Description

本発明は、防音性能を有する壁構造に関するものである。 The present invention relates to a wall structure having soundproofing performance.

鉄道や道路において、車両が走行する際に生じる騒音が外部に伝播するのを防ぐために、防音壁が設けられている。
従来の防音壁としては、重量の大きなコンクリート製の防音壁が用いられている。
しかし、コンクリートは経年劣化があり、また重量が大きく高架橋等の下部の構造体への負荷も大きい。
このため、近年は、軽量な繊維強化樹脂（ＦＲＰ）製の防音壁がコンクリート製の防音壁に代わって採用されるようになっている。 A noise barrier is provided on a railroad or a road to prevent noise generated when a vehicle travels from propagating to the outside.
As a conventional soundproof wall, a heavy soundproof wall made of concrete is used.
However, concrete has deteriorated over time, and the weight is large, and the load on the underlying structures such as viaducts is large.
For this reason, in recent years, lightweight soundproof walls made of fiber reinforced resin (FRP) have been adopted in place of concrete soundproof walls.

以下、図面を参照しながら本発明の実施の形態について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

［実施例１］
＜１＞防音壁の構成
本発明の防音壁は、ＦＲＰ壁材１と、ＦＲＰ壁材１の表面に配置する吸音体２を組み合わせて構成する（図１）。 [Example 1]
<1> Configuration of Soundproof Wall The soundproof wall of the present invention is configured by combining the FRP wall material 1 and the sound absorber 2 arranged on the surface of the FRP wall material 1 (FIG. 1 ).

ＦＲＰ壁材１は、平面視矩形の平板状の壁面板１１と、壁面板１１の表面に高さ方向に亘って突設するリブ１２と、リブ１２と平行な壁面板１１の側辺に設けるフランジ１３と、からなる（図２）。
壁面板１１と、リブ１２、フランジ１３は、一体成形とする。
ＦＲＰ壁材１は、立設する構造体に打設したアンカーボルト３１にアングル３及び固定ボルト３２、固定ナット３３を介して立設する（図３）。なお、ＦＲＰ壁材１の立設方法はこの方法に限定されない。 <2> FRP wall material The FRP wall material 1 is a member made of fiber reinforced resin (FRP) or glass fiber reinforced resin (GFRP).
The FRP wall material 1 is provided on a flat plate-like wall plate 11 having a rectangular shape in a plan view, ribs 12 projecting from the surface of the wall plate 11 in the height direction, and on the sides of the wall plate 11 parallel to the ribs 12. And a flange 13 (FIG. 2).
The wall plate 11, the rib 12 and the flange 13 are integrally formed.
The FRP wall material 1 is erected on the anchor bolts 31 cast on the erected structure via the angles 3, the fixing bolts 32, and the fixing nuts 33 (FIG. 3). The method of standing the FRP wall material 1 is not limited to this method.

＜２．１＞リブ
リブ１２は平面視Ｔ字状の部材である。
複数のＦＲＰ壁材１を立設したときに、リブ１２が等間隔に並列するように、壁面板１１の側辺からリブ１２までの長さと隣り合うリブ１２の間隔を設定する。 <2.1> Rib The rib 12 is a T-shaped member in a plan view.
When the plurality of FRP wall materials 1 are erected, the lengths from the side edges of the wall surface plate 11 to the ribs 12 and the intervals between the adjacent ribs 12 are set so that the ribs 12 are juxtaposed at equal intervals.

＜２．２＞フランジ
フランジ１３は平板状であり、壁面板１１の側辺の表面から、壁面板１１と平行に突設する。
複数のＦＲＰ壁材１の側辺同士を合わせて立設したときに、側辺同士の接合部分の表面にフランジ１３が位置する。
フランジ１３を設けることにより、ＦＲＰ壁材１同士の隙間がなくなり、ＦＲＰ壁材１の面に直交する方向に作用する力が、フランジ１３を介して隣接するＦＲＰ壁材１に分散される（図４）。 <2.2> Flange The flange 13 has a flat plate shape, and is provided so as to project from the side surface of the wall plate 11 in parallel with the wall plate 11.
When the side edges of the plurality of FRP wall materials 1 are erected so as to be aligned with each other, the flange 13 is located on the surface of the joint portion between the side edges.
By providing the flange 13, the gap between the FRP wall materials 1 is eliminated, and the force acting in the direction orthogonal to the surface of the FRP wall material 1 is dispersed to the adjacent FRP wall material 1 via the flange 13 (Fig. 4).

＜３＞吸音体
吸音体２は、入射した音のエネルギーを熱エネルギーに変換することにより、反射する音のエネルギーを減らすものである。
吸音体２は、ポリエステル繊維不織布を矩形の板状に形成した母材２１と、母材２１の少なくとも音響入射側にポリエステル繊維スパンボンド不織布からなる表面材２２を熱融着して一体とした複合吸音体であり（図５）、優れた吸音性能を発揮する。また、表面材２２には撥水処理を施すことにより、母材２１の保護材にもなる。表面材２２は、母材２１の音響入射側に限らず、表面全面に設けてもよい。
吸音体２の構成素材であるポリエステル繊維不織布は、軽量で優れた吸音性能を有し、リサイクルができるため地球環境に優しく、また、耐候性、耐久性、耐水性、耐薬品性にも優れ、長期的に安定して使用できる材料である。
吸音体２は、立設したＦＲＰ壁材１のうち、一枚のＦＲＰ壁材１に並列するリブ１２間や、二枚並べて立設したＦＲＰ壁材１のそれぞれのリブ１２間に配置する。
吸音体２の大きさは、高さ方向はＦＲＰ壁材１の高さよりも短くし、幅方向は、並列したリブ１２の間隔と略同一とし、奥行き方向は、突設するリブ１２の高さよりも短くする。 <3> Sound Absorbing Body The sound absorbing body 2 reduces energy of reflected sound by converting energy of incident sound into heat energy.
The sound absorbing body 2 is a composite body in which a base material 21 formed of a polyester fiber non-woven fabric in a rectangular plate shape and a surface material 22 made of polyester fiber spun-bonded non-woven fabric are heat-fused at least on the sound incident side of the base material 21 to be integrated. It is a sound absorbing body (Fig. 5) and exhibits excellent sound absorbing performance. Further, the surface material 22 becomes a protective material for the base material 21 by applying a water repellent treatment. The surface material 22 is not limited to the sound incident side of the base material 21, and may be provided on the entire surface.
The polyester fiber non-woven fabric, which is the constituent material of the sound absorber 2, is lightweight, has excellent sound absorbing performance, and is environmentally friendly because it can be recycled, and also has excellent weather resistance, durability, water resistance, and chemical resistance. It is a material that can be used stably over the long term.
The sound absorbing body 2 is arranged between the ribs 12 of the FRP wall material 1 that are erected in parallel with one FRP wall material 1 or between the respective ribs 12 of the FRP wall material 1 that are erected side by side.
The size of the sound absorbing body 2 is shorter than the height of the FRP wall material 1 in the height direction, substantially the same as the interval between the ribs 12 arranged in parallel in the width direction, and the height of the protruding rib 12 in the depth direction. Also shorten.

＜３．１＞吸音体の保持
ＦＲＰ壁材１の壁面板１１と吸音体２との間は、隙間がないことが好ましい。
吸音体２の下端は、壁面板１１及びリブ１２に突設した支持材１４により支持する。
また、ＦＲＰ壁材１のリブ１２には、ＦＲＰ壁材１の高さ方向に沿って側部押さえ材１５を設ける。
側部押さえ材１５は断面視Ｌ字状とし、一辺をリブ１２に沿って固定し、他辺をリブ１２から突設する押さえ部とする。押さえ部は壁面板１１と平行とし、押さえ部と壁面板１１との間隔は、吸音体２の奥行きと略同一とする。これにより、吸音体２の側辺部分は側部押さえ材１５によって保持される。
支持材１４及び側部押さえ材１５はＦＲＰ壁材１と同じくＦＲＰ製とし、リベットやボルト、ナットを介してＦＲＰ壁材１に固定するのが好適である。
吸音体２は壁面材のリブ１２間に配置し、また、側辺部分を側部押さえ材１５により押さえるのみであり、露出部分が大きく、防音性能が高い防音壁となる。 <3.1> Holding of Sound Absorber It is preferable that there is no gap between the wall surface plate 11 of the FRP wall material 1 and the sound absorber 2.
The lower end of the sound absorber 2 is supported by the support member 14 provided on the wall plate 11 and the rib 12.
Further, the ribs 12 of the FRP wall material 1 are provided with side pressing members 15 along the height direction of the FRP wall material 1.
The side pressing member 15 is L-shaped in cross-section, one side is fixed along the rib 12, and the other side is a pressing portion protruding from the rib 12. The pressing portion is parallel to the wall surface plate 11, and the distance between the pressing portion and the wall surface plate 11 is substantially the same as the depth of the sound absorber 2. As a result, the side portion of the sound absorber 2 is held by the side pressing member 15.
It is preferable that the support member 14 and the side pressing member 15 are made of FRP, like the FRP wall member 1, and fixed to the FRP wall member 1 via rivets, bolts, and nuts.
The sound absorbing body 2 is arranged between the ribs 12 of the wall surface material, and the side portions are only pressed by the side pressing members 15, so that the sound absorbing wall has a large exposed portion and high soundproofing performance.

＜４＞上蓋
吸音体２は母材２１の表面に撥水処理を施した表面材２２を熱融着したポリエステル繊維系吸音材であるため、耐水性は保有するが、万が一水が内部に入りこむと水がしばらく保持される可能性がある。
このため、吸音体２を構成するポリエステル繊維の配向方向を一方向とし、配向方向をＦＲＰ壁材１に設置した際の高さ方向とすることにより、内部に入りこんだ水が繊維に沿って下方に流れ落ちやすくなるという特色が発揮され、速やかに排水される。
また、並列したＦＲＰ壁材１の上端には、上蓋１６を設ける。
上蓋１６は、並列したリブ１２の上端間に渡設し、リブ１２の上端に突設した上蓋支持材１６１に固定する。上蓋１６と上蓋支持材１６１はＦＲＰ壁材１と同じくＦＲＰ製又はＧＦＲＰ製とし、リベットを介して上蓋１６と上蓋支持材１６１を固定するのが好適である。
上蓋１６で吸音体２の上方を覆うことにより、吸音体２の内部に水が浸入するのを防止できる。 <4> Upper lid The sound absorbing body 2 is a polyester fiber-based sound absorbing material in which a surface material 22 having a water repellent treatment applied to the surface of a base material 21 is heat-sealed, so that it has water resistance, but by chance water enters inside. And water could be retained for a while.
For this reason, by setting the orientation direction of the polyester fibers constituting the sound absorber 2 to be one direction and the orientation direction to be the height direction when installed on the FRP wall material 1, the water that has entered the inside is lowered along the fibers. The feature is that it easily flows down to the water and is quickly drained.
An upper lid 16 is provided on the upper ends of the FRP wall materials 1 arranged in parallel.
The upper lid 16 is provided between the upper ends of the ribs 12 arranged in parallel, and is fixed to the upper lid support member 161 protruding from the upper ends of the ribs 12. The upper lid 16 and the upper lid supporting member 161 are preferably made of FRP or GFRP as with the FRP wall member 1, and it is preferable to fix the upper lid 16 and the upper lid supporting member 161 via rivets.
By covering the upper side of the sound absorbing body 2 with the upper lid 16, it is possible to prevent water from entering the inside of the sound absorbing body 2.

＜５＞防音壁の構築
＜５．１＞ＦＲＰ壁材の立設
次に、ＦＲＰ壁材１と吸音体２とを用いた防音壁の構築方法について説明する。
まず、壁面板１１、リブ１２、フランジ１３が一体成形され、予め支持材１４、側部押さえ材１５、上蓋支持材１６１を取り付けたＦＲＰ壁材１を並べて立設する（図６ａ）。
隣り合うＦＲＰ壁材１の接合部分の表面には、フランジ１３が位置する。
並列したＦＲＰ壁材１の表面には、等間隔にリブ１２が並列する。
ＦＲＰ壁材１は軽量であり、運搬や現場での設置作業が容易である。 <5> Construction of Soundproof Wall <5.1> Standing of FRP Wall Material Next, a method of constructing a soundproof wall using the FRP wall material 1 and the sound absorber 2 will be described.
First, the wall plate 11, the ribs 12, and the flange 13 are integrally molded, and the FRP wall material 1 to which the support material 14, the side pressing material 15, and the upper lid support material 161 are attached in advance is installed side by side (FIG. 6a).
The flange 13 is located on the surface of the joint portion between the adjacent FRP wall materials 1.
The ribs 12 are juxtaposed at equal intervals on the surface of the juxtaposed FRP wall materials 1.
The FRP wall material 1 is lightweight and easy to carry and install on site.

＜５．２＞吸音体の配置
次に、等間隔に並列するリブ１２の間であって、ＦＲＰ壁材１の表面と、側部押さえ材１５との間に、吸音体２を落とし込む（図６ｂ）。
吸音体２の下端は、壁面板１１及びリブ１２に突設した支持材１４により支持される。
吸音体２は軽量であり、運搬や現場での落とし込み作業が容易である。 <5.2> Arrangement of Sound Absorbing Body Next, the sound absorbing body 2 is dropped between the ribs 12 arranged at equal intervals and between the surface of the FRP wall material 1 and the side pressing material 15 (Fig. 6b).
The lower end of the sound absorber 2 is supported by the support member 14 provided on the wall plate 11 and the rib 12.
The sound absorbing body 2 is lightweight and easy to carry and drop on site.

＜５．３＞上蓋の設置
最後に、上蓋１６を並列したリブ１２の上端間に渡設し、リブ１２の上端に突設した上蓋支持材１６１に固定する（図６ｃ）。
上蓋１６はＦＲＰ製又はＧＦＲＰ製のため軽量であり、運搬や現場での設置作業が容易である。 <5.3> Installation of Upper Lid Finally, the upper lid 16 is provided between the upper ends of the ribs 12 arranged in parallel and fixed to the upper lid support member 161 protruding from the upper ends of the ribs 12 (FIG. 6c).
Since the upper lid 16 is made of FRP or GFRP, it is lightweight and easy to carry and install on site.

防音壁を構成するＦＲＰ壁材１、吸音体２いずれも軽量である。このため、防音壁も軽量となる。
このため、既存壁の置き換えにおいて、従来のコンクリート製の防音壁では高重量による下部の構造体への負荷が大きく、使用が困難な場合であっても、軽量な本発明の防音壁を使用できる。 Both the FRP wall material 1 and the sound absorbing body 2 constituting the soundproof wall are lightweight. Therefore, the soundproof wall is also lightweight.
Therefore, in the replacement of the existing wall, the conventional concrete soundproof wall can use the lightweight soundproof wall of the present invention even when it is difficult to use the heavy load on the lower structure due to its high weight. ..
