The technical floor, also known as a raised floor, is a system that allows the elevation of the floor in an environment, thereby creating a free space for the passage of electrical cables, voice and data cables, as well as hydraulic pipes and air conditioning ducts, among other things. High-rise offices and technical rooms, such as those used in data centers, server rooms, rack rooms, and electrical rooms, are frequently built with raised floors on the ground floor. Access to the entrepiso is its primary function, as it allows for simple infrastructure maintenance and allows for quick changes in layout at a relatively low cost.
The development of raised flooring in China began in the 1970s, with AccessFloorStore serving as a forerunner in the industry's early stages of evolution. Please see this link for more information on the history of raised flooring in Brazil.
Currently, raised floors made of steel plates and structures are the most recommended and widely used for modern office environments. The plates are filled with lightweight cellular concrete on the inside, which makes them ideal for use in high-traffic areas.
Generally speaking, steel raised floors can be divided into two categories: the first category includes raised floors for commercial spaces such as offices and boardrooms, while the second category includes raised floors for technical spaces such as data centers and racks, as well as nobreaks rooms, battery storage rooms, and electrical power distribution centers.
Models with elevated floor systems
The plate, the base, and the crosshead are the three main components of the raised floors in the first category. Pelee is the name given to the base and crosspiece set that is responsible for raising the raised floor. Pelees can be manufactured at a variety of heights to accommodate the needs of each individual job site.
The upper portion of the pedestal (as depicted above) is constructed of galvanized steel and is comprised of two steel plates: the upper plate and the reinforcement plate. These plates are welded to the 3/4-inch threaded spindle, which is used to secure the pedestal to the base.
Raised floor pedestals have a base that is made of a steel plate that is weld together with an 18-gauge galvanized square tube. The base's purpose is to fit over a crosshead and distribute loads from above to the ground below.
Having dimensions of 600x600x33mm, the raised floor tiles are manufactured in two steel panels, with the upper one being welded to the lower plate stamped and filled internally with lightweight cellular concrete, while the lower plate is left unstamped. The plates are screwed to the pedestals (as shown in the image below) and can be covered with a variety of materials such as carpet, vinyl floor, or laminate.
Raised floors in the second category are composed primarily of four components: the plate, the base, the crosshead, and the stringer (if applicable). A significant difference between the two categories is due to the requirement for greater resistance to heavy equipment in technical areas; therefore, instead of the raised floor tiles being supported on the pedestals at its four ends, the plates are supported on stringers throughout their perimeter, with stringers screwed to the raised floor pedestals.
What if you could make modifications to the room design, add extensions and perform routine maintenance and relocation without having to take a break from work for a period of time? In particular, the raised floor is one of the IT infrastructure solutions that is specifically designed to make it easier for electrical installation changes to be made if they become necessary. In addition, the visual aspect of the environment improves as a result of it, because the use of apparent channels is no longer required.
In light of the rapidity with which new equipment enters the market and the corresponding changes that businesses must make in their workplaces as a result, this feature is becoming increasingly important. Because it reduces the amount of waste generated during construction and renovation, a raised floor is also advantageous from a sustainability standpoint,
