Prefabricated Single-Story House Design Specification
The design specification for prefabricated single-story houses should comprehensively consider multiple aspects, including design principles, structural systems, material selection, layout and functionality, energy-saving measures, construction techniques, and regional characteristics.
Design Principles: It should comply with national architectural design standards, ensuring safety, applicability, aesthetics, and economy, while meeting the living needs of rural residents, covering functions such as residence, entertainment, and social interaction. Emphasis should be placed on energy-saving design, improving thermal insulation performance, optimizing layout to enhance land utilization efficiency, and simplifying construction techniques to reduce costs.
Structural Systems: Clearly adopt prefabricated structural systems, such as prefabricated concrete shear walls, EPS module cast-in-place concrete, or light steel frame structures. Detailed design and construction specifications should be provided to ensure structural stability and safety.
Building Materials: Prioritize the use of green, economical, and recyclable local materials. The use of high-energy-consuming or polluting materials is prohibited. For walls, hollow bricks or aerated concrete blocks are recommended. For roofs, thermal insulation materials such as cement tiles should be used. Double-glazed windows and doors should be employed to enhance thermal insulation performance.
Building Layout and Functionality: The entrance should be independently set up. The living room should have an area of 20-30 square meters, with 2-3 bedrooms (each 10-15 square meters), a kitchen of 6-8 square meters, 1-2 bathrooms (each 3-5 square meters), and a storage room of 3-5 square meters. Functional spaces should be separated into active and quiet areas, with reasonable division of living spaces.
Building Energy Efficiency: Energy-saving lighting fixtures should be used to reduce lighting energy consumption. The floor plan and facade design should facilitate winter sunshine and summer ventilation. A north-south orientation is recommended to optimize natural lighting and ventilation effects.
Construction Techniques: Prefabricated components should be manufactured in factories or partially prefabricated to ensure consistent quality. Construction organization should integrate design, production, and assembly principles, coordinating requirements across various specialties. The construction plan should include component installation, joint construction, quality management, and safety measures.
Other Requirements: The architectural style should reflect regional characteristics, such as the traditional styles of central Shandong, northwest Shandong, southwest Shandong, and the Jiaodong Peninsula. Additionally, considerations should be made for aging-friendly design, with barrier-free ramps installed at entrances to enhance living convenience and safety.
