Steel Frame Prefabricated House Construction

Steel frame prefabricated house construction adopts a steel structure modular building technology system, which is an industrialized building method with steel structures as the main body. Details are as follows:

I. Basic Units
The basic units are standardized prefabricated modular spatial building modules. Most of the work for these modules is completed in the factory, integrating architectural, structural, mechanical and electrical, and interior decoration functions. Through factory prefabrication, highly standardized production can be achieved, ensuring the dimensional accuracy and functional integrity of each module, and laying the foundation for subsequent on-site assembly.

II. System Characteristics

1. Performance Advantages: Light self-weight, good seismic performance, and high recyclability, aligning with the direction of building industrialization and green development. The steel structure itself has high strength and good ductility, effectively absorbing seismic energy and reducing structural damage. At the same time, steel can be recycled and reused, reducing resource consumption.
2. Construction Efficiency: The factory prefabrication rate can reach over 90%, enabling a shortened construction period and reducing on-site construction waste and noise pollution. After the modules are produced in the factory, they are transported to the site for direct assembly, avoiding wet operations and cross-operations in traditional construction, significantly improving construction speed.
3. Quality Control: Transforming uncontrollable on-site construction into controllable factory manufacturing, with quality, performance, and delivery times all under control. The factory production environment is stable, and the process flow is standardized, effectively avoiding quality issues caused by human factors and ensuring the overall performance stability of the building.

III. Construction Process
When the upper structure of the building adopts a frame structure for load-bearing, square or rectangular individual foundations are often used. These foundations are not deeply buried, use less material, and have a short construction period, making them the preferred foundation form for frame structures. After that, the production of module units is completed in the factory, and then they are transported to the construction site for combined installation. The modules are connected into a whole through reliable connection nodes to form a complete building structure.

IV. Application Status
Currently, this technology system is an important branch in the field of prefabricated buildings. With the successive introduction of relevant standards, the specialized technical standard system for modular buildings has become increasingly mature. The application of the technology has achieved a breakthrough from low-rise temporary buildings to multi-story and high-rise permanent buildings. High-rise projects have been implemented in many places such as Beijing, Guangdong, and Shanghai, demonstrating broad application prospects.
