Container House Design Technology
Container house design technology primarily involves multiple aspects such as structural systems, material selection, thermal insulation, connection nodes, surface corrosion protection, and energy integration.
Structural Systems: Container houses are based on standard containers but often utilize factory-prefabricated modular box units. The main frame is typically welded from hot-dip galvanized square steel, with commonly used specifications including 100×100mm and 80×80mm galvanized square tubes to ensure structural stability. Some designs also optimize load-bearing structures by adding C-shaped steel purlins, enabling the boxes to remain stable even when stacked in multiple layers.
Material Selection: Wall panels often use galvanized aluminum-zinc color steel plates combined with thermal insulation materials such as rock wool, glass wool, or polyurethane, ensuring both structural strength and excellent thermal insulation performance. The selection of roof and wall materials also emphasizes weather resistance and corrosion resistance to adapt to various harsh environments.
Thermal Insulation: To address the thermal bridge effect of metal box walls, a broken-bridge lining structure is adopted, where hard polyurethane foam is filled between the steel frame and interior wall panels, along with rubber thermal insulation pads to effectively reduce heat transfer efficiency. Some designs also employ a multi-layer thermal insulation system, such as high-density polyurethane insulation layers combined with underfloor heating and air conditioning dual heating systems, achieving ultra-low energy consumption building standards.
Connection Nodes: A dual fixation mode of “wedge-shaped locks + high-strength bolts” is introduced at box connections to ensure a secure and detachable connection. This design not only improves earthquake resistance but also reduces construction waste.
Surface Corrosion Protection: The coating system uses a combination of “epoxy zinc-rich primer + polyurethane topcoat” to effectively extend the service life of the steel structure. Some designs also enhance the corrosion resistance of the frame through hot-dip galvanizing treatment.
Energy Integration: Some container houses deeply integrate photovoltaic power generation with the building, enabling off-grid operation. This design not only reduces reliance on traditional energy sources but also lowers operating costs.
