Description

【０００１】
【発明の属する技術分野】
この発明は、折板と称される金属製の屋根板を支持して屋根を形成するための屋根板支持具に関し、より詳しくは、断熱部を有する屋根板支持具に関する。
【０００２】
【従来の技術】
屋根板支持具は、Ｈ鋼やＣ型鋼、既設の屋根、下葺屋根等の下地材の上に固定してから、屋根板を固定（支持）する。そして、断熱性を持たせるときには、支持した屋根板の熱が下地材に伝わらないように、上下方向での熱伝導を遮断する断熱部を有した屋根板支持具を使用する。
【０００３】
この断熱部は合成樹脂で形成しており、その成形の自由度の高さゆえに、様々に形成されている。
【０００４】
例えば、特開平９−３２８８６９号や特開平１１−１４１０６１号に開示されている支持具がその一例である。この支持具は、下地材に固定する横方向２分割のサドルで構成されており、このサドルの上部に屋根板を固定する屋根板支持金具を保持した構成である。上記サドルはすべて合成樹脂製である。つまり合成樹脂の塊で屋根板を支持する。
【０００５】
このように構成した支持具では、充分な強度が得にくい上に、合成樹脂を多く使用するので、資源の有効利用の点で難点がある。
【０００６】
また、上記支持具は、固定した金属製の屋根板が、温度変化により伸縮するときに生じる歪を吸収するために、屋根板を支持する支持部を屋根板の伸縮方向に摺動可能にしたものであり、上記サドルの上部に逆Ｔ字形溝を形成して、この逆Ｔ字形溝に屋根板を固定する屋根板支持金具を摺動自在に支持している。
【０００７】
しかし、上述のように上記サドルは、合成樹脂の塊であるので、火事になればすべてが焼失してしまい、屋根が飛んでしまうことになる。
【０００８】
そこで特許第３０１９９９３号の屋根板支持具を案出した。この屋根板支持具は、下地材の上に固定する下部材上に、屋根板係止用の係止部材を有した上部材を屋根板の長さ方向、すなわち前後方向に摺動可能に載置し、上部材と下部材の相互間に、合成樹脂製の断熱部材を組み込んだ構成である。この屋根板支持具によれば、上述のような問題点は解決できるが、この場合も合成樹脂特有の成形性のよさに依存しがちであり、強度や美感の点から、比較的大きな形の断熱部材を使用する傾向があった。大きさが大きければ、合成樹脂の使用量は多くなってしまう。
【０００９】
【発明が解決しようとする課題】
そこでこの発明は、断熱機能を果たすための材料、すなわち合成樹脂や合成ゴムの使用量を極力抑えることができるとともに、充分な強度も得られるようにすることを主たる課題とする。
【００１０】
【課題を解決するための手段】
そのための手段は、下地材の上に固定するための固定金具と、屋根板を支持して前後方向に摺動可能な摺動金具と、これらの間に位置して上下方向での熱伝導を遮断する断熱部材とを有した屋根板支持具であって、上記固定金具の上部と摺動金具の下部には、熱伝導の遮断に必要な適宜間隔を隔てて相互に噛み合い、上記摺動方向での移動を可能とする噛み合い構造部を形成し、該噛み合い構造部間に、上記断熱部材を取り付けて、該断熱部材には、上記固定金具が挟む板状の被挟持片と、該被挟持片の上端部で水平方向に延びる板状の受け片部と、該受け片部の前後左右に張り出す縁部を形成し、断熱部材の上端部に、上記摺動金具の下端部に左右方向内側に向けて開口した摺動溝部が摺動可能な摺動レール部を形成した屋根板支持具であることを特徴とする。
【００１１】
上記噛み合い構造は、例えばＴ字形のレールとこの上部を抱きかかえる形の溝のように、上下方向に相互に噛み合って、上下方向で分離不可にするとともに、前後方向には摺動を可能にする形状のものである。そして相互間には、熱伝導の遮断に必要な適宜の間隔を形成する。この間隔は、例えば断熱部材にＡＢＳ樹脂のような合成樹脂を用いる場合、およそ５mm〜１０mm程度あれば足りる。
【００１２】
このような構成の屋根板支持具では、下地材に対して固定金具を用いて固定し、この固定金具の上に摺動可能に取り付けた摺動金具に対して、屋根板を支持する。この状態で屋根板が熱により伸縮すると、屋根板の伸縮に追随して摺動部材が前後方向に摺動し、屋根板に溜まるストレスを解消する。支持した屋根板の熱は、摺動金具には伝わるものの、断熱部材が熱伝導を遮断するので、固定金具には伝導されない。
【００１３】
また、固定金具の上部と摺動金具の下部に、互いに噛み合う噛み合い構造を形成しているので、合成樹脂等からなる断熱部材が介在しても強度は高く、正圧にも負圧にも充分に耐えるようにすることができる。また、万が一断熱部材が火災で焼失するようなことがあっても、固定金具と摺動金具の一体性を保持することができ、屋根が飛んでしまうような不都合を防ぐこともできる。さらに、上記噛み合い構造の間隔は熱伝導の遮断に必要な間隔であるので、薄くコンパクトな形状に形成できる。
【００１４】
その断熱部材は、固定金具が挟む板状の被挟持片と、同じく板状の受け片と、受け片の前後左右に形成した縁部とを有する形状であるので、厚みの薄い形状に形成できる。
【００１５】
なお、前記固定金具および／または摺動金具は、左右一対の挟持部材で構成するとよい。固定金具を左右一対の挟持部材で形成すると、断熱部材の被挟持部をより薄く形成できるうえに、下地材が屋根である場合にその下地材に対する固定構造の形成も容易である。また、摺動金具を左右一対の挟持部材で形成すると、断熱部材の前記摺動レール部への取り付け作業が容易である。
【００１６】
また、前記固定金具の上部における前後方向の両側には、前記断熱部材の対応位置に形成した被係合部に係合して上下方向で分離不能とする係合部を形成するもよい。係合部と被係合部が係合することにより、固定金具と断熱部材とを単に組み合わせるだけで、上下方向での分離が不能となる。このため、一体性が高まり、高い強度を得られることができる。
【００１７】
さらに、前記固定金具の前後方向の適宜位置に、左右方向に締め付けを行う締結具を保持し、上記摺動金具の前後方向中間位置を固定金具の前後方向中間位置に対応させたときに、上記摺動金具における上記締結具に対応する位置に、目印を形成するもよい。すなわち、締結具を締めて屋根板支持具を固定したときに、目印を締結具に合わせることで、摺動金具の前後方向中間位置と固定金具の前後方向中間位置とが対応して、摺動金具は前方へも後方へも等距離摺動可能な状態となる。締結具の締結作業をして固定を行ったときに、その作業対象である締結具を基準に位置合わせできるので、位置合わせの間違いや、し忘れ等の不都合を防止できる。
【００１８】
別の手段は、前記屋根板支持具を用いる屋根構造であることを特徴とする。
【００１９】
【発明の実施の形態】
この発明の一実施の形態を、以下図面を用いて説明する。
図１は、屋根板支持具１（以下、支持具という）の斜視図であり、この支持具１は、図２に示したように、下葺屋根２の上に上葺屋根３を形成して、断熱・防音性を有した屋根４を得るのに使用するためのものである。そしてこの支持具１は、下地材としての下葺屋根２に固定する固定金具５の上に、屋根板３ａを支持して前後方向に摺動する摺動金具６を、上下方向での熱伝導を遮断する断熱部を介して取り付けて構成している。
【００２０】
この一例では、断熱部を別部材、すなわち合成樹脂製の断熱部材７で構成し、固定金具５の上部に取り付けて、摺動金具６との間に介装した例を示している。
【００２１】
固定金具５は、図３にも示すように、左右一対の金属板製の第１挟持部材８，８からなる。これら第１挟持部材８，８は、下葺屋根２の馳締部２ａを挟み込んで締め付けることにより、下葺屋根２上に固定するものである。
【００２２】
すなわち、下端部には、略水平に延びる接地片９を設け、この接地片９の左右方向内側縁から上へ、左右方向外方に略半円形に膨出するように延設して、ぬすみ部１０を形成し、該ぬすみ部１０の上端から、垂直に立ち上がる挟持片１１を延設し、挟持片１１の上端からは左右方向外方に直角に折曲する受け片１２を形成している。
【００２３】
この固定金具５の上部には、上記断熱部材７を介して摺動金具６を取り付けるのであって、固定金具５の上部と、摺動金具６の下部には、熱伝導の遮断に必要な適宜間隔を隔てて相互に噛み合い、上記摺動方向での移動を可能とする噛み合い構造を形成する。上記受け片１２がその噛み合い構造の一方である。
【００２４】
また、上記挟持片１１の中央部には、角孔１３を形成して、第１挟持部材８，８同士を左右に締め付ける締結具を挿通できるようにしている。締結具としてはボルト１４ナット１５を用いた。さらに、受け片１２から挟持片１１、挟持片１１からぬすみ部１０に掛けては、外方へ凸のリブ１６を形成して補強している。
【００２５】
上述のように、締め付けによる下葺屋根２への固定は、挟持片１１で行う。このため、挟持片１１の上下方向の中間位置より下側を、下側ほど前後方向に幅広となるよう、末広がり状の幅広に形成し、ぬすみ部１０および接地片９は、その幅のまま形成している。
【００２６】
図中、１７は、固定用のヘクスを挿通する貫通孔である。
【００２７】
上記断熱部材７は、合成樹脂で形成し、上記第１挟持部材８の挟持片１１に挟まれる板状の被挟持片１８と、該被挟持片１８の上端部で水平方向に延びる板状の受け片部１９と、該受け片部１９の前後左右に張り出す縁部２０，２１とを有して、断熱部材７の上端部左右両側に、上記摺動金具６が摺動可能な摺動レール部２２を形成している。
【００２８】
この断熱部材７の詳細は、図４、図５、図６に示している。すなわち、被挟持片１８と受け片部１９とで縦断面Ｔ字形に形成して、固定金具５を構成する第１挟持部材８の挟持片１１から上の部位（上部）を、左右から嵌め付けられる形にする。被挟持片１１の中央部には、貫通孔２３を形成して、前記ボルト１４の挿通を可能にしている。
【００２９】
そして、上記受け片部１９の左右両端には、第１挟持部材８の受け片１２よりも外方へ突出するように、上記縁部２０，２１の一部である左右縁部２０を、受け片部１９と同じ厚みで形成する。また、前後の両端には、受け片１２よりも前後方向に突出させるため、上記縁部２０，２１の一部である前後縁部２１を形成する。この前後縁部２１は、上記受け片部１９よりも厚く形成する。その厚みは、受け片１２の下面位置よりも下にその下面が位置する厚みである（図６参照）。
【００３０】
このような形に形成することによって、断熱部材７の上端部の左右両側部に、上記摺動レール部２２，２２が形成できる。
【００３１】
また、この摺動レール部２２，２２の下側であって、被挟持片１８の左右両側面における前後方向両端部には、前後方向内側に向けて凸の、正面視台形状の係合凸部２４を形成している。そしてこの係合凸部２４に係合する係合凹部２５を、上記第１挟持部材８の対応位置に形成している。このことにより、固定金具５と断熱部材７は上下方向で不分離となり、一体性が高まるので、支持具１としての強度を高めることができる。
【００３２】
上記摺動金具６は、左右一対の第２挟持部材２６，２６で構成し、この挟持部材２６はその下部に、上記摺動レール部２２に左右方向から摺動可能に嵌まる断面コ字形の摺動溝部２７を有している。この摺動溝部２７は、左右方向内側に向けて開口しているもので、上記固定金具５の第１挟持部材８における受け片１２とともに、前記噛み合い構造部を構成するものである。
【００３３】
摺動金具６を構成する第２挟持部材２６は、屋根板３ａを係止するための吊子２８を挟んで保持するように形成しており、吊子２８を挟んだ時に、摺動部材６が前後方向に摺動できるように、上記摺動溝部２７における上側の接地片２７ａの幅を設定している。
【００３４】
この接地片２７ａからは、吊子２８を挟む挟持片２９を立設し、挟持片２９の上端からは、屋根板３ａを受ける受け片３０を外方に向けて折曲して形成している。上記挟持片２９も、吊子２８を固定するために締め付ける部位であり、締結具（ボルト３１ナット３２）による締結を可能とするため角孔３３を形成している。
【００３５】
また、挟持片２９の形状は、固定金具５を構成する第１挟持金具８の挟持片１１と同様に、末広がり状に形成している。このように、締結を行う部分の形を、末広がり状に形成して幅広に設定すると、締め付け強度を高くすることができる。すなわち、第１挟持部材８の場合には、下葺屋根２の馳締部２ａを、挟持片１１からら下側が開くことなく強力に締め付けることができる。また、第２挟持部材２６の場合には、挟持片２９から下側が開くことを防止して、摺動レール部２２に対しての取り付け状態を強力に維持できる。
【００３６】
なお、上記摺動溝部２７の長さは、前後方向への摺動距離の必要性に応じて、摺動レール部２２の長さを考慮して適宜設定する。また、この摺動レール部２２の前後方向の端部には、下へ折曲するストッパ３４を形成し、摺動によって摺動部材６が摺動レール部２２から脱落することを阻止している。
【００３７】
さらに、摺動金具６を構成する第２挟持部材２６における摺動溝部２７の外側面の前後方向中間位置、すなわち第２挟持部材２６を締め付けるボルト３１に対応する位置には、摺動金具６の前後方向中間位置が固定金具５の前後方向中間位置に対応したことを示すべく、目印３５を形成している（図７参照）。この形成は、刻印で行った例を示したが、塗布などその他の方法で形成するもよい。
なお、図中３６は、補強用のリブである。
【００３８】
このように構成した支持具１では、固定金具５のボルト１４ナット１５を締め付けて、下葺屋根２上に固定する。そして、摺動金具６の固定部材５上での位置を上述の目印３５を利用して、摺動金具６が前後に等距離摺動できるように設定する。必要であれば、施工時の気温、日差し等に応じて、何れか一方に偏らせることができるような目印を形成するもよい。目印３５は締め付け位置にあるボルト３１と関連付けて形成したので、位置合わせのし忘れなどを防止できる。
【００３９】
支持具１を下葺屋根２に固定した後は、摺動金具６に保持した吊子２８を利用して、屋根板３ａを順次固定し、上葺屋根３を形成する。
【００４０】
この固定状態で、上葺屋根３に温度変化が起こって伸縮すると、摺動金具６は、吊子２８を介して上葺屋根３と一体であるので、屋根板３ａの伸縮に伴って、固定金具５上を摺動する（図８参照）。この摺動により、屋根板３ａに溜まる歪を除去できるので、音鳴りを防止できる。
【００４１】
しかも、固定金具５と摺動金具６とには、断熱に必要なだけの間隔を隔てて噛み合い構造（受け片１２、摺動溝部２７）を形成しているので、断熱部材７なしでも一体の状態を維持できる。つまり、合成樹脂製の断熱部材７のみに荷重がかかることを回避して、固定金具５と摺動金具６と断熱部材７とが一体となって、荷重を支える。このため、高い強度を得られ、正圧にも負圧にも強い、支持具１となる。
【００４２】
また、噛み合い構造の間隔を狭く形成できるので、断熱部材７の形状を薄い部分の集合体で形成できる。つまり、上述のように板状の被挟持片１８と受け片部１９とを形成するので、断熱部材７の材料を少なくできる。このため、資源の有効利用が図れるとともに、万が一焼失しても、有害ガスが発生することを抑えることができる。
【００４３】
さらに、固定金具５も摺動金具６も、左右一対の挟持部材（第１挟持部材８、第２挟持部材２６）で構成しているので、固定金具５は下葺屋根２に対しての、摺動金具６は固定金具５に対しての固定作業が容易である。
【００４４】
以上の説明における下葺屋根２は、この発明の下地材に対応し、
第１挟持部材８および第２挟持部材２６は、挟持部材に対応し、
受け片１２と摺動溝部２７は、噛み合い構造に対応し、
係合凸部２４は被係合部に対応し、
係合凹部２５は係合部に対応し、
ボルト１４ナット１５は締結具に対応するも、
この発明は、上記構成のみに限定されるものではない。
【００４５】
例えば、噛み合い構造は、上述例のように摺動部材が固定部材の上部を上から抱え込むように構成するのではなく、その逆に、固定部材の上部が摺動部材の下部を下から抱え込むような形に形成するもよい。
【００４６】
また断熱部の構成も、その噛み合い構造に合わせて適宜構成すればよく、上述例のように固定金具に対して取り付けるのではなく、摺動金具に取り付けるもよく、いずれか一方に一体形成するもよい。
【００４７】
さらに、摺動金具６に代えて、摺動不可に取り付ける部材を取り付けて、音鳴り防止効果を持たない支持具を構成するもよい。
【００４８】
そのためには、例えば、図９に示したような形の吊子２８を用いると、同一形状の支持具１であっても摺動金具６を摺動しないように設定できる。この吊子２８は、下端部の前後方向両端部に、垂下片２８ａを一体に形成し、取り付けたときに、上記垂下片２８ａが断熱部材７の前後に位置するようにしている。同一の構成部位については、上述と同一の符号を付して詳しい説明を省略する。
【００４９】
図１０は、断熱部材７の他の例を示し、上面と前後縁部を覆うように、薄い金属板からなる被覆材３７を取り付けている。このように被覆材３７を取り付けると、断熱部材７の耐久性を向上できる。
【００５０】
図１１は、支持具１の斜視図であり、固定金具５の変形例を示している。この固定金具５では、左右一対の第１挟持部材８の挟持片１１から下を、略つ字状に形成して、接地片３８の先端縁から立ち上げた挟圧部３９で挟持を行うようにしている。
【００５１】
【発明の効果】
以上のようにこの発明によれば、下地材上に固定する固定金具と屋根板を支持する摺動金具とを分割形成して、固定金具の上部と摺動金具の下部に噛み合い構造を形成して、この間に形成した必要最小限の隙間に合成樹脂や合成ゴムからなる断熱部材を形成するので、合成樹脂等の使用量を極力抑えることができる。
【００５２】
このため、資源の有効利用が行え、自然環境保全にも貢献する。また、噛み合い構造を有して、合成樹脂に頼り切らない構造に構成したので、高い強度を得られるうえに、万が一焼失しても有害ガスの発生を抑制でき、また屋根が飛んでしまうような不都合をなくすこともできる。
【００５３】
また、摺動金具が前後方向に摺動可能であるので、支持した屋根板に溜まる歪を、摺動により即座に取り除くことができ、音鳴りを防止できる。
【００５４】
その摺動のため、固定金具の上部と摺動金具の下部に、熱伝導の遮断に必要な適宜間隔を隔てて相互に噛み合う噛み合い構造を形成しているが、この噛み合い構造は、断熱部材なしでも、上下方向で分離しない構造である。このため、断熱部材の厚みを所定の機能を果たす必要なだけの薄さに設定できる。つまり、この場合も、断熱部材として使用する合成樹脂等の量を極力抑えることができる。
【００５５】
したがって、上述のように、資源の有効利用に貢献できるとともに、万が一火災で焼失しても、発生する有害ガスの発生を抑えることができる。また、使用量を少なくするために噛み合い構造を設けて固定金具と摺動金具を近接させているので、不測の焼失があっても、屋根板支持具を構成する固定金具と摺動金具の一体性は失われず、屋根が飛んでしまうようなことを阻止できる。
【００５６】
さらに、上述のように固定金具と摺動金具との間に噛み合い構造を形成して、これらの間に断熱部材を介装しているので、合成樹脂製の部位のみに頼らずに、固定金具や摺動金具と協働して、正圧にも負圧にも高い強度を得ることができる。
【００５７】
特に、固定金具の上部に係合部を形成し、断熱部材の対応位置に被係合部を形成すると、固定金具と断熱部材の一体性を高め、強度をより高くすることができる。
【００５８】
さらに、摺動する摺動部材の初期位置を設定できるように、目印を、締め付けのための締結具に関連付けて設けると、摺動金具と固定金具を正しい位置関係にして固定することを促すことができ、音鳴り防止効果を確実に達成することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a roof plate support for forming a roof by supporting a metal roof plate called a folded plate, and more particularly to a roof plate support having a heat insulating portion.
[0002]
[Prior art]
The roof plate supporter fixes (supports) the roof plate after fixing it on a base material such as H steel, C type steel, an existing roof, or a lower roof. And when giving heat insulation, the roof board | substrate support tool which has the heat insulation part which interrupts | blocks the heat conduction in an up-down direction is used so that the heat | fever of the supported roof board may not be transmitted to a base material.
[0003]
This heat insulating part is formed of a synthetic resin, and is formed in various ways because of its high degree of freedom in molding.
[0004]
For example, the support tools disclosed in Japanese Patent Application Laid-Open Nos. 9-328869 and 11-141061 are examples. This support tool is composed of a saddle that is divided into two in the lateral direction to be fixed to the base material, and has a structure in which a roof plate support fitting for fixing the roof plate is held on the top of the saddle. All the saddles are made of synthetic resin. That is, the roof plate is supported by a lump of synthetic resin.
[0005]
In the support device configured as described above, it is difficult to obtain sufficient strength, and a lot of synthetic resin is used, so that there is a difficulty in effective use of resources.
[0006]
Moreover, in order to absorb the distortion which a fixed metal roof board expands and contracts by a temperature change, the said support tool enabled the support part which supports a roof board to be slidable in the expansion / contraction direction of a roof board. An inverted T-shaped groove is formed in the upper part of the saddle, and a roof plate support fitting for fixing the roof plate to the inverted T-shaped groove is slidably supported.
[0007]
However, as described above, since the saddle is a lump of synthetic resin, if it becomes a fire, everything will be burned out and the roof will fly.
[0008]
Therefore, the roof plate support of Japanese Patent No. 3019993 was devised. This roof plate supporter is mounted on a lower member fixed on a base material so that an upper member having a locking member for locking the roof plate is slidable in the length direction of the roof plate, that is, in the front-rear direction. The heat insulating member made of synthetic resin is incorporated between the upper member and the lower member. According to this roof plate support, the above-mentioned problems can be solved, but in this case as well, it tends to depend on the good moldability peculiar to the synthetic resin, and is relatively large in terms of strength and aesthetics. There was a tendency to use thermal insulation members. If the size is large, the amount of synthetic resin used will increase.
[0009]
[Problems to be solved by the invention]
Therefore, the main object of the present invention is to minimize the amount of a material for achieving a heat insulating function, that is, a synthetic resin or a synthetic rubber, and to obtain a sufficient strength.
[0010]
[Means for Solving the Problems]
For that purpose, there are a fixing bracket for fixing on the base material, a sliding bracket that supports the roof plate and is slidable in the front-rear direction, and is located between them to conduct heat conduction in the vertical direction. A roof plate support having a heat insulating member to be cut off, wherein the upper portion of the fixing bracket and the lower portion of the sliding bracket are meshed with each other at an appropriate interval necessary for blocking heat conduction, and the sliding direction A meshing structure portion that can be moved at a position, and the heat insulating member is attached between the meshing structure portions, and a plate-shaped sandwiched piece sandwiched by the fixing bracket is sandwiched between the heat insulating member and the sandwiched portion. A plate-shaped receiving piece portion extending in the horizontal direction at the upper end portion of the piece and an edge portion projecting to the front, rear, left and right of the receiving piece portion are formed, and the upper end portion of the heat insulating member is formed in the left-right direction at the lower end portion of the sliding bracket shingle support der sliding groove which is open is formed a slide rail portion slidable inward It is characterized in.
[0011]
The meshing structure meshes with each other in the vertical direction, for example, like a T-shaped rail and a groove that holds the upper part thereof, so that it cannot be separated in the vertical direction and can slide in the longitudinal direction. It is of shape. An appropriate interval necessary for blocking heat conduction is formed between them. This interval is, for example, when the heat insulating member used synthetic resins such as ABS resin, sufficient if the order of approximately 5 mm to 10 mm.
[0012]
In the roof plate support tool having such a configuration, the roof plate is supported on the sliding metal fitting fixed to the base material using the fixing metal and slidably mounted on the fixed metal fitting. In this state, when the roof plate expands and contracts due to heat, the sliding member slides in the front-rear direction following the expansion and contraction of the roof plate, and the stress accumulated on the roof plate is eliminated. Thermal support the shingle, while transmitted to the sliding bracket, since the heat insulating member to block heat conduction, not conducted to the fixed bracket.
[0013]
Further, the top and bottom of the sliding bracket fixed bracket, so to form a structure meshing engaged with each other, strength heat insulating member is interposed made of a synthetic resin or the like is high, even a negative pressure to positive pressure It can be made to withstand sufficiently. Also, any chance insulation member is even may like to destroyed by fire, it is possible to retain the integrity of the fixing bracket and the sliding bracket, it is possible to prevent the inconvenience that would fly roof. Furthermore, since the interval between the meshing structures is an interval necessary for blocking heat conduction, it can be formed into a thin and compact shape.
[0014]
The heat insulating member has a shape having a plate-shaped sandwiched piece sandwiched by the fixing bracket, a plate-shaped receiving piece, and edges formed on the front, rear, left, and right of the receiving piece, and thus can be formed in a thin shape. .
[0015]
The fixing bracket and / or the sliding bracket may be composed of a pair of left and right clamping members. When the fixing bracket is formed of a pair of left and right holding members, the sandwiched portion of the heat insulating member can be formed thinner, and when the base material is a roof, it is easy to form a fixing structure for the base material. Further, when the sliding metal fitting is formed of a pair of left and right clamping members, it is easy to attach the heat insulating member to the sliding rail portion.
[0016]
Moreover, you may form the engaging part which engages with the to-be-engaged part formed in the corresponding position of the said heat insulation member, and cannot isolate | separate in an up-down direction in the both sides of the front-back direction in the upper part of the said fixing metal fitting. When the engaging portion and the engaged portion are engaged, separation in the vertical direction becomes impossible simply by combining the fixing bracket and the heat insulating member. For this reason, integrity is increased and high strength can be obtained.
[0017]
Further, when holding a fastener for tightening in the left-right direction at an appropriate position in the front-rear direction of the fixing bracket, and when making the front-rear direction intermediate position of the sliding bracket correspond to the front-rear direction intermediate position of the fixing bracket, You may form a mark in the position corresponding to the said fastener in a sliding metal fitting. In other words, when the roofing plate support is fixed by tightening the fastener, the mark is aligned with the fastener so that the intermediate position of the sliding bracket corresponds to the intermediate position of the fixing bracket in the longitudinal direction. The metal fittings are slidable equidistantly forward and backward. When the fastener is fastened and fixed, it can be aligned with the fastener that is the work object as a reference, so that it is possible to prevent inconveniences such as misalignment and forgetting to perform the alignment.
[0018]
Another means is a roof structure using the roof plate support.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a roof plate support 1 (hereinafter referred to as a support), and this support 1 forms an upper roof 3 on a lower roof 2 as shown in FIG. Thus, it is for use in obtaining the roof 4 having heat insulation and soundproofing. And this support tool 1 carries out the heat conduction in the up-down direction on the fixed metal fitting 5 fixed to the lower roof 2 as a base material, and the sliding metal fitting 6 which supports the roof board 3a and slides in the front-back direction. It is attached and configured via a heat insulating part that blocks
[0020]
In this example, the heat insulating part is constituted by another member, that is, a heat insulating member 7 made of synthetic resin, attached to the upper part of the fixing metal 5 and interposed between the sliding metal 6.
[0021]
As shown in FIG. 3, the fixture 5 includes a pair of left and right first metal plates 8 and 8 made of a metal plate. These first clamping members 8 and 8 are fixed on the lower roof 2 by sandwiching and tightening the tightening portion 2 a of the lower roof 2.
[0022]
That is, a grounding piece 9 extending substantially horizontally is provided at the lower end, and is extended from the inner side edge of the grounding piece 9 so as to bulge out in a substantially semicircular direction outward in the left-right direction. A holding piece 11 is formed extending vertically from the upper end of the shank 10 and a receiving piece 12 is formed from the upper end of the holding piece 11 that is bent at right angles outward in the left-right direction. .
[0023]
The sliding metal fitting 6 is attached to the upper part of the fixing metal member 5 via the heat insulating member 7. The upper part of the fixing metal member 5 and the lower part of the sliding metal member 6 are appropriately provided for the purpose of blocking heat conduction. A meshing structure is formed that meshes with each other at an interval and enables movement in the sliding direction. The receiving piece 12 is one of the meshing structures.
[0024]
Further, a square hole 13 is formed in the central portion of the holding piece 11 so that a fastener for fastening the first holding members 8 and 8 to the left and right can be inserted. A bolt 14 nut 15 was used as a fastener. Further, when the receiving piece 12 is hung from the holding piece 11 and from the holding piece 11 to the thinning portion 10, a rib 16 protruding outward is formed and reinforced.
[0025]
As described above, fixing to the lower roof 2 by tightening is performed by the clamping pieces 11. For this reason, the lower side of the intermediate position in the up-and-down direction of the sandwiching piece 11 is formed so as to be wider in the front-rear direction so that the lower side is wider in the front-rear direction, so is doing.
[0026]
In the figure, 17 is a through hole through which a fixing hex is inserted.
[0027]
The heat insulating member 7 is made of synthetic resin, and has a plate-like sandwiched piece 18 sandwiched between the sandwiching pieces 11 of the first sandwiching member 8 and a plate-like member extending in the horizontal direction at the upper end of the sandwiched piece 18. A sliding piece 6 having a receiving piece portion 19 and edge portions 20 and 21 projecting to the front, rear, left and right of the receiving piece portion 19 is slidable on the left and right sides of the upper end portion of the heat insulating member 7. A rail portion 22 is formed.
[0028]
Details of the heat insulating member 7 are shown in FIGS. 4, 5, and 6. In other words, the sandwiched piece 18 and the receiving piece portion 19 are formed in a T-shaped vertical section, and the portion (upper part) above the sandwiching piece 11 of the first sandwiching member 8 constituting the fixing bracket 5 is fitted from the left and right. Shape. A through hole 23 is formed in the central portion of the sandwiched piece 11 so that the bolt 14 can be inserted.
[0029]
The left and right edge portions 20, which are part of the edge portions 20 and 21, are received at the left and right ends of the receiving piece portion 19 so as to protrude outward from the receiving piece 12 of the first holding member 8. It is formed with the same thickness as the piece 19. In addition, front and rear edge portions 21 which are part of the edge portions 20 and 21 are formed at both front and rear ends in order to protrude in the front and rear direction from the receiving piece 12. The front and rear edge portions 21 are formed thicker than the receiving piece portion 19. The thickness is the thickness at which the lower surface is located below the position of the lower surface of the receiving piece 12 (see FIG. 6).
[0030]
By forming it in such a shape, the slide rail portions 22, 22 can be formed on the left and right sides of the upper end portion of the heat insulating member 7.
[0031]
Further, on the lower side of the sliding rail portions 22 and 22 and on both left and right side surfaces of the sandwiched piece 18, the front and rear end engaging projections that are convex toward the inner side in the front and rear direction. A portion 24 is formed. An engagement recess 25 that engages with the engagement protrusion 24 is formed at a position corresponding to the first clamping member 8. As a result, the fixing bracket 5 and the heat insulating member 7 are not separated in the vertical direction, and the unity is increased, so that the strength of the support 1 can be increased.
[0032]
The sliding metal fitting 6 is composed of a pair of left and right second clamping members 26, 26, and the clamping member 26 has a U-shaped cross section that fits in the lower part of the sliding rail portion 22 so as to be slidable in the lateral direction. A sliding groove 27 is provided. The sliding groove portion 27 is opened toward the inner side in the left-right direction, and constitutes the meshing structure portion together with the receiving piece 12 in the first clamping member 8 of the fixing bracket 5.
[0033]
The second sandwiching member 26 constituting the sliding metal fitting 6 is formed so as to sandwich and hold a hanging element 28 for locking the roof plate 3a. When the hanging element 28 is sandwiched, the sliding member 6 is arranged. The width of the upper grounding piece 27a in the sliding groove 27 is set so that can slide in the front-rear direction.
[0034]
From the grounding piece 27a, a holding piece 29 is provided so as to sandwich the suspension 28, and a receiving piece 30 for receiving the roof plate 3a is bent outward from the upper end of the holding piece 29. . The clamping piece 29 is also a part to be fastened to fix the suspension 28, and is formed with a square hole 33 in order to be fastened by a fastener (bolt 31 nut 32).
[0035]
Further, the shape of the sandwiching piece 29 is formed in a widening shape like the sandwiching piece 11 of the first sandwiching metal fitting 8 constituting the fixing metal fitting 5. As described above, when the shape of the portion to be fastened is formed in a divergent shape and is set to be wide, the fastening strength can be increased. In other words, in the case of the first clamping member 8, the clamping part 2 a of the lower roof 2 can be strongly clamped without opening the lower side from the clamping piece 11. Moreover, in the case of the 2nd clamping member 26, it can prevent that a lower side opens from the clamping piece 29, and can maintain the attachment state with respect to the slide rail part 22 strongly.
[0036]
The length of the sliding groove portion 27 is appropriately set in consideration of the length of the sliding rail portion 22 according to the necessity of the sliding distance in the front-rear direction. Further, a stopper 34 that bends downward is formed at the front-rear direction end of the sliding rail portion 22 to prevent the sliding member 6 from falling off the sliding rail portion 22 due to sliding. .
[0037]
Further, at the intermediate position in the front-rear direction of the outer surface of the sliding groove portion 27 in the second clamping member 26 constituting the sliding bracket 6, that is, at the position corresponding to the bolt 31 that tightens the second clamping member 26, A mark 35 is formed to indicate that the intermediate position in the front-rear direction corresponds to the intermediate position in the front-rear direction of the fixture 5 (see FIG. 7). Although the example of this formation is shown by engraving, it may be formed by other methods such as coating.
In the figure, reference numeral 36 denotes a reinforcing rib.
[0038]
In the support device 1 configured as described above, the bolts 14 and nuts 15 of the fixing bracket 5 are tightened and fixed on the lower roof 2. And the position on the fixing member 5 of the sliding metal fitting 6 is set using the above-mentioned mark 35 so that the sliding metal fitting 6 can slide back and forth at an equal distance. If necessary, a mark that can be biased to any one of the two may be formed according to the temperature, sunlight, etc. during construction. Since the mark 35 is formed in association with the bolt 31 at the tightening position, forgetting to align can be prevented.
[0039]
After the support 1 is fixed to the lower roof 2, the upper roof 3 is formed by sequentially fixing the roof plate 3 a using the hanger 28 held by the sliding bracket 6.
[0040]
In this fixed state, when the temperature change occurs on the upper roof 3 and expands and contracts, the sliding metal fitting 6 is integrated with the upper roof 3 via the hanger 28, so that it is fixed along with the expansion and contraction of the roof plate 3 a. It slides on the metal fitting 5 (see FIG. 8). By this sliding, the distortion accumulated in the roof plate 3a can be removed, so that the noise can be prevented.
[0041]
In addition, the fixed metal fitting 5 and the sliding metal fitting 6 are formed with a meshing structure (receiving piece 12 and sliding groove 27) with an interval necessary for heat insulation. The state can be maintained. In other words, the load is applied only to the heat insulating member 7 made of synthetic resin, and the fixing bracket 5, the sliding bracket 6 and the heat insulating member 7 are integrated to support the load. For this reason, it becomes the support tool 1 which can obtain high intensity | strength and is strong also to a positive pressure and a negative pressure.
[0042]
Moreover, since the space | interval of a meshing structure can be formed narrowly, the shape of the heat insulation member 7 can be formed by the aggregate | assembly of a thin part. That is, since the plate-like sandwiched piece 18 and the receiving piece portion 19 are formed as described above, the material of the heat insulating member 7 can be reduced. For this reason, effective use of resources can be achieved, and even if it is burned out, generation of harmful gas can be suppressed.
[0043]
Furthermore, since both the fixing metal fitting 5 and the sliding metal fitting 6 are constituted by a pair of right and left holding members (first holding member 8 and second holding member 26), the fixing metal fitting 5 is attached to the lower roof 2; The sliding metal fitting 6 can be easily fixed to the fixed metal fitting 5.
[0044]
The lower roof 2 in the above description corresponds to the base material of the present invention ,
The first clamping member 8 and the second clamping member 26 correspond to the clamping member,
The receiving piece 12 and the sliding groove portion 27 correspond to the meshing structure,
The engaging convex portion 24 corresponds to the engaged portion,
The engaging recess 25 corresponds to the engaging portion,
Bolt 14 nut 15 corresponds to the fastener,
The present invention is not limited to the above configuration.
[0045]
For example, the meshing structure is not configured such that the sliding member holds the upper part of the fixing member from above as in the above example, but conversely, the upper part of the fixing member holds the lower part of the sliding member from below. It may be formed into any shape.
[0046]
In addition, the structure of the heat insulating portion may be appropriately configured in accordance with the meshing structure, and it may be attached to the sliding metal fitting instead of being attached to the fixing metal fitting as in the above example, or may be integrally formed on either one. Good.
[0047]
Further, instead of the sliding metal fitting 6, a non-sliding member may be attached to constitute a support that does not have a noise-preventing effect.
[0048]
For that purpose, for example, when the hanging element 28 having a shape as shown in FIG. 9 is used, the sliding fitting 6 can be set not to slide even if the supporting tool 1 has the same shape. The hanging piece 28 is formed such that a hanging piece 28 a is integrally formed at both ends in the front-rear direction of the lower end portion, and the hanging piece 28 a is positioned before and after the heat insulating member 7 when attached. About the same component, the same code | symbol as the above-mentioned is attached | subjected, and detailed description is abbreviate | omitted.
[0049]
FIG. 10 shows another example of the heat insulating member 7, and a covering material 37 made of a thin metal plate is attached so as to cover the upper surface and the front and rear edges. When the covering material 37 is attached in this way, the durability of the heat insulating member 7 can be improved.
[0050]
FIG. 11 is a perspective view of the support 1 and shows a modification of the fixture 5. In this fixing bracket 5, the lower part of the pair of left and right first clamping members 8 is formed in a substantially square shape from below the clamping piece 11, and is clamped by a clamping part 39 raised from the tip edge of the grounding piece 38. I have to.
[0051]
【The invention's effect】
As described above, according to the present invention, the fixing bracket for fixing on the base material and the sliding bracket for supporting the roof plate are separately formed, and the meshing structure is formed at the upper portion of the fixing bracket and the lower portion of the sliding bracket. In addition, since the heat insulating member made of synthetic resin or synthetic rubber is formed in the minimum necessary gap formed in the meantime, the amount of synthetic resin used can be suppressed as much as possible.
[0052]
For this reason, resources can be used effectively and contribute to the conservation of the natural environment. In addition, since it has a meshing structure and is structured so as not to rely on synthetic resin, it can obtain high strength, and even if it burns out, it can suppress the generation of harmful gases and the roof will fly away. Inconvenience can be eliminated.
[0053]
Further , since the sliding bracket can slide in the front-rear direction, the distortion accumulated on the supported roof plate can be immediately removed by sliding, and noise can be prevented.
[0054]
Because of its sliding under the upper sliding bracket fixed bracket, but to form a mesh structure meshed with each other at a suitable interval required interruption of heat conduction, the mating structure, no heat insulating member However, the structure does not separate in the vertical direction. For this reason , the thickness of the heat insulating member can be set as thin as necessary to fulfill a predetermined function. That is, also in this case , the amount of the synthetic resin used as the heat insulating member can be suppressed as much as possible.
[0055]
Therefore, as described above, it is possible to contribute to the effective use of resources, and even if it is burnt down by a fire, generation of harmful gases can be suppressed. In order to reduce the amount of use, an interlocking structure is provided so that the fixing bracket and the sliding bracket are close to each other. Sex is not lost, and it can prevent the roof from flying.
[0056]
Further, by forming a mesh structure between the fixing bracket and the sliding bracket as described above, since the interposed adiabatic member between them, without relying only on the site of the synthetic resin, fixed and fitting and sliding bracket cooperating, it is possible to obtain a high strength even under negative pressure to positive pressure.
[0057]
In particular, the engagement portion is formed in the upper portion of the fixing bracket and forms a engaged portion in the corresponding position of the heat insulating member, enhancing the integrity of the fixing member and the heat insulating member, it is possible to further increase the strength.
[0058]
Furthermore, if a mark is provided in association with the fastener for tightening so that the initial position of the sliding member that slides can be set, it is urged to fix the sliding bracket and the fixing bracket in the correct positional relationship. Therefore, it is possible to reliably achieve the effect of preventing sound generation.
