Description

【０００１】
【発明の属する技術分野】
本発明は、横架材の接合構造に関し、詳しくは、他の構造金物との干渉を回避でき、横架材受金具を用いて、第１横架材の側面部に第２横架材を側方から直角に固定することのできる横架材の接合構造に関する。
【０００２】
【従来の技術と発明が解決しようとする課題】
従来、木造建築物における梁等の横架材の端部を受け、該横架材を他の横架材の側面部に直角に接合する金物として、図７に示すような梁受け金物１０が知られている。このような金物を第１横架材２０と第２横架材３０との接合部に使用することにより、必要な接合強度を確保することができる。
【０００３】
しかし、第２の横架材３０が当接固定される第１の横架材２０の下には、図７に示すように、柱等の垂直材４０が設けられる場合が多く、該垂直材４０と上記第２の横架材３０との入隅部に筋交い固定用の金物（図示せず）を固定する場合や、該垂直材４０と上記第２の横架材２０とをホールダウン金物等引き寄せ金具（図示せず）で緊結する場合等には、金物同士が干渉し合うため、図７に示すような従来の梁受け金物１０を使用することができなかった。そのため、例えば入隅部に筋交い固定金物を固定する場合、梁受け金物に代えて羽子板ボルトを用いること等により対処せざるを得ず、作業が複雑化する等の問題を有していた。
【０００４】
また、例えば仮架構の段階において、梁受け金物で梁等の横架材を仮支持させれることができれば、作業手順の効率化を図ることができ、作業効率及び安全性を向上させることができるのであるが、上述のように梁受け金物を用いることができない場合があるため、作業効率及び安全性をより一層向上させることができなかった。
【０００５】
従って、本発明の目的は、接合部に他の構造金物等が配設される場合においても、該他の構造金物との干渉を回避することができ、横架材受金具を用いて、第１横架材の側面部に第２横架材を側方から直角に固定することのできる横架材の接合構造を提供することにある。
【０００６】
【課題を解決するための手段】
請求項１に記載の発明は、横架材受金具を用いて第１横架材の側面部に直角に第２横架材を固定してなる、横架材の接合構造において、上記横架材受金具は、第１横架材の側面部に面接固定された固定板部と、第２横架材の接合端部が載置された受け板部と、該固定板部と該受け板部とを連結し且つ該第２横架材の両側面部にそれぞれ面接固定された一対の連結板部とを備え、該固定板部、該受け板部及び一対の該連結板部は、それぞれ互いに断面Ｌ字状に結合されており、上記受け板部の上記第１横架材寄りの一側縁と該第１横架材との間に隙間が形成され、上記受け板部に載置された第２横架材の切断端部の下面が該隙間を介して下方に向かって露出しており、上記隙間を介して露出する上記第２横架材の下面に、筋交い固定金物が当接固定されており、上記筋交い固定金物は、上記第１横架材の下に配された垂直材にも当接固定されていることを特徴とする、横架材の接合構造を提供することにより、上記目的を達成したものである（以下、第１発明というときは、この発明をいう）。

【００１３】
【発明の実施の形態】
以下、第１発明の横架材の接合構造の一実施形態（以下、第１実施形態ともいう）及び第２発明の横架材の接合構造の一実施形態（以下、第２実施形態ともいう）について図１〜４を参照して説明する。
ここで、図１は本発明の第１及び第２実施形態の横架材の接合構造に用いた横架材受金具を示す図で、図１（ａ）は右側面図、図１（ｂ）は正面図である。図２は第１発明の横架材の接合構造の一実施形態（第１実施形態）を示す図であり、図３は第２発明の横架材の接合構造の一実施形態（第２実施形態）を示す図である。図４は図１の横架材受金具を形成するための金属片の板取りを示す図である。
以下、第１及び第２実施形態に用いた図 1 に示す横架材受金具を、第１実施形態の横架材受金具ともいう。
【００１４】
第１実施形態の横架材受金具は、図１〜図４に示されるように、第１横架材１の側面部１ａに面接固定される固定板部３と、該第１横架材１に直角に当接固定される第２横架材２の接合端部２ａが載置される受け板部４と、該固定板部３と該受け板部４とを連結し且つ該第２横架材２の両側面部２ｂ，２ｂにそれぞれ面接固定される一対の連結板部５，５とを備え、該固定板部３、該受け板部４及び一対の該連結板部５，５が、それぞれ互いに断面Ｌ字状に結合されている横架材受金具であって、上記固定板部３を上記第１横架材１に面接固定した際、上記受け板部４の該第１横架材１寄りの一側縁４ａと該第１横架材１との間に所定の隙間Ｓが形成されるようになされている。
【００１５】
第１実施形態の横架材受金具は、図１（ｂ）に示すように、上記固定板部３を左右に一対備えており、一対の該固定板部３，３は、図２に示すように上記第１横架材１と上記第２横架材２との当接部Ｃの両側にそれぞれ面接固定されるように設けられている。尚、本発明の横架材受金具の形成材料としては、梁受け金物やその他の構造金物の材料として通常公知の各種材料を特に制限なく用いることができる。
【００１６】
上記一対の固定板部３，３それぞれには、図１に示すように、該固定板部３を上記第１横架材１の側面部１ａに面接固定するための、ボルト孔３１及び釘孔３２が穿設されており、図２に示すように、両固定板部３，３をそれぞれ上記第１横架材１の側面部１ａに面接し、該ボルト孔３１及び該ボルト孔３１に対応させて第１横架材１に穿設された貫通孔（図示せず）を介してボルト３３及びナット（図示せず）で緊結し、更に上記釘孔３２に釘を打つことにより、該固定板部３を第１横架材１の側面部１ａに面接固定することができるようになっている。
【００１７】
上記一対の連結板部５，５それぞれは、図１に示すように、長手方向中央の中心線Ｌに対して左右対称の略台形状の形態を有し、該連結板部５の下縁５ａは、上記固定板部３に対して略４５度に傾斜する直線状となしてある。
【００１８】
また、上記連結板部５，５それぞれには、図１（ａ）に示すように該連結板部５を上記第２横架材２の側面部２ｂに面接固定するためのボルト孔５１及び釘孔５２が穿設されており、該ボルト孔５１及び該ボルト孔５１に対応させて第２横架材１に穿設した貫通孔（図示せず）を介して両側からボルト５３及びナット（図示せず）で緊締し、更に上記釘孔５２に釘を打つことにより、該連結板部５，５を該第２横架材の両側面部２ｂ，２ｂに面接固定することができるようになっている。
【００１９】
上記受け板部４は、直線状の両側縁を有する略矩形状の板状であり、上記固定板部３，３を第１横架材１の側面部１ａに面接固定した際、該第１横架材１寄りの一側縁４ａと該第１横架材１の側面部１ａとの間には、所定の隙間Ｓが形成されるようになっている。上記固定板部３，３を上記側面部１ａに面接固定した際、上記受け板部４の第１横架材１寄りの一側縁４ａと該第１横架材１の側面部１ａとの間に形成される隙間Ｓは、その幅Ｗ（図１参照）が３０ｍｍ〜１５０ｍｍであることが好ましく、３０ｍｍ〜９０ｍｍであることがより好ましい。上記隙間Ｓの幅Ｗが３０ｍｍ未満であると、該第２横架材２の接合端部に他の構造金物を固定等し難くなり、該幅Ｗが１５０ｍｍ超であると、金具に必要な強度を確保するために、より厚い金属板を用いて本金具を製造しなければならなくなる等の不都合がある。
【００２０】
このように第１実施形態の横架材受金具は、上記固定板部３を上記第１横架材１に面接固定した際、上記受け板部４と第１横架材１との間に所定の隙間Ｓが形成されるようになっているため、上記受け板部４に載置した第２横架材２の端部（接合端部）の下面が、該第２横架材２の第１横架材１との接合部近傍において露出した状態となる。
従って、図２に示す第１実施形態の横架材の接合構造におけるように、第２横架材２の下面の露出部に、筋交いを固定するための筋交い固定金物７を当接固定することが可能であり、また、図３に示す第２実施形態の横架材の接合構造におけるように、第２横架材２の下面から上面に至る貫通孔（図示せず）を穿設し、該貫通孔を貫通させてホールダウン金物８を配設することも可能である。
【００２１】
第１及び第２実施形態に用いた横架材受金具（第１実施形態の横架材受金具）は、鋼製金属板から切り出した一枚の金属片１１を、所定の４箇所において断面Ｌ字形状となるように直角に折曲して形成してある。
上記金属片１１は、図４に示すように、該金属片１１の中央部に配され、上記受け板部４を形成する矩形状の受け板部形成部１４と、該受け板部形成部１４の左右に連設され、上記連結板部５を形成する一対の連結板部形成部１５と、一対の該連結板部形成部１５それぞれの端部に連設され、上記固定板部３を形成する一対の固定板部形成部１３とからなり、上記連結板部形成部１５の両側縁１５ａ，１５ａ同士及び上記固定板部形成部１３の両側縁同士１３ａ，１３ａは、それぞれ互いに平行に形成されており、該金属片１１の左右の形状は、上記中央部を通る中心線Ｐに対して線対称となっている。本形態の横架材受金具は、このような金属片１１を、上記各形成部同士の境界部を折曲部として折り曲げて形成されている。
【００２２】
第１実施形態の横架材受金具は、このような形態の金属片１１を折曲して形成してあるため、該金属片１１を図４に示すように板取りすることにより効率的に歩留まり良く生産可能である。尚、図４においては、横架材受金具形成用の金属片１１を切り出すための切断線を実線で示し、横架材受金具を形成するための折曲部を点線で示してある。
【００２３】
また、第１実施形態の横架材受金具によれば、一対の上記連結板部５の下縁５ａを上記固定板部３に対して傾斜させてあるため、図３に示すように、該連結板部５の下に第２横架材２の側面が三角形状に露出する。そのため、他の構造金物や建物部材との干渉をより効果的に回避することができる。
【００２４】
次に、本発明に用い得る横架材受金具の他の例（以下、第２実施形態の横架材受金具ともいう）について図５及び図６を参照して説明する。ここで、図５は第２実施形態の横架材受金具を示す斜視図である。図６は、図５の横架材受金具の一使用状態を示す図である。
【００２５】
第２実施形態の横架材受金具（図５に示す横架材受金具）は、第１横架材１の側面部１ａに面接固定される一対の固定板部３，３と、該第１横架材１に直角に固定される第２横架材２の接合端部２ａが載置される受け板部４と、該固定板部３と該受け板部４とを連結し且つ該第２横架材２の両側面部２ｂ，２ｂに面接固定される一対の連結板部５，５とを備え、該固定板部３、該受け板部４及び該連結板部５が、それぞれ互いに断面Ｌ字状に結合されている点、上記固定板部３を上記第１横架材１に面接固定した際、上記受け板部４の該第１横架材１寄りの一側縁４ａと該第１横架材１との間に所定の隙間Ｓが形成されるようになされている点、上記固定板部３及び連結板部４にそれぞれボルト孔等及び釘孔が穿設されている点、一枚の金属板を折曲して形成されている点等において上記第１実施形態の横架材受金具（図１に示す横架材受金具）と同様である。
【００２６】
第２実施形態の横架材受金具においては、一対の該固定板部３，３が互いに対向して設けられ、上記第２横架材が一対の該固定板部３，３に当接されて上記第１横架材に固定されるようになされている。即ち、本金具形成用の、一枚の金属片における、上記受け板部４の形成部と上記連結板部５の形成部との境界部における折り曲げ方向を谷折りとすれば、該連結板部５の形成部と上記固定板部３の形成部との境界部も同様に谷折りとして形成してある。
【００２７】
上記一対の固定板部３，３の端部同士は互いに接合されており、両固定板部３，３は一枚の板状の形態をなしている。このように、固定板部３，３の端部同士を互いに溶接等で接合することにより、荷重に対する強度を向上させることができ、歪みの発生等を効果的に防止することができる。尚、固定板部３，３の端部同士を接合せずに、一対の固定板部３，３が隙間を介して対向するようにしても良い。
【００２８】
また、一対の上記連結板部５，５それぞれの上方には、上記固定板部３及び上記連結板部５に連設され且つ該連結板部５と同一面上にある補強板部６が延設されている。上記補強板部６は、上記固定板部３と上記連結板部５との連結部において該固定板部５に沿う所定幅の板状体として設けられており、該補強板部６がリブとして機能することにより上記固定板部３の反りが抑制されるようになっている。
【００２９】
上記固定板部３の下端３ｂは該固定板部３と上記連結板部５との連結部よりも下方に位置しており、図６に示すように、本形態の横架材受金具を、床梁ないし大引き２を基礎９上の土台１に直角に固定する接合部に用いた場合に、該固定板部３の下端３ｂが基礎９上に当接するようになっている。これにより、横架材受金具の下方への移動が完全に阻止され、床梁ないし大引き２と土台１との接合状態が長期間安定に維持される。このように横架材受金具を、他の建物部材（基礎）９上に載置された第１の横架材（土台）１に第２の横架材２を接合するために用いる場合、上記固定板部３の下端３ｂが該建物部材９の上面に当接するようにすることが好ましい。これにより強固な接合状態を長期間安定的に維持することができる。
【００３０】
図５に示す第２実施形態の横架材受金具によれば、図１に示す第１実施形態の横架材受金具と同様に、上記固定板部３を上記第１横架材１に面接固定した際、上記受け板部４の該第１横架材１寄りの一側縁４ａと該第１横架材１との間に所定の隙間Ｓが形成されるようになされているため、第１横架材１と第２横架材２との接合部に、筋交い固定金物やホールダウン金物等の他の構造金物が配設される場合においても該他の構造金物との干渉を回避することができ、第１横架材１の側面部１ａに直角に且つ強固に第２横架材２を固定することができる。尚、本第２実施形態の横架材受金具における隙間Ｓの幅の好ましい範囲も図１に示す第１実施形態の横架材受金具におけるのと同様である。
【００３１】
また、第２実施形態の横架材受金具によれば、一対の該固定板部３，３が互いに対向して設けられ、上記第２横架材が一対の該固定板部３，３に当接されて上記第１横架材に固定されるようになされているため、第１横架材１の端部における側面部に第２横架材２を接合させる場合や、柱等の垂直材に第２横架材２を接合させる場合等、第２横架材２の当接部の片側あるいは両側に固定板部を固定する面が存在しない場合においても、本横架材受金具を固定することができ、第２横架材を第１横架材に接合することができる。即ち、第２実施形態の横架材受金具によれば、被接合材が横架材であると柱等の垂直材であるとを問わず、他の構造金物や建物部材等との干渉を回避して横架材を直角且つ強固に固定することができる。
【００３２】
また、第２実施形態の横架材受金具によれば、上記補強板部６がリブとして機能し、上記固定板部３の反りが抑制されるので、優れた接合強度が得られると共に、優れた強度が長期間維持される。
【００３３】
以上、本発明の横架材の接合構造のいくつかの実施形態について説明したが、本発明の横架材の接合構造は、これらの実施形態に制限されず本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００３４】
例えば、第１実施形態の横架材受金具に、図２に一点鎖線で示したように、上記第２実施形態の横架材受金具におけるのと同様な補強板部６を設けることが好ましい。これにより、固定板部３，３の反りが防止され、優れた接合強度がより長期間維持されるようになる。尚、このように補強板部６を設ける場合、図４に示す金属板における、一の金属片１１の固定板部形成部１３と、隣接する他の金属片１１の固定板部形成部１３との間の領域１６（図４における斜線部分）を該補強板部６の形成部として用いれば、材料に無駄を生じることなく効率的に横架材受具の生産が可能である。
【００３５】
また、第１実施形態の横架材受金具における上記固定板部３の下方に延びる突出部分（図５の点線Ｒより下の部分）を無くしても良い。
また、本発明に用いる横架材受金具は、上記両横架材受金具におけるように一枚の金属片を折曲して形成することが好ましいが、複数の金属片を溶接接合し又は機械的に接合して形成しても良い。
【００３６】
尚、本発明における第１横架材及び第２横架材は、木造住宅においてほぼ水平方向に配される部材であれば、梁、桁、胴差、土台、大引き等特に制限されず、また、本発明の横架材受金具は、柱、間柱等の垂直材にこのような横架材を接合させるために用い得るものであっても良い。
【００３７】
また、上記両横架材受金具における上記受け板部４の上記第１横架材１寄りの一側縁４ａは、該第１横架材１に平行な直線状としてあるが、筋交い固定金物やホールダウン金物等の他の構造金物等との関係において更に効果的に構造金物同士の干渉を防止するために、該側縁４ａの一部を切り欠いたり、該側縁４ａを円弧状に又は多段状に形成する等しても良い。また、上記連結板部５の下縁５ａの形状についても、直線状の他、円弧状等の曲線状、中間に単一又は複数の段部を有する形状等としても良い。また、上記固定板部及び上記連結板部を上記横架材１，２に面接固定するには、上記ボルトや釘等の他、ネジや、より強度が高まるラグスクリューボルト等を用いても良い。更に、その他の部分の形状、寸法等についても、本発明の趣旨を逸脱しない範囲内において適宜変更可能である。
【００３８】
【発明の効果】
以上の説明から明らかなように、本発明の横架材の接合構造によれば、接合部に他の構造金物等が固定ないし配設される場合においても、該他の構造金物等との干渉を回避することができ、横架材受金具を用いて、第１横架材の側面部に強固に第２横架材を固定することができる。
