本発明は、一戸建て住宅をはじめとする各種住宅(建物)の天井裏、屋根裏などに施工される住宅用ダクト管の製造方法、住宅用ダクト管及び住宅用ダクト管同士の連結構造に関するものである。The present invention, the ceiling of various houses (buildings), including single-family homes, a method of manufacturing aresidentialduct tube which is construction such as in the attic, regarding connection structure betweenresidentialduct tube andresidentialduct pipe Is.

一戸建て住宅をはじめとする各種住宅(建物)の天井裏、屋根裏などには、冷・暖房用気体、換気用気体等を流すダクトが配管施工されている。ダクトとして使用される従来のダクト用管は次のようにして製造されていた。図4(a)に示す発泡ウレタン製、他の発泡材料製のブロックAから、円筒ダクトを数個に区画した端面円弧状のダクト部品Bを切り出し、これらダクト部品Bを図4(b)に示すように周方向に連結して円筒状のダクト用管Fにしていた。この場合ダクト部品Bの幅方向一端の連結凸部Cと他端の連結凹部Dとを連結して筒状にし、連結部分Eを接着剤で接着している。  Ducts for flowing air for cooling and heating, gas for ventilation, etc. are installed in the ceiling and attic of various houses (buildings) including single-family houses. A conventional duct tube used as a duct has been manufactured as follows. 4A is cut out from the block A made of urethane foam and other foamed material shown in FIG. 4A, and the end-arc-shaped duct parts B having a plurality of cylindrical ducts are cut out, and these duct parts B are shown in FIG. 4B. As shown, the pipes F were connected in the circumferential direction to form a cylindrical duct pipe F. In this case, the connecting convex part C at one end in the width direction of the duct part B and the connecting concave part D at the other end are connected to form a cylinder, and the connecting part E is bonded with an adhesive.

前記ダクト用管の製造方法と、その製造方法で製造されるダクト用管には次のような課題がある。
(1)ブロックAからダクト部品Bを一つ一つ削り出す必要があるため、ダクト部品Bの製作に多大な労力を要し、材料の無駄も多く、結果的にダクト用管Fがコスト高になる。
(2)完成したダクト用管Fの内周面は、削り出したままの発泡材料がむき出しになっており、内部をエアが通過する際、発泡材料の微細な粉末や、各種有害物質(例えば、フロン、ジクロロメタン、ヘキサン、ベンゼン、トルエン、アセトン、酢酸等)がエアに混ざって室内に排出されてしまい、それらが人体に悪影響を与える。この課題を防止するために内周面にアルミ箔を貼り付けると、その貼り付けに接着剤が使用されるため、内部を通過するエアと共に接着剤に含まれる有害物質も室内に排出されて人体に悪影響を与える。また、アルミ箔の貼り付け作業が面倒である。
(3)ダクト用管Fの内周面を材料を削り出したままの粗面にしておくと、内部を通過するエアの抵抗が大きくなり馬力の大きな送風機が必要になる。馬力の大きな送風機は大型、コスト高になる。
(4)ダクト部品B同士が連結されているため耐外圧強度が弱い。
(5)連結部分Eから暖気や冷気が漏れる虞があり断熱効率が十分ではない。
The manufacturing method of the duct tube and the duct tube manufactured by the manufacturing method have the following problems.
(1) Since it is necessary to cut out the duct parts B from the block A one by one, a great amount of labor is required for the production of the duct parts B, and there is a lot of waste of materials. As a result, the duct pipe F is expensive. become.
(2) The inner peripheral surface of the completed duct tube F is exposed to the foam material that has been cut out. When air passes through the inside, the fine powder of the foam material and various harmful substances (for example, , Freon, dichloromethane, hexane, benzene, toluene, acetone, acetic acid, etc.) are mixed into the air and discharged into the room, which adversely affects the human body. When aluminum foil is pasted on the inner peripheral surface to prevent this problem, an adhesive is used for the pasting. Therefore, harmful substances contained in the adhesive are discharged into the room together with air passing through the inside. Adversely affects. Also, the work of attaching the aluminum foil is troublesome.
(3) If the inner peripheral surface of the duct tube F is a rough surface with the material cut out, the resistance of the air passing through the inside increases, and a blower with high horsepower is required. A large horsepower blower is large and expensive.
(4) Since the duct parts B are connected to each other, the external pressure resistance is weak.
(5) Warm air or cold air may leak from the connecting portion E, and the heat insulation efficiency is not sufficient.

図1の筒2は、発泡材料で一体成型された筒状部材である。筒2の成型に用いられる発泡材料としては、例えばウレタンや発泡スチロール等、任意の発泡材料を用いることができるが、断熱性のある素材を使用することが望ましい。筒2の発泡材料の発泡倍率は例えば原液対比30倍とする等、任意とすることができる。また、発泡後の発泡材料の密度も任意とすることができる。また、この筒2は、蛇腹状に成型して可撓性を備えるものとすることもできる。  Acylinder 2 in FIG. 1 is a cylindrical member integrally formed of a foam material. As a foaming material used for molding thecylinder 2, for example, any foaming material such as urethane or polystyrene foam can be used, but it is desirable to use a heat insulating material. The expansion ratio of the foam material of thetube 2 can be arbitrarily set, for example, 30 times that of the stock solution. Moreover, the density of the foamed material after foaming can also be made arbitrary. Moreover, thiscylinder 2 can be molded into a bellows shape and provided with flexibility.
