Container House Construction Process

The construction process of container houses is mainly divided into two stages: factory manufacturing and on-site installation, with the following specific steps:

I. Factory Manufacturing Stage

1. Design Phase
   Complete structural design and detailed drawings based on user requirements, specifying house dimensions, functional layout, and material specifications. For example, for packing-box container houses, the load-bearing parameters of the hot-dip galvanized cold-formed steel frame need to be determined, and for light steel keel houses, the type of insulation material for wall filling needs to be planned.

2. Steel Structure Processing
   Carry out steel cutting, welding, and surface treatment to form a standardized frame. This step must strictly adhere to welding process standards to ensure the frame strength meets design requirements, such as a 20-foot container being able to bear a load of up to 25 tons.

3. Wall and Roof Panel Composite Processing
   Fill with insulation material and apply facing to complete the prefabrication of wall and roof panels. For example, fire-resistant polyurethane sandwich panels must meet Class A fire resistance standards, and rock wool panels used in residential houses must comply with the regulation that the building area of each unit should not exceed 300 square meters.

4. System Pre-installation
   Integrate systems such as doors, windows, electrical, and plumbing, and complete pipeline embedding and interface connection. For example, smart home devices can be pre-embedded and integrated, and bathroom modules can be prefabricated in the factory to reduce on-site wet work.

5. Trial Assembly and Quality Inspection
   Conduct trial assembly of modules before leaving the factory to verify component compatibility and structural stability. Through quality control processes such as load testing and airtightness detection, ensure the house meets safety requirements for wind and earthquake resistance.

II. On-site Installation Stage

1. Foundation Construction
   Level the site and lay a concrete foundation, reserving anchor bolts or embedded parts. For example, light steel keel houses require the pouring of strip foundations, and container modules need to be fixed to the foundation through corner fittings.

2. Module Hoisting and Assembly
   Use lifting equipment to hoist prefabricated modules to designated positions and complete horizontal assembly and vertical stacking through bolt connections or welding. For example, in a wind power project camp in Xinjiang, 180 containers were arranged in an 'I' shape to complete the construction of a living area for 500 people within 7 days.

3. System Commissioning and Acceptance
   Connect water and electricity pipelines and test the electrical system, plumbing functions, and fire protection facilities. For example, solar panels and rainwater collection systems need to be adjusted to achieve 30% self-sufficiency in electricity, and double-layer rock wool insulated glass needs to pass sound insulation tests.

Process Advantages: Standardized factory production can shorten the construction period by more than 60%, reduce on-site work by 80%, and modules can be repeatedly disassembled and assembled with a turnover rate of over 90%, making them suitable for scenarios such as temporary construction sites and emergency housing.
