Description

【発明の属する技術分野】
本発明は、圧縮型防振吊り体及び複合圧縮型防振吊り体に関し、詳しくは、例えばビル建築等々において各階を仕切っている天井躯体と天井との間に配置して上階の振動或いは振動より発する音を防止するようにした圧縮型防振吊り体及び複合圧縮型防振吊り体に関する。
【従来の技術】
高層建築ビル等に居住する者にとって、安心して居住できる条件として最も重視されるのが、上階からの振動或いは該振動より発する音を防止し、耳や皮膚感覚からの不快感を除去することである。同時に、建築物内における大小の各種配管より生ずる振動或いは該振動に伴って発せられる音を防止することも重視される居住条件の大事な一つである。
高層建築ビル等の各階を仕切っている天井躯体と天井との間に配置され、上階からの振動或いは該振動より発する音を防止するための圧縮型防振吊り体の一例について図２１乃至図２４を参照して説明する。
従来の一例である圧縮型防振吊り体５１は、図２１に示すように、鋼材からなる縦長のコ字型の２個の各フレーム５２、５２と、ゴム材からなる防振体５３との組合わせからなるものである。
前記２個の各フレーム５２、５２は、図２２に示すように、垂直片５４とこの垂直片５４の両端に直角に折曲された上片５５、下片５５’を有している。各フレーム５２、５２の上片５５の中央には、例えば後記する天井体７１（図２４参照）を係止支持する下部吊りボルト７２等を挿通する小孔６６を穿孔しているとともに、下片５５’の中央には円形孔５６を穿孔し、且つ、当該下片５５’の垂直片５４を中心とする左右いずれかの側の端部には上記円形孔５６の穿孔に連続した切り込み孔部５７を設けている。
前記切り込み孔部５７が設けられた各フレーム５２の上片５５又は下片５５’の端部と切り込み孔部５７を形成する両側端とが交叉する角部には、緩やかな湾曲部５８を形成している。
前記円形孔５６、切り込み孔部５７を設けた下片５５’には、当該切り込み孔部５７が設けられていない側の下片５５’の端部で前記垂直片５４側の隅部位置に後記する２個の各フレーム５２を止着する際のカシメ止め用等の小穴５９を設け、該小穴５９の対称隅部の位置にもカシメ止め用等の小穴５９’を設けている。
また、前記小孔６６を穿孔した上片５５にも、上記下片５５’に設けた各小穴５９、５９’に該当する同じ位置に各小穴５９、５９’を設けている。図２１中、６５はカシメ部材である。
前記防振体５３は、図２３に示すように、その中心に、この圧縮型防振吊り体５１を配置しながら該圧縮型防振吊り体５１を介して例えば図２４に示す天井体７１を係止支持する下部吊りボルト７２等や、例えば天井躯体７３から吊り下げられた上部吊りボルト７４を挿通する挿通孔６０を有している。
また、上下端部の近傍には各括れ部６１、６２を形成し、上方の括れ部６１の上方、即ち防振体５３の上端には鋼材等からなりワッシャーの作用を果たす座金６３を防振体５３に一体的に接合配置し、下方の括れ部６２の下方、即ち、防振体５３の下端には肉薄部６４を設けている。
上記構成の圧縮型防振吊り体５１によれば、各フレーム５２内に装着され圧縮する防振体５３自体及びその肉薄部６４をもって、例えば天井躯体７３に埋め込み方式等でもって堅固に固着された上部吊りボルト７４と天井体７１を係止支持する下部吊りボルト７２等との相互の振動伝達を遮断することができる。
【発明が解決しようとする課題】
しかしながら、従来の圧縮型防振吊り体５１の場合、実際の設置作業、組み立て作業を行う場合には、防振体５３の周囲の一対のフレーム５２、５２の間の極めて狭い空間において、天井躯体７３側の上部吊りボルト７４や天井体７１側の下部吊りボルト７４をダブルナット７５を使用し、スパナ等の工具を２種類左右の手で持ちながら各々締着する構造であるため、このダブルナット７５の締め付け作業は極めて面倒であり煩雑性、困難性を伴っていた。
また、前記従来の圧縮型防振吊り体５１の場合、吊り下げ支持する天井体７１側の荷重の大小に応じて防振体５３の直径や厚さを変えて対応するようにしている。
本発明は、従来における上記実情に鑑みて開発されたものであり、フレーム構造を改良し、製造コストを低減でき、且つ、実際の組み立て作業を簡略、迅速に行うことができるとともに複合圧縮型防振吊り体を提供することを目的とするものである。

請求項５記載に係る発明の圧縮型防振吊り体は、ビル建築等において各階を仕切っている天井躯体と天井との間に配置させて上階の振動或いは振動より発する音を防止する場合等に用いる圧縮型防振吊り体であって、垂直片と、この垂直片の両端に直角に、且つ、互いに反対方向に折曲形成された上片、下片とを有し、全体がクランク形状のフレームと、ゴム材により筒状に形成され、中心部を貫通して天井側の下部吊りボルト挿通用のボルト挿通孔を有するとともに、一端側に前記フレームの支持孔に嵌入固着させる小径筒部を有し、他端側に前記下部吊りボルト締着用の締着ナットを取り付けた防振体と、を備えてなり、前記上片に設けた天井躯体側から垂下する上部吊りボルトの挿通用のボルト挿通孔への当該上部吊りボルトを螺合させた状態での上部ナットによる締着、及び前記防振体のボルト挿通孔、締着ナットへの下部吊りボルトを挿通、螺合させた状態での下部ナットによる締着を、前記クランク形状のフレームの解放空間を利用して行うようにしたことを特徴とするものである。

そして、フレームがクランク形状であることから、防振体の側方に加えて上方も解放しており、これにより、天井躯体と、天井との間隔が狭いような状態においても、この圧縮型防振吊り体の組み付け設置作業を、飛躍的に容易、且つ、迅速に行うことができる。
【発明の実施の形態】
以下、添付図面を参照して本発明の実施の形態の圧縮型防振吊り体及び複合圧縮型防振吊り体について詳細に説明する。
（実施の形態１）
図１は本実施の形態１に係る圧縮型防振吊り体１の使用状態を示す概略断面図であり、図２は本実施の形態１に係る圧縮型防振吊り体１の側面図、図３は本実施の形態１に係る圧縮型防振吊り体１の正面図、図４は本実施の形態１に係る圧縮型防振吊り体１の平面図である。
本実施の形態１に係る圧縮型防振吊り体１は、ビル建築等々において各階を仕切っているコンクリートからなる天井躯体７３と、天井躯体７３の下方において下階の天井を形成する天井７１との間にこれを配置させて、上階の振動或いは振動より発する音の下階への伝導を防止する場合等々に用いるものである。
天井７１は、例えば、吸音材７４を配置した野縁７５、遮音ボード７６、化粧板７７を有している。
そして、図１に示すように、上部吊りボルト８１の上端を天井躯体７３に埋込固定した埋込インサート８３に螺合して、この上部吊りボルト８１を垂下状態とし、また、野縁７５に取り付けた野縁受８４に下部吊りボルト８２の下端側をナット８５を用いて取り付け、この下部吊りボルト８２を立ち上げるようにしている。
本実施の形態１の圧縮型防振吊り体１は、図２乃至図４に示すように、垂直片３と、該垂直片３の上下両端において直角に折曲形成された上片４、下片５とを有している。
この圧縮型防振吊り体１は、上片４には天井躯体７３側から垂下する上部吊りボルト８１の螺合用のねじ孔又は穴４ａを有し下片５には前記ねじ孔又は穴４ａと対応する配置で防振体嵌入固着用の支持孔５ａを有するＣ型チャンネル状に形成されたフレーム２と、ゴム材により円筒状に形成され中心部を貫通して天井７１側に位置する下部吊りボルト８２の挿通用のボルト挿通孔１１を有するとともに一端側に前記フレーム２の支持孔５ａに嵌入固着させる小径筒部１０ａを取り付け他端側に前記下部吊りボルト８２の締着用の締着ナット１３を重合配置に取り付けた防振体１０とを具備している。
なお、本実施の形態では、前記締着ナット１３の下端に接して締着ナット１３の下側に位置する別の締着ナットを具備しているが、この締着ナットの外周部の殆どは防振体１０の袋状に形成した上部外周で覆われるようになっている。
前記上片４のねじ孔又は穴４ａを、ねじ孔として構成した場合、Ｍ１０、Ｗ３／８共用ねじとして形成している。
また、前記垂直片３の形状は、単純な板状ではなく、図４に示すように、これを横断面から見た場合、両側端縁を「くの字状」に屈曲形成して機械的強度を増強している。更に、防振体１０の外周の一部は、防振体１０自体の強度向上及び外観体裁の向上を目的として凹凸部１０ｂとしている。
次に、本実施の形態１の圧縮型防振吊り体１の具体的使用状態を図１をも参照して説明する。
天井躯体７３と、天井７１との間において、前記防振体１０を固着している圧縮型防振吊り体１を組み付け設置するに際しては、上片４のネジ孔４ａへ上部吊りボルト８１の下端を螺合させ、更に上部ナット９１をスパナ等の工具を用いて締着して圧縮型防振吊り体１を上部吊りボルト８１に取り付ける。
また、下部吊りボルト８２を圧縮型防振吊り体１のボルト挿通孔１１に挿通するとともに、前記締着ナット１３へ下部吊りボルト８２を螺合させた状態で、締着ナット１３と下部ナット９２を下部吊りボルト８２の上端にスパナ等の工具を用いて締着し、これにより、図１、図２に示すように、上部吊りボルト８１、圧縮型防振吊り体１、下部吊りボルト８２及び野縁受８４を介して天井躯体７３の下方において天井７１を吊り下げ支持する。
このように、圧縮型防振吊り体１を組み付け設置する上述したスパナ等の工具を用いる作業は、前記フレーム２の上片４、下片５間の解放空間を利用して行うことができるので、前記従来例の場合と比較し、飛躍的に容易、且つ、迅速に行うことができる。また、上階の振動或いは振動より発する音の下階への伝導を防振体１０の防振作用で確実に防止することができる。
（実施の形態２）
次に、図５乃至図７を参照して本発明の実施の形態２に係る複合圧縮型防振吊り体１Ａについて説明する。
図５は本実施の形態２に係る複合圧縮型防振吊り体１Ａの正面図、図６は本実施の形態２に係る複合圧縮型防振吊り体１Ａの側面図、図７は本実施の形態２に係る複合圧縮型防振吊り体１Ａの平面図である。
本実施の形態２に係る複合圧縮型防振吊り体１Ａは、実施の形態１の圧縮型防振吊り体１を２又は２以上の複数個、例えば２個並列配置に組み合わせたものである。
即ち、例えば２個並列配置に組み合わせた複合圧縮型防振吊り体１Ａである場合は、２個の圧縮型防振吊り体１における上片４同士を、図中の破線で示す上部連結板２１の両端部からの前記両ねじ孔又は穴４ａへの２個のボルト２３の螺合締着により連結し、また、２個の圧縮型防振吊り体１における下片５同士を、前記２個の小径筒部１０ａに嵌入させた下部連結板２２の両端部からの前記締着ナット１３への２個のボルト２４の螺合締着により連結して、２個の圧縮型防振吊り体１を並列配置としている。
更に、上部連結板２１の中央部には上部吊りボルト８１の螺合用のねじ孔又は穴２１ａを設け、下部連結板２２の中央部には下部吊りボルト８２の螺合用のねじ孔又は穴２２ａを各々設けて、上部連結板２１のねじ孔又は穴２１ａへの上部吊りボルト８１の螺合及びナット締着、下部連結板２２の中央部に設けたねじ孔又は穴２２ａへの下部吊りボルト８２の螺合及びナット締着を、前記フレーム２の上片４、下片５間及び上部連結板２１、下部連結板２２間に形成される解放空間を利用して行うものである。
この複合圧縮型防振吊り体１Ａによれば、天井躯体７３と、天井７１との間において、圧縮型防振吊り体１Ａを組み付け設置する際の実施の形態１の場合と同様なスパナ等の工具を用いる組みつけ作業は、前記フレーム２の上片４、下片５間及び上部連結板２１、下部連結板２２間に形成される解放空間を利用して行うことができ、前記従来例の場合と比較し、飛躍的に容易、且つ、迅速に組みつけ作業行うことが可能となる。
また、この複合圧縮型防振吊り体１Ａによれば、既述した作用効果を発揮する圧縮型防振吊り体１を上部連結板２１、下部連結板２２を使用して２個並列配置に組み合わせた構造であるため、２個の防振体１０による防振作用を発揮させることができるとともに、圧縮型防振吊り体１に負荷荷重として作用する天井７１の重量が実施の形態１の場合よりも大きい場合にも容易に対応することが可能となる。
図８は上述した実施の形態２の複合圧縮型防振吊り体１Ａの応用例を示すものであり、２個の複合圧縮型防振吊り体１Ａを背中合わせに固定配置して、合計４個の防振体１０を有する複合圧縮型防振吊り体１Ｂとしたものである。
２個の複合圧縮型防振吊り体１Ａの背中合わせの固定配置は、一方の複合圧縮型防振吊り体１Ａの２個の垂直片３と、他方の複合圧縮型防振吊り体１Ａの２個の垂直片３とを各々接合させ、例えば溶接、ボルト、ナット止等で密着固定することにより行う。
この複合圧縮型防振吊り体１Ｂによれば、合計４個の防振体１０を有する構造であるため、４個の防振体１０による防振作用を発揮させることができるとともに、天井７１の重量がより大きい場合にも容易に対応することが可能となる。
図９は上述した実施の形態２の複合圧縮型防振吊り体１Ａの別の応用例を示すものであり、複合圧縮型防振吊り体１Ａに対して実施の形態１の圧縮型防振吊り体１をボルト２３、ナット止等の螺合締着により背中合わせに固定した構成した複合圧縮型防振吊り体１Ｃを示すものである。
この複合圧縮型防振吊り体１Ｃによれば、合計３個の防振体１０を有する構造であるため、３個の防振体１０による大きな防振作用を発揮させることができるとともに、天井７１の重量がより大きい場合にも容易に対応することが可能となる。
なお、図８、図９の圧縮型防振吊り体１Ｂ、１Ｃを組み付け設置するに際しては、例えば、前記上部連結板２１の上面、下部連結板２２の下面に夫々固着されて中央部に図中の破線で示すねじ孔又は穴２１ａを設けた最上部連結板２１Ａ、最下部連結板（図示せず）を具備し、最上部連結板２１Ａの中央部に設けたねじ孔又は穴２１ａへの上部吊りボルト８１の螺合及びナット締着し、最下部連結板の中央部に設けたねじ孔又は穴（図示せず）への下部吊りボルト８２の螺合及びナット締着すれば、フレーム２の上片４、下片５間及び上部連結板２１、下部連結板２２間の解放空間を利用して行うことができ、前記した従来例の場合と比較し、飛躍的に容易、且つ、迅速に組みつけ作業行うことが可能となる。
