How to Build a Container House

Building a container house requires completing steps such as purchasing, ground treatment, container body assembly and modification, installation, and post-maintenance in sequence, as detailed below:

I. Purchasing Stage

1. Structural Type Selection: Welded integral containers have strong deformation resistance and are suitable for frequent lifting and moving; bolt-connected assembled containers have lower costs but require inspection of the tightness of connection nodes.
2. Steel Specifications and Coatings: It is recommended that the wall thickness of the steel for columns and bottom beams be between 1.5 mm and 3 mm, balancing self-weight and load-bearing capacity; hot-dip galvanized coatings are preferred for the container body surface for longer corrosion resistance.

II. Ground Treatment

1. Foundation Construction: For long-term use, a concrete strip foundation should be poured, with a width of 30 cm to 50 cm and a depth adjusted according to the frost line; the top surface should have a horizontal error of no more than 5 mm. For short-term use, prefabricated concrete blocks or steel pads can be used, with a spacing of no more than 2 m, and a crushed stone leveling layer should be laid underneath.
2. Anti-Settlement Measures: Remove the floating soil on the ground and compact the original soil layer to avoid uneven settlement of the container body due to local pressure.

III. Container Body Assembly and Modification

1. Space Expansion: Functional zoning can be achieved through horizontal assembly, vertical stacking, or staggered-level design. For example, connecting two containers can create a layout with an integrated living and dining room plus two bedrooms.
2. Functional Enhancement: Cut openings for doors and windows and install them, build wooden frames inside and fill with insulation (such as rock wool boards), lay water and electricity pipelines, and install facilities such as real-fire fireplaces and solar systems.

IV. Installation and Debugging

1. Lifting and Positioning: Use steel wire ropes with sufficient load-bearing capacity for synchronous lifting to ensure uniform force on all lifting points; after the container body is positioned, check the fit between the bottom beam and the foundation pad, with a levelness error controlled within 2 mm per meter.
2. Sealing Treatment: Perform waterproof sealing on the container body assembly seams, around doors and windows, and other parts; regularly replace the sealant and clean the leaves on the roof.

V. Post-Maintenance

1. Rust Prevention and Corrosion Resistance: Check welds, corners, and other parts annually, and immediately grind and repaint any rust spots found; in inland areas, recoat with anti-corrosion paint every 8-12 years, in southern humid areas every 7-10 years, and in coastal areas every 3-5 years.
2. Insulation and Ventilation: Install qualified insulation layers on walls and roofs and add vapor barriers; improve ventilation through exhaust fans or high windows to avoid internal condensation.
