The stone curtain wall has the unique advantages of nature, thickness, luxury and the like, and the usage amount of the stone curtain wall is in the trend of increasing year by year in China.
The back-tied dry-hanging open type stone curtain wall is a novel stone curtain wall type, is selected by more and more curtain wall companies due to the unique structure of the curtain wall, and is also accepted by people in the building industry. The back bolt dry hanging open type stone curtain wall is characterized in that special drilling equipment is adopted for drilling holes in the back face of a stone panel, then a stress-free bolt is installed and fixed on the back face of stone, then the bolt is connected with an aluminum alloy hanging piece, and the stone panel is dry hung on a building wall body through the connection of the aluminum alloy hanging piece and a framework. Each row of hanging pieces of the open type stone curtain wall corresponds to one steel cross beam, the steel cross beams need to be installed on site, one end of each steel cross beam needs to be welded, the workload of field high-altitude operation is increased, and engineering cost control and time control are not facilitated. The structural form of the open type stone curtain wall allows rainwater, wind and weak sundries to enter the back of the stone panel along with the gaps of the stone curtain wall. If workers can not guarantee that the stress-free bolts (back bolts) on the stone panel can be effectively connected with the hanging pieces in the installation process, the back bolts and the hanging pieces on the stone panel are not firmly connected due to long-term wind and rain infiltration, and the back bolts and the hanging pieces of the stone panel are not firmly connected in the past, so that the stone panel falls off from a building.
