Description

【0001】
【発明の属する技術分野】
本発明は、主として中央分離帯等に設置される防音壁に関するものである。
【0002】
【従来の技術】
例えば中央分離帯等に設置される防音壁として、道路に沿って適宜間隔をあけて立設したH型鋼からなる支柱の上端間にボックスビームを固定し、そのボックスビームの下部空間に前記支柱を利用して防音板が取付けられたものがある。この防音壁は、前記ボックスビームにより車両に対する防護効果を具備させると共に、車両の騒音を防音板により抑制することにより防音効果をも具備させたものである。
【0003】
従来、かかる防音壁における防音板の取付構造としては、防音板の左右の端面にH型鋼からなる支柱のフランジが入り込む凹部を予め形成し、この防音板を支柱の高さ以上に持ち上げ、左右の凹部をフランジにはめ合わせて上から隣接支柱間に落とし込むことにより、防音板を支柱に取付けるようにしたものがある。
【0004】
【発明が解決しようとする課題】
しかしながら防音板を支柱の高さ以上に持ち上げて上から隣接支柱間に落とし込んで取付ける構造では、防音板が破損して別の防音板に取り替える際に、支柱の上端間にボックスビームが固定されている場合は、まずこのボックスビームを取り外し、しかる後に防音板の脱着を行う必要があり、又支柱の上端間に固定したボックスビームの下部空間に、前記支柱を利用して防音板を新規に取付ける場合においても、まずボックスビームを取り外し、しかる後に防音板を取付ける必要がある等、防音板の取付けが容易でなく、又工期が長くかかる等の問題がある。
【0005】
そこで支柱のフランジにボルト孔を開け、このボルト孔に防音板を直接ボルト止めすることにより、防音板を支柱にフランジの外側より取付けることができるようになされたものもあるが、支柱にボルト孔を開けることは強度が低下することから好ましくなく、又その加工工数が増える等の問題がある。
【0006】
そこで本発明は、上記の如き問題を解決し、支柱にボルト孔を開けることなく、且つ防音板を支柱にフランジの外側より取付けることができるようになされた防音壁を提供せんとするものである。
【0007】
【課題を解決するための手段】
上記目的を達成するために、本発明は次のような構成としている。
すなわちこの発明に係る防音壁は、外側面に相対向するフランジが上下方向に形成された支柱と、嵌合溝が上下方向に形成されると共に外面に取付ボルトが突設固定されたクリップ部材と、側端部に取付孔が穿設された防音板とを有し、支柱は隣り合う支柱のフランジを相対向させて、互いに間隔を隔てて道路や鉄道等に沿って立設され、クリップ部材は嵌合溝を支柱のフランジに嵌合させることにより支柱に取付けられ、防音板は取付孔を前記取付ボルトにはめ合わせてナット締めすることにより、クリップ部材を介して支柱に取付けられるようになされたことを特徴とするものである。
【0008】
本発明による防音板の取付方法は、まず、外側面に相対向するフランジが上下方向に形成された支柱を、隣り合う支柱のフランジを相対向させて、互いに間隔を隔てて道路や鉄道等に沿って立設する。そして外面に取付ボルトが突設固定されたクリップ部材の嵌合溝を前記フランジに相対向させると共に、その嵌合溝をフランジに嵌合させてクリップ部材を支柱に取付ける。次いで、防音板の取付孔をクリップ部材の取付ボルトにはめ合わせた後、取付ボルトにナットを締めつけて固定すればよい。
【0009】
従って本発明によれば、防音板を支柱の高さ以上に持ち上げる必要がなく、防音板を支柱にフランジの外側より取付けることができるので、又支柱の上端間にボックスビームが固定されていても、防音板を脱着する際にボックスビームを取り外す必要がないので、防音板の取付け取り外しが容易であり、施工性が良く、工期も短くなる。
【0010】
さらに本発明によれば、クリップ部材を介して防音板が支柱に取付けられ、防音板を取付けるために、支柱にボルト孔を開ける必要がないので、支柱の強度は低下せず、又ボルト孔を開けるための加工工数も必要ない。
【0011】
なお、クリップ部材の上部に掛止部を形成し、掛止部を支柱に掛止させることにより、クリップ部材を支柱に掛け止めることができるようにすれば、支柱に取付けられた状態においてクリップ部材の位置が安定し、位置決めが容易になると共に脱落を防止できるので、防音板の取付孔をクリップ部材の取付ボルトにはめ合わせる際の作業が容易となる。
【0012】
又、本発明において、防音板の側端部に張出部を形成し、該張出部に取付孔を穿設しておけば、防音板の取付孔をクリップ部材の取付ボルトにはめ合わせる際のはめ合わせが容易となり、又この張出部を前面側寄りに形成しておけば、支柱に取付けた防音板の納まりがよい。
【0013】
さらに、本発明において、防音板による車両の騒音を抑制する防音効果に加えて、車両に対する防護効果を具備させるために、支柱を利用してボックスビームが防音板の上部及び/又は下部に取付けられているのが好ましい。
【0014】
【発明の実施の形態】
次に、本発明の実施の形態について図面を参照し、具体的に説明する。
図1は本発明防音壁の実施の一形態を示す正面図、図2は図1の切欠側面図、図3は図1の断面図、図4は図1の分解斜視図、図5は図1で用いられたクリップ部材の斜視図である。
【0015】
図面において、1は支柱であり、断面がH型となされて外側面にフランジ11が前後に相対向して設けられ、隣り合う支柱1の前記フランジ11を相対向させて、互いに間隔を隔てて道路や鉄道等に沿って立設される。
【0016】
2はクリップ部材であり、前後の相対向する止め板部21間に前記支柱1のフランジ11に嵌合可能な嵌合溝22が上下方向に形成され、その一方の止め板部21の外面に取付ボルト3が突設固定され、さらに一方の止め板部21の上部が嵌合溝22側に折曲され、支柱1の上端に掛止可能な掛止部23が形成されているものである。このクリップ部材2は支柱1の前後のフランジ11にそれぞれ対応して対称形のものが二個用いられる。
【0017】
クリップ部材2の材料としては、一般には圧延鋼板を溶融亜鉛にどぶ漬けした材料が、加工性及び耐錆性、強度の点から好ましいが、特に限定されず、その他、ステンレス板、アルミニウム板、合成樹脂板等の適宜材料が用いられてもよい。またクリップ部材2は、プレス等により所定形状に形成した板状体を前後に折曲して形成されていてもよいし、別体で板状体により形成された二個の止め板部21を間隔を開けて相対向させ、その間隔を嵌合溝22としてそれらを溶接等により固着させて形成されていてもよい。クリップ部材2を圧延鋼板から形成する場合は、強度及び加工性を考慮すると厚み2〜10mm程度のものが好ましいが特に限定されるものではない。
【0018】
4は防音板であって、多数の開孔41を有する前面板42と無孔の遮音性を有する背面板43とからなる箱体44にガラスウール等の吸音材45が内装され、車両の騒音が前面板42の開孔41より箱体44内に入射され、吸音材45により減衰されると共に背面板43により遮音されるようになされた吸遮音タイプのものである。さらに防音板4は左右側端部に張出部46が形成され、その張出部46に前記クリップ部材2の取付ボルト3にはめ合わせ可能な取付孔47が穿設されている。この取付孔47は取付ボルト3との位置が多少ずれてもはめ合わせやすいように長孔とするのが好ましい。
【0019】
この防音板4は、中央分離帯に設置される場合は、それぞれの対向車線側からの騒音を抑制するために前後両側にそれぞれ配置されるが、片側のみに配置されてもよい。片側のみに配置する場合等は、前面板42と背面板43とは同一の材料から形成されていてもよいし、前面板42にコンクリート板を用い、背面板43に美観を高めるために化粧板を用いる等、前面板42と背面板43とは異なる材料から形成されていてもよい。
【0020】
さらに背面板43にも多数の開孔を設け、騒音が前面板42と背面板43の両方から箱体44内に入射されて吸音される吸音タイプであってもよく、又ポリカーボネートやアクリル樹脂等の透光性合成樹脂板やガラス等の透光板からなる面板が枠材により支持された透視性を備えた遮音タイプや金属や合成樹脂からなる不透明な面板からなる非透視性の遮音タイプでもよく、その他吸音材からなる板状体、コンクリート等、防音性を有しておれば形態や材質、形状等は特に限定されるものではない。なお本形態では前後両側にそれぞれ配置された防音板4において、一方の防音板4では、他方の防音板4の背面板43により遮音されるために、背面板が省略され、コスト低減、軽量化がなされている。
【0021】
上記形態による防音壁の施工方法を説明すると、まず、外側面に前後に相対向するフランジ11が上下方向に形成された支柱1を、隣り合う支柱1のフランジ11を相対向させて、互いに間隔を隔てて道路や鉄道等に沿って立設する。そして外面に取付ボルト3が突設固定されたクリップ部材2の嵌合溝22を前記フランジ11に相対向させ、その嵌合溝22をフランジ11に嵌合させてクリップ部材2を支柱1の前後両側のフランジ11にそれぞれ取付ける。この取付けた状態において、掛止部23を支柱1の上端に掛止させて脱落を防止する。次いで、防音板4を支柱1の前面側と後面側にそれぞれ配置し、各防音板4の取付孔47をクリップ部材2の取付ボルト3にはめ合わせた後、取付ボルト3にナット31を締めつけ、固定すればよい。
【0022】
なお嵌合溝22内にゴム等の弾性材を取付け、支柱1のフランジ11に嵌合溝22を嵌合させた際に、この弾性材が支柱1のフランジ11に当接するようにすれば、掛止部23に加えてクリップ部材2の脱落防止がより効果的となる。
【0023】
さらに必要に応じて防音板4による車両の騒音を抑制する防音効果に加えて、車両に対する防護効果を具備させるために、支柱1を利用して防護柵としてのボックスビーム5を防音板4の上部及び/又は下部に取付ける。このボックスビーム5の取付けは、支柱1のウエブ12にパドル6を支柱1の上端より突出して取付け、このパドル6に取付ければよい。
【0024】
なおクリップ部材2は、本形態では相対向する前後の止め板部21が上下方向に切れ目なく形成されているが、図6の如く、前面側の止め板部21が取付ボルト3を突設固定した部分のみに形成されていてもよいし、図7の如く背面側の止め板部21が部分的に形成されていてもよく、又掛止部23は、図8の如く、相対向する前後の止め板部21の上部間にプレートを固定して形成されていてもよい。
【0025】
さらに図9の如く、支柱1の前後両側のフランジ11にそれぞれ取付ける二個のクリップ部材2を連結板7により連結一体化したものであってもよい。かかる連結一体化したものを用いて防音板4を取付けた例を図10に示す。
【0026】
又クリップ部材2に取付ボルト3により固定される防音板4の張出部46は、前記図3〜4に示された如く、板状のものであってもよいし、図11に示される如く、ボックス状であってもよく、クリップ部材2の取付ボルト3により固定できる形状であれば、特にその形状は限定されるものではない。この張出部46は前面側寄りに形成すれば、支柱1に取付けた防音板4の納まりがよく、支柱1に対する防音板4の突出を少なくすることができる。
【0027】
【発明の効果】
本発明によれば、防音板を支柱の高さ以上に持ち上げる必要がなく、防音板を支柱にフランジの外側より取付けることができるので、又支柱の上端間にボックスビームが固定されていても、防音板を脱着する際にボックスビームを取り外す必要がないので、防音板の取付け取り外しが容易であり、施工性が良く、工期も短くなる。さらにクリップ部材を介して防音板が支柱に取付けられ、防音板を取付けるために、支柱にボルト孔を開ける必要がないので、支柱の強度は低下せず、又ボルト孔を開けるための加工工数も必要ない。

BACKGROUND OF THE INVENTION
The present invention relates to a soundproof wall that is mainly installed in a median strip or the like.
[0002]
[Prior art]
For example, as a soundproof wall installed in a median or the like, a box beam is fixed between upper ends of pillars made of H-shaped steel standing at appropriate intervals along a road, and the pillars are placed in a lower space of the box beam. Some have soundproofing plates installed. This soundproof wall has a protective effect against the vehicle by the box beam, and also has a soundproof effect by suppressing the noise of the vehicle by a soundproof plate.
[0003]
Conventionally, as a soundproof plate mounting structure in such a soundproof wall, a concave portion into which a flange of a pillar made of H-shaped steel enters is formed in advance on the left and right end faces of the soundproof plate, and the soundproof plate is lifted to the height of the pillar, There is a type in which a soundproof plate is attached to a column by fitting a recess into a flange and dropping it between adjacent columns from above.
[0004]
[Problems to be solved by the invention]
However, in the structure where the soundproof plate is lifted above the height of the column and dropped between adjacent columns, the box beam is fixed between the upper ends of the columns when the soundproof plate is damaged and replaced with another soundproof plate. If this is the case, it is necessary to first remove the box beam, and then attach and detach the soundproof plate. In addition, a new soundproof plate is attached to the lower space of the box beam fixed between the upper ends of the columns using the columns. Even in such a case, there is a problem that it is not easy to attach the soundproof plate and that it takes a long period of time, for example, it is necessary to first remove the box beam and then attach the soundproof plate.
[0005]
Therefore, some bolt holes are made in the flange of the column, and the soundproof plate is bolted directly to the bolt hole, so that the soundproof plate can be attached to the column from the outside of the flange. Opening is not preferable because the strength decreases, and there is a problem that the number of processing steps increases.
[0006]
SUMMARY OF THE INVENTION Accordingly, the present invention solves the above-described problems and provides a soundproof wall that can attach a soundproof plate to a support from the outside of a flange without opening a bolt hole in the support. .
[0007]
[Means for Solving the Problems]

Next, after fitting the mounting hole of the soundproof plate to the mounting bolt of the clip member, a nut may be tightened and fixed to the mounting bolt.
[0009]
Therefore, according to the present invention, it is not necessary to lift the soundproof plate beyond the height of the column, and the soundproof plate can be attached to the column from the outside of the flange, and even if the box beam is fixed between the upper ends of the columns. Since it is not necessary to remove the box beam when detaching the soundproof plate, it is easy to attach and remove the soundproof plate, the workability is good, and the construction period is shortened.
[0010]
Furthermore, according to the present invention, since the soundproof plate is attached to the support via the clip member, and it is not necessary to open a bolt hole in the support in order to attach the soundproof plate, the strength of the support is not lowered, and the bolt hole is not provided. There is no need for processing steps to open.
[0011]
In addition, if a clip part can be latched to a support | pillar by forming a latching part in the upper part of a clip member and making a latch part latch on a support | pillar, a clip member in the state attached to the support | pillar Since the position of the soundproof plate is stabilized and positioning is facilitated, it is possible to prevent the dropout, so that the work for fitting the mounting hole of the soundproof plate to the mounting bolt of the clip member is facilitated.
[0012]
Further, in the present invention, when a protruding portion is formed at the side end of the soundproof plate and a mounting hole is formed in the protruding portion, the mounting hole of the soundproof plate is fitted to the mounting bolt of the clip member. It is easy to fit together, and if this overhanging part is formed closer to the front side, the soundproof plate attached to the column can be accommodated.
[0013]
Further, in the present invention, in addition to the soundproofing effect of suppressing the vehicle noise by the soundproofing plate, the box beam is attached to the upper part and / or the lower part of the soundproofing plate using a support column in order to provide the vehicle with a protective effect. It is preferable.
