Container House Production and Installation

The production and installation of container houses involve stages such as design, production, transportation, and on-site installation, with the core being modular design and standardized processes to ensure structural stability and efficient construction.

1. Design Phase

Determine the type of house based on usage requirements (e.g., packing boxes, light steel keel houses, functional sentry boxes, etc.), and complete structural design and detailed drawings. Focus on considering spatial combination methods, such as expanding usable area through box assembly to suit residential, office, or commercial scenarios. At the same time, clarify material specifications, such as hot-dip galvanized cold-formed steel frames, rock wool or polyurethane sandwich panel walls, etc., to ensure compliance with insulation, fire prevention, and sound insulation performance standards.

2. Production Phase

1. Steel Structure Processing: Cut steel and weld it into frames, and perform surface anti-rust treatment (e.g., hot-dip galvanizing). The frames must meet wind and earthquake resistance requirements, such as the Suzhou Zhongnan packing box, which can withstand wind speeds of up to 12 and earthquakes of magnitude 8, with a deformation rate of only 0.18%.
2. Wall and Roof Panel Prefabrication: Fill with insulation materials and cover them, commonly using rock wool, glass wool, or polyurethane sandwich panels, which provide both thermal insulation and fire prevention.
3. System Pre-installation: Complete the embedding of water and electricity pipelines, doors and windows, electrical systems, etc., in the factory to reduce on-site wet work. For example, modular houses integrate interior soft furnishings into modules, which only require connection to water and electricity upon arrival at the site for use.

3. Transportation and On-site Installation

1. Transportation: Transport prefabricated modules to the site, planning lifting points to avoid structural deformation.
2. Foundation Construction: Level the ground and pour a concrete foundation, embedding drainage pipes to ensure a stable foundation. For example, in outdoor long-term use scenarios, steel frames are used to reinforce corners, and concrete piers are made at the bottom.
3. Module Assembly: Use cranes to lift modules to predetermined positions, connect frames with bolts or welding, and assemble wall and roof panels. For example, a foldable container mobile house can be installed in just 3 minutes with two operators.
4. Detail Handling: Install附属 structures (such as stairs and railings), carry out waterproofing and moisture-proofing work, and check the sealing of water and electricity systems.

4. Quality and Efficiency Control

1. Material Selection: Prioritize the use of fire-resistant and corrosion-resistant materials, such as steel-wood composite floors and metal panel walls.
2. Installation Specifications: Follow standardized processes, such as ensuring that the diagonal difference is ≤3mm during bottom frame installation and that the floor nail spacing is 300-350mm.
3. Acceptance Standards: Check the frame deformation rate and wind and earthquake resistance levels to ensure compliance with national standards (e.g., the industry's qualified threshold is 0.3%).
