Kaifeng Container Finished House

Kaifeng container finished house is an environmentally friendly, flexible, and convenient temporary or permanent building based on containers. It is widely used in construction site dormitories, offices, commercial, and emergency scenarios, featuring standardization, mobility, earthquake resistance, and fire prevention. However, attention should be paid to fire safety and compliant construction.

I. Basic Definition and Uses

A container finished house takes a standard container as its structural main body and forms a livable or office space through internal modifications such as installing doors, windows, partitions, and pipelines. Its core uses include:

• Construction sites: Serving as worker dormitories, temporary offices, or canteens to meet the rapid deployment needs of construction sites.
• Commercial scenarios: Used for shops, kiosks, cafes, homestays, etc., suitable for creative districts or tourist attractions.
• Emergency scenarios: Acting as disaster relief shelters or field exploration camps to provide quickly built refuge spaces.
• Municipal engineering: Serving as the command center for project departments to adapt to the frequent relocation operation mode.

II. Structural Features and Advantages

1. Materials and Workmanship
   The main body adopts a light steel structure frame and is paired with fire-resistant rock wool sandwich panels as walls, featuring high strength, flame retardancy, and thermal insulation. For example, the walls of Yujiang packing container houses are filled with high-density inorganic fibers, which do not spread when exposed to open flames, and their wind and earthquake resistance have been verified in laboratories.

2. Standardization and Flexibility
   The modular design supports rapid assembly and disassembly. On-site, it can be closed by bolt positioning and corner piece connection. The standardized interface design allows for repeated folding and flat transportation, adapting to the entry needs of narrow sites.

3. Durability and Economy
   The yield strength of the main steel meets the standards, and the service life can reach more than 20 years. It can be reused many times, and the comprehensive cost of a single project is about 30% lower than that of traditional temporary buildings, without the need for secondary construction and construction waste removal.

III. Safety Precautions

1. Fire hazards
   Some low-priced products may use flammable sandwich materials such as polystyrene and polyurethane foam. It is necessary to give priority to choosing Class A fire-resistant houses filled with rock wool panels and fire-resistant cotton. During use, keep away from heat and fire sources, add protective sleeves to wires, and equip with fire extinguishing equipment.

2. Compliant construction
   It is necessary to ensure that the construction materials meet fire safety standards to avoid fires caused by electrical circuit failures. For example, in 2020, a container house in Langfang caught fire due to a circuit failure in the switch, resulting in a burned area of 20 square meters.

3. Spacing requirements
   There should be at least a 6-meter safety distance between container houses to prevent the spread of fire.
