Haixi Container House Construction

The construction of container houses in Haixi requires comprehensive consideration of design, material selection, construction, and compliance. Here are the key points:

I. Design Planning and Spatial Layout The design of container houses should integrate functional requirements with site conditions. Two or three containers can be joined or stacked in a staggered manner to create functional areas such as living rooms, bedrooms, and bathrooms. For example, connecting two containers can form a flat layout of approximately 100 square meters, including a living-dining area, two bedrooms, and a bathroom with a bathtub. Staggered designs improve ventilation and lighting, with the ground floor allowing for a leisure courtyard or walkway. For small units, multifunctional furniture like foldable beds and integrated cabinets is recommended to enhance space utilization.

II. Material Selection and Structural Performance

1. Main Materials: Priority should be given to sandwich panels (such as polyurethane foam integrated panels), which offer insulation, sealing, and fire resistance.
2. Structural Reinforcement: The steel frame of the container requires welding or bolt connections to enhance stability. Cut and welded areas should be sanded and painted with epoxy primer and topcoat for rust prevention.
3. Door and Window Configuration: Triple-glazed windows improve insulation and soundproofing, while roof skylights or glass partitions optimize lighting.

III. Construction Process and Installation Points

1. Foundation Treatment: Containers should be elevated on pile foundations to prevent moisture and pests and facilitate site leveling.
2. Joining and Fixing: A welding-free quick-assembly process should be adopted to minimize structural damage. High-strength bolts should be used between containers, and joints should be filled with sealant to prevent water leakage.
3. Pipeline Connection: Plan water and electricity lines in advance, reserve interface positions, and ensure synchronous connection of power and water supply networks.
4. Acceptance Criteria: After construction, inspect easily rusted areas such as welds, corners, and the bottom to ensure no leakage and structural stability.

IV. Compliance and Approval Process

1. Land Nature: Rural homesteads require construction approval with structural drawings; arable land and basic farmland are strictly prohibited from construction; forest land requires forestry approval.
2. Temporary Buildings: Leased land is mostly used for temporary structures, and the contract should clarify the nature of use to avoid illegal construction risks.
3. Cross-border Compliance: Exported products must meet the certification standards of the target country (such as CE certification) and provide domestic and foreign qualification documents.

V. Post-maintenance and Durability Enhancement

1. Rust Prevention: In inland areas, repaint with anti-corrosion paint every 8-12 years; in humid southern areas, every 7-10 years; and in coastal areas, every 3-5 years.
2. Seal Replacement: Replace sealant around doors and windows and container joints every 5-7 years.
3. Regular Inspection: Clean roof leaves annually, inspect welds, corners, and other areas, and immediately sand and repaint any rust spots found.
