【発明の属する技術分野】
本発明は、板ガラスで形成された板ガラス製柱部材と板ガラスで形成された板ガラス製梁部材との間を、力伝達部材を用いて接合する板ガラス製構造部材の接合構造に関する。
【０００２】
【従来の技術】
近年、構築物の構造部材として鋼材、コンクリート、木材以外の人工材料を用いる例が見られ、ガラス、合成樹脂からなる板材を板状構造部材として用いることが行われ始めている。殊に、最近は、透光性材料を用いた構築物が着目され、板ガラスからなる板状構造部材を用い、屋根、壁共に板ガラスで構成してある例が見られる。このような、板ガラスを板状構造部材とした従来の板状構造部材の接合構造においては、例えば板ガラスを板状体としてある例について説明すれば、図１９に示すように、板ガラスからなる板状柱部材１を立設し、同じく板ガラスからなる板状梁部材２を前記板状柱部材１に取り付けるのに、前記板状柱部材１の端部４と前記板状梁部材２の端部５との間を、相対回動を許容しない状態で剛接合していた。つまり、前記板状柱部材１或いは前記板状梁部材２に外嵌固定自在な板材からなる接合金物１２を前記夫々の端部４，５に外嵌固定し、前記夫々の接合金物１２と前記端部４，５とを、夫々に複数の挿通孔を貫通させ、夫々の挿通孔にボルト等の締結部材１６を挿通し、前記夫々の端部４，５に前記接合金物１２を複数箇所で、前記接合金物１２と前記板状柱部材１或いは前記板状梁部材２との間を接着して固定し、前記両接合金物１２同士を締結して、前記締結部材１６と前記接合金物１２とで前記板状柱部材１と前記板状梁部材２との接合部３における力伝達部材を形成していた。
【０００３】
【発明が解決しようとする課題】
上記従来構成においては、図１９に示した例においては、接合金物１２の一方の第一接合金物１２Ａの嵌合部１３を前記板状柱部材１の上端側の端部４に側方から被せ、複数の締結部材１６を前記板状柱部材１を板厚方向に貫通する挿通孔に挿通して前記板状柱部材１に固定して前記板状柱部材１の上端側の端部４に接合部３を形成し、前記接合金物１２の他方の第二接合金物１２Ｂの嵌合部１３を前記板状梁部材２の一端側の端部５に前記一端側から被せ、複数の締結部材１６を前記板状梁部材２を貫通する挿通孔に挿通して前記板状梁部材２に固定して前記板状梁部材２の一端側の端部５に接合部３を形成し、前記両接合金物１２Ａ，１２Ｂの連結部１４同士を、連結ブロック１５を挟んで締結部材１６を用いて連結する（図２０参照）ことで、前記板状梁部材２と前記板状柱部材１とを接合してあった。
【０００４】
このように、前記板状柱部材１と前記板状梁部材２とを剛接合してあったから、例えば前記板状梁部材２が面内における外力により面内変形を起こして撓む等の変位が生ずれば、両部材１，２の接合部３には、前記板状柱部材１の力学上の軸心と前記板状梁部材２の力学上の軸心とを含む面内における曲げ外力が作用するようになる。ところで、板状構造部材は面外方向の曲げに対しては弱く、このため、前記板状構造部材は、外力により作用する内部主応力が前記板状構造部材の厚み方向に対して直交する面内に作用するように極力配置されるのである。その結果、上記のように、板状柱部材１と板状梁部材２とを剛接合してあれば、前記厚み方向に直交する面内に関しては剛性に富む接合構造が得られるのである。
【０００５】
しかしながら、例えば従来、板状構造部材として用いられているガラス板材は、元来圧縮力に対する強度よりも張力に対する強度の方が弱いものであるから、僅かの歪みでも剪断歪みが生じて部分的に張力が作用すると、そこから破壊に至ることがあるので、前記接合部３には上述のように接合金物１２を用いて強固に接合していたのであるが、例えば地震の際などのように、前記板状柱部材１と前記板状梁部材２との間に大きな相対変位が生ずる条件下では、前記板状柱部材１は前記板状梁部材２の面内における曲げ外力が作用することを避けることは極めて困難である。このような面内曲げ外力が作用する構造体において、伸び歪みの許容量が小さい板ガラス部材からなる構造体の構造解析を行おうとすれば、不静定骨組み構造であるから、解析が困難で、解析精度が悪くなるために、安全係数を高くとる必要が生じ、その結果、接合部材６としての前記接合金物１２が大きくならざるを得ず、板ガラス部材を用いた構造体の特徴である透明感を阻害するようになる。
【０００６】
そこで本発明は、接合部における板ガラス製梁部材と板ガラス製柱部材との間の力伝達関係を簡単化して、経済設計を可能とすると共に、接合部材を小型化し、且つ、大きな相対角度変位を許容するようにした板ガラス製構造部材の接合構造を提供する点にある。
【０００７】
【課題を解決するための手段】
〔本発明の特徴構成〕
本発明に係わる板ガラス製構造体の接合構造の特徴構成は、板ガラス製柱部材と板ガラス製梁部材とを相対回動自在に接合してある点を基本的特徴とし、夫々下記の独特な特徴を備えるものである。
【０００８】
請求項１に係わる本発明の板ガラス製構造部材の接合構造の特徴構成は、板ガラス製柱部材と板ガラス製梁部材の面の方向を一致させて、板ガラス製柱部材の端部と板ガラス製梁部材の端部との間を、ピン部材を力伝達部材として、板ガラス製柱部材と板ガラス製梁部材の一致する面方向に沿って前記ピン部材周りに相対回動自在に接合してある（第１特徴構成）点にある。これを図４及び図５に示す例により説明すると、板ガラス製柱部材１と板ガラス製梁部材２の面の方向を一致させて、板ガラス製柱部材１の端部４と板ガラス製梁部材２の端部５との間を、ピン部材８を力伝達部材７として、板ガラス製柱部材１と板ガラス製梁部材２の一致する面方向に沿って前記ピン部材８周りに相対回動自在に接合してある。図示の例においては、前記板ガラス製柱部材１の上端側の端部４に力伝達部材７としてのピン部材８を回転自在に挿通するピン孔１０を設け、前記板ガラス製梁部材２の一端側の端部５に同じくピン孔１０を備える接合部材６を固定して、両者のピン孔１０にピン部材８を挿通して、両者を相対回動自在に接合してあるのである。
【０００９】
請求項２に係わる本発明の板ガラス製構造部材の接合構造の特徴構成は、上記第１特徴構成におけるピン部材を介して相対回動自在に連結してある一対の接合部材の一方を板ガラス製柱部材の端部に固着すると共に、他方の接合部材を、板ガラス製梁部材の端部に固着して、前記ピン部材を、前記板ガラス製柱部材及び前記板ガラス製梁部材の外側で、前記板ガラス製柱部材と前記板ガラス製梁部材との間に位置させてある（第２特徴構成）点にある。これを図１に示した例により説明すると、ピン部材８を介して相対回動自在に連結してある一対の接合部材６の一方、即ち第一接合部材６Ａを板ガラス製柱部材１の端部４に固着すると共に、前記接合部材６の他方、即ち第二接合部材６Ｂを、板ガラス製梁部材２の端部５に固着して、前記ピン部材８を、前記板ガラス製柱部材１及び前記板ガラス製梁部材２の外側で、前記板ガラス製柱部材１と前記板ガラス製梁部材２との間に位置させるのである。
【００１０】
請求項３に係わる本発明の板ガラス製構造部材の接合構造の特徴構成は、上記第１特徴構成又は第２特徴構成におけるピン部材を、板ガラス製柱部材の立設幅内に位置させてある（第３特徴構成）点にある。これを図４に示す例により説明すると、ピン部材８を、板ガラス製柱部材１の立設幅内に位置させてある。図示の例においては、力伝達部材７である前記ピン部材８を挿通するピン孔１０が前記板ガラス製柱部材１を貫通させて形成してあり、前記ピン部材８を前記板ガラス製柱部材１の立設幅内に位置させてあるのである。
【００１１】
請求項４に係わる本発明の板ガラス製構造部材の接合構造の特徴構成は、上記第３特徴構成における板ガラス製柱部材の力学上の軸心と前記板ガラス製梁部材の力学上の軸心とが同一面内に位置するように接合してある（第４特徴構成）点にある。これを図７及び図８に示した例により説明すると、ピン部材８を、板ガラス製柱部材１の立設幅内に位置させて、前記板ガラス製柱部材１の力学上の軸心Ｘ１と板ガラス製梁部材２の力学上の軸心Ｘ２とが同一面内に位置するように接合するのである。このために、図示の例においては、２枚の板ガラス製柱部材１を立設して、その上端側の端部４に、両板ガラス製柱部材１をその板厚方向に貫通するピン孔１０を形成し、板ガラス製梁部材２を前記両板ガラス製柱部材１の間に介装して、前記ピン孔１０と、前記板ガラス製梁部材２の端部５に設けたピン孔１０とにわたってピン部材８を挿通し、前記一対の板ガラス製柱部材１と前記板ガラス製梁部材２とを接合することで、前記一対の板ガラス製柱部材１の力学上の軸心Ｘ１と前記板ガラス製梁部材２の力学上の軸心Ｘ２とを交叉させて、両軸心Ｘ１，Ｘ２を同一平面内に位置させてある。
【００１２】
〔特徴構成の作用及び効果〕
板ガラス製構造部材である板ガラス製柱部材と板ガラス製梁部材とを相対回動自在な接合部材を用いて柔に接合することで、接合部における前記板ガラス製柱部材と板ガラス製梁部材との間の力伝達関係を簡単化して不静定次数を低くし、構造解析精度を高めて、経済設計を可能とすると共に、接合部材を極力小型化し、しかも、前記板ガラス製柱部材と前記板ガラス製梁部材との間の相対角度変位に対する許容度を高めることができるのである。夫々の特徴構成の奏する作用効果は、以下の通りである。
【００１３】
上記板ガラス製構造部材の接合構造の第１特徴構成によれば、板ガラス製柱部材に加わる面内の曲げ変形を軽減し、前記板ガラス製柱部材の曲げ応力による破壊を防止できるようになる。つまり、板ガラス製梁部材から板ガラス製柱部材に曲げモーメントを伝達することがなく、伝達される荷重を極力一軸応力関係に近付け得るから、前記板ガラス製柱部材に及ぼされる面内曲げ荷重を軽減して、前記柱部材や梁部材が脆い板ガラスで形成されていても、その脆い板ガラス製柱部材を破壊から保護できる。これを図４に示した例に沿って説明すれば、前記板ガラス製梁部材２の他端側の上下方向の変位があったにしても、前記板ガラス製梁部材２は前記ピン部材８の周りに回動するから、前記板ガラス製梁部材２の他端側の変位をモーメントとして前記板ガラス製柱部材１に伝達することを防止でき、図示の例においては特に、前記ピン部材８を介して前記板ガラス製柱部材１に直接力伝達を行うから、前記板ガラス製柱部材１への力伝達を一軸力伝達関係とすることが可能になる。
【００１４】
上記板ガラス製構造部材の接合構造の第２特徴構成によれば、板ガラス製柱部材の端部と板ガラス製梁部材の端部とに夫々接合部材を固着し、その接合部材同士を、ピン部材を力伝達部材として接合してあるから、前記板ガラス製柱部材及び前記板ガラス製梁部材には局所荷重を加えることなく、相対回動自在に接合でき、従って、前記板ガラス製柱部材に加わる曲げ外力を極力小さくできるのである。これを図１に示した例に沿って説明すれば、接合部材６における力伝達部材７であるピン部材８が板ガラス製柱部材１と板ガラス製梁部材２の間、即ち両部材１，２の外部に配置されているから、前記両部材１，２に対して、前記ピン部材８から前記板ガラス製柱部材１及び前記板ガラス製梁部材２に対して直接に点荷重を及ぼすことが回避可能になる。従って、接合部材６が関節構造を有していることから、前記板ガラス製梁部材２からの前記板ガラス製柱部材１への曲げ外力の作用を極力抑制しでき、前記板ガラス製柱部材１及び前記板ガラス製梁部材２の接合部３においては第一接合部材６Ａ及び第二接合部材６Ｂからなる接合部材６を前記両部材１，２に対して固着できて、前記両部材１，２内における面内曲げ歪みを抑制して、前記柱部材や梁部材が脆い板ガラスで形成されていても、その破壊を防止するのである。
【００１５】
上記板ガラス製構造部材の接合構造の第３特徴構成によれば、上記第１特徴構成又は第２特徴構成の作用効果を奏する中で、板ガラス製梁部材からの作用力を板ガラス製柱部材には軸力としてピン部材から伝達できるのである。これを図４に示した例に沿って説明すれば、ピン孔１０を板ガラス製柱部材１を貫通させて形成してあるから、板ガラス製梁部材２からの作用力はピン部材８から直接軸力として前記板ガラス製柱部材１に伝達されるようになるのである。また、前記板ガラス製梁部材２の長さ方向に前記板ガラス製柱部材１との間の相対変位が生じたりする場合には、前記ピン部材８から前記板ガラス製梁部材２に直接軸力として前記変位に伴う作用力が伝達されるようになるのである。
【００１６】
上記板ガラス製構造部材の接合構造の第４特徴構成によれば、上記第３特徴構成の作用効果を奏する中で、板ガラス製梁部材からの外力を板ガラス製柱部材に板を曲げる方向の力として作用させないようにでき、前記板ガラス製柱部材が折れることを防止できる。これを図７に示した例に沿って説明すれば、一対の前記板ガラス製柱部材１の合成柱としての力学上の軸心Ｘ１は、前記一対の板ガラス製柱部材１の間に位置するから、この間で板ガラス製梁部材２を軸支すれば、前記板ガラス製梁部材２の力学上の軸心Ｘ２が前記板ガラス製柱部材１の力学上の軸心Ｘ１と交叉するようになり、前記両軸心Ｘ１，Ｘ２が同一面内に位置することから、その面に対する面外応力が作用することを防止することが可能になる。従って、前記板ガラス製柱部材１に面外曲げ外力が作用することを抑制できるから、板ガラス製部材の特徴である面外曲げ外力に対する弱点を保護できて、前記柱部材１が圧縮強度に比して引っ張り強度の低いという特性を有する板ガラスで形成されていても、面外曲げ外力に伴う前記板ガラス製柱部材１の折損を防止できる。
【００１７】
尚、上記の本発明の課題を解決するための手段の説明において、図面を参照し、図面との対照を便利にするために符号を記したが、上記図面の参照及び符号の記入により本発明が参照図面他添付図面の構成に限定されるものではない。
【００１８】
【発明の実施の形態】
以下、本発明に係わる板ガラス製構造部材の接合構造について図面を参照しながら説明する。図１は本発明に係る板ガラス製柱部材と板ガラス製梁部材の接合部の一例を示す斜視図であり、図２はその上方より見た平断面図であり、図３は上記接合部を構築物に適用する例を示す側方視縦断面図である。尚、上記従来の技術の説明に用いた図１９及び図２０における要素と同一の要素乃至同様の機能を果たす要素については、先の図１９及び図２０に付した符号と同一の、或いは関連する符号を付し、詳細の説明の一部を省略する。
【００１９】
接合部材６は、図１に示すように、第一接合部材６Ａと第二接合部材６Ｂとからなり、両接合部材６Ａ，６Ｂ共に対をなして、夫々一端側に複数のボルト挿通用の挿通孔９を貫通してあり、前記第一接合部材６Ａの他端側には、力伝達部材７としてのピン部材８を回動自在に遊嵌可能なピン孔１０を、挟み付ける板ガラス製柱部材１の端部４の側端縁部に近接して形成し、前記第二接合部材６Ｂの他端側は、挟み付ける板ガラス製梁部材２の一端側の端部５の面間隔から前記第一接合部材６Ａの他端側同士の間に挿入可能に対向面を近接させて、同じく前記ピン部材８を回動自在に挿通可能なピン孔１０を前記板ガラス製梁部材２の一端側の端縁部に近接させて形成してある（図２参照）。尚、図示の例においては、前記板ガラス製柱部材１及び前記板ガラス製梁部材２の損傷を防止するために、前記板ガラス製柱部材１と前記第一接合金物６Ａとの間及び前記板ガラス製梁部材２と前記第二接合金物６Ｂとの間には間隙を設けてあり、その間隙を維持するために、夫々の間に緩衝材６ａを介装するが、エポキシ系接着剤や弾性系接着剤、エマルジョンラテックス系接着材等を用いて、前記板ガラス製柱部材１及び前記板ガラス製梁部材２に前記緩衝材６ａを接着し、或は、繊維材からなるシートで前記緩衝材６ａを形成して、上記接着材をこのシートに含浸して介装し、前記緩衝材６ａの介装後に前記板ガラス製柱部材１及び板ガラス製梁部材２に前記緩衝材６ａを接着させる。さらに、前記第一接合金物６Ａと前記第二接合金物６Ｂとの間にも間隙を設けて、相対回動を容易にしてある。
【００２０】
図２に示したように、前記両接合部材６Ａ，６Ｂは共に、前記板ガラス製柱部材１の端部４及び前記板ガラス製梁部材２の端部５を緩衝材６ａを介装して挟み付け、前記夫々の端部４，５に夫々複数貫通してある挿通孔９に緩衝材１７を外嵌したボルト等の締結部材１６を挿通して、前記夫々の端部４，５に固定される。前記夫々の端部４，５に固定された両接合部材６Ａ，６Ｂは、前記ピン孔１０に遊嵌されるピン部材８を力伝達部材７として接合されるのである。図示の例においては、前記板ガラス製柱部材１の上端側の端部４に第一接合部材６Ａを固定してあり、前記板ガラス製梁部材２の一端側の端部５に第二接合部材６Ｂを固定してある。尚、前記締結部材１６の頭部は、前記両接合部材６Ａ，６Ｂの外側に突出しないように、前記両接合部材６Ａ，６Ｂを座刳りして同一面になるようにしてある。
【００２１】
以上の構成により、前記板ガラス製柱部材１と前記板ガラス製梁部材２とは、前記ピン部材８を介して相対回動自在に接合してあるから、前記板ガラス製梁部材２の前記板ガラス製柱部材１に対する相対角度変位を生じても、両者が相対回動することで、前記板ガラス製柱部材１に面内の曲げモーメントを及ぼすことがなく、前記ピン部材８が前記板ガラス製柱部材１及び前記板ガラス製梁部材２を貫通していないので、力伝達部材７である前記ピン部材８が前記板ガラス製柱部材１及び前記板ガラス製梁部材２に集中荷重をもたらすことがなく、前記両部材１，２に多次元応力を生ずることを回避できて、一般に圧縮強度に比して引っ張り強度の低いという特性を有する板ガラスで形成された前記板ガラス製柱部材１及び前記板ガラス製梁部材２に損傷を招くことを抑制できる。また、接合部３の内の力を伝達する要部のみに接合部材６を取り付けて接合するから、その接合部材６は小型のものでよく、透視性を維持しながら接合できるから、美観を向上できる。
【００２２】
上記本発明に係る接合部３を構築物に設ける展望室に適用する例につき、図３を参照しながら説明する。板ガラス製柱部材１は外部構造体２５の上に取り付けられ、板ガラス製梁部材２は側部構造体の外部に張り出し形成した屋根張出部２３の外端部に取り付けられ、前記板ガラス製梁部材２と前記板ガラス製柱部材１とは、共に板ガラスで構成されて、本発明に係る接合部材６で接合される。前記外部構造体２５は、前記構築物に張り出し形成される展望室の腰壁であり、前記側部構造体は前記構築物の壁から外方に張り出し形成された屋根張出部２３である。前記板ガラス製柱部材１は前記外部構造体２５の上に取り付けられた枢支金物２０と、前記板ガラス製柱部材１の下端部に固定された接合金物１９との間で、ピン部材８を介して取り付ける。また、前記板ガラス製梁部材２は、前記屋根張出部２３の外端部に取り付けられた枢支金物２０と、前記板ガラス製梁部材２の他端部に固定された接合金物１９との間で、同様にピン部材８を介して取り付ける。これら接合金物１９と、前記板ガラス製柱部材１の下端部及び前記板ガラス製梁部材２の他端部との間にも、上述の接合部材６の取付と同様に、緩衝材を介装することが好ましい。
【００２３】
尚、前記板ガラス製梁部材２の一端側の端部５と前記板ガラス製柱部材１の上端側の端部４との間は、上述の接合部３と同様の構造で接合される。前記板ガラス製柱部材１の上端部と前記屋根張出部２３の上面との間には、前記板ガラス製柱部材１に対して揺動自在にサッシが取り付けられ、そのサッシの上に複層ガラスで形成された屋根パネル２１を取り付け、前記板ガラス製柱部材１の外側には、複層ガラスで形成された外壁パネル２２が取り付けられる。この構成により、前記展望室からの眺望に対して目障りになる接合部材６を極力小さくし、美観を高めながら、前記展望室の床部に連設された外部構造体２５と、前記展望室を張り出し形成した構築物の側部構造体との間に相対変位が生じても、前記板ガラス製柱部材１と前記板ガラス製梁部材２との間で相対角度変位を許容しているから、これら板ガラス製柱部材１及び板ガラス製梁部材２の損傷を抑制しつつ、前記屋根パネル２１及び前記外壁パネル２２の保持を維持できるようになる。
【００２４】
〔別実施形態〕
本発明の実施の形態について、上記実施の形態において説明した以外の実施形態につき、以下に説明する。
【００２５】
〈１〉上記実施の形態においては、接合部材６を、第一接合部材６Ａと第二接合部材６Ｂとで構成し、両接合部材６Ａ，６Ｂ共に対をなして、一端側に複数のボルト挿通用の挿通孔９を貫通して、板ガラス製柱部材１と板ガラス製梁部材２とに夫々固定し、前記両接合部材６Ａ，６Ｂの他端側にピン孔１０を形成して、前記両接合部材６Ａ，６Ｂのピン孔１０にピン部材８を挿通して、前記板ガラス製柱部材１と前記板ガラス製梁部材２とを相対回動自在に接合する例について説明したが、例えば図４に示すように、前記板ガラス製柱部材１の上端側の端部４に力伝達部材７としてのピン部材８を回転自在に挿通するピン孔１０を設け、前記板ガラス製梁部材２の一端側の端部５に同様のピン孔１０を備え、前記板ガラス製梁部材２の両面に接当自在な一対の接合部材６を固定し、両者のピン孔１０に緩衝材からなるブッシュ１１を外嵌したピン部材８を挿通して（図５参照）、両者を相対回動自在に接合してあってもよい。この場合には、前記ピン部材８は、前記板ガラス製柱部材１の立設幅内に位置させてあるのである（請求項３に対応）。
【００２６】
上記のような構成にあっては、前記板ガラス製梁部材２の他端側の上下方向の変位があったにしても、前記板ガラス製梁部材２は前記ピン部材８の周りに回動するから、前記板ガラス製梁部材２の他端側の変位をモーメントとして前記板ガラス製柱部材１に伝達することを防止でき、且つ、前記ピン部材８を介して前記板ガラス製柱部材１に直接力伝達を行うから、前記板ガラス製柱部材１への力伝達を一軸力伝達関係とすることが可能になる。しかも、前記ピン孔１０の下方には、前記板ガラス製柱部材１が荷重を受けるのに十分な長さを有しているから、前記板ガラス製梁部材２から伝達される荷重を分散して受けることができ、前記板ガラス製柱部材１を破損し難くするのである。さらに、前記ピン孔１０を前記板ガラス製柱部材１の力学上の軸心Ｘ１に位置させることができるから（図４参照）、前記板ガラス製梁部材２からの荷重は、前記板ガラス製柱部材１に軸力として伝達されるようになり、前記板ガラス製柱部材１に面内並びに面外の曲げ応力をもたらすことを回避できるのである。この場合においては、前記板ガラス製柱部材１と前記接合部材６との間には、相対回動を自在にするために、間隙を設けてあることが好ましく、この隙間は、１ｍｍ乃至数ｍｍとしてあればよい。尚、図４及び図５に示したように、前記両接合部材６を座刳りすることなく、前記締結部材１６の頭部は、前記両接合部材６の外側に突出させてある。
【００２７】
〈２〉上記実施の形態においては、接合部材６を、第一接合部材６Ａと第二接合部材６Ｂとで構成し、両接合部材６Ａ，６Ｂ共に対をなして、一端側に複数のボルト挿通用の挿通孔９を貫通して、板ガラス製柱部材１の上端側の端部４に、幅方向の２箇所に貫通された挿通孔９に締結部材１６を挿通して、第一接合部材６Ａを固定し、前記板ガラス製梁部材２の一端側の端部５には、長手方向の２箇所に貫通された挿通孔９に締結部材１６を挿通して第二接合部材６Ｂを固定し、前記両接合部材６Ａ，６Ｂの他端側にピン孔１０を形成して、前記両接合部材６Ａ，６Ｂのピン孔１０にピン部材８を挿通して、前記板ガラス製柱部材１と前記板ガラス製梁部材２とを相対回動自在に接合する例について説明したが、例えば図６に示すように、前記第一接合部材６Ａの一端側を幅広に形成し、その幅方向に並べて挿通孔を形成して締結部材１６により前記板ガラス製柱部材１の上端側の端部４に取り付け、前記一対の第一接合部材６Ａを夫々上方に延出して、上端部を貫通して前記ピン孔１０を設けてある。このような構成により、前記ピン部材８の位置を、前記板ガラス製柱部材１の力学上の軸心Ｘ１に位置させることができ、前記板ガラス製梁部材２からの荷重を、前記板ガラス製柱部材１への軸荷重として伝達できるようになる。
【００２８】
前記第一接合部材６Ａと前記板ガラス製柱部材１との間、及び前記第二接合部材６Ｂと前記板ガラス製梁部材２との間には、上述の接合部３と同様に緩衝材６ａを介装してあることが好ましい。尚、図示の例においては、上記実施の形態に示したとは逆に、前記第一接合部材６Ａの上端部の対向面の間を近接させて、前記第二接合部材６Ｂの他端側の間に介装し、前記ピン部材８で接合するようにしてある。また、図示の例においては、前記第一接合部材６Ａにおける挿通孔を、ピン孔１０への方向に対して直交する方向に配列したものを示したが、前記挿通孔の配置は任意であって、例えば複数列或いは任意の千鳥配列に配置してあってもよい。

〈３〉また、板ガラス製構造部材である板ガラス製柱部材１或いは板ガラス製梁部材に加わる荷重が大きい場合、或いは、天井部又は壁部からの前記板ガラス製構造部材の張出幅を大きくしたくない場合には、前記板ガラス製柱部材１或いは前記板ガラス製梁部材２を複数枚並設することで、前記張出幅を小さくする場合がある。このような場合には、例えば図７に示すように、前記板ガラス製柱部材１を２枚とすることもできる。上述の板ガラス製柱部材１の力学上の軸心Ｘ１上にピン部材を配置するのに、図８に示すように、２枚の板ガラス製柱部材１を立設して、その上端側の端部４に、両板ガラス製柱部材１を夫々の板厚方向に貫通するピン孔１０を形成し、板ガラス製梁部材２を前記両板ガラス製柱部材１の間に介装して、前記ピン孔１０と、前記板ガラス製梁部材２の端部５に設けたピン孔１０とにわたってピン部材８を挿通し、前記一対の板ガラス製柱部材１と前記板ガラス製梁部材２とを接合してもよい。この場合においても、前記ピン孔１０と前記ピン部材８との間には、緩衝材で形成した、前記ピン部材８を遊嵌可能なブッシュ１１を介装し、且つ、前記板ガラス製柱部材１と前記板ガラス製梁部材２との間にも上述の接合部３と同様に緩衝材６ａを介装しておく。
【００３０】
このようにすれば、前記一対の板ガラス製柱部材１の力学上の軸心Ｘ１と前記板ガラス製梁部材２の力学上の軸心Ｘ２とを交叉させて、両軸心Ｘ１，Ｘ２を同一平面内に位置させることができる。従って、一対の前記板ガラス製柱部材１の合成柱としての力学上の軸心Ｘ１は、前記一対の板ガラス製柱部材１の間に位置するから、この間に板ガラス製梁部材２を介装すれば、前記板ガラス製梁部材２の力学上の軸心Ｘ２が前記板ガラス製柱部材１の力学上の軸心Ｘ１と交叉するようになり、前記両軸心Ｘ１，Ｘ２が同一面内に位置することから、その面に対する面外応力の生成を防止することが可能になり、前記板ガラス製柱部材１を形成するガラス板に曲げ外力が作用することを抑制できるから、一般に圧縮強度に比して引っ張り強度の低いという特性を有する板ガラスからなる前記板ガラス製柱部材１の、曲げ外力に伴う損傷を防止できる。尚、前記緩衝材６ａは、前記板ガラス製柱部材１又は前記板ガラス製梁部材２に接着して、クリアランスを確保すると同時に、ガラスと金属の直接接触を防止し、且つ、相互の摺動性を維持できるようにする。さらに、この構成においては、接合部材６としては、ピン部材８と、前記板ガラス製柱部材１及び前記板ガラス製梁部材２のピン孔１０を保護する前記ブッシュ１１程度であるから、透明性を特徴とするガラス構造体において、接合部３に配置する接合部材６が小さくなり、美観をさらに向上できる。
【００３１】
〈４〉上記〈３〉の構成に代えて、例えば図９に示すように、板ガラス製柱部材１を１枚にし、板ガラス製梁部材２を対にして、前記板ガラス製柱部材１の上端側の端部４にピン孔１０を形成し、前記一対の板ガラス製梁部材２にも一端側の端部５に、共に貫通するピン孔１０を設けて、ピン部材８を、前記一対の板ガラス製梁部材２の間に前記板ガラス製柱部材１を介入させた状態で前記ピン孔１０に挿通し（図１０参照）、接合するようにしてもよい。もたらされる効果は上記〈３〉の構成におけると同様である。尚、例えば図１１に示すように、前記板ガラス製柱部材１をも対にして、前記対をなす板ガラス製梁部材２の間に前記板ガラス製柱部材１の対を介入させ、前記ピン部材８を貫通させて（図１２参照）接合してあってもよい。
【００３２】
ここでは、図１３に示したように、前記一対の板ガラス製柱部材１の間隔を保持する金属製の間隔保持部材１８を前記板ガラス製柱部材１の間に介装しておくとよい。また、前記間隔保持部材１８の外側には、前記ピン部材８を遊嵌自在なブッシュ１１を前記ピン孔１０に内挿しておけば前記ピン部材８と前記間隔保持部材１８との間で前記板ガラス製柱部材１及び前記板ガラス製梁部材２を挟み付けるのに、絞めすぎないようにでき、前記板ガラス製柱部材１及び前記板ガラス製梁部材２の位置決めができて、板ガラス製柱部材１及び板ガラス製梁部材２の損傷を防止できる。前記間隔保持部材１８と前記板ガラス製柱部材１との間、前記ピン部材８の頭部と前記板ガラス製梁部材２との間、及び前記板ガラス製柱部材１と前記板ガラス製梁部材２との間にも緩衝材６ａを介装し、前記板ガラス製柱部材１或いは前記板ガラス製梁部材２に接着しておけばよい。この構成によっても、上記〈３〉に示した例と同様に、前記対をなす板ガラス製梁部材２の力学上の軸心Ｘ２を前記対をなす板ガラス製柱部材１の力学上の軸心Ｘ１に交叉させることができる。尚、前記間隔保持部材１８を長さ方向の中央で分割し、間に第三の板ガラス製柱部材或いは第三の板ガラス製梁部材を狭持するように構成してあってもよい。
【００３３】
〈５〉また、先に図１に示した構成に代えて、例えば図１４に示すように、接合部材６を板ガラス製柱部材１に固定し、前記接合部材６と板ガラス製梁部材２との間をピン部材８を用いて止め付けるようにしてもよい。また、上記〈１〉で説明した板ガラス製柱部材１の立設幅内にピン部材８を配置するのに、例えば図１５に示すように、図４に示した構成の変形として、前記板ガラス製柱部材１の上端部４にピン孔を形成して、板ガラス製梁部材２の一端部５に下方に張り出して取り付けた接合部材６をピン部材８で接合するようにしてもよく、また、例えば図１６に示すように、前記板ガラス製柱部材１の上端部４に、上方に向けて固設した接合部材６に対して、前記板ガラス製梁部材２の一端部５に形成したピン孔との間でピン部材８を用いて接合するようにしてあってもよい。
【００３４】
〈６〉さらに、例えば図１７に示すように、対をなす板ガラス製柱部材１と板ガラス製梁部材２とを図７に示したと同様にして接合すると同時に、前記対をなす板ガラス製柱部材１の外側に沿わせて面方向の直交する第三の板ガラス製柱部材１Ａを立設して前記対をなす板ガラス製柱部材１に固定して断面コ字状の柱を構成し、前記第三の板ガラス製柱部材１Ａの上端側の端部４に、両端部にピン孔１０を形成した第三接合部材６Ｃを接合部材６として取り付け、横行板ガラス製梁部材２Ａを前記板ガラス製柱部材１の両側方にピン部材８を用いて接合するようにしてもよい。尚、この場合に、前記対をなす板ガラス製柱部材１と板ガラス製梁部材２との間に緩衝材からなる間隔保持材１８を介装してあればさらによい（図１８参照）。

BACKGROUND OF THE INVENTION
The present inventionSheet glassFormed withSheet glassWith column membersSheet glassFormed withSheet glassJoining beam members using force transmission membersSheet glassThe present invention relates to a joining structure of structural members.
[0002]
[Prior art]
In recent years, examples of using artificial materials other than steel, concrete, and wood as structural members of structures have been seen, and the use of plate materials made of glass and synthetic resin has begun to be used. In particular, recently, a construction using a translucent material has attracted attention, and there is an example in which a plate-like structural member made of plate glass is used and both a roof and a wall are made of plate glass. In such a joining structure of a conventional plate-like structural member using a plate glass as a plate-like structural member, for example, if an example where the plate glass is a plate-like body is described,FIG.As shown in FIG. 4, the plate-like column member 1 made of plate glass is erected, and the plate-like beam member 2 made of plate glass is attached to the plate-like column member 1 with the end 4 of the plate-like column member 1 and The end portion 5 of the plate beam member 2 is rigidly joined without allowing relative rotation. That is, the metal fittings 12 made of a plate material that can be fitted and fixed to the plate-like column member 1 or the plate-like beam member 2 are fitted and fixed to the end portions 4 and 5, respectively. Each of the end portions 4 and 5 is made to pass through a plurality of insertion holes, a fastening member 16 such as a bolt is inserted into each of the insertion holes, and the joint hardware 12 is inserted into each of the end portions 4 and 5 at a plurality of positions. The bonding hardware 12 and the plate-shaped column member 1 or the plate-shaped beam member 2 are bonded and fixed, and the bonding hardware 12 is fastened to each other, and the fastening member 16 and the bonding hardware 12 are The force transmission portion in the joint portion 3 between the plate-like column member 1 and the plate-like beam member 2MaterialWas forming.
[0003]
[Problems to be solved by the invention]
In the above conventional configuration,FIG.In the example shown in FIG. 4, the fitting part 13 of one first joining metal part 12A of the joining metal part 12 is placed on the end part 4 on the upper end side of the plate-like column member 1 from the side, and a plurality of fastening members 16 are disposed on the side. The plate-like column member 1 is inserted into an insertion hole penetrating in the plate thickness direction and fixed to the plate-like column member 1 to form a joint 3 at the end 4 on the upper end side of the plate-like column member 1, The fitting part 13 of the other second joining metal part 12B of the joining metal part 12 is put on the end part 5 on one end side of the plate-like beam member 2 from the one end side, and a plurality of fastening members 16 are placed on the plate-like beam member 2. The joint 3 is formed at the end 5 on one end side of the plate beam member 2 by being inserted into the penetrating insertion hole and fixed to the plate beam member 2, and the connecting portion 14 of the joint hardware 12A and 12B. They are connected to each other using a fastening member 16 with a connecting block 15 in between (FIG.Thus, the plate beam member 2 and the plate column member 1 are joined.
[0004]
As described above, since the plate-like column member 1 and the plate-like beam member 2 are rigidly joined, for example, the plate-like beam member 2 is displaced by in-plane deformation caused by an external force in the plane. Is generated, a bending external force in a plane including the mechanical axis of the plate-like column member 1 and the dynamic axis of the plate-like beam member 2 is applied to the joint portion 3 of both members 1 and 2. Comes to work. By the way, the plate-like structural member is weak against bending in the out-of-plane direction. Therefore, the plate-like structural member has a surface in which the internal principal stress acting by an external force is orthogonal to the thickness direction of the plate-like structural member. It is arranged as much as possible to act inside. As a result, if the plate-like column member 1 and the plate-like beam member 2 are rigidly joined as described above, a joining structure rich in rigidity can be obtained in the plane perpendicular to the thickness direction.
[0005]
However, for example, a glass plate material conventionally used as a plate-like structural member is inherently weaker in strength against tension than strength against compression force. When the tension acts, it may lead to breakage, so it was firmly joined to the joint 3 using the joint metal 12 as described above. For example, during an earthquake, Under the condition that a large relative displacement occurs between the plate-like column member 1 and the plate-like beam member 2, the plate-like column member 1 is subjected to bending external force in the plane of the plate-like beam member 2. It is extremely difficult to avoid. In such a structure in which an in-plane bending external force acts, if an attempt is made to perform a structural analysis of a structure made of a sheet glass member with a small allowable amount of elongation strain, the analysis is difficult because it is an indeterminate frame structure, Since the analysis accuracy is deteriorated, it is necessary to increase the safety factor. As a result, the metal joint 12 as the joining member 6 has to be large, and the transparency that is a characteristic of the structure using the plate glass member. Will be disturbed.
[0006]
Therefore, the present invention providesSheet glassWith beam membersSheet glassSimplified the force transmission relationship with the column member, enabling economic design, miniaturizing the joining member and allowing large relative angular displacementSheet glassIt is in providing a joint structure for structural members.
