［産業上の利用分野］
本発明は空調機器の分野に利用される。本発明は、断熱
効果に優れ、施工も容易な断熱ダクトに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is utilized in the field of air conditioning equipment. The present invention relates to a heat insulating duct which has an excellent heat insulating effect and is easy to construct.
［従来技術］
建物内の空調を行う冷暖房装置と各部屋とをつなぐため
にダクトが使用されている。従来のダクトは、亜鉛鉄板
などを車に角筒状に形成したもので、空調路の天井部に

は、断熱のためにグラスウールシートが巻き付けられて
いるものである。[Prior Art] Ducts are used to connect each room to an air-conditioning device that performs air conditioning in a building. Conventional ducts are made of galvanized iron plates formed into a rectangular cylindrical shape on the car. They are hung from the ceiling of the air conditioning channel with hanging bolts and piped to each room, and a glass wool sheet is placed on the outside of the duct for insulation. is wrapped around it.
［本発明が解決しようとする問題点］ しかし、従来のダクトには次のような問題点があった。[Problems to be solved by the present invention] However, conventional ducts have the following problems.
（ａ） グラスウールシートはダクトが吊設された
後に巻き付けられるが、ダクトと天井スラブとの間の部

工に時間がかかり、被覆が十分でない箇所が生じやすい
。(a) Glass wool sheets are wrapped around the duct after it is suspended, but it is difficult to wrap the area between the duct and the ceiling slab or the bent part of the duct, and it takes a long time to install. There are likely to be areas where it is insufficient.
（ｂ） グラスクールシートは安価で、断熱材のなか
では施工がしやすいので広く利用されているが、例えば
断熱材として一般的な発泡樹脂はど断熱効果が高くはな
い。このため、冷暖房機器からの距離によって室温が異
なり、機能的に十分とはいえない。(b) Glass cool sheets are widely used because they are cheap and easy to install among insulation materials; however, they do not have a high insulation effect compared to, for example, foamed resin, which is a common insulation material. For this reason, the room temperature varies depending on the distance from the air conditioning equipment, and it cannot be said to be functionally sufficient.
（Ｃ） 冷房時にはダクト外壁に結露するが、ダクト
外壁はグラスクールシートで被覆されており、風通しが
悪いため水分が蒸発しにくく、ダクトの結露箇所に錆が
生じやすい。(C) During cooling, dew condensation occurs on the outer wall of the duct, but since the outer wall of the duct is covered with a glass cool sheet, the ventilation is poor, making it difficult for moisture to evaporate, making it easy for rust to form at the condensation points on the duct.
［問題点を解決するための手段］
上記問題点を解決するために講じた本発明の手段は次の
通りである。即ち本発明は、ダクトの内壁に断熱層を設
けた断熱ダクトである。[Means for solving the problems] The means of the present invention taken to solve the above problems are as follows. That is, the present invention is a heat insulating duct in which a heat insulating layer is provided on the inner wall of the duct.
断熱層は、通常発泡ウレタンなどの発泡樹脂が使用され
、各種方法でダクト内面に設けられる。The heat insulating layer is usually made of foamed resin such as foamed urethane, and is provided on the inner surface of the duct using various methods.
例えば、スプレーガンで発泡樹脂を吹き付けて付着させ
る方法、或は発泡ウレタン板、発泡スチロール板、スタ
イロフォーム板等の発泡樹脂板を貼り付ける方法などが
ある。For example, there is a method of spraying foamed resin with a spray gun to attach it, or a method of pasting a foamed resin board such as a foamed urethane board, a foamed polystyrene board, a styrofoam board, etc.
また、断熱ダクトの製造方法についていえば、通常は、
まずダクトを形成する板体、例えば鉄板に、上記した各
方法で断熱層を設け、鉄板の折曲部分の断熱層にＶ字溝

トに形成する。Also, when it comes to the manufacturing method of insulated ducts, usually
First, a heat insulating layer is provided on the plate that forms the duct, such as a steel plate, using each of the methods described above, a V-shaped groove is provided in the heat insulating layer at the bent part of the steel plate, and the steel plate is bent toward the heat insulating layer to form a rectangular cylindrical heat insulating layer. Form into a duct.
しかし本発明は、これに限定されるものではなく、例え

ソシアネートをコンプレッサで別々にスプレーガンに送

化学反応を起こさせ、断熱層を形成する方法をあげるこ
とができる。However, the present invention is not limited to this. For example, the duct can be manufactured by first bending an iron plate to form a duct, and then applying a heat insulating layer to the inner wall of the duct using a spray gun or the like. An example of this is a method in which polyol and isocyanate are sent separately to a spray gun using a compressor, and simultaneously sprayed onto the iron plate from the nozzle of the spray gun to cause a chemical reaction and form a heat insulating layer.
なお、断熱層の厚さは施工場所の条件に応じて適宜に決

抵抗がないようにするのがよく、望ましくは、更に断熱
層の表面に、表面が平滑な合成樹脂シートを貼り付ける

を軽減するようにするのがよい。Note that the thickness of the heat insulating layer is appropriately determined depending on the conditions of the construction site. In addition, the surface of the heat insulating layer should be as uneven as possible so that there is no resistance to air blowing, and preferably, a synthetic resin sheet with a smooth surface should be pasted on the surface of the heat insulating layer to prevent air blowing. It is better to reduce the resistance and reduce the power required for blowing air.
