Description

【0001】
【発明の属する技術分野】
本発明は、一般家屋等の建築物における屋根の建造,修理,点検作業に使用する屋根工事用作業足場とその設置方法に関する。
【0002】
【従来の技術】
一般家屋等の建築物の屋根を建造,修理をする場合、この屋根は任意の角度の勾配を有しているため、作業者が屋根面に沿って縦横に歩行するのが困難で、作業姿勢も不安定となる。従って作業性が悪く、最悪の場合は作業者が転倒して地上に落下する危険もある。この為、作業者が屋根面上で比較的安全に歩行したり、諸作業を行なえる簡易の作業足場として例えば特開平5−33480号公報に示すもの、又は図23に示す構造のものが開発されている。これらの作業足場に共通するところはいずれも屋根面上に縦方向のパイプと横方向のパイプとを井桁状に組付けたもので、これらのパイプを踏台として使用している。例えば、図23に示す作業足場としては建築物Bの周囲に枠組足場Cを起立させ、同時に屋根面A上には多数の縦方向のパイプ支柱aと横方向のパイプ支柱bとを縦横に組付けて屋根工事用の作業足場Dを形成させたものである。そして屋根面Aの建造,修理等の作業を行なう場合は枠組足場Cを通って屋根工事用の作業足場Dに移動し、この作業足場Dを利用して歩行したり、諸作業を行なうものである。
【0003】
【発明が解決しようとする課題】
上記従来の屋根工事用の作業足場Dでは作業者が横方向のパイプ支柱b上を歩行するだけであるから、踏台としては不安定なものであり、歩行中又は作業中に作業者が踏台を踏みはずしたり、すべって転倒する危険がある。又各パイプ支柱a,bには手摺が設けられていないので余計に作業者が転倒しやすく、地下に落下して人身事故をおこす危険がある。そこで、本発明の目的は、屋根面上の歩行、作業中に作業者が転倒したり、地下に落下するのを防止し、安全な作業が行なえ、人身事故の発生を防止できる屋根工事用作業足場及びその設置方法を提供することである。
【0004】
【課題を解決するための手段】
上記の目的を達成するため、本発明の一つの手段は、 タラップと、タラップの片側又は両側に起立する手摺と、タラップの側部に設けた足場板支持金具と、タラップの側部に当該タラップと直交する方向に配置する足場板と、足場板の片側又は両側に起立する手摺とを備え、屋根面の勾配に合せて角度調整しながら当該屋根面上にタラップを縦方向に配設し、タラップの角度に合せて角度調整しながら足場板支持金具を水平に配置し、足場板支持金具に足場板の端部を結合しながら当該足場板を屋根面上に水平方向に向けて配設し、更にタラップと足場板にそれぞれ手摺を角度調整しながら垂直に起立させた屋根工事用作業足場において、上記足場板支持金具を水平な支持桿と、支持桿の端部に設けた手摺差し込み用のソッケットと、支持桿の中間に下方に向けて設けた支持片と、支持片に形成した複数の取付孔とで構成し、支持桿の一端を側桁の側部に枢着させ、タラップの角度に応じて支持片を任意の取付孔を選択的に利用して側桁に結合させていることを特徴とする。
【0005】
同じく他の手段は、 タラップと、タラップの片側又は両側に起立する手摺と、タラップの側部に設けた足場板支持金具と、タラップの側部に当該タラップと直交する方向に配置する足場板と、足場板の片側又は両側に起立する手摺とを備え、屋根面の勾配に合せて角度調整しながら当該屋根面上にタラップを縦方向に配設し、タラップの角度に合せて角度調整しながら足場板支持金具を水平に配置し、足場板支持金具に足場板の端部を結合しながら当該足場板を屋根面上に水平方向に向けて配設し、更にタラップと足場板にそれぞれ手摺を角度調整しながら垂直に起立させた屋根工事用作業足場において、上記足場板支持金具が菊座型の板クラッチと、板クラッチの端部に結合した水平な支持桿と、支持桿の端部に設けた手摺差し込み用のソケットとで構成させたことを特徴とする。
【0006】
上記各手段においては、 タラップが一対の側桁と、側桁間に上下方向に沿って隔設された複数のステップとで構成し、ステップの上面を弯曲させると共に当該上面に滑り止めを施すことが好ましい。
【0007】
この場合、 側桁の下方に高さ調整自在なジャッキを設け、このジャッキを側桁の側面に結合したナットとナットに上下移動自在に螺合したねじ桿とで構成させているのが好ましい。
【0008】
更に、本発明の別の手段は、 タラップと、タラップの片側又は両側に起立する手摺と、タラップの側部に設けた足場板支持金具と、タラップの側部に当該タラップと直交する方向に配置する足場板と、足場板の片側又は両側に起立する手摺とを備え、屋根面の勾配に合せて角度調整しながら当該屋根面上にタラップを縦方向に配設し、タラップの角度に合せて角度調整しながら足場板支持金具を水平に配置し、足場板支持金具に足場板の端部を結合しながら当該足場板を屋根面上に水平方向に向けて配設し、更にタラップと足場板にそれぞれ手摺を角度調整しながら垂直に起立させた屋根工事用作業足場において、上記足場板支持金具を側桁に起立させた支持パイプと、支持パイプに枢着した回転自在な支持枠と、支持枠に形成した複数の調整孔と、支持枠に起立する引掛片とで構成し、上記任意の調整孔を介してボルトを上記支持パイプに挿入することにより選択された調整孔に対応して上記支持枠の角度を調整させることを特徴とする。
【0009】
この場合、タラップが一対の側桁と、側桁間に上下方向に沿って隔設された複数のステップとで構成し、 側桁の下方に高さ調整自在なジャッキを設け、このジャッキを側桁受け部材と、側桁受け部材の下部にヒンジ結合したねじ筒と、ねじ筒内に上下移動自在に螺合したねじ桿とで構成させているのが好ましい。
【0010】
同じく、更に別の手段は、 タラップと、タラップの片側又は両側に起立する手摺と、タラップの側部に設けた足場板支持金具と、タラップの側部に当該タラップと直交する方向に配置する足場板と、足場板の片側又は両側に起立する手摺とを備え、屋根面の勾配に合せて角度調整しながら当該屋根面上にタラップを縦方向に配設し、タラップの角度に合せて角度調整しながら足場板支持金具を水平に配置し、足場板支持金具に足場板の端部を結合しながら当該足場板を屋根面上に水平方向に向けて配設し、更にタラップと足場板にそれぞれ手摺を角度調整しながら垂直に起立させた屋根工事用作業足場において、上記タラップを一対の側桁と、上記側桁間に隔設した複数のステップで平行四辺形に構成し、上記足場板支持金具を上記ステップに結合した水平な支持桿と、当該支持桿の両端に設けた手摺挿入用のソケットとで構成し、更に下方のステップに扇形の取付片を設け、この取付片に複数のピン孔を形成し、上記任意のピン孔を介してピンを側桁に挿入し、選択されたピン孔に対応して側桁の角度を調整することを特徴とする。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態を図にもとづいて説明する。図1乃至図9は本発明の一実施の形態を示し、
図10乃至図11、図12乃至図14、及び20は他の実施の形態を示す。
【0012】
各実施の形態に係る屋根工事用作業足場の基本構造と設置方法は、同じであり、例えば図1乃至図13に示すように、タラップ1と、タラップ1の片側又は両側に起立する手摺5と、タラップ1の側部に設けた足場板支持金具7と、タラップ1の側部に当該タラップ1と直交する方向に配置する足場板10と、足場板10の片側又は両側に起立する手摺11とを備え、屋根面Aの勾配に合せて角度調整しながら当該屋根面A上にタラップ1を縦方向に配設し、タラップ1の角度に合せて角度調整しながら足場板支持金具7を水平に配置し、足場板支持金具7に足場板10の端部を結合しながら当該足場板10を屋根面A上に水平方向に向けて配設し、更にタラップ1と足場板10にそれぞれ手摺5を角度調整しながら垂直に起立させるものである。
【0013】
そして、上記の方法の実施に使用される屋根工事用作業足場は、例えば、図1乃至図3に示すように、屋根面Aの勾配に合せて当該屋根面A上に縦方向に配設した角度調整自在なタラップ1と、タラップ1の片側又は両側に起立させた角度調整自在な手摺5と、タラップ1の側部に角度調整自在な足場板支持金具7を介して水平方向に結合した足場板10と、足場板10の片側又は両側に起立させた手摺11とからなるものである。以下、更に詳しく説明する。一般家屋等の建築物の周囲と屋根面上に枠組足場Cと屋根工事用作業足場Eを設置し、屋根面A上の建造,修理を行なう場合には枠組足場Cを昇って屋根工事用作業足場Eに移動する。作業足場Eはタラップ1と、タラップ1上に起立させた手摺5と、タラップ1の側部に足場板支持金具7を介して水平方向に結合した足場板10と、足場板10上に起立した手摺5とを備え、作業者はタラップ1を介して屋根面Aの上下方向ら歩行し、足場板10を介して屋根面Aの横方向に歩行する。この際、タラップ1は水平なステップ13と手摺5を備えているから歩行が安全であり、足場板10は巾広で水平であると共に手摺11を備えているからやはり水平方向の歩行が安全であり、作業姿勢も安定し、その結果、作業者が屋根面A上で転倒したり、あるいは屋根面A上から地上に落下するのが防止される。
【0014】
タラップ1は図3乃至図4に示すように、左右一対の側桁12と、側桁12間に上下方向に沿って隔設した複数のステップ13とで構成している。各側桁12の上下端にはピン孔を形成した差込片31が設けられ、この差込片31を介して他の側桁12が着脱自在に接続できるようになっている。
【0015】
ステップ13は、図7又は図8に示すように、水平部32と弯曲部33とからなる本体と、本体の上面に刻設した多数のリブからなる滑り止め14が形成されている。
【0016】
図7のステップ13は本体の下方に複数の取付片34,35を設けて例えば側桁12、12間の支柱に結合しても良く、図8に示すように本体の下部に補強部36を設けても良い。
【0017】
ステップ13の両端は側桁12の内側に固定しても良い。
【0018】
ステップ13は図8、図9に示すようにタラップ1、いいかえれば側桁12の角度に応じて角度が変化するが、その上面13aのいずれかの位置の一部は常に水平な踏面となっており、作業者の足Pの裏側をこの水平な踏面上にのせることができ、作業者は垂直な姿勢でタラップ1を歩行できる。
【0019】
手摺5は複数の縦支柱5aと縦支柱5a間に架設された横パイプ支柱5bとからなり、縦支柱5aの下端は側桁12の側面に設けた回転自在なソケット37に挿入されている。更に縦支柱5aの下部にはリンク38の上端がピン又はクランプ39を介して回転自在に結合され、このリンク38の他端は側桁12に設けた複数のピン孔40のいずれに枢着されている。この為、タラップ1の角度が変化した場合にはリンク38をいずれかのピン孔40に結合し、タラップ1の角度に対応して手摺5の角度を調整し、常に手摺5の角度がタラップ1に平行となるようにしている。タラップ1の下方上下にはジャッキ24が設けられ、このジャッキ24の高さを調整することによりタラップ1全体の角度を屋根面Aの勾配に合せて調整できるようにしている。
【0020】
ジャッキ24は図5に示すように、側桁12の側面にピン41を介して結合したナット26と、ナット26に上下移動自在に螺合したねじ桿27とで構成され、ねじ桿27の下端にはすべり止め又はクッション部材27a、ピンで止める止め板27b又は断面コ字状のつかみ金具27cを設け、タラップ1の角度をジャッキ24で調整すると共にこれらのジャッキ24を介してタラップ1を屋根面Aに保持されている。
【0021】
ねじ桿27はレバーLを上部に嵌合し、ハンドルを介してレバーLを回動することによりねじ桿27を回転して高さ調整を行なうものである。尚、タラップ1は安全の為、下端を枠組足場Cに結合しても良く、屋根の上方に図21、図22に示すトップ受具42を介して固定しても良い。
【0022】
トップ受具42は屋根面Aの棟部に保持され、これは一対の傾斜するソケット部43,43と、ソケット部43の上部に設けたヒンジ44と、各ソケット部43間に設けた角度調整リンク45と、各ソケット部43の下方に設けたクッション材からなる支持台46とからなり、屋根面上に配置したタラップ1における各側桁12の上端をそれぞれソケット部43に差し込み両者をピン孔47から挿入したピンで結合している。これによりトップ受具42が屋根の棟部に保持されていることからタラップ1が下方に落下しないようになっている。屋根の形状によってその勾配が異なる場合は角度調整リンク45の角度を拡げたり、縮めたりすることによって対応する。尚、例えば右側の一方のソケット部43は中間の連結材48を介して結合している。
【0023】
次にタラップ1の任意の位置、例えば、下方側部に足場板支持金具7が設けられ、この支持金具7を介してタラップ1の側部に水平方向に向けて足場板10を着脱自在に結合させるようになっている。
【0024】
足場板支持金具7は図5に示すように、水平な支持桿16と、支持桿16の中間に下方に向けて設けた支持片17と、支持片17に形成した複数の取付孔18とからなっている。支持桿16の一端は断面コ字状のブラケット49を介して側桁12の側面に枢着し、支持片17は任意の取付孔18を介して同様の側桁12の側面に固定されている。
【0025】
支持桿16の他端には手摺11を差し込むソケット50が結合されている。
【0026】
支持桿16には、例えば図10、図15又は図20に示す足場板10の端部フック51又は52を引掛けて足場板10を設置するものである。この場合、タラップ1の角度が変化しても、足場板10は常に水平に配置する必要がある。そこで、タラップ1の角度が変化した時は支持片17の取付け位置を取付孔18のいずれかを選択して常に支持桿16が水平になるように設定して対応させている。手摺5は通常タラップ1に沿って全域に設けられているが、足場板10に対応する部分は作業者がタラップ1から足場板10側に歩行できるように、支持金具7の近辺には手摺5を設けていない。この場合、手摺5における横パイプ支柱5bを図4、図6に示すようにスライド自在又は伸縮自在又は開閉自在に構成して、必要に応じて足場板10に連なる入口を開閉するようにしている。
【0027】
足場板10は例えば図10に示すように、本体10aと、本体10aの側面に起立するつま先板53と、本体10aの端部に設けたフック52とで構成し、フック52を支持桿16に引掛けるものである。
【0028】
図10、図11は、本発明の他の実施の形態に係る屋根工事用作業足場Eを示す。この場合、足場板支持金具8を図示のように構成したものでその他の設置方法、構造は上記図1乃至図9の実施の形態と同じである。
【0029】
この足場板支持金具8は菊座型の板クラッチ19と、板クラッチ19の端部に結合した水平な支持桿20とで構成され、支持桿20の両端には手摺5,10を差し込むソケット54,55が設けられている。板クラッチ19は側桁12側に板材56を介して結合した第1の円板57と、支持桿20側に結合した第2の円板58と、両者を貫通する締結ボルト59とで構成されている。
【0030】
第1、第2の円板57,58は歯車状でその表面に弯曲した多数の凹凸を放射方向に形成し、二つの円板57,58を密接した時両者が結合し、タラップ1の角度が変化した時、一方の、例えば第2の円板58を強制的に回転すると支持桿20が回転し、常に支持桿20を水平に保持するものである。
【0031】
図12乃至図19は本発明の他の実施の形態を示す。
【0032】
これは基本構造と設置方法は、上記の各実施の形態と同じであるが、タラップや支持金具等の構造を変形したものである。タラップ1は一対の側桁12と、各側桁12上に角度調整自在に結合した複数の足場板支持金具9と、各足場板支持金具9に着脱自在に結合したステップ13とで構成されている。
【0033】
タラップ1を構成する側桁12の下端は図17に示すように、枠組足場Cの縦材60に角度調整自在なユニバーサルジョイントGとヒンジHを介して結合され、タラップ1の角度はヒンジHを介して調整される。
【0034】
図17に示すように、側桁12の下部には高さ調整自在なややコ字状の軒先ガード61が垂設され、枠組足場Cと屋根との間に隙間Sがある場合、屋根面Aから落下した工具等が落下した時この落下物を軒先ガード61で収容できるようにしている。
【0035】
この軒先ガード61は図12、図16に示すように、タランプ62を介して枠組足場Cの縦材60に直接結合しても良い。
【0036】
この場合、軒先ガード61はややコ字状のフレーム63と、フレーム63上には展設したシートRで構成し、このシートRで落下した工具等を収容するようにしている。
【0037】
足場板支持金具9は側桁12上に起立する支持パイプ64と、支持パイプ64に嵌合した回転自在な断面逆U字状の支持枠65とで構成し、支持パイプ64には上下にピン孔を設け、支持枠65には上方のピン孔と下方の複数の調整孔66とを有している。
【0038】
上方のピン孔に挿入したボルト67は支持枠65を支持パイプ64に対して枢着し、下方のピン孔と調整孔66に挿入したボルト67は支持枠65の角度を調整するものである。
【0039】
即ち、タラップ1の角度を屋根面Aの勾配に合せて変化させた時、下方のボルト67を調整孔66のいずれか一つに差し込むことにより支持枠65を回転して常に垂直に起立させ、この垂直な支持枠65を介してタラップ側のステップ13と水平方向の足場板10を水平に保持するようにしている。
【0040】
この場合、支持枠65上には両側に一対の引掛片21,22を設けた足場板受け部材68を嵌合させ、これによりブラケット14上に引掛片21,22を起立させている。
【0041】
更に、図13、図15に示すように、受け部材68上には断面コ字状の保持金具69を嵌合させ、この保持金具69の両側にはスプリング70で附勢された一対のピン71、72を出没自在に設けている。
【0042】
図15に示すように、一方の引掛片22にはタラップ側のステップ13たる足場板本体10aのフック51を引掛け、他方の引掛片21には水平方向に延びる足場板10を引掛けるものである。この場合、例えばステップ13としての足場板本体10aを装着する場合にはピン71又は72に設けたハンドル73をスプリング70に抗して引張ってピン71をX方向に引き寄せておく。この状態で足場板本体10aのフック51を引掛片22に引掛け、次いでハンドル73の引張力を中止するとピン71がスプリング70で押し出されて足場板本体10a側のピン孔74に挿入されてステップ13を固定する。足場板10を固定する場合も同様である。尚、ステップ13は一方のピン72で先に保持し、このピン72を利用して回転させながら上記の取付け又は取はずし作業を行なっても良い。
【0043】
更に、図12に示すように、タラップ1上には手摺6が起立し、この手摺6はブラケット14に連設した取付具74を利用して結合するものである。
【0044】
更に、図12に示すように、タラップ1の下方には高さ調整自在なジャッキ25が設けられ、このジャッキ25を介してタラップ1が屋根面A上に配置される。
【0045】
このジャッキ25は図18、図19に示すように、上部の断面コ字状の側桁受け部材28と、この受け部材28の下部にヒンジ75を介してヒンジ結合したねじ筒29と、ねじ筒29内に上下移動自在に螺合したねじ桿30と、ねじ桿30の下端に設けたクッション材等からなる支持台30aとを備え、更に受け部材28とねじ筒29との間にはピン結合したリンク76が設けられ、通常このリンク76を介してねじ筒29は受け部材28に結合して垂直に起立している。但し、タラップ1の下方の屋根面Aの作業を行なう時、このジャッキ25が邪魔になるときは、リンク76をブラケット77からはずし、図18に示すようにねじ筒29を点線で示す位置まで横方向に変化させるものである。
【0046】
図20は本発明の他の実施の形態を示し、上記の各実施の形態と同じく、 タラップ1と、タラップ1の片側又は両側に起立する手摺と、タラップの側部に設けた足場板支持金具と、タラップ1の側部に当該タラップ1と直交する方向に配置する足場板10と、足場板10の片側又は両側に起立する手摺とを備え、屋根面の勾配に合せて角度調整しながら当該屋根面上にタラップ1を縦方向に配設し、タラップ1の角度に合せて角度調整しながら足場板支持金具を水平に配置し、足場板支持金具に足場板10の端部を結合しながら当該足場板10を屋根面上に水平方向に向けて配設し、更にタラップ1と足場板1おにそれぞれ手摺を角度調整しながら垂直に起立させものである。
【0047】
そして、上記タラップ1を一対の側桁12と、上記側桁12間に隔設した複数のステップ13で平行四辺形に構成し、上記足場板支持金具を上記ステップ13に結合した水平な支持桿23と、当該支持桿23の両端に設けた手摺挿入用のソケットとで構成している。
【0048】
更に下方のステップ13に扇形の取付片78を設け、この取付片78に複数のピン孔79を形成し、上記任意のピン孔79を介してピンを側桁12に挿入し、選択されたピン孔79に対応して側桁12の角度を調整するものである。
【0049】
その他の構造,作用,効果は上記各実施の形態と同じである。
【0050】
【発明の効果】
各請求項の発明によれば、次の効果がある。
【0051】
(1)各請求項の発明によれば、屋根面上に縦方向のタラップと水平方向の足場板が敷設され、タラップと足場板にはそれぞれ手摺が起立しているので作業者が常に垂直又は安全な姿勢で歩行し、作業が行なえるので歩行中又は作業中に転倒したり、屋根面から地上に落下するのが防止される。
【0052】
(2)タラップは屋根勾配に合せて角度調整できるから屋根の勾配がどのようなものであっても対応でき、又、タラップには角度調整自在な足場板支持金具を介して足場板が接続されるのでタラップの角度が変化しても足場板は常に水平に配置できる。

BACKGROUND OF THE INVENTION
The present invention relates to a roofing work scaffold used for roof construction, repair, and inspection work in a building such as a general house and a method for installing the same.
[0002]
[Prior art]
When building and repairing roofs of buildings such as ordinary houses, this roof has a slope of an arbitrary angle, so it is difficult for workers to walk vertically and horizontally along the roof surface, and the working posture Become unstable. Therefore, workability is poor, and in the worst case, there is a risk that the worker may fall and fall to the ground.
