Cleanroom sandwich panel installation company shares Cleanroom sandwich panel installation process and requirements

Regarding the installation process and requirements of  sandwich panel, the installation company of  sandwich panel is introduced as follows:

1. The Cleanroom sandwich panel installation company introduced to be familiar with the drawings, carefully reviewed the sandwich panel layout, node requirements, the connection between the sandwich panel and the building, the color, filler and basic size requirements of the sandwich panel itself, the size and layout of doors and windows in the sandwich panel partition, the type of auxiliary materials and other unknown contents.

2. Secondary layout drawing, which is an important step in the prefabrication and installation of sandwich panels, is to convert the design drawings into the second processing that can be used in the factory, to make the standard specification plates into different types of wall plates, to combine the intermediate conversion drawings to reflect the design intent, and to produce standard plates in the sandwich panel factory and assemble them on the construction site, which can ensure the firmness of the wall plates and speed up the installation.

3. When prefabrication in the factory, according to experience, the gap and installation allowance are fully considered between door openings, window openings and joints. And in the whole process of transportation, production, installation, to prevent scratches, heavy pressure and surface impact, to prevent the appearance of uncorrectable pits and scratches. The plastic protective films on both sides of the sandwich panel are allowed to be removed only after the installation is completed and thoroughly cleaned.

4. The pay-off work before the installation of the sandwich panel shall be carried out after the ground (floor) surface is completed, and can only be carried out when other relevant conditions for installation are met, such as the larger equipment has been transported in place, the hidden ground pipeline has been adjusted and the main installation work of the technical interlayer has been basically completed. The pay-off is to draw the horizontal projection (50mm wide) of the sandwich panel and the position of the door and window on the ground. The center line of the upper and lower manger should be within 1.0% or 3mm on the same vertical plane.

5. The Cleanroom sandwich panel installation company told everyone to install the upper and lower manger. The lower manger generally adopts aluminum alloy profiles with internal and external R angles. Fix the nail on the line drawn on the ground with a straight line of 1.2-1.5m spacing, and the corner and terminal are 0.2m away from the side. For those with water-stop rubber strips, put two rubber strips (Ф 2-3) under the groove before nail shooting, and form waterproof isolation and sealing after nail shooting.

The upper manger is pressed 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 layer with a boom. The height is subject to the clear height of the ceiling.

6. Thin vertical wall panels, install prefabricated components according to the layout, and lock adjacent wall panels with fixed inserts between components. It is worth paying special attention to the combination of electrical concealed pipelines and boxes while assembling the wall panels.

The wall plate should be vertical and the vertical seam should be tight. The smaller the gap, the more beautiful it is, and the vertical seam should be uniform.

The Cleanroom sandwich panel installation company introduced that during operation, carefully clean up the protective film on the vertical seam and temporarily uncover it, and never uncover it.

Clean up the sundries in the tank and solidified hard blocks with bonded glue. Otherwise, it is difficult to adjust the vertical seam evenly and tightly with even force.

7. Installation of hanging top plate: The weight support of the top plate is through the vertical plate fixed at the periphery and the T-shaped aluminum suspended in the middle. The long side seams are fixed and reinforced by fixed inserts, and the short side is fixed by T-shaped aluminum and connecting plate blind rivets.

The hanging flat top strives to be flat, and the plate seams are dense and uniform, smooth, seamless and harmless. Pay attention to the same vertical panel.

8. sandwich panel with column, box, yin and yang R angle

The columns in the purification area are wrapped with a sandwich panel of 50, which is beneficial to save materials and unify the yin and yang R angles of 50.

First, install stainless steel door and window frames at the door and window openings to fix them firmly. Pay attention to the opening direction of the door and install the window glass. The door closer should adjust the opening speed and strength. Generally, the first half of the door is fast, and the second half is small and slow to reduce the impact and noise of the door.

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

The Cleanroom sandwich panel installation company introduced the splicing joints between sandwich panels, all the gaps between R angle and wall plate and top plate;

The gap between air conditioning duct, tuyere, filter and wall top plate;

The gap between all switch socket lamps and the top surface of the sandwich panel;

All processes, water supply and drainage, protection pipe and clearance of the hole;

The gap between the glass and the frame;

Sealing silica gel should be installed on the color plate basically ready, sanitary conditions are good, after thorough cleaning and dust removal, unified. Otherwise, the silica gel seam is easy to pollute and blacken. Within 24 hours after the silica gel is beaten, there should be no large amount of dust operation and washing the ground with water, which may affect the curing and fastness of the sealing silica gel.
