1. Familiar with the clean room drawings, carefully review the color steel plate layout, node requirements, the relationship between color steel plate and building, color steel plate itself color, filler, basic size requirements, door and window size and layout in color steel plate partition, Types of auxiliary materials and other unknown content.

2. Secondary board drawing, this is an important step in the prefabrication and installation of color steel plates. It is to transform the design drawings into a second processing in the factory. The standard specification boards are made into different types of wall panels and combined to reflect the design intent. The intermediate conversion diagram of the color steel plate is produced, and the standard plates are produced in the color steel plate factory, and assembled at the construction site, which can ensure the firmness of the wall panels and speed up the installation speed of the color steel plates.

3. When prefabricating in a clean room factory, based on experience, fully consider the gap and installation allowance between door openings, window openings and seams. And during the entire transportation, production, and installation process, prevent scratches, heavy pressure and surface impact to prevent uncorrectable pits and scratches. The plastic protective film on both sides of the color steel plate is only allowed to be removed after the installation is completed and thorough cleaning is performed.

4. The laying-out work before the installation of the color steel plate in the clean room should be carried out after the ground (floor) surface is completed, and other relevant installation conditions such as larger equipment has been transported in place, the underground pipeline has been adjusted, and the main installation of the technical mezzanine The work is basically completed before it can proceed. Pay-off is to draw the horizontal projection of the color steel plate (50mm wide) and the position of the door and window on the ground. The center lines of the upper and lower mangers should be on the same vertical plane and the error should be within 1.0%, which is 3mm.

5. For the upper and lower mangers, the lower mangers are generally made of aluminum alloy profiles with inner and outer R angles. Use nails to fix on the line drawn on the ground. The position of the nails should be 1.2-1.5m in a straight line, and the corners and terminals should be 0.2m away from the side. If the water-stop rubber strip is used, put two rubber strips before shooting the nails ( Ф2-3) Put it under the slot and form a waterproof isolation seal after the nail is fixed.

The upper manger is made of pressed trough aluminum. When the ceiling is hard, it is fixed on the top plate with a nail gun. When the ceiling is soft, it is suspended under the floor by a boom. The height is subject to the ceiling height.

6. The thin vertical wall panels are assembled into the prefabricated components according to the layout drawing, and the adjacent wall panels are locked by fixed plug-ins between the components. It is worthy of special attention to fit the electric concealed pipelines and boxes while assembling the wall panels.

The siding should be vertical, and the vertical seams should be tight. The smaller the gap, the more beautiful it is, and the vertical seams are even.

During operation, carefully clean the protective film on the vertical seam and temporarily uncover it, but never remove it.

Clean up the sundries in the tank and the solidified hard blocks of the glued liquid. Otherwise, it will be difficult to adjust the vertical seam uniformly and densely with no amount of force.

7. Install the clean room ceiling board: the weight support of the ceiling board is through the vertical board fixed on the periphery and the T-shaped aluminum suspended in the middle. The long side seam is fixed and reinforced by fixed inserts, and the short side is fixed by T-shaped aluminum and connecting plate blind rivets.

The suspended flat roof strives to be flat, and the board seam is dense and uniform, smooth, without traces and injuries. Note the operation of the same standing siding.

8. Color steel plate clad column, bag box, yin and yang R angle

The pillars in the purification zone are separately wrapped with б=50 color steel plates to save materials and unify the Yin and Yang R angles are both 50.

First, install the stainless steel door and window frame into the door and window hole and fix it firmly, pay attention to the opening direction when installing the door, and install the window glass. The door closer should adjust the opening speed and power. Generally, when closing the door, the first half of the speed is fast, the second half of the torque is small, and the speed is slow, so as to reduce the impact and noise of closing the door.

9. Sealing silica gel: In the purification area, all the following gaps that may affect the cleanliness should be coated with sealing silica gel:

The splicing seams between the color steel plates, all the gaps between the R angle and the wall panels and the top panel;

The gaps between air-conditioning ducts, vents, high-efficiency filters and wall ceilings;

Electricity passes through the gap between the protective pipe groove on the top plate of the wall panel and the edge of the hole;

The gap between all switch socket lamps and the top surface of the color steel plate;

Clearance between all crafts, water supply and drainage, protection pipes and openings;

The gap between the glass and the frame;

The sealing silica gel should be installed on the color plate basically, and the sanitary conditions are good. After thorough cleaning and dust removal, the clean room is carried out in a unified manner. Otherwise, the silicone seam is easy to be polluted and blackened. Within 24 hours after the silica gel is finished, there should not be a lot of dust and water washing the ground, which may affect the curing and fastness of the sealing silica gel.
