Assembled Container House Skeleton

The assembled container house skeleton follows the principles of modular construction, utilizing standardized components and achieving overall structural assembly through factory prefabrication and rapid on-site assembly. The core process can be divided into three stages: design decomposition, factory prefabrication, and on-site assembly, with specific key points as follows:

I. Design Decomposition Stage
The container house skeleton needs to decompose the overall structure into standardized modules, typically including six components: the bottom, top, and four sides. The design must adhere to modular construction principles, ensuring standardized dimensions and interfaces for each component to fit automated production lines. For example, a domestic steel structure modular intelligent production line divides the house into six components, which are simultaneously produced on multiple sub-production lines and finally assembled into a complete box at the end of the production line, with a daily production capacity of up to 50 modules. The decomposition design must also consider transportation constraints, ensuring that the dimensions of individual modules comply with container transportation standards to reduce logistics costs.

II. Factory Prefabrication Stage
The skeleton production employs high-precision automated production lines, with welding, assembly, and grinding robots working in tandem to ensure manufacturing precision is consistently controlled within 1-2 millimeters. The main structure typically uses a steel frame paired with fire-resistant rock wool sandwich panels, integrating insulation, fire prevention, sound insulation, and waterproofing functions. For example, an Australian project adopted steel structure modular housing, with all preliminary processes (including plumbing, decoration, and soft furnishings) completed in the factory. Once the modules arrive on-site, they only need to be connected to utilities for occupancy. The factory prefabrication model shortens the construction cycle by more than half compared to traditional methods and significantly reduces construction waste, dust, and noise pollution.

III. On-site Assembly Stage
On-site assembly is completed in a 'building block' manner, constructing the overall framework using supporting steel structure roof trusses and other scattered components. For example, in the Australian project, once the modules arrived at the port, they were quickly combined with steel structure roof trusses to form the building framework, with only the connection of utilities pipelines required on-site for completion, taking just a few days in total. The assembly process relies on standardized interface design, with modules connected via bolts or clips without the need for welding, improving construction efficiency and reducing safety risks. Some projects adopt adjustable movable house frames, supporting repeated disassembly and relocation, further expanding usage scenarios.

Material Selection and Structural Optimization
The skeleton material is primarily galvanized thickened steel, with some projects using C-shaped steel or light steel structures, achieving rapid assembly without welding through screw connections. For example, a container house frame accessory adopts a galvanized thickened design, paired with screws for assembling container frames, offering a discount on the first order and free shipping, combining material guarantees with construction convenience. In terms of structural optimization, modular design supports complex forms such as two-story residential steel structure container villas. Through prefabricated flat-packed movable small house frames, modular housing can be flexibly expanded.
