本考案は多層建築物において、上階で発生した振動や騒音の階下への伝達を防 止し得る新規な床下地パネルに関する。 This invention prevents vibrations and noise generated on the upper floors from being transmitted to the lower floors in multi-story buildings. The present invention relates to a new floor sub-base panel that can be stopped.
【０００２】0002
一般に、上階から床を伝通して伝播する騒音はＪＩＳ−Ａ１４１８に記載され ている如く、軽量衝撃音と重量衝撃音とに大別される。これらの衝撃音を防止す る手法は基本的に異なるものとされている。すなわち硬質の衝撃体により発生す る軽量衝撃音は高周波領域にあるため、床構造には高周波の吸収能力が要求され 、通常カーペット、畳などの柔軟な仕上げ材を用いることが有効であるとされて いる。軟質の衝撃体により発生する重量性の衝撃音は低周波領域にあり、床構造 には低周波の吸収能力が要求され、通常、床構造の質量を上げる方法が有効な手 段とされている。 近年、木質系仕上げ材（木質フローリング），石板系仕上げ材など表面緩衝効 果の低い仕上げ材の普及に伴い、軽量衝撃音に対する問題が取り上げられている 。前記問題を解決する方法の一つとして、仕上げ材と床基盤との間に防振性を付 与させた床下地パネルを配置する方法が用いられている。該床下地パネルは、防 振性付与の為、板材の下面にグラスウール，ロックウール等の繊維状物、あるい は防振ゴム等を貼設したものがもちいられているが、グラスウール、ロックウー ル等の繊維状物は床下地用部材として用いたとき重量物などの荷重により大きく 変形すること、また荷重を除いても変形が復元しない、また防振ゴムなどは軽量 衝撃音に対する低減効果が乏しいといった問題をそれぞれ有している。 繊維状物を用いた床下地パネルに対しては、繊維状物の密度を上げ圧縮強度を 向上させる方法、適当な間隔で補強用の桟を用い桟と桟との間に繊維状物を充填 する方法などが取られているが、前者は軽量衝撃音に対する低減効果が減少し、 後者も又振動が補強用桟を介して階下へ伝達されるため低減効果が減少すること から問題の解決には到っていない。 In general, noise that propagates from the upper floor through the floor is described in JIS-A1418. As shown in the figure, sound is broadly divided into light impact sound and heavy impact sound. To prevent these impact sounds, The methods used are fundamentally different. In other words, the impact generated by a hard impact body Since light impact sound is in the high frequency range, the floor structure is required to have the ability to absorb high frequencies. , it is generally considered effective to use flexible finishing materials such as carpets and tatami mats. There is. Heavy impact noise generated by soft impact bodies is in the low frequency range, and requires low-frequency absorption ability, and increasing the mass of the floor structure is usually an effective method. It is said to be tiered. In recent years, surface cushioning materials such as wood-based finishing materials (wood flooring) and stone slab-based finishing materials have been developed. With the spread of low-impact finishing materials, the issue of lightweight impact noise has been raised. . One way to solve the above problem is to add vibration isolation between the finishing material and the floor base. A method of arranging subfloor panels given the following conditions is used. The floor sub-panel is To impart vibrational properties, a fibrous material such as glass wool or rock wool is placed on the bottom surface of the board. are used with anti-vibration rubber, etc., but glass wool, rock wool etc. When fibrous materials such as rubber are used as flooring materials, they can become large due to the load of heavy objects. The deformation may not be restored even after the load is removed, and anti-vibration rubber etc. are lightweight. Each of these methods has the problem of being insufficiently effective in reducing impact noise. For subfloor panels using fibrous materials, the density of the fibrous material is increased to increase the compressive strength. A method to improve However, the former method reduces the reduction effect on lightweight impact noise, In the latter case, the vibration reduction effect is also reduced because the vibration is transmitted to the downstairs via the reinforcing crosspiece. Since then, the problem has not been resolved.

本考案はかかる点に鑑みなされたもので、その目的とするところは、床下地パ ネルとして軽量床衝撃音低減効果に優れ、且つ重量物などの荷重に対する充分な る耐久性を兼ね備えた床下地材パネルについて種々検討を重ねた結果、天然もし くは合成樹脂フィラメントを３次元的に交絡してなる立体網状構造体を桟として 用いることによりその繊維が交絡した立体構造の故に、良好な振動エネルギーの 遮断性能を示し、かつへたりにくい特性を有していることを見出し、本考案を完 成するに到った。 The present invention was devised in view of these points, and its purpose is to As a flannel, it has an excellent effect of reducing impact noise on lightweight floors, and has sufficient resistance to loads such as heavy objects. As a result of various studies on floor sub-material panels that have the durability of A three-dimensional network structure made of three-dimensionally intertwined synthetic resin filaments is used as a crosspiece. Due to the intertwined three-dimensional structure of its fibers, it has good vibrational energy. After discovering that it exhibits breaking performance and has the property of being resistant to deterioration, we completed this invention. It has come to fruition.

【０００５】 以下に添付の図面に基づき本考案を説明する。図１乃至図５は本考案に係る床 下地パネルにおける構造例を示す断面図である。 図１に示す床下地パネルは上層板材１と下層板材２との間に桟としての網状構 造体３を挿入したものであり、図２は立体網状構造体３の上下にレベル調整を目 的とした板材４を貼設した桟を用い、且つ下層板材２の下面に不陸調整用の緩衝 シート５を貼着して形成したものであり、図３は図２の桟と桟との間に繊維状物 ６を充填したものである。図４は桟として用いられる立体網状構造体３を板材４ を介して二重に用いたものである。図５は図１の構造に加え上層板材１の上面に 立体網状構造体３，さらに板材７を貼設し、図６は図１の構成に加え下層板材２ の立体網状構造体３を貼設した構造を示す。なお、本考案に係る床下地パネルは これらの構成例に限られるものではなく、上層板材，下層板材，桟より構成され 、前記桟が少なくとも天然もしくは合成樹脂フィラメントを３次元的に交絡して なる立体網状構造体からなるものであれば積層構造は特に限定されない。[0005] The present invention will be described below with reference to the accompanying drawings. Figures 1 to 5 are floors according to the present invention. FIG. 3 is a cross-sectional view showing a structural example of a base panel. The subfloor panel shown in Figure 1 has a net-like structure as a crosspiece between an upper layer 1 and a lower layer 2. Fig. 2 shows the level adjustment above and below the three-dimensional network structure 3. Using a crosspiece on which the target board material 4 is pasted, and on the bottom surface of the lower board material 2, a buffer for unevenness adjustment is used. It is formed by pasting the sheet 5, and FIG. 3 shows a fibrous material between the bars in FIG. 2. 6. Figure 4 shows a three-dimensional network structure 3 used as a crosspiece with a plate material 4. It was used twice through the . In addition to the structure shown in Fig. 1, Fig. 5 shows the top surface of the upper layer plate 1. The three-dimensional network structure 3 and the plate material 7 are pasted, and FIG. 6 shows the structure shown in FIG. This shows a structure in which a three-dimensional network structure 3 is pasted. In addition, the floor base panel according to this invention is The structure is not limited to these examples, but may be composed of an upper layer plate, a lower layer plate, and a crosspiece. , the crosspiece has at least three-dimensionally entangled natural or synthetic resin filaments. The laminated structure is not particularly limited as long as it is composed of a three-dimensional network structure.
【０００６】 図７，図８及び図９は比較例としての構成を示す。図７は上層板材１の下面に 繊維状物６を貼設したものである。図８は上層板材１と下層板材２との間に繊維 状物６を挿入し、下層板材２の下面に不陸調整用の緩衝シート５を貼着したもの であり、図９は図８の構造に対し、補強用の木桟８を挿入したものである。図１ ０は床下地パネルの平面図を示し、図中破線は桟の位置を示す。 桟の幅は通常３０〜３００mm程度、好ましくは５０〜１５０mm程度のものが使 用されるが、これらに限定されるものではない。桟の幅、ピッチは桟上に載置さ れる板材の剛性などにより適宜選定すればよい。 立体網状構造体３の片面または両面には積層が容易になるようプラスチックシ ート、ゴムシート、不織布などのシート状物を貼設しても良い。これら立体網状 構造体３は比較的剛性に富んだ天然もしくは合成樹脂フィラメントを立体的に交 絡して作られた立体網状構造体の中で、非共振，非強制振動型の動的こわさ試験 機を用いて、常温で１００N／cm2・cm以下の値を示す構造体が好ましく、この値 は低ければ低いほど良い。この値が１００N／cm2・cmを超えると衝撃音の緩衝効 果は充分でなくなるからである。FIGS. 7, 8, and 9 show configurations as comparative examples. In FIG. 7, a fibrous material 6 is attached to the lower surface of the upper plate material 1. Fig. 8 shows a structure in which a fibrous material 6 is inserted between the upper plate material 1 and the lower plate material 2, and a buffer sheet 5 for unevenness adjustment is attached to the lower surface of the lower plate material 2, and Fig. 9 shows the structure shown in Fig. 8. A wooden crosspiece 8 for reinforcement is inserted into the structure. Figure 10 shows a plan view of the subfloor panel, and the broken lines in the figure indicate the positions of the crosspieces. The width of the crosspiece is usually about 30 to 300 mm, preferably about 50 to 150 mm, but is not limited to this. The width and pitch of the crosspieces may be appropriately selected depending on the rigidity of the plate material placed on the crosspieces. A sheet-like material such as a plastic sheet, a rubber sheet, or a nonwoven fabric may be attached to one or both surfaces of the three-dimensional network structure 3 to facilitate lamination. These three-dimensional network structures 3 are constructed by three-dimensionally entangling natural or synthetic resin filaments with relatively high rigidity, and a non-resonant, non-forced vibration type dynamic stiffness tester is used in the three-dimensional network structures 3. A structure exhibiting a value of 100 N/cm 2 ·cm or less at room temperature is preferable, and the lower this value is, the better. This is because if this value exceeds 100N/cm 2 cm, the impact sound buffering effect will not be sufficient.
【０００７】 本考案の１００N／cm2・cm以下を示す構造体としては、６ナイロン、６６ナイ ロンなどのナイロン類、ポリプロピレン、硬質，半硬質のポリ塩化ビニル、ポリ アセタール、ポリエステル樹脂のフィラメントが挙げられる。低密度ポリエチレ ン・酢酸ビニル共重合体、ＡＢＳ樹脂、ゴム変性ポリスチレン等のフィラメント は“こわさ”が不足するので一部の範囲からなる立体網状構造体が含まれる。 また、パームなどの天然の繊維の中の或種の範囲の剛性のものが、本考案の数 値内に該当する網状構造体として利用することが出来る。しかし、天然の剛性に 富む繊維は集合住宅などに用いた場合、換気が不十分になって‘ダニ’などの発 生を助長させたり、強いアルカリ性湿気の故に強度を低下させたりする恐れがあ るので、使用前に樹脂含浸処理等の対策を施すことが好ましい。この意味から合 成樹脂フィラメントからなる立体網状構造体は、より好ましい材料であって本考 案の骨格をなすのものである。 これら立体網状構造体のフィラメントの径は材質によっても異なるが、網状構 造体が１００N／cm2・cm以下の物性値を持つためには通常０．２mm〜３mmφの径 のものが用いられる。これよりも径が細いと如何に網状構造が密でも荷重や衝撃 によって変形してしまって効果を発現できない。又、３mm以上の径では剛性に富 み過ぎて、衝撃音を緩和するような挙動を示さない材料が多い。又、立体網状構 造体の厚みは２mm以上であり、２mm以下では衝撃音の低減効果が乏しくなる。[0007] Examples of structures exhibiting 100 N/cm 2 cm or less of the present invention include filaments of nylons such as nylon 6 and nylon 66, polypropylene, rigid and semi-rigid polyvinyl chloride, polyacetal, and polyester resins. . Filaments made of low-density polyethylene/vinyl acetate copolymer, ABS resin, rubber-modified polystyrene, etc. lack "stiffness", so a three-dimensional network structure consisting of a certain range is included. Also, certain ranges of stiffness among natural fibers, such as palm, can be utilized as a network structure that falls within the numerical values of the present invention. However, when natural, highly rigid fibers are used in housing complexes, there is a risk that ventilation will be inadequate, encouraging the growth of dust mites, and strong alkaline moisture may reduce strength. It is preferable to take measures such as resin impregnation treatment before use. In this sense, a three-dimensional network structure made of synthetic resin filaments is a more preferable material and forms the backbone of the present invention. The diameter of the filaments of these three-dimensional network structures varies depending on the material, but in order for the network structure to have physical properties of 100 N/cm 2 ·cm or less, filaments with a diameter of 0.2 mm to 3 mmφ are usually used. If the diameter is smaller than this, no matter how dense the network structure is, it will be deformed by load or impact and will not be effective. Furthermore, many materials with a diameter of 3 mm or more are too rigid and do not behave in a way that alleviates impact noise. Further, the thickness of the three-dimensional network structure is 2 mm or more, and if it is less than 2 mm, the effect of reducing impact noise will be poor.
【０００８】 衝撃音の低減効果を上げる為、図４に示す如く桟に用いる立体網状構造体を多 層にして用いることができ、図５に示す如く上層板材の上部に立体網状構造体、 さらに板材を貼設しても良く、又図６に示す構造であっても良い。図３に示す桟 と桟との間に充填される繊維状物６はグラスウール、ロックウール、フェルト、 不織布など、及びこれらを複合したものが用いられる。これら繊維状物は断熱効 果、さらには立体網状構造体を構成要因とする桟との組み合わせにより軽量衝撃 音をさらに低減させる効果もある。 床下地パネルを構成する上層板材１、下層板材２は、合板、パーチクルボード 、ハードボード、杉板等の天然木材、プラスチックボード、窯業系ボードなど、 及びこれらを複合したものが用いられる。さらには緩衝、制振効果を有する可撓 性シート状物を付加したものであってもよい。これらの板材の厚みは種類、又仕 上げ板材等の仕様により異なるが、通常２〜５０mm程度、好ましくは４〜３０mm 程度のものが用いられる。パネルの配置は、相互のパネルが密接しても、間隔を 有してもよい。 床下地パネルの上部には木質フローリングを載置するのが一般的であるが、床 暖房用ユニットでもよく、又、振動を発生する設備ユニットであってもよい。さ らに、本考案に係るパネルは壁材として用いることも出来る。[0008] In order to increase the effect of reducing impact noise, multiple three-dimensional net structures are used for the crosspieces as shown in Figure 4. It can be used as a layer, and as shown in Figure 5, a three-dimensional network structure, Furthermore, a plate material may be attached, or the structure shown in FIG. 6 may be used. The crosspiece shown in Figure 3 The fibrous material 6 filled between the frame and the crosspiece may be glass wool, rock wool, felt, Nonwoven fabrics, etc., and composites of these are used. These fibrous materials have a heat insulating effect. In addition, the combination of crosspieces with a three-dimensional net structure as a component allows for lightweight impact resistance. It also has the effect of further reducing sound. Upper layer board material 1 and lower layer board material 2 that make up the floor base panel are plywood or particle board. , hardboard, natural wood such as cedar board, plastic board, ceramic board, etc. and a combination of these are used. Furthermore, it is flexible and has a cushioning and vibration damping effect. It is also possible to add a sheet-like material. The thickness of these plates depends on the type and finish. Although it varies depending on the specifications of the raised plate material, etc., it is usually about 2 to 50 mm, preferably 4 to 30 mm. A certain degree is used. The arrangement of panels should be such that even if the panels are close together, they should be spaced closely. May have. It is common to place wood flooring on top of the floor base panel, but It may be a heating unit, or it may be an equipment unit that generates vibrations. difference Furthermore, the panel according to the present invention can also be used as a wall material.
