Two Main Methods To Install Raised Floor (Technical Floor) - Raised Access Floor Installation Techniques

Raised floor is also known as technical floor or access floor, has been widely used in industrial and commercial places. In our previous article, we have introduced that raised floors can be divided into two categories according to application and functionality: traditional raised floor systems and low-profile raised floors. And two different technical floor installation methods have been derived on basic of these two types of access floors. In today's article we will introduce you two raised floor installation techniques.

Raised Floor (Technical Floor) Installation Techniques

There are two methods of laying the raised access floor:

In self-supporting assembly, mostly for installing a low profile raised floor in offices:

• - Up to 500 mm in height and running load;

• - Only the jacks support the panels and allow easier access to the vacuum under the floor.

In assembly with reinforcing cross members, mostly for installing the traditional raised floor in data centers:

• - The stringers and pedestals allow the ground to be raised beyond 500 mm while supporting heavy concentrated loads.

• - The rigidity of the computer cabinet installation platform is reinforced.

Self-supporting Raised Access Floor Installation Steps

Self-supporting mounting is chosen when the finished heights are less than or equal to 500 mm. In the type of self-supporting raised access floor construction, the slabs must rest directly on the cylinder heads. There is therefore no installation of access floor stringers.

The installation steps will be as follows:

• 1) Installation of the jacks. These jacks are fixed to the ground:

  - With a special "anti-vibration" glue;

  - By screwing;

  - Or by welding if they are resting on structural irons.

• 2)The earthing braid is fixed:

  - Using a collar;

  - Or by pinching in a notch provided for this purpose.

• 3) Installation of raised floor panels.

Steps for Installing Raised Access Floor With Stringer Supporting

The installation of the raised access floor on a transom is chosen:

• For heights of raised floors above 500 mm.

• For raised floors not wedged at the periphery.

• For raised floors requiring a lot of cutting.

It is thus necessary to provide for the placement of cross members for the braced assembly. This leads to:

• Improved horizontal stability of the floor;

• Improved resistance to load.

The installation steps will be as follows:

• Installation of stringers.

• Placement of solid raised floor panels on the stringers.

• Installation of "T" slabs to define squareness.

• Cutouts and installation of edge slabs to block the entire assembly before being able to walk on the floor.
