In the ceiling project of buried parts, reinforcing steel rod and shape steel rod should carry on antirust or anticorrosion treatment; when the ceiling upper part as static pressure box, buried parts and the floor or wall of the articulation place, should carry on sealing treatment. Support hanger should take dustproof processing.
4. The fixed and hanging parts of the ceiling, should be connected with the main structure. Shall not be connected with equipment bracket and pipeline bracket; ceiling hangings shall also not be used as pipeline hanger or equipment hanger.
5. Air filters, lamps, smoke detectors, loudspeakers and all kinds of pipeline through the ceiling at the hole around the hole should be flat, tight, clean, and blocked with non-combustible materials. The perimeter of the maintenance opening of the concealed project should be sealed with sealing gasket.
6. The ceiling elevation, size, arch, plate gap should comply with the design requirements. The gap between the board should be consistent, each gap between the board error shall not be greater than 0.5mm; and with sealant evenly sealed, do flat, smooth, slightly below the board, shall not have a break and impurities.
7. The material of the ceiling finish, varieties, specifications, etc., should comply with the design requirements, and the product performance for verification.
8. The spacing between the hanging rods should be bigger than 1.5m. The distance between the hanging rods and the main keel end should not be bigger than 300mm.
9. The installation of the boom, keel and decorative panel must be safe and firm.
