Description

【０００１】
【発明の属する技術分野】
本発明は既設屋根上に新設屋根を重ね葺きするのに用いられる重ね葺き用固定具およびこの固定具を用いた改修構造に関する。
【０００２】
【従来の技術】
先行文献1には、屋根補修工法が記載され、同工法に用いられるクランプ金具として、断面山形の底面部に、その頂部を貫通してフックボルトのナット直下の軸部回りに嵌合せしめる穴と、該穴と底面部の上記端縁とを連通せしめてフックボルトの軸部を上記穴に嵌入させるガイド溝からなる切欠きを形成し、且つ、上記ガイド溝は上記穴との連接部の溝幅が上記孔の径よりも小さく、溝幅が底面部端縁の開口に向けて拡大するテーパー状に形成したものが記載および図示されている。
ところで、かかるクランプ金具では、底面部が既設の波形スレートの山部に取り付けられた状態で、この山部に載乗している形になるため、金具そのものがフックボルトの軸部回りに回転してしまう危惧があり、このような場合、金具における上面部と新設の屋根材との間の取り付け位置関係に狂いが発生する不都合がある。
さらに、金具が回転した場合には、波形スレートの山部に対してほぼ二点接触状に載乗することになるので、甚だ不安定な取り付け状態を呈し、このような言わばガタガタした状態の金具に取り付けられる新設屋根材もまたがたついてしまうことになる。
そして、金具は、既設の波形スレートの山部にピンポイント的に取り付けられているため、金属製の新設屋根材の重量や風雨の負荷が金具を経て波形スレートの山部における金具取り付け部分に集中することになり、強度的にも不安が残る屋根構造になっている。
【０００３】
また、ボルトの軸部と穴との嵌合関係を、穴およびこの穴に続くガイド溝の拡開により確保している構成のものであるため、この拡開によって嵌合関係という位置規制が失われる恐れがあるものであり、穴からボルトが外れてしまうことも起こり得る構造上の不備がある。この点は、底面部が断面山形で既設の波形スレートの山部に沿う形状であること、そして、新設の金属板屋根材の重量が負荷されることが相乗することにより、穴およびガイド溝は拡開動作し易くなっているといえる。
また、座金下のパッキン材により得ている接触摩擦抵抗は、パッキン材の劣化或いは振動等によって損なわれる虞れがあり、既設屋根との接続関係に対する貢献度は低いものになる。
このような拡開状態になれば、既設屋根材に対する固定具の接続・固定関係が失われるわけであるから、固定具ともども新設屋根材はフリーになってしまうという重大な問題に発展することにもなりかねない。

【発明が解決しようとする課題】
解決しようとする課題は、第１には、新設の屋根材との間の取り付け位置関係に狂いがなく、既設屋根に新設屋根をガタつかぬように取り付けられ、しかも、新設屋根の重量や風雨による負荷にも不都合をきたさず、新設屋根を既設屋根すなわち母屋側との安定した接続・固定関係に重ね葺きして施工することが可能であり、製作容易で経済的であり、既設屋根への据わりが安定しており、新設屋根の重量や風雨による負荷に対して強度的にも堅牢に重ね葺きして施工することが可能な重ね葺き用固定具を提供することにある。
第２には、さらに、接続・固定関係に強制的に規制することで、より堅固な接続・固定関係に重ね葺きして施工することが可能な重ね葺き用固定具を提供することにある。
第３には、新設の屋根材との間の取り付け位置関係に狂いがないと共に既設屋根に対して新設屋根がガタつかず、しかも、新設屋根の重量や風雨による負荷に充分に耐え、固定具を経た新設屋根と既設屋根すなわち母屋側との安定した接続・固定関係により、既設屋根上に新設屋根が確実に重ね葺きされている改修構造を提供することにある。
【０００６】
【課題を解決するための手段】
本発明は前記した課題を達成するため、重ね葺き用固定具では、既設屋根の突条部上方に突出するボルトのネジ部分に螺合されるナットにより母屋材に固定された既設屋根に対し重ね葺きされる新設屋根を、前記既設屋根上に連結固定する重ね葺き用固定具において、前記既設屋根の突条部上に取り付けられる下取付部と、既設屋根の凹条部上に着地可能な脚部と、前記新設屋根を取り付ける上取付部とを備えており、前記下取付部には、前記ナットおよび座金の径よりも大径のガイド穴と、該ガイド穴に連通して、前記ボルトのネジ部分の径よりもやや大幅の挿入溝を形成しており、脚部が、下取付部の一側縁または両側縁に延設され、既設屋根の凹条部に沿う形状で且つ凹条部に面状に着地可能な脚形状であることを特徴とする。
また、前記した重ね葺き用固定具では、ボルトを挿入溝内に抜止規制可能な規制手段を有していることを特徴とする。
そして、かかる固定具を用いた改修構造では、前記の重ね葺き用固定具を用い、既設屋根上に新設屋根を重ね葺きしてなる改修構造であって、前記固定具の脚部を母屋材に固定された既設屋根の凹条部上に着地し、下取付部を既設屋根の突条部上に載置すると共にボルトがガイド穴から挿入溝に挿入するようにスライドし、凹条部と脚部との接触関係により下取付部が既設屋根上に固定された状態の固定具における上取付部上に新設屋根を構築したことを特徴とする。

【００１５】
図５および図６には本発明の重ね葺き用固定具を用いた改修構造における実施の1形態として、図１の固定具を用いて既設屋根材上に新設屋根材を重ね葺きした屋根構造を例示しており、母屋材１９に小波スレート製の既設屋根材１０を敷設した状態に、既設屋根材１０の突条部１０ａ上方に突出するフックボルト１１のネジ部分１１ａに螺合したナット１２により座金１３およびパッキング等の弾性材１４を介在させて固定している。
既設屋根材１０における上方へ突出しているネジ部分１１ａ位置の突条部１０ａには固定具１の下取付部２をこれのガイド穴４にナット１２、座金１３、弾性材１４が通るように被せて載置すると共に凹条部１０ｂに脚部３を着地し、固定具１を突条部１０ａ並びに凹条部１０ｂに沿いスライドさせて、突条部１０ａ上面と弾性材１４下面との間に下取付部２を押し込むことにより、フックボルト１１をガイド穴４側から挿入溝５に挿入してある。
この挿入状態では、脚部３が凹条部１０ｂ上面に着地して接触・係合して、突条部１０ａ上における下取付部２を、フックボルト１１を軸線とする回転を阻止して回り止めすることで、既設屋根面上に固定具１を回転不可能な固定状態に規制し、上取付部５に対する新設屋根材１５の取付位置を整えてある。
【００１６】
既設屋根材１０上には折板製の新設屋根材１５を敷設し、既設屋根材１０上に取付固定された固定具１における上取付部５上面には、隣り合う左右の新設屋根材１５における左右の側縁部１５ａを上下重合状に載置すると共に、この左右側縁部１５ａをタッピングネジ等の留め具１６で上取付部５上に接続固定してある。留め具１６の拡大頭部１６ａと側縁部１５ａとの間には座金１７およびパッキング等の弾性材１８を介在させて雨仕舞している。この弾性材１８の劣化或いは振動等によっても、固定具１と既設屋根材１０すなわち母屋側との固定関係は堅持され、かかる固定具１を経て既設屋根材１０上に新設屋根材１５が確実に重ね葺きされている。

固定具１を既設屋根面に沿いスライドさせて、突条部１０ａ上面と弾性材１４下面との間に下取付部２を押し込み、フックボルト１１がガイド穴６側から挿入溝７に挿入して、脚部３が凹条部１０ｂに着地している接触・係合状態では、抜止ストッパー８はストッパー先端部８ａが溝奥のフックボルト１１のネジ部１１ａに溝入口側から当接し、下取付部２の逆スライドすなわちフックボルト１１が挿入溝７から抜け外れる方向への動きを阻止することで、フックボルト１１を挿入溝７内に抜止規制してある。
【００２４】

【発明の効果】
Ａ．請求項１により、既設屋根材の凹条部に固定具の脚部が着地して接触・係合関係になることによって、固定具が回り止めされて取付位置に固定状に規制されることになるので、新設の屋根材との間の取り付け位置関係に狂いが発生せず、既設屋根に新設屋根をガタつかぬように取り付けることができる。しかも、新設屋根の重量や風雨による負荷に対しても、突条部上の下取付部と凹条部上の脚部とによる分散・支持構造になっていることで強固であることにより不都合をきたさず、新設屋根を既設屋根すなわち母屋側との安定した接続・固定関係に重ね葺きして施工することができる。
したがって、既設屋根上に新設屋根を重ね葺きするのに有用であり、また、間に断熱材或いは断熱空間層を形成するような上下の二重葺き屋根の施工にも有用である。
また、製作容易で経済的であり、ぐらつきや転倒がなく、既設屋根への据わりが安定した取付状態を得ることができる。さらに、新設屋根の重量や風雨による負荷に対して強度的にも堅牢な構造のものに重ね葺きして施工することができる。
Ｂ．請求項２〜５により、さらに、接続・固定関係に強制的に規制することで、より堅固な接続・固定関係に重ね葺きして施工することができる。
Ｃ．請求項６により、新設の屋根材との間の取り付け位置関係に狂いがないと共に既設屋根に対して新設屋根がガタつかず、しかも、新設屋根の重量や風雨による負荷に充分に耐え、固定具を経た新設屋根と既設屋根すなわち母屋側との安定した接続・固定関係により、既設屋根上に新設屋根が確実に重ね葺きされていて堅牢な改修構造である。

Prior Document 1 describes a roof repair method, and as a clamp fitting used in the method, a hole that penetrates the top of the bottom part of the cross-sectional mountain shape and fits around the shaft part directly below the nut of the hook bolt The hole and the end edge of the bottom surface portion are communicated to form a notch formed by a guide groove for fitting the shaft portion of the hook bolt into the hole, and the guide groove is a groove of the connecting portion with the hole. It is described and illustrated that the width is smaller than the diameter of the hole and the groove width is tapered so as to expand toward the opening of the bottom edge.
By the way, in such a clamp metal fitting, since the bottom part is mounted on the peak part of the existing corrugated slate, it is mounted on this peak part, so the metal part itself rotates around the shaft part of the hook bolt. In such a case, there is an inconvenience that the mounting position relationship between the upper surface portion of the metal fitting and the newly installed roofing material is distorted.
Furthermore, when the bracket rotates, it will be mounted in a two-point contact with the peak portion of the corrugated slate, so it exhibits a very unstable mounting state, and in this way the bracket is in a rattling state. The new roofing material attached to the door will also strangle.
And since the metal fittings are pinpointly attached to the peak portions of the existing corrugated slate, the weight of the new metal roofing material and the load of wind and rain are concentrated on the metal fitting mounting portion of the corrugated slate mountain through the metal fittings. As a result, the roof structure remains uneasy in terms of strength.
[0003]
In addition, since the fitting relationship between the shaft portion of the bolt and the hole is ensured by expanding the hole and the guide groove following the hole, the position restriction of the fitting relationship is lost by this expansion. There is a structural defect that can cause the bolt to come off from the hole. This is because the bottom part is a cross-sectional chevron shape that follows the peak part of the existing corrugated slate, and the weight of the new metal sheet roofing material is combined, so the hole and the guide groove are It can be said that the expansion operation is easy.
Further, the contact friction resistance obtained by the packing material under the washer may be damaged by deterioration or vibration of the packing material, and the contribution to the connection relationship with the existing roof becomes low.
In such an expanded state, the connection / fixing relationship of the fixtures to the existing roofing material is lost, so that the new roofing material will become free with the fixtures. It can be.
