Description

【0001】
【発明の属する技術分野】
本発明は、運動競技用のグラウンド、トラック、コート、ジョギングコース、床等の舗装に使用する弾性舗装材を、短時間に精度良く敷き均しができるレーキに関する。
【0002】
【従来の技術】
グラウンド、トラック、コートなどの屋外運動用施設では、全天候型とするために、ウレタン等の弾性舗装材を使用した地面の舗装が行われており、このような舗装は年々増加してきている。
【0003】
弾性舗装材を使用した地面の舗装において、従来は、押し板に柄をT字形に形成したレーキが使用されており、人手による作業が行われていた。
その作業方法は、まず、コンクリート基盤または下地処理した施工面に、液状ウレタン等に樹脂チップ等の粉体を撹拌させた弾性舗装材を撹拌装置より流し込む。弾性舗装材は粘度が高く、30mm厚程度の島状の固まりとなって施工面を部分的に覆い、全体へは広がらないため、作業者はレーキの柄を持ち、固まりとなった弾性舗装材をレーキの押し板で押すように前進して、8〜10mm厚程度に均して広げていき、まだ弾性舗装材が流れていない施工面へ押し広げながら第1層を形成する。第1層は、運動用施設として一定の弾力性、耐久性を得るために弾性舗装材の厚みを確保するもので、厳密な厚みの精度は不要であり、レーキにより均しを一度行うのみで完了する。
【0004】
そして、第1層が硬化した後、第2層を形成するために弾性舗装材を流し込む。流し込まれた弾性舗装材は、第1層の舗装面上に、30mm厚程度の島状の固まりとなるので、レーキにて8〜10mm厚程度に弾性舗装材の均しを行う。
最後に、再度レーキにて4mm厚に均しを行い、第2層を形成する。
運動用施設の用途によっては、様々な色を使用することがあり、第2層を下地層として2mm厚を形成した後に、上塗り層として着色した弾性舗装材を2mm厚に形成させ、合計4mm厚とする場合もある。
【0005】
この第2層は、前工程の8〜10mm厚程度とする均しから、後工程の2mm厚または4mm厚に仕上げるまで、作業時間が長時間にわたると弾性舗装材が硬化するので、同時に行う必要がある。そのため、前工程の均しを行う作業者と後工程の仕上げを行う作業者の2人が前後に並びながらの同時作業となる。
【0006】
従来の作業方法を図8および図9によりさらに詳しく説明する。
図8は、作業者が施工面の左側から第1層および第2層の均し工程の作業を行う方法を示す図であり、図9は、作業者が施工面の左側から第2層の仕上げ工程を行う方法を示す図である。
【0007】
図8において、まず、施工面60の左側から作業を行う場合は、作業者はレーキの柄を持ち、進行方向に対し押し板の左端部を前に、押し板の右端部を後ろに傾斜させ、弾性舗装材の固まりを押し板にて押すように前進する。弾性舗装材はレーキの進行に伴い施工面60のまだ弾性舗装材を均していない場所S5に向かって流れる(同図(a))。作業者は弾性部材が部分的に厚くならないように広く均す必要があるため、押し板の進行方向に対する傾斜の角度を変えながら場所S5に流れ込んだ弾性舗装材を施工面60のまだ弾性舗装材を均していない場所S6へ押し流す(同図(b))。この作業を繰り返りながら進行方向に対し8〜10mm厚程度に弾性舗装材の均しを行う。
【0008】
このようにして、レーキの押し板を進行方向に対する傾斜の角度を変えながら弾性舗装材を均していき、第1層を形成し、弾性舗装材が硬化した舗装面に第2層を形成するために弾性舗装材を流し込み、同様の方法にて第2層の均し工程を前側の作業者が行う。
【0009】
次に、後側の作業者が仕上げ工程の作業を行う。
第2層の仕上げ工程を行う作業者は、図9に示すように、同様に進行方向に対し押し板の左端部を前に、押し板の右端部を後ろに傾斜させ、押し板の下端と舗装面の隙間を均一にしながら進行する。隙間を均一とすることで、レーキの進行した弾性舗装材の厚みを均一にし、仕上げ面とすることができる。厚みを形成する際の余分な弾性舗装材は、まだ仕上げ面を形成していない施工面60の場所S7へ押し流す。仕上げ面とまだ均しをしていない面との境は、弾性舗装材の厚みに違いがあり、まだ均しを行っていない面の方が仕上げ面より弾性舗装材の厚みが厚いので、均しを行っていない面から弾性舗装材の流れ込みが発生し、作業者が仕上げ面を形成するとともに波を打つような境界線ができる(同図(a))。
【0010】
仕上げ工程では、レーキを進行方向に対し傾斜の角度を変えると、安定した仕上げ面を形成できないので、一定の傾斜の角度を維持しながら蛇行することなく直進して作業を行う。
【0011】
次に、施工面の端まで到達すると、作業者は向きを変え、進行方向に対し押し板の左端部を後ろへ、押し板の右端部を前に傾斜を変更し、仕上げが完了していない面から仕上げ面に流れ込んだ弾性舗装材の境界を押し板の中央部となるように位置して進行し、仕上げを行う。つまり、押し板の1/3〜1/2程度の幅ずつ仕上げ面を重ね合わせて仕上げ面を形成し、余分な弾性舗装材は施工面60のまだ弾性舗装材を均していない場所S8へ押し流す(同図(b))。
【0012】
以上のように、施工面の端から端までの往復を繰り返しながら、1000mの舗装を、第1層を形成するときは1人の作業者が、第2層を形成する場合には2人の作業者が5時間程度要しており、仕上げ工程の作業は、弾性舗装材を均一に精度の良い厚みで仕上げ面を形成する必要があるので、熟練した作業者が作業を行っている。
【0013】
一方、従来の手操作によるレーキとして、例えば特許文献1に記載の定規付きレーキがある。
特許文献1に記載のレーキは、レーキの押し板と調整板を重ねてスライド可能とし、調整板に定規板を固定し、押し板の下端から施工面までの隙間を測り、押し板を垂直方向へスライドさせ隙間を調整することで、施工する際の舗装材の厚みを調整できるようにしたもので、熟練した作業者が不要となるとされている。
【0014】
また、短時間で敷き均しを行うレーキとして、例えば特許文献2に記載の弾性舗装材の施工機械がある。
特許文献2に記載の施工機械は、レーキに高さの調整可能な車輪を備え、レーキをユンボ等で吊るし、レーキに備えた回転用モータで360°回転させながらレーキ支持アームを回転させるようにしたものであり、省力化および施工時間の短縮が図れるとされている。

【特許文献2】
特許第2920031号公報(段落番号0010−0022)
【0016】
【発明が解決しようとする課題】
従来の弾性舗装材を使用した運動用施設の地面舗装においては、第2層を形成するときの均し工程では、広く均す必要があるため、レーキの押し板を進行方向に対し傾斜の角度を変えながら均しを行い、仕上げ工程では、安定した仕上げ面を形成するため、傾斜の角度は変えずに維持する必要があるので、レーキの操作方法が異なり、一度の操作で仕上げ面を形成することができないため、第2層を形成するためには少なくとも2人の作業者が必要であった。
【0017】
また、仕上げが完了していない面から仕上げ面に流れ込んだ弾性舗装材の境界を均すために、押し板の1/3〜1/2程度の幅ずつ仕上げ面を重ね合わせて仕上げ面を形成するため、非常に効率の悪いものとなっていた。
【0018】
特許文献1に記載のレーキを使用した場合は、施工面の仕上げを行う際の厚みの調整は容易に行えるが、やはり、第2層を形成するためには、均し工程では押し板を進行方向に対し傾斜の角度を変えながら作業をし、仕上げ工程では傾斜の角度を一定とする必要があるため、一度の操作で仕上げ面を形成することができない。
また、手操作によるものなので、広い面積の敷き均しをするためには、多大な作業時間を要する。
特許文献2に記載の施工機械を使用した場合は、第1層の作業は大幅な省力化が図れるが、レーキ本体を上から吊り下げるので、ユンボ等の重機が必要であり、またレーキ本体は、回転させるための回転モータ等を備えているため、レーキ本体および車両の総重量が約2t以上となるので、第2層の作業に使用すると、レーキ本体を吊るす重機が第1層に沈み込み跡を付けてしまうため、使用することができず、第2層の作業は人力に頼るしかない。
【0019】
そこで、本発明の目的は、省力化が図れ、短い施工期間で、仕上がり精度が良い弾性舗装材の施工用レーキを提供することにある。
【0020】
【課題を解決するための手段】
本発明の弾性舗装材の施工用レーキは、弾性舗装材料を均一に敷き均しするレーキであって、板状部材をV字形に形成した均し部と、前記均し部の両端部を板状部材に略三角形状となるよう接合した仕上げ部で構成されることを特徴とする。
【0021】
この構成においては、仕上げ部と進行方向に対し傾斜の角度が異なる均し部が、仕上げを行う仕上げ部より前に弾性舗装材を押し流して均しを行う。これにより、均し部は、仕上げ面を形成するに余分な弾性舗装材を押し流し、仕上げ面を形成する適正な量の弾性舗装材を仕上げ部へ流すことができるので、均し部にて第2層の前工程である均しを行いながら、仕上げ部にて第2層の後工程である仕上げを行うため、1人の作業者が前工程と後工程を同時に行うことが可能となる。
【0022】
また、前記均し部と前記仕上げ部に3以上の支持部を備えたほうが望ましい。レーキ本体を支持部が支えるので、安定した敷き均し作業ができる。
支持部は、レーキを支え粘度の高い弾性舗装材の中を進行するのに抵抗が少ない方が良いので、車輪、板状部材、棒状部材、針状部材、三角柱状部材等を用いることができるが、特に支持部としては、幅の細い車輪が望ましい。
支持部の下端を結ぶ仮想面から仕上げ部の下端までが、弾性舗装材を敷き均す際の厚みとなるため、精度の良い厚みを形成することができる。
支持部の下端を結ぶ仮想面とは、新たに弾性舗装材を流し込み、所定の厚みに敷き均しを行い、新しく面を形成する際の基準となる面のことであり、第1層を形成する際には施工面が、第2層を形成する場合には舗装面となる。以下、この面を基準面と称す。
【0023】
また、均し部を均し固定部と均し固定部に対し垂直方向にスライドする均し調整部とで構成することで、均し調整部の下端と基準面の隙間を変えることができる。このため、均し部調整部は、仕上げ面の弾性舗装材の厚みに応じた適正な量の弾性舗装材を均し調整部の下端を通過させて仕上げ部へ流すことができ、余分な弾性舗装材を押し流すことができる。
【0024】
また、仕上げ部を、仕上げ固定部と、仕上げ固定部に垂直方向にスライドする仕上げ調整部とで構成することで、仕上げ固定部の下端と基準面の隙間を変ることができ、仕上げ面の弾性舗装材の厚みを必要に応じて変えることができる。
【0025】
本発明の他の弾性舗装材の施工用レーキは、弾性舗装材料を均一に敷き均しするレーキであって、板状部材をV字形に形成した均し部と、前記均し部の両端部を板状部材に略三角形状となるよう接合した仕上げ部と、前記均し部と前記仕上げ部に3以上の支持部でレーキ本体を構成し、車両と連結するための牽引フレームはスライド機構を介して前記レーキ本体に接続され、前記スライド機構により前記レーキ本体を水平方向にスライドさせることを特徴とする。
【0026】
この構成においては、仕上げ部と進行方向に対し傾斜の角度が異なる均し部が、仕上げを行う仕上げ部より前に弾性舗装材を押し流して均しを行う。これにより、均し部は、仕上げ面を形成するに余分な弾性舗装材を押し流し、仕上げ面を形成する適正な量の弾性舗装材を仕上げ部へ流すことができるので、均し部にて第2層の前工程である均しを行いながら、仕上げ部にて第2層の後工程である仕上げを行え、前工程と後工程を同時できる。
また、牽引フレームを車両に連結し牽引させ敷き均しを行うことで、大幅な施工期間の短縮が図れる。また、牽引フレームは水平方向にスライドさせるスライド機構を介してレーキ本体に接続されているので、レーキ本体を進行方向に対する傾斜の角度を維持したまま、仕上げ部の仕上げ面を水平方向へスライドさせることができる。これにより、作業者が仕上げ面を形成していく上で、仕上げ部が形成する仕上げ面の重ね合わせを最小限とすることができ効率のよい作業ができる。
【0027】
また、均し部の先端部に板状部材の均し補助部を備え、均し補助部は均し部に回動機構を介して接続したことで、均し補助部は、均し部の前部にて均しを行うので、V字形の片側の傾斜面のみで均しをする均し部より幅広く弾性舗装材の均しをすることができる。また、仕上げ部の進行方向に対する傾斜の角度が変っても、均し補助部を回動させ、最適な角度とすることができる。
【0028】
また、均し部を均し固定部と均し固定部に対し垂直方向にスライドする均し調整部とで構成することで、均し調整部の下端と基準面の隙間を変えることができるので、仕上げ面の弾性舗装材の厚みに応じた適正な量の弾性舗装材を均し調整部の下端を通過させて仕上げ部へ流すことができ、余分な弾性舗装材を押し流すことができる。
【0029】
また、仕上げ部を、仕上げ固定部と、仕上げ固定部に垂直方向にスライドする仕上げ調整部とで構成することで、仕上げ固定部の下端と基準面の隙間を変ることができ、仕上げ面の弾性舗装材の厚みを必要に応じて変えることができる。
【0030】
【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。
(実施の形態1)
図1は、本発明の実施形態1に係る弾性舗装材の施工用レーキの斜視図である。
【0031】
図1において、本発明の弾性舗装材の施工用レーキ(以下、「レーキと称す」)1は、矩形板状部材をV字形に形成した均し部2と、矩形板状部材からなる仕上げ部3と、コの字形に形成された操作部4と、支持フレーム5と、車輪6で構成される。
【0032】
均し部2は、均し固定部7と均し調整部8から構成される。均し固定部7と均し調整部8には、均し調整部8を垂直方向にスライドさせ任意の位置で固定するための縦長楕円形の固定穴9を形成し、ボルトを固定穴9に挿通させ座金とナットにて固定する。
均し調整部8は、均し固定部7に対し垂直方向へスライドさせることで、均し調整部8の下端と基準面との隙間を調整できる。これにより、均し調整部8は、仕上げ面の弾性舗装材の厚みに応じた適正な量の弾性舗装材を均し調整部8の下端を通過させ仕上げ部3へ流すことができ、余分な弾性舗装材を押し流すことができる。
【0033】
仕上げ部3は、仕上げ固定部10と仕上げ調整部11から構成される。仕上げ固定部10と仕上げ調整部11には、仕上げ調整部11を垂直方向にスライドさせ任意の位置で固定するための縦長楕円形状の固定穴12を形成し、ボルトを固定穴9に挿通させナットおよび座金等で固定する。
仕上げ調整部11を垂直方向へスライドさせ、仕上げ調整部11の下端と基準面との隙間を調整することで、仕上げ面を形成する弾性舗装材の厚みを調整することができる。
仕上げ固定部10は、均し固定部7の両端部を略三角形状となるよう接合している。
【0034】
仕上げ調整部11の両端部の傾斜部13は、均し部2側にくの字形に形成されており、仕上げ調整部11を進行方向に対して傾斜させて使用する際に、後ろ側となった仕上げ調整部11の端部に流れ込む弾性舗装材を保ち、端部を周り込んで仕上げ調整部11が形成する仕上げ面へ弾性舗装材が流れ込むのを減少させる機能を持つ。
【0035】
操作部4の先端のリング部に支持フレーム5を挿通して回動自在とし、均し固定部7と支持フレーム5とが略三角形を形成するよう接合することで、作業者は操作部4を上下に操作したときに操作部4が回動することで操作性を良くしている。
支持フレーム5は、仕上げ固定部10と均し固定部7とともに、レーキ1の強度を確保している。
【0036】
車輪6は、均し部2の先端部内側に1個と、仕上げ部3の均し部2側に2個備えられ計3個にてレーキ1を支えるので、作業者は、移動の際にレーキ1を持ち上げる必要がなく、操作部4を持ち台車を押すようにして敷き均し作業が行える。仕上げ調整部11の下端と3個の車輪6が当接する面(つまり基準面)の隙間が仕上げ面の厚みとすることができる。
【0037】
次に、図2に基づいて、均し調整部8と仕上げ調整部11の各下端と基準面の隙間を測る方法を説明する。
図2は、隙間を測定する手段を表した図である。
【0038】
仕上げ調整部11の下端が基準面と当接している状態で、仕上げ固定部10の上端を0mmの位置とする目盛を仕上げ調整部11の上部に付ける。仕上げ調整部11を上へスライドさせると、仕上げ固定部10の上端の位置の目盛が、仕上げ調整部11の下端と基準面の隙間Lとなる。固定穴12および目盛を仕上げ部3の両端部の2箇所に設け、2箇所の測定した値を同じとすることで、仕上げ調整部の下端を基準面に対し平行とすることができるので、簡単に正確に仕上げ調整部の隙間を調整することができる。
以上の手段は、仕上げ調整部11の上部目盛と仕上げ固定部10の上端とで隙間を測定したが、仕上げ調整部11の下部に目盛を設け、仕上げ固定部10の下端で隙間を測ることもできる。
また、均し調整部8の下端と基準面の隙間を測る場合でも同様な手段で実現可能である。
均し部2の隙間および仕上げ部3の隙間の調整は、たとえば、第2層の仕上げ面の厚みを4mm厚で行う場合は、仕上げ調整部11の下端と基準面の隙間を4mm、均し調整部8の下端と基準面の隙間を8mmとする。また、第2層の仕上げ面の厚みを2mm厚で行う場合には、仕上げ調整部11の下端と施工面の隙間を2mm、均し調整部8の下端と施工面の隙間を4mmとすることで最適な敷き均しの厚みとすることができる。
つまり、仕上げ調整部11の隙間より、均し調整部8の隙間を大きくし、最適な隙間を仕上げ調整部11と均し調整部8にそれぞれ調整する。そうすることで、均し調整部8は、仕上げの厚みを形成するに要する弾性舗装材を均し調整部8の隙間を通過させて仕上げ調整部11へ流し、余分な弾性舗装材は、仕上げ調整部11で仕上げを行う前に押し流す。そして、仕上げ調整部11は、弾性舗装材の正確な仕上げの厚みを形成することができる。
【0039】
以上の構成において、操作方法を以下に説明する。
図3は、本発明に係る実施形態1の施工方法を表した図である。
【0040】
施工面50の左側から第2層を施工する例とする。
まず、仕上げ調整部11と均し調整部8の隙間の調整を行う。たとえば、第2層を4mm厚で仕上げる場合、仕上げ調整部の隙間を4mmとし、均し調整部8の隙間を8mmに合わせ作業を開始する。
【0041】
次に、施工面50に弾性舗装材を流し込む。弾性舗装材は粘度が高く30mm厚程度の島状の固まりとなって施工面を部分的に覆い、全体へは広がらない。作業者はレーキ1の操作部4を持ち、進行方向に対し仕上げ調整部11の左端部を前に、仕上げ調整部11の右端部を後ろに傾斜させ、弾性舗装材を押すように前進する。均し調整部8の隙間は8mmに調整してあるため、8mm厚より厚い弾性舗装材は、作業者の進行に伴いF1のような流れとなり施工面50のまだ弾性舗装材を均していないS1に向かって流れる。8mm厚以下の部分の弾性舗装材は、均し部調整部8の下端を通過し仕上げ調整部11へ流れる、作業者が進行すると、仕上げ調整部11により、4mm厚の仕上げ面を形成しながら余分な弾性舗装材はF2の流れとなり、施工面50のまだ弾性舗装材を均していないS2に向かって流れる。
【0042】
以上のように、余分な弾性舗装材を均し調整部8により事前に押し流すことで、適正な量の弾性舗装材が仕上げ調整部11へ流れる。これにより均し調整部8にて前工程である弾性部材の均しを行いながら、仕上げ調整部11にて後工程である仕上げを行うため、前工程と後工程を同時に行うことが可能となる。
【0043】
(実施の形態2)
図4は、本発明の実施形態2に係るレーキの斜視図である。
【0044】
図4において、本発明の弾性舗装材の施工用レーキ20は、レーキ本体23と、均し補助部22と、牽引フレーム28と、牽引フレーム28とレーキ本体23を接続するスライド機構26とで構成されている。
レーキ本体23は、矩形板状部材をV字形に形成した均し部21と、矩形板状部材に仕上げ部34と、仕上げ部34と均し部21に備えた3個の車輪38と、支持フレーム29とで構成されている。
【0045】
均し部21は、均し固定部30と均し調整部31で構成される。均し固定部30と均し調整部31には、均し調整部をスライドさせ任意の位置で固定するための縦長楕円形の固定穴32を形成し、ボルトを固定穴32に挿通させ座金とナットにて固定する。
均し調整部31は、均し固定部30に対し垂直方向へスライドさせることで、均し調整部31の下端と基準面との隙間を調整できる。これにより均し調整部31は、仕上げ面の弾性舗装材の厚みに応じた適正な量の弾性舗装材を均し調整部31の下端を通過させ仕上げ部34へ流すことができ、余分な弾性舗装材を押し流すことができる。
【0046】
仕上げ部34は、矩形の板で形成され、仕上げ固定部35と仕上げ調整部36から構成されている。
仕上げ固定部35と仕上げ調整部36には、仕上げ調整部をスライドさせ任意の位置で固定するための縦長楕円形状の固定穴37を形成し、ボルトを固定穴37に挿通させナットおよび座金等で固定する。
仕上げ固定部35は、均し固定部30の両端部を略三角形状となるよう接合している。
仕上げ調整部34は、仕上げ固定部30に対し垂直方向へスライドさせ、仕上げ調整部34の下端と基準面との隙間を調整することで、仕上げ面を形成する弾性舗装材の厚みを調整することができる。
仕上げ調整部36の垂直方向の幅は、仕上げ調整部36を上へスライドさせ、仕上げ面を形成する弾性舗装材の厚みを最大とした場合でも、仕上げ調整部36の上端がスライド機構26に当接しない程度の幅としている。
また、仕上げ調整部36の両端部の傾斜部47は、均し部21側にくの字形に形成されている。
【0047】
車輪38は、均し部21の内側に1個と、仕上げ部34の均し部21側に2個備えられ計3個にてレーキ本体23を支えている。
【0048】
支持フレーム29は、棒状部材をH字形に形成し、均し固定部30と仕上げ固定部35に接合しており、均し固定部30と仕上げ固定部35とともに、レーキ20の強度を確保している。
【0049】
均し補助部22は、矩形の板で形成され、均し部21の先端部に回動機構を介して接続されており、均し補助部22は支持フレーム29と油圧シリンダ33で連結され、油圧シリンダ33の伸縮により、均し補助部22を回動させる。
油圧シリンダ33を進行方向に対し均し補助板22の右端部に接続した場合では、油圧シリンダ33が伸長すると、均し補助部22の右端部が前へ、左端部が後ろへ傾斜し、油圧シリンダ33が収縮すると、均し補助部22の右端部が後ろへ、左端部が前へ傾斜する。
また、車輪27を均し補助部22の両端部に備えており、回動の際に均し補助部22の動作を安定させる。
【0050】
牽引フレーム28は、枠部43と連結部44とサスペンション45で構成され、車両等で牽引する際には、車両側の牽引リンク等に枠部43の牽引部43aとサスペンション45を連結し、水平方向は固定されているが、垂直方向の上下は回動自在であり、サスペンション45を連結することで車両等の牽引時の振動を緩和し、垂直方向の上下に対する振動の安定性が良くなる。
【0051】
スライド機構部26は、ガイドレール39と、駆動板40と、連結棒41と、仕上げ固定部35の上部に水平に接合した矩形の板の摺動部25と、摺動部25とガイドレール39に接続された油圧シリンダ42で構成される。
【0052】
摺動部25が仕上げ固定部35の上部に水平に接合し断面がT字形となるように形成され、断面が略コの字形に形成したガイドレール39の内部を摺動しスライドする。
【0053】
ガイドレール39は、油圧シリンダ42を介して摺動部25に接続しており、伸縮することで、牽引フレーム28が水平方向に固定されているため、レーキ本体23が水平方向にスライドする。
油圧シリンダ42を進行方向に対し駆動板40の右端部およびガイドレール39の右端部に接続した場合、油圧シリンダ42を伸長すると、レーキ本体23が左側へスライドし、収縮するとレーキ本体23が右側へスライドする。
【0054】
連結棒41は、駆動板40に接合され、連結部44を挿通しており、回動可能であり、垂直方向にも摺動可能である。連結部44の上部および下部に付勢部材を介して連結棒44と接続することで、車両等で牽引する際に発生する車両の垂直方向の上下振動を緩和し、レーキ本体23に伝達することを防止している。
【0055】
枠部43は、スライド機構部26の駆動板40と油圧シリンダ46で接続されており、伸縮することで、レーキ本体23の傾斜方向を変更することができる。
【0056】
油圧シリンダ46を進行方向に対し駆動板40の右端部に接続した場合、油圧シリンダ46を伸長すると、進行方向に対しレーキ本体23の右端部が後ろ、左端部が前へ傾斜し、収縮すると、レーキ本体23の右端部が前へ、左端部が後ろ傾斜する。
【0057】
以上の構成において、操作方法を以下に説明する。
図5は、本発明に係る実施形態の2の施工方法を表した図である。
【0058】
施工面51の左側から第2層を施工する例である。
まず、仕上げ調整部36と均し調整部31の隙間の調整を行う。例えば、第2層を4mm厚で仕上げる場合、仕上げ調整部の隙間を4mmとし、均し調整部31の隙間を8mmに合わせ、均し補助部22は15mm固定とし、作業を行う。
【0059】
作業者は、牽引フレーム28の油圧シリンダ46を伸長させ、進行方向に対しレーキ本体23の左端部を前に、右端部を後ろに傾斜させる。また、作業者は油圧シリンダ33を伸長させ、均し補助部22の回動機構を中心として、左端部を後ろに、右端部を前に傾斜させる。
【0060】
作業者は、車両に乗車し前進することで、弾性舗装材をかき寄せるように敷き均しを始める。均し補助部22は、隙間の調整が15mmであるため、15mmより盛り上がっている弾性舗装材を押し流す。そうすると、弾性舗装材は、F3で示される流れになり、施工面51のまだ弾性舗装材を均していないS3に流れる。15mm厚以下の弾性舗装材は、均し補助部22の下端を通過し均し調整部31に流れる。均し調整部31は、隙間の調整が8mmであるため、8mm厚より厚い弾性舗装材を押し流し、均し補助部22の流れ同様にF3の流れとなり、S3へ流れる。
【0061】
8mm厚以下の弾性舗装材は、均し調整部31の下端を通過し仕上げ調整部36へ流れる。仕上げ調整部は、隙間の調整が4mmであるため、4mm厚より厚い余分な弾性舗装材を押し流し、F4の流れとなり、まだ弾性舗装材を均していない領域S4へ流れ、4mm厚以下の弾性舗装材は、仕上げ調整部36の下端を通過し、仕上げ面を形成する。
【0062】
舗装面の端まで到達すると、作業者は向きを変え、作業者は牽引フレーム28の油圧シリンダ46を収縮させ、進行方向に対しレーキ本体23の左端部を後ろに、右端部を前に傾斜させ、均し補助部22を、油圧シリンダ33を収縮させ、回動機構を中心として、左端部を前に、右端部を後ろに傾斜させ、車両を前進して、同様に作業を行う。
【0063】
以上のように、均し補助部22が均し調整部31の前部にて均しを行うため、V字形の片側の傾斜面のみで均しをする均し部21より、幅広く弾性舗装材の均しをすることができる。また、レーキ本体23の傾斜の角度が変っても、油圧シリンダ46を伸縮させることで、均し補助部22を回動させ、最適な角度とすることができる。
【0064】
図6は、本発明の実施形態2に係るスライド機構を使用した施工方法を表した図である。
舗装面52の左側から第2層を施工する例とする。
作業者は、進行方向に対しレーキ本体23の左端部を前に、右端部を後ろに傾斜させ、均し補助部22を回動機構を中心として、左端部を後ろに、右端部を前に傾斜させる。
そして、仕上げが完了していない面から仕上げ面に対し弾性舗装材の厚みの違いによる打つような境界Wを、進行方向に対しレーキ本体23の左端に位置するようにして仕上げ面を形成する。
境界Wは、場所によってレーキ本体23が仕上げ面を形成する幅より進行方向に対し左方へ外れていることがある。この場合、進行しながらスライド機構26の油圧シリンダ42を収縮させる。スライド機構部26は、牽引フレーム28を介して車両に連結しており、横方向は固定されているため、油圧シリンダ42を収縮することで、摺動部25がスライド機構26内を摺動して、レーキ本体23が左側にスライドし、境界Wに対して、レーキ本体23の傾斜角度を変えることなく、弾性舗装材の敷き均しを行うことができる。
これにより、レーキ本体が形成する仕上げ面の重ね合わせを最小限とすることができ効率のよい作業ができる。また、レーキ本体23の傾斜の角度を変える必要がないため、牽引する車両を左右にハンドルを切りながら蛇行するような運転をしなくてよいので、安定した作業ができる。
【0065】
以上の本発明の実施形態2のレーキを、車両48で牽引した例を図7に示す。
図7は、車両で牽引するレーキの外観斜視図である。
【0066】
作業者は車両48に乗車してレーキ20から、車両48側の牽引リンク等に枠部43の牽引部43aとサスペンション45を連結し牽引し敷き均し作業を行う。
油圧シリンダ33、42、46は、牽引する車両48から操作することで、均し補助部22、仕上げ調整部36の回動の制御やスライド機構26のスライドの制御を行えるので、状況に応じた敷き均し作業が可能となる。
【0067】
仕上げ部および均し補助部のスライドまたは回動させる手段は、油圧シリンダ等で実現可能なため、回転モータ等の重量物が必要なく、またレーキを牽引して敷き均しを行うため、車両も小型のものが使用でき、レーキおよび車両の総重量も300Kg以内と軽いものとすることができるので、第1層のみならず第2層作業を行うことができる。
【0068】
【実施例】
(実施例1)
第1の実施の形態の弾性舗装材の施工用レーキを使用して運動施設の施工を行った。
均し部を450mm、仕上げ部を1000mm、仕上げ部の各端部から100mmの位置を角度145°で曲げ、均し部と仕上げ部の接合角度を35°でレーキを製作し、弾性舗装材として主剤と硬化剤を1:1の割合で混合したものを使用し、舗装面1000mの第2層の施工を行った。
隙間の調整は、均し部の隙間を8mm、仕上げ部の隙間を4mmとした。
結果、弾性舗装材の敷き均しおよび仕上げを、従来では、2人の作業者が5時間を要していたところを、1人の作業者が5時間で行うことができ、第2層表面の仕上げも、4.0±0.2mmと良好であった。
【0069】
(実施例2)
均し部を800mm、均し補助部を1000mm、仕上げ部を2000mm、仕上げ部の各端部から200mmの位置を角度145°で曲げ、均し部と仕上げ部の接合角度を35°でレーキを製作し、弾性舗装材として主剤と硬化剤を1:1の割合で混合したものを使用し、舗装面1000mの第2層の施工を車両で牽引して行った。
隙間の調整は、均し補助部の隙間を15mm、均し部の隙間を8mm、仕上げ部の隙間を4mmとした。
結果、弾性舗装材の敷き均しおよび仕上げを、1人の作業者が2時間で行うことができ、第2層表面の仕上げも4.0±0.2mmと良好であった。

【0071】
(1)仕上げ部と進行方向に対し傾斜の角度が異なる均し部が、仕上げを行う仕上げ部より前に弾性舗装材を押し流し、均しを行う。これにより、均し部は、仕上げ面を形成するに余分な弾性舗装材を押し流し、仕上げ面を形成する適正な量の弾性舗装材を仕上げ部へ流すことができるので、均し部にて第2層の前工程である均しを行いながら、仕上げ部にて第2層の後工程である仕上げを行うため、1人の作業者が前工程と後工程を同時に行うことが可能となり、弾性舗装材の敷き均し作業が省力化図れる。
【0072】
(2)レーキ本体を支持部が支えるので、安定した敷き均し作業ができる。また、支持部の下端を結ぶ仮想面から仕上げ部の下端までが、弾性舗装材を敷き均す際の厚みとなるため、精度の良い厚みを形成することができる。

【0074】
(4)仕上げ固定部の下端と基準面の隙間を変ることができ、仕上げ面を形成するに必要な弾性舗装材の厚みとすることができるので、様々な運動施設に応じた仕上げ面の厚みを精度よく形成することができる。
【0075】
(5)仕上げ部と進行方向に対し傾斜の角度が異なる均し部が、仕上げを行う仕上げ部より前に弾性舗装材を押し流して、均しを行う。これにより、仕上げ面を形成するに余分な弾性舗装材を押し流し、仕上げ面を形成する適正な量の弾性舗装材を仕上げ部へ流すことができるので、均し部にて第2層の前工程である弾性舗装材の均しを行いながら、仕上げ部にて第2層の後工程である仕上げを行え、前工程と後工程を同時できる。また、牽引フレームを車両に連結し牽引させることで、大幅に施工期間の短縮が図れる。

また、仕上げ部の傾斜の角度を変える必要がないため、牽引する車両を左右にハンドルを切りながら蛇行するような運転をしなくてよいので、安定した敷き均し作業ができる。
【0076】
(6)均し補助部は、均し部の先端部にて均しを行うため、V字形の片側の傾斜面のみで均しをする均し部より幅広く均しをすることができる。また、均し補助部を回動させることで、仕上げ部の進行方向に対する傾斜の角度が変っても、最適な角度とすることができ、より効率の良い敷き均し作業が可能となる。
【0077】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rake capable of accurately and quickly laying an elastic pavement material used for paving an athletic field such as a ground, a track, a court, a jogging course, and a floor.
[0002]
[Prior art]
In outdoor sports facilities such as a ground, a track, and a court, the ground is paved with an elastic pavement material such as urethane in order to provide an all-weather type, and such paving is increasing year by year.
[0003]
Conventionally, in pavement on the ground using an elastic pavement material, a rake in which a handle is formed in a T-shape on a push plate has been used, and manual work has been performed.
The working method is as follows. First, an elastic pavement material in which powder such as resin chips is stirred in liquid urethane or the like is poured from a stirrer into a concrete base or a ground surface. The elastic pavement material has a high viscosity and forms an island-like lump with a thickness of about 30 mm that partially covers the construction surface and does not spread over the entire surface. Is pushed forward with a push plate of the rake, and is spread evenly to a thickness of about 8 to 10 mm. The first layer is formed while being spread on a construction surface on which the elastic pavement material has not flowed yet. The first layer secures the thickness of the elastic pavement material to obtain a certain elasticity and durability as an exercise facility, and precise thickness accuracy is not required. Complete.
[0004]
Then, after the first layer is hardened, an elastic pavement material is poured to form the second layer. Since the poured elastic pavement material becomes an island-like lump having a thickness of about 30 mm on the pavement surface of the first layer, the elastic pavement material is leveled by a rake to a thickness of about 8 to 10 mm.
Finally, the layer is leveled again with a rake to a thickness of 4 mm to form a second layer.
Depending on the purpose of the sports facility, various colors may be used. After forming the second layer as a base layer and forming a 2 mm thickness, a colored elastic pavement material is formed as a top coat layer to a thickness of 2 mm and a total of 4 mm thickness In some cases,
[0005]
This second layer is required to be performed at the same time since the elastic pavement material is hardened when the working time is long, from the leveling of about 8 to 10 mm thickness in the previous step to the finishing of 2 mm or 4 mm thickness in the subsequent step. There is. For this reason, two workers, a worker performing leveling in the previous process and a worker performing finishing in the post-process, are simultaneously operated while being arranged in front and rear.
[0006]
The conventional working method will be described in more detail with reference to FIGS.
FIG. 8 is a diagram illustrating a method in which the worker performs the work of the leveling process of the first layer and the second layer from the left side of the construction surface, and FIG. It is a figure showing the method of performing a finishing process.
[0007]
In FIG. 8, first, when working from the left side of the construction surface 60, the worker holds the handle of the rake and leans the left end of the push plate forward and the right end of the push plate backward with respect to the traveling direction. Then, it advances so that the mass of the elastic pavement material is pushed by the push plate. The elastic pavement flows toward the place S5 on the construction surface 60 where the elastic pavement has not yet been leveled with the progress of the rake (FIG. 7A). Since the operator needs to level the elastic member widely so as not to be partially thickened, the elastic pavement material flowing into the place S5 while changing the inclination angle with respect to the traveling direction of the push plate is still elastic pavement material on the construction surface 60. Is flushed to a non-uniform place S6 (FIG. 9B). While repeating this operation, the elastic pavement material is leveled to a thickness of about 8 to 10 mm in the traveling direction.
[0008]
In this manner, the elastic pavement material is leveled while changing the angle of inclination of the push plate of the rake with respect to the traveling direction to form the first layer, and the second layer is formed on the hardened pavement surface of the elastic pavement material. For this purpose, an elastic pavement material is poured in, and the leveling process of the second layer is performed by a worker on the front side in the same manner.
[0009]
Next, the worker on the rear side performs the work of the finishing process.
As shown in FIG. 9, the worker performing the finishing process of the second layer similarly tilts the left end of the push plate forward and the right end of the push plate backward with respect to the traveling direction, and It progresses while making the gap on the pavement surface uniform. By making the gaps uniform, the thickness of the elastic pavement material on which the rake has advanced can be made uniform and a finished surface can be obtained. Excessive elastic pavement material at the time of forming the thickness is flushed to the place S7 of the construction surface 60 on which the finished surface has not yet been formed. At the boundary between the finished surface and the unleveled surface, there is a difference in the thickness of the elastic pavement material.The thickness of the elastic pavement material is greater on the unleveled surface than on the finished surface. The inflow of the elastic pavement material occurs from the surface on which the work is not performed, and a boundary line is formed in which the worker forms a finished surface and undulates (FIG. 7A).
[0010]
In the finishing step, if the angle of inclination of the rake with respect to the traveling direction is changed, a stable finished surface cannot be formed. Therefore, the work is performed while traveling straight without meandering while maintaining a constant angle of inclination.
[0011]
Next, when reaching the edge of the construction surface, the worker changes the direction, changes the inclination with the left end of the push plate backward and the right end of the push plate forward with respect to the traveling direction, and finishing is not completed Finishing is performed by proceeding with the boundary of the elastic pavement material flowing from the surface to the finished surface positioned at the center of the push plate. In other words, the finished surface is formed by overlapping the finished surfaces by about 1/3 to 1/2 of the width of the pressing plate, and the surplus elastic pavement material is transferred to the place S8 on the construction surface 60 where the elastic pavement material is not yet leveled. It is flushed away (FIG. 2 (b)).
[0012]
As described above, while repeating the reciprocation from one end of the construction surface to the other end, 1000 m 2 When the first layer is formed, one worker takes about 5 hours, and when the second layer is formed, two workers take about 5 hours. Since it is necessary to form a finished surface of the material uniformly and with a high precision, a skilled worker works.
[0013]
On the other hand, as a conventional manual rake, there is a rake with a ruler described in Patent Document 1, for example.
In the rake described in Patent Document 1, the push plate of the rake and the adjusting plate are overlapped and slidable, a ruler plate is fixed to the adjusting plate, a gap from the lower end of the push plate to the construction surface is measured, and the push plate is vertically moved. By adjusting the gap by sliding the pavement, the thickness of the paving material at the time of construction can be adjusted, and it is said that a skilled worker is unnecessary.
[0014]
As a rake that spreads and spreads in a short time, there is, for example, a construction machine for an elastic pavement material described in Patent Document 2.
The construction machine described in Patent Literature 2 is provided with wheels whose height can be adjusted on a rake, suspends the rake with a yumbo or the like, and rotates the rake support arm while rotating 360 ° with a rotation motor provided on the rake. It is said that labor can be saved and construction time can be shortened.

[Patent Document 2]
Japanese Patent No. 2920031 (paragraph number 0010-0022)
[0016]
[Problems to be solved by the invention]
In the ground pavement of an exercise facility using a conventional elastic pavement material, in the leveling process when forming the second layer, it is necessary to level the surface widely, so that the push plate of the rake is inclined at an angle to the traveling direction. In order to form a stable finished surface in the finishing process, it is necessary to maintain the inclination angle without changing, so the rake operation method is different, and the finished surface is formed by one operation As a result, at least two workers were required to form the second layer.
[0017]
In addition, in order to equalize the boundary of the elastic pavement material that has flowed into the finished surface from the surface that has not been finished, the finished surface is formed by overlapping the finished surface by about 1/3 to 1/2 the width of the push plate. Therefore, it was very inefficient.
[0018]
When the rake described in Patent Literature 1 is used, the thickness can be easily adjusted when finishing the construction surface. However, in order to form the second layer, the push plate is advanced in the leveling process. It is necessary to work while changing the inclination angle with respect to the direction, and it is necessary to keep the inclination angle constant in the finishing step, so that a finished surface cannot be formed by a single operation.
Also, since it is a manual operation, a large amount of work time is required to spread a large area.
When the construction machine described in Patent Literature 2 is used, the work of the first layer can greatly reduce labor, but since the rake body is suspended from above, a heavy machine such as a yumbo is required. Since the rake body and the vehicle have a total weight of about 2 tons or more due to the provision of a rotation motor for rotating the rake body, when used for the work of the second layer, the heavy equipment for suspending the rake body sinks into the first layer. Since it leaves a mark, it cannot be used, and the work of the second layer must rely on human power.
[0019]
Then, an object of the present invention is to provide a rake for construction of an elastic pavement material which can save labor, has a short construction period, and has a good finish accuracy.
[0020]
[Means for Solving the Problems]
The rake for construction of an elastic pavement material according to the present invention is a rake in which an elastic pavement material is uniformly spread and leveled, and a flattened portion in which a plate-like member is formed in a V-shape, and both ends of the flattened portion are formed by plate. It is characterized by being constituted by a finished part joined to the shape member so as to have a substantially triangular shape.
[0021]
In this configuration, the leveling section having a different inclination angle with respect to the finishing section and the traveling direction flushes the elastic pavement material before the finishing section to perform the leveling, thereby performing leveling. With this, the leveling section can push away excess elastic pavement material to form the finished surface, and can flow an appropriate amount of elastic pavement material to form the finished surface to the finishing section. Since finishing, which is a post-process of the second layer, is performed in the finishing unit while performing leveling, which is a pre-process of the two layers, one worker can simultaneously perform the pre-process and the post-process.
[0022]
Further, it is desirable to provide three or more support portions in the leveling portion and the finishing portion. Since the rake body is supported by the support, stable laying work can be performed.
Since the supporting portion should have less resistance to support the rake and travel through the high-viscosity elastic pavement material, it is possible to use wheels, plate members, rod members, needle members, triangular prism members, and the like. However, a thin wheel is particularly desirable as the support.
The thickness from the imaginary plane connecting the lower ends of the support portions to the lower end of the finishing portion is the thickness when the elastic pavement material is laid, so that a highly accurate thickness can be formed.
The virtual surface connecting the lower ends of the support portions is a surface that becomes a reference when a new elastic pavement material is poured and spread to a predetermined thickness to form a new surface, and the first layer is formed. When the second layer is formed, the construction surface is a pavement surface. Hereinafter, this surface is referred to as a reference surface.
[0023]
In addition, the gap between the lower end of the leveling adjustment unit and the reference plane can be changed by configuring the leveling unit with the leveling / fixing unit and the leveling adjustment unit that slides in the direction perpendicular to the leveling / fixing unit. For this reason, the leveling section adjusting section can flow an appropriate amount of elastic pavement material according to the thickness of the elastic pavement material on the finished surface to the finishing section by passing the lower end of the leveling adjusting section to the extra elasticity. Paving material can be washed away.
[0024]
In addition, by configuring the finishing part with a finishing fixing part and a finishing adjusting part that slides vertically to the finishing fixing part, the gap between the lower end of the finishing fixing part and the reference surface can be changed, and the elasticity of the finishing surface can be changed. The thickness of the paving material can be varied as needed.
[0025]
Another rake for construction of an elastic pavement material of the present invention is a rake in which an elastic pavement material is evenly spread and leveled, and a leveling portion in which a plate-like member is formed in a V shape, and both ends of the leveling portion. A rake body is composed of a finished part joined to a plate-like member so as to have a substantially triangular shape, and three or more supporting parts on the leveling part and the finished part, and a traction frame for connecting to a vehicle has a slide mechanism. The rake body is slid in the horizontal direction by the slide mechanism.
[0026]
In this configuration, the leveling section having a different inclination angle with respect to the finishing section and the traveling direction flushes the elastic pavement material before the finishing section to perform the leveling, thereby performing leveling. With this, the leveling section can push away excess elastic pavement material to form the finished surface, and can flow an appropriate amount of elastic pavement material to form the finished surface to the finishing section. The finishing, which is the post-process of the second layer, can be performed in the finishing unit while the leveling, which is the pre-process of the two layers, is performed, and the pre-process and the post-process can be performed simultaneously.
Also, by connecting the towing frame to the vehicle and towing and leveling, the construction period can be significantly reduced. In addition, since the towing frame is connected to the rake body via a slide mechanism that slides in the horizontal direction, the finished surface of the finishing unit can be slid horizontally while maintaining the angle of inclination of the rake body with respect to the traveling direction. Can be. Thereby, when an operator forms a finished surface, the overlapping of the finished surfaces formed by the finished portions can be minimized, and efficient work can be performed.
[0027]
In addition, the leveling assist section is provided with a leveling auxiliary section of the plate-shaped member at the tip end of the leveling section. Since the leveling is performed at the front part, the elastic pavement material can be leveled more widely than the leveling part that leveles with only one V-shaped inclined surface. Further, even if the angle of inclination of the finishing section with respect to the traveling direction changes, the leveling assisting section can be rotated to an optimum angle.
[0028]
In addition, since the leveling section is composed of the leveling fixing section and the leveling adjustment section that slides in a direction perpendicular to the leveling fixing section, the gap between the lower end of the leveling adjustment section and the reference plane can be changed. In addition, an appropriate amount of the elastic pavement material according to the thickness of the elastic pavement material on the finished surface can flow through the lower end of the leveling unit to the finishing unit, and excess elastic pavement material can be pushed away.
[0029]
In addition, by configuring the finishing part with a finishing fixing part and a finishing adjusting part that slides vertically to the finishing fixing part, the gap between the lower end of the finishing fixing part and the reference surface can be changed, and the elasticity of the finishing surface can be changed. The thickness of the paving material can be varied as needed.
[0030]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a perspective view of a rake for construction of an elastic pavement material according to Embodiment 1 of the present invention.
[0031]
In FIG. 1, a rake (hereinafter, referred to as a "rake") 1 for constructing an elastic pavement material of the present invention includes a leveling portion 2 in which a rectangular plate-like member is formed in a V-shape, and a finishing portion composed of a rectangular plate-like member. 3, an operation unit 4 formed in a U-shape, a support frame 5, and wheels 6.
[0032]
The leveling unit 2 includes a leveling fixing unit 7 and a leveling adjustment unit 8. In the leveling fixing part 7 and the leveling adjustment part 8, a vertically long elliptical fixing hole 9 for sliding the leveling adjustment part 8 in the vertical direction and fixing at an arbitrary position is formed. Insert and secure with washers and nuts.
The leveling adjustment unit 8 can adjust the gap between the lower end of the leveling adjustment unit 8 and the reference plane by sliding in the vertical direction with respect to the leveling fixing unit 7. Thereby, the leveling adjustment unit 8 can flow an appropriate amount of the elastic pavement material according to the thickness of the elastic pavement material on the finished surface through the lower end of the leveling adjustment unit 8 to the finishing unit 3, and an extra amount can be obtained. The elastic pavement can be washed away.
[0033]
The finishing unit 3 includes a finishing fixing unit 10 and a finishing adjusting unit 11. The finishing fixing unit 10 and the finishing adjusting unit 11 are formed with a vertically elongated elliptical fixing hole 12 for sliding the finishing adjusting unit 11 in a vertical direction and fixing the finishing adjusting unit 11 at an arbitrary position. And secure it with washers.
The thickness of the elastic pavement material forming the finished surface can be adjusted by sliding the finish adjusting unit 11 in the vertical direction and adjusting the gap between the lower end of the finish adjusting unit 11 and the reference surface.
The finishing fixing part 10 is joined so that both ends of the leveling fixing part 7 have a substantially triangular shape.
[0034]
The inclined portions 13 at both ends of the finishing adjustment portion 11 are formed in a V-shape on the leveling portion 2 side, and when the finishing adjusting portion 11 is used with being inclined with respect to the traveling direction, it becomes the rear side. It has a function of keeping the elastic pavement material flowing into the end portion of the finished adjustment portion 11 and reducing the flow of the elastic pavement material around the end portion to the finished surface formed by the finish adjustment portion 11.
[0035]
The operator inserts the support frame 5 into the ring portion at the tip of the operation unit 4 so as to be rotatable, and joins the leveling fixing unit 7 and the support frame 5 so as to form a substantially triangular shape. The operability is improved by rotating the operation unit 4 when operating up and down.

There is no need to lift the rake 1, and the leveling work can be performed by holding the operation unit 4 and pushing the trolley. The gap between the lower end of the finishing adjustment unit 11 and the surface where the three wheels 6 abut (that is, the reference surface) can be the thickness of the finishing surface.
[0037]
Next, a method of measuring the gap between each lower end of the leveling adjustment unit 8 and the finish adjustment unit 11 and the reference plane will be described with reference to FIG.
FIG. 2 is a diagram showing a unit for measuring a gap.
[0038]
With the lower end of the finish adjustment unit 11 in contact with the reference plane, a scale is set on the upper part of the finish adjustment unit 11 so that the upper end of the finish fixing unit 10 is located at 0 mm. When the finish adjustment unit 11 is slid upward, the scale at the upper end of the finish fixing unit 10 becomes the gap L between the lower end of the finish adjustment unit 11 and the reference plane. Since the fixing hole 12 and the scale are provided at two places at both ends of the finishing part 3 and the measured values at the two places are the same, the lower end of the finishing adjustment part can be made parallel to the reference plane, so that it is simple. It is possible to accurately adjust the gap of the finishing adjustment section.
Although the above-described means measures the gap between the upper scale of the finish adjustment unit 11 and the upper end of the finish fixing unit 10, a scale may be provided at the lower part of the finish adjustment unit 11 and the gap may be measured at the lower end of the finish fixing unit 10. it can.
Also, the same means can be used to measure the gap between the lower end of the leveling adjustment unit 8 and the reference plane.
The gap between the leveling unit 2 and the finish unit 3 is adjusted, for example, when the thickness of the finished surface of the second layer is 4 mm, the gap between the lower end of the finish adjusting unit 11 and the reference surface is 4 mm. The gap between the lower end of the adjustment unit 8 and the reference plane is 8 mm. When the thickness of the finished surface of the second layer is 2 mm, the gap between the lower end of the finishing adjustment unit 11 and the construction surface is 2 mm, and the gap between the lower end of the leveling adjustment unit 8 and the construction surface is 4 mm. Thus, the optimum leveling thickness can be obtained.
That is, the gap of the leveling adjustment unit 8 is made larger than the gap of the finish adjustment unit 11, and the optimum gap is adjusted by the finishing adjustment unit 11 and the leveling adjustment unit 8, respectively. By doing so, the leveling adjustment unit 8 allows the elastic pavement material required for forming the finish thickness to flow through the gap of the leveling adjustment unit 8 to the finish adjustment unit 11, and the excess elastic pavement material is finished. It is washed away before finishing in the adjusting unit 11. And the finishing adjustment part 11 can form the accurate finishing thickness of the elastic pavement material.
[0039]
In the above configuration, an operation method will be described below.
FIG. 3 is a diagram illustrating a construction method according to the first embodiment of the present invention.
[0040]
It is assumed that the second layer is constructed from the left side of the construction surface 50.
First, the gap between the finishing adjustment unit 11 and the leveling adjustment unit 8 is adjusted. For example, when finishing the second layer with a thickness of 4 mm, the gap of the finishing adjustment unit is set to 4 mm, and the gap of the leveling adjustment unit 8 is adjusted to 8 mm to start the operation.
[0041]
Next, an elastic pavement material is poured into the construction surface 50. The elastic pavement material has a high viscosity and forms an island-like lump having a thickness of about 30 mm, partially covers the construction surface, and does not spread over the entire surface. The operator holds the operation unit 4 of the rake 1, inclines the left end of the finishing adjustment unit 11 forward and the right end of the finishing adjustment unit 11 backward with respect to the traveling direction, and moves forward so as to push the elastic pavement material. Since the gap of the leveling adjustment unit 8 is adjusted to 8 mm, the elastic pavement material thicker than 8 mm becomes a flow like F1 with the progress of the worker, and the elastic pavement material on the construction surface 50 is not leveled yet. It flows toward S1. The elastic pavement material of the portion having a thickness of 8 mm or less passes through the lower end of the leveling portion adjusting portion 8 and flows to the finishing adjusting portion 11. As the worker advances, the finishing adjusting portion 11 forms a 4 mm thick finished surface. The surplus elastic pavement flows into F2, and flows toward S2 on the construction surface 50 where the elastic pavement has not yet been leveled.
[0042]
As described above, an appropriate amount of the elastic pavement material flows to the finish adjustment unit 11 by flushing the excess elastic pavement material in advance by the leveling adjustment unit 8. Thereby, while the leveling adjustment unit 8 performs the leveling of the elastic member, which is the previous step, and the finishing adjustment unit 11 performs the finishing, which is the post-step, it is possible to perform the pre-step and the post-step simultaneously. .

[0053]
The guide rail 39 is connected to the sliding portion 25 via the hydraulic cylinder 42. Since the towing frame 28 is fixed in the horizontal direction by expanding and contracting, the rake body 23 slides in the horizontal direction.
When the hydraulic cylinder 42 is connected to the right end of the drive plate 40 and the right end of the guide rail 39 in the traveling direction, when the hydraulic cylinder 42 is extended, the rake body 23 slides to the left, and when it contracts, the rake body 23 moves to the right. Slide.
[0054]

[0055]
The frame part 43 is connected to the drive plate 40 of the slide mechanism part 26 by a hydraulic cylinder 46, and can change the inclination direction of the rake body 23 by expanding and contracting.
[0056]
When the hydraulic cylinder 46 is connected to the right end of the drive plate 40 with respect to the traveling direction, when the hydraulic cylinder 46 is extended, the right end of the rake body 23 is inclined rearward and the left end is inclined forward with respect to the traveling direction, and when contracted, The right end of the rake body 23 is inclined forward and the left end is inclined backward.
[0057]
In the above configuration, an operation method will be described below.
FIG. 5 is a diagram illustrating a construction method according to a second embodiment of the present invention.
[0058]
This is an example in which the second layer is constructed from the left side of the construction surface 51.
First, the gap between the finishing adjustment unit 36 and the leveling adjustment unit 31 is adjusted. For example, when finishing the second layer with a thickness of 4 mm, the gap of the finishing adjustment section is set to 4 mm, the gap of the leveling adjustment section 31 is adjusted to 8 mm, and the leveling auxiliary section 22 is fixed at 15 mm.
[0059]
The operator extends the hydraulic cylinder 46 of the towing frame 28 and inclines the left end of the rake main body 23 forward and the right end thereof rearward with respect to the traveling direction. Further, the operator extends the hydraulic cylinder 33 and inclines the left end part backward and the right end part forward with the rotation mechanism of the leveling assist unit 22 as a center.
[0060]
The operator gets on the vehicle and moves forward to start spreading and leveling the elastic pavement material. Since the adjustment of the gap is 15 mm, the leveling assisting section 22 pushes away the elastic pavement material rising from 15 mm. Then, the elastic pavement material flows as indicated by F3, and flows to S3 on the construction surface 51 where the elastic pavement material has not yet been leveled. The elastic pavement material having a thickness of 15 mm or less passes through the lower end of the leveling assisting section 22 and flows to the leveling adjusting section 31. Since the adjustment of the gap is 8 mm, the leveling adjustment unit 31 pushes away the elastic pavement material having a thickness of more than 8 mm, and the flow becomes F3 like the flow of the leveling assisting unit 22, and flows to S3.
[0061]
The elastic pavement material having a thickness of 8 mm or less passes through the lower end of the leveling adjustment unit 31 and flows to the finish adjustment unit 36. Since the adjustment of the gap is 4 mm, the finish adjusting section flushes out the excess elastic pavement material having a thickness of more than 4 mm, the flow becomes F4, flows to the area S4 where the elastic pavement material is not yet leveled, and the elasticity of 4 mm or less is obtained. The pavement material passes through the lower end of the finish adjusting unit 36 and forms a finished surface.
[0062]
When reaching the end of the pavement surface, the worker changes direction, contracts the hydraulic cylinder 46 of the towing frame 28, and tilts the left end of the rake body 23 backward and the right end forward with respect to the traveling direction. The leveling assist unit 22 is contracted with the hydraulic cylinder 33 contracted, and the left end is tilted forward and the right end is tilted backward with the rotation mechanism as the center.
[0063]
As described above, since the leveling assisting portion 22 performs leveling at the front of the leveling adjusting portion 31, the elastic pavement material is wider than the leveling portion 21 that leveles only on one side of the V-shaped slope. Can be averaged. Further, even if the angle of inclination of the rake body 23 changes, the leveling assisting part 22 can be rotated by expanding and contracting the hydraulic cylinder 46 to obtain an optimum angle.
[0064]
FIG. 6 is a diagram illustrating a construction method using the slide mechanism according to the second embodiment of the present invention.
An example in which the second layer is constructed from the left side of the pavement surface 52 will be described.
The operator tilts the left end of the rake body 23 forward and the right end backward with respect to the traveling direction, and moves the leveling assist unit 22 around the turning mechanism, the left end backward, and the right end forward. Incline.
Then, the finished surface is formed such that a boundary W, which is struck from the surface on which the finishing is not completed to the finished surface due to the difference in the thickness of the elastic pavement material, is located at the left end of the rake body 23 in the traveling direction.
The boundary W may be shifted to the left in the traveling direction from the width of the rake body 23 forming the finished surface depending on the location. In this case, the hydraulic cylinder 42 of the slide mechanism 26 is contracted while proceeding. The slide mechanism 26 is connected to the vehicle via the traction frame 28 and is fixed in the lateral direction. Therefore, when the hydraulic cylinder 42 is contracted, the slide portion 25 slides in the slide mechanism 26. Thus, the rake main body 23 slides to the left, and the leveling of the elastic pavement material can be performed without changing the inclination angle of the rake main body 23 with respect to the boundary W.
As a result, it is possible to minimize the overlapping of the finished surfaces formed by the rake main body and to perform an efficient operation. Also, since it is not necessary to change the angle of inclination of the rake body 23, it is not necessary to perform a meandering operation while turning the steering wheel to the left and right of the vehicle to be towed, so that stable work can be performed.
[0065]
FIG. 7 shows an example in which the rake according to the second embodiment of the present invention is towed by a vehicle 48.
FIG. 7 is an external perspective view of a rake towed by a vehicle.
[0066]
The operator gets on the vehicle 48 and connects the towing portion 43a of the frame portion 43 and the suspension 45 to the towing link or the like on the side of the vehicle 48 from the rake 20 to tow and level the work.
The hydraulic cylinders 33, 42, and 46 can be operated from the towing vehicle 48 to control the rotation of the leveling assist unit 22, the finish adjusting unit 36, and the slide of the slide mechanism 26. Spreading work becomes possible.
[0067]
The means for sliding or rotating the finishing part and the leveling assist part can be realized by a hydraulic cylinder or the like, so that a heavy object such as a rotary motor is not required, and the vehicle is used because the rake is pulled and leveled. Since a small one can be used and the total weight of the rake and the vehicle can be as light as 300 kg or less, not only the first layer but also the second layer can be performed.
[0068]
【Example】
(Example 1)
The exercise facility was constructed using the elastic pavement construction rake of the first embodiment.
The leveling part is 450mm, the finished part is 1000mm, the position of 100mm from each end of the finished part is bent at an angle of 145 °, and the joint angle between the leveled part and the finished part is 35 °, and a rake is manufactured. Use a mixture of main agent and curing agent at a ratio of 1: 1. 2 Of the second layer was performed.
The gap was adjusted to 8 mm in the leveling portion and 4 mm in the finished portion.
As a result, the leveling and finishing of the elastic pavement material can be performed by one operator in five hours, which has conventionally required two workers in five hours. Was also as good as 4.0 ± 0.2 mm.
[0069]
(Example 2)
The leveling part is 800 mm, the leveling auxiliary part is 1000 mm, the finished part is 2000 mm, and the position 200 mm from each end of the finished part is bent at an angle of 145 °, and the joint angle between the leveled part and the finished part is raked at 35 °. Manufactured and used as a resilient pavement material, a mixture of a main agent and a curing agent at a ratio of 1: 1. 2 Of the second layer was carried out by towing with a vehicle.
The gap was adjusted by adjusting the gap of the leveling assisting portion to 15 mm, the gap of the leveling portion to 8 mm, and the gap of the finished portion to 4 mm.
As a result, the leveling and finishing of the elastic pavement material could be performed by one worker in two hours, and the finishing of the surface of the second layer was as good as 4.0 ± 0.2 mm.
[0070]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained.
[0071]
(1) The leveling section having a different inclination angle with respect to the traveling direction from the finishing section pushes out the elastic pavement material before the finishing section to perform the finishing, thereby performing leveling. With this, the leveling section can push away excess elastic pavement material to form the finished surface, and can flow an appropriate amount of elastic pavement material to form the finished surface to the finishing section. The finishing unit performs finishing, which is the post-process of the second layer, while performing leveling, which is the pre-process of the two layers, so that one worker can perform the pre-process and post-process at the same time. Labor-saving work to spread paving materials can be achieved.
[0072]
(2) Since the rake main body is supported by the support portion, stable spreading work can be performed. In addition, the thickness from the imaginary plane connecting the lower ends of the support portions to the lower end of the finishing portion is the thickness when the elastic pavement material is laid, so that a highly accurate thickness can be formed.
[0073]
(3) Since the gap between the lower end of the leveling adjustment unit and the reference surface can be changed, the leveling adjustment unit applies an appropriate amount of elastic pavement material according to the thickness of the finished surface to the leveling adjustment unit. Since the excess elastic pavement material can be passed through the lower end and flown to the finishing portion, and the excess elastic pavement material can be washed away, the finished surface can be accurately formed.
[0074]
(4) The gap between the lower end of the finish fixing part and the reference surface can be changed, and the thickness of the elastic pavement material required for forming the finish surface can be made, so the thickness of the finish surface according to various exercise facilities Can be accurately formed.
[0075]
(5) The leveling section having a different inclination angle with respect to the traveling direction from the finishing section flushes the elastic pavement material before the finishing section to perform the finishing, thereby performing the leveling. Thereby, an excess amount of the elastic pavement material for forming the finished surface can be washed away, and an appropriate amount of the elastic pavement material for forming the finished surface can be flowed to the finishing portion. While the leveling of the elastic pavement material is performed, finishing, which is a post-process of the second layer, can be performed in the finishing portion, and the pre-process and the post-process can be performed simultaneously. Also, by connecting the tow frame to the vehicle and towing it, the construction period can be significantly reduced.
When the operator forms the finished surface, the finished surface of the finished part can be slid in the horizontal direction while maintaining the angle of inclination of the rake body with respect to the traveling direction, so the finished surface formed by the finished part Can be minimized, and efficient work can be performed.
In addition, since it is not necessary to change the inclination angle of the finishing part, it is not necessary to perform a meandering operation while turning the steering wheel to the left and right of the vehicle to be towed.
[0076]
(6) Since the leveling assisting part performs leveling at the tip of the leveling part, it can be leveled more widely than the leveling part that is leveled only on one side of the V-shaped inclined surface. In addition, by rotating the leveling assisting portion, even if the angle of inclination of the finishing portion with respect to the traveling direction changes, the angle can be set to an optimum angle, and more efficient leveling work can be performed.
[0077]
(7) Since the gap between the lower end of the leveling adjustment unit and the reference surface can be changed, the leveling adjustment unit applies an appropriate amount of elastic pavement material according to the thickness of the finished surface to the leveling adjustment unit. Since the excess elastic pavement material can be passed through the lower end and flown to the finishing portion, and the excess elastic pavement material can be washed away, the finished surface can be accurately formed.
[0078]
(8) The gap between the lower end of the finish fixing part and the reference surface can be changed, and the thickness of the elastic pavement material necessary for forming the finish surface can be made, so the thickness of the finish surface according to various exercise facilities Can be accurately formed.
