What Is A Raised Access Floor?

Raised access floors are a type of floor used in modern buildings with advanced equipment that provides cables, wiring, power, air conditioning, and cooling water pipes. In addition, the floor is raised high enough for people to crawl or walk underneath and often needs to provide structural support and lighting.

Performance characteristics of raised access floors

1. High mechanical strength, strong bearing capacity, good impact resistance;

2. Surface electrostatic spraying, soft light, wear resistance, waterproof, fireproof, dustproof, corrosion-resistant;

3. The pasted decorative high-pressure layer has excellent wear resistance and anti-static performance, anti-pollution, easy to clean, and strong decorative properties;

4. High dimensional accuracy, good interchangeability, flexible assembly, convenient maintenance, and long service life;

5. The floor can be cut arbitrarily and accessories can be installed conveniently;

6. The four sides are fixed and easy to install;

7. The lower space can be used for air conditioning and ventilation, and the ventilation volume of the bottom layer can also be adjusted with the ventilation plate;

8. For overweight equipment, as long as a bracket is added under the floor, the bearing problem can be solved;

9. Easy to disassemble and assemble, as long as the decorative veneer is replaced, it can be reused;

10. When installing the ground socket, the hole can be opened according to the specifications of the ground socket. Scope of application: All-steel floors are suitable for occasions with high load requirements and anti-static requirements, such as main computer rooms with large servers and cabinets; large, medium and small computer rooms, communication center rooms represented by switches, various electrical control rooms, postal and telecommunications hubs, and military, economic, national security, aviation, aerospace and traffic command and dispatch and information management centers controlled by computers.

Site environment requirements:

optimal temperature 10-30℃, relative humidity RH30-70%,

Temperature change rate:

ΔT≤15℃/hour

Vibration:

no frequent vibration (source)

Chemical environment:

no highly corrosive volatile substances

Advantages of raised access floors

1. Cable Management: Raised floors provide an excellent solution for managing cables, wiring, and other utilities, making it easier to organize and access them.

2. Cooling Efficiency: They improve air circulation and cooling efficiency in data centers and office spaces, as air can be directed under the floor.

3. Flexibility: Raised floors offer flexibility for future modifications and expansions, as it is easier to add or move cables and other components.

4. Aesthetics: They help maintain a clean and uncluttered appearance by hiding cables and ducts beneath the floor.

5. Accessibility: Easy access to underfloor systems for maintenance and repairs without disrupting the workspace above.

Disadvantages of raised access floors

1. Cost: Installation and maintenance of raised floors can be expensive compared to traditional flooring solutions.

2. Height Limitations: They reduce the available height in rooms, which can be a limitation in spaces with low ceilings.

3. Structural Issues: Raised floors can add extra weight to the building structure and may require additional support.

4. Complex Installation: The installation process can be complex and time-consuming, requiring skilled labor.

5. Moisture and Dust: The space under raised floors can accumulate moisture and dust, potentially leading to maintenance issues and affecting indoor air quality.

Construction process of raised access floors

1 Clean the ground where the elevated floor is to be installed, and the ground must be flat and dry. It should be a ground that has been leveled with cement mortar, and the height difference should be less than 4 mm measured with a 2-meter level ruler

2. Draw lines on the cleaned ground to determine the position of each bracket.

3 Install the bracket at the fixed position, install the frame and adjust the height of the entire bracket.

4 Assemble the bracket beams and adjust the beam level at the same time. It is recommended to use a laser level, then tighten the screws and fix the beams.

5 Install the raised floor and trim the raised floor at the same time.

6 Install the skirting after the floor is installed to protect and beautify the wall.

7. Clean the floor surface after construction.

Precautions of raised access floors

1. It is forbidden to rinse the surface of the raised floor with water. It should be cleaned with a wrung mop.

2. Do not lay gas pipes or water pipes under the floor.

3. Do not use hard objects or sharp objects to squeeze, impact, and scratch the finish and plastic coating.

4. Do not use overweight items.
