Description

本発明は、屋根上に葺かれる屋根瓦および太陽光発電システムに関する。   The present invention relates to a roof tile and a photovoltaic power generation system to be laid on a roof.

瓦葺きの屋根では、屋根下地上に複数の屋根瓦が葺かれている。特許文献１には、太陽光発電システム機器等の設備機器を、瓦葺きの屋根に設置するための支持金具が開示されている。支持金具は、屋根下地に固定される底面部と、底面部から延びて隣接する屋根瓦の隙間から露出する延出部とを有する。設備機器は、屋根瓦の隙間から露出した延出部に固定される。   In a tiled roof, a plurality of roof tiles are laid on the roof foundation. Patent Literature 1 discloses a support metal fitting for installing equipment such as a photovoltaic power generation system device on a roof of a tiled roof. The support metal fitting has a bottom surface portion fixed to the roof base and an extending portion that extends from the bottom surface portion and is exposed from a gap between adjacent roof tiles. The equipment is fixed to the extended portion exposed from the gap between the roof tiles.

特開２０１３−６８０４７号公報JP 2013-68047 A

しかしながら、上記従来の技術によれば、設備機器の重量によって支持金具の腕部が変形した場合、屋根瓦に荷重が加わって屋根瓦が破損してしまうおそれがあった。設備機器の荷重を分散して腕部の変形を抑えるために、多くの支持金具を使用する必要が生じる場合があった。使用する支持金具が増えることで、設備機器の設置作業に必要な工数の増加、および使用材料の増加によって設置コストの増大を招いてしまう。   However, according to the above conventional technique, when the arm portion of the support fitting is deformed due to the weight of the equipment, there is a possibility that the roof tile is damaged due to the load applied to the roof tile. In order to disperse the load of the equipment and suppress the deformation of the arm portion, it may be necessary to use many support fittings. The increase in the number of support fittings to be used leads to an increase in installation costs due to an increase in man-hours required for installation work of equipment and an increase in materials used.

本発明は、上記に鑑みてなされたものであって、屋根上に設置された設備機器からの荷重による破損を抑えることで、設備機器の設置に必要な支持金具を減らして、設置コストの抑制を図ることのできる屋根瓦を得ることを目的とする。   The present invention has been made in view of the above, and by suppressing damage due to the load from the equipment installed on the roof, it is possible to reduce the number of support brackets necessary for installation of the equipment, thereby reducing the installation cost. The purpose is to obtain roof tiles that can be used.

上述した課題を解決し、目的を達成するために、本発明は、屋根下地上に葺かれる屋根瓦であって、屋根下地と対向する対向面を有する板部と、板部の対向面に突出形成されて、棟側から軒側に向けて延びるリブと、を備えることを特徴とする。   In order to solve the above-described problems and achieve the object, the present invention is a roof tile that is laid on a roof base, and has a plate portion having an opposing surface facing the roof base, and projects from the opposing surface of the plate portion. And a rib that is formed and extends from the ridge side toward the eaves side.

本発明にかかる屋根瓦によれば、屋根上に設置された設備機器からの荷重による破損を抑えることで、設備機器の設置に必要な支持金具を減らして、設置コストの抑制を図ることができるという効果を奏する。   According to the roof tile according to the present invention, it is possible to reduce installation cost by reducing support brackets necessary for installation of equipment by suppressing breakage due to load from equipment installed on the roof. There is an effect.

以下に、本発明の実施の形態にかかる屋根瓦および太陽光発電システムを図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。   Below, the roof tile and photovoltaic power generation system concerning embodiment of this invention are demonstrated in detail based on drawing. Note that the present invention is not limited to the embodiments.

実施の形態１．
図１は、本発明の実施の形態１にかかる屋根瓦を表面側から見た斜視図である。図２は、実施の形態１にかかる屋根瓦を裏面側から見た斜視図である。図３は、実施の形態１にかかる屋根瓦が一部に葺かれた状態の屋根下地を示す図である。図４は、実施の形態１にかかる屋根瓦が葺かれた屋根下地の断面図である。 Embodiment 1 FIG.
FIG. 1 is a perspective view of the roof tile according to the first embodiment of the present invention as seen from the front side. FIG. 2 is a perspective view of the roof tile according to the first embodiment viewed from the back side. FIG. 3 is a diagram illustrating the roof base in a state in which the roof tile according to the first embodiment is partially wound. FIG. 4 is a cross-sectional view of the roof foundation on which the roof tile according to the first embodiment is spread.

本実施の形態１にかかる屋根瓦１は、太陽電池モジュール等の設備機器が設置される屋根に用いられる。屋根瓦は、図１および図２に示すように、平板形状の板部１０を備える。板部１０は、屋根上に葺かれた状態で外側を向く表面１０ａと、屋根下地３と対向する対向面である裏面１０ｂとを有する。板部１０は、一般的な屋根瓦と同様の形状を呈する。   The roof tile 1 according to the first embodiment is used for a roof on which equipment such as a solar cell module is installed. As shown in FIGS. 1 and 2, the roof tile includes a flat plate portion 10. The plate part 10 has a front surface 10 a facing outward when being sown on the roof, and a back surface 10 b which is a facing surface facing the roof base 3. The board part 10 exhibits the same shape as a general roof tile.

板部１０の裏面１０ｂには、リブ１ａが形成されている。リブ１ａは、屋根瓦１を屋根上に設置した状態で、傾斜面の上方となる棟側の端部である棟側端部１０ｃから傾斜面の下方となる軒側の端部である軒側端部１０ｄに向けて延びるように形成される。   Ribs 1 a are formed on the back surface 10 b of the plate portion 10. The rib 1a is an eaves side that is an end of the eaves that is below the inclined surface from the ridge side end 10c that is an end of the ridge that is above the inclined surface in a state in which the roof tile 1 is installed on the roof. It is formed to extend toward the end 10d.

図３に示すように、複数の屋根瓦１が屋根下地３上に並べて設置される。図４に示すように、リブ１ａは、先端が屋根下地３に当接する高さで形成される。また、リブ１ａは、先端の全面で屋根下地３に面接触する。   As shown in FIG. 3, a plurality of roof tiles 1 are installed side by side on a roof base 3. As shown in FIG. 4, the rib 1 a is formed at a height at which the tip abuts against the roof base 3. Moreover, the rib 1a is in surface contact with the roof base | substrate 3 in the whole surface of a front-end | tip.

次に、設備機器である太陽電池モジュール１１を屋根上に固定する支持金具２について説明する。支持金具２は、底面部２ａと腕部２ｂとを有する。底面部２ａは、屋根瓦１の板部１０と屋根下地３との間で、屋根下地３に対して固定される。具体的には、屋根下地３には固定台５が固定され、その固定台５に対して底面部２ａが固定される。底面部２ａは、屋根瓦１の板部１０と屋根下地３との間の空間のうち、軒側端部１０ｄ側に寄せた位置に固定される。   Next, the support metal fitting 2 that fixes the solar cell module 11 as the equipment on the roof will be described. The support fitting 2 has a bottom surface portion 2a and an arm portion 2b. The bottom surface portion 2 a is fixed to the roof base 3 between the plate portion 10 of the roof tile 1 and the roof base 3. Specifically, the fixed base 5 is fixed to the roof base 3, and the bottom surface portion 2 a is fixed to the fixed base 5. The bottom surface portion 2a is fixed at a position close to the eave side end portion 10d side in the space between the plate portion 10 of the roof tile 1 and the roof base 3.

腕部２ｂは、底面部２ａから軒側に延びている。腕部２ｂは、屋根の傾斜方向に隣接する屋根瓦２の隙間から外部に露出し、軒側に配置された屋根瓦１の板部１０の表面１０ａ上に位置する。外部に露出した腕部２ｂに対して、太陽電池モジュール１１が固定されることで、太陽電池モジュール１１が支持金具２に支持される。屋根瓦１と支持金具２と太陽電池モジュール１１とで、太陽光発電システムが構成される。   The arm portion 2b extends from the bottom surface portion 2a to the eaves side. The arm portion 2b is exposed to the outside through a gap between the roof tiles 2 adjacent to each other in the inclination direction of the roof, and is located on the surface 10a of the plate portion 10 of the roof tile 1 disposed on the eaves side. The solar cell module 11 is supported by the support fitting 2 by fixing the solar cell module 11 to the arm 2b exposed to the outside. The roof tile 1, the support fitting 2, and the solar cell module 11 constitute a solar power generation system.

ここで、太陽電池モジュール１１の重量によって腕部２ｂが変形することで、腕部２ｂの下方にある屋根瓦１の板部１０に荷重が加わる場合がある。本実施の形態１にかかる屋根瓦１では、板部１０の裏面１０ｂに形成されたリブ１ａが、屋根下地３に面接触している。そのため、太陽電池モジュール１１の荷重が加わった場合であっても、リブ１ａに支えられることで、板部１０が変形しにくく、屋根瓦１が破損しにくくなっている。すなわち、屋根瓦１の耐荷重性能の向上を図ることができる。   Here, when the arm portion 2b is deformed by the weight of the solar cell module 11, a load may be applied to the plate portion 10 of the roof tile 1 below the arm portion 2b. In the roof tile 1 according to the first embodiment, the rib 1 a formed on the back surface 10 b of the plate portion 10 is in surface contact with the roof base 3. Therefore, even if the load of the solar cell module 11 is applied, the plate part 10 is not easily deformed and the roof tile 1 is not easily damaged by being supported by the rib 1a. That is, the load bearing performance of the roof tile 1 can be improved.

なお、リブ１ａによって板部１０に荷重が加えられる要因としては、太陽電池モジュール１１の重量以外にも、太陽電池モジュール１１に積もった雪の重量または太陽電池モジュール１１に加えられる風圧が挙げられる。   In addition to the weight of the solar cell module 11, the factor that applies a load to the plate portion 10 by the rib 1 a includes the weight of snow accumulated on the solar cell module 11 or the wind pressure applied to the solar cell module 11.

ここで、リブ１ａは、腕部２ｂの直下に形成されることで、板部１０の変形を抑える効果を発揮しやすくなる。ここで、平板形状の板部１０を有する屋根瓦１は、一般的に千鳥葺きで屋根下地３上へ葺かれる。この場合、太陽電池モジュール１１の設置では、屋根の傾斜方向と垂直となる幅方向において働き幅の端部から４分の１となる位置に支持金具２の腕部２ｂが設けられることが多い。そのため、リブ１ａは、屋根の傾斜方向と垂直な方向である板部１０の幅方向において、働き幅の端部から４分の１となる位置に形成されることが好ましい。   Here, the rib 1a is formed directly under the arm portion 2b, so that the effect of suppressing deformation of the plate portion 10 is easily exhibited. Here, the roof tile 1 having the flat plate portion 10 is generally spread on the roof base 3 by staggering. In this case, when the solar cell module 11 is installed, the arm portion 2b of the support metal fitting 2 is often provided at a position that is a quarter from the end portion of the working width in the width direction perpendicular to the inclination direction of the roof. Therefore, it is preferable that the rib 1a is formed in the position which becomes a quarter from the edge part of a working width in the width direction of the board part 10 which is a direction perpendicular | vertical to the inclination direction of a roof.

また、図４に示すように、板部１０の棟側端部１０ｃとリブ１ａとの距離Ｘよりも、板部１０の軒側端部１０ｄとリブ１ａとの距離Ｙのほうを大きくすることで、リブ１ａを支持金具２の腕部２ｂの直下に配置しつつ、リブ１ａの軒側では、支持金具２の底面部２ａとの干渉を回避することができる。   Also, as shown in FIG. 4, the distance Y between the eaves-side end 10d of the plate 10 and the rib 1a is made larger than the distance X between the ridge-side end 10c of the plate 10 and the rib 1a. Thus, it is possible to avoid interference with the bottom surface portion 2a of the support fitting 2 on the eaves side of the rib 1a while arranging the rib 1a directly below the arm portion 2b of the support fitting 2.

また、屋根瓦１の耐荷重性能が向上することで、荷重を分散させるために支持金具２の数を増やす必要がなくなる。そのため、支持金具２の数を減らして、太陽電池モジュール１１の設置作業に必要な工数および使用材料の削減を図って、設置コストの抑制を図ることができる。また、太陽電池モジュール１１の設置作業に必要な工数を削減することで、工期の短縮化を図ることができる。   Moreover, since the load bearing performance of the roof tile 1 is improved, it is not necessary to increase the number of the support fittings 2 in order to disperse the load. Therefore, the number of support fittings 2 can be reduced to reduce the number of man-hours and materials used for the installation work of the solar cell module 11, and the installation cost can be suppressed. Moreover, the construction period can be shortened by reducing the number of man-hours required for the installation work of the solar cell module 11.

また、屋根瓦１の板部１０は、一般的な屋根瓦と同様の形状を呈しているため、太陽電池モジュール１１が設置されない屋根にも用いることができるため、汎用性が向上する。これにより、市場での流通量の向上によって生産量を増やしやすくなり、製造コストの抑制を図ることが可能となる。   Moreover, since the plate | board part 10 of the roof tile 1 is exhibiting the same shape as a general roof tile, since it can be used also for the roof in which the solar cell module 11 is not installed, versatility improves. Thereby, it becomes easy to increase production volume by the improvement of the distribution | circulation amount in a market, and it becomes possible to aim at suppression of manufacturing cost.

また、リブ１ａが棟側から軒側に向けて延びているため、屋根瓦１と屋根下地３との間に雨水が侵入した場合に、屋根下地３上を流れる雨水がリブ１ａによって堰き止められにくくなる。したがって、軒側への雨水の円滑な排水を行うことができる。   Further, since the rib 1a extends from the ridge side toward the eaves side, when rainwater enters between the roof tile 1 and the roof base 3, the rain water flowing on the roof base 3 is blocked by the rib 1a. It becomes difficult. Therefore, smooth drainage of rain water to the eaves side can be performed.

なお、リブ１ａの形状は、屋根下地３に面接触する形状であれば、その形状は問わない。また、リブ１ａと支持金具２とが干渉してしまった場合には、リブ１ａの一部を削って屋根瓦１を設けてもよい。   In addition, if the shape of the rib 1a is a shape which carries out surface contact with the roof base | substrate 3, the shape will not be ask | required. Moreover, when the rib 1a and the support metal fitting 2 interfere, a part of rib 1a may be shaved and the roof tile 1 may be provided.

また、屋根瓦１の材料は、陶器とセメントの使用が想定されるが、セメントを用いることで寸法のばらつきを抑えることができる。   Moreover, although the use of pottery and cement is assumed for the material of the roof tile 1, the dispersion | variation in a dimension can be suppressed by using cement.

図５は、実施の形態１の変形例１にかかる屋根瓦１が葺かれた屋根下地３の断面図である。図６は、図５に示すＡ−Ａ線に沿った矢視断面図である。図７は、実施の形態１の変形例１にかかる屋根瓦１と屋根下地３との間に差し込まれる間隙充填部７の斜視図である。   FIG. 5 is a cross-sectional view of the roof base 3 on which the roof tile 1 according to the first modification of the first embodiment is spread. 6 is a cross-sectional view taken along the line AA shown in FIG. FIG. 7 is a perspective view of the gap filling portion 7 that is inserted between the roof tile 1 and the roof base 3 according to the first modification of the first embodiment.

変形例１にかかる屋根瓦１では、リブ１ａの先端が屋根下地３に当接しない高さで形成されており、リブ１ａの先端と屋根下地３との間に隙間が形成されている。本変形例１では、図７に示すような楔形の間隙充填部７を、リブ１ａの先端と屋根下地３との間に差し込んで隙間を充填している。これにより、屋根瓦１の板部１０に荷重が加わった場合であっても、リブ１ａで支えることが可能となり、屋根瓦１の耐荷重性能の向上を図ることができる。   In the roof tile 1 according to the first modification, the tip of the rib 1 a is formed at a height that does not contact the roof base 3, and a gap is formed between the tip of the rib 1 a and the roof base 3. In the first modification, a wedge-shaped gap filling portion 7 as shown in FIG. 7 is inserted between the tip of the rib 1a and the roof base 3 to fill the gap. Thereby, even when a load is applied to the plate portion 10 of the roof tile 1, it can be supported by the rib 1a, and the load bearing performance of the roof tile 1 can be improved.

また、屋根瓦１の寸法のばらつき、および設置時の誤差によって、リブ１ａと屋根下地３との間に隙間ができた場合であっても、間隙充填部７を差し込むことで、屋根瓦１の耐荷重性能の向上を図ることができる。また、間隙充填部７が楔形の形状を呈しているため、リブ１ａと屋根下地３との隙間の大きさにばらつきがあった場合にも、リブ１ａと屋根下地３の両方に当接するまで間隙充填部７を差し込むことで、板部１０をリブ１ａで支えることによる屋根瓦１の耐荷重性能の向上を図ることができる。   Further, even when a gap is formed between the rib 1a and the roof base 3 due to variations in dimensions of the roof tile 1 and an error during installation, the gap filling portion 7 is inserted, so that the roof tile 1 The load bearing performance can be improved. In addition, since the gap filling portion 7 has a wedge shape, even when the gap between the rib 1a and the roof base 3 has a variation in size, the gap is filled until the rib 1a and the roof base 3 come into contact with each other. By inserting the filling portion 7, it is possible to improve the load bearing performance of the roof tile 1 by supporting the plate portion 10 with the rib 1a.

図８は、実施の形態１の変形例２にかかる屋根瓦１を裏面１０ｂ側から見た斜視図である。図９は、実施の形態１の変形例２にかかる屋根瓦１を屋根の傾斜方向に沿って見た断面図である。   FIG. 8 is a perspective view of the roof tile 1 according to the second modification of the first embodiment when viewed from the back surface 10b side. FIG. 9 is a cross-sectional view of the roof tile 1 according to the second modification of the first embodiment when viewed along the inclination direction of the roof.

変形例２にかかる屋根瓦１の板部１０は、幅方向の中央部のほうが端部よりも屋根下地３に近くなる凹形状を呈する。板部１０が凹形状を呈する屋根瓦１は、一般的に筋葺きで屋根下地３上へ葺かれる。この場合、太陽電池モジュール１１の設置では、幅方向において中央部に支持金具２の腕部２ｂが設けられることが多い。したがって、板部１０が凹形状を呈する屋根瓦１では、図８および図９に示すように、板部１０の幅方向において中央部となる位置にリブ１ａが形成されることが好ましい。   The plate part 10 of the roof tile 1 according to the modified example 2 has a concave shape in which the central part in the width direction is closer to the roof base 3 than the end part. The roof tile 1 in which the plate portion 10 has a concave shape is generally placed on the roof base 3 by scoring. In this case, when the solar cell module 11 is installed, the arm portion 2b of the support metal fitting 2 is often provided at the center in the width direction. Therefore, in the roof tile 1 in which the plate portion 10 has a concave shape, it is preferable that the rib 1a is formed at a position that becomes the central portion in the width direction of the plate portion 10 as shown in FIGS.

以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。   The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
