Description

特許法第３０条第２項適用 平成２９年７月１日 一般社団法人 建築設備綜合協会 発行「ＢＥ建築設備、第６８巻７号、第６３～６８頁」にて公開Application of Article 30, Paragraph 2 of the Patent Act July 1, 2017 Published in "BE Building Equipment, Vol. 68, No. 7, pp. 63-68" issued by the Building Equipment General Incorporated Association.

本発明は、外装シェードに関する。 The present invention relates to an exterior shade.

建物内部に差込む直射日光を遮光する機構として、外装シェードやルーバー、庇等が知られている。例えば特許文献１には、開孔パターンの異なる２枚のパンチングメタルから成る遮光装置によって直射日光を遮光する構成が開示されている。また、特許文献２には、建物の外壁に設けられた開口部の内壁面を傾斜させることにより、眺望を確保しつつ直射日射の取り込みを抑制する構成が開示されている。 Exterior shades, louvers, eaves, etc. are known as mechanisms that block direct sunlight from entering the building. For example, Patent Document 1 discloses a configuration in which direct sunlight is shielded by a light-shielding device composed of two punching metals having different opening patterns. Further, Patent Document 2 discloses a configuration in which the inner wall surface of an opening provided in the outer wall of a building is inclined to suppress the intake of direct sunlight while ensuring a view.

特開２０１７－６６６１４号公報Japanese Unexamined Patent Publication No. 2017-66614 特開２０１７－６６６８７号公報Japanese Unexamined Patent Publication No. 2017-66687

近年、上記の外装シェード等には、直射日光を遮光する機能の他、建物内部の環境をより快適にするため、日射による熱負荷の軽減、間接光の導入、眺望の確保、視線の遮蔽等の様々な機能が求められている。しかしながら、特許文献１に示す遮光装置や特許文献２に示す開口部は、上記の様々な機能を持ち合わせてはいなかった。 In recent years, in addition to the function of blocking direct sunlight, the above-mentioned exterior shades, etc. have reduced the heat load due to solar radiation, introduced indirect light, secured the view, shielded the line of sight, etc. in order to make the environment inside the building more comfortable. Various functions are required. However, the light-shielding device shown in Patent Document 1 and the opening shown in Patent Document 2 do not have the above-mentioned various functions.

本発明は上記事実に鑑み、直射日光を遮光しつつ、建物内部に間接光をより導入することができる外装シェードを提供することを目的とする。 In view of the above facts, it is an object of the present invention to provide an exterior shade capable of introducing indirect light into the inside of a building while blocking direct sunlight.

第一態様に記載の外装シェードは、建物の外面を覆う壁体に複数の開口部が形成された外装シェードであって、前記開口部の前記壁体における外側の開口面の外開口面積は、前記壁体における内側の開口面の内開口面積より小さく、前記壁体を正面視した場合に、前記内側の開口面と前記外側の開口面とが略重ならず、前記内側の開口面の中心は前記外側の開口面の中心に対して上下かつ左右にずれた位置とされる。 The exterior shade according to the first aspect is an exterior shade in which a plurality of openings are formed in a wall body covering the outer surface of a building, and the outer opening area of the outer opening surface in the wall body of the opening is set. It is smaller than the inner opening area of the inner opening surface in the wall body, and when the wall body is viewed from the front, the inner opening surface and the outer opening surface do not substantially overlap, and the center of the inner opening surface. Is positioned vertically and horizontally offset from the center of the outer opening surface.

上記構成によれば、壁体を正面視した場合に、内側の開口面と外側の開口面とが略重ならず、内側の開口面の中心が外側の開口面の中心に対して上下かつ左右にずれた位置とされる。このため、外側の開口面から開口部に入射した日射が、内側の開口面から建物内部に直接差込むことを抑制することができる。 According to the above configuration, when the wall body is viewed from the front, the inner opening surface and the outer opening surface do not substantially overlap, and the center of the inner opening surface is vertically and horizontally with respect to the center of the outer opening surface. It is said that the position is shifted to. Therefore, it is possible to prevent the solar radiation incident on the opening from the outer opening surface from directly entering the inside of the building from the inner opening surface.

また、開口部の外開口面積が内開口面積より小さいため、開口部の内周面（小口面）で日射を反射させて建物内部に間接光として導入することができる。なお、本発明において、「略重ならず」とは、全く重ならない構成（正面開口率が０％）の他、僅かに重なる構成（正面開口率１０％以下）を含んでいる。 Further, since the outer opening area of the opening is smaller than the inner opening area, it is possible to reflect the sunlight on the inner peripheral surface (edge surface) of the opening and introduce it as indirect light into the building. In the present invention, "not substantially overlapping" includes a configuration in which they do not overlap at all (front aperture ratio is 0%) and a configuration in which they slightly overlap (front opening ratio is 10% or less).

第二態様に記載の外装シェードは、第一態様に記載の外装シェードであって、前記壁体を前記建物の南側に取付けた際に、前記内側の開口面の中心は前記外側の開口面の中心に対して上方かつ西方にずれた位置とされる。 The exterior shade according to the second aspect is the exterior shade according to the first aspect , and when the wall body is attached to the south side of the building, the center of the inner opening surface is the center of the outer opening surface. It is considered to be located above and west of the center.

上記構成によれば、外装シェードを建物の南側に取付けた際に、内側の開口面の中心が外側の開口面の中心に対して上方かつ西方にずれた位置とされる。このため、上方から開口部に入射する真夏の日射、及び西方から開口部に入射する西日が内側の開口面から建物内部に直接差込むことを抑制することができ、建物内部の環境をより快適にすることができる。なお、本発明において、「南側」とは、真南側の他、南西側や西南西側等を含んでいる。 According to the above configuration, when the exterior shade is attached to the south side of the building, the center of the inner opening surface is positioned upward and westward with respect to the center of the outer opening surface. For this reason, it is possible to suppress the midsummer sunlight incident on the opening from above and the west sun incident on the opening from the west directly into the inside of the building from the inner opening surface, which further improves the environment inside the building. Can be comfortable. In the present invention, the "south side" includes the southwest side, the west-southwest side, and the like in addition to the true south side.

第三態様に記載の外装シェードは、請求項１又は２に記載の外装シェードであって、前記内側の開口面及び前記外側の開口面は、四角形状とされており、互いに相似形状とされている。 The exterior shade according to the third aspect is the exterior shade according to claim 1 or 2, wherein the inner opening surface and the outer opening surface have a square shape and are similar to each other. There is.

上記構成によれば、内側の開口面と外側の開口面とが、四角形状とされ、互いに相似形状とされている。このため、開口面が円形状である場合や非相似形状である場合と比較して、開口部の施工性を向上させることができる。 According to the above configuration, the inner opening surface and the outer opening surface have a square shape and are similar to each other. Therefore, the workability of the opening can be improved as compared with the case where the opening surface has a circular shape or a dissimilar shape.

本発明によれば、直射日光を遮光しつつ、建物内部に間接光をより導入することができる。 According to the present invention, indirect light can be further introduced into the building while blocking direct sunlight.

以下、本発明の実施形態の一例における外装シェードについて、図１～図３を用いて説明する。 Hereinafter, the exterior shade in an example of the embodiment of the present invention will be described with reference to FIGS. 1 to 3.

（構成）
外装シェード１０は、建物１２の外面を覆うものであり、図１（Ａ）に示すように、矩形状の建物１２の一面に取付けられている。なお、本実施形態では、建物１２の窓面は西南西方向を向いており、建物１２の西南西側の外面全体が外装シェード１０によって覆われている。 (Constitution)
The exterior shade 10 covers the outer surface of the building 12, and is attached to one surface of the rectangular building 12 as shown in FIG. 1 (A). In the present embodiment, the window surface of the building 12 faces the west-southwest direction, and the entire outer surface of the building 12 on the west-southwest side is covered with the exterior shade 10.

図１（Ａ）及び図１（Ｂ）に示すように、外装シェード１０は、建物１２の外面を覆う壁体１４と、壁体１４に形成された複数の開口部１６と、を有している。壁体１４は、例えば厚さがｔとされたＧＲＣ（ガラス繊維強化セメント）パネルから成り、正面視で矩形状とされている。 As shown in FIGS. 1A and 1B, the exterior shade 10 has a wall body 14 that covers the outer surface of the building 12 and a plurality of openings 16 formed in the wall body 14. There is. The wall body 14 is made of, for example, a GRC (glass fiber reinforced cement) panel having a thickness of t, and has a rectangular shape when viewed from the front.

開口部１６は、壁体１４を厚さ方向に貫通しており、壁体１４の外側、すなわち建物１２に面する面とは反対側の面、及び壁体１４の内側、すなわち建物１２に面する面にそれぞれ開口面１８、２０を有している。また、複数の開口部１６は、壁体１４全体に等間隔に形成されており、全て同一形状とされている。なお、壁体１４における開口部１６の数や間隔は、開口率に応じて定められている。 The opening 16 penetrates the wall 14 in the thickness direction, and the outside of the wall 14, that is, the surface opposite to the surface facing the building 12, and the inside of the wall 14, that is, the surface of the building 12. The surface to be used has openings 18 and 20, respectively. Further, the plurality of openings 16 are formed at equal intervals in the entire wall body 14, and all have the same shape. The number and spacing of the openings 16 in the wall 14 are determined according to the aperture ratio.

本実施形態では、内側の開口面１８及び外側の開口面２０はそれぞれ四角形状とされており、互いに相似形状とされている。また、外側の開口面２０の開口面積（外開口面積）は、内側の開口面１８の開口面積（内開口面積）より小さくされている。 In the present embodiment, the inner opening surface 18 and the outer opening surface 20 have a square shape, respectively, and have similar shapes to each other. Further, the opening area (outer opening area) of the outer opening surface 20 is smaller than the opening area (inner opening area) of the inner opening surface 18.

さらに、壁体１４を正面視した場合に、内側の開口面１８と外側の開口面２０とが略重ならず、内側の開口面１８の中心が外側の開口面２０の中心に対して上下かつ左右にずれた位置とされている。具体的には、壁体１４を建物１２の西南西側（南側）に取付けた際に、内側の開口面１８の中心が外側の開口面２０の中心に対して上方かつ西方にずれた位置とされている。 Further, when the wall body 14 is viewed from the front, the inner opening surface 18 and the outer opening surface 20 do not substantially overlap, and the center of the inner opening surface 18 is vertically and vertically with respect to the center of the outer opening surface 20. The position is shifted to the left and right. Specifically, when the wall body 14 is attached to the west-southwest side (south side) of the building 12, the center of the inner opening surface 18 is positioned upward and westward with respect to the center of the outer opening surface 20. ing.

より具体的に説明すると、図２に示すように、外側の開口面２０の寸法をａ×ｂとした場合に、内側の開口面１８の寸法はａ×ｂよりそれぞれの寸法が大きいｃ×ｄとされている。また、壁体１４を正面視した場合に、内側の開口面１８の中心Ｐは、外側の開口面２０の中心Ｑに対して上方にｍずれ、かつ西方（図２における左方）にｎずれた位置とされている。 More specifically, as shown in FIG. 2, when the dimension of the outer opening surface 20 is a × b, the dimension of the inner opening surface 18 is c × d, which is larger than a × b. It is said that. Further, when the wall body 14 is viewed from the front, the center P of the inner opening surface 18 is shifted upward by m with respect to the center Q of the outer opening surface 20, and is shifted to the west (left in FIG. 2) by n. It is said to be in the same position.

（作用及び効果）
本実施形態の外装シェード１０によれば、壁体１４を正面視した場合に、内側の開口面１８と外側の開口面２０とが略重ならない位置とされている。このため、外側の開口面２０から開口部１６に入射した日射が、内側の開口面１８から建物１２内部に直接差込むことを抑制することができ、太陽の直達光による建物１２への熱負荷を低減することができる。 (Action and effect)
According to the exterior shade 10 of the present embodiment, the inner opening surface 18 and the outer opening surface 20 do not substantially overlap when the wall body 14 is viewed from the front. Therefore, it is possible to prevent the solar radiation incident on the opening 16 from the outer opening surface 20 from directly entering the inside of the building 12 from the inner opening surface 18, and the heat load on the building 12 due to the direct light of the sun. Can be reduced.

特に本実施形態の外装シェード１０によれば、開口部１６の内側の開口面１８の中心Ｐが外側の開口面２０の中心Ｑに対して上方にずれた位置とされている。このため、図３（Ａ）に示すように、上方から開口部１６に入射する日射が内側の開口面１８を通して建物１２内部に直接差込むことを抑制することができる。 In particular, according to the exterior shade 10 of the present embodiment, the center P of the opening surface 18 inside the opening 16 is positioned upward with respect to the center Q of the opening surface 20 outside. Therefore, as shown in FIG. 3A, it is possible to prevent sunlight incident on the opening 16 from above from directly entering the inside of the building 12 through the inner opening surface 18.

なお、例えば真夏（７月２３日）において、太陽の高度は最も高い位置で７４．２度（１２時）、最も低い位置で３３．０度（１６時）となる。このため、内側の開口面１８の位置は、最も高度が低い太陽からの日射、すなわち高度３３．０度以上の日射をカットすることができる位置とされていることが好ましい。 For example, in midsummer (July 23), the altitude of the sun is 74.2 degrees (12:00) at the highest position and 33.0 degrees (16:00) at the lowest position. Therefore, it is preferable that the position of the inner opening surface 18 is a position capable of cutting the sunlight from the sun having the lowest altitude, that is, the sunlight having an altitude of 33.0 degrees or higher.

また、本実施形態の外装シェード１０によれば、開口部１６の内側の開口面１８の中心Ｐが外側の開口面２０の中心Ｑに対して西方にずれた位置とされている。このため、図３（Ｂ）に示すように、西方から開口部１６に入射する日射（西日）が内側の開口面１８を通して建物１２内部に直接差込むことを抑制することができる。 Further, according to the exterior shade 10 of the present embodiment, the center P of the opening surface 18 inside the opening 16 is positioned westward with respect to the center Q of the opening surface 20 outside. Therefore, as shown in FIG. 3B, it is possible to prevent the sunlight (western sun) incident on the opening 16 from the west from directly entering the inside of the building 12 through the inner opening surface 18.

なお、例えば真夏（７月２３日）において、１６時時点の太陽方位角は９２．３度となる。このため、内側の開口面１８の位置は、少なくとも太陽方位角９２．３度以上の日射をカットすることができる位置とされていることが好ましい。 For example, in midsummer (July 23), the solar azimuth angle at 16:00 is 92.3 degrees. Therefore, it is preferable that the position of the inner opening surface 18 is a position capable of cutting solar radiation having a solar azimuth angle of at least 92.3 degrees.

また、本実施形態の外装シェード１０によれば、外側の開口面２０の開口面積（外開口面積）が、内側の開口面１８の開口面積（内開口面積）より小さくされている。このため、開口部１６の内周面２２（小口面）で日射を反射させて、建物１２内部に間接光として導入することができる。すなわち、日射遮蔽効果を妨げない範囲で間接光を建物１２内部に多く取込むことができるため、建物１２内部の明るさが増し、建物１２内部の環境をより快適にすることができる。 Further, according to the exterior shade 10 of the present embodiment, the opening area (outer opening area) of the outer opening surface 20 is smaller than the opening area (inner opening area) of the inner opening surface 18. Therefore, the sunlight can be reflected by the inner peripheral surface 22 (edge surface) of the opening 16 and introduced as indirect light into the building 12. That is, since a large amount of indirect light can be taken into the inside of the building 12 within a range that does not interfere with the sunlight shielding effect, the brightness inside the building 12 can be increased and the environment inside the building 12 can be made more comfortable.

また、本実施形態の外装シェード１０によれば、内側の開口面１８及び外側の開口面２０が、それぞれ四角形状とされ、互いに相似形状とされている。このため、開口面１８、２０が円形状である場合や非相似形状である場合と比較して、開口部１６の施工性を向上させることができる。 Further, according to the exterior shade 10 of the present embodiment, the inner opening surface 18 and the outer opening surface 20 are each shaped like a square and have similar shapes to each other. Therefore, the workability of the opening 16 can be improved as compared with the case where the opening surfaces 18 and 20 have a circular shape or a dissimilar shape.

（その他の実施形態）
以上、本発明について実施形態の一例を説明したが、本発明はかかる実施形態に限定されるものではなく、本発明の範囲内にて他の種々の実施形態が可能である。 (Other embodiments)
Although an example of the embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and various other embodiments are possible within the scope of the present invention.

例えば本実施形態では、建物１２の西南西側の外面に外装シェード１０が取付けられていたが、西南西側には限られず、建物１２のどの方位の外面に外装シェード１０が取付けられていてもよい。 For example, in the present embodiment, the exterior shade 10 is attached to the outer surface on the west-southwest side of the building 12, but the exterior shade 10 is not limited to the west-southwest side, and the exterior shade 10 may be attached to the outer surface in any direction of the building 12.

また、本実施形態では、開口部１６の内側の開口面１８及び外側の開口面２０がそれぞれ四角形状とされ、互いに相似形状とされていた。しかし、内側の開口面１８及び外側の開口面２０の形状は上記実施形態には限られず、例えば一方が円形状、他方が四角形状等とされていてもよい。 Further, in the present embodiment, the inner opening surface 18 and the outer opening surface 20 of the opening 16 have a square shape, respectively, and have similar shapes to each other. However, the shapes of the inner opening surface 18 and the outer opening surface 20 are not limited to the above-described embodiment, and for example, one may be circular and the other may be square.

以下、本発明の実施例及び比較例について説明する。なお、本発明は以下の実施例に限定されるものではない。 Hereinafter, examples and comparative examples of the present invention will be described. The present invention is not limited to the following examples.

（実施例１）
実施例１では、外装シェードの開口部の外側の開口面の寸法について、ａ×ｂ＝１４０ｍｍ×１４０ｍｍ、内側の開口面の寸法について、ｃ×ｄ＝１８０ｍｍ×１８０ｍｍ、中心ＰＱ間の距離について、ｍ＝８５ｍｍ、ｎ＝１２０ｍｍとした。 (Example 1)
In Example 1, the dimensions of the outer opening surface of the opening of the exterior shade are a × b = 140 mm × 140 mm, the dimensions of the inner opening surface are c × d = 180 mm × 180 mm, and the distance between the central PQs. It was set to m = 85 mm and n = 120 mm.

また、壁体の厚さｔ＝１３０ｍｍとし、内側開口率、すなわち外装シェードの壁体の面積に対する内開口面積の総和の割合を３８．９３％とした。このとき、正面開口率、すなわち外装シェードの壁体を正面視した場合の壁体の面積に対する内側の開口面と外側の開口面との重なりの総和の割合は、３．６６％であった。 Further, the thickness t of the wall body was set to 130 mm, and the inner aperture ratio, that is, the ratio of the total inner opening area to the area of the wall body of the exterior shade was set to 38.93%. At this time, the front aperture ratio, that is, the ratio of the total of the overlap between the inner opening surface and the outer opening surface to the area of the wall body when the wall body of the exterior shade was viewed from the front was 3.66%.

（比較例１）
比較例１では、外装シェードの開口部の外側の開口面の寸法について、ａ×ｂ＝１４０ｍｍ×１４０ｍｍ、内側の開口面の寸法について、ｃ×ｄ＝１４０ｍｍ×１４０ｍｍ、中心ＰＱ間の距離について、ｍ＝０ｍｍ、ｎ＝０ｍｍとした。 (Comparative Example 1)
In Comparative Example 1, the dimensions of the outer opening surface of the opening of the exterior shade are a × b = 140 mm × 140 mm, the dimensions of the inner opening surface are c × d = 140 mm × 140 mm, and the distance between the central PQs. It was set to m = 0 mm and n = 0 mm.

また、壁体の厚さｔ＝１３０ｍｍとし、内側開口率を３９．６４％とした。このとき、正面開口率は、内側開口率と同じ３９．６４％であった。 Further, the thickness of the wall body was t = 130 mm, and the inner aperture ratio was 39.64%. At this time, the front aperture ratio was 39.64%, which was the same as the inner aperture ratio.

（実施例１と比較例１との比較）
外開口面積と内開口面積が同一の大きさとされ、内側の開口面の中心が外側の開口面の中心に対してずれた位置とされていない比較例１では、建物の窓面室内側の平均輝度が３０００ｃｄ／ｍ２以上である領域が多くなった。 (Comparison between Example 1 and Comparative Example 1)
In Comparative Example 1 in which the outer opening area and the inner opening area are the same size and the center of the inner opening surface is not positioned so as to be offset from the center of the outer opening surface, the average on the indoor side of the window surface of the building. There are many areas where the brightness is 3000 cd / m 2 or more.

一方、外開口面積が内開口面積より小さくされ、内側の開口面の中心が外側の開口面の中心に対してずれた位置とされている実施例１では、建物の窓面室内側の平均輝度が３０００ｃｄ／ｍ２以上である領域が、比較例１と比較して少なくなった。 On the other hand, in the first embodiment, in which the outer opening area is smaller than the inner opening area and the center of the inner opening surface is offset from the center of the outer opening surface, the average brightness on the indoor side of the window surface of the building is set. The area where the value is 3000 cd / m 2 or more is smaller than that in Comparative Example 1.

一般的に、建物の窓面室内側の平均輝度が３０００ｃｄ／ｍ２以上の場合、建物の内部に居る人は明順応を起こして手元が暗く見えるため、窓面の輝度を抑えることにより快適な明るさを得ることが可能となる。すなわち、比較例１と比較して、実施例１の方が建物内部の明るさが増し、建物内部の環境をより快適にすることができることが確認できた。 Generally, when the average brightness inside the window surface of a building is 3000 cd / m 2 or more, the person inside the building adapts to the light and looks dark at hand, so it is more comfortable to suppress the brightness of the window surface. It is possible to obtain brightness. That is, it was confirmed that the brightness inside the building was increased in Example 1 as compared with Comparative Example 1, and the environment inside the building could be made more comfortable.
