Description

【０００１】
【発明の属する技術分野】
本発明は、建築物の内装工事において、壁を形成する際の金属製下地材として使用される金属製角筒柱に関するものである。
【０００２】
【従来の技術】
この種の金属製角筒柱として、建築物の内装工事に使用される金属製壁下地材として一般的に普及しているものは、壁下地材として、上部ランナーと呼ばれる天井面側の下向きコ字状の金属製上横桟（金属製チャンネル材）と下部ランナーと呼ばれる床面側の上向きコ字状の金属製下横桟（金属製チャンネル材）との間にスタッドと呼ばれる金属製角筒柱を横桟長手方向に適当間隔に立設し、この金属製角筒柱の室内外面に上貼り壁用のボード材をビス等で固着している。
【０００３】
そして、各角筒柱の中間部に左右に貫通する開口部を設け、この両開口部に断面コ字状の振れ止め用横桟を挿通して取り付け、各横桟を介して各角筒柱が互いに規制し合って室前後方向に振れるのを阻止し、これによって壁面の堅牢性を図るようにしている。
【０００４】
そして、この金属製角筒柱の最近の従来技術として、前記開口部の前後両側縁部に観音扉状に折曲可能な抜止片を突設して、前記開口部に挿通させた振れ止め用横桟の前後両側面が前記抜止片に押圧されて振れ止め用横桟が両開口部から抜け出るのを阻止するようにした技術が本件出願人から提案されている。（例えば、特許文献１）。

【発明が解決しようとする課題】
上記のような従来の壁下地用金属製角筒柱にあっては、その開口部に設けた観音扉状の抜止片の構成が複雑なため、これが障害となって振れ止め用横桟を左右の両開口部に挿通させることがかなり面倒であった。
【０００７】
本発明は、振れ止め用横桟を挿通させるための左右両開口部の構成を簡単にして、振れ止め用横桟を両開口部にわたって容易に挿通させることができる共に、その支持力、即ち抜け止め作用（ガタツキ防止作用）を良好に達成することができる壁下地用金属製角筒柱を提案することを目的とするものである。
【０００８】
【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に係る発明は、参照符号を付して示せば、鉛直に立設される金属製角筒柱状本体１ａの中空部１ｏを挟んで相対向する二面には、ウェブ部２ａとその両端のフランジ部２ｂ，２ｂとからなるコ字状の振れ止め用横桟２を横向きコ字状の姿勢で左右方向に挿通させる開口部３，４が設けられ、この左右の両開口部３，４は、振れ止め用横桟２の上面部（上側のフランジ部２ｂ）に対向する上縁部３ａ，４ａと振れ止め用横桟２の下面部（下側のフランジ部２ｂ）に対向する下縁部３ｂ，４ｂと、振れ止め用横桟２の前側面部（ウェブ部２ａ又はフランジ部端縁２ｃ）に対向する前側縁部３ｃ，４ｃと、同じく後側面部（フランジ部端縁２ｃ又はウェブ部２ａ）に対向する後側縁部３ｄ，４ｄとからなり、このうち、上記左右の両開口部３，４の夫々の上縁部３ａ，４ａと下縁部３ｂ，４ｂとは、前記角筒柱状本体１ａの鉛直方向に同一高さで、該鉛直方向に対して垂直な線上にあり、上記左右の両開口部３，４の前後側縁部３ｃ，４ｃ，３ｄ，４ｄのうち、何れか一方の開口部３の前後側縁部３ｃ，３ｄは、角筒柱状本体１の鉛直線ｐ上に対してプラスθ角度傾斜した傾斜線ｑ上にあり、他方の開口部４の前後側縁部４ｃ，４ｄは角筒柱状本体１ａの鉛直線ｐ上に対してマイナスθ角度傾斜した傾斜線ｒ上にあり、これによって両開口部３，４がその開口部中心３ｏ，４ｏを交点として略Ｘ字状に対向配置されてなる構成からなるものである。
【０００９】
また請求項２に係る発明にあっては、前記両開口部３，４の前後両側縁部３ｃ，３ｄ，４ｃ，４ｄに、前記振れ止め用横桟２の前後側面部２ａ，２ｃが当接する当接片５ａ，５ｂ，６ａ，６ｂが突設されてなる請求項１に記載の構成からなるものである。
【００１０】
【発明の実施の形態】
図１は、本発明に係る金属製角筒柱１を使用して形成される壁下地材を示したもので、従来の壁下地材と同様に、上部ランナーと呼ばれる天井面側の金属製上横桟７と下部ランナーと呼ばれる床面側の金属製下横桟８との間に、スタッドと呼ばれる金属製角筒柱１を横桟長手方向に適当間隔おきに立設し、この金属製角筒柱１の室内外両面に上貼り壁用のボード材９を固着し、そして各角筒柱１には振れ止め用横桟２を横向きコ字状の姿勢で角筒柱１を貫通するように取り付け、これによって壁面の堅牢性を図っている。
【００１１】
この実施形態において、金属製角筒柱１は、横桟２，７，８と直交する水平方向の幅寸法ａが例えば２５ｍｍ、横桟２，７，８の長手方向に沿った水平方向の幅寸法ｂが４０ｍｍである。
【００１２】
図２は、金属製角筒柱状本体１ａの要部を示す斜視図であり、図３は、該角筒柱状本体１ａの左側面図である。図４は、該角筒柱状本体１ａの右側面頭である。図５は、図３のＡーＡ線断面図である。図６は、図３のＢーＢ線断面図である。これらの図において、上記金属製角筒柱１の角筒柱状本体１ａは、図２に示すように、金属板を角筒状に折曲してその対向縁部をＪ字状やＵ字状に折曲し、これらの折曲部を互いに絡ませて接合する所謂はぜ接合構造１０によって、角筒柱１に形成されたものである。
【００１３】
この角筒柱状本体１ａの中空部１ｏを挟んで相対向する二面には、図２に示すようにウェブ部２ａとその両端のフランジ部２ｂ，２ｂとからなる横断面コ字状振れ止め用横桟２を横向きコ字状の姿勢で挿通させるための開口部３，４が設けられ、両開口部３，４は、振れ止め用横桟２の上面部（上側のフランジ部２ｂ）に対向する上縁部３ａ，４ａと振れ止め用横桟２の下面部（下側のフランジ部２ｂ）に対向する下縁部３ｂ，４ｂと、振れ止め用横桟２の前側面部（ウェブ部２ａ又はフランジ部端縁２ｃ）に対向する前側縁部３ｃ，４ｃと、同じく後側面部（フランジ部端縁２ｃ又はウェブ部２ａ）に対向する後側縁部３ｄ，４ｄとからなり、このうち、上記左右の両開口部３，４の夫々の上縁部３ａ，４ａと下縁部３ｂ，４ｂとは、前記角筒柱状本体１ａの鉛直方向に同一高さで、該鉛直方向に対して垂直な線上に平行状態にあり、上記左右の両開口部３，４の前後側縁部３ｃ，４ｃ，３ｄ，４ｄのうち、何れか一方の開口部３の前後側縁部３ｃ，３ｄは、角筒柱状本体１の鉛直線ｐ上に対してプラスθ角度傾斜した傾斜線ｑ上にあり（図２、図３参照）、他方の開口部４の前後側縁部４ｃ，４ｄは角筒柱状本体１ａの鉛直線ｐ上に対してマイナスθ角度傾斜した傾斜線ｒ上にあり（図２、図４）、これら開口部３の前側縁部３ｃと後側縁部３ｄとは同じプラスθ角度で、又、開口部４の前側縁部４ｃと後側縁部４ｄとは同じマイナスθ角度であるから、夫々平行状態にある。
【００１４】
即ち、一方の開口部３は、上下縁部３ａ，３ｂ間の前後両側縁部３ｃ，３ｄは、その上端部から下端部に向かって左右の何れか一方側に、例えば前側（図中左側）に傾斜して平行に形成され、全体として前（左）側傾斜の平行四辺形の開口部３に形成される。これに対して、他方側の開口部４は、上下縁部４ａ，４ｂ間の前後側縁部４ｃ，４ｄは、その上端部から下端部に向かって左右の何れか一方側に、例えば後側（図中右側）に傾斜して平行に形成され、全体として後（右）側傾斜の平行四辺形の開口部３に形成される。
【００１５】
これがために、図２〜図４に示すように、前側傾斜の平行四辺形の開口部３と後側傾斜の平行四辺形の開口部４とは、夫々の開口部中心３ｏ，４ｏを同心状に重ねた場合に、これらの開口部中心３ｏ，４ｏを交点として略Ｘ字状に対向配置された構成となっている。
【００１６】
なお、図２に示すように、上記振れ止め用横桟２はチャンネル材からなるもので、ウェブ部２ａの幅ａが３８ｍｍ、フランジ部２ｂの幅ｂが１２ｍｍとされ、また角筒柱１の開口部３，４は縦幅ｃが４５ｍｍ、横幅ｄが１５ｍｍとされる。
【００１７】
上記開口部３，４の形成にあたっては、金属板を角筒状に折曲する前の展開状態で開口部３，４の形成位置を切り抜いて、その後に、その展開状態の金属板を角筒状に折曲して金属製角筒柱１を形成すればよい。
【００１８】
本発明の一実施形態は、以上のような構成からなり、これを使用するには、図１に示すように、先ず天井面側に上部ランナーである上横桟７をビスの打ち込みによって取り付け、床面側に下部ランナーである下横桟８を同様にビスの打ち込みによって取り付け、上下両横桟７，８の間に、スタッドと呼ばれる本発明に係る金属製角筒柱１を適当間隔おきに鉛直に立設する。
【００１９】
しかる後、振れ止め用横桟２を、図２に示すように横向きコ字状の姿勢で角筒柱１の何れかの開口部３から角筒柱本体１ａ内に差し込んで、他方の開口部４から引き出し、しかして隣接する角筒柱１の開口部３，４に順次差し込み且つ引き出すようにして振れ止め用横桟２を複数の角筒柱１に貫通させる。
【００２０】
この際に、角筒柱状本体１ａに形成された開口部３，４は、図２〜図４に示すように、夫々の開口部３，４の前後側縁部３ｃ，４ｃ，３ｄ，４ｄのうち、何れか一方の開口部３の前後側縁部３ｃ，３ｄは、角筒柱状本体１の鉛直線ｐ上に対してプラスθ角度傾斜した傾斜線ｑ上にあり、他方の開口部４の前後側縁部４ｃ，４ｄは角筒柱状本体１ａの鉛直線ｐ上に対してマイナスθ角度傾斜した傾斜線ｒ上にあり、これによって両開口部３，４がその開口部中心３ｏ，４ｏを交点として略Ｘ字状に対向配置されてなる。
【００２１】
このため、振れ止め用横桟２を一方側の開口部３に差し込んだときには、図３〜図６に示すように、開口部３では、その前側縁部３ｃの上部に振れ止め用横桟２のウェブ部２ａの上部が当接し、後側縁部３ｄの下部に振れ止め用横桟２の下側のフランジ端縁２ｃが当接し、一方、振れ止め用横桟２を引き出す側の開口部４では、図４〜図６に示すように、その後側縁部４ｄの上部に振れ止め用横桟２の上側のフランジ端縁２ｃが当接し、前側縁部４ｃの下部にウェブ部２ａの下部が当接し、これによって、振れ止め用横桟２は、一方の開口部３では振れ止め用横桟２のウェブ部２ａの上部と、下側のフランジ端縁２ｃが開口部３の前後側縁部３ｃ，３ｄで当接規制され、他方の開口部４では、上記当接点とは点対称位置にある振れ止め用横桟２の上側のフランジ端縁２ｃと、ウェブ部２ａの下部が開口部４の前後側端縁部４ｃ，４ｄで当接規制され、この両開口部３，４による振れ止め用横桟２に対する前後互いにＸ状に交差する位置の４点支持構造によって、振れ止め用横桟２は両開口部３，４にガタツキなく保持されることになる。
【００２２】
特に、この実施形態にあっては、両開口部３，４は、四辺のうちの二辺である前後側縁部の傾斜角が一方がプラスθ角度であり、他方がマイナスθ角度になっているだけで、何れも同じ平行四辺形形状となっているに過ぎないから、振れ止め用横桟２を両開口部３，４に差し込む際に、何れかの開口部３または４からも差し込むことができ、またコ字状の振れ止め用横桟２のウェブ部２ａとフランジ部２ｂ，２ｂの向きを前後何れの方向に反転しても両開口部３，４に挿入することができ、これがために施工する現場の条件に合わせて自在に使用することができるというメリットがある。
【００２３】
しかも、角筒柱状本体１ａには、簡単な開口部形状も形成するだけであるから、安価に製作することができ、しかも開口部３，４の堅牢な周縁で振れ止め用横桟２を当接させるのであるから、振れ止め用横桟２を強固に角筒柱状本体１ａに支持させることができる。
【００２４】
図７〜図１２は、本発明の他の実施形態を示すのもで、前記実施形態と異なるところは、角筒柱状本体１ａに設けた両開口部３，４の前後両側縁部３ｃ，３ｄ，４ｃ，４ｄに、振れ止め用横桟２の前後側面部２ａ，２ｃが当接する当接片５ａ，５ｂ，６ａ，６ｂが突設されてなる点であり、その他の構造は前記実施形態と同じである。従って、前記実施形態と同一構成要素については同一符号を付して、その説明を省略するものとし、必要箇所のみ以下に説明する。
【００２５】
上記当接片５ａ，５ｂ，６ａ，６ｂの形成にあたっては、金属板を角筒状に折曲する前の展開状態で金属板の開口部３，４形成位置に所定の切り込みを入れて、開口部７内に当接片５ａ，５ｂ，６ａ，６ｂのみが残るように他の不要部分を抜き取った後、その展開状態の金属板を角筒状に折曲してはぜ接合構造１０によって金属製角筒柱１を形成する。これが図７に示すとおりである。
【００２６】
図８に示すように、当接片５ａ，５ｂ，６ａ，６ｂは、その突出量が４ｍｍ程度の短片からなり、振れ止め用横桟２を開口部３，４に挿入しない前は、開口部３側の当接片５ａ，５ｂは、中空部１ｏ内に略ハの字状に、また開口部４側の当接片６ａ，６ｂは、開口部４から外側に略ハの字状に夫々半開き状態に突設されている。
【００２７】
この状態で、振れ止め用横桟２を図７、図９〜図１１に示すように、角筒柱状本体１ａの両開口部３，４に挿入することによって、振れ止め用横桟２は、前記実施形態と同じように、一方の開口部３では振れ止め用横桟２のウェブ部２ａの上部と、下側のフランジ端縁２ｃが開口部３の前後側縁部３ｃ，３ｄで当接規制され、他方の開口部４では、上記当接点とは点対称位置にある振れ止め用横桟２の上側のフランジ端縁２ｃと、ウェブ部２ａの下部が開口部４の前後側端縁部４ｃ，４ｄで当接規制され、尚且つ、開口部３，４の前後側縁部３ｃ，３ｄ，４ｃ，４ｄの振れ止め用横桟２に対する当接箇所では、同時に当接片５ａ，５ｂ，６ａ，６ｂがその半開き状態から更に強制的に弾性変形して開放され、これらの当接片が振れ止め用横桟２に弾性面接触状に当接し、振れ止め用横桟２に対する前後互いにＸ状に交差する位置の当接片付きの両開口部３，４の４点支持構造によって、振れ止め用横桟２は前記実施形態に比べてより強力に両開口部３，４にガタツキなく保持されることになる。
【００２８】
【発明の効果】
請求項１に係る発明によれば、左右に鉛直状に適当間隔に立設した金属製角筒柱状本体にその中空部を挟んで左右の面に設けた左右の開口部に振れ止め用横桟を順次に挿入保持させる際に、振れ止め用横桟は、一方の開口部では振れ止め用横桟のウェブ部の上部と、下側のフランジ端縁が開口部の前後側縁部で当接規制され、他方の開口部では、上記当接点とは点対称位置にある振れ止め用横桟の上側のフランジ端縁と、ウェブ部の下部が開口部の前後側端縁部で当接規制され、この両開口部による振れ止め用横桟に対する前後互いにＸ状に交差する位置の４点支持構造によって、振れ止め用横桟は両開口部にガタツキなく保持されることになる。
【００２９】
更に本発明にあっては、角筒柱状本体の中空部を挟んで設けた左右の両開口部は、四辺のうちの二辺である前後側縁部の傾斜角が一方がプラスθ角度であり、他方がマイナスθ角度になっているだけで、何れも同じ平行四辺形形状となっているに過ぎないから、振れ止め用横桟を両開口部に差し込み引き出す際に、左右の何れの開口部からも差し込み引き出すことができ、更にはコ字状の振れ止め用横桟のウェブ部とフランジ部の向きを前後何れの方向に反転しても両開口部に挿入することができ、これがために施工する現場の条件に合わせて自在に使用することができるというメリットがある。
【００３０】
しかも、本発明にあっては、角筒柱状本体には、簡単な開口部形状も形成するだけであるから、安価に製作することができ、しかも開口部の堅牢な周縁で振れ止め用横桟を当接させるのであるから、振れ止め用横桟を強固に角筒柱状本体に支持させることができる。
【００３１】
また請求項２に係る発明にあっては、請求項１と同じように、左右に鉛直状に適当間隔に立設した金属製角筒柱状本体にその中空部を挟んで左右の面に設けた左右の開口部に振れ止め用横桟を順次に挿入保持させる際に、振れ止め用横桟は、一方の開口部では振れ止め用横桟のウェブ部の上部と、下側のフランジ端縁が開口部の前後側縁部で当接規制され、他方の開口部では、上記当接点とは点対称位置にある振れ止め用横桟の上側のフランジ端縁と、ウェブ部の下部が開口部の前後側端縁部で当接規制され、尚且つ、開口部の前後側縁部の振れ止め用横桟に対する当接箇所では、同時に当接片がその半開き状態から更に強制的に弾性変形して開放され、これらの当接片が振れ止め用横桟に弾性面接触状に当接し、振れ止め用横桟に対する前後互いにＸ状に交差する位置の当接片付きの両開口部の４点支持構造によって、振れ止め用横桟は前記実施形態に比べてより強力に両開口部にガタツキなく保持されることになる。
