【発明の属する技術分野】
本発明は、鉄道や高速道路等に沿い構築した遮音・防風壁において、間隔をおき建て込んだＨ形鋼支柱のフランジ内面に遮音・防風壁板の左右側縁部を配置し挟着して張設する遮音・防風壁板の張設装置に関するものである。
【０００２】
【従来の技術】
最近の遮音・防風壁は、Ｈ形鋼支柱の間に透光性樹脂製の遮音・防風壁板を張設して周囲の環境にマツチさせた構造になっている。また、この遮音・防風壁板の張設装置は、通常、遮音・防風壁板の側縁部に補強枠を嵌着して補強し、その補強枠付き側縁部をＨ形鋼支柱のフランジ間に嵌合したり、必要に応じフランジ及び補強枠付き側縁部にボルト・ナツトを挿着した構造になっているが、透光性樹脂製の遮音・防風壁板は、経済的に肉厚が限定されて比較的に風圧等で湾曲や振動したり損傷し易く、補強枠を施す必要が生じコスト高となる。対応した小型のＨ形鋼支柱が必要になって支柱強度が不足する。湾曲や振動等の繰り返しで損傷、破損して脱落するなどの問題点があるため、最近、図６に示すように比較的に大型のＨ形鋼支柱ａのフランジａ１内面に、遮音・防風壁板ｂの側縁部及び緩衝材ｃを配置し、断面Ｌ形状の挟持金具ｄの挟持部ｄ２で緩衝材ｃを圧縮して、挟持金具ｄの装着部ｄ１とウエブａ２に設けたボルト孔と長孔ａ３にボルト・ナツトｆ，ｇを挿入して締め込み（図中ｅは座金）、Ｈ形鋼支柱のフランジａ１と挟持金具の挟持部ｄ２により遮音・防風壁板ｂの側縁部及び緩衝材ｃを挟着して張設した構造の遮音・防風壁板の張設装置が開発されている。
【０００３】
【発明が解決しようとする課題】
図６に示す遮音・防風壁板の張設装置は、簡単な構造で容易に施工され、大型のＨ形鋼支柱の適用が可能となり所要の支柱強度を確保できるなどの特徴があるが、風圧等による遮音・防風壁板の湾曲や振動の繰り返しにより、次第にボルト・ナツトが弛緩して挟持金具が移動し易くなって、遮音・防風壁板の側縁部の挟持力が低下して遮音・防風壁板が離脱する恐れがあるなどの課題がある。
【０００４】
本発明は、前記のような課題を解決するために開発されたものであって、その目的とする処は、透光性樹脂製の遮音・防風壁板の側縁部に緩衝材を嵌装し、挟持金具にスペーサーを組み合わせ又は斜面と緩衝材を付設して、また、下縁部挟持手段を設けるなど、施工性とともに張設性能、信頼性を向上した遮音・防風壁板の張設装置を提供するにある。
【０００５】
【課題を解決するための手段】
本発明の第１発明は、Ｈ形鋼支柱のフランジ内面に透光性樹脂製の遮音・防風壁板の側縁部を配置し、Ｈ形鋼支柱のウエブに装着した断面Ｌ形状の挟持金具の挟持部で前記の側縁部を挟着して張設した遮音・防風壁において、遮音・防風壁板の緩衝材付き側縁部をフランジ内面に配置し、ウエブに対設した挟持金具の外側に断面コ字状のスペーサーを嵌合して、スペーサーと挟持金具及びウエブに設けたボルト孔と長孔にボルト・ナツトを挿入して締め込み装着し、スペーサーの圧入により挟持金具の挟持部に背圧をかけて緩衝材付き側縁部を締め付け挟着し、かつ、Ｈ形鋼支柱を建て込んだコンクリート基礎上に複数の下縁部挟持手段を間隔をおき設けて、下縁部挟持手段の挟着機構付き本体部により遮音・防風壁板の下縁部を挟着して支持したことを特徴としている。
【０００６】
この構成より、断面コ字状のスペーサーを挟持金具とともにウエブにボルト・ナツトで締め込み装着する簡単な機構で容易に施工される。大型のＨ形鋼支柱の使用を可能として所要の支柱強度を確保するとともに、Ｈ形鋼支柱のフランジと挟持金具の挟持部で遮音・防風壁板の緩衝材付き側縁部を容易に締め付けて精度良く強力に挟着できる。風圧等による遮音・防風壁板の側縁部が湾曲や振動等を繰り返しても、締め付け圧縮された緩衝材の弾性等で適度に許容されて、損傷が防止され挟持性能が維持される。ボルト・ナツトによる締め込みに多少の弛みが生じても、スペーサーによる挟持金具の挟持部に加わる背圧に格別な低下がなく圧縮された緩衝材の弾性で十分にカバーされて挟持性能が長期にわたり確保される。
また、Ｈ形鋼支柱を建て込んだコンクリート基礎上に複数の下縁部挟持手段を間隔をおき設けて、下縁部挟持手段の挟着機構付き本体部によって遮音・防風壁板の下縁部を挟着して支持したので、遮音・防風壁板の上縁部を所定の高さ位置に保持するとともに、風圧等による遮音・防風壁板の湾曲や振動等を低減して、遮音・防風壁板の側縁部における湾曲や振動等の低減にも機能し張設性能、信頼性がさらに高められるなど、総合的に施工性とともに張設性能、信頼性が高められる。
【０００７】
また、本発明の第２発明は、Ｈ形鋼支柱のフランジ内面に透光性樹脂製の遮音・防風壁板の側縁部を配置して、Ｈ形鋼支柱のウエブに装着した断面Ｌ形状の挟持金具の挟持部で前記の側縁部を挟着して張設した遮音・防風壁において、遮音・防風壁板の緩衝材付き側縁部をフランジ内面に配置し、挟持金具の装着部の外面に挟持金具の挟持部側ほど高くなる斜面を突設しかつ装着部の他面に緩衝層を付設した挟持金具とし、この挟持金具の斜面と装着部及びウエブに設けた長孔とボルト孔にボルト・ナツトを嵌挿して締め込み装着し、挟持金具の挟持部によって緩衝材付き側縁部を締め付け挟着したことを特徴としている。
【０００８】
この構成により、斜面及び緩衝層を付設した挟持金具をウエブにボルト・ナツトで締め込み装着する簡単な機構で容易に施工される。大型のＨ形鋼支柱の使用を可能として所要の支柱強度を確保するとともに、遮音・防風壁板の緩衝材付き側縁部に挟持金具の挟持部を適宜の手段で締め付けた状態とし、ウエブに挟持金具の装着部をボルト・ナツトで締め込み装着すると、挟持金具の斜面とボルト又はナツトの係合により、Ｈ形鋼支柱のフランジと挟持金具の挟持部で遮音・防風壁板の緩衝材付き側縁部を容易に締め付けて精度良く強力に挟着できる。遮音・防風壁板の側縁部が湾曲や振動等を繰り返しても、締め付け圧縮された緩衝材の弾性等で適度に許容されて、損傷が防止され挟持性能が維持される。ボルト・ナツトによる締め込みに多少の弛みが生じても、挟持金具の装着部に付設した緩衝層とＨ形鋼支柱のウエブとの摩擦及び弾性や斜面とボルト又はナツトの係合等により、挟持金具の挟持部の移動が防止され、また、圧縮された緩衝材の弾性で十分にカバーされて挟持性能が長期にわたり確保されるなど、優れた張設性能、信頼性が得られる。
【０００９】
また、第２発明において、Ｈ形鋼支柱を建て込んだコンクリート基礎上に複数の下縁部挟持手段を間隔をおき設けて、下縁部挟持手段の挟着機構付き本体部によって遮音・防風壁板の下縁部を挟着して支持したことに特徴を有し、遮音・防風壁板の上縁部を所定の高さ位置に保持するとともに、風圧等による遮音・防風壁板の湾曲や振動等を低減して、遮音・防風壁板の側縁部における湾曲や振動等の低減にも機能し張設性能、信頼性がさらに高められるなど、総合的に施工性とともに張設性能、信頼性が高められている。

【００１３】
前記の遮音・防風壁板の張設装置において、Ｈ形鋼支柱１を建て込んだコンクリート基礎３０上に複数の下縁部挟持手段２０を間隔をおき設けて、下縁部挟持手段の挟着機構２１付き本体部２０ａで遮音・防風壁板２の下縁部２ｂを挟着して支持したことを特徴とする遮音・防風壁板の張設装置になっている。
【００１４】
さらに詳述すると、Ｈ形鋼支柱１は、Ｈ形鋼材や断面Ｈ形状の組鋼材を適用して、このウエブ１ｂにボルト７ａを挿入する複数の長孔１ｃ（第１実施例）又は丸孔の複数のボルト孔１ｄ（第２実施例）を適宜の上下間隔で設けて、防音・防風壁板２の側縁部を適宜の上下間隔をおき複数の箇所で挟着する構造になっている。鉄道や高速道路等の側部に沿つて設けた鉄筋や鉄骨鉄筋のコンクリート基礎３０等に、図５に示すように適宜の相互間隔をおき複数のアンカーで建て込み、又は、コンクリート基礎内に下部を埋設したり、コンクリート基礎の側部に適宜の手段で装着するなどして建て込み、Ｈ形鋼支柱の一方のフランジ１ａ内面に遮音・防風壁板２の緩衝材３付き側縁部２ａを配置し、第１実施例では挟持金具５にスペーサー６を組み合わせ、第２実施例では挟持金具１５に斜面１６ａ及び緩衝層１７を付設して、ホルト・ナツト７ａ，７ｂ等による挿入、締め込みにより、このＨ形鋼支柱１に遮音・防風壁板２の左右の側縁部２ａ，２ａを装着する。
【００１５】
遮音・防風壁板２は、耐風強度を有し太陽光線等の自然環境で変質し難たい例えばアクリル樹脂等の各種のプラスチック板、又は補強繊維入り補強プラスチック板等を適用し、透明又は半透明で必要に応じ適度に着色するとともに、風圧等に対応させて適宜の肉厚に形成した各種の透光性樹脂製とし、左右の側縁部２ａをＨ形鋼支柱１のフランジ１ａ内面に装着してＨ形鋼支柱の間に張設し、格別に視界を妨げないで周囲の環境にマツチせしめて防音や防風の機能を発揮する。
【００１６】
緩衝材３は、図３に示すようにゴムや各種のプラスチック、繊維等で補強したプラスチック、又は各種の不織繊維等により、適度の弾性、摩擦性及び厚さサイズを有し、遮音・防風壁板２に対応した断面コ字状に形成する。また、好ましくは図示のように内外面に間隔をおき複数の突起３ａを付設するなど、遮音・防風壁板２の端縁部の全長にわたつて嵌着する構造になっている。
【００１７】
第１実施例の挟持金具５は、図１Ａに示すようにアングル形鋼等の断面Ｌ形状の形鋼材（アングル形鋼材等）からなり、この一半部にボルト孔５ｃを設けてウエブ１ｂへの装着部５ａとし、装着部５ａに対し直角の他半部を遮音・防風壁板２の端縁部への挟持部５ｂとした構造になっている。また、スペーサー６は、図１Ｂ，Ｃに示すように適宜の厚さサイズの鋼板の中央部にボルト孔６ｃを設けた基板部６ａと、この両側に鈍角αで先端側を適度に拡大して連設した一対の斜板部６ｂ，６ｂとからなり、断面コ字状に形成した構造になっている。図１ＡのようにＨ形鋼支柱１のウエブ１ｂに対設した挟持金具５の挟持部５ｂと他側のフランジ１ａ内面との間に配置して挟持金具５の外側に組み合わせ、ボルト・ナツト７ａ，７ｂ（図中７ｃは座金）でウエブ１ｂに締め付けて、スペーサー６を圧入してこの斜板部６ｂで挟持金具の挟持部５ｂに強い背圧Ｆをかけて、挟持部５ｂによりフランジ１ａ内面に配置した遮音・防風壁板２の緩衝材３付き端縁部２ａを強く挟着する構造になっている。
【００１８】
第２実施例の挟持金具１５は、図２Ｂ，Ｃに示すように基本的には第１実施例と同様なアングル形鋼等の断面Ｌ形状の形鋼材を適用し、この装着部１５ａの外面に挟持部１５ｂ側ほど高くなる突起部１６を一体的に突設して斜面１６ａを設け、この反対面に好ましくは挟持部１５ｂ側ほど薄くなる弾性層１７を適宜の手段で設けて、この斜面１６ａと装着部１５ａ及び弾性層１７に長孔１８を貫設した構造になっている。この挟持金具１５は、図２ＡのようにＨ形鋼支柱１のウエブ１ｂに対設し、図示省略した適宜の手段でこの挟持部１５ｂを遮音・防風壁板２の緩衝材３付き側縁部上に強く押しつけて、ボルト・ナツト７ａ，７ｂ等でこの装着部１５ａをウエブ１ｂに締め付けて装着することにより、挟持部１５ｂによりフランジ１ａ内面に配置した遮音・防風壁板２の緩衝材３付き端縁部２ａを強く挟着する構造になっている。
【００１９】
下縁部挟持手段２０は、図４に示すように遮音・防風壁板２の下縁部を嵌合して挟持する断面Ｕ形状の本体部２０ａと、本体部２０ａの下面側に固着したボルト２０ｂと、本体部２０ａの一側面に座金２１ａを配置し螺合して進退するボルト２１ｂと，及びボルトの内端部に回転可能に装着して本体部２０ａ内に配置した挟持板２１ｃからなる挟持機構２１、及びコンクリート基礎３０の上部に埋設する雌ネジ付きのアンカー２０ｃ等で構成している。図５に示すようにコンクリート基礎３０の上部に間隔をおき埋設したアンカー２０ｃにボルト２０ｂをねじ込み、必要に応じ止ナツト（図示省略）で所要の高さに固定して、コンクリート基礎上に本体部２０ａを適宜の高さに調節して配置し、本体部２０ａ内に遮音・防風壁板２の下縁部２ｂを嵌合してボルト２１ｂをねじ込み、挟持板２１ｃと本体部２０ａの側面で遮音・防風壁板の下縁部２ｂを挟着する構造になっている。また、必要に応じその下縁部２ｂに緩衝材２２ｃ（図３に示す断面コ字状の緩衝材３を参照）を嵌着するなどして、遮音・防風壁板の下縁部２ｂに挟着する。
【００２０】
図１Ａに示す第１実施例は、鉄道、高速道路等の側部に沿つて構築した遮音・防風壁において、Ｈ形鋼支柱１の両側に透光性樹脂製の遮音・防風壁板２の緩衝材３付き端縁部を挟着した実施例である。図１Ａのように遮音・防風壁板２の左右の側縁部２ａに緩衝材３を装着して、この緩衝材３付き側縁部をＨ形鋼支柱１のフランジ１ａの左右の内面に配置し、挟持金具５をＨ形鋼支柱１のウエブ１ｂに対設して、挟持金具５の外側に断面コ字状のスペーサー６を嵌合して組み合わせ、挟持金具５とスペーサー６及びウエブ１ｂに設けたボルト孔６ｃ，５ｃ及び長孔１ｃに、座金７ｃを使用してボルト・ナツト７ａ，７ｂを嵌挿して締め込むと、スペーサー６が挟持金具の挟持部５ｂと支柱フランジ１ａ内面との間に圧入されて、スペーサーの斜板部６ｂによって挟持金具の挟持部５ｂに強力な背圧Ｆがかかり、挟持金具の挟持部５ｂによって遮音・防風壁板２の緩衝材３付き側縁部２ａを強力に挟着した構造に容易に施工される。図５のようにコンクリート基礎３０に建て込んだＨ形鋼支柱１の間に遮音・防風壁板２を張設して遮音・防風壁に構築する。端末のＨ形鋼支柱１の場合は、そのフランジ１ａ内面の一方側のみに遮音・防風壁板の緩衝材３付き側縁部２ａを同様に強力に挟着する。また、ボルト孔６ｃ，５ｃを長孔とし、対応させてボルトを挿入する通常のボルト孔１ｃにしても同様に施工される。
【００２１】
第１実施例の遮音・防風壁板の張設構造は、前記のような構造からなり、挟持金具５の外側に断面コ字状のスペーサー６を嵌合させて組み合わせ、Ｈ形鋼支柱１のウエブ１ｂにスペーサー６及び挟持金具５をボルト・ナツト７ａ，７ｂ等で挿入して締め付ける比較的に簡単に構造となり、遮音・防風壁板１の緩衝材３付き側縁部２ａを強力に挟着して容易に施工することができる。このＨ形鋼支柱１は遮音・防風壁板２の肉厚に関係なく大型の形鋼を使用でき、所要の支柱強度を確保することができる。また、ボルト・ナツト７ａ，７ｂ等の締め込みによるスペーサー６の圧入により、斜板部６ｂで挟持金具５の挟持部５ｂに強い背圧Ｆをかけて、遮音・防風壁板１の緩衝材３付き側縁部２ａをその挟持部５ｂとＨ形鋼支柱１のフランジ１ａで挟着するため、遮音・防風壁板の緩衝材３付き側縁部２ａが格別なバラツキもなく強力に精度良く挟着されて、風圧等により遮音・防風壁板の側縁部２ａに湾曲や振動等が繰り返されても、その側縁部２ａが圧縮された緩衝材３の摩擦支持及び適度の弾性によって適度に許容されるなど、損傷が防止されてその優れた挟着性能が維持される。また、ボルト・ナツト７ａ，７ｂによる締め込みに多少の弛みが生じても、スペーサー６によって挟持金具の挟持部５ｂにかかる背圧Ｆが格別な低下されないで、圧縮された緩衝材３の弾性でその低下が十分にカバーされて挟着性能が長期にわたり確保されるなど、施工性とともに張設性能、信頼性を著しく高めている。
【００２２】
図２Ａに示す第２実施例は、Ｈ形鋼支柱１のフランジ両側に透光性樹脂製の遮音・防風壁板２の緩衝材３付き端縁部２ａを挟着した実施例である。図２に示すように遮音・防風壁板２の緩衝材３付き端縁部２ａをＨ形鋼支柱１のフランジ１ａ内面に配置し、図２Ｂ，Ｃに示す挟持金具１５をウエブ１ｂに配置し、挟持金具の挟持部１５ｂを適宜の手段で緩衝材３付き端縁部２ａに押し付けて、ボルト・ナツト７ａ，７ｂを挟持金具１５の長孔１８及びウエブ１ｂのボルト孔１ｄに嵌挿して締め込むことにより、Ｈ形鋼支柱１のフランジ１ａと挟持金具１５の挟持部１５ｂで遮音・防風壁板２の緩衝材３付き端縁部２ａを強力に挟着して施工する。図５に示すようにコンクリート基礎３０に建て込んだＨ形鋼支柱１の間に遮音・防風壁板２を張設して遮音・防風壁に構築する。
【００２３】
第２実施例の遮音・防風壁板の張設構造は、前記のような構造からなり、Ｈ形鋼支柱１のウエブ１ｂに、斜面１６ａと緩衝層１７を付設した挟持金具１５をボルト・ナツト７ａ，７ｂ等により挿入して締め付ける比較的に簡単に構造で、遮音・防風壁板１の緩衝材３付き側端部２ａを容易に挟着して施工できる。このＨ形鋼支柱１は遮音・防風壁板２の肉厚に関係なく大型の形鋼を使用でき、所要の支柱強度を確保することができる。挟持金具１５の挟着部１５ａの外面に斜面１６ａを突設して他面に緩衝層１７を付設した構造になっているので、ボルト・ナツト７ａ，７ｂ等の挿入、締め付けに際し格別なバラツキを生じないで、Ｈ形鋼支柱１のフランジ１ａと挟持金具１５の挟持部１５ｂで遮音・防風壁板１の緩衝材３付き側端部２ａを強力に精度良く挟着することができて、風圧等により遮音・防風壁板の側縁部２ａが湾曲や振動等を繰り返しても、この側縁部２ａが圧縮された緩衝材３の摩擦支持と適度の弾性により適度に許容されるなど、損傷が防止されて優れた挟着性能が維持される。また、ボルト・ナツト７ａ，７ｂ等による締め込みに多少の弛みが生じても、緩衝層１７によるウエブ１ｂとの弾性や摩擦、斜面１６ａとボルト７ａ又はナツト７ｂとの係合や、緩衝材３の弾性等により挟持金具１５の移動変位が格別に生じないで、優れた挟着性能が長期にわたり確保されるなど、施工性とともに張設性能、信頼性を著しく高めている。端末のＨ形鋼支柱においては、そのフランジ１ａ内面の一方側のみに遮音・防風壁板２の側縁部を配置して同様に挟着する。
【００２４】
図５に示す実施例は、コンクリート基礎３０上に複数のＨ形鋼支柱１を相互間隔をおき建て込むとともに、コンクリート基礎３０上に下縁部挟持手段２０を適宜の相互間隔をおき所要の高さに調節して配置し、各下縁部挟持手段２０の本体部２０ａ内に透光性樹脂製の遮音・防風壁板２の緩衝材２２ｃ付き下縁部２ｂを嵌合して、ボルト２１ｂをねじ込み本体部２０ａの側部と挟持板２１ｃで遮音・防風壁板２の下縁部を挟着して所要の高さに支持し、また、必要に応じ図示のよのように支柱間に架設した横架材４（断面Ｈ形状の鋼材）の下側溝と上側溝（図示省略）に、下側と上側の遮音・防風壁板２の上縁部及び下縁部を嵌合して、各遮音・防風壁板２の左右の側縁部２ａを第１実施例の張設装置１０ａ（図１参照）又は第２実施例の張設装置１０ｂ（図１参照）により適度の上下間隔をおき複数箇所で挟着して張設した遮音・防風壁に構築した実施例である。
【００２５】
前記の遮音・防風壁は、コンクリート基礎３０上に適宜の間隔をおき配置して所要高さに調節される下縁部挟持手段２０の挟持機構２１付き本体部２０ａにより、遮音・防風壁板２の下縁部２ｂを所要の高さで容易に挟着でき、遮音・防風壁板２の高さ配置の精度を高めるとともに、風圧等による遮音・防風壁板２の湾曲や振動等を著しく低減する。また、支柱間に架設した横架材４によっても遮音・防風壁板２の湾曲や振動等を著しく低減する。従って、遮音・防風壁板２の左右の側縁部２ａにおける湾曲や振動等が基本的に低減されて、前記の第１実施例及び第２実施例の張設性能、信頼性をさらに高める。
【００２６】
図１に示すスペーサー６は、基本的な形状を示す実施例であつて、必要に応じ実施例の斜板部６ｂの先端部にさらに補強部材を一体的に曲設するなど、各種の改変が可能である。
