본 고안은 건물의 온 냉풍기용 닥트(Duct)와 닥트를 연결함에 있어서 불연성의 유리섬유직포에 P.V.C방염 코팅을 하여 필요에 따라 자유자재로 굽혀서 연결할 수 있도록 한 닥트연결관에 관한 것이다.The present invention relates to a duct connector that can be bent freely as needed by applying a P.V.C flame-retardant coating on the non-combustible glass fiber fabric in connecting the duct and the duct for the hot and cold air of the building.
종래의 한석철판이나 PVC 호오스를 사용하였으나 이는, 막대한 경제적 부담을 주었고, 무게가 무거울 뿐만아니라, 필요시마다 닥트관을 굽혀서 연결하여야하는데에도 굽힐수가 없어서 굽혀야할 양단을 절취하거나, 별개의 부품을 사용하여 연결하므로 시공상의 난점과 시간의 소비가 많은 폐단이 있었다.Conventional Hanseok iron plate or PVC hose was used, but it was immensely economical, it was not only heavy but also needed to bend and connect the duct tube whenever necessary, so that it could not be bent and cut off both ends or used separate parts. There was a lot of trouble in construction and time-consuming connection because of the connection.
또한, 천막기지의 안과밖에 고무로 코팅한 다음 철사로 권회하여 사용되거나, 또는 석면을 부분적으로 사용하는 것이 있으나, 천막기지에 고무코팅하여 사용되는 경우에는 화재의 위험이 있었고 석면을 사용하는 경우에는 수입품이므로 원료의 확보가 어려우면서도, 고가이므로 비경제적인 폐단이 있었다.In addition, the coating of rubber inside and outside of the tent base may be used by winding with wire or partially using asbestos. However, when rubber coating is used on the tent base, there is a risk of fire and when asbestos is used. Although it was difficult to secure raw materials because of imported goods, it was expensive and there was an uneconomic closure.
본 고안은 이러한 문제점들을 해결하고져 P.V.C 방염코팅을 한 불연성의 직포를 철관에 권회하고 강선으로 다시한번 감아준 다음 상기와 같은 직포를 중첩하여 권회하고 유리섬유실로 감은 다음 철관을 탈리하면 필요시마다 굽혀서 사용될 수 있는 자바라식 닥트연결관이 형성되는 것으로, 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention solves these problems and wound the nonflammable woven fabric with PVC flame-proof coating on the steel pipe, and then wound it again with a steel wire, then wrapped the above woven fabric, wound it with a fiberglass thread, and bent it as needed when detaching the steel pipe. A bellows-like duct connector is formed, which will be described in detail with reference to the drawings as follows.
닥트연결관(1)을 형성함에 있어서 제2a도에 도시한바와 같이 불연성의 유리섬유직포(4)의 외면에 P.V.C방염코팅(5)[P.V.C, T.C.P(Tri Cresv1 Phosphate; (CH3C6H4O)3PO), 염화파라핀, 하이카가소제, 시리케이트, 안정제(T.L.S)(Trebasec Lead Sulfate; 3PbO PbSO4H2O), 안치몬, 삼염화에치렌, TiO2(Titanium Diozide), 염료등을 혼합하여 토루엔으로 희석하여 코팅한 후 170~180℃ 온도에서 1분가량 열처리함]이된 직포(2)를 공지의 철관에 권회하고, 강선(6)을 권회된 직포(2)위로 나선모양으로 권설한 다음, 전기와 같은 방법으로 내면에 P.V.C 방염코팅 (5')이된 불연성의 직포(3)를 제2c도에서와 같이 다시 한번 권회한후, 불연성인 유리섬유실(7)로 유리섬유직포(4')의 위로 다시 권설한다. 이 때, 직포(4)에 권설된 강선(6)과 강선(6) 사이사이로 권설하고, 이와같이 권설이된 다음 철판을 닥트연결관(1)내에서 탈리시키면 강선(6)과 유리섬유실(7)의 탄성에 의하여 자바라식 호스모양으로 형성된다.In forming the duct connecting tube 1, as shown in FIG. 2A, the PVC flame retardant coating (5) [PVC, TCP (Tri Cresv1 Phosphate; (CH 3 C 6 H) on the outer surface of the non-flammable glass fiber woven fabric 4 is shown. the 3PbO PbSO 4 H 2 O), placed Mon, chiren, TiO 2 (Titanium Diozide) in phosphorus trichloride, dyes and the like; 4 O) 3 PO), chlorinated paraffins, hayika plasticizers, coloring Kate, stabilizers (TLS) (Trebasec Lead Sulfate After mixing, diluting with toluene, coating and heat-treating at 170 to 180 ° C. for 1 minute], the woven fabric (2) is wound in a known steel pipe, and the steel wire (6) is spirally wound onto the wound woven fabric (2). And then wound the non-flammable woven fabric (3) coated with PVC flame-resistant coating (5 ') on the inner surface again in the same manner as before, as shown in FIG. 2C, and then glassed with the non-flammable glass fiber yarn (7). It is rolled up again on the textile fabric 4 '. At this time, it is recommended to be sandwiched between the steel wire (6) and the steel wire (6) recommended in the woven fabric (4), and the steel plate is detached in the duct connecting pipe (1) after the winding is made in this way, the steel wire (6) and glass fiber thread ( It is formed in a bellows type hose by the elasticity of 7).
이와같이 형성된 본 고안의 작용효과를 설명하면 다음과 같다. 불연성의 유리섬유 직포(4)(4')의 외면과 내면에 P.V.C 방염코팅(5)(5')이 된 직포(2)와 직포(3)의 사이에 탄성체의 강선(6)으로 권설되어있고 다시금 직포(4')와 그위로 불연성 유리섬유실(7)로 권설되어 있다.Referring to the effect of the present invention formed as described above are as follows. An elastic steel wire 6 is recommended between the woven fabric 2 and the woven fabric 3, which are PVC flame retardant coatings 5, 5 'on the outer and inner surfaces of the non-combustible glass fiber woven fabric 4, 4'. Again, it is recommended to have a woven fabric 4 'and a non-combustible glass fiber chamber 7 thereon.
이와같이 형성된 닥트연결관(1)은 공지의 철관을 탈리하면 탄성체의 강선(6)과 유리섬유실(7)의 인장력에 의하여 자바라식의 형상이 되어 자유자재로 굽혀진다.When the duct connecting tube 1 formed as described above is detached from the known iron tube, it is bent freely by the bellows shape by the tensile force of the steel wire 6 and the glass fiber chamber 7 of the elastic body.
그러므로 시공시에 건물의 돌출부 및 요홈부를 피하는 등의 불편이없이 쉽게 시공할수 있을 뿐만 아니라 시공자의 원하는 모양의 형태로 자유자재로 굽혀서 작업할 수 있어서 시간의 단축은 물론이고, 막대한 경제적잇점이 있으며, 유리섬유 직포가 불연성이기 때문에 외부 또는 내부에 열이 가하여져도 연소가 되지않고, 방염코팅으로 인하여 열전도가 차단되어 온냉풍기의 온도를 일정하게 유지하여주는 잇점이 있다.Therefore, the construction can be easily performed without inconvenience, such as avoiding the protrusions and grooves of the building, and can be bent freely in the desired shape of the contractor, thereby reducing the time and enormous economic advantages. Since the glass fiber woven fabric is nonflammable, it does not burn even when heat is applied to the outside or inside, and thermal conductivity is blocked due to the flame retardant coating, thereby keeping the temperature of the hot and cold fan constant.
그러므로서 종래의 닥트연결관을 연결시에 절단 또는 별개의 부품을 이용하는 등의 번거로움이나, 불편등을 해결한 유용한 고안이다.Therefore, it is a useful design that solves the inconvenience and inconvenience such as cutting or using separate parts when connecting a conventional duct connector.
