Description
【0001】
【発明の属する技術分野】
本発明は、自動車や鉄道車両等の通行帯における防音壁の施工方法に関する。
【0002】
【従来の技術】
従来、車両等が通行する道路や鉄道では、車両の通行に伴い騒音が発生する。この騒音防止対策として防音壁が設けられている。その防音壁としては、通行帯の端に防音プレートを並べ立設したもの、吸音材を壁体に直接取付けたもの等があり、防音プレートはH鋼を一定間隔に立て、そのH鋼間に防音プレートを差し込んで取付けられるのが殆どである。そして防音プレート自体も表面を凹凸にしたコンクリート製のものや金属製のものである。又、吸音材についても単に表面を凹凸にしたコンクリート製あるいは金属製のもの、あるいは中が中空に加工した金属製のもの等であった。
【0003】
【発明が解決しようとする課題】
上記従来の防音壁において、防音プレートの場合に騒音を外部に遮音する効果は大きいが、かなりの騒音が通行帯内に反射し運転者及び乗客に不快感を生じさせ、必ずしも満足すべきものでなかった。他方、吸音板は、単に表面を凹凸にしただけのものでは吸音効果が少なく、中空状に加工した金属製のものでは吸音効果が大きいがコスト的に高価であり、大量の使用を伴う防音壁では施工がコスト高となる等の問題点を有していた。
【0004】
本発明の目的は、低コストで防音効果の高い防音プレートを使用し、その防音プレートの取付け方により、より防音効果を高めた車両通行帯における防音壁の施工方法を提供することにある。
【0005】
本発明の他の目的は、施工性が極めて簡単な車両通行帯における防音壁の施工方法を提供することにある。
【0006】
【課題を解決するための手段】
この目的を達成するために本発明は、車両通行帯(A)の端で予め構築した壁体(1)に、少なくとも多数の貫通穴(2a)を穿設した防音プレート本体(2)を前記壁体(1)から一定間隔離して順次多数枚取付けると共に、前記防音プレート本体(2)が、前記貫通穴( 2a )に挿入した取付具(5)で前記壁体(1)に取付ける。そして前記貫通穴(2a)の断面形状が前記防音プレート本体(2)の表側(2b)を大きく裏側(2c)を小さくし、その表側(2b)を前記車両通行帯(A)側に向け前記防音プレート本体(2)を取付ける。
【0007】
また、前記防音プレート本体(2)が、前記隙間(3)内に入れた吸音材(4)を介して前記壁体(1)に取付けるのが好ましい。
【0008】
また、前記防音プレート本体(2)が、コンクリート製,プラスチック製,金属製,ゴム製,アスファルト製等である。
【0009】
また、前記貫通穴(2a)が、その断面形状を略ラッパ状とするのが好ましい。
【0010】
壁体(1)は、車両通行帯(A)の端に既に構築されている側壁,トンネル内の壁,擁壁等であり、壁体(1)がない箇所では予めコンクリートや金属製のパネルで車両通行帯(A)の端に壁体(1)を構築させている。
【0011】
防音プレート本体(2)は、多数の貫通穴(2a)を穿設したものであり、材質としては、コンクリート,プラスチック,金属,ゴム等,アスファルト製である。特にコンクリート製では、プレキャストコンクリート製であり、内部に補強用の金網が入っている。又、コンクリート製,ゴム製,アスファルト製においては、通気性のあるポーラス状に形成させると、防音プレート本体(2)の全体が材質の面で吸音性を増し、より防音効果を高める。
【0012】
【発明の実施の形態】
以下、本発明の実施に形態につき、図を基に説明する。図1は本発明の施工方法を示す説明図、図2は本発明の施工方法で吸音材を加えた説明図、図3は本発明の施工状態の正面図、図4は本発明の防音プレートの一部断面図である。
【0013】
図1及び図2において、(1)は壁体であり、車両通行帯(A)の端に予め構築されている。この壁体(1)としては、殆どがコンクリート製であり一部金属製の場合もある。そしてこの壁体(1)の種類としては、側壁,トンネル壁,擁壁等のものである。又、これらの壁体(1)がない車両通行帯(A)の箇所においては、コンクリート製あるいは金属製のパネルでもって、予め壁体(1)を構築しておけばよい。
【0014】
この壁体(1)に対し、図1では多数の貫通穴(2a)を穿設した防音プレート本体(2)を壁体(1)から一定間隔離して多数枚を順次取付け、壁体(1)と防音プレート本体(2)の間に隙間(3)を設けた施工方法である。この方法では騒音の遮音効果が高い。
【0015】
図2では防音プレート本体(2)は隙間(3)に入れた吸音材(4)を介して壁体(1)に取付けた施工方法であり、騒音の遮音及び吸音効果の面で有効である。
【0016】
吸音材(4)は、隙間(3)の範囲内に入る厚さのもので、材料としては例えばグラスウール,発泡ゴム等が使用される。この吸音材(4)は、先に壁体(1)に接着材等で取付けて置き、その後に防音プレート本体(2)を壁体(1)に取付けるとよい。この吸音材(4)は、隙間(3)いっぱいの厚さよりも多少その隙間(3)よりも薄いものを使用する方が多少の隙間(3)を残すため、貫通穴(2a)から騒音が通過し易く防音効果が高い。
【0017】
次に防音プレート本体(2)の取付けに使用する取付具(5)について説明すると、取付具(5)は壁体(1)に穴を開け埋設させたアンカープラグ(5a),セパレーター(5b),ボルト(5c)とから少なくとも成るものであり、一枚の防音プレート本体(2)の少なくとも4隅の貫通穴(2a)を利用し(図3参照)、その貫通穴(2a)にボルト(5c)を挿入しアンカープラグ(5a)に螺合させ締付けて防音プレート本体(2)を壁体(1)に取付ける。この際に壁体(1)と防音プレート本体(2)との間に筒状のセパレーター(5b)がボルト(5c)を挿通して装着されており、このセパレーター(5b)により、壁体(1)と防音プレート本体(2)との間に一定の隙間(3)が保持される。
【0018】
また、防音プレート本体(2)は、その貫通穴(2a)の断面形状が図4で示すように略ラッパ状で表側(2 b)を大きくし、裏側(2c)を小さくしている。つまり、貫通穴(2a)は、防音プレート本体(2)の表側(2b)が大きく開け、裏側(2c)では小さく開けている。そして、防音プレート本体(2)の取付けは、表側(2b)を車両通行帯(A)側に向けて取付けられる。つまり裏側(2c)が壁体(1)と対面するように取付けられる。尚、貫通穴(2a)の断面形状としては上記略ラッパ状の外に、テーパー状あるいは段付きとしてもよい。
【0019】
【発明の効果】
本発明は上記説明したように、多数の貫通穴(2a)を穿設した防音プレート本体(2)を使用し、壁体(1)から一定間隔離し隙間(3)を設けて取付けたことにより、車両通行帯(A)を通行する車両からの騒音は防音プレート本体(2)に当り、騒音の多くは多数の貫通穴(2a)から壁体(1)と防音プレート本体(2)との隙間(3)に入り込み、隙間(3)の上方から逃げるため、防音性が高い。
【0020】
また、防音プレート本体(2)の貫通穴(2a)は、表側(2b)が大きく、裏側(2c)を小さくし、その表側(2b)を車両通行帯(A)に向けて取付けているため、騒音は表側(2b)の大きい貫通穴(2a)で乱反射し互いに打消し合って消音効果を発揮し、且つ、貫通穴(2a)の表側(2
b)入口が大きいので騒音の集音性も高く、集音された騒音が防音プレート本体(2)を通過し易く、より多くの騒音が隙間(3)に入り込み防音性を高める。
【0021】
更に、防音プレート本体(2)は、その貫通穴(2a)をそのまま利用して壁体(1)に取付けできるので、現場で防音プレート本体(2)には何の加工も必要なく、取付作業が簡単で施工コストも安価にできる。又、貫通穴(2a)は表側(2b)が大きい穴のため、取付けの際にボルト(5c)の頭あるいはナット等が貫通穴(2a)内に入り込み、表側(2b)に出ないのできれいに施工できる。
【0022】
また、隙間(3)に吸音材(4)を入れて施工したものは、隙間(3)内に入った騒音が吸音材(4)で吸音され、外部に出ないため、より防音性を発揮し、トンネル内や地下道の車両通行帯(A)内の防音として極めて有効となる。

[Problems to be solved by the invention]
In the case of the above-mentioned conventional soundproof wall, in the case of the soundproof plate, the effect of insulating the noise to the outside is great, but considerable noise is reflected in the traffic zone, causing discomfort to the driver and passengers, which is not necessarily satisfactory. It was. On the other hand, the sound-absorbing plate has a small sound-absorbing effect when the surface is simply uneven, and the metal-made one processed into a hollow shape has a large sound-absorbing effect but is expensive in terms of cost, and requires a large amount of use. However, there were problems such as high construction costs.

[ 0013 ]
In FIG.1 and FIG.2, (1) is a wall body and is constructed | assembled beforehand at the edge of a vehicle traffic zone (A). The wall (1) is mostly made of concrete and may be partially made of metal. And as a kind of this wall (1), it is a thing of a side wall, a tunnel wall, a retaining wall, etc. Further, at the location of the vehicle traffic zone (A) where these wall bodies (1) are not present, the wall body (1) may be constructed in advance with a concrete or metal panel.
[ 0014 ]
In FIG. 1, the soundproof plate body (2) having a large number of through holes (2a) is attached to the wall body (1) by separating the wall body (1) from the wall body (1) at a predetermined interval, and a large number of sheets are sequentially attached. ) And a soundproof plate body (2). This method has a high noise insulation effect.
[ 0015 ]
In FIG. 2, the soundproof plate body (2) is a construction method in which the soundproof plate body (2) is attached to the wall (1) through the sound absorbing material (4) placed in the gap (3), and is effective in terms of noise insulation and sound absorption effect. .
[ 0016 ]
The sound absorbing material (4) has a thickness that falls within the range of the gap (3), and for example, glass wool, foam rubber, or the like is used as the material. The sound absorbing material (4) is preferably attached to the wall body (1) with an adhesive or the like first, and then the soundproof plate body (2) is attached to the wall body (1). This sound-absorbing material (4) is slightly thinner than the gap (3) full thickness, leaving a little gap (3), so there is noise from the through hole (2a). Easy to pass and high soundproofing effect.
[ 0017 ]
Next, the fixture (5) used to mount the soundproof plate body (2) will be described. The fixture (5) is an anchor plug (5a) and a separator (5b) that are embedded in the wall (1). , Bolts (5c), and at least four corners of the through holes (2a) of the soundproof plate body (2) are used (see FIG. 3), and bolts ( 5c) is inserted, screwed into the anchor plug (5a) and tightened to attach the soundproof plate body (2) to the wall body (1). At this time, a cylindrical separator (5b) is inserted between the wall (1) and the soundproof plate body (2) by inserting a bolt (5c), and the separator (5b) A constant gap (3) is maintained between 1) and the soundproof plate body (2).
[ 0018 ]
The soundproof plate body (2) has a through-hole (2a) with a substantially trumpet cross-sectional shape as shown in FIG. 4, with the front side (2b) enlarged and the back side (2c) made smaller. That is, the through hole (2a) has a large opening on the front side (2b) of the soundproof plate body (2) and a small opening on the back side (2c). The soundproof plate body (2) is attached with the front side (2b) facing the vehicle lane (A). That is, it attaches so that a back side (2c) may face a wall body (1). The cross-sectional shape of the through hole (2a) may be tapered or stepped in addition to the substantially trumpet shape.
[ 0019 ]
【The invention's effect】
As described above, the present invention uses the soundproof plate body (2) having a large number of through holes (2a), and is separated from the wall body (1) by a certain distance and provided with a gap (3). The noise from the vehicle passing through the vehicle lane (A) hits the soundproof plate main body (2), and most of the noise is generated between the wall body (1) and the soundproof plate main body (2) from the many through holes (2a). Since it enters the gap (3) and escapes from above the gap (3), the soundproofing property is high.
[ 0020 ]
Moreover, the through hole (2a) of the soundproof plate body (2) has a large front side (2b), a small back side (2c), and the front side (2b) is mounted facing the vehicle lane (A). , Noise is diffusely reflected in the large through hole (2a) on the front side (2b) and cancels each other out to produce a silencing effect, and the front side of the through hole (2a) (2
b) Since the entrance is large, the sound collecting property is high, and the collected noise easily passes through the soundproof plate body (2), so that more noise enters the gap (3) and the soundproofing property is improved.
[ 0021 ]
Furthermore, since the soundproof plate body (2) can be attached to the wall body (1) using the through hole (2a) as it is, there is no need to process the soundproof plate body (2) on site, and the installation work However, the construction cost can be reduced. Also, the through hole (2a) has a large front side (2b), so the head or nut of the bolt (5c) enters the through hole (2a) and does not come out to the front side (2b) when installing. Can be constructed.
[ 0022 ]
In addition, when the sound absorbing material (4) is put in the gap (3), the noise that enters the gap (3) is absorbed by the sound absorbing material (4) and does not go outside, so it is more soundproof. However, it is extremely effective as soundproofing in the tunnel and the vehicle traffic zone (A) in the underpass.
