Assembly Plan for Small Container Houses
The assembly of small container houses should be completed in six steps: design planning, foundation construction, main structure assembly, enclosure installation, interior decoration, and safety acceptance, ensuring both functionality and safety.
I. Design Planning and Requirement Analysis
Clarifying the purpose is crucial. For home use, ventilation and lighting should be enhanced; for temporary offices, rapid assembly and disassembly are prioritized; and for entrepreneurial shops, display functionality should be highlighted. In terms of size selection, a 20-foot container (about 6 meters long) is recommended for home use or small shops, while 10-foot containers (about 3 meters long) can be spliced for temporary offices. When combining multiple containers, an "L-shaped splice" can be used for home use to increase balcony space, while a "side-by-side splice" with a reserved corridor for rain protection is suitable for temporary offices. Functional zoning should align with the scenario: for home use, divide into bedrooms, living rooms, and kitchens, with a 3-square-meter balcony in the middle; for temporary offices, set up a reception area, office, and pantry; and for entrepreneurial shops, plan for a cash register, display shelves, and storage room.
II. Foundation Construction and Container Preparation
The site should be flat and solid, with a bearing capacity of ≥150kPa. Weak foundations should be replaced with graded sand and gravel and compacted to over 95%, using concrete foundations or heavy sleepers to distribute weight. Containers should be cleaned and rust removed, with deformed parts repaired and cut as needed for modifications, such as converting one side of a shop into a folding door to expand operating space.
III. Main Structure Assembly
During positioning and lifting, use a total station to control axis deviation ≤ ±5mm, and pad 20mm-thick steel plates at container corners for leveling. The lifting sequence should follow "corners first, then sides, outside first, then inside," with the angle between the wire rope and container ≥60°. For connection and fixation, use M20 high-strength bolts (torque 400N·m) for corner fittings and continuous welding (weld leg height ≥4mm) for side panels; for temporary office scenarios, bolts can be used for easy disassembly and movement.
IV. Enclosure Structure and Equipment Installation
For thermal insulation and soundproofing, install 100mm-thick rock wool boards, with seams sealed with sealant and gaps around doors and windows sealed with weatherstripping. For home use, install 1.2-meter-wide sliding windows on the sides and skylights on the top; for shops, the exterior walls can be painted in pastel colors and decorated with personalized stickers. The electrical system should use flame-retardant cables laid in galvanized steel pipes, with a distribution box at 1.5m height and sockets at 0.3m height; the plumbing system should use PPR pipes for water supply with hot-melt connections and UPVC pipes for drainage with adhesive connections.
V. Interior Decoration and Detail Handling
Lay waterproof floor leather (for home use) or wooden floors and tiles (for temporary offices) on the ground, and paint the walls in light colors or install gypsum boards. For functional optimization, home partitions should have storage space without blocking light, temporary offices should use low partitions to distinguish workstations, and file cabinets can be placed in corridors.
VI. Safety and Acceptance
Set up warning zones for lifting operations, wear safety belts for high-altitude work, and ensure grounding resistance ≤1Ω. Acceptance criteria include a main body verticality deviation ≤ H/1000 and ≤20mm, a levelness deviation ≤ L/1000 and ≤15mm, doors and windows meeting national airtightness standards, and normal operation of the water and electricity systems.
