1. Check whether the main materials, finished products and semi-finished products used in the project meet the design requirements, and do not use any defective materials.

2. Do not use wooden materials and other materials that do not meet the requirements of cleanliness standards in the clean room.

3, all kinds of materials in a closed, clean and dry environment, and flat on the moistureproof film.

4, the choice of color steel plate and aluminum profile, first of all, field visits to manufacturers, screening.

5. The color steel plate is made of Baosteel coil with the thickness of 0 and 5mm, with the second paint film. The color code is even milky white with no obvious color difference.

6. All the yin and yang angles of the partition wall in the clean area are connected by arc aluminum alloy pieces, and a special arc skirting line is adopted between the partition wall and the ground, with an arc radius of R=50.

7. The surface of the color steel plate is crisp, the bending is straight, the template size is error-free, and the whole bulging and depression of the color steel foamed plate are not allowed.

8. All doors are stainless steel hand locks, and the lock core is more than 65mm away from the door edge, except for the lock core with a key that can lead to the door lock outside the clean area.

Second, the construction conditions

1. The installation of color steel plate in clean area shall be carried out after the completion of civil engineering and decoration works, and the indoor space shall be clean and dust-free.

2. The requirements for ground flatness are high, and individual uneven places on the site should be reported to the owner, which will be handled by the ground construction unit.

3. After the completion of the pipeline and air duct construction in the ceiling, the construction of color steel plate shall be carried out after pressure test and concealed acceptance.

Third, the construction steps and scheme:

1. Setting-out: First, determine the vertical and horizontal reference lines according to the drawings, and check the dimensions of civil structures, if they are inconsistent with the drawings. Determine the position, distance and specifications of each door and window according to the drawings, and mark the opening direction of the door. The size deviation of each single room is not more than 2‰. The horizontal pipe shall determine the elevation of each axis, and indicate the elevation on the column at the same time to ensure the accuracy of determination. After the lofting is completed, please ask Party A, the supervisor and the designer to confirm, and the construction of color steel plate can only be carried out after confirmation.

2. Installation of geosyncline: The aluminum base plate must be close to the ground, and the error with the pay-off shall not be less than15 mm ... The aluminum seat shall be rounded with double corners. At the interval between l- 1 and 2m, the base is fixed on the ground in the middle of the seat with steel nails, and the error is corrected with gaskets. Ensure the length and size of joints at T-shape and corner, so as to facilitate the installation of three-dimensional corner pieces.

3. Installation of coaming and roof panel: The coaming and roof panel should be installed smoothly and tightly, and the gap width should be controlled at 3mm to ensure the quality of subsequent gluing. The corners shall be vertically connected, and the vertical deviation of the coaming shall not be more than 2‰.
