Scope

Scope: 1. Design, construction, and acceptance of non-load-bearing prefabricated composite insulation exterior wall panels for civil and industrial buildings in areas with seismic fortification intensity of 8 degrees or lower. 2. The following situations are not allowed to directly use prefabricated VRP panels: 1) Exterior walls below ±0.000 of the building; 2) Environments subject to long-term immersion in water or chemical corrosion; 3) Surfaces frequently exposed to high temperatures above 80°C; 4) Environments with long-term vibration sources. Main technical content: 1. The prefabricated lightweight concrete composite insulation exterior wall panels are made by incorporating FRPC reinforcing mesh cages into lightweight concrete and using a special hollow layer process to create lightweight concrete slabs with reinforcing ribs and hollow structures. Double-component foamed polyurethane is injected into the hollow structures to form lightweight self-insulated composite exterior wall panels, referred to as composite insulation exterior wall panels, also known as VPR panels. They include Type I panels and Type II panels. 2. Lightweight concrete includes autoclaved sand-gas concrete (used for Type I panels) and ceramic sand concrete (used for Type II panels). The autoclaved sand-gas concrete has a dry apparent density of no more than 750 kg/m3 and a compressive strength of no less than A5.0; the ceramic sand concrete is made from ceramic sand and vitrified micro-pearls as aggregates, combined with cementitious materials, admixtures, and water, and is steamed to form a dry apparent density of no more than 1000 kg/m3 and a compressive strength of no less than LC7.5. 3. The fiber-reinforced mesh cage is made of fiber-reinforced composite reinforcement bars, manufactured and assembled in the factory, and used for the production of VPR panels specified in this collection. It is referred to as a fiber-reinforced mesh cage, or simply FRPC mesh c
