How to Assemble Container Houses

The assembly of container houses primarily adopts a modular design, with standardized components prefabricated in factories and assembled on-site like building blocks, without the need for complex construction or welding. The specific assembly process and key points are as follows:

I. Foundation Preparation and Bottom Frame Installation
Operations should be carried out on a flat ground or workbench. First, connect the bottom corners of the container to the bottom beams using hexagon socket bolts, but do not tighten them yet. After adjusting the diagonal difference of the bottom frame to be ≤3mm, fully tighten the bolts. Then, install π-shaped secondary beams according to the positioning holes on the long beams, secure them with self-tapping screws, and reinforce the tops of the secondary beams and bottom beams with round-head drill-tail screws. Lay the floor base plates along the 6-meter direction, cut the corners of the base plates with pre-drilled holes at both ends according to the chalk lines, and mark them at the centerline of the π-shaped beams to prepare for subsequent floor laying and nailing.

II. Floor Laying and Fixing
Start laying the floor from one end, ensuring that the joints align with the centerline of the π-shaped beams. After laying, snap chalk lines according to the centerline markings (two chalk lines are required at the joints, each deviating 20mm from the centerline). Fix the floor along the chalk lines with cross-flat-head swallow-tail screws, with a nailing interval of 300-350mm. Finally, sand the floor joints as a whole, apply PVC special floor adhesive, wait for 10-15 minutes, lay the floor covering, and expel the air. If conditions permit, welding treatment can be performed at the joints.

III. Steel Structure Assembly and Wall Installation
Assemble square tube columns and steel beams with screws, ensuring that the steel beams are vertical and straight, and the component dimensions meet the requirements. Install the steel beams one by one, support them with square tube columns, adjust the verticality with a plumb line, and measure the positions accurately with a steel tape measure. Fix the secondary beams to the main beams with screws. After all installations are complete, check the positions of the steel beams again and make adjustments if there are any deviations. After confirmation, weld the horizontal supports and the internal threading of the steel beams, and then weld the square tube columns and chassis iron. The walls are usually 50mm thick rock wool or slag wool color-coated steel plates, which are connected to the main load-bearing components such as the base by spot welding.

IV. Module Connection and Overall Fixing
If space expansion is required, 2-3 containers can be connected or stacked in an offset manner. For example, connecting two containers can create a flat layout with an integrated living and dining room, two bedrooms, and a bathroom with a bathtub. When stacking up and down, fix them with bolts through the four angle steel gusset plates at the corners. For foldable container mobile homes, first lift the main frame, place the support rods after unfolding, then push open the walls and fix them with tightening screws.
