Container House Structure
The structure of a container house mainly includes key components such as steel structural frames, enclosure structures, connection nodes, anti-corrosion coatings, and internal layout designs.
The steel structural frame serves as the core supporting structure of the container house, typically made of high-strength steel, such as Q355B-grade weathering steel. This type of steel has a high yield strength, ensuring the house remains structurally stable under extreme conditions, such as strong winds and earthquakes. The frame design must consider the load transfer path, ensuring that roof loads are transmitted through sidewall columns to the base beams and then evenly distributed to the ground. Some houses also employ a fully steel structural frame, forming a self-balancing system through rigid connections between corner fittings and side beams, reducing the need for additional reinforcement.
The enclosure structure is responsible for providing insulation, heat resistance, and waterproofing functions. A common enclosure structure adopts a three-layer composite construction of "rock wool-air layer-aluminum-zinc coated steel plate," with an appropriately thick rock wool layer and a low thermal conductivity coefficient, effectively limiting heat transfer. The intermediate air layer suppresses convective heat transfer through a closed cavity, improving overall heat transfer performance. Additionally, the enclosure structure must consider condensation control, especially in regions with large temperature differences, by adjusting the coating formulations on both sides of the panels to reduce the probability of condensation.
The design of connection nodes is crucial for the seismic adaptability of the house. A dual-fixing mode of "wedge-shaped lock + high-strength bolts" is adopted, which generates a self-locking effect under horizontal shear forces, improving the seismic performance of the nodes. This detachable connection method also facilitates the secondary relocation and repeated assembly of the house.
The anti-corrosion coating is used to protect the steel structural frame from corrosion, extending the service life of the house. The coating system typically employs a combination of "epoxy zinc-rich primer + polyurethane topcoat," with the primer protecting the base metal through the sacrificial anode principle and the topcoat resisting wind and sand erosion.
The internal layout design is flexibly adjusted according to actual needs, supporting on-demand splicing and combination, and can be easily expanded into double occupancy dormitories, small offices, or meeting spaces, etc.
