts the promotion of engineering projects.
Precast PVC-FRP pipes are used to connect reinforced concrete columns. The upper and lower columns are connected by straight threaded sleeves and joint grouting material. Combined with FRP strips and PVC connecting pipes, a clear force transmission path is formed. Grouting material is injected into the joint area and FRP strips are wrapped around it to improve the load-bearing capacity and deformation coordination of the joint area.
It achieves convenient construction and clear force transmission, improves the bearing capacity and concrete strength of the joint area, simplifies the construction steps, is suitable for fully factory-made and prefabricated production, and enhances the reliability and durability of the structure.
