Prefabricated House Curved Roof

The curved design of prefabricated houses is mainly reflected in the application and manufacturing process of prefabricated curved roof components.

Application Examples

In practical projects, prefabricated curved roof components have a wide range of applications. For example, the Lijiang Dahefang project undertaken by Guangxi Construction Engineering Rail Transit Prefabricated Building Industry Co., Ltd. adopted prefabricated curved roof components. These components are large in scale, approximately 12 meters long, 8 meters wide, and covering a total area of about 100 square meters. The application of such large-scale prefabricated curved roof components not only demonstrates the maturity of prefabricated building technology but also brings a unique aesthetic appeal to the building's exterior, meeting diverse architectural design needs.

Manufacturing Process

• Precise Design: The manufacturing of curved roofs begins with a precise design phase. During this process, three-dimensional modeling technology is used to construct an accurate model of the roof, accompanied by mechanical analysis. Through mechanical analysis, it is ensured that the curved roof has sufficient safety and stability when subjected to various external forces such as wind loads, snow loads, and its own weight, thereby safeguarding the building's usage safety.
• Process Deepening and Disassembly: After the design model is completed, the process moves into the deepening and disassembly phase. In this stage, the complete roof structure is disassembled into units or components that are convenient for factory prefabrication, transportation, and on-site installation. A reasonable disassembly method can improve production efficiency, reduce transportation costs, and facilitate on-site assembly and installation work.
• Material Processing: Based on the detailed drawings, large CNC cutting equipment is used to precisely cut steel plates into the required shapes. For curved components, the precision of edge cutting is extremely high, as any minor errors can affect the curvature and overall quality of the components.
• Bending and Rolling: This is the core process for manufacturing curved components. Different bending processes are adopted for steel sections and plates of various specifications and curvature requirements. For example, large hydraulic pipe benders or steel section bending machines are used to bend steel sections, while plate rolling machines are used to roll curved steel plates. Through these professional equipment and techniques, the curvature and shape of the components can be precisely controlled to meet design requirements.
