Clean room ceiling grid system based on the characteristics of clean room design with simple processing, easy assembly and disassembly, and easy routine maintenance work after the completion of the clean room. The modular design of the ceiling system, plasticity, can be factory production, but also the scene cut, greatly reducing the process of construction pollution, and high strength of the system, you can walk on, especially for high clean area, such as electronics, semiconductor, medical industry. Ceiling keel system components: 1.T-bar:. 1) T-shaped structure, dry ceiling, anodized aluminum material, surface electrophoresis 2) T-bar cross joints can be installed sprinklers, smoke detectors and lights wire 3) T-bar can be installed under clean room teardrop lights 2. connection: 1) connector includes cross connectors, T-joints, corner joints, zinc alloy material, the entire system is connected by a threaded fastener as a whole . 2) full-wire boom galvanized with adjustable height adjuster ceiling, connected by a clip and nut 3) nuts and screws are galvanized material 3. The system scalability: You can easily install efficient filters, FFU, etc. . Clean room ceiling keel construction 1. Baseline check - check the reference level line - boom pre - install loft boom - boom installation - ceiling keel pre - installed ceiling keel - ceiling keel leveling - the ceiling joists Positioning - Cross reinforcement piece installation - Measuring Marginal keel size - Interface income side - the ceiling joists gland installation - ceiling keel leveling 2, check the baseline a serious familiar with the drawings, confirmed the construction area and cross the baseline position based on relevant information. b. Use theodolites and laser level meter to check the ceiling baseline. 3, check the reference level line a. Determined according to the ground elevation of smallpox or raised floor. 4, pre-boom a. According storey, calculate the length of each ceiling height needed to boom, and then cutting. b. When working to meet the requirements of the boom and square and then the pre-set regulators and other accessories. 5, the boom installation: After staking boom installation, start large-scale boom boom based on the location of the installation, slip through the flange nut to the airtight ceiling keel. 6, when the ceiling joists prefabricated prefabricated keel, can not peel off the protective film, the hexagonal screws need tightening, moderate area can be pre-set. 7, ceiling keel installation prefabricated ceiling joists on the boom lifting overall good pre-set on T-type screws, square regulator offset cross joint center 150mm, the T-type screws and flange slip nut. 8, after the ceiling joists leveling a construction area when the keel to keel horizontal adjustment, making adjustments with a laser level, and a receiver, the level should not exceed the ceiling elevation difference 2mm, shall not be lower than the ceiling level. 9, when the keel ceiling keel positioning after installing certain region, the need for a temporary position, with the correct weight and the center of the ceiling cross baseline deviation shall be within the range of one millimeter. Alternatively steel pillars and walls or civil positioning points. http://www.zzhyjh.com decontamination, purification color plate, clean air-conditioning, clean room clean, ventilation ducts
