Stone curtain wall: dry hanging: back bolt type Harbin telecommunication building expansion project, Nangang district is located in the downtown area of Zhongshan Road side, 2 floors underground, the ground 2 floors, the total height of the building 99.7m, building area of 32556 square meters, the floor and the walls are made of dry hanging granite fire board finishes, hanging stone area of about 13700 square meters. Back bolt dry hanging stone curtain wall is in the stone back to drill hole and the dovetail convex combination and expanding bolt connected with keel, keel anyway and the metal stents through embedded parts is connected and fixed on the wall. The back plug type external wall hanging stone is a construction technology imported from abroad in recent years. It has the following advantages: First, back bolt dry hanging stone, because each stone has four back bolt type pendant pendant each uniform under the weight of the stone material and stone keel pendant Pendant with large contact area between the corresponding strength and good stability. Therefore, it can be applied to high-rise and super high-rise exterior wall finishes. Second, the back plug type dry hanging stone, because each pendant is bearing stone weight, broken stone is not easy to fall off, and easy to change. Third, the back plug type dry hanging stone surface is clean, not easy to be polluted, and cement mortar bonding, stone surface because of cement slurry erosion, easy
