A final top floor covering is laid on top of a top floor portion formed of fiberboard panels which in turn are disposed on top of smaller square fiberboard elements forming a bottom floor portion. The square fiberboard elements in turn are laid on top of resiliently elastic panels which form a supporting floor. The edge length of the fiberboard panels is an integral multiple of the edge length of the individual square fiberboard elements, which latter is preferably smaller than the edge length of the elastic panels of the supporting floor, wherein the joints between the various panels and elements forming the supporting floor, bottom floor portion, and top floor portion are not in mutual alignment. In a modified form the top floor portion, bottom floor portion and supporting floor are constructed in prefabricated floor elements with overlapping marginal zones whereby adjacent prefabricated floor elements are connected together by screws or the like. |
