Dry hanging marble stone is a kind of construction technology of the external wall of the building. The process is the use of corrosion-resistant bolts and corrosion-resistant flexible connectors. It has reached a new level in appearance, durability, not easy to change color and flatness. It overcomes the shortcomings of the traditional wet stone method and is increasingly used in the exterior wall decoration of large-scale civil buildings. The marble, granite, artificial marble and other decorative stone are directly hung on the outer surface of the building knot, leaving 40-50mm cavity between the stone and the structure. The veneer made by this process allows the proper amount of displacement under the action of wind force and seismic force to absorb part of the wind force and seismic force without cracks and shedding. Then the following characteristics and talk about hanging marble dry hanging marble construction process it. Introduction to dry marble Dry hanging marble is a new type of building exterior wall construction technology. This method uses metal hanging pieces to hang marble stone directly on the wall or hang it on the steel frame without re-grouting. The principle is to set the main stress point on the main structure, and fix the stone on the building through the metal pendant to form a stone decorative curtain wall. Dry marble is easy to construct, easy to guarantee construction quality, clear and tidy grid, good overall look and feel, and some frames can be constructed without masonry infill walls. Dry marble is mainly anchored on the stone by the frame and fixed on the building body. It will not cause accidents due to loosening and cracking due to factors such as vibration, temperature difference, and glue aging. The biggest difference between dry marble and wet or dry grouting is that cement mortar (dry) and hanging structure are not used. Different types of stone can be selected according to the environment, dry hanging area and other factors. Stones of the building facade are selected from natural marble and granite stones, which can achieve conditions of aging resistance, temperature resistance, rigidity, and high safety factor. Dry hanging marble features The dry hanging marble process utilizes corrosion-resistant bolts and corrosion-resistant flexible connectors to hang marble, granite, and other facing stones on the outer surface of the building structure, leaving a 40- to 50-mm cavity between the stone and the structure. . The veneer made by this process allows the proper amount of displacement under the action of wind force and seismic force to absorb part of the wind force and seismic force without cracks and shedding. When the wind seismic force disappears, the stone is also reset with the structure. 1. It can effectively prevent the infiltration of pigments such as salt and alkali in grouting and improve the quality of decoration and perception. 2. It can effectively avoid the phenomenon of hollowing, cracking, falling off and other phenomena of the traditional wet-plating process, which obviously improves the safety and durability of the building; 3. To a certain extent, improve the working conditions of construction workers, reduce the labor intensity, and thus accelerate the progress of the project. 4, can be used with glass curtain wall or large glass windows, metal veneer installation process and other supporting applications. 5. Compared with the traditional wet operation process, the dry hanging marble process eliminates the grouting process, shortens the construction period, reduces the weight of the building, and improves the anti-seismic performance. 6. It can completely avoid the phenomenon of whitening, discoloration and other phenomena that appear on the surface of the traditional wet-plating process, which is conducive to keeping the curtain wall clean and beautiful; 7, due to changes in seasonal outdoor temperature caused by the expansion and contraction of the outer surface, so that the veneer may fall off, dry hanging marble process can prevent the loss of veneer accidents. Dry hanging marble construction process 1, process flow Layout → Select Marble Plate → Processing, Numbering → Steel Frame Fabrication, Steel Frame Acceptance → Façade Surface Treatment → Wall Framing Line Casting → Steel Frame Fixing → Checking Flatness and Firmness → Marble Fixing → Cleaning Surface and Insertion Sewage → fill seals and sealants → clean → acceptance. 2, process steps 1. According to the requirements of the grid marble's grid grid size, the elevation grid diagram is drawn. When the construction is completed, the sub-grid lines are popped on the wall according to the sub-grid diagrams, and the specifications of the facing stone materials are processed. 2. When the facing base is a frame without a filling wall, a vertical main keel is provided at intervals. The main keel is connected with the base wall or the frame girder by expansion screws and connecting irons. The main keel can be Using channel steel, square steel or angle steel, the material specification of the main keel, the gap between the marble stone and the base layer are taken into consideration. The allowable span of the secondary keel is determined by mechanical calculation, and when the base layer is a wall surface, the main keel may be omitted. The secondary keel is directly fixed on the wall. 3. A keel is provided on each marble transverse joint, and electric welding is used between the secondary keel and the main keel. The size of the secondary keel should be calculated according to the size of the stone specification, considering the weight of the stone it bears, and the wind load. Determined to use L30×3 or L50×5 angle steel 4. A small hole of φ5 is opened at the top and bottom of each piece of marble. The connection between the marble and the sub-keel is connected with the iron and the steel pin. The connection between the connecting iron and the sub-keel is fixed by bolts. The node can make the connection piece. Fine adjustment of the front and rear and left and right positions to adjust the verticality and flatness of the granite. The steel pin generally adopts φ4 galvanized steel or stainless steel. The gap between the steel pin and the granite hole can be filled with epoxy resin or 502 glue. 5, gap handling: dry hanging marble veneer between the plate generally leave 8 ~ 12mm gap, after the completion of the installation of the whole wall, the gap with silicone seal. The color of the silicone can be selected according to the color of the stone. In order to make the silicone even and beautiful, a lightweight foam strip is embedded in the seam before the silicone is used as the backing of the silicone. 6. If the interior wall is decorated with marble, the sub-keel can be directly fixed on the wall, so that the main keel can be eliminated, and the sub keel is connected with the base wall with expansion bolts and connecting iron pieces. Dry hanging marble prices The labor cost is between 50-100 yuan, but this is a very test of the worker's craft. If the craft is good, it can guarantee the damage of the marble panel and reduce the loss. In general, the craft will increase the loss of the panel. As a result, the construction of dry hanging marble requires a price of 400-700/m2. The price of dry-hanged marble consists of keel system, marble panel, stainless steel pipe fittings, can seam sealing material and installation fee. Keel aluminum alloy and steel prices are not the same, the structure also has a size, the price is 100-500 yuan / square meter. The marble panel varies depending on the type and thickness of the stone, ranging from 100-1000 yuan.
