1. 1. Configuration of Embodiments FIG. 1 is a perspective view of a state in which space-securing parts according to an embodiment of the present disclosure are installed in a ceiling facility as viewed from the floor side. FIG. 2 is a plan view of a state in which the space-securing parts according to the embodiment of the present disclosure are installed in the ceiling equipment as viewed from the ceiling side. Further, FIG. 3 is a front view of a state in which the space-securing parts according to the embodiment of the present disclosure are installed in the ceiling equipment as viewed from the front side. In these figures, the air conditioner 10 is a ceiling facility installed in the space behind the ceiling. Typically, the air conditioner 10 is suspended from the superstructure 8 of the building skeleton by suspension bolts 12. These figures exemplify the state of the ceiling equipment during the construction period. Peripheral equipment such as ceiling bases, ducts, wiring, and piping have not yet been installed around the air conditioner 10. Also, the ceiling has not been laid yet.

空気調和装置１０は、側面にダクト１４が接続されている。図では、明瞭性を考慮してダクト１４の接続部のみを図視している。空気調和装置１０は、側面に保守用開閉カバー１６を備えている。保守用開閉カバー１６は、横開きの扉として構成されている。図２には、天井を敷設した後に設置される点検口６を図示している。点検を行う作業員は、点検口６から天井裏空間に進入して空気調和装置１０へとアクセスする。保守用開閉カバー１６の内部には、空気調和装置１０の保守点検部品が収容されている。典型的には、空気調和装置１０は、保守点検部品としてフィルタ４を備える。図２では、板状の２枚の縦型のフィルタ４が空気調和装置１０の内部に収容されている。フィルタ４は、保守用開閉カバー１６を開いた開口部から手前に引き出すことに取り外すことができる。 A duct 14 is connected to the side surface of the air conditioner 10. In the figure, only the connection portion of the duct 14 is illustrated in consideration of clarity. The air conditioner 10 is provided with a maintenance opening / closing cover 16 on the side surface. The maintenance opening / closing cover 16 is configured as a side-opening door. FIG. 2 illustrates an inspection port 6 installed after the ceiling is laid. The worker performing the inspection enters the space behind the ceiling from the inspection port 6 and accesses the air conditioner 10. Inside the maintenance opening / closing cover 16, maintenance and inspection parts of the air conditioner 10 are housed. Typically, the air conditioner 10 includes a filter 4 as a maintenance / inspection component. In FIG. 2, two plate-shaped vertical filters 4 are housed inside the air conditioner 10. The filter 4 can be removed by pulling the maintenance opening / closing cover 16 toward the open opening.

ここで、保守用開閉カバー１６を開ける場合及びフィルタ４を引き出す場合、保守用開閉カバー１６の手前に作業用の空間が必要となる。この作業用に必要な空間は、以下「保守スペース」と呼ばれる。配管又はダクト等の周辺設備が保守スペースを通って設置されると、点検口６から天井裏空間へと進入できない、保守用開閉カバー１６を開けることができない、フィルタ４を引き出すことができない、といった不具合が生じるおそれがある。 Here, when opening the maintenance opening / closing cover 16 and pulling out the filter 4, a working space is required in front of the maintenance opening / closing cover 16. The space required for this work is hereinafter referred to as "maintenance space". When peripheral equipment such as pipes or ducts is installed through the maintenance space, it is not possible to enter the space behind the ceiling from the inspection port 6, the maintenance opening / closing cover 16 cannot be opened, and the filter 4 cannot be pulled out. There is a risk of malfunction.

そこで、本実施の形態の保守スペース確保方法は、天井設備の施工期間中において、保守スペースに空間確保部品２０を設置することによって保守スペースに周辺設備が設置されることを防ぐ。図４は、空間確保部品の構成を説明するための図である。空間確保部品２０は、ワイヤーフレーム２２と、メッシュ部材２４と、固定用部材２６と、を備えている。 Therefore, the maintenance space securing method of the present embodiment prevents peripheral equipment from being installed in the maintenance space by installing the space securing component 20 in the maintenance space during the construction period of the ceiling equipment. FIG. 4 is a diagram for explaining the configuration of the space securing component. The space securing component 20 includes a wire frame 22, a mesh member 24, and a fixing member 26.

ワイヤーフレーム２２は、空間確保部品２０の外形の骨格を構成する。典型的には、ワイヤーフレーム２２は、角丸の矩形形状に曲げられた４つのワイヤーフレーム２２の長手方向同士を可動自在に組み合わせることにより、全体として直方体に近い箱型の外郭となるように構成される。また、ワイヤーフレーム２２の長手方向の寸法は、フィルタ４の引き出し方向の奥行寸法よりも長くなるように構成されている。また、ワイヤーフレーム２２の短手方向の寸法は、フィルタ４の引き出し方向に垂直な幅寸法よりも長くなるように構成されている。 The wire frame 22 constitutes the outer skeleton of the space securing component 20. Typically, the wire frame 22 is configured to have a box-shaped outer shell that is close to a rectangular parallelepiped as a whole by movably combining the four wire frames 22 bent into a rectangular shape with rounded corners in the longitudinal directions. Will be done. Further, the dimension in the longitudinal direction of the wire frame 22 is configured to be longer than the depth dimension in the withdrawal direction of the filter 4. Further, the dimension of the wire frame 22 in the lateral direction is configured to be longer than the width dimension perpendicular to the pull-out direction of the filter 4.

メッシュ部材２４は、４つのワイヤーフレーム２２のそれぞれを外形とする面に張られている。メッシュ部材２４は、識別容易な色彩として、例えば黄色に着色されている。また、メッシュ部材２４の材質は、軽量且つ風通しの良いメッシュ構造が望ましい。また、メッシュ部材２４は、４つのワイヤーフレーム２２の短手方向の辺で構成される底面又は天面に張られていてもよい。 The mesh member 24 is stretched on a surface having each of the four wire frames 22 as an outer shape. The mesh member 24 is colored, for example, yellow as an easily identifiable color. Further, the material of the mesh member 24 is preferably a lightweight and well-ventilated mesh structure. Further, the mesh member 24 may be stretched on the bottom surface or the top surface composed of the sides of the four wire frames 22 in the lateral direction.

固定用部材２６は、空間確保部品２０の長手方向を水平に配置した場合に、空間確保部品２０の上面を構成するワイヤーフレーム２２の短手方向の辺から突出するように構成された部材である。図４では、2本の上側ベルト部材が固定用部材２６として設けられている。固定用部材２６としてのベルト部材の本数に限定はない。固定用部材２６が保守用開閉カバー１６の隙間に挟み込まれることにより、空間確保部品２０が空気調和装置１０に固定される。 The fixing member 26 is a member configured to protrude from the side of the wire frame 22 constituting the upper surface of the space securing component 20 in the lateral direction when the space securing component 20 is arranged horizontally in the longitudinal direction. .. In FIG. 4, two upper belt members are provided as fixing members 26. The number of belt members as the fixing member 26 is not limited. The space securing component 20 is fixed to the air conditioner 10 by sandwiching the fixing member 26 in the gap of the maintenance opening / closing cover 16.

次に、空間確保部品２０の具体的な固定方法について説明する。図５は、空間確保部品の取り付け方法の一例を示す図である。なお、図５では、空気調和装置１０に取り付けられた空間確保部品を空気調和装置１０の正面から見た拡大図である。空間確保部品２０は、空気調和装置１０の周辺設備を施工する期間中に設置されるものである。空間確保部品２０の設置工程では、この図に示すように、保守用開閉カバー１６を若干開けた状態で、固定用部材２６としての１又は複数の上側ベルト部材を保守用開閉カバー１６の上辺から裏側に向けて垂れ下げる。そして、保守用開閉カバー１６を完全に閉めることにより、固定用部材２６を挟み込んで固定する。 Next, a specific fixing method of the space securing component 20 will be described. FIG. 5 is a diagram showing an example of a method of attaching a space-securing component. Note that FIG. 5 is an enlarged view of the space securing component attached to the air conditioner 10 as viewed from the front of the air conditioner 10. The space securing component 20 is installed during the period of construction of the peripheral equipment of the air conditioner 10. In the installation process of the space securing component 20, as shown in this figure, with the maintenance opening / closing cover 16 slightly opened, one or a plurality of upper belt members as the fixing member 26 are attached from the upper side of the maintenance opening / closing cover 16. It hangs down toward the back side. Then, by completely closing the maintenance opening / closing cover 16, the fixing member 26 is sandwiched and fixed.

周辺設備の施工中、空間確保部品２０は、空気調和装置１０の保守スペースを周辺設備の設置禁止領域として周囲に認識させるために機能する。周辺設備の施工業者は、空間確保部品２０を避けて周辺設備を施工することにより、空気調和装置１０の保守スペースに誤って周辺設備を設置することを防ぐことができる。 During the construction of the peripheral equipment, the space securing component 20 functions to make the surroundings recognize the maintenance space of the air conditioner 10 as the installation prohibited area of the peripheral equipment. By avoiding the space securing component 20 and constructing the peripheral equipment, the contractor of the peripheral equipment can prevent the peripheral equipment from being mistakenly installed in the maintenance space of the air conditioner 10.

周辺設備の施工が完了すると、空間確保部品２０は取り外される。ここでは、保守用開閉カバー１６を開ける動作によって挟まっていた固定用部材２６が解放される。これにより空間確保部品２０が容易に取り外される。 When the construction of the peripheral equipment is completed, the space securing part 20 is removed. Here, the fixing member 26 sandwiched by the operation of opening the maintenance opening / closing cover 16 is released. As a result, the space securing component 20 is easily removed.

このような空間確保部品２０の構成および固定方法によれば、以下のような作用及び効果が得られる。 According to the configuration and fixing method of the space securing component 20, the following actions and effects can be obtained.

工具等を一切使用することなく、保守用開閉カバー１６の開閉動作によって固定用部材２６を着脱することができる。特に、空気調和装置１０が設置されている場所は高所であるため、作業者は脚立等を使用する必要がある。また、空間確保部品２０を取り外す際には天井が敷設されていることもあるため、天井裏は狭く且つ暗い空間になっている可能性もある。このため、空間確保部品２０を簡易な作業で着脱できる構成は、作業者の負担の軽減に大きく寄与する。 The fixing member 26 can be attached / detached by opening / closing the maintenance opening / closing cover 16 without using any tools or the like. In particular, since the place where the air conditioner 10 is installed is a high place, the operator needs to use a stepladder or the like. Further, since the ceiling may be laid when the space securing component 20 is removed, there is a possibility that the space behind the ceiling is narrow and dark. Therefore, the configuration in which the space securing component 20 can be attached and detached by a simple operation greatly contributes to the reduction of the burden on the operator.

空間確保部品２０は、ワイヤーフレーム２２とメッシュ部材２４で構成されている。このような構成によれば、軽量でありながらも空間確保部品２０の形状を維持することができる。これにより、保守用開閉カバー１６に固定用部材２６を挟み込むだけでも空間確保部品２０を十分に保持することが可能となる。 The space securing component 20 is composed of a wire frame 22 and a mesh member 24. According to such a configuration, the shape of the space securing component 20 can be maintained while being lightweight. As a result, the space securing component 20 can be sufficiently held even by simply sandwiching the fixing member 26 in the maintenance opening / closing cover 16.

メッシュ部材２４は、空間確保部品２０を周囲から認識し易くするために貢献する。特に、メッシュ部材２４が黄色等の目立つ色彩に着色されることにより、更に識別度を高めることができる。また、メッシュ素材は風を通すため、風に煽られて空間確保部品２０が外れる可能性を減らすことができる。 The mesh member 24 contributes to make it easier for the space securing component 20 to be recognized from the surroundings. In particular, the mesh member 24 is colored in a conspicuous color such as yellow, so that the degree of discrimination can be further enhanced. Further, since the mesh material allows air to pass through, it is possible to reduce the possibility that the space securing component 20 will come off due to the wind.

空間確保部品２０は、長手方向及び短手方向の寸法がそれぞれフィルタ４の奥行方向及び幅方向の寸法よりも長い。このような空間確保部品２０によれば、フィルタ４を確実に引き出し可能な範囲が空間確保部品２０によって確保される。 The space-securing component 20 has dimensions in the longitudinal direction and the lateral direction longer than the dimensions in the depth direction and the width direction of the filter 4, respectively. According to such a space securing component 20, a range in which the filter 4 can be reliably pulled out is secured by the space securing component 20.

４．変形例
本実施の形態の空間確保部品２０を用いた保守スペース確保方法は、以下のように変形した態様を適用してもよい。 4. Modification example As the maintenance space securing method using the space securing component 20 of the present embodiment, the modified mode as follows may be applied.

４－１．空間確保部品２０
空間確保部品２０は平面状に折り畳み可能に構成されていてもよい。図６は、折り畳んだ状態の空間確保部品の一例を示す図である。この図に示す空間確保部品２０は、直方体の短手方向の対角方向に長手方向の辺を押し込むことにより、４つのワイヤーフレーム２２が重なるように折り畳むことができる。このような構成によれば、取り付け場所まで空間確保部品２０を容易に持ち運ぶことができる。また、空間確保部品２０を空気調和装置１０から取り外した後に折り畳むこととすれば、空間確保部品２０を狭い点検口６から取り出すことが容易となる。 4-1. Space securing parts 20
The space securing component 20 may be configured to be foldable in a plane. FIG. 6 is a diagram showing an example of a space-securing part in a folded state. The space-securing component 20 shown in this figure can be folded so that the four wire frames 22 overlap each other by pushing the sides in the longitudinal direction in the diagonal direction in the lateral direction of the rectangular parallelepiped. According to such a configuration, the space securing component 20 can be easily carried to the mounting place. Further, if the space securing component 20 is folded after being removed from the air conditioner 10, the space securing component 20 can be easily taken out from the narrow inspection port 6.

空間確保部品２０は、保守スペースを占有し得る形状であれば、箱型に限らず種々の形状を採用し得る。 The space securing component 20 is not limited to the box shape and may adopt various shapes as long as it has a shape that can occupy the maintenance space.

４－２．固定用部材２６
４－２―１．第一変形例
固定用部材２６は、保守用開閉カバー１６の下辺側にも挟まるように構成されていてもよい。図７は、空間確保部品の第一変形例を示す図である。また、図８は、第一変形例の空間確保部品を空気調和装置に取り付けた状態を正面側から見た図である。これらの図に示すように、第一変形例の空間確保部品２０は、保守用開閉カバー１６の縦寸法よりも長い２本の上側ベルト部材によって構成された固定用部材２６ａを有している。 4-2. Fixing member 26
4-2-1. First Modification Example The fixing member 26 may be configured to be sandwiched between the lower side of the maintenance opening / closing cover 16. FIG. 7 is a diagram showing a first modification example of the space securing component.
