As the requirement for architectural flexibility and tension increases, many important public places, such as office buildings, shopping malls, stadiums and libraries adopt complex curved exterior design, however, it also increases the difficulties of construction. Mobius ring hyperbolic special-shaped curtain wall installation and construction technology is proposed in the library of Qingdao University City, based on the spatial positioning of 3D control network components, basket soft package technology and curtain wall deepening and turning technology, which effectively improves the accuracy and reliability of components, increases the installation accuracy of hyperbolic special-shaped curtain walls, reduces the destruction rate of finished products.
