.: Modular raised floors

Modular raised floors can be used anywhere there is a need to run wiring and services inside rooms with access to workstations - especially if direct access to the sub-floor cavity is required across the entie floor area.

The floor is made of 60x60 cm modular panels, supported on pedestals - either directly at the corners or using a frame structure.

In both cases the pedestals are permanently mounted on the slab in the 60 x 60 cm modular grid.

The sub-floor cavity (with a height ranging to 60 cm without a supporting frame and up to 200 cm with a supporting frame) can be used to run all types of services: electrical, telephone, computer, industrial TV, alarm, water, heating, air conditioning etc.)

Panels can be equipped with openings where one can install cassettes for various outlet types, such as power, telephone or computer.

    .: Support structure















    Depending on the floor height and load size and type, various types of support structures are used.

    1. Free-standing pedestals.

    Steel pedestals, zinc- and chromium-coated, are mounted on the slab surface using a special glue, forming a standard 600 x 600 mm grid. In exceptional cases the pedestals are additionally fastened with pins.

    Pedestals consist of two parts which make it possible to adjust the height of the panel support.

    Floor height range: 70 to 600 mm.

    Pedestal heads are covered with conductive polyethylene covers which dampen vibrations and ensure equal distribution of the panel load on the pedestal head.

    This is the basic and most frequently used support structure type.

    2. Pedestals linked by bracing rods

    Bracing rods are made of zinc-coated steel as 30 x 30 x1.5 x 537 mm closed-profile shape or 30 x 30 x 1 x 537 mm open-profile shape. The ends of the rods have openings for connections with screws to pedestal heads. Bracing rods increase the stability of the support structure.

    Floor height range: 400 to 1200 mm or less if horizontal loads are present.

    3. Pedestal-mounted support frame.

    Support frame beams are made of 2 mm zinc-coated steel as 40 or 60 mm wide profiles with height of 40, 65, 80, 100 or 105 mm. Trade length - 6 m. They are placed on pedestal heads and fastened by screws. Pedestal heads have a special shape and openings that make frame mounting easier. Floor panels rest on the support frame with two or four edges.

    This panel support system significantly increases the system safe load and stability.

    Floor height range: 150 to 2000 mm.

    If additional work has to be done in the sub-floor cavity, it is possible to remove all floor panels without making the support structure unstable.

    Thanks to these advantages, the support structure can be used in low and high voltage switching stations, telephone exchanges and in any rooms where there are dynamic loads, especially horizontal (moving lifts, trucks).

    In low and high voltage switching stations the grid of load-bearing beams can be adjusted to fit the dimensions of switching station cubicles, incorporating them into the cubicle's load bearing frame. Space underneath cubicles can freed for installation access and cabling.

    The upper level of load bearing frames on which cubicles are mounted is flush with the surface of floor panels.

    .: Floor finish types:

    Floor surfaces can be finished using all generally available of flooring materials, such as:

  • flexible plastic floor lining: linoleum, PVC, rubber
  • carpeting
  • natural and artificial stone
  • ceramic tiles
  • wooden parquet
  • metal, glass
  • special-purpose floor lining

    Prior to application all floor lining materials are tested by trial application and subjected to resistance tests.




    .: Raised floors on metal frame:














    Raised floors mounted on metal frames are most often used in:

  • low and high voltage switching stations;

  • surfaces intended for motor vehicle traffic,

  • telecommunication exchanges,

  • structures exposed to the risk of tectonic movements or to shocks or explosions,

  • in industrial areas.

    Pedestal-mounted support frame.

    Support frame beams are made of 2 mm thick zinc-coated steel as 40 or 60 mm wide profiles with a height of 40, 65, 80, 100 or 105 mm.

    They are placed on pedestal heads and fastened with screws. Pedestal heads have a special shape and openings that make frame mounting easier.

    Floor panels rest with three or four edges on the support frame, via pads which dampen striking sounds.

    This panel support system significantly increases the system safe load, compared to the system where panels rest directly on pedestals, and considerably increases the system stability.

    Floor height range: 150 to 2000 mm.

    If additional work has to be done in the sub-floor cavity, it is possible to remove all floor panels without making the support structure unstable.

    Low and high voltage switching stations

    In low and high voltage switching stations the grid of load-bearing beams can be adjusted to fit the dimension of switching station cubicles, incorporating them into the cubicle's load bearing frame. Space underneath cubicles can be freed for installation access and cabling.

    Such a solution allows high loads to be applied in switching station cubicles, and also allow unlimited access to the cubicles from underneath.

    The upper level of load bearing frames on which cubicles are mounted is flush with the surface of floor panels.

    Surfaces intended for motor vehicle traffic

    If modular raised floors are to be used in warehouses and production facilities such as printing shops they need to be adapted to provide the possibility for the use of forklift and palette trucks. This will result in dynamic loads, including horizontal loads, which can be safely and failure-free transferred to the concrete slab via the metal frame and pedestals.

    Telecommunication exchanges and other telecommunication facilities.

    Telecommunication operators expect high standards with regard to easy access to the sub-floor cavity in any rooms where they keep their telecommunication equipment - due to the large quantity of cabling. Another very important issue is the need to provide efficient ventilation of telecommunication equipment which can be best ensured by running ventilation ducts underneath the raised floor.

    Structures exposed to the risk of tectonic movements or to shocks or explosions.

    Floor panels are attached to the frame structure using screws and special pads which can absorb large quantities of strike energy, therefore considerably increasing panel resistance to damage. In this case the support frame will transfer contraction as well as expansion loads (important in the case of shocks).

    This type of floor has been tested by the German Civil Defence and approved for use in shelters.





    .: Caring for floor surface:








    General precautions

    While cleaning the floor, use as little water as possible, because it may leak through gaps between panels or around installation openings and reach the services underneath, causing malfunction of some equipment. In the case of chipboard panels, water could also cause swelling of the panels. This is why the floor must in no case be cleaned with water.

    In rooms to which antistatic protection requirements apply one has to pay attention that surface care products used do not contain any substances that may create an insulating layer (wax, resin) which would hamper the outflow of static electric loads.

    In order to avoid the need for thorough floor cleaning using water, it is advised that maintenance cleaning should be carried out with increased frequency.

    Apart from the above guidelines, we recommend that manufacturer recommendations concerning the cleaning of and the care for various types of floor lining should be followed.

    Below please find general recommendations concerning the leaning of and care for carpeting, PVC and linoleum floors.

    Carpeting:

    - maintenance care: remove dust by vacuum-cleaning using a standard nozzle or special carpet-beating attachment;

    - thorough cleaning: remove dust by vacuum cleaning using a special carpet-beating attachment, then clean using carpeting cleaning powder (moist cleaning), after drying vacuum-clean again using the carpet-beating attachment.

    PVC and linoleum floors:

    Regular cleaning and care has an impact not only on the appeance and sanitary conditions in the rooms, but also on the floor durability.

    Prior to its first use, the floor lining has to be protected by a special formulation, otherwise later cleaning will be difficult and result in higher costs.

    1.  Cleaning after completion of construction work

    Remove all dirt. Under normal circumstances generally available cleaning agents added to water used to clean the floor will suffice. (See: the comment at the start of this section concerning water usage).

    2.  Preliminary care.

    This will be done directly after the cleaning as described above, prior to first use of the floor. The task of the protective layer is to protect PVC floor lining against mechanical and chemical damage, improve its appearance and make cleaning easier. We recommend emulsions that are to be applied undiluted. In places which are more susceptible to staining/soiling or where higher hygiene or appearance standards apply, it is recommended that the protective emulsion be applied twice.

    3.  Periodical (regular) maintenance cleaning

    This is a regular cleaning regimen to be applied over an extended period of time. It is recommended that a damp cloth be used and water with added cleaning agents whose type and quantity will depend on the degree and type of soiling. For larger floor areas special mechanical cleaning equipment is often used.

    4.  Thorough cleaning.

    Thorough cleaning will be required from time to time, for example if periodical maintenance cleaning does not give the desired result. In the process both dirt and the protective layer are being removed. After the floor lining surface has dried, apply the protective layer again, as described under point 2.




    .: Installation cassettes:

    Installation cassettes and power outlets are a necessary feature of a raised floor and provide a way to plug any electrical or telecommunication devices into the existing cabling without problems.

    Openings for the installation of installation cassettes can be made in floor panels. We recommend the use of floor cassettes in which one can install power, telephone and computer outlet boxes with 45 module, most often used in cabling inside buildings. Cassettes and boxes may come from various suppliers. For example we recommend well-known brands such as Legrand or ACKERMANN.

    Floor cassettes may be round or rectangular and can hold between one and eight outlet boxes. Three to four 45 module sockets can be installed in each outlet box.

    Cassettes are equipped with covers to which one can apply the same surface lining as laid over the entire raised floor surface (if carpeting, PVC or linoleum is used). The cover has one or two small openings for cables, covered with their own small covers. Therefore, even if there are cables running out of the cassette, the cassette itself remains flush with the floor surface, which will ensure appropriate functionality and appearance.



    .: Ventilated raised floor:










    Ventilation panels are used as air inlets in ventilation systems, providing individual air distribution through placing an appropriate number of ventilation panels with selected capacity in appropriate locations on the floor.

    Ventilation panels can vary in number, size and shape of ventilation openings and, therefore, can supply air streams of varying size.

    Ventilation panel with "threaded" opening

    Openings with gradually changing diameters are drilled through panels. The complete set includes a waste intercept basket and a gland. There can be between one and four ventilation openings per panel. With more than three openings, it is necessary to use a reinforcing frame.

    Capacity: 35 - 50 m3/h per each opening.

    Ventilation panel with round openings

    Openings with gradually changing diameters are drilled through panels. The complete set includes a waste intercept basket and a gland. There can be between one and four ventilation openings per panel. With more than three openings, it is necessary to use a reinforcing frame.

    Capacity: 80 - 100 m3/h per each opening

    Steel ventilation panel

    Over 1000 single openings with diameter of 8, 10 or 12.5 mm grouped in seven rows, supplied along with metal gland or a regulator of the number of openings open. Surface of opening cross-section: about 17%, 26.4% or 38%. Capacity: over 1000 m3/h.

    This large ventilation capacity makes it especially suitable for engine rooms.

    Ventilation panel with openings in rows Openings are diagonally drilled through panels in three rows. Surface of opening cross-section: 107 cm2. Capacity: 150 - 180 m3/h




    .: Electrostatic qualities:

    Raised floors made of mineral panels (paroll 90, paroll 90b) as well as those made of cardboard paroll 140b panels and finished with antistatic floor lining can be used in rooms where protection requirements against static electricity, fire protection and interference have to be complied with, such as workstations for assembly and operation of electronic testing and control equipment, diagnostic equipment, telecommunication and computer equipment, including explosion-risk zones Z0, Z1, Z2 and Z10.
