본 발명은 전파흡수기능이 구비된 도로의 방음벽에 관한 것으로서, 특히 전자파를 흡수하여 전파장애를 없앨 수 있으며, 소음을 흡수할 수 있는 도로의 방음벽에 관한 것이다.The present invention relates to a soundproof wall of a road provided with a radio wave absorption function, and more particularly, to a soundproof wall of a road capable of absorbing electromagnetic waves to eliminate radio interference and absorbing noise.

일반적으로 고속도로나 유료도로의 갓길 또는 주택단지의 인근에 위치한 도로에는 방음벽이 설치되어 있다.In general, sound barriers are installed on the shoulders of highways and toll roads, or on roads near residential complexes.

그러나 종래의 방음벽은 소음을 흡수하는 기능을 가지는 것일 뿐, 전파의 반사체가 되기 때문에 설치장소에 따라서는 전파장애가 발생되는 문제점이 있었다.However, the conventional soundproof walls only have a function of absorbing noise, and thus become a reflector of radio waves, so that there is a problem that radio interference occurs depending on the installation place.

일례로 전파를 이용한 자동영역 수수시스템(ETC)이나 고속도로 교통시스템(ITS)이 채용되는 장소에서는 노상구조물이나 방음벽재로 부터의 전파의 난반사가 발생하고, 노상통신장치나 차내의 통신장치의 오작동을 발생시킬 우려가 있다.For example, in places where the automatic area transfer system (ETC) or the highway traffic system (ITS) using radio waves are adopted, diffuse reflection of radio waves from the roadbed structure or the soundproof wall material occurs, and the malfunction of the roadside communication device or the communication device in the vehicle is prevented. There is a risk of occurrence.

특히 자동영역 수수시스템(ETC)이 설치되는 요금소로는 일정한 장소에 설치 된 안테나로부터 차량에의 전파의 전파경로가 복수가 되고 이중과금이 발생된다는 문제가 있었다.In particular, there is a problem that multiple charge paths are generated and double billing is generated in a toll station in which an automatic area transfer system (ETC) is installed in a certain place.

또한, 전파의 원활한 흡수를 위하여 미국이나 일본등에서는 페라이트 타일(ferrite tile)등을 설치하고 있는 것이 일반적이나, 방음벽에 상기의 페라이트 타일(ferrite tile)등을 부착하게 되면 방음벽으로서의 성능이 저하되는 문제점이 있게 된다.In addition, in order to smoothly absorb radio waves, ferrite tiles and the like are generally installed in the United States and Japan. However, when the ferrite tiles are attached to the soundproof walls, the performance of the soundproof walls is degraded. This will be.

도1과 도2 및 도3에 도시된 바와같이, 본 발명의 일측페라이트커버(10)는 일측에는 지주체(100)의 웨지부(101)에 끼움되어 하부로 슬라이딩되도록 양측의 거치단(11)과 돌출단(12) 사이에 한쌍의 슬라이딩홈(13)이 형성되고, 타측에는 돌출단(14)이 형성되는 한편, 상부와 전면 및 배면이 개방되고 내부가 중공상태로 되어 흡음패널(200)이 상부에서 하부로 삽입되는 구조이다.As shown in Figures 1 and 2 and 3, one side ferrite cover 10 of the present invention is fitted to the wedge portion 101 of the support body 100 on one side so as to slide downwards on both sides 11 ) And a pair of sliding grooves 13 are formed between the protruding end 12 and the protruding end 14 is formed on the other side, while the top, front and back are open and the inside is hollow, and the sound absorbing panel 200 is formed. ) Is inserted from top to bottom.

상술한 흡음패널(200)은 전방에 다수의 유입홀(201a)이 형성되고, 일측면에는 흡음재(202)가 투입되어 내장되도록 측면홀(201b)이 형성되어 있는 흡음재커버(201)로 구성되며, 흡음재커버(201)는 작업이 용이하도록 경량의 에프알피를 재질로 하는 것이 바람직하다.The above-mentioned sound absorbing panel 200 is composed of a sound absorbing material cover 201 is formed with a plurality of inlet holes (201a) in the front, the side hole 201b is formed so that the sound absorbing material 202 is inserted into one side. , The sound absorbing material cover 201 is preferably made of a light weight of RF Al to facilitate the work.

그리고 본 발명의 타측페라이트커버(20)는 일측페라이트커버(10)와 동일한 형상이되, 일측페라이트커버(10)의 돌출단(14)이 삽입되어 장볼트(a) 및 너트(b)로 고정되도록 양측의 삽입대(22) 사이에 삽입부(21)가 일측에 형성된 구조이다.And the other ferrite cover 20 of the present invention has the same shape as the one side ferrite cover 10, the protruding end 14 of the one side ferrite cover 10 is inserted and fixed with a long bolt (a) and nuts (b) The insertion part 21 is formed in one side between the insertion stand 22 of both sides as much as possible.

그리고 본 발명의 끼움대(30)는 지주체(100)의 상단에 끼움되도록 평단면이 'H'형상으로 상부에서 하부로 관통되어 있는 삽입홀(31)이 형성되고 양측면에는 끼움홈(32)이 구비된 구조이다.And the fitting table 30 of the present invention is formed so that the insertion hole 31 is penetrated from the top to the bottom in the 'H' shape so that the flat section is fitted to the upper end of the support body 100 and the fitting groove 32 on both sides This is a structure provided.

상기의 일측페라이트커버(10)와 타측페라이트커버(20) 및 상부페라이트커버(40)의 재질인 페라이트는 아철산염이라고도 하며 여러 종류의 전자장치에 이용되는 자성이 있는 세라믹 같은 물질을 말한다.Ferrite, which is a material of the one side ferrite cover 10, the other side ferrite cover 20, and the upper ferrite cover 40, is also called ferrite and refers to a magnetic ceramic material used in various types of electronic devices.

즉, 페라이트는 단단하고 부서지기 쉬우며 철을 포함하고 있고 보통 회색이나 검은색의 다결정, 즉 수많은 작은 결정으로 이루어져 있다. 화학적 조성을 보면 산화철과 하나 이상의 다른 금속으로 되어 있다. 페라이트는 산화철(Ⅲ)(녹)과 마그네슘,알루미늄,바륨,망간,구리,니켈,코발트,철 등의 여러 가지 다른 금속이 반응하여 형성된다.In other words, ferrite is hard, brittle, contains iron, and usually consists of gray or black polycrystals, that is, many small crystals. The chemical composition consists of iron oxide and one or more other metals. Ferrite is formed by the reaction of iron (III) oxide (rust) with various other metals such as magnesium, aluminum, barium, manganese, copper, nickel, cobalt and iron.

페라이트의 화학식은 보통 M(FexOy)로 표현되는데, M은 앞에서 언급된 원소들 중 그가 결합하는 금속을 나타낸다. 예를 들어 아철산니켈은 NiFe2O4이며, 아철산망간은 MnFe2O4로 둘 다 첨정석 광물이다. The chemical formula of ferrite is usually represented by M (FexOy), where M represents the metal to which it binds. For example nickel ferrite is NiFe2O4 and manganese ferrite is MnFe2O4, both of which are spinel minerals.

희토류 원소인 이트륨을 포함하고 있는 YIG(Yttrium Iron Garnet:Y3Fe5O12)로 알려진 석류석 광물은 마이크로파 회로에 쓰인다. 가장 잘 알려진 페라이트는 성서시대부터 알려진 것으로 화학식이 Fe(Fe2O4)인 자철석(자화석 또는 아철산철(Ⅱ))이다. 페라이트는 준강자성이라고 하는 자성을 띠는데 이는 철,코발트,니켈 같은 물질의 강자성과는 구별된다(→ 준강자성). 페라이트는 이들 구성 원자의 자기모멘트가 서로 다른 두 방향 또는 세 방향으로 배열된다. A garnet mineral known as YIG (Yttrium Iron Garnet: Y3Fe5O12) containing yttrium, a rare earth element, is used in microwave circuits. The most well known ferrites are known from Biblical times and are magnetite (magnetite or iron ferrite (II)) with the formula Fe (Fe2O4). Ferrite has a magnetism called ferromagnetic, which is distinguished from ferromagnetic properties of materials such as iron, cobalt, and nickel (→ semiferromagnetic). Ferrites are arranged in two or three directions with different magnetic moments of these constituent atoms.

자기장은 부분적으로 상쇄되어 페라이트는 전체적으로 강자성 물질보다는 약한 자기장을 갖게 된다. 원자 방향성에 부분적으로 존재하는 이 비대칭성의 원인은 2개 이상의 다른 종류의 자기 이온이 존재하거나 특징적인 결정 구조 때문이다. The magnetic field is partially offset so that the ferrite has a weaker magnetic field than the ferromagnetic material as a whole. This asymmetry, partly due to atomic orientation, is due to the presence or presence of two or more different kinds of magnetic ions or characteristic crystal structures.

준강자성이라는 용어는 프랑스의 물리학자 루이스 닐이 만들었는데 그는 최초로 원자 수준에서 체계적으로 페라이트를 연구한 사람이었다. 준강자성은 몇 가지 종류가 있다. 동일 직선상 준강자성은 자기장이 반대방향으로 일렬로 배열된 것이고, 3각형 준강자성은 자기장이 서로 다른 각도로 놓여진 것이다. 페라이트는 첨정석 구조, 석류석 구조, 회티탄석 구조, 육방 구조 등 다양한 결정 구조를 갖는다(→ 지구 자기장). The term quasi-ferromagnetic was coined by French physicist Louis Neil, who was the first to study ferrite systematically at the atomic level. There are several types of semiferromagnetics. Colinear ferromagnetics are magnetic fields arranged in a line in opposite directions, and triangular semiferromagnetics are magnetic fields placed at different angles. Ferrite has various crystal structures such as spinel structure, garnet structure, gray titanium stone structure, hexagonal structure (→ the earth's magnetic field).

페라이트의 가장 중요한 성질은 자기투과성이 크고 전기저항이 크다는 점이다. 자기장에 대한 투과성이 크기 때문에 페라이트가 안테나 같은 장치에 쓰이며, 정4각형 고리 페라이트로 알려진 형태의 페라이트는 전류에 의해 두 방향 중 한 방향으로 자화될 수 있다. The most important property of ferrite is its high magnetic permeability and high electrical resistance. Ferrites are used in devices such as antennas because of their high permeability to magnetic fields. Ferrites, also known as square-ring ferrites, can be magnetized in one of two directions by electrical current.

이 성질로 인해 페라이트가 디지털 컴퓨터 기억 장치로 유용하게 쓰이는데, 이는 매우 작은 페라이트 고리가 2진수 비트의 정보를 저장할 수 있기 때문이다. 다른 형태의 컴퓨터 기억장치는, 거품기억소자라고 하는 아주 작은 자기영역에서 각각 조종될 수 있는 특정 단결정의 페라이트로 만들 수도 있다(→ 자기거품기억소자). 많은 페라이트는 한 방향으로만 마이크로파 에너지를 흡수하므로 마이크로파의 도파관으로 이용된다.This makes ferrite useful for digital computer storage because very small ferrite rings can store binary bits of information. Other types of computer memory can also be made of specific single crystal ferrites that can be manipulated in a very small magnetic area, called a foam memory device. Many ferrites are used as microwave waveguides because they absorb microwave energy in only one direction.

상기와 같은 페라이트를 이용하여 본 발명의 일측페라이트커버(10) 및 타측페라이트커버(20)와 상부페라이트커버(40)는 페라이트의 표면에 방수 코팅막을 형성하여 사용할 수도 있다.The ferrite cover 10 and the other ferrite cover 20 and the upper ferrite cover 40 of the present invention using the ferrite as described above may be used by forming a waterproof coating film on the surface of the ferrite.
