Description of the Related Art Conventionally, in a reinforced concrete apartment house such as a condominium or a corpus, shocks and vibrations caused by falling objects or moving furniture on the upper floor propagate to the lower floor and become noise. Various sound insulation measures have been taken to improve the comfort on the floor.

を形成している。[0003] As a conventional sound insulation measure, for example, a floor plate base material is provided between the floor of a building and the floor of the building at the upper end of a rod-shaped support member having hard rubber or the like attached to the lower end thereof. A piping space is provided and fixed, and a heat insulating sound absorbing member such as urethane foam is provided so as to cover the floor of the building in the piping space, and a decorative floorboard is spread over the upper surface of the floorboard base material to form a floor structure. I have.
