A high-performance multifunctional integrated composite wall panel system, which was composed of a high-performance thin-walled large cavity shell and multifunctional core, was proposed in consideration of the advantages of ultrahigh-toughness cement-based composite materials, the standard panel surface density was ≤75 kg/m2, and the minimum ultimate flexural load was 2,333 N/m2, and according to the thermal engineering theory, the heat transfer coefficient of modified polystyrene particles foamed concrete for the multifunctional core was calculated as 0.756W/(m2·K), and that of the designed three-layer (standard panel + 35 mm rock wool+ gypsum plasterboard) composite structure was 0.481W/(m2·K). By combining the characteristics of standard panel, customized exterior wall, sealing, waterproof, and other measures were proposed, and meanwhile, multiple structural combinations were constructed to meet the energy conservation design needs in different climatic regions.
