Description
【０００１】0001
本考案は、マンション等の防音床材に関し、特に 250 Hz 以下の低周波音を効 的に制振する木質系防音床材に関するものである。 This invention relates to soundproof flooring materials for condominiums, etc., and is particularly effective against low-frequency sounds below 250 Hz. This article relates to a wood-based soundproof flooring material that effectively damps vibrations.
【０００２】0002
ホテルやマンションでは、特に上階の部屋での人に歩行や子供の跳びはね音、 椅子を移動させる時に発生する個体音等騒音が居住性の悪化を招く大きな要因と なっている。上記騒音の原因はすべてが振動であり、人が歩行したり、跳びはね る時の振動がコンクリートスラブに伝達されて発生するものであり、これらの音 の振動波が伝わらないように従来からカーペットや絨毯を敷くなどの種々な工夫 がなされている。 In hotels and condominiums, the noise of people walking and children jumping, especially in rooms on the upper floors, can be audible. Noise such as individual sounds generated when moving chairs is a major cause of deterioration of livability. It has become. All of the above noises are caused by vibrations, such as people walking or jumping. These sounds are generated when vibrations are transmitted to the concrete slab. Conventionally, various methods such as laying carpets or rugs have been used to prevent the vibration waves from being transmitted. is being done.
【０００３】 一方近年においてはカーペットや絨毯に代えて木質床材が好まれ、そのため階 下への衝撃音の伝達がより顕著となっている。このことを考慮して建築時におい て床下部分に木製または鋼製の根太を用い、その上に床材を張る工法が実施され ているが、この程度では上階の音を十分遮音することはできない。0003 On the other hand, in recent years, wooden flooring has become preferred in place of carpets and rugs, and as a result, floor The transmission of impact sound downwards is more pronounced. This should be taken into consideration during construction. A construction method has been implemented in which wooden or steel joists are used at the bottom of the floor, and flooring material is placed on top of the wooden or steel joists. However, this level is not sufficient to block out the sound from the floors above.
【０００４】 この木質床材上で発生する音の伝達を弱めるべく、例えば実開昭63-119740 号 公報にみられるように、遮音シートを介層した合板の下面に防振ゴム層を配して なる防音性床材が提案され実用されている。0004 In order to weaken the transmission of sound generated on this wooden flooring material, for example, As seen in the official publication, a vibration-proof rubber layer is placed on the underside of plywood with a sound-insulating sheet interposed. Soundproof flooring materials have been proposed and put into practical use.
【０００５】[0005]
上記のように下面に防振ゴム層を備えた床材はオクターブ帯域中心周波数とい われいてる音の強さ(Hz)が 500 Hz 以上の高周波音域において顕著な遮音性を発 するが、500 Hz以下の比較的低周波音域における遮音性にやや難点があり、低周 波音域において十分な遮音効果をあげようとすると防振ゴム層の硬度を低下しな ければならず、床板としての圧縮強度に影響が生じることになる。 As mentioned above, flooring materials with a vibration-proof rubber layer on the bottom surface are called octave band center frequency. It exhibits remarkable sound insulation properties in the high frequency range where the sound intensity (Hz) is 500 Hz or higher. However, there are some difficulties in sound insulation in the relatively low frequency sound range below 500 Hz, and In order to achieve a sufficient sound insulation effect in the wave sound range, the hardness of the anti-vibration rubber layer must be reduced. This will affect the compressive strength of the floorboard.
【０００６】 かかる不都合は防振ゴム層の厚さ寸法を大きくすることによって改善すること が可能であるが、防振ゴム層を厚くすると床板の厚さが増加し、また床板の厚さ を変えずに合板部を薄くすると床板の強度低下を招くという不都合が生じる。[0006] This disadvantage can be improved by increasing the thickness of the vibration-proof rubber layer. However, thickening the anti-vibration rubber layer increases the thickness of the floorboard, and If the plywood portion is made thinner without changing the thickness, there will be an inconvenience that the strength of the floorboard will decrease.
【０００７】 本考案は防振部の厚さ寸法を大きくすることなく上記難点が改善された防音性 床材を提供するものである。[0007] This invention provides soundproofing that improves the above drawbacks without increasing the thickness of the vibration isolating part. It provides flooring materials.
【０００８】[0008]
本考案者は、上記した床材基板の下面に配される吸音制振材とコンクリートス ラブ面との接触面積を小さくしてコンクリートスラブとの間に空間を形成するす るとともに吸音制振材部に空気を介在させることによって吸音制振効果が向上す ることができ、さらにコンクリートスラブ側の防振材層が軟質である程振動が吸 収できることに着目し、上記難点を改善した。 The inventor of the present invention proposed the above-mentioned sound-absorbing and vibration-damping material placed on the bottom surface of the flooring substrate and the concrete slab. To reduce the contact area with the rub surface and create a space between it and the concrete slab. At the same time, the sound absorption and vibration damping effect is improved by interposing air in the sound absorption and damping material. Furthermore, the softer the vibration isolating material layer on the concrete slab side, the more vibrations will be absorbed. We focused on the fact that it was possible to improve the above-mentioned difficulties.
【０００９】 即ち本考案の積層防音床材は、底面側に位置する弾性材料の防振材層の下面に 多数の短柱状突起を設けてコンクリートスラブとの間に空間を形成するとともに 該防振材層の下面側を上面側よりも軟質となし、該防振材層の上面側に１平方米 当たりの目付が 50 〜200 g の不織布を貼り合わせて該防振材層と該布とによっ て構成した吸音制振部に空気を介在させ、該吸音制振部の不織布上に、木質板と 中間遮音シートと木質化粧板とが一体化された木質床材基板を貼り合わせて積層 防音床材を構成してなる。[0009] In other words, the laminated soundproof flooring material of the present invention has A large number of short pillar-shaped protrusions are provided to create a space between the concrete slab and the concrete slab. The lower surface side of the vibration isolating material layer is made softer than the upper surface side, and 1 square meter is placed on the upper surface side of the vibration isolating material layer. Nonwoven fabrics with a per unit weight of 50 to 200 g are bonded together and the vibration isolating material layer and the fabric are bonded together. air is interposed in the sound absorption and vibration damping part constructed of Laminated by laminating wooden flooring substrates with integrated intermediate sound insulation sheet and wooden decorative board. Consists of soundproof flooring material.
【００１０】 上記防振材層は天然ゴム、合成ゴム、発泡ゴム、発泡合成樹脂の成形物の単独 または異種成形物の貼り合わせ材が用いられ、ショアー硬度において上面側が40 〜65 度、下面側が20〜40度程度となるように構成するとよい。全体が柔軟過ぎ る と床沈みが発生し、また硬すぎると衝撃エネルギーの緩和効果の低下を招く。防 振材層の下面の突起は高さ2 〜5mm の円柱形、角柱形、円錐台形、角錐台形等の 短柱形状をなし、これらは間隔をおいて多数一体的に形成され、全突起の底面と コンクリートスラブとの接触面積の割合は15〜50％、好ましくは20〜35％である 。0010 The above vibration isolating material layer is a single molded product of natural rubber, synthetic rubber, foamed rubber, or foamed synthetic resin. Alternatively, a bonded material of dissimilar moldings is used, and the upper surface side has a Shore hardness of 40 It is best to configure the angle so that the angle is ~65 degrees and the bottom side is around 20~40 degrees. Everything is too flexible Ru This will cause the floor to sink, and if it is too hard, it will reduce the impact energy mitigation effect. prevention The protrusions on the lower surface of the vibration material layer are cylindrical, prismatic, truncated conical, truncated pyramid, etc. with a height of 2 to 5 mm. It has a short column shape, and many of these are integrally formed at intervals, and the bottom surface of all projections and The percentage of contact area with the concrete slab is 15-50%, preferably 20-35% .
【００１１】 コンクリートスラブと突起底面との接触面積割合が50％以上となると、荷重に よる単位面積当たり伸縮変形量が小さくなり、床材上に加えられた衝撃エネルギ ーを緩和する効果と空間による吸音効果が少なくなってコンクリートスラブ側へ の衝撃音の伝達抑止性が低下する。また15％以下の場合は、衝撃音の伝達抑止性 が向上するが、荷重による単位面積当たり伸縮変形量が過大となり床沈みが生じ 、床材として不適当となる。[0011] When the contact area ratio between the concrete slab and the bottom of the protrusion exceeds 50%, the load The amount of expansion/contraction deformation per unit area becomes smaller due to the impact energy applied to the flooring material. The effect of alleviating the noise and the sound absorption effect of the space are reduced and the sound is transferred to the concrete slab side. The ability to suppress impact sound transmission is reduced. In addition, if it is 15% or less, impact sound transmission suppression However, the amount of expansion/contraction deformation per unit area due to the load is excessive and floor sinking occurs. , making it unsuitable as flooring material.
【００１２】 また一つの突起のコンクリートスラブ面との接触面積は 3〜100 平方粍程度好 ましくは 7〜50平方粍であり、かかる突起の多数によって上記した15％以上50％ 以下の接触面積が保持されている。0012 In addition, the contact area of one protrusion with the concrete slab surface is approximately 3 to 100 square millimeters. Preferably from 7 to 50 square millimeters, and depending on the number of such protrusions, the above 15% or more and 50% The following contact areas are maintained:
【００１３】 防振材層の上面側に貼り付ける吸音制振材の１つである不織布は、太さが1 〜 20デニールの熱可塑性繊維の単独またはセルロース繊維が混合された１平方米当 たりの目付が 50 〜200 g のニードルパンチング不織布が好適であり、１平方米 たりの目付が 200g 以下では 250 Hz の振動音の吸音効果が乏しく、また１平方 米当たりの目付が 200g 以上となると床板全体の厚さが過大となる。その他木質 板と中間シートおよび木質化粧板とが一体化された木質床材基板には、市販の床 材が使用することができる。[0013] The non-woven fabric, which is one of the sound-absorbing and vibration-damping materials that is pasted on the top side of the vibration-proofing material layer, has a thickness of 1 to 1. 20 denier thermoplastic fiber alone or mixed with cellulose fiber per square meter Needle-punched non-woven fabric with a basis weight of 50 to 200 g is suitable. If the weight of the material is less than 200g, the sound absorption effect for 250 Hz vibration sound is poor, and If the basis weight per rice is 200g or more, the thickness of the entire floorboard will be excessive. Other wood Commercially available flooring substrates, which are integrated with boards, intermediate sheets, and decorative wood boards, are material can be used.
【００１４】[0014]
本考案の積層防音床材は、化粧木質板上で発生した衝撃音の振動をゴム系の制 振材で吸収減衰しさらに、その下部に配設されるニードルパンチング不織布ゾー ンと、さらにその下部に配設された防振材層で振動を吸収減衰させ、コンクリー トスラブへの振動伝達を緩和する。 The laminated soundproof flooring material of this invention uses rubber-based control to suppress the vibrations of impact sounds generated on decorative wood boards. The vibration material absorbs and damps the material, and the needle-punched non-woven fabric zone located below it. The vibration is absorbed and attenuated by the vibration isolating material layer placed below the concrete. Alleviates vibration transmission to the toss slab.
【００１５】 即ち、吸音制振材構成材料の一つであるニードルパンチを施した不織布は、12 5 〜2000 Hz 間の振動減衰に役立ち、防振材層とその下面の突起並びに空間は防 振並びに衝撃音のコンクリートスラブへの伝達緩和を行い、63〜2000 H■ の騒 音を顕著に減衰させる。[0015] In other words, the needle-punched nonwoven fabric, which is one of the constituent materials of the sound absorbing and damping material, is 12 It is useful for damping vibrations between 5 and 2000 Hz, and the vibration isolating material layer and the protrusions and spaces on its lower surface are The transmission of vibration and impact sound to the concrete slab is alleviated, and noise of 63 to 2000 H■ is Significantly attenuates sound.

本考案は、マンション等の防音床材に関し、特に 250 Hz 以下の低周波音を効 的に制振する木質系防音床材に関するものである。 This invention relates to soundproof flooring materials for condominiums, etc., and is particularly effective against low-frequency sounds below 250 Hz. This article relates to a wood-based soundproof flooring material that effectively damps vibrations.

ホテルやマンションでは、特に上階の部屋での人の歩行や子供の跳びはね音、 椅子を移動させる時に発生する個体音等騒音が居住性の悪化を招く大きな要因と なっている。上記騒音の原因はすべてが振動であり、人が歩行したり、跳びはね る時の振動がコンクリートスラブに伝達されて発生するものであり、これらの音 の振動波が伝わらないように従来からカーペットや絨毯を敷くなどの種々な工夫 がなされている。 In hotels and condominiums, the noise of people walking and children jumping, especially in rooms on the upper floors, Noise such as individual sounds generated when moving chairs is a major cause of deterioration of livability. It has become. All of the above noises are caused by vibrations, such as people walking or jumping. These sounds are generated when vibrations are transmitted to the concrete slab. Conventionally, various methods such as laying carpets or rugs have been used to prevent the vibration waves from being transmitted. is being done.
【０００３】 一方近年においてはカーペットや絨毯に代えて木質床材が好まれ、そのため階 下への衝撃音の伝達がより顕著となっている。このことを考慮して建築時におい て床下部分に木製または鋼製の根太を用い、その上に床材を張る工法が実施され ているが、この程度では上階の音を十分遮音することはできない。0003 On the other hand, in recent years, wooden flooring has become preferred in place of carpets and rugs, and as a result, floor The transmission of impact sound downwards is more pronounced. This should be taken into consideration during construction. A construction method has been implemented in which wooden or steel joists are used at the bottom of the floor, and flooring material is placed on top of the wooden or steel joists. However, this level is not sufficient to block out the sound from the floors above.
【０００４】 この木質床材上で発生する音の伝達を弱めるべく、例えば実開昭63-119740 号 公報にみられるように、遮音シートを介層した合板の下面に防振ゴム層を配して なる防音性床材が提案され実用されている。0004 In order to weaken the transmission of sound generated on this wooden flooring material, for example, As seen in the official publication, a vibration-proof rubber layer is placed on the underside of plywood with a sound-insulating sheet interposed. Soundproof flooring materials have been proposed and put into practical use.
【０００５】[0005]
上記のように下面に防振ゴム層を備えた床材はオクターブ帯域中心周波数とい われてる音の強さ(Hz)が 500 Hz 以上の高周波音域において顕著な遮音性を発揮 するが、500 Hz以下の比較的低周波音域における遮音性にやや難点があり、低周 波音域において十分な遮音効果をあげようとすると防振ゴム層の硬度を低下しな ければならず、床板としての圧縮強度に影響が生じることになる。 As mentioned above, flooring materials with a vibration-proof rubber layer on the bottom surface are called octave band center frequency. Demonstrates outstanding sound insulation properties in high-frequency sound ranges with a sound intensity (Hz) of 500 Hz or higher. However, there are some difficulties in sound insulation in the relatively low frequency sound range below 500 Hz, and In order to achieve a sufficient sound insulation effect in the wave sound range, the hardness of the anti-vibration rubber layer must be reduced. This will affect the compressive strength of the floorboard.
【０００６】 かかる不都合は防振ゴム層の厚さ寸法を大きくすることによって改善すること が可能であるが、防振ゴム層を厚くすると床板の厚さが増加し、また床板の厚さ を変えずに合板部を薄くすると床板の強度低下を招くという不都合が生じる。[0006] This disadvantage can be improved by increasing the thickness of the vibration-proof rubber layer. However, thickening the anti-vibration rubber layer increases the thickness of the floorboard, and If the plywood portion is made thinner without changing the thickness, there will be an inconvenience that the strength of the floorboard will decrease.
【０００７】 本考案は防振部の厚さ寸法を大きくすることなく上記難点が改善された防音性 床材を提供するものである。[0007] This invention provides soundproofing that improves the above drawbacks without increasing the thickness of the vibration isolating part. It provides flooring materials.

本考案者は、上記した床材基板の下面に配される吸音制振材とコンクリートス ラブ面との接触面積を小さくしてコンクリートスラブとの間に空間を形成するす るとともに吸音制振材部に空気を介在させることによって吸音制振効果が向上す ることができ、さらにコンクリートスラブ側の防振材層が軟質である程振動が吸 収できることに着目し、上記難点を改善した。 The inventor of the present invention proposed the above-mentioned sound-absorbing and vibration-damping material placed on the bottom surface of the flooring substrate and the concrete slab. To reduce the contact area with the rub surface and create a space between it and the concrete slab. At the same time, the sound absorption and vibration damping effect is improved by interposing air in the sound absorption and damping material. Furthermore, the softer the vibration isolating material layer on the concrete slab side, the more vibrations will be absorbed. We focused on the fact that it was possible to improve the above-mentioned difficulties.
【０００９】 即ち本考案の積層防音床材は、底面側に位置する弾性材料の防振材層の下面に 多数の短柱状突起を設けてコンクリートスラブとの間に空間を形成するとともに 該防振材層の下面側を上面側よりも軟質となし、該防振材層の上面側に１平方米 当たりの目付が 50 〜200 g の不織布を貼り合わせて該防振材層と該不織布とに よって構成した吸音制振部に空気を介在させ、該吸音制振部の不織布上に、木質 板と中間遮音シートと木質化粧板とが一体化された木質床材基板を貼り合わせて 積層防音床材を構成してなる。[0009] In other words, the laminated soundproof flooring material of the present invention has A large number of short pillar-shaped protrusions are provided to create a space between the concrete slab and the concrete slab. The lower surface side of the vibration isolating material layer is made softer than the upper surface side, and 1 square meter is placed on the upper surface side of the vibration isolating material layer. Nonwoven fabrics with a per unit weight of 50 to 200 g are bonded together and the vibration isolating material layer and the nonwoven fabric are bonded together. Therefore, air is interposed in the sound absorbing and damping part, and a wooden material is placed on the nonwoven fabric of the sound absorbing and damping part. A wooden flooring board that is an integrated board, intermediate sound insulation sheet, and wooden decorative board is pasted together. Consists of laminated soundproof flooring.
【００１０】 上記防振材層は天然ゴム、合成ゴム、発泡ゴム、発泡合成樹脂の成形物の単独 または異種成形物の貼り合わせ材が用いられ、ショアー硬度において上面側が40 〜65 度、下面側が20〜40度程度となるように構成するとよい。全体が柔軟過ぎ ると床沈みが発生し、また硬すぎると衝撃エネルギーの緩和効果の低下を招く。 防振材層の下面の突起は高さ2 〜5mm の円柱形、角柱形、円錐台形、角錐台形等 の短柱形状をなし、これらは間隔をおいて多数一体的に形成され、全突起の底面 とコンクリートスラブとの接触面積の割合は15〜50％、好ましくは20〜35％であ る。0010 The above vibration isolating material layer is a single molded product of natural rubber, synthetic rubber, foamed rubber, or foamed synthetic resin. Alternatively, a bonded material of dissimilar moldings is used, and the upper surface side has a Shore hardness of 40 It is best to configure the angle so that the angle is ~65 degrees and the bottom side is around 20~40 degrees. Everything is too flexible If it is too hard, the floor will sink, and if it is too hard, it will reduce the effect of mitigating impact energy. The protrusions on the bottom surface of the vibration isolating material layer have a height of 2 to 5 mm and are cylindrical, prismatic, truncated cone, truncated pyramid, etc. It has the shape of a short column, and these are integrally formed in large numbers at intervals, and the bottom surface of all the protrusions is The proportion of the contact area between the concrete slab and the concrete slab is 15-50%, preferably 20-35%.

【００１１】 コンクリートスラブと突起底面との接触面積割合が50％以上となると、荷重に よる単位面積当たり伸縮変形量が小さくなり、床材上に加えられた衝撃エネルギ ーを緩和する効果と空間による吸音効果が少なくなってコンクリートスラブ側へ の衝撃音の伝達抑止性が低下する。また15％以下の場合は、衝撃音の伝達抑止性 が向上するが、荷重による単位面積当たり伸縮変形量が過大となり床沈みが生じ 、床材として不適当となる。[0011] When the contact area ratio between the concrete slab and the bottom of the protrusion exceeds 50%, the load The amount of expansion/contraction deformation per unit area becomes smaller due to the impact energy applied to the flooring material. The effect of alleviating the noise and the sound absorption effect of the space are reduced and the sound is transferred to the concrete slab side. The ability to suppress impact sound transmission is reduced. In addition, if it is 15% or less, impact sound transmission suppression However, the amount of expansion/contraction deformation per unit area due to the load is excessive and floor sinking occurs. , making it unsuitable as flooring material.
