特開特開平８−１０９７０８号公報Japanese Unexamined Patent Publication No. 8-109708

特許文献１では瓦本体部（はたらき面）は葺いたときの水平面への投影形状が建物の単位寸法の整数分の一（モジュール）にほぼ等しい長さを１辺とする正方形であるから、この瓦本体部を整数個並べて葺くと建物の単位寸法にほぼ合致する。そして、建物の柱は単位寸法に合わせて設けられ、谷や隅棟はこの柱を通過し、水平面への投影形状が壁面から４５°傾斜した傾斜線に沿って設けられるから、瓦を隅棟と隅棟との間に葺く場合には、最初の瓦が瓦本体部であれば最後の瓦が瓦本体部になり、最初の瓦が半瓦本体部であれば最後の瓦が半瓦本体部となる。又、隅棟と谷との間に葺く場合には、谷部分に半瓦本体部の長さだけ開ける必要があるから、最初の瓦が瓦本体部（または半瓦本体部）であれば最後の瓦が半瓦本体部（または瓦本体部）となる。又、谷と谷との間に葺く場合には、両方の谷部分に半瓦本体部の長さだけ開けるから、最初の瓦が瓦本体部であれば最後の瓦が瓦本体部となり、最初の瓦が半瓦本体部であれば最後の瓦が半瓦本体部となる。このように、瓦の割り付けが極めて簡単に出来るという効果を発揮する。 In Patent Document 1, the roof tile main body (working surface) is a square whose one side is a length whose projected shape on the horizontal plane when thatched is approximately equal to an integral fraction (module) of the unit dimension of the building. When an integer number of roof tiles are lined up and thatched, they almost match the unit dimensions of the building. Then, the pillars of the building are provided according to the unit dimensions, the valleys and corner ridges pass through these pillars, and the projected shape on the horizontal plane is provided along the slope line inclined by 45 ° from the wall surface. When roofing between the roof and the corner ridge, if the first tile is the tile body, the last tile will be the tile body, and if the first tile is the half tile body, the last tile will be the half tile. It becomes the main body. Also, when roofing between the corner ridge and the valley, it is necessary to open the valley part by the length of the half-tile body, so if the first tile is the tile body (or half-tile body) The last tile becomes the half-tile body (or tile body). Also, when roofing between valleys, only the length of the half-tile body is opened in both valleys, so if the first tile is the tile body, the last tile will be the tile body. If the first tile is the half-tile body, the last tile is the half-tile body. In this way, the effect of allocating roof tiles is extremely easy.

しかし、特許文献１の屋根材は建物の単位寸法の整数分の一（モジュール）にほぼ等しい長さを１辺とする正方形形状であり、屋根面に割り付けるのに多くの屋根材を配置する必要があり、屋根材の施工に手間が掛かるという課題があった。
寄棟屋根の陸棟際の端部は三又部や陸棟曲がり部などの瓦の納まりがあるが、特許文献１では三又部や陸棟曲がり部と言った部位での専用の瓦の設定は無く、現場で職人が加工する必要があり、この部位での瓦の加工は難しく、現場での施工に手間が掛かるという課題があった。
また、瓦の配置方法においては流れ方向にて一段飛ばしで瓦本体と半瓦とを交互に配置するというルールが必要であり、瓦の割り付けにおいてもルールが煩雑で手間が掛かるという課題があった。
さらに、桟瓦だけでなく両桟瓦、半瓦、両桟半瓦、谷瓦、側方接続部付き谷瓦、廻り隅瓦といった多数の専用瓦の設定が必要であり、多品種小ロット生産方式でないと生産が出来ないことによる生産効率が悪いという課題と、多くの品目を在庫管理しなければならないことによる在庫負担の増大などという課題があった。 However, the roofing material of Patent Document 1 has a square shape having a length approximately equal to an integral fraction (module) of the unit size of the building as one side, and it is necessary to arrange many roofing materials to allocate to the roof surface. There was a problem that it took time and effort to construct the roofing material.
At the end of the hipped roof near the land ridge, there are tiles such as the three-pronged part and the bent part of the land ridge, but in Patent Document 1, the setting of the dedicated roof tile at the three-pronged part and the bent part of the land ridge is There was a problem that it was necessary for a craftsman to process the roof tiles on site, and it was difficult to process the roof tiles at this site, and it took time and effort to construct the roof tiles on site.
In addition, in the method of arranging roof tiles, it is necessary to have a rule that the roof tile body and the half roof tile are arranged alternately by skipping one step in the flow direction, and there is a problem that the rule is complicated and time-consuming in allocating the roof tile. ..
Furthermore, it is necessary to set a large number of dedicated roof tiles such as both roof tiles, half roof tiles, half roof tiles, valley roof tiles, valley roof tiles with side connections, and corner tiles in addition to the roof tiles, which is not a high-mix, small-lot production method. There were problems such as poor production efficiency due to the inability to produce and an increase in inventory burden due to the need to manage the inventory of many items.

本発明によれば、勾配を有する屋根を備える建物の屋根であって、前記屋根は隅棟又は谷を有し、屋根材を桁方向に複数枚並べ、前記屋根材を段方向に複数段並べる屋根において、前記屋根材の働き長さの水平投影寸法が前記建物の設計単位寸法の整数分の一であり、前記屋根材の働き幅寸法が前記働き長さの水平投影寸法の二倍以上の整数倍にすることで、前記屋根材を軒先から陸棟にむかって流れ方向で一段毎に配置する際に、前記屋根材は配置する屋根面の桁方向に対して一方の端部からもう一方の端部方向に前記屋根材の働き長さの水平投影寸法の整数倍をずらして配置し、陸棟部、隅棟部、ケラバ部、壁際部、三又部、陸棟曲がり部、谷部などの屋根端部に規格化した形状の屋根材を配置することで、前記建物の設計単位寸法と連動した屋根材の配置が可能となり、陸棟部、隅棟部、ケラバ部、壁際部、三又部、陸棟曲がり部、谷部など全ての屋根端部において屋根材の配置がルール化出来る。その結果全ての屋根端部において規格化した形状の屋根材を設定し配置することが出来る。
隅棟部及び谷部は、屋根形状を水平投影した際には一方の桁方向を０度に設定した際には必ず４５度に設定されるため、屋根材の配置が一段登るごとに屋根材の働き長さの水平投影寸法分だけ桁方向でずれる。このことを利用し、屋根材の働き幅寸法を働き長さの水平投影寸法の二倍以上の整数倍とし、かつ、屋根材の桁方向での配置の際に屋根材の働き長さの水平投影寸法の整数倍だけ各段でずらす配置ルールにすることで、各段における配置ルールも簡単明瞭で分かりやすく、屋根端部における規格化した形状の屋根材の種類を減らすことが出来る。

By multiplying by an integral multiple, when the roofing material is arranged step by step in the flow direction from the eaves to the land building, the roofing material is arranged from one end to the other with respect to the girder direction of the roof surface to be arranged. Arranged by shifting an integral multiple of the horizontal projection dimension of the working length of the roofing material in the direction of the edge of the roof, such as the land ridge, corner ridge, keraba, wall edge, three-pronged, land ridge bend, valley, etc. By arranging the standardized roof material on the roof edge, it is possible to arrange the roof material in conjunction with the design unit dimensions of the building, and the land ridge, corner ridge, keraba, wall edge, three-pronged part, etc. The arrangement of roofing materials can be ruled at all roof edges such as the bends and valleys of the land building.

本発明の第１の実施の形態における長尺横葺きモジュール屋根材の屋根材配置方法は、勾配を有する屋根を備える建物の屋根であって、前記屋根は隅棟又は谷を有し、屋根材を桁方向に複数枚並べ、前記屋根材を段方向に複数段並べる屋根において、前記屋根材の働き長さの水平投影寸法が前記建物の設計単位寸法の整数分の一であり、前記屋根材の働き幅寸法が前記働き長さの水平投影寸法の二倍以上の整数倍であり、前記屋根材を軒先から陸棟にむかって流れ方向で一段毎に配置する際に、前記屋根材は配置する屋根面の桁方向に対して一方の端部からもう一方の端部方向に前記屋根材の働き長さの水平投影寸法の整数倍をずらして配置し、陸棟部、隅棟部、ケラバ部、壁際部、三又部、陸棟曲がり部、谷部などの全ての屋根端部に規格化した形状の屋根材を配置するものである。本実施の形態によれば、前記建物の設計単位寸法と連動した屋根材の配置が可能となり、陸棟部、隅棟部、ケラバ部、壁際部、三又部、陸棟曲がり部、谷部など全ての屋根端部において屋根材の配置がルール化出来る。その結果全ての屋根端部において規格化した形状の屋根材を設定し配置することが出来る。
隅棟部及び谷部は、屋根形状を水平投影した際には一方の桁方向を０度に設定した際には必ず４５度に設定されるため、屋根材の配置が一段登るごとに屋根材の働き長さの水平投影寸法分だけ桁方向でずれる。このことを利用し、屋根材の働き幅寸法を働き長さの水平投影寸法の二倍以上の整数倍とし、かつ、屋根材の桁方向での配置の際に屋根材の働き長さの水平投影寸法の整数倍だけ各段でずらす配置ルールにすることで、各段における配置ルールも簡単明瞭で分かりやすく、屋根端部における規格化した形状の屋根材の種類を減らすことが出来る。
また、前記屋根材を長尺化することで横方向での施工枚数の減少により施工性を上げることが出来る。 The method for arranging the roofing material of the long horizontal roofing module roofing material in the first embodiment of the present invention is the roof of a building having a sloped roof, and the roof has a corner ridge or a valley and is a roofing material. In a roof in which a plurality of roofing materials are arranged in a girder direction and a plurality of roofing materials are arranged in a step direction, the horizontal projection dimension of the working length of the roofing material is one integral of the design unit dimension of the building, and the roofing material. The working width dimension of is an integral multiple of twice or more the horizontal projection dimension of the working length, and when the roofing material is arranged step by step in the flow direction from the eaves to the land building, the roofing material is arranged. The roofing material is arranged so as to be offset by an integral multiple of the horizontal projection dimension of the working length of the roofing material from one end to the other with respect to the girder direction of the roof surface. A standardized roofing material is placed at all roof edges such as the wall edge, the three-pronged part, the curved part of the land ridge, and the valley part. According to this embodiment, it is possible to arrange the roofing material in conjunction with the design unit dimensions of the building, and all of the land ridge, corner ridge, keraba, wall edge, three-pronged part, land ridge bend, valley, etc. The arrangement of roofing materials can be ruled at the roof edge of the building. As a result, it is possible to set and arrange a roofing material having a standardized shape at all roof edges.
The corner ridge and valley are always set to 45 degrees when one of the girder directions is set to 0 degrees when the roof shape is horizontally projected, so the roof material is set every time the roof material is placed one step up. It shifts in the girder direction by the horizontal projection dimension of the working length of. Taking advantage of this, the working width dimension of the roofing material is set to an integral multiple of twice or more the horizontal projection dimension of the working length, and the working length of the roofing material is horizontal when the roofing material is arranged in the girder direction. By using an arrangement rule that shifts each stage by an integral multiple of the projected dimension, the arrangement rule at each stage is simple, clear, and easy to understand, and the types of roofing materials with a standardized shape at the roof edge can be reduced.
Further, by lengthening the roofing material, the workability can be improved by reducing the number of works to be carried out in the lateral direction.

本発明の第２の実施の形態は、第１の実施の形態による長尺横葺きモジュール屋根材の屋根材配置方法において、前記屋根材を軒先から陸棟にむかって流れ方向で一段毎に配置する際に、前記屋根材は配置する屋根面の桁方向に対して一方の端部からもう一方の端部方向に前記屋根材の働き長さの水平投影寸法をずらして配置するものである。本実施の形態によれば、屋根材の配置が一段登るごとに屋根材の働き長さの水平投影寸法分だけ桁方向でずれるため、屋根材の働き長さの水平投影寸法分だけずらして配置するルールにすることで各段における配置ルールがさらに簡単明瞭で分かりやすくなり、隅棟における一方の隅棟端部における規格化した形状の屋根材が１種類の形状となり、規格化した形状の屋根材の種類をさらに減らすことが出来る。 The second embodiment of the present invention is the method of arranging the roofing material of the long horizontal roofing module roofing material according to the first embodiment, in which the roofing material is arranged step by step in the flow direction from the eaves to the land ridge. At that time, the roofing material is arranged by shifting the horizontal projection dimension of the working length of the roofing material from one end to the other end with respect to the girder direction of the roof surface to be arranged. According to the present embodiment, the arrangement of the roofing material is shifted in the girder direction by the horizontal projection dimension of the working length of the roofing material each time the roofing material is arranged one step, so that the arrangement is shifted by the horizontal projection dimension of the working length of the roofing material. The layout rule at each stage becomes simpler, clearer, and easier to understand, and the standardized roofing material at the end of one corner of the corner ridge becomes one type of roof.

以下本発明の実施例による長尺横葺きモジュール屋根材の屋根材配置方法について説明する。
図１は実施例による寄棟切妻混合屋根での屋根材割り付け図である。
図１は勾配を有する屋根２を備える建物の屋根２であって、屋根２は隅棟３と谷４のある寄棟屋根とケラバ部９ｃを有する切妻屋根とが混在している寄棟切妻混合屋根における屋根材割り付け図である。
図１（ａ）は、寄棟切妻混合屋根における２階屋根の屋根割り付け図を示し、図１（ｂ）は同じ寄棟切妻混合屋根の１階屋根の屋根割り付け図を示す。
建物の設計単位寸法Ｐは尺モジュールであり、設計単位寸法Ｐは９１０mmである。
屋根材１の働き長さの水平投影寸法Ｌｈは、建物の設計単位寸法Ｐの二分の一の４５５mmであり、屋根材１の働き幅寸法Ｗは、働き長さの水平投影寸法Ｌｈの４倍にあたる１８２０mmとする。
先ず、図１（ａ）の下側に記載の台形形状の屋根面における配置方法を説明する。
屋根材１の配置方向は、屋根面の桁方向７に対して右の隅棟部９ｂから左の隅棟部９ｂに向かった方向とする。
隅棟部９ｂには隅棟規格化形状屋根材１０ｂを配置する。
隅棟規格化形状屋根材１０ｂの働き幅寸法は、屋根材１の働き幅寸法Ｗの二分の一にあたる９１０mmとする。
右の隅棟規格化形状屋根材１０ｂと左の隅棟規格化形状屋根材１０ｂの働き幅寸法は同じ９１０mmとする。
右側の隅棟規格化形状屋根材１０ｂを右の隅棟部９ｂに配置し、その左隣に屋根材１を配置し、順次左側の隅棟部９ｂに向かって屋根材１を配置する。
図１（ａ）では、台形面の軒桁寸法は９１００mmであり、設計単位寸法であらわすと１０Ｐとなる。
また軒の出寸法１２が９１０mmであることから、軒先１段目の右の隅棟部９ｂから左の隅棟部９ｂまでの屋根材先端部での寸法は、１２Ｐにあたる１０９２０mmとなる。
屋根材１の働き幅寸法Ｗが２Ｐにあたる１８２０mmであり、隅棟規格化形状屋根材１０ｂがその半分の１Ｐなので、左右の隅棟規格化形状屋根材１０ｂの働き幅寸法を合わせると２Ｐとなる。
屋根材１が５枚で１０Ｐになり、隅棟規格化形状屋根材１０ｂが左右に配置されると２Ｐとなるため、全て合わせると１２Ｐとなり左右対称で綺麗に配置できる。 Hereinafter, a method of arranging the roofing material of the long horizontal roofing module roofing material according to the embodiment of the present invention will be described.
FIG. 1 is a roof material allocation diagram for a hipped gable mixed roof according to an embodiment.
FIG. 1 shows a roof 2 of a building having a sloped roof 2, and the roof 2 is a hipped gable mixed roof in which a hipped roof having a corner building 3 and a valley 4 and a gable roof having a keraba portion 9c are mixed. It is a roofing material allocation diagram in a roof.
FIG. 1 (a) shows a roof allocation diagram of a second-floor roof in a hipped gable mixed roof, and FIG. 1 (b) shows a roof allocation diagram of a first-floor roof of the same hipped gable mixed roof.
The design unit dimension P of the building is a shaku module, and the design unit dimension P is 910 mm.
The horizontal projection dimension Lh of the working length of the roofing material 1 is 455 mm, which is half of the design unit dimension P of the building, and the working width dimension W of the roofing material 1 is four times the horizontal projection dimension Lh of the working length. It is set to 1820 mm, which corresponds to this.
First, a method of arranging the trapezoidal roof surface shown on the lower side of FIG. 1A will be described.
The arrangement direction of the roofing material 1 is the direction from the right corner ridge portion 9b to the left corner ridge portion 9b with respect to the girder direction 7 of the roof surface.
A corner ridge standardized shape roofing material 10b is arranged in the corner ridge portion 9b.
The working width dimension of the corner ridge standardized shape roofing material 10b is 910 mm, which is half of the working width dimension W of the roofing material 1.
The working width dimension of the right corner ridge standardized shape roofing material 10b and the left corner ridge standardized shape roofing material 10b is the same 910 mm.
The right corner ridge standardized shape roofing material 10b is arranged in the right corner ridge portion 9b, the roofing material 1 is arranged on the left side thereof, and the roofing material 1 is sequentially arranged toward the left corner ridge portion 9b.
In FIG. 1A, the eaves girder size of the trapezoidal surface is 9100 mm, which is 10P in terms of the design unit size.
Further, since the eaves protrusion dimension 12 is 910 mm, the dimension at the tip of the roofing material from the right corner ridge 9b to the left corner ridge 9b of the first stage of the eaves is 10920 mm, which corresponds to 12P.
Since the working width dimension W of the roofing material 1 is 1820 mm, which corresponds to 2P, and the corner ridge standardized shape roofing material 10b is 1P, which is half of that, the working width dimension of the left and right corner ridge standardized shape roofing material 10b is 2P. ..
Five roofing materials 1 make 10P, and when the corner ridge standardized shape roofing materials 10b are arranged on the left and right, it becomes 2P. Therefore, when all of them are combined, it becomes 12P, which can be arranged symmetrically and neatly.

屋根材１を１段目に配置したのち、２段目に屋根材１を配置する。
２段目は１段目同様、右側の隅棟部９ｂに１段目と同様の形状の隅棟規格化形状屋根材１０ｂを配置し、その左隣りに屋根材１を配置する。
１段目の屋根材１に対して２段目の屋根材１の配置位置は、桁方向７の左側に屋根材１の働き長さの水平投影寸法Ｌｈである４５５mm分をずらして配置する。
屋根材１を左側の隅棟部９ｂに向かって順次配置し、左側の隅棟部９ｂに１段目と同様の形状の隅棟規格化形状屋根材１０ｂを配置する。
２段目は、１段目と比べ屋根材先端部での桁方向７の寸法が右側で４５５mm、左側で４５５mm短くなるため、左右合わせて９１０mmと１Ｐ分短くなる。
２段目の桁方向７の寸法は、１段目の寸法の１２Ｐから１Ｐ引いた１１Ｐとなり、左右に１Ｐずつの隅棟規格化形状屋根材１０ｂを配置するので、９Ｐのスペースに屋根材１を配置することになる。
屋根材１の働き幅寸法Ｗは２Ｐなので４．５枚分のスペースとなり、屋根材１の働き幅寸法Ｗの０．５枚分の働き幅寸法である９１０mmの調整屋根材１１を左側の隅棟規格化形状屋根材１０ｂの右隣りに１枚配置することで１１Ｐの桁方向７の寸法となり２段目を割り付けることが出来る。 After the roofing material 1 is arranged on the first stage, the roofing material 1 is arranged on the second stage.
In the second stage, as in the first stage, the corner ridge standardized shape roofing material 10b having the same shape as the first stage is arranged in the right corner ridge portion 9b, and the roofing material 1 is arranged on the left side thereof.
The position of the second-stage roofing material 1 with respect to the first-stage roofing material 1 is shifted to the left side in the girder direction 7 by 455 mm, which is the horizontal projection dimension Lh of the working length of the roofing material 1.
The roofing material 1 is sequentially arranged toward the left corner ridge portion 9b, and the corner ridge standardized shape roofing material 10b having the same shape as the first stage is arranged on the left corner ridge portion 9b.
In the second stage, the dimension of the girder direction 7 at the tip of the roofing material is 455 mm shorter on the right side and 455 mm shorter on the left side than the first stage, so that the total length of the left and right sides is 910 mm, which is 1 P shorter.
The dimension of the second stage girder direction 7 is 11P, which is obtained by subtracting 1P from the 1st stage dimension of 12P. Since the corner ridge standardized shape roofing material 10b is arranged on each side of the 1P, the roofing material 1 is placed in the space of 9P. Will be placed.
Since the working width dimension W of the roofing material 1 is 2P, the space is equivalent to 4.5 sheets, and the adjusting roofing material 11 of 910 mm, which is the working width dimension of 0.5 sheets of the working width dimension W of the roofing material 1, is placed in the left corner. By arranging one sheet on the right side of the building standardized shape roofing material 10b, the dimension is 7 in the girder direction of 11P, and the second stage can be assigned.

図１（ａ）の台形面の２段目のように屋根面における桁方向７の寸法調整を行う際には、調整屋根材１１を配置する。
屋根面における桁方向７の寸法は、隅棟部９ｂにおいて片側で屋根材１の働き長さの水平投影寸法Ｌｈの分だけ短くなる。
桁方向７の左右に隅棟３がある場合は、左右で屋根材１の働き長さの水平投影寸法Ｌｈの２倍だけ短くなる。
屋根材１の働き幅寸法Ｗは１８２０mmで屋根材１の働き長さの水平投影寸法Ｌｈの４倍の関係なので、１段ごとに桁方向７で屋根材１の働き長さの水平投影寸法Ｌｈの２倍の寸法が短くなるという事は、調整屋根材１１の働き幅寸法を屋根材１の働き長さの水平投影寸法Ｌｈの２倍に設定することで調整屋根材１１の桁方向７の調整寸法が１段ごとに短くなる桁方向７の寸法と一致する。
調整屋根材１１の働き幅寸法を屋根材１の働き長さの水平投影寸法Ｌｈの２倍の９１０mmに設定することで、屋根材１の働き幅寸法Ｗが１８２０mm、調整屋根材１１の働き幅寸法が９１０mmであることから、屋根材１の働き幅寸法Ｗと調整屋根材１１の働き幅寸法の差分である９１０mmが桁方向７の調整寸法として機能する。 When adjusting the dimensions of the girder direction 7 on the roof surface as in the second step of the trapezoidal surface in FIG. 1A, the adjusting roofing material 11 is arranged.
The dimension of the girder direction 7 on the roof surface is shortened by the horizontal projection dimension Lh of the working length of the roofing material 1 on one side in the corner ridge portion 9b.
When there are corner ridges 3 on the left and right sides of the girder direction 7, the working length of the roofing material 1 is shortened by twice the horizontal projection dimension Lh on the left and right sides.
The working width dimension W of the roofing material 1 is 1820 mm, which is four times the horizontal projection dimension Lh of the working length of the roofing material 1, so the horizontal projection dimension Lh of the working length of the roofing material 1 in the girder direction 7 for each step. The fact that the dimension is twice as short as that of the adjustment roofing material 11 means that the working width dimension of the adjusting roofing material 11 is set to twice the horizontal projection dimension Lh of the working length of the roofing material 1 in the girder direction 7 of the adjusting roofing material 11. The adjustment dimension matches the dimension in the girder direction 7 where the adjustment dimension is shortened step by step.
By setting the working width dimension of the adjusting roofing material 11 to 910 mm, which is twice the horizontal projection dimension Lh of the working length of the roofing material 1, the working width dimension W of the roofing material 1 is 1820 mm, and the working width of the adjusting roofing material 11 Since the dimension is 910 mm, 910 mm, which is the difference between the working width dimension W of the roofing material 1 and the working width dimension of the adjusting roofing material 11, functions as the adjusting dimension in the girder direction 7.

図１（ａ）の左側の屋根面は、桁方向７からみて右側に隅棟部９ｂがあり、左側にケラバ部９ｃがある寄棟切妻混合屋根の屋根面である。
この屋根面では、隅棟３は右側にしかないため、１段目と２段目の桁方向７の寸法差は屋根材１の働き長さの水平投影寸法Ｌｈの１倍となる。
片側にしか隅棟３が存在しない屋根面においては調整屋根材１１の働き幅寸法は、屋根材１の働き長さの水平投影寸法Ｌｈの１倍以上の整数倍となる。
片側に隅棟部９ｂがあり、もう一方にケラバ部９ｃがあり、屋根材１の働き幅寸法Ｗが屋根材１の働き長さの水平投影寸法Ｌｈの４倍である図１（ａ）の屋根面の場合では、調整屋根材１１の働き幅寸法は屋根材１の働き長さの水平投影寸法Ｌｈの１倍と２倍と３倍の３種類が必要となる。
しかし、図１（ａ）では、屋根材１の働き長さの水平投影寸法Ｌｈの１倍の４５５mmと２倍の９１０mmの２種類の働き幅寸法を持つ調整屋根材１１だけで割り付けを行っている。
具体的には、働き幅寸法が３倍の調整屋根材１１が必要な段には１倍の４５５mmと２倍の９１０mmを２枚用いて、複数の調整屋根材１１を組み合わせることで３倍の１３６５mmの寸法調整を行っている。 The roof surface on the left side of FIG. 1A is a roof surface of a hipped gable mixed roof having a corner ridge portion 9b on the right side and a keraba portion 9c on the left side when viewed from the girder direction 7.
On this roof surface, since the corner ridge 3 is only on the right side, the dimensional difference between the first and second girder directions 7 is one times the horizontal projection dimension Lh of the working length of the roofing material 1.
On the roof surface where the corner ridge 3 exists only on one side, the working width dimension of the adjusting roofing material 11 is an integral multiple of one or more times the horizontal projection dimension Lh of the working length of the roofing material 1.
In FIG. 1A, there is a corner ridge portion 9b on one side and a keraba portion 9c on the other side, and the working width dimension W of the roofing material 1 is four times the horizontal projection dimension Lh of the working length of the roofing material 1. In the case of the roof surface, the working width dimension of the adjusting roofing material 11 needs to be three types of one, two, and three times the horizontal projection dimension Lh of the working length of the roofing material 1.
However, in FIG. 1A, allocation is performed only by the adjusting roofing material 11 having two types of working width dimensions, 455 mm, which is once the horizontal projection dimension Lh of the working length of the roofing material 1, and 910 mm, which is twice the working length. There is.
Specifically, two sheets of 1x 455mm and 2x 910mm are used for the steps that require the adjusting roofing material 11 with 3 times the working width dimension, and 3 times by combining a plurality of adjusting roofing materials 11. The dimension of 1365 mm is adjusted.

図１（ａ）の台形面の３段目、４段目における屋根材１と調整屋根材１１の配置は１段目、２段目の配置と同様、３段目は調整屋根材１１が入らず４段目は調整屋根材１１が入る。
３段目は左右の隅棟部９ｂに隅棟規格化形状屋根材１０ｂが配置され、その間のスペースに屋根材１が４枚配置される。
４段目は左右の隅棟部９ｂに隅棟規格化形状屋根材１０ｂが配置され、その間のスペースに屋根材１が３枚配置され、さらに屋根材１の０．５枚分のスペースに調整屋根材１１が１枚配置される。 The arrangement of the roofing material 1 and the adjusting roofing material 11 on the third and fourth stages of the trapezoidal surface of FIG. 1A is the same as the arrangement of the first and second stages, and the adjusting roofing material 11 is inserted in the third stage. The adjustment roofing material 11 is placed in the fourth stage.
In the third stage, the corner ridge standardized shape roofing material 10b is arranged in the left and right corner ridges 9b, and four roofing materials 1 are arranged in the space between them.
In the fourth stage, the corner ridge standardized shape roofing material 10b is arranged in the left and right corner ridges 9b, three roofing materials 1 are arranged in the space between them, and the space is adjusted to 0.5 sheets of the roofing material 1. One roofing material 11 is arranged.

図１（ａ）の屋根２は、２本の陸棟６があり、曲がり部９ｇで直交している。
２本の陸棟６は同じ高さであり、５つの屋根面の流れ長さは全て同じ流れ長さである。
屋根面の流れ長さの水平投影寸法は、陸棟６から軒桁までが５４６０mmの半分の２７３０mmであり、軒桁から軒先５までが９１０mmとなり、軒先５から棟までの流れ長さの水平投影寸法は３６４０mmとなり、建物の設計単位寸法Ｐで言えば４Ｐの寸法となる。
陸棟部９ａの屋根材１の働き長さの水平投影寸法Ｌｈは４５５mmなので、流れ長さの水平投影寸法３６４０mmを１段分の４５５mmで割ることで流れ段数が８段であることを算出することが出来る。 The roof 2 of FIG. 1A has two land ridges 6 and is orthogonal to each other at a bent portion of 9 g.
The two land buildings 6 have the same height, and the flow lengths of the five roof surfaces are all the same.
The horizontal projection dimension of the flow length of the roof surface is 2730 mm, which is half of 5460 mm from the land ridge 6 to the eaves girder, 910 mm from the eaves girder to the eaves tip 5, and the horizontal projection of the flow length from the eaves 5 to the ridge. The dimension is 3640 mm, which is 4P in terms of the design unit dimension P of the building.
Since the horizontal projection dimension Lh of the working length of the roofing material 1 of the land building portion 9a is 455 mm, it is possible to calculate that the number of flow steps is 8 by dividing the horizontal projection dimension 3640 mm of the flow length by 455 mm for one step. You can.

図１（ａ）の台形面の屋根材１と調整屋根材１１の配置は、奇数段である１段目、３段目、５段目、７段目が屋根材１のみで割り付けられ、偶数段である２段目、４段目、６段目が屋根材１と調整屋根材１１により配置される。
陸棟際で最上段の８段目には、屋根材１及び調整屋根材１１を尻側から流れ重なり寸法１３分だけ短くカットされた形状の陸棟規格化形状屋根材１０ａが配置される。 In the arrangement of the roofing material 1 and the adjusting roofing material 11 on the trapezoidal surface of FIG. 1A, the odd-numbered first, third, fifth, and seventh steps are allotted only to the roofing material 1, and are even. The second, fourth, and sixth steps, which are steps, are arranged by the roofing material 1 and the adjusting roofing material 11.
On the 8th stage of the uppermost stage near the land building, a land building standardized shape roofing material 10a having a shape in which the roofing material 1 and the adjusting roofing material 11 flow from the tail side and are cut short by a dimension of 13 minutes is arranged.

図１（ａ）の台形面の右側に位置する三角面は台形面と基本的には同様な屋根材１の配置になる。
ただし、８段目は台形面と異なり陸棟６が存在しないので三又部９ｅに三又規格化形状屋根材１０ｅのみが配置される。 The triangular surface located on the right side of the trapezoidal surface in FIG. 1A has basically the same arrangement of the roofing material 1 as the trapezoidal surface.
However, unlike the trapezoidal surface, the land ridge 6 does not exist in the eighth stage, so only the three-pronged standardized roofing material 10e is arranged in the three-pronged portion 9e.

図１（ａ）の台形面の陸棟６の反対側に位置する平行四辺形面は隅棟３と谷４が平行に位置している。

軒先５から陸棟６に向かって１段登るに際に、桁方向７に対して隅棟部９ｂから谷部９ｆに向かう方向に屋根材１を屋根材１の働き長さの水平投影寸法Ｌｈ分の４５５mmだけずらして配置する。 In the parallelogram surface of the trapezoidal surface of FIG. 1A located on the opposite side of the land ridge 6, the corner ridge 3 and the valley 4 are located in parallel.
The method of arranging the roofing material 1 and the standardized shape roofing material 10 on the parallelogram surface is to arrange the corner ridge standardized shape roofing material 10b similar to the trapezoidal surface on the corner ridge 9b and the valley standardized shape on the valley 9f. The roofing material 10f is arranged, and the roofing material 1 is arranged between them.
When climbing one step from the eaves 5 to the land ridge 6, the roofing material 1 is projected in the direction from the corner ridge 9b to the valley 9f with respect to the girder direction 7, and the horizontal projection dimension Lh of the working length of the roofing material 1. Arrange them with a shift of 455 mm.

５段目以降は１段目から４段目までの配置方法の繰り返しとなる。 The roof surface having the corner ridge 3 and the keraba located on the left side of the trapezoidal surface of FIG. 1 (a) is the corner ridge 9b with respect to the girder direction 7 when climbing one step from the eaves 5 toward the land ridge 6. The roofing material 1 is arranged so as to be offset by 455 mm for the horizontal projection dimension Lh of the working length of the roofing material 1 in the direction from the ridge to the keraba portion 9c.
In the first stage, the corner ridge standardized shape roofing material 10b similar to the trapezoidal surface is arranged in the corner ridge portion 9b on the right side with respect to the girder direction 1, and the roofing material is sequentially placed in the left direction of the corner ridge standardized shape roofing material 10b.

図２は実施例による寄棟屋根の屋根面における屋根材割付図である。
図２は寄棟屋根において軒と隅棟３で三角形形状に構成される三角形状屋根面をベースにして、屋根材１の配置ルールの違いにより屋根材１の配置がどのように変わるかを表した図である。
それぞれの図において次の条件は共通条件としている。
建物の設計単位寸法Ｐは尺モジュールであり、設計単位寸法Ｐは９１０mmである。
屋根材１の働き長さの水平投影寸法Ｌｈは、建物の設計単位寸法Ｐの四分の一の２２７．５mmであり、屋根材１の働き幅寸法Ｗは、働き長さの水平投影寸法Ｌｈの８倍にあたる１８２０mmとする。
屋根２の軒の出寸法１２は４５５mmとする。
流れ方向８の屋根頂点から軒桁までの流れ長さの水平投影寸法は４．５Ｐの４０９５mmであり、屋根頂点から軒先５までの流れ長さの水平投影寸法は軒の出寸法１２の４５５mmを足して１０Ｐの４５５０mmとなる。
桁方向７の軒桁間の寸法は９Ｐの８１９０mmであり、軒先５の桁寸法は軒の出１２の寸法を足すと１０Ｐの９１００mmとなる。 FIG. 2 is a roof material allocation diagram on the roof surface of the hipped roof according to the embodiment.
FIG. 2 shows how the arrangement of the roofing material 1 changes depending on the difference in the arrangement rule of the roofing material 1 based on the triangular roof surface formed by the eaves and the corner ridge 3 in the hipped roof. It is a figure that was made.
In each figure, the following conditions are common conditions.
The design unit dimension P of the building is a shaku module, and the design unit dimension P is 910 mm.
The horizontal projection dimension Lh of the working length of the roofing material 1 is 227.5 mm, which is a quarter of the design unit dimension P of the building, and the working width dimension W of the roofing material 1 is the horizontal projection dimension Lh of the working length. The length is 1820 mm, which is eight times that of.
The protruding dimension 12 of the eaves of the roof 2 is 455 mm.
The horizontal projection dimension of the flow length from the roof apex to the eaves girder in the flow direction 8 is 4095 mm of 4.5P, and the horizontal projection dimension of the flow length from the roof apex to the eaves tip 5 is 455 mm of the eaves protrusion dimension 12. Add up to 4550mm of 10P.
The dimension between the eaves girders in the girder direction 7 is 8190 mm of 9P, and the girder dimension of the eaves tip 5 is 9100 mm of 10P when the dimensions of the eaves protrusion 12 are added.

図２（ａ）の配置方法について説明する。
図２（ａ）は屋根端部９に、軒桁方向７に対して右側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、左側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを４種類配置し、三又部９ｅに三又規格化形状屋根材１０ｅを４種類配置した配置方法である。
軒先５から１段毎登るに際に、桁方向７に対して右側の隅棟部９ｂから左側の隅棟部９ｂに向かう方向で屋根材１を屋根材１の働き長さの水平投影寸法Ｌｈ分の２２７．５mmだけずらして配置する。
この配置方法は、調整屋根材１１の配置が無いため配置ルールが分かりやすいというメリットがある。
しかし、屋根端部９の規格化形状屋根材１０は９種類と多くなってしまう事がデメリットとしてある。 The arrangement method of FIG. 2A will be described.
In FIG. 2A, one type of corner ridge standardized shape roofing material 10b is arranged on the roof edge 9 on the right corner ridge 9b with respect to the eaves girder direction 7, and the corner ridge standard is placed on the left corner ridge 9b. This is an arrangement method in which four types of shaped roofing materials 10b are arranged and four types of three-pronged standardized roofing materials 10e are arranged on the three-pronged portion 9e.
When climbing step by step from the eaves 5, the roofing material 1 is projected in the direction from the right corner ridge 9b to the left corner ridge 9b with respect to the girder direction 7, and the horizontal projection dimension Lh of the working length of the roofing material 1. Arrange them with a shift of 227.5 mm.
This arrangement method has an advantage that the arrangement rule is easy to understand because the adjustment roofing material 11 is not arranged.
However, there is a demerit that the standardized shape roofing material 10 of the roof end portion 9 is increased to 9 types.

図２（ｂ）の配置方法について説明する。
図２（ｂ）は屋根端部９に、軒桁方向７に対して右側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、左側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを２種類配置し、三又部９ｅに三又規格化形状屋根材１０ｅを４種類配置した配置方法である。
また、桁方向７の寸法調整を行うために、屋根材１の働き長さの水平投影寸法Ｌｈの４倍となる９１０mmの働き幅寸法を有した調整屋根材１１を１種類配置している。
軒先５から１段毎登るに際に、桁方向７に対して右側の隅棟部９ｂから左側の隅棟部９ｂに向かう方向で屋根材１を屋根材１の働き長さの水平投影寸法Ｌｈ分の２２７．５mmだけずらして配置する。
この配置方法は、屋根端部９の規格化形状屋根材１０の種類を７種類に減らすことが出来るのがメリットである。
調整屋根材１１を入れて桁方向７の寸法調整をすることで配置ルールが複雑になることと、調整屋根材１１を１種類追加するためそれほど種類が減らないことがデメリットとしてある。 The arrangement method of FIG. 2B will be described.
In FIG. 2B, one type of corner ridge standardized shape roofing material 10b is arranged on the roof edge 9 on the right corner ridge 9b with respect to the eaves girder direction 7, and the corner ridge standard is placed on the left corner ridge 9b. This is an arrangement method in which two types of the shaped roofing material 10b are arranged and four types of the three-pronged standardized roofing material 10e are arranged in the three-pronged portion 9e.
Further, in order to adjust the dimensions in the girder direction 7, one type of adjusting roofing material 11 having a working width dimension of 910 mm, which is four times the horizontal projection dimension Lh of the working length of the roofing material 1, is arranged.
When climbing step by step from the eaves 5, the roofing material 1 is projected in the direction from the right corner ridge 9b to the left corner ridge 9b with respect to the girder direction 7, and the horizontal projection dimension Lh of the working length of the roofing material 1. Arrange them with a shift of 227.5 mm.
This arrangement method has an advantage that the types of the standardized shape roofing material 10 of the roof end portion 9 can be reduced to 7 types.
Disadvantages are that the arrangement rule becomes complicated by inserting the adjusting roofing material 11 and adjusting the dimensions in the girder direction 7, and that the number of types does not decrease so much because one type of adjusting roofing material 11 is added.

図２（ｃ）の配置方法について説明する。
図２（ｃ）は屋根端部９に、軒桁方向７に対して右側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、左側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、三又部９ｅに三又規格化形状屋根材１０ｅを３種類配置した配置方法である。
また、桁方向７の寸法調整を行うために、屋根材１の働き長さの水平投影寸法Ｌｈの２倍の４５５mm、４倍の９１０mm、６倍の１３６５ｍｍの働き幅寸法を有した複数の調整屋根材１１を３種類配置している。
軒先５から１段毎登るに際に、桁方向７に対して右側の隅棟部９ｂから左側の隅棟部９ｂに向かう方向で屋根材１を屋根材１の働き長さの水平投影寸法Ｌｈ分の２２７．５mmだけずらして配置する。
隅棟規格化形状屋根材１０ｂの働き幅寸法は、屋根材１の働き幅寸法Ｗの二分の一にあたる９１０mmとする。
右の隅棟規格化形状屋根材１０ｂと左の隅棟規格化形状屋根材１０ｂの働き幅寸法は同じ９１０mmとする。
この配置方法は、屋根端部９の規格化形状屋根材１０の種類を５種類に減らすことが出来るのと、隅棟部９ｂの隅棟規格化形状屋根材１０ｂが１種類になるため隅棟部における配置ルールが分かりやすくなるというのがメリットである。
また、左右の隅棟規格化形状屋根材１０ｂが屋根材１の働き幅寸法Ｗの二分の一にあたる９１０mmなので屋根材１から２左右の隅棟規格化形状屋根材１０ｂをプレカットすることが出来るので、隅棟規格化形状屋根材１０ｂの生産効率が高いというメリットもある。
しかし、調整屋根材１１が３種類配置されることで配置ルールが複雑になることと、調整屋根材１１を３種類追加するためそれほど種類が減らないことがデメリットとしてある。 The arrangement method of FIG. 2C will be described.
In FIG. 2C, one type of corner ridge standardized shape roofing material 10b is arranged on the roof edge 9 on the right corner ridge 9b with respect to the eaves girder direction 7, and the corner ridge standard is placed on the left corner ridge 9b. This is an arrangement method in which one type of the modified shape roofing material 10b is arranged and three types of the three-pronged standardized roofing material 10e are arranged in the three-pronged portion 9e.
Further, in order to adjust the dimensions in the girder direction 7, a plurality of adjustments having a working width dimension of 455 mm, which is twice the horizontal projection dimension Lh of the working length of the roofing material 1, 910 mm, which is four times, and 1365 mm, which is six times. Three types of roofing materials 11 are arranged.
When climbing step by step from the eaves 5, the roofing material 1 is projected in the direction from the right corner ridge 9b to the left corner ridge 9b with respect to the girder direction 7, and the horizontal projection dimension Lh of the working length of the roofing material 1. Arrange them with a shift of 227.5 mm.
The working width dimension of the corner ridge standardized shape roofing material 10b is 910 mm, which is half of the working width dimension W of the roofing material 1.
The working width dimension of the right corner ridge standardized shape roofing material 10b and the left corner ridge standardized shape roofing material 10b is the same 910 mm.
This arrangement method can reduce the types of the standardized shape roofing material 10 of the roof end portion 9 to five types, and the corner ridge standardized shape roofing material 10b of the corner ridge portion 9b becomes one type. The advantage is that the placement rules in the department are easy to understand.
Further, since the left and right corner ridge standardized shape roofing materials 10b are 910 mm, which is half of the working width dimension W of the roofing material 1, the left and right corner ridge standardized shape roofing materials 10b can be precut. There is also an advantage that the production efficiency of the corner ridge standardized shape roofing material 10b is high.
However, there are disadvantages that the arrangement rule becomes complicated by arranging three types of the adjusting roofing material 11 and that the number of types does not decrease so much because three types of the adjusting roofing material 11 are added.

図２（ｄ）の配置方法について説明する。
図２（ｄ）は屋根端部９に、軒桁方向７に対して右側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、左側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、三又部９ｅに三又規格化形状屋根材１０ｅを３種類配置した配置方法である。
また、桁方向７の寸法調整を行うために、屋根材１の働き長さの水平投影寸法Ｌｈの２倍の４５５mm、４倍の９１０mmの働き幅寸法を有した複数の調整屋根材１１を２種類配置している。
軒先５から１段毎登るに際に、桁方向７に対して右側の隅棟部９ｂから左側の隅棟部９ｂに向かう方向で屋根材１を屋根材１の働き長さの水平投影寸法Ｌｈ分の２２７．５mmだけずらして配置する。
隅棟規格化形状屋根材１０ｂの働き幅寸法は、屋根材１の働き幅寸法Ｗの二分の一にあたる９１０mmとする。
右の隅棟規格化形状屋根材１０ｂと左の隅棟規格化形状屋根材１０ｂの働き幅寸法は同じ９１０mmとする。
２種類の調整屋根材を組み合わせることで３種類の桁方向７における寸法調整が出来る。
この配置方法は、屋根端部９の規格化形状屋根材１０の種類を５種類に減らすことが出来るのと、調整屋根材１１を２種類に減らすこと、隅棟部９ｂの隅棟規格化形状屋根材１０ｂが１種類になるため隅棟部における配置ルールが分かりやすくなるというのがメリットである。
また、左右の隅棟規格化形状屋根材１０ｂが屋根材１の働き幅寸法Ｗの二分の一にあたる９１０mmなので屋根材１から２左右の隅棟規格化形状屋根材１０ｂをプレカットすることが出来るので、隅棟規格化形状屋根材１０ｂの生産効率が高いというメリットもある。
しかし、調整屋根材１１が２種類配置され、かつ調整屋根材１１を組み合わせることで３種類の寸法調整が出来ることで配置ルールが複雑になることがデメリットとしてある。 The arrangement method of FIG. 2D will be described.
In FIG. 2D, one type of corner ridge standardized shape roofing material 10b is arranged on the roof edge 9 on the right corner ridge 9b with respect to the eaves girder direction 7, and the corner ridge standard is placed on the left corner ridge 9b. This is an arrangement method in which one type of the modified shape roofing material 10b is arranged and three types of the three-pronged standardized roofing material 10e are arranged in the three-pronged portion 9e.
Further, in order to adjust the dimensions in the girder direction 7, a plurality of adjusting roofing materials 11 having a working width dimension of 455 mm, which is twice the horizontal projection dimension Lh of the working length of the roofing material 1, and 910 mm, which is four times, are used. The types are arranged.
When climbing step by step from the eaves 5, the roofing material 1 is projected in the direction from the right corner ridge 9b to the left corner ridge 9b with respect to the girder direction 7, and the horizontal projection dimension Lh of the working length of the roofing material 1. Arrange them with a shift of 227.5 mm.
The working width dimension of the corner ridge standardized shape roofing material 10b is 910 mm, which is half of the working width dimension W of the roofing material 1.
The working width dimension of the right corner ridge standardized shape roofing material 10b and the left corner ridge standardized shape roofing material 10b is the same 910 mm.
By combining two types of adjustment roofing materials, it is possible to adjust the dimensions in three types of girder directions 7.
This arrangement method can reduce the types of the standardized shape roof material 10 of the roof end portion 9 to 5 types, reduce the adjustment roof material 11 to 2 types, and standardize the corner ridge portion 9b. Since there is only one type of roofing material 10b, there is an advantage that the arrangement rules in the corner ridges can be easily understood.
Further, since the left and right corner ridge standardized shape roofing materials 10b are 910 mm, which is half of the working width dimension W of the roofing material 1, the left and right corner ridge standardized shape roofing materials 10b can be precut. There is also an advantage that the production efficiency of the corner ridge standardized shape roofing material 10b is high.
However, there is a demerit that two types of adjusting roofing materials 11 are arranged and three types of dimensional adjustments can be made by combining the adjusting roofing materials 11, which complicates the arrangement rules.

図３は実施例による寄棟屋根での軒の出変化による屋根材割付図である。
図３は寄棟屋根において軒と隅棟３で三角形形状に構成される三角形状屋根面をベースにして、屋根材１の働き長さの水平投影寸法Ｌｈが建物の設計単位寸法Ｐの奇数分の一の場合における屋根材１の軒の出変化による配置方法の違いを表した図である。

屋根材１の働き長さの水平投影寸法Ｌｈが建物の設計単位寸法Ｐの三分の一なので奇数分の一の場合に該当する。
流れ方向８の屋根頂点から軒桁までの流れ長さの水平投影寸法は４Ｐの３６４０mmである。
桁方向７の軒桁間の寸法は８Ｐの７２８０mmである。 FIG. 3 is a roofing material allocation diagram due to changes in the appearance of the eaves on the hipped roof according to the embodiment.
FIG. 3 shows that the horizontal projection dimension Lh of the working length of the roofing material 1 is an odd portion of the design unit dimension P of the building based on the triangular roof surface formed by the eaves and the corner ridge 3 in the hipped roof. It is a figure which showed the difference of the arrangement method by the eaves change of the roofing material 1 in the case of 1.
In each figure, the following conditions are common conditions.
The design unit dimension P of the building is a shaku module, and the design unit dimension P is 910 mm.
The horizontal projection dimension Lh of the working length of the roofing material 1 is 303.33 mm, which is one-third of the design unit dimension P of the building, and the working width dimension W of the roofing material 1 is the horizontal projection dimension Lh of the working length. It is set to 1213.32 mm, which is four times the size of.
Since the horizontal projection dimension Lh of the working length of the roofing material 1 is one-third of the design unit dimension P of the building, it corresponds to the case of an odd-numbered one.
The horizontal projection dimension of the flow length from the roof apex to the eaves girder in the flow direction 8 is 3640 mm of 4P.
The dimension between the eaves girders in the girder direction 7 is 7280 mm of 8P.

図３（ａ）の配置方法について説明する。
屋根２の軒の出寸法１２は、９１０mmである。
軒の出寸法１２の９１０mmは屋根材１の働き長さの水平投影寸法Ｌｈの二分の一にあたる１５１．６７mmの６倍となる。
流れ方向８の屋根頂点から軒桁までの流れ長さの水平投影寸法は４Ｐの３６４０mmなので屋根頂点から軒先５までの流れ長さの水平投影寸法は軒の出寸法１２の９１０mmを足して５Ｐの４５５０mmとなる。
桁方向７の軒桁間の寸法は８Ｐの７２８０mmであり、軒先５の桁寸法は軒の出１２の寸法を足して１０Ｐの９１００mmとなる。
図３（ａ）は屋根端部９に、軒桁方向７に対して右側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、左側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを１種類配置し、三又部９ｅに三又規格化形状屋根材１０ｅを１種類配置した配置方法である。
軒先５から１段毎登るに際に、桁方向７に対して右側の隅棟部９ｂから左側の隅棟部９ｂに向かう方向で屋根材１を屋根材１の働き長さの水平投影寸法Ｌｈ分の３０３．３３mmだけずらして配置する。
隅棟規格化形状屋根材１０ｂの働き幅寸法は、屋根材１の働き幅寸法Ｗの二分の一にあたる６０６．６７mmとする。
右の隅棟規格化形状屋根材１０ｂと左の隅棟規格化形状屋根材１０ｂの働き幅寸法は同じ６０６．６７mmとする。
桁方向７の寸法調整に調整屋根材１１を用いる。調整屋根材１１の働き幅寸法は、屋根材１の働き長さの水平投影寸法Ｌｈの２倍にあたる６０６．６７とする。
１段目の右側の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを配置し、左隣りから順次屋根材１を配置する。
軒先５の桁寸法は１０Ｐの９１００mmを屋根材１の働き幅寸法Ｗが１２１３．３２mmで割ると７．５枚となる。
左右の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを配置し、屋根材１を６枚配置すると屋根材１の０．５枚分のスペースが空き、そのスペースに働き幅寸法６０６．６７ｍｍの調整屋根材１１を配置する。
２段目は右側の隅棟部９bで屋根材１の働き長さの水平投影寸法Ｌｈ分の３０３．３３mm、左側の隅棟部９ｂで屋根材１の働き長さの水平投影寸法Ｌｈ分の３０３．３３mmが桁方向７で短くなる。つまり、１段ごとに桁方向７の寸法が６０６．６７mmだけ短くなる。
６０６．６７mmは屋根材１の働き幅寸法Ｗの０．５枚分の寸法になる。
２段目の桁方向７の寸法は、１段目の桁方向７の寸法の７．５枚から０．５枚短くなるので屋根材１の６枚分の寸法となる。
そのため、２段目は左右の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを配置し、屋根材１を５枚配置となる。
３段目は桁方向７の寸法が２段目より０．５枚短い６．５枚となるので、１段目と同様の左右の隅棟部９ｂに隅棟規格化形状屋根材１０ｂを配置し、屋根材１を配置し、働き幅寸法６０６．６７ｍｍの調整屋根材１１を配置する。
３段目、４段目以降は、１段目、２段目と同様の配置を繰り返すことになる。
１３段目は、隅棟規格化形状屋根材１０ｂと調整屋根材１１のみの配置となり、１４段目は隅棟規格化形状屋根材１０ｂのみの配置となり、１５段目は三又規格化形状屋根材１０ｅの配置となる。
１５段目の頂点部の三又規格化形状屋根材１０ｅは、働き長さの水平投影寸法が３０３．３３mmとなる。 The arrangement method of FIG. 3A will be described.
The protruding dimension 12 of the eaves of the roof 2 is 910 mm.
The eaves protrusion dimension 12 of 910 mm is six times as large as 151.67 mm, which is half of the horizontal projection dimension Lh of the working length of the roofing material 1.
Since the horizontal projection dimension of the flow length from the roof apex to the eaves girder in the flow direction 8 is 3640 mm of 4P, the horizontal projection dimension of the flow length from the roof apex to the eaves tip 5 is 5P by adding 910 mm of the eaves protrusion dimension 12. It becomes 4550 mm.
The dimension between the eaves girders in the girder direction 7 is 7280 mm of 8P, and the girder dimension of the eaves tip 5 is 9100 mm of 10P by adding the dimensions of the eaves protrusion 12.
In FIG. 3A, one type of corner ridge standardized shape roofing material 10b is arranged on the roof edge 9 on the right corner ridge 9b with respect to the eaves girder direction 7, and the corner ridge standard is placed on the left corner ridge 9b. This is an arrangement method in which one type of the modified shape roofing material 10b is arranged and one type of the three-pronged standardized roofing material 10e is arranged in the three-pronged portion 9e.
When climbing step by step from the eaves 5, the roofing material 1 is projected in the direction from the right corner ridge 9b to the left corner ridge 9b with respect to the girder direction 7, and the horizontal projection dimension Lh of the working length of the roofing material 1. Arrange them with a shift of 303.33 mm.
The working width dimension of the corner ridge standardized shape roofing material 10b is 606.67 mm, which is half of the working width dimension W of the roofing material 1.
The working width dimension of the right corner ridge standardized shape roofing material 10b and the left corner ridge standardized shape roofing material 10b is the same 606.67 mm.
The adjusting roofing material 11 is used for adjusting the dimensions in the girder direction 7. The working width dimension of the adjusting roofing material 11 is 606.67, which is twice the horizontal projection dimension Lh of the working length of the roofing material 1.
The corner ridge standardized shape roofing material 10b is arranged in the corner ridge portion 9b on the right side of the first stage, and the roofing material 1 is arranged sequentially from the left side.
The girder size of the eaves 5 is 7.5 pieces when 9100 mm of 10P is divided by the working width size W of the roofing material 1 by 1213.32 mm.
When the corner ridge standardized shape roofing material 10b is placed on the left and right corner ridges 9b and six roofing materials 1 are placed, a space equivalent to 0.5 of the roofing material 1 is vacant, and the working width dimension is 606.67 mm in that space. The adjustment roofing material 11 of the above is arranged.
In the second stage, the right corner ridge 9b has a horizontal projection dimension of 303.33 mm for the working length of the roofing material 1, and the left corner ridge 9b has a horizontal projection dimension of the working length of the roofing material 1 for Lh. 303.33 mm becomes shorter in the girder direction 7. That is, the dimension of the girder direction 7 is shortened by 606.67 mm for each step.
606.67 mm is the size of 0.5 sheets of the working width dimension W of the roofing material 1.
The dimension of the second stage girder direction 7 is 0.5 sheets shorter than the dimension of the first stage girder direction 7 by 0.5 sheets, so that it is the size of 6 sheets of the roofing material 1.
Therefore, in the second stage, the corner ridge standardized shape roofing material 10b is arranged on the left and right corner ridges 9b, and five roofing materials 1 are arranged.
Since the dimension of the girder direction 7 in the third stage is 6.5 sheets, which is 0.5 sheets shorter than that in the second stage, the corner ridge standardized shape roofing material 10b is placed in the left and right corner ridges 9b similar to the first stage. Then, the roofing material 1 is arranged, and the adjusting roofing material 11 having a working width dimension of 606.67 mm is arranged.

The roofing materials 11 are arranged one by one.
Since the dimension of the girder direction 7 in the third stage is 5.75 sheets, which is 0.5 sheets shorter than that in the second stage, the corner ridge standardized shape roofing material 10b is placed in the left and right corner ridges 9b similar to the first stage. Then, the roofing material 1 is arranged, and the adjusting roofing material 11 having a working width dimension of 910 mm is arranged.

実施例では１．５mmの厚みにしているが、例えば０．６mmの２重折りで同様の形状に形成しても良い。
実施例では４寸勾配対応の屋根材１の働き長さ寸法Ｌとしているが、尻側係合部１９の長さを変えることで屋根材１の働き長さ寸法Ｌを変え、他の勾配にも対応することが出来る。
また、尻側係合部１９の長さを変えずに尻側係合部１９の屋根材１への固定位置を変更することでも屋根材１の働き長さ寸法Ｌを変えることが出来る。
３寸勾配の勾配伸び率は１．０４４なので、３寸勾配の屋根で屋根材１の働き長さの水平投影寸法Ｌｈが４５５mmになる屋根材１の働き長さ寸法Ｌを求めたいときには、４５５mmに対応する屋根勾配の勾配伸び率である１．０４４を掛けることで屋根材１の働き長さ寸法Ｌが４７５mmとして求められる。

Can also be supported.
Further, the working length dimension L of the roofing material 1 can be changed by changing the fixing position of the buttock-side engaging portion 19 to the roofing material 1 without changing the length of the tail-side engaging portion 19.
Since the gradient elongation rate of the 3-inch gradient is 1.044, when the horizontal projection dimension Lh of the working length of the roofing material 1 is 455 mm on the roof with a 3-dimensional gradient, the working length dimension L of the roofing material 1 is 455 mm. By multiplying 1.044, which is the slope elongation rate of the roof slope corresponding to, the working length dimension L of the roofing material 1 is obtained as 475 mm.
By extending the dimension of the tail side engaging portion 19 by 15 mm and setting the working length dimension L of the roofing material 1 to 475 mm, the roofing material 1 corresponding to a 3 inch gradient can be obtained.
Further, the working length dimension L of the roofing material 1 can be set to 475 mm by fixing the tail side engaging portion 19 by shifting it to the head side by 15 mm.
By making the butt-side engaging portion 19 a separate part, it is possible to handle the gradient without changing the main body shape of the roofing material 1.
In the embodiment, the tail side engaging portion 19 is used as a separate part to increase the ability to cope with the gradient, but when a large amount of the same gradient is used, it may be formed integrally with the main body.

屋根材１の働き長さの水平投影寸法Ｌｈは、建物の設計単位寸法Ｐの二分の一の４５５mmであり、屋根材１の働き幅寸法Ｗは、働き長さの水平投影寸法Ｌｈの４倍にあたる１８２０mmである。
屋根２の屋根勾配は４寸勾配、軒の出寸法１２は９７１mmである。
軒桁から陸棟までの流れ長さの水平投影寸法は３Ｐの２７３０mmであり、軒先５から陸棟６までの流れ長さの水平投影寸法は軒の出寸法１２の９７１mmを足して３７０１mmとなる。
屋根材１の働き長さ寸法Ｌは４９０mmであり、屋根材１の働き長さの水平投影寸法Ｌｈは４５５mmとなる。
屋根材１の施工は、下段の尻側係合部１９に上段の頭側係合部１８を係合させ、尻側係合部１９の箇所で留め付け材２２により野地板に留め付ける。
陸棟際の最上段の屋根材１に関しては、尻部係合部１９が不要なので尻端部折り返し２０付近に留め付け材２２で野地板に留め付ける。
屋根材１の働き長さの水平投影寸法Ｌｈが二分の一と偶数分の一なので建物の軒の出寸法１２は、屋根材１の働き長さの水平投影寸法Ｌｈの整数倍に所定の寸法を加えた寸法となる。
実施例では、屋根材１の働き長さの水平投影寸法Ｌｈは４５５mmの２倍に所定の寸法である６１mmを足して軒の出寸法１２を９７１mmとしている。
図１から図３までの割り付け図は軒の出寸法１２については所定寸法を０とした実施例として記載しているが、図５のように陸棟部９aの陸棟規格化形状屋根材１０ａを屋根材１のまま加工せずに割り付ける場合は、軒の出寸法１２に所定寸法をプラスすることが必要になる。
所定寸法は、屋根材１の流れ重なり寸法１４の水平投影寸法と屋根材１の尻端部から陸棟６の棟芯までの端部隙間寸法１５を合わせた寸法となる。
実施例では、屋根材１の流れ重なり寸法１４の水平投影寸法が５０mm、屋根材１の尻端部から陸棟６の棟芯までの端部隙間寸法１５が１１mmなので合わせた６１mmが所定寸法となる。
軒の出寸法１２に所定寸法として屋根材１の流れ重なり寸法１４の水平投影寸法と屋根材１の尻端部から陸棟６の棟芯までの端部隙間寸法１５を足すことで陸棟部９aに配置する屋根材１を加工しなくても納めることが出来る。
しかし、軒先方向に所定寸法分だけ軒の出寸法１２が伸びるという事は、屋根材１の先端位置が軒先方向に所定寸法分伸びるという事であり、それに伴い隅棟３と屋根材１との距離が桁方向７で所定寸法分だけ広くなるということである。
そのため、所定寸法を設定した場合には、隅棟規格化形状屋根材１０ｂの働き寸法及び隅棟規格化形状屋根材１０ｂと隅棟６との端部隙間寸法１５を所定寸法分考慮した設定にすることが必要となる。 FIG. 5 is a flow direction allocation diagram when the roofing material near the land building according to the embodiment is genuine.

As for the roofing material 1 on the uppermost stage near the land building, since the buttock engaging portion 19 is unnecessary, the roofing material 22 is fastened to the field board near the butt end folded back 20.
Since the horizontal projection dimension Lh of the working length of the roofing material 1 is one half and one even number, the protruding dimension 12 of the eaves of the building is a predetermined dimension that is an integral multiple of the horizontal projection dimension Lh of the working length of the roofing material 1. Is added.
In the embodiment, the horizontal projection dimension Lh of the working length of the roofing material 1 is twice the 455 mm and 61 mm, which is a predetermined dimension, is added to set the eaves protrusion dimension 12 to 971 mm.
In the allocation diagram of FIGS. 1 to 3, the eaves protrusion dimension 12 is described as an example in which the predetermined dimension is set to 0, but as shown in FIG. 5, the land building standardized shape roofing material 10a of the land building portion 9a is used as a roof. When allocating the material 1 as it is without processing, it is necessary to add a predetermined dimension to the eaves protrusion dimension 12.
The predetermined dimension is a combination of the horizontal projection dimension of the flow overlapping dimension 14 of the roofing material 1 and the end gap dimension 15 from the tail end portion of the roofing material 1 to the ridge core of the land ridge 6.
In the embodiment, the horizontal projection dimension of the flow overlapping dimension 14 of the roofing material 1 is 50 mm, and the end gap dimension 15 from the tail end portion of the roofing material 1 to the ridge core of the land ridge 6 is 11 mm, so a total of 61 mm is the predetermined dimension. Become.
By adding the horizontal projection dimension of the flow overlap dimension 14 of the roofing material 1 and the end gap dimension 15 from the tail end portion of the roofing material 1 to the ridge core of the land ridge 6 as a predetermined dimension to the eaves protrusion dimension 12, the land ridge portion 9a is formed. It can be stored without processing the roofing material 1 to be arranged.
However, the fact that the eaves protruding dimension 12 extends in the eaves direction by a predetermined dimension means that the tip position of the roofing material 1 extends in the eaves direction by a predetermined dimension, and accordingly, the corner ridge 3 and the roofing material 1 extend. This means that the distance increases by a predetermined dimension in the girder direction 7.
Therefore, when the predetermined dimensions are set, the working dimensions of the corner ridge standardized shape roofing material 10b and the end gap dimension 15 between the corner ridge standardized shape roofing material 10b and the corner ridge 6 are set in consideration of the predetermined dimensions. It is necessary to do.
