With the development of exterior wall decoration, people are now increasingly choosing dry hanging methods to decorate the exterior walls. This greatly promoted the development of the dry hanging stone industry. The following is the definition and classification of the 2016 dry hanging stone industry in the report hall. Dry hanging stone industry definition Dry hanging stone, also known as the empty hanging method. It is a new construction technology in the decoration of contemporary decorative materials. The method directly hangs the facing stone on the wall surface or hanging on the steel frame with a metal pendant, and does not need to be grouted and pasted. 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. The veneer made by this process allows an appropriate amount of displacement under the action of wind and seismic forces to absorb part of the wind and seismic forces without cracking and falling off. Dry hanging stone industry classification The construction technology of dry hanging stone as a building exterior wall can be classified as follows according to the fixing method of the board: 1, plug type Through the professional opening device, the edge of the porcelain plate is precisely processed into a round hole, the pin is inserted into the hole, and the porcelain plate is fixed on the keel through the connecting member. Due to the opening of the edge of the porcelain plate, it is easy to collapse, the loss of the porcelain plate is large, the construction process is complicated, and it has been eliminated, and it is basically not used. 2, slotted Through the professional grooving equipment, the edge of the porcelain plate is precisely processed into a groove, the hanging piece is buckled into the groove, and the porcelain plate is fixed on the keel through the connecting piece. Insufficient slotted porcelain curtain wall: high requirements for porcelain plate thickness, general porcelain plate is not less than 15mm thick; easy to collapse when slotting, large loss; need to install steel keel, increase building load, and increase cost; Insulation should be installed separately, thermal insulation installation and curtain wall installation cross construction, safety hazard is large; sheet stress is point bearing, poor seismic performance, low safety factor. 3, back bolt Through the professional drilling equipment, the large and small tapered circular holes inside the porcelain plate are precisely machined, the anchor bolt is inserted into the hole, and screwed into the screw, the bottom of the anchor bolt is completely unfolded, and the tapered hole is matched. Forming a stress-free convex joint that secures the porcelain plate to the keel through the joint Insufficient back-bolt dry hanging curtain wall: steel keel needs to be installed to increase the bearing weight of the building and increase the cost; the heat preservation should be installed separately, the thermal insulation installation and the curtain wall installation cross construction; the safety hazard is large; the stress of the plate is point bearing, Poor seismic performance and low safety factor. Compared with the traditional wet working process, the process eliminates the grouting process, shortens the construction period, reduces the building weight, improves the seismic performance, and more importantly, effectively prevents the penetration of salt and alkali pigments in the grout to the stone. Its decorative quality and look and feel. The traditional veneer with grout as the connection means that the veneer may be detached and deformed due to the seasonal outdoor temperature difference, which may cause the veneer to fall off, posing a threat to personal safety. In contrast, the construction technology of dry hanging stone may be Effectively prevent the occurrence of accidents caused by falling off the veneer. The dry hanging panel installation process can also be matched with glass curtain wall or large glass window, metal veneer installation process and the like. At present, the installation of the inner and outer decorative panels of stone in many large public buildings in China takes the construction technology of such dry hanging stone.
