Description

【０００１】
【発明の属する技術分野】
本発明は、化粧用凸部（例えば瓦模様）を絞り、或いは折り曲げ等で形成した薄板金属屋根板（例えばステンレス鋼板）を何枚か組み合せ、屋根を形成する際、上記屋根板の幅方向重合部より、雨水等が屋根板の裏側に回り込み屋根の下地を損傷するのを防止するようにした発明に関するものである。
【０００２】
【従来の技術】
近年、金属製の屋根板にて構成する屋根が多く施工されている。このような金属製の屋根は複数枚の屋根板を並設し、隣接する屋根板同志を重合するようにしつつ、屋根を構成してゆくものである。
即ち、屋根板同志を該屋根板の幅方向に形成した嵌合部を組み合わせて構成するものである。
この種、組み合せ式屋根で問題になるのが、屋根板同志の接続箇所重合部での水密性である。換言すると、接続の仕方によって接続部より雨水等が侵入し、屋根の下地を損傷させたり、ひどい時には室内への雨漏れにつながると言う点である。
【０００３】
以下この点を対策した従来例を図５、図６を用いて説明すると、２１ａは屋根板Ａ、この屋根板Ａは幅方向の一側に三角形状の嵌合部２２を他側に鉤状膨出部２３有している。２１ｂは屋根板Ｂ、この屋根板Ｂの幅方向の両側には、三角形状の嵌合部２２と鉤状膨出部２３を有している。２５は上記屋根板Ａ及びＢが取付けられる住宅の下地を示す、２６は弾性シール部材である。この弾性シール部材２６は図６等に示す如く、下地２５に取付けられた屋根板Ａの鉤状膨出部２３に屋根板Ｂ側の嵌合部２２を組み付けた時、両者間に出来る空間２７に上記空間を埋めるよう図に示す如く介在されるものである。
この弾性シール部材２６は、上記三角山形状の嵌合部２２に予め配設しておき、その嵌合部２２を鉤状膨出部２３に図６の如く、組み付けた時、該空間２７が図６に示す如く埋まるようにしたものである。
尚この種従来例としては、特開平０９−２５６５５７号公報がある。
【０００４】
【発明が解決しようとする課題】
かかる構成を有する従来構造の屋根板及び屋根であった場合、次の如き問題があった。
１．三角山形状の嵌合部２２に予め配設した弾性シール部材２６が該嵌合部２２の鉤状膨出部２３への取付時、間違いなく空間２７を塞ぐように充填されるかどうか判らない。
２．数十年も初期性能を確保出来る信頼性の高い弾性シール部材２６を開発する必要がある。
３．弾性シール部材２６の入った嵌合部２２への鉤状膨出部２３への取付作業が問題となることは勿論、該弾性シール部材２６を空間２７に保持する為の嵌合部２２、鉤状膨出部２３形状を作る必要があるので、屋根板Ａ、Ｂの形成が難しくなる等の問題があった。
【０００５】
【課題を解決するための手段】
本発明は、上記課題を解決すべくなされたものである。
即ち、化粧用凸部と小さな曲部を幅方向に複数列配設した薄板金属屋根板を複数枚、一部が密接するよう組み合せた屋根板及び屋根に於いて、上記屋根板Ａの幅方向一側に屋根板Ｂの化粧用凸部下側に入る重合片を設けると共に、その重合片途中に縦方向全長に亘ってくぼみを形成し、屋根板Ａ、Ｂを組み合せた時、該くぼみが水抜用溝となるようにしたものであるから毛細管現象で、屋根板ＡとＢの間に雨水等が侵入するようなことがあっても、その雨水はくぼみが作る水抜用溝に案内され水下側に流れ、隣接する屋根板Ｂ側（下地側）には回って行かないので、下地を損傷することがないものである。又くぼみが強度アップのリブの役目を果たすので重合片自体の強度アップの役目を果たすものである。
更に、屋根板Ａの縦方向全長に亘って形成したくぼみを該屋根板Ａの重合片を折り曲げて、一体に成形したものであるから、雨水等の排水の為に従来の如く特別な弾性シール部材を必要としないものである。
更に又、重合片の途中に形成されるくぼみは、重合片の高さ方向で約１／３以上高い所に形成するようにしたもので、屋根板Ａ、Ｂの密接する重合部を十分とることが出来るので毛細管現象等により雨水が、侵入するのを大幅に制限できるものである。
【０００６】
【実施例】
以下本発明の詳細を図に示す一実施例で説明する。
図１は本発明を備えた実施例を示すもので、屋根板Ａと屋根板Ｂの重合部を説明する図、図２は図１のＰ部拡大図、図３は図２とは異なる実施例を示す図でＰ部拡大相当図、図４は本発明を備えた屋根板を家屋等の屋根に実際に取付た状態を示す図である。
先ず、図１、図２に於いて、１ａは屋根板Ａ、この屋根板Ａは化粧用凸部２（例えば瓦模様）と小さな曲部３ａを幅方向に複数列設けた薄板金属板、１ｂは屋根板Ｂ、この屋根板Ｂも化粧用凸部２（例えば瓦模様）と小さな曲部３ｂを有している。
５は屋根板Ａの幅方向一側に形成された重合片、この重合片５は化粧用凸部２の略半山形状をなしている。６は上記重合片５の途中に設けられたくぼみである。又このくぼみ６は重合片５の高さ方向１／３以上の高さに設けられており、このくぼみ６の大きさは、くぼみ６中に留まる雨水等を水下側に案内されるのに十分な大きさに形成されている。３ｂは屋根板Ｂに設けられた曲部Ｂである。この曲部Ｂは屋根板Ａ側の曲部３ａを図に示す如く密着重合するよう形成されている。このように形成された屋根板Ａと屋根板Ｂを図１，図２に示す如く組み合せると、先のくぼみ６が水抜用溝８を形成する。又屋根板Ａの重合部５は屋根板Ｂの化粧用凸部の下側４に入る寸法に作られており、重合片５は化粧用凸部の裏側４に密接するものである。面して前記くぼみ６はその密着する重合片５の途中に形成されているものである。尚、先にも記述した如く、くぼみ６を重合片５の高さ方向１／３以上に設けていることより、該くぼみ６の下側の重合片５ａ及びくぼみ６より上方の重合片５ｂは屋根板Ｂの化粧用凸部裏側４と密接重合されているものである。
【０００７】
次に，図３に於いて、図３は図２に示す水抜用溝８を小さく２個に分けて形成したものであり、水抜用溝８ａ、８ｂを形成する為に屋根板Ａの重合片５の途中に２箇所くぼみ６ａ、６ｂを形成した例である。
かくの如く形成することにより、屋根板Ａと屋根板Ｂの重合部より入る雨水等が屋根の下地（後述する）側に入るのを完全に防止出来るものである。次ぎに図４に於いて、屋根板Ａ、屋根板Ｂを住宅等の屋根の下地９に組み付けた状態を説明する。
先の下地９は野地板１０，桟木１１等より構成されている。屋根板Ａ、Ｂはこの下地９に専用固定具（ネジ或いは釘、図示せず）をもって固定されている。
図４に示した屋根板Ａ、Ｂの形状は図１〜図３で示した屋根板Ａ、Ｂの形状と違っているが、図１〜図３に示すものは説明のもので実際、住宅の屋根になるのは、この図４に示す如きものである。
本図は形状こそ違っているが重合片５には、くぼみ６（図示せず）が形成されており屋根板Ａと屋根板４を組み合せた時、水抜用溝８（図示せず）が形成されている点は同じである。
かかる構成を有する屋根板及び屋根であった場合、曲部３ａと曲部３ａの重合部の隙より、毛細管現象で雨水は重合部に侵入する。曲部３ａを通り越した雨水は更に侵入し重合片５に至る。この重合片５は屋根板１ｂの化粧用凸部の裏側４に密着しているが施工時のバラツキ等で出来るわずかな隙があると、これ又毛細管現象により重合片５を上昇する。
而して、上昇した雨水は、この重合部片５の途中に形成されたくぼみ６が作る水抜用溝８に至るがそれ以上上昇するのを上記水抜用溝８がストップさせる。そしてその雨水は、その溝８に沿って水下側に流れる。このことにより重合部に侵入してきた雨水が、下地側に回り込むことがないものである。
尚、屋根板Ａと屋根板Ｂを水上側或いは、水下側に数枚配設する場合には先の水抜用溝８が水上側より水下側まで連通するように、屋根板Ａ及び屋根板Ｂを組み合せれば良いものである。
【０００８】
【発明の効果】
本発明は以上説明した如き構成を有するものであるから、特別なシール材などを使用することなく屋根板Ａと屋根板Ｂの重合部より侵入する雨水を下地側に回すことなく排水出来るものである。このことにより、原価的にも作業性的にも従来例に比較して優れた屋根板及びその屋根が得られるものである。

BACKGROUND OF THE INVENTION
In the present invention, when a roof is formed by combining several thin metal roof plates (for example, stainless steel plates) formed by drawing or bending a decorative convex portion (for example, a tile pattern), the width direction polymerization of the roof plate is performed. The present invention relates to an invention that prevents rainwater or the like from entering the back side of the roof plate from damaging the roof base.
[0002]
[Prior art]
In recent years, many roofs made of metal roof boards have been constructed. Such a metal roof constitutes a roof while arranging a plurality of roof plates side by side and overlapping adjacent roof plates.
That is, the roof boards are configured by combining the fitting portions formed in the width direction of the roof boards.
The problem with this type of combined roof is the water tightness at the overlapping portion where the roof plates are connected. In other words, rainwater or the like enters from the connection portion depending on the connection method, and damages the base of the roof or, in severe cases, leads to rain leakage into the room.
[0003]
5 and FIG. 6, a conventional example in which this point is addressed will be described below. 21 a is a roof plate A, and this roof plate A has a triangular fitting portion 22 on one side in the width direction and a bowl shape on the other side. A bulging portion 23 is provided. 21b has a roof plate B, and on both sides in the width direction of the roof plate B, a triangular fitting portion 22 and a bowl-shaped bulging portion 23 are provided. Reference numeral 25 denotes a base of a house to which the roof plates A and B are attached, and 26 is an elastic seal member. As shown in FIG. 6 and the like, the elastic seal member 26 has a space 27 between the two when the fitting portion 22 on the roof plate B side is assembled to the flange-like bulged portion 23 of the roof plate A attached to the base 25. As shown in the figure, it is interposed so as to fill the space.
This elastic seal member 26 is disposed in advance in the triangular mountain-shaped fitting portion 22, and when the fitting portion 22 is assembled to the bowl-shaped bulging portion 23 as shown in FIG. It is embedded as shown in FIG.
As a conventional example of this kind, there is Japanese Patent Application Laid-Open No. 09-256557.
[0004]
[Problems to be solved by the invention]
In the case of the conventional roof plate and roof having such a configuration, there are the following problems.
1. Whether or not the elastic seal member 26 previously disposed in the triangular mountain-shaped fitting portion 22 is filled so as to close the space 27 without fail when the fitting portion 22 is attached to the bowl-shaped bulging portion 23 is unknown. .
2. It is necessary to develop a highly reliable elastic seal member 26 that can ensure initial performance for several decades.
3. The fitting work for holding the elastic seal member 26 in the space 27 is, of course, not only the problem of the mounting work to the flange-like bulging part 23 to the fitting part 22 containing the elastic seal member 26. Since it is necessary to make the shape of the bulged portion 23, there is a problem that it is difficult to form the roof plates A and B.
[0005]
[Means for Solving the Problems]
The present invention has been made to solve the above problems.
That is, in the roof plate and the roof in which a plurality of thin metal roof plates having a plurality of decorative convex portions and small curved portions arranged in the width direction are combined in close contact with each other, the width direction of the roof plate A A polymer piece entering the lower side of the decorative convex portion of the roof panel B is provided on one side, and a depression is formed in the middle of the polymerization piece over the entire length in the longitudinal direction. When the roof sheets A and B are combined, the depression is drained. Even if rainwater or the like may invade between the roof plates A and B due to capillary action, the rainwater is guided to the drainage groove created by the indentation. Since it flows to the side and does not turn to the adjacent roofboard B side (base side), the base is not damaged. Moreover, since the depression serves as a rib for increasing the strength, it serves to increase the strength of the polymer piece itself.
Furthermore, since the hollow formed over the entire length in the longitudinal direction of the roof plate A is formed by bending the overlapping piece of the roof plate A and integrally forming it, a special elastic seal is conventionally used for draining rainwater and the like. A member is not required.
Furthermore, the depression formed in the middle of the polymer piece is formed at a place higher by about 1/3 or more in the height direction of the polymer piece, and a sufficient overlap portion of the roof plates A and B is taken sufficiently. Therefore, it is possible to greatly limit the invasion of rainwater by capillarity or the like.
[0006]
【Example】
Details of the present invention will be described below with reference to an embodiment shown in the drawings.
FIG. 1 shows an embodiment provided with the present invention. FIG. 2 is a diagram for explaining the overlapping portion of the roof plate A and the roof plate B, FIG. 2 is an enlarged view of a P portion of FIG. 1, and FIG. FIG. 4 is a diagram showing an example of an enlarged view corresponding to a portion P, and FIG. 4 is a diagram showing a state in which a roof plate provided with the present invention is actually attached to a roof such as a house.
First, in FIGS. 1 and 2, 1a is a roof plate A, and this roof plate A is a thin metal plate 1b having a plurality of rows of decorative convex portions 2 (for example, a tile pattern) and small curved portions 3a provided in the width direction. Is a roof plate B, and this roof plate B also has a decorative convex portion 2 (for example, a tile pattern) and a small curved portion 3b.
Reference numeral 5 denotes a polymerized piece formed on one side in the width direction of the roof plate A, and this polymerized piece 5 has a substantially half-mountain shape of the decorative convex portion 2. Reference numeral 6 denotes a recess provided in the middle of the polymer piece 5. The depression 6 is provided at a height of 1/3 or more of the height direction of the polymer piece 5, and the size of the depression 6 is to guide rainwater or the like remaining in the depression 6 to the lower side. It is formed in a sufficient size. Reference numeral 3b denotes a curved portion B provided on the roof plate B. The curved portion B is formed so as to closely polymerize the curved portion 3a on the roof plate A side as shown in the figure. When the roof plate A and the roof plate B formed in this way are combined as shown in FIGS. 1 and 2, the recess 6 forms a draining groove 8. The overlap portion 5 of the roof plate A is sized to enter the lower side 4 of the decorative convex portion of the roof plate B, and the overlap piece 5 is in close contact with the back side 4 of the decorative convex portion. Faced, the recess 6 is formed in the middle of the adhering polymer piece 5. As described above, since the depression 6 is provided at 1/3 or more in the height direction of the polymerization piece 5, the polymerization piece 5 a below the depression 6 and the polymerization piece 5 b above the depression 6 are This is intimately polymerized with the decorative convex rear side 4 of the roof panel B.
[0007]
Next, in FIG. 3, FIG. 3 shows that the draining groove 8 shown in FIG. 2 is divided into two small parts, and the overlapping pieces of the roof plate A are formed to form the draining grooves 8a and 8b. 5 is an example in which two recesses 6a and 6b are formed in the middle.
By forming in this way, it is possible to completely prevent rainwater or the like entering from the overlapping portion of the roof plate A and the roof plate B from entering the base (described later) side of the roof. Next, referring to FIG. 4, a state in which the roof board A and the roof board B are assembled to the base 9 of the roof of a house or the like will be described.
The previous base 9 is composed of a base plate 10, a pier 11 and the like. The roof plates A and B are fixed to the base 9 with dedicated fixing tools (screws or nails, not shown).
Although the shape of the roof boards A and B shown in FIG. 4 is different from the shape of the roof boards A and B shown in FIGS. 1 to 3, the ones shown in FIGS. The roof becomes as shown in FIG.
Although this figure is different in shape, a depression 6 (not shown) is formed on the polymer piece 5 and when the roof plate A and the roof plate 4 are combined, a draining groove 8 (not shown) is formed. The point is the same.
In the case of the roof plate and the roof having such a configuration, rainwater enters the superposed portion by capillary action through the gap between the curved portion 3a and the superposed portion of the curved portion 3a. Rainwater that has passed through the curved portion 3 a further enters and reaches the polymer piece 5. The polymer piece 5 is in close contact with the back side 4 of the decorative convex portion of the roof plate 1b. However, if there is a slight gap due to variations during construction, the polymer piece 5 also rises due to capillary action.
Thus, the rainwater that has risen reaches the drainage groove 8 formed by the recess 6 formed in the middle of the overlapping part 5 but the drainage groove 8 stops further rising. Then, the rainwater flows downward along the groove 8. As a result, rainwater that has entered the superposition part does not wrap around the base side.
In addition, when several roof boards A and B are arranged on the water side or on the water side, the roof board A and the roof are arranged so that the water draining groove 8 communicates from the water side to the water side. What is necessary is just to combine the board B.
[0008]
【The invention's effect】
Since the present invention has the configuration as described above, it is possible to drain rainwater entering from the overlapping portion of the roof plate A and the roof plate B without using a special sealing material or the like without turning to the ground side. is there. As a result, an excellent roof plate and its roof can be obtained in terms of cost and workability as compared with the conventional example.
