【００１１】
【発明の実施の形態及び実施例】
図１と図２は、請求項１に記載した発明に係る市街地用の透光板付き低層遮音壁の実施形態を示している。
これは図２で明らかなように市街地の車道と歩道の境界部位に設置されるもので、長手方向に隣接するＨ形支柱１、１間の溝内の下部に吸音壁パネル２が支持され、該吸音壁パネル２の上に積み重ねて立てた透光板３がやはりＨ形支柱１の溝内に支持されている。Ｈ形支柱１は、地面下に設けたコンクリート基礎ブロック５に固定して立てられている。吸音壁パネル３の上面部に、図２と図６に詳細を示したように上向きに開口する受け溝７を有する化粧板６を取り付け、前記受け溝７へ透光板３の下端部を嵌め込んで立てている。金属製の吸音壁パネル２と、合成樹脂製の透光板３との熱膨張差を吸収するためである。
【００１２】
吸音壁パネル２の構造は、図２に概要を示したように、薄い金属製板材で形成したケーシングの前面（車道側の面）に多数の吸音開口が設けられ、同ケーシングの内部に吸音材２ａが配置された構成である。透光板３には、例えば透明な合成樹脂板（ポリカーボネート板）が使用されている。
前記Ｈ形支柱１は、前記透光板３の支持に必要な限度の地面上高さＨに制限して、無骨な存在感をできるだけ希釈した構成とされている。Ｈ形支柱１より上方部分では、隣接する透光板３、３同士の端縁が、やはり透明なポリカーボネート製のジョイント部材４で相互に拘束され、風圧や地震などに対する構造的安定性を保つ構成とされている。
【００１３】
吸音壁パネル２の背高は、歩道を歩く普通の背丈の人の視界（及び自動車の運転者の視界）をあまり遮らないように、目線よりもかなり低い地面上約８００ｍｍ程度とし、同歩行者の目線の範囲は透光板３で遮蔽するように透光板３の背高を約７００ｍｍ程度とし、もってこの低層遮音壁の全高は地面上１５００ｍｍ程度の高さに構成されている（請求項２記載の発明）。因みに前記Ｈ形支柱１の地面上の高さＨは１１００ｍｍ位とし、もって前記透光板３の下部は、Ｈ形支柱１の上部約３００ｍｍ程度の高さｈで支持されている。
【００１４】
上述した市街地用の透光板付き低層遮音壁を構築するにあたっての重大な問題点は、前記構造の吸音壁パネル２の重量がおよそ４０〜５０ｋｇにもなり、これをＨ形支柱１の上端から溝内へ建て込む（嵌め込む）方法を採用すると、複数人が共同しても人手による作業は至難と云うのほかなく、小型の重機類を使用して吊り込む作業になるから、重機の確保と使用コストが負担になる。
【００１５】
そこで本発明では、人手による作業、それも比較的に軽労働の作業で構築を行えるように、吸音壁パネル２は、地面上に立てた姿勢のまま水平横方向へ動かす操作で立て込む方法・構成が採用される。
その手段として、先ず吸音壁パネル２の長さ（通例２０００ｍｍ）に対して、長手方向に隣接するＨ形支柱１、１は、そのフランジ間の内法寸法Ｌを例えば１０ｍｍ程度大きい配置間隔で立てる。そして、吸音壁パネル２は、地面上に立てた姿勢のまま水平横方向へ移動させて隣接するＨ形支柱１、１の間へ配置する。この程度の作業は、通常の大人が２人も共同すれば何の苦もなくできる。
【００１６】
しかる上で、図３及び図４に示したように、Ｈ形支柱１の溝１ｃ内へ別途嵌め込んだ係止部材８を当該吸音壁パネル２の両端へ付設して支持させる（請求項３記載の発明）。
図４で明らかなように、係止部材８にはＨ形支柱１の溝１ｃの幅（８４ｍｍ）よりも少し小さい幅（７５ｍｍ）の溝形鋼材が好適に使用される。該溝形鋼材８の下部は、図３と図５に示したように横繋ぎ材１０の端部を利用して吸音壁パネル２の側面下部に固定された上向きのフック形部材１１へ、上方から下ろしつつウエブ８ｄの内面を掛け止めて拘束されている（図５、及び図８と図９も参照）。吸音壁パネル２は、その下面の前記横繋ぎ材１０をＨ形支柱１の下端部のベースプレート９上に載置される。
【００１７】
他方、同じ溝形鋼材８の上部は、吸音壁パネル２の上面部および溝形鋼材上面部へボルト１２と１３で止めた調整板１４により、同溝形鋼材８の一側面をＨ形支柱１の一方のフランジ内面１ａへ当接させ、他方のフランジ内面１ｂには調整板１４の外縁を当接させた状態の位置決め固定が行われる（請求項４記載の発明）。
【００１８】
そのため調整板１４は直角に曲がった形状とされ（図４）、その脚部１４ａは長手方向の長孔状に設けられたボルト孔１５を通じて吸音壁パネル内側のナット１６へねじ込んだ少なくとも２本のボルト１２、１２により長手方向への出入り量を調整した上で固定される。直角な頭部１４ｂは、直角方向に長孔状とされたボルト孔１５を通じて溝形鋼材８の上端板８ｃへ溶接したナット１７へねじ込んだ少なくとも２本のボルト１３、１３により溝幅方向への調整を行い、即ち溝形鋼材８の一側面８ａを一方のフランジ内面１ａへ当接させ、逆に前記頭部１４ｂの外縁を他方のフランジ内面１ｂへ当接させた状態で固定される（図４及び図９）。したがって、吸音壁パネル２がＨ形支柱１の溝内でガタつくことは確実に防止される。
【００１９】
ところで、係止部材たる溝形鋼材８の下部の幅寄せ手段に関しても、次のような幅寄せ機構が設けられている。
先ず図８〜図１０は、Ｈ形支柱１の溝内に沿って図８の矢印のように下ろす溝形鋼材８の下部は、吸音壁パネル２の側面下部に固定された上向きのフック形部材１１で拘束されることを示している。と同時に、図８と図９は、前記のフック形部材１１の水平な上縁へ当接するように、下面１８ａを傾斜面に形成して溝形鋼材８の下部に設けられた傾斜ブロック１８と、前記傾斜ブロック１８とは一体をなす構造で、溝形鋼材８の一方の側面８ｂ及びこれと相対峙するＨ形支柱１の一方のフランジ内面１ｂとの間に位置する梃子部材１９とで構成された幅寄せ機構により、当該溝形鋼材８の他側の側面８ａの下部をＨ形支柱１の他方のフランジ内面１ａと接触させるように幅寄せして位置決め固定が行われること（請求項５記載の発明）を示している。
【００２０】
即ち、前記梃子部材１９は、図８のように垂直な姿勢で溝形鋼材８と共に下降される。そして、傾斜ブロック１８の傾斜した下面１８ａがフック形部材１１の水平な上縁の上に載ると、同下面１８ａの傾きに従って傾斜ブロック１８が傾動し、ひいては梃子部材１９が絶対的固定のＨ形支柱１のフランジ内面１ａを支点として傾き、可動な溝形鋼材８の側面８ａを所謂梃子の作用で押し、もって溝形鋼材８の他側の側面８ａの下部をＨ形支柱１の他方のフランジ内面１ａへ当接させる幅寄せ作用を行うのである。
【００２１】
図示例では傾斜ブロック１８の下面１８ａが傾斜面に形成されているが、逆に、フック形部材１１の上縁を傾斜させても良い。梃子部材１９は、その腕部が溝形鋼材８の側面８ｂに設けたルーズ孔（又は切り欠き）へ傾動可能に通され、同腕部と傾斜ブロック１８とがボルト２０により一体的に結合されている。
次に、図１１と図１２には異なる幅寄せ機構の実施例を示した。本実施例の場合も溝形鋼材８の下部が、やはり吸音壁パネル２の側面下部に固定された上向きのフック形部材１１で拘束される。フック形部材１１の両側縁が上向きに幅が狭まる傾斜のガイド側縁１１ａに形成され、このガイド側縁１１ａへ当接して滑るように溝形鋼材８の下部に設けた傾動部材２１、及び傾動部材２１の背面バー２２がＨ形支柱１の一方のフランジ内面１ａへ当接する構成の幅寄せ機構が設けられている。この幅寄せ機構により、溝形鋼材８の他側の側面８ｂの下部をＨ形支柱１の他方のフランジ内面１ｂへ当接させるまで幅寄せして位置決め固定が行われる（請求項６記載の発明）。
【００２２】
なお、図１１、図１２の実施例は、傾動部材２１がヒンジ２３の一方のヒンジ板で形成され、他方のヒンジ板を溝形鋼材８の側面下部へ固定した構成であるが、この限りではない。溝形鋼材８をＨ形支柱１の溝内へ下ろしてゆくと、吸音壁パネル２の側面下部に固定された上向きのフック形部材１１のガイド側縁１１ａへ当接して滑り、その背面部がフランジ内面に当たって溝形鋼材８の下部を押して幅寄せ作用を奏する構成であれば、例えば可撓性を有する１枚の板による構造、その他の構成でも良い。
【００２３】
次に、透光板３のＨ形支柱１の溝に対する取付け手段について説明する。
先の図６と図７に示した実施例は、アングル材２４を用いて透光板３をＨ形支柱１の溝内の一方へ片寄せした位置に支持させる例である。即ち、透光板３の片面は、Ｈ形支柱１の一方のフランジ内面へパッキン２７を間に挟んで当接される。同透光板３の他面は、やはり間にパッキン２７を挟んでアングル材２４の一面で支持させると共に、Ｈ形支柱１のウエブへ通したボルト２５とナット２６で同アングル材２４の他面を締め付け固定して取付けが行われている（請求項７記載の発明）。アングル材２４には、図６に示したように、ボルト２５による固定位置の調整が可能であるように、水平横方向に長いボルト孔２８が設けられている。
【００２４】
次に、図１３と図１４には異なる取付け手段の実施例を示した。本実施例は押さえ縁部材として使用する溝形材３０とサッシュ材３１とにより透光板３をＨ形支柱１の溝内のほぼ中央位置へ支持させる例である。即ち、透光板３の片面は、Ｈ形支柱１の溝内に、その一方のフランジ内面１ａに沿って配置しカシメピン３７で固定したサッシュ材３１へ、間にパッキン２７を挟んで当接されている。同透光板３の他面は、同じＨ形支柱１の他側のフランジ内面１ｂとウエブにかけてほぼ水平に溶接で固定した上下の固定板３２、３２の間へ、溝形材３０を配置して支持されている。当該溝形材３０は、その上下の端部を、前記した固定板３２のボルト孔３３へ通したボルト３４によって締め付け固定されている（請求項８記載の発明）。
【００２５】
溝形材３０の上下の端部には水平な端板３０ａが固定され、同端板３０ａの内側面に前記のボルト３４をねじ込むナット３５が固定されている。一方、前記固定板３２のボルト孔３３は、溝形材３０で透光板３を押す方向に長い長孔として設けられ、透光板の支持力及び支持位置の調整が可能とされている。
なお、図中の符号４０はＨ形支柱１の外面を覆う形に取り付けた化粧板、４１はＨ形支柱１の溝開口を塞ぐように取付けた化粧板である。
【００２６】
【本発明が奏する効果】
請求項１〜８記載の発明に係る市街地用の透光板付き低層遮音壁は、車道を走る自動車の騒音を低減する吸音、遮音機能を発揮することは当然のこと、歩道を歩く人及び自動車の運転者の視界をあまり遮らないから、市街地の景観を乱さず、人及び環境に優しい構造である。
【００２７】
しかも、この透光板付き低層遮音壁は、設置施工に重機類を必要とせず、人力でも比較的軽労働の内容で容易、且つ簡単、確実に構築できるのである。

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
1 and 2 show an embodiment of a low-rise sound insulation wall with a translucent plate for an urban area according to the invention described in claim 1.
As is apparent from FIG. 2, this is installed at the boundary between the roadway and sidewalk in the urban area, and the sound absorbing wall panel 2 is supported at the lower part in the groove between the H-shaped columns 1 and 1 adjacent in the longitudinal direction. A translucent plate 3 stacked on the sound absorbing wall panel 2 is also supported in the groove of the H-shaped support column 1. The H-shaped support column 1 is fixedly erected on a concrete foundation block 5 provided under the ground. As shown in detail in FIGS. 2 and 6, a decorative plate 6 having a receiving groove 7 that opens upward is attached to the upper surface of the sound absorbing wall panel 3, and the lower end portion of the translucent plate 3 is fitted into the receiving groove 7. Standing up. This is to absorb the thermal expansion difference between the metal sound absorbing wall panel 2 and the synthetic resin translucent plate 3.
[0012]
As outlined in FIG. 2, the structure of the sound absorbing wall panel 2 is provided with a number of sound absorbing openings on the front surface (surface on the roadway side) of a casing formed of a thin metal plate, and the sound absorbing material is provided inside the casing. 2a is arranged. For the translucent plate 3, for example, a transparent synthetic resin plate (polycarbonate plate) is used.
The H-shaped support column 1 is configured so as to dilute a rugged presence as much as possible by limiting the height H above the ground level necessary for supporting the light-transmitting plate 3. In the upper part from the H-shaped support column 1, the edges of the adjacent translucent plates 3 and 3 are mutually restrained by a joint member 4 made of transparent polycarbonate, and the structural stability against wind pressure and earthquake is maintained. It is said that.
[0013]
The height of the sound-absorbing wall panel 2 is about 800 mm on the ground, which is considerably lower than the line of sight, so as not to obstruct the view of ordinary people walking on the sidewalk (and the view of the driver of the car) so much. The height of the light transmission plate 3 is set to about 700 mm so that the light transmission plate 3 is shielded by the light transmission plate 3, and the total height of the low-layer sound insulation wall is about 1500 mm above the ground. Described invention). Incidentally, the height H of the H-shaped column 1 on the ground is set to about 1100 mm, and the lower part of the translucent plate 3 is supported at a height h of about 300 mm above the H-shaped column 1.
[0014]
The serious problem in constructing the above-mentioned low-rise sound insulation wall with a translucent plate for an urban area is that the weight of the sound absorbing wall panel 2 having the above structure is approximately 40 to 50 kg, which is inserted into the groove from the upper end of the H-shaped support column 1. By adopting the built-in (inserting) method, it is difficult to work manually even when multiple people work together. Usage costs are a burden.
[0015]
Therefore, in the present invention, the sound absorbing wall panel 2 is stowed by an operation of moving the sound absorbing wall panel 2 in the horizontal and lateral directions while being placed on the ground so that it can be constructed by manual work or relatively light labor work. Configuration is adopted.
As the means, first, the H-shaped support columns 1 and 1 adjacent in the longitudinal direction with respect to the length of the sound-absorbing wall panel 2 (usually 2000 mm) set the inner dimension L between the flanges at an arrangement interval larger by, for example, about 10 mm. .
