Elastic line, installation of boom, installation of main keel, installation of auxiliary keel, arching and leveling, installation of aluminum gusset 1. According to the drawings, firstly pop the ceiling level ink line on the wall and column, draw the ceiling layout on the top board, determine the position of the boom and weld with the original reserved boom, if the original hanging rib position does not match or there is no reserved rib At the time, the M8 expansion bolt is fixed on the top plate, and the boom is processed by φ8 steel bar. 2. Install the large keel according to the ceiling elevation. After the basic positioning, adjust the hanging and flattening the lower skin (note the amount of arching); then determine the position of the middle and small keels according to the specifications of the plate. The middle and small keels must be close to the bottom of the big keel. Apply clamp clamps when installing vertical suspension to prevent tightness. 3, the main keel spacing is generally 1000mm, the keel joints should be staggered; the direction of the boom should also be staggered to avoid tilting the main keel to one side. Use the bolts on the boom to adjust up and down to ensure a certain degree of arching. Depending on the size of the room, the arch is 5-20mm, and the room is short to 1/200. After the level is adjusted, tighten the nut one by one. The opening position requires the big keel. Reinforcement. 4. Pay attention to the cooperation between the various types of work during the construction process. After the construction of the tuyere, lamps and fire-fighting pipelines in the ceiling is completed, the panels can be installed after various tests. 5, aluminum plate installation: pay attention to the surface color of the aluminum plate, must meet the design specifications, the geometrical dimensions of the aluminum plate is verified, the deviation is ± 1mm, pay attention to the size of the seam when installing, gently remove the surface protective film after installation. First, the main control project 1. The elevation, size, arching and styling of the ceiling should meet the design requirements. 2, the material, variety, specifications, patterns and colors of the facing materials should meet the design requirements. 3. The installation of the boom, keel and facing materials of the dark keel ceiling project must be firm. 4. The material, specifications, installation spacing and connection method of the boom and keel should meet the design requirements. Metal hangers and keels shall be treated with surface anti-corrosion treatment ; wooden hangers and keels shall be treated with anti-corrosion and fire prevention. Second, the general project 1. The surface of the facing material should be clean and uniform in color, and there should be no warpage, cracks or defects. The bead should be straight, wide and narrow. 2. The position of the lamps, smoke detectors, sprinklers, tuyere and other equipment on the veneer should be reasonable and beautiful, and the intersection with the veneer should be consistent and strict. 3. The joints of metal hangers and keels should be uniform and uniform, the corner joints should be consistent, the surface should be flat, and there is no warping or hammering. The wooden boom and keel should be straight and free from splitting and deformation. 4. The variety and thickness of the sound-absorbing materials filled in the ceiling should meet the design requirements and should have anti-scatter measures. 5. The allowable deviation and inspection method for the installation of the dark keel top project shall comply with the provisions of Table 6.2.21 of the “Construction Quality Acceptance Code for Building Decoration Engineering†: Surface flatness: 2mm. Seam straightness: 1.5mm. Seam height difference: 1mm.
