PURPOSE:To prevent dust from floating in the air by a method wherein floor panels equipped with gaps between the panels are placed in forming a space above a ground floor and upper finishing material with bored through holes are put on the panels. CONSTITUTION:A large number of through holes 4 are bored in the base part 2 of a tile carpet 1. Gaps are formed between the carpets and floor panels 5 on which carpets 1 are spread all over. A large number of floor panels 5 which form a space as an air passage 25 on a ground floor F through support legs 9, 10 are laid. A gap as a ventilation groove 12 is formed between the sides of adjacent panels 5 opposing each other. Conditioned air is sucked into a floor structure through the holes 4 and passes through the gaps between the carpets 1 and the panels 5 and flows into the grooves 12 and then the passage 25. The air passing through the passage 25 is sucked in an air blower. Thus, it does not occur that fine dust swirls up in the air. Further, a phenomenon that the air is sucked locally does not take place. |
