このような構成の緊結金具を用いることにより、軒桁や妻梁などの横架材に対する天井梁およびたる木の取り付けを容易に行なうことができ、屋根組時の作業効率を大幅に向上させることができる。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態について、図面に基づいて説明する。
先ず、図１〜図５に示す第１の実施の形態について説明すると、１は柱２の上端で受けられ柱２の上端に釘打ちなどにより固定される軒桁や妻梁などの横架材で、この横架材１に対し天井梁３やたる木４が緊結金具５を介して固定される。
【０００８】
緊結金具５について詳細に述べると、緊結金具５は金属板を折り曲げ成形して作られ、ほぼ三角形の側板部６と、この側板部６の一端側における下端に内側に直角に連設され下端が横架材１から離れる方向に傾斜する傾斜板部７と、この傾斜板部７の上端に連設された位置決め用の板部８と、前記側板部６の上端の長さ方向のほぼ半分の長さ範囲で側板部６の一端側に偏った状態で連設された板部９とからなり、前記板部８は傾斜板部７の傾斜角度に対し緩やかな角度で傾斜するように傾斜板部７の上端に折り曲げられて連設され、また前記板部９は側板部６に対し外側に直角に折れ曲げられて連設されている。
【０００９】
この緊結金具５は前記天井梁３の端部に天井梁３が横架材１に載せられる前に取り付けられる。具体的には、側板部６の一端側外面および板部９の下面に当接し板部９に対し釘10打ちされることにより天井梁３の両端にそれぞれ前記緊結金具５が取り付けられる。そのとき、天井梁３の端部は緊結金具５の前記板部９の端部９ａと位置合わせされる。そして、横架材１に天井梁３が載せられるとき、横架材１の天井梁３載置部に予め底面を傾斜させて形成してある位置決め用の凹部11に前記位置決め用の板部８が嵌入して天井梁３が位置決めされる。このとき、前記傾斜板部７が横架材１の上端角部に当たりながら天井梁３が吊り降ろされ、前記位置決め用の板部８が位置決め用の凹部11に嵌入して凹部11の底面に載り、天井梁３が横架材１に載った状態において横架材１に対する天井梁３の位置合わせが完了する。その状態で前記傾斜板部７を横架材１に釘10打ちにより固定する。
【００１０】
このように横架材１に固定された緊結金具５の側板部６の内面にたる木４を当てがうとともに、たる木４を前記板部８上に載せ、側板部６の他端側で側板部６とたる木４を釘10打ちにより固定する。なお、たる木４は前記緊結金具５の位置でたる木４に予め釘10打ちにより取り付けてあるほぼＵ字状の位置決め金具12の両側の側板部13の端面が緊結金具５の側板部６の一端側端面に当接することにより位置決めされるとともに、棟の位置で棟木に固定される。ところで、前記位置決め金具12は底板部14がたる木４に釘10打ちにより固定されている。
【００１１】
以上の要領で横架材１の上に緊結金具５を介して天井梁３およびたる木４が固定されるのであって、天井梁３およびたる木４は横架材１の長さ方向に適当間隔おきに設けられる。
【００１２】
次に、図６〜図９に示す第２の実施の形態について説明すると、前記第１の実施の形態における緊結金具５は、傾斜板部７は側板部６の一端側における下端に内側に直角に連設されており、また傾斜板部７の上端に位置決め用の板部８が連設されているが、第２の実施の形態における緊結金具15では、側板部６の前後方向中間部下端に外側に直角に傾斜板部16を連設しており、また側板部６の前後方向一端側における下端に内側に直角に位置決め用の板部17を連設している点で、第１の実施の形態と第２の実施の形態では構成が多少異なるが、機能的には緊結金具５と緊結金具15と同じであるので、その詳細説明は省略する。また、図６〜図９において、前記第１の実施の形態と同一符号は同一部材を示している。
【００１３】
ところで、本発明は以上述べた２つの実施の形態以外に、例えば図１二点鎖線で示すように互いに平行な側板部６，６を一体に備えた緊結金具とすることもでき、その場合、互いに平行な側板部６，６の外側に２本の天井梁３の端部が当接して釘打ちされる。図６に示す緊結金具15についても同様に互いに平行な側板部６を一体に備えた構成とすることができる。
【００１４】
なお、以上述べた２つの実施の形態では、たる木４に位置決め金具12を取り付け、この位置決め金具12の両側の側板部13の端面を緊結金具５，15の側板部６の一端側端面に当接することによりたる木４の位置決めを行なうようになっているが、棟の位置で棟木に対するたる木４の位置合わせが正確になされておれば、位置決め金具12を用いずに緊結金具５の側板部６の内面にたる木４を当てがい、側板部６とたる木４を釘10打ちにより固定すれば良い。
【００１５】
【発明の効果】
以上のように本発明によれば、軒桁や妻梁などの横架材に対する天井梁およびたる木の取り付けを天井梁の端部に取り付けられる緊結金具により容易に行なうことができ、屋根組時の作業効率を大幅に向上させることができる。
