The dry hanging stone is unfamiliar to those who have not been renovated. The dry hanging stone is a kind of construction process for the external wall of the building. The process is to use corrosion-resistant bolts and corrosion-resistant flexible joints to make granite. , Artificial marble and other decorative stone directly hung on the outer surface of the building structure, stone dry hanging method, also known as empty hanging method. The method hangs the decorative stone directly on the wall surface or hangs on the steel frame with a metal pendant without the need for grouting and sticking. 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. For details, please come with Xiao Bian and introduce to everyone the dry hanging stone and the construction plan of the dry hanging stone on the outer wall . What is dry hanging stone? It is a kind of construction technology of the external wall of the building. The process uses corrosion-resistant bolts and corrosion-resistant flexible connectors to directly hang decorative stone such as granite and artificial marble on the external surface of the building structure. Leave a 40-50mm cavity between. 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. Dry hanging stone implementation method 1, plate cutting. According to the requirements of the design drawing, cutting shall be carried out at the construction site. Since the size of the plate is large, it should be cut with a stone cutter. Care should be taken to maintain the straightness and the rules of the corners of the plate. 2, edging. After the sheet is cut, it can be polished with a portable sander to make the corners smooth. 3, drilling. Adjacent plates are fixed with stainless steel pins and pins are inserted into the side holes of the plate. Aperture Φ5mm, depth 12mm, drilled with an electric drill. As it relates to the mounting accuracy of the plate, it is required that the position of the drill hole is accurate. 4, slotting. Due to the major weight of the large-size stone, besides the steel member is used to hold the lower part of the plate firmly, a supporting fastener must be provided in the middle of the plate to support the weight of the plate. 5, paint waterproof agent. A poly acrylic waterproof coating is applied to the back of the panel to enhance the waterproof properties of the exterior. 6, wall finishing. If the surface of the concrete outer wall has partial projections that will affect the installation of the fastener, it must be flattened and trimmed. 7, bombs. From the structure, the height of the floor and the position of the axis are drawn, the horizontal and vertical control lines of the plate are popped up on the wall surface, and the ash cake is made to control the flatness of the plate installation. 8, wall painting waterproof agent. Since the mortar is not filled between the plate and the concrete wall, a layer of waterproof agent is applied to the outer wall in order to prevent leakage due to material properties or construction quality. To strengthen the waterproof performance of the exterior wall. 9, plate installation. The order of installing the plates is from bottom to top. Two horizontal control lines are pulled from the upper and lower plates at the installation position of the next row of plates on the wall. Plates are installed in place from the middle or the wall surface. First install the first piece as a reference, and the flatness is based on the gray cake set in advance. Hang it straight with a wire and fix it after calibration. A row of plates is installed, and then a row of fasteners is fixed and installed. The plate installation requires four-corner formation and vertical and horizontal seams. 10, the fixed plate. The steel fasteners and the wall body are fixed with expansion anchor bolts. The fasteners are flat steel plates drilled with bolt mounting holes and pin holes, which are adjusted according to the installation distance between the wall surface and the plate. The holes in the fasteners are all elliptical so that they can be adjusted when installed. 11, waterproof seams of sheet joints. The waterproof treatment of the stone facing seam uses sealed silicone caulking. Prior to caulking, a flexible strip of foamed polyethylene material is embedded in the gap as a substrate to control the sealing depth of the seam and to enhance the adhesive strength of the sealant. External wall dry hanging stone construction plan Construction method (1) Measured structural deviation The deviation of the measured structure has very practical significance for the repair of the structure, the secondary design of the plate and the sheet metal processing. The deviation measurement adopts the combination of theodolite's investment measurement and vertical and horizontal thread-hanging method. The thread is used for the hanging thread; the measurement results are recorded in time and the measured results are plotted, and the technical person in charge and the sample-returning personnel are submitted to the secondary design. (2) Secondary design of construction drawings After receiving the complete design institute drawings, they should carefully read and understand the drawings, summarize the issues and promptly exchange opinions with the owners, supervision, design institutes, and quality inspection departments to determine specific practices and clear the construction drawings. The second drawing design of the construction unit shall be submitted to the construction site and the factory for processing orders as soon as possible. (3) Payout The horizontal line of the exterior wall is based on the design axis. It is required that the wall surface of each wall be removed from the wall of the expansion mold or the recessed wall surface after repairing, so that the error of the wall surface from the design axis should not exceed 1 cm. The specific principles of line laying are: designing the vertical alignment of the inner wall axis, designing the elevation of each layer +50cm line and setting the horizontal line up and down, popping the window and the word line of the well and popping the steel keel position line according to the secondary design drawing. Hang a vertical line under each big corner and give a large vertical control line. After completion of the release line, a self-inspection double-track line shall be carried out. After the double-track line is correct, formal inspection shall be carried out again, and the next step may be performed only after passing the inspection. (4) Connector welding and keel installation The connection piece adopts angle steel and structure pre-embedded iron three-face welding. To ensure the durability of the connection part, a welding seam is added to the edge of the angle steel plant, which is actually four-side welding. After the welding is completed, remove the skin and weld the seam hidden inspection according to the regulations. After passing the inspection, brush the antirust paint three times. The fixing position of the connector is determined according to the position of the spring line of the connector, and the method of horizontally following the line, center-to-line, first spot welding, and confirming the correct welding is adopted. Due to the fact that the gaps in the false columns, provocations, etc. due to the structural filling of the hollow block wall or the stone surface are too large, in order to satisfy the exterior facade effect of the architectural design, the steel keel must be attached to the outside of the silicon structure. The steel keel is welded to the structural embedded parts through angle steel joints. The weld requirements and inspections and anti-corrosion practices are the same as above. The connection between the sub-keel and the pendant is made of stainless steel bolts, the sub-keel is used to open the long hole according to the bolt position, and the tongue plate cooperates with each other to realize the position adjustment. The mounting position of the steel keel must meet the requirements of the hanging plate. (5) Pendant installation After the connection piece or sub keel is welded, the stainless steel pendants are connected with stainless steel bolts. Stainless steel pin position, T-type stainless steel pendant position through the pendant bolt holes to adjust the degree of freedom, after the vertical plate is correct, then tighten the bolt, bolt tightening degree is fully flattened by stainless steel spring pad, hidden inspection qualified before the next process . (6) Decorative panel installation According to the drawing practice, the dry hanging plate is connected with the pendant pin and is supported from the bottom up. In principle, the surface of the board is faceted with large noodles, and the corners of the building, Big Horn Yangjiao and Zhuyangjiao, are Haitangjiao. 5mm。 Slot width of the board 60mrn, hole depth 16mm, hole in the outer surface of the plate: polished plate 12.5mm, singe plate 12. 5mm. Plates must be installed with the line, according to the specifications of the leveling, find, find vertical. When the hanging plate is widened, the width of the slot is adjusted according to the requirements of the second design drawing. The plate is first tested and hung. Each plate is leveled by the ruler and then hangs the plate. Before installing the T-shaped pendant, the structural glue should be poured into the groove. Wide seam plate, between the stainless steel pendant and the bottom of the stone has been installed with polymer polymer pad.
