【０００１】
【発明の属する技術分野】
本発明は、道路橋、橋梁、高架橋、高架鉄道、高架道路等の構造物、特に桁に好適な構造物の支承構造体及びその製造方法に関する。
【０００２】
【発明が解決しようとする課題】
例えば道路橋、橋梁、高架橋、高架鉄道、高架道路等の桁の支承構造体としては、車両自重、車両走行時における遠心力、風圧による揚力等の水平方向及び鉛直方向の荷重を支持し、転倒モーメント（曲げモーメント）にも耐え、しかも、桁の伸縮、撓みをも許容するものであることが、当然要求される。
【０００３】
斯かる桁の支承構造体として、特公昭５７−２５６８３号公報及び特公昭５８−２５８０４号公報等で提案されており、桁の伸縮に対応するために、特公昭５７−２５６８３号公報に記載の支承構造体は、ボールスタッドとこれを受容するハウジング内に配された支圧板とを具備しており、特公昭５７−２５６８３号公報に記載の支承構造体は、球体部を有した下沓と球体部を受容する支圧摺動部材が内部に配された上沓とを具備している。
【０００４】
しかしながら、斯かる公報に記載のいずれの支承構造体も、構造が複雑であって施工に手間がかかり、汎用性に乏しく、しかも、震動エネルギに対する減衰作用をほとんど有しないために、地震等においては桁の震動がいつまでも続く場合がある。
【０００５】
本発明は、前記諸点に鑑みてなされたものであって、その目的とするところは、構造が簡単であって、施工に手間がかからず、汎用性に優れた構造物の支承構造体及びその製造方法を提供することにある。
【０００６】
本発明の他の目的とするところは、桁等の構造物の伸縮、撓みを許容でき、しかも、容易に桁等の構造物の震動エネルギを吸収することができる支承構造体及びその製造方法を提供することにある。
【０００７】
【課題を解決するための手段】
本発明の第一の態様の構造物の支承構造体は、内部に充填材が充填された鋼製外殻部材を有していると共に、地盤に支持されて地盤上に立設された支柱本体と、支柱本体の充填材内に下端部が配されて支柱本体に当該下端部で保持されていると共に、支柱本体から上方に突出すると共に上端部に桁等の構造物が固着されるようになっている上部支柱とを具備しており、ここで、上部支柱の上端部及び下端部は、内部に充填材が充填された鋼製外殻部材からなる。
【０００８】
第一の態様の構造物の支承構造体によれば、地盤上に立設された支柱本体に、上部支柱がその下端部で保持されており、斯かる上部支柱の鋼製中空角体からなる上端部に桁等の構造物が固着されるようになっているので、構造がきわめて簡単であって施工が容易であり、しかも、後述の桁等の構造物の伸縮若しくは撓み又は誤差を吸収するように容易にでき、汎用性にきわめて優れている。
【０００９】
上端部及び下端部において、その鋼製外殻部材は、本発明の第二の態様のように、連続な鋼製角筒体からなっていてもよいが、本発明の第三の態様のように、その鋼製外殻部材の夫々は、鋼製角筒体からなり、当該鋼製角筒体は、上端部の鋼製角筒体の内部と下端部の鋼製角筒体の内部とを互いに連通する貫通孔を有した連結部材を介して互いに連結固定されていてもよく、本発明の第四の態様のように、上端部の鋼製外殻部材は、鋼製角筒体からなり、下端部の鋼製外殻部材は、鋼製円筒体からなっていてもよく、ここで、鋼製角筒体と鋼製円筒体とは、本発明の第五の態様のように、鋼製角筒体の内部と鋼製円筒体の内部とを互いに連通する貫通孔を有した連結部材を介して互いに連結固定されていてもよい。
【００１０】
上部支柱の下端部は、本発明の第六の態様のように、鋼製外殻部材の内部に充填された充填材に直接埋め込まれて支柱本体に固定されていても、更には、本発明の第七の態様のように、当該下端部と鋼製外殻部材の内部に充填された充填材との間に介装された弾性手段を介して支柱本体に保持されていてもよい。
【００１１】
第二の態様のように上端部及び下端部の鋼製外殻部材が連続な鋼製角筒体からなっていると、更に簡単な構造となる上に、施工が容易となり、第三の態様のように上端部及び下端部の鋼製外殻部材の夫々が連結部材を介して互いに連結固定された鋼製角筒体からなっていると、下端部の施工後に上端部を施工できるので、長尺の上部支柱の取り扱いによる不都合をなくし得、第四の態様のように下端部の鋼製外殻部材が鋼製円筒体からなっていると、施工が容易である上に、当該下端部の周りへの隙間なしの充填材の充填作業が容易になり、ここで、第五の態様のように鋼製角筒体と鋼製円筒体とが連結部材を介して互いに連結固定されていると、第三の態様と同様に、長尺の上部支柱の取り扱いによる不都合をなくし得、第六の態様のように、上部支柱の下端部が鋼製外殻部材の内部の充填材に直接埋め込まれていると、上記同様に施工を容易に行い得、しかも、上部支柱の下端部の支柱本体への固定的な保持が強固になり、第七の態様のように、上部支柱の下端部が弾性手段を介して支柱本体に可動的に保持されていると、桁等の構造物等の伸縮若しくは撓み又は誤差を許容できるようにし得、しかも、例えば弾性手段に高減衰ゴム等を用いて弾性手段に震動エネルギ吸収機能を付加すると、容易に桁等の構造物の震動エネルギを吸収でき、地震における構造物の震動を可及的速やかに減衰させることができる。
【００１２】
弾性手段は、本発明の第八の態様のように、上部支柱の下端部の周りに配された弾性体からなっていてもよく、また本発明の第九の態様のように、支柱本体の充填材内に埋め込まれていると共に、内部に上部支柱の下端部が配された有底の中空体を更に具備していてもよく、この場合、弾性体は、中空体と上部支柱の下端部との間に介装されていても、更に、斯かる中空体と上部支柱の下端部との間に介装された弾性体は、本発明の第十の態様のように、上部支柱の下端部の下面と中空体の底部内面との間に介装された積層ゴムと、上部支柱の下端部の側面と中空体の側内周面との間に介装された弾性材とを具備していてもよい。

【００１４】
また本発明の第十一の態様のように、好ましくは、上部支柱の下端部の周りの充填材は、無収縮コンクリートモルタルであって、上部支柱の下端部よりも下方の充填材は、コンクリートであるが、本発明はこれらに限定されず、いずれの充填材も、無収縮コンクリートモルタル又はコンクリートであってもよい。
【００１５】
更に本発明の第十二の態様のように、上端部及び下端部の鋼製外殻部材の内部に充填材を充填し、ここで斯かる充填材を、本発明の第十三の態様のように、コンクリートとしてもよいが、無収縮コンクリートモルタルでもよい。第十二の態様の構造物の支承構造体では、機械的に強固な上部支柱とでき、大きな荷重を受けることができる。
【００１６】
本発明では、その第十四の態様のように、上部支柱の上端部には、構造物の一端部が固着されるようになっており、支柱本体の充填材内には、他の上部支柱の下端部が配されて支柱本体に保持されており、支柱本体から上方に突出する他の上部支柱の上端部には、構造物の一端部との間に隙間をもって対峙して配された他の桁等の他の構造物の一端部が固着されるようになっており、他の上部支柱の上端部及び下端部は、内部に他の充填材が充填された他の鋼製外殻部材からなっていてもよく、ここで、本発明の第十五の態様のように、他の上部支柱の上端部及び下端部の他の鋼製外殻部材は、連続な鋼製角筒体からなり、本発明の第十六の態様のように、他の上部支柱の上端部及び下端部の他の鋼製外殻部材の夫々は鋼製角筒体からなり、当該上端部及び下端部の鋼製角筒体は、当該上端部の鋼製角筒体の内部と当該下端部の鋼製角筒体の内部とを互いに連通する貫通孔を有した連結部材を介して互いに連結固定されており、本発明の第十七の態様のように、他の上部支柱の下端部は、支柱本体の充填材に直接埋め込まれて支柱本体に固定されており、本発明の第十八の態様のように、他の上部支柱の下端部は、当該下端部と支柱本体の鋼製外殻部材の内部に充填された充填材との間に介装された他の弾性手段を介して支柱本体に保持されており、ここで、他の弾性手段は、本発明の第十九の態様のように、他の上部支柱の下端部の周りに配された他の弾性体からなり、本発明の第二十の態様のように、支柱本体の充填材内に埋め込まれていると共に、内部に他の上部支柱の下端部が配された他の有底の中空体を具備しており、他の弾性体は、他の中空体と他の上部支柱の下端部との間に介装されており、ここで、他の弾性体は、第二十一の態様の構造物の支承構造体では、他の上部支柱の下端部の下面と他の中空体の底部内面との間に介装された他の積層ゴムと、他の上部支柱の下端部の側面と他の中空体の側内周面との間に介装された他の弾性材とを具備している。
【００１７】
上記の第十四の態様から第二十一の態様の構造物の支承構造体において好ましくは、本発明の第二十二の態様のように、他の上部支柱の他の鋼製外殻部材の内部に他の充填材が充填されており、斯かる充填材は、好ましくは、本発明の第二十三の態様のように、コンクリートである。
【００１８】
本発明の第十四から第二十三の夫々の態様では、少なくとも二個の上部支柱を具備した支承構造体を、少なくとも一個の上部支柱を具備した支承構造体における上記と同様な効果をもって提供できる。なお、二個の構造物を固定のみ又は可動のみに支持するように両方の上部支柱を構成してもよく、構造物のいずれか一方を固定に、その他方を可動に夫々支持するように二個の上部支柱を構成してもよい。
【００１９】
本発明の第一の態様の構造物の支承構造体の製造方法は、支柱本体のための鋼製外殻部材をその下端部で地盤に支持し、鋼製外殻部材の内部に充填材を充填して、鋼製外殻部材と充填材とからなる支柱本体を地盤上に立設すると共に、充填材の充填途中において、上部支柱の下端部のための鋼製外殻部材を支柱本体の鋼製外殻部材の内部に挿入して充填された充填材内に配するようにして、当該上部支柱の下端部のための鋼製外殻部材を支柱本体に保持して、支柱本体から上方に突出し、桁等の構造物を固着するための鋼製外殻部材からなる上端部を有する上部支柱をその下端部において支柱本体に保持することからなる。
【００２０】
本発明の第一の態様の構造物の支承構造体の製造方法によれば、地盤上に立設された支柱本体の鋼製外殻部材への充填材の充填途中において上部支柱の下端部を鋼製外殻部材の内部に挿入して充填された充填材内に配するようにして、而して上部支柱の下端部のための鋼製外殻部材を支柱本体に保持するために、施工が極めて簡単であって、手間がかからず、早期に構造物の支承構造体を製造できる。
【００２１】
本発明の製造方法において、第二の態様のように、上端部及び下端部の鋼製外殻部材は、連続な鋼製角筒体からなっていてもよく、また、第三の態様のように、上部支柱の下端部のための鋼製外殻部材を支柱本体に保持した後に、当該上部支柱の下端部のための鋼製外殻部材に、上部支柱の下端部のための鋼製外殻部材とは別体の鋼製外殻部材を連結部材を介して連結固定して、桁等の構造物を固着するための鋼製外殻部材からなる上端部を形成するようにしてもよく、更に、第四の態様のように、鋼製外殻部材からなる上端部の形成後、当該鋼製外殻部材の内部に充填材を充填するようにしてもよく、また、第五の態様のように、支柱本体の鋼製外殻部材の内部に充填された充填材と上部支柱の下端部のための鋼製外殻部材との間に弾性手段が介在するように、当該上部支柱の下端部のための鋼製外殻部材を支柱本体の鋼製外殻部材の内部への挿入に際して、弾性手段を支柱本体の鋼製外殻部材の内部に配するようにしてもよく、加えて、第六の態様のように、支柱本体の鋼製外殻部材の内部への充填材の充填において、上部支柱の下端部のための鋼製外殻部材の支柱本体の鋼製外殻部材の内部への挿入前は、充填材としてコンクリートを、上部支柱の下端部のための鋼製外殻部材の支柱本体の鋼製外殻部材の内部への挿入後は、充填材として無収縮コンクリートモルタルを夫々充填するようにしてもよく、第七の態様のように、上部支柱の下端部のための鋼製外殻部材の支柱本体への保持後、上部支柱の下端部のための鋼製外殻部材の内部に充填材を充填するようにしてもよい。
【００２２】
本発明において、構造物としては、道路橋、橋梁、高架橋、高架鉄道、高架道路等の桁を好ましいものとして挙げることができるが、その他の桁であってもよい。
【００２３】
【発明の実施の形態】
次に本発明及びその実施の形態を、図を参照して更に詳細に説明する。なお、本発明はこれら実施の形態に何等限定されないのである。
【００２４】
図１から図３において、本例の構造物の支承構造体１は、内部に充填材２が充填された円筒状の鋼製外殻部材３を有していると共に、下端部で地盤（図示せず）そのもの又は基礎もしくは基台を含む地盤に支持されて地盤上に立設された円柱状の支柱本体４と、支柱本体４の充填材２内に下端部５が配されて支柱本体４に当該下端部５で保持されており、支柱本体４から上方に突出すると共に上端部６に構造物としての桁７及び８の夫々の一端が固着されるようになっている上部支柱９とを具備している。
【００２５】
充填材２は、本例では、上部支柱９の下端部５の周りでは、無収縮コンクリートモルタル１１であって、上部支柱９の下端部５の下面１２よりも下方では、コンクリート１３である。
【００２６】
上端部６及び下端部５は、例えばコンクリートからなる充填材１４が内部に充填された鋼製外殻部材１５からなり、鋼製外殻部材１５は、連続な鋼製角筒体、すなわち一体形成された鋼製の中空四角柱体からなっている。鋼製外殻部材１５の上端及び下端には、蓋板１６と貫通孔１７を有した底板１８とが夫々溶接により面一となるように固着されている。
【００２７】
上部支柱９の下端部５は、本例では、鋼製外殻部材３の内部に充填された無収縮コンクリートモルタル１１に直接埋め込まれて支柱本体４に固定されている。
【００２８】
桁軸方向に配された桁７及び８は、溶接等により鋼製外殻部材１５の各側面に固着されており、鋼製外殻部材１５を介して相互に連結されている。
【００２９】
桁７及び８の夫々の一端部を固定支持するようになっている以上の支承構造体１においては、地盤上に立設された支柱本体４に上部支柱９がその下端部５で保持されて、斯かる上部支柱９の鋼製外殻部材１５からなる上端部６に桁７及び８が固着されるようになっているので、構造がきわめて簡単であって施工が容易であり、しかも、後述の桁７及び８の伸縮又は撓みを吸収するように容易に構成でき、汎用性にきわめて優れており、また、上部支柱９の下端部５が無収縮コンクリートモルタル１１に直接埋め込まれているので、施工を容易に行い得ると共に上部支柱９の下端部５の支柱本体４への保持を強固に行い得、加えて、上部支柱９の鋼製外殻部材１５が連続な鋼製角筒体からなっているために、更に簡単な構造となる上に施工が容易となり、その上、鋼製外殻部材１５の内部に充填材１４が充填されているために、優れた機械的強度をもった上部支柱９となる。
【００３０】
支承構造体１を製造するには次のようにする。まず、支柱本体４のための鋼製外殻部材３をその下端部で地盤に支持し、上部支柱９の下端部５のための鋼製外殻部材１５の鋼製外殻部材３の内部への挿入前は、鋼製外殻部材３の内部に充填材２としてコンクリート１３を上方から充填して、鋼製外殻部材３と充填材２としてのコンクリート１３とからなる支柱本体４を地盤上に立設すると共に、上部支柱９の下端部５のための底板１８付きの鋼製外殻部材１５を支柱本体４の鋼製外殻部材３の内部に挿入し、この挿入後、充填材２として無収縮コンクリートモルタル１１を上方から充填して、当該鋼製外殻部材１５を、充填された充填材２としての無収縮コンクリートモルタル１１の内部に配するようにして、上部支柱９の下端部５のための鋼製外殻部材１５を支柱本体４に保持し、この保持後、上部支柱９の下端部５及び上端部６のための鋼製外殻部材１５の内部に充填材１４としてコンクリートを上方から充填し、この充填後、蓋板１６を鋼製外殻部材１５の上端に溶接等により固着し、こうして、支柱本体４から上方に突出し、桁７及び８を固着するための鋼製外殻部材１５からなる上端部６を有する上部支柱９をその下端部５において支柱本体４に保持して、支柱本体４と上部支柱９とからなる支承構造体１を得るようにする。本製造方法では、上端部６及び下端部５の鋼製外殻部材１５は連続な鋼製角筒体を用いている。
【００３１】
なお、鋼製外殻部材３の内部に予め充填材２としてのコンクリート１３が充填された支柱本体４を準備し、これを地盤上に立設するようにしてもよく、また、無収縮コンクリートモルタル１１の充填は、コンクリート１３の硬化前又は硬化後であってもよく、更に、鋼製外殻部材１５の内部に予め充填材１４としてのコンクリートが充填された上部支柱９を準備し、これを鋼製外殻部材３の内部に挿入するようにしてもよい。
【００３２】
桁７及び８を固定に支持する支承構造体１では、上部支柱９の下端部５を無収縮コンクリートモルタル１１に直接埋め込んで支柱本体４に固定して保持したが、これに代えて、図４から図６に示すように、下端部５と鋼製外殻部材３の内部に充填された無収縮コンクリートモルタル１１との間に介装された弾性手段としての天然ゴム、合成ゴム等のゴム等からなる弾性体２１を介して上部支柱９の下端部５を支柱本体４に保持してもよい。本例では、弾性体２１は、下面１２を含む下端部５の全ての周りに配されている。また、図１から図３に示す支承構造体１では、連続な鋼製角筒体、すなわち一体形成された鋼製の中空四角柱体からなる鋼製外殻部材１５でもって上部支柱９を構成したが、これに代えて、図４から図６に示すように、鋼製角筒体からなる上端部６の鋼製外殻部材１５を連結部材２５の上面に、有底の鋼製円筒体からなる下端部５の鋼製外殻部材１５を連結部材２５の下面に夫々溶接等により固着し、こうして、鋼製角筒体の内部と鋼製円筒体の内部とを互いに連通する貫通孔２６を有した連結部材２５を介して上端部６の鋼製角筒体と下端部５の鋼製円筒体とを互いに連結固定して、上部支柱９を構成してもよい。
【００３３】
図４から図６に示す桁７及び８を可動に支持する支承構造体３１では、下端部５の施工後に上端部６を施工できるので、長尺の上部支柱９の取り扱いによる不都合をなくし得、弾性体２１を介して支柱本体４に上部支柱９を保持しているために、弾性体２１の弾性伸縮により桁７及び８の桁軸方向（長手方向）の伸縮、撓みを許容でき、しかも、弾性体２１に例えば高減衰ゴム等を用いて、弾性体２１に弾性機能に加えて震動エネルギ吸収機能を付加すると、容易に桁７及び８の震動エネルギを吸収でき、地震における桁７及び８の震動を可及的速やかに減衰させることができる。また、支承構造体３１のように、下端部５の鋼製外殻部材１５が鋼製円筒体からなっていると、施工が容易である上に、下端部５の周りへの隙間なしの無収縮コンクリートモルタル１１の充填作業が容易になる。
【００３４】
図４から図６に示す支承構造体３１を製造するには、上記の製造方法において、支柱本体４の鋼製外殻部材３の内部に充填されたコンクリート１３及び無収縮コンクリートモルタル１１と上部支柱９の下端部５のための鋼製外殻部材１５との間に弾性体２１が介在するように、上部支柱９の下端部５のための鋼製外殻部材１５を支柱本体４の鋼製外殻部材３の内部への挿入に際して、弾性体２１を支柱本体４の鋼製外殻部材３の内部に配し、上部支柱９の下端部５のための鋼製外殻部材１５を支柱本体４に保持後に、下端部５のための鋼製外殻部材１５の内部に充填材１４としてのコンクリートを充填し、その後、支柱本体４に保持された上部支柱９の下端部５のための鋼製外殻部材１５に連結部材２５の下面を溶接固定して、次に、上部支柱９の下端部５のための鋼製外殻部材１５とは別体の鋼製外殻部材１５を連結部材２５の上面に溶接固定し、こうして、下端部５のための鋼製外殻部材１５に、当該下端部５のための鋼製外殻部材１５とは別体の鋼製外殻部材１５を、連結部材２５を介して連結固定して、この固定後、連結部材２５の上面に固定された鋼製外殻部材１５の内部に充填材１４としてのコンクリートを充填し、桁７及び８を固着するための鋼製外殻部材１５からなる上端部６を形成する。
【００３５】
なお、弾性体２１を支柱本体４の鋼製外殻部材３の内部に予め配する代わりに、下端部５のための鋼製外殻部材１５の外面に弾性体２１を予め被せて、こうして弾性体２１が被せられた下端部５のための鋼製外殻部材１５を支柱本体４の鋼製外殻部材３の内部に配してもよく、また、下端部５のための鋼製外殻部材１５を支柱本体４に保持後に、当該鋼製外殻部材１５の内部に充填材１４を充填したが、これに代えて、別体の鋼製外殻部材１５を連結部材２５の上面に溶接固定後に、当該鋼製外殻部材１５の内部への充填材１４の充填と共に、貫通孔２６を介して下端部５のための鋼製外殻部材１５の内部への充填材１４の充填を行ってもよく、更には、下端部５のための鋼製外殻部材１５と当該鋼製外殻部材１５に溶接固定された連結部材２５との組み合わせ体又は下端部５のための鋼製外殻部材１５とこれとは別体の鋼製外殻部材１５とが連結部材２５を介して相互に連結固定された組み合わせ体を予め形成し、この組み合わせ体の下端部５のための鋼製外殻部材１５を支柱本体４の鋼製外殻部材３の内部に挿入するようにしてもよく、この場合、挿入前に充填材１４を組み合わせ体に予め充填しておいてもよい。
【００３６】
上記例では、一個の上部支柱９を支柱本体４に保持するようにしたが、図７から図１０に示すように、桁７の一端を固定に支持する上部支柱４１と、桁７の一端との間に隙間をもって対峙して配された桁８の一端を可動に支持する上部支柱４２とを支柱本体４に保持して支承構造体４３を構成してもよく、ここで、上部支柱４１は、前記の弾性手段としての弾性体２１及び後述の弾性手段４４を介することなしに支柱本体４に保持されており、上部支柱４２は、弾性手段４４を介して支柱本体４に保持されている。また、前記の支承構造体３１では、上部支柱９の上端部６を鋼製角筒体から、その下端部５を有底の鋼製円筒体から夫々構成したが、これに代えて、図７から図１０に示す上部支柱４１及び４２の夫々のように、上端部６及び下端部５の鋼製外殻部材１５の夫々を鋼製角筒体から構成し、当該上端部６及び下端部５の鋼製角筒体を、上端部６の鋼製角筒体の内部と下端部５の鋼製角筒体の内部とを互いに連通する貫通孔２６を有した連結部材２５を介して互いに連結固定して支承構造体４３を構成してもよい。
【００３７】
図７から図１０に示す弾性手段４４は、弾性体５１と、支柱本体４の無収縮コンクリートモルタル１１内に埋め込まれていると共に、内部に上部支柱４２の下端部５が配された有底の中空体５２とを具備しており、弾性体５１は、中空体５２の内部において、上部支柱４２の下端部５の下面１２と中空体５２の底部内面５３との間に介装された積層ゴム５４と、上部支柱４２の下端部５の両側面５５及び５６と中空体５２の両側内周面５７及び５８との間に、取付板５９及び６０を介して介装された弾性材６１及び６２とを具備している。下面１２及び底部内面５３に上面及び下面で固定された積層ゴム５４は、鋼板とゴム板、好ましくは高減衰ゴム板とを交互に積層してなり、積層方向において桁８の一端からの荷重を支持し、積層方向に対して直交する方向において桁８の桁軸方向（長手方向）の伸縮及びこの桁軸方向に直交する方向の揺動に基づいて弾性的に剪断変形するようになっており、取付板５９及び６０を介して両側面５５及び５６に固着された天然ゴム、合成ゴム等のゴム等、好ましくは高減衰ゴムからなる弾性材６１及び６２は、桁８の桁軸方向に直交する方向の揺動に基づいて弾性的に伸縮変形するようになっている。
【００３８】
図７から図１０に示す支承構造体４３では、中空体５２の内部に低粘度充填材６５が充填されており、中空体５２の上方開口端の鍔部６６と連結部材２５との間には、弾性シール材６７が配されており、弾性シール材６７により中空体５２の内部への塵埃の侵入及び中空体５２の内部からの低粘度充填材６５の漏出が防止されるようになっている。なお、上部支柱４２の下端部５に、当該下端部５に取り付けられた弾性材６１及び６２と直交する面側を相互に連通すると共に、当該弾性材６１及び６２と平行に伸びる貫通孔を設け、斯かる貫通孔を設けることにより桁軸方向に直交する方向の揺動により生じる低粘度充填材６５の内圧が上がらないようにし、而して、中空体５２の内部からの低粘度充填材６５の漏出を防止するようにしてもよい。
【００３９】
