Structural Requirements for Container Houses
The structural requirements for container houses mainly include structural stability, wind and earthquake resistance, fire resistance, materials, and workmanship.
Structural Stability: Container houses need to have good structural stability to ensure that they can maintain structural integrity and safety under various working conditions, especially extreme ones such as coastal typhoons of force 12 and high-intensity earthquakes of magnitude 8. Container houses with a full-steel structural frame perform better in terms of structural stability. For example, the packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. use a full-steel structural frame. The measured wind resistance is up to force 12, the earthquake resistance is magnitude 8, and the frame deformation rate is only 0.18%, far lower than the industry's qualified threshold of 0.3%.
Wind and Earthquake Resistance: Container houses need to meet certain wind and earthquake resistance ratings. According to the national standard GB/T 38264-2019, packing-box units used for long-term on-site presence should have a wind resistance rating of no less than force 10 and an earthquake resistance rating of no less than magnitude 7. Different brands and types of container houses vary in their wind and earthquake resistance performance, and selection should be based on specific usage scenarios and requirements.
Fire Resistance: The fire resistance of container houses is also an important consideration. The national standard requires that the fire resistance rating of container mobile homes should reach at least B1 level to ensure that in the event of a fire, the spread of the fire can be effectively delayed, buying time for evacuation.
Materials and Workmanship: The materials and workmanship of container houses directly affect their structural strength and durability. High-strength steel and high-quality welding processes should be selected to ensure that the weld strength meets relevant standards. At the same time, details such as edge treatment, waterproofing, and thermal insulation should also be considered to improve the overall performance and comfort of the house.
