Container Mobile House Design
The design of container mobile houses requires comprehensive consideration of factors such as structural type, material selection, thermal performance, connection nodes, surface corrosion protection, and spatial functional zoning.
Structural Type Selection: Common structures include welded integral containers and bolt-connected modular containers. Welded integral containers are formed by factory welding, with a direct load path and strong resistance to deformation, suitable for frequent lifting and movement. Bolt-connected modular containers use standard panels connected by bolts, with multiple connection nodes in the load path. When purchasing, it is necessary to check the wall thickness of the columns and bottom beams; the thicker the wall, the greater the load-bearing redundancy, but the corresponding increase in self-weight.
Material Selection: High-strength weathering steel, such as Q355B grade, should be selected. Its yield strength is approximately 30% higher than that of ordinary carbon steel, reducing material usage. The enclosure structure can adopt a three-layer composite construction of 'rock wool-air layer-aluminum-zinc coated steel plate' to enhance thermal performance.
Thermal Performance Optimization: To address the high thermal conductivity of metal containers, a multi-layer construction is used, with the outer layer resisting wind and sand erosion, the middle layer filled with rock wool as the main insulation layer, and the inner layer reducing thermal radiation. Some companies also add an elevated layer at the bottom of the container to block ground cold bridge conduction.
Connection Node Design: In areas with high seismic design intensity, a dual fixation mode of 'wedge lock + high-strength bolt' can be introduced at the connections to enhance seismic adaptability.
Surface Corrosion Protection: The coating system uses a combination of 'epoxy zinc-rich primer + polyurethane topcoat' to extend the service life of the container.
Spatial Functional Zoning: The fixed size of the container forces designers to adopt a functional overlay strategy, such as compressing the kitchen and bathroom to one end of the container to form a wet area, and achieving day-night functional switching in the living and sleeping areas through furniture variability.
