表基材2は、金属板を素材とする金属製の部材であり、金属屋根材1が屋根下地の上に配置された際に屋根の外面に表れる部材である。図3に特に表れているように、表基材2には、天板20a及び周壁20bを有する箱状の本体部20が設けられている。 <About front substrate>
The
裏基材3は、本体部20の開口を塞ぐように表基材2の裏側に配置された部材である。本体部20の開口は、本体部20の周壁20bの反天板側端部の内縁によって縁取られている。裏基材3としては、アルミ箔、アルミ蒸着紙、水酸化アルミ紙、炭酸カルシウム紙、樹脂フィルム又はガラス繊維紙等の軽量な素材を用いることができる。これらの軽量な素材を裏基材3に用いることで、金属屋根材1の重量が増大することを回避することができる。 <About back substrate>
The
芯材4は、例えば発泡樹脂等により構成されるものであり、本体部20と裏基材3との間に充填されている。芯材4の素材としては、特に制限が無く、ウレタン、フェノール、ヌレート樹脂等を用いることができる。ただし、屋根材においては不燃認定材料を使用することが必須となる。不燃材料認定試験は、ISO5660-1コーンカロリーメーター試験法に準拠した発熱性試験が実施される。芯材4となる発泡樹脂が発熱量の多いウレタンなどの場合は、芯材4の厚みを薄くしたり、発泡樹脂に無機発泡粒子を含有させたりすることができる。本体部20と裏基材3との間に発泡樹脂が充填されることで、樹脂シート等の裏打ち材を表基材2の裏側に張り付ける態様よりも、表基材2の裏面に芯材4を強固に密着させることができ、雨音性、断熱性及び耐踏み潰れ性等の屋根材に求められる性能を向上させることができる。 <About core material>
The
板状補強部材5は、本体部20の天板20aよりも裏基材3に近い位置で芯材4に埋め込まれた板体である。金属屋根材1の裏側、すなわち本体部20の開口部分及び裏基材3部分は、本体部20の天板20a部分と比較して強度が低い。裏基材3に近い位置で芯材4に板状補強部材5が埋め込まれていることで、金属屋根材1の裏側が板状補強部材5によって補強され、金属屋根材1の耐風圧性能を向上できる。耐風圧性能とは、金属屋根材1の軒側端部1Eを浮き上げようとする荷重に対する抵抗性能である。このような荷重は、屋根下地に緊結されている金属屋根材1に吹き付けた風に起因して生じ得る。 <About plate-like reinforcing members>

Next, FIG. 7 is explanatory drawing which shows the 1st modification of the
次に、図8は、図1の金属屋根材1の第2変形例を示す説明図である。図8に示す第2変形例は、軒棟方向6に関して本体部20の開口の全域にわたって板状補強部材5が延在されていない点で図1の態様と異なっている。図8に示すように、軒方向7に連続的に延在された板状補強部材5が、金属屋根材1に緊結部材が打ち込まれる位置から金属屋根材1の軒側端部1Eまで延在されていてもよい。金属屋根材1が屋根下地に緊結されているとき、金属屋根材1の軒側端部1Eを浮き上げようとする荷重は、金属屋根材1の緊結部分から軒側端部1Eまでの領域において金属屋根材1を反らせようとする。金属屋根材1に緊結部材が打ち込まれる位置から金属屋根材1の軒側端部1Eまで板状補強部材5が延在されていることで、金属屋根材1の重量増大を回避しつつ、より確実に金属屋根材1の耐風圧性能を向上できる。 <About the second modification>

次に、図9は図1の金属屋根材1の第3変形例を示す説明図であり、図10は図9のバーリング孔50周辺における金属屋根材1の断面図である。図9及び図10に示す第3変形例は、軒棟方向6及び軒方向7の両方に関して本体部20の開口の全域にわたって板状補強部材5が延在されていない点で、図1の態様と異なっている。換言すれば、第2変形例よりも軒棟方向6及び軒方向7に板状補強部材5がさらに小さくてもよい。図9に示すように、金属屋根材1に緊結部材が打ち込まれる位置の周辺のみに板状補強部材5が延在されていてもよい。板状補強部材5が金属屋根材1の幅方向に連続的に延在されていることから、金属屋根材1の裏面の広い領域が1枚の板状補強部材5で補強されている。このため、幅方向に離間して複数の板状補強部材を配置する態様(後述の第4変形例)と比較して製造工程が簡略化される。このような態様でも、他の金属屋根材1の角部が当たることによって金属屋根材1の裏面に潰れが生じることを回避できる。 <About the third modification>
Next, FIG. 9 is explanatory drawing which shows the 3rd modification of the
次に、図11は、図1の金属屋根材1の第4変形例を示す説明図である。図11に示す第4変形例は、複数の板状補強部材5が金属屋根材1の長手方向1L(幅方向)に互いに離間して配置されている点で、図1の態様と異なっている。板状補強部材5は、その長手方向が軒棟方向6(金属屋根材1の短手方向1S)に沿うように延在されている。このように、板状補強部材5が幅方向に互いに離間して配置されていることで、必要な耐力を確保しつつ、金属屋根材1の重量増を抑えることができる。 <About the fourth modification>
Next, FIG. 11 is explanatory drawing which shows the 4th modification of the
図示はしないが、第5変形例として、板状補強部材5を用いずに、裏基材3の素材を表基材2と同様の金属板とすることもできる。 <About the fifth modification>
