The key feature of the prefabricated assembled integral concrete shear wall structural system lies in its structural connection technology, which employs two main methods: vertical and horizontal connections. Vertically, the system uses a reserved hole insertion type grout anchor connection, while horizontally, it utilizes steel bar pins along with cast-in-place joints at the composite floor slab and beam nodes.
Specifically, during the design phase, the residential building components are broken down into standardized parts, and molds are standardized accordingly. These special molds are then used in factory settings to prefabricate concrete exterior wall panels and balconies featuring decorative surfaces and insulation layers, as well as interior wall panels designed to accommodate piping systems, composite beam panels, columns, stairs, and other structural elements. Once steam-cured, the components are transported to the construction site where they are assembled using heavy lifting equipment. After placement, the joints between components are cast-in-place, connecting everything into a unified main building structure.
This system emphasizes standardized component design and shifts a significant portion of wet construction work to factory production. By applying modern management techniques for standardized manufacturing, it integrates insulation and finishing processes into the prefabrication stage. The result is high-quality components, rapid on-site assembly, and substantial reductions in raw material usage, water and electricity consumption, and labor intensity. This approach aligns with the goals of residential building industrialization, delivering savings and environmental benefits in line with the “four savings” principle.
