With the development of curtain wall technology, along with the demand of artistic expression of architecture of curtain wall in China, some complex three-dimensional space shapes are increasingly used to the exterior of building. Among them, the construction of complex architecture formed by stone curtain wall system is extremely difficult. Currently, back-latching and hanging are the two most commonly used stone panel installation forms. The stone panel is a multi-point force bearing structure and the panel thickness of general stone curtain wall is about 30mm. In order to achieve architecture space shaping, on the one hand, stone panel thickness needs to be added at structural design. As the curtain wall dead weight is increased and the processing technology is more complex, the system safety and practicability can hardly be both considered. On the other hand, during installation on site, installation of stone panel for architectural shaping curtain wall is very difficult to control in terms of precision and the final installation quality and overall effect will be affected. In order to realize the architect’s bold conceiving on the stone shaping of the commercial annex building of Chengdu Yintai Center, this project adopts a stone curtain wall system simply supported on four sides, greatly improving the mechanical properties of stone panel under the same condition. The lock block fastening method assures the installation precision. The construction tasks are completed highly efficiently with high quality, perfectly showing the unique visual effect of the stone curtain wall.
