Description

本発明は、建物の外壁部を構成するダブルスキン構造に関する。   The present invention relates to a double skin structure constituting an outer wall portion of a building.

従来より、建物の外壁に面状の部材を二重に配置して、これら部材同士の隙間を中空層としたダブルスキンと呼ばれる構造がある(特許文献1参照)。
このダブルスキン構造では、冬季には、中空層に空気を密封して空気層とすることにより、この外壁の断熱性能を向上させる(例えば、特許文献1、2参照)。
2. Description of the Related Art Conventionally, there is a structure called a double skin in which planar members are doubled on the outer wall of a building and a gap between these members is a hollow layer (see Patent Document 1).
In the double skin structure, in the winter season, the heat insulation performance of the outer wall is improved by sealing the air in the hollow layer to form an air layer (see, for example, Patent Documents 1 and 2).

特開2013−177756号公報JP 2013-177756 A 特開2013−181333号公報JP 2013-181333 A

しかしながら、中空層に空気を密封しても、空気の主要成分である酸素や窒素のような等核二原子分子は、振動はしても双極子モーメントは全く変化しない。したがって、実際には、断熱性能をそれほど期待できず、屋内から屋外に熱が逃げるのを抑制できない、という課題があった。   However, even if air is sealed in the hollow layer, the dipole moment of isonuclear diatomic molecules such as oxygen and nitrogen, which are the main components of air, does not change at all even if they vibrate. Therefore, in practice, there is a problem that heat insulation performance cannot be expected so much and heat cannot be prevented from escaping from indoors to outdoors.

さらに、従来のダブルスキンの厚さは60cm程度であったが、近年では、建物有効面積の確保から20cm程度まで薄型化しており、これに伴いダブルスキン構造の中空層の体積が縮減されるため、冬季の断熱性能がさらに低下するといった課題があった。   Furthermore, the thickness of the conventional double skin was about 60 cm. However, in recent years, since the effective area of the building has been reduced to about 20 cm, the volume of the hollow layer of the double skin structure is reduced accordingly. There was a problem that the thermal insulation performance in winter was further deteriorated.

本発明は、屋内から屋外に熱が逃げるのを確実に抑制できるダブルスキン構造を提供することを目的とする。   An object of this invention is to provide the double skin structure which can suppress reliably that a heat | fever escapes from indoors to the outdoors.

請求項1に記載のダブルスキン構造(例えば、後述のダブルスキン構造1)は、建物(例えば、後述の建物2)の外壁部を構成するダブルスキン構造であって、外側面材(例えば、後述の外側面材10)と、当該外側面材の屋内側に所定間隔離れて設けられた内側面材(例えば、後述の内側面材20)と、を備え、前記外側面材および前記内側面材の少なくとも一部は、ガラス材により形成され、前記外側面材と前記内側面材との間には、上下方向に連通する中空層(例えば、後述の中空層30)が設けられ、当該中空層には、赤外線を吸収する気体が充填されることを特徴とする。   The double skin structure (for example, double skin structure 1 described later) according to claim 1 is a double skin structure that constitutes an outer wall portion of a building (for example, building 2 described later), and is an outer surface material (for example, described later). And an inner surface material (for example, an inner surface material 20 described later) provided on the indoor side of the outer surface material at a predetermined interval, the outer surface material and the inner surface material. Is formed of a glass material, and a hollow layer (for example, a hollow layer 30 described later) is provided between the outer side surface material and the inner side surface material in the vertical direction. Is filled with a gas that absorbs infrared rays.

請求項3に記載のダブルスキン構造は、前記赤外線を吸収する気体は、二酸化炭素であることを特徴とする。   The double skin structure according to claim 3 is characterized in that the gas that absorbs infrared rays is carbon dioxide.

ここで、赤外線を吸収する気体とは、極性の共有結合を持つ分子であり、自然光に含まれる赤外線を吸収するものであって、O−H−O、(CH2)2−、−CH3、C−H、=CH−H、>C=C<H、≡CH、C≡C、C=C=C、=C−H、C=C、−C−H、O−H、C=O、C−H、C−O−C、N−H、C−Nのいずれかの結合を有するものである。   Here, the gas that absorbs infrared rays is a molecule having a polar covalent bond, and absorbs infrared rays contained in natural light, and includes O—H—O, (CH 2) 2 —, —CH 3, C -H, = CH-H,> C = C <H, ≡CH, C≡C, C = C = C, = C-H, C = C, -C-H, OH, C = O, It has a bond of any one of C—H, C—O—C, N—H, and C—N.

この発明によれば、ダブルスキン構造の中空層に、赤外線を吸収する気体を充填した。この充填した気体が赤外線を吸収することにより、断熱性能を発揮して温室効果が生じるので、屋内から屋外に熱が逃げるのを確実に抑制できる。   According to this invention, the double-skin structure hollow layer is filled with the gas that absorbs infrared rays. The filled gas absorbs infrared rays, thereby exhibiting heat insulation performance and a greenhouse effect. Therefore, it is possible to reliably suppress the escape of heat from indoors to the outdoors.

赤外線を吸収する気体としては、可燃性が低くて取り扱いが容易なものが好ましく、代表例として二酸化炭素が挙げられる。この二酸化炭素は、15μmあるいは4.3μm付近の波長の赤外線を吸収する。   As the gas that absorbs infrared rays, a gas that has low flammability and is easy to handle is preferable, and a representative example is carbon dioxide. This carbon dioxide absorbs infrared rays having a wavelength in the vicinity of 15 μm or 4.3 μm.

現在、二酸化炭素は地球温暖化の主要因であると考えられているが、この二酸化炭素による温室効果について、以下のような研究がなされている(「地球温暖化装置を用いた理科学習の実践」、中山慎也、村上隆正、重松宏武、島根大学教育学部紀要(教育科学)第42巻、p7〜11、平成20年12月)。   Currently, carbon dioxide is considered to be the main cause of global warming, but the following research has been conducted on the greenhouse effect of carbon dioxide (“Practice of science learning using global warming devices” "Shinya Nakayama, Takamasa Murakami, Hirotake Shigematsu, Bulletin of Faculty of Education, Shimane University (Educational Sciences), Vol. 42, p7-11, December 2008).

まず、地球の大気層を模擬して、2つのアクリル製の透明球体(直径40cm)を製作する。次に、一方の球体内には、地球温暖化が発生していない大気を模して、99.99%の窒素ガスを充填し、他方の球体内には、地球温暖化が発生した大気を模して、99.5%の二酸化炭素を充填する。次に、昼間を模擬して外部から15分間赤外線を照射し、その後、赤外線の照射を中止して、球体内部の温度変化をモニタリングする。   First, two acrylic transparent spheres (diameter 40 cm) are manufactured by simulating the atmosphere layer of the earth. Next, one sphere is filled with 99.99% nitrogen gas, imitating the atmosphere in which global warming has not occurred, and the other sphere is filled with the atmosphere in which global warming has occurred. Simulate and fill with 99.5% carbon dioxide. Next, in the daytime, infrared irradiation is performed for 15 minutes from the outside, and then the infrared irradiation is stopped and the temperature change inside the sphere is monitored.

その結果、赤外線を照射した期間では、窒素ガス系の球体および二酸化炭素系の球体の温度は、ほぼ同様に上昇した。しかし、赤外線の照射を中止したところ、二酸化炭素系の球体の温度は、窒素ガス系の球体の温度と比較して、最大で1.3度高くなった。したがって、二酸化炭素により温室効果が生じることが判る。   As a result, the temperature of the nitrogen gas sphere and the carbon dioxide sphere rose in substantially the same manner during the period of irradiation with infrared rays. However, when the irradiation with infrared rays was stopped, the temperature of the carbon dioxide-based sphere became 1.3 degrees higher than the temperature of the nitrogen gas-based sphere. Therefore, it can be seen that carbon dioxide produces a greenhouse effect.

請求項2に記載のダブルスキン構造は、前記外側面材には、普通ガラス(例えば、後述の普通ガラス12)が用いられ、前記内側面材には、低反射ガラス(例えば、後述の低反射ガラス22)が用いられ、当該低反射ガラスの前記中空層側には、金属膜が形成されることを特徴とする。   In the double skin structure according to claim 2, ordinary glass (for example, later-described ordinary glass 12) is used for the outer surface material, and low-reflection glass (for example, later-described low-reflection material) is used for the inner surface material. Glass 22) is used, and a metal film is formed on the hollow layer side of the low reflection glass.

この発明によれば、内側面材に低反射ガラスを用いたので、屋内から中空層に向かう熱線(赤外線)がこの低反射ガラスに反射されるから、屋内から中空層に伝わる放射熱を抑制できる。   According to this invention, since the low reflection glass is used for the inner side surface material, the heat rays (infrared rays) from the indoor toward the hollow layer are reflected by the low reflection glass, so that the radiant heat transmitted from the indoor to the hollow layer can be suppressed. .

本発明によれば、ダブルスキン構造の中空層に、赤外線を吸収する気体を充填した。この充填した気体が赤外線を吸収することにより、断熱性能を発揮して温室効果が生じるので、屋内から屋外に熱が逃げるのを確実に抑制できる。   According to the present invention, a double-skin structure hollow layer is filled with a gas that absorbs infrared rays. The filled gas absorbs infrared rays, thereby exhibiting heat insulation performance and a greenhouse effect. Therefore, it is possible to reliably suppress the escape of heat from indoors to the outdoors.

以下、本発明の一実施形態について、図面を参照しながら説明する。
図1は、本発明の一実施形態に係るダブルスキン構造1の断面図である。
ダブルスキン構造1は、建物2の外壁部を構成するものである。図1では、建物2のn階から(n+3)階までを示している。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a double skin structure 1 according to an embodiment of the present invention.
The double skin structure 1 constitutes an outer wall portion of the building 2. FIG. 1 shows the building 2 from the nth floor to the (n + 3) floor.

このダブルスキン構造1は、外壁面を構成する面状の外側面材10と、この外側面材10の屋内側に所定間隔離れて設けられた面状の内側面材20と、を備える。
外側面材10は、格子状に設けられた枠部材11と、この枠部材11に嵌め込まれた普通ガラス12と、を備える。
内側面材20は、格子状に設けられた枠部材21と、この枠部材21に嵌め込まれた低反射(Low−e)ガラス22と、を備える。この低反射ガラス22は、外側(つまり後述の中空層30側)の表面に金属膜が形成されたガラスである。
The double skin structure 1 includes a planar outer surface material 10 constituting an outer wall surface, and a planar inner surface material 20 provided at a predetermined interval on the indoor side of the outer surface material 10.
The outer surface material 10 includes a frame member 11 provided in a lattice shape, and a normal glass 12 fitted into the frame member 11.
The inner surface material 20 includes a frame member 21 provided in a lattice shape, and a low reflection (Low-e) glass 22 fitted in the frame member 21. The low reflection glass 22 is a glass in which a metal film is formed on the outer surface (that is, the hollow layer 30 side described later).

外側面材10と内側面材20との間には、上下方向に連通する中空層30が設けられる。この中空層30は、ここでは2フロア毎に、仕切部材31で仕切られている。
外側面材10のうち仕切られた中空層30の下部には、屋外と中空層30とを連通しかつ開閉可能な下部換気口32が設けられ、中空層30の上部には、屋外と中空層30とを連通しかつ開閉可能な上部換気口33が設けられる。
A hollow layer 30 communicating in the vertical direction is provided between the outer side surface material 10 and the inner side surface material 20. Here, the hollow layer 30 is partitioned by a partition member 31 every two floors.
A lower ventilation port 32 that allows the outdoor and the hollow layer 30 to communicate with each other and that can be opened and closed is provided at the lower part of the partitioned hollow layer 30 of the outer side surface material 10, and the outdoor and the hollow layer are provided above the hollow layer 30. 30 is provided with an upper ventilation port 33 that communicates with 30 and can be opened and closed.

以上のダブルスキン構造1の運転方法は、例えば以下のようになる。
夏季は、屋外の気温が屋内の気温よりも高くなるため、下部換気口32および上部換気口33を開放しておく。これにより、図2(a)中の矢印で示すように、冷たい空気が下部換気口32を通って中空層30に流入し、中空層30内で暖められて上昇し、上部換気口33を通って屋外に排出されて、自然換気される。
The operation method of the above double skin structure 1 is as follows, for example.
In summer, the outdoor air temperature is higher than the indoor air temperature, so the lower ventilation port 32 and the upper ventilation port 33 are kept open. As a result, as indicated by the arrows in FIG. 2A, cold air flows into the hollow layer 30 through the lower ventilation port 32, is warmed and rises in the hollow layer 30, and passes through the upper ventilation port 33. Are discharged outdoors and are naturally ventilated.

一方、冬季は、屋外の気温が屋内の気温よりも低くなるため、図2(b)に示すように、中空層30内の空気を二酸化炭素に置き換えることで、中空層30に二酸化炭素を充填して、下部換気口32および上部換気口33を完全に密閉する。これにより、昼間は、二酸化炭素が太陽光の赤外線を吸収して温度が上昇するが、夜間になっても、温度がそれほど低下せず、温室効果により屋内の熱が屋外に逃げるのを防止する。   On the other hand, since the outdoor temperature is lower than the indoor temperature in winter, the hollow layer 30 is filled with carbon dioxide by replacing the air in the hollow layer 30 with carbon dioxide as shown in FIG. Thus, the lower ventilation port 32 and the upper ventilation port 33 are completely sealed. As a result, carbon dioxide absorbs the infrared rays of sunlight and the temperature rises during the daytime, but the temperature does not drop much even at night, preventing the indoor heat from escaping outdoors due to the greenhouse effect. .

本実施形態によれば、以下のような効果がある。
(1)ダブルスキン構造1の中空層30に赤外線を吸収する気体として二酸化炭素を充填した。この充填した二酸化炭素が赤外線を吸収することにより、断熱性能を発揮して温室効果が生じるので、屋内から屋外に熱が逃げるのを確実に抑制できる。
(2)内側面材20に低反射(Low−e)ガラス22を用いたので、屋内から中空層30に向かう熱線(赤外線)がこの低反射ガラス22に反射されるから、屋内から中空層30に伝わる放射熱を抑制できる。
According to this embodiment, there are the following effects.
(1) The hollow layer 30 of the double skin structure 1 was filled with carbon dioxide as a gas that absorbs infrared rays. The filled carbon dioxide absorbs infrared rays, thereby exhibiting heat insulation performance and producing a greenhouse effect. Therefore, it is possible to reliably suppress the escape of heat from indoors to the outdoors.
(2) Since the low reflection (Low-e) glass 22 is used for the inner side surface material 20, the heat rays (infrared rays) from the indoor toward the hollow layer 30 are reflected by the low reflection glass 22. The radiant heat transmitted to can be suppressed.

なお、本発明は前記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。   It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
