Description

【０００１】
【発明の属する技術分野】
この発明は、折板と称する金属製の屋根板を取り付けるための屋根板支持具に関し、より詳しくは、屋根板にかかる歪を吸収できるような屋根板支持具に関する。
【０００２】
【従来の技術】
上述のような支持具として、下側に形成した下葺屋根の上に固定する下部材と、上側に形成する上葺屋根を支持するための係止部材固定用の上部材とを設け、該上部材を、屋根の長さ方向に沿って摺動するように上記下部材上に載置するとともに、これらを上下方向で分離不可にする連結手段で連結し、上部材と下部材との間に合成樹脂製の断熱部材を組み込んだものを提案した（特許文献１参照）。
【０００３】
この支持具は、上葺屋根を取り付ける係止部材が上部材とともに下部材上を屋根の長さ方向（前後方向）に摺動する。このため、上葺屋根が熱によって伸縮しても、その伸縮によって掛かる歪を吸収でき、突然の音鳴りを防止できるので、高い需要がある。
【０００４】
しかも、上記上部材と下部材のうちの少なくとも一方を金属で形成することによって、合成樹脂のみで構成する場合に比して高い固定強度や耐久性を得ることができる利点も有する。
【０００５】
しかし、金属からなる部材と合成樹脂からなる部材を、高強度化等の高性能化を追求しつつ、摺動可能な状態で組み合わせるには、まだ改良の余地があった。
【０００６】
【特許文献１】
特許第３０１９９９３号公報。
【０００７】
【発明が解決しようとする課題】
そこでこの発明は、より高性能な屋根板支持具を得ることを主たる課題とする。
【０００８】
【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金属製の固定金具と、該固定金具の上に取り付けられて上下方向での熱伝導を遮断する断熱部材と、該断熱部材に対して前後方向に摺動可能に取り付けられて屋根板を直接あるいは間接的に支持する金属製の摺動金具とを有する屋根板支持具であって、上記断熱部材に、上面に開口部を有するとともに内部において左右方向に広がる抜け止め部を有した摺動溝を形成し、上記摺動金具の下部には、上記摺動溝の開口部間を摺動する垂直部と、上記抜け止め部内を摺動する抜け止め片とを有する摺動部を形成した屋根板支持具であることを特徴とする。
【０００９】
上記摺動金具に対して直接、あるいは吊子等の係止部材を介して間接的に取り付けた屋根板が、熱により伸縮すると、摺動金具の摺動部は、断熱部材に形成した摺動溝内を屋根板の長さ方向に、屋根板に溜まる歪を取り除くように、屋根板の伸縮に追従して摺動する。
【００１０】
このとき、摺動金具の摺動部には左右方向に張り出す抜け止め片を形成しているので、抜け止め片が摺動溝の抜け止め部に引っかかり、上下方向での確実な抜け止め作用が得られる。同時に抜け止め片は、摺動溝の抜け止め部によって摺動金具を所望の正しい姿勢にすべく規制される上に、上記垂直部も同様に、摺動溝の開口部によって規制され、この状態で屋根板の伸縮に追従した摺動がなされる。
【００１１】
なお、前記固定金具を、左右一対の挟持部材を用いて構成し、該挟持部材の上端部には、前記断熱部材に対して左右方向から嵌合して上下方向で不分離とする、例えばコ字形などの嵌合部を形成し、該嵌合部の上端部を、前記摺動部材の摺動部と上下方向でオーバーラップする長さに設定するとよい。
【００１２】
また、固定金具を上記のように構成した場合には、前記断熱部材の上端部に、前記挟持部材の上端を押さえる規制部を形成するとよい。換言すれば、上記上端部にを差し込む袋状の差込部を形成するとよい。
【００１３】
【発明の効果】
以上のように、この発明によれば、屋根板を直接あるいは間接的に取り付けた摺動金具は、屋根板が熱により伸縮するときに、その伸縮に伴って断熱部材上を摺動する。このため、屋根板に歪が溜まることを阻止でき、音鳴り防止をすることができる。
【００１４】
しかもその摺動は、摺動金具の垂直部と抜け止め片とが摺動溝内で規制され、支えられた状態で行われるので、安定した円滑な摺動が期待でき、歪吸収効果は確実である。
【００１５】
またそのための構成は、固定金具と断熱部材と摺動部材の三種類からなるので、簡素である。組み立ての手間も、部品の管理も簡単で、また簡素な構造ゆえに、コストを抑えることもできる。
【００１６】
そのうえ、下地材に対しての固定を行う固定金具は金属製であるので、合成樹脂の場合とは異なり、きつく締めても割れなどが発生しにくい。このため、高い強度を得ることができる。
【００１７】
さらに摺動金具も金属製で、しかも吊子などのような薄い金属板ではなく、必要十分な厚み（強度）を有する金属板で形成できる。そしてこの摺動金具に摺動部を形成しているので、上方への引っ張りに対して高い耐久性を得ることができる。
【００１８】
また断熱部材は、少なくとも摺動溝の外側に断熱に必要な所定の厚みを形成すればよく、材料、すなわち合成樹脂の使用量を極力抑えることができる。このため、コストの低減を図ることができるとともに、万が一火災で燃えた場合でも、有害ガスの発生量を少なくすることができる。
【００１９】
固定金具の嵌合部の上端部を、嵌合部が嵌合する断熱部材内に位置する摺動部材の摺動部と上下方向でオーバーラップする構成を採用すると、万が一火災で断熱部材が燃えたとしても、上記上端部と摺動部が上下方向で引っかかるので、固定金具と摺動金具が分離することを抑止できる。このため、屋根が飛んでしまうような不都合を回避できる。
【００２０】
さらに断熱部材の上端部に、挟持部材の上端を押さえる規制部を形成すると、その規制部が挟持部材の嵌合部が上方へ動くのを防止するので、断熱部材に対して左右方向から嵌合して結合する以外にも上下方向で結合が行えることになり、固定強度を高めることができる。
【００２１】
【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）を用いて形成した屋根構造を示し、このように下葺屋根２の上に断熱材３を敷き込んで介在させてから上葺屋根４を取り付ける場合に使用する。屋根は、上述のように断熱材３を介装しているので断熱性を有するが、この性能を確実なものとすべく、支持具１も上下方向で断熱性を有するように構成している。この断熱は、下地材の上に固定する金属製の固定金具５と、屋根板４ａを支持する金属製の摺動金具６との間に合成樹脂製の断熱部材７を介装して行うが、上葺屋根４が熱によって伸縮したときにその伸縮に追従して歪を吸収するように、上記摺動金具６を屋根の長さ方向（前後方向）に摺動可能に構成している。
【００２２】
まず、支持具１の構成を説明する。
図２は、屋根板４ａを係止する係止部材としての吊子８を取り付けた状態の支持具１の斜視図、図３は作用状態を示す、吊子８のない状態の斜視図、図４は、分解斜視図である。
【００２３】
このように支持具１は、下部に位置する上記固定金具５と、上部に位置して吊子８を取り付ける上記摺動金具６と、これらの間に介装する上記断熱部材７とからなる。
【００２４】
なお、図１の例では吊子８として、いわゆる角ハゼを用いた例を示す。
【００２５】
上記固定金具５は金属板で形成し、左右一対の挟持金具（第１挟持金具９、第２挟持金具１０）と、これらに沿わせる２枚の補助金具（第１補助金具１１、第２補助金具１２）とからなる。
【００２６】
上記第１挟持金具９と第２挟持金具１０は、下葺屋根２上端の馳締め部２ａに固定するため、垂直な挟圧片９ａ，１０ａを有するとともに、下端には、下葺屋根２の上端面に設置する接地片９ｂ，１０ｂを設けている。また挟圧片９ａ，１０ａの上端には、上記断熱部材７との一体化を図るべく、組み付けるための嵌合部９ｃ，１０ｃを連設した構成である。嵌合部９ｃ，１０ｃは、前後方向に適宜長さに形成し、その断面形状はコ字形である。すなわち、断熱部材７を左右方向で挟み込むとともに、上下方向での結合状態を保持する。
【００２７】
なお、支持具１は上述のように角ハゼ用であるので、第１挟持金具９は、接地片９ｂの上方に下葺屋根２の馳締め部２ａを収容するぬすみ部９ｄを形成すべく、階段状に形成し、第２挟持金具１０は、上記ぬすみ部９ｄに対向する部位も垂直な挟圧片１０ａで形成している。
【００２８】
上記第１補助金具１１は、図５に示したように、第２挟持金具１０の内側に挟み込まれるもので、垂直な挟圧片７ａを有するとともに、この挟圧片１１ａの下端から下葺屋根２の馳締め部２ａを包み込む、略「つ」字状の係合部１１ｂを連設している。
【００２９】
上記第２補助金具１２は、第２挟持金具１０の外側面に重合するもので、同じく垂直な挟圧片１２ａを有するとともに、下端には、第２挟持金具１０の挟圧片１０ａの下端部に形成した貫通孔１０ｄを通って第１補助金具１１の係合部１１ｂと対向する係合爪１２ｂを連設している。
【００３０】
各部材９，１０，１１，１２の挟圧片９ａ，１０ａ，１１ａ，１２ａにおけるそれぞに対応する位置には、挿通孔９ｅ，１０ｅ，１１ｃ，１２ｃを形成して、ボルト１３ナット１４で挟持できるようにしている。
【００３１】
上記断熱部材７は、直方体ブロックの下面に、垂直な板を垂設した形状で、該垂直な板は、上記第１挟持金具９と第１補助金具１１とに挟まれる被挟持片１５である。被挟持片１５には、上記ボルト１３を挿通するための挿通孔１５ａを形成している。また上記ブロックの前後方向の長さは、上記嵌合部９ｃ，１０ｃの前後方向の長さよりも長く設定している。
【００３２】
上記第１挟持金具９と第２挟持金具１０嵌合部９ｃ，１０ｃが嵌合する被嵌合部１６は左右両側部に形成する。この被嵌合部１６は、上記嵌合部９ｃ，１０ｃが入り込む凹状に形成している。換言すれば、前後の両端部に縁を形成し、前後方向での位置決めが行えるようにしている。
【００３３】
そして、左右方向の中間部とその近傍には、前後方向に貫通する摺動溝１７を形成している。摺動溝１７は、上面に開口する開口部１７ａと、内部において左右両側に広がる抜け止め部１７ｂ，１７ｂとからなる。該抜け止め部１７ｂは、外側ほど上がるように傾斜させて、抜け止め力を強化している。
【００３４】
断熱部材７は、左右に分割して形成するもよいが、図示したようにひとつの部材で形成すると、強度が高いうえに部品点数が少なくなるので、コストや組み立て性の上で都合がよい。
【００３５】
上記摺動金具６は、金属板で形成し、左右一対の重合部材（第１重合部材１８、第２重合部材１９）で構成している。なお、その板厚は、吊子８の場合よりも厚く設定している。各重合部材１８，１９ともに、上記摺動溝１７の開口部１７ａ間を摺動可能な垂直部を、重合時に得られる垂直片１８ａ，１９ａを有し、下端からは、相反する方向に斜め上へ向けて傾斜する抜け止め片１８ｂ，１９ｂを連設している。上記垂直片１８ａ，１９ａの下部と抜け止め片１８ｂ，１９ｂが摺動溝１７内を摺動する摺動部６ａである。
【００３６】
なお、摺動部６ａの前後方向の長さは、断熱部材７の長さよりも長く形成して、断熱部材７上で所望量の摺動が行えるように設定している。
【００３７】
上述の如くこの例には吊子８として角ハゼ用のものを示しているが、角ハゼの吊子は、屋根板４ａを支持するときに摺動金具６に対して着脱を行わなければならないため、第１重合金具１８は垂直片１８ａの上には何も形成しないが、第２重合金具１９の上端には、第１重合金具１８側に折れて、支持する屋根板４ａを受ける受け片１９ｃを連設している。これら第１重合金具１８と第２重合金具１９の一体化のためと、吊子８を取り付けるために、上記第１重合金具１８の垂直片１８ａの上部には挿通孔１８ｃを、第２重合金具１９の垂直片１９ａの上部にはねじ孔１９ｄを形成して、第１重合金具１８側からボルト２０を螺合して保持する。
【００３８】
なお、高い一体性を得るため、各重合金具１８，１９の前後両端部側には、図６に示したように相互に嵌まり合う凹部２１または凸部２２を形成している。
【００３９】
また、上記抜け止め片１８ｂ，１９ｂの前後両端には、断熱部材７からの脱落を防止する抜け止め用のストッパ２３を、下方へ折り曲げた折り曲げ片で形成している。
【００４０】
さらに、上記抜け止め片１８ｂ，１９ｂの左右方向の長さは、上記固定金具５の嵌合部９ｃ，１０ｃとの関係において、次のように設定している。すなわち、嵌合部９ｃ，１０ｃの上端部と抜け止め片１８ｂ，１９ｂとが上下方向でオーバーラップする長さに設定する。
【００４１】
摺動金具６を断熱部材７に対して組み付けるには、断熱部材７の摺動溝１７に対して前後方向から差し込む必要があるが、図示したように、第１重合金具１８では前端に、第２重合金具１９では後端にと、相反する側にそれぞれ形成するとよい。
【００４２】
各重合金具１８，１９を前方あるいは後方から差し込んで摺動溝１７内に保持した後、重合して、凹部２１と凸部２２およびボルト２０で重合状態を保持する。
【００４３】
なお、各重合金具１８，１９をあらかじめ重合しておいても、摺動溝１７内に取り付けることができる。すなわち、差込側に、図７に示したように、折り曲げない状態のストッパ２３を形成しておき、差し込んだ後で、折り曲げて所定のストッパ形状にするとよい。
【００４４】
以下、上述のように構成した支持具１の作用効果を説明する。
下葺屋根２に対する固定は、固定金具５のボルト１３ナット１４を緩めてから、下葺屋根２の馳締め部２ａを左右に挟むように設置して、ボルト１３ナット１４を締めて行う。そして、摺動金具６の長さ方向の中間部を断熱部材７に合わせて、前後いずれの方向にも等しく摺動できるようにしてから、屋根板４ａを順に乗せつつ、吊子８の上端部を屋根板４ａ上端の馳締め部に係止して、同時に摺動金具６のボルト２０と、当て板２４、ナット２５を用いて支持具１に固定する。
【００４５】
上葺屋根４が完成すると、屋根板４ａが伸縮しても、その伸縮に追従して摺動金具６が断熱部材７上を摺動する。このため、屋根板４ａに溜まる歪を吸収して、音鳴りを防止することができる。
【００４６】
またその摺動に際しては、断熱部材７の摺動溝１７が上述のように開口部１７ａと抜け止め部１７ｂとを有する形状であって、摺動金具６の摺動部６ａが垂直部（垂直片１８ａ，１９ａ）と抜け止め片１８ｂ，１９ｂとを有する形状であるので、摺動金具６の摺動は、主に垂直部と抜け止め片１８ｂ，１９ｂとの３箇所で規制されているので、左右方向にも上下方向にもぶれないで、安定した円滑な摺動が行える。特に抜け止め片１８ｂ，１９ｂの存在により、確実な抜け止めが行え、負圧に対しても正圧に対しても強度の高い支持具１となる。
【００４７】
またそのための構成は、固定金具５と断熱部材７と摺動部材６の三種類からなるので、簡素であって、組み立ての手間も、部品の管理も簡単である。
【００４８】
そのうえ、下葺屋根に対しての固定を行う固定金具は金属製であるので、合成樹脂製の場合とは異なり、きつく締めても割れなどが発生しにくい。このため、高い強度を得ることができる。
【００４９】
同様に摺動金具６も金属製で、しかも吊子８などのような薄い金属板ではなく、必要十分な厚みを有する金属板で形成しており、剛性が高いうえに、この摺動金具６に摺動部６ａを形成しているので、上方への引っ張りに対して高い耐久性を得ることができる。
【００５０】
また断熱部材７は、少なくとも摺動溝１７の外側に断熱に必要な所定の厚みを形成すればよく、材料、すなわち合成樹脂の使用量を極力抑えることができる。このため、コストの低減を図ることができるとともに、万が一火災で燃えた場合でも、有害ガスの発生量を少なくすることができる。
【００５１】
さらに、固定金具５の嵌合部９ｃ，１０ｃの上端部と摺動部材６の抜け止め片１８ｂとを上下方向でオーバーラップさせているので、万が一火災で断熱部材７が燃えたとしても、上記上端部と摺動部６ａが上下方向で引っかかり、固定金具５と摺動金具６とは上下方向で分離しない。このため、屋根が飛んでしまうような不都合を回避できる。
【００５２】
以下に、他の例を説明する。なお、上述の構成と同一または類似する部分には上述の例と同一の符号を付して詳しい説明を省略する。
【００５３】
上記各部材はすべて必要なのではなく、例えば図８に示したように、第２補助金具１２を省略しても、十分な固定強度を得ることができる。
【００５４】
また吊子８には、強度を高めるため、適宜工夫を施すとよく、図９に示したように、下端から水平に伸ばした延設部８ａの端部に二重折り部８ｂを形成して、吊子８全体の剛性を高めたり、図１０に示したように二重折り部８ｂを挿通孔８ｃ部分にまで形成して、より一層の増強を行ったりするもよい。
【００５５】
さらに図１１に示したように、吊子８を取り付けるためのボルト２０を、上方に向けて取り付けるもよい。すなわち、この場合には、摺動金具６を構成する第１重合金具１８の上端に屋根板４ａを受ける受け片１８ｄを形成し、第２重合金具１９の上端にも、同様の受け片１９ｃを形成する。第２重合金具１９の受け片１９ｃは、第１重合金具１８の受け片１８ｄよりも低い位置に形成し、この受け片１９ｃに、ねじ孔を形成して上記ボルト２０を下から螺合して固定する。ボルト２０の頭部はカシメて止めてもよい。
【００５６】
第１重合金具１８と第２重合金具１９は、リベット２６等の適宜手段であらかじめ固定しておく。破線で示したように、図６で説明したような凸部２１と凹部２２も併せて形成するもよい。
【００５７】
この支持具１の場合、吊子の下端に形成する延設部８ａの先端には、図示したように下へ屈曲する係止片８ｃを形成して、第２重合金具１９の受け片１９ｃの端に係止するようにするとよい。係止片８ｃが受け片１９ｃの端に係止するので、負圧を受けて吊子８が上へ引っ張られても、その力に対抗する力を生むことができ、強度を高められる。
【００５８】
図１２は、吊子８に丸ハゼタイプのものを用いた支持具１の使用状態を示している。図１３がその支持具１の分解斜視図、図１４が断面図である。
【００５９】
丸ハゼの吊子８では、角ハゼの吊子８とは異なり、屋根板４ａの支持に際していちいち着脱する必要がないので、摺動金具６は、略同形の左右一対の第１重合金具１８と第２重合金具１９で構成し、これらの間に吊子８を挟み込めばよい。吊子固定用のボルト２０を挿通する挿通孔１８ｃ，１９ｅは単なる角孔でよく、先の例のようにねじを切る必要はない。
【００６０】
また、固定金具５も左右一対の第１挟持金具９と第２挟持金具１０を基本として適宜の構成を採用すればよい。図中２７は、締め付けのための補助金具である。
【００６１】
図１５は、丸ハゼタイプの固定金具５の他の例を示している。この場合には、左右一対の第１挟持金具９と第２挟持金具１０のみで構成している。
【００６２】
図１６は、左右一対の第１挟持金具９と第２挟持金具１０が断熱部材７に対して左右方向から嵌合して結合する以外にも上下方向で更なる結合が行えて固定強度を高めることができるようにした例である。すなわち、図１７にも示したように断熱部材７の上端を蓋のように覆う規制部２８を形成し、この規制部２８の下に、各挟持部材９，１０の嵌合部９ｃ，１０ｃの上端部を差し込む隙間（差込溝）を形成している。この規制部２８は、断熱部材７の上面全体に形成せずとも、例えば図１８に示したように、各挟持金具９，１０の嵌合部９ｃ，１０ｃの外側部位に対応する位置だけに形成するもよい。
【００６３】
以上のほかさらに、摺動金具６の摺動部６ａにおける抜け止め片１８ｂ，１９ｂは、例えば水平に形成するなど適宜の形状に形成するもよく、図１９に例示したように、抜け止め片の先端に上へ向く折り曲げ縁１８ｆ，１９ｆを形成して、摺動部６ａの剛性を高め、安定性を向上するもよい。
【００６４】
また角ハゼの吊子８を用いても、摺動金具６を図２０に示すように構成することで、吊子８を左右方向の中心に位置させることができる。すなわち、摺動金具６を、受け片１８ｄを有する第１重合金具１８と、摺動部６ａに対応する程度の低い高さに形成して、受け片を持たない第２重合金具１９とで構成し、これらはあらかじめ、吊子８を構成する板材と同厚のスペーサ２９を介して相互に重合し、リベット２６等の適宜手段で一体化しておく。そして第１重合金具１８の垂直片１８ａには、ボルト２０を取り付けておいたり、図示したようにボルト２０を取り付けられるようにしたりする。そして、吊子８には、下端に、水平方向に延びる延設部８ａを形成するとともに、この吊子の外側面に当てる当て板２４の上端には、屋根板４ａを受ける受け片２４ａを形成している。そして、ボルト２０ナット２５を用いて吊子８と当て板２４を取り付けたときに、吊子８の延設部８ａが第２重合金具１９の上端に当接し、当て板２４の下端が吊子８の延設部８ａに当接するように寸法を設定しておく。
【００６５】
このように構成すると、角ハゼ８の吊子と丸ハゼの吊子８をいずれも使用することができるようになる。
【００６６】
図２１に示したように、摺動金具６を一枚の金属板を折曲して「エ」字状に形成して、左右方向の中間に吊子を差し込む差込溝を形成しても同様に、角ハゼと丸ハゼのいずれも使用できるようにすることができる。
【００６７】
また、第１挟持金具９と第２挟持金具１０の嵌合部９ｃ，１０ｃは、前述のようにコ字形ではなく、図２２に示すような形に形成して強度を高めるもよい。すなわち、基本的にはコ字形であるが、嵌合部９ｃ，１０ｃの上端部を形成する基部に、垂直に立ち上がる一体の折り返し部９ｆ，１０ｆを形成して剛性を高めている。
【００６８】
特に、断熱部材７が規制部２８を有した構造である場合、図２３に示したように上記折り返し部９ｆ，１０ｆが規制部２８の端面に当接するように設定するとよい。上述の如く剛性が高い嵌合部９ｃ，１０ｃと断熱部材７との対向部位に作用反作用の力が働くが、この荷重を多数の対向面によって良好に受けることができ、支持具１としての強度をより一層高めることができる。
【００６９】
以上の構成はこの発明の一実施の形態であって、
下葺屋根２はこの発明の下地材に対応し、
第１挟持金具９と第２挟持金具１０は、左右一対の挟持金具に対応し、
垂直片１８ａ，１９ａはこの発明の垂直部に対応するも、
この発明は上記構成のみに限定されるものではない。
【００７０】
例えば、上記摺動溝の抜け止め部の形成は、開口部の垂下位置から左右いずれか一方のみに広がる形状であるもよく、また抜け止め部が左右両側に広がる形状である場合には、上記摺動金具の摺動部は、左右いずれか一方の抜け止め部のみを摺動する形状に形成するもよい。
【００７１】
また、摺動金具に屋根板４ａ係止用の部位を設けて、屋根板４ａの支持を直接摺動金具に行うようにするもよい。

As the support as described above, a lower member to be fixed on a lower roof formed on the lower side, and an upper member for fixing a locking member for supporting the upper roof formed on the upper side are provided. The upper member is placed on the lower member so as to slide along the length direction of the roof, and the upper member and the lower member are connected by a connecting means that makes them inseparable in the vertical direction. (See Patent Document 1).
[0003]
In this support, the locking member for attaching the top roof slides on the lower member together with the upper member in the length direction of the roof (front-back direction). For this reason, even if the roofing roof expands and contracts due to heat, the distortion applied by the expansion and contraction can be absorbed and sudden noise can be prevented, so there is a high demand.
[0004]
Moreover, by forming at least one of the upper member and the lower member with a metal, there is also an advantage that a higher fixing strength and durability can be obtained as compared with a case where only the synthetic resin is used.
[0005]
However, there is still room for improvement in combining a metal member and a synthetic resin member in a slidable state while pursuing high performance such as high strength.
[0006]

Japanese Patent No. 3019993.
[0007]
[Problems to be solved by the invention]
Then, this invention makes it a main subject to obtain a higher performance roofing plate support.
[0008]
[Means for Solving the Problems]
Means for that are a metal fixing bracket fixed on the base material, a heat insulating member attached on the fixing metal to block heat conduction in the vertical direction, and a front and rear direction with respect to the heat insulating member. A metal sliding fitting slidably mounted to directly or indirectly support the roof shingle, wherein the heat insulating member has an opening on the top surface and has a horizontal direction inside. A sliding groove having a retaining portion that spreads out is formed, and a vertical portion that slides between openings of the sliding groove and a retaining portion that slides in the retaining portion are formed at a lower portion of the sliding bracket. It is a roofing plate support provided with a sliding portion having a piece.
[0009]
When the roof plate directly or indirectly attached to the above-mentioned slide fitting or indirectly via a locking member such as a hanger expands and contracts due to heat, the sliding portion of the slide fitting becomes a sliding member formed on the heat insulating member. It slides in the groove along the length of the shingle, following the expansion and contraction of the shingle, so as to remove the strain accumulated on the shingle.
[0010]
At this time, since a retaining piece that protrudes in the left and right direction is formed on the sliding portion of the sliding bracket, the retaining piece is caught by the retaining portion of the sliding groove, and a reliable retaining action in the vertical direction. Is obtained. At the same time, the retaining piece is regulated by the retaining portion of the sliding groove so as to bring the sliding fitting into a desired correct posture, and the vertical portion is similarly regulated by the opening of the sliding groove. As a result, sliding is performed following the expansion and contraction of the shingle.
[0011]
The fixing bracket is constituted by using a pair of left and right holding members, and the upper end of the holding member is fitted to the heat insulating member from the left and right directions to be inseparable in the vertical direction, for example, It is preferable to form a fitting portion such as a letter shape, and set the upper end of the fitting portion to a length that vertically overlaps the sliding portion of the sliding member.
[0012]
In the case where the fixing bracket is configured as described above, it is preferable to form a restricting portion that presses the upper end of the holding member at the upper end of the heat insulating member. In other words, it is preferable to form a bag-shaped insertion portion for inserting the upper end portion.
[0013]
【The invention's effect】
As described above, according to the present invention, when the roofing plate is directly or indirectly attached to the sliding plate, when the roofing plate expands and contracts due to heat, it slides on the heat insulating member with the expansion and contraction. For this reason, it is possible to prevent distortion from accumulating on the roof shingle and to prevent noise.
[0014]
Moreover, since the sliding is performed with the vertical part of the sliding bracket and the retaining piece being regulated and supported in the sliding groove, stable and smooth sliding can be expected, and the strain absorbing effect is ensured. It is.
[0015]
Further, the configuration for this is simple because it is composed of three types of fixing bracket, heat insulating member, and sliding member. It is easy to assemble and manage parts, and the simple structure can reduce costs.
[0016]
In addition, since the metal fittings for fixing to the base material are made of metal, unlike a synthetic resin, cracks and the like hardly occur even when tightened tightly. Therefore, high strength can be obtained.
[0017]
Further, the sliding fitting is made of metal, and can be formed of a metal plate having a necessary and sufficient thickness (strength) instead of a thin metal plate such as a hook. Since the sliding portion is formed with the sliding portion, high durability against upward pulling can be obtained.
[0018]
Further, the heat insulating member may have a predetermined thickness necessary for heat insulation at least outside the sliding groove, and the amount of the material, that is, the amount of the synthetic resin used can be suppressed as much as possible. Therefore, it is possible to reduce the cost and to reduce the amount of harmful gas generated even in the event of burning by fire.
[0019]
If a configuration is adopted in which the upper end of the fitting part of the fixing bracket vertically overlaps the sliding part of the sliding member located in the heat insulating member to which the fitting part fits, the heat insulating member may be burned by fire. Even if the upper end portion and the sliding portion are hooked in the vertical direction, separation of the fixing bracket and the sliding bracket can be suppressed. For this reason, the inconvenience of the roof flying can be avoided.
[0020]
Further, when a restricting portion for pressing the upper end of the holding member is formed at the upper end of the heat insulating member, the restricting portion prevents the fitting portion of the holding member from moving upward. In addition to the joining, the joining can be performed in the vertical direction, and the fixing strength can be increased.
[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a roof structure formed by using a shingle support 1 (hereinafter referred to as a support). In this manner, a heat insulating material 3 is laid on a lower roof 2 and interposed therebetween, and then an upper roof 4 is used when attaching. The roof has heat insulating property because the heat insulating material 3 is interposed as described above, but in order to ensure this performance, the support 1 is also configured to have heat insulating property in the vertical direction. . This heat insulation is performed by interposing a synthetic resin heat insulating member 7 between a metal fixing metal member 5 fixed on the base material and a metal sliding metal member 6 supporting the roof plate 4a. The sliding bracket 6 is configured to be slidable in the length direction of the roof (front-rear direction) so that when the roof 4 expands and contracts due to heat, it absorbs the distortion following the expansion and contraction.
[0022]
First, the configuration of the support 1 will be described.
FIG. 2 is a perspective view of the support 1 with a hanging member 8 as a locking member for locking the roof plate 4a attached thereto, and FIG. 3 is a perspective view showing an operation state without the hanging member 8, and FIG. 4 is an exploded perspective view.
[0023]
As described above, the support 1 is composed of the fixing metal 5 located at the lower part, the sliding metal fitting 6 at the upper part to which the suspension 8 is attached, and the heat insulating member 7 interposed therebetween.
[0024]
In the example of FIG. 1, an example in which a so-called square goby is used as the suspension 8 is shown.
[0025]
The fixing bracket 5 is formed of a metal plate, and includes a pair of left and right holding metal fittings (a first holding metal fitting 9 and a second holding metal fitting 10) and two auxiliary metal fittings (a first auxiliary metal fitting 11 and a second auxiliary metal fitting). Metal fittings 12).
[0026]
The first holding member 9 and the second holding member 10 have vertical pressing pieces 9a and 10a in order to be fixed to the fastening portion 2a at the upper end of the roofing roof 2, and have the lower end of the roofing roof 2 at the lower end. Grounding pieces 9b and 10b are provided on the upper end face. In addition, fitting portions 9c and 10c are provided at the upper ends of the pressing pieces 9a and 10a in order to integrate with the heat insulating member 7. The fitting portions 9c and 10c are formed to have an appropriate length in the front-rear direction, and have a U-shaped cross section. That is, the heat insulating member 7 is sandwiched in the left-right direction, and the coupled state in the up-down direction is maintained.
[0027]
In addition, since the support tool 1 is for a square goby as described above, the first holding metal fitting 9 is formed above the grounding piece 9b so as to form a slack portion 9d for accommodating the tightening portion 2a of the roofing roof 2. The second holding member 10 is formed in a step shape, and a portion opposing the sunk portion 9d is also formed of a vertical pressing piece 10a.
[0028]
As shown in FIG. 5, the first auxiliary metal fitting 11 is sandwiched inside the second holding metal fitting 10, has a vertical pressing piece 7a, and has a roofing roof from the lower end of the pressing piece 11a. A substantially "T" -shaped engaging portion 11b that surrounds the second fastening portion 2a is continuously provided.
[0029]
The second auxiliary metal fitting 12 is superposed on the outer side surface of the second holding metal fitting 10, has a vertical pressing piece 12 a, and has a lower end at the lower end of the pressing piece 10 a of the second holding metal fitting 10. An engaging claw 12b facing the engaging portion 11b of the first auxiliary metal fitting 11 is continuously provided through the through hole 10d formed in the first auxiliary metal fitting 11.
[0030]
Insertion holes 9e, 10e, 11c, 12c are formed at positions corresponding to the respective pressing pieces 9a, 10a, 11a, 12a of the members 9, 10, 11, 12 and are held by bolts 13 and nuts 14. I can do it.
[0031]
The heat insulating member 7 has a shape in which a vertical plate is suspended from the lower surface of a rectangular parallelepiped block, and the vertical plate is a held piece 15 that is held between the first holding metal 9 and the first auxiliary metal 11. . An insertion hole 15 a for inserting the bolt 13 is formed in the held piece 15. The length of the block in the front-rear direction is set longer than the length of the fitting portions 9c and 10c in the front-rear direction.
[0032]
The fitting portions 16 into which the first holding metal fittings 9 and the second holding metal fittings 10 are fitted are formed on both left and right sides. The fitted portion 16 is formed in a concave shape into which the fitting portions 9c and 10c enter. In other words, edges are formed at both front and rear ends so that positioning in the front and rear direction can be performed.
[0033]
A sliding groove 17 penetrating in the front-rear direction is formed in the middle part in the left-right direction and in the vicinity thereof. The sliding groove 17 includes an opening 17a that opens on the upper surface, and retaining portions 17b, 17b that extend to the left and right sides inside. The retaining portion 17b is inclined so as to rise toward the outside to enhance the retaining force.
[0034]
The heat insulating member 7 may be formed by dividing it into right and left. However, if it is formed by one member as shown in the figure, the strength is high and the number of parts is reduced, which is convenient in terms of cost and assemblability.
[0035]
The slide fitting 6 is formed of a metal plate, and includes a pair of left and right superposed members (a first superposed member 18 and a second superposed member 19). In addition, the plate thickness is set to be thicker than in the case of the suspension 8. Each of the overlapping members 18 and 19 has a vertical portion slidable between the openings 17a of the sliding groove 17 and vertical pieces 18a and 19a obtained at the time of polymerization. The retaining pieces 18b, 19b which are inclined toward are continuously provided. The lower portions of the vertical pieces 18a, 19a and the retaining pieces 18b, 19b constitute a sliding portion 6a that slides in the sliding groove 17.
[0036]
The length of the sliding portion 6a in the front-rear direction is set to be longer than the length of the heat insulating member 7 so that a desired amount of sliding can be performed on the heat insulating member 7.
[0037]
As described above, in this example, a hook for a square goby is shown as the hook 8, but the hook of the square goby must be attached to and detached from the slide fitting 6 when supporting the roof plate 4a. Therefore, the first stacking bracket 18 does not form anything on the vertical piece 18a, but the upper end of the second stacking bracket 19 has a receiving piece that is folded toward the first stacking bracket 18 and receives the roof plate 4a to be supported. 19c are continuously provided. In order to integrate the first and second metal fittings 18 and 19, and to attach the hanging member 8, an insertion hole 18c is provided above the vertical piece 18a of the first metal fitting 18 and a second metal fitting. A screw hole 19d is formed in the upper part of the vertical piece 19a of 19, and the bolt 20 is screwed and held from the side of the first overlapping metal fitting 18.
[0038]
In order to obtain a high degree of integration, concave portions 21 or convex portions 22 that fit each other are formed on the front and rear ends of each of the metal fittings 18 and 19 as shown in FIG.
[0039]
At both front and rear ends of the retaining pieces 18b and 19b, stoppers 23 for preventing the retaining pieces 23 from falling off from the heat insulating member 7 are formed by bending pieces bent downward.
[0040]
Further, the lengths of the retaining pieces 18b, 19b in the left-right direction are set as follows in relation to the fitting portions 9c, 10c of the fixing bracket 5. That is, the length is set so that the upper end portions of the fitting portions 9c and 10c and the retaining pieces 18b and 19b overlap in the vertical direction.
[0041]
In order to assemble the slide fitting 6 with respect to the heat insulating member 7, it is necessary to insert the slide fitting 6 into the sliding groove 17 of the heat insulating member 7 from the front-back direction. In the two-layer metal fitting 19, it is preferable to form it on the rear end and on the opposite side.
[0042]
After each of the overlapping metal fittings 18 and 19 is inserted from the front or the rear and held in the sliding groove 17, they are overlapped, and the overlapping state is held by the concave portion 21, the convex portion 22 and the bolt 20.
[0043]
It is to be noted that even if the respective metal fittings 18 and 19 are polymerized in advance, they can be mounted in the sliding grooves 17. That is, as shown in FIG. 7, it is preferable to form a stopper 23 in a non-bending state on the insertion side, and after insertion, fold it into a predetermined stopper shape.
[0044]
Hereinafter, the operation and effect of the support 1 configured as described above will be described.
The fixing to the underlaying roof 2 is performed by loosening the bolts 13 nuts 14 of the fixing metal fittings 5, then installing the fixing portion 2 a of the underlaying roof 2 so as to sandwich it between left and right, and tightening the bolts 13 nuts 14. Then, the middle part of the sliding metal fitting 6 in the longitudinal direction is aligned with the heat insulating member 7 so that the sliding metal fitting 6 can slide equally in any of the front and rear directions. Is locked to the fastening portion at the upper end of the roof plate 4a, and is simultaneously fixed to the support 1 by using the bolt 20 of the slide fitting 6, the contact plate 24, and the nut 25.
[0045]
When the roof 4 is completed, even if the roof plate 4a expands and contracts, the sliding fitting 6 slides on the heat insulating member 7 following the expansion and contraction. For this reason, the distortion accumulated in the roof plate 4a can be absorbed, and the noise can be prevented.
[0046]
When sliding, the sliding groove 17 of the heat insulating member 7 has the opening 17a and the retaining portion 17b as described above, and the sliding portion 6a of the sliding metal fitting 6 has a vertical portion (vertical portion). Pieces 18a, 19a) and the retaining pieces 18b, 19b, so that the sliding of the slide fitting 6 is restricted mainly at the vertical portion and the retaining pieces 18b, 19b. In addition, stable and smooth sliding can be performed without being shaken in the left-right direction or the up-down direction. In particular, the presence of the retaining pieces 18b and 19b ensures that the retaining piece 18b and 19b are retained, and the support 1 has high strength against negative pressure and positive pressure.
[0047]
Further, since the configuration for this is composed of three types of the fixing bracket 5, the heat insulating member 7 and the sliding member 6, it is simple, and the assembling work and the management of parts are also easy.
[0048]
Moreover, since the metal fittings for fixing to the underlay roof are made of metal, unlike the case of synthetic resin, cracks and the like hardly occur even when tightened tightly. Therefore, high strength can be obtained.
[0049]
Similarly, the slide fitting 6 is made of metal, and is formed of a metal plate having a necessary and sufficient thickness instead of a thin metal plate such as the hook 8 or the like. Since the sliding portion 6a is formed at the upper side, high durability against upward pulling can be obtained.
[0050]
In addition, the heat insulating member 7 may be formed to have a predetermined thickness necessary for heat insulation at least outside the sliding groove 17, and the amount of the material, that is, the amount of synthetic resin used can be minimized. Therefore, it is possible to reduce the cost and to reduce the amount of harmful gas generated even in the event of burning by fire.
[0051]
Further, since the upper end portions of the fitting portions 9c and 10c of the fixing member 5 and the retaining pieces 18b of the sliding member 6 are vertically overlapped, even if the heat insulating member 7 is burned by a fire, the above-described operation is performed. The upper end portion and the sliding portion 6a are caught in the vertical direction, and the fixing metal 5 and the sliding metal 6 are not separated in the vertical direction. For this reason, the inconvenience of the roof flying can be avoided.
[0052]
Hereinafter, another example will be described. Note that the same or similar portions as the above-described configuration are denoted by the same reference numerals as in the above-described example, and detailed description thereof will be omitted.
[0053]
Not all of the above-mentioned members are necessary. For example, as shown in FIG. 8, even if the second auxiliary fitting 12 is omitted, a sufficient fixing strength can be obtained.
[0054]
In order to increase the strength, the suspension 8 may be appropriately devised. As shown in FIG. 9, a double folded portion 8b is formed at the end of the extension 8a extending horizontally from the lower end. Alternatively, the rigidity of the entire suspension 8 may be increased, or the double fold 8b may be formed up to the insertion hole 8c as shown in FIG. 10 to further enhance the reinforcement.
[0055]
Further, as shown in FIG. 11, a bolt 20 for attaching the suspension 8 may be attached upward. That is, in this case, a receiving piece 18d for receiving the roof plate 4a is formed at the upper end of the first metal fitting 18 constituting the sliding metal fitting 6, and a similar receiving piece 19c is also provided at the upper end of the second metal fitting 19. Form. The receiving piece 19c of the second stacking fitting 19 is formed at a position lower than the receiving piece 18d of the first stacking fitting 18, a screw hole is formed in this receiving piece 19c, and the bolt 20 is screwed from below. Fix it. The head of the bolt 20 may be stopped by caulking.
[0056]
The first overlap metal fitting 18 and the second overlap metal fitting 19 are fixed in advance by appropriate means such as rivets 26 or the like. As shown by the broken line, the convex portion 21 and the concave portion 22 as described in FIG. 6 may be formed together.
[0057]
In the case of the support 1, a locking piece 8 c that bends downward as shown in the drawing is formed at the tip of the extension 8 a formed at the lower end of the suspender, and the receiving piece 19 c of the second metal fitting 19 is formed. It is good to lock to the end. Since the locking piece 8c is locked to the end of the receiving piece 19c, even if the suspension 8 is pulled upward by receiving a negative pressure, a force opposing the force can be generated, and the strength can be increased.
[0058]
FIG. 12 shows a use state of the support 1 using a round goby type as the suspension 8. FIG. 13 is an exploded perspective view of the support 1, and FIG. 14 is a sectional view.
[0059]
Unlike the square goby slings 8, the round goby slings 8 do not need to be attached and detached at the time of supporting the roof plate 4 a, so that the sliding bracket 6 is substantially identical to the pair of left and right first overlapping brackets 18. What is necessary is just to comprise the 2nd superposition metal fitting 19, and to pinch the suspension 8 between these. The insertion holes 18c and 19e into which the bolts 20 for fixing the hangers are inserted may be simply square holes, and it is not necessary to cut a screw as in the above example.
[0060]
In addition, the fixing bracket 5 may have an appropriate configuration based on a pair of left and right first holding metal fittings 9 and second holding metal fittings 10. Reference numeral 27 in the drawing denotes an auxiliary metal fitting for fastening.
[0061]
FIG. 15 shows another example of the round goby type fixing bracket 5. In this case, only the pair of left and right first holding members 9 and second holding members 10 are provided.
[0062]
FIG. 16 shows that a pair of left and right first holding members 9 and second holding members 10 can be connected to the heat insulating member 7 from the left and right directions and can be further connected in the vertical direction to increase the fixing strength. This is an example that can be used. That is, as shown in FIG. 17, a regulating portion 28 that covers the upper end of the heat insulating member 7 like a lid is formed, and under the regulating portion 28, the fitting portions 9c and 10c of the sandwiching members 9 and 10 are formed. A gap (insertion groove) for inserting the upper end is formed. The regulating portion 28 is not formed on the entire upper surface of the heat insulating member 7, but is formed only at a position corresponding to the outer portion of the fitting portion 9c, 10c of each of the holding members 9, 10, as shown in FIG. You may do it.
[0063]
In addition to the above, the retaining pieces 18b and 19b in the sliding portion 6a of the sliding fitting 6 may be formed in an appropriate shape such as, for example, horizontally, and as shown in FIG. The bent edges 18f and 19f facing upward may be formed at the tip to increase the rigidity of the sliding portion 6a and improve the stability.
[0064]
Further, even if the hook 8 having a square goby is used, the hook 8 can be positioned at the center in the left-right direction by configuring the sliding bracket 6 as shown in FIG. That is, the sliding metal fitting 6 is composed of a first overlapping metal fitting 18 having a receiving piece 18d and a second overlapping metal fitting 19 formed at a low height corresponding to the sliding portion 6a and having no receiving piece. These are superimposed on each other in advance via a spacer 29 having the same thickness as the plate material constituting the hanging member 8, and are integrated by an appropriate means such as a rivet 26 or the like. Then, a bolt 20 is attached to the vertical piece 18a of the first stacking metal fitting 18, or the bolt 20 is attached as shown in the drawing. At the lower end of the suspension 8, an extended portion 8 a extending in the horizontal direction is formed, and at the upper end of the backing plate 24 that contacts the outer surface of the suspension, a receiving piece 24 a for receiving the roof plate 4 a is formed. are doing. When the suspension 8 and the backing plate 24 are attached using the bolts 20 and the nuts 25, the extended portions 8 a of the suspensions 8 come into contact with the upper end of the second overlapping metal fitting 19, and the lower end of the backing plate 24 is connected to the suspension. The dimensions are set in advance so as to abut on the extended portion 8a.
[0065]
With this configuration, both the hooks of the square goby 8 and the hooks 8 of the round goby can be used.
[0066]
As shown in FIG. 21, the sliding fitting 6 may be formed by bending a single metal plate into an “D” shape, and forming an insertion groove for inserting a hook at the middle in the left-right direction. Similarly, both square and round goby can be used.
[0067]
Further, the fitting portions 9c, 10c of the first holding member 9 and the second holding member 10 may be formed in a shape as shown in FIG. That is, although it is basically U-shaped, the rigidity is increased by forming integrally folded portions 9f and 10f that rise vertically on the bases that form the upper ends of the fitting portions 9c and 10c.
[0068]
In particular, when the heat insulating member 7 has a structure having the restricting portion 28, it is preferable to set the folded portions 9 f and 10 f so as to abut the end face of the restricting portion 28 as shown in FIG. 23. As described above, the force of the action and reaction acts on the opposing portions of the fitting portions 9c, 10c having high rigidity and the heat insulating member 7, but this load can be satisfactorily received by the many opposing surfaces, and the strength of the support 1 Can be further increased.
[0069]
The above configuration is an embodiment of the present invention,
The underlay roof 2 corresponds to the base material of the present invention,
The first clamp 9 and the second clamp 10 correspond to a pair of left and right clamps,
The vertical pieces 18a and 19a correspond to the vertical portions of the present invention,
The present invention is not limited only to the above configuration.
[0070]
For example, the formation of the retaining portion of the sliding groove may be a shape that spreads only to one of the right and left from the hanging position of the opening, and if the retaining portion has a shape that expands to the left and right sides, The sliding portion of the sliding fitting may be formed in a shape that slides only one of the left and right retaining portions.
[0071]
Further, a portion for locking the roof plate 4a may be provided on the sliding metal fitting, and the roof plate 4a may be directly supported by the sliding metal fitting.
