Specification Requirements for Prefabricated Assembled Housing

The specification requirements for prefabricated assembled housing cover multiple aspects such as structural systems, materials, design, construction, fire safety, building material usage, and building planning approval.

Specification for Assembled Rural Houses (Taking Shandong Province as an Example)

• Structural Systems: Clearly define assembled concrete shear wall structural systems, EPS module cast-in-place concrete structural systems, light steel frame structural systems, etc., and provide detailed design and construction specifications to ensure structural safety.
• Material Requirements: Materials should be selected based on local conditions and available resources, choosing green, economical, or recyclable building materials. Priority should be given to local building materials, and the use of high-energy-consuming and excessively polluting materials is prohibited.
• Design Requirements: Respect the housing needs of farmers and reflect regional characteristics; consider age-friendly design, such as providing barrier-free ramps at entrances; the floor plan and facade design should facilitate winter sunlight and summer ventilation, preferably with a north-south orientation; the building shape should be simple and regular, with a regular floor plan and vertically aligned load-bearing components; functional spaces should include bedrooms, dining rooms, storage spaces, courtyard spaces, etc., and the division of living spaces should ideally achieve a separation of dynamic and static areas.
• Construction Requirements: Construction should preferably be carried out by professional construction teams or trained rural individual builders with housing construction capabilities; a construction organization design and construction plan should be formulated, including component installation and joint construction plans, quality management for component installation, and safety measures.

Specification Requirements for Prefabricated Panel Houses (National Level)

• Fire Safety Regulations: Prefabricated panel houses may use flammable materials and must strictly comply with fire safety regulations. According to the Fire Protection Law of the People's Republic of China, fire rescue agencies will notify relevant units or individuals to take immediate measures to eliminate fire hazards if they are found during fire safety inspections.
• Building Material Usage Regulations: Building materials that comply with national standards should be used. The use of flammable foam sandwich panels is strictly prohibited in crowded places, and non-flammable or difficult-to-burn materials such as rock wool should be used instead.
• Building Planning and Approval: It should comply with local land use planning and relevant laws and regulations. Before construction, applications for land use rights and building permits should be submitted to ensure the legality and standardization of the building.
