21 : 삽입홈21: insertion groove

본 고안은 공기덕트의 개량에 관한 것이며, 특히 합성수지 필름의 외면에 알루미늄 박막이 피막된 테이프를 나선관 형태로 하고, 각 이음새를 강선과모양의 삽입홈을 가진 합성수지제 결속 밴드로 견고하게 접속하고 그 내면에 단열재가 접합된 새로운 공기 덕트에 관한 것이다.The present invention relates to the improvement of the air duct, and in particular, a tape having a thin aluminum film coated on the outer surface of the synthetic resin film in the form of a spiral tube, and each seam The present invention relates to a new air duct that is firmly connected with a synthetic resin binding band having an insertion groove of a shape and an insulation is bonded to an inner surface thereof.

외부의 신선한 공기를 실내측으로 도입하거나, 혼탁한 실내공기를 건물밖으로 내보내거나, 혹은 냉.난방용 냉.온류를 유통시키는 등의 목적으로 설치되는 공기덕트에 있어서, 종래에는 건축물 등의 설비에 맞춰 판금가공 혹은 대체로 비교적 내경이 큰 금속 또는 합성수지제 관을 사용해 제작한 것이 주종을 이루고 있다. 그러나, 상기 예시의 종래 공기덕트는, 판금가공제인 경우에는 높은 수준의 제작기술이 요구되고, 운반 및 보관성 그리고 부식성등의 면에서 불리하며, 증량감 때문에 현장시공에 많은 어려움이 뒤따를 뿐아니라 경제적으로도 상당히 불리하다.An air duct installed for the purpose of introducing outside fresh air into the interior, discharging cloudy indoor air out of a building, or circulating cold and hot air for heating and cooling. The main predominance is the processing or manufacturing of metal or synthetic pipes with relatively large inner diameters. However, the conventional air duct of the above example, in the case of sheet metal processing agent requires a high level of manufacturing technology, disadvantages in terms of transport and storage properties and corrosiveness, as well as a lot of difficulties in the field construction due to the increased weight. It is also very economically disadvantageous.

금속관제 공기덕트의 경우에는 상기한 결점외에 특히 원하는 형태로의 시공 예를들면, 직각, 예각, 둔각 등의 굴곡시공과 곡선처리가 여의치 못하며, 이러한 시공에 있어서는 특히 이음새 마감이 복잡하고 엄밀해야 하는 등 매우 까다롭다.In the case of metal-controled air ducts, in addition to the above-mentioned drawbacks, construction in a desired shape, for example, right angles, acute angles, and obtuse angles, cannot be performed and curved treatments are required. Very tricky etc.

반면에 합성수지관제 공기덕트의 경우에는 범용성은 아니어서 사용예가 그다지 흔치는 않지만 반드시 관계수와 씰재를 이용해 접속시공해야 하는 불편과 증량감도 있고 설비비용이 높아 비경제적이라는 단점이 있다.On the other hand, synthetic resin air ducts are not universal, so they are rarely used. However, there is a disadvantage in that they are inconvenient and need to be connected by using relational water and seal materials, and they are uneconomical due to high equipment costs.

더욱이, 그 어느 소재나 다같이 규격(길이)에 제한받기 때문에 이음새를 갖지 않는 긴 터널형태의 공기덕트는 얻을 수가 없다.Moreover, since all materials are limited to the standard (length), long tunnel-type air ducts having no seams cannot be obtained.

나아가, 이들 종래의 공기덕트에 있어서의 단열시공은 공기덕트 설치후에 이 공기덕트의 외면에 유리섬유나 발포수지를 덧씌우거나, 이렇게 덧씌운 단열재의 외면을 알루미늄 포일로 감싸주는 것이었다. 특히 유리섬유의 경우에는 섬유설 또는 그 파편이 날려 작업자의 건강을 해칠 우려가 크고 취급에 세심한 주의를 기울여야 한다.Furthermore, the insulation work in these conventional air ducts is to cover the outer surface of the air duct with glass fiber or foamed resin or to wrap the outer surface of the heat insulator covered with aluminum foil after the air duct is installed. Especially in the case of glass fiber, the fiber snow or its fragments may be blown off and the worker's health may be seriously handled with great care.

또, 공기덕트의 설치와 보온처리를 별도로 시행하므로서 공사기간의 장기화, 인건비 지출의 과다 등의 면에서 경제적으로도 불리하다.In addition, separate installation of air ducts and thermal insulation treatment are disadvantageous economically in terms of lengthening the construction period and excessive labor cost.

본고안의 이같은 종래 공기덕트의 단점을 말끔히 해소할 수 있는 신규의 공기덕트를 제공하는데 그 목적을 둔 것으로서, 가요성이 풍부해 기하학적인 곡선형태의 시공이 가능하고, 가볍고 내식성 또한 우수하며, 합성수지 호스처럼 길게 제조할 수 있어 이음새 없는 공기덕트의 시공이 실현가능하고 또한 경제적으로도 매우 유리한 것이 특징이다.Its purpose is to provide a new air duct that can alleviate the shortcomings of the conventional air duct in this paper. It is flexible and can be constructed in geometrically curved form, and it is light and corrosion resistant. As long as it can be manufactured, the construction of a seamless air duct is feasible and economically very advantageous.

더욱이, 단열제가 공기덕트 내면에 실시되어 있어서 공기덕트의 시공기간이 짧고 위생상 안전한다.Furthermore, since the insulation is applied to the inner surface of the air duct, the construction period of the air duct is short and it is hygienic and safe.

이하, 실시예를 토대로 작성한 첨부도면과 관련지어 더욱 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings made on the basis of examples.

본고안은 전체적으로 보면 나선관형태를 이루고 있다.In general, this paper is in the form of a spiral tube.

여기서, 공기덕트의 기재는 테이프(1)이다. 이 테이트(1)의 합성수지 필름을 일정한 폭으로 재단한 내면 소재의 외면에 알루미늄막을 입힌 이른바 수지-포일 테이프이다. 이 테이프(1)는 인열강도와 인장강도 및 내열성이 모두 우수한 것일수록 좋다.Here, the base of the air duct is the tape 1. It is a so-called resin-foil tape which coated an aluminum film on the outer surface of the inner surface material which cut | disconnected the synthetic resin film of this tate 1 to constant width. The tape 1 is better to be excellent in both tear strength, tensile strength and heat resistance.

나아가, 화재등에 대비하여 방염처리한 것이면 더욱 좋다.Furthermore, it is better if it is flameproofed in preparation for a fire.

상기 테이프(1)의 이음새 부분은 상기 테이프(1)와 같은 피치로 두른 강선(3)의 외면에 얹힌 상태에서모양의 삽입홈(21)을 가진 결속밴드(2)에 의해 모두 긴밀하게 씌워져 있다. 이 결속밴드(2)는 유연성과 내열성 장점등을 두루 갖춘 합성수지제이며 길다란 선밴드이다. 이와같이 테이프(1)와 한 피치를 돌아서 인접하게 되는 테이프와의 접속부(1a)(1b)는 강선(3)을 완전히 휘감은 상태에서 결속밴드(2)의 삽입홈 (21) 내면과 강선(3)의 외면사이에서 결속밴드(2)자체의 탄성에 힘입어 긴밀하게 끼어지진다.The seam portion of the tape 1 is placed on the outer surface of the steel wire 3 wrapped at the same pitch as the tape 1 All are closely covered by the binding band 2 having the insertion groove 21 in the shape. This binding band (2) is made of a synthetic resin with long flexibility and heat resistance advantages, and is a long line band. In this way, the connection portions 1a and 1b of the tape 1 which are adjacent to the tape 1 by turning the tape 1, the inner surface and the steel wire 3 of the insertion groove 21 of the binding band 2 in the state where the steel wire 3 is completely wrapped. The band 2 is tightly sandwiched by the elasticity of the binding band 2 itself.

그리고, 삽입홈(21)의 수직부(22)에는 강선(3)을 휘돌아 내려온 접속부(1a) (1b)의 끝부분과 상대측 테이프(1) 부분이 맞닿는 면이 교대로 사이에 끼인채 강력한 탄성에 의해 몰려있다. 이로써 나선상으로 두른 테이프(1)의 모든 겹친 부분은 접착제의 도움없이 견고한 결속상태를 간직하게 되는 것이다.In addition, a strong elasticity is inserted into the vertical portion 22 of the insertion groove 21 by alternately sandwiching the end portions of the connecting portions 1a and 1b, which have come down the steel wires 3, and the mating surface of the mating tape 1. Flocked by. As a result, all the overlapping portions of the spirally taped 1 retain a solid binding state without the aid of an adhesive.

상기 결속밴드(2)를 알루미늄이나 기타 금속재로 하면 소성 변형이 일어나기도 하고, 또 경우에 따라서는 부식되기 쉽기 때문에 극력 피하는게 좋다. 그리고, 상기 강선(3)은 열수축율이 낮고 인장강도가 큰 합성수지제 선등으로 대체하는 것도 고려할 수가 있다.When the binding band 2 is made of aluminum or other metal material, plastic deformation may occur, and in some cases, it is easy to corrode, and thus it is best to avoid it. In addition, the steel wire 3 may be considered to be replaced by a synthetic resin wire having a low thermal contraction rate and a high tensile strength.

그리고, 이렇게 이뤄지는 공기덕트의 내면에는 단열재(4)가 접합되어 있다. 이 단열재(4)는 유리섬유 등과 같이 가요성과 내열성이 우수한 것으로 한다. 이 단열재(4)에서 가요성을 요구하는 것을 축방향으로 접거나 펼칠수 있게하여 시공서, 운방 및 보관성을 갖도록 하기 위해서이다.And the heat insulating material 4 is joined to the inner surface of the air duct made in this way. This heat insulating material 4 shall be excellent in flexibility and heat resistance like glass fiber. This is to allow the insulation material 4 to be folded or unfolded in the axial direction so as to have flexibility in construction work, transportation, and storage.

상기와 같이 결속밴드(2)와 강선(3)에 의하여 테이프(1)의 겹친 부분이 견고하게 결속되는 것은 물론, 이부분에 있어서의 구성 방향으로의 내압축강도 및 복원력도 동시에 강화되어 공기덕트로서의 형상유지에 매우이롭다. 또한, 테이프(1) 자체가 유연성이 뛰어나고 게다가 결속밴드(2)와 강선(3)이 공기덕트의 축방향에 대한 유연성도 함께 갖기 때문에 직각, 예각, 둔각을 비롯하여 그 밖의 기하학적인 임의의 곡선형태로의 시공도 가능할 뿐아니라, 축방향으로 접고 펴기가 쉬워 시공성도 좋고 적은 부피로 접어서 보관, 운반할 수 있는 가 하면, 종래에 비해 훨씬 저렴한 가격으로 제작 보급할 수 있는 것은 물론, 내면쪽기이 단열효과가 우수하고 가요성이 풍부한 비교적 얇은 두께의 단열재가 미리 접합되어 있어서, 적어도 단열재 시공에 뒤따르는 공기와 인건비의 지출이 필요치 않아 경제적으로 시공할수가 있다.As described above, not only the overlapped portion of the tape 1 is firmly bound by the binding band 2 and the steel wire 3, but also the compressive strength and the restoring force in the configuration direction in this portion are also strengthened at the same time. It is very beneficial to maintain shape as. In addition, since the tape 1 itself is highly flexible and the binding band 2 and the steel wire 3 also have flexibility in the axial direction of the air duct, right-angled, acute-angled, obtuse angles and other geometric arbitrary curved shapes In addition to the construction of the furnace, it is easy to fold and unfold in the axial direction, and the workability is good, and it can be folded and stored and transported in a small volume. Since a relatively thin thickness heat insulator is pre-bonded with excellent effect and flexibility, it is possible to economically construct at least the expense of air and labor costs following the construction of the heat insulator.
