The design must comply with requirements of fire protection, antistatic, dustproof, soundproofing, etc.
2.2.2. Ze design planml
When building main environment of command center, access floor is a very important part. The raised floor is laid in construction site of computer room, and computer equipment and other electronic equipment is installed in raised floor, and various pipelines connecting equipment can be laid in space between raised floor and construction site. The entrance is detachable, so it is very convenient to connect wires and cables of all equipment, pipeline connection and maintenance and replacement, and laying route distance is shortest, which reduces signal loss during infection transmission.
In addition, raised floor can be quickly installed and dismantled, which makes it easier to place and configure equipment, and also creates favorable conditions for expansion and replacement of equipment.
The floor height of computer room of this project is 0.3 m. An all-metal wear-resistant and anti-static floor is used. The surface of floor is glued with conductive PVC veneer, floor is powder coated. - resistant paint.
