とされている。[Prior art] Generally, noise transmitted from the upper floor through the floor is JIS-
As described in A-1418, it is roughly classified into a light impact sound and a heavy impact sound. The method of preventing these impact sounds is basically different. That is, since the light impact sound generated by the hard impact body is in the high frequency range, the floor structure is required to have a high frequency absorption capacity, and is usually used for carpet,
It is said that it is effective to use a soft finishing material such as a tatami mat. The heavy impact sound generated by the soft impact body is in a low frequency region, and the floor structure is required to have a low frequency absorption capacity. In general, a method of increasing the mass of the floor structure is regarded as an effective means.

For this reason, the wet floating floor structure is not widely used at present, although it has excellent floor impact sound insulation performance.

であればよい。The present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of one embodiment, in which a three-dimensional plastic fiber net (2) is placed on the upper surface of a floor slab (1), and a mortar reinforced with a reinforcing wire mesh (3) is cast as a hydraulic composition. It is the structure which did. The plastic fiber three-dimensional network (2) used is one in which a waterproof sheet is attached to at least the upper surface of the three-dimensional network to prevent cement mortar from entering the net. Also, as shown in FIG. 2, a waterproof sheet (5)
Can be placed on the three-dimensional net, separately from the plastic fiber three-dimensional net (2). Further, as shown in FIG. 3, a plastic fiber three-dimensional net (2) may be laminated in two layers. In addition, the floating floor structure according to the present invention is not limited to these structural examples, and any structure may be used as long as at least a plastic fiber three-dimensional mesh is used as a buffer layer.

100N/cm2・cmを超えると衝撃音の緩和効果は充分でなく
なるからである。As the three-dimensional net used in the present invention, a non-resonant, forced vibration type dynamic stiffness tester is used in a three-dimensional net made by entangled synthetic resin filaments that have fluttered relatively rigidly. It is preferable to use a structure that exhibits a value of 100 N / cm 2 · cm or less at room temperature. The lower the value, the better. This value is
If it exceeds 100 N / cm 2 · cm, the effect of reducing the impact sound is not sufficient.

Filaments such as low-density polyethylene / vinyl acetate copolymer, ABS resin, and rubber-modified polystyrene are insufficient in "stiffness", and therefore include only a three-dimensional net formed in a partial range.

ような挙動を示さない材料が多い。These three-dimensional nets are formed into a coarse mat shape by interlacing filaments as described above, have a large porosity, have appropriate elasticity, have a large effect of absorbing vibration energy, and have a concrete slab. It also has the effect of absorbing the undulations (unevenness). Although the thickness of the filament varies depending on the material, a filament having a diameter of 0.2 to 3 mm is usually used in order for the reticulated body to have a physical property value of 100 N / cm 2 · cm or less.
If the diameter is smaller than this, no matter how dense the net-like structure is, it will be deformed by a load or an impact and the soundproof effect cannot be exhibited.
If the thickness is 3 mm or more, there are many materials that are too rigid and do not exhibit a behavior to reduce the impact sound.

などによりクラックを生じる恐れもある。Concrete, lightweight concrete, mortar, and the like are used as the hydraulic composition used for the floating floor layer, and a gypsum-based self-leveling material is generally used as a finish. The thickness of the floating floor layer is preferably 30 mm or more, and the greater the thickness, the greater the effect of blocking the impact sound. When the thickness is less than 30 mm, the effect of blocking floor impact noise is not sufficiently exhibited, and cracks may occur due to a load or the like.
