Blogs Raised access floors for office spaces

A raised floor (access floor or raised floor) is a raised access floor created above a solid floor slab usually made of reinforced concrete, leaving a gap between the two. This vacuum can be used to dispense technical fluids, such as:
Cabling for data and telecoms.
Electric power distribution.
Water supply and drainage.
Heating, Ventilating and Air Conditioning
Wiring for environmental controls, fire detection and extinguishing or security
Technical office floor layout
Raised floors appeared in the 1960s and have become more common with the increasing demand for technology in buildings. They are often found in offices or in areas with high demand for information and communication infrastructure such as data centers.
The raised access floor system provides layout flexibility for construction services and, with the inclusion of removable floor tiles, allows quick and easy access for reconfiguration and maintenance. It also allows spaces to be reconfigured or rearranged with as little disturbance as possible to ground distribution boxes, furniture or repositioning partitions.
Typically, the components of raised access floors used in office buildings include:
Adjustable feet, providing an adjustable vertical support structure for the raised floor. These can be tied to the basement and adjusted to provide a level plan.
Reinforcement bars, which can be used to connect the pedestals together, creating a frame for the floor panels and providing lateral stability, especially for deep void constructions.
Floor tiles, creating the flat surface of the raised floor.
Flooring, often carpet tiles that can be lifted to provide access to the plenum.
Floor boxes included in the floor tiles allow data services to penetrate through the floor and provide connection points for power, data, telecommunications, etc.
Raised floors can be gravity or bulk systems in which the floor panels rest on the head of the adjustable foot, providing easy access to voids under the floor, or to raised or screwed floors in which the floor panels are set on. the adjustable foot head for added safety.
Typically, office raised floor tiles are 600mm x 600mm. They can be formed from a chipboard core, covered with steel or can be laminated with finishes such as wood or stone. Ground voids can be as little as 20mm deep, and typically no more than 1200mm, although custom systems can achieve greater depths.
Raised floors can create sound bridges allowing sound to pass from office to office under partitions. Floor coverings and sound barriers can be used to reduce sound transmission, and joints between panels can be minimized or sealed.
Partitions can also be made through to the concrete slab, although this will reduce future flexibility. In general, flanking is more likely in ceiling voids because ceiling tiles tend to have less mass than floor panels.
When floor voids are used as plenums (that is, they are used as air ducts or can be extracted from a space for ventilation), it may be necessary to adjust the joints between the floor panels to avoid pressure loss.
