Iron Sheet Container House
The iron sheet container house is a temporary or long-term residential building unit transformed on the basis of container modules. Its design, functions, and application scenarios have the following characteristics:
1. Structural Design and Functional Optimization
The iron sheet container house is not simply using containers directly as houses. Instead, it undergoes secondary design from three dimensions: structural mechanics, material thermodynamics, and assembly processes. For example, the Baotou Camp Container House Company solves the problem of insufficient floor stiffness caused by the large spacing between the longitudinal beams of the traditional container's bottom frame by adding C-shaped steel purlins between the bottom beams, enabling the stacked three-layer container to maintain structural stability. At the same time, a broken-bridge lining structure is adopted (hard polyurethane foam is filled between the steel frame and the inner wall panel, and rubber thermal insulation pads are installed at the connections of the keels), reducing the cold-bridge and heat-bridge effects of the metal container walls. This reduces the indoor-outdoor heat exchange efficiency by about 40%. In winter without heating, the indoor temperature can be 8 to 10 degrees Celsius higher than the outside, reducing dependence on heating energy consumption.
2. Material and Environmental Protection Characteristics
The core value of the iron sheet container house lies in the full life-cycle recycling of materials. Taking a standard 20-foot container as an example, its steel consumption is about 1.2 tons, while the carbon emissions of a one-time poured concrete temporary house of the same area are 2.3 times that of the container house. In addition, after shot blasting and rust removal, the container body surface is sprayed with a zinc-rich primer and a polyurethane topcoat, which can maintain an effective service life of more than 15 years in the windy and sandy environment with large temperature differences in northwest China, further reducing resource consumption.
3. Application Scenarios and Customization
Iron sheet container houses are widely used in construction site dormitories, field operation houses, office houses, temporary houses in tourist attractions, and rental houses. For example, the Nagoya Asian Games once used container houses as athlete accommodation facilities. Each unit house was composed of two households, planned as a two-bedroom and one-living-room layout, providing accommodation for three people, equipped with wooden decorations, toilets, bathrooms, refrigerators, washing machines, and air conditioners. The Baotou Camp Container House Company provides on-demand customization services, covering many places in Inner Mongolia, with on-site installation and sufficient supply.
4. Safety and Fire Hazards
Although the iron sheet container house is convenient, some products have fire safety hazards. For example, to save costs, some construction sites use flammable materials such as polystyrene and polyurethane foam as core materials. These materials melt, deform, and drip at 80 degrees Celsius, burn rapidly, and are highly toxic. Once the fire spreads, it can easily lead to collapse and increase the difficulty of firefighting. Therefore, it is recommended to use Class A fire-resistant materials such as rock wool boards and fire-resistant cotton to make container houses, maintain a safety distance of at least 6 meters between container bodies, and equip them with simple firefighting equipment.
