Abstract
A sound insulating floor structure comprises an underlying floor layer of a raised floor constructed by supporting a plurality of underlying floor panels at a predetermined height by means of a group of supporting legs installed on a foundation floor via elastic pedestals attached to the lower ends of the supporting legs, floor covering materials laid over the underlying floor layer, and intermediate materials laid between the underlying floor layer and the floor covering materials. The intermediate material is a hardboard or a high density fiberboard having the flexural strength of 35-50 [N/mm], Young's modulus in flexure of 4,000-5,000 [N/mm] and the density of 0.8-1.2 [g/cm].
