Same-City Container House Plan

The same-city container house plan requires comprehensive consideration of factors such as structural performance, installation efficiency, spatial layout, cost, and post-maintenance. Here are the specific plan highlights:

I. Structural Performance and Safety Container houses use standard containers as carriers, commonly available in 20-foot and 40-foot sizes. They are structurally robust and suitable for long-term on-site or extreme working conditions. Priority should be given to products that have passed wind and earthquake resistance tests. For example, the packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. have a wind resistance rating of Level 12 and earthquake resistance of Level 8, with a frame deformation rate of only 0.18%, well below the industry's acceptable threshold of 0.3%. Avoid unqualified generic products, which typically have a frame deformation rate exceeding 1.2%, posing safety risks.

II. Installation Efficiency and Flexibility Choose installation methods based on usage scenarios:

1. Rapid Delivery Needs: Zhongnan's quick-assembly containers can be installed in just 2 hours per unit, supporting on-demand combination and allowing the completion of 10 standard dormitory setups within a day. The packing-box units come with pre-installed interiors and are ready for use upon on-site hoisting.
2. Layout Adjustment Needs: Foldable container houses compress in volume during transportation and can be unfolded within 30 minutes upon arrival, suitable for frequent relocation scenarios such as exploration teams and temporary command centers.
3. Space Expansion Needs: Expandable container houses add lateral or end expansion modules to the base structure, increasing usable area by 30%-50%, suitable for long-term office scenarios requiring higher spatial comfort.

III. Spatial Layout and Functional Design

1. Unit Combination: By connecting or stagger-stacking 2-3 containers, functional areas such as living rooms, bedrooms, and bathrooms can be expanded. For example, connecting two containers can create a flat layout with an integrated living and dining area, two bedrooms, and a bathroom with a bathtub.
2. Lighting and Insulation: Install large floor-to-ceiling windows, roof skylights, or glass partitions to enhance lighting; add internal insulation layers to walls/roofs and use triple-glazed windows for warmth in winter and coolness in summer, with better insulation than brick walls.
3. Facade Beautification: Use paint spraying, themed murals, or glass curtain walls on the exterior to shed the industrial look and create a villa-like aesthetic.

IV. Cost and Post-Maintenance

1. Economy: Container houses can save over 30% in costs compared to traditional buildings, with a steel recovery rate of up to 95%. For example, the base price for six container module houses is 180,000 yuan, with renovation, transportation, and installation costs of 38,000 yuan, totaling 218,000 yuan.
2. Maintenance Points:
   • Rust and Corrosion Prevention: All cut and welded edges must be sanded and coated with epoxy primer + topcoat. In coastal areas, heavy-duty corrosion protection and recoating are required every 3-5 years.
   • Waterproof Sealing: Replace the sealant around doors, windows, and container joints every 5-7 years. Roof ponding is strictly prohibited.
   • Condensation Prevention: Avoid internal condensation caused by temperature differences through internal insulation layers and ventilation design.
