Prefabricated House Assembly Plan

The assembly plan for prefabricated houses covers five key stages: design, production, transportation, installation, and quality control. Each stage must work in harmony to ensure the structural safety of the house, efficient construction, and compliance with standards.

Design Phase

• Design Principles: Must meet architectural functional requirements, ensure structural safety and stability, while adhering to green building concepts to reduce energy consumption. Design should consider the convenience of construction, transportation, and installation, adopting standardized and modular designs to suit industrial production.
• Design Content: Includes architectural plan, elevation, and structural design, as well as equipment selection and material choice. Structural design employs prefabricated assembled structures, achieving the construction of the house's main framework through modular combinations.

Production Phase

• Production Process: Produce prefabricated components such as wall panels, floor slabs, beams, and columns according to design drawings; assemble components into the house's main structure; inspect components for dimensions and strength; finally, package and protect component surfaces for transportation.
• Production Requirements: Component dimensions must be precise, with flat and defect-free surfaces (e.g., no cracks, honeycombs, or pockmarks); connection node designs must be reasonable to ensure connection strength meets design requirements; production processes must comply with relevant national standards, such as the "Technical Standard for Prefabricated Concrete Buildings."

Transportation Phase

• Transportation Methods: Select tools such as flatbed trucks or trailers based on component dimensions and transportation distance to ensure component stability during transit.
• Transportation Requirements: Components must be secured before transportation to avoid collision damage; plan routes to avoid congested or construction areas to minimize bumps; transportation vehicles must be regularly maintained to ensure normal braking and suspension systems.

Installation Phase

• Installation Process: Clear the construction site to ensure a flat foundation; use cranes and other equipment to lift components to designated positions; connect components according to design requirements (e.g., bolt connections, welding, or wet connections); adjust component levelness and perpendicularity to ensure house structural stability; finally, conduct inspections to check connection strength and flatness against standards.
• Installation Requirements: Handle components gently during installation to avoid damage; installation quality must comply with relevant national standards, such as the "Code for Construction and Quality Acceptance of Prefabricated Concrete Structures"; construction personnel must wear safety protective equipment to ensure safe operations.

Quality Control

• Design Phase: Review design drawings to ensure structural safety and functional rationality; train designers to improve design skills.
• Production Phase: Monitor the production process to ensure component dimensions and strength meet design requirements; conduct spot checks or full inspections on finished products, with non-conforming items requiring rework or scrapping.
• Transportation Phase: Monitor the transportation process to ensure components are undamaged; inspect transportation vehicle conditions to avoid component overturning due to vehicle failures.
• Installation Phase: Monitor the installation process to ensure connections are secure and adjustments are in place; during acceptance, check the overall stability and sealing of the house to ensure compliance with design requirements.
