Abstract (en)
[origin: EP0459135A1] In order to achieve a maximum air penetration cross section with low-turbulence flow of the air through the false floor, in the case of false floors panels for ventilated clean rooms for example, the top panel 12 of the false floor panel is evenly perforated over virtually its entire surface. Additionally the supporting grid for the top panel 12 is made of similarly evenly perforated hollow profile bars 14a. The free edges of the hollow profile bars 14a are fixed to the top panel 12 at least primarily only at those zones at which it exhibits a full section between the perforations (slots 13). <IMAGE>
