Container Mobile House in Baotou

Container mobile houses in Baotou have significant characteristics in terms of materials, structure, and functionality, and are widely applied.

Materials and Structure:

• Steel Selection: Some enterprises in Baotou use high-strength weather-resistant steel (such as Q355B grade) as the main frame of the container body. The yield strength is approximately 30% higher than that of ordinary carbon steel. When the length-to-width ratio of a single container body is close to 2:1, a self-balancing system can be formed through the rigid connection of corner fittings and side beams, reducing the need for additional reinforcement components and lowering material usage by about 15%.
• Enclosure Structure: A three-layer composite structure of "rock wool - air layer - aluminized zinc plate" is adopted. The rock wool layer is 75 to 100 millimeters thick, with a thermal conductivity lower than 0.040 W/(m·K). The 5-millimeter air layer in the middle inhibits convective heat transfer. The overall heat transfer coefficient (U-value) is lower than 0.5 W/(m²·K), reducing the risk of condensation and extending the service life of the steel structure.
• Connection Nodes: For geological conditions with a seismic fortification intensity of 7 degrees, a dual-fixing mode of "wedge-shaped lock + high-strength bolt" is introduced. The wedge-shaped lock is made of 45# steel through heat treatment, with a bevel angle of 15 degrees. It generates a self-locking effect under horizontal shear force. In simulated 8-degree rare earthquake tests, the displacement is controlled within 3 millimeters, which is about 40% better than the deformation amplitude of conventional welded nodes, and it is convenient for secondary relocation and repeated assembly.

Functionality and Application:

• Environmental Protection and Recycling: The steel consumption of a container house is approximately 1.2 tons per standard 20-foot container. Its carbon emissions are only 1/2.3 of those of traditional concrete temporary houses, and the disassembly and assembly loss rate is controlled within 5%, significantly reducing construction waste generation.
• Integrated System: Some products are equipped with a self-circulating sewage system. For wilderness camps without water and electricity, a sewage collection tank and a gravity separator are installed at the bottom of the container body to separately treat gray water (from bathing and washing) and black water (from toilets).
• Application Scenarios: They cover multiple places in Inner Mongolia, including Baotou, Hohhot, and Ordos, and are used for on-site accommodation, camp dormitories, temporary offices, etc. They can be customized on demand, installed on-site, and have sufficient supply and stable delivery.
