Description

【０００１】
【発明の属する技術分野】
本発明は、建物の屋上やベランダ等に設置される手摺りの取付装置に関するものである。
【０００２】
【従来の技術及びその課題】
従来使用されている手摺りの取付装置として、例えばベランダの外縁部に突設されているコンクリート製手摺り基台に、コ字枠状に形成したアンカー部材を跨嵌させて、その手摺り基台を室内外方向に貫通する通しボルトとナットにより固定し、アンカー部材の上面側に手摺り支柱の下端を当接させて、ビスやボルトで固着するようにしたものがあるが、この取付装置では、部材点数が多く、取付けに非常に手間がかかり、施工費が高くつく上に、手摺り支柱の下端がアンカー部材上にビスやボルトで連結されているだけであるため、アンカー部材に対して十分な連結強度が得られず、手摺り支柱に繰り返し横荷重がかかることによりビスやボルトが緩み易く、手摺り支柱の取付状態が不安定となるおそれがあった。
【０００３】
本発明は、上記の問題に鑑み、部材点数が少なく、取付作業が簡単に行えて、施工費を安くできると共に、アンカー部材に対する手摺り支柱下端部の取付強度を増大し得る手摺りの取付装置を提供することを目的とする。
【０００４】
【課題を解決するための手段】
請求項１に係る発明は、手摺り支柱２を嵌合させる補強支柱６と、この補強支柱６の下端部に固着される取付基板７と、この取付基板７に取付け固定される棒状アンカー部材８又は９とからなり、コンクリート製手摺り基台１に穿設したアンカー用穴１３に棒状アンカー部材８又は９を挿入し、前記アンカー用穴１３に充填した溶融合成樹脂１５によって棒状アンカー部材８又は９をアンカー用穴１３に固着してなる手摺りの取付装置であって、補強支柱６の下端部に力骨２０を嵌合し、この力骨２０の下端部を補強支柱６の下端から僅かに突出させ状態で、力骨２０の下端面を取付基板７上の中央部に当接させ、この状態で力骨２０の下端周縁部を取付基板７に溶接すると同時に、補強支柱６の下端部を力骨２０と取付基板７とに溶接してなることを特徴とする。
【０００６】
請求項２は、請求項１に記載の手摺りの取付装置において、取付基板７に設けた複数のボルト挿通孔７ａに夫々ボルト材からなる棒状アンカー部材８を挿通し、取付基板７を挟んでその上下両側から各棒状アンカー部材８に螺合した一対のナット１０，１０で取付基板７を挟着して取付基板７と各棒状アンカー部材８とを一体的に結合してなることを特徴とする。
【０００７】
請求項３は、請求項１又は２に記載の手摺りの取付装置において、取付基板７の室内外方向中央部にボルト材又は鉄筋からなる棒状アンカー部材８又は９固着し、取付基板７の室内外両端部に夫々ねじ孔２２を設け、両ねじ孔２２，２２には夫々下端が手摺り基台１上面に当接する調整用ボルト１９を螺合貫通させてなることを特徴とする。
【０００８】
請求項４は、請求項３に記載の手摺りの取付装置において、棒状アンカー部材８又は９には手摺り基台１上面に載置される敷板２３を挿通し、この敷板２３上面に各調整用ボルト１９の下端を当接させるようにしてなることを特徴としている。
【０００９】
請求項５は、請求項１〜４の何れかに記載の手摺りの取付装置において、補強支柱６に嵌合された手摺り支柱２の下端部及びその周辺の部材を覆うカバー部材１２を、手摺り支柱２に嵌合して取り付けてなることを特徴とする。
【００１０】
【発明の実施の形態】
図１は建物のベランダに設置された手摺りＴを室外側から見た正面図であり、図２は、手摺りＴの取付装置１１の縦断面斜視図である。また図３の（Ａ）は、手摺りＴの取付装置１１の縦断面図、（Ｂ）は（Ａ）のＸ−Ｘ線断面図である。この手摺りＴは、ベランダの外縁部に突設されたコンクリート製手摺り基台１に手摺り支柱２を一定間隔おきに立設し、各手摺り支柱２に上下横枠３，４を連結すると共に、上下横枠３，４間に縦桟５を一定間隔おきに配設してなるものである。手摺り支柱２は、アルミ押し出し型材からなる角筒材である。
【００１１】
手摺りの取付装置１１は、手摺り支柱２を嵌合させる鉄製の補強支柱６と、この補強支柱６の下端部に固着される鉄製の取付基板７と、この取付基板７に取り付けられる両側一対の棒状アンカー部材８，８と、取付基板７を挟んでその上下両側から各棒状アンカー部材８に螺合される一対のナット１０，１０と、取付基板７上に固着突設され、補強支柱６の下端部が嵌合される力骨２０と、手摺り支柱２の下端取付部分を覆うカバー部材１２と、から構成される。
【００１２】
補強支柱６は、手摺り支柱２が外嵌可能な横断面長方形の角パイプ材からなるもので、その高さは、手摺り支柱２の高さの１／３〜１／４で、例えば３０ｃｍ程度である。取付基板７は、厚手の鉄板を図３の（Ｂ）に示すような長方形に形成したもので、この取付基板７の上面中央部に力骨２０が固着突設されると共に、この力骨２０に補強支柱６が嵌合固着されている。力骨２０は、補強支柱６に嵌合可能な厚手の鉄板片からなるもので、この力骨２０を設けたことによって、取付基板７に対する補強支柱６の取付強度が増大し、補強支柱６に相当大きな横荷重が作用しても、その補強支柱６がその付け根部分から折損するようなおそれがない。
【００１３】
この補強支柱６を取付基板７上に固着突設する際には、補強支柱６の下端部に力骨２０を嵌合し、この力骨２０の下端部を補強支柱６の下端から僅かに突出させ状態で、力骨２０の下端面を取付基板７上の中央部に当接させ、この状態で力骨２０の下端周縁部を取付基板７に溶接すると同時に、補強支柱６の下端部を力骨２０と取付基板７とに溶接し、こうすることによって補強支柱６と力骨２０と取付基板７とを簡単な作業で有効に一体結合することができる。尚、この際の溶接部を図２及び図３にＷ１で示す。
【００１４】
各棒状アンカー部材８は、ボルト材（ねじ棒）からなるもので、取付基板７の室内外両端部に設けられたボルト挿通孔７ａ，７ａに夫々挿通され、取付基板７を挟んでその上下両側から各棒状アンカー部材８に螺合される一対のナット１０，１０を締め付けて取付基板７を挟着することにより、取付基板７と各棒状アンカー部材８とが一体的に結合される。
【００１５】
カバー部材１２は、図２及び図３に示すように、周側壁部１２ａと上壁部１２ｂとからなる金属製又は合成樹脂製のもので、上壁部１２ｂに手摺り支柱挿通用開口部１２ｏが形成されている。
【００１６】
図４の（Ａ）は力骨２０を備えていない取付装置１１′の縦断面図、（Ｂ）は（Ａ）のＸ−Ｘ線断面図である。ここに示す取付装置１１′は、力骨２０を備えていない点が異なるだけで、それ以外は図２及び図３に示す取付装置１１を全く同じ構成であるため、同一部材には同一符号を付して、説明を省略する。
【００１７】
次に、上記手摺りの取付装置１１により手摺りＴを取り付ける方法について、図５〜図７を中心に他の図面を参照しながら説明する。
【００１８】
先ず、図５に示すように、コンクリート製手摺り基台１の手摺り支柱設置箇所に、取付装置１１の棒状アンカー部材８，８が嵌合するアンカー用穴１３，１３を鉛直方向に穿設し、そして各アンカー用穴１３には、例えばエポキシ樹脂のような熱可塑性樹脂からなる溶融した合成樹脂１５を充填する。
【００１９】
そして、手摺り基台１の各手摺り支柱設置箇所に穿設したアンカー用穴１３，１３の上方に図５に示すように取付装置１１を持ち来たし、その取付基板７の両端部で夫々上下一対のナット１０，１０で保持されて垂下した棒状アンカー部材８，８をアンカー用穴１３，１３に挿入嵌合し、図６に示すような状態とする。この際、各棒状アンカー部材８に螺合されている各一対のナット１０，１０の下側のナット１０と手摺り基台１の上面１ａとの間に若干隙間ができるようにするのがよい。
【００２０】
この時、各アンカー用穴１３とこれに挿入嵌合された棒状アンカー部材８との隙間全体に溶融樹脂１５が行き渡り、この溶融樹脂１５が硬化することによって、各棒状アンカー部材８が各アンカー用穴１３に固着される。この溶融樹脂は、夏季では充填後５〜１０分程度で硬化し、また冬季には１〜３時間で硬化するから、棒状アンカー部材８をアンカー用穴１３に挿入した後、この樹脂が硬化しない間に、取付基板７のボルト挿通孔７ａ及びアンカー用穴１３との隙間を利用して各棒状アンカー部材８を動かしながら適宜に鉛直姿勢にする。
【００２１】
各アンカー用穴１３内の合成樹脂１５が硬化して各棒状アンカー部材８がアンカー用穴１３に固着されたならば、取付基板７を挟んでその上下両側から各棒状アンカー部材８に螺合される各一対のナット１０，１０を締め付けて取付基板７を挟着し、取付基板７と両側一対の棒状アンカー部材８，８とを一体的に結合し、これによって補強支柱６を手摺り基台１に固定し、補強支柱６を鉛直位置に保持することができる。
【００２２】
この時、補強支柱６が室内側又は室外側へ傾いているようであれば、各一対のナット１０，１０を緩めて、取付基板７の両端部側を交互に上げ下げしながら、補強支柱６が鉛直姿勢になるように取付基板７をレベル調整した後、各一対のナット１０，１０を締め付け、上記のように取付基板７と両側一対の棒状アンカー部材８，８とを一体的に結合して、補強支柱６を鉛直位置に保持する。
【００２３】
また、コンクリート製手摺り基台１の上面が水切り勾配を形成している場合には、補強支柱６が鉛直姿勢となるように調整基板７をレベル調整した状態で、この調整基板７と手摺り基台１の上面、即ち傾斜面との間の隙間に適当なスペーサを介在させ、この状態でナット１０を締め付けることによって、上記同様に補強支柱６を鉛直姿勢に保持することができる。
【００２４】
上記のように各取付装置１１の補強支柱６が鉛直姿勢に保持されたならば、図６及び図７に示すように、各取付装置１１の補強支柱６に手摺り支柱２を嵌合しし、ビス１８によって手摺り支柱２の下端所要部を補強支柱６に固定し、これにより手摺り支柱２を手摺り基台１上に立設する。
【００２５】
この際、図７に示すように手摺り支柱２にあらかじめカバー部材１２を嵌合しておいて、この手摺り支柱２を補強支柱６に嵌合して固定した後、そのカバー部材１２を手摺り支柱２の下端部まで下降すれば、このカバー部材１２によって、手摺り支柱２の下端部、取付基板７、棒状アンカー部材８の上端突出部、ナット１０が覆い隠されてしまうから、外観上の体裁、見栄えが良くなると共に、雨水等がそれらに直接かからず、防錆効果がある。
【００２６】
上記のようにして手摺り支柱２をコンクリート製手摺り基台１上の所定位置に立設したならば、各手摺り支柱２に上下横枠３，４を連結し、上下横枠３，４間に縦桟５を一定間隔おきに配設することによって、図１に示すような手摺りＴが設置される。
【００２７】
図８の（Ａ）は、他の実施形態による取付装置２１を示す一部断面側面図であり、（Ｂ）はその平面図である。この取付装置２１は、図２及び図３に示す取付装置１１と殆ど同様であるが、取付基板７の室内側端部に２つの棒状アンカー部材８を取り付けた点が取付装置１１と相違する。即ち、取付基板７の室外側端部に１つのボルト挿通穴７ａを設け、その室内側端部には２つのボルト挿通穴７ａ，７ａを設け、これらのボルト挿通孔７ａ，７ａに、夫々ボルト材からなる棒状アンカー部材８を挿通すると共に、取付基板７を挟んでその上下両側から各棒状アンカー部材８に一対のナット１０，１０を螺合したものである。
【００２８】
このように取付基板７の室内側端部に２つの棒状アンカー部材８が取り付けることによって、手摺り基台１に対する取付基板７の取付強度は、取付基板７の室外側端部より室内側端部の方が大きくなるから、手摺りに対し室内側から人や物がもたれ掛かるなどして頻繁に室外方向への横荷重が作用しても、その横荷重に十分耐えることができる。また、取付基板７を手摺り基台１上に３点で支持することになるため、取付基板７の取付状態が安定する。尚、取付基板７の室内側に３つ以上に棒状アンカー部材８を取り付けてもよい。
【００２９】
図９の（Ａ）は、本発明の更に他の実施形態による取付装置３１を示す一部断面側面図であり、（Ｂ）はその平面図である。この取付装置３１は、取付基板７の室内外方向中央部に鉄筋からなる棒状アンカー部材９の上端部を溶接によって固着し、取付基板７の室内側端部及び室外側端部にねじ孔２２，２２を設け、両ねじ孔２２，２２に夫々調整用ボルト１９を螺合貫通させるようにすると共に、取付基板７の下側にあって手摺り基台１の上面に載置される鉄板製の敷板２３を棒状アンカー部材８に挿通し、この敷板２３の上面に各調整用ボルト１９の下端を当接させるようにしている。敷板２３は、その挿通孔２３ａに棒状アンカー部材８を挿通させる。他の構成については、前記取付装置１１と同様である。
【００３０】
この取付装置３１の使用にあたっては、前記取付装置１１と同様に、手摺り基台１に穿設したアンカー用穴１３に溶融樹脂１５を充填し、このアンカー用穴１３の上方に取付装置３１を持ち来たして、その取付基板７の中央部から垂下する棒状アンカー部材９をアンカー用穴１３に挿入嵌合し、取付基板７の下側にある敷板２３を手摺り基台１の上面に載置する。尚、取付基板７と敷板２３との間に介在するパッキン２４を棒状アンカー部材９に挿通させておいてもよい。
【００３１】
しかして、アンカー用穴１３内の合成樹脂１５が硬化して棒状アンカー部材８がアンカー用穴１３に固着されたならば、各調整用ボルト１９を締め付けて、そのボルト１９の下端を敷板２３の上面に圧接することにより、取付基板７を、調整用ボルト１９及び敷板２３を介して手摺り基台１の上面に支持する。この時、補強支柱６が室内側又は室外側へ傾いているようであれば、両方の調整用ボルト１９，１９あるいはその何れか一方をねじ込んだり、緩めたりしながら、補強支柱６が鉛直姿勢になるように取付基板７をレベル調整することによって、補強支柱６を鉛直位置に保持することができる。
【００３２】
この取付装置３１では、補強支柱６は、取付基板７を一体に固着した棒状アンカー部材８が樹脂１５によりアンカー用穴１３に固着されて、手摺り基台１に固定されと共に、両側の調整用ボルト１９，１９の少なくとも一方が敷板２３上面に圧接されるから、１本の棒状アンカー部材８でも、手摺り基台１に安定状態に立設され、そして両調整用ボルト１９，１９を適宜に回すことにより取付基板７をレベル調整して補強支柱６の直立姿勢を矯正することができる。
【００３３】
上記敷板２３及びパッキン２４は省略することができる。しかし、取付基板７の下側にあって手摺り基台１の上面に載置される敷板２３を使用した場合には、調整用ボルト１９の下端がこの敷板２３上面に当接されるから、この調整用ボルト１９による取付基板７のレベル調整を的確且つ有効に行なうことができる。
【００３４】
以上説明した手摺りの取付装置１１，１１′，２１，３１は、何れの装置も部品点数が少なく、しかも各アンカー部材８，９がボルト材又は鉄筋からなる棒状の部材であって、補強支柱６及び取付基板７と共に極めてシンプルな構成部材であるため、使用に際しては、コンクリート製手摺り基台１にアンカー用穴１３を穿設しておけば、あとは簡単且つ容易に取付作業が行えて、施工費を安くでき、また、各棒状アンカー部材８，９はアンカー用穴１３内に充填した溶融合成樹脂１５によってアンカー用穴１３内に固着されるから、アンカー部材８，９を手摺り基台１に迅速且つ強固に固定させることができる。
【００３５】
尚、図９に示す取付装置１１では、取付基板の中央部に固着される棒状アンカー部材として、鉄筋からなる棒状アンカー部材９を用いているが、ナット材からなる棒状アンカー部材８を使用してもよい。
【００３６】
【発明の効果】
請求項１に係る発明の手摺りの取付装置は、手摺り支柱を嵌合させる補強支柱と、補強支柱の下端部に固着される取付基板と、取付基板に取付け固定される棒状アンカー部材とからなり、コンクリート製手摺り基台に穿設したアンカー用穴に棒状アンカー部材を挿入し、アンカー用穴に充填した溶融樹脂によって棒状アンカー部材をアンカー用穴に固着してなるもので、各アンカー部材が棒状部材であって、補強支柱及び取付基板と共に極めてシンプルな構成部材からなるため、使用に際しては、手摺り基台にアンカー用穴を穿設すれば、あとは簡単且つ容易に取付作業を行なうことができ、従って施工費を極力安くできると共に、アンカー部材に対する手摺り支柱下端部の取付強度を増大できる。また、各棒状アンカー部材は、合成樹脂によってアンカー用穴内に固着されるから、アンカー部材を手摺り基台に迅速且つ強固に固定できる。
【００３７】
また本発明によれば、補強支柱の下端部を、取付基板上に固着突設される力骨に嵌合して取付基板に固着することによって、取付基板に対する補強支柱の取付強度が増大し、補強支柱に相当大きな横荷重が作用しても、その補強支柱がその付け根部分から折損するようなおそれがない。さらに本発明によれば、この補強支柱を取付基板上に固着突設する際には、補強支柱の下端部に力骨を嵌合し、この力骨の下端部を補強支柱の下端から僅かに突出させ状態で、力骨の下端面を取付基板上の中央部に当接させ、この状態で力骨の下端周縁部を取付基板に溶接すると同時に、補強支柱の下端部を力骨と取付基板とに溶接し、こうすることによって補強支柱と力骨と取付基板とを簡単な作業で有効に一体結合することができる。
【００３８】
請求項２に記載のように、取付基板に設けた複数のボルト挿通孔に夫々ボルト材からなる棒状アンカー部材を挿通し、取付基板の上下両側から各棒状アンカー部材に螺合した一対のナットで取付基板を挟着して取付基板と各棒状アンカー部材とを一体的に結合してなる取付装置によれば、補強支柱が傾いている時には、各一対のナットを緩めて補強支柱が鉛直姿勢になるように取付基板をレベル調整した後、各一対のナットを締め付けることにより、取付基板と棒状アンカー部材とを一体的に結合して、補強支柱を鉛直姿勢に保持することができる。
【００３９】
請求項３に記載のように、取付基板の室内外方向中央部に棒状アンカー部材を固着し、取付基板の室内外両端部に夫々ねじ孔を設け、両ねじ孔に夫々下端が手摺り基台上面に当接する調整用ボルトを螺合貫通させた取付装置によれば、取付基板を一体に固着した棒状アンカー部材が手摺り基台１に固定されと共に、両側の調整用ボルトの少なくとも一方が敷板上面に圧接されるから、１本の棒状アンカー部材でも、補強支柱は手摺り基台に安定状態に立設され、そして両調整用ボルトを回すことにより取付基板をレベル調整して補強支柱の姿勢を矯正することができる。
【００４０】
請求項４に記載のように、棒状アンカー部材に手摺り基台上面に載置される敷板を挿通し、この敷板上面に各調整用ボルトの下端を当接させるようにすれば、調整用ボルトの下端が敷板上面に当接されるから、この調整用ボルトによる取付基板のレベル調整を的確且つ有効に行なうことができる。
【００４１】
請求項５に記載のように、補強支柱に嵌合された手摺り支柱の下端部及びその周辺の部材を覆うカバー部材を手摺り支柱に嵌合して取り付けることによって、手摺り支柱の下端部、取付基板棒状アンカー部材の上端突出部、ナット等が覆い隠されてしまうから、外観上の体裁、見栄えが良くなると共に、雨水等がそれらに直接かからず、防錆効果がある。
