Also, the side edge of the light shelf on the window side is supported by a vertical rod fixed to the outer wall, the outer side edge is supported by a vertical rod, and the connecting portion of the rods can be rotated. The light shelf can be tilted because it has a simple link structure, but because the depth dimension of the light shelf is short, even if the light shelf is raised to a vertical position, the upper part of the window cannot be closed and indoors There was a problem that it was not possible to block direct light. In addition, since the movable part of the light shelf is installed outdoors, the movable part needs strength for wind resistance, resulting in high costs and problems with durability.

本発明は、上記に鑑みてなされたものであって、低コストで建築物の意匠性が損なわれず、かつ、窓上部を殆んど閉状態にして室内への直射光の入射を遮ることができるライトシェルフを備えた建築物を得ることを目的とする。   The present invention has been made in view of the above, and the design of the building is not impaired at a low cost, and the upper part of the window is almost closed to block the incidence of direct light into the room. The purpose is to obtain a building with a light shelf that can.

上述した課題を解決し、目的を達成するために、本発明の建築物は、外壁に設けられた窓と、前記窓の内側の高さ方向中間部に回動支点が設置され、略水平内向き位置から、窓上部を遮蔽する上向き位置まで間の角度位置に傾斜調節可能なライトシェルフと、を備えたことを特徴とする。   In order to solve the above-described problems and achieve the object, the building of the present invention has a window provided on the outer wall, and a rotation fulcrum installed in the middle in the height direction inside the window. And a light shelf capable of adjusting the inclination to an angular position between an orientation position and an upward position that shields the upper portion of the window.

本発明の建築物は、窓上部から入射する直射光を、庇や垂直ルーバー等を必要とせずに、直射光の仰角にかかわらず、ライトシェルフだけで遮ることができる。   The building of the present invention can block the direct light incident from the upper part of the window only by the light shelf, regardless of the elevation angle of the direct light, without requiring a ridge or a vertical louver.

本発明により、低コストで意匠性が損なわれず、かつ、窓上部を殆んど閉状態にして室内への直射光の入射を遮ることができる建築物が得られる。   According to the present invention, it is possible to obtain a building that is inexpensive and does not impair the design, and that can block the direct light from entering the room with the upper part of the window almost closed.

以下に、本発明に係る建築物の実施例を図面に基づいて詳細に説明する。なお、この実施例によりこの発明が限定されるものではない。   Below, the Example of the building which concerns on this invention is described in detail based on drawing. Note that the present invention is not limited to the embodiments.

図1は、本発明に係る建築物の実施例を示す縦断面図である。   FIG. 1 is a longitudinal sectional view showing an embodiment of a building according to the present invention.

建築物10の外壁11には、縦方向が、腰壁11aの上端から天井13に亘り、横方向が室14の略全幅に亘る矩形の窓20が設けられている。窓20の高さ方向中間部に、窓上部としての上窓22と、窓下部としての下窓21とを仕切る窓桟23が設けられている。床12からの天井高さは2700〜3000mm程度、床12からの窓桟23の高さは1850〜2100mm程度、上窓22の開口高さは600〜1000mm程度としている。上窓22は単板透明ガラス、下窓21はペアガラス等の省エネガラスとなっている。   The outer wall 11 of the building 10 is provided with a rectangular window 20 in which the vertical direction extends from the upper end of the waist wall 11 a to the ceiling 13 and the horizontal direction extends over substantially the entire width of the chamber 14. A window bar 23 that partitions an upper window 22 as an upper window portion and a lower window 21 as a lower window portion is provided at an intermediate portion in the height direction of the window 20. The ceiling height from the floor 12 is about 2700 to 3000 mm, the height of the window bar 23 from the floor 12 is about 1850 to 2100 mm, and the opening height of the upper window 22 is about 600 to 1000 mm. The upper window 22 is a single plate transparent glass, and the lower window 21 is an energy saving glass such as a pair glass.

窓桟23の室内側にはライトシェルフ30の回動支点31が設置されている。ライトシェルフ30の奥行きおよび幅は、上窓22の開口高さおよび幅と略同じに形成されている。ライトシェルフ30の上面は光反射機能を有し、天井13は、高反射率の仕上材により光散乱機能を有している。床12からの窓桟23の高さ(回動支点31の高さ)を、1800mmを超える高さとすることにより、ライトシェルフ30を設置しても、室14からの上方視界のよい建築物とすることができる。   A rotation fulcrum 31 of the light shelf 30 is installed on the indoor side of the window bar 23. The depth and width of the light shelf 30 are formed substantially the same as the opening height and width of the upper window 22. The upper surface of the light shelf 30 has a light reflecting function, and the ceiling 13 has a light scattering function by a finishing material having a high reflectance. By setting the height of the window sill 23 from the floor 12 (the height of the rotation fulcrum 31) to a height exceeding 1800 mm, even if the light shelf 30 is installed, the building has a good upward view from the room 14 can do.

ライトシェルフ30の回動支点31の反対側には吊り紐32の一端が結び付けられ、吊り紐32の他端は、上窓22と天井13の隅部に設置された電動リール33に巻き取られている。電動リール33の巻き取り量を調節することにより、ライトシェルフ30を、図1に示す略水平内向き位置から、窓上部としての上窓22を遮蔽する上向き位置までの角度位置に傾斜調節可能となっている。窓桟23からブラインド40を吊り下げ、下窓21から入射する直射光を遮るようにする。   One end of a hanging strap 32 is tied to the opposite side of the rotation fulcrum 31 of the light shelf 30, and the other end of the hanging strap 32 is wound around an electric reel 33 installed at the corner of the upper window 22 and the ceiling 13. ing. By adjusting the winding amount of the electric reel 33, the inclination of the light shelf 30 can be adjusted from the substantially horizontal inward position shown in FIG. 1 to the upward position that shields the upper window 22 as the upper part of the window. It has become. The blind 40 is suspended from the window bar 23 to block direct light incident from the lower window 21.

天井13には、照度調整可能なHf照明器具50およびインテリジェント照度センサー51を設置し、窓20からの採光により室14が予め定めた明るさ以上になると、インテリジェント照度センサー51がこれを検知して、Hf照明器具50への供給電力を絞り、省エネを図るようになっている。   An Hf lighting fixture 50 and an intelligent illuminance sensor 51 that can adjust the illuminance are installed on the ceiling 13, and when the room 14 becomes more than a predetermined brightness due to the lighting from the window 20, the intelligent illuminance sensor 51 detects this. The power supplied to the Hf lighting fixture 50 is reduced to save energy.

次に、上記のように構成された建築物の採光および遮光方法について説明する。日中、仰角が略45°以上の高い角度から直射光60が上窓22に照射されるときは、ライトシェルフ30を図1に示す略水平内向き位置とし、ライトシェルフ30の上面で直射光60を天井13に向けて反射させ、天井13で散乱光として室内照明光として利用し、Hf照明器具50への供給電力を絞ることにより省エネを図る。   Next, the lighting and shading methods of the building configured as described above will be described. When the direct light 60 is applied to the upper window 22 from a high angle of elevation of approximately 45 ° or more during the day, the light shelf 30 is set to a substantially horizontal inward position shown in FIG. Energy saving is achieved by reflecting 60 toward the ceiling 13, using the ceiling 13 as scattered light as room illumination light, and reducing the power supplied to the Hf lighting fixture 50.

朝夕および冬の日中に、仰角が略45°以下の低い角度から直射光61が上窓22に照射されるときは、ライトシェルフ30が図1に示す水平内向き位置では、直射光61がライトシェルフ30に反射されずに室14内に照射され、グレアを引き起こすので、直射光61の入射角度に応じてライトシェルフ30を上向きに傾斜させ、直射光61の室14内への入射を防止する。   When the direct light 61 is irradiated on the upper window 22 from morning, evening and winter days when the elevation angle is as low as approximately 45 ° or less, the direct light 61 is at the horizontal inward position shown in FIG. Since it is irradiated into the chamber 14 without being reflected by the light shelf 30 and causes glare, the light shelf 30 is inclined upward according to the incident angle of the direct light 61 to prevent the direct light 61 from entering the chamber 14. To do.

また、夏の室内冷房時には、ライトシェルフ30を上向き位置とし、上窓22から入射する直射光を全て屋外へ反射させて室14内の日射負荷を低減させ、冷房電力を低減させる。なお、下窓21からの直射光は、ブラインド40により遮光することができる。   Further, during indoor indoor cooling, the light shelf 30 is set to the upward position, and all direct light incident from the upper window 22 is reflected to the outside to reduce the solar radiation load in the room 14 and to reduce the cooling power. The direct light from the lower window 21 can be blocked by the blind 40.

以上説明したライトシェルフ30を備えた建築物10は、窓上部としての上窓22から入射する直射光を、庇や垂直ルーバー等を必要とせずに、直射光の仰角にかかわらず、ライトシェルフ30だけで遮ることができ低コストである。また、窓20の外側に庇やライトシェルフを設置しないので建築物の意匠性が損なわれない。また、ライトシェルフ30の可動部が室14内に設置されているので耐久性に優れ、かつ、低コストである。   In the building 10 having the light shelf 30 described above, the direct light that is incident from the upper window 22 as the upper part of the window does not require a ridge or a vertical louver, regardless of the elevation angle of the direct light. It can be blocked only by low cost. In addition, since no fence or light shelf is installed outside the window 20, the design of the building is not impaired. Moreover, since the movable part of the light shelf 30 is installed in the chamber 14, the durability is excellent and the cost is low.

なお、この実施例では、窓20の高さ方向中間部に、窓上部としての上窓22と、窓下部としての下窓21とを仕切る窓桟23を設けたが、窓20は窓桟23のない一枚窓とし、ライトシェルフ30の支点31は、左右の仕切壁等に設置してもよい。また、電動リール33は、ロープ等で駆動する手動リールとしてもよいし、リールと吊り紐32によらずに、回動支点31を直接回動駆動するようにしてもよい。また、下窓21は省エネガラスでなくてもよい。   In this embodiment, the window frame 23 that partitions the upper window 22 as the upper part of the window and the lower window 21 as the lower part of the window is provided in the middle part in the height direction of the window 20. The fulcrum 31 of the light shelf 30 may be installed on the left and right partition walls. The electric reel 33 may be a manual reel that is driven by a rope or the like, or the rotation fulcrum 31 may be directly driven to rotate without using the reel and the hanging strap 32. The lower window 21 may not be energy saving glass.

以上のように、本発明にかかる建築物は、低コストで意匠性の高い省エネ型建築物であり、学校、病院、事務所、店舗、住宅等の建築物として有用である。   As described above, the building according to the present invention is an energy-saving building with low cost and high design, and is useful as a building such as a school, a hospital, an office, a store, and a house.
