Raised ventilation flooring structure

Abstract

The invention relates to a raised ventilation flooring structure ( 105,106 ) comprising a first and a second transverse support beam ( 107,108 ) extending substantially parallel in a transverse direction T at a predetermined mutual distance W. The support beams ( 107, 108 ) are interconnected via connection profiles ( 109, 110 ) to form a grid structure. Carrier profiles with side walls having a number of apertures, are supported with their ends on the support beams ( 107, 108 ). A panel with a closed surface is supported on each carrier profile with side edges of adjacent panels being spaced apart to form a ventilation gap ( 55 ). The support beams ( 107, 108 ) form elongate collection members that extends along and/or below the side walls of the carrier profiles in the length direction L, below the ventilation gap, to form collection channels ( 70,100 ). An air flow path extends from a space between the side walls of the carrier profiles ( 50,51 ), via the apertures ( 42,44 ) to the collection channel ( 70,100 ) and to the ventilation gap ( 55 ) between the adjacent panels ( 46,48 ).
