Standards for Container-Based Living Houses
The standards for container-based living houses cover multiple aspects such as dimensions and structure, performance, safety, comfort, and maintenance, as detailed below:
Dimensions and Structure: Residential containers typically maintain standardized and modular characteristics, with dimensions consistent with standard shipping containers, approximately 6 meters in length, 2.4 meters in width, and 2.6 meters in height, although there are also special models that are taller or wider. Their structure is formed by welding high-strength corrugated steel plates, with square steel tube columns inside to support and create a steel frame load-bearing system. This structure offers outstanding resistance to wind and earthquakes, supports rapid assembly and disassembly, and facilitates transportation and reuse.
Thermal Insulation Performance: Thermal insulation is one of the key standards. The ordinary type only has a layer of insulation cotton attached to the wall, suitable for warm regions; the insulated type, on the other hand, is equipped with polyurethane foam boards or rock wool boards on the inner walls, combined with double-glazed vacuum windows, which can maintain indoor temperature even in northern winters, meeting residential needs under different climatic conditions.
Fire and Water Resistance Performance: Residential containers produced by reputable manufacturers must pass multiple tests. Wall materials must meet B1 or A-level fire resistance standards, and the electrical system must be equipped with leakage protection devices to ensure electrical safety. At the same time, waterproofing must be thorough to prevent leakage issues in humid environments, ensuring a dry and safe living environment.
Safety Inspection and Building Standards: Residential containers must undergo safety inspections by relevant authorities and comply with local residential building regulations to ensure structural safety, fire safety, and overall habitability. This is a prerequisite for their legal use.
Comfort Design: Insulation layers, ventilation systems, heating equipment, etc., must be installed to enhance the living experience. Supporting facilities such as water and electricity pipelines, drainage systems, and kitchen and bathroom facilities must be complete to ensure convenience in daily life. In terms of ventilation and lighting, additional windows, skylights, or vents should be installed to avoid a closed environment; for noise isolation, soundproofing materials should be added to reduce external interference.
Service Life and Maintenance: With proper maintenance, residential containers can typically be used for 10 to 15 years. Maintenance includes regularly checking whether the anti-rust paint on welds has fallen off, cleaning the roof drainage ports, adding insulation sleeves to water pipes in winter, etc. If placed permanently and with reduced transportation and handling, their service life can be further extended.
