Wuchuan Temporary Container House

The Wuchuan temporary container house is a green community service building constructed using modular integration technology, combining functionality and energy efficiency, but requiring strict prevention of fire hazards.

I. Functional and Technical Features

The container houses in Wuchuan use standard container modules as basic units, achieving 'factory prefabrication + on-site assembly' through modular integration technology. Each module has completed the integration of structure, insulation, piping, and partial decoration before leaving the factory, enabling rapid assembly into small public buildings such as community service stations. Their technical advantages are reflected in:

1. Optimized Envelope Structure Performance: The metal container body serves as the main structural element, with an outer composite layer of waterproof breathable membrane, rock wool or polyurethane insulation, and interior decorative panels, forming a multi-layer functional 'building envelope'. This design effectively addresses Wuchuan's hot summers and cold, damp winters, reducing energy consumption for air conditioning or heating.
2. Passive Energy-Saving Design: Window positions and sizes are analyzed based on local solar trajectories, utilizing winter sunlight for warmth and reducing direct summer sunlight through eaves, sunshades, or adjustable external shading devices. Natural ventilation paths are pre-designed, with building orientations and module gaps optimized through airflow simulation to maintain indoor comfort with minimal mechanical energy consumption.

II. Safety Hazards and Preventive Measures

The fire risk of temporary container houses primarily stems from material and structural characteristics:

1. Material Hazards: Some illegal structures use flammable sandwich materials such as polystyrene and polyurethane foam, which melt and drip at 80°C, producing highly toxic combustion products and spreading fires rapidly. The iron sheet enclosure makes firefighting difficult.
2. Preventive Requirements:
   • Filling Materials: Must use Class A fire-resistant materials such as rock wool boards and fireproof cotton, with fire resistance limits meeting construction site fire safety standards.
   • Fire Source Management: Maintain safe distances between heat/fire sources and the houses, and designate isolation zones for open flame operations.
   • Electrical Safety: Protect wires with sleeves, use metal galvanized boxes for sockets and switch boxes with exposed installation, and equip both interior and exterior with simple firefighting equipment.
   • Spacing Requirements: Maintain at least a 6-meter safety distance between houses to prevent unauthorized construction.
