BACKGROUND ART Conventionally, flooring materials for medium-to-high-rise residential buildings have generally been carpets or the like directly attached to concrete floors through felt. However, carpets tend to get dirty easily, require a lot of effort to replace, and are prone to dust mites.
そこで、カーペツト類を貼る代わりに木質系床
材をコンクリート床に直接貼付けるという手段を
用いることが多くなつてきた。 Therefore, instead of pasting carpets, a method of directly pasting wood-based flooring materials onto concrete floors has become more common.
ところが、木質系床材はカーペツト類に比べ遮

床材上に与えられた衝撃音が該木質系床材を伝わ
つて階上から階下に伝播して階下に響くために、
居住性を損なうという欠点があつた。 However, since wood flooring has poor sound insulation properties compared to carpets, for example, when wood flooring is directly attached to the floor of an upper floor, the impact noise applied to the wood flooring is is transmitted from the upper floor to the lower floor through the wood flooring material, and is echoed downstairs.
It had the disadvantage of impairing livability.
このような欠点が解決するためには、木質板の
裏面全体に合成樹脂発泡体を貼着すれば多少改善
されるが、それでも十分ではなかつた。 In order to solve these drawbacks, some improvement can be achieved by attaching a synthetic resin foam to the entire back surface of the wooden board, but this is still not sufficient.
本考案は上述した如き事情に鑑み、遮音性のす

In the figure, 1 is a wooden board, and on the back side of this wooden board 1 are a perforated cushioning sheet 2 made of a foam material with many through holes formed therein, a perforated wooden board 3, and a cushioning material 4. They are pasted together in sequence. In addition,
In the present invention, a part is composed of the above-mentioned wooden board 1, a perforated cushioning sheet 2 made of a foam material pasted on the back side of the wooden board, and a perforated wooden board 3 pasted on the back side of the cushioning sheet. For convenience, it is called "decorative plywood."

要である。木質板１の厚さは2.5〜3.3mmが好まし
いが、これに限定されるものではない。 Examples of the wood board 1 include plywood, particle board, hardboard, parallel plywood, etc., and the surface thereof is decorated as appropriate. This decoration is done, for example, by pasting a veneer of precious wood or a patterned synthetic resin sheet on the surface or by painting it. Note that this invention may also be used as a flooring material, but in this case no makeup is required. The thickness of the wooden board 1 is preferably 2.5 to 3.3 mm, but is not limited to this.
木質板の裏面に貼り合わせる有孔緩衝性シート
２としてはゴム発泡体やオレフイン系発泡体等の
緩衝性のあるシートに多数の貫通孔を設けたもの
であればよく、孔の直径は３〜20mm、厚さは１〜
２mmが好ましい。 The perforated cushioning sheet 2 to be attached to the back side of the wooden board may be a sheet with cushioning properties such as rubber foam or olefin foam with a large number of through holes, and the diameter of the holes should be 3 to 3. 20mm, thickness 1~
2 mm is preferred.

mmのものが好ましい。 As the perforated wood board 3 for the intermediate layer, plywood, parallel plywood, hardboard, particle board, etc. with a plurality of through holes can be used, and the thickness is 2.5 to 4.0.
mm is preferable.
緩衝材４としては、ポリオレフイン系発泡体、

い点で好ましい。 As the cushioning material 4, polyolefin foam,
Rubber foam or the like is used, and among these, closed foam is preferred because it has excellent waterproof properties and is less prone to collapse than open foam.
本考案による床材においては、前記のように中
間層として、多数の貫通孔を設けた発泡材料から
なる有孔緩衝性シート２、及び多数の貫通孔を穿
設した有孔木質板３とを用いたことにより、特有
の効果を奏する。 In the flooring material according to the present invention, as described above, the perforated cushioning sheet 2 made of a foam material with many through holes and the perforated wooden board 3 with many through holes are used as the intermediate layer. By using it, it has a unique effect.
すなわち、孔を形成することにより機械的強度
を不必要に低下することなく空隙率の大き有孔緩
衝性シート２及び有孔木質板３を得ることがで
き、それらを、衝撃音の発生部位である上層の木

とから、各層を形成する部材間での有効接触面積
を大きく低減することが可能となり、有孔緩衝性
シート２及び有孔木質板３自体を介しての上方か
ら下方への音の伝達面積を大きく低減することが
できる。 That is, by forming the holes, it is possible to obtain the perforated cushioning sheet 2 and the perforated wooden board 3 with large porosity without unnecessarily lowering the mechanical strength. Since it is placed as an intermediate layer between the wood board 1 on the upper layer and the cushioning material 4 on the bottom layer, which is the part where the impact sound propagates downstairs, the effective contact area between the members forming each layer is increased. This makes it possible to greatly reduce the transmission area of sound from above to below through the perforated cushioning sheet 2 and the perforated wooden board 3 themselves.
中間に位置するシートや木質板に空隙を形成す
る他の方法としてそれらの幅方向に多数の切り溝
を形成する方法もあるが、切り溝を形成すること
は全幅方向に連続した空隙を形成することとな
り、結果として、シートや木質板の機械的強度の
低下を引き起こす。それにより、木質系床材の床
面への施工時に該切り溝部分において屈曲（いわ
ゆる「へたり」）が発生する可能性が高くなる。 Another way to create voids in sheets or wooden boards located in the middle is to form a large number of kerfs in the width direction, but forming kerfs creates a continuous void in the entire width direction. This results in a decrease in the mechanical strength of the sheet or wooden board. As a result, there is a high possibility that bending (so-called "settling") will occur in the cut groove portion when the wood flooring material is installed on the floor surface.
そのような屈曲により、表面材としての木質板
に歪みが生じ、その歪み部分は、床材の表面に光
を照射したときにあたかも切り溝の形状に沿つた
陰影であるかのような見えてしまうことから、そ
の床材自体が不良品であるとして再施工せざるを
得ないこととなる。 Such bending causes distortion in the wooden board used as the surface material, and when light is irradiated onto the surface of the flooring material, the distorted part appears as if it were a shadow following the shape of the groove. As a result, the flooring material itself must be considered defective and have to be reinstalled.
その不都合は、中間層としての緩衝性シートや
木質板に多数の貫通孔を形成することにより大幅

複数の切り溝の場合と同容積の空隙を複数の貫通

れにより、「へたり」の発生する確率は大きく低
減し、施工時に不良品が発生するのを回避するこ
とが可能となる。さらには、切り溝では達成でき
ない程度の大きな空隙を形成することも可能とな
る。 This inconvenience can be largely eliminated by forming a large number of through holes in the buffer sheet or wooden board as the intermediate layer. In other words, since the voids formed by the plurality of through holes are discontinuous,
When a plurality of through holes form a void having the same volume as a plurality of kerfs, the effect of the void on the mechanical strength of the cushioning sheet or wooden board is small. As a result, the probability of "sagging" occurring is greatly reduced, making it possible to avoid producing defective products during construction. Furthermore, it is also possible to form a large gap that cannot be achieved by cutting grooves.
さらに、緩衝性シートの材料としてゴム発泡体
やオレフイン系発泡体等の発泡材料を用いること
により、繊維質材料の場合のように接着剤により
材料が硬化しそれにより緩衝性が低下するのを阻
止することができる。 Furthermore, by using foamed materials such as rubber foam or olefin foam as the material for the cushioning sheet, it is possible to prevent the material from hardening with adhesives and reducing its cushioning properties, which is the case with fibrous materials. can do.
また、緩衝材４として、裏面にジユート織布を

は、直径10mm、高さ１〜２mm程度が好ましく、形
状は円形、楕円形、方形等何でもよい。 Further, as the cushioning material 4, a rubber foam with a juute woven fabric pasted on the back side can also be used. In this case, the juute woven fabric is attached to the bottom surface of the flooring material. In addition, if the cushioning material is made of a material that can have protrusions, providing the protrusions on the back side of the cushioning material will further increase sound insulation as the contact area between the flooring material and the concrete surface will be reduced by the protrusions. We can expect that. The projections provided on the back surface of the cushioning material preferably have a diameter of about 10 mm and a height of about 1 to 2 mm, and may have any shape such as circular, oval, or rectangular.

に向上することが期待される。 In addition, the upper layer wooden board 1 and the middle layer perforated wooden board 3
It is possible to optionally perform a sag process to remove sag over the entire area, that is, around the decorative plywood part, to suppress the movement of the surface layer plywood. At that time, the decorative plywood may be divided into smaller pieces than a single sheet (1 shaku x 3 shaku) and joined so that a groove is formed at the joint as shown in Figure 2. In that case, The grooves can also block sound propagation paths, and are expected to further improve sound insulation.
