Description

【０００１】
【産業上の利用分野】
本発明は、例えば、立体駐車場等の建造物に付設される傾斜路構造に関する。
【０００２】
【従来の技術】
立体駐車場等の建造物に付設される傾斜路は、水平上面（車路面）を有する上層階、例えば２階と、ほぼ水平面からなる下層階、例えば地面との間に配置されている。この傾斜路は、２階の水平上面の側縁と地面との間を直線状に延在するよう配設されている（特許文献１参照）。傾斜路と２階の水平上面とが交わる部分は鈍角をなしている。したがって、特に車高の低い自動車が走行した場合には、腹やマフラをこするおそれがある。これを防ぐためには、傾斜路の長さを十分長くして上記角度を大きくすればよいが、設置スペースが過剰に広くなると共に、傾斜路が大型化するのでコストが大幅にアップすることになる。他方、設置スペースに厳しい制約のある場合には、傾斜路の長さが厳しく制約されるので、上記課題を解消できない場合が生ずる。

【課題を解決するための手段】
本発明によれば、実質的に水平な第１の面と、第１の面よりも高い位置にある、実質的に水平な第２の面とを接続する傾斜路構造において、
第１の面に戴置される支柱手段を含む支持枠手段と、支持枠手段の上面に離脱自在に取り付けられた複数の床部材とを備え、床部材の各々の上面により実質的に一定の幅で長手方向に延在するよう形成される路面は、第２の面の側縁に対し側外方に間隔をおいた位置であって、第２の面よりも低い位置から第１の面に向かって下方に傾斜する傾斜路面と、第２の面と傾斜路面とを実質的に連続させる円弧路面とを備え、

複数の横枠部材は、支柱対の各々を構成する支柱の上端部間、又は一部の支柱対を除く複数の支柱対の各々を構成する支柱の上端部間、及び側枠部材の各々間に離脱自在に連結される、
ことを特徴とする傾斜路構造、が提供される。
円弧路面の半径は、ほぼ８，１１０ｍｍに設定される、ことが好ましい。
複数の床部材は、該長手方向の一端部が支持枠手段の傾斜上面の下端部に離脱自在に取り付けられかつ長手方向の他端部が第１の面に戴置される１個の床部材を含む、ことが好ましい。
側枠部材の各々において、相互に該幅方向に対向する位置であって、側枠部材の各々の該長手方向に所定の間隔をおいた複数の位置には、それぞれ該幅方向外側に張り出す張出板が固定され、張出板の各々の上面は側枠部材の各々の上面と実質的に同一面上に位置付けられ、張出板の各々には、張出板の各々の上面から直角に上方に延び出して該幅方向に延在する直立板が固定され、相互に該幅方向に対向する張出板の各々に固定された直立板の各々は、直立板の各々の一側面同士が相互に側枠部材の各々の該長手方向に間隔をおいて対向するよう位置付けられ、床部材の各々は、各々の該幅方向の両側部における該長手方向の端面が相互に、対応する直立板を隙間をおいて挟んで対向するよう位置付けられると共に、各々の該幅方向の両側部において、相互に対向する端面近傍の下面が、対応する張出板の上面に戴置されてボルトにより離脱自在に締結される、ことが好ましい。
最も低い支柱対と、中間の高さを有する支柱対と、最も高い支柱対とは、それぞれ中空パイプ部材と、上端部が中空パイプ部材の下端部に離脱自在にねじ結合されかつ下端には第１の面に戴置される基板が装着されたジャッキ部材とを備えている、ことが好ましい。

【０００７】
【発明の実施の形態】
以下、本発明に従って構成された傾斜路構造の実施形態を、添付図面を参照して詳細に説明する。図１〜図３を参照して、本発明による傾斜路構造１００は、実質的に水平な第１の面、実施形態においては地面１と、地面１よりも高い位置にある、実質的に水平な第２の面、実施形態においては立体駐車場２００の上面である床面２０２とを、相互に実質的に連続するよう接続している。
【０００８】
傾斜路構造１００は、地面１に戴置される支柱手段（後述する）を含む支持枠手段２と、支持枠手段２の上面に離脱自在に取り付けられた複数の床部材、実施形態においては、１個の床部材４、実質的に同じ構成を有する４個の床部材６、及び１個の床部材８を備えている。後の説明から容易に理解されるように、床部材４〜８の各々により一定の幅で長手方向（図２において左右方向）に延在する傾斜路１０が形成される。支持枠手段２は、傾斜路１０の上記幅方向（図２において紙面の表裏方向）に間隔をおいて配置された支柱対であって、相互に高さが異なると共に高さの異なる順に長手方向に間隔をおいて配置された複数の支柱対、実施形態においては３個の（３対の）支柱対１２Ａ、１２Ｂ、１４Ａ、１４Ｂ及び１６Ａ、１６Ｂと、支柱対１２Ａ、１２Ｂを除く、支柱対１４Ａ、１４Ｂ及び１６Ａ、１６Ｂの各々の、上記幅方向の一方の上端部及び他方の上端部に離脱自在に連結されて相互に上記幅方向に間隔をおいて平行に上記長手方向に延在する側枠部材１８Ａ、１８Ｂ及び２０Ａ、２０Ｂと、複数の、実施形態において７個の横枠部材２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅ、２２Ｆ及び２２Ｇを含んでいる。後の説明から明らかなように、支柱対１２Ａ、１２Ｂの中空パイプ部材２４は、側枠部材１８Ａ、１８Ｂの長手方向端部に溶接により一体に連結されている。
【０００９】
支柱対１２Ａと１２Ｂ、支柱対１４Ａと１４Ｂ、及び支柱対１６Ａと１６Ｂは、それぞれ相互に共通部品から構成されている。また、側枠部材１８Ａと１８Ｂは共通部品であるＨ鋼から構成され、側枠部材２０Ａと２０Ｂは共通部品であるＨ鋼から構成されている。更にはまた、横枠部材２２Ａ〜２２Ｇの各々はＨ鋼から構成されている。横枠部材２２Ａ、２２Ｂ、２２Ｃ、２２Ｅ及び２２Ｆは、それぞれ相互に共通部品から構成されている。更にはまた、４個の床部材６の各々は、それぞれ共通部品から構成されている。このような多くの部品の共通化は、傾斜路構造１００の構成の簡略化、軽量化及びコストの大幅な低減を可能にする。
【００１０】
支柱手段を構成する３対の支柱対１２Ａ、１２Ｂ、１４Ａ、１４Ｂ及び１６Ａ、１６Ｂは、最も高さの低い（最も短い）支柱対１２Ａ、１２Ｂと、最も高さの高い（最も長い）支柱対１６Ａ、１６Ｂと、中間の高さを有する（中間の長さを有する）支柱対１４Ａ、１４Ｂとからなる。図４及び図５に示されているように、最も低い支柱対１２Ａ、１２Ｂの各々は、横断面がほぼ矩形状をなす中空パイプ部材２４と、ジャッキ部材２６とを備えている。中空パイプ部材２４内の下端部における中心部には、円筒状の雌ねじ部材２８が一体に固着されている。ジャッキ部材２６は、地面１に戴置される基板３０と、基板３０の中心部から直立する円筒状の雄ねじ部材３２とを備えている。基板３０は、大きな直径を有する大きな円板３０ａと、小さな直径を有する小さな円板３０ｂとからなり、小さな円板３０ｂは、大きな円板３０ａの上面に対し同心の位置に重合され、溶接により固定されている。ジャッキ部材２６は、雄ねじ部材３２の上端部が中空パイプ部材２４の雌ねじ部材２８に離脱自在にねじ結合されることにより、中空パイプ部材２４の下端部に回転自在に連結されている。最も低い支柱対１２Ａ、１２Ｂの各々は、ジャッキ部材２６を、中空パイプ部材２４に対して回転させることにより高さが調整される。
【００１１】
図２を参照して、最も高い支柱対１６Ａ、１６Ｂの各々は、横断面が円形状をなす中空パイプ部材３４と、ジャッキ部材３６とを備えている。また、中間の高さを有する支柱対１４Ａ、１４Ｂの各々は、横断面がほぼ矩形状をなす中空パイプ部材３７と、ジャッキ部材３８とを備えている。最も高い支柱対１６Ａ、１６Ｂの各々における中空パイプ部材３４及びジャッキ部材３６の構成、及び、中間の高さを有する支柱対１４Ａ、１４Ｂの各々における中空パイプ部材３７及びジャッキ部材３８の構成は、先に述べた、最も低い支柱対１２Ａ、１２Ｂの各々における中空パイプ部材２４及びジャッキ部材２６の構成と、基本的には同じであるので、説明は省略する。最も高い支柱対１６Ａ、１６Ｂの各々及び中間の高さを有する支柱対１４Ａ、１４Ｂの各々も、最も低い支柱対１２Ａ、１２Ｂの各々と同じように高さの調整が自在である。なお、支柱対１２Ａ、１２Ｂ、１４Ａ、１４Ｂ及び１６Ａ、１６Ｂと、支柱対１２Ａ、１２Ｂ、１４Ａ、１４Ｂ及び１６Ａ、１６Ｂにおける中空パイプ部材２４、３４及び３７の傾斜した上端は図示しない板部材からなるふたにより閉塞されている。
【００１２】
図２及び図３を参照して、直線状のＨ鋼から構成されている側枠部材１８Ａ、１８Ｂの各々の一端部（図２及び図３において右端部）は、中間の高さを有する支柱対１４Ａ、１４Ｂの各々における中空パイプ部材３７の上端部に離脱自在に連結されている。図１０に明示されているように、支柱対の一方１４Ａにおける中空パイプ部材３７の上端部の一側面であって、傾斜路１０の低い方向に面した一側面には、矩形状の連結板４０が該一側面から直角に延び出すよう溶接により固定されている。側枠部材の一方１８Ａの一端部と支柱対の一方１４Ａにおける中空パイプ部材３７の上端部との連結は、側枠部材の一方１８Ａの一端部におけるウェブ１８ａの片面が連結板４０の片面に重合され、図示しない複数のボルト＆ナットにより締結されることにより行われる。ボルト＆ナットにより相互に締結される、側枠部材の一方１８Ａの該一端部におけるウェブ１８ａ及び支柱対の一方１４Ａにおける中空パイプ部材３７の該上端部に固定された連結板４０には、図示しない複数の取付孔が形成されていることはいうまでもない。側枠部材の他方１８Ｂの一端部と支柱対の他方１４Ａにおける中空パイプ部材３７の上端部との連結も、図１０に示されている連結手段と実質的に同じ連結手段により離脱自在に連結されているので、説明は省略する。他方、側枠部材１８Ａ、１８Ｂの各々の他端部（図２及び図３において左端部）は、最も低い支柱対１２Ａ、１２Ｂにおける中空パイプ部材２４が、それぞれ溶接により一体に連結されている（図４及び図５参照）。側枠部材１８Ａ、１８Ｂと最も低い支柱対１２Ａ、１２Ｂにおける中空パイプ部材２４とのユニット化は、支持枠手段２の構成の簡略化、組立性の向上などに寄与する。
【００１３】
図２、図３と共に図９〜図１１を参照して、Ｈ鋼から構成されている側枠部材２０Ａ、２０Ｂの各々の一端部（図２、図３及び図１１において右端部）は円弧状に形成され、したがって、側枠部材２０Ａ、２０Ｂの各々の一端部の上面（Ｈ鋼の上側のフランジ２０ｂの上面）は、それぞれ円弧上面をなしている。側枠部材２０Ａ、２０Ｂの各々の一端部の上面と下面（Ｈ鋼の下側のフランジ２０ｃの下面）は共通の円弧中心を有している。側枠部材２０Ａ、２０Ｂの各々の他の領域は、下方に向かって直線状に延びている。このように形成された側枠部材２０Ａ、２０Ｂの各々の一端部（最端部）は、最も高い支柱対１６Ａ、１６Ｂの各々における中空パイプ部材３４の上端部に離脱自在に連結され、また各々の他端部（図２、図３及び図１１において左端部）は、中間の高さを有する支柱対１４Ａ、１４Ｂの各々における中空パイプ部材３７の上端部に離脱自在に連結されている。側枠部材２０Ａ、２０Ｂの各々の一端部（最端部）と、最も高い支柱対１６Ａ、１６Ｂの各々における中空パイプ部材３４の上端部との連結、及び、側枠部材２０Ａ、２０Ｂの各々の他端部と中間の高さを有する支柱対１４Ａ、１４Ｂの各々における中空パイプ部材３７の上端部との連結も、図１０に示されている連結手段と実質的に同じ連結手段により離脱自在に連結されているので、説明は省略する。なお、図９〜図１１において、該連結手段を構成する同一部分は同一符号で示されている。上記支持枠手段２の一部を構成する最も高い支柱対１６Ａ、１６Ｂの各々は、立体駐車場２００と共通の支柱対により構成されている。
【００１４】
図２、図３及び図１０を参照して、横枠部材２２Ｄの一端部（図３及び図１０において下端部）は、中間の高さを有する支柱対の一方１４Ａにおける中空パイプ部材３７の上端部に離脱自在に連結されている。図１０に明示されているように、支柱対の一方１４Ａにおける中空パイプ部材３７の上端部の一側面であって、支柱対の他方１４Ｂに対向する側（傾斜路１０の幅方向内側）の一側面には、矩形状の連結板４２が該一側面から直角に延び出すよう溶接により固定されている。横枠部材２２Ｄの一端部と、中間の高さを有する支柱対の一方１４Ａにおける中空パイプ部材３７の上端部との連結は、横枠部材２２Ｄの一端部におけるウェブ２２ａの片面が連結板４２の片面に重合され、図示しない複数のボルト＆ナットにより締結されることにより行われる。ボルト＆ナットにより相互に締結される、横枠部材２２Ｄの該一端部におけるウェブ２２ａ及び支柱対の一方１４Ａにおける中空パイプ部材３７の該上端部に固定された連結板４２には、図示しない複数の取付孔が形成されていることはいうまでもない。横枠部材２２Ｄの他端の一端部と支柱対の他方１４Ｂにおける中空パイプ部材３７の上端部との連結も、図１０に示されている連結手段と実質的に同じ連結手段により離脱自在に連結されているので、説明は省略する。支持枠手段２の組み立てにおいて、多くの箇所で使用されている上記連結手段（図１０に代表して示されている）は、構成が簡単で、容易かつ確実にしかも迅速な組立及び分解を可能にし、設置時間及び分解撤去時間の短縮、コストの低減に寄与する。
【００１５】
横枠部材２２Ａの両端部は、最も低い支柱対１２Ａ、１２Ｂ近傍の側枠部材１８Ａ、１８Ｂに離脱自在に連結されている。横枠部材２２Ｂ及び２２Ｃの両端部は、それぞれ、最も低い支柱対１２Ａ、１２Ｂと中間の高さを有する支柱対１２Ａ、１２Ｂとの間における側枠部材１８Ａ、１８Ｂに離脱自在に連結されている。横枠部材２２Ｅ及び２２Ｆの両端部は、それぞれ、中間の高さを有する支柱対１２Ａ、１２Ｂと最も高い支柱対１６Ａ、１６Ｂとの間における側枠部材２０Ａ、２０Ｂに離脱自在に連結されている。また、横枠部材２２Ｇの両端部は、それぞれ、最も高い支柱対１６Ａ、１６Ｂにおける中空パイプ部材３７の上端部に離脱自在に連結されている。これらの各連結は、相互に実質的に同じ連結手段により離脱自在に連結されているので、それらを代表して、横枠部材２２Ｂの一端部と、側枠部材の一方１８Ａとの連結手段について説明する。図６〜図８を参照して、側枠部材の一方１８Ａの内側面（傾斜路１０の幅方向内側面）には、連結板４４が該内側面から直角に延び出すよう溶接により固定されている。横枠部材２２Ｂの一端部と側枠部材の一方１８Ａとの連結は、横枠部材２２Ｂの一端部におけるウェブ２２ａの片面が連結板４４の片面に重合され、図示しない複数のボルト＆ナットにより締結されることにより行われる。ボルト＆ナットにより相互に締結される、横枠部材２２Ｂの該一端部におけるウェブ２２ａ及び側枠部材の一方１８Ａに固定された連結板４４には、それぞれ、複数の取付孔２３及び４５が形成されていることはいうまでもない。
【００１６】
図２及び図９を参照して、中間の高さを有する支柱対１４Ａ、１４Ｂにおける中空パイプ部材３７と側枠部材１８Ａ、１８Ｂ及び側枠部材２０Ａ、２０Ｂとの間には、それぞれ、ブレース部材４６及び４７が離脱自在に装着されている。また、支柱対１４Ａ、１４Ｂにおける中空パイプ部材３７と横枠部材２２Ｄとの間にも、それぞれ、図示しないブレース部材が離脱自在に装着されている。同様に、最も高い支柱対１６Ａ、１６Ｂにおける中空パイプ部材３４と側枠部材１８Ａ、１８Ｂ及び立体駐車場２００の側枠部材２０４との間には、それぞれ、ブレース部材４８及び４９が離脱自在に装着されている。また、支柱対１６Ａ、１６Ｂにおける中空パイプ部材３４と横枠部材２２Ｇとの間にも、それぞれ、図示しないブレース部材が離脱自在に装着されている。
【００１７】
図３を参照して、側枠部材１８Ａ、１８Ｂ及び側枠部材２０Ａ、２０Ｂの各々において、相互に上記幅方向に対向する位置であって、側枠部材１８Ａ、１８Ｂ及び側枠部材２０Ａ、２０Ｂの各々の上記長手方向に所定の間隔をおいた複数の位置、実施形態においては片側５箇所、両側で１０箇所の位置には、それぞれ上記幅方向外側に張り出す張出板５０が溶接により固定されている。張出板５０の各々は、側枠部材１８Ａ、１８Ｂ及び側枠部材２０Ａ、２０Ｂの各々において、それぞれ、横枠部材２２Ａ〜２２Ｃ、２２Ｅ及び２２Ｆが連結されている部分の、上記幅方向外側にそれぞれ配設されている。張出板５０の各々は相互に共通の部品からなり、また張出板５０の各々の、対応する側枠部材１８Ａ、１８Ｂ及び側枠部材２０Ａ、２０Ｂに対する装着形態及び関連構成も実質的に同じであるので、以下、それらを代表して、側枠部材１８Ａにおいて、横枠部材２２Ｂが連結されている部分の、上記幅方向外側に配設されている張出板５０、張出板５０の装着形態及び関連構成について説明する。
【００１８】
図６〜図８を参照して、上記長手方向に縦長の矩形状をなす張出板５０は、側枠部材１８Ａにおける上側のフランジ１８ｂの、上記幅方向外側の側面から側外方に延び出している。張出板５０の基端は、側枠部材１８Ａの上側のフランジ１８ｂの、上記幅方向外側の側面に溶接により固定されている。張出板５０の長手方向両端部には、取付孔５１が形成されている。張出板５０の上面は、側枠部材１８Ａの上面、すなわち、側枠部材１８Ａの上側のフランジ１８ｂの上面と実質的に共通の平面上に位置付けられている。張出板５０の下方には、補強板５２が配設されている。矩形状をなす補強板５２は、側枠部材１８Ａのウェブ１８ａの、上記幅方向外側の側面から側外方に延び出すよう、側枠部材１８Ａに溶接により固定されている。補強板５２の上端面は、張出板５０の長手方向の中央下面に溶接により固定されている。張出板５０の長手方向の中央には、張出板５０の上面から直角に上方に延び出して上記幅方向に延在する、矩形状の直立板５４が溶接により固定されている。直立板５４の、該幅方向の長さは張出板５０の幅と同じである。図３から容易に理解されるように、相互に該幅方向に対向する張出板５０の各々に固定された直立板５４の各々は、直立板５４の各々の一側面同士が相互に対向するよう位置付けられる。
【００１９】
図１、図２及び図１１を参照して、床部材４、６及び８の各々は、それぞれ、鉄筋が内蔵されたコンクリートから一体に形成されている。相互に共通の部品からなる床部材６の各々は、矩形の平面形状をなす本体部６２と、本体部６２の、上記幅方向両側縁部からそれぞれ上方に延び出すフェンス部６４とを備えている。本体部６２とフェンス部６４とは一体に形成されている。本体部６２は、ほぼ一定の厚さを有すると共に、その上面及び下面は相互に平行な平坦面をなしている。フェンス部６４は、本体部６２の、上記幅方向両側縁部の全域にわたって形成され、上記幅方向に見て、矩形状をなしている。床部材４は、矩形の平面形状をなす本体部４２と、本体部４２の、上記幅方向両側縁部からそれぞれ上方に延び出すフェンス部４４とを備えている。本体部４２とフェンス部４４とは一体に形成されている。本体部４２は、ほぼ一定の厚さを有すると共に、その上面及び下面は相互に平行な平坦面をなしている。フェンス部４４は、本体部６２の、上記幅方向両側縁部の一端部（図２において左端部）を除く全域にわたって形成され、上記幅方向に見て、矩形状をなしている。
【００２０】
床部材８は、矩形の平面形状をなす本体部８２と、本体部８２の、上記幅方向両側縁部からそれぞれ上方に延び出すフェンス部８４とを備えている。本体部８２とフェンス部８４とは一体に形成されている。本体部８２は、ほぼ一定の厚さを有すると共に、その上面及び下面は共通の円弧中心を有する円弧面をなしている。この円弧中心は、側枠部材２０Ｂの上記円弧中心と共通の円弧中心である。本体部８２の下面の円弧の半径は、側枠部材２０Ｂの上面の円弧の半径とほぼ同じである。本体部８２の上面を形成する円弧面の半径は、ほぼ８，１１０ｍｍに設定されることが重要である。フェンス部８４は、本体部８２の、上記幅方向両側縁部の全域にわたって形成され、その上端は、本体部８２の上面及び下面と共通の円弧中心を有する円弧面をなしている。床部材４、６及び８の本体部４２、６２及び８２の厚さは相互に実質的に同じであり、また、フェンス部４４、６４及び８４の高さも相互に実質的に同じである。

[Industrial application fields]
The present invention relates to a ramp structure attached to a building such as a multilevel parking lot, for example.
[0002]
[Prior art]
A ramp attached to a building such as a multi-story parking lot is arranged between an upper floor having a horizontal upper surface (vehicle road surface), for example, the second floor, and a lower floor having a substantially horizontal plane, for example, the ground. This ramp is arranged so as to extend linearly between the side edge of the horizontal upper surface of the second floor and the ground (see Patent Document 1). The part where the ramp and the horizontal upper surface of the second floor intersect forms an obtuse angle. Therefore, there is a risk of rubbing the stomach and the muffler especially when an automobile with a low vehicle height travels. In order to prevent this, the length of the ramp should be made sufficiently long to increase the angle. However, the installation space becomes excessively wide, and the ramp increases in size, which greatly increases the cost. . On the other hand, when the installation space is severely restricted, the length of the ramp is severely restricted, and thus the above problem cannot be solved.
