Description

【０００１】
【発明の属する技術分野】
本発明は、筒状の長尺部材と他の部材との接合構造及び接合方法に関する。
【０００２】
【背景の技術】
近年、建物の柱部材や梁部材などの長尺部材として、木質材料からなる筒状の部材が用いられている。この部材は、図４に示すように、木質材料からなる４つの長尺な板状部材を断面視ロ字状の筒状に接合したものである。
【０００３】
このような長尺部材と他の部材とを接合した技術として、特開平０７−０１１７３３号公報に開示のものがある。この公報においては、梁部材として用いられた一方の長尺部材を他の長尺部材に垂直に当接させている。そしてこれら長尺部材の表面によって形成された入り隅部分に平面視略Ｌ字状の接合金物を固定することにより、一方の長尺部材と他の長尺部材とを接合している。
【０００４】
しかしながら、上記のような接合構造においては、長尺部材の表面に接合金物が固定されているため、長尺部材の表面が面一とならず、接合部分の外観を損ねていた。
本発明の課題は、接合金物を外部に露出させずに、筒状の長尺部材と他の部材とを接合することができる接合構造及び接合方法を提供することを目的とする。
【０００５】
【課題を解決するための手段】
以上の課題を解決するため、請求項１記載の発明は、例えば図１〜図４に示すように、長手方向に貫通する孔部を有した筒状の長尺部材（例えば、柱部材１０）と、この長尺部材１０の一方の端部と当接して前記長手方向とほぼ垂直に延在する他の部材（例えば、床部材１１）との接合構造であって、
前記他の部材１１の前記長尺部材１０との当接部分には、この他の部材１１から前記長尺部材１０の他方の端部に向かって突出する棒状部材１２１が設けられ、
前記長尺部材１０は、前記長手方向と垂直な断面が略ロ字状のものであり、木質材料からなる４つの長尺な板状部材１０ａ，…によって形成され、
前記長尺部材１０の内周面には、前記棒状部材１２１と同一直線上に延在する孔部１２２を備えた、前記長尺部材１０と前記他の部材１１とを接合するための第一接合金物１２０が固定され、
前記第一接合金物１２０の前記孔部１２２には、前記棒状部材１２１が挿通され固定されていることを特徴とする。
【０００６】
請求項１記載の発明によれば、長尺部材１０の内周面には第一接合金物１２０が固定され、第一接合金物１２０の孔部１２２には、他の部材１１から突出して設けられた棒状部材１２１が挿通され固定されているので、長尺部材１０の内周面に固定された第一接合金物１２０と、他の部材１１に設けられて第一接合金物１２０の孔部１２２に固定された棒状部材１２１とによって、長尺部材１０と他の部材１１とが互いに接合された状態となっている。従って、接合に用いられる第一接合金物１２０及び棒状部材１２１を外部に露出させずに、木質材料からなる板状部材１０ａ，…によって形成される長尺部材１０と他の部材１１とを接合することができる。よって、従来と異なり、長尺部材の表面に接合金物を固定することなく、長尺部材１０と他の部材１１との表面を面一にしてこれら長尺部材１０と他の部材１１とを接合することができるため、接合部分１の意匠性を高めることができる。
【０００９】
請求項２記載の発明は、例えば図２及び図３に示すように、請求項１記載の接合構造であって、
前記長尺部材（例えば、梁部材３０）の前記一方の端部の開口部には、この開口部とほぼ同じ形状の嵌合部材３３が嵌合しており、
この嵌合部材３３は、前記他の部材（例えば、柱部材３１）に固定されていることを特徴とする。
【００１０】
請求項２記載の発明によれば、長尺部材３０の前記一方の端部の開口部に嵌合した嵌合部材３３が他の部材３１に固定されているので、長尺部材３０と他の部材３１との接合部分３にせん断が生じにくくなっている。従って、嵌合部材３３を設けることよって、長尺部材３０と他の部材３１とを強固に接合することができる。
【００１１】
請求項３記載の発明は、例えば図１（ｂ）に示すように、請求項１又は２記載の接合構造であって、
前記長尺部材は柱部材１０であり、
前記他の部材は基礎２１であることを特徴とする。
【００１２】
請求項３記載の発明によれば、柱部材１０の内周面に固定された第一接合金物１２０と、基礎２１に設けられて第一接合金物１２０の孔部１２２に固定された棒状部材２２１とによって、柱部材１０と基礎２１とが互いに接合された状態となっている。従って、接合に用いられる棒状部材２２１及び第一接合金物１２０を外部に露出させずに、柱部材１０と基礎２１とを接合することができる。
【００１５】
請求項４記載の発明は、例えば図１（ａ）に示すように、長手方向に貫通する孔部を有した筒状の柱部材１０と、この柱部材１０の一方の端部と当接して前記長手方向とほぼ垂直に延在する床部材１１との接合構造であって、
前記床部材１１の前記柱部材１０との当接部分には、この床部材１１から前記柱部材１０の他方の端部に向かって突出する棒状部材１２１が設けられ、
前記床部材１１には、この床部材１１の前記柱部材１０との当接部分と反対側の部位において他の柱部材１０の一方の端部が当接し、かつ前記棒状部材１２１が前記長手方向に沿って貫通して設けられ、
前記柱部材１０の内周面には、前記棒状部材１２１と同一直線上に延在する孔部１２２を備えた、前記柱部材１０と前記床部材１１とを接合するための第一接合金物１２０が固定され、前記第一接合金物１２０の前記孔部１２２には、前記棒状部材１２１が挿通され固定され、
前記他の柱部材１０の内周面には、前記棒状部材１２１と同一直線上に延在する孔部１２２を備えた他の第一接合金物１２０が固定され、
前記棒状部材１２１の一方の端部は、前記他の柱部材１０の内周面に固定された前記他の第一接合金物１２０の前記孔部１２２に挿通され固定されていることを特徴とする。
【００１６】
請求項４記載の発明によれば、柱部材１０の内周面に固定された第一接合金物１２０と、床部材１１に設けられて第一接合金物１２０の孔部１２２に固定された棒状部材１２１とによって、柱部材１０と床部材１１とが互いに接合された状態となっている。従って、接合に用いられる棒状部材１２１及び第一接合金物１２０を外部に露出させずに、柱部材１０と床部材１１とを接合することができる。また、他の柱部材１０が床部材１１に接合されて、前記柱部材１０と他の柱部材１０とが床部材１１を間に介在させて上下方向に接合された状態となっている。従って、２本の柱部材１０，１０が、床部材１１との接合部分のずれを互いに拘束した状態となるため、柱部材１０，１０と床部材１１とを強固に接合することができる。
【００１９】
請求項５記載の発明は、例えば図２及び図３に示すように、長手方向に貫通する孔部を有した筒状の梁部材３０と、この梁部材３０の一方の端部と当接して前記長手方向とほぼ垂直に延在する柱部材３１との接合構造であって、
前記柱部材３１の前記梁部材３０との当接部分には、この柱部材３１から前記梁部材３０の他方の端部に向かって突出する棒状部材１２１が設けられ、
前記梁部材３０の内周面には、前記棒状部材１２１と同一直線上に延在する孔部１２２を備えた、前記梁部材３０と前記柱部材３１とを接合するための第一接合金物１２０が固定され、前記第一接合金物１２０の前記孔部１２２には、前記棒状部材１２１が挿通され固定され、
前記柱部材３１は、木質材料からなる４つの長尺な板状部材３１ａ，…によって形成された、平断面が略ロ字状のものであり、
この柱部材３１の内周面には、前記棒状部材１２１と一体化された第二接合金物３２３が固定されていることを特徴とする。
【００２０】
請求項５記載の発明によれば、梁部材３０の内周面に固定された第一接合金物１２０と、柱部材３１に設けられて第一接合金物１２０の孔部１２２に固定されると同時に柱部材３１の内周面の第二接合金物３２に一体化された棒状部材１２１とによって、梁部材３０と柱部材３１とが互いに接合された状態となっている。従って、木質材料からなる板状部材３１ａ，…によって形成される柱部材３１と、梁部材３０とを、第一接合金物１２０及び第二接合金物３２３並びに棒状部材１２１を外部に露出させずに接合することができる。
【００２１】

前記他の棒状部材１２１は、前記他の第一接合金物１２０の前記孔部１２２に挿通され固定され、かつ前記第二接合金物３２３と一体化していることを特徴とする。
【００２２】
請求項６記載の発明によれば、前記梁部材３０及び他の梁部材３０と柱部材３１とが互いに接合された状態となっている。従って、接合に用いられる第一接合金物１２０及び第二接合金物３２３並びに棒状部材１２１を外部に露出させずに、柱部材３１と複数の梁部材３０とを接合することができる。また、前記梁部材３０と柱部材３１との接合に用いられる棒状部材１２１と、他の梁部材３０と柱部材３１との接合に用いられる他の棒状部材１２１とが同一の第二接合金物３２３と一体化しているため、この第二接合金物３２３を介して前記梁部材３０と他の梁部材３０とが互いに接合された状態となっている。従って、梁部材３０，３０どうしが互いに拘束された状態となるため、これら梁部材３０，３０を強固に固定することができる。
【００２３】
請求項７記載の発明は、例えば図１〜図４に示すように、長手方向に貫通する孔部を有した筒状の長尺部材１０と、この長尺部材１０の一方の端部と当接して前記長手方向とほぼ垂直に延在する他の部材１１とを接合する接合方法であって、
前記長尺部材１０は、前記長手方向と垂直な断面が略コ字状のコ字状部材１０ｂと、前記長手方向に沿って前記コ字状部材１０ｂの開口部に固定される板状部材１０ａとからなり、
前記他の部材１１の前記長尺部材１０との当接部分には、この他の部材１１から前記長尺部材１０の他方の端部に向かって突出する棒状部材１２１が設けられており、
前記コ字状部材１０ｂの内側の面に、前記棒状部材１２１と同一直線上に延在する孔部１２２を備えた、前記長尺部材１０と前記他の部材１１とを接合するための第一接合金物１２０を固定し、
次に、前記コ字状部材１０ｂの一方の端部を前記他の部材１１に当接させるとともに、前記第一接合金物１２０の孔部１２２に前記棒状部材１２１を挿通して固定し、
次に、前記長手方向に沿って前記コ字状部材１０ｂの前記開口部に前記板状部材１０ａを固定することを特徴とする。
【００２４】
請求項７記載の発明によれば、第一接合金物１２０が固定されたコ字状部材１０ｂの一方の端部を他の部材１１に当接させ、第一接合金物１２０の孔部１２２に棒状部材１２１を挿通して固定することにより、それぞれのコ字状部材１０ｂの内側の面に固定された第一接合金物１２０と、他の部材１１に設けられて第一接合金物１２０の孔部１２２に挿通され固定された棒状部材１２１とによってコ字状部材１０ｂと他の部材１１とが互いに接合された状態となる。更に、コ字状部材１０ｂの開口部に板状部材１０ａを固定することにより、長尺部材１０と他の部材１１とが互いに接合された状態となる。従って、接合に用いられる第一接合金物１２０及び棒状部材１２１を外部に露出させずに、長尺部材１０と他の部材１１とを接合することができる。よって、従来と異なり、長尺部材の表面に接合金物を固定することなく、長尺部材１０と他の部材１１との表面を面一にして、これら長尺部材１０と他の部材１１とを接合することができるため、接合部分１の意匠性を高めることができる。
【００２５】
【発明の実施の形態】
以下、図を参照して本発明の実施の形態を詳細に説明する。
〔第一の実施の形態〕
図１（ａ）は、本第一の実施の形態における接合構造を適用した、柱部材と床部材１１との接合部分１の斜視図である。なお、本第一の実施の形態においては、長尺部材を柱部材１０とし、他の部材を床部材１１として説明する。
【００２６】
接合部分１は、図１（ａ）に示すように、水平に延在する床部材１１と、この床部材１１を間に介在させて上下に配置された筒状の柱部材１０，１０と、これら床部材１１と柱部材１０，１０とを接合する接合部材１２等とから一体に構成されている。
【００２７】
床部材１１は、上下方向に貫通する貫通孔部（図示せず）を備えている。この床部材１１は、本実施の形態においては、パネル工法における床パネルである。即ち、床部材１１は、縦框材と横框材とが矩形状に組み立てられるとともに、この矩形枠の内部に補強桟材が縦框材と平行な方向に組まれて枠体が形成され、この枠体の表面に合板やフローリング等の面材が貼設されたものである。
【００２８】
柱部材１０は、図４（ａ）に示すように、上下方向に貫通する孔部を有した平面視ロ字状のものである。この柱部材１０は、木質材料からなる４つの長尺な板状部材１０ａ，…を、釘やビス、接着剤などを用いて互いに接合することによって形成されている。より詳細には、柱部材１０は、３つの板状部材１０ａ，…を互いに接合することによって予め形成された平面視略コ字状のコ字状部材１０ｂと、上下方向に沿ってコ字状部材１０ｂの開口部に固定された板状部材１０ａとから形成されている。なお、本実施の形態においては、板状部材１０ａは、ＬＶＬによって形成されている。ＬＶＬとは、Laminated Veneer Lumber のことであり、材質が均一であり、温度・湿度による変形が少なく、高品質・高精度であって、大きさ・形状の自由度が高いという特性を具備するものである。
このような柱部材１０，１０は、床部材１１の貫通孔部の上下端部を柱部材１０の端部の開口部内に露出させるように、床部材１１を挟んで直線状に配置されている。
【００２９】
接合部材１２は、第一接合金物１２０，…と、両端部に雄ネジ部１２３が形成された棒状部材１２１，…と、各棒状部材１２１の雄ネジ部１２３，１２３と互いに螺合したナット１２４，１２４と、各棒状部材１２１に遊嵌されたリング状のワッシャー１２５，１２５等とからなる。
【００３０】
第一接合金物１２０は、上下方向に貫通して設けられた孔部１２２，１２２を両側部に備えた平板状のものである。孔部１２２は、床部材１１に設けられた貫通孔部と連通するものである。この第一接合金物１２０は、その両側部の孔部１２２，１２２で挟まれた部分において、柱部材１０の互いに対向する一方の内周面と他方の内周面とに、ビスや釘などによってそれぞれ固定されている。
【００３１】
棒状部材１２１は、上下に並んで配置された第一接合金物１２０の孔部１２２に床部材１１の貫通孔部を介して挿通されている。つまり、棒状部材１２１は、床部材１１の柱部材１０との当接部分から突出した状態に設けられて、第一接合金物１２０，１２０の孔部１２２，１２０に挿通されている。孔部１２２に挿通された棒状部材１２１は、その両端部の雄ネジ部１２３においてナット１２４と螺合することにより第一接合金物１２０に固定されている。ナット１２４と第一接合金物１２０の孔部１２２の端部との間にはワッシャー１２５が介在しており、ナット１２４が緩むのを防いでいる。
そして、これら柱部材１０の内周面に固定された第一接合金物１２０と、第一接合金物１２０の孔部１２２に固定された棒状部材１２１等とによって、床部材１１と各柱部材１０とが互いに接合された状態となっている。
【００３２】
次に、上記のような接合部分１を形成する手順について説明する。
まず、床部材１１の柱部材１０と当接するべき部分に貫通孔部を複数設ける。このとき、複数の貫通孔部が柱部材１０の前記一方の内周面と前記他方の内周面とにそれぞれ沿うようにする。
次に、柱部材１０の一部を構成するコ字状部材１０ｂの両側壁部の内側の面に、ビスや釘などによって第一接合金物１２０，１２０をそれぞれ固定する。
次に、第一接合金物１２０が固定された２つのコ字状部材１０ｂ，１０ｂを、貫通孔部を間に挟んで床部材１１の上下面にそれぞれ当接させる。
次に、上下に連通した第一接合金物１２０，１２０の孔部１２２，１２２に、貫通孔部を介して棒状部材１２１を挿通する。また、孔部１２２に挿通された棒状部材１２１の両端部の雄ネジ部１２３，１２３にそれぞれワッシャー１２５を遊嵌した後に、ナット１２４を螺合させ、棒状部材１２１を第一接合金物１２０の孔部１２２に固定する。これにより、それぞれのコ字状部材１０ｂの内側の面に固定された第一接合金物１２０と、第一接合金物１２０の孔部１２２に固定された棒状部材１２１等とによって２本のコ字状部材１０ｂ，１０ｂはそれぞれ床部材１１と互いに接合された状態となる。
次に、コ字状部材１０ｂの開口部、つまりコ字状部材１０ｂの開口側の側部に板状部材１０ａを固定する。これにより、床部材１１と２本の柱部材１０，１０とが互いに接合された状態となる。
【００３３】
以上のように形成された接合部分１の接合構造によれば、それぞれの柱部材１０の内周面には第一接合金物１２０，１２０が固定され、上下に並んで配置された第一接合金物１２０，１２０の孔部１２２，…には、これら第一接合金物１２０，１２０と互いに係合し合う棒状部材１２１が床部材１１の貫通孔部を介して挿通され固定されているので、それぞれの柱部材１０の内周面に固定された第一接合金物１２０，１２０と、第一接合金物１２０の孔部１２２，１２０に固定された棒状部材１２１，…等とによって、床部材１１と各柱部材１０とが互いに接合された状態となっている。従って、接合に用いられる第一接合金物１２０，…及び棒状部材１２１，…等を外部に露出させずに、柱部材１０，１０と床部材１１とを接合することができる。よって、従来と異なり、柱部材の表面に接合金物を固定することなく、柱部材１０，１０と床部材１１との表面を面一にしてこれら柱部材１０，１０と床部材１１とを接合することができるため、接合部分１の意匠性を高めることができる。
また、２本の柱部材１０，１０が棒状部材１２１を介して、床部材１１を間に介在させて上下方向に接合され、床部材１１との接合部分のずれを互いに拘束した状態となるため、柱部材１０と床部材１１とを強固に接合することができる。
【００３４】
また、柱部材１０は、ＬＶＬからなる板状部材１０ａ，…によって形成されているので、第一接合金物１２０を容易に固定可能である。従って、柱部材１０と床部材１１とを容易に接合することができる。更に、柱部材１０は、高い強度を備えているとともに、変形しにくくなっているため、柱部材１０に第一接合金物１２０を強固に固定することができるとともに、床部材１１に当接する柱部材１０の端部に変形を生じさせることなく、柱部材１０と床部材１１とを強固に固定することができる。
【００３５】
〔第二の実施の形態〕
次に、本発明を適用した第二の実施の形態を、図１（ｂ）を参照して説明する。
図１（ｂ）は、本発明における接合構造を適用した、柱部材１０と基礎２１との接合部分２の斜視図である。なお、本第二の実施の形態においては、長尺部材を柱部材１０とし、他の部材を基礎２１として説明する。またなお、上記第一の実施の形態と同様の構成要素には同一の符号を付し、その説明を省略する。
【００３６】
接合部分２は、図１（ｂ）に示すように、基礎２１と、この基礎２１の上部に配置され、上下方向に貫通する孔部を有した筒状の柱部材１０と、これら基礎２１と柱部材１０とを接合する接合部材２２等とから一体に構成されている。
【００３７】
基礎２１は、地盤上に設けられた布基礎である。
接合部材２２は、柱部材１０の互いに対向する一方の内周面と他方の内周面とに固定された第一接合金物１２０，…と、上方に突出した状態で基礎２１に設けられるとともに上端部に雄ネジ部２２３が形成された棒状部材２２１と、この棒状部材２２１の雄ネジ部２２３と互いに螺合したナット１２４と、棒状部材２２１と遊嵌されたリング状のワッシャー１２５等とからなる。
【００３８】
棒状部材２２１は、第一接合金物１２０の孔部１２２に下方から挿通されている。孔部１２２に挿通された棒状部材２２１は、その上端部の雄ネジ部２２３においてナット１２４と螺合することにより第一接合金物１２０に固定されている。ナット１２４と第一接合金物１２０の孔部１２２の端部との間にはワッシャー１２５が介在している。
そして、これら第一接合金物１２０と棒状部材２２１等とによって、基礎２１と柱部材１０とが互いに接合された状態となっている。
【００３９】
次に、以上のような接合部分２を形成する手順について説明する。
まず、柱部材１０の一部を構成するコ字状部材１０ｂの両側壁部の内側の面に、それぞれ第一接合金物１２０をビスや釘などによって固定する。
次に、第一接合金物１２０が固定されたコ字状部材１０ｂを基礎２１の上部に配置するとともに、基礎２１の上方に突出した棒状部材２２１を第一接合金物１２０の孔部１２２に挿通する。
次に、第一接合金物１２０の孔部１２２に挿通された棒状部材２２１の上端部の雄ネジ部２２３にワッシャー１２５を遊嵌した後に、ナット１２４を螺合させ、棒状部材２２１を第一接合金物１２０の孔部１２２に固定する。これにより、コ字状部材１０ｂの内側の面に固定された第一接合金物１２０と、基礎２１に設けられた棒状部材２２１とによってコ字状部材１０ｂと基礎２１とが互いに接合された状態となる。
次に、コ字状部材１０ｂの開口部に板状部材１０ａを固定する。これにより、柱部材１０と基礎２１とが互いに接合された状態となる。
【００４０】
以上のように形成された接合部分２の接合構造によれば、柱部材１０の内周面には第一接合金物１２０，１２０が固定され、各第一接合金物１２０の孔部１２２，１２２には、基礎２１から突出して設けられた棒状部材２２１，…が挿通されて固定されているので、これら第一接合金物１２０，１２０と棒状部材２２１，…等とによって、基礎２１と柱部材１０とが互いに接合された状態となっている。従って、接合に用いられる棒状部材２２１，…及び第一接合金物１２０，１２０等を外部に露出させずに、基礎２１と柱部材１０とを接合することができる。
【００４１】
〔第三の実施の形態〕
次に、本発明を適用した第三の実施の形態を、図２を参照して説明する。
図２は、本発明における接合構造を適用した、柱部材３１と梁部材３０との接合部分３の斜視図である。なお、本第三の実施の形態においては、長尺部材を梁部材３０とし、他の部材を柱部材３１として説明する。またなお、上記第一の実施の形態と同様の構成要素には同一の符号を付し、その説明を省略する。
【００４２】
接合部分３は、図２に示すように、柱部材３１と、この柱部材３１を間に介在させて左右に配置され、左右方向に貫通する孔部を有した筒状の梁部材３０，３０と、梁部材３０の端部の開口部と嵌合した嵌合部材３３と、柱部材３１と梁部材３０とを接合する接合部材３２等とから一体に構成されている。

【００４９】
次に、上記のような接合部分３を形成する手順について説明する。
まず、第二接合金物３２３が内周面に固定された状態となるように柱部材３１を形成する。具体的には、例えば、まず、第二接合金物３２３に棒状部材１２１を溶接し、溶接により棒状部材１２１と一体化された第二接合金物３２３をビスや釘などによって矩形板材に固定する。また、柱部材３１を構成する４つの板状部材３１ａ，…のうち、２つの板状部材３１ａ，３１ａの上端部にそれぞれ貫通孔部を形成する。次に、貫通孔部が設けられた板状部材３１ａ，３１ａが互いに対向するように、４つの板状部材３１ａ，…を接合し、柱部材３１を形成する。このとき、２つの矩形板３１１，３１１が柱部材３１の内周面に固定され、かつ第二接合金物３２３と一体化された棒状部材１２１が柱部材３１の左右に突出した状態とする。

【００５２】
また、柱部材３１及び梁部材３０は、ＬＶＬからなる板状部材３１ａ，３０ａによって形成されているので、第一及び第二接合金物１２０，３２３を容易に固定可能である。従って、柱部材３１と梁部材３０とを容易に接合することができる。更に、柱部材３１及び梁部材３０は、高い強度を備えているとともに、変形しにくくなっているため、第二接合金物３２３を柱部材３１に強固に固定することができ、かつ第一接合金物１２０を梁部材３０に強固に接合することができる。更に、梁部材３０と柱部材３１との当接部分に変形が生じにくい。以上により、柱部材３１と梁部材３０とをより強固に固定することができる。
【００５３】
更に、梁部材３０の端部の開口部に嵌合した嵌合部材３３が柱部材３１に固定されているので、梁部材３０と柱部材３１との接合部分にせん断が生じにくくなっている。従って、嵌合部材３３を設けることよって、梁部材３０と柱部材３１とをより強固に固定することができる。

【００５６】
更に、棒状部材１２１は、柱部材３１の内周面の第二接合金物３２３に溶接されることによって第二接合金物３２３と一体化されていることとして説明したが、梁部材３０と柱部材３１とが強固に接合される限りにおいて第二接合金物３２３と一体化されないこととしてもよい。例えば、第二接合金物３２３の両側部に、左右方向に延在する孔部を設け、この孔部に棒状部材１２１を挿通し、棒状部材１２１と第二接合金物３２３とが互いに係合し合うようにしても良い。また、棒状部材１２１を、第二接合金物３２３の上面に配置し、この第二接合金物３２３によって支持されることとしても良い。
