In recent years, the stone slab dry hanging process has been developed and promoted. The principle is to set the main force point on the main structure, and fix the stone on the building through the metal hanging piece to form a stone decorative curtain wall. At present, the specific practices of dry hanging of various engineering stones vary from place to place. As far as the fixing technology of the pendant and the main structure is concerned, there are mainly two methods: one is that the shear wall structure can be fixed directly by the expansion bolt or the embedded iron piece, and the other is the light wall structure of the frame. The wall can not directly fix the hanging piece, and the hanging piece needs to be fixed by installing the metal skeleton; the metal skeleton is divided into two types: the steel frame and the aluminum frame. The former is low in cost, but needs to be galvanized and anticorrosive. Due to the need to use thicker or aircraft materials, the cost is higher. From the point of view of the fixing method of the board, there are two general types: one is the bolt-type fixing method, and the main components are pins, pallets, bolts, pads and angles, and various components. The model is determined by the weight of the stone, the regional wind load and the seismic load. The structure is: First, the angle steel is bolted to the skeleton or the wall, and the pallet is fixed with the angle steel, and the stone is connected to the pallet through the pin. The hanging piece can adjust the plate up and down in a small range to ensure the uniformity of the plate seam and the flatness of the board surface, and the other is the back-cut dry hanging, also called the stress-free anchoring dry hanging, the specific method is a group The bottom extension anchor is supported by a convex joint and a stone joint and supported by a metal frame, which has great advantages in terms of safety, durability and convenience. According to the treatment method of stone joint seam, one is not separated from the seam, and the plates are naturally connected. The defect of this method is that the expansion and contraction of the sheet is limited due to the temperature difference, and it is not suitable for wide use in the outer wall surface, and the second is the seam. The gap of the sheet is usually 5~8mm, which is generally filled with foam strips and sealed with weather resistant silicone rubber. The main advantages of the stone slab dry hanging method are three: First, it can effectively avoid the phenomenon of hollowing, cracking and falling off of the traditional wet-rolling process, which obviously improves the safety and durability of the building; second, it can completely avoid the tradition. The phenomenon of whitening and discoloration appearing on the surface of the wet-laid process is conducive to keeping the curtain wall clean and beautiful. Thirdly, it improves the working conditions of the construction personnel to a certain extent, reduces the labor intensity, and helps speed up the progress of the project. For example, the Taiye City Anye Building completed in 1999, the building area of ​​26400 square meters, the total height of 98.2m, the façade granite curtain wall of about 7,800 square meters, all using plug-type dry hanging method construction. The granite light board is selected from 635# stone material in Nan'an County, Fujian Province, and the 635# fire burning board is used in the grid color. In the light wall of the frame, the 8# channel steel is the main keel, and the L50X5 angle steel is the skeleton for the secondary keel. The skeleton connection is welded. The weld height h=6mm, all the skeletons have been rust-proof. The components of the pendant are made of stainless steel, and the seams are separated by a seaming method. The horizontal and vertical are 8mm. After being uniformly filled with foam strips, they are sealed with weatherproof silicone rubber imported from the United States. The construction process of the granite curtain wall of the project is: measuring the elastic line → installing the skeleton → installing the hanging piece → fixing the plate → adjusting → sealing the sealant → cleaning → acceptance. In order to ensure the quality of the project, during the construction process, special attention has been paid to the measurement of the release line, and the deviation of the main structure is controlled, distributed and digested, so that the verticality and flatness of the entire skeleton are strictly controlled within the allowable range. For the veneer, the length-width deviation is ±0.5mm, the hole deviation is 0.5mm, and the hole depth deviation is 2mm. The overall project of the building was awarded the 1999 China Construction Engineering Luban Award for its excellent quality.
