Container Cargo House Structure
The structure of container cargo houses primarily employs steel frames and modular design, constructed through the combination of standardized containers, featuring high strength, rapid assembly, and functional integration. The structural types and functional designs vary depending on specific uses. Below is an analysis of two typical structures:
1. Box-type House: Standard Modular Structure with Steel Frame and Bolt Connections
The box-type house uses standardized container units as its basic building blocks, with a main structure made of high-strength steel frames connected by bolts to secure the modules. This structural form inherits the industrial standardization advantages of traditional containers, with uniform container sizes (such as 20-foot and 40-foot), facilitating transportation and stacking. The steel frame not only provides structural support but also forms detachable nodes through bolt connections, enabling rapid assembly and disassembly of the house, suitable for temporary buildings, emergency shelters, and other scenarios. Additionally, the container surface is typically treated with anti-corrosion coatings to extend its service life; the interior space can be flexibly expanded by adding or removing container units to meet different scale requirements.
2. 40-foot Double-wing Folding Container House: Lightweight Steel Structure with Functional Integration and Variable Space Design
This type of house features a lightweight steel structure as its main frame, with wall panels made of rock wool sandwich panels, offering thermal insulation, fire resistance, and heat preservation. Its core innovation lies in the ability of the side walls to flip outward and expand the space through mechanical structures: after expansion, the interior area can nearly double, forming layouts such as bedroom + living room or open-plan studios, adapting to various scenarios like residential and office use. In terms of functional integration, the walls are embedded with strong and weak electrical interfaces and equipped with concealed wire channels, ensuring electrical safety while avoiding unsightly exposed wiring. The use of lightweight steel reduces the overall weight, facilitating transportation and lifting, while the rock wool sandwich panels, filled with non-combustible rock wool, effectively block the spread of fire, enhancing safety.
Summary of Structural Advantages
The structural design of container cargo houses embodies the concepts of industrialization and modularization: steel frames provide high-strength support, and bolt connections simplify the construction process; the combination of lightweight steel structures and rock wool sandwich panels balances lightweight design with functionality; the expandable side walls and embedded interfaces enhance spatial adaptability and usability. These features make them widely applicable in temporary buildings, mobile offices, disaster relief, and other fields.
