Technical Requirements for Container Houses

The technical requirements for container houses cover multiple aspects such as structure, materials, installation, electrical systems, and adaptability, and must meet core standards for safety, stability, environmental protection, and efficient deployment.

1. Structural Stability Requirements

Container houses must comply with the GB50011-2010 Code for Seismic Design of Buildings, with wind resistance capabilities of Grade 8 or above (Grade 12 required in coastal or high-wind areas). The frame structure should be constructed using all-steel welding or high-strength bolt connections, with weld strength meeting the GB/T 19001-2016 standard. For example, products from Suzhou Zhongnan Steel Structure Co., Ltd. exhibit only 2mm of frame deformation under 12-grade strong winds, well below the national standard limit of 10mm. Structural joints should be reinforced, such as adding steel beams above doorways and covering internal corners with color-steel plates, to ensure long-term use without deformation.

2. Material and Environmental Requirements

• Wall Panels: Commonly use 75mm-thick rock wool color-steel plates, with a color-steel plate thickness of ≥0.5mm, providing fire resistance, thermal insulation, and sound insulation.
• Ceiling and Floor: The ceiling uses 100mm×100mm×2mm galvanized square steel tubes, while the floor main joists are 50mm×100mm galvanized pipes, with secondary joists of 40mm×80mm galvanized pipes, ensuring load-bearing capacity and corrosion resistance.
• Environmental Protection: Materials must be recyclable, with a recycling rate exceeding 80%, meeting green building standards. For example, products from Hebei Qiheng Integrated Housing Co., Ltd. are prefabricated in factories and use dry construction methods, generating no construction waste.

3. Installation and Deployment Requirements

• Modular Design: Houses should support rapid hoisting and assembly, with single-unit assembly time controlled within a few hours (top manufacturers' products require only 3 hours).
• Folding Function: Folded volume should conform to standard shipping container dimensions (e.g., 1/5 of the expanded state), facilitating cross-regional transportation.
• Waterproofing and Sealing: The roof should be designed with hidden rain gutters, and the container bodies should be locked together using specialized corner fittings to ensure uniform force transmission during multi-layer stacking.

4. Electrical and Safety Requirements

• Power Distribution System: Must adopt a three-phase five-wire system (TN-S protection system), with electrical conduits and wire trays using national standard products.
• Fire Resistance: Fire rating must reach Grade B1 or above, with core materials passing national standard flame-retardant tests (e.g., rock wool, polyurethane).
• Safety Protection: Windows should be fitted with anti-theft grilles, stair treads should have a width of ≥300mm and a height of 150-160mm, and be equipped with stainless steel handrails.

5. Multi-Scenario Adaptability Requirements

Houses should support horizontal assembly and vertical stacking, allowing free combination into different functional spaces such as office areas, dormitory areas, and medical stations. For example, double-wing expansion containers can increase internal area by 2.3 times when expanded, suitable for scenic spot homestays and temporary exhibition halls; corrugated containers use wear-resistant corrugated steel plates, making them suitable for high-impact environments like industrial and mining areas.
