AI Technical Summary
Existing residential structures have problems such as weak seismic resistance, insufficient durability and stability, high carbon emissions and poor environmental protection. Traditional light steel structures have insufficient thermal insulation performance and stability issues. Fast-growing wood has low density, is easy to deform, and has weak corrosion resistance, making it difficult to use as the main structural component.
Cold-bent thin-walled steel is combined with fast-growing wood to form a steel-wood composite structure, which is connected by screws, bolts and metal connectors to achieve full prefabrication and assembly. Screw pile foundations are used instead of traditional concrete pouring, combining the advantages of light steel and fast-growing wood to provide high strength, thermal insulation performance and construction efficiency.
It achieves lightweight structure, efficient construction, reliable connection, environmental protection and sustainability, reduces material costs and carbon emissions, is suitable for low-rise buildings, especially village and town residences and small public buildings, and has good earthquake resistance and deformation resistance.
