Three-Story Installation of Container Houses
The three-story installation of container houses requires focused attention on three core aspects: structural design, material selection, and construction implementation.
Structural Design: Priority should be given to resolving issues related to inter-story force transmission and overall anti-overturning. Customized modular structural designs are adopted, utilizing specialized connectors to ensure robust connections between container units and between container units and foundations. For horizontal splicing, high-strength carbon steel connectors are selected, which conform to the specifications of container corner fittings and are equipped with multiple screw holes to ensure stable splicing. For vertical stacking, through-type connectors are used, which penetrate the corner columns of the upper and lower container units and are fixed with high-strength screws at multiple points, effectively transmitting inter-story forces and enhancing overall structural stability.
Material Selection: The base material for the container body should be Q235B high-strength steel, which offers excellent load-bearing capacity to meet the demands of three-story container houses. In the fastening process, ordinary carbon steel screws are replaced with high-strength galvanized screws. These high-strength galvanized screws possess superior tensile strength and corrosion resistance, ensuring the durability and stability of connection points. Additionally, all connectors and screws must undergo galvanized anti-rust treatment to further enhance their corrosion resistance and extend their service life.
Construction Implementation: Construction should be carried out based on standardized procedures. Initially, foundation leveling and positioning are required to ensure the flat placement of the bottom container unit, laying a solid foundation for subsequent construction. After the foundation passes inspection, the bottom container unit is spliced using specialized tools to precisely align the custom connectors with the corner fittings. Once the holes are aligned, reinforced screws are inserted and tightened to the specified torque using a torque wrench to ensure splicing quality. Furthermore, innovative techniques can be adopted, such as 'slimming down' the container beams by using 6mm steel plates bent into shape instead of heavy square tubes to reduce structural weight; pre-fabricating large integrated modules in the factory for on-site overall lifting and inter-story connection to improve construction efficiency; and using uncoated zinc-magnesium-aluminum plates for interior walls to reduce VOC emissions and provide corrosion resistance, moisture resistance, and 'self-healing' capabilities.
