Description

本発明は、建物の外壁を構成するカーテンウォールに関する。   The present invention relates to a curtain wall constituting an outer wall of a building.

従来、建物の外壁を構成するカーテンウォールとしては、特許文献１に開示したように、インナースキンと呼ばれる室内側窓とアウタースキンと呼ばれる室外側窓とを備え、その室内側窓と室外側窓との間に中間空気層を形成し、この中間空気層を吸気口と排気口で室外に連通したダブルスキン構造のカーテンウォールが知られている。
このカーテンウォールであれば、中間空気層が断熱の役目を果たすと共に、その中間空気層に外気が流通するので、断熱性能が良い。
また、ブラインドを設けることで、そのブラインドで日射を遮り、外気を流通させることで日射熱取得を軽減できる。
特開２００１−２５３７３４号公報 Conventionally, as a curtain wall constituting the outer wall of a building, as disclosed in Patent Document 1, an indoor side window called an inner skin and an outdoor side window called an outer skin are provided. There is known a curtain wall having a double skin structure in which an intermediate air layer is formed between the two and the intermediate air layer communicates with the outside through an intake port and an exhaust port.
With this curtain wall, the intermediate air layer plays the role of heat insulation, and the outside air circulates through the intermediate air layer, so that the heat insulation performance is good.
Further, by providing a blind, it is possible to reduce solar heat acquisition by blocking solar radiation with the blind and circulating outside air.
JP 2001-253734 A

建物の外壁は、一般的に、床と天井との間の居住空間と対向したビジョン部（窓部）と、下の階の天井と上の階の床との間の上下階の境界部と対向したスパンドレル部（腰部）を備え、そのビジョン部とスパンドレル部が上下方向に交互に連続している。
前述した従来のダブルスキン構造のカーテンウォールは、前記ビジョン部と前記スパンドレル部とに亘って前記中間空気層が連続して形成され、ビジョン部の下部に吸気口を形成すると共に、スパンドレル部の上部に排気口が形成され、ビジョン部とスパンドレル部とに亘って外気が流通するので、外気が流通する中間空気層の容積が大きく、その吸気口、排気口を大きくして多量の外気が中間空気層に流入、流出するようにしている。
このために、室外からカーテンウォールを見たときに、前記吸気口、排気口が目立つので、外観の見栄えが悪いカーテンウォールとなる。
また、スパンドレル部に外気が流通するから、断熱性能が低下する。 The outer wall of a building generally has a vision part (window part) facing the living space between the floor and the ceiling, and a boundary part between the upper and lower floors between the ceiling of the lower floor and the floor of the upper floor. Opposing spandrel parts (waist parts) are provided, and the vision parts and spandrel parts are alternately continued in the vertical direction.
In the conventional double skin structure curtain wall described above, the intermediate air layer is continuously formed across the vision part and the spandrel part, and an air inlet is formed in the lower part of the vision part. Since the outside air is circulated between the vision part and the spandrel part, the volume of the intermediate air layer through which the outside air circulates is large. It flows in and out of the bed.
For this reason, when the curtain wall is viewed from the outside, the air inlet and the air outlet are conspicuous, so that the appearance of the curtain wall is poor.
Moreover, since outside air distribute | circulates to a spandrel part, heat insulation performance falls.

また、カーテンウォールの横材に吸気口、排気口を形成するのが一般的であるが、前述のように、吸気口、排気口が大きいので、大きな形状の横材を用いることになり、コストアップの要因になっていた。   In addition, it is common to form air inlets and exhausts in the curtain wall cross member. However, as mentioned above, since the air intake port and exhaust port are large, a large cross member is used. It was a factor of up.

本発明の目的は、室内側窓と室外側窓との間における外気が流通する中間空気層の容積を小さくすることで、吸気口、排気口を小さくし、部材や部品を低減させるだけでなく、熱性能の向上も図ることの横材を小さくすることができ、しかも断熱性能を向上できるカーテンウォールを提供することである。   The object of the present invention is not only to reduce the volume of the intermediate air layer through which the outside air flows between the indoor side window and the outdoor side window, thereby reducing the size of the intake and exhaust ports and reducing the number of members and parts. Further, the present invention is to provide a curtain wall capable of reducing the cross member for improving the thermal performance and also improving the heat insulation performance.

前記中間横材は、本体横材と、この本体横材よりも見込み寸法が小さい補助横材を備え、
前記本体横材は、室内側部と、この室内側部から室外側に向けてほぼ斜め下方向に湾曲した中間部と、この中間部の室外側端に設けた室外側部を有し、
前記補助横材の上面は、室外側から室内側に向けてほぼ斜め上向きに湾曲した空気ガイド部を有し、
前記本体横材を縦材に連結すると共に、前記補助横材を前記縦材の室外側寄りに、前記本体横材の室外側部よりも下方に位置し、かつその補助横材の上面と本体横材の中間部、室外側部の下面との間に隙間を形成して連結し、
前記本体横材の室内側部の下方に室内側窓を装着すると共に、前記補助横材に室外側窓を装着して中間空気層を形成し、
この中間空気層の上部を前記隙間に連通し、その隙間を中間空気層を室外に連通する排気口とし、
前記補助横材の空気ガイド部は、前記本体横材の室外側部よりも上方に突出して中間部と対向し、前記排気口は、その中間空気層に連通した流入口が室外に連通した流出口よりも上方に位置したほぼＬ字形状であることを特徴とするカーテンウォールである。 The present invention comprises a vision part facing the living space of the building, and a spandrel part facing the boundary part of the upper and lower floors of the building,
The vision unit has an intermediate air layer between the indoor side window and the outdoor side window, and the lower part of the intermediate air layer communicates with the outside through the intake port, and the upper part communicates with the outside through the exhaust port. A curtain wall in which outside air circulates only to the intermediate air layer of the section ,
A frame body having an upper frame portion and a lower frame portion with left and right vertical members, upper cross members, intermediate cross members and lower cross members,
The upper frame part is equipped with an indoor panel having fire resistance performance to form a spandrel part, and the lower frame part is equipped with an indoor side window and an outdoor side window to form a vision part having an intermediate air layer,
Forming an inlet in the lower cross member, and forming an exhaust port in the intermediate cross member so that outside air flows through the intermediate air layer;
The intermediate cross member includes a main body cross member and an auxiliary cross member having a smaller expected dimension than the main body cross member,
The main body cross member has an indoor side part, an intermediate part curved substantially obliquely downward from the indoor side part toward the outdoor side, and an outdoor side part provided at an outdoor end of the intermediate part,
The upper surface of the auxiliary cross member has an air guide portion that is curved substantially obliquely upward from the outdoor side toward the indoor side,
The main body cross member is connected to the vertical member, and the auxiliary cross member is positioned closer to the outdoor side of the vertical member and below the outdoor side portion of the main body cross member, and the upper surface of the auxiliary cross member and the main body Form a gap between the intermediate part of the cross member and the lower surface of the outdoor part,
Attaching an indoor side window below the indoor side part of the main body cross member, and attaching an outdoor side window to the auxiliary cross member to form an intermediate air layer,
The upper part of the intermediate air layer communicates with the gap, and the gap serves as an exhaust port that communicates the intermediate air layer with the outside.
The air guide part of the auxiliary cross member protrudes upward from the outdoor side part of the main body cross member and faces the intermediate part, and the exhaust port is a flow in which an inlet communicating with the intermediate air layer communicates with the outside. The curtain wall is substantially L-shaped and positioned above the outlet.

本発明においては、枠体の上枠部に、室内側パネルと室外側パネルを装着して中間空気層を有するスパンドレル部とし、
この室外側パネルとビジョン部の室外側窓を面外方向にほぼ同一位置とし、
前記スパンドレル部の中間空気層には外気が流通しないようにできる。
このようにすれば、スパンドレル部の室外側面とビジョン部の室外側面がほぼ同一に連続するから、外観の見栄えが良い。また、スパンドレル部の中間空気層には外気が流通しないので、断熱性能を向上できる。 In the present invention, on the upper frame portion of the frame body, the indoor side panel and the outdoor side panel are attached to form a spandrel portion having an intermediate air layer,
The outdoor panel and the outdoor window of the vision unit are positioned almost in the same direction in the out-of-plane direction.
Outside air can be prevented from flowing through the intermediate air layer of the spandrel portion.
In this way, the outdoor side surface of the spandrel portion and the outdoor side surface of the vision portion are substantially the same, so the appearance is good. Moreover, since outside air does not circulate through the intermediate air layer of the spandrel part, the heat insulation performance can be improved.

本発明によれば、ビジョン部の中間空気層にのみ外気が流通するので、その外気が流通する中間空気層の容積が小さく、吸気口、排気口を小さくできる。
したがって、室外からカーテンウォールを見たときに、前記吸気口、排気口が目立つことがなく、吸気口、排気口を外観上シンプルにすっきりさせることができ、外観の見栄えが良い。
また、吸気口、排気口を形成した下横材、中間横材を小さくできるので、コスト安にできる。
また、スパンドレル部には外気が流通する中間空気層がないから、断熱性能の向上がはかれる。
また、吸気口が小さいことによって、その吸気口を形成した下横材を小さくできるので、通常のカーテンウォールの下横材と同程度の大きさの下横材とすることができる。
また、本体横材と補助横材を縦材に連結することで排気口を形成できる。
また、排気口は、その流入口が流出口よりも上方に位置したほぼＬ字形状であるから、排気口から雨水等が中間空気層に浸入し難い。 According to the present invention, since the outside air flows only through the intermediate air layer of the vision unit, the volume of the intermediate air layer through which the outside air flows is small, and the intake port and the exhaust port can be reduced.
Therefore, when the curtain wall is viewed from the outside, the intake and exhaust ports are not conspicuous, and the intake and exhaust ports can be made simple and clean, and the appearance is good.
In addition, since the lower cross member and the intermediate cross member formed with the intake port and the exhaust port can be made small, the cost can be reduced.
In addition, since there is no intermediate air layer through which the outside air flows in the spandrel part, the heat insulation performance can be improved.
Further, since the lower cross member forming the intake port can be made smaller by making the intake port small, the lower cross member having the same size as the lower cross member of a normal curtain wall can be obtained.
Moreover, an exhaust port can be formed by connecting the main body cross member and the auxiliary cross member to the vertical member.
Moreover, since the inflow port has a substantially L shape with the inflow port positioned above the outflow port, rainwater or the like hardly enters the intermediate air layer from the exhaust port.

図１と図２に示すように、建物１の外壁１ａを構成するカーテンウォール１０は、ビジョン部（窓部）１０ａとスパンドレル部１０ｂを、上下方向に交互に有している。
前記建物１は、建物躯体２に床スラブ３を介して床板４を取付けた床５と、前記床スラブ３に天井板６を取付けた天井７を有し、その床５と天井７との間が建物１の居住空間（室内）８で、下の階の天井７と上の階の床５との間が建物１の上下階の境界部分９である。
前記カーテンウォール１０のビジョン部１０ａが前記居住空間８と対向し、スパンドレル部９が前記境界部分９と対向している。
この実施の形態では、ぺリカウンター４ａと天井７との間にビジョン部１０ａが対向し、その天井７と上の階のぺリカウンター４ａとの間にスパンドレル部１０ｂが対向している。
前記ビジョン部１０ａは、インナースキンと呼ばれる室内側窓１１とアウタースキンと呼ばれる室外側窓１２を備え、その室内側窓１１と室外側窓１２との間に中間空気層１３を形成している。
この中間空気層１３は、その下部に形成した吸気口１４と上部に形成した排気口１５で室外にそれぞれ連通し、前記中間空気層１３には外気が流通するようにしてビジョン部１０ａは外気が流通する中間空気層１３を有したダブルスキン構造である。
前記スパンドレル部１０ｂは、耐火ボードのように耐火性能を有した室内側パネル１６と室外側パネル１７を備え、その室内側パネル１６と室外側パネル１７との間に中間空気層１８を有している。
この中間空気層１８は室外に連通せずに外気が流通しないようにしてスパンドレル部１０ｂは外気が流通する中間空気層を有したダブルスキン構造ではない。これによって、断熱性能を向上できる。
要するに、スパンドレル部１０ｂの室外側パネル１７は、ビジョン部１０ａの室外側窓１２と面外方向（室内外側方向）に面一で、スパンドレル部１０ｂとビジョン部１０ａの室外側面を面一に連続させるものである。 As shown in FIGS. 1 and 2, the curtain wall 10 constituting the outer wall 1a of the building 1 has vision parts (window parts) 10a and spandrel parts 10b alternately in the vertical direction.
The building 1 has a floor 5 in which a floor plate 4 is attached to a building frame 2 via a floor slab 3, and a ceiling 7 in which a ceiling plate 6 is attached to the floor slab 3, and between the floor 5 and the ceiling 7. Is a living space (indoor) 8 of the building 1, and a boundary portion 9 between the upper floor and the lower floor of the building 1 is between the ceiling 7 on the lower floor and the floor 5 on the upper floor.
The vision part 10 a of the curtain wall 10 faces the living space 8, and the spandrel part 9 faces the boundary part 9.
In this embodiment, the vision part 10a is opposed to the peri counter 4a and the ceiling 7, and the spandrel part 10b is opposed to the peri counter 4a on the upper floor.
The vision unit 10 a includes an indoor side window 11 called an inner skin and an outdoor side window 12 called an outer skin, and an intermediate air layer 13 is formed between the indoor side window 11 and the outdoor side window 12.
The intermediate air layer 13 communicates with the outside through an intake port 14 formed in the lower portion and an exhaust port 15 formed in the upper portion, and the vision unit 10a has an outside air flowing through the intermediate air layer 13 so that the outside air flows. This is a double skin structure having a circulating intermediate air layer 13.
The spandrel portion 10b includes an indoor side panel 16 and an outdoor side panel 17 having fire resistance performance like a fireproof board, and an intermediate air layer 18 is provided between the indoor side panel 16 and the outdoor side panel 17. Yes.
The intermediate air layer 18 does not communicate with the outside of the room so that the outside air does not flow, and the spandrel portion 10b does not have a double skin structure having an intermediate air layer through which the outside air flows. Thereby, heat insulation performance can be improved.
In short, the outdoor panel 17 of the spandrel unit 10b is flush with the outdoor window 12 of the vision unit 10a in the out-of-plane direction (inside of the indoor side), and the outdoor side surface of the spandrel unit 10b and the vision unit 10a is flush with each other. Is.

このようであるから、ビジョン部１０ａの中間空気層１３にのみ外気が流通するので、その外気が流通する中間空気層１３の容積が小さい。
したがって、中間空気層１３に流通する外気の量が少なく、吸気口１４、排気口１５を小さくして、吸気口１４、排気口１５を外観上シンプルにすっきりさせることができるから、室外からカーテンウォールを見たときに吸気口１４、排気口１５が目立つことがなく、外観の見栄えが良い。
また、カーテンウォールの横材に吸気口１４、排気口１５を形成するようにしたときに、その吸気口１４、排気口１５を小さくし、部材や部品を低減させるだけでなく熱性能の向上もはかることの横材を小さくすることができるので、コスト安である。 Since it is like this, since external air distribute | circulates only to the intermediate air layer 13 of the vision part 10a, the volume of the intermediate air layer 13 through which the external air distribute | circulates is small.
Therefore, since the amount of outside air flowing through the intermediate air layer 13 is small, the intake port 14 and the exhaust port 15 can be made small, and the intake port 14 and the exhaust port 15 can be simply cleaned in appearance. The intake port 14 and the exhaust port 15 do not stand out when looking at the camera, and the appearance is good.
In addition, when the air inlet 14 and the air outlet 15 are formed in the transverse members of the curtain wall, the air inlet 14 and the air outlet 15 are made smaller, so that not only the members and parts are reduced, but also the thermal performance is improved. Since the cross member for measuring can be made small, the cost is low.
