本発明は、多数階を備えた建物本体の屋上に、庭園と、展望部とを設けてある建物に関する。   The present invention relates to a building in which a garden and an observation section are provided on the roof of a building body having a plurality of floors.

従来、この種の建物としては、建物本体の最上階をトラス構造とガラス外壁とを組み合わせた吹抜構造とし、その内側に、展望部となる廊下を設けたもの（以後、単に第１従来例という）があった。この第１従来例は、前記廊下において、建物本体の外方の景色を観賞できる視線と、建物本体内の吹抜空間の下方を観賞できる視線とを確保できるように構成されている。また、庭園は、前記廊下を設けてある平面位置とは隔たった建物本体の屋上部分に設けられており、庭園と展望部とにおける景色の観賞は、それぞれ個別に行われるもので、無関係なものであった。
また、別の例としては、並設された２棟の高層建物の最上階にわたる状態に展望部となるフロア構造体を架設したもの（以後、単に第２従来例という）があった（例えば、特許文献１参照）。この第２従来例は、前記フロア構造体において、建物本体の外方の景色を観賞できる視線と、フロア構造体の直下（２棟の高層建物の一階部分につながる庭園）の景色を見下ろせる視線とを確保できるように構成されている。 Conventionally, as this type of building, the top floor of the building body has a blown-out structure combining a truss structure and a glass outer wall, and a corridor serving as an observation section is provided inside thereof (hereinafter simply referred to as the first conventional example). )was there. The first conventional example is configured so as to ensure a line of sight in which the scenery outside the building body can be viewed and a line of sight in the lower part of the atrium space in the building body can be secured in the hallway. In addition, the garden is provided on the roof of the building body separated from the planar position where the corridor is provided, and the viewing of the scenery in the garden and the observation section is performed individually and is irrelevant. Met.
In addition, as another example, there was a structure (hereinafter simply referred to as a second conventional example) in which a floor structure serving as an observation part is installed in a state extending over the top floor of two high-rise buildings arranged side by side (for example, Patent Document 1). In the second conventional example, in the floor structure, a view line that allows viewing of the scenery outside the building body and a view directly under the floor structure (a garden connected to the first floor of two high-rise buildings) can be looked down on. It is comprised so that a gaze can be ensured.

以下に本発明の実施の形態を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１〜３は、本発明の建物の一実施形態である高層ビルＢの屋上を示すものである。
高層ビルＢは、多数階層を備えた建物本体１の屋上に、庭園２と、展望部３とを設けて構成してある。 1-3 show the rooftop of the high-rise building B which is one Embodiment of the building of this invention.
The high-rise building B is configured by providing a garden 2 and an observation section 3 on the roof of a building body 1 having a number of levels.

屋上には、前記庭園２や展望部３の他にも、エレベータやパイプスペースや階段室等を備えた塔屋部４、ステージと傾斜階段を備えたイベント部５が設けられている（図１、図２参照）。   In addition to the garden 2 and the observation section 3, the roof has a tower section 4 with an elevator, a pipe space, a staircase, etc., and an event section 5 with a stage and an inclined staircase (FIG. 1, (See FIG. 2).

屋上での平面配置は、図２に示すように、一端側に塔屋部４、中央部分に前記イベント部５、残りのスペースが庭園２として構成されている。
また、前記展望部３は、前記庭園２と同一階層に形成された第１展望部３Ａと、前記庭園２の上方に離間する空中に形成された第２展望部３Ｂとを備えて構成してある。 As shown in FIG. 2, the flat layout on the rooftop is configured as a tower 4 at one end, the event 5 at the center, and the garden 2 as the remaining space.
The observing unit 3 includes a first observing unit 3A formed on the same level as the garden 2 and a second observing unit 3B formed in the air spaced above the garden 2. is there.

前記第１展望部３Ａは、庭園２を同じ目線で観賞できるように構成されており、具体的には、屋上の庭園２部全てが第１展望部３Ａに該当する。
従って、この第１展望部３Ａからは、図３に示すように、前記庭園２を観賞できる視線Ｌ１ａと、建物本体１の外方の景色を観賞できる視線Ｌ１ｂとを確保できる。
前記第２展望部３Ｂは、庭園２を見下ろす状態で観賞できるように構成されており、具体的には、屋上の上方に離間して回廊状に形成してあり、建物平面のほぼ外周部に沿って、前記庭園２を囲繞する状態に形成してある。第２展望部３Ｂは、屋上に立設した複数の細い柱６で支持されている。
従って、この第２展望部３Ｂからは、前記庭園２を観賞できる視線Ｌ２ａと、建物本体１の外方の景色を観賞できる視線Ｌ２ｂと、前記建物本体１の外方の景色を前記庭園２の借景として観賞できる視線Ｌ２ｃと、平面視において前記庭園２を挟んで見通せる位置に配置された第２展望部３Ｂの別の個所を見る視線Ｌ２ｄとを確保できる。 The first viewing section 3A is configured so that the garden 2 can be viewed from the same line of sight. Specifically, the entire rooftop garden 2 section corresponds to the first viewing section 3A.
Therefore, as shown in FIG. 3, a line of sight L1a for viewing the garden 2 and a line of sight L1b for viewing the scenery outside the building body 1 can be secured from the first viewing section 3A.
The second observing part 3B is configured so that it can be viewed while looking down at the garden 2. Specifically, the second observing part 3B is formed in a gallery-like shape spaced apart above the rooftop, and is almost at the outer periphery of the building plane. The garden 2 is formed so as to surround the garden. The 2nd observation part 3B is supported by the some thin pillar 6 standingly arranged on the rooftop.
Therefore, from the second observing section 3B, a line of sight L2a for viewing the garden 2, a line of sight L2b for viewing the scenery outside the building body 1, and the scenery outside the building body 1 are displayed in the garden 2. It is possible to secure a line of sight L2c that can be viewed as a borrowed view and a line of sight L2d that sees another part of the second viewing portion 3B that is disposed in a position that can be seen through the garden 2 in plan view.

前記庭園２は、例えば、芝生や木々が植栽されている。また、木々に関しては、その高さは大小各種用意されている。特に、高木に関しては、前記第２展望部３Ｂの床高さより高い木々も植えられている（図１、図２参照）。
また、屋上の外周部には、透明ガラスで形成された防風スクリーン７が全周にわたって設置されている。防風スクリーン７は、屋上の上面から、塔屋部４の上端までの高さ範囲にわたって設けられている。そして、第２展望部３Ｂの内周側にも、透明ガラスの内周壁８が設置されている。
防風スクリーン７を設けてあることで、高層ビルの上空で、風が強く吹く時であっても、庭園２やイベント部５への風当たりを和らげることができる。
また、内周壁８を設けてあることで、前記第２展望部３Ｂそのものを外気と遮断することができ、空調の効いた空間を形成することができる。 In the garden 2, for example, lawns and trees are planted. In addition, with regard to trees, various heights are available. In particular, regarding the high trees, trees higher than the floor height of the second observation part 3B are also planted (see FIGS. 1 and 2).
In addition, a windproof screen 7 made of transparent glass is installed on the entire outer periphery of the rooftop. The windscreen 7 is provided over a range of height from the upper surface of the roof to the upper end of the tower 4. And the inner peripheral wall 8 of a transparent glass is installed also in the inner peripheral side of the 2nd observation part 3B.
By providing the windscreen 7, it is possible to relieve the wind hitting the garden 2 and the event unit 5 even when the wind blows strongly above a high-rise building.
Further, since the inner peripheral wall 8 is provided, the second observing portion 3B itself can be shut off from the outside air, and an air-conditioned space can be formed.

本実施形態の建物によれば、通常の屋上からの視線Ｌ１ｂ，Ｌ２ｂ、及び、庭園を観賞する視線Ｌ１ａ，Ｌ２ａを確保して景色を楽しめることに加えて、第２展望部３Ｂそのものが庭園２の上方に離間する空中に形成されていることによって、眼下に位置する庭園２を見る視線Ｌ２ａと、建物本体１の外方の景色を見る視線Ｌ２ｂとが重なり、前述の視線Ｌ２ｃによって借景を実感することができる。その結果、庭園２の景色が、建物本体１の外方の景色を背景として高い位置に浮いているかの如く観賞することができる。
また、その様な、現実離れした景色を観賞することによって、自らが居る場所そのものの浮游感をも感じることができ、あたかも、異次元空間に身を置いているかの視覚効果を楽しむことができる。
即ち、所謂「借景」の考え方を、屋上庭園の観賞においても、より効果的に取り入れることができ、ただ高い位置での眺望を観賞できるだけの視覚効果や、庭園の美しさのみを観賞できる視覚効果にとどまらず、それらの何れもが融合した独特の視覚効果をも楽しむことができるようになる。
更には、平面視において庭園２を挟んで見通せる位置に配置された第２展望部３Ｂの別の個所を見る視線Ｌ２ｄを確保できることによって、一方の第２展望部個所からの視界に、他方の第２展望部個所や、そこで景色を観賞している他の人の姿が入り、第２展望部３Ｂの浮游感をより実感することができ、自らの居る場所そのものの浮游感を、よりリアルに感じることができる。
また、回廊状の第２展望部３Ｂを設けてあることで、庭園２を、全周にわたってどの位置からも観賞することができ、より変化に富んだ視覚効果を楽しむことができる。
更には、庭園に高木を植栽するような場合、庭園を囲繞する第２展望部によって高木の側方を全周にわたって拘束することができる。その結果、高木が転倒したり、屋上から転落するといったことを防止し易い。
また、前記防風スクリーン７によって、庭園２への風当たりを緩和することが可能となる。
従って、庭園２に植栽する植物への風害を防止できると共に、庭園２を観賞する環境を向上させることができる。 According to the building of the present embodiment, in addition to ensuring the line of sight L1b, L2b from the normal rooftop and the lines of sight L1a, L2a for viewing the garden and enjoying the scenery, the second observation section 3B itself is the garden 2 Since the line of sight L2a looking at the garden 2 located below the eye and the line of sight L2b looking at the scenery outside the building body 1 overlap with each other, the above-mentioned line of sight L2c realizes the borrowed scenery. can do. As a result, the scenery of the garden 2 can be viewed as if it is floating at a high position with the scenery outside the building body 1 as the background.
Also, by viewing such unrealistic scenery, you can feel the floating feeling of the place where you are, and enjoy the visual effect as if you are in a different dimensional space.
In other words, the so-called “rental scenery” concept can be incorporated more effectively in the viewing of the rooftop garden, and the visual effect that only allows you to appreciate the view at a high position or the beauty of the garden. In addition to this, you will be able to enjoy the unique visual effects that fuse all of them.
Furthermore, by securing a line of sight L2d for viewing another part of the second observing part 3B arranged in a position that can be seen through the garden 2 in plan view, the field of view from one second observing part has a second view. 2 The observatory part and the appearance of other people who appreciate the scenery enter, and you can feel the floating feeling of the second observing part 3B more. The floating feeling of the place where you are is more realistic. I can feel it.
Moreover, by providing the corridor-like 2nd observation part 3B, the garden 2 can be enjoyed from any position over the entire circumference, and a more varied visual effect can be enjoyed.
Furthermore, when a high tree is planted in the garden, the side of the high tree can be restrained over the entire circumference by the second observation part surrounding the garden. As a result, it is easy to prevent Takagi from falling or falling from the rooftop.
Further, the windbreak screen 7 makes it possible to reduce the wind hitting the garden 2.
Therefore, the wind damage to the plant planted in the garden 2 can be prevented, and the environment for viewing the garden 2 can be improved.

防風スクリーンを設けることによる防風効果を風洞実験によって求めた（図４（ａ）参照）。
測点は、図４（ｂ）に示す１１ポイントを設定し、それぞれにおける風荷重を求めた。
この結果から、本来であれば大きな風荷重が作用するところを、１０〜６５Ｎ／ｍ3に抑制できていることがわかる。
注１）瞬間最大風速は、風洞実験により得られた風速比の１６風向中の最大値を用い、また、瞬間最大風速と１０分間平均風速の比（ガストファクター）を２．０と仮定し算出
注２）風荷重は、次式により算出
Ｗ＝０．６Ｖ２×Ｃｆ×φ
Ｗ；風荷重（Ｎ／ｍ3）
Ｖ；瞬間最大風速（ｍ／ｓ）
Ｃｆ；風力係数（Ｃｆ＝１．２と仮定）
φ；充実率（葉の投影面積／植栽の外郭面積、φ＝０．７と仮定） The windproof effect by providing the windscreen was determined by wind tunnel experiments (see FIG. 4A).
As the measurement points, 11 points shown in FIG. 4B were set, and the wind load at each point was obtained.
From this result, it can be seen that originally a large wind load can be suppressed to 10 to 65 N / m 3 .
Note 1) The maximum instantaneous wind speed is calculated by using the maximum value in the 16 wind directions of the wind speed ratio obtained from the wind tunnel experiment, and assuming that the ratio (gust factor) between the instantaneous maximum wind speed and the average wind speed for 10 minutes is 2.0. Note 2) Wind load is calculated by the following formula. W = 0.6V2 × Cf × φ
W: Wind load (N / m 3 )
V: Maximum instantaneous wind speed (m / s)
Cf: Wind force coefficient (assuming Cf = 1.2)
φ: Filling rate (projected area of leaves / outside area of planting, assuming φ = 0.7)
