Abstract

There are 268 pieces of super long steel hangers on the façade of the curtain wall project of Xi’an Silk Road International Convention and Exhibition Center. A single piece of steel hanger is 26m~44m long and 7t~34t heavy. The difference between this project and the conventional construction method of curtain wall lies in that during the installation of steel hangers, the complex deformation of the main steel structure can make it difficult to accurately install steel hangers. The construction steps are simulated with SAP2000. The simulation defines 84 construction steps. After an accurate calculation of the deformation of the main steel structure that each piece of steel hanger must adapt to, the super long steel hangers are assembled on site. The overhanging end of the metal roof is about 5m~20m from the mounting axis of steel hangers, so the conventional process of installation from up to down cannot be applied. A 180T crawler crane is utilized for overall lifting and installation on the side. This is a new construction method of curtain wall that can control the installation accuracy within 5mm, ensure the flatness of the structural façade, improve the construction and installation efficiency, and guarantee the construction safety. It can provide a technical reference for similar large-scale curtain wall projects in the future.
