Raised floor - a type of raised floor used in production rooms in which it is necessary to separate engineering networks with access to separate equipment / installations / devices specially placed in this room.
For example, in computer centers, these are communications from a large number of cables for data transmission and power supply, as well as pipelines (for example, air conditioning or cooling systems) [1] [2] .
In some cases, the floor rises to a level sufficient to allow a person to crawl and even walk under it; To maintain the underground space, additional reinforcing elements are installed and lighting is carried out.

Design
Most often, the floor structure is formed from a supporting metal frame and removable panels, also made of metal, steel or aluminum. Depending on the application, various panel coatings are used: carpet, laminate, marble, stone, antistatic.
The vertical element of the system forming the frame, the rack , in the lower part has a support platform, whose design allows you to quickly change the height.
The horizontal frame element, a beam in the form of a bar from a steel profile, at the ends has a design for a fastener element , which allows connecting adjacent cells into a lock or using a bolted connection.
The mounted plate is usually in the form of a square, with sides 600 to 600 mm; less commonly used is a hexagonal shape . Special shock-absorbing pads are placed under the plate, which do not allow dust and contribute to sound insulation.
The raised floor construction system includes optional elements made in the same style: borders, inclined blocks , nodes for accommodating various sockets and connections , reinforcing ribs for areas of the floor with increased load. Special elements (for example, cable channel for wires and cables) allow to frame pipes, ventilation system outlets, load-bearing elements of building structures ( columns , pylons , etc.).
