Description

【0001】
【発明の属する技術分野】
本発明は、建物の各階層部間に、ロッキング構法によって既製壁体を結合する技術に関するものである。
【0002】
【従来の技術】
建築物において、PCa(プレキャストコンクリート)版からなる化粧壁部材(カーテンウォール)やPCaからなる内部間仕切壁等の既製壁体を、バルコニーや躯体外周梁、あるいは梁など、建物の階層部に結合する技術として、乾式ロッキング構法によるものが知られている。
【0003】
乾式ロッキング構法は、各既製壁体の上端部及び下端部が、鋼材製のブラケットやボルトからなる上下変位可能な乾式継手材を介して、バルコニーなどの床部や躯体外周梁に結合され、地震力や風圧などによる層間水平変位に対して、各既製壁体が、継手材のボルトを支点として微小回転することによって、既製壁体に加わる強制変位を吸収し、PCa等からなる既製壁体の損傷や崩落の防止を図るものである。
【0004】
しかしながら、従来の技術によるロッキング構法においては、既製壁体の上端部及び下端部に取り付けられる乾式継手材が、複数の金具及びボルト等で構成され、この金具が既製壁体の表面に露出しているため、外観上、好ましくなかった。また、前記金具を隠すためには、仕上材が別途必要になり、施工コストの上昇を来していた。更に、このような金具や仕上材を取り付けるための余分な空間が必要であった。
【0005】
【発明が解決しようとする課題】
本発明は、上記のような問題に鑑みてなされたもので、その技術的課題は、ロッキング構法による建物の階層部と既製壁体との結合において、既製壁体の表面に露出する金具を使用する必要がなく、収まりの良い結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】
上述した技術的課題を有効に解決するための手段として、請求項1の発明に係る建物の階層部と既製壁体との結合構造は、既製壁体の上端部及び下端部を幅方向両側へ偏在する位置で上下の階の階層部に結合するジョイントを備え、前記各ジョイントが、前記既製壁体及びその上下の階の階層部のうち一方に埋設固定されると共に他方に形成された継手孔に挿入された軸状継手材と、前記継手孔内の軸状継手材の周囲に設けられこの軸状継手材に上下に追従変位可能な変形追従材と、この変形追従材と前記継手孔の間に充填され固結した充填材と、からなる。
【0007】
なお、本発明において適用される既製壁体とは、PCa版あるいは鋼製などの化粧壁(カーテンウォール)、間仕切り壁、飾り柱など、各階層部間に結合される剛性の大きいパネル状あるいは直方体状の要素を総称するものである。
【0008】
請求項2の発明に係る建物の階層部と既製壁体との結合構造は、請求項1に記載の構成において、既製壁体の下端部における幅方向中間部が、その下の階層部に、前記既製壁体の重量による鉛直荷重を受ける支持部材を介して支持される。
【0009】
請求項3の発明に係る建物の階層部と既製壁体との結合構造は、請求項1に記載の構成において、階層部が立上り壁を有し、軸状継手材又は継手孔がこの立上り壁に設けられる。
【0010】
請求項4の発明に係る建物の階層部と既製壁体との結合構造は、請求項1に記載の構成において、変形追従材が、軸状継手材の上下相対変位によって剪断変形されるエラストマ材料からなる。
【0011】
【発明の実施の形態】
図1は、本発明に係る建物の階層部と既製壁体との結合構造を、アルミ手摺付きバルコニーと、既製壁体であるパネル状PCa壁との結合部に適用した好ましい実施の形態を示すもので、(A)は内部構造の一部を表す正面図、(B)は(A)におけるB1−B2−B3−B4線で切断した断面図である。また、図2は、図1におけるII−II線で切断した拡大断面図、図3は図1におけるIII−III線で切断した拡大断面図、図4は図1におけるIV−IV線で切断した拡大断面図である。
【0012】
まず図1において、参照符号1は建物のコンクリート躯体における階層部としてのバルコニーで、1はn階のバルコニー、1n+1は、その上階(n+1階)のバルコニーである。参照符号2は、予めコンクリートで成形され、各階のバルコニー1,1n+1,…の端縁間に取り付けられた、既製壁体としてのパネル状PCa(プレキャストコンクリート)柱で、2n−1は、バルコニー1とその下階(n−1階)のバルコニーとの間に設けられたパネル状PCa壁2は、バルコニー1,1n+1間に設けられたパネル状PCa壁2n+1は、バルコニー1n+1とその上階(n+2階)の図示されていないバルコニーとの間に設けられたパネル状PCa柱である。
【0013】
各バルコニー1及びパネル状PCa壁2の外側面には、外壁タイル3が貼られている。このタイル3は、各バルコニー1とパネル状PCa壁2との間の水平目地部では、上下に互いに不連続とする。また、バルコニー1の端縁1a上には、図1(A)におけるパネル状PCa壁2の左右両側に位置して、アルミ手摺11が立設される。
【0014】
参照符号5は、バルコニー1とその上のパネル状PCa壁2の下端部2aとを結合する第一のジョイント、参照符号6は、バルコニー1とその下階のパネル状PCa壁2の上端部2bとを結合する第二のジョイント、参照符号7は、バルコニー1上にパネル状PCa壁2の重量による鉛直荷重を支持するための支持部材であり、これら第一及び第二のジョイント5,6と支持部材7によって、地震力や風圧などによる建物の層間水平変位に応じてパネル状PCa壁2の微小回転を許容するロッキングジョイント機構が構成されている。
【0015】
詳しくは、第一のジョイント5は、パネル状PCa壁2の下端部2aにおける幅方向両端近傍部分を、その下のバルコニー1の端縁1a上に結合するように、各パネル状PCa壁2につき左右一対設けられている。各第一のジョイント5は、図2に拡大して示されるように、バルコニー1の端縁1aの上部に開設された継手孔51と、このバルコニー1の上に配置されるパネル状PCa壁2の下端部2aに上部52aが埋設固定されると共に下部52bが前記継手孔51に挿入された軸状継手材52と、この軸状継手材52の下部52b周囲に設けられた変形追従材53と、この変形追従材53と前記継手孔51の間に充填され固結した充填材54とで構成される。
【0016】
軸状継手材52は、例えば外径がφ20mm程度の丸鋼鉄筋からなり、パネル状PCa壁2の製作の際に、その下端部2aから突出した状態に一体的に埋設されたものである。一方、継手孔51は、バルコニー1を現場打ちコンクリートで施工する際、又はプレキャストコンクリートで製作する際に、軸状継手材52との結合位置に対応して形成されたものであって、その内周面にはスパイラルチューブ51aが設けられている。このスパイラルチューブ51aは、バルコニー1の施工の際に、その鉄筋12の端部に固定されたカップ状の金具であって、寸法誤差や施工誤差を吸収する目的で、軸状継手材52よりも十分に大径に形成される。
【0017】
変形追従材53はエラストマ(ゴム状弾性材料)からなるものであって、詳しくはパネル状PCa壁2の下端部2aから突出した軸状継手材52の下部52bに外挿された例えばクロロプレンゴムからなるゴムチューブ53aと、軸状継手材52の下側に配置されゴムチューブ53aの下端内周に設けられた発泡ネオプレンゴムからなるスポンジ53bとで構成される。なお、ゴムチューブ53aの径方向肉厚は、後述する層間水平変位に伴う軸状継手材52の上下変位による最大剪断変形量が、許容剪断変形量未満になるように、適切に設定される。
【0018】
充填材54は、湿式材料、例えばモルタルあるいはグラウトなど、樹脂系やセメント系の固結材からなるものであって、継手孔51のスパイラルチューブ51aとその内周に挿入された軸状継手材52の外周の変形追従材53との隙間を埋め、変形追従材53の外周を固定するものである。すなわち、この充填材54は、パネル状PCa壁2の取付に際して、予め変形追従材53を外挿した軸状継手材52の下部52bを継手孔51に挿入した後、その隙間に充填され、固結したものである。
【0019】
第二のジョイント6は、パネル状PCa壁2の上端部2bを、その上のバルコニー1の端縁1a上に、第一のジョイント5よりも幅方向中央寄りの位置(又は外側の位置)で結合するように、各パネル状PCa壁2につき左右一対設けられている。この第二のジョイント6も、基本的には第一のジョイント5と同様の構成を有するものであって、すなわち図3に拡大して示されるように、バルコニー1の端縁1aに鉛直方向に貫通して開設された継手孔61と、このバルコニー1の下側のパネル状PCa壁2の上端部2bに下部62aが埋設固定されると共に上部62bが前記継手孔61に挿入された軸状継手材62と、この軸状継手材62の上部62bの周囲に設けられた変形追従材63と、この変形追従材63と前記継手孔61の間に充填され固結した充填材64とで構成される。
【0020】
軸状継手材62は、例えば外径がφ20mm程度の丸鋼鉄筋からなり、パネル状PCa壁2の製作の際に、その上端部2bから突出した状態に一体的に埋設されたものである。一方、継手孔61は、バルコニー1を現場打ちコンクリートで施工する際、又はプレキャストコンクリートで製作する際に、軸状継手材62との結合位置に対応して形成されたものであって、その内周面にはスパイラルチューブ61aが設けられている。このスパイラルチューブ61aは、バルコニー1の施工の際に、その鉄筋12の端部に固定された円筒状の金具であって、寸法誤差や施工誤差を吸収する目的で、軸状継手材62よりも十分に大径に形成される。
【0021】
変形追従材63も、先に説明した第一のジョイント5の変形追従材53と同様、パネル状PCa壁2の上端部2bから突出した軸状継手材62の上部62bに外挿された例えばクロロプレンゴムからなるゴムチューブ63aと、軸状継手材62の上側に配置されゴムチューブ63aの上端内周に設けられた発泡ネオプレンゴムからなるスポンジ63bとで構成される。また、ゴムチューブ63aの径方向肉厚も、後述する層間水平変位に伴う軸状継手材62の上下変位によって受ける最大剪断変形量が、許容剪断変形量未満になるように、適切に設定される。
【0022】
充填材64は、モルタルあるいはグラウトなど、樹脂系やセメント系の固結材からなるものであって、継手孔61のスパイラルチューブ61aとその内周に挿入された軸状継手材62の外周の変形追従材63との隙間を埋め、変形追従材63の外周を固定するものである。すなわち、この充填材64は、パネル状PCa壁2の取付に際して、予め変形追従材63を外挿した軸状継手材62の上部62bに継手孔61を有するバルコニー1を嵌めた後で、その隙間に充填され、固結したものである。
【0023】
なお、参照符号65は、未硬化の充填材64を充填する際に、この充填材64が、継手孔61(スパイラルチューブ61a)の下端から、バルコニー1とその下側のパネル状PCa壁2との間(水平目地)へ流出してしまうのを防止する目的で、継手孔61の下端開口を塞ぐように前記水平目地内へ挿入された、発泡ネオプレンゴムからなるスポンジである。
【0024】
支持部材7は、バルコニー1の端縁1a上にパネル状PCa壁2の下端部2aの幅方向中央部を支持するものであって、図4に拡大して示されるように、バルコニー1の端縁1aの上部に埋設された金属製のアンカー71と、このアンカー71に軸心の周りに回転自在に取り付けられたボルト72と、パネル状PCa壁2の下端部2aに一体的に埋設され前記ボルト72に螺合された袋ナット73とからなる。なお、ボルト72と袋ナット73による螺合構造としたのは、パネル状PCa壁2のレベル調整を行うためであり、レベル調整が不要な場合は、単に支持金具を突設させたものでも良い。
【0025】
なお、図2乃至図4における参照符号4は、バルコニー1とパネル状PCa壁2との間の水平目地に介在されたシーリング材、4aは、シーリング材4の内側に設けられたバックアップ材である。
【0026】
上述の構成によれば、第一のジョイント5、第二のジョイント6及び支持部材7は、その構成要素が、バルコニー1とパネル状PCa壁2との水平目地の内部に収まっていて、外側への露出部分が存在しない。このため、収まりが良く、外観上の美観を向上させることができ、従来のような金具を隠すための仕上材も不要となる。
【0027】
しかも、施工に際して、複数の金具を取り付けるための多くのボルト止め作業等もなくなるので、コストを低減することができる。また、寸法誤差や施工誤差による継手孔51,61と、軸状継手材52,62(変形追従材53,63)との位置ずれがあっても、継手孔51,61と変形追従材53,63の間を充填材54,64で埋める構成であるため、複数の金具からなる従来のジョイントのようなガタつきが発生することもない。
【0028】
図5は、本形態の結合構造において、層間水平変位によるパネル状PCa柱のロッキング動作を示す説明図、図6はパネル状PCa柱のロッキング動作に伴う第一及び第二のジョイントの動作を示す説明図である。
【0029】
すなわち、図5(A)に示される通常状態から、建物が地震力や風圧などによる水平荷重を受けることによって、図5(B)に示されるように、n階のスラブ(バルコニー1)に対して、n+1階のスラブ(バルコニー1n+1)が、矢印Fで示される方向への相対的な水平変位(層間水平変位)を生じると、両バルコニー1,1n+1間で、パネル状PCa壁2が支持部材7を支点にして微小回転(ロッキング)される。このとき、左右各一対の第一及び第二のジョイント5,6によるパネル状PCa壁2の結合部a〜dは、局部的に見れば、ほぼ上下方向の変位となる。
【0030】
詳しくは、図5(B)に示される層間水平変位では、結合部aにおける第二のジョイント6は、その軸状継手材62が、図6(A)に示される通常位置から、図6(B)に示されるように、パネル状PCa壁2とその上側のバルコニー1n+1との隙間Gを減少させる方向へ僅かに上方変位する。また、図5(B)の結合部cにおける第一のジョイント5は、その軸状継手材52が、図6(C)に示される通常位置から、図6(D)に示されるように、パネル状PCa壁2とその下側のバルコニー1との隙間Gを増大させる方向へ僅かに上方変位することになる。
【0031】
一方、図示は省略するが、図5(B)の結合部bでは、第二のジョイント6の軸状継手材62が、パネル状PCa壁2とその上側のバルコニー1n+1との隙間を増大するように下方変位し、結合部dでは、第一のジョイント5の軸状継手材52が、パネル状PCa壁2とその下側のバルコニー1との隙間を減少するように下方変位することになる。
【0032】
このため、変形追従材53,63のゴムチューブ53a,63aは、上下に相対変位する軸状継手材52,62と充填材54,64との間で変形を受けることになり、その変形は剪断方向であるため、低ばねとなる。また、変形追従材53,63のスポンジ53b,63bは変形が圧縮方向となるが、発泡体であるため、そのばね定数も十分に低く抑えられる。したがって、変形追従材53,63の柔軟な変形性によって、バルコニー1,1n+1との間でパネル状PCa壁2が受ける強制変形が有効に吸収される。
【0033】
なお、各バルコニー1及びパネル状PCa壁2の外側面に貼られた外壁タイル3は、各バルコニー1とパネル状PCa壁2との間の水平目地部では、上下に互いに不連続であるため、上述したパネル状PCa壁2のロッキング動作によって前記水平目地部での外壁タイル3の破壊や剥離を生じるおそれはない。
【0034】
また、パネル状PCa壁2の重量による鉛直荷重を、剛性の大きい支持部材7を介して支持するため、通常状態において、第一及び第二のジョイント5,6における変形追従材53,63のゴムチューブ53a,63aには、余分な剪断応力が常時作用することがなく、スポンジ53b,63bに余分な圧縮あるいは引張応力が常時作用することがない。したがって、変形追従材53,63の永久歪等による劣化を防止することができる。
【0035】
次に、図7は、本発明に係る建物の階層部と既製壁体との結合構造を、PCa手摺付きバルコニーと、既製壁体であるパネル状PCa柱との結合部に適用した、好ましい他の実施の形態を示すもので、(A)は内部構造の一部を表す正面図、(B)は(A)におけるB1−B2−B3−B4−B5−B6線で切断した断面図である。
【0036】
この形態において、建物のコンクリート躯体における階層部としてのバルコニー1(1,1n+1,…)は、その端縁に沿って、予めコンクリートで成形された立上り壁としてのPCa手摺13が一体に接合されたものである。既製壁体としてのパネル状PCa壁2は、PCa手摺13の上端面と、その上階のバルコニー1の端部下面との間に取り付けられている。
【0037】
各バルコニー1、PCa手摺13及びパネル状PCa壁2の外側面には、外壁タイル3が貼られている。この外壁タイル3は、各バルコニー1とその下のパネル状PCa壁2との間の水平目地部、及びPCa手摺13とその上のパネル状PCa壁2との間の水平目地部では、上下に互いに不連続とする。また、前記各水平目地部には、シーリング材4及びそのバックアップ材が介在されている。
【0038】
第一のジョイント5は、PCa手摺13とその上のパネル状PCa壁2の下端部2aとを結合しており、第二のジョイント6は、バルコニー1とその下階のパネル状PCa壁2の上端部2bとを結合している。また、支持部材7は、PCa手摺13上にパネル状PCa壁2の重量による鉛直荷重を支持するものである。そしてこれら第一及び第二のジョイント5,6と支持部材7によって、地震力や風圧などによる建物の層間水平変位に応じてパネル状PCa壁2の微小回転を許容するロッキングジョイント機構が構成されている。
【0039】
第一のジョイント5は、PCa手摺13の上部に形成された継手孔51と、このPCa手摺13の上に配置されるパネル状PCa壁2の下端部2aに上部が埋設固定されて下部が前記継手孔51に挿入された軸状継手材52と、この軸状継手材52の下部周囲に設けられた変形追従材53と、この変形追従材53と前記継手孔51の間に充填され固結した充填材54とで構成される。そして、これら継手孔51、軸状継手材52、変形追従材53、充填材54等の要素は、基本的には、先に説明した図2と同様のものである。
【0040】
第二のジョイント6は、バルコニー1の端縁とPCa手摺13との結合部に形成された継手孔61と、このバルコニー1の下階側のパネル状PCa壁2の上端部2bに下部が埋設固定されて上部が前記継手孔61に挿入された軸状継手材62と、この軸状継手材62の下部周囲に設けられた変形追従材63と、この変形追従材63と前記継手孔61の間に充填され固結した充填材64とで構成される。そして、これら継手孔61、軸状継手材62、変形追従材63、充填材64等の要素は、基本的には、先に説明した図3と同様のものである。
【0041】
支持部材7は、PCa手摺13上にパネル状PCa壁2の下端部2aの幅方向中央部を支持するものであって、PCa手摺13の上部に埋設されたアンカー71と、このアンカー71に軸心の周りに回転自在に取り付けられたボルト72と、パネル状PCa壁2の下端部2aに一体的に埋設され前記ボルト72に螺合された袋ナット73とからなり、基本的には、先に説明した図4と同様のものである。
【0042】
したがって、この形態においては、建物が地震力や風圧などによる水平荷重を受けることによって層間水平変位を生じた場合、バルコニー1と一体のPCa手摺13と、その上階のバルコニー1n+1の間で、パネル状PCa壁2が支持部材7を支点にして微小回転(ロッキング動作)され、第一及び第二のジョイント5,6における変形追従材53,63(図2,図3のゴムチューブ53a,63a)が、上下に相対変位する軸状継手材52,62と充填材54,64との間で剪断変形を受けることによって、バルコニー1,1n+1との間でパネル状PCa壁2が受ける強制変形が有効に吸収される。
【0043】
また、各バルコニー1及びパネル状PCa壁2の外側面に貼られた外壁タイル3は、各バルコニー1とパネル状PCa壁2との間の水平目地部、及びPCa手摺13とパネル状PCa壁2との間の水平目地部では、上下に互いに不連続であるため、上述したパネル状PCa壁2のロッキング動作によって前記水平目地部での外壁タイル3の破壊や剥離を生じるおそれはない。
【0044】
なお、本発明に係る建物の階層部と既製壁体との結合構造は、上述した各実施の形態以外にも、例えば建物外周に、各階層部毎に左右に互いに隣接して取り付けられるPCaあるいは鋼製のカーテンウォールや、建物内部のスラブと梁間に設置されるPCa間仕切り壁の結合部等にも適用することができる。
【0045】
【発明の効果】
請求項1の発明に係る建物の階層部と既製壁体との結合構造によれば、建物に地震力や風圧による層間水平変位を生じたときの既製壁体のロッキング動作に伴って、軸状継手材が継手孔に対して相対的に上下変位し、継手孔内周の充填材と、軸状継手材との間で変形を受ける変形追従材によって、既製壁体の受ける強制変形を吸収する構造であって、既製壁体の表面に露出する金具が不要であるため、外観上の美観を向上させることができ、錆の発生もなく、施工も容易であるので、施工コストを低減することができる。また、寸法誤差や施工誤差による継手孔と軸状継手材及び変形追従材との位置ずれを、充填材で埋めるため、ガタも発生しない。
【0046】
請求項2の発明に係る建物の階層部と既製壁体との結合構造によれば、既製壁体の重量による鉛直荷重を支持部材で受けるので、各ジョイントの変形追従材に余分な力が常時作用することがなく、建物に地震力や風圧による層間水平変位を生じたときに、既製壁体が前記支持部材を支点としてロッキング動作するので、各ジョイントの変形追従材による応力吸収効果を確実に奏することができる。
【0047】
請求項3の発明に係る建物の階層部と既製壁体との結合構造によれば、例えばバルコニーのPCa手摺などのような立上り壁と、その上階のバルコニーとの間に設けられる飾り柱などの既製壁体との結合部にも、有効に適用することができる。
【0048】
請求項4の発明に係る建物の階層部と既製壁体との結合構造によれば、変形追従材が、エラストマ材料からなるため、その剪断変形を利用して、既製壁体の微小回転時の既製壁体の受ける強制変形を有効に吸収することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a technique for connecting a ready-made wall body by a rocking construction method between each layer of a building.
[0002]
[Prior art]
In buildings, ready-made wall bodies such as decorative wall members (curtain walls) made of PCa (precast concrete) plates and internal partition walls made of PCa are connected to building layers such as balconies, frame outer peripheral beams, or beams. As a technology, a dry rocking construction method is known.

On the other hand, the joint hole 61 is formed corresponding to the coupling position with the shaft-like joint material 62 when the balcony 1 is constructed with cast-in-place concrete or precast concrete. A spiral tube 61a is provided on the peripheral surface. The spiral tube 61a is a cylindrical fitting fixed to the end of the reinforcing bar 12 when the balcony 1 is constructed. The spiral tube 61a is larger than the shaft-shaped joint material 62 for the purpose of absorbing dimensional errors and construction errors. It is formed with a sufficiently large diameter.
[0021]
Similarly to the deformation follower 53 of the first joint 5 described above, the deformation follower 63 is also extrapolated to the upper part 62b of the shaft joint 62 protruding from the upper end 2b of the panel PCa wall 2, for example, chloroprene. A rubber tube 63a made of rubber and a sponge 63b made of foam neoprene rubber provided on the upper inner periphery of the rubber tube 63a and disposed on the upper side of the shaft-like joint material 62 are configured. Further, the radial thickness of the rubber tube 63a is also appropriately set so that the maximum shear deformation amount due to the vertical displacement of the shaft-like joint material 62 accompanying the horizontal displacement described later is less than the allowable shear deformation amount. .
[0022]
The filler 64 is made of a resin-based or cement-based consolidated material such as mortar or grout, and the outer periphery of the spiral tube 61a of the joint hole 61 and the outer periphery of the shaft-like joint material 62 inserted in the inner periphery thereof.

Reference numeral 65 indicates that when the uncured filler 64 is filled, the filler 64 starts from the lower end of the joint hole 61 (spiral tube 61a) with the balcony 1 and the panel-like PCa wall 2 below it. The sponge is made of foamed neoprene rubber and is inserted into the horizontal joint so as to close the lower end opening of the joint hole 61 for the purpose of preventing the liquid from flowing into the gap (horizontal joint).
[0024]
The support member 7 supports the central portion in the width direction of the lower end 2a of the panel-like PCa wall 2 on the edge 1a of the balcony 1, and as shown in an enlarged view in FIG. The metal anchor 71 embedded in the upper portion of the edge 1a, the bolt 72 rotatably attached to the anchor 71 around the axis, and the lower end portion 2a of the panel-like PCa wall 2 are integrally embedded. It consists of a cap nut 73 screwed onto the bolt 72. The screw 72 and the cap nut 73 are screwed in order to adjust the level of the panel-like PCa wall 2. If level adjustment is not required, a support metal fitting may be simply provided. .
[0025]
2 to 4, reference numeral 4 is a sealing material interposed in a horizontal joint between the balcony 1 and the panel-like PCa wall 2, and 4 a is a backup material provided inside the sealing material 4. .
[0026]
According to the above-described configuration, the first joint 5, the second joint 6, and the support member 7 are configured such that the components are accommodated inside the horizontal joint between the balcony 1 and the panel-like PCa wall 2, and to the outside. There is no exposed part. For this reason, it fits well, the aesthetics of the appearance can be improved, and a finishing material for hiding the metal fittings as in the prior art is not required.
[0027]
In addition, many bolting operations for attaching a plurality of metal fittings and the like are eliminated at the time of construction, so that the cost can be reduced. Even if there is a positional shift between the joint holes 51 and 61 and the shaft-like joint materials 52 and 62 (deformation follow-up materials 53 and 63) due to dimensional errors and construction errors, the joint holes 51 and 61 and the deformation follow-up materials 53 and Since it is the structure which fills between 63 with the fillers 54 and 64, rattling like the conventional joint which consists of a some metal fitting does not generate | occur | produce.
[0028]
FIG. 5 is an explanatory diagram showing the locking operation of the panel-like PCa column due to the horizontal displacement in the coupling structure of this embodiment, and FIG. 6 shows the operations of the first and second joints accompanying the locking operation of the panel-like PCa column. It is explanatory drawing.
[0029]
That is, from the normal state shown in FIG. 5 (A), when the building receives a horizontal load due to seismic force, wind pressure, etc., the slab (balcony 1 n ) on the n floor as shown in FIG. 5 (B). On the other hand, when the n + 1 floor slab (balcony 1 n + 1 ) causes a relative horizontal displacement (interlayer horizontal displacement) in the direction indicated by the arrow F, the panel-like PCa wall is formed between both balconies 1 n and 1 n + 1. 2 n is slightly rotated (locked) with the support member 7 as a fulcrum. At this time, the joints a to d of the panel-like PCa wall 2 n formed by the pair of left and right first and second joints 5 and 6 are substantially vertically displaced when viewed locally.
[0030]
Specifically, in the interlayer horizontal displacement shown in FIG. 5 (B), the second joint 6 in the joint portion a has its shaft-like joint material 62 from the normal position shown in FIG. as shown in B), slightly displaced upward in the direction of reducing the gap G U between the panel-like PCa wall 2 n and balconies 1 n + 1 of the upper. Moreover, as for the 1st joint 5 in the coupling | bond part c of FIG.5 (B), as the shaft-shaped coupling material 52 is shown by FIG.6 (D) from the normal position shown by FIG.6 (C), the gap G L of the panel-shaped PCa wall 2 n and balcony 1 n of the lower side to the direction of expansion will be slightly displaced upward.
[0031]
On the other hand, although illustration is omitted, in the joint portion b of FIG. 5B, the shaft-like joint material 62 of the second joint 6 increases the gap between the panel-like PCa wall 2 n and the balcony 1 n + 1 on the upper side. In the coupling part d, the shaft-like joint material 52 of the first joint 5 is displaced downward so as to reduce the gap between the panel-like PCa wall 2 n and the balcony 1 n below it. It will be.
[0032]
For this reason, the rubber tubes 53a and 63a of the deformation followers 53 and 63 are subjected to deformation between the shaft-shaped joint materials 52 and 62 and the fillers 54 and 64, which are relatively displaced in the vertical direction, and the deformation is sheared. Since it is a direction, it becomes a low spring. Further, the sponges 53b and 63b of the deformation follow-up materials 53 and 63 are deformed in the compression direction, but since they are foams, their spring constants can be suppressed sufficiently low. Therefore, the forced deformation that the panel-like PCa wall 2 n receives between the balcony 1 n and 1 n + 1 is effectively absorbed by the flexible deformability of the deformation followers 53 and 63.
[0033]
In addition, since the outer wall tile 3 affixed to the outer surface of each balcony 1 and the panel-like PCa wall 2 is discontinuous with each other in the horizontal joint between each balcony 1 and the panel-like PCa wall 2, There is no possibility that the outer wall tile 3 is broken or peeled off at the horizontal joint portion by the locking operation of the panel-like PCa wall 2 described above.
[0034]
Further, in order to support the vertical load due to the weight of the panel-like PCa wall 2 via the support member 7 having a high rigidity, the rubber of the deformation follow-up materials 53 and 63 in the first and second joints 5 and 6 in a normal state. Excessive shear stress does not always act on the tubes 53a and 63a, and extra compressive or tensile stress does not always act on the sponges 53b and 63b. Therefore, it is possible to prevent the deformation following materials 53 and 63 from being deteriorated due to permanent distortion or the like.
[0035]

And the filler 54. The elements such as the joint hole 51, the shaft-like joint material 52, the deformation follow-up material 53, the filler 54, and the like are basically the same as those described above with reference to FIG.
[0040]
The lower part of the second joint 6 is embedded in the joint hole 61 formed at the joint between the edge of the balcony 1 and the PCa handrail 13 and the upper end 2b of the panel-like PCa wall 2 on the lower floor side of the balcony 1.
