Description

석탄재를 이용한 합성목재 및 그 제조방법{Artificial wood for soundproof wall using coal ash}Synthetic wood using coal ash and its manufacturing method {Artificial wood for soundproof wall using coal ash}

본 발명은 석탄재를 이용한 합성목재에 관한 것으로서, 산업 폐기물인 석탄재를 합성목재 제조에 이용함으로써, 자원재활용적 가치가 뛰어나며, 물에 강하고, 저 신축, 고강도의 합성목재를 제조할 수 있어, 방음벽으로 사용시 외부환경에 의한 뒤틀림 변형 및 노후화 현상이 개선되어 반영구적으로 사용할 수 있는 석탄재를 이용한 합성목재 및 그 제조방법에 관한 것이다.
The present invention relates to a synthetic timber using coal ash, by using coal ash, which is an industrial waste, for the production of synthetic timber, it has excellent resource recycling value, is resistant to water, and can produce synthetic timber of low stretch and high strength. The present invention relates to a synthetic wood using a coal material that can be used semi-permanently due to improved warping deformation and aging due to an external environment during use, and a method of manufacturing the same.

일반적으로, 소리를 차단하는 방음벽은 주로 차량의 소음이 자주 발생하는 도로변이나 철로의 주변에 다양한 형태로 방음벽을 이루어 설치된다.In general, sound barriers that block sound are installed by forming various sound barriers around roadsides or railway lines where noise of vehicles is frequently generated.

방음벽이란, 소음의 전달과정에서 소음을 차단 및 흡수시켜 주변지역의 전반적인 소음분포를 일정기준 이하로 낮추어 주는 소음저감대책용 구조물을 말한다.Soundproof wall refers to a structure for noise reduction measures that blocks and absorbs noise in the transmission of noise and lowers the overall noise distribution of the surrounding area to below a certain standard.

현대의 급속한 산업발전에 따라 교통수단이 다양화되고 있으며, 교통량이 기하급수적으로 증가하는 추세에 있다. 이에 따라, 도로주변, 철로주변, 공항주변에 주거하는 주민들은 교통수단에서 발생하는 소음으로 인해 큰 고통을 받고 있는 것이 현실이며, 이와 같은 각종 소음을 막기 위한 방법으로 방음벽이 주로 사용되고 있는 것이다.With the rapid industrial development of modern times, transportation has been diversified, and traffic volume is increasing exponentially. Accordingly, residents living near roads, railways, and airports are suffering from noise generated by transportation, and sound barriers are mainly used to prevent such noises.

이러한 방음벽의 종류에는 흡음형(음파의 대부분을 흡수함), 반와형(방음판에 의해 음파의 대부분을 반사함), 간섭형(입사되는 음파와 반사되는 음파가 섞여 감쇠됨), 공명형(방음판에 구멍이 뚫려 있고 내부에 공동이 있어 음파가 공명에 의해 감쇠됨) 등이 있다.These types of sound barrier include sound absorption type (which absorbs most of the sound waves), half wave shape (reflects most of the sound waves by the soundproof plate), interference type (attenuated mixture of incident sound waves and reflected sound waves), and resonance type (for the soundproof plate). Holes are punctured and cavity inside, so the sound waves are attenuated by resonance).

이러한 방음벽은 소음이 인접한 건물이나 주택으로 전달되지 않도록 하기 위해서 도로의 가장자리를 따라 일정 높이로 벽면처럼 설치되도록 하고 있다.These sound barriers are intended to be installed like walls at a certain height along the edge of the roadway to prevent noise from being transmitted to adjacent buildings or houses.

또한, 소음이 고층에 전달되는 것을 방지하기 위해, 방음벽의 상단부가 소음발생구역으로 굽어져 설치되기도 한다.In addition, in order to prevent noise from being transmitted to higher floors, an upper end portion of the soundproof wall may be bent to a noise generating area.

즉, 도로에 설치되는 일반적인 방음벽 구조는 기초구조물의 일측에 콘크리트로 이루어진 기초옹벽이 기초구조물을 따라 구축되고, 상기 기초옹벽의 상부에 일정간격을 두고 수직방향으로 지주가 설치되며, 상기 지지와 지주 사이에 투명 아크릴 및 차음(遮音, insulation of sound)재 및 흡음(吸音, acoustic absorption)재가 들어간 방음판 또는 방음패널 등으로 설치 고정되는 구조이다.That is, in the general soundproof wall structure installed on the road, a foundation retaining wall made of concrete is formed along the foundation structure on one side of the foundation structure, and a support is installed in the vertical direction at a predetermined interval on the upper portion of the foundation retaining wall. It is a structure that is installed and fixed with a soundproof panel or a soundproof panel containing transparent acrylic, insulation of sound, and sound absorption material.

근래에 들어 다양한 형태의 방음벽이 제공되고는 있으며, 상기의 구조로 이루어진 방음벽의 경우 음을 반사시키는 차음효과와 흡음효과를 극대화시키는 다양한 형태의 방음벽 구조가 제공되고는 있지만, 대부분이 금속재로된 하우징 내부에 소정의 방음차단구조를 이루고 있는 형태들이다.Recently, various types of soundproof walls have been provided. In the case of the soundproof walls having the above-described structure, various types of soundproof wall structures for maximizing sound insulation and sound absorption effects are provided, but most of them are made of metal housings. It is a form that forms a predetermined sound insulation structure inside.

특히, 금속재 방음벽의 경우에는 눈이나 빗물에 취약하여 쉽게 부식되는 단점이 있기 때문에, 부식된 방음벽을 그대로 방치하게 될 경우, 도로의 미관을 저해시키게 되는 문제점이 있다. 또한, 재시공에 따른 경제적인 부담감을 가중시키게 되는 문제점이 있었다.In particular, in the case of the metal soundproof wall is vulnerable to snow or rain water, there is a disadvantage that easily corroded, when the corrosion soundproof wall is left as it is, there is a problem that inhibits the aesthetics of the road. In addition, there was a problem that increases the economic burden of the reconstruction.

또한, 방음벽은 단순한 벽체형으로 이루어지기 때문에 미관을 돋보이기에는 미흡한 점이 있다.In addition, since the soundproof wall is made of a simple wall, there is insufficient point to stand out the beauty.

그리고 금속패널 조립은 리벳이나 볼트 등을 이용함으로써 조립에 시간이 많이 소요되고 외관상 볼트 머리 등이 노출되는 등의 단점이 있다.In addition, assembling the metal panel takes a long time to assemble by using rivets or bolts, and the like, such that the bolt head is exposed in appearance.

또한 방음벽에 사용되는 자재는 일반적으로 금속재가 사용되는데, 금속재의 경우 그 단가가 비교적 고가이며, 사용되는 금속재의 단가의 변화에 의하여 그 시공비용이 증가하는 문제점이 있다.In addition, the material used for the soundproof wall is generally used a metal material, in the case of the metal material is a relatively expensive unit, there is a problem that the construction cost is increased by the change in the unit price of the metal material used.

그래서, 최근에는 다양한 방음벽이 설치되고는 있으나, 그 구조가 매우 복잡하여 작업시간이 많이 소요되었다.Therefore, in recent years, various soundproof walls have been installed, but the structure is very complicated, it takes a lot of work time.

또한, 구조의 복잡화로 부품수의 증가가 불가피하여 제작단가가 매우 높아지는 문제점이 있었다.In addition, the increase in the number of parts is inevitable due to the complexity of the structure there is a problem that the manufacturing cost is very high.

따라서 방음구조에 따른 방음효과가 탁월하고, 구조가 간단하여 설치 및 보수가 용이하며, 보기 좋은 방음벽을 필요로 하여 환경이나 도시 미감을 고려한 다양한 형태의 목재 형태의 합성목재를 이용한 방음벽이 설치되고 있다.Therefore, the soundproofing effect of the soundproof structure is excellent, the structure is simple and easy to install and repair, and the soundproof wall using various types of synthetic wood in the form of wood considering the environment or the aesthetics of the city is required due to the need for a good soundproof wall. .

상기 합성목재는 목재부스러기(대팻밥 또는 톱밥)와 발포제(發泡劑)를 혼합한 플라스틱을 성형할 때 발포시켜서 천연목재와 비슷한 외관이나 성질을 갖게 한 재료로 사출 또는 압출성형으로 만든다. 플라스틱 원료로서는 폴리스타이렌 ABS수지 등이 쓰이고, 사출(射出) 또는 압출성형으로 만든다. 사출 성형품은 성형 시에 조각이나 나뭇결무늬가 넣어지므로 인쇄나 도장(塗裝) 등의 2차 가공을 하지 않고서도 나무의 질감(質感)을 나타낼 수 있다.The synthetic wood is made by injection molding or extrusion molding of a material having a similar appearance or properties to natural wood by foaming when molding a plastic mixture of wood chips (sawdust or sawdust) and blowing agent (제). As a plastic raw material, polystyrene ABS resin or the like is used, and it is made by injection molding or extrusion molding. Since the injection molded article is engraved or grained at the time of molding, the texture of the wood can be exhibited without performing secondary processing such as printing or painting.

또한 합성목재는 내구성, 내수성이 우수하며 목재와 달리 썩거나 쉽게 뒤틀리지 않으면서도 누구나 시공이 간편하고 유지보수가 거의 들지 않고 반영구적으로 사용 후 재설치도 가능하여 최근 들어 많이 사용되고 있다.In addition, synthetic wood has excellent durability and water resistance. Unlike wood, anyone can easily install and install after semi-permanent use without any decay or easy twisting.

그러나 합성목재로 설치되는 방음벽은 자체 내구성, 내수성은 우수하나 지주와 연결부재들 간에 연결구조가 금속재로 이루어지는 금속의 방음벽 구조에 비해 유지 강도가 감소할 수밖에 없어 잦은 움직임이나 외부 충격으로 연결부위가 쉽게 파손되었다.However, the soundproof wall installed with synthetic wood has excellent durability and water resistance, but the connection strength between the strut and the connecting members is inevitably reduced compared to the soundproof wall structure of the metal, which is made of metal. It is broken.

또한 합성목재 방음패널이 지주와 밀접하게 맞닿아서 설치되는 경우 합성목재의 특성상 온도에 의해 수축과 팽창이 일어날 경우 쉽게 뒤틀리거나 변형되는 사례가 종종 발생 되는 등 여러 문제점이 발생하였다.In addition, when the synthetic wood soundproof panel is installed in close contact with the prop, various problems have occurred, such as the case of easily twisted or deformed when shrinkage and expansion occur due to the characteristics of the synthetic wood.

이에 따라서 온도변화에 따른 수축과 팽창에 대비하고 외부 조건에 대한 보강은 물론, 연결부위 간의 결합력을 증대시킨 합성목재의 개발이 요구되고 있다.
Accordingly, there is a demand for the development of synthetic wood, which is prepared for shrinkage and expansion due to temperature change, reinforcement of external conditions, as well as increase the bonding force between the connection sites.
