Therefore, in the related art, in order to build a house or an apartment, concrete, in which bricks, blocks, or cement and sand and gravel are poured, is used to form inner and outer walls of a building. Therefore, the building materials as described above are inconvenient to handle handling because of their heavy weight, especially when concrete is laid, the construction cost is high due to the mixed concrete or person placing one by one, and the construction is difficult in a narrow place. There was this. Not only that, but the weight also had the problem of safety accidents. In addition, the building materials as described above had a problem that the construction cost is high because the material cost is high.

본 발명은 첨부된 도면에 도시된 실시예를 참고로 설명되었으나, 이는 예시적인 것이며, 당해 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 수 있을 것이다.Although the present invention has been described with reference to the embodiments shown in the accompanying drawings, it is intended to be illustrative, and those skilled in the art will understand that various modifications and equivalent embodiments are possible from this.

따라서 본 발명의 진정한 보호범위는 특허청구범위에 의해서만 정해져야 할 것이다.Therefore, the true scope of protection of the present invention should be defined only by the claims.

상기와 같이 본 발명에 따른 산업폐기물을 이용한 경량 콘크리트 판넬에 의하면 그 용도가 첫째, 다양한 기능을 가진 제품으로써, 그 활용범위가 방대하고 또한, 반영구적으로 불변적인 제품이며 둘째, 건축자재로써 기존(FRP,GRC,FRC)등 특수 건축자재와 비교할 시 월등한 경제성, 기능성, 생산성, 다양성을 겸비하고 있는 제품이고 셋째, 기능성을 가지고 있어, 벽면 등의 면 시공이 편리하고 또한 그 작업공법 또는 공정이 간단하여 인건비를 절감할 수 있으며, 넷째, 디자인 측면에서도 보고 느낄 수 있을 정도로 입체감 및 미려함을 갖추고 있는 제품이고, 다섯째, 타 콘크리트제품과는 달리 일반 톱으로도 쉽게 절단할 수 있으며, 특히 나무보다 더욱 쉽게 절단할 수 있고, 타제품과는 달리 전문적인 기능이 없어도 누구나 손쉽게 시공할 수 있다. 상기와 같은 본 발명에 따른 산업폐기물을 이용한 경량 콘크리트 판넬을 종합하여 보면, 무기질 소재로 불에 타지 않으며 화재시에도 유독가스가 발생하지않아 고층건물이나 대단위 아파트 등 안정성이 강조되는 건축물의 내, 외장재로 아주 적합하며, 또한 제품 내부에 포함되어있는 70%의 미세한 독립기포가 열의 전도를 강력하게 차단하므로 일반 콘크리트보다 10배이상의 단열효과가 있어 보다 쾌적한 생활환경을 창출할 수 있으며, 또한 목재와 거의 같은 중량으로 일반 콘크리트 무게의 4분의 1 정도로 가벼워 건물 전체의 경량화와 함께 시공효율, 인력절감 등 경제적이익이 보장되는 초경량의 미래형 건축자재이며, 또한, 가벼우면서도 차음성과 흡음성이 뛰어나 소음이 심한 도심지의 오피스빌딩이나 주거용 건물등의 내외벽제로 좋습니다.According to the light weight concrete panel using the industrial waste according to the present invention as described above, its use is first, as a product having a variety of functions, the scope of use is vast, semi-permanently immutable product and second, existing as a building material (FRP Compared with special building materials such as GRC, FRC, etc., it combines superior economics, functionality, productivity, and diversity. Third, it is functional, making it easy to construct walls, and its work method or process is simple. 4) It is a product that has a three-dimensional effect and beauty enough to see and feel in terms of design. Fifth, unlike other concrete products, it can be easily cut with a general saw, and especially easier than wood. It can be cut, and unlike other products, it can be easily installed by anyone without any professional function. Looking at the light weight concrete panel using industrial waste according to the present invention as described above, the interior material and exterior materials of buildings that emphasize stability, such as high-rise buildings or large apartments do not burn as a inorganic material and does not generate toxic gas in the event of fire. It is very suitable for the product, and 70% of the fine independent bubbles contained inside the product strongly block the conduction of heat, so it has more than 10 times insulation effect than ordinary concrete and can create a more comfortable living environment. It is light weight about one-fourth of the weight of general concrete with the same weight, which is an ultra-light-weight future building material that guarantees economic benefits such as light weight of the whole building, construction efficiency, and manpower reduction. In addition, it is light and has excellent sound insulation and sound absorption. It is good for interior and exterior walls such as office buildings and residential buildings in downtown.

또한, 형틀에 따라 제작이 되므로 사인펜으로 글씨를 쓸 수 있을 정도로 표면이 평활합니다. 이 평활성은 건물의 내구성에 큰 영향을 끼치는 방수재나 외벽마감재의 부착성을 높이는 이외도 건물 내부를 간단히 시공했을 경우에 분가루의 떨어짐이 적어 내장 마감재의 선택과 도색작업 등에 따른 비용을 훨씬 절감할 수 있다. 또한 가벼우면서도 목재와 같이 쉽게 절단 가공되므로 시공이 간편하고 제품의 규격화와 표준화와 건식공법에 의한 시공으로 공사기간의 단축은 물론 공사비용도 대폭 절감 할 수 있는 효과가 있다.In addition, the surface is smooth enough to be written with a signature pen because it is manufactured according to the mold. This smoothness increases the adhesion of waterproofing materials and exterior wall finishing materials that greatly affect the durability of the building. In addition, it is possible to reduce the amount of powder when the interior of the building is simple, which can greatly reduce the cost of selecting interior finishing materials and painting work. have. In addition, it is light and easy to be cut and processed like wood, so the construction is simple, and it is possible to shorten the construction period and greatly reduce the construction cost by the standardization, standardization and construction of the product.
