A ventilated floor comprises a distance member 4 which rests on a subfloor 1 and forms air ducts 6 in association with the subfloor 1. Mounted on the distance member 4 is a load-absorbing layer 7 with a floor covering 8. According to the invention, the floor is, along one edge, connected to a hollow profile 10 which is sealed against an adjacent wall 13 and against the upper side of the floor and which is connected to the ducts 6 via openings 9; 26. The profile 10 is connected to a fan. Along another edge portion of the floor 7, the ducts 6 are flow- connected to the surroundings via a filter 21, and, along the other edge portions, the floor is sealed against adjacent walls. In one embodiment, the profile 10 has a leg 23 which extends across the floor and seals against the latter by means of a rolling or sliding seal 24. <IMAGE> |
