Glass mosaic ceiling construction method:
Material requirements:
According to the requirements of the tender and the selection of materials determined by the owner, design and supervision, the materials used are high-quality brand products, and the acceptance is strictly in accordance with national norms and standards. Keel: U-shaped light steel keel and keel fittings (main keel is UC38); mold-proof and moisture-proof paper gypsum board: 2400×1200×12 (length×width×thickness) mm; boom and angle steel: Ф8 steel bar as a boom. Angle steel: L40 × 4 length 40mm.
Process flow:
Measuring take-up line→Boom processing and on-site fixing→Installing main keel→Main keel leveling→Fixed medium and small keel→Concealed acceptance→Moldproof and moisture-proof paper gypsum board installation→Nail cap treatment→Slotting→Elasting grid line→Paste mosaic → pointing conservation <br> <br> construction operation points:
Measuring the pay-off line: according to the design elevation of the drawing, the elevation line is popped around the wall, the hanging point and the keel position line are popped up on the bottom surface of the floor, and the position line such as the light trough and the tuyere is ejected to avoid sawing the keel, requiring the line to be clear and accurate. . Boom processing and on-site fixed processing: Calculate the length of the boom according to the ceiling of the drawing, and process it in the processing factory. One end is ferrule-wired, the other end is welded with small angle steel of L40×4 (length 40mm), and the small angle steel is pre-staged with bench drill. Snoring the hole of 12. Use Ф8 steel bar to make the boom after welding and brush the anti-rust paint twice. On-site installation and fixing: the principle of the distance between the booms is generally not more than 1200mm. According to the on-site pay-off, the electric hammer is used for punching, and then the M10 expansion bolts are used to connect with the boom. The distance between the boom and the end of the main keel shall not exceed 300 mm, otherwise a boom shall be added. Install the main keel and leveling: the keel installation sequence, first the main keel, then the second keel. Connect the keel hanger to the boom, tighten the screws and secure. The horizontal length of the main keel is lengthened by the connecting piece. After the main keel is installed, immediately adjust the room height as the unit, and the height of the ceiling of the large-span room ceiling is not less than 1/200 of the short span of the room. The small and medium keel is fixed with the hanging keel and the big keel. The spacing is generally 400mm, and the lower surface of the small and medium keels are at the same level.
Keel reinforcement: For the shape ceiling in the height of the ceiling, the main keel should be reinforced, and the ends should be welded and fixed to each other. For spot welding of light steel big keel, small and medium keels cannot be welded. Concealed acceptance: Before sealing the board, after the completion of the professional pipeline construction such as lighting, ventilation, fire sprinkler and smoke sensation in the ceiling, the installation and construction of the gypsum board can be carried out after being qualified by the owner, the supervisor and the construction unit. Anti-mold and moisture-proof gypsum board installation: first place the plate in place, drill the gypsum board and keel with electric drill, and then tighten with self-tapping screws. The sinking depth of the self-tapping screws is slightly buried into the surface of the nail cap and Without breaking the paper surface, the distance between the self-tapping screws is 150-170mm, the distance between the peripheral screws and the edge of the plate is 10-15mm, and the distance from the cutting edge is 15-20mm.
When the gypsum board is installed, the board layout design and the staggered arrangement are installed according to the parts or the room. The gap of the plate is 8-10mm. When laying, the long side of the gypsum board is laid in the direction of the longitudinal secondary keel. After the plates are installed, apply anti-rust paint to all the nail caps and smooth them with plaster putty. Gypsum board surface caulking: When installing gypsum board according to requirements, 8-10mm gap should be reserved at the joint. The special caulking putty powder is added with latex, and then mixed with a proper amount of sawdust to form a paste, and a caulking material is prepared. First clean the floating dust in the slats. The caulking should be carried out in three times. The depth of each embedding is about 4mm. Wait until the putty is filled and then fill it again. It must be filled all over and over the base. Squeeze tightly. According to the size of the mosaic, the vertical and horizontal grid lines are played.
Apply a high-strength adhesive to the back of the mosaic, paste the mosaic on the gypsum board according to the cross line, and press it with a wooden trowel. After 24 hours, use the Smith's board type mosaic grout to sew and use the corresponding diameter of the steel wire to lubricate. Wipe with cotton yarn.
Quality Standard:
The variety and color of the materials should meet the design requirements, and it is strictly forbidden to crack. The mosaic seams are uniform and uniform, straight and straight, and there must be no obvious misalignment or staggering. The environmental protection measures are not removed from the adhesive. During operation, the insulation layer on the ground is cleaned up in time after construction.
Safety and civilized construction requirements:
Construction personnel must abide by the relevant safety production laws and regulations as well as the provisions for safe construction.
Construction personnel must wear a safety helmet and wear a badge (passing pass) when entering the construction site.
It is strictly forbidden to smoke at the construction site. It is strictly forbidden to urinate and urinate. It is strictly forbidden to chase and play. On-site equipment and electrical appliances should be managed by a dedicated person.
