Description

本発明は、勾配屋根面上に、瓦型太陽電池パネルと波形瓦とを一緒に葺き上げる屋根葺き構造に関する。   The present invention relates to a roofing structure in which tile-type solar panels and corrugated tiles are rolled up on a sloped roof surface.

近年、屋根に太陽電池パネル（太陽電池モジュール）を設置する建物が増加している。その種の建物のうち、とくに瓦葺きの勾配屋根を有する住宅等にあっては、例えば特許文献１に開示されているように、瓦と同程度の厚さの平板状に形成した瓦型太陽電池パネルを、通常の瓦と一緒に葺き上げる屋根葺き構造がよく採用されている。瓦型太陽電池パネルは一般的に、ガラス製のセルをアルミ型材からなる枠体で囲った構成になっており、その枠体は瓦を横方向に数枚分並べた大きさに形成されている。そして、下段の瓦又は瓦型太陽電池パネルの水上側縁部に、上段の瓦又は瓦型太陽電池パネルの水下側縁部を被せるようにして階段状に葺き上げられる。   In recent years, an increasing number of buildings have solar cell panels (solar cell modules) installed on the roof. Among such buildings, particularly in a house having a tiled sloped roof, for example, as disclosed in Patent Document 1, a tile-type solar cell formed into a flat plate having the same thickness as a tile. A roofing structure is often used in which panels are rolled up with normal tiles. A tile-type solar cell panel generally has a structure in which a glass cell is surrounded by a frame made of an aluminum-type material, and the frame is formed in a size in which several tiles are arranged in a horizontal direction. Yes. Then, the upper tile of the lower tile or the tile-shaped solar cell panel is rolled up stepwise so as to cover the lower edge of the upper tile or the tile-shaped solar cell panel.

この種の屋根葺き構造では、瓦と瓦型太陽電池パネルとの葺き重ね部分の水密性を確保するために、全体が略平坦な形状の平板瓦が用いられている。平板瓦は、工業化住宅用の屋根瓦としても広く利用されている種類の瓦であり、日本工業規格（ＪＩＳ）Ａ５２０８「粘土かわら」（１９９６）には「Ｆ形」という名称で、その基本的形状が規定されている。   In this type of roofing structure, flat roof tiles having a substantially flat shape as a whole are used in order to ensure the watertightness of the overlapped portion between the tiles and the tile-type solar cell panels. Flat roof tiles are a type of roof tile that is also widely used as roof tiles for industrialized houses. The Japanese Industrial Standard (JIS) A5208 “Clay Kawara” (1996) is called “F type” and its basics. The shape is specified.

ＪＩＳハンドブック（８）建築Ｉ 材料・設備 ２０１１年版 財団法人日本規格協会発行JIS Handbook (8) Architecture I Materials and Equipment 2011 Edition Published by Japanese Standards Association

屋根葺き材は、建物の様式や趣味嗜好に応じて選択され、建物の外観意匠を大きく左右する造形要素である。瓦にも様々な形状のものがあるが、例えば屋根面の重厚間を強調したい古典的な様式の建物では、山谷起伏の大きい波形瓦が好まれることが多い。   The roofing material is a modeling element that is selected according to the style of the building and the taste and taste, and greatly affects the exterior design of the building. There are various types of tiles, but for example, a classic style building that emphasizes the heavyness of the roof surface is often favored by corrugated tiles with large mountain valley relief.

波形瓦の代表的なものは、前記ＪＩＳにおいて、「Ｊ形」、「Ｓ形」という名称で、その基本的形状が規定されている。「Ｊ形」は、日本の伝統的建築に採用されてきた本瓦（平瓦と丸瓦）を簡略一体化したもので、近世以降、現在まで、日本国内における最も一般的な瓦屋根用の和風桟瓦として普及している。「Ｓ形」は、西洋風建築に採用されてきたスパニッシュ瓦を、Ｊ形と同様に簡略一体化したＳ字状の洋風桟瓦である。これらの波形瓦はいずれも、瓦の幅方向における片側略半部に山部、他側略半部に谷部がそれぞれ形成された左右非対称の断面形状を有している。   As for typical corrugated roof tiles, the basic shapes of the corrugated roof tiles are defined by the names “J shape” and “S shape” in the JIS. “J-shape” is a simple integration of the main roof tiles (flat roof tiles and round roof tiles) that have been adopted in traditional Japanese architecture. For the most common tile roofs in Japan since the early modern times. It is popular as a Japanese style roof tile. The “S-shape” is an S-shaped western-style roof tile obtained by simply integrating the Spanish roof tiles that have been adopted in Western-style architecture in the same manner as the J-shape. Each of these corrugated roof tiles has a left-right asymmetric cross-sectional shape in which a crest is formed in a substantially half portion on one side and a trough is formed in a substantially half portion on the other side in the width direction of the roof tile.

ところが、Ｊ形やＳ形のような形状の波形瓦と瓦型太陽電池パネルとを一緒に葺き上げようとしても、山谷起伏を有する波形瓦と平板状の瓦型太陽電池パネルとの葺き重ね部分の水密性を確保するのが難しい。そのため、現状ではもっぱら平板瓦が利用されており、その結果、瓦型太陽電池パネルを葺設する屋根の造形的印象は平坦で単調になりがちである。また、波形瓦は通常、横方向の葺き重ね部（目地）を流れ方向に揃える葺き方（本明細書においては、説明の便宜上、これを「筋葺き」と呼ぶ。）で葺設されるが、一般論としては、葺き重ね部（目地）の位置を一段ごとに瓦幅の半分だけずらす葺き方（本明細書においては、これを「千鳥葺き」と呼ぶ。）のほうが、筋葺きに比べて防水性（排水性）や耐風性の面で有利であるとされている。しかし、大きい山谷起伏が設けられた左右非対称かつ非合同の断面形状を有する波形瓦を千鳥葺きしようとすると、当然ながら山谷起伏の流れ方向における連続性が互い違いにずれてしまう。 However, even when trying to roll up the corrugated roof tile and the roof tile solar cell panel in the shape of J shape or S shape, the overlapping portion of the corrugated roof tile with the hills and valleys and the flat roof tile solar panel It is difficult to ensure water tightness. Therefore, at present, flat roof tiles are exclusively used, and as a result, the impression of the roof on which the roof tile-type solar panel is installed tends to be flat and monotonous. In addition, the corrugated roof tiles are usually laid out by a method of squeezing the laterally stacked portions (joints) in the flow direction (in this specification, for convenience of explanation, this is referred to as “streak”). As a general rule, the method of slashing the position of the laying-up portion (joint) by half of the roof tile width for each step (in this specification, this is referred to as “staggered”) compared to the streaking. Therefore, it is said to be advantageous in terms of waterproofness (drainage) and wind resistance. However, when trying to stagger corrugated roof tiles having an asymmetrical and incongruent cross-sectional shape provided with large mountain valley relief, naturally the continuity in the flow direction of the mountain valley relief is staggered.

本発明は、かかる事情に鑑みてなされたもので、Ｊ形やＳ形のように大きい山谷起伏を有する波形瓦と、平板状の瓦型太陽電池パネルとを、千鳥葺きで一緒に葺き上げることのできる屋根葺き構造を提供するものである。 The present invention has been made in view of such circumstances, and corrugated roof tiles having large ridges and valleys, such as J-shape and S-shape, and a flat roof tile-type solar cell panel are strewn together in a staggered manner. It provides a roofing structure that can be used.

前述の目的を達成するため、本発明の屋根葺き構造は、幅方向における片側略半部に山部、他側略半部に谷部がそれぞれ形成された非対称断面の波形瓦と、矩形の平板形状を有する瓦型太陽電池パネルとを、勾配屋根面上に葺設する屋根葺き構造であって、前記波形瓦には、流れ方向の水下側から水上側に向かって左側に谷部、右側に山部が形成された「谷山タイプ」の波形瓦と、左側に山部、右側に谷部が形成された「山谷タイプ」の波形瓦との２種類が用意され、前記「谷山タイプ」の波形瓦、及び前記「山谷タイプ」の波形瓦のいずれも、幅方向における同じ側にアンダーラップ部が張り出し、他側には前記アンダーラップ部に重なるオーバーラップ部が形成されるとともに、水上側縁部には山部を削ぎ落として谷部の上部を埋めた形状の平坦なパネル受部が形成される一方、水下側縁部には底辺が一直線状をなす垂面部が形成されて、屋根面の一段ごとに、ひとつの段には前記「谷山タイプ」の波形瓦が一定方向に葺き重ねられ、その上段には前記「山谷タイプ」の波形瓦が前記下段の葺き重ね方向と同じ方向に葺き重ねられることにより、波形瓦の山部及び谷部を流れ方向に揃えつつ、各段の葺き重ね部が千鳥となるように波形瓦が葺設されるとともに、前記波形瓦と少なくとも１枚の前記瓦型太陽電池パネルとが取り合う部位については、瓦型太陽電池パネルの水下側の段に葺設された波形瓦のパネル受部の上に瓦型太陽電池パネルの水下側縁部が葺き重ねられ、瓦型太陽電池パネルの水上側縁部の上に、更にその水上側の段に葺設される波形瓦の垂面部が葺き重ねられる、との構成を採用するものである。 In order to achieve the above-described object, the roofing structure of the present invention includes a corrugated roof tile having an asymmetric cross-section in which a crest is formed in a substantially half on one side and a trough is formed in a substantially half on the other side, and a rectangular flat plate. A roofing structure in which a tile-shaped solar panel having a shape is installed on a sloped roof surface, wherein the corrugated tile has a trough on the left side and a right side from the water side in the flow direction toward the water side. There are two types of corrugated roof tiles, “Taniyama type”, and “Yamaya type” corrugated roof tiles on the left and on the right. Both the corrugated roof tiles and the “mountain valley type” corrugated roof tiles have an underlap projecting on the same side in the width direction, and an overlap section is formed on the other side so as to overlap the underlap section. In the part, the mountain part is cut off and the upper part of the valley part is buried A flat panel receiving portion is formed on the lower side edge, and a vertical surface portion is formed on the bottom edge of the water, the bottom of which is a straight line. Corrugated roof tiles are stacked in a certain direction, and the upper part of the corrugated roof tiles are stacked in the same direction as the lower stacking direction of the corrugated roof tile. As for the portion where the corrugated roof tile and the at least one roof tile solar cell panel meet, the roof tile solar cell is arranged so that the corrugated roof tiles are staggered in each stage. The bottom edge of the tile-type solar panel is rolled up on the corrugated tile panel receiving part installed on the bottom side of the panel, and the top edge of the tile-type solar panel is above the water-side edge. In addition, the vertical surface of corrugated roof tiles installed on the upper water level That is intended to adopt a configuration with.

このように、瓦型太陽電池パネルとの葺き重ね部分に葺設される波形瓦の水下側縁部及び水上側縁部に、瓦型太陽電池パネルとの取り合いを考慮した形状的工夫を施すことにより、波形瓦と瓦型太陽電池パネルとの葺き重ね部分の水密性が好適に確保される。 Thus, the Underwater side edge and water side edge of the waveform tile to be葺設the roofing overlapped portion between the roof tile solar cell panels, subjected to shape contrivance Considering scramble for the tile type solar panel Thereby, the watertightness of the overlapping part of the corrugated roof tile and the roof tile-type solar cell panel is suitably secured.

また、この波形瓦は、瓦型太陽電池パネルの水下側及び水上側、さらに瓦型太陽電池パネルとは接しない一般部も含めて、屋根面略全体（棟際や隅谷などの特殊部位を除く）の葺き上げに利用することができる。 In addition, this corrugated roof tile covers almost the entire roof surface (including special parts such as the ridges and corners), including the lower and upper sides of the roof tile solar panel and the general part that is not in contact with the roof tile solar panel. Can be used to raise

さらに、流れ方向の水下側から水上側に向かって左側に谷部、右側に山部が形成された「谷山タイプ」の波形瓦と、左側に山部、右側に谷部が形成された「山谷タイプ」の波形瓦との２種類を用意して、屋根面の一段ごとに、ひとつの段には前記「谷山タイプ」の波形瓦を一定方向に葺き重ね、その上段には前記「山谷タイプ」の波形瓦を前記下段の葺き重ね方向と同じ方向に葺き重ねるという葺き方を採用することにより、波形瓦の断面形状が左右非対称かつ非合同の山谷起伏を有する場合でも、波形瓦の山部及び谷部を流れ方向に揃えつつ、波形瓦と瓦型太陽電池パネルとを千鳥葺きすることが可能になる。 In addition, the valleys on the left side of the water side of the water under side of the flow Re direction, and waveform tile mountain portion is formed on the right side "Taniyama Type", crests, valleys are formed in the right to left was to prepare two types of the waveform tile of "Sanya type", for each stage of the roof surface, heavy thatched waveform tile of the "Taniyama type" in a certain direction in one of the stage, said in its upper stage by adopting how thatched that the waveform tile Ru overlaid roofing in the same direction as the roofing overlapping direction of the lower "Yamaya type", even when the cross-sectional shape of the waveform tile having a peak to valley undulation of asymmetrical and non-congruent, waveform It is possible to stagger the corrugated roof tiles and the roof tile-type solar panel while aligning the peak and valley portions of the roof tiles in the flow direction .

また、この屋根葺き構造は、前記波形瓦の幅方向における同じ側にアンダーラップ部が張り出し、他側には前記アンダーラップ部に重なるオーバーラップ部が形成されているので、横方向の葺き重ね部分も水密性が好適に確保される。 Further, this roofing structure has an overlap portion extending on the same side in the width direction of the corrugated tile , and an overlap portion is formed on the other side so as to overlap the underlap portion. In addition, water tightness is preferably ensured.

本発明の屋根葺き構造は、「谷山タイプ」の波形瓦と「山谷タイプ」の波形瓦との２種類を用意し、屋根面の一段ごとに、どちらか一方の波形瓦を一定方向に葺き重ね、その上段には他方の波形瓦を同じ方向に葺き重ねるという葺き方を採用しているので、波形瓦の断面形状が左右非対称かつ非合同の山谷起伏を有する場合でも、波形瓦の山部及び谷部を流れ方向に揃えながら千鳥葺きすることができる。さらに、瓦型太陽電池パネルとの葺き重ね部分に葺設される波形瓦の水下側縁部及び水上側縁部に、瓦型太陽電池パネルとの取り合いを考慮した形状的工夫を施しているので、波形瓦と瓦型太陽電池パネルとの葺き重ね部分の水密性が好適に確保される。これにより、瓦型太陽電池パネルを平板瓦と一緒に葺き上げていた従来の屋根よりも、波形瓦の山谷起伏を強調した、重厚感や立体感のある屋根を施工することができる。 The roofing structure of the present invention is prepared with two types of corrugated roof tiles of “Taniyama type” and corrugated roof tiles of “Taniyama type”, and one of the corrugated roof tiles is stacked in a certain direction for each step of the roof surface. In the upper stage, the method of rolling the other corrugated roof tiles in the same direction is adopted, so even when the corrugated roof cross-sectional shape has asymmetrical and uneven mountain valley undulations, You can stagger while aligning the valleys in the flow direction. Furthermore, the shape of the corrugated roof tiles that are installed in the overlapping area with the roof tile-type solar cell panel is devised in consideration of the contact with the roof tile-type solar battery panel. Therefore, the water tightness of the overlapping portion of the corrugated roof tile and the tile-shaped solar cell panel is suitably ensured. Thereby, rather than the conventional roof which rolled up the tile-shaped solar cell panel with the flat tile, the roof with a solid feeling and a three-dimensional feeling which emphasized the undulation of the corrugated tile can be constructed.

例示形態にあっては、３種類の波形瓦１（１Ａ、１Ｂ、１Ｃ）と、波形瓦１を横方向に４枚分並べた大きさの平坦な瓦型太陽電池パネル２とが、葺き重ね部（目地）の位置を流れ方向（図１における下向き）に揃えて葺設されている。このように、隣り合う屋根葺き材同士の葺き重ね部を流れ方向に揃える葺き方を、本明細書においては説明の便宜上、「筋葺き」と呼ぶ。   In the illustrated embodiment, three types of corrugated roof tiles 1 (1A, 1B, 1C) and a flat roof tile-type solar cell panel 2 having a size in which four corrugated roof tiles 1 are arranged in the horizontal direction are rolled up and stacked. The position of the part (joint) is provided so as to be aligned with the flow direction (downward in FIG. 1). In this specification, for the sake of convenience of description, the method of aligning the overlapping portions of the adjacent roofing materials in the flow direction is referred to as “stitching”.

例示の波形瓦１（１Ａ、１Ｂ、１Ｃ）は、ＪＩＳのＳ形に準じたもので、流れ方向の水下側から水上側に向かって左側に谷部３、右側に山部４がそれぞれ形成された左右非対称かつ非合同の断面形状を有している。図１では、山谷の並びを分かりやすくするために、各波形瓦の山部４の位置に薄網を付している。（図１では山部４を長方形で表しているが、実際には山部４が上下で重なり合うため、各山部４は水下側に向かってやや拡幅する扇形になる。）
図２の（１）に示した波形瓦１Ａは、瓦型太陽電池パネル２と流れ方向に重ならない一般部、すなわち瓦型太陽電池パネル２の横方向に連なる部位、及び瓦型太陽電池パネル２とは全く接しない部位に葺設される瓦である。この一般部用瓦は、従来一般のＳ形瓦と同様に水下側の端面が湾曲しており、谷部３の水上側縁部には水返し５が立ち上げられ、その近傍に２ヶ所程度の釘孔６が形成されている。 The illustrated corrugated roof tile 1 (1A, 1B, 1C) conforms to the JIS S shape, and a valley portion 3 is formed on the left side and a mountain portion 4 is formed on the right side from the water side to the water side in the flow direction. It has a left-right asymmetric and non-congruent cross-sectional shape. In FIG. 1, a thin net is attached to the position of the peak portion 4 of each corrugated roof tile in order to make the arrangement of the peaks and valleys easy to understand. (In FIG. 1, the ridges 4 are represented by rectangles. However, since the ridges 4 overlap each other in the upper and lower sides, each ridge 4 has a fan shape that slightly widens toward the water side.)
The corrugated roof tile 1A shown in (1) of FIG. 2 is a general portion that does not overlap with the roof tile solar cell panel 2 in the flow direction, that is, a portion that continues in the lateral direction of the roof tile solar cell panel 2, and the roof tile solar cell panel 2. Is a roof tile installed in a part that does not touch at all. This general roof tile has a curved end face on the underwater side in the same way as a conventional general S-shaped roof tile. A nail hole 6 of a degree is formed.

図２の（２）に示した波形瓦１Ｂは、瓦型太陽電池パネル２の水下側に葺設される役物瓦である。この役物瓦の水上側縁部には、瓦の幅方向にわたって平坦なパネル受部７が形成されている。パネル受部７は、水上側縁部から流れ方向における所定寸法の範囲内で、水上側縁部と平行に山部４の上部を削ぎ落とすとともに、谷部３の上部を埋めた形状をなしている。パネル受部７の水上側縁部には、一直線状に延びる水返し５が一般部用瓦と同じように立ち上げられるとともに、その近傍に２ヶ所程度の釘孔６が形成されている。   A corrugated roof tile 1 </ b> B shown in (2) of FIG. 2 is an accessory roof tile provided on the underwater side of the roof tile-type solar cell panel 2. A flat panel receiving portion 7 is formed on the water-side edge portion of the tile tile in the width direction of the tile. The panel receiving part 7 has a shape in which the upper part of the mountain part 4 is scraped off in parallel with the water upper edge part and the upper part of the valley part 3 is buried within a predetermined dimension in the flow direction from the water upper edge part. Yes. On the water-side edge of the panel receiving portion 7, a water return 5 extending in a straight line is raised in the same manner as the general roof tile, and two nail holes 6 are formed in the vicinity thereof.

パネル受部７から山部４に連続する面には、その隅に雨水が溜まるのを防ぐために、図３及び図４に示すような上面視三角形状の分水嶺８が形成されている。また、パネル受部７から谷部３に連続する面９もなだらかに傾斜した弓形状をなしている。 In order to prevent rainwater from accumulating at the corners, a water divide 8 having a triangular shape as viewed from above is formed on the surface continuous from the panel receiving portion 7 to the mountain portion 4. Further, the surface 9 continuing from the panel receiving portion 7 to the valley portion 3 also has a gently sloping bow shape.

図２の（３）に示した波形瓦１Ｃは、瓦型太陽電池パネル２の水上側に葺設される役物瓦である。この役物瓦の水下側縁部には、底辺が一直線状をなす垂面部１０が形成されている。垂面部１０は、山部４の水下側開口面を塞ぐようにして、山部４及び谷部３の水下側縁部から流れ方向と略直交する向きに延設されており、その底辺は、谷部３の最も低い中央部分の裏面とほぼ同じ高さに揃えられている。この役物瓦においても、谷部３の水上側縁部には一般部用瓦と同様の水返し５が立ち上げられ、その近傍に２ヶ所程度の釘孔６が形成されている。   A corrugated roof tile 1 </ b> C shown in (3) of FIG. 2 is an accessory roof tile provided on the water side of the roof tile-type solar cell panel 2. A vertical surface portion 10 having a straight base is formed at the water-side edge of the accessory tile. The vertical surface portion 10 extends from the water-side edge of the mountain portion 4 and the valley portion 3 in a direction substantially orthogonal to the flow direction so as to block the water-side opening surface of the mountain portion 4, and its bottom side Are arranged at almost the same height as the back surface of the lowest central portion of the valley 3. Also in this accessory roof tile, the water return 5 similar to the roof tile for the general section is raised at the water-side edge of the valley section 3, and two nail holes 6 are formed in the vicinity thereof.

これら一般部用瓦（波形瓦１Ａ）及び役物瓦（波形瓦１Ｂ、波形瓦１Ｃ）のいずれも、瓦全体の実質的な利き幅（働き幅）及び利き足（働き長さ）は共通で、谷部３及び山部４それぞれの幅方向における湾曲形状や流れ方向における傾斜形状も共通である。そして、従来一般のＦ形瓦と同様に、いずれのタイプも、水下側から水上側に向かって左側の縁部に数センチ幅のアンダーラップ部１１が張り出しており、右側の縁部には、前記アンダーラップ部１１に重なるオーバーラップ部１２が形成されている。   Both the general-purpose roof tile (corrugated roof tile 1A) and the accessory tile (corrugated roof tile 1B, corrugated roof tile 1C) have the same substantial dominant width (working width) and dominant foot (working length). The curved shape in the width direction and the inclined shape in the flow direction of the valley portion 3 and the mountain portion 4 are also common. And, like the conventional general F-shaped roof tiles, in each type, an underlap portion 11 having a width of several centimeters protrudes from the underwater side to the upper side of the water, and the right edge portion An overlap portion 12 that overlaps the underlap portion 11 is formed.

波形瓦１（１Ａ、１Ｂ、１Ｃ）と瓦型太陽電池パネル２は、屋根面の各段において、アンダーラップ部１１の向きに合わせて右側から左側へと順次、葺き重ねられる。波形瓦１Ａと瓦型太陽電池パネル２とが横方向に取り合う部位は、図５に示すように、波形瓦１Ａのアンダーラップ部１１の上に瓦型太陽電池パネル２の右枠材１３が載り、また、瓦型太陽電池パネル２の左枠材１４に延設された瓦受部１５の上に波形瓦１Ａのオーバーラップ部１２が載るようにして葺き重ねられる。   The corrugated roof tiles 1 (1A, 1B, 1C) and the roof tile-type solar battery panel 2 are sequentially stacked from the right side to the left side in accordance with the direction of the underlap portion 11 in each step of the roof surface. The part where the corrugated roof tile 1A and the roof tile solar cell panel 2 meet in the horizontal direction is such that the right frame member 13 of the roof tile solar cell panel 2 is placed on the underlap portion 11 of the corrugated roof tile 1A as shown in FIG. In addition, the corrugated roof tile 1A is overlapped so that the overlap section 12 of the corrugated roof tile 1A is placed on the roof tile receiving section 15 extending from the left frame member 14 of the roof tile-type solar cell panel 2.

また、流れ方向については図４に示すように、瓦型太陽電池パネル２の水下側に葺設される役物瓦（波形瓦１Ｂ）のパネル受部７が、屋根下地上１６に配設した瓦桟１７に釘等で打ちつけられ、その上に瓦型太陽電池パネル２の水下側枠材１８が載り、さらに、瓦型太陽電池パネル２の水上側枠材１９の上に水上側の役物瓦（波形瓦１Ｃ）の垂面部１０が載るようにして葺き重ねられる。   As for the flow direction, as shown in FIG. 4, the panel receiving portion 7 for the functional tile (corrugated tile 1 </ b> B) installed on the underside of the tile-type solar cell panel 2 is disposed on the roof base 16. The roof frame 17 is nailed with a nail or the like, and the underwater frame member 18 of the tile type solar cell panel 2 is placed thereon. The vertical surface 10 of the accessory tile (corrugated roof tile 1C) is rolled up so as to be placed thereon.

こうして、四周が平坦な形状の瓦型太陽電池パネル２と、山谷起伏を有する波形瓦１（１Ａ、１Ｂ、１Ｃ）とが、互いの取り合い部分を水密的に封止した状態で一体的に葺設されることとなる。   Thus, the tile-shaped solar cell panel 2 having a flat shape on all four sides and the corrugated roof tiles 1 (1A, 1B, 1C) having the undulations of the valleys and valleys are integrally formed in a state where the mutual connection portions are sealed in a watertight manner. Will be established.

図６に示した波形瓦１Ｄは、本発明の屋根葺き構造に用いられる波形瓦の構成例を示すものである。この波形瓦１Ｄは、前述した３種類の波形瓦１（１Ａ、１Ｂ、１Ｃ）の機能的特徴を一体化したものである。 The corrugated tile 1D shown in FIG. 6 shows a configuration example of the corrugated tile used in the roofing structure of the present invention . This corrugated roof tile 1D is obtained by integrating the functional characteristics of the three types of corrugated roof tiles 1 (1A, 1B, 1C) described above.

すなわち、この波形瓦１Ｄは、ＪＩＳのＳ形に準じて、流れ方向の水下側から水上側に向かって左側に谷部３、右側に山部４がそれぞれ形成された左右非対称かつ非合同の断面形状を有している。   That is, this corrugated roof tile 1D is asymmetrical and incongruent in the left-right direction in which the valley portion 3 is formed on the left side and the peak portion 4 is formed on the right side from the water side in the flow direction toward the water side in accordance with JIS S shape. It has a cross-sectional shape.

波形瓦１Ｄの水上側縁部には、瓦型太陽電池パネル２の水下側に葺設される役物瓦（波形瓦１Ｂ）と同様に、瓦の幅方向にわたって平坦なパネル受部７が形成されている。パネル受部７は、水上側縁部から流れ方向における所定寸法の範囲内で、水上側縁部と平行に山部４の上部を削ぎ落とすとともに、谷部３の上部を埋めた形状をなしている。パネル受部７の水上側縁部には、一直線状に延びる水返し５が立ち上げられるとともに、その近傍に２ヶ所程度の釘孔６が形成されている。パネル受部７から山部４に連続する面には、その隅に雨水が溜まるのを防ぐため、波形瓦１Ｂと同様の分水嶺（図示せず）が形成されている。また、パネル受部７から谷部３に連続する面９はなだらかに傾斜した弓形状をなしている。 A panel receiving portion 7 that is flat across the width direction of the roof tile is formed on the water-side edge of the corrugated roof tile 1D, as in the case of the tile roof tile (the corrugated roof tile 1B) provided on the water bottom side of the roof tile-type solar cell panel 2. Is formed. The panel receiving part 7 has a shape in which the upper part of the mountain part 4 is scraped off in parallel with the water upper edge part and the upper part of the valley part 3 is buried within a predetermined dimension in the flow direction from the water upper edge part. Yes. A water return 5 extending in a straight line is raised at the water-side edge of the panel receiving portion 7, and two nail holes 6 are formed in the vicinity thereof. In order to prevent rainwater from accumulating at the corners, a water divide (not shown) similar to the corrugated roof tile 1B is formed on the surface continuous from the panel receiving part 7 to the mountain part 4. Further, the surface 9 continuing from the panel receiving portion 7 to the valley portion 3 has a gently inclined bow shape.

波形瓦１Ｄの水下側縁部には、瓦型太陽電池パネル２の水上側に葺設される役物瓦（波形瓦１Ｃ）と同様に、底辺が一直線状をなす垂面部１０が形成されている。垂面部１０は、山部４の水下側開口面を塞ぐようにして、山部４及び谷部３の水下側縁部から流れ方向と略直交する向きに延設されており、その底辺は、谷部３の最も低い中央部分の裏面とほぼ同じ高さに揃えられている。   A vertical surface 10 is formed on the bottom edge of the corrugated roof tile 1D in the same manner as the accessory roof tile (the corrugated roof tile 1C) provided on the water top side of the roof tile-type solar cell panel 2. ing. The vertical surface portion 10 extends from the water-side edge of the mountain portion 4 and the valley portion 3 in a direction substantially orthogonal to the flow direction so as to block the water-side opening surface of the mountain portion 4, and its bottom side Are arranged at almost the same height as the back surface of the lowest central portion of the valley 3.

このような形状を有する波形瓦１Ｄは、瓦型太陽電池パネル２の水下側縁部及び水上側縁部のいずれにも葺設することができる。   The corrugated roof tile 1 </ b> D having such a shape can be installed on both the underwater side edge and the overwater edge of the roof tile solar cell panel 2.

波形瓦１Ｄと瓦型太陽電池パネル２とが横方向及び流れ方向に取り合う部位の断面は、図５及び図４に示した形態に準じる。すなわち、波形瓦１Ｄのアンダーラップ部１１の上に瓦型太陽電池パネル２の右枠材１３が載り、また、瓦型太陽電池パネル２の左枠材１４に延設された瓦受部１５の上に波形瓦１Ｄのオーバーラップ部１２が載る。また、流れ方向については、瓦型太陽電池パネル２の水下側に葺設される波形瓦１Ｄのパネル受部７が、屋根下地上１６に配設した瓦桟１７に釘等で打ちつけられ、その上に瓦型太陽電池パネル２の水下側枠材１８が載り、さらに、瓦型太陽電池パネル２の水上側枠材１９の上に水上側の波形瓦１Ｄの垂面部１０が載るようにして葺き重ねられる。   The cross section of the portion where the corrugated roof tile 1D and the roof tile-type solar cell panel 2 meet in the lateral direction and the flow direction conforms to the embodiment shown in FIGS. That is, the right frame material 13 of the tile-type solar cell panel 2 is placed on the underlap portion 11 of the corrugated roof tile 1D, and the tile receiving portion 15 extended to the left frame material 14 of the tile-type solar cell panel 2 is provided. The overlap portion 12 of the corrugated roof tile 1D is placed on the top. As for the flow direction, the panel receiving portion 7 of the corrugated tile 1D installed under the water of the tile-type solar cell panel 2 is struck with a nail or the like on the tile rail 17 disposed on the roof base 16, A water-side frame member 18 of the tile-type solar cell panel 2 is placed thereon, and a vertical surface portion 10 of the water-side corrugated roof tile 1D is placed on the water-side frame member 19 of the tile-type solar cell panel 2. It is piled up.

さらに、この波形瓦１Ｄは、それ自体の水上側縁部と水下側縁部とが平坦面同士で水密的に葺き重ね可能なので、瓦型太陽電池パネル２とは接しない一般部にも葺設することができる。つまり、この１種類の波形瓦１Ｄだけで、瓦型太陽電池パネル２が葺設される部分以外の屋根面略全体（棟際や隅谷などの特殊部位を除く）を葺き上げることが可能である。したがって、瓦型太陽電池パネル２との位置関係に応じて３種類の波形瓦１（１Ａ、１Ｂ、１Ｃ）を使い分ける前述の実施形態に比べて、施工性が各段に向上する。   Further, the corrugated roof tile 1D has its own water-side edge and water-side edge that can be water-tightly stacked between flat surfaces, so that it can also be used for a general portion that is not in contact with the roof tile-type solar cell panel 2. Can be set. That is, it is possible to lift up substantially the entire roof surface (excluding special parts such as the ridges and corners) other than the part where the roof tile-type solar cell panel 2 is installed with only one type of corrugated roof tile 1D. . Therefore, compared with the above-mentioned embodiment which uses three types of corrugated roof tiles 1 (1A, 1B, 1C) according to the positional relationship with the roof tile-type solar cell panel 2, the workability is improved in each stage.

図７は、本発明の実施形態に係る屋根葺き構造の一例を示す瓦割付け図である。また、図８は、この屋根葺き構造において、図６に示した波形瓦１Ｄと併用される他の波形瓦１Ｅの構成例を示す斜視図である。 FIG. 7 is a tile layout diagram showing an example of a roofing structure according to an embodiment of the present invention. FIG. 8 is a perspective view showing a configuration example of another corrugated tile 1E used in combination with the corrugated tile 1D shown in FIG. 6 in this roofing structure.

例示形態にあっては、２種類の波形瓦１（１Ｄ、１Ｅ）と、波形瓦１を横方向に４枚分並べた大きさの平坦な瓦型太陽電池パネル２とが、葺き重ね部（目地）の位置を一段ごとに瓦幅の半分だけずらせて葺設されている。このように、隣り合う屋根葺き材同士の葺き重ね部を互い違いにずらす葺き方を、本明細書においては「千鳥葺き」と呼ぶ。 In the illustrated embodiment, two types of corrugated roof tiles 1 (1D, 1E) and a flat roof tile-type solar cell panel 2 having a size in which four corrugated roof tiles 1 are arranged in the horizontal direction are arranged in a rolled portion ( The position of the joints is shifted by half the tile width for each step . As described above, the method of staggering the overlapping portions of the roofing materials adjacent to each other is referred to as “staggered” in this specification.

千鳥葺きは、一般論としては、筋葺きよりも防水性（排水性）や耐風性の面で有利であるとされている。しかし、前述のように大きい山谷起伏が設けられた左右非対称かつ非合同の断面形状を有する波形瓦１を千鳥葺きしようとすると、当然ながら山谷起伏の流れ方向における連続性が互い違いにずれてしまう。そこで、本実施形態では、そのような形状の波形瓦の千鳥葺きを可能にするために、図６に示した波形瓦１Ｄと、図８に示す波形瓦１Ｅとを併用する。   In general, staggering is said to be more advantageous in terms of waterproofness (drainage) and wind resistance than streaks. However, when trying to stagger the corrugated roof tiles 1 having a left-right asymmetric and non-congruent cross-sectional shape provided with large mountain valley undulations as described above, naturally the continuity in the flow direction of the mountain valley undulations is staggered. Therefore, in the present embodiment, the corrugated roof tile 1D shown in FIG. 6 and the corrugated roof tile 1E shown in FIG.

波形瓦１Ｅは、図６に示した波形瓦１Ｄとは反対に、流れ方向の水下側から水上側に向かって左側に山部４、右側に谷部３が設けられている。本発明においては、この形状の違いを区別するために、図６の波形瓦１Ｄを「谷山タイプ」と呼び、図８の波形瓦１Ｅを「山谷タイプ」と呼ぶ。詳細にいえば、両者の形状は、幅方向の断面を全体的に左右反転させた形状ではなく、幅方向における略中間部で谷部３と山部４との境目を分割し、それらの位置関係を左右入れ替えた形状になっている。   On the opposite side of the corrugated roof tile 1E shown in FIG. 6, the corrugated roof tile 1E is provided with a peak portion 4 on the left side and a trough portion 3 on the right side from the water side in the flow direction toward the water side. In the present invention, in order to distinguish the difference in shape, the corrugated roof tile 1D of FIG. 6 is referred to as a “taniyama type”, and the corrugated roof tile 1E of FIG. More specifically, the shape of both is not a shape in which the cross-section in the width direction is reversed horizontally, but the boundary between the valley portion 3 and the mountain portion 4 is divided at a substantially intermediate portion in the width direction, and their positions The relationship is a left-right interchanged shape.

山谷タイプの波形瓦１Ｅの水上側縁部には、谷山タイプの波形瓦１Ｄと同様に、瓦の幅方向にわたって平坦なパネル受部７が形成されている。パネル受部７は、水上側縁部から流れ方向における所定寸法の範囲内で、水上側縁部と平行に山部４の上部を削ぎ落とすとともに、谷部３の上部を埋めた形状をなしている。パネル受部７の水上側縁部には、一直線状に延びる水返し５が立ち上げられるとともに、その近傍に２ヶ所程度の釘孔６が形成されている。パネル受部７から山部４に連続する面には、その隅に雨水が溜まるのを防ぐため、波形瓦１Ｂと同様の分水嶺（図示せず）が形成されている。また、パネル受部７から谷部３に連続する面９はなだらかに傾斜した弓形状をなしている。 Similar to the valley mountain type corrugated roof tile 1D, a flat panel receiving portion 7 is formed on the water side edge of the mountain valley type corrugated roof tile 1E over the width direction of the roof tile. The panel receiving part 7 has a shape in which the upper part of the mountain part 4 is scraped off in parallel with the water upper edge part and the upper part of the valley part 3 is buried within a predetermined dimension in the flow direction from the water upper edge part. Yes. A water return 5 extending in a straight line is raised at the water-side edge of the panel receiving portion 7, and two nail holes 6 are formed in the vicinity thereof. In order to prevent rainwater from accumulating at the corners, a water divide (not shown) similar to the corrugated roof tile 1B is formed on the surface continuous from the panel receiving part 7 to the mountain part 4. Further, the surface 9 continuing from the panel receiving portion 7 to the valley portion 3 has a gently inclined bow shape.

山谷タイプの波形瓦１Ｅの水下側縁部には、谷山タイプの波形瓦１Ｄと同様に、底辺が一直線状をなす垂面部１０が形成されている。垂面部１０は、山部４の水下側開口面を塞ぐようにして、山部４及び谷部３の水下側縁部から流れ方向と略直交する向きに延設されており、その底辺は、谷部３の最も低い中央部分の裏面とほぼ同じ高さに揃えられている。   Similar to the valley mountain type corrugated roof tile 1D, a vertical surface portion 10 having a straight base is formed on the lower edge of the mountain valley type corrugated roof tile 1E. The vertical surface portion 10 extends from the water-side edge of the mountain portion 4 and the valley portion 3 in a direction substantially orthogonal to the flow direction so as to block the water-side opening surface of the mountain portion 4, and its bottom side Are arranged at almost the same height as the back surface of the lowest central portion of the valley 3.

谷山タイプの波形瓦１Ｄ、及び山谷タイプの波形瓦１Ｅいずれも、瓦全体の実質的な利き幅（働き幅）及び利き足（働き長さ）は共通で、谷部３、山部４それぞれの幅方向における湾曲形状や流れ方向における傾斜形状も共通である。そして、両タイプとも、水下側から水上側に向かって左側の縁部に数センチ幅のアンダーラップ部１１が張り出しており、右側の縁部には、前記アンダーラップ部１１に重なるオーバーラップ部１２が形成されている。   Both the Taniyama type corrugated roof tile 1D and the Yamatani type corrugated roof tile 1E have the same effective width (working width) and dominant foot (working length) of the entire roof tile. The curved shape in the width direction and the inclined shape in the flow direction are also common. In both types, an underlap portion 11 having a width of several centimeters protrudes from the underwater side toward the upper side of the water on the left side edge, and the right side edge portion overlaps the underlap portion 11. 12 is formed.

これら２タイプの波形瓦１（１Ｄ、１Ｅ）は、図７に示すように、屋根面の一段ごとに葺き分けられる。つまり、あるひとつの段には、谷山タイプの波形瓦１Ｄ、山谷タイプの波形瓦１Ｅのうちいずれか一方が、当該段の屋根幅の略全体にわたって同じ向きで葺き重ねられる。そして、その１段上の段には、前記下段とは異なるタイプの波形瓦１が、下段とは葺き重ね位置を瓦幅の略半分ずらして葺き重ねられる。図７においても、山谷の並びを分かりやすくするために、各波形瓦１（１Ｄ、１Ｅ）の山部４の位置に薄網を付している。（図７では山部４を長方形で表しているが、実際の各山部４は水下側に向かってやや拡幅する扇形になる。）どの段においても横方向の葺き重ね順は共通で、例示形態の場合はアンダーラップ部１１及びオーバーラップ部１２の向きに合わせて、各波形瓦１（１Ｄ、１Ｅ）及び瓦型太陽電池パネル２が右側から左側へと葺き重ねられる。 These two types of corrugated roof tiles 1 (1D, 1E) are separated for each step of the roof surface as shown in FIG. In other words, one of the corrugated roof tile 1D of the valley mountain type and the corrugated roof tile 1E of the mountain valley type is stacked on a certain step in the same direction over substantially the entire roof width of the step. Then, on the upper stage, the corrugated roof tiles 1 of a type different from that of the lower stage are stacked with the lower stacking position shifted approximately half the roof tile width. In FIG. 7 as well, a thin net is attached to the position of the peak portion 4 of each corrugated roof tile 1 (1D, 1E) for easy understanding of the arrangement of the valleys. (In FIG. 7, the ridges 4 are represented by rectangles, but each actual ridge 4 has a fan shape that slightly widens toward the bottom of the water.) In any step, the horizontal rolling order is common. In the case of the exemplary embodiment, the corrugated roof tiles 1 (1D, 1E) and the roof tile-type solar cell panel 2 are rolled up from the right side to the left side in accordance with the directions of the underlap portion 11 and the overlap portion 12.

図８は、各段における波形瓦１（１Ｄ、１Ｅ）の横方向の葺き重ね部分の概略断面である。Ｄ−Ｄ断面は谷山タイプの波形瓦１Ｄの葺き重ね部分、Ｅ−Ｅ断面は山谷タイプの波形瓦１Ｅの葺き重ね部分をそれぞれ示している。これらの図から把握されるように、一段ごとに葺き重ね部分の位置が千鳥状にずれていても、屋根面全体としては波形瓦１（１Ｄ、１Ｅ）の山部４及び谷部３が、それぞれ流れ方向に揃うこととなる。 FIG. 8 is a schematic cross-sectional view of the horizontal stacked portion of the corrugated roof tile 1 (1D, 1E) at each stage. The DD cross section shows the stacked portion of the corrugated roof tile 1D of the valley and mountain type, and the EE cross section shows the stacked portion of the corrugated roof tile 1E of the mountain and valley type. As can be grasped from these figures, even if the position of the overlapping portion is staggered for each step , the peak portion 4 and the valley portion 3 of the corrugated roof tile 1 (1D, 1E) as the entire roof surface, Each will be aligned in the flow direction.

波形瓦１（１Ｄ、１Ｅ）と瓦型太陽電池パネル２とが横方向及び流れ方向に取り合う部位の断面は、図５及び図４に示した形態に準じる。すなわち、波形瓦１（１Ｄ、１Ｅ）のアンダーラップ部１１の上に瓦型太陽電池パネル２の右枠材１３が載り、また、瓦型太陽電池パネル２の左枠材１４に延設された瓦受部１５の上に波形瓦１（１Ｄ、１Ｅ）のオーバーラップ部１２が載る。また、流れ方向については、瓦型太陽電池パネル２の水下側に葺設される波形瓦１（１Ｄ、１Ｅ）のパネル受部７の上に瓦型太陽電池パネル２の水下側枠材１８が載り、さらに、瓦型太陽電池パネル２の水上側枠材１９の上に水上側の波形瓦１（１Ｄ、１Ｅ）の垂面部１０が載るようにして葺き重ねられる。こうして、四周が平坦な形状の瓦型太陽電池パネル２と、左右非対称かつ非合同の山谷起伏を有する波形瓦１（１Ｄ、１Ｅ）とが、互いの取り合い部分を水密的に封止した状態で、千鳥葺きされることとなる。   The cross section of the portion where the corrugated roof tiles 1 (1D, 1E) and the roof tile-type solar cell panel 2 meet in the lateral direction and the flow direction conforms to the form shown in FIGS. That is, the right frame member 13 of the tile-shaped solar cell panel 2 is placed on the underlap portion 11 of the corrugated roof tile 1 (1D, 1E), and is extended to the left frame member 14 of the tile-shaped solar cell panel 2. The overlapping part 12 of the corrugated roof tile 1 (1D, 1E) is placed on the roof tile receiving section 15. Moreover, about the flow direction, the underwater side frame material of the tile type solar cell panel 2 on the panel receiving part 7 of the corrugated tile 1 (1D, 1E) installed on the underwater side of the tile type solar cell panel 2. 18 is placed on the water-side frame member 19 of the tile-type solar cell panel 2 so that the vertical surface 10 of the corrugated roof tile 1 (1D, 1E) on the water-side is placed. In this way, the tile-shaped solar cell panel 2 having a flat shape on all four sides and the corrugated roof tile 1 (1D, 1E) having the left-right asymmetrical and uncongruent mountain valley undulations in a state where the mutual contact portions are sealed in a watertight manner. , Will be staggered.

なお、図示は省略するが、Ｊ形瓦その他の左右非対称かつ非合同の山谷形状を有する波形瓦についても、例示したＳ形の波形瓦１（１Ａ、１Ｂ、１Ｃ、１Ｄ、１Ｅ）に準じて、瓦型太陽電池パネル２との一体葺きを実現することができる。波形瓦における谷部の表面は、必ずしも凹状に湾曲していなくてもよい。谷部に相当する片側部分が山部に相当する他側部分よりも明確に低くなっておりさえすれば、例えば谷部が略平坦面や緩い片傾斜面等であってもよい。   In addition, although illustration is abbreviate | omitted, also about the S-shaped corrugated roof tile 1 (1A, 1B, 1C, 1D, 1E) also about the corrugated roof tile which has a J-shaped roof tile and other left-right asymmetrical and non-congruent mountain valley shape, In addition, it is possible to achieve integral firing with the tile-type solar cell panel 2. The surface of the valley in the corrugated roof tile does not necessarily have to be curved in a concave shape. As long as the one side portion corresponding to the valley portion is clearly lower than the other side portion corresponding to the mountain portion, the valley portion may be, for example, a substantially flat surface or a loose one inclined surface.

瓦型太陽電池パネル２の四周を囲む枠材の詳細な断面形状は、波形瓦の形状や寸法に応じて適宜、設計されればよい。波形瓦のアンダーラップ部及びオーバーラップ部の詳細な形状についても、波形瓦自体の本体形状や瓦型太陽電池パネルとの取り合いに応じて適宜、改変可能である。   The detailed cross-sectional shape of the frame material surrounding the four circumferences of the tile-shaped solar cell panel 2 may be appropriately designed according to the shape and dimensions of the corrugated roof tile. The detailed shapes of the underlap portion and the overlap portion of the corrugated roof tile can be modified as appropriate according to the shape of the corrugated roof tile itself and the relationship with the roof tile solar cell panel.
