Container House Production Requirements
Key aspects to consider in container house production include structural design, material selection, ground treatment, installation techniques, and performance testing.
Structural Design: Container houses mainly come in two types: welded integral containers and bolt-connected assembled containers. Welded containers offer good integrity and strong resistance to deformation, making them suitable for frequent lifting and movement. Assembled containers are connected by standard panels using bolts, requiring secure fastening at each joint. The wall thickness of the steel columns and bottom beams typically ranges from 1.5 mm to 3 mm, with thicker walls providing greater load-bearing capacity but also increasing the self-weight.
Material Selection: The coating process on the container surface affects its corrosion resistance. Hot-dip galvanizing provides a longer corrosion-resistant lifespan than cold-dip galvanizing, especially in areas with significant temperature variations between day and night and humidity changes, where the coating quality directly determines the rusting rate of the container.
Ground Treatment: A uniform load-bearing foundation is required for container houses. After removing loose soil and debris from the ground, the original soil layer should be compacted. For long-term fixed use, a concrete strip foundation should be poured, with a recommended width of 30 cm to 50 cm and a depth determined by the local frost depth. The top surface of the foundation should have a levelness error of no more than 5 mm. For short-term use, prefabricated concrete pads or steel plates can be used, with a spacing of no more than 2 m between pads and a crushed stone leveling layer laid underneath.
Installation Techniques: During lifting, sufficient load-bearing steel cables should be used to ensure that all lifting points are subjected to synchronous force, avoiding unilateral force that could cause container distortion. After the container is placed, check the fit between the bottom beam and the foundation pad. If there is local suspension, it should be padded with thin steel sheets, and the levelness error should be controlled within 2 mm per meter.
Performance Testing: The container house should be tested for airtightness, thermal insulation, waterproofing, fire resistance, and moisture resistance to ensure compliance with usage requirements.
