Description

【０００１】
【発明の属する技術分野】
本発明は階段をリフォームするための施工性に優れた蹴込板部材と、この蹴込板部材を用いて体裁よくリフォームすることができる階段の構造に関するものである。
【０００２】
【従来の技術】
従来から、既存の階段を解体することなくそのまま使用して新規な階段にリフォーム（改築）するには、例えば、特開２００１−３５３５に記載されているように、既存の蹴込板の下端部を固定させている下側の既存踏板における後端部上面に、上記既存蹴込板の上端部から前方に突出している上側の既存踏板の突出長さに等しい幅を有する角棒形状の当て木を配設して該当て木の後面を既存の蹴込板の下端部前面に当接させた状態で既存の踏板に釘着し、しかるのち、この当て木の前面に新設蹴込板の下端部後面を密接させると共に上側の既存踏板の前端面に該新設蹴込板の上端部後面を密接させて釘着することにより新設蹴込板を施工し、次いで、既存の踏板の上面に新設踏板を接着剤によって固定し、この新設踏板の前端部に下方に向かって突設している幕板部により上記新設蹴込板の上端部を被覆したリフォーム構造としている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記のようなリフォーム階段の構造では、新設蹴込板を既存の蹴込板の前方側に正確に張設、固定するには、当て木の前後方向の幅を現場において既存の蹴込板の上端部から前方に突出している上側の既存踏板の突出長さに等しい幅となるように切削加工をしなければならず、その加工に熟練と著しい手間を要し、リフォームが完了するまでの期間が長くなるという問題点があった。
【０００４】
また、新設蹴込板の上端部を既設の踏板の前端面に当接させた状態で釘着した場合、該新設蹴込板とその後方の既存蹴込板との間の空間部が密閉された状態となってその空間部を利用して新設蹴込板を外部から既存の踏板の後端部上面に固着させることができないために、上記のように先に、既存の踏板の後端部上面に所定幅に形成された当て木を配設してその後面を既存の蹴込板の下端部前面に当接させることにより所定の位置に釘着し、しかるのち、この当て木の前面に新設蹴込板の下端部後面を密接させて釘着しているために、当て木の加工精度が悪いと新設の蹴込板が垂直状態に張設することができない事態が発生し、外観を損することになる等の問題点があった。
【０００５】
本発明の上記のような問題点に鑑みてなされたもので、その目的とするところは、既存の階段をリフォームする際に、該階段の蹴込板の前面側に容易に且つ精度よく施工し得る新設蹴込板部材と、この新設蹴込板部材や新設踏板によって体裁よくリフォームされた階段の構造を提供するにある。
【０００６】
【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の請求項１に記載のリフォーム階段用蹴込板部材は、既存の階段における蹴込板の前面側に配してこの既存蹴込板を覆い隠す新設蹴込板部材であって、既存の階段の踏板における前端面に上端部後面を当接、固着させる新設蹴込板と、既存の階段の踏板における後端部上に固定させる固定部材とからなり、この固定部材は、上記踏板の長辺方向に長い細幅基板部に上方に向かって所定高さの前側壁板部とこの前側壁板部から後方に小間隔を存して該前側壁板部よりも高さの高い後側壁板部とを突設してこれらの前後壁板部間に上記新設蹴込板の下端部を挿入させて支持する上向き開口の溝を形成していることを特徴とする。
【０００７】
また、請求項２に係る発明は、上記請求項１に記載の蹴込板部材において、固定部材は、踏板の長辺方向に長い細幅基板部の一方の長辺縁を前端縁としてこの前端縁から上方に向かって所定高さの前側壁板部を突設していると共に基板部の該前端縁から後方に小間隔を存した上面にこの前側壁板部と平行して後側壁板部を突設してなり、さらに、後側壁板部の前面に新設蹴込板の下端部後面を弾力的に押圧する軟質片を一体に設けていると共に前側壁板部の上端に新設踏板の後端部上面を被覆する被覆片を前方に向かって突設していることを特徴とする
【０００８】
請求項３に係る発明は、請求項１に記載の新設蹴込板部材を使用したリフォームされた階段の構造であって、既存の階段の踏板の長辺方向に長い細幅基板部に上方に向かって所定高さの前側壁板部とこの前側壁板部から後方に小間隔を存して該前側壁板部よりも高さの高い後側壁板部とを突設してこれらの前後壁板部間に上向きに開口した溝を設けている固定部材を既存の階段における下側の踏板の後端部上面に固定すると共にこの固定部材の上記溝に新設蹴込板の下端部を挿入、支持させてこの新設蹴込板の上端部を上記既存の踏板の上方に配設している上側既存踏板の前端面に固定してあり、さらに、既存の踏板の上面に新設の踏板を固定してこの新設踏板の前端部で新設蹴込板の上端部を被覆してなる構造を有している。
【０００９】
【作用】
請求項１に記載の新設蹴込板部材は、蹴込板と固定部材とが別体に形成されており、施工に際しては固定部材に設けている溝内に蹴込板の下端部を挿入、支持させて該蹴込板を固定部材から垂直に立設させる。この状態にして固定部材を既存の踏板上で前後方向に移動調整することにより、蹴込板の上端部を上方側の既存踏板の前端面に当接させ、固定部材を接着剤等によって固定すると共に蹴込板の上端部を上記上方側の踏板の前端面に釘打ち等によって固定する。
【００１０】
この場合、蹴込板の張設、固定を一層強固に行うためには、上記のように蹴込板の上端部が上方側の既存踏板の前端面に当接した状態となる位置に固定部材を下側の既存踏板上に位置決めしたのち、一旦、この固定部材を接着剤や両面テープで仮固定し、その溝から蹴込板を抜き取って固定部材の後部を踏板に釘着し、しかるのち、再び、この固定部材の溝に蹴込板の下端部を挿入、支持させ、該蹴込板の上端部を上方側の踏板の前端面に釘着すればよい。
【００１１】
上記いずれの新設蹴込板部材においても、階段をリフォームする際には既存の踏板上に配設する新設踏板の施工に先行して行われ、新設踏板は、その後端面を既に施工した新設蹴込板部材の下端部前面に当接させ且つ下方に屈曲形成してなる前端幕板部で下側の新設蹴込板部材の上端部を覆い隠した状態となるように固定され、請求項３に記載したリフォームされた階段の構造とする。この際、新設踏板はその後端面が新設蹴込板部材の下端部前面に当接し且つ下方に向かって直角に屈曲している前端幕板部によって下側の新設蹴込板部材の上端部を覆うことができるように、その前後幅の寸法を切断によって調整する。
【００１２】
【発明の実施の形態】
次に、本発明の具体的な実施の形態を図面について説明すると、図１（イ）〜（ニ）は、正面横長長方形状に形成された一定厚みを有する蹴込板部１の下端に後方に向かって固定部２を突設してなる断面Ｌ字形状の蹴込板部材Ａを示すもので、図２に示すように、階段をリフォームする際に、既存の蹴込板11の前方近傍部に施工されて該既存の蹴込板11を覆い隠すものであり、図１（イ）に示した新設蹴込板部材Ａにおいては、蹴込板部１の下端部を後方に向かって直角に屈折して蹴込板部１と同じ厚みを有する一定幅の固定部２を形成してなるものである。なお、この新設蹴込板部材Ａは、蹴込板部１の高さと固定部２の突出幅との和に等しい縦幅を有する板材の下端から固定部２の突出幅に相当する高さ部分の後面側にＶ字状の切込溝を全長に亘って設け、この切込み部を介して下端部を後方に直角に折り曲げて接着剤により固定することにより製造することができる。
【００１３】
図１（ロ）に示した新設蹴込板部材Ａにおいては、蹴込板部１の下端部後面に一定幅を有する角棒形状の固定部２を接着剤によって一体に固着してなるもので、固定部２の下面と蹴込板部１の下端面とは面一となるように固定部２の前面を蹴込板部１の下端部後面に固着している。また、図１（ハ）に示す新設蹴込板部材Ａは、上記図１（イ）で示した新設蹴込板部材Ａにおける細幅板状の固定部２の上面に角棒部材2aを配設して、この角棒部材2aにおける互いに直角な前面と下面とを蹴込板部１の下端部後面と細幅板状の固定部２上とに接着剤によって固着することで、蹴込板部１と固定部２とを互いに直角にして固着している。
【００１４】
上記図１（イ）〜（ハ）に示した新設蹴込板部材Ａは、合板や中比重木質繊維板（ＭＤＦ）からなり、施工した際に外部に露出する蹴込板部１の前面を化粧シート張り、突板張り、塗装等によって表面化粧処理されているものであるが、図１（ニ）に示した新設蹴込板部材Ａは、蹴込板部１とこの蹴込板部１の下端から後方に向かって直角に突設している細幅板状の固定部２とは樹脂成形によって一体に形成してなるものである。なお、いずれの新設蹴込板部材Ａにおいても、蹴込板部１の上端部や固定部２の後端部を切断可能にして高さ寸法や幅寸法の調整が可能となるように形成している。また、これらの新設蹴込板部材Ａの横幅（長さ）は、その両側端面が階段の側桁12、12の対向面に接合して既存の蹴込板11を全面的に被覆するように形成されている。
【００１５】
一方、上記階段における既存の踏板13を被覆する新設の踏板Ｂは、図２〜図４に示すように、一定厚みを有する平面横長長方形状の踏板部３の前端部に、該踏板３に対して下方に向かって直角に屈曲した幕板部４を一体に形成してなる構造を有している。なお、この踏板Ｂは木質材から形成されてあり、表面には上記新設蹴込板部材Ａと同様に化粧シートや化粧板の貼着等によって化粧を施されている。なお、この新設踏板Ｂの長さも上記新設蹴込板部材Ａと同様に、その両側端面が階段の側桁12、12の対向面に接合する長さ寸法に形成されている。
【００１６】
上記のように構成した新設蹴込板部材Ａと新設踏板Ｂとを用いて階段をリフォームするには、上下に隣接する既存の踏板13、13に新設蹴込板部材Ａ、Ａの施工を行ったのち、新設踏板Ｂの施工を順次行うものである。なお、新設蹴込板部材Ａは上記図１（イ）〜（ニ）に示したいずれの蹴込板部材であってもその施工方法は同じであるので、図１（イ）に示した新設蹴込板部材Ａについて説明する。まず、この新設蹴込板部材Ａを図３、図４において点線で示すように、その固定部２を下側の既存踏板13上に載置し、この固定部２に対して直角に形成している蹴込板部１を固定部２の前端から垂直上方に立設した状態にする。
【００１７】
この状態で固定部２を下側の既存踏板13上でその位置を前後方向に移動調整することにより、蹴込板部１の上端部後面を上側の既存踏板13の前端面に全長に亘って当接させ、蹴込板部１の上端部をその前面側から上側既存踏板13の前端面に向かって釘５を打ち込むことにより固着する。なお、固定部２の下面は両面テープ又は接着剤によって下側の既存踏板13の後端部上面に固着される。
【００１８】
この両面テープや接着剤は、新設蹴込板部材Ａの施工時に固定部２の下面に貼着又は塗布されるものであり、従って、固定部２を既存踏板13上に固定する際に、目安によって正確な位置を定めておいて位置調整を僅かで済むようにするか、或いは、この新設蹴込板部材Ａを浮かせた状態でその蹴込板部１の上端部後面を上側の既存踏板13の前端面に当接させ、この状態から該既存踏板13の前端面に摺接させながら新設蹴込板部材Ａを降下させ、固定部２の下面を下側の既存踏板13上に接着させれば正確に施工し得る。
【００１９】
このように新設蹴込板部材Ａを施工すると、この新設蹴込板部材Ａは、既存の蹴込板11の前面に対して、該既存の蹴込板11の上端から前方に突出している上側踏板13の前端部の突出幅に相当する間隔を存した位置に張設、固定された状態となり、この新設蹴込板部材Ａによって後方側に配されている上記既存の蹴込板11は全面的に覆い隠された状態となる。
【００２０】
この際、既存の蹴込板11から前方に突出する上側踏板13の突出幅が狭くて、施工すべき新設蹴込板部材Ａにおける固定部２の蹴込板部１からの突出幅が上記踏板13の突出幅よりも大きい場合には、固定部２の後部を適宜幅、切除することによりその突出幅の寸法を踏板13の突出幅よりも小幅にするものであり、同様に、蹴込板部１の高さ（縦幅）が上下踏板13、13の上面間の縦幅寸法よりも大きい場合には、該蹴込板部１の上端部を所望寸法だけ切断して上下踏板13、13の上面間の縦幅寸法よりも低くなるようにすればよい。
【００２１】
こうして既存の踏板13の後端部上に新設蹴込板部材Ａを順次、施工する一方、既に新設蹴込板部材Ａを施工している既存の踏板13上に新設踏板Ｂを施工する。この新設踏板Ｂは、その踏板部３を既存の踏板13上に重ね合わせて後端面をこの踏板13の後端部上に固定している新設蹴込板部材Ａの蹴込板部１の下端部前面に当接させると共に、踏板部３の前端から下方に直角に屈曲している前端幕板部４を既存の上記踏板13の前端面に釘着している下側の新設蹴込板部材Ａの蹴込板部１の上端部前面に当接させてこの蹴込板部１の上端部を覆い隠した状態とし、この状態にして既存の踏板13の上面にその下面を接着剤によって固着するか、或いは釘打ちすることにより固着する。
【００２２】
なお、この新設踏板Ｂを施工するに際して、その踏板部３の後端部を必要に応じて所定幅、切除することで、前端幕板部４により、既存の踏板13の前端面に釘着している上記下側の新設蹴込板部材Ａの蹴込板部１の上端部を覆い隠した時に踏板部３の後端面が上側の新設蹴込板部材Ａの蹴込板部１の下端部前面に当接するように幅調整を行う。こうして、既存の階段における全ての蹴込板11と踏板13とを図２に示すように、新設蹴込板部材Ａと新設踏板Ｂとによって被覆することにより階段をリフォームするものである。
【００２３】
次に、以上の実施の形態においては、新設蹴込板部材Ａとして、蹴込板部１の下端に後方に向かって直角に屈曲させた固定部２を一体に設けた構造を例示したが、蹴込板部と固定部とを別体に形成しておき、施工に際して組み合わせるように構成しておいてもよい。
【００２４】
図５は、その新設蹴込板部材A'の一例を示すもので、正面横長長方形状の蹴込板1'と、前端部上面にこの蹴込板1'の下端部を挿入させて支持する上向きに開口した溝24を形成している固定部材2'とから構成している。なお、これらの蹴込板1'と固定部材2'は、先に説明した実施の形態における新設蹴込板部材Ａと同様に、その長さ方向の両側端面が階段の側桁12、12の対向面に接合する長さ寸法に形成されている。
【００２５】
上記固定部材2'は、長さ方向に既存の踏板11の長さ方向に向けて配設する一定厚みを有する細幅の基板部21を有していると共にこの基板部21の前端側の長辺縁から上方に向かって前側壁板部22を突設してあり、さらに、この前側壁板部22から後方に蹴込板1'の厚みに略相当する間隔を存した基板部21の前部上面に、該前側壁板部22よりも高い高さの後側壁板部23を上方に向かって突設してあり、これらの前後壁板部22、23間に上記蹴込板1'の下端部が挿嵌可能な上向きに開口した溝24を形成している。そして、後側壁板部23から後方に突設している基板部21の後半部を固定用帯板部21' としている。なお、上記固定部材2'における前側壁板部22の高さは、既設の踏板11上に施工される新設踏板Ｂの厚みに等しい高さに形成している。
【００２６】
このように構成した固定部材2'を用いて既存の蹴込板11を覆い隠すように新設の蹴込板1'を張設するには、まず、固定部材2'の溝24内に蹴込板1'の下端部を挿嵌させて蹴込板1'を垂直に立設した状態に支持させ、この状態にして固定部材2'を既存の踏板13上で前後方向に移動調整することによって、蹴込板1'の上端部後面を上側の既存踏板13の前端面に当接させた状態にする。なお、固定部材2'の基板部21の下面には両面テープを貼着、又は接着剤を塗布してあり、蹴込板1'の上端部後面が上側の既存踏板13の前端面に当接するように固定部材2'を位置決めして、これらの両面テープ又は接着剤によって該固定部材2'を既存踏板13の後端部上に仮固定する。
【００２７】
ついで、固定部材2'の溝24から蹴込板1'の下端部を一旦、引き抜いて既存の蹴込板11の前端から前方に突出している上側の既存踏板13の下方空間部を外部に連通させた状態とし、固定部材2'の上方空間部を通じて、該下方空間部において既存の蹴込板1'の下端部前面に向かって突設している固定部材2'の後半部の固定用帯板部21' を釘５の打ち込みにより既存の踏板13に固着する。しかるのち、蹴込板1'を上側の既存の踏板13の前端面に沿って下ろすことによりその下端部を再び固定部材2'の溝24内に挿嵌、支持させると共に上側の既存踏板13の前端面に当接している該蹴込板1'の上端部を釘５の打ち込みによって既存踏板13に固着する。
【００２８】
なお、固定部材2'における溝24の後側壁板部23を前側壁板部22よりもその高さを高くしているので、新設蹴込板部材A'を施工する際に、この新設蹴込板部材A'の上下端部の後面を既存の踏板13の前端面と前側壁板部22から突出している後側壁板部23の前端面とに当接させた状態にしたのち、該新設蹴込板部材A'を下方に下ろして溝24内にその下端部を挿入させることにより施工が容易に行うことができるものである。
【００２９】
このようにして新設蹴込板部材A'を全ての既存踏板13上に既存の蹴込板11の前面を全面的に覆い隠すように施工する一方、既に新設蹴込板部材A'を施工している既設の踏板13上に上記実施の形態で示した新設踏板Ｂと同一形状、同一構造の新設踏板Ｂを同様な方法で施工する。
【００３０】
即ち、図６に示すように、この新設踏板Ｂを既存の踏板13上に重ね合わせてその後端面を新設蹴込板部材A'の固定部材2'における溝24の前側壁板部22の前面に当接させることにより該新設蹴込板部材A'の上面と前側壁板部22の上端面とを面一状に連続させた状態にすると共に、この新設蹴込板部材A'の踏板部３の前端から下方に直角に屈曲している前端幕板部４を既存の上記踏板13の前端面に釘着している下側の新設蹴込板部材A'の蹴込板1'の上端部前面に当接させてこの蹴込板1'の上端部を覆い隠した状態とし、この状態にして既存の踏板13の上面にその下面を接着剤によって固着するか、或いは釘打ちすることにより固着するものである。なお、新設踏板Ｂの前後端面間の幅寸法は上記実施の形態と同様に、必要に応じて所定幅、切除することで、前端幕板部４により下側の新設蹴込板部材A'の蹴込板1'の上端部を覆い隠した時に踏板部３の後端面が溝24の前側壁板部22の前面に当接するように幅調整を行っておくものである。
【００３１】
図７は、上記新設蹴込板部材A'における固定部材2'の変形例を示すもので、溝24の前側壁板部23の上端に新設踏板Ｂの踏板部３の後端部上面を被覆する弾性被覆片25を前方に向かって突設してなるものであり、弾性被覆片25によって溝24の前側壁板部22と新設踏板Ｂの後端面との接合部を被覆して若干の切断誤差がより該接合部に隙間が生じていてもそれを覆い隠して体裁のよいリフォーム階段を構成しているものである。この場合、固定部材2'の基板部21の前端を前側壁板部22の下端部から前方に向かって突出させた突出部21''を形成しておく一方、新設踏板Ｂの踏板部３の後端下半部を断面逆Ｌ字状に切り欠いてその切欠段部3aを上記固定部材2'の突出部21''に接合させると共に弾性被覆片25によって新設踏板Ｂの踏板部３の後端部上面を被覆させた構造としておいてもよい。
【００３２】
図８は新設蹴込板部材A'における固定部材2'の更に別な変形例を示すもので、固定部材2'における溝24を形成している前後板壁部22、23間の溝幅を、蹴込板1'の厚みよりも僅かに広く形成していると共に溝24の後側板壁部23の上端部前面に弾性軟質片26を一体に設けてあり、さらに、前側板壁部22の上端には上記実施の形態と同様に弾性被覆片25を設けている。そして、溝24の底面から釘５を既存の踏板13に打ち込むか、或いは、固定部材2'の基板部21の下面を既存の踏板13に両面テープや接着剤によって固定するようにしてあり、従って、固定部材2'の基板部21の後部には上述したような固定用帯板部21' を必ずしも設けておく必要はない。
【００３３】
また、この新設蹴込板部材A'における蹴込板1'の下端面にはクッション材27を貼着している。従って、既存の踏板13の後端部上の所定位置に固定部材2'を固定したのち、上記同様の施工方法により蹴込板1'の下端部を固定部材2'の溝24内に挿入してその下端クッション材27を溝底面に受止させた状態にすると共に蹴込板1'の上端部を上側の既存の踏板13の前端面に釘着して施工すると、弾性軟質片26によって蹴込板1'の下端部を溝24の前側壁板部22に積極的に押し付けて蹴込板1'がガタツクの防止することができると共に、新設踏板Ｂを踏みしめた時に、クッション材27によって音鳴りするのを防止することができる。
【００３４】
図９は、新設蹴込板部材A'における固定部材2'の別な形状を示すもので、基板部21を角棒形状に形成すると共にこの基板部21の上端面前後縁部から上方に向かって前側壁板部22と該前側壁板部22よりも突出高さが高い後側壁板部23とを突設してこれらの前後壁板部22、23間に蹴込板1'の厚みよりも僅かに幅広い溝24を形成してあり、さらに、前側壁板部22の上端から前方に向かって突設している被覆片25' を弾性片とすることなく硬質被覆片に形成している一方、後側壁板部23の上部前面には上記図８で示した固定部材2'と同様に弾性軟質片26を設けている。
【００３５】
さらに、固定部材2'の前面下部における下端面から小間隔を存した部分に前方に向かって支持突片28を突設してこの支持突片28と上記被覆片25' との間に新設踏板Ｂの踏板部３の後端部3aを挿入、支持させる前方に向けた開口した横溝29を形成している。なお、この横溝29に挿入する新設踏板Ｂの踏板部３の後端部3aはその下部を断面Ｌ字状に切欠かれている。
【００３６】
この固定部材2'を上記実施の形態と同様にして既存の踏板13の後端部上の所定位置に固定したのち、蹴込板1'の下端部を固定部材2'の溝24内に挿入、受止させると共に上端部を上側の既存の踏板13の前端面に釘着して施工し、しかるのち、この固定部材2'の上記横溝29内に新設踏板Ｂの踏板部３の後端部3aを挿入し、接着剤によって固定するか、又は、予め新設踏板Ｂと固定部材2'を釘着することによって固定するものである。
【００３７】
なお、上記固定部材2'はＡＢＳ等の樹脂成形品であって、基板部21及び前後壁板部22、24は硬質樹脂からなり、弾性被覆片25、25' や弾性軟質片26は軟質樹脂から形成されている。
【００３８】
次に、以上のいずれの実施の形態においても、新設蹴込板部材Ａ、A'の蹴込板部１や蹴込板1'は上端から下端に亘って面一の垂直な板部に形成しているが、図10に示すように、蹴込板1'' の上端部を前方に向かってＬ字状に屈曲させて既存の踏板13の前端面に当接させる垂直な板部1aとこの板部1aの下端から上記踏板13の前端部下面に沿って既存の蹴込板11の上端近傍部に達する水平板部1bとに形成しておいてもよい。
【００３９】
このように形成した蹴込板1'' を施工すると、該蹴込板1'' は既存の蹴込板11の前面に極めて接近した位置に配設されることになり、従って、既存の踏板13の上面に施工する新設踏板Ｂの前後幅間、即ち、踏み面が幅広くなって安定した姿勢でもって階段を安全に昇降することができる。なお、下端に固定部２を一体に設けている上記新設蹴込板部材Ａの踏板板部１においてもその上端部を上記のようにＬ字状に形成しておいてもよい。また、固定部２や固定部材2'を設けることなく上端部を上記のようにＬ字状に形成した蹴込板を、既存の蹴込板11の前面に重ね合わせて接着剤等により一体に固着した構造とすることもできる。
【００４０】
【発明の効果】
以上のように請求項１に係る発明によれば、既存の階段における蹴込板の前面側に配してこの既存蹴込板を覆い隠す新設蹴込板部材であって、既存の階段の踏板における前端面に上端部後面を当接、固着させる新設蹴込板と、既存の階段の踏板における後端部上に固定させる固定部材とから構成しているので、この固定部材を既存の踏板上に載置することによって新設蹴込板を踏板から簡単且つ正確に垂直に立設させることができ、この状態にして蹴込板の上端部を上記踏板に対して上方側の既存踏板の前端面に当接させてこの既存踏板に釘打ち等によって固定すると共に固定部材の下面を接着剤や両面テープ等で下側の既存踏板に固定することにより、新設蹴込板部材を容易に且つ精度よく施工することができる。
【００４１】
さらに、固定部材に上記新設蹴込板の下端部を挿入させて支持する上向き開口の溝を形成しているので、予め、固定部材を既存の踏板の上面における新設蹴込板取付位置に固定したのち、この固定部材の溝に新設蹴込板の下端部を挿入、支持させることにより、該新設蹴込板を所定位置に簡単且つ正確に張設、施工することができる。その際、新設蹴込板を固定部材上に配設する前には、この新設蹴込板により覆い隠される上下踏板間の空間部が外部に連通した状態であるから、固定部材の後部を既存の踏板の後端部上に釘着することによって強固に固着することができ、しかるのち、新設蹴込板を立設することによってその釘着部を外部から隠蔽し得るので、体裁のよい且つ強固な新設蹴込板取付構造とすることができる。その上、固定部材と蹴込板とは別体に形成しているから、蹴込板を自由に選択することができ、従って、品揃えも少なくてすみ、現場調達品等も自由に使用することができる。
【００４２】

[0015]
  On the other hand, as shown in FIG. 2 to FIG. 4, a newly installed tread B that covers the existing tread 13 in the above staircase is formed on the front end of the flat horizontally long rectangular tread 3 having a certain thickness with respect to the tread 3. Thus, the curtain plate portion 4 bent at a right angle downward is integrally formed. The tread board B is made of a wood material, and the surface is decorated by applying a decorative sheet or a decorative board in the same manner as the above-described new kick board member A. In addition, the length of this newly installed step board B is also formed in the length dimension which the both end surfaces join to the opposing surface of the side girders 12 and 12 of a staircase similarly to the said new kick board member A.
[0016]
  In order to reform the stairs using the newly constructed kick board member A and the newly constructed tread board B constructed as described above, after the new kick board members A and A are constructed on the existing tread boards 13 and 13 adjacent to each other vertically The construction of the new tread B is sequentially performed. In addition, since the construction method is the same even if the new kick board member A is any of the kick board members shown in FIGS. 1A to 1D, the new kick board shown in FIG. The member A will be described. First, as shown by the dotted lines in FIGS. 3 and 4, the new kick plate member A is mounted on the existing footboard 13 on the lower side, and is formed at a right angle to the fixed portion 2. The kick plate portion 1 that is present is set up vertically from the front end of the fixed portion 2.
[0017]
  In this state, by moving and adjusting the position of the fixed portion 2 on the lower existing tread 13 in the front-rear direction, the rear end of the upper end of the kick plate 1 is brought into contact with the front end of the upper existing tread 13 over the entire length.

  At this time, the protrusion width of the upper step board 13 protruding forward from the existing kick board 11 is narrow, and the protrusion width from the kick board section 1 of the fixed part 2 in the new kick board member A to be constructed is the protrusion of the tread board 13. When the width is larger than the width, the rear portion of the fixing portion 2 is appropriately widened and cut to make the projecting width smaller than the projecting width of the tread plate 13. When the height (vertical width) is larger than the vertical width dimension between the upper surfaces of the upper and lower tread plates 13, 13, the upper end portion of the kick plate portion 1 is cut by a desired dimension and the vertical distance between the upper surfaces of the upper and lower tread plates 13, 13 is cut. What is necessary is just to make it become lower than a width dimension.
[0021]
  Thus, the new kick board member A is sequentially constructed on the rear end portion of the existing foot board 13, while the new foot board B is constructed on the existing foot board 13 on which the new kick board member A has already been constructed. The newly installed tread B has a front surface at the lower end of the kick plate 1 of the newly installed kick plate member A in which the tread 3 is superimposed on the existing tread 13 and the rear end face is fixed on the rear end of the tread 13. And a kick-in of a lower newly installed kick plate member A in which a front end curtain plate portion 4 bent at a right angle downward from the front end of the tread plate portion 3 is nailed to the front end surface of the existing tread plate 13 The upper end of the kick plate 1 is brought into contact with the front surface of the upper end of the plate 1 so as to cover it and the lower surface is fixed to the upper surface of the existing tread 13 with an adhesive or a nail. It sticks by hitting.
[0022]
  When constructing the new tread B, the rear end of the tread 3 is cut out by a predetermined width as necessary, so that the front end curtain plate 4 is attached to the front end of the existing tread 13. When the upper end portion of the kick plate portion 1 of the lower new kick plate member A is covered, the rear end surface of the tread plate portion 3 comes into contact with the front surface of the lower end portion of the kick plate portion 1 of the upper new kick plate member A. Adjust the width as follows. Thus, the stairs are reformed by covering all the kick plates 11 and the step plates 13 in the existing stairs with the new kick plate member A and the new step plate B as shown in FIG.
[0023]
  Next, in the above embodiment, as the new kick plate member A, the structure in which the fixed portion 2 bent at a right angle toward the rear is integrally provided at the lower end of the kick plate portion 1 is exemplified. The part and the fixing part may be formed separately and combined so as to be constructed at the time of construction.
[0024]
  FIG. 5 shows an example of the newly installed kick plate member A ′, which is a front laterally long rectangular kick plate 1 ′ and an upward opening that supports the lower end portion of the kick plate 1 ′ inserted into the upper surface of the front end portion. And a fixing member 2 ′ forming a groove 24. In addition, these kick board 1 'and fixing member 2' are the opposite surfaces of the side girders 12 and 12 of the staircases, as in the case of the new kick board member A in the embodiment described above. It is formed in the length dimension joined to.
[0025]
  The fixing member 2 ′ has a narrow substrate portion 21 having a certain thickness and disposed in the length direction toward the length direction of the existing tread plate 11, and the length of the front end side of the substrate portion 21 is long.
