Requirements for Prefabricated Component Assembly Houses
Prefabricated component assembly houses must meet the following requirements:
Construction Principles: Adhere to the principles of modern functionality, structural safety, cost-effectiveness, environmental friendliness, and harmonious aesthetics. Integrate local climate, topography, traditional cultural customs, and architectural characteristics to meet the functional needs of modern rural residents.
Structural Systems: Clearly define structural systems such as prefabricated concrete shear wall systems, EPS module cast-in-place concrete systems, and lightweight steel frame systems, providing detailed design and construction specifications. Rural assembled prefabricated houses often adopt frame systems, such as light steel frame systems, which offer high steel strength and can withstand significant vertical and horizontal loads, ensuring house stability.
Material Requirements: Utilize locally sourced and environmentally friendly materials that are either economically viable or recyclable, prioritizing local building materials and prohibiting the use of high-energy-consuming and excessively polluting materials. Rural assembled prefabricated houses commonly use expanded polystyrene (EPS) foam boards as insulation, with a thermal conductivity of approximately 0.038 W/(m·K); wall materials like fiber cement boards, with a fire resistance rating exceeding 2 hours; doors and windows often feature thermal break aluminum alloy frames, with air tightness ratings above level 6 and sound insulation of about 30 decibels; exterior decorations frequently employ stone-like paint, with water resistance exceeding 1000 hours.
Design Requirements: Respect the housing needs of rural residents, reflect regional characteristics, and consider age-friendly design, with entrances preferably equipped with barrier-free ramps. The floor plan and facade design should facilitate winter sunlight and summer ventilation, ideally oriented north-south. The building form should be simple and regular, with functional spaces including bedrooms, dining areas, storage spaces, and courtyard areas, and living spaces should be separated into dynamic and static zones. The foundation typically uses strip foundations with a burial depth of 0.5 to 1.5 meters; the roofing system often adopts pitched roofs with a slope of 20° to 30°, equipped with waterproof and insulation layers; indoor water and electricity lines are concealed; and seismic design follows the 'Code for Seismic Design of Buildings', enhancing overall integrity and seismic capacity through measures such as structural columns and ring beams.
Construction Requirements: Construction should be carried out by professional teams or trained rural individual builders, with a construction organization plan and construction scheme developed. The construction organization plan should be strategically planned based on the principles of integrated design, production, and assembly, with the construction scheme including component installation and joint construction plans, quality management, and safety measures. Prefabricated components are produced in factories using high-precision mold forming processes, with wall panel dimensional tolerances controlled within ±5mm to ensure precise on-site assembly and overall house quality.
