Description

本発明は、建物内に構築される天井面の裏側（天井裏領域）に配置され、空調メインダクトから供給される空調空気を、天井面に設置された空調用吹出口へ分配する空調用チャンバーの設置技術に関する。   The present invention is an air conditioning chamber that is arranged on the back side (ceiling area) of a ceiling surface constructed in a building and distributes conditioned air supplied from an air conditioning main duct to air conditioning outlets installed on the ceiling surface. Related to the installation technology.

建物内の天井裏領域に配設される空調用チャンバーの設置技術については、従来、様々な方式が提案されているが、本発明に関連するものとして、例えば、特許文献１記載の「空気調和用チャンバー支持構造」がある。   Various methods have conventionally been proposed for installing an air-conditioning chamber disposed in a ceiling area in a building. For example, as related to the present invention, for example, “Air Conditioning” described in Patent Document 1 Chamber support structure ".

この「空気調和用チャンバー支持構造」は、略Ｌ字状体の吊り金具をチャンバーの側面に開設された貫通孔に通して配設し、この吊り金具を、天井躯体から室内空間側に向けて略垂直に吊り下げられた吊下げボルトの端部に固定するというものである。   This “air conditioning chamber support structure” has a substantially L-shaped suspension fitting placed through a through-hole formed in the side surface of the chamber, and the suspension fitting is directed from the ceiling housing to the indoor space side. It is fixed to the end of a suspension bolt that is suspended substantially vertically.

登録実用新案第３０６０４２３号公報Registered Utility Model No. 3060423

特許文献１記載の「空気調和用チャンバー支持構造」は天井躯体から室内空間側に向けて略垂直に吊り下げられた吊下げボルトを利用して空気調和用チャンバーを支持するものであるため、複数の吊下げボルトを天井躯体に打設して固定する工事が必要である。また、この打設工事においては、吊下げボルトにて支持される空気調和用チャンバーの吊金具の貫通孔に合わせて位置決めを行って、吊下げボルトを施工する必要があるため、空気調和用チャンバーの配置設計および吊下げボルトの施工が面倒である。   The “air conditioning chamber support structure” described in Patent Document 1 supports the air conditioning chamber using a suspension bolt that is suspended substantially vertically from the ceiling housing toward the indoor space. It is necessary to install a hanging bolt on the ceiling frame and fix it. In addition, in this installation work, it is necessary to position the air conditioning chamber according to the through hole of the suspension fitting of the air conditioning chamber supported by the suspension bolt and install the suspension bolt. The layout design and construction of the suspension bolts are troublesome.

また、建物の天井裏空間には空調ダクトや照明その他の設備が配置されているので、他の機器との取り合いの関係上、施工後の吊下げボルトの位置変更は、まず不可能である。さらに、改修工事においても、新たに設置する空気調和用チャンバーごとに、吊下げボルトの位置決めおよび施工が発生し、多大な労力と時間を要するため、空調改修工事に容易に対応することができない。   In addition, since air conditioning ducts, lighting, and other equipment are arranged in the ceiling space of the building, it is impossible to change the position of the suspension bolt after construction because of the relationship with other equipment. Further, even in the renovation work, the positioning and construction of the suspension bolts are required for each newly installed air conditioning chamber, which requires a great deal of labor and time, and therefore cannot easily cope with the air conditioning renovation work.

そこで、本発明が解決しようとする課題は、施工が容易で、空調改修工事に容易に対応することができ、安全性にも優れた空調用チャンバー設置構造を提供することにある。   Therefore, the problem to be solved by the present invention is to provide an air-conditioning chamber installation structure that is easy to construct, can easily cope with air-conditioning repair work, and is excellent in safety.

本発明に係る空調用チャンバー設置構造は、建物内に天井を構築するため複数のＴバーを配置して形成されたシステム天井と、前記システム天井の少なくとも一つの区画を形成する前記Ｔバー上に載置される（若しくは前記Ｔバーで形成された区画内に配置される）空調用チャンバーと、前記Ｔバーに係合することにより前記空調用チャンバーを前記Ｔバーに固定するため前記空調用チャンバーに付設された固定具と、を備えたことを特徴とする。   The air-conditioning chamber installation structure according to the present invention includes a system ceiling formed by arranging a plurality of T bars for constructing a ceiling in a building, and the T bar forming at least one section of the system ceiling. An air conditioning chamber to be placed (or placed in a section formed by the T bar) and the air conditioning chamber to engage the T bar to fix the air conditioning chamber to the T bar. And a fixing tool attached to the head.

このような構成とすれば、建物の躯体に固着される吊ボルトを使用することなく、Ｔバー上に載置するだけで空調用チャンバーを天井裏領域に設置することが可能となるので、空調用チャンバーの施工が容易となり、空調改修工事にも容易かつ好適に対応することができる。空調用チャンバーは、Ｔバーに係合する固定具によってＴバーに一体的に固定されるので、地震発生時にズレたり、外れたりせず、安全性にも優れている。   With such a configuration, the air conditioning chamber can be installed in the ceiling back area simply by placing it on the T-bar without using the suspension bolts fixed to the building frame. This makes it easy to construct the chamber for the air conditioner and can easily and suitably cope with the air conditioning renovation work. Since the air-conditioning chamber is integrally fixed to the T-bar by a fixture that engages with the T-bar, it does not shift or come off when an earthquake occurs, and is excellent in safety.

ここで、前記固定具は、前記Ｔバーを天井裏側から弾性的に把持可能なクリップ部を有することが望ましい。   Here, it is preferable that the fixture has a clip portion that can elastically grip the T-bar from the ceiling back side.

このような構成とすれば、Ｔバーに対する固定具による係止作業が容易となるので、施工性の向上に有効であり、地震発生時の落下防止機能も向上する。   With such a configuration, the locking operation with the fixing member to the T-bar becomes easy, which is effective for improving workability and also improves the fall prevention function when an earthquake occurs.

一方、前記空調用チャンバーを、不燃性の金属箔が両面に貼着された段ボール材で形成することもできる。   On the other hand, the air-conditioning chamber may be formed of a corrugated cardboard material in which a nonflammable metal foil is stuck on both sides.

このような構成とすれば、従来の金属製の空調用チャンバーに比べ、軽量化されるので、施工作業の負荷が軽減し、安全な施工が実現できる。また、地震発生時などに、万一、空調用チャンバーがシステム天井から脱落して、室内側へ落下することがあっても、空調用チャンバー自体が軽量なので、重大事故を回避することができ、安全性も向上する。また、段ボール材は金属材料より断熱性に優れているため、空調用チャンバー全体の断熱性を高めることができ、別途、保温施工などが不要となり、空調エネルギーの無駄を軽減することができる。   With such a configuration, the weight is reduced compared to a conventional metal air-conditioning chamber, so the load of construction work is reduced and safe construction can be realized. Also, even if an air conditioning chamber falls off the system ceiling and falls indoors in the event of an earthquake, etc., a serious accident can be avoided because the air conditioning chamber itself is lightweight. Safety is also improved. In addition, since the corrugated board material has better heat insulation than the metal material, the heat insulation of the entire air conditioning chamber can be improved, and no additional heat insulation work is required, thereby reducing waste of air conditioning energy.

本発明により、施工が容易で、空調改修工事に容易に対応することができ、安全性にも優れた空調用チャンバー設置構造を提供することができる。   According to the present invention, it is possible to provide an air-conditioning chamber installation structure that is easy to construct, can easily cope with air-conditioning repair work, and is excellent in safety.

以下、図１〜図８に基づいて、本発明の実施形態である空調用チャンバー設置構造１００及びその施工方法などについて説明する。   Hereinafter, based on FIGS. 1-8, the air-conditioning chamber installation structure 100 which is embodiment of this invention, its construction method, etc. are demonstrated.

図１に示すように、本実施形態の空調用チャンバー設置構造１００は、建物内に天井を構築するため複数のＴバー１１を格子状に配置して形成されたシステム天井の１種であるグリッド天井１０と、グリッド天井１０の少なくとも一つの区画を形成するＴバー１１上に載置される空調用チャンバー２０と、Ｔバー１１に係合することにより空調用チャンバー２０をＴバー１１に固定するため空調用チャンバー２０に付設された複数の固定具３０と、を備えている。   As shown in FIG. 1, the air-conditioning chamber installation structure 100 according to the present embodiment is a grid that is a type of system ceiling formed by arranging a plurality of T bars 11 in a lattice shape in order to construct a ceiling in a building. The air conditioning chamber 20 is fixed to the T bar 11 by engaging the ceiling 10, the air conditioning chamber 20 placed on the T bar 11 forming at least one section of the grid ceiling 10, and the T bar 11. Therefore, a plurality of fixtures 30 attached to the air conditioning chamber 20 are provided.

本実施形態においては、グリッド天井１０の１区画の寸法は６００ｍｍ×６００ｍｍとしており、空調用チャンバー２０は、前記１区画の寸法よりも一回り小さい寸法としている。なお、グリッド天井１０の区画寸法は６００ｍｍ×６００ｍｍのほか、６４０ｍｍ×６４０ｍｍという規格もある。   In the present embodiment, the size of one section of the grid ceiling 10 is set to 600 mm × 600 mm, and the air conditioning chamber 20 is set to be slightly smaller than the size of the one section. In addition, the partition dimensions of the grid ceiling 10 include a standard of 640 mm × 640 mm in addition to 600 mm × 600 mm.

図２〜図５に示すように、空調用チャンバー２０は、直方体形状をしたケーシング２１と、ケーシング２１の正面部２１ａに開設された空気流入口２２と、ケーシング２１の側面部２１ｂに開設された複数の空気流出口２３と、ケーシング２１の底面部２１ｃの前縁部２１ｄ及び後縁部２１ｅにそれぞれ垂下状に付設された固定具３０と、を備えている。   As shown in FIGS. 2 to 5, the air-conditioning chamber 20 is formed in a rectangular parallelepiped casing 21, an air inlet 22 opened in the front part 21 a of the casing 21, and a side part 21 b of the casing 21. A plurality of air outlets 23, and fixtures 30 attached to the front edge portion 21 d and the rear edge portion 21 e of the bottom surface portion 21 c of the casing 21 in a hanging manner, respectively.

ケーシング２１の正面部２１ａの空気流入口２２は、空調メインダクトから分岐したダクト（図示せず）と接続するための開口部であり、ケーシング２１の側面部２１ｂの複数の空気流出口２３は、別途、天井に設置された空調用吹出口とフレキシブルダクトなどの任意の手段によって接続するための開口部である。   The air inlet 22 of the front part 21a of the casing 21 is an opening for connecting to a duct (not shown) branched from the air conditioning main duct, and the plurality of air outlets 23 of the side part 21b of the casing 21 are: Separately, it is an opening for connecting to an air-conditioning outlet provided on the ceiling by an arbitrary means such as a flexible duct.

空調用チャンバー２０のケーシング２１は、不燃性の金属箔が両面に貼着された平板状の段ボール材の複数枚を組み合わせて直方体形状（六面体形状）とし、各段ボール材の辺縁部同士の接合部分にアルミテープを貼着することによって形成されている。   The casing 21 of the air conditioning chamber 20 is formed into a rectangular parallelepiped shape (hexahedral shape) by combining a plurality of flat cardboard materials each having a non-combustible metal foil adhered to both surfaces, and the edges of the corrugated cardboard materials are joined to each other. It is formed by sticking aluminum tape on the part.

図３に示すように固定具３０は、空調用チャンバー２０のケーシング２１の底面部２１ｃの前縁部２１ｄ及び後縁部２１ｅから垂下する舌片状の支持部３１と、支持部３１の外面に固着された複数のクリップ部３２と、を備えている。   As shown in FIG. 3, the fixture 30 is provided with a tongue-like support portion 31 that hangs down from the front edge portion 21 d and the rear edge portion 21 e of the bottom surface portion 21 c of the casing 21 of the air conditioning chamber 20, and A plurality of fixed clip portions 32.

クリップ部３２において断面Ｌ字状をなす上半部分３２ａは支持部３１の外面に固着され、クリップ部３２において断面Ｊ字状をなす下半部分３２ｂは支持部３１の下半部分３１ｂの外面との間に隙間Ｇ（図８参照）を隔てた状態に配設されている。本実施形態においては、支持部３１が鉄板材で形成され、クリップ部３２はバネ材で形成されている。後述するように、固定具３０において、クリップ部３２の下半部分３２ｂと、支持部３１の下半部分３１ｂと、の間に形成された隙間Ｇに、グリッド天井１０のＴバー１１を天井裏側から弾性的に把持可能である。   An upper half portion 32a having an L-shaped cross section in the clip portion 32 is fixed to the outer surface of the support portion 31, and a lower half portion 32b having a J shape in the clip portion 32 is connected to the outer surface of the lower half portion 31b of the support portion 31. Are arranged with a gap G (see FIG. 8) therebetween. In this embodiment, the support part 31 is formed with an iron plate material, and the clip part 32 is formed with a spring material. As will be described later, in the fixture 30, the T-bar 11 of the grid ceiling 10 is placed on the back side of the ceiling G in the gap G formed between the lower half portion 32 b of the clip portion 32 and the lower half portion 31 b of the support portion 31. It can be gripped elastically.

次に、図６〜図８を参照しながら、図１に示す空調用チャンバー設置構造１００の施工方法などについて説明する。   Next, a construction method of the air-conditioning chamber installation structure 100 shown in FIG. 1 will be described with reference to FIGS.

図６に示すように、複数のＴバー１１を格子状に配置して形成されたグリッド天井１０に対し、その室内側からグリッド天井１０上方の天井裏まで空調用チャンバー２０を搬入する。この場合、空調用チャンバー２０はグリッド天井１０の１区画より一回り小さい寸法で形成されているため、格子状のＴバー１１によって形成された複数の区画のうち、未だ天井材１２が取り付けられていない区画１３を経由して、空調用チャンバー２０を天井裏まで搬入することができる。この搬入作業は、空調用チャンバー２０を、その正面部２１ａを真上に向け、背面部２１ｆ（図４参照）を真下に向けた姿勢に保ちながら、区画１３の直下から天井裏領域に向かって垂直に持ち上げることによって行われる。   As shown in FIG. 6, the air conditioning chamber 20 is carried from the indoor side to the back of the ceiling above the grid ceiling 10 with respect to the grid ceiling 10 formed by arranging a plurality of T bars 11 in a grid pattern. In this case, since the air conditioning chamber 20 is formed with a size slightly smaller than one section of the grid ceiling 10, the ceiling material 12 is still attached among the plurality of sections formed by the lattice-shaped T-bar 11. The air-conditioning chamber 20 can be carried into the ceiling via the no section 13. This carry-in operation is performed from the position immediately below the compartment 13 toward the ceiling back area while keeping the air-conditioning chamber 20 in a posture in which the front surface portion 21a is directly above and the back surface portion 21f (see FIG. 4) is directly below. This is done by lifting vertically.

空調用チャンバー２０が天井裏まで搬入されたら、図７に示すように、空調用チャンバー２０を本来の設置姿勢（底面部２１ｃを下方に向けた姿勢）にするとともに、空調用チャンバー２０の設置予定場所である、天井材１２の取り付けが完了している区画１４上まで空調用チャンバー２０を移動させる。この後、空調用チャンバー２０を区画１４に向かって下降させると、図８に示すような工程を経て、空調用チャンバー２０の固定具３０が天井裏側からＴバー１１に係合し、Ｔバー１１を把持することによって、空調用チャンバー２０がＴバー１１に固定される。   When the air conditioning chamber 20 is carried to the back of the ceiling, as shown in FIG. 7, the air conditioning chamber 20 is brought to the original installation posture (the posture in which the bottom surface portion 21 c is directed downward) and the air conditioning chamber 20 is scheduled to be installed. The air-conditioning chamber 20 is moved to the location, which is the section 14 where the installation of the ceiling material 12 is completed. Thereafter, when the air conditioning chamber 20 is lowered toward the section 14, the fixture 30 of the air conditioning chamber 20 is engaged with the T bar 11 from the back of the ceiling through the process shown in FIG. , The air conditioning chamber 20 is fixed to the T-bar 11.

詳しくは、図８（ａ）に示すように、Ｔバー１１の縦断面形状は、中央部分が括れた鉄道レールの断面形状に近似した形状をしており、クリップ部３２は弾性変形可能であるので、図８（ｂ）に示すように、空調用チャンバー２０を下降させると、支持部３１の外面がＴバー１１に摺接してガイドとして機能しつつ、固定具３０の空隙Ｇの部分が天井裏側からＴバー１１の上縁部１１ａに向かって押圧され、クリップ部３２が外側に弾性変形しながら空隙Ｇが開いていき、空隙Ｇ内にＴバー１１の上縁部１１ａの一部が嵌入した状態となる。   Specifically, as shown in FIG. 8 (a), the vertical cross-sectional shape of the T-bar 11 has a shape that approximates the cross-sectional shape of the railroad rail with the center portion constricted, and the clip portion 32 can be elastically deformed. Therefore, as shown in FIG. 8B, when the air conditioning chamber 20 is lowered, the outer surface of the support portion 31 is in sliding contact with the T-bar 11 and functions as a guide, while the gap G of the fixture 30 has a ceiling. The gap G is opened from the back side toward the upper edge 11a of the T bar 11 and the clip part 32 is elastically deformed outward, and a part of the upper edge 11a of the T bar 11 is inserted into the gap G. It will be in the state.

この後、さらに、空調用チャンバー２０を下降させると、クリップ部３２がさらに弾性変形して空隙Ｇが一旦大きく開いて、Ｔバー１１の上縁部１１ａ全体が空隙Ｇ内に嵌り込んだ後、クリップ部３２が元の状態に復元し、固定具３０がＴバー１１の上縁部１１ａを把持した状態となるので、空調用チャンバー２０がＴバー１１に固定される。この後、区画１３に天井材１２を取り付けると、図１に示す状態となる。   Thereafter, when the air conditioning chamber 20 is further lowered, the clip portion 32 is further elastically deformed and the gap G is once greatly opened. After the entire upper edge portion 11a of the T bar 11 is fitted in the gap G, Since the clip portion 32 is restored to the original state and the fixture 30 is in a state of gripping the upper edge portion 11a of the T bar 11, the air conditioning chamber 20 is fixed to the T bar 11. Thereafter, when the ceiling member 12 is attached to the section 13, the state shown in FIG.

この後、空調メインダクトから分岐した分岐ダクト（図示せず）と空気流入口２２を接続し、並びに、天井に設置した空調用吹出口（図示せず）と空気流出口２３とをフレキシブルダクトなど（図示せず）を用いて接続すると、空調メインダクトから送給される空調空気を空調用チャンバー２０において各空調用吹出口へ分配し、被空調対象空間へ空調空気を供給することができる。   Thereafter, a branch duct (not shown) branched from the air conditioning main duct and the air inlet 22 are connected, and an air outlet (not shown) installed on the ceiling and the air outlet 23 are connected to a flexible duct or the like. When connected by using (not shown), the conditioned air supplied from the air-conditioning main duct can be distributed to the air-conditioning outlets in the air-conditioning chamber 20, and the conditioned air can be supplied to the air-conditioned space.

図１に示すように、本実施形態の空調用チャンバー設置構造１００は、建物の躯体に固着される吊ボルトを使用しないので、空調用チャンバー２０の施工が容易となり、空調改修工事にも容易かつ好適に対応することができる。空調用チャンバー２０は、Ｔバー１１を把持する固定具３０によってＴバー１１に一体的に固定されるので、地震発生時にズレたり、外れたりせず、安全性にも優れている。   As shown in FIG. 1, the air conditioning chamber installation structure 100 of the present embodiment does not use suspension bolts that are fixed to the building frame. It can respond suitably. The air-conditioning chamber 20 is integrally fixed to the T-bar 11 by the fixture 30 that holds the T-bar 11, so that it does not shift or come off when an earthquake occurs, and is excellent in safety.

固定具３０は、Ｔバー１１を天井裏側から弾性的に把持可能なクリップ部３２を有するので、Ｔバー１１に対する固定具３０による係止作業は容易であり、施工性の向上に有効であり、地震発生時に優れた落下防止機能を発揮する。   Since the fixture 30 has a clip portion 32 that can elastically hold the T bar 11 from the back side of the ceiling, the locking operation by the fixture 30 with respect to the T bar 11 is easy, and is effective for improving workability. Excellent fall prevention function in the event of an earthquake.

空調用チャンバー２０のケーシング２１は、不燃性の金属箔が両面に貼着された複数の平板状の段ボール材で形成されているので、空調用チャンバー２０が軽量化され、施工性が向上する。また、地震発生時などに、万一、空調用チャンバー２０が落下することがあっても、ケーシング２１自体が軽量なので、重大事故を回避することができ、安全性も向上する。また、不燃性の金属箔が両面に貼着された段ボール材は金属材料より断熱性に優れているため、空調用チャンバー２０全体の断熱性を高めることができ、空調エネルギーの無駄を軽減することができる。   Since the casing 21 of the air-conditioning chamber 20 is formed of a plurality of flat corrugated cardboard materials in which nonflammable metal foils are adhered to both surfaces, the air-conditioning chamber 20 is reduced in weight and workability is improved. Further, even if the air conditioning chamber 20 is dropped in the event of an earthquake, the casing 21 itself is lightweight, so that a serious accident can be avoided and safety is improved. In addition, the corrugated cardboard with the non-combustible metal foil adhered to both sides has better heat insulation than the metal material, so that the heat insulation of the entire air conditioning chamber 20 can be improved and waste of air conditioning energy can be reduced. Can do.

また、本実施形態の固定具３０は金属材料で形成されているが、これに限定するものではないので、金属材料に比べ熱伝導性が低い合成樹脂材で固定具３０を形成することもできる。この場合、冷房運転中に、空調用チャンバー２０から固定具３０を介してＴバー１１へ冷気が伝わることを防止することができる。   Moreover, although the fixture 30 of this embodiment is formed with the metal material, since it is not limited to this, the fixture 30 can also be formed with the synthetic resin material whose heat conductivity is low compared with a metal material. . In this case, it is possible to prevent cold air from being transmitted from the air conditioning chamber 20 to the T-bar 11 via the fixture 30 during the cooling operation.

また、固定具３０は金属製のＴバー１１を把持した状態でＴバー１１に接触しているので、固定具３０を合成樹脂製とすれば、空調運転中に空調空気が空調用チャンバー２０内を流動することに起因して発生する音や振動の天井への伝搬を抑制することができるだけでなく、空調用チャンバー２０とＴバー１１との間の電気的な絶縁性も確保することができる。さらに、室内への振動、音の伝播を防止するため、固定具３０とＴバー１１との間に適宜クッション材や制振材などを挟み込むことも可能である。   Further, since the fixture 30 is in contact with the T-bar 11 while holding the metal T-bar 11, if the fixture 30 is made of synthetic resin, the conditioned air is transferred into the air-conditioning chamber 20 during the air-conditioning operation. It is possible not only to suppress the propagation of sound and vibration generated due to flowing through the ceiling to the ceiling, but also to ensure electrical insulation between the air conditioning chamber 20 and the T-bar 11. . Furthermore, in order to prevent vibrations and sound from being propagated into the room, a cushioning material, a damping material, or the like can be appropriately sandwiched between the fixture 30 and the T-bar 11.

また、固定具３０の空調用チャンバー２０への固定方法についても、本実施形態に限定されるものではなく、空調用チャンバー２０に接着剤あるいは粘着テープで固定する方法を採用したり、鉄板製の空調用チャンバーの場合はビス留めなどの方法にて固定したりすることもできる。   Further, the fixing method of the fixing device 30 to the air conditioning chamber 20 is not limited to this embodiment, and a method of fixing the fixing device 30 to the air conditioning chamber 20 with an adhesive or an adhesive tape may be adopted, In the case of an air conditioning chamber, it can be fixed by a method such as screwing.

さらに、空調用チャンバー２０の設置場所となる天井構造もグリッド天井１０に限定しないので、Ｔバー１１をライン状に配置して天井を構成したシステム天井においても空調用チャンバー２０を設置することができる。   Further, since the ceiling structure as the installation location of the air conditioning chamber 20 is not limited to the grid ceiling 10, the air conditioning chamber 20 can be installed even in a system ceiling in which the T bars 11 are arranged in a line to configure the ceiling. .

一方、空調用チャンバーのケーシングについては、前述したもののほか、組立、分解可能なフレーム部材と、このフレーム部材全体を外面から被覆する被覆部材と、によって構成することもできる。この場合、フレーム部材の被覆部材としては、柔軟性のある布状のものが好適であり、例えば、キャンバス生地、スチールウール製の生地などの不燃性の布または合成繊維などを用いることができる。このような構成とすれば、フレーム部材及び被覆部材などを施工現場に搬入し、現地にて空調用チャンバーの組立作業を行うことが可能となるので、施工現場への搬送性が向上するだけでなく、軽量な空調用チャンバーを構成することができる。   On the other hand, the casing of the air-conditioning chamber can be constituted by a frame member that can be assembled and disassembled and a covering member that covers the entire frame member from the outer surface in addition to the above-described one. In this case, a flexible cloth-like member is suitable as the covering member of the frame member. For example, a non-combustible cloth such as canvas cloth or steel wool cloth or synthetic fiber can be used. With such a configuration, it is possible to carry frame members, covering members, etc. into the construction site and assemble the air conditioning chamber at the site, which improves the transportability to the construction site. And a lightweight air-conditioning chamber can be configured.
