COVID Container House

COVID container houses are temporary accommodations transformed from containers, often used as isolation points and makeshift hospitals during epidemic prevention and control. They feature rapid construction and flexible mobility but also pose fire safety risks, requiring standardized use and management.

Definition and Structure

COVID container houses are essentially modified containers, using standard containers as basic units to construct modular buildings through steel frames and lightweight wall panel structural systems. Their structure consists of top frame components, corner post systems, and bottom frame components. Each module is prefabricated in factories and assembled on-site, allowing for free horizontal or vertical combination and even three-story stacking, providing flexible and variable space.

Application Scenarios

During COVID epidemic prevention and control, these houses are widely used as isolation facilities in high- and medium-risk areas, such as isolation sites, makeshift hospitals, and temporary medical facilities. For example, the Huangzhuang Apartment isolation site in Shijiazhuang delivered 1,008 container houses in 98 hours; Taizhou produced 400 container board houses within 48 hours to support epidemic prevention efforts in Shaoxing; Jiangmen produced over 10,000 modular box-type houses to support the construction of makeshift hospitals in Hong Kong. Additionally, some houses have been repurposed into affordable rental housing after the epidemic, achieving a "dual-use" approach for both normal and emergency situations.

Advantages and Characteristics

• Rapid Response: Modular design enables quick construction within a short time, meeting urgent isolation needs during the epidemic.
• Flexible Mobility: They can be transported as a whole or in parts, adapting to rapid deployment in different scenarios.
• Diverse Functions: Through combination, they can realize multi-functional spaces such as offices, dormitories, meeting rooms, and bathrooms.
• Recyclability: The steel frame structure is highly durable, with a service life exceeding 20 years, allowing for repeated use and low average costs.

Safety Hazards and Regulatory Requirements

• Fire Risks: Some houses use flammable materials such as polystyrene and polyurethane foam, posing risks of ignition from electrical welding sparks or cigarette butts, with fast combustion, high toxicity, and difficulty in extinguishing.
• Safety Standards: They must use Class A fire-resistant materials such as rock wool boards and fireproof cotton, maintain safe distances, standardize the laying of wires and cables, equip with fire extinguishing equipment, and avoid proximity to heat sources and fire sources.
