Description

【０００１】
【発明の属する技術分野】
本発明は、線路の軌間外においてレールの外側とアスファルト舗装との間に設けられ道路の路面を構成する線路軌間外舗装構造、及び線路の軌間外において道路の路面を構成する線路軌間外の舗装方法に関するものである。
【０００２】
【従来の技術】
従来、レール（軌条）とまくらぎを有する鉄道線路と道路が平面交差する踏切道においては、歩行者や自動車等の通行のため、線路の軌間内及び軌間外に舗装を行っていた。このような踏切構造として、出願人は、特開平５−１１８００４号公報に開示された構造を提案している。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記した公報に開示された踏切構造には、以下のような課題があった。
【０００４】
（ａ）上記公報の踏切構造の道路部分を横断する対象は、駅構内の鉄道職員等の人間であるが、耕運機や軽自動車等の車両が通行できる程度の強度を持たせ、農道等においても設置したい、という要請があった。
【０００５】
（ｂ）軌道保守を機械的に行うマルチプル・タイタンパー（以下、「ＭＴＴ」という。）により道床砕石の突き固めを行う場合、ＭＴＴのタンピング・ツール（道床砕石突き固めを行うために砕石中に差し込み振動を付加するむ部分）を道床砕石中に差し込むため、上記公報の踏切構造の渡板等をＭＴＴの作業開始前に撤去する必要があり、ＭＴＴの作業終了後には渡板等を復旧する必要がある。ＭＴＴの軌道保守作業は、列車の運転されない時間帯、例えば夜間等の短い時間間隔（以下、「間合」という。）に行われることが多い。このため、渡板等の撤去・復旧が短時間で行える構造であることが必要である。
【０００６】
（ｃ）ＭＴＴにより軌道保守作業を行うと、レールの位置も所定の位置に修正される。したがって、ＭＴＴ作業終了後の渡板の位置がＭＴＴ作業開始前の位置からずれる場合がある。レール位置が線路の長手方向に直角な方向にずれると、踏切道に接続する接続道路との取付部分において、一方の箇所では軌間外の渡板と接続道路との間に隙間があき、他方の箇所では接続道路のアスファルト舗装等を切断・除去しないと軌間外の渡板等が設置できないという問題が生じる。このようなアスファルト舗装等の撤去作業には長い時間が必要であるため、改善が要請されていた。
【０００７】
（ｄ）上記公報の踏切構造では、軌間外の渡板は支持梁で支持される。この支持梁の一端はレールの軌間外側で支持され、支持梁の他端は固定ブロックで支持されるようになっている。しかし、固定ブロックの材料費、及び固定ブロックの据え付け工事費は高価である、という問題がある。また、橋梁や鉄道信号機の近傍では、固定ブロックを設置できない、という問題もあった。
【０００８】
本発明は上記の問題を解決するためになされたものであり、本発明の解決しようとする課題は、取り付け・撤去が容易で、位置がずれた場合でも接続道路のアスファルト舗装の除去等が不要な線路軌間外舗装構造、及び線路軌間外の舗装方法を提供することにある。
【０００９】
【課題を解決するための手段】
上記課題を解決するため、本発明に係る線路軌間外舗装構造は、線路の軌間外においてレールの外側とアスファルト舗装との間に設けられる線路軌間外舗装構造であって、レールの外側に配置されると共に道路の路面を構成する軌間外軌道舗装部材と、まくらぎの軌間外側端部付近に取り付けられると共に前記軌間外軌道舗装部材から前記アスファルト舗装へ向けて突出するまくらぎ取付手段と、一端部付近が前記レールの軌間外側により支承されるとともに他端部付近が前記まくらぎ取付手段によって支承され且つ前記軌間外軌道舗装部材を支持する舗装部材支持梁手段とを備え、前記軌間外軌道舗装部材と前記アスファルト舗装との間において線路長手方向に沿って延設されると共に前記まくらぎ取付手段に固定され、前記アスファルト舗装の前記軌間外軌道舗装部材に対向する軌道側アスファルト端面をせき止めるアスファルト舗装塞止手段と、前記アスファルト舗装塞止手段と前記アスファルト舗装との間に配置され且つ前記アスファルト舗装塞止手段に取り付けられるとともに前記アスファルト舗装塞止手段の道路長手方向のせき止め厚さを調整する塞止厚調整手段を備えることを特徴とする。
【００１２】
また、上記の線路軌間外舗装構造において、好ましくは、前記アスファルト舗装塞止手段と前記レールの軌間外側の間に配置されるとともに前記舗装部材支持梁手段の端部を前記レールの軌間外側表面に押接させるレール押接手段を備える。
【００１３】
また、上記の線路軌間外舗装構造において、好ましくは、前記軌間外軌道舗装部材の線路長手方向の長さは、前記まくらぎの線路長手方向の設置間隔の整数倍に設定される。
【００１４】

【００１５】
また、上記の線路軌間外舗装構造において、好ましくは、前記複数の軌間外軌道舗装部材を支持する複数の舗装部材支持梁手段のうち、線路長手方向における両端部の舗装部材支持梁手段を前記まくらぎ取付手段に連結し固定する支持梁連結手段を備える。
【００１６】
また、上記の線路軌間外舗装構造において、好ましくは、前記まくらぎ取付手段は、線路長手方向に沿って延設されるとともに複数のまくらぎに取り付けられ、前記複数のまくらぎの相互間の間隔が変動することを防止する。
【００１７】
また、上記の線路軌間外舗装構造において、好ましくは、前記まくらぎ取付手段は、取り付けられる複数のまくらぎの位置に応じて前記まくらぎ取付手段の取付位置を調整可能な取付位置調整手段を備える。
【００１８】
また、上記の線路軌間外舗装構造において、好ましくは、前記軌間外軌道舗装部材は、軽量で所定強度と電気絶縁性を有する合成樹脂材料又は繊維強化合成樹脂複合材料により形成される。
【００１９】
また、本発明に係る線路軌間外の舗装方法は、線路の軌間外においてレールの外側とアスファルト舗装との間に設けられる線路軌間外の舗装方法であって、道路の路面を構成する軌間外軌道舗装部材をレールの外側に配置し、前記軌間外軌道舗装部材から前記アスファルト舗装へ向けて突出するまくらぎ取付手段をまくらぎの軌間外側端部付近に取り付け、前記軌間外軌道舗装部材を前記舗装部材支持梁手段により支持し、舗装部材支持梁手段の一端部付近を前記レールの軌間外側により支承させるとともに前記舗装部材支持梁手段の他端部付近を前記まくらぎ取付手段によって支承させ、前記軌間外軌道舗装部材と前記アスファルト舗装との間において線路長手方向に沿って延設されると共に前記アスファルト舗装の前記軌間外軌道舗装部材に対向する軌道側アスファルト端面をせき止めるアスファルト舗装塞止手段を前記まくらぎ取付手段に固定し、前記アスファルト舗装塞止手段の道路長手方向のせき止め厚さを調整する塞止厚調整手段を前記アスファルト舗装塞止手段と前記アスファルト舗装との間に配置し且つ前記アスファルト舗装塞止手段に取り付けることを特徴とする。
【００２０】
上記の線路軌間外の舗装方法において、好ましくは、前記舗装部材支持梁手段は、前記まくらぎ取付手段に取り付ける前にあらかじめ前記軌間外軌道舗装部材と接合される。
【００２１】
【発明の実施の形態】
以下、本発明の実施形態について、図面を参照しながら説明する。
【００２２】
図１は、本発明の一実施形態である線路軌間外舗装構造を用いた踏切道の構成を示す斜視図である。また、図２は、図１に示す線路軌間外舗装構造のさらに詳細な構成を示す図であり、線路長手方向から見た正面図である。また、図３は、図１に示す線路軌間外舗装構造のさらに詳細な構成を示す図であり、上方から見た上面図である。また、図４は、図１に示す線路軌間外舗装構造のさらに詳細な構成を示す図であり、図２におけるＡ−Ａ方向の断面図である。また、図５ないし図８は、図１に示す線路軌間外舗装構造に用いる部品のさらに詳細な構成を示す図である。
【００２３】
図１に示すように、この踏切道１は、踏切の軌間内（内軌側）に設置される線路軌間内舗装構造５と、踏切の軌間外（外軌側）の一方のアスファルト舗装接続道路４と一方のレール２の外側と間に設置される線路軌間外舗装構造１０と、踏切の軌間外（外軌側）の他方のアスファルト舗装接続道路４´と他方のレール２´の外側と間に設置される線路軌間外舗装構造１０´を備えて構成されている。
【００２４】
線路軌間内舗装構造５は、複数の軌間内踏切舗装部材５１と、軌間内踏切舗装部材５１を支持する軌間内支持梁部５２と、軌間内支持梁部５２の両端に設けられるレール当接部５３を有している。線路軌間内舗装構造５は、軌間内踏切舗装部材５１の路面板が、後述する軌間外踏切舗装部材１１の路面板１４と同様の材質であることを除き、上記した特開平５−１１８００４号公報に開示された踏切構造の線路軌間内と同様の構成と作用を有しているため、その説明は省略する。
【００２５】
また、線路軌間外舗装構造１０´は、線路軌間外舗装構造１０と同様の構成を有しているため、以下の説明は線路軌間外舗装構造１０について行う。
【００２６】
図１に示すように、線路軌間外舗装構造１０は、複数の軌間外踏切舗装部材１１と、まくらぎ取付部１２と、舗装部材支持梁部１３を備えている。
【００２７】
軌間外踏切舗装部材１１は、踏切道１の軌間外（外軌側）の道路の路面を構成しており、軌間外踏切舗装部材に相当している。また、まくらぎ取付部１２は、まくらぎ３の軌間外の側端部付近に取り付けられており、まくらぎ取付手段に相当している。また、舗装部材支持梁部１３は、その一端部付近がレール２の軌間外側により支承され、その他端部付近がまくらぎ取付部１２によって支承されており、これにより軌間外踏切舗装部材１１を支持しており、舗装部材支持梁手段に相当している。
【００２８】
また、まくらぎ取付部１２の一部である仕切板部１２ｃは、線路の長手方向に沿って延びるようにまくらぎ取付部１２に一体形成され、アスファルト舗装接続道路４の軌間外踏切舗装部材１１に対向する端面３３（以下、「軌道側アスファルト端面」という。図２、３を参照。）をせき止めており、アスファルト舗装塞止手段に相当している。
【００２９】
また、線路軌間外舗装構造１０は、上記の構成要素のほかに、塞止厚調整部材１５を備えている。塞止厚調整部材１５は、仕切板部１２ｃに取り付けられ、仕切板部１２ｃの道路長手方向のせき止め厚さを調整する機能を有しており、塞止厚調整手段に相当している。また、塞止厚調整部材１５はアスファルト舗装塞止手段にも相当している。
【００３０】
また、線路軌間外舗装構造１０は、上記の構成要素のほかに、角材２８を備えている。角材２８は、仕切板部１２ｃとレール２の軌間外側の間に配置され、舗装部材支持梁部１３の端部をレール２の軌間外側表面に押接させる機能を有しており、レール押接手段に相当している。
【００３１】
また、線路軌間外舗装構造１０は、上記の構成要素のほかに、路面板結束具１７を備えている。路面板結束具１７は、複数の路面板１４を結束する機能を有しており、路面板結束手段に相当している。
【００３２】
次に、図２ないし図８を参照し、線路軌間外舗装構造１０のさらに詳細な構成と作用について説明を行う。
【００３３】
まず、図７に基き、まくらぎ取付部１２のさらに詳細な構成と作用について説明する。図７（Ａ）は、まくらぎ取付部１２の上面図であり、図の左右方向が線路長手方向である。図７（Ａ）に示すように、まくらぎ取付部１２は、鋼材等からなり、線路長手方向（レール２の長手方向）に延びる仕切板部１２ｃと、仕切板部１２ｃにまくらぎ３の配置間隔で溶接等により接合された複数の平板部１２ａ１、１２ａ２、１２ａ３等を有している。
【００３４】
平板部１２ａ１、１２ａ２、１２ａ３が仕切板部１２ｃに接合する箇所の付近の下方には、張出補強部１２ｂ１、１２ｂ２、１２ｂ３が溶接等により接合されている。また、平板部１２ａ１と１２ａ３の上面には、ボルト受部１２ｄ１、１２ｄ２、１２ｄ３が溶接等により接合されている。
【００３５】
また、平板部１２ａ１と１２ａ２には、ボルトを取り付けるための長穴１２ｅ１、１２ｅ２が設けられている。また、平板部１２ａ３には、ボルトを取り付けるための円形穴１２ｅ３が設けられている。また、仕切板部１２ｃの線路長手方向の両端付近には、ボルト穴１２ｆが設けられている。このボルト穴１２ｆは、後述するボルト２９ａにより角材２８と塞止厚調整部材１５を固定するための穴である。また、ボルト受部１２ｄ１、１２ｄ２、１２ｄ３には、ボルトを取り付けるためのボルト穴１２ｇ１、１２ｇ２、１２ｇ３が設けられている。
【００３６】
上記のような構成により、図７（Ｂ）に示すように、まくらぎ３の軌間外の側端部付近に、内壁に雌ねじを有するボルト用埋込栓３ａを設けておけば、ボルト２６により平板部１２ａ２等をまくらぎ３の軌間外側端部付近に取り付けることができる。この際、まくらぎ３の上面と平板部１２ａ２等との間にはゴム等からなるパッキング材３１、３２（図４参照）などを挟み込み、がたつき等を防止する。
【００３７】
また、平板部１２ａ１、１２ａ２のボルト穴１２ｅ１、１２ｅ２は、線路長手方向に長い長穴であるため、まくらぎ取付部１２の取り付けを行う箇所の複数のまくらぎ３の間隔にずれやばらつき等があっても、これらを吸収し、取り付けられる複数のまくらぎ３の位置に応じて、まくらぎ取付部１２の取付位置を調整することができる。長穴１２ｅ１、１２ｅ２は、取付位置調整手段に相当している。
【００３８】
また、まくらぎ取付部１２は、線路長手方向に沿って延設され、複数のまくらぎ３に取り付けられ、これらを拘束するため、取り付けられた後は、複数のまくらぎ３の相互間の間隔が変動することを防止することができる。
【００３９】
次に、図６に基き、軌間外踏切舗装部材１１のさらに詳細な構成と作用について説明する。図６（Ａ）は、軌間外踏切舗装部材１１の線路長手方向から見た正面図であり、図の手前から奥に向かう方向が線路長手方向である。また、図６（Ｂ）は、図６（Ａ）におけるＢ−Ｂ方向の断面図であり、図の左右方向が線路長手方向である。
【００４０】
図６に示すように、軌間外踏切舗装部材１１は、路面板取付部材２１及び２２と、複数の路面板１４と、路面板結束具１７と、皿ネジ２０ａを有している。
【００４１】
路面板取付部材２１と２２は、後述するボルト受部２１ｃと２２ｃの大きさが異なる点を除き同様の構成を有している。以下、路面板取付部材２２について、その構成と作用を説明する。路面板取付部材２２は、山形水平部２２ａと、山形垂下部２２ｂと、２つのボルト受部２２ｃを有する鋼製部材である。
【００４２】
山形水平部２２ａと山形垂下部２２ｂは、「Ｌ」字状の断面を形成し、山形垂下部２２ｂの一部（線路長手方向の両端付近）は除去されている。また、ボルト受部２２ｃは、山形水平部２２ａの両端付近の下方に溶接等により接合され、垂下する片状の部分となっている。また、ボルト受部２２ｃには、ボルトを挿通するためのボルト穴２２ｄが設けられている。また、山形水平部２２ａには、ボルトを挿通するためのボルト穴２２ｅが複数個設けられている。
【００４３】
路面板１４は、合成樹脂の母材中にガラスや炭素等の繊維が埋設されて補強された繊維強化合成樹脂複合材料（繊維強化プラスチック）等から形成される板状部材であり、軽量であるとともに、上面を通行する車両荷重に耐える所定の強度を有し、かつレールに流れる鉄道信号を短絡させるおそれのない電気絶縁性を有している。
【００４４】
また、路面板１４には、上面に浅い溝部１４ａ、１４ｂが設けられ、この溝部１４ａ、１４ｂの底部から路面板１４の下面に貫通する貫通孔１４ｃ、１４ｄが複数設けられている。
【００４５】
路面板結束具１７は、金属等からなる細い板状の部材であり、溝部１４ａ、１４ｂ内に収容可能となっている。また、路面板結束具１７には、貫通孔１４ｃ、１４ｄに対応する位置にすり鉢状又は皿状の開口が設けられている。皿ネジ２０ａは、頭部が皿状に形成されたネジであり、この頭部は、路面板結束具１７の開口に嵌合するようになっている。
【００４６】
上記のような構成により、図６に示すように、路面板取付部材２１、２２の山形水平部２１ａ、２２ａの上面に所定個数の路面板１４を載置し、溝部１４ａ、１４ｂ内に路面板結束具１７を収め、皿ネジ２０ａを貫通孔１４ｃ、１４ｄに挿通し、山形水平部２１ａ、２２ａの下面でナット２０ｂにより締結すれば、軌間外踏切舗装部材１１を形成することができる。
【００４７】
この場合、軌間外踏切舗装部材１１の線路長手方向の長さは、まくらぎ３の線路長手方向の設置間隔（ピッチ）の１個分、あるいはｎ個分（ｎ：２以上の整数）とすることができる。ボルト受部２１ｃ、２２ｃは、舗装部材支持梁部１３とまくらぎ固定部１２により、まくらぎ３の上で支持される。したがって、軌間外踏切舗装部材１１の線路長手方向の長さが、まくらぎ３の線路長手方向の設置間隔（ピッチ）の１個分の場合には、すべてのまくらぎ３の上で軌間外踏切舗装部材１１の両端が支持されることになる。また、軌間外踏切舗装部材１１の線路長手方向の長さが、まくらぎ３の線路長手方向の設置間隔（ピッチ）のｎ個分（ｎ：２以上の整数）の場合には、何個かごとの特定のまくらぎ３の上で軌間外踏切舗装部材１１の両端が支持されることになる。
【００４８】
次に、舗装部材支持梁部１３のさらに詳細な構成と作用について説明する。図２、図３、図４に示すように、軌間外踏切舗装部材１１の下方には、舗装部材支持梁部１３が設けられ、軌間外踏切舗装部材１１を支持している。また、舗装部材支持梁部１３の一端部（レール側の端部）付近は、レール２の軌間外側のレール底部により支承されている。また、舗装部材支持梁部１３の他端部（アスファルト舗装接続道路側の端部）付近は、まくらぎ取付部１２の平板部１２ａ１によって支承されている。
【００４９】
図８は、軌間外踏切舗装部材１１の下方に舗装部材支持梁部１３が取り付けられた状態を示した図である。図８（Ａ）は、線路長手方向から見た正面図であり、図の手前から奥に向かう方向が線路長手方向である。また、図８（Ｂ）は、図８（Ａ）におけるＣ−Ｃ方向の断面図であり、図の左右方向が線路長手方向である。
【００５０】
図８に示すように、舗装部材支持梁部１３は、２個の梁部材２３と、レール当接部材１６と、４個のボルト２４ａ及びナット２４ｂ（図３参照）と、１個のボルト２５ａ及び２５ｂを有している。
【００５１】
図５（Ａ）、図５（Ｂ）、図５（Ｃ）は、レール当接部材１６の構成を示す３面図である。図に示すように、レール当接部材１６は、水平に突出した２つの突出部１６ａを有し、４つのボルト穴１６ｂを有している。また、レール当接部材１６の前端面１６ｃは、レールの側面の曲面と同様の曲面となっている。
【００５２】
また、図５（Ｄ）、図５（Ｅ）は、梁部材２３の構成を示す図である。図に示すように、梁部材２３は、板状の部材であり、４つのボルト穴２３ａと、ボルト穴２３ｂ、２３ｃを有している。
【００５３】
このような構成により、図５（Ｄ）の状態で２個の梁部材２３が重なるように配置し、２個の梁部材２３の間に挟み込むようにして、図５（Ｄ）における左端部にレール当接部材１６を図５（Ａ）の状態で挿入する。また、２個の梁部材２３の間に、軌間外踏切舗装部材１１のボルト受部２１ｃと２２ｃを挟み込む。この状態で、４つのボルト穴２３ａと１６ｂのそれぞれにボルト２４ａを挿通させ、逆側においてナット２４ｂ（図３参照）で締結する。また、ボルト穴２３ｂと、軌間外踏切舗装部材１１のボルト受部２１ｃのボルト穴２１ｄにボルト２５ａを挿通させ、逆側においてナット２５ｂ（図３参照）で締結する。これにより、図８に示すように、軌間外踏切舗装部材１１の下方に舗装部材支持梁部１３を取り付けることができる。
【００５４】
したがって、まくらぎ取付部１２を、まくらぎ３の軌間外側端部付近に取り付けた後、図８の状態に接合した軌間外踏切舗装部材１１と舗装部材支持梁部１３との接合体を軌間外に据え付け、図８の接合体のボルト穴２３ｃをまくらぎ取付部１２の両端のボルト受部１２ｄ１のボルト穴１２ｇ１（図３、４、７を参照）に重ね合わせ、長尺ボルト２７（図２、３、４を参照）を挿通し、反対側の端部でナット（図示せず）により締結すれば、複数の舗装部材支持梁部１３のうち、線路長手方向における両端部の舗装部材支持梁部をまくらぎ取付部１２のボルト受部１２ｄ１に連結し固定することができる。ここに、長尺ボルト２７は、支持梁連結手段に相当している。
【００５５】
したがって、軌間外踏切舗装部材１１と舗装部材支持梁部１３との接合体の着脱は、長尺ボルト２７によって行うことができ、非常に容易である。
【００５６】
本実施形態の線路軌間外舗装構造１０においては、仕切板部１２ｃと路面板１４の間に角材２８を挿入配置するようになっている。角材２８の両端には貫通孔２８ａが設けられており、ボルト２９ａとナット２９ｂにより仕切板部１２ｃに固定される構成となっている。このような構成により、角材２８は、梁部材２３の端部（図２における右端部）を図２の左方へ向けて押接する。このため、梁部材２３の他端部（図２における左端部）のレール当接部材１６の前端面１６ｃは、レール２の軌間外側の腹部表面に押接され、線路軌間外舗装構造１０にはがたつきや隙間が生じることがなく、軌間外の所定位置に強固に固定される。
【００５７】
また、本実施形態の線路軌間外舗装構造１０においては、仕切板部１２ｃとアスファルト舗装接続道路４の間に塞止厚調整部材１５を挿入配置するようになっている。塞止厚調整部材１５の両端には貫通孔１５ａが設けられており、上記したボルト２９ａとナット２９ｂにより仕切板部１２ｃに固定される構成となっている。
【００５８】
このような構成により、本実施形態の線路軌間外舗装構造１０は、塞止厚調整部材１５の一面（図２における右面）は、アスファルト舗装接続道路４の軌道側アスファルト端面３３と当接してせき止める。踏切道１の軌道保守作業により軌道中心線が線路直角方向に作業前の位置からずれた場合には、他の塞止厚調整部材１５をさらに挿入したり、塞止厚調整部材１５を抜き取ることにより、軌道側アスファルト端面３３との距離を自在に調整することができる。これにより、アスファルト舗装４を切断・除去する必要はない。また、塞止厚調整部材１５を付加、又は取り外す場合には、ボルト２９ａ、ナット２９ｂは、アスファルト舗装接続道路４の延設方向から見た場合に左又は右の側端となる位置のさらに外方の位置に配置されており、外部に露出しているため、ボルト２９ａを緩めて塞止厚調整部材１５を挿入、又は取り外す作業は非常に容易に行うことができる。
【００５９】
なお、本発明は、上記各実施形態に限定されるものではない。上記実施形態は、例示であり、本発明の特許請求の範囲に記載された技術的思想と実質的に同一な構成を有し、同様な作用効果を奏するものは、いかなるものであっても本発明の技術的範囲に包含される。
【００６０】
例えば、上記実施形態においては、軌間外軌道舗装構造として鉄道線路と道路との平面交差部である踏切付近の路面を構成する例について説明したが、本発明はこれには限定されず、軌道は、鉄道線路以外の軌道、例えば路面電車の軌道等であってもよい。また、舗装を行う箇所についても、踏切以外の箇所、例えば路面電車の停留所付近、路面電車の道路交差点付近等であってもよい。
【００６１】
また、上記実施形態においては、路面板として繊維強化合成樹脂複合材料からなる路面板（例えば１１）を例に挙げて説明したが、本発明はこれには限定されず、他の軌道舗装部材、例えば、繊維強化を行わず所定の強度を有する合成樹脂材料からなる路面板、木材や石材等からなる敷材等を用いた路面板等であってもよい。また、上記実施形態においては、軌間外軌道舗装部材（例えば１１）に路面板が線路長手方向に複数個並設される例について説明したが、本発明はこれには限定されず、路面板の個数は１個であってもよい。
【００６２】
また、上記実施形態においては、塞止厚調整手段として板状の塞止厚調整部材（例えば１５）を例に挙げて説明したが、本発明はこれには限定されず、他の構成の塞止厚調整手段、例えば、断面が各種形状の棒状部材、断面が各種形状のパイプ状部材等であってもよい。また、場合によっては、アスファルト舗装塞止手段、塞止厚調整手段は設けなくてもよい。本発明は、少なくとも、軌間外軌道舗装部材と、まくらぎ取付手段と、舗装部材支持梁手段を備えればよいのである。
【００６３】
また、アスファルト舗装塞止手段は、上記実施形態の仕切板部１２ｃのようにまくらぎ取付手段（まくらぎ取付部１２）に一体形成されなくてもよい。まくらぎ取付手段とは別個に形成された部材で、まくらぎ取付手段にボルト等により固定されるような構成であってもよい。
【００６４】
また、上記実施形態においては、舗装部材支持梁手段を軌間外軌道舗装板に接合してから、両者が一体化した接合体をまくらぎ取付手段に取り付けているが、他の手順の方法、例えば、まくらぎ取付手段に舗装部材支持梁手段を取り付け、その後、舗装部材支持梁手段の上に軌間外軌道舗装部材を支持させるようにしてもよい。
【００６５】
【発明の効果】
以上説明したように、本発明によれば、以下のような利点を有している。

(B) By using a fiber reinforced synthetic resin composite material for the road surface plate, the road plate has sufficient strength to allow vehicles such as cultivators and light cars to pass through and can be installed on agricultural roads.
[0067]
(B) If the structure is such that the joint between the track pavement member outside the gauge and the pavement member supporting beam means is integrated and fixed to the sleeper mounting means by the support beam connecting means such as long bolts, the joined body is removed.・ Recovery can be performed in a short time, and work can be easily performed during track maintenance at night.
[0068]
(C) Even if the rail position shifts in the direction perpendicular to the longitudinal direction of the track due to the track maintenance work of the MTT, the distance from the connecting road connected to the railroad crossing is appropriately added and removed. Can be easily adjusted, and it is not necessary to cut and remove asphalt pavement etc. on the connecting road.
[0069]
(D) Since the outer end portion of the pavement member support beam means is supported by the sleeper attachment portion attached to the sleeper, it is not necessary to use a conventional fixing block outside the sleeper.
[0070]
(E) By attaching the sleeper attaching means to the plurality of sleepers, it is possible to prevent the interval between the plurality of sleepers from fluctuating.
