Scope

Main technical content: The HF prefabricated modules use industrial by-products such as gypsum, fly ash, and furnace slag as the main raw materials, and cement, slag, and lime as modifying materials. They are cast and molded in a dedicated mold box. The product structure is unique, with double-sided concave and convex tenons on all four sides. After assembly into a wall, the tenon structure significantly enhances the wall's shear resistance and seismic resistance. The wall has extremely high flatness, eliminating the need for leveling and plastering, making it the only product on the market that truly achieves this. The wall also offers excellent sound insulation, with a 200-mm-thick wall achieving 50dB. The wall has excellent fire resistance, with a fire resistance limit of up to 3.0 hours. The main technical content of this standard includes: ① The quality and performance requirements of HF-type prefabricated modules, including product definition, material composition, various mechanical performance indicators, and wall performance, along with inspection standards; ② Technical design, including principles for mechanical design and calculation of walls, and energy-saving design principles; ③ Detailed provisions on construction methods, including construction procedures and plans; ④ Acceptance regulations, which specify factory acceptance conditions, on-site acceptance conditions, and acceptance batches, etc.
