Temporary Container House Production

The production of temporary container houses requires comprehensive consideration of structural design, material selection, installation processes, and compliance requirements. The core processes include frame construction, wall installation, functional integration, and on-site commissioning. The following provides a detailed explanation from four aspects: technical considerations, material selection, installation procedures, and compliance standards.

I. Structural Design Must Meet Mechanical Performance and Scenario Adaptability
The frame of container houses should use high-strength steel (such as Q345B) to ensure wind and earthquake resistance. For example, the packing-box units produced by Suzhou Zhongnan Steel Structure Co., Ltd. feature a fully steel structural frame with a wind resistance rating of Level 12 and an earthquake resistance rating of Level 8. The frame deformation rate is only 0.18%, significantly lower than the industry's acceptable threshold of 0.3%. For multi-story stacking scenarios (such as three-story dormitories), C-shaped steel purlins should be added between the bottom beams to distribute the load and prevent insufficient floor stiffness. Additionally, welded integral boxes (factory-welded as a whole) have stronger deformation resistance than bolted assembled boxes, making them more suitable for frequent lifting and moving scenarios.

II. Material Selection Should Balance Durability and Environmental Protection

1. Steel Corrosion Protection: The box surface should undergo shot blasting for rust removal, followed by the application of a zinc-rich primer and a polyurethane topcoat. This protective system enables the steel to maintain effective service life for over 15 years in environments with wind, sand, and temperature variations.
2. Wall Materials: Priority should be given to fire-resistant polyurethane sandwich panels (B1 grade or higher). Flammable materials (such as C-grade fire-resistant materials) should be avoided to delay the spread of fire.
3. Floor Materials: Moisture-resistant and corrosion-resistant bamboo plywood or PVC flooring can be used to adapt to humid environments like construction sites.

III. Installation Procedures Should Be Standardized to Improve Efficiency

1. Foundation Preparation: Ensure the ground is level and use a concrete foundation or steel ground beams to prevent box settlement.
2. Frame Lifting: Use lifting equipment to position the prefabricated frame and check for verticality and levelness.
3. Wall and Roof Installation: Install color-steel sandwich panel walls sequentially, paying attention to the waterproofing of sealing strips; the roof should have a drainage slope (usually ≥5%).
4. Functional Integration: Pre-embed water and electricity pipelines and install doors, windows, lighting, and ventilation systems. Products from leading manufacturers (such as Suzhou Zhongnan's packing-box units) can have interiors and facilities pre-installed, allowing for immediate use after on-site lifting, with a single installation taking only 2 hours.

IV. Compliance Must Meet National Standards and Industry Regulations

1. Structural Safety: The product must pass wind and earthquake resistance certifications (such as the national standard GB/T 19001 requiring wind resistance of Level 8 or higher). Non-standard off-brand products (with wind resistance ratings of only Level 6-7) should be avoided as they are prone to deformation and cracking.
2. Fire Performance: The product must meet the B1 fire resistance standard, and exported products must have international certifications such as CE and ISO.
3. Environmental Requirements: The material's reusability rate should reach over 80%, and the use of disposable materials should be avoided to reduce construction waste.
4. After-Sales Service: The manufacturer should establish a nationwide service network with a response time of no more than 24 hours to ensure timely problem resolution.
