Abstract
A floating floor comprises a plurality of square buffer members arranged in parallel at regular intervals on a supporting structural floor, a plurality of floor panels vertically spaced above the supporting structural floor by the supporting members to form an air layer between them. The floor panels are respectively provided with a plurality of air holes through which the air layer is communicated with the outside of the floor panels. The floor panel may be a hollow panel having a plurality of cavities extending in parallel in the longitudinal direction of the panel and being opened at butt ends of the panel, each cavity being communicted with the air layer through said air holes to form passages from the air layer to the outside of the floor panel. Instead of square buffer members, there may be used square supporting members and a buffer layer so that the floor panels are vertically spaced above the buffer layer by square supporting members to form an air layer between them.
