Abstract:The construction of traditional architecture needs urgent reform, and the integrated architecture is an effective way to solve the problem. Firstly, this paper discusses the concept of integrated building. It then analyzes some typical integrated building cases,puts forward its characteristics as design integration, production industrialization, construction assembly, lightweight structure, space intensification, decoration integration, management information and overall greening, etc., and classifies the integrated building as timber structure, cold-formed steel structure, container structure, light steel frame structure,composite structure, etc. Finally, it raises attention to the overall design of integrated architecture, improvement of the building material system, and optimization of component production in order to promote the integration of building decoration and actively promote its theoretical maturity and practical development.
