Further, the support column 3 is attached by using the anchor 5 to which the sound absorbing panel 1 is attached by inserting the flange portion 31 of the support column 3 having a U-shaped cross section into the screw portion 51.

図３は、図１における吸遮音パネル２Ａ及び２Ｂ全体を示す斜視図である。吸遮音パネル２は前面にパンチング孔が穿設され吸遮音性能を備えたパネル本体２１と、パネル本体２１の両側端にリベット止め等により固着して取り付けられた断面Ｌ字型の取付金具２２とを備えたもので、取付金具２２には、パネルの長手方向に長孔となされ、支柱３への取り付けを行うボルト孔２３が穿設されている。取付金具２２は、パネル本体２１の上下方向の全体に連続して設けられ、支柱３への取り付け後に隙間が生じて遮音性が損なわれるのを防止している。   FIG. 3 is a perspective view showing the entire sound absorbing and insulating panels 2A and 2B in FIG. The sound absorbing and insulating panel 2 includes a panel main body 21 having punching holes formed in the front surface and provided with sound absorbing and insulating performance, and an L-shaped mounting bracket 22 attached to both side ends of the panel main body 21 by rivets or the like. The mounting bracket 22 is formed with a long hole in the longitudinal direction of the panel, and a bolt hole 23 for mounting to the support column 3 is drilled. The mounting bracket 22 is provided continuously in the entire vertical direction of the panel main body 21, and prevents the sound insulation from being impaired due to the formation of a gap after the mounting to the column 3.

図４は、図１におけるＢ−Ｂ断面で、吸遮音パネル２の支柱３への取り付け状態の詳細を示す断面図である。吸遮音パネル２Ａのパネル本体２１は、両側端に設けられた側枠体２４と、側枠体２４にはリベット止め等により固着された、前面のパンチング板２５及び背面の背面板２６が取り付けられ、パンチング板２５と背面板２６との間に配置された吸音材２７とを備えたもので、パンチング板２５と吸音材２７とによって吸音性が具備され、背面板２６により遮音性が具備されるようになされている。隣接する吸遮音パネル２Ａの、取付金具２２のボルト孔２３が重ね合わされると共に、背面側から両方の取付金具２２のボルト孔２３に取付ボルトＢ１が挿通され、更に取付ボルトＢ１が支柱３のフランジ部３１に挿通されて、緩み止めのナットＮ１と締め付け用のナットＮ２とが螺着されて、支柱３に吸遮音パネル２が取り付けられる。   FIG. 4 is a cross-sectional view showing details of a state in which the sound-absorbing and insulating panel 2 is attached to the column 3 in the BB cross section in FIG. 1. The panel main body 21 of the sound absorbing and insulating panel 2A is provided with a side frame 24 provided at both ends, and a front punching plate 25 and a rear back plate 26 fixed to the side frame 24 by riveting or the like. The sound absorbing material 27 is disposed between the punching plate 25 and the back plate 26. The sound absorbing property is provided by the punching plate 25 and the sound absorbing material 27, and the sound insulating property is provided by the back plate 26. It is made like that. The bolt holes 23 of the mounting bracket 22 of the adjacent sound absorbing and insulating panel 2A are overlapped, the mounting bolt B1 is inserted into the bolt holes 23 of both mounting brackets 22 from the back side, and the mounting bolt B1 is further connected to the flange of the column 3 The nut 31 for locking and the nut N2 for tightening are screwed through the portion 31 and the sound absorbing and insulating panel 2 is attached to the column 3.

屈曲部３２に取り付けられる吸遮音パネル２Ｂについても、上述の直立部３１に取り付けられる吸遮音パネル２Ａと同様に支柱３に対して取り付けられる。尚、吸遮音パネル２Ａと吸遮音パネル２Ｂとの上下方向は、角部付近が突き合わせとされることで、その部分からの音漏れを防止するようになされている。   The sound absorbing and insulating panel 2B attached to the bent portion 32 is also attached to the support column 3 in the same manner as the sound absorbing and insulating panel 2A attached to the upright portion 31 described above. Note that, in the vertical direction of the sound absorbing and insulating panel 2A and the sound absorbing and insulating panel 2B, the vicinity of the corner portion is abutted to prevent sound leakage from that portion.

吸音パネル１及び吸遮音パネル２については、特に限定されるものではなく擁壁の前面４や支柱３に取り付け可能であれば用いることができる。吸遮音パネル２については、支柱３及びアンカー５に重量的な負担を増加させるものであるから、遮音性能が確保できる範囲で軽量なものとするのが好ましく、側枠体２４やその他の枠体、パンチング板２５等、遮音性への影響の小さい部分について軽量なアルミニウムやその合金を用いて形成したものが好適である。   The sound absorbing panel 1 and the sound absorbing and insulating panel 2 are not particularly limited, and can be used as long as they can be attached to the front surface 4 or the support column 3 of the retaining wall. The sound absorbing and insulating panel 2 increases the weight burden on the support columns 3 and the anchors 5, and is therefore preferably lightweight so long as sound insulation performance can be secured. The side frame body 24 and other frame bodies For example, the punching plate 25 and the like, which have a small influence on the sound insulation, are formed using lightweight aluminum or an alloy thereof.

支柱３についても、形成に用いる材料及び形状は特に限定されず、他に断面Ｈ型、断面Ｔ字型等の形状といった断面二次モーメントが高められた形状のものを好適に用いることができる。また材料については、アンカー５に重量的な負担を増加させるものであるから、アルミニウムやその合金を用いて形成したものを好適に用いることができる。また直立部３１に対する屈曲部３２の形状についても直角に限定されず、更に直立に近い角度や斜め４５度程度としたり、屈曲部３２全体若しくは一部に曲率（Ｒ）を持たせたものとしてもよい。   The material and shape used for the formation of the support column 3 are not particularly limited, and those having a shape with an increased second-order moment such as a cross-sectional H shape, a cross-sectional T shape, and the like can be suitably used. Moreover, about a material, since it raises a heavy burden to the anchor 5, what was formed using aluminum and its alloy can be used suitably. Further, the shape of the bent portion 32 with respect to the upright portion 31 is not limited to a right angle, and may be an angle close to an upright or about 45 degrees obliquely, or the entire bent portion 32 or a part thereof may have a curvature (R). Good.

尚、新設の防音壁の場合には、予め支柱３及び吸遮音パネル２の取り付けを見込んで大きい荷重に耐えうるアンカー５を埋設しておき、嵩上げが必要となった場合のみに支柱３及び吸遮音パネル２を取り付けるようにしてもよい。   In the case of a new soundproof wall, an anchor 5 that can withstand a large load is embedded in advance in anticipation of the mounting of the column 3 and the sound absorbing and insulating panel 2, and only when the column 3 and the column need to be raised. The sound insulation panel 2 may be attached.

また、本発明に係わる防音壁は、擁壁Ｙの前面４に対して取り付けられた既設の防音壁に対しても適用が可能である。図５はその一例を示すもので、（ａ）は適用される防音壁を示す斜視図、（ｂ）及び（ｃ）は支柱の取り付けを示す断面図である。（ａ）において、図１に示した吸音パネル１と同様に、吸音パネル１が取付金具１１を用いて擁壁Ｙの前面に取り付けられている。かかる防音壁において、設置当初は十分な防音性を備えていたものの、周囲の環境の変化により防音性が不足したり、設計時点で想定していた防音性が得られていなかったりする場合には、防音壁の嵩上げを行い防音性の向上を図る必要が生じてくる。   The soundproof wall according to the present invention can also be applied to an existing soundproof wall attached to the front surface 4 of the retaining wall Y. FIG. 5 shows an example thereof, (a) is a perspective view showing a soundproof wall to be applied, and (b) and (c) are cross-sectional views showing attachment of a column. In (a), similarly to the sound absorbing panel 1 shown in FIG. 1, the sound absorbing panel 1 is attached to the front surface of the retaining wall Y using the mounting bracket 11. In the case of such a sound barrier, although it had sufficient soundproofing properties at the beginning of installation, the soundproofing properties were insufficient due to changes in the surrounding environment, or the soundproofing properties that were assumed at the time of design were not obtained. Therefore, it is necessary to raise the soundproof wall to improve the soundproofing property.

かかる状況において、上述の実施形態に示した如く支柱３及び吸遮音パネル２による嵩上げを行うことができる。まず（ｂ）において、吸音パネル１を固定する緩み止めのナットＮ１と締め付け用のナットＮ２とを工具を用いて取り外す。吸音パネル１は他方の取付金具１１により固定されているが、前面側を押さえる等して固定しておくのが好ましい。次に（ｃ）に示す如く、支柱３のフランジ部３１に穿設されたボルト孔３２をアンカー５のねじ部５１に挿通させ、挿通後に再度ナットＮ１及びＮ２を螺着する。かかる方法によって、支柱３を極めて簡便に擁壁Ｙに取り付け、防音壁の嵩上げを行うことが可能となる。   In such a situation, as shown in the above-described embodiment, the uplift by the support column 3 and the sound absorbing and insulating panel 2 can be performed. First, in (b), the locking nut N1 and the fastening nut N2 for fixing the sound absorbing panel 1 are removed using a tool. Although the sound absorbing panel 1 is fixed by the other mounting bracket 11, it is preferable to fix it by pressing the front side. Next, as shown in (c), the bolt hole 32 drilled in the flange portion 31 of the support column 3 is inserted into the screw portion 51 of the anchor 5, and the nuts N1 and N2 are screwed again after the insertion. By such a method, it becomes possible to attach the support column 3 to the retaining wall Y very simply and raise the soundproof wall.
