Container-Based Movable Housing Framework

The container-based movable housing framework is a modular building system centered around a steel frame structure, connecting standardized container units with bolts. Its design integrates the concepts of industrial prefabrication and rapid assembly, offering significant structural advantages and functional characteristics, which can be analyzed from the following aspects:

I. Structural Composition and Material Characteristics

The framework's main body employs a high-strength steel frame, constructed using cold-formed thin-walled steel or hot-rolled steel sections to establish a load-bearing system that ensures structural stability and resistance to deformation. The steel skeletal structure (i.e., the steel frame) serves as the core support, capable of withstanding vertical loads and horizontal wind/seismic forces, meeting the requirements for multi-story combinations. Container units are connected via high-strength bolts, enabling rapid disassembly and reassembly for repeated use, avoiding on-site welding operations, and enhancing construction efficiency and safety. Standardized containers, as basic modules, adhere to international standard dimensions (such as 20-foot and 40-foot container specifications), facilitating transportation and stacking.

II. Modular Building Attributes

This framework falls under the category of modular building products, with its core feature being "factory prefabrication + on-site assembly":

1. Industrial Production: The main building structure, enclosure system (walls, roof), utility systems (electrical, plumbing), and interior finishes are all prefabricated in the factory, forming standardized spatial modules.
2. Rapid On-Site Assembly: Prefabricated modules are joined on-site using bolts or connectors, eliminating the need for traditional wet construction and significantly shortening the construction period. For example, a single-story house can be installed within a few hours, while multi-story buildings can be rapidly expanded through module stacking.
3. Functional Integration: Modules come with pre-installed utilities and finishes, reducing on-site cross-operations, enhancing building quality consistency, and lowering long-term maintenance costs.

III. Core Advantages and Application Scenarios

1. Rapid Deployment Capability: The steel frame and bolt connection design endow the house with a "plug-and-play" characteristic, suitable for scenarios requiring quick deployment, such as emergency rescue, temporary offices, and construction site dormitories.
2. Multi-Story Combination Flexibility: Supported by the steel skeletal structure, modules can be vertically stacked up to 3-4 stories, meeting space expansion needs while maintaining overall structural stability.
3. Movability and Reusability: Container units can be disassembled, transported to new sites, and reassembled, enabling resource recycling and aligning with green building principles.
4. Strong Adaptability: The steel frame structure can withstand harsh environments (such as strong winds and earthquakes), while the enclosure system employs insulation and fire-resistant materials to adapt to different climatic conditions.

IV. Technical Specifications and Standards

The framework design must comply with modular building-related specifications, including performance requirements for structural safety, fire resistance, and sound insulation. The steel frame must undergo bending and shear calculations to verify its load-bearing capacity, while bolt connections must meet torque and tensile strength standards to ensure long-term reliability.
