The design concept of hyperboloid special-shaped building is realized by using the complementary advantages of the two systems, ingeniously using the idea of local overall force, a non keel metal sunshade with variable cantilever size is designed.This design method not only solves the problem of splicing curved plates, but also ensures the various performance of the curtain wall. The aluminum plate is processed into an integrated special-shaped plate in the factory and installed on site, which improves the accuracy of the modeling lines of the whole building, avoids the impact on the insertion and installation of the window unit, and improves the accuracy of the facade modeling as a whole.And the application and importance of rhinoceros in solving modeling and process data extraction in special-shaped complex curtain wall engineering.展开更多

Due to its external charm and internal simplicity, with the development of society, the progress of science and technology and the improvement of stone mining and processing technology, stone has developed from the past structural materials to the main building decoration materials. Secondly, stone itself has strong aesthetic effect and strong durability,Compared with the glass curtain wall, there is no light pollution. In the process of stone processing and production, craftsmen give full play to human wisdom and make full use of fire burning technology and polishing technology to endow stone with various forms of beauty.
