How to Assemble Container Houses

The assembly of container houses primarily relies on modular design, enabling rapid on-site assembly through standardized components without the need for complex construction or professional welding. The core steps include foundation preparation, frame assembly, wall and roof installation, and internal connections.

1. Foundation Preparation and Bottom Frame Installation

Before assembly, ensure the ground is level, using either a concrete foundation or a workbench. For a standard container house, connect the bottom corners of the container to the bottom beams with hexagon socket bolts, but do not tighten them yet. Adjust the diagonal error of the bottom frame to ≤3mm before fully securing it. Then, install π-shaped secondary beams, fixing them to the top of the bottom beams with self-tapping screws and round-head drill tail screws to form the floor support structure. Cut and lay the floor base plates (such as magnesium oxide boards) according to the positioning lines, aligning the joints with the centerline of the π-shaped beams. Secure them with cross-flat-head燕尾丝 (Note: '燕尾丝' may not have a direct English equivalent; consider using 'dovetail screws' if applicable or describe as 'special screws for alignment'), spaced 300-350mm apart. Finally, sand, glue, and lay the floor covering.

2. Steel Frame Assembly

For multi-story or expandable container houses, assemble the steel frame first. For example, fix square tube columns to steel beams with screws, checking for verticality and straightness. Then, install the main beams and section beams one by one, using plumb lines and steel tapes to correct their positions. For foldable container houses, unfold the main frame with a crane, place support rods in the middle of the container to maintain stability, then push open the walls and tighten the screws. This entire process takes only 3 minutes and can be completed by two people.

3. Wall and Roof Installation

Walls are often made of rock wool, glass wool, or polyurethane sandwich panels, connected to the columns with “U”-shaped thin steel edges to form an integrated enclosure structure. The roof frame is usually made of square steel, with color steel plates laid and covered with galvanized corrugated steel plates for waterproofing. Some designs incorporate solar panels or green layers on the roof to enhance functionality and environmental friendliness.

4. Module Assembly and Internal Connections

Single containers can be stacked in multiple layers using angle steel gusset plates and bolts to form independent office units or residences. To expand the space, 2-3 containers can be connected or stacked in an offset manner to create functional areas such as living rooms, bedrooms, and bathrooms. Internal water and electricity pipelines should be pre-embedded in the factory, requiring only connection of interfaces on-site. Additionally, install fireproof and soundproof materials to ensure safety and comfort during use.
