【考案の詳細な説明】
（産業上の利用分野）
本考案は床下地材や床パネルの裏打ち材として
使用して床面上で発生する衝撃力を吸収、緩和
し、床衝撃音が階下へ伝播するのを軽減する床下
地用緩衝材に関するものである。[Detailed description of the invention] (Industrial application field) This invention is used as a floor underlayment material or a lining material for floor panels to absorb and alleviate the impact force generated on the floor surface, allowing floor impact noise to be transmitted downstairs. This relates to a cushioning material for floor subfloors that reduces the spread of the disease.
（従来技術とその問題点）
従来から、床面に対する衝撃力がコンクリート
床スラブ等の構造体に伝わつて階下に衝撃音とし
て放出することが問題となつており、この床への
衝撃音を軽減するために、床下地材としてグラス
ウールマツトやロツクウールマツト等の繊維質材
料からなる衝撃材がその衝撃音の吸収が良好な点
から広く使用されている。(Prior art and its problems) Conventionally, it has been a problem that the impact force on the floor is transmitted to structures such as concrete floor slabs and emitted as impact noise downstairs. For this purpose, impact materials made of fibrous materials such as glass wool pine and rock wool pine are widely used as flooring materials because of their good ability to absorb impact noise.
しあしながら、このような繊維質マツトよりな

べて変形しやすいために、コンクリート床スラブ
の凹凸表面を吸収して下地にもなじみ易いという
利点を有する反面、次に列記するような問題点を
有する。 However, since impact materials made of fibrous pine are more easily deformed than elastic boards such as foamed plastic boards, they do not have the advantage of absorbing the uneven surface of concrete floor slabs and easily conforming to the base. However, it also has the following problems.
(a) 吸湿や吸水によつて復元力が低下し易い。(a) Restoration power tends to decrease due to moisture absorption and water absorption.
(b) 圧縮変形と復元との繰り返しによつて衝撃材
内部に層間剥離が生じ、復元力が低下する。(b) Due to repeated compression deformation and restoration, delamination occurs inside the impact material and the restoring force decreases.
(c) 局部圧縮による変形が大きいために、その上
面に根太材等を載置した場合、局部的に凹みが
生じる。(c) Because the deformation due to local compression is large, if a joist or the like is placed on the top surface, a local dent will occur.

な繊維マツト単独であるので、床衝撃力が作用す
ると、局部的に大きな圧縮変形を生じて衝撃力が
床下地に集中して作用するという欠点があり、床
衝撃力の吸収性が充分でなかつた。 On the other hand, in order to prevent fibrous pine such as glass wool pine from absorbing moisture and deteriorating its insulation properties and resilience due to water absorption, it has been proposed to cover the outer surface of fibrous pine with a film of rubber or synthetic resin. ,
Although it is partially used for flooring materials, etc., if it is simply made of fibrous pine covered with waterproof coating, it is impossible to eliminate the occurrence of dents due to local compression, and it is stable when directly supported by joists or floorboards. Since it is made of fiber mat alone, it lacks flexibility and is flexible, so when a floor impact force is applied, a large compressive deformation occurs locally, and the impact force is concentrated on the subfloor. I wasn't sexual enough.

ができても、床下地全体に敷き詰めるような床下
地材としての用途には不適当である。 In addition, in order to reduce the compression deformation of fibrous pine, fibrous pine that increases the density of the fibrous pine and takes compression resistance into consideration is also used, but with this structure, the flexibility is reduced. Lowering and unevenness of the base,
It cannot absorb unevenness, etc., and when it is laid over the entire surface of a concrete floor slab as a subfloor material, unevenness will occur on the surface.It is used for the same purpose as earthquake-proof rubber placed between floor joists and support metal fittings. Even if it is possible to do so, it is unsuitable for use as a flooring material that is spread over the entire flooring.
さらに、防水皮膜が損傷して繊維質マツト内に
湿気が入ると、放湿することができずに湿気が溜
る一方となつて復元力が低下してしまうという問
題点を有する。 Furthermore, if the waterproof coating is damaged and moisture enters the fibrous mat, there is a problem in that the moisture cannot be released and the moisture accumulates, reducing the restoring force.
本考案はこのような問題点を解消した床下地用
緩衝材の提供を目的とするものである。 The object of the present invention is to provide a cushioning material for flooring that solves these problems.

特徴とするものである。(Means for Solving the Problems) In order to achieve the above object, the cushioning material for flooring of the present invention has the following features as shown in the drawings corresponding to practical examples:
A pressure plate 2 is laminated on the top surface of a fibrous cushioning material 1 such as glass wool mat, and a waterproof elastic coating 3 is applied from the bottom surface of the fibrous cushioning material 1 to the side end surfaces of the fibrous cushioning material 1 and the pressure plate 2. It is characterized by being coated.

る。(Function) When the pressure plate 2 laminated on the fibrous cushioning material 1 is used to support floor materials, joists, etc., the load is evenly distributed over the entire surface of the fibrous cushioning material 1 on the lower layer side, and the fibers are compressed locally. In addition to eliminating distortion in the fiber cushioning material 1, the floor impact force is uniformly distributed and transmitted throughout the fiber cushioning material 1, reducing the amplitude of the floor surface caused by the impact force and reducing floor impact noise. When laid on a floor slab, the fibrous cushioning material 1 absorbs irregularities on the surface of the concrete floor slab.

くするものである。 In addition, the waterproof elastic coating 3 covering from the bottom surface of the fibrous cushioning material 1 to the side end surfaces of the fibrous cushioning material 1 and the pressure plate 2 can be applied to a concrete floor without impairing the flexibility of the fibrous cushioning material 1. It prevents moisture from the slab from penetrating into the fibrous cushioning material 1, and also prevents the alkali components of the concrete from affecting the fibrous cushioning material 1. Furthermore, the waterproof elastic material covers up to the side edges. The coating 3 prevents delamination of the fibrous cushioning material 1 due to repeated compressive deformation.

機繊維を使用してもよい。 The fibrous cushioning material 1 is made of fibrous pine such as glass wool pine or rock wool pine, and is made of a relatively low-density fibrous material so as to be able to absorb the uneven surface (unevenness) of the subfloor such as a concrete floor slab. Ru. For example, in the case of glass wool, the density is 48-96Kg/ m2 , and in the case of rock wool, the density is 100Kg/m2.
A density of ~150Kg/ m2 is optimal. Also,
As the fibrous cushioning material 1, organic fibers formed into a felt shape may be used in addition to the glass wool and rock wool mat described above.

いものである。 A pressure plate 2 is laminated on top of this fibrous cushioning material 1.
The material is not specified as long as it is a plate-shaped body with higher rigidity than the fibrous cushioning material 1, but it is preferably made of a material such as plywood, particle board, slate board, wood fiberboard, or foamed plastic board.
In particular, if a wood fiberboard with excellent moisture absorption and desorption properties is used as the fibrous cushioning material 1, the waterproof elastic coating 3 may be damaged or broken and the fibrous cushioning material 1 may be partially exposed. Even if water or moisture infiltrates into the fibrous cushioning material 1, it will not remain inside the fibrous cushioning material 1, but will be immediately released to the outside due to the moisture absorbing and desorbing properties of the wood fiberboard, and the restoring force will be improved. It never deteriorates.

るものである。 The waterproof elastic coating 3 that covers from the lower surface of the fibrous cushioning material 1 to the upper end of the side end surface of the pressure plate 2 includes:
For example, foamed rubber, foamed synthetic resin, soft synthetic resin sheets, etc. are used, and the fibrous cushioning material 1 and the pressure plate 2 may be adhered with a suitable adhesive, but as shown in FIGS. As shown in FIG. 6, an unfoamed rubber sheet or synthetic resin sheet 3a is placed on a lower mold 5 via a release film 4, and a fibrous cushioning material 1 and a pressure plate 2 are sequentially placed on this sheet 3a. After lamination, the sheet 3a may be closed with an upper mold 6, softened and foamed by heating, and fused from the lower surface of the fibrous cushioning material 1 to the upper end of the side end surface of the pressure plate 2. In this case, when the sheet 3a softens, it also fits into the cavity at the side end of the fibrous cushioning material 1 and is bonded together, thereby preventing delamination at the side end of the fibrous cushioning material 1.

増大させることができるものである。 Further, the thickness of the waterproof elastic coating 3 may be uniform over the entire surface, but is thinner on the lower surface of the fibrous cushioning material 1 and the thickness of the fibrous cushioning material 1 and the pressure plate 2.
It is preferable to make the side end faces thicker. When formed in this manner, the thinner lower surface side is easily deformed and can better absorb the uneven surface of the concrete floor slab, while the thicker end surface portion can increase delamination resistance.

部の歪みを小さくすることができて好ましい。 Furthermore, if the lower end corners of the waterproof elastic coating 3, which are the connecting parts between the four peripheries of the lower surface and the lower ends of the side end faces, are made thicker than the side end faces, the restoring force of the side end faces is increased. This is preferable because distortion of the side end surface portion due to compressive distortion can be reduced.

伝わる振動が小さく且つ短くなるものである。(Effects of the invention) As described above, according to the cushioning material for flooring of the present invention, the pressure plate 2 is laminated on the upper surface of the fibrous cushioning material 1 such as glass wool mat, and the pressure plate 2 is stacked on the upper surface of the fibrous cushioning material 1 such as glass wool mat. Since the fibrous cushioning material 1 and the pressure plate 2 are coated with a waterproof elastic coating 3 over the side end surfaces thereof, the fibrous cushioning material 1
Since the pressure plate 2 is placed on top, when supporting floor materials, joists, etc., the load is evenly distributed over the entire surface of the fibrous cushioning material 1 on the lower layer side, and the fibrous cushioning material 1 is compressed locally. It is possible to eliminate distortion, and in addition, the uneven surface of the base such as a concrete floor slab can be absorbed by the fibrous cushioning material 1, making it possible to perform construction with high precision. Therefore, since it acts on the fibrous cushioning material 1 in a uniformly distributed manner, vibrations on the floor surface can be quickly absorbed by deforming the entire fibrous cushioning material 1, and
When the floor vibrates, the pressure plate 2 generates a natural vibration on the fibrous cushioning material 1 in addition to the vibration of the floor, and the natural vibration of the pressure plate 2 absorbs some of the vibration energy of the floor. As a result, the vibrations transmitted to the subfloor become smaller and shorter.

とができるものである。 Furthermore, since the waterproof elastic coating 3 is coated from the bottom surface of the fibrous cushioning material 1 to the side end surfaces of the fibrous cushioning material 1 and the pressure plate 2, the flexibility of the fibrous cushioning material 1 is not impaired. Something that can prevent moisture from a concrete floor slab from entering the fibrous buffer material 1, thereby eliminating a decrease in restoring force, and also preventing the alkaline components of concrete from affecting the fibrous buffer material 1. In addition, the waterproof elastic coating 3 covering the side end faces eliminates delamination of the fibrous cushioning material 1 due to repeated compression deformation and delamination from the pressure plate 2, and always exerts a stable restoring force. It is possible to achieve a uniform buffering effect, and when it is installed, it is possible to eliminate friction between adjacent pressure plates 2, 2, thereby eliminating the generation of squeaking noises and the like.

とができるものである。 In addition, by making the side end surface part of the waterproof elastic coating 3 thicker than the bottom surface part, the restoring force of the peripheral edge part of the cushioning material is improved, and sinking due to compressive strain of the peripheral edge part is prevented. In addition, the thin lower surface portion conforms well to the unevenness of the base and can absorb unevenness.
さらに、耐圧板２として吸放湿性の良好な木質
繊維板を使用すれば、万一、防水性弾性被膜３が

でき、復元力の低下を防止できるものである。 Furthermore, if a wood fiberboard with good moisture absorption and desorption properties is used as the pressure plate 2, even if the waterproof elastic coating 3 is damaged, the pressure plate 2 will absorb moisture that has entered the fibrous cushioning material 1. This allows for smooth discharge to the outside and prevents a decrease in restoring force.
