Abstract:

Qingdao University City Library project, located in a coastal area, employs a pyramidal unit metal roofing system designed to overcome the deficiencies in wind resistance, waterproofing, and aesthetics found in traditional roofing systems. This roofing system comprises 302 triangular cones and features significant slopes with low central drainage, thus demanding high standards for waterproofing and wind resistance. The project utilized BIM technology for in-depth design and incorporated dual-layer waterproofing and dual-path wind resistance technologies to optimize structural nodes and connection methods, and significantly enhanced the roof’s waterproofing and wind resistance, while also ensuring the overall visual appeal of the roofing design. The comprehensive use of these technologies not only ensured the roof was completely leak-proof but also successfully achieved a practical and aesthetic integration of the library’s metal roof.
