Description

【０００１】
【発明の属する技術分野】
本発明は、屋根部を支える壁部または梁と屋根部との間に配置される接合部材に関する。
【０００２】
【関連技術および発明が解決しようとする課題】
従来、傾斜をもつ屋根部を支え、その傾斜方向と交差する壁部または梁の上部には木製の結合桁が用いられ、このような場合には、屋根部と壁部または梁とを結合させるために、別部材である緊結金物を用いる必要があった。また、梁の上部に設置される結合桁の場合には、この緊結金物は、結合桁を両側から押さえ、その上部の屋根部が上部から圧迫する状態になるように作用して、結合桁を梁上に固定する役割のためにも必要であった。
【０００３】
また、従来の結合桁は、木製であるため、乾燥等による形状の経時変化が生じることがあり、それを用いた構造全体に影響を及ぼすことがあった。
【０００４】
さらに、従来の結合桁は、木製であるため、様々な付属部材を十分な強度をもって結合桁に取り付けることは容易には行えなかった。
【０００５】
本発明は、上記のような問題点を解決するためになされたものであって、その目的とするところは、特別な部材を必要とすることなく、壁部または梁部に固定することができ、屋根部と壁部または梁とを結合させるために、別部材である緊結金物を必要としない結合桁の機能を有する屋根部と壁部または梁との接合部材を提供することにある。
【０００６】
また、本発明の他の目的は、乾燥等による形状の経時変化によって、それを用いた構造全体に影響を及ぼすことがない結合桁の機能を有する屋根部と壁部または梁との接合部材を提供することにある。
【０００７】
【０００８】
【０００９】
【課題を解決するための手段】
本発明に係る接合部材は、
屋根傾斜方向に沿って伸びる屋根芯材と壁部または梁とを結合させる結合桁と、
前記屋根芯材と前記結合桁とを緊結し、前記屋根芯材を含んで構成される屋根部の吹き上げを防止する吹き上げ防止部材と、
を有する金属製の接合部材であって、
前記結合桁は、
前記壁部または前記梁に載置される載置面を有する載置部と、
前記壁部または前記梁に取り付けられる第１取付部と、
前記屋根部の前記屋根芯材が載置される傾斜面を有する傾斜部と、
前記吹き上げ防止部材が係合される被係合部とを有し、
前記傾斜部は前記傾斜面に貼付され前記屋根部の前記屋根芯材との間の軋みや滑りを防止する滑り防止シートを有し、
前記第１の取付部は、前記載置面よりも下方にのびて壁部または梁の側面に取付け可能とされ、
前記吹き上げ防止部材は、
前記屋根芯材に前記壁部または梁の側面延長線よりも上端側を屋根傾斜方向斜め上方に向けて取り付けられる第２取付部と、
前記第２の取付部に対して軸回りで回転可能に取付けられ、前記結合桁の前記被係合部に係合される係合部と、
を有することを特徴とする。
【００１０】
ここで、前記屋根芯材は、壁部または梁と交差し、壁部または梁によって支持される屋根用芯材を意味し、例えば、パネル工法にあっては屋根パネルの一構成要素である縦方向の芯材であり、在来工法にあっては垂木である。また、前記梁は、屋根用芯材を受ける鋼製または木製の桁を意味し、パネル工法にあっては屋根梁であり、在来工法にあっては母屋桁、軒桁、および棟木である。
【００１１】
また、前記屋根部は、例えば、パネル工法においては、屋根芯材と面材とを含んで構成される屋根パネルを意味し、在来工法においては、垂木と屋根板を含んで構成される部分を意味する。
【００１２】
本発明に係る接合部材によれば、その結合桁の載置部を壁部または梁に載置し、第１取付部をその壁部または梁に取り付けることによって、壁部または梁に固定でき、そして、傾斜部に屋根傾斜方向に沿って伸びる屋根芯材を載置し、吹き上げ防止部材によって屋根部を結合桁に緊結することができる。したがって、この接合部材の壁部または梁への固定は、特別な部材を必要とすることなく、単に取り付け部を釘等によって壁部または梁に固定することによって行うことができる。また、この結合桁は金属製であるため、木製の結合桁の場合のように、乾燥等による形状の経時変化がなく、それを用いた構造全体に形状変化による影響を及ぼすこともない。さらに、本発明の結合桁は金属製であるため、吹き上げ防止部材を含む様々な付属部材を十分な強度をもって結合桁に容易に取り付けることができる。
【００１３】
【００１４】
【００１５】
【００１６】
【００１７】
【００１８】
また、前記結合桁は、前記傾斜部の傾斜面に貼付され前記屋根部の前記屋根芯材との間の軋みや滑りを防止する滑り防止シートを有する。
【００１９】
これによって、傾斜部には屋根芯材との間の軋みや滑りを防止する滑り防止シートが貼付される。したがって、屋根部の取付の際に屋根部が滑り落ちたりする可能性を減少させることができるとともに、屋根部取付後の屋根の軋み音等を減少させることができる。

【発明の実施の形態】
以下、本発明の好適な実施例について、図面を参照しながら詳細に説明する。図２は、本実施例の結合桁１０を用いた構造の一例を示す分解斜視図である。同図には、結合桁１０が、複数の壁パネル３２を含んで構成される壁部２６上に設置された例が示されている。結合桁１０の上部には、この図には壁部２６から離して描いてあるが、傾斜を持つ屋根部３４が位置して、屋根部３４の傾斜方向に伸びる屋根芯材３６が、結合桁１０上に載置された状態となる。なお、壁部２６は屋根部３４の傾斜方向と交差する位置関係にある。
【００２９】
図３および図４は、このような結合桁１０が一般的な家屋で使用される箇所を示す斜視図および平面図である。図３に示すように、結合桁１０は、傾斜を有する屋根部（図示せず）の傾斜方向と壁部２６または梁４６とが交差する場合に、壁部２６または梁４６の上部に用いられる。また、図４は、図３とは異なる家屋において、屋根部３４の屋根芯材３６を支持する構造の配置を、平面図として示している。この図に示す家屋周辺部においては、主として壁部２６が屋根部３４を支持し、それ以外の部分においては主として梁４６が屋根部３４を支持している。また、太い実線で示してある部分に、結合桁１０が配置される。なお、太い実線の間に白抜きの部分があるのは、屋根部３４を支持する壁部２６または梁４６と他の部材例えば梁４６、屋切りパネル７６との接合部材を兼ねる結合桁１０が使用される部分を示している。
【００３０】
図１は、図２で示した壁部２６上に設置された本実施例の結合桁１０の詳細を示す斜視図である。また、図５および図６は、図１で示した壁部２６および結合桁１０の上部に屋根部３４が設置された状態を示す断面図および正面図である。これらの図に示すように、結合桁１０は、その載置部１２の載置面８４が壁部２６等の上に位置するように設置され、その第１取付部である取付部１４を壁部等に釘等で固定することによって、壁部２６等の上部に取り付けられる。そして、結合桁の傾斜部１６の傾斜面９２上に、屋根部１０の芯材で屋根部の傾斜方向に伸びる屋根芯材３６が位置して屋根部３４が設置される。また、本実施例の結合桁１０は鋼などの十分な強度を持つ金属によって形成されている。
【００３１】
なお、この傾斜部１６の傾斜面９２上に、予め屋根部３４の屋根芯材３６と傾斜部１６の傾斜面９２との間の軋みや滑りを防止するシートである滑り防止シート（図示せず）を貼付しておいてもよい。これによって、屋根芯材３６の取付の際に屋根芯材３６が滑り落ちたりする可能性を減少させることができるとともに、屋根芯材３６の取付後の軋み音を減少させることができる。
【００３２】
また、例えば図７に示したように、載置部１２の一部に釘穴２２を設け、その上方の傾斜部１６にドライバー等を差し込むための穴２４を設けて、載置部１２を壁部２６や梁４６などの上面に直接固定するようにしてもよい。この場合は、載置部１２が取付部を兼ねるため、図１、図５、および図６等で示した取付部１４は不要となる。
【００３３】
また、本実施例の結合桁１０は、図１に斜視図として示したように、ストッパ部５４、固定部５６、吊り金具通過孔６６、などを含んで構成してもよい。
【００３４】
ストッパ部５４は、図１および図５に示すように、結合桁１０の側面部１８にビス２０等や溶接等によって一体的に固定され、その一部が傾斜部１６の上方に突出している。屋根部３４例えば屋根パネル４２を結合桁１０上に設置すると、この突出した部分が図２に示した屋根部３４の係合部材４０の屋根傾斜方向の下方の側面を支持し、それ以上下方に移動しないようにして、屋根部３４のその傾斜方向の位置を規定する。これによって、屋根部３４を屋根傾斜方向の所定位置で結合桁１０上に容易に載置することができるとともに、屋根部３４は屋根傾斜方向への移動に対して固定される。なお、屋根パネル４２は、屋根芯材３６および屋根材４４を含んで構成される。
【００３５】
また、ストッパ部５４が、上述のように屋根部３４の下面側に設けた係合部材４０を支持するのではなく、図２に示す屋根部３４の芯材で屋根傾斜方向とは直交する横芯材３８の傾斜方向下方の側面を支持するようにしてもよい。この場合は、係合部材４０を特別に設ける必要はない。これによって、上述の場合と同様に、屋根部３４の屋根傾斜方向の位置を規定し、その屋根傾斜方向への移動が起きないように固定することができる。
【００３６】
固定部５６は、図１、図５、および図６に示すように、その一端は結合桁１０の側面部１８にビス２０等で一体的に固定され、その他端は屋根部３４の傾斜方向に伸びる屋根芯材３６の下面に釘７４等で固定されている。固定部５６は、屋根部３４がいずれの方向にも移動できないように固定する。すなわち、後述する吹き上げ防止部材５８による屋根部３４の結合桁１０への緊結だけでは防げない屋根傾斜方向と交差する方向への屋根部３４の移動も防止することができる。
【００３７】
吊り金具通過孔６６は、図１に示すように、壁部２６の上部の芯材２８に設けられる吊り金具用の貫通孔３０の位置に対応してその上方に位置する結合桁１０に設けられている。この吊り金具通過孔６６と貫通孔３０とによって、吊り金具挿通用の穴部７０が形成される。これによって、結合桁１０を予め取り付けた壁部２６例えば壁パネルであっても、その芯材２８の貫通孔３０を通した後に広がって壁部２６の芯材２８に係合するタイプの吊り金具を、結合桁１０のこの吊り金具通過孔６６および壁部２６の芯材２８に設けられた貫通孔３０を通し、壁部２６の芯材２８に係合させて、壁部２６をクレーン等で吊り降ろして設置することができる。
【００３８】
また、本実施例の結合桁１０は、吹き上げ防止部材５８とともに使用して、壁部２６または梁４６と、屋根芯材３６を含んで構成される屋根部３４とを接合する接合部材として構成してもよい。
【００３９】
吹き上げ防止部材５８は、図１、図５、および図６に示すように、その係合部６０の折り曲げられた一端が、結合桁１０の側面部１８に設けられた穴部すなわち被係合部８０に挿入され回転されて結合桁１０に係合させる。そして、吹き上げ防止部材５８は、その係合部６０と回転自在に結合する第２取付部６２が、釘６４等によって屋根部３４の屋根芯材３６の側面に取り付けられる。これによって、屋根部３４は、吹き上げ防止部材５８によっても固定されるため、屋根部３４が吹き上げられた場合等に、固定部５６による屋根部３４の屋根芯材３６と結合桁１０との間の固定のみでは不足する屋根部３４と結合桁１０との結合強度を補い、屋根部３４の吹き上げ等を防止することができる。なお、吹き上げ防止部材５８は、屋根部３４の吹き上げを防止するために十分な強度をもって屋根部３４の屋根芯材３６に固定され、結合桁１０に係合されている。
【００４０】
なお、吹き上げ防止部材５８は、必ずしも図１および図５などに示した形状でなくともよい。例えば、図１０に示すように、帯状の板材をその中間位置で９０°ねじ曲げたような部材の一端を折り曲げて係合部６０とし、それを結合桁１０の被係合部８０と係合するようにし、他端に釘穴６８を設けて第２取付部６２として、それが屋根部３４の屋根芯材３６に固定されるようにしてもよい。このようなタイプの吹き上げ防止部材５８を使用する場合は、結合桁１０の被係合部８０である開口を上下方向に幾分大きめに設け、係合部６０の折り曲げられた端部を結合桁１０の被係合部８０の斜め下方向から挿入して、結合桁１０と吹き上げ防止部材５８とを係合させる。
【００４１】
図８は、本実施例の結合桁１０の本体部分の１単位の一例を示す斜視図である。この図に示すように、結合桁１０の本体部分は、それぞれ上述した載置部１２、取付部１４、傾斜部１６、側面部１８、および被係合部８０を含んで構成される。この結合桁１０は、取付部１４を有するため、特別な部材を必要とすることなく、前述したように、単に取り付け部１４を壁部２６または梁４６に釘穴８８を介した釘９０等によって固定することによって、壁部２６または梁４６に固定することができる。
【００４２】
また、本実施例の結合桁１０は鋼等の十分な強度を有する金属で形成されている。そのため、木製の結合桁の場合のように、乾燥等による形状の経時変化がなく、この結合桁１０を用いた構造全体に形状変化による影響を及ぼすこともない。
【００４３】
なお、結合桁１０の１単位の長さは、結合桁１０が載置される様々な壁部２６の状況に対応できるように、図９にその一例を示したような、様々な長さのものが用意されている。
【００４４】
また、結合桁１０は、複数を連結して使用することもできる。図８および図９に示した長手方向連結部９８は、隣り合う結合桁１０の傾斜部１６の下面にまたがって、それぞれにセルフタップネジ１００等によって取り付けられ、隣接する結合桁１０同士を接合する。これによって、結合桁１０を連結し、全体として様々な長さの結合桁１０を得ることができるため、最小限の種類の結合桁１０で、必要とする様々な長さに容易に対応することができる。
【００４５】
なお、これらの図では、長手方向連結部９８が、結合桁１０の傾斜部１６に取り付けられる例を示したが、これに限らず、長手方向連結部９８は、隣り合う結合桁のそれぞれの側面部１８や取付部１４などに取り付けられるようにしてもよい。
【００４６】
以上、本発明の実施例を説明したが、本発明は前述した各実施例に限定されるものではなく、本発明の要旨の範囲内または特許請求の範囲の均等範囲内で各種の変形実施が可能である。
【００４７】
例えば、上記実施例では、外壁である壁部２６上に固定された結合桁１０上に屋根部３４の屋根芯材３６が設置される例を示したが、図１１に示したように、内壁である壁部２６上に結合桁１０が固定されるようにし、その上部に屋根部３４が設置されるようにしてもよい。なお、前記実施例に対応する各部には、同図において同一の符号を付し、その説明を省略する。このように内壁である壁部２６上に結合桁１０が固定され、その上に屋根部３４が設置される場合には、同図に示したように、屋根部３４を構成する屋根パネル４２同士の接合部が結合桁１０上に位置することがある。
【００４８】
また、上記実施例では、壁部２６上に結合桁１０が固定される例を示したが、本発明の結合桁１０は、木製の梁４６上に同様に取り付けることもできる。なお、鋼製の梁４６の上部に本発明の結合桁１０を取り付ける場合は、図１２に示したように、木製等の結合部材４８をネジ５０等で鋼製の梁４６に固定し、その結合部材４８の上部に釘９０等で結合桁１０を固定してもよい。この場合においても、結合桁１０が梁４６の上部に固定された結合部材４８に固定される点以外については、上記実施例と同様である。なお、図１２において、対応する各部には上記実施例の場合と同一の符号を付した。
【００４９】
図１３は、鋼製の梁４６上部に木製の結合部材４８を配置し、その上部に結合桁１０を設置した他の例を示している。すなわち、同図は、棟部の梁４６として鋼製の梁４６を用い、その上部に木製の結合部材４８を介在させて結合桁１０を取り付け、２つの異なる傾斜方向の屋根部３４を設置した状態を断面図として示している。この変形例においては、吹き上げ防止部材５８は、帯状の板材を折り曲げて形成され、その一端側は、結合桁１０の取付部１４を貫通し、結合部材４８に圧入される釘９０等によって結合桁１０および結合部材４８に固定され、その端部は鋼製の梁４６の上部を包み込む形状に形成されている。この吹き上げ防止部材５８の他端は上部の屋根部３４の屋根芯材３６に釘６４等によって固定されている。この例では、結合桁１０の一方の側に固定されている吹き上げ防止部材５８はその上方の一方の屋根部３４に固定され、結合桁１０の他方の側に固定されている吹き上げ防止部材５８はその上方の他方の屋根部３４に固定されることによって、棟部の一対の屋根部３４の吹き上げを防止している。
【００５０】
そしてまた、本発明の結合桁１０を鋼製等の金属製の梁４６に取り付ける場合は、必ずしも上述したように壁部２６あるいは鋼製の梁４６の上部に固定された木製の結合部材４８などの木製部分に釘９０等で取り付けなくともよい。例えば、図１４（Ａ）に断面図として示したように結合桁１０を鋼製の梁４６に直接溶接してもよいし、あるいは、図１４（Ｂ）に断面図として示したようにネジ止めによって結合桁１０を梁４６に直接取り付けてもよい。これによって、木製部分を介して鋼製の梁４６に結合桁１０を取り付ける場合に比べ結合桁１０と梁４６との強固な一体性を得ることができる。
【００５１】
さらに、上記実施例では、結合桁１０が一つの傾斜部１６のみを有する例を示したが、図１５（Ａ）〜（Ｆ）に斜視図として示すように、第１傾斜部である傾斜部１６に載置される屋根部（図示せず）に隣接する他の屋根部（図示せず）が載置できる傾斜部である第２傾斜部１０８を設けることもできる。この結合桁１０によれば、２枚の屋根部３４が異なる傾斜をもって隣接する箇所においても結合桁１０を使用することができる。
【００５２】
そしてまた、上記の実施例では、結合桁１０が現場において壁部２６あるいは梁４６に取り付けられる例を示したが、予め工場等において結合桁１０を、壁部２６の一部分を構成する壁パネル本体３２、あるいは梁４６に取り付けて、結合桁付の壁パネル３２あるいは結合桁付の梁４６としておくこともできる。これによって、現場において壁部２６または梁４６に結合桁１０を固定する必要がないため、現場作業を効率化することができる。
【００５３】
【発明の効果】
本発明に係る接合部材によれば、その結合桁の載置部を壁部または梁に載置し、第１取付部をその壁部または梁に取り付けることによって、壁部または梁に固定でき、そして、傾斜部に屋根傾斜方向に沿って伸びる屋根芯材を載置し、吹き上げ防止部材によって屋根部を結合桁に緊結することができる。したがって、この接合部材の壁部または梁への固定は、特別な部材を必要とすることなく、単に取り付け部を釘等によって壁部または梁に固定することによって行うことができる。また、この結合桁は金属製であるため、木製の結合桁の場合のように、乾燥等による形状の経時変化がなく、それを用いた構造全体に形状変化による影響を及ぼすこともない。さらに、本発明の結合桁は金属製であるため、吹き上げ防止部材を含む様々な付属部材を十分な強度をもって結合桁に容易に取り付けることができる。
【００５４】
【００５５】
【００５６】
また、傾斜部には屋根芯材との間の軋みや滑りを防止する滑り防止シートが貼付される。したがって、屋根部の取付の際に屋根部が滑り落ちたりする可能性を減少させることができるとともに、屋根部取付後の屋根の軋み音等を減少させることができる。

[0002]
[Related Art and Problems to be Solved by the Invention]
Conventionally, a wooden connecting girder is used at the top of a wall or beam that supports a sloped roof and intersects the direction of the inclination. In such a case, the roof and the wall or beam are connected. For this reason, it is necessary to use a tight fitting that is a separate member. In the case of a connecting girder installed on the upper part of the beam, this binding metal works by pressing the connecting girder from both sides and pressing the upper roof part from the upper part. It was also necessary for the role of fixing on the beam.
[0003]
Moreover, since the conventional connecting girder is made of wood, the shape may change with time due to drying or the like, which may affect the entire structure using the same.

It is characterized by having.
[0010]
Here, the roof core material means a roof core material that intersects and is supported by the wall portion or the beam. For example, in the panel method, the roof core material is a vertical component that is one component of the roof panel. It is the core material of the direction, and it is a rafter in the conventional construction method. Further, the beam means a steel or wooden girder that receives the core material for the roof. In the panel method, it is a roof beam, and in the conventional method, it is a purlin girder, eaves girder, and purlin. .

Moreover, the said roof part means the roof panel comprised including a roof core material and a face material, for example in a panel construction method, and is a part comprised including a rafter and a roof board in a conventional construction method. Means.
[0012]
According to the joining member according to the present invention, by placing the placing portion of the coupling beam on the wall portion or the beam and attaching the first attachment portion to the wall portion or the beam, it can be fixed to the wall portion or the beam, And the roof core material extended along a roof inclination direction can be mounted in an inclination part, and a roof part can be tied tightly to a joint beam by a blowing-up prevention member. Therefore, the joining member can be fixed to the wall portion or beam by simply fixing the attachment portion to the wall portion or beam with a nail or the like without requiring a special member. In addition, since this coupling girder is made of metal, there is no change in shape due to drying or the like as in the case of a wooden coupling girder, and the entire structure using it is not affected by the shape change. Furthermore, since the coupling beam of the present invention is made of metal, various attachment members including the blow-up preventing member can be easily attached to the coupling beam with sufficient strength.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 is an exploded perspective view showing an example of a structure using the coupling beam 10 of the present embodiment.
