    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).
