Description

【0001】
【発明の属する技術分野】
本発明は、屋根材として今までにない重厚感、施工性を有し、かつ防水機能、断熱機能、結露防止機能、雪止め機能、等を形成した屋根材に係るものである。
【0002】
【従来の技術】
一般に、金属製板材をロール成形、プレス成形等して加工した屋根材は数多く上市され、その形状は、所謂引っ掛け構造であった。(例えば、特許文献1、2参照)。また、従来、屋根は耐振性、強度、施工性、重量の関係で、金属製屋根材が注目を浴びてきた。しかしながら、金属製屋根材は意匠性に乏しく、また、凹凸が大きい瓦屋根のような屋根材に比べて、屋根に積もった雪が簡単に軒下に落下する危険性があり、屋根材本体に雪止め機能を付加した屋根材を使用した屋根構造が開発されている。(例えば、特許文献3、4参照)。

【発明が解決しようとする課題】
しかしながら、特許文献1、2は引っ掛け構造であるために、勾配が急な屋根に使用した際に、連結した上段の屋根材が自重で落ちてくるので、上段の屋根材の固定部を固定具(釘)で固定するまで、屋根材が落ちないように手で押さえている必要があり、施工が大変であった。しかしながら、特許文献3、4の構造では、下段の屋根材に上段の屋根材を施工する際に、上段の屋根材に折り曲げ加工を施して屋根材を施工するものであった。このために、▲1▼施工性が悪い、▲2▼施工が難しい、▲3▼施工を確実にしないと雨漏れの原因になる、▲4▼屋根材表面に傷が付く、等の欠点があった。
【0005】
【課題を解決するための手段】
本発明はこのような欠点を解決するために、化粧面の水上側の先端を上方に突出した第1防水片と、第1防水片の先端を水上側に突出した嵌合片と、第1防水片の先端を水下側へ突出した第2防水片と、化粧面の先端を水上側で上方へ突出した固定片を形成し、化粧面の水下側の先端には上方に突出した垂直片と、下方に突出した段差化粧面と、化粧面の水下側の先端近傍を下方に突出した最奥片と、最奥片の先端を水下側に突出した差込片と、化粧面と最奥片と差込片とから係合溝を形成すると共に、嵌合片の水上端と第2防水片の水下端間の幅と、最奥片と段差化粧面間の幅をほぼ同じ長さに形成した屋根材を提供するものである。
【0006】
【発明の実施の形態】
以下に図面を用いて本発明に係る屋根材について詳細に説明する。図1は金属製屋根材Bと裏打材Cよりなる屋根材Aの代表的一例を示す説明図、図2(a)、(b)は屋根材Aの施工状態を示す説明図である。図中、αは下地、βは釘等の固定具を示している。
【0007】
下地αは、新築の際は図2(a)、(b)に示すように垂木1、野地板2、防水シート3(一点鎖線で示す)から構成した木造下地を示したものである。すなわち、垂木1上に野地板2を敷設し、野地板2上に防水シート3を配設した一般的な構造の下地αである。また、下地αとしてH形鋼、I形鋼、ミゾ形鋼、軽量ミゾ形鋼、リップ溝形鋼、等辺山形鋼、不等辺山形鋼、角形鋼(角パイプ)、円形鋼(円形パイプ)、等を使用した鉄骨下地でも良いものである。勿論、既存の屋根をそのまま改修する屋根の際には、これら下地α上に新生瓦や瓦棒等の既存屋根(図示せず)が形成された既存屋根構造が下地αとなるものである。勿論、防水シート3を形成しない下地αでも良いものである。
【0008】
金属製屋根材Bは、例えば金属板(カラー鋼板、銅板、アルミニウム板、チタン板、ステンレス板、サンドイッチ鋼板、クラッド鋼板等)等をロール成形、プレス成形、押出成形、等によって形成したものである。勿論、屋根材Aの表面材として、金属製屋根材Bの代わりに窯業系素材、もしくは合成樹脂材(プラスチック)、等で形成してもよいものである。
【0009】
さらに説明すると、金属製屋根材Bは長尺板状であり、図1に示すように、略水平面状の化粧面4と、裏面5と、化粧面の水下側の先端には上方に突出した垂直片6と、下方に突出した段差化粧面6aと、段差化粧面6aと化粧面4に沿って内側方に突出した上面7と、上面7の先端を下方に突出した最奥片8と、最奥片8の先端を水下側に突出した差込片9と、上面7と最奥片8と差込片9とから略コ字状の係合溝10を形成し、上面7と係合溝10により挿入間隙11を形成して雄型連結部12としたものである。
【0010】
また、図1に示すように、化粧面4の水上側端部分には、化粧面4の上端部分をさらに水上側に突出し、先端を水下側に垂下した固定片15と、固定片15の下端を上方に屈曲した第1防水片13と、第1防水片13の先端を水上側に突出した上面14と、上面14と固定面15とから断面略コ字状に形成した前記差込片9と嵌合する嵌合溝16と、上面14の先端を水下側に屈曲した嵌合片13aと、嵌合片13aの先端を、水下側でかつ上方へ突出した第2防水片13bとから雌型連結部17を形成したものである。
【0011】
垂直片6は、雪止機能と、連結部分に雪による空洞を形成し、スガ漏れによる連結部からの雨漏れを防止するものである。
【0012】
段差化粧面6aは、第2防水片13bと図2(b)に示すように連結されるものである。つまり、嵌合時に段差化粧面6aが第2防水片13bの先端部分に衝突し、第2防水片13bがその衝突力により自己の持つスプリングバックにより変形し、強固に連結されるものである。
【0013】
嵌合片13aの水上端と第2防水片13bの水下端間の幅Tと、最奥片8と段差化粧面6a間の幅をtとすると、T<tかつT≒t(ほぼ等しい)の関係で、ほぼ同じ長さに形成したものである。実際には、t=T+(0〜5mm)位である。これは、上記第2防水片13bがその衝突力により自己の持つスプリングバックにより変形し、段差化粧面6a内部に強固に連結されるために必要な関係である。
【0014】
第1防水片13は、上側に屈曲することにより防水機能を付加すると共に、嵌合片13aの一部としても機能する部分である。
【0015】
第2防水片13bは屋根材Aに吹き付ける雨、風が、直接屋根材Aの上面7に吹き付けるのを防止し、屋根材Aが風により剥がされるのを防止するものである。つまり、図3に示すように、風が矢印に示すように吹き付けると、下段の屋根材Aの第2防水片13bは風により一点鎖線矢印アに示すように防水片13の先端を中心に回転するように浮き上がる力が働くが、逆に上面14が一点鎖線矢印イに示すように上段の屋根材Aの差込片9を押さえ込むような力が働き係合力が強化され、屋根材Aが風により剥がされるのを防止するものである。
【0016】
このように、屋根材A同士の連結部内で相対する力が相殺されるために、屋根材Aが破壊されたり、固定片15に形成した固定具βが下地αより抜け落ちない限り、屋根材Aが風により剥がされることはないものである。
【0017】
第2防水片13bは、防水片13の先端を水下側へ突出することにより、断面コ字状の溝を形成し、この溝により入ってこようとする風雨を、逆方向に回転させて排出し、防水性を向上するための形成したものである。
【0018】
裏打材Cは防水材、断熱材、吸音材、緩衝材、防火材、結露防止材、等として機能するものであり、不織布、合成樹脂製発泡シート(架橋化発泡ポリエチレンシート、等)、ロックウール、テックス(軟質繊維板)、ゴムシート、樹脂シート、等、あるいはこれらに遮音材、耐火材等を含浸、含有、混合、積層(一層、あるいは複数層)、サンドイッチ、等したものを使用することもできる。特に不織布は、縦糸と横糸を交差させて繊維から織物にする従来の方法と異なり、各種の繊維を接着剤等で結合した不織布等である。この不織布はまず繊維が平行に交差するか、また無秩序に配列された薄いフェルト状のものを接着剤で結合させるか、または主体となる繊維状態の中に別の熱可塑性繊維を混在させて、加熱および加圧して溶融し相互に結合させたりして作られたものである。勿論、素材自体に防水性の無いものには、樹脂材をコーティング、あるいは撥水剤、防水コーティング剤、等で防水機能を片面あるいは両面に付加したものである。
【0019】
以上説明したのは本発明に係る屋根材の一実施例にすぎず、図4(a)、(b)〜図6(a)、(b)に示すように屋根材Aを形成することもできる。
【0020】
【発明の効果】
以上説明したように、本発明に係る屋根材によれば、▲1▼第1防水片と第2防水片の形成により、屋根材を落とし込み構造としても、防水性を維持できる。▲2▼落とし込み構造であるために、勾配が急な屋根に使用しても連結した上段の屋根材が自重で落ちてくることがなく、固定するまで屋根材が落ちないように手で押さえている必要が無いために施工が楽である。▲3▼化粧面の水上端部と固定片が同一レベルで形成されているために、段差が小さくて良く、連結部分の荷重による変形がない。▲4▼上段の屋根材を下段の屋根材へ施工した際に、下段の屋根材の第2防水片が上段の屋根材の上面に接触し、常時第2防水片が係合溝内でスプリングバック効果を発揮し、防水性、気密性を向上する。▲5▼第2防水片の形成により、屋根材同士の連結部内で相対する力が相殺(風により下段の屋根材を剥がそうとする力が、上段の屋根材を押さえつけようとする力となる)されるために、屋根材が破壊されたり、固定片に形成した固定具が下地より抜け落ちない限り、屋根材が風により剥がされることがない。▲6▼垂直片が雪止めの機能を具備するために、雪止金具施工による雨漏れの心配がない。▲7▼落とし込み構造なので、雪が屋根に積もった際にはその加重により連結部がさらに強固に嵌合する構造であり、防水性、気密性が向上する。▲8▼突出片の形成により、連結部分に雪道ができ、スガ漏れによる連結部からの雨漏りがない。等の特徴、効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roofing material having an unprecedented solid feeling and workability as a roofing material, and having a waterproof function, a heat insulating function, a dew condensation preventing function, a snow stopper function, and the like.
[0002]
[Prior art]
2. Description of the Related Art In general, many roof materials obtained by processing a metal plate material by roll forming, press forming, or the like have been put on the market, and the shape has been a so-called hook structure. (For example, see Patent Documents 1 and 2). Conventionally, metal roofing materials have been receiving attention due to the relationship between vibration resistance, strength, workability, and weight. However, metal roofing materials are poor in design, and there is a risk that snow on the roof will fall easily under the eaves compared to roofing materials such as tiled roofs with large irregularities. Roof structures using roof materials with added functions have been developed. (For example, see Patent Documents 3 and 4).

[Problems to be solved by the invention]
However, since Patent Literatures 1 and 2 have a hooking structure, when used on a steeply sloping roof, the connected upper roof material falls by its own weight, so the fixing part of the upper roof material is fixed by a fixture. Until it was fixed with nails, it was necessary to hold down the roofing material by hand so that it would not fall off, and the construction was difficult. However, in the structures of Patent Literatures 3 and 4, when the upper roof material is applied to the lower roof material, the upper roof material is subjected to a bending process and the roof material is applied. For this reason, (1) poor workability, (2) difficult to construct, (3) causes rain leak if the construction is not secured, and (4) damages to the surface of the roofing material. there were.
[0005]
[Means for Solving the Problems]
In order to solve such a drawback, the present invention has a first waterproof piece having a water-side end of a decorative surface projecting upward, a fitting piece having a first waterproof piece having a tip projecting upward, A second waterproofing piece with the tip of the waterproofing piece projecting downwards, and a fixed piece with the tip of the decorative face projecting upwards above the water surface, and a vertically projecting vertical tip at the underwatering tip of the decorative face. Piece, a stepped decorative surface protruding downward, an innermost piece protruding downward near the underwater end of the decorative surface, an insertion piece protruding downward at the tip of the innermost piece, and a decorative surface And the innermost piece and the insertion piece form an engagement groove, and the width between the water upper end of the fitting piece and the water lower end of the second waterproofing piece is substantially the same as the width between the innermost piece and the stepped decorative surface. It is intended to provide a roof material formed in a length.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the roofing material according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of a roofing material A composed of a metal roofing material B and a backing material C. FIGS. 2A and 2B are explanatory views showing a construction state of the roofing material A. In the drawing, α indicates a base and β indicates a fixture such as a nail.
[0007]
The foundation α indicates a wooden foundation composed of a rafter 1, a ground board 2, and a waterproof sheet 3 (indicated by a dashed line) as shown in FIGS. 2A and 2B when newly constructed. That is, it is a groundwork α of a general structure in which the baseboard 2 is laid on the rafter 1 and the waterproof sheet 3 is provided on the baseboard 2. In addition, H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, lip channel steel, equilateral angle steel, unequal angle angle steel, square steel (square pipe), circular steel (circular pipe), It is also possible to use a steel base material using such as. Of course, when the existing roof is to be repaired as it is, the existing roof structure in which an existing roof (not shown) such as a new tile or a tile rod is formed on the ground α becomes the ground α. Of course, the base α without forming the waterproof sheet 3 may be used.
[0008]
The metal roofing material B is, for example, a metal plate (a color steel plate, a copper plate, an aluminum plate, a titanium plate, a stainless steel plate, a sandwich steel plate, a clad steel plate, or the like) formed by roll forming, press forming, extrusion forming, or the like. . Of course, instead of the metal roofing material B, the roofing material A may be formed of a ceramic material, a synthetic resin material (plastic), or the like instead of the metal roofing material B.
[0009]
More specifically, the metal roofing material B is in the shape of a long plate, and as shown in FIG. 1, the decorative surface 4, the back surface 5, and the lower end of the decorative surface projecting upward substantially in a horizontal plane. A vertical piece 6, a stepped decorative surface 6 a protruding downward, an upper surface 7 protruding inward along the step decorative surface 6 a and the decorative surface 4, and an innermost piece 8 protruding downward at a tip of the upper surface 7. A substantially U-shaped engagement groove 10 is formed from the insertion piece 9 having the tip of the innermost piece 8 protruding downward, and the upper surface 7, the innermost piece 8 and the insertion piece 9. An insertion gap 11 is formed by the engaging groove 10 to form a male connecting portion 12.
[0010]
Also, as shown in FIG. 1, the upper end of the decorative surface 4 is further protruded to the upper water side and the fixing piece 15 having the tip hanging downward is formed at the water-side end of the decorative surface 4. A first waterproof piece 13 having a lower end bent upward, an upper surface 14 having a tip of the first waterproof piece 13 protruding above the water, and an insertion piece formed in a substantially U-shaped cross section from the upper surface 14 and the fixing surface 15 9, a fitting piece 13 a with the tip of the upper surface 14 bent downward, and a second waterproof piece 13 b with the tip of the fitting piece 13 a projecting downward and upward. Thus, the female connecting portion 17 is formed.
[0011]
The vertical piece 6 has a snow stopper function and forms a hollow due to snow at the connecting portion, thereby preventing rain from leaking from the connecting portion due to suga leakage.
[0012]
The step makeup surface 6a is connected to the second waterproof piece 13b as shown in FIG. That is, at the time of fitting, the stepped decorative surface 6a collides with the distal end portion of the second waterproof piece 13b, and the second waterproof piece 13b is deformed by its own springback due to the collision force, and is firmly connected.
[0013]
Assuming that the width T between the water upper end of the fitting piece 13a and the water lower end of the second waterproofing piece 13b and the width between the innermost piece 8 and the step decorative surface 6a are t, T <t and T ≒ t (substantially equal). Therefore, they are formed to have substantially the same length. Actually, it is about t = T + (0 to 5 mm). This is a relationship necessary for the second waterproofing piece 13b to be deformed by its own springback due to its collision force and to be firmly connected to the inside of the stepped decorative surface 6a.
[0014]
The first waterproof piece 13 is a part that bends upward to add a waterproof function and also functions as a part of the fitting piece 13a.
[0015]
The second waterproofing piece 13b prevents rain and wind blowing on the roofing material A from directly blowing on the upper surface 7 of the roofing material A, and prevents the roofing material A from being peeled off by the wind. That is, as shown in FIG. 3, when the wind blows as shown by the arrow, the second waterproof piece 13b of the lower roofing material A rotates around the tip of the waterproof piece 13 as shown by the dashed-dotted arrow A by the wind. On the other hand, as shown by the dashed-dotted arrow a, the upper surface 14 acts to hold down the insertion piece 9 of the roof material A at the upper stage, and the engagement force is strengthened, and the roof material A winds. To prevent peeling.
[0016]
As described above, since the opposing forces are canceled in the connection portion between the roofing materials A, the roofing material A is not destroyed unless the roofing material A is broken or the fixing tool β formed on the fixing piece 15 falls off from the base α. Are not peeled off by the wind.
[0017]
The second waterproofing piece 13b forms a groove having a U-shaped cross section by projecting the tip of the waterproofing piece 13 to the underwater side, and the wind and rain entering by the groove are rotated in the opposite direction to be discharged. It is formed to improve waterproofness.
[0018]
The backing material C functions as a waterproofing material, a heat insulating material, a sound absorbing material, a cushioning material, a fireproofing material, a dew condensation preventing material, and the like, and includes a nonwoven fabric, a synthetic resin foam sheet (a crosslinked foamed polyethylene sheet, etc.), rock wool. , Tex (soft fiber board), rubber sheet, resin sheet, etc., or impregnated, contained, mixed, laminated (one or more layers), sandwiched, etc., with sound insulating material, refractory material, etc. You can also. In particular, the non-woven fabric is a non-woven fabric or the like in which various fibers are bonded with an adhesive or the like, unlike the conventional method in which warp and weft cross each other to convert a fiber into a fabric. In this nonwoven fabric, the fibers intersect in parallel first, or a thin felt-like material arranged randomly is bonded with an adhesive, or another thermoplastic fiber is mixed in the main fiber state, It is made by melting under heat and pressure and bonding with each other. Of course, if the material itself does not have a waterproof property, the material is coated with a resin material, or a waterproof function is added to one or both surfaces with a water repellent, a waterproof coating agent, or the like.
[0019]
The above is only one embodiment of the roofing material according to the present invention, and the roofing material A may be formed as shown in FIGS. 4 (a), (b) to 6 (a), (b). it can.
[0020]
【The invention's effect】
As described above, according to the roofing material of the present invention, (1) formation of the first waterproofing piece and the second waterproofing piece can maintain waterproofness even when the roofing material is dropped. (2) Due to the drop-in structure, even when used on a steeply sloping roof, the connected upper roof material does not fall by its own weight, and hold it by hand so that it does not fall until it is fixed The construction is easy because there is no need to install. {Circle around (3)} Since the upper end of the water on the decorative surface and the fixing piece are formed at the same level, the step may be small and there is no deformation due to the load on the connecting portion. (4) When the upper roof material is applied to the lower roof material, the second waterproof piece of the lower roof material comes into contact with the upper surface of the upper roof material, and the second waterproof piece always springs in the engagement groove. It exerts a back effect and improves waterproofness and airtightness. (5) The formation of the second waterproofing piece cancels out the opposing forces in the connection between the roofing materials (the force that tries to peel off the lower roofing material due to the wind becomes the force that tries to hold down the upper roofing material. ), The roofing material is not peeled off by the wind unless the roofing material is broken or the fixing tool formed on the fixing piece falls off the base. (6) Since the vertical piece has the function of snow stopper, there is no need to worry about rain leakage due to the construction of the snow stopper. (7) Since the structure is a drop-in structure, when snow is piled on the roof, the connection portion is further firmly fitted by the load, thereby improving waterproofness and airtightness. {Circle around (8)} Due to the formation of the projecting piece, a snowy road is formed at the connecting portion, and there is no rain leak from the connecting portion due to suga leakage. There are features and effects.
