【産業上の利用分野】
本発明は、上下に延びる空隙を挟んで隣接する２つの建物の各外壁間の相対的な変位を許容し、かつ空隙を塞ぐ構成の異なる２つの伸縮継手間にわたって設けられる伸縮継手装置の連結構造に関する。
【０００２】
【従来の技術】
図８は、典型的な従来技術の伸縮継手装置の連結構造を示す正面図である。間隔Ｌ０を有し、上下に延びる空隙２を挟んで隣接するたとえば建物の外壁である２つの躯体３，４間の空隙２を塞ぐために、構成の異なる第１伸縮継手５および第２伸縮継手６が設けられ、これらの第１および第２伸縮継手５，６間において露出する空隙２の露出部分２ａを塞ぐために継手装置１が設けられる。
【０００３】
各躯体３，４のうち図８において右方に配置される一方の躯体４は、各躯体３，４のうち図８において左方に配置される他方の躯体３の鉛直な一平面に沿って上下に延びる平坦状の外壁面３ａとほぼ同一平面上に形成される外壁面４ａと、この外壁面４ａよりも屋外７（図１０に図示）側、すなわち図８において、紙面に対して垂直手前側に突出する凸状外壁面４ｂとを有する。凸状外壁面４ｂに連なり、この凸状外壁面４ｂが形成され、前記外壁面３ａよりも屋外７側へ突出する凸状外壁部８の空隙２に臨み、空隙２を挟んで他方の躯体と対向する側壁面１２と、外壁面３ａとにわたって空隙２を塞ぐために第１伸縮継手５が設けられ、外壁面３ａと外壁面４ａとわたって空隙２を塞ぐために第２伸縮継手６が設けられる。
【０００４】
図９は図８の切断面線ＩＸ−ＩＸから見た断面図である。第１伸縮継手５は空隙２に沿って、すなわち図９の紙面に対し垂直な方向に沿って延びる第１カバープレート１０を有する。この第１カバープレート１０は、その幅方向、すなわち図９において左右方向の一端部が、ヒンジ１１によって側壁面１２に連結され、躯体４に対して角変位可能に連結される。また第１カバープレート１０の幅方向の他端部には、第１カバープレート１０の長手方向、すなわち図９の紙面に対して垂直な方向に延びるパッキン１３が、躯体３の外壁面３ａに臨んで設けられる。このような第１カバープレート１０を有する第１伸縮継手５は、一端部が躯体３に連結される引張コイルばね１４によって、屋外７から空隙２内に向け、したがって第１カバープレート１０の他端部を外壁部３ａに近接する方向に、すなわち当接させるようにばね付勢され、パッキン１３が躯体３に弾発的に当接するように構成される。
【０００５】
これによって、図９の矢符Ａで示す各躯体３，４が相互に近接／離反する方向である左右方向、および図９の矢符Ｂで示す屋外７から空隙２内へ、あるいは空隙２内から屋外７へ向かう前後方向の各躯体３，４の相対的な変位を許容して空隙２を塞ぎ屋外７から空隙２内へ雨水などが侵入することを防止している。図８および図９を参照して、第１伸縮継手５は幅Ｌ１を有し、たとえば各躯体３，４が左右方向Ａに相互に離反するように変位する場合、伸縮継手の幅Ｌ１と空隙２の幅Ｌ０との差Ｌ１−Ｌ０までの変位を許容することができる。
【０００６】
図１０は、図８の切断面線Ｘ−Ｘから見た断面図である。第２伸縮継手６は空隙２に沿って延びる第２カバープレート１６を有する。この第２カバープレート１６には、その幅方向、すなわち図１０において左右方向の両端部にパッキン１７，１８が、外壁面３ａおよび外壁面４ａに臨んでそれぞれ設けられる。このような第２カバープレート１６を有する第２伸縮継手６は、各躯体３，４にそれぞれ固定された縁材１９，２０によって変位可能に支持された状態で、パッキン１７，１８を外壁面３ａおよび外壁面４ａに弾発的にそれぞれ当接させ、引張コイルばね２１，２２によって屋外７から空隙２内に向け、したがって第２のカバープレート１６の両端部を各外壁面３ａ，４ａにそれぞれ近接させる方向に、すなわち当接するようにばね付勢される。
【０００７】
これによって、左右方向Ａおよび前後方向Ｂの各躯体３，４の相対的な変位を許容して空隙２を塞ぎ、屋外７から空隙２内への雨水などの侵入を防止している。
【０００８】
また、各引張コイルばね２１，２２の一端部は、第２伸縮継手６の幅方向のほぼ中央に連結され、各引張コイルばね２１，２２の他端部は、各躯体３，４にそれぞれ連結されている。これによって第２伸縮継手６は、その幅方向の中央位置を、常に空隙２の幅方向の中央位置を含む平面Ｓ内に配置することができる。図８および図１０を参照して、第２伸縮継手６は、幅Ｌ２を有し、たとえば各躯体３，４が相互に離反するように左右方向Ａに変位する場合、伸縮継手の幅Ｌ２と空隙２の幅Ｌ０との差Ｌ２−Ｌ０までの変位を許容することができる。
【０００９】
たとえば第１伸縮継手５の幅Ｌ１と第２伸縮継手６の幅Ｌ２とはほぼ同一に選ばれており、各躯体３，４の相対的な変位に対する各第１伸縮継手５，６の許容量が等しくなるように選ばれている。
【００１０】
このように構成される各第１伸縮継手５，６間において、露出する空隙２の一部２ａを塞ぐために用いられる継手装置１には、第３カバープレート２５が備えられる。この第３カバープレート２５は、高さＨ１を有し、かつ第１カバープレート１０の幅Ｌ１とほぼ等しい幅Ｌ３を有して第１カバープレート１０と意匠的に連続する上部２３と、高さＨ２を有し、かつ第２カバープレート１の幅Ｌ２とほぼ等しい幅Ｌ４を有して第２カバープレート１６と意匠的に連続する下部２４とを有する。これによって、第３カバープレート２５によって美観が損なわれることを防止している。継手装置１は、第３カバープレート２５の上部２３によって第１伸縮継手５の第１カバープレート１０を屋外から覆い、カバープレート２５の下部２４によって第２伸縮継手６の第２カバープレート１６を屋外から覆い、各第１カバープレート１０，１６のいずれか一方に取付けられて空隙２の一部分２ａを塞いでいる。
【００１１】
【発明が解決しようとする課題】
この従来の技術では、第３カバープレート２５は一体的に構成されており、第１伸縮継手５の第１カバープレート１０あるいは第２伸縮継手６の第２カバープレート１６に連結されている。たとえば第１伸縮継手５の第１カバープレート１０に取付けられ、各躯体３，４が左右方向Ａに相互に離反するように変位する場合において、各躯体３，４間の相対的な変位量が、下部２４が躯体３を覆っている幅Ｌ５以上に達すると空隙２ａが露出する。この幅Ｌ５は、第１伸縮継手５の許容量Ｌ１−Ｌ０より小さく、各躯体３，４間の相対的な変位の許容量が減少してしまう。また、各躯体３，４が前後方向Ｂに変位する場合、たとえば躯体４が躯体３に対し屋外７側へ変位する場合、第１カバープレート１０が、第２カバープレート１６に対して屋外７側へ変位してしまうので、カバープレート２５の下部２４と第２カバープレート１６との間に隙間を生じてしまう。逆に、躯体３が躯体４に対し屋外７側へ変位する場合、第２カバープレート１６が第１カバープレート１０に対して屋外７側へ変位してしまうので、第３カバープレート２５の下部２４が第２カバープレート１６に押付けられ、不所望な外力を受けて破損するおそれがある。
【００１２】
また継手装置１の第３カバープレート２５が第２伸縮継手６の第２カバープレート１６に取付けられ、各躯体３，４が左右方向Ａに相対的に近接するように変位する場合、前述のように第２伸縮継手６はその中央と空隙３の中央とを一致させるように構成されているため、カバープレート２５の上部２３が側壁面１２に押付けられ、不所望に外力を受けて破損するおそれがある。逆に各躯体３，４が相対的に離反するように変位する場合、上部２３と側壁面１２とが離間し、隙間が生じてしまう。また各躯体３，４が前後方向Ｂに相対的に変位する場合、たとえば躯体３が躯体４に対して屋外７側へ変位される場合、前述のような各第１カバープレート１０，１６間の相対的な位置関係から第３カバープレート２５の上部２３と第１カバープレート１０との間に隙間が生じてしまう。逆に、躯体４が躯体３に対して屋外７側へ変位する場合、前述のような各第１カバープレート１０，１６の相対的な位置関係から上部２３が第１カバープレート１０に押付けられ、不所望な外力を受けて破損するおそれがある。
【００１３】
したがって本発明の目的は、第１および第２カバープレートと同様に各躯体間の変位を許容し、各躯体間の相対的な変位によって破損したり、あるいは第１および第２カバープレートとの間で隙間を生じてしまうことを防止することができる伸縮継手装置の連結構造を提供することである。
【００１４】
【課題を解決するための手段】
本発明は、上下に延びる空隙を挟んで隣接する２つの躯体のうちいずれか一方の躯体は、他方の躯体の外壁面よりも屋外側へ突出する凸状外壁部を有し、この一方の躯体の凸状外壁部には、前記凸状外壁部の空隙に臨む側壁面から前記他方の躯体の外壁面にわたって延びる第１伸縮継手装置の第１カバープレートが角変位可能に設けられ、
各躯体には、第１カバープレートの延在方向に隣接して各躯体の外壁面間にわたって延びる第２伸縮継手装置の第２カバープレートが設けられ、
第１および第２伸縮継手装置間には、第１カバープレートとほぼ等しい幅を有し、第１カバープレートに連結される第１カバー体と、第２カバープレートとほぼ等しい幅を有し、第１カバー体に角変位可能に連結されるとともに第１カバー体に設けられるばね手段によって、前記空隙内に向けてばね付勢される第２カバー体とによって形成される第３カバープレートが設けられ、
第１および第２伸縮継手装置間を、第１および第２カバープレート間にわたって延びる第３カバープレートによって連結することを特徴とする伸縮継手装置の連結構造である。
【００１５】
【作用】
本発明に従えば、２つの躯体が上下に延びる空隙を挟んで隣接し、一方の躯体は、他方の躯体が有する上下に延びる平坦状の外壁面よりも屋外側へ突出する凸状外壁部を有する。一方の躯体の凸状外壁部には、その空隙に臨む外壁面から他方の躯体の外壁面にわたって第１伸縮継手装置の第１カバープレートが角変位可能に設けられて、各躯体間の変位を許容可能な状態で空隙が塞がれ、屋外から空隙内へ雨水などが侵入することを防止している。また、第１カバープレートの延在方向に隣接して、各躯体の外壁面間にわたって第２伸縮継手装置の第２カバープレートが設けられて、各躯体間の相対的な変位を許容可能な状態で空隙が塞がれ、屋外から空隙内へ雨水が侵入することを防止している。第１および第２カバープレート間には、第３カバープレートが設けられ、この第３カバープレートは、第１カバー体と第２カバー体とを有し、第１カバー体は第１カバープレートに連結され、第２カバー体は第１カバー体に角変位可能に連結され、かつ各外壁面に当接する方向にばね付勢される。これによって、第１および第２カバー体の相対的な変位を生じても、第３カバープレートが不所望な外力を受けることなしに各躯体の相対的な変位を許容し、かつ第１および第２伸縮継手装置間の隙間から屋外に露出する空隙を塞ぎ、屋外から空隙内に水が侵入することを防止することができる。また、第１カバー体は第１カバープレートとほぼ同一の幅を有し、第２カバー体は第２カバープレートとほぼ等しい幅を有する。これによって、意匠上の美観を損なうことなしに第１および第２伸縮継手間に第３カバープレートを配置して、空隙を塞ぐことができる。
【００１６】
【実施例】
図１は、本発明の一実施例の伸縮継手装置の連結構造を示す斜視図である。建物の外壁である２つの躯体３１，３２は、上下に延びる空隙３３を挟んで隣接して設けられる。図１において左方に配置される他方の躯体である躯体３１は、屋外に臨み、鉛直な一平面に沿って上下に延びる平坦状の外壁面３１ａを有する。右方に配置される一方の躯体である躯体３２は、他方の躯体３１の外壁面３１ａとほぼ同一平面を成して形成される外壁面３２ａと、この外壁面３２ａの上方で外壁面３１ａよりも屋外３４側、すなわち後述する図２において紙面に対し垂直手前側に突出する凸状外壁部３８に形成される凸状外壁面３２ｂとを有する。
【００１７】
このような各躯体３１，３２は、急激な地震あるいは地盤の不等沈下などによって、矢符Ｘで示す各躯体３１，３２が相互に近接／離反する方向である左右方向、あるいは矢符Ｙで示す屋外３４から空隙３３内へ、あるいは空隙３３内から屋外３４へ向かう方向である前後方向に相対的に変位するおそれがある。このような各躯体３１，３２間の相対的な変位を許容した状態で、屋外３４から空隙３３内に向けて雨水などが侵入することを防止する目的で、各躯体３１，３２間の空隙３３を塞ぐために第１伸縮継手３６および第２伸縮継手３７が設けられる。第１伸縮継手３６および第２伸縮継手３７は、それぞれに異なる構成を有し、第１伸縮継手３６は、凸状外壁部３８に外壁面３１ａと、凸状外壁面３２ｂに水平方向に連なり空隙３３に臨んで他方の躯体３１に対向する凸状外壁部３８の側壁面４６とにわたって延びて設けられ、第２伸縮継手３７は、第１伸縮継手３６の延在方向である下方に隣接し、外壁面３１ａと外壁面３２ａとの間にわたって延びて設けられる。これらの構成の異なる第１および第２伸縮継手３６，３７間にわたって空隙３３を塞ぐために本実施例の連結構造が実施される継手装置３０が設けられる。
【００１８】
図２は、本実施例の継手装置３０を示す正面図である。図１および図２を参照して、躯体３１，３２は、躯体３２が凸状外壁面３２ｂを有する凸状外壁部３８の領域においては間隔Ｌ１０をあけて離間し、外壁面３２ａを有する領域においては間隔Ｌ１１をあけて離間している。第１伸縮継手３６は、基本的に図９に示す第１伸縮継手５とほぼ同様の構成を有し、この第１伸縮継手３６には、アルミニウム合金から成る偏平な第１カバープレート４０が備えられる。この第１カバープレート４０の空隙３３に臨む側には、鋼鉄から成り、第１カバープレート４０の幅方向に延びる溝形鋼である補強部材４１が空隙３３の延びる方向、すなわち矢符Ｚで示される上下方向に相互に間隔をあけて複数設けられる。この補強部材４１の躯体３２寄りの端部には、鈎状に形成された係止部材４２がたとえば溶接によって固定される。第１カバープレート４０は、その幅方向の両端部が屋外３４から空隙３３内に向かう方向にほぼ直角に屈曲されており、この第１カバープレート４０の躯体３１寄りの端部には、たとえば合成樹脂などの弾発性を有する材料から成り、上下に延びるパッキン４３が設けられる。
【００１９】
また各躯体３１，３２には、鋼鉄から成る縁材４４，４５が、たとえばアンカーボルトなどによって固定され、上下に延びて設けられる。躯体３２に固定されている縁材４５は、凸状外壁面３２ｂに連なり、空隙３３に臨む側壁面４６に固定されており、この縁材４５には、係止部材４２と係合し合う係止部４５ａが形成されている。これによって第１伸縮継手３６が躯体３２に対して角変位可能に連結されて設けられる。また躯体３１に固定されている縁材４４には、たとえば引張コイルばね４７の一端部が連結され、この引張コイルばね４７の他端部は補強部材４１に連結されており、第１伸縮継手３６が、屋外３４から空隙３３内に向け、したがって第１カバープレート４０の他端部を外壁面３１ａに近接する方向に、すなわち当接するように弾発的に付勢される。これによって、第１伸縮継手３６がパッキン４３を躯体３１の外壁面３１ａに弾発的に当接させて設けられ、空隙３３を塞いで水密性が達成され、屋外３４から空隙３３内へ雨水などの侵入を防止している。また第１伸縮継手３６は躯体３１に対し左右方向Ｘに変位することができ、これによって各躯体３１，３２の相対的な左右方向Ｘおよび前後方向Ｙの変位を許容することができる。また躯体３２は縁材カバー４９が設けられており、これによって係止部材４２と縁材４５との間の係合部における水密性を向上している。
【００２０】
第１伸縮継手３６は、幅Ｌ１２を有しており、たとえば各躯体３１，３２が左右方向Ｘにおいて相互に離反するように変位する場合、第１伸縮継手３６の幅Ｌ１２と空隙３３の幅Ｌ１０の幅との差Ｌ１２−Ｌ１０に相当する変位量を許容することができる。
【００２１】
第２伸縮継手３７は、基本的に図１０に示す第２伸縮継手６とほぼ同様の構成を有し、この第２伸縮継手３７には、アルミニウム合金から成る偏平な第２カバープレート５０が備えられる。この第２カバープレート５０の幅方向、すなわち左右方向Ｘの両端部は屋外３４から空隙３３内に向かう方向にほぼ直角に屈曲されており、このような第２カバープレート５０の両端部には、たとえば合成樹脂などの弾発性を有する材料から成るパッキン５１が上下方向Ｚに延びて設けられる。このようなカバープレート５１の空隙３３に臨む側には、鋼鉄から成り、第２カバープレート５０の幅方向に延びる溝形鋼である図示しない補強部材が空隙３３の延びる方向に相互に間隔をあけて複数設けられている。
【００２２】
また各躯体３１，３２には、図示しない鋼鉄から成る縁材がそれぞれ固定されており、各縁材には図示しない引張コイルばねの一端部がそれぞれ連結されている。各引張コイルばねの他端部は、第２カバープレート５０に設けられた補強部材に第２カバープレート５０の幅方向の中央部において連結される。これによって、第２伸縮継手３７は、屋外３４から空隙３３内に向け、したがって第２カバープレート５０の両端部が各躯体３１，３２の外壁面３１ａ，３２ａにそれぞれ近接する方向に、すなわち当接するように弾発的に付勢され、前記縁材に支持された状態でパッキン５１を躯体３１の外壁面３１ａおよび躯体３２の外壁面３２ａに弾発的に当接して空隙３３を塞ぎ、水密性を達成して雨水などの侵入を防止している。また第２伸縮継手３７は、その幅方向中央部が各躯体３１，３２に向けてそれぞれ引張付勢されるので、第２伸縮継手３７は、その幅方向の中央と空隙３３の中央とをほぼ一致させた状態で空隙３３を塞ぐことができる。これによって、各躯体３１，３２の左右方向Ｘおよび前後方向Ｙの相対的な変位を許容し、第２伸縮継手３７の幅Ｌ１３を有効的に利用して、たとえば躯体３１，３２が左右方向Ｘに関し相互に離反するように変位される場合、第２伸縮継手３７の幅Ｌ１３と空隙３３の幅Ｌ１１との差Ｌ１３−Ｌ１１に相当する変位量を許容して空隙３３を塞ぐことができる。
【００２３】
継手装置３０は、第３カバープレート１３０を備え、この第３カバープレート１３０は、第１伸縮継手３６の第１カバープレート４０とほぼ同一の幅を有する第１カバー体５２と、第２伸縮継手３７の第２カバープレート５０とほぼ同一の幅を有する第２カバー体５３によって形成される。継手装置３０は、さらに第１カバー体５１に第２カバー体５３を角変位可能に連結するヒンジ５４と、第２カバー体５３を、空隙３３を塞ぐ方向、したがって屋外３４から空隙３３内に向かう方向、つまり第２カバープレート体を各躯体３１，３２の外壁面３１ａ，３２ｂに近接する方向に、すなわち当接するようにばね付勢する引張りコイルばね６４とを含んで構成される。
【００２４】
図３は図２の切断面線ＩＩＩ−ＩＩＩから見た断面図である。図２および図３を参照して、第１カバー体５２は、アルミニウム合金から成る偏平な部材であり、躯体３１，３２間にわたって延びて設けられる。この第１カバー体５２の躯体３１寄り、すなわち図２の左方寄りの端部には、下方に延出する延出部５５が形成される。このカバー体５２は、その上部５２ａによって、第１伸縮継手３６に備えられる第１カバープレート４０の下端部４０ａを屋外３４側から覆うように配置されて、たとえばビス５６によって第１カバープレート４０に固定される。第１伸縮継手３６の第１カバープレート４０と第１カバー体５２との隙間には、ブチルテープが貼付けられており、これによって水密性が達成されている。この第１カバー体５２の下端部には、たとえば合成樹脂などの弾発性を有する材料から成るパッキン５７が第１カバー体の長手方向すなわち図２の左右方向に延びて設けられる。また第１カバー体の下端部躯体３２寄りの端部付近には、ばねを取付けるためのばね取付体５８が空隙３３内に向けて突出して設けられる。このような第１カバー体５２は、前述のようにビス５６によって第１伸縮継手３６に固定されることによって、第１伸縮継手３６と同様に躯体３２に対し角変位可能であり、躯体３１寄りの端部が躯体３１の外壁面３１ａに向けて付勢される。
【００２５】
第２カバー体５３は、アルミニウム合金なら成り、躯体３１，３２間にわたって延びて設けられる。この第２カバー体５３は、左右方向Ｘおよび上下方向Ｚに延びる仮想平面と平行に配置される基部５９と、この基部５９の上端部に連なりほぼ直角に屋外３４から空隙３３内に向かう方向に屈曲する上側部６０と基部５９の下端部に連なりほぼ直角に屋外３４から空隙３３内に向かう方向に屈曲する下側部６１とを含み、前後方向Ｙに延びる鉛直な仮想平面における断面形状が大略的にＵ字状に形成される。このような第２カバー体５３は、躯体３１寄りの端部、すなわち図２の左方側の端部がヒンジ５４によって第１カバー体５２の延出部５５に連結される。これによって第２カバー体５３は、第１カバー体５２に対し鉛直な軸線まわりに角変位可能に設けられる。
【００２６】
また第２カバー体５３には、第１カバー体５２に取付けられた取付体５８に臨む位置付近に、上側部６０から下側部６１にわたって板状のばね取付部材６２が固定される。このばね取付部材６２には、係止孔６３が形成され、この係止孔６３に一端部が挿入されて引張コイルばね６４が係止される。また第２カバー体５２に取付けられたばね取付体５８の先端部には、たとえばボルトなどによって実現される係止片６５が固定されており、この係止片に引張コイルばね６４の他端部が係止される。これによって、第２カバー体５３は、屋外３４から空隙３３内に向けて、すなわち第２カバー体５３の両端部を各躯体３１，３２の外壁面３１ａ，３２ａにそれぞれ近接する方向に、すなわち当接するように弾発的に付勢される。
【００２７】
第１カバー体５２と第２カバー体５３との間は第１カバー体５２に取付けられたパッキン５７が第２カバー体の上側部６０に弾発的に当接されて水密性が達成されている。また第２カバー体５３と第２伸縮継手３７との間に関しては、第２伸縮継手３７に、たとえば合成樹脂から成る弾発性を有するパッキン６６が固定されており、このパッキン６６が弾発的に第２カバー体５３の下側部６１に当接され水密性が達成されている。
【００２８】
図４は図３の切断面線ＩＶ−ＩＶから見た断面図である。第２カバー体５３は、基部５９、上側部６０および下側部６１に加えて、さらに基部５９の左端部に連なり屋外３４から空隙３３内に向かう方向にほぼ直角に屈曲して設けられる左側部７３と基部５９の右端部に連なり屋外３４から空隙３３内に向かう方向にほぼ直角に屈曲する右側部７４とを含む。左側部７３は、基部５９の左端部に連なり外壁面３１ａに近接するにつれて左方に傾斜して設けられる傾斜部８１と、この傾斜部８１の外壁面３１ａに近接する端部に連なり屋外３５から空隙３３内に向かう方向に屈曲する屈曲部８２と、この屈曲部８２の外壁面３１ａに近接する端部から右方向、すなわち図５の右方向につれて突出する凸部８３とを有する。
【００２９】
このように左側部７３に傾斜部８１を設けることによって、第２カバー体５３が、ヒンジ５４を介し第１カバー体５２に対し角変位されるときに、第１および第２カバー体５２，５３が相互に干渉してしまうことを防止し、相互に角変位することができるように構成されている。
【００３０】
右側部７４は、基部５９の右端部に連なり屋外３４から空隙３３内に向かう方向にほぼ直角に屈曲する屈曲部８４と、この屈曲部８４の外壁面３２ａに近接する端部に連なり、ほぼ直角に左方、すなわち図５の左方向に屈曲して突出する突部８５とを有する。
【００３１】
第１カバー体５２の延出部５５の右端部には、屋外３４から空隙３３内に向かう方向に突出し、その先端から右方向に屈曲するヒンジ取付片７５がたとえばビスなどによって取付けられる。ヒンジ５４は、鉛直方向に延びて配置されるヒンジピン７７によって、一対のヒンジ片７８，７９が鉛直な軸線まわりに相互に角変位できるように構成されている。このようなヒンジ５４の一方のヒンジ片７８は、たとえばビスなどによってヒンジ取付片７５に固定され、他方のヒンジ片７９は第２カバー体５３の左側部７３にたとえばビスなどによって固定される。これによって、第１カバー体５２と第２カバー体５３とが鉛直な軸線まわりに相互に角変位することができる。また、延出部５５の右端部にはたとえば合成樹脂などの弾発性を有する材料から成るパッキン７６が設けられており、このパッキン７６は、左側部７３に弾発的に当接しており、第２カバー体５３が第１カバー体５２に対し角変位しても、パッキン７６は弾発的に左側部７３に当接し、これによって水密性が達成される。また第２カバー体５３の右側部７４には、基準外壁部３９に臨んでたとえば合成樹脂などの可撓性および弾発的を有する材料から成るパッキン８０が設けられ、このパッキン８０が弾発的に外壁面３２ａに当接されて水密性が達成される。

また第２カバー体５３は、基部５９を第１カバー体５２および第２伸縮継手３７の第２カバープレート５０よりも屋外３４側に突出した位置に配置し、この基部５９に連ねて、上側部６０、下側部６１、左側部７３および右側部７４を屋外から空隙３３内に向かう方向に屈曲させて設けて、これによって第１カバー体５２および第２伸縮継手３７よりも屋外３４側に突出して設けられる。したがって、第２カバー体５３が前後方向Ｙに充分な幅を有するので、各躯体３１，３２の相対的な変位によって第１および第２カバー体５２，５３が相対的に角変位されたときに、第１カバー体５２と第２カバー体５３あるいは第２カバー体５３と第２伸縮継手３７とが相互に離間してしまい、隙間が生じて水密性が損なわれることを防止することができる。すなわち第２カバー体５３が第１カバー体５２に対して角変位されても、前述のようにパッキン５７，６６，７０，７６，８０が弾発的に当接された状態が維持されて、水密性が達成された状態が維持される。
【００３３】
ばね取付体５８は、台形状であり、先端に向かうにつれて幅が小さくなるように形成される基部６７と、この基部６７の幅方向両端部から上方、すなわち図４の紙面に対し垂直手前側に立上がる立上り部６８，６９とを含み、これによって前述の引張コイルばね６４による曲げ、すなわち先端部および後端部に対し先端部および後端部間の中間部が上に凸となるようなばね取付体５８が受ける外力に対し、効率良く抗して、ばね取付体５８の形状を維持するように構成されている。これによって、ばね取付体５８を小形化および軽量化して、かつばね取付体５８の変形を防止して、第２カバー体５３に対する弾発的な付勢が弱まることを防止することができる。
【００３４】
第２カバー体５３の右方の端部付近の上側部６０には、その外周に沿ってたとえば合成樹脂などの弾発性を有する材料から成るパッキン７０が設けられる。このパッキン７０は凸状外壁面３２ｂに連なる下面３８ａ（図３に図示）に弾発的に当接し、これによって水密性が達成されている。また縁材カバー４９には、側壁面４６に臨むパッキン７１と、第１伸縮継手３６に備えられる第１カバープレート４０に臨むパッキン７２が設けられ、これらのパッキン７１，７２は、ともにたとえば合成樹脂などの弾発性を有する材料から成り、上下方向Ｚに延びて設けられ、側壁面４６および第１カバープレート４０にそれぞれ弾発的に当接されて水密性が向上されている。
【００３５】
また躯体３１，３２間にわたって、たとえば合成ゴムなどから成る止水板８８が縁材４４，４５によって取付けられて、上下方向Ｚに延びて設けられる。これによって水密性がさらに向上され、また屋外３４と空隙３３内とを温度差による結露などを防止することができる。
【００３６】
さらに躯体３１，３２間にわたってたとえば石綿などによって実現される耐火材から成る耐火体８９が上下方向Ｚに延びて設けられる。これによって、火災時に屋外３４から空隙３３内あるいは空隙３３内から屋外３４に炎や煙などを伴った熱気などが出入りすることを防止することができる。

図５は本発明の他の実施例の伸縮継手装置の連結構造を示す斜視図である。２つの躯体１０１，１０２は、上下に延びる空隙１０３を挟んで、間隔Ｌ２０をあけて離間し、隣接している。図５において左方に配置される他方の躯体である躯体１０１は、鉛直な一平面に沿って延びる平坦な外壁面１０１ａを有する。図５において右方に配置される一方の躯体である躯体１０２は、躯体１０１の外壁面１０１ａよりも僅かに屋外１０４側に、すなわち図６の右方向に突出しほぼ同一平面を成して形成される外壁面１０２ａと、外壁面１０２ａの上方で、外壁面１０１ａよりも屋外１０４側に突出する凸状外壁部１０５に形成される凸状外壁面１０２ｂとを有する。
【００３８】
この各躯体１０１，１０２間の前述したような相対的な変位を許容した状態で、屋外１０４から空隙１０３内に雨水などが侵入することを防止する目的で、空隙１０３を塞ぐために第１伸縮継手１０６および第２伸縮継手１０７が設けられる。第１伸縮継手１０６は、前述した第１伸縮継手３６と同様の構成を有するので、同一の参照符号を付し重複を避けて説明は省略する。
【００３９】
第２伸縮継手１０７は前述した第２伸縮継手３７とほぼ同様の構成を有している。本実施例において外壁面１０２ａは、前述のように躯体１０１の外壁面１０１ａよりも僅かに屋外１０４側に突出している。第２伸縮継手１０７は、外壁面１０１ａと外壁面１０２ａとにわたって空隙１０３を塞ぐ目的で設けられるため、躯体１０１に臨む左側の厚みよりも、躯体１０２に臨む右側の厚みが小さく選ばれている。これによって第２伸縮継手１０７に備えられる第２カバープレート１０９を、各躯体１０１，１０２の外壁面１０１ａ，１０２ａ，１０２ｂおよび第１伸縮継手１０６の第１カバープレート４０と平行を成して設けることができる。したがって意匠上の美観を損なうことなしに各第１伸縮継手１０６および第２伸縮継手１０７を設けることができる。その他の第２伸縮継手１０７の構成については、前述の第２伸縮継手３７と同様の構成を有するので重複を避けて説明は省略する。これらの第１および第２伸縮継手１０６，１０７間にわたって空隙１０３を塞ぐために本実施例の連結構造が実施される継手装置１００が設けられる。

図６は躯体１０１から躯体１０２を見た状態で鉛直な断面を示し、後述する図７の切断面線ＶＩ−ＶＩから見た断面図であり、図７は図６の切断面線ＶＩＩ−ＶＩＩから見た断面図である。図５〜図７を参照して、継手装置１００は、第３カバープレート１０８を備え、この第３カバープレート１０８は、第１伸縮継手１０６とほぼ同一の幅を有する第１カバー体１１０と、第２伸縮継手１０７とほぼ同一の幅を有する第２カバー体１１１とを有する。継手装置１００は、さらに第１および第２カバー体１１０，１１１を相対的に角変位可能に連結するヒンジ５４と、第２カバー体１１０を空隙を塞ぐ方向である屋外１０４から空隙１０３内に向けて、したがって第２カバー体１１０を各躯体１０１，１０２の外壁面１０１ａ，１０２ａに近接する方向、すなわち当接するようにばね付勢する引張りコイルばね６４とを含んで構成される。第１カバー体は、第１伸縮継手１０６に備えられる第１カバープレート４０の下端部４０ａを屋外１０４側から覆い、ビス５６によって固定される上部１１３と、上部１１３の下端部に連なり屋外１０４に向けて屈曲し、空隙１０３内から屋外１０４に向かうにつれて下方に傾斜する傾斜部１１４と、この傾斜部１１４の屋外１０４寄りの端部に連なり鉛直下方に向けて屈曲する下部１１５とを有する。このようにして下部１１５と第２カバー体１１１の基部５９とを同一平面上に配置している。本実施例において、躯体１０２の外壁面１０２ａは、躯体１０１の外壁面１０１ａよりも屋外１０４側に突出している。これによって、第２伸縮継手１０７の第２カバープレート１０９は、第１伸縮継手１０６に備えられる第１カバープレート４０よりも屋外１０４側に突出した位置に配置されることになる。
【００４１】
このように第１カバー体１１０に傾斜部１１４を設け、下部１１５を屋外１０４側に突出させて形成することによって、下部１１５と第２カバー体の基部５９と第２伸縮継手１０７の第２カバープレート１０９とをほぼ同一の平面内に配置することができ、意匠的に連続させて美観を向上することができる。またこのように第１カバー体と下部１１５と第２カバー体１１１の基部５９とをほぼ同一の平面内に配置することによって、第１カバー体１１５と第２カバー体１１１とが相対的に角変位される際に、第１および第２カバー体１１０，１１１が相互に干渉し合うことを防止することができ、これによって第２カバー体１１１の左側部１１６には図１〜図４に示した実施例のように傾斜部８１を設ける必要がない。その他の図１〜図４に示す実施例と同様の構成を有する部分には同一の参照符号を付し、説明は省略する。
【００４２】
このように本発明に従う連結構造が実施される継手装置１００は、一方の躯体１０２の外壁面１０２ａが、他方の躯体１０１の外壁面１０１ａよりも屋外に突出して形成されるような各躯体１０１，１０２間の空隙１０３を塞ぐために好適に実施することができる。
【００４３】
勿論本発明の他の実施例として他方の躯体１０１の外壁面１０１ａが一方の躯体１０２の外壁面１０２ａよりもわずかに屋外１０４側に配置された状態で、隣接する各躯体１０１，１０２間の空隙１０３を塞ぐためにも好適に実施することができる。すなわち本発明に従う伸縮継手装置の連結構造は、一方の躯体の外壁面が他方の躯体の外壁面とほぼ同一平面を成して形成される２つの躯体間の空隙に、好適に実施することができる。
【００４４】
また上述の実施例において第１カバー体５２，１１０と第２カバー体５３，１１１とは、ヒンジ５４によって連結されて相対的に角変位可能に設けられ、かつ引張コイルばね６４を用いて第２カバー体５３，１１１を屋外から空隙に向けて弾発的に付勢するように構成されたけれども、本発明の他の実施例として、ヒンジ５４に代えて板ばねを用いて連結し、この板ばねによって第１および第２カバー体を相対的に角変位可能に設けて、かつこの板ばねによって第２カバー体を屋外から空隙内に向けて弾発的に付勢するようにしてもよい。またさらに他の実施例としてヒンジ５４に代えて板ばねを用いて連結し、かつ引張コイルばね６４を用いて第２カバー体を屋外から空隙内に向けて弾発的に付勢するようにしてもよい。
【００４５】
【発明の効果】
以上のように本発明によれば、２つの躯体が空隙を挟んで隣接し、第１カバープレートが、一方の躯体の凸状外壁部の側壁面に角変位可能に設けられ、第２カバープレートが各躯体の外壁面間にわたって設けられる。これらの第１および第２伸縮継手装置間にわたって継手装置の第３カバープレートが設けられる。この第３カバープレートの第１カバー体は第１カバープレートに連結され、第２カバー体は第１カバー体に対して角変位可能に連結され、空隙内に向けてばね付勢される。これによって、各躯体が相対的に変位しても各カバー体が角変位されることによって、不所望な外力を受けることを防止して、継手装置などが破損することを防止することができ、かつ異なる構成の第１および第２伸縮継手装置間の隙間から露出する空隙を塞ぎ、水密性を達成することができるので、前述のようなたとえば凸状外壁面を有する躯体と、その躯体に隣接する躯体との間に挟まれる空隙を各躯体の相対的な変位を許容した状態で塞いで屋外から空隙内への雨水などの侵入を防止することができる。
【００４６】
また、第１カバー体は第１カバープレートとほぼ等しい幅を有し、第２カバー体は第２カバープレートとほぼ等しい幅を有し、これによって２つの構成の異なる第１および第２伸縮継手装置を意匠的に連続させて空隙を塞ぐことができるので、美観を損なうことなしに空隙を塞ぐことができる。

[Industrial applications]
The present invention relates to a coupling structure of an expansion joint device provided between two expansion joints having different configurations that allow relative displacement between outer walls of two buildings adjacent to each other with a vertically extending gap therebetween and that close the gap. About.
[0002]
[Prior art]
FIG. 8 is a front view showing a connection structure of a typical prior art expansion joint device. A first expansion joint 5 and a second expansion joint 6 having different configurations to close a gap 2 between two frames 3 and 4 which are adjacent to each other with a gap L0 and extend vertically, for example, which are outer walls of a building. Is provided, and a joint device 1 is provided to close an exposed portion 2a of the gap 2 exposed between the first and second expansion joints 5 and 6.
[0003]
One of the skeletons 4 arranged to the right in FIG. 8 among the skeletons 3 and 4 is arranged along one vertical plane of the other skeleton 3 arranged to the left in FIG. An outer wall surface 4a formed substantially on the same plane as a flat outer wall surface 3a extending vertically, and an outdoor 7 (shown in FIG. 10) side of the outer wall surface 4a, that is, in FIG. And a convex outer wall surface 4b protruding to the side. The convex outer wall surface 4b is continuous with the convex outer wall surface 4b. The convex outer wall surface 4b is formed. The convex outer wall surface 4b faces the gap 2 of the convex outer wall portion 8 protruding outside 7 from the outer wall surface 3a. A first expansion joint 5 is provided to cover the gap 2 over the opposing side wall surface 12 and the outer wall surface 3a, and a second expansion joint 6 is provided to cover the gap 2 across the outer wall surface 3a and the outer wall surface 4a.
[0004]
FIG. 9 is a cross-sectional view taken along line IX-IX of FIG. The first expansion joint 5 has a first cover plate 10 extending along the gap 2, that is, along a direction perpendicular to the plane of FIG. 9. The first cover plate 10 has one end in the width direction, that is, the left and right direction in FIG. 9, connected to the side wall surface 12 by the hinge 11, and is connected to the frame 4 so as to be angularly displaceable. At the other end of the first cover plate 10 in the width direction, a packing 13 extending in the longitudinal direction of the first cover plate 10, that is, the direction perpendicular to the paper surface of FIG. 9 faces the outer wall surface 3 a of the frame 3. Is provided. The first expansion joint 5 having such a first cover plate 10 is directed from the outside 7 into the gap 2 by the extension coil spring 14 having one end connected to the frame 3, and therefore, the other end of the first cover plate 10. The portion is spring-biased in a direction approaching the outer wall portion 3 a, that is, is brought into contact with the outer wall portion 3 a, and the packing 13 is configured to resiliently contact the frame 3.
[0005]
Thereby, the left and right directions in which the frames 3 and 4 indicated by the arrow A in FIG. 9 approach / separate from each other, and the outside 7 indicated by the arrow B in FIG. The gap 2 is closed by permitting relative displacement of each of the frames 3 and 4 in the front-rear direction from the outside to the outside 7 to prevent rainwater or the like from entering the inside of the gap 2 from the outside 7. 8 and 9, the first expansion joint 5 has a width L1. For example, when each of the skeletons 3 and 4 is displaced so as to separate from each other in the left-right direction A, the width L1 of the expansion joint and the gap are set. The displacement up to the difference L1−L0 from the width L0 of 2 can be allowed.
[0006]
FIG. 10 is a cross-sectional view taken along line XX of FIG. 8. The second expansion joint 6 has a second cover plate 16 extending along the gap 2. The second cover plate 16 is provided with packings 17 and 18 at both ends in the width direction, that is, both left and right directions in FIG. 10, facing the outer wall surface 3a and the outer wall surface 4a, respectively. The second expansion joint 6 having such a second cover plate 16 displaces the packings 17, 18 with the outer wall surfaces 3a in a state where the packings 17, 18 are displaceably supported by edge members 19, 20 fixed to the respective frame members 3, 4. And elastically abut against the outer wall surfaces 4a, respectively, and are directed from the outdoors 7 into the air gap 2 by the extension coil springs 21 and 22, so that both ends of the second cover plate 16 are close to the outer wall surfaces 3a and 4a, respectively. The spring is biased in the direction in which it is made to come into contact, that is, so as to abut.
[0007]
Thereby, the gap 2 is closed by allowing the relative displacement of each of the frames 3 and 4 in the left-right direction A and the front-back direction B, and intrusion of rainwater or the like from the outdoor 7 into the gap 2 is prevented.
[0008]
One end of each of the extension coil springs 21 and 22 is connected to substantially the center in the width direction of the second expansion joint 6, and the other end of each of the extension coil springs 21 and 22 is connected to each of the frames 3 and 4, respectively. Have been. Accordingly, the center position of the second expansion joint 6 in the width direction can be always arranged in the plane S including the center position of the gap 2 in the width direction. Referring to FIGS. 8 and 10, second expansion joint 6 has a width L2. For example, when each of skeletons 3 and 4 is displaced in the left-right direction A so as to be separated from each other, width of expansion joint 2 is equal to width L2. A displacement up to a difference L2-L0 from the width L0 of the gap 2 can be allowed.
[0009]
For example, the width L1 of the first expansion joint 5 and the width L2 of the second expansion joint 6 are selected to be substantially the same, and the allowable amount of each of the first expansion joints 5, 6 with respect to the relative displacement of each of the frames 3, 4 is set. Are chosen to be equal.
[0010]
Between the first expansion joints 5 and 6 configured as described above, the joint device 1 used to close a part 2 a of the exposed gap 2 includes a third cover plate 25. The third cover plate 25 has a height H1 and an upper portion 23 which has a width L3 substantially equal to the width L1 of the first cover plate 10 and is designedly continuous with the first cover plate 10; H2 and a lower portion 24 having a width L4 substantially equal to the width L2 of the second cover plate 1 and having a design and continuous with the second cover plate 16. This prevents the third cover plate 25 from damaging the appearance. The joint device 1 covers the first cover plate 10 of the first expansion joint 5 from the outside with the upper part 23 of the third cover plate 25 and the second cover plate 16 of the second expansion joint 6 with the lower part 24 of the cover plate 25 outdoors. And is attached to one of the first cover plates 10 and 16 to close a part 2 a of the gap 2.
[0011]
[Problems to be solved by the invention]
In this conventional technique, the third cover plate 25 is formed integrally and is connected to the first cover plate 10 of the first expansion joint 5 or the second cover plate 16 of the second expansion joint 6. For example, when each of the frames 3, 4 is attached to the first cover plate 10 of the first expansion joint 5 and is displaced away from each other in the left-right direction A, the relative displacement between the frames 3, 4 is reduced. When the lower portion 24 reaches the width L5 or more covering the frame 3, the gap 2a is exposed. This width L5 is smaller than the permissible amount L1-L0 of the first expansion joint 5, and the permissible amount of relative displacement between the frames 3, 4 is reduced. When each of the skeletons 3 and 4 is displaced in the front-back direction B, for example, when the skeleton 4 is displaced toward the outside 7 with respect to the skeleton 3, the first cover plate 10 is moved toward the outside 7 with respect to the second cover plate 16. Therefore, a gap is generated between the lower portion 24 of the cover plate 25 and the second cover plate 16. Conversely, when the skeleton 3 is displaced toward the outside 7 with respect to the skeleton 4, the second cover plate 16 is displaced toward the outside 7 with respect to the first cover plate 10. May be pressed against the second cover plate 16 and may be damaged by receiving an undesired external force.
[0012]
Further, when the third cover plate 25 of the joint device 1 is attached to the second cover plate 16 of the second expansion joint 6 and each of the frames 3, 4 is displaced so as to be relatively close in the left-right direction A, as described above. In addition, since the second expansion joint 6 is configured so that the center thereof coincides with the center of the gap 3, the upper portion 23 of the cover plate 25 is pressed against the side wall surface 12 and may be damaged by an undesired external force. There is. Conversely, when the frames 3 and 4 are displaced so as to be relatively separated from each other, the upper portion 23 and the side wall surface 12 are separated from each other, and a gap is generated. When each of the skeletons 3 and 4 is relatively displaced in the front-rear direction B, for example, when the skeleton 3 is displaced toward the outdoor 7 side with respect to the skeleton 4, when the first cover plates 10 and 16 Due to the relative positional relationship, a gap is generated between the upper portion 23 of the third cover plate 25 and the first cover plate 10. Conversely, when the skeleton 4 is displaced toward the outside 7 with respect to the skeleton 3, the upper portion 23 is pressed against the first cover plate 10 due to the relative positional relationship between the first cover plates 10 and 16 as described above, It may be damaged by receiving an undesired external force.
[0013]
Therefore, an object of the present invention is to allow displacement between the frames as in the case of the first and second cover plates, and to cause damage due to the relative displacement between the frames, or to allow the displacement between the first and second cover plates. It is an object of the present invention to provide a connection structure of an expansion joint device that can prevent a gap from being generated.
[0014]
[Means for Solving the Problems]
According to the present invention, one of the two skeletons adjacent to each other with a gap extending vertically has a convex outer wall portion projecting to the outdoor side from the outer wall surface of the other skeleton, In the convex outer wall portion, a first cover plate of a first expansion joint device extending from a side wall surface facing a gap of the convex outer wall portion to an outer wall surface of the other skeleton is provided so as to be angularly displaceable,
Each frame is provided with a second cover plate of a second expansion joint device extending between outer wall surfaces of each frame adjacent to the extending direction of the first cover plate,
A first cover body connected to the first cover plate, having a width substantially equal to the first cover plate, and a width substantially equal to the second cover plate between the first and second expansion joint devices; A third cover plate formed by the second cover body, which is connected to the first cover body so as to be angularly displaceable and is spring-biased into the gap by spring means provided on the first cover body; And

According to the present invention, two skeletons are adjacent to each other with a gap extending vertically, and one skeleton has a convex outer wall portion projecting to the outdoor side more than a flat outer wall extending vertically which the other skeleton has. Have. The first cover plate of the first expansion joint device is provided on the convex outer wall portion of one of the skeletons from the outer wall surface facing the gap to the outer wall surface of the other skeleton so as to be angularly displaceable. The gap is closed in an acceptable state, preventing rainwater or the like from entering the gap from outside. In addition, a second cover plate of the second expansion joint device is provided adjacent to the extending direction of the first cover plate and between outer wall surfaces of the respective frames so that relative displacement between the frames can be permitted. The air gap is closed, preventing rainwater from entering the air gap from outside. A third cover plate is provided between the first and second cover plates, and the third cover plate has a first cover body and a second cover body, and the first cover body is provided on the first cover plate. The second cover body is connected to the first cover body so as to be angularly displaceable, and is spring-biased in a direction of contacting each outer wall surface. Thus, even when the first and second cover members are displaced relative to each other, the third cover plate allows the relative displacement of each frame without receiving an undesired external force, and The gap exposed to the outside from the gap between the two expansion joint devices can be closed to prevent water from entering the gap from outside. Further, the first cover has substantially the same width as the first cover plate, and the second cover has substantially the same width as the second cover plate. Thereby, the gap can be closed by disposing the third cover plate between the first and second expansion joints without impairing the design appearance.
[0016]
【Example】
FIG. 1 is a perspective view showing a connection structure of an expansion joint device according to one embodiment of the present invention. The two skeletons 31, 32, which are the outer walls of the building, are provided adjacent to each other with a gap 33 extending vertically. The skeleton 31, which is the other skeleton disposed on the left side in FIG. 1, faces the outdoors and has a flat outer wall surface 31a extending vertically along one vertical plane. The skeleton 32, which is one of the skeletons disposed on the right side, has an outer wall surface 32a formed substantially in the same plane as the outer wall surface 31a of the other skeleton 31 and an outer wall surface 31a above the outer wall surface 32a. 2 has a convex outer wall surface 32b formed on a convex outer wall portion 38 protruding to the outside 34 side, that is, a front side perpendicular to the paper surface in FIG.
[0017]
Due to a sudden earthquake or unequal subsidence of the ground, each of the skeletons 31 and 32 is moved in the left and right direction, which is the direction in which the skeletons 31 and 32 approach / separate from each other, or in the arrow Y.
