Description of the Related Art Conventionally, as a floor-mounting structure of this kind, as shown in FIG. 8, a supporting leg 1 having an adjustable level and having an elastic body 2 at a lower end is attached to four corners of a panel body 3, and these panel bodies 3 are concreted. What is mounted on a floor base 4 such as a slab is well known. The disposing material 5 is stuck on the panel body 3 on the floor base thus configured. Then, a finishing material (not shown) is attached on the waste material 5 to form a floor. Therefore, this type of floor-standing structure has a large underfloor space. In addition, a so-called direct-attached floor in which a sound-absorbing material is directly placed under the floor without a supporting leg and having a low floor height has been used.

When the height of the supporting leg 1 is reduced in the floor placing structure of the related art shown in FIG. 1, when a shock is applied to the panel body 3, a large sound is generated from the panel body 3 into the underfloor space, and the sound pressure in the underfloor space increases, The elastic body 2 is deformed by the impact and the panel body 3 bends downward, so that the tendency of air movement (horizontal movement) immediately below the point of impact becomes conspicuous, and the sound absorbing performance is reduced. Also,
On the directly pasted floor, although the floor height could be lowered, the floor elasticity was too low and the walking feeling was poor.
