22 Container House

The "22 container house" generally refers to a modular building with an internal volume of 22 cubic meters, utilizing a light steel structure and composite panels, featuring rapid assembly, mobility, and low cost.

Technical Principles and Structural Features

The 22 container house employs light steel keels as its main framework, covered externally with fire-resistant rock wool sandwich panels or EPS foam sandwich panels, forming a high-strength, lightweight structural system. Its core design is modular prefabrication, with all components (such as walls, doors, windows, and electrical circuits) produced in a factory to standardized specifications and rapidly assembled on-site using bolts or welding, eliminating the need for complex construction techniques. This structure can withstand wind and snow loads of 0.5-0.8kN/m², achieve a fire rating of B1 (non-combustible), meet IP55 waterproof standards, and typically has a service life of 15-20 years.

Application Scenarios and Advantages

The moderate space of 22 cubic meters makes it suitable for scenarios such as temporary office areas, construction site dormitories, scenic area homestays, mobile sales kiosks, and rural self-built houses. Compared to traditional brick-and-mortar buildings, its advantages include:

1. Short construction period: Factory-prefabricated components reduce on-site construction time, allowing a standard house to be assembled in 3-5 days;
2. Low cost: No foundation construction is required, and materials can be reused, reducing overall costs by 30%-50%;
3. Flexible functionality: The interior can be divided into functional areas such as living rooms, bedrooms, and bathrooms to meet basic living or office needs;
4. Mobility: It can be relocated as a whole using lifting equipment, adapting to temporary or mobile demands.

Purchase and Usage Considerations

1. Differentiate product types: Shipping containers are solely for cargo transport and do not have living functions; 22 container houses must comply with building standards, paying attention to wall thickness (≥50mm), steel thickness (≥2.0mm), and fire rating;
2. Transportation and lifting: Use dedicated lifting equipment to ensure even force distribution and prevent box deformation;
3. Compliance: Choose manufacturers with production qualifications and confirm that products have passed fire safety certification and structural safety inspections to avoid risks during later use.

Such houses, through industrial production and modular design, balance efficiency, cost, and functionality, becoming a preferred solution in the field of temporary buildings.
