To provide a cavity for laying wiring and communication cables, as well
as for air conditioning to office premises, computer centres, telephone exchanges.
The structure for supporting the floor panels consists of hot-dip zinc-coated tubular steel supports which are located in floor plates and are fitted on the head or support plate (cross-connectior) with a threaded lecelling device permitting a tolerance of ± 30 mm. According to load requirements, the supports are bolted to the C-profiles to form a suitably dimensioned modular system on which floor panels of suitable size are placed. The joint is electrically conductive in accordance with VDE. For inspection or retrofitment, the floor panels and, if necessary, the modular system can be wholly or partly disassembled and reassembled.
