Modern antique architecture is mainly based on reinforced concrete and steel structure. While inheriting the characteristics of traditional ancient architecture, it changes the stress system of traditional Chinese ancient architecture which is mainly composed of wood structure, and takes reinforced concrete structure and steel structure as the frame, making the whole building have classical appearance, superior structural performance and good durability. The Tea Culture Museum building group adopts a large number of Dougong components and wood-concrete structure connection technology, with complex nodes. Through analysis and summary, a series of key construction technologies such as concrete structure, Dougong structure and decoration of large-scale ancient Song Dynasty buildings are formed. Through this comprehensive construction technology, construction safety is ensured, construction quality is improved, and construction progress is accelerated. It has obtained remarkable economic and social benefits, and has important reference and guiding significance for similar projects, and has broad application prospects.
