How to Build a Container House
The construction of a container house involves several steps, including selection, ground preparation, lifting and positioning, assembly, insulation and lighting treatment, and post-maintenance. Details are as follows:
Selection Phase: Pay attention to the structural type of the container house, commonly available as welded integral units and bolt-connected assembled units. Welded units have strong deformation resistance and are suitable for frequent lifting and movement; assembled units require inspection of the steel wall thickness of columns and bottom beams (common specifications range from 1.5mm to 3mm) and the coating process on the container surface (hot-dip galvanizing offers longer corrosion resistance).
Ground Preparation: Provide a uniform load-bearing foundation for the container house. For long-term fixed use, pour a concrete strip foundation (width ranging from 30cm to 50cm, depth determined by the thickness of the permafrost layer, with a top surface level difference not exceeding 5mm); for short-term use, prefabricated concrete blocks or steel plates can be used (spacing not exceeding 2m, with a crushed stone leveling layer laid underneath).
Lifting and Positioning: Precisely control the contact state between the container body and the foundation, using steel wire ropes with sufficient load-bearing capacity to ensure synchronous force application at all lifting points. After the container body is positioned, check the fit between the bottom beam and the foundation pad; use thin steel plates to pad any local gaps, with a levelness error controlled within 2mm per meter.
Assembly: Assemble 2-3 containers according to needs, either side by side or stacked in an offset manner, to expand functional areas such as living rooms, bedrooms, and bathrooms. Offset design can improve ventilation and lighting; for small units, it is recommended to use multifunctional furniture such as folding beds and tables to enhance space flexibility.
Insulation and Lighting Treatment: Install internal insulation layers on walls/roofs and select triple-glazed windows to enhance thermal insulation performance; install large floor-to-ceiling windows, roof skylights, and glass partitions to enhance lighting; install roof eaves or balcony sunshades to prevent excessive summer sun exposure.
Post-Maintenance: Inspect welds, corners, bottoms, eaves, and other parts annually, and immediately grind and repaint any rust spots found; in inland dry areas, heavy corrosion protection and repainting are required every 8-12 years; in southern humid areas, every 7-10 years; and in coastal areas, every 3-5 years; replace the sealant around doors and windows, container assembly seams, and roof gutters every 5-7 years.
