Abstract:

In view of the special requirement of the outdoor gallery bridge outer curtain wall for NingboInternational Conference Center, the construction technology of complex special⁃shaped GRC curtain wallis put forward. The efficient and reliable installation of GRC curtain wall is ensured by adopting fullyprefabricated construction technology, BIM model deepening technology, overhanging bracket + U⁃shaped groove connection form, and optimization of installation sequence of curtain wall components. Atthe same time, in order to solve the problems of low on⁃site assembly rate, tedious construction process,low construction efficiency and difficult control of construction quality in the design and constructionscheme of traditional special⁃shaped GRC curtain wall structure, a new type sloted connection of special⁃shaped GRC curtain wall structure is proposed. The connection form includes the curtain wall platecarrying skeleton structure and the extended steel corbel + U⁃shaped groove connection joint, which hasthe advantages of simple structure and full prefabricated installation and construction. The finite elementanalysis results show that the proposed slotted GRC curtain wall joint has sufficient connection strength.
