Description

【０００１】
【発明の属する技術分野】
本発明は、門柱やフェンスの支柱等の支柱体に関する。
【０００２】
【従来の技術】
一般に、この種の支柱体の施工には、コンクリート床の仕上げ前に支柱体の下部をコンクリートに埋め込む方法と、コンクリート床の仕上げ後（施工後）に支柱体を床に取り付ける方法とがある。
【０００３】
これらの方法の内、コンクリ−ト床の施工後に床に支柱体を取り付ける技術として特許文献１が公知である。
【０００４】
この特許文献１に開示の技術では、ベース部材に内側部材を固定し、支柱本体を内側部材に被せて支柱本体を内側部材にねじ固定し、床に形成した穴にベース部材と共に支柱本体の下部を配置して、コンクリートで穴を埋める技術が開示されている。
【０００５】
また、コンクリ−ト床の施工後に床に支柱体を取り付ける他の方法として、コンクリート床面にベース部材をアンカーボルト等で固定し、基板に支柱本体をボルトとナットで固定すると共に、ベース部材と支柱本体との固定部をカバー部材で隠す技術が公知である。
【０００６】

【０００７】
【発明が解決しようとする課題】
しかし、特許文献１の技術では、コンクリート床にベース部材が入る大きさの穴を開ける必要があり、その穴の部分のコンクリート床の厚みが薄くなり、その部分の床の強度が低下するという問題がある。更に、床にベース部材よりも大きな面積の穴を開けるためにコンクリートの切削作業に手間が係り、施工し難いという問題がある。
【０００８】
後者の方法のように、ベースプレートを埋めないで床面にアンカーボルト等で固定する場合には、床面の仕上がり状態、例えば、床面に凹凸や傾斜があると柱を垂直に立てることが困難になるという問題がある。
【０００９】
また、支柱体の下部を隠すカバー部材が段差となって、支柱体全体における外観を害するという問題がある。
【００１０】
本発明は、上述した事情に鑑みなされたもので、コンクリート床の施工後に床面に固定でき、施工が容易で且つ外観の良い支柱体の提供を目的とする。
【００１１】
【課題を解決するための手段】
上記目的を達成するために、請求項１に記載の発明は、内側部材と、内側部材に上方から被せて取り付ける支柱本体と、コンクリート床に固定した被締結部材と、裏板と、複数の調節ねじとを備え、内側部材は被締結部材の挿通孔を有する底部と、底部から立設した横断面コ字形状の側壁とを有し、内側部材の底部は側壁の側面開口部から側壁の内側に挿入した締結部材で被締結部材に固定してあり、裏板は内側部材の底部と床面との間に設けてあると共に被締結部材を挿通してあり、調節ねじは内側部材の底部に螺合してあり先端を裏板に当てて内側部材のレベル調節を行なうものであり、支柱本体は下端が床面に当接し且つ内側部材の側壁にねじ固定してあることを特徴とする。
【００１２】
この請求項１に記載の発明では、支柱体の施工は、コンクリート床に被締結部材を固定し、被締結部材を裏板と内側部材の底部に挿通して、内側部材の底部に螺合した調節ねじの先端を裏板に当接させ、調節ねじを締め付けて、底部と裏板との間の寸法を調節した後、内側部材の側壁に設けた開口部から締結部材を挿入し、締結部材を締め付けて床に内側部材を固定する。次に、内側部材の上端から支柱本体を被せて、内側本体の側壁にねじで支柱本体を固定する。
【００１３】
本発明によれば、支柱体の下部やベース部材を埋め込むための穴を形成しないので、コンクリート床面の強度の低下を防止できる。
【００１４】
内側部材の側壁には開口部が設けてあり、内側部材の開口部から底部に挿通した被締結部材に締結部材を装着する作業ができるので、作業性が良い。
【００１５】
支柱本体の下端は床面に当接して、内側部材や被締結部材を覆っているので、段差が無く、外観がよい。更に、従来用いられていたカバー部材が必要無く、部品点数を少なくできる。
【００１６】
【００１７】
【００１８】
【００１９】
【００２０】
コンクリート床に凹凸がある場合や、床面が傾斜している場合にも、底部の複数の箇所において、内側部材の底部に螺合した調節ねじの先端を裏板に当接させて、底部と裏板との間の寸法を調節することにより、内側部材のレベル調節（鉛直や傾斜の調節）が簡単にできる。
【００２１】
【発明の実施の形態】
以下に、添付図面の図１〜図４を参照して本発明の実施の形態を詳細に説明する。図１は図４に示す支柱体の分解斜視図であり、図２は図４のＡ−Ａ断面図であり、図３は図４のＢ―Ｂ断面図であり、図４は本発明の実施の形態に係る支柱体を用いた門扉において、床を切断して示す正面図である。
【００２２】
本実施の形態に係る支柱体１は、門扉の吊元柱であり、本実施の形態では支柱体１は、マンション等のコンクリート床に施工されるものであり且つ図４に示すようにフェンスの柱を兼ねている。
【００２３】
支柱体１は、内側部材３と、支柱本体５と、床７に固定される被締結部材９とを備えており、コンクリートの仕上げ後に、いわゆる後付けにより施工されるものである。
【００２４】
内側部材３は、上面が開口した中空の略直方体形状に形成されており、四側面の内の一側面に開口部１１が形成されている。内側部材３の底部１２は、平面視矩形であり、その対角線上には被締結部材９の挿通孔１３が形成されている。内側部材３の側壁１６には、ねじ孔１５が形成されており、支柱本体５をねじ１７で止めるようになっている。
【００２５】
支柱本体５は、中空を有する略四角柱形状であり、下端１９が開口されており、下端１９から内側部材３に挿入されている。また、支柱本体５の下端１９は床面７ａに当接して密着されている。
【００２６】
尚、支柱本体５には、フェンスの横桟２１の取付金具２２がビス止めされている。
【００２７】
被締結部材９は、周囲全体にねじが形成されたいわゆる寸切りボルトであり、上部を床から突設させて床７に埋め込まれている。この被締結部材９の上部は内側部材３の底部１２にある挿通孔１３に挿通されて、ナット２３が締結されることにより内側部材３を被締結部材９に固定している。
【００２８】
床７はコンクリート製であり、床にドリルで開けた穴２５に被締結部材９を挿入してあり、穴２５内に注入した樹脂製接着剤２７で固定してある。樹脂製接着剤２７は本実施の形態ではエポキシ樹脂接着剤である。
【００２９】
次に、本実施の形態に係る支柱体１の施工及び作用について説明する。支柱体１の施工は、仕上げ後のコンクリート床７にドリルで穴２５を開け、穴２５に被締結部材９を挿入し、且つ穴２５に樹脂製接着剤２７を注入して樹脂製接着剤２７を固化させる。これにより被締結部材９が床７に固定される。被締結部材９の固定は、床７に開けた穴２５に挿入して樹脂材で固定するので、アンカー等を用いる場合に比較して簡単にでき、作業性が良い。
【００３０】
その後、被締結部材９の上部に内側部材３の挿通孔１３を挿通して底部１２を床面７ａに載置する。次に、内側部材３の底部１２から突設している被締結部材９の上部にナット２３を螺合して内側部材３の底部１２を床面に固定する。ナット２３の締結は、内側部材３の側面に形成された開口部１１を介して行なう。内側部材３の開口部１１から手をいれて締結作業ができるので、ナット２３の締結作業が容易である。これにより、内側部材３が床７に固定される。
【００３１】
次に、内側部材３の上端から支柱本体５の下端１９を挿入して、支柱本体５を内側部材３に被せる。支柱本体５はその下端１９を床面７ａに当接させて、内側部材３を完全に覆う。そして、支柱本体５の側面からねじ１７を螺合し、支柱本体５を内側部材３にねじ止めする。支柱本体５のねじ止めは、内側部材の３面の側壁１６に対応して３面で固定するので、支柱本体５は内側部材３に強固に固定される。
【００３２】
本実施の形態では、コンクリート製の床７には被締結部材９を埋める穴２５のみを形成すればよく、コンクリート製の床７に支柱本体５の下部を埋め込むような大きい面積の穴を形成しなくて済むので、コンクリート製床７の強度の低下を招くおそれが無い。
【００３３】
内側部材３はコンクリートに埋め込んだ被締結部材９に固定するから、コンクリート製の床７に強固に固定でき、例えば人が寄りかかる等して支柱体１が傾くのを防止できる。
【００３４】
内側部材３の一側面には開口部１１が設けてあり、底部１２に挿通した被締結部材９に内側部材３の開口部１１から締結部材２３を装着する作業ができるので、作業性が良い。
【００３５】
内側部材３の固定後は、床７に固定した内側部材３に支柱本体７を被せて内側部材３に支柱本体７をねじ止めするだけなので、施工が容易である。
【００３６】
支柱本体５の下端１９は床面７ａに当接して、内側部材３や被締結部材９を覆っているので、支柱本体５のみの外観を得ることができ意匠の自由度が高いと共に、支柱体１に段差が無く、外観がよい。
【００３７】
以下に、本発明の他の実施の形態を説明するが、以下に説明する実施の形態では、上述した実施の形態と同一の作用効果を奏する部分には同一の符号を付することにより、その部分の詳細な説明を省略し、上述した実施の形態と異なる点を主に説明する。
図５は第２実施の形態に係る支柱体１において、支柱本体５を除いた状態を示す斜視図である。この第２実施の形態では、内側部材３の底部１２と床面７ａとの間に裏板３１を設けたものである。裏板３１には、底部１２と同様に被係止部材９の挿通孔が形成されており、被係止部材９は裏板３１と底部１２の挿通孔１３に挿通されてナット２３により締結される。また、底部１２には、その各コーナ部にレベル調節ねじ３３が螺合されており、レベル調節ねじ３３の先端が裏板１２に当接されている。各コーナ部のレベル調節ねじ３３を螺進して、内側部材３のレベル（水平や傾斜）を調節するようになっている。
【００３８】
この第２実施の形態では、床面７ａが傾斜していたり、床面７ａに凹凸がある場合にも、各レベル調節ねじ３３の螺進量を調節することにより、内側部材３を鉛直に施工したり、傾斜させて施工することが容易にできる。
【００３９】
本発明は、上述した実施の形態に限定されず、本発明の要旨を逸脱しない範囲で種々変形可能である。
例えば、被締結部材９は２本設けることに限らず、３本、４本等いくつでもよい。
【００４０】
被締結部材９を床７の穴２５に充填する樹脂製接着剤は、エポキシ樹脂に限らず、他の樹脂製接着剤でもよい。
【００４１】
支柱体１は門扉の吊元側柱に限らず、門柱やフェンスの支柱であってもよい。
【００４２】
【００４３】
【００４４】
第２実施の形態において、調節ねじ３３は３箇所に設けるものであってもよく、その数は限定されない。
【００４５】
【発明の効果】
請求項１に記載の発明によれば、支柱本体や従来のベースプレートを埋め込む穴を形成しないので、コンクリート床面の強度の低下を招くことを防止できる。
【００４６】
内側部材の側壁には開口部が設けてあり、内側部材の開口部から底部に挿通した被締結部材に締結部材を装着する作業ができるので、内側部材の固定作業がし易く、作業性が良い。
【００４７】
支柱本体の下端は床面に当接して、内側部材や被締結部材を覆っているので、段差が無く、外観がよいと共に、支柱本体のみの外観を得ることができるので、意匠の自由度が高い。
【００４８】
【００４９】
【００５０】
コンクリート床に凹凸がある場合や、床面が傾斜している場合にも、内側部材の底部に螺合した調節ねじの先端を裏板に当接させて、調節ねじの螺進量を調節することにより、内側部材のレベル調節が簡単にできる。
