Description

本発明は、平面視において多角形の外形を有し、所定の方向から風を受ける多層階の建物に関する。   The present invention relates to a multi-story building having a polygonal outer shape in plan view and receiving wind from a predetermined direction.

近年、都市化の進展に伴って、都市部では、ヒートアイランド現象が顕著になっている。ヒートアイランド現象を緩和するための対策の１つとして、例えば、海岸沿いの都市部では、海から内陸に吹き込む海風の流れを建物で遮らないように、いわゆる、風の道を確保することが重要である。また、都市部では、高層建築物が密集することにより、ビル風と呼ばれる突風が発生しやすく、風環境（風害）の改善が求められている。   In recent years, with the progress of urbanization, the heat island phenomenon has become prominent in urban areas. As one measure to mitigate the heat island phenomenon, for example, in urban areas along the coast, it is important to secure so-called wind paths so that buildings do not block the flow of sea breeze blowing from the sea to the inland. is there. In urban areas, high-rise buildings are densely packed, and a gust of wind called a building wind is likely to be generated, so that an improvement in wind environment (wind damage) is required.

例えば、特許文献１には、ビル風の発生を抑制し、風通しを良くするために、吹抜け空間を有するブロックを井桁状に積み上げることによって建物の構造体を構成する高層建築物が開示されている。   For example, Patent Literature 1 discloses a high-rise building that forms a building structure by stacking blocks having a stairwell in a cross-girder shape in order to suppress the generation of building wind and improve ventilation. .

特開平６−１７３４７３号公報JP-A-6-173473

しかし、特許文献１に開示された高層建築物は、吹抜け空間の内側に風を流すため、吹抜け空間を居室空間として利用できず、居室空間が制限される、という問題点があった。また、特許文献１に開示された高層建築物は、ブロックを積み上げることで建物の構造体を構成するものであるため、他の建築構造に適用することが難しく、建築構造が制限される、という問題点があった。   However, the high-rise building disclosed in Patent Literature 1 has a problem in that since the wind flows inside the stairwell, the stairwell cannot be used as a living room space, and the living room space is limited. In addition, since the high-rise building disclosed in Patent Document 1 constitutes a building structure by stacking blocks, it is difficult to apply the structure to other building structures, and the building structure is limited. There was a problem.

本発明は、上記問題点を解決するために、居室空間や建築構造に対する制限を緩和し、風の道を確保するとともに、風環境を改善することができる建物を提供することを目的とする。   An object of the present invention is to provide a building capable of relaxing the restrictions on the living room space and the architectural structure, securing a wind path, and improving the wind environment in order to solve the above problems.

本発明は、上記課題を解決するものであって、本発明の一実施形態に係る建物は、
平面視において多角形の外形を有し、所定の方向から風を受ける多層階の建物であって、
前記多角形の各辺に対応する複数の側壁部と、
前記多角形の各頂点に対応する複数の角部と、を備え、
前記複数の角部は、
前記風の風上側に配置された風上側角部と、
前記風の風下側に配置された風下側角部と、
前記風上側角部及び前記風下側角部を除く前記角部に対して前記建物の高さ方向に隅切りした隅切り角部と、を含む、ことを特徴とする。 The present invention solves the above problems, and a building according to an embodiment of the present invention is:
A multi-story building having a polygonal outer shape in a plan view and receiving wind from a predetermined direction,
A plurality of side walls corresponding to each side of the polygon,
A plurality of corners corresponding to each vertex of the polygon,
The plurality of corners,
Windward corners arranged on the windward side of the wind,
A leeward corner arranged on the leeward side of the wind,
And a corner cut corner of the corner excluding the leeward corner and the leeward corner in the height direction of the building.

また、本発明の一実施形態に係る建物は、
前記側壁部及び前記角部に対して前記建物の外周方向に沿って凸状に延設された複数の整風部を備え、
前記複数の整風部は、前記建物の高さ方向に所定の間隔で並設された、ことを特徴とする。 Also, the building according to one embodiment of the present invention,
The air conditioner further includes a plurality of air conditioners extended in a convex shape along the outer peripheral direction of the building with respect to the side wall and the corner,
The plurality of air conditioners are arranged side by side at predetermined intervals in a height direction of the building.

また、本発明の一実施形態に係る建物は、
前記角部に延設された前記整風部の前記角部に対する段差は、前記側壁部に延設された前記整風部の前記側壁部に対する段差よりも大きい、ことを特徴とする。 Also, the building according to one embodiment of the present invention,
The step of the air conditioner extending from the corner to the corner may be larger than the step of the air adjuster extending to the side wall from the side wall.

また、本発明の一実施形態に係る建物は、
前記整風部は、前記建物の外周方向に垂直な断面形状として、方形状の断面形状を有する、ことを特徴とする。 Also, the building according to one embodiment of the present invention,
The air conditioner has a rectangular cross-sectional shape as a cross-sectional shape perpendicular to the outer peripheral direction of the building.

また、本発明の一実施形態に係る建物は、
前記整風部は、前記整風部の下面に形成された水切り部を備える、ことを特徴とする。 Also, the building according to one embodiment of the present invention,
The air conditioner may include a drainer formed on a lower surface of the air conditioner.

本発明の一実施形態に係る建物によれば、複数の角部は、風上側角部と、風下側角部と、風上側角部及び風下側角部を除く角部に対して建物の高さ方向に隅切りした隅切り角部と、を含む。そのため、建物が、所定の方向から風を受けると、その風は、風上側角部によって２方向の風に分流され、その分流された風が、側壁部に沿って隅切り角部及び風下側角部の順にそれぞれ通過して、建物１の風下側で合流する。このとき、隅切り角部は、建物の高さ方向に隅切りされているため、風が隅切り角部から乖離しにくくなるので、風が隅切り角部を通過するときの空気抵抗が低減される。また、建物が上記のような複数の角部を備えるようにするために、建物の居室空間や建築構造が大きく制限されることもない。したがって、建物は、居室空間や建築構造を大きく制限することなく、上記のような複数の角部を備えることで、建物が平面視において流線形の形状とみなすことができるので、居室空間や建築構造に対する制限を緩和し、風の道を確保するとともに、風環境を改善することができる。   According to the building according to the embodiment of the present invention, the plurality of corners includes a leeward corner, a leeward corner, and a height of the building with respect to the corners excluding the leeward corner and the leeward corner. And a corner cut corner cut in the vertical direction. Therefore, when the building receives wind from a predetermined direction, the wind is split into wind in two directions by the windward corner, and the split wind is divided along the side wall into the corner cut corner and the leeward side. Each of them passes in the order of the corners and merges on the leeward side of the building 1. At this time, since the corners are cut in the height direction of the building, it is difficult for the wind to separate from the corners, so that the air resistance when the wind passes through the corners is reduced. Is done. Further, since the building is provided with the plurality of corners as described above, the living room space and the building structure of the building are not greatly limited. Therefore, the building can be regarded as a streamlined shape in a plan view by providing the plurality of corners as described above without greatly restricting the living room space and the architectural structure. It can ease the restrictions on the structure, secure the wind path, and improve the wind environment.

以下、本発明を実施するための形態について添付図面を参照しつつ説明する。   Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

（第１の実施の形態）
図１は、本発明の第１の実施の形態に係る建物１を示す斜視図である。図２は、本発明の第１の実施の形態に係る建物１を示す縦断面図である。図３は、本発明の第１の実施の形態に係る建物１を示すＡ−Ａ線断面図である。 (First Embodiment)
FIG. 1 is a perspective view showing a building 1 according to the first embodiment of the present invention. FIG. 2 is a longitudinal sectional view showing the building 1 according to the first embodiment of the present invention. FIG. 3 is a sectional view taken along line AA of the building 1 according to the first embodiment of the present invention.

建物１は、複数の階層を有する多層階の建物であって、例えば、タワーマンション等の集合住宅、オフィスビル、ホテル、商業施設ビル等の用途で使用される。また、建物１は、例えば、鉄筋コンクリート造、鉄骨造や、鉄骨鉄筋コンクリート造、プレキャストコンクリート造等の建築構造が採用される。   The building 1 is a multi-story building having a plurality of floors, and is used for applications such as an apartment house such as a tower apartment, an office building, a hotel, and a commercial facility building. The building 1 employs a building structure such as a reinforced concrete structure, a steel frame structure, a steel frame reinforced concrete structure, a precast concrete structure, or the like.

建物１は、所定の方向から風Ｗを受ける。「所定の方向」とは、建物１が建築される敷地において、風Ｗが吹く時間帯が長い又は頻度が高い風向、すなわち、主風向を示すものである。例えば、建物１が、南側に海が位置する海岸沿いの敷地に建築されている場合には、建物１は、海から吹き寄せる南風を受ける時間帯が長い又は頻度が高いことから、所定の方向としては、「南」が相当する。このとき、建物１は、所定の方向として南から風Ｗを受けるものであるが、南以外の方向から風を全く受けないことを示すものではない。   The building 1 receives the wind W from a predetermined direction. The “predetermined direction” indicates a wind direction in which the wind W blows over a long or high frequency on the site where the building 1 is constructed, that is, the main wind direction. For example, when the building 1 is constructed on a site along the coast where the sea is located on the south side, the building 1 receives a south wind blowing from the sea for a long time period or has a high frequency. The direction corresponds to "South". At this time, the building 1 receives the wind W from the south as a predetermined direction, but does not indicate that the building 1 does not receive the wind at all from directions other than the south.

建物１は、平面視において多角形の外形を有し、多角形の各辺に対応する複数の側壁部２と、角形の各頂点に対応する複数の角部３と、側壁部２の内部を各階に仕切る複数の床部４と、を備える。   The building 1 has a polygonal outer shape in plan view, and includes a plurality of side walls 2 corresponding to each side of the polygon, a plurality of corners 3 corresponding to each vertex of the polygon, and the inside of the side wall 2. A plurality of floors 4 for partitioning each floor.

なお、図１は、建物１の外形の形状を示すものであり、その他の構成要素（例えば、窓、バルコニー等）の詳細は省略している。また、図２及び図３では、側壁部２、角部３及び床部４の断面を示すものであり、その他の構成要素（例えば、窓、バルコニー、鉄骨、鉄筋、間仕切壁、柱、梁、階段、エレベータ等）の詳細は省略している。   FIG. 1 shows the outer shape of the building 1, and details of other components (for example, windows, balconies, etc.) are omitted. 2 and 3 show cross sections of the side wall portion 2, the corner portion 3, and the floor portion 4, and include other components (for example, windows, balconies, steel frames, reinforcing bars, partition walls, columns, beams, and the like). Details of stairs, elevators, etc.) are omitted.

側壁部２及び角部３は、例えば、コンクリート壁や、ＡＬＣ板、タイル等の外壁材で構成されている。   The side wall 2 and the corner 3 are made of, for example, an outer wall material such as a concrete wall, an ALC plate, or a tile.

複数の角部３は、風Ｗの風上側に配置された風上側角部３０と、風Ｗの風下側に配置された風下側角部３１と、風上側角部３０及び風下側角部３１を除く角部３に対して建物１の高さ方向に隅切りした隅切り角部３２Ａ、３２Ｂと、を含む。   The plurality of corners 3 include a leeward corner 30 disposed on the leeward side of the wind W, a leeward side corner 31 disposed on the leeward side of the wind W, and a leeward side corner 30 and a leeward side corner 31. Corners 32A and 32B which are cut in the height direction of the building 1 with respect to the corners 3 excluding the corners 3A and 3B.

ここで、「多角形」とは、すべての内角が１８０度未満である凸多角形である。本実施の形態では、多角形の一例として、正方形の場合について説明する。したがって、側壁部２は、正方形の４辺に対応するものである。また、複数の角部３は、正方形の４つの各頂点に対応するものであるから、建物１は、４つの角部３を備え、４つの角部３は、風上側角部３０と、風下側角部３１と、２つの隅切り角部３２Ａ、３２Ｂと、を含む。   Here, the “polygon” is a convex polygon having all interior angles of less than 180 degrees. In the present embodiment, a case of a square will be described as an example of a polygon. Therefore, the side walls 2 correspond to the four sides of the square. Further, since the plurality of corners 3 correspond to the four vertices of the square, the building 1 includes four corners 3, and the four corners 3 are the leeward corner 30 and the leeward. A side corner portion 31 and two corner cut corner portions 32A and 32B are included.

隅切り角部３２Ａ、３２Ｂは、直角二等辺三角形の形状で隅切りしたものである。なお、隅切り角部３２Ａ、３２Ｂは、直角部分を挟む二辺の長さが異なる直角三角形の形状で隅切りしてもよい。   The corner cut corners 32A and 32B are cut in the shape of a right-angled isosceles triangle. Note that the corner cut corners 32A and 32B may be cut in the shape of a right triangle having two sides sandwiching the right angle portion and having different lengths.

また、建物１は、側壁部２及び角部３に対して建物１の外周方向に沿って凸状に延設された複数の整風部５を備える。複数の整風部５は、建物１の高さ方向に所定の間隔Ｈ１で並設される。   Further, the building 1 includes a plurality of air conditioning units 5 protruding from the side walls 2 and the corners 3 along the outer peripheral direction of the building 1. The plurality of air conditioners 5 are arranged side by side at a predetermined interval H1 in the height direction of the building 1.

本実施の形態では、複数の整風部５は、図１及び図２に示すように、各階に１つずつ設けられおり、所定の間隔Ｈ１として、階高に相当する間隔で並設される。なお、各階に複数の整風部５を設けてもよいし、複数階に１つの整風部５を設けてもよい。また、建物１の高さ方向に応じて、所定の間隔Ｈ１を変化させてもよく、高層階における間隔を、低層階における間隔よりも広くしてもよいし、その反対に狭くしてもよい。   In the present embodiment, as shown in FIGS. 1 and 2, the plurality of air conditioners 5 are provided one by one on each floor, and are arranged side by side at predetermined intervals H1 at intervals corresponding to the floor height. Note that a plurality of air conditioning units 5 may be provided on each floor, or one air conditioning unit 5 may be provided on a plurality of floors. Further, the predetermined interval H1 may be changed according to the height direction of the building 1, and the interval on the higher floor may be wider than the interval on the lower floor, or may be narrower on the contrary. .

整風部５は、建物１の外周方向に沿って凸状に延設されており、その凸状部分は、側壁部２に対して段差をなすものである。本実施の形態では、図３に示すように、角部３に延設された整風部５の角部３に対する段差Ｌ１は、側壁部２に延設された整風部５の側壁部２に対する段差Ｌ２と等しくなっている。したがって、整風部５は、凸状部分の段差が建物１の外周方向に沿って一定（（Ｌ１＝Ｌ２））になるように、延設されている。   The air conditioner 5 extends in a convex shape along the outer peripheral direction of the building 1, and the convex portion forms a step with respect to the side wall 2. In the present embodiment, as shown in FIG. 3, the step L1 of the wind regulating unit 5 extending to the corner 3 with respect to the corner 3 is the step of the wind regulating unit 5 extending to the side wall 2 with respect to the side wall 2. It is equal to L2. Therefore, the air conditioning section 5 is extended so that the step of the convex portion is constant ((L1 = L2)) along the outer peripheral direction of the building 1.

本実施の形態では、整風部５の段差Ｌ１、Ｌ２は、例えば、１００ｍｍとし、高さＨ２は、例えば、１００ｍｍとしたが、これらの寸法は適宜変更してもよい。また、建物１の高さ方向に応じて、整風部５の段差Ｌ１、Ｌ２及び高さＨ２を変化させてもよく、高層階における整風部５の段差Ｌ１、Ｌ２及び高さＨ２を、低層階における整風部５の段差Ｌ１、Ｌ２及び高さＨ２よりも大きくしてもよいし、その反対に小さくしてもよい。   In the present embodiment, the steps L1 and L2 of the air conditioner 5 are set to, for example, 100 mm, and the height H2 is set to, for example, 100 mm. However, these dimensions may be appropriately changed. Further, the steps L1, L2 and the height H2 of the wind rectification unit 5 may be changed according to the height direction of the building 1, and the steps L1, L2 and the height H2 of the wind rectification unit 5 on the high floor are changed to the low floor. May be larger than the steps L1, L2 and the height H2 of the air conditioner 5, or may be smaller on the contrary.

整風部５は、側壁部２及び角部３を構成するコンクリート壁や外壁材に一体的に形成されている。なお、整風部５は、側壁部２及び角部３とは別体の部材で形成し、側壁部２及び角部３に取り付けるようにしてもよい。   The air conditioner 5 is formed integrally with a concrete wall or an outer wall material constituting the side wall 2 and the corner 3. The air conditioner 5 may be formed as a member separate from the side wall 2 and the corner 3, and may be attached to the side wall 2 and the corner 3.

It has a rectangular cross-sectional shape. That is, the air conditioner 5 includes the upper surface 50, the side surface 51, and the lower surface 52 that form a convex shape. The upper surface 50 and the lower surface 52 are arranged in a horizontal direction, and the side surface 51 is arranged in a vertical direction (height direction). You. Further, the air conditioner 5 includes a drainer 53 formed on the lower surface 52.

整風部５は、方形状の断面形状に代えて、図４（ｂ）、（ｃ）及ぶ（ｄ）に示すように、台形状の断面形状を有するものでもよい。   The air conditioner 5 may have a trapezoidal cross-sectional shape, as shown in FIGS. 4B, 4C, and 4D, instead of the rectangular cross-sectional shape.

図４（ｂ）に示す第２の実施例の整風部５では、上面５０が水平方向に配置され、下面５２が水平方向に対して側壁部２から離れるほど上方に向かう斜め上方向に配置され、側面５１が鉛直方向に配置される。   In the air conditioning section 5 of the second embodiment shown in FIG. 4B, the upper surface 50 is arranged in the horizontal direction, and the lower surface 52 is arranged in an obliquely upward direction as the distance from the side wall 2 increases with respect to the horizontal direction. , The side surface 51 is arranged in the vertical direction.

The farther away from the side wall portion 2, the upper side is disposed obliquely upward and the side surface 51 is disposed in the vertical direction.

なお、整風部５の断面形状は、上記実施例に限定されず、側面５１を鉛直方向に対して斜め方向に配置してもよいし、上面５０、側面５１及び下面５２の少なくともいずれか一面を曲線状に配置してもよい。   The cross-sectional shape of the air conditioner 5 is not limited to the above embodiment, and the side surface 51 may be arranged obliquely to the vertical direction, or at least one of the upper surface 50, the side surface 51, and the lower surface 52 may be formed. They may be arranged in a curved shape.

（シミュレーションによる評価）
次に、建物１の性能を評価するためにシミュレーションを行った。以下、シミュレーションの条件及び結果について説明する。 (Evaluation by simulation)
Next, a simulation was performed to evaluate the performance of the building 1. Hereinafter, conditions and results of the simulation will be described.

評価対象となる建物１は、外形が４４．２ｍ×３４．４ｍの長方形、高さが１１７．６５ｍであり、地上３２階建てで３１個の整風部５を各階に１つずつ並設するものとした。また、風の流入条件としては、地上４４ｍで５．１ｍ／ｓをべき乗則（地表面粗度区分ＩＶ）により、地上５０ｍ高さの風速に換算するものとした。   The building 1 to be evaluated has a rectangular shape of 44.2 mx 34.4 m, a height of 117.65 m, and has 32 floors above the ground and 31 air conditioning units 5 arranged side by side on each floor. And The wind inflow conditions were such that 5.1 m / s at 44 m above the ground was converted to a wind speed at a height of 50 m above the ground by a power law (ground surface roughness classification IV).

また、評価方法としては、建物１の風下側に位置する後背地評価エリアを、幅が敷地幅の１倍、奥行きが建物１の高さの２倍のエリアとしたときに、当該後背地評価エリアの面積に対して、風速が１．５ｍ／ｓ以上となるエリアの面積の比率（％）を計算することにより評価した。   In addition, as an evaluation method, when the hinterland evaluation area located on the leeward side of the building 1 is an area having a width of 1 times the site width and a depth of twice the height of the building 1, the hinterland evaluation area is used. Evaluation was made by calculating the ratio (%) of the area of the area where the wind speed was 1.5 m / s or more to the area of the area.

（第２の実施の形態）
第１の実施の形態では、図３に示すように、整風部５の凸状部分の段差が、側壁部２及び角部３に対して建物１の外周方向に沿って一定（Ｌ１＝Ｌ２）であるものとして説明したが、第２の実施の形態では、整風部５の凸状部分の段差が、側壁部２と角部３との間で異なるものとした。第２の実施の形態のその他の構成は、第１の実施の形態と同様としたため、説明を省略する。 (Second embodiment)
In the first embodiment, as shown in FIG. 3, the step of the convex portion of the air conditioner 5 is constant along the outer peripheral direction of the building 1 with respect to the side wall 2 and the corner 3 (L1 = L2). However, in the second embodiment, the step of the convex portion of the air conditioner 5 is different between the side wall 2 and the corner 3. The other configuration of the second embodiment is the same as that of the first embodiment, and the description is omitted.

図５は、本発明の第２の実施の形態に係る建物１を示し、（ａ）は第１の実施例、（ｂ）は第２の実施例を示すＡ−Ａ線断面図である。   5A and 5B show a building 1 according to a second embodiment of the present invention, wherein FIG. 5A is a cross-sectional view taken along line AA of the first embodiment, and FIG.

図５（ａ）に示す第１の実施例では、２つの隅切り角部３２Ａ、３２Ｂに延設された整風部５の２つの隅切り角部３２Ａ、３２Ｂに対する段差Ｌ３は、側壁部２に延設された整風部５の側壁部２に対する段差Ｌ５よりも大きくなっている。また、風上側角部３０及び風下側角部３１に延設された整風部５の風上側角部３０及び風下側角部３１に対する段差Ｌ４は、側壁部２に延設された整風部５の側壁部２に対する段差Ｌ５よりも大きくなっている。   In the first embodiment shown in FIG. 5A, a step L3 with respect to the two corner cut corners 32A, 32B of the air conditioning unit 5 extending to the two corner cut corners 32A, 32B is formed on the side wall 2. The level difference is larger than the step L5 with respect to the side wall 2 of the extended air conditioning unit 5. In addition, a step L4 between the windward side corner 30 and the leeward side corner 31 of the windward side extending from the windward side corner 30 and the leeward side corner 31 is different from that of the windward side 5 extending along the side wall 2. It is larger than the step L5 with respect to the side wall portion 2.

本実施の形態では、整風部５の２つの隅切り角部３２Ａ、３２Ｂに対する段差Ｌ３、及び、整風部５の風上側角部３０及び風下側角部３１に対する段差Ｌ４は、例えば、５００ｍｍとし、整風部５の側壁部２に対する段差Ｌ５は、例えば、１００ｍｍとしたが、これらの寸法は適宜変更してもよい。また、段差Ｌ３と段差Ｌ４の寸法を異なるようにしてもよい。   In the present embodiment, the level difference L3 between the two corner cutting corners 32A and 32B of the wind regulating unit 5 and the level difference L4 between the windward corner 30 and the leeward corner 31 of the wind regulating unit 5 are, for example, 500 mm. The level difference L5 of the air conditioner 5 with respect to the side wall 2 is, for example, 100 mm, but these dimensions may be changed as appropriate. Further, the dimensions of the step L3 and the step L4 may be different.

なお、本実施の形態に係る建物１の角部３は、整風部５の段差Ｌ３及び段差Ｌ４を段差Ｌ５よりも大きくするために、第１の実施の形態に係る建物１の角部３に比べて、建物１の内側に切り欠くように形成されているが、角部３を建物１の内側に切り欠くように形成することに代えて、整風部５の凸状部分を建物１の外側に張り出すように形成してもよい。   In addition, the corner 3 of the building 1 according to the first embodiment is provided at the corner 3 of the building 1 according to the first embodiment in order to make the steps L3 and L4 of the air conditioning unit 5 larger than the step L5. In comparison, although it is formed so as to be cut out inside the building 1, instead of forming the corner portion 3 so as to be cut out inside the building 1, the convex portion of the air conditioning unit 5 is formed outside the building 1. It may be formed so as to overhang.

図５（ｂ）に示す第２の実施例の整風部５では、２つの隅切り角部３２Ａ、３２Ｂは、曲線状に隅切りしたものである。そして、整風部５は、２つの隅切り角部３２Ａ、３２Ｂの曲線状の外形形状に沿って曲線状に延設されている。   In the air conditioner 5 of the second embodiment shown in FIG. 5B, the two corner cut corners 32A and 32B are cut in a curved shape. The air conditioning unit 5 extends in a curved shape along the curved outer shape of the two corner cut corners 32A and 32B.

また、２つの隅切り角部３２Ａ、３２Ｂに延設された整風部５の２つの隅切り角部３２Ａ、３２Ｂに対する段差Ｌ６は、側壁部２に延設された整風部５の側壁部２に対する段差Ｌ７よりも大きくなっている。本実施の形態では、整風部５の２つの隅切り角部３２Ａ、３２Ｂに対する段差Ｌ６は、例えば、５００ｍｍとし、整風部５の側壁部２に対する段差Ｌ７は、例えば、１００ｍｍとしたが、これらの寸法は適宜変更してもよい。   In addition, the step L6 of the wind regulating section 5 extending to the two corner cutting corners 32A and 32B with respect to the two corner cutting corners 32A and 32B is different from the side wall 2 of the wind regulating section 5 extending to the side wall 2. It is larger than the step L7. In the present embodiment, the level difference L6 between the two corner cut corners 32A and 32B of the air conditioner 5 is, for example, 500 mm, and the level difference L7 between the side wall 2 of the air conditioner 5 is, for example, 100 mm. The dimensions may be changed as appropriate.

以上のように、第１及び第２の実施の形態に係る建物１によれば、複数の角部３は、風上側角部３０と、風下側角部３１と、風上側角部３０及び風下側角部３１を除く角部３に対して建物１の高さ方向に隅切りした隅切り角部３２Ａ、３２Ｂと、を含む。   As described above, according to the building 1 according to the first and second embodiments, the plurality of corners 3 include the leeward corner 30, the leeward corner 31, the leeward corner 30, and the leeward. The corners 3 excluding the side corners 31 include corner cut corners 32A and 32B that are cut in the height direction of the building 1 with respect to the corners 3.

そのため、建物１が、所定の方向から風Ｗを受けると、その風Ｗは、風上側角部３０によって２方向の風Ｗａ、Ｗｂに分流され、その分流された風Ｗａ、Ｗｂが、側壁部２に沿って隅切り角部３２Ａ、３２Ｂ、風下側角部３１の順にそれぞれ通過して、建物１の風下側で合流し、風Ｗｃとなる。このとき、隅切り角部３２Ａ、３２Ｂは、建物１の高さ方向に隅切りされているため、風Ｗａ、Ｗｂが隅切り角部３２Ａ、３２Ｂから乖離しにくくなり、風Ｗａ、Ｗｂが隅切り角部３２Ａ、３２Ｂを通過するときの空気抵抗が低減される。また、建物１が上記のような複数の角部３を備えるようにするために、建物１の居室空間や建築構造が大きく制限されることもない。   Therefore, when the building 1 receives the wind W from a predetermined direction, the wind W is split by the windward corner 30 into winds Wa and Wb in two directions, and the split winds Wa and Wb are separated from the side wall portion. 2, the corners 32 </ b> A and 32 </ b> B and the leeward corner 31 respectively pass in this order, and merge on the leeward side of the building 1 to form the wind Wc. At this time, since the corners 32A and 32B are cut in the height direction of the building 1, the winds Wa and Wb are unlikely to separate from the corners 32A and 32B, and the winds Wa and Wb are cornered. The air resistance when passing through the cut corners 32A and 32B is reduced. In addition, since the building 1 includes the plurality of corners 3 as described above, the living room space and the building structure of the building 1 are not greatly limited.

したがって、建物１は、居室空間や建築構造を大きく制限することなく、上記のような複数の角部３を備えることで、建物１が平面視において流線形の形状とみなすことができるので、居室空間や建築構造に対する制限を緩和し、風の道を確保するとともに、風環境を改善することができる。   Therefore, the building 1 can be regarded as having a streamlined shape in plan view by providing the plurality of corners 3 as described above without greatly limiting the living room space and the architectural structure. Relaxing restrictions on space and architectural structures, securing wind paths and improving the wind environment.

また、第１及び第２の実施の形態に係る建物１によれば、複数の整風部５は、側壁部２及び角部３に対して建物１の外周方向に沿って凸状に延設されており、建物１の高さ方向に所定の間隔で並設されたものである。そのため、建物１の高さ方向に隣接する整風部５が、風Ｗの流れを誘導する誘導手段となるとともに、建物１の高さ方向に隣接する整風部５の中間部分が、風Ｗの流路となるので、風Ｗが、風上側から風下側に向けて建物１の外周方向に沿うように、すなわち、水平方向に流れることになる。したがって、建物１は、居室空間や建築構造を大きく制限することなく、上記のような複数の整風部５を備えることで、風Ｗが風上側から風下側に向けて水平方向に流れることにより、側壁部２に沿って吹き降ろしの風が発生することを抑制することができるので、居室空間や建築構造に対する制限を緩和し、風の道を確保するとともに、風環境を改善することができる。   Further, according to the building 1 according to the first and second embodiments, the plurality of air conditioners 5 are extended in a convex shape along the outer peripheral direction of the building 1 with respect to the side wall 2 and the corner 3. They are arranged side by side at predetermined intervals in the height direction of the building 1. Therefore, the wind rectification unit 5 adjacent to the building 1 in the height direction serves as a guiding unit for guiding the flow of the wind W, and an intermediate portion of the wind rectification unit 5 adjacent to the building 1 in the height direction serves as the flow of the wind W. Since it is a road, the wind W flows from the windward side to the leeward side along the outer circumferential direction of the building 1, that is, flows in the horizontal direction. Therefore, the building 1 is provided with the plurality of air conditioning units 5 as described above without greatly restricting the living room space and the building structure, so that the wind W flows in the horizontal direction from the windward side to the leeward side, Since it is possible to suppress the generation of the wind that blows down along the side wall portion 2, it is possible to relax restrictions on the living room space and the architectural structure, secure a wind path, and improve the wind environment.

また、第２の実施の形態に係る建物１によれば、角部３に延設された整風部５の角部３に対する段差は、側壁部２に延設された整風部５の側壁部２に対する段差よりも大きい。そのため、角部３において、風Ｗが水平方向により流れるように誘導されるので、居室空間や建築構造に対する制限を緩和し、風の道を確保するとともに、風環境を改善することができる。   Further, according to the building 1 according to the second embodiment, the step of the wind regulating part 5 extended to the corner 3 with respect to the corner 3 is different from that of the sidewall 2 of the wind regulating part 5 extended to the side wall 2. Is larger than the step height. For this reason, since the wind W is guided to flow in the horizontal direction in the corner portion 3, restrictions on the living room space and the building structure can be relaxed, a wind path can be secured, and the wind environment can be improved.

また、第１及び第２の実施の形態に係る建物１によれば、整風部５は、建物１の外周方向に垂直な断面形状として、方形状の断面形状を有する。そのため、整風部５を簡易な方法で形成することができるので、建物１の建築コストの上昇を抑制することができる。   Further, according to the buildings 1 according to the first and second embodiments, the air conditioner 5 has a rectangular cross-sectional shape as a cross-sectional shape perpendicular to the outer peripheral direction of the building 1. For this reason, the air conditioner 5 can be formed by a simple method, so that an increase in the construction cost of the building 1 can be suppressed.

また、第１及び第２の実施の形態に係る建物１によれば、整風部５は、整風部５の下面５２に水切り部５３を備える。そのため、水切り部５３により整風部５に付着した雨水の雨だれが抑制されるので、側壁部２及び角部３の汚れを防止することができる。   Further, according to the buildings 1 according to the first and second embodiments, the air conditioner 5 includes the drainer 53 on the lower surface 52 of the air conditioner 5. For this reason, since the dripping part 53 suppresses the dripping of the rainwater attached to the wind regulating part 5, it is possible to prevent the side wall part 2 and the corner part 3 from being stained.

以上、本発明の第１及び第２の実施の形態について説明したが、本発明は上記の実施の形態に限定されるものではなく、本発明の技術的思想を逸脱しない範囲で適宜変更可能である。   Although the first and second embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the technical idea of the present invention. is there.
