Description

【発明の属する技術分野】
本発明は、高層建築物の構造躯体の外側に設ける耐風外壁構造に関する。
【0002】
【従来の技術】
超高層の建築物は、地震や強風による風荷重を受けることにより、揺動する場合がある。この建築物に生じた揺動を低減するための制振方法は多々提案されている。
制振方法の一つとして、建築物のカーテンウォールを制振機構とする技術も提案されており、例えば特開平6−10535号公報、特開平11−293811号公報及び、特開平11−293812号公報に示される技術などが挙げられる。
これらのカーテンウォールは、一定の大きさに分割されて建築物の周囲に設置されており、この分割された個々のカーテンウォールが揺動することによって、強風や地震による建築物の揺れをパッシブ制振するようになっている。
【0003】
【発明が解決しようとする課題】
このようにカーテンウォールを用いて振動している建築物を制振させる技術は多々提案されているが、強風による風荷重を建築物の構造躯体へ伝えない技術は提案されていない。
【0004】
本発明の課題は、高層建築物の構造躯体を強風による風荷重から守る耐風外壁構造を提供することである。
【0005】
【課題を解決するための手段】
以上の課題を解決すべく本発明は、例えば図1に示すように、高層建築物(6)の構造躯体(2)の外側に設ける耐風外壁構造(1)であって、側面部(1a)及び天井部(1b)を一体的に構成し、前記構造躯体の上面(2b)から、前記構造躯体に覆い被さるように設けられ、水平方向へ可動に支持されていること、を特徴としている。
【0006】
本発明によれば、側面部及び天井部を一体的に構成した耐風外壁構造を、高層建築物の構造躯体に覆い被さるように設置し、水平方向へ可動にしたことにより、高層建築物に強い風が当たっても耐風外壁構造が水平方向に動くようになるため、構造躯体に直接風荷重が加わらなくなる。従って、強風によって高層建築物が揺動するのを抑えることができる。
【0007】
また、本発明は、上記の耐風外壁構造であって、例えば図1に示すように、前記構造躯体との間に減衰機構または緩衝部材(5)のいずれかを設けていることを特徴としている。
【0008】
ここで、減衰機構または緩衝部材は、耐風外壁構造の動きのエネルギーを吸収・放出などして、直接構造躯体に伝えないようにするためのものであり、減衰性や緩衝性を有する塑性材料を用いても良いし、機械的に減衰や緩衝を行う機構を設けても良い。
【0009】
本発明によれば、耐風外壁構造と構造躯体との間に減衰機構または緩衝部材を設けたことにより、耐風外壁構造の揺動は減衰あるいは緩衝される。従って、強風による耐風外壁構造の振動は低減され、構造躯体により伝わりにくくすることができる。
【0010】
【発明の実施の形態】
以下、図を参照して本発明の実施の形態を詳細に説明する。
【0011】
<第一の実施の形態例>
耐風外壁1は、側面部1a及び天井部1bを有し、底面部を持たない筒状であり、側面部1a及び天井部1bが、一体的になるように形成する。また、耐風外壁1の内側は、構造躯体2の外形と略同一の形状に形成され、内側に構造躯体2が完全に入る形状とする。
ここで、耐風外壁1を形成する材質は、周知のカーテンウォールと同様のもので良く、例えば金属や、ガラス、ブロック、プレキャスト等が挙げられる。
【0012】
構造躯体2は、上面部(屋上部分)2bに2次元滑り支承3を備えている。この2次元滑り支承3は、2方向ローラによって形成された支承であり、上部にて支持した物体を2次元方向に可動となるように支持することが可能となっている。
【0013】
耐風外壁1は、図1に示すように、構造躯体2の上部から覆い被さるように構造躯体2に設置され、天井部1bの下面が2次元滑り支承3に当接する。これにより、耐風外壁1の鉛直荷重の支持は2次元滑り支承3によって行われる。耐風外壁1の下端は、耐風外壁1が揺動できるよう、固定しないものとする。
【0014】
耐風外壁1の側面部1aの内側面と、構造躯体2の側面2aとの間には、一定の隙間4ができるように形成されており、この隙間4には減衰機構または緩衝部材5が設置されている。ここで減衰機構または緩衝部材5は、振動を減衰または緩衝する性質を持つ塑性材料を用いても良いし、機械的に減衰または緩衝を行う機構を用いても良い。
また、図2(a)に示すように耐風外壁1の側面1aの内側と構造躯体2の側面2aに突出部7,8を設ける。耐風外壁1側の突起部7は、構造躯体2側の突起部8より下方になるように設けておく。
【0015】
上記のように耐風外壁1を構造躯体2の外側に設置して形成した高層建築物6に強風が当たると、外側の耐風外壁1のみが風を受けて水平方向に揺れ動き、やがてこの耐風外壁1の揺動も減衰機構5によって減衰され停止する。
また、地震等により構造躯体2に破壊が生じた場合、耐風外壁1の端部が着地することにより耐風外壁1が自立し、図2(b)に示すように、内側の突出部7で構造躯体2の突出部8を支持して、構造躯体2が完全に崩壊するのを防止することも可能となる。
【0016】
このように、上記実施の形態の耐風外壁構造によれば、耐風外壁1で構造躯体2の全体を覆い、その耐風外壁1を2次元滑り支承3で支持するようにしたことにより、強風が高層建築物6に当たった場合でも、耐風外壁1のみが揺れ、内側の構造躯体2には風荷重が直接加わらなくなる。また、耐風外壁1と構造躯体2との間に減衰機構5を設けたことにより、耐風外壁1の振動が減衰あるいは緩衝されるので、構造躯体2には振動が伝わりにくくなる。
また、構造躯体2に破壊が生じてしまった場合に、耐風外壁1がサポート材の役割を果たし完全に崩壊するのを防ぐことが可能である。
【0017】
<第二の実施の形態例>
耐風外壁9は、図3に示すように、側面部9a及び天井部9bを一体的に有する上端部9cと、側面部9aのみからなる筒状の下部9dとから構成されている。耐風外壁9の上端部9cは構造躯体2の側面2a上部と、上面部2bとに覆い被せることができるよう内側を構造躯体2の上部の外形と略同一の形状に形成する。また、下部9dは、構造躯体2の側面部2aの周囲に設置できるよう、内側が構造躯体2の側面部2aの外形と略同一の形状に形成し、耐風外壁9の上端部9c及び下部9dとで、構造躯体2を完全に覆うことができる構造となっている。
耐風外壁9を形成する材質は、第一の実施の形態例と同様に、周知のカーテンウォールと同様のもので良く、例えば金属や、ガラス、ブロック、プレキャスト等が挙げられる。
【0018】
構造躯体2は、第一の実施の形態例と同様に、上面部(屋上部分)2bに2次元滑り支承3を備えている。また、一定の高さの側面部2aには梁2cが構造躯体2の外側方向へ突出するように設けられており、この梁2にも2次元滑り支承3が設けられている。
【0019】
耐風外壁9は、図2に示すように、上端部9cを構造躯体2の上部から覆い被さるように構造躯体2に設置し、天井部9bの下面が2次元滑り支承3に当接する。これにより、耐風外壁9の上端部9cの鉛直荷重の支持は2次元滑り支承3によって行われる。上端部9cの下端は固定せず、上端部9cが揺動可能になっている。
また、耐風外壁9の下部9dは、構造躯体2の側面2aを囲むように配置され、上端で構造躯体2の側面2aに設けられた梁2cの2次元滑り支承3に支持される。下部9dの下端も上端部9cの下端と同様に固定は行わない。これにより、下部9dも揺動できるようになっている。なお、設置する耐風外壁9の下部9dの数は、構造躯体2の高さ及び、下部9dの高さによって、任意に設定できるものとする。
【0020】
耐風外壁9の側面部9aの内側面と、構造躯体2の側面2aとの間には、第一の実施の形態例と同様に、一定の隙間4ができるように形成されており、この隙間4には減衰機構または緩衝部材5が設置されている。ここで減衰機構または緩衝部材5は、振動を減衰あるいは緩衝する性質を持つ塑性材料であっても、機械的に減衰あるいは緩衝を行う機構であっても良い。
【0021】
上述したように耐風外壁9を構造躯体2の外側に設置して形成した高層建築物6に強風が当たると、外側の耐風外壁9(上端部9c及び下部9d)のみが風を受けて水平方向に揺れ動き、やがて減衰機構5によって減衰され停止する。
【0022】
このように、上記実施の形態の耐風外壁構造によれば、耐風外壁9で構造躯体2の全体を覆い、その耐風外壁9を2次元滑り支承3で支持するようにしたことにより、強風が高層建築物6に当たった場合でも、耐風外壁9のみが水平方向に揺れ動き、風荷重は直接構造躯体2には加わらなくなる。また、耐風外壁9と構造躯体2との間に減衰機構5を設けたことにより、耐風外壁9の振動が減衰されるので、構造躯体2には振動が伝わりにくくなる。
【0023】
<第三の実施の形態例>
耐風外壁10は、側面部10a及び天井部10bを一体的に有し、底面部を持たない筒状になるように形成する。また、耐風外壁10の内側は構造躯体2の外形と略同一の形状に形成され、内側に構造躯体2が完全に入る形状とする。
ここで、耐風外壁10を形成する材質は、第一の実施の形態例及び第二の実施の形態例と同様に、周知のカーテンウォールと同様のもので良く、例えば金属や、ガラス、ブロック、プレキャスト等が挙げられる。
また、耐風外壁の端部には、二次元ローラ11が複数取付ける。
【0024】
耐風外壁10は、図4に示すように、構造躯体2の上部から覆い被さるように構造躯体2に設置され、耐風外壁の端部に設けた二次元ローラ11で地盤上に自立するようになっている。
【0025】
耐風外壁10の側面部10aの内側面と、構造躯体2の側面2aとの間には、一定の隙間4ができるように形成されており、この隙間4には、第一の実施の形態例と同様に、振動を減衰あるいは緩衝させる性質を持つ塑性材料あるいは機械的な減衰あるいは緩衝を行う機器からなる減衰機構または緩衝部材5が設置されている。
【0026】
上記のように耐風外壁10を構造躯体2の外側に設置して形成した高層建築物6に強風が当たると、外側の耐風外壁10のみが風を受けて二次元ローラ11により動く。この耐風外壁の動きは、減衰機構5によって減衰され停止する。
なお、本実施の形態例の耐風外壁及び構造躯体2にも第一の実施の形態例と同様に図2に示すような突出部7,8を設けることにより、構造躯体2に破壊が生じた際に耐風外壁10をサポート材とすることもできる。
【0027】
このように、上記実施の形態の耐風外壁構造によれば、耐風外壁10で構造躯体2の全体を覆い、その耐風外壁10を下端に設けた二次元ローラ11で支持するようにしたことにより、強風が高層建築物6に当たった場合でも、耐風外壁10のみが水平方向へ動き、内側の構造躯体2には風荷重が直接加わらなくなる。また、耐風外壁10と構造躯体2との間に減衰機構5を設けたことにより、耐風外壁10の動きが減衰されるので、構造躯体2には振動がより伝わりにくくすることができる。
【0028】
なお、以上の実施の形態例においては、図1及び図2中に、構造躯体の上面部に設置する2次元滑り支承を2つづつ記載してあるが、本発明はこれに限定されるものではなく、耐風外壁を確実に支持できる数であればいくつであっても良い。
また、減衰機構の数、二次元ローラの数等も任意であり、その他、具体的な細部構造等についても適宜に変更可能であることは勿論である。
【0029】
【発明の効果】
本発明によれば、耐風外壁構造を高層建築物の構造躯体に覆い被さるようにし、構造躯体の上面に設けた略水平方向への滑り支承で天井部を支持されることにより、高層建築物に強い風が当たっても耐風外壁構造のみが水平方向に揺れ動き、風荷重が直接構造躯体に加わらなくなる。また、万が一、構造躯体に破壊が生じた場合でも、耐風外壁構造がサポート材となり、崩壊を防止することができる。
【0030】
また、本発明によれば、耐風外壁構造と構造躯体との間に減衰機構または緩衝部材を設けたことにより、耐風外壁構造の揺動を減衰または緩衝する。従って、風による耐風外壁構造の振動は低減されて構造躯体に伝わりにくくすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a wind-resistant outer wall structure provided outside a structural frame of a high-rise building.
[0002]
[Prior art]
High-rise buildings may swing when subjected to wind loads caused by earthquakes or strong winds. There have been many proposals for vibration control methods to reduce the fluctuations generated in the building.
As one of the vibration damping methods, a technique using a curtain wall of a building as a vibration damping mechanism has been proposed. For example, Japanese Patent Laid-Open Nos. 6-10535, 11-293811, and 11-293812. The technique etc. which are shown by the gazette are mentioned.
These curtain walls are divided into a certain size and installed around the building, and the individual divided curtain walls swing to passively control the shaking of the building due to strong winds and earthquakes. Shake.
[0003]
[Problems to be solved by the invention]
As described above, many techniques for damping a building that vibrates using a curtain wall have been proposed. However, no technique has been proposed for not transmitting a wind load caused by a strong wind to a structural frame of a building.
[0004]
The subject of this invention is providing the wind-resistant outer wall structure which protects the structural frame of a high-rise building from the wind load by a strong wind.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is a wind resistant outer wall structure (1) provided on the outside of a structural frame (2) of a high-rise building (6) as shown in FIG. And the ceiling portion (1b) are integrally formed, and are provided so as to cover the structure housing from the upper surface (2b) of the structure housing, and are supported movably in the horizontal direction.
[0006]
According to the present invention , the wind-resistant outer wall structure in which the side surface portion and the ceiling portion are integrally formed is installed so as to cover the structural frame of the high-rise building and is movable in the horizontal direction, thereby being strong against the high-rise building. Since the wind-resistant outer wall structure moves in the horizontal direction even when it is hit by wind, the wind load is not directly applied to the structural frame. Therefore, the high-rise building can be prevented from swinging due to the strong wind.
[0007]
Further, the present invention is the wind resistant outer wall structure described above, and is characterized in that either a damping mechanism or a buffer member (5) is provided between the structure housing as shown in FIG. .
[0008]
Here, the damping mechanism or the buffer member is for absorbing and releasing the energy of the movement of the wind-resistant outer wall structure so as not to transmit it directly to the structural housing. A damping material or a buffering plastic material is used. It may be used, or a mechanism for mechanically damping and buffering may be provided.
[0009]
According to the present invention , the damping mechanism or the buffer member is provided between the wind resistant outer wall structure and the structural housing, so that the swinging of the wind resistant outer wall structure is attenuated or buffered. Therefore, the vibration of the wind resistant outer wall structure due to strong winds is reduced and can be made difficult to be transmitted by the structural frame.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0011]
<First embodiment>
The wind-resistant outer wall 1 has a side surface portion 1a and a ceiling portion 1b, has a cylindrical shape without a bottom surface portion, and is formed so that the side surface portion 1a and the ceiling portion 1b are integrated. Further, the inside of the wind-resistant outer wall 1 is formed in a shape that is substantially the same as the outer shape of the structural housing 2, and the structural housing 2 completely enters the inside.
Here, the material forming the wind-resistant outer wall 1 may be the same as that of a well-known curtain wall, and examples thereof include metal, glass, block, and precast.
[0012]
The structural housing 2 includes a two-dimensional sliding bearing 3 on an upper surface portion (a rooftop portion) 2b. The two-dimensional sliding bearing 3 is a bearing formed by a two-way roller, and can support an object supported on the upper part so as to be movable in a two-dimensional direction.
[0013]
As shown in FIG. 1, the wind resistant outer wall 1 is installed on the structural housing 2 so as to cover the upper portion of the structural housing 2, and the lower surface of the ceiling portion 1 b abuts against the two-dimensional sliding bearing 3. Thereby, the vertical load of the wind resistant outer wall 1 is supported by the two-dimensional sliding bearing 3. The lower end of the wind resistant outer wall 1 is not fixed so that the wind resistant outer wall 1 can swing.
[0014]
A constant gap 4 is formed between the inner side surface of the side surface portion 1 a of the wind-resistant outer wall 1 and the side surface 2 a of the structural housing 2, and a damping mechanism or a buffer member 5 is installed in the gap 4. Has been. Here, the damping mechanism or the buffer member 5 may be a plastic material having a property of damping or buffering vibrations, or may be a mechanism for mechanically damping or buffering.
Further, as shown in FIG. 2A, projecting portions 7 and 8 are provided on the inner side of the side surface 1 a of the wind-resistant outer wall 1 and the side surface 2 a of the structural housing 2. The protrusion 7 on the wind-resistant outer wall 1 side is provided below the protrusion 8 on the structure housing 2 side.
[0015]
When strong wind hits the high-rise building 6 formed by installing the wind-resistant outer wall 1 on the outside of the structural frame 2 as described above, only the outer wind-resistant outer wall 1 receives the wind and swings in the horizontal direction, and eventually the wind-resistant outer wall 1 Is also attenuated by the damping mechanism 5 and stopped.
In addition, when the structural housing 2 is broken due to an earthquake or the like, the wind-resistant outer wall 1 is self-supported by the end of the wind-resistant outer wall 1 landing, and as shown in FIG. It is also possible to support the protrusion 8 of the housing 2 and prevent the structural housing 2 from being completely collapsed.
[0016]
Thus, according to the wind-resistant outer wall structure of the above embodiment, the wind-resistant outer wall 1 covers the entire structure housing 2 and the wind-resistant outer wall 1 is supported by the two-dimensional sliding bearing 3, so that strong winds are high-rise. Even when it hits the building 6, only the wind-resistant outer wall 1 is shaken, and the wind load is not directly applied to the inner structural frame 2. Further, since the damping mechanism 5 is provided between the wind-resistant outer wall 1 and the structural housing 2, the vibration of the wind-resistant outer wall 1 is attenuated or buffered, so that the vibration is hardly transmitted to the structural housing 2.
In addition, when the structural housing 2 is broken, it is possible to prevent the wind-resistant outer wall 1 from acting as a support material and being completely collapsed.
[0017]
<Second Embodiment>
As shown in FIG. 3, the wind-resistant outer wall 9 includes an upper end portion 9c integrally including a side surface portion 9a and a ceiling portion 9b, and a cylindrical lower portion 9d composed of only the side surface portion 9a.

Further, the lower portion 9d is formed so that the inside thereof is substantially the same as the outer shape of the side surface portion 2a of the structural housing 2 so that the lower portion 9d can be installed around the side surface portion 2a of the structural housing 2. Thus, the structure housing 2 can be completely covered.
The material forming the wind-resistant outer wall 9 may be the same as that of a known curtain wall as in the first embodiment, and examples thereof include metals, glass, blocks, and precasts.
[0018]
Similar to the first embodiment, the structural housing 2 includes a two-dimensional sliding bearing 3 on the upper surface portion (rooftop portion) 2b. Further, a beam 2c is provided on the side surface portion 2a having a constant height so as to protrude outward from the structural housing 2, and a two-dimensional sliding bearing 3 is provided on the beam 2 as well.

As shown in FIG. 2, the wind-resistant outer wall 9 is installed on the structural housing 2 so that the upper end portion 9 c covers the upper portion of the structural housing 2, and the lower surface of the ceiling portion 9 b abuts on the two-dimensional sliding bearing 3. Thereby, the vertical load of the upper end portion 9 c of the wind resistant outer wall 9 is supported by the two-dimensional sliding bearing 3. The lower end of the upper end portion 9c is not fixed, and the upper end portion 9c can swing.
The lower part 9d of the wind-resistant outer wall 9 is disposed so as to surround the side surface 2a of the structural housing 2, and is supported at the upper end by the two-dimensional sliding bearing 3 of the beam 2c provided on the side surface 2a of the structural housing 2. The lower end of the lower portion 9d is not fixed similarly to the lower end of the upper end portion 9c. Thereby, the lower part 9d can also rock | fluctuate. In addition, the number of the lower parts 9d of the wind-resistant outer wall 9 to be installed can be arbitrarily set according to the height of the structural housing 2 and the height of the lower part 9d.

Thus, according to the wind-resistant outer wall structure of the above embodiment, the wind-resistant outer wall 9 covers the entire structure housing 2 and the wind-resistant outer wall 9 is supported by the two-dimensional sliding bearing 3, so that strong winds are high-rise. Even when it hits the building 6, only the wind-resistant outer wall 9 swings in the horizontal direction, and the wind load is not directly applied to the structural frame 2. Further, by providing the damping mechanism 5 between the wind-resistant outer wall 9 and the structural housing 2, the vibration of the wind-resistant outer wall 9 is attenuated, so that the vibration is hardly transmitted to the structural housing 2.
[0023]
<Third embodiment>
The wind-resistant outer wall 10 is integrally formed with a side surface portion 10a and a ceiling portion 10b, and is formed in a cylindrical shape without a bottom surface portion. In addition, the inside of the wind-resistant outer wall 10 is formed in a shape substantially the same as the outer shape of the structural housing 2, and the structural housing 2 is completely inside.
Here, the material forming the wind-resistant outer wall 10 may be the same as a well-known curtain wall, like the first embodiment and the second embodiment, for example, metal, glass, block, Examples include precast.
A plurality of two-dimensional rollers 11 are attached to the end of the wind resistant outer wall.
[0024]
As shown in FIG. 4, the wind resistant outer wall 10 is installed on the structural casing 2 so as to cover the top of the structural casing 2, and becomes independent on the ground by a two-dimensional roller 11 provided at the end of the wind resistant outer wall. ing.
[0025]
A constant gap 4 is formed between the inner side surface of the side surface portion 10a of the wind-resistant outer wall 10 and the side surface 2a of the structural housing 2, and this gap 4 has a first embodiment. In the same manner as described above, a damping mechanism or a buffering member 5 made of a plastic material having a property of damping or buffering vibrations or a mechanical damping or buffering device is installed.
[0026]
When strong wind strikes the high-rise building 6 formed by installing the wind-resistant outer wall 10 outside the structural housing 2 as described above, only the outer wind-resistant outer wall 10 receives the wind and moves by the two-dimensional roller 11. The movement of the wind resistant outer wall is attenuated by the damping mechanism 5 and stopped.
In addition, the wind-resistant outer wall and the structural housing 2 of the present embodiment are also provided with the protrusions 7 and 8 as shown in FIG. 2 as in the first embodiment, so that the structural housing 2 is broken. In this case, the wind-resistant outer wall 10 can be used as a support material.
[0027]
Thus, according to the wind-resistant outer wall structure of the above embodiment, the entire structure housing 2 is covered with the wind-resistant outer wall 10, and the wind-resistant outer wall 10 is supported by the two-dimensional roller 11 provided at the lower end. Even when a strong wind hits the high-rise building 6, only the wind-resistant outer wall 10 moves in the horizontal direction, and the wind load is not directly applied to the inner structural frame 2. In addition, since the movement of the wind resistant outer wall 10 is attenuated by providing the damping mechanism 5 between the wind resistant outer wall 10 and the structural housing 2, it is possible to make it difficult for vibration to be transmitted to the structural housing 2.
[0028]
In the above embodiment, two two-dimensional sliding bearings installed on the upper surface of the structural housing are described in FIGS. 1 and 2, but the present invention is not limited to this. Instead, any number is acceptable as long as the windproof outer wall can be reliably supported.
In addition, the number of damping mechanisms, the number of two-dimensional rollers, and the like are arbitrary, and it is needless to say that specific detailed structures and the like can be appropriately changed.

【The invention's effect】
According to the present invention , the wind-resistant outer wall structure is covered with the structural frame of the high-rise building, and the ceiling is supported by the substantially horizontal sliding support provided on the upper surface of the structural frame. Even if a strong wind strikes, only the wind-resistant outer wall structure swings in the horizontal direction, and the wind load is not directly applied to the structural frame. In the unlikely event that the structural housing breaks down, the wind-resistant outer wall structure serves as a support material and can be prevented from collapsing.
[0030]
In addition, according to the present invention , the damping mechanism or the buffer member is provided between the wind-resistant outer wall structure and the structural housing, so that the swinging of the wind-resistant outer wall structure is attenuated or buffered. Therefore, the vibration of the wind-resistant outer wall structure due to the wind can be reduced and can hardly be transmitted to the structural frame.
