Friends who want to decorate the ceiling decoration in the home, you can look at our gypsum board ceiling expansion joints, what is the gypsum board ceiling expansion joints, what are the characteristics of our gypsum board ceiling expansion joints, and still doing What are the construction steps of this gypsum board ceiling expansion joint and what are the precautions for the gypsum board ceiling expansion joints? Our friends can read the following article. First, the characteristics of gypsum board ceiling expansion joints 1. Construction expansion joints should be uniform Because the expansion joint layout of the ceiling must be more uniform and consistent, the design effect is more beautiful. In the past few years, the variety of suspended gypsum board has been increasing, and in the process of design, more owners will be recognized by this gypsum board, which shows the technical performance or processing technology is more prominent. The uniform decoration concept and layout are still more unique, showing more different places. 2, the construction of expansion joints must be exquisite In fact, in the process of making gypsum board ceiling expansion joints, it is necessary to highlight the exquisite craftsmanship effect, to achieve a unique aspect in the design, to understand the effect in the decoration process, the process is reflected in the process The more advanced. This is to make the whole gypsum board ceiling technology more prominent. In the gypsum board market sales process in the country, you feel that the technical performance parameters of each gypsum board will be more different, all in order to It is more comprehensive and reasonable in the process of indoor ceiling. Second, gypsum board ceiling expansion joint production 1. Conditions for making expansion joints: Expansion joints should be provided for the distance between the single side of the gypsum board ceiling and more than 12 meters. Double-layer gypsum board ceilings need to leave 10-20mm seams, the length of the joint is 30-50mm, and the distance between the edges of the expansion joints and the hanging ribs is not more than 300mm. The single-layer gypsum board ceiling is lined with a blockboard (fireproof treatment) connected to the side keel, and the lower mouth is left with a 10-20mm seam. The width of the wall exceeds 12m, the left and right sides of the wall panel and the three sides of the ceiling, and the four sides of the southeast and northwest of the ceiling are to be left with expansion joints. This joint should be treated with elastic sealing paste or decorative beading. 2, the method of making expansion joints: fix one side vertical keel, and nail one layer, two or three layers of 12mm (or 15mm) gypsum board on the vertical keel, and then install another back to back from 10mm Side vertical keel; along the position of the control expansion joint, leave a 12.5mm gap to install the gypsum board on both sides of the wall. 3. Cut a length of expansion joint fitting with the same length as the control joint. According to the different types of expansion joint fittings, use quick-drying glue or self-tapping screws to fix the expansion joint fittings at the expansion joint of the plasterboard; Seam processing; extract the rubber strip from the expansion joint fitting. Third, gypsum board ceiling expansion joints Note 1. Before the formal construction, the worker must first use the horizontal pipe to measure the level of the ink line of the wall bomb. Only the exact level of the basic line will not cause the later installed ceiling to tilt or have a high and low drop. 2, gypsum board ceiling needs to be fixed on the solid wooden keel frame, so the careful selection of the keel material has become an indispensable step, we try to choose the loose wood quality with better nail strength. 3. Because the keel is woody, it is necessary to pay attention to fire prevention. The standard practice is to evenly apply the fireproof coating on the surface of the keel, and the whole keel is white, and then nailed to the wall, which can also contact the wall. Brush to fire retardant coatings. 4. After the surface of the keel is fireproofed, the combination can be started. The worker will use a nail gun to fix the angle between the two keels at an angle of 45 degrees. At this time, it is necessary to master the strength to prevent cracks in the keel. 5. After the keel frame is nailed, the frame needs to be fixed to the wall. At this time, it is necessary to carefully check whether the spacing between the frames is not more than 300 mm to have sufficient fastness. Otherwise the plasterboard on it will easily sink and break. 6. The gap between the two gypsum boards must be handled in the next step, otherwise obvious cracks will occur in the future. The average worker will use 901 glue and gypsum powder to mix and fill. The above content is what are some of the characteristics of our gypsum board ceiling expansion joints, and how do we make this gypsum board ceiling expansion joints, and what are some of the precautions we have made in this gypsum board ceiling expansion joints, friends We learned about the expansion joint of this gypsum board ceiling, and continue to pay attention to our decoration home network to learn more about decoration.
