Description
본 고안은 유체나 기체등을 통과시키기 위한 덕트의 구조에 관한 것으로서, 특히 용접 및 접착가공의 공정이 필요없는 3층 구조 덕트에 관한 것이다.The present invention relates to a structure of a duct for passing a fluid or gas, and more particularly, to a three-layer structure duct that does not require welding and adhesive processing.
종래에 사용하는 덕트는 일반적으로 함석판이나 플라스틱 판넬등을 2차 가공하여 만들었다. 즉 함석의 경우는 도 1에 도시되어 있듯이 함석판(10)을 절단하여 구부리거나 휘어서 성형부(12)를 형성하여 사각 모양으로 만든다음 양단부의 겹치는 부분을 용접하여 제작한다. 그러므로 각 덕트에는 용접부(11)가 형성되어 있으며, 이러한 2차 가공과 용접을 하는 공정이 별도로 이루어져야 하므로 공사기간이 길어지는 문제점이 있고, 또 함석판의 경우 단열등의 문제로 석면을 사용하여 보온을 유지하고 있어서 별도의 보온재를 부착하여야 하는 문제가 발생한다.Conventionally used ducts are generally made by secondary processing of tin plates or plastic panels. That is, in the case of tin, as shown in FIG. 1, the tin plate 10 is cut and bent or bent to form the molding part 12 to make a square shape, and then weld the overlapping portions of both ends. Therefore, the welding portion 11 is formed in each duct, and the secondary processing and the welding process must be performed separately, so there is a problem in that the construction period is long, and in the case of the tin plate, asbestos is used to insulate as a problem such as insulation. There is a problem that needs to attach a separate insulation.
본 고안은 전술한 문제점을 해결하기 위하여 안출한 것으로서, 별도의 보온재의 부착이 필요 없으며, 용접 또는 접착가공이 필요없어 완제품 상태로 부속연결등의 간단한 공사로 절단 및 접합등의 공사기간을 단축할 수 있는 3층 구조 덕트를 제공하고자 하는 목적을 가지고 있다.The present invention has been devised to solve the above-mentioned problems, and does not require the attachment of a separate thermal insulation material, and does not require welding or adhesive processing, so that the construction period of cutting and joining can be shortened by simple construction such as connecting parts in the finished product state. The purpose is to provide a three-layer structure duct that can be.
본 고안은 전술한 목적을 달성하기 위하여 덕트(duct)에 있어서, 상기 덕트를 3층구조로 형성하여 가운데 층은 플라스틱 발포층으로 하며 상기 발포층의 상하면에 경질 플라스틱을 각각 위치되도록 하여 압출 성형 시켜 접합부 없이 제조되며 강도, 보온성이 뛰어난 것을 특징으로 하는 3층 구조 덕트를 제공한다.The present invention in the duct (duct) in order to achieve the above object, by forming the duct in a three-layer structure, the middle layer is a plastic foam layer and the extrusion molding by placing the hard plastic on the upper and lower surfaces of the foam layer, respectively The present invention provides a three-layer structure duct manufactured without a joint and characterized by excellent strength and thermal insulation.

＜ 도면의 주요 부분에 대한 부호의 간단한 설명 ><Brief description of symbols for main parts of the drawings>
1, 3 : 경질 플라스틱 2 : 발포층1, 3: hard plastic 2: foam layer
4 : 표면4: surface
이하 첨부된 도면을 참조하여 본 고안의 구성을 상세히 설명하면 다음과 같다.Referring to the configuration of the present invention in detail with reference to the accompanying drawings as follows.
도 2에 도시되어 있듯이 3층구조로 형성하여 가운데 층은 플라스틱 발포층(2)으로 하며 상기 발포층(2)의 상하면에 경질 플라스틱(1)(3)을 각각 위치되도록 하여 압출 성형 시킨다.As shown in FIG. 2, the three-layer structure is formed into a plastic foam layer 2 and extruded to have the hard plastics 1 and 3 positioned on the upper and lower surfaces of the foam layer 2, respectively.
이렇게 형성된 덕트의 표면(4)에는 UV를 차단하는 막을 도포시켜 자외선에 의한 물성변화를 막아주고 산화방지를 통한 제품의 내구성을 높여준다.The surface 4 of the duct thus formed is coated with a film that blocks UV, thereby preventing changes in physical properties caused by ultraviolet rays and increasing durability of the product through oxidation prevention.
그리고 경질 원재료에 안료를 첨가하면 다양한 색상을 만들 수 있어서 인테리어 측면에서도 우수한 제품이 될 수 있다.In addition, the addition of pigments to the hard raw material can make a variety of colors can be an excellent product in terms of interior.
내충격 복합 경질 플라스틱을 사용함으로써 강도 및 내충격성에 뛰어나며 플라스틱 발포를 이용하여 제품중량을 최소화시킬 수 있다.Impact-resistant composite hard plastics are superior in strength and impact resistance, and plastic foam can be used to minimize product weight.
이상과 같이 본 고안은 기존의 덕트와는 달리 경질프라스틱, 발포층, 경질프라스틱의 3개층이 4각기둥형태로 압출성형되어 나오므로 4각형태로 다시 용접 및 접착가공이 필요없어 공기를 단축할 수 있으며, 경질 플라스틱으로 인하여 강도 및 내충격성에 뛰어나며, 발포층이 포함되어 제품중량을 가볍게하고 뛰어난 보온효과가 있다.As described above, unlike the conventional duct, the three layers of hard plastic, foam layer, and hard plastic are extruded in the shape of a quadrangular column, so the welding and adhesive processing are not required again in the quadrangular form, so that the air can be shortened. It is excellent in strength and impact resistance due to hard plastics, and includes a foam layer to lighten the product weight and has an excellent thermal insulation effect.
또한 경질 플라스틱의 원재료에 안료를 첨가하면 다양한 색상의 덕트를 제작할 수 있으므로 외관이 미려하다.In addition, when the pigment is added to the raw material of the hard plastic, it is possible to manufacture a duct of various colors, so the appearance is beautiful.
