Description
본 고안은 폐합성수지 및 폐콘크리트를 이용하여 제조되는 인도블럭에 관한것으로서 보다 구체적으로는 폐콘크리트 및 폐합성수지재를 성형하여 충진블록을 형성하고 충진블록의 상면 및 둘레를 신재(新材)의 합성수지를 사출하여 충진블록을 포삽하여 제조되는 폐합성수지 인도블럭의 충진블록과 외장블록의 결합구조에 관한 것이다.The present invention relates to a delivery block manufactured using waste synthetic resin and waste concrete, and more specifically, to form a filling block by molding waste concrete and waste synthetic resin material, and to form a filling block on the top and circumference of the filling block. It relates to a coupling structure of the filling block and the outer block of the waste synthetic resin delivery block produced by inserting the filling block by injection.
주지된 바와 같이 인도블록은 사람의 보행을 위하여 노면에 설치되는 블록으로 종래에는 주로 시멘트와 모래를 이용하여 블록을 성형하여 사용하였으나 근래에는 자원의 재활용을 목적으로 하여 폐합성수지 및 폐콘크리트등의 폐자재를 이용하여 성형하는 인도블럭이 다수 제안되어 사용되고 있다.As is well known, the India block is a block installed on the road for human walking. In the past, the block is mainly formed by using cement and sand, but recently, waste materials such as waste synthetic resin and waste concrete are recycled for the purpose of recycling resources. Many sidewalk blocks molded using materials have been proposed and used.
즉 종래의 폐자재를 사용하여 인도블럭을 제조하는 것은 주로 폐합성수지에 폐콘크리트분쇄물,고로의 슬레그 등을 혼합하여 인도블록의 형태로 성형하여 사용되어 왔으나 이는 제조되는 블록에 색상을 부여할 수 없는 결점이 있었다.In other words, the manufacture of sidewalk blocks using conventional waste materials has been mainly used in the form of sidewalk blocks by mixing waste concrete grinds, blast furnace slag, etc. There was an uncountable flaw.
즉 수거되어 재활용되는 폐합성수지는 용도에 따라 물건의 재조시에 다양한 색상으로 제조됨으로서 이를 수거하여 용융시켜 블록을 형성하면 기존의 폐합성수지의 색상이 혼합되어 원하는 색상의 인도블럭을 얻을 수 없음으로 실용화되지 못하였고 이를 개선하여 근래에는 상기의 폐합성수지블록에 다양한 색상의 표현이 가능한 신재(新材)의 합성수지로 폐합성수지성형물을 포삽하여 형성하거나 신재(新材)의 합성수지판재를 폐합성수지블록의 표면에 부착한 인도블럭이 제안되어 사용되고 있다.In other words, the waste synthetic resins collected and recycled are manufactured in various colors when remanufacturing according to the purpose. When the waste synthetic resins are collected and melted to form blocks, the colors of the existing waste synthetic resins are mixed to obtain a delivery block of a desired color. In recent years, the synthetic resin plate is formed by inserting waste synthetic resin molding into new synthetic resin that can express various colors in the waste synthetic resin block, or by forming a new synthetic resin board material on the surface of the waste synthetic resin block. A delivery block attached to the wall is proposed and used.
그러나 상기와 같이 폐합성수지블록의 표면에 신재(新材)를 인서트사출 하여 제조하는 것은 다수의 종류의 폐합성수지를 혼합하여 블록을 성형함으로서 폐합성수지의 종류와 포삽하는 신재(新材)의 합성수지의 재질이 틀리게되면 서로 융착이 되지않고 단순히 포삽한 형태로 제조된다.However, as described above, the production of new material by inserting new material on the surface of the waste synthetic resin block is performed by mixing a plurality of types of waste synthetic resin to form a block to form the type of waste synthetic resin and the new synthetic resin of the new synthetic material. If the materials are wrong, they are not fused to each other and are simply manufactured.
즉 물성이 다른 합성수지류는 서로 접착이 되지 않는 경우가 많으므로 폐합성수지로 성형되는 충진블록과 충진블록의 표면에 형성되는 외장블록이 긴밀하게 결합하기 위해서는 폐합성수지를 종류별로 분류하여 충진블록을 성형함으로서 충진블록을 인서트사출시에 신제또한 충진블록과 동일한 재질의 합성수지를 사용하여 충진블록과 외장블록을 결합할수는 있으나 폐합성수지를 수거하여 종류별로 분류하는 것은 합성수지의 종류가 다양하고 육안으로는 구분이 어렵고 분리비용에 의한 원가상승 요인으로 작용할뿐만 아니라.제조공정상 인서트되는 충진블록과 동일한제질의 외장블록재료를 수시로 교체해 주어야 하는 등의 불편으로 인하여 통상 폐합성수지를 분류하지 않고 용융성형하여 신재(新材)의 외장블록으로 감싼형태의 인도블럭을 제조하거나 충진블록의 표면에 신재(新材)의 합성수지판재를 접착재로 부착하여 제조되는 인도블럭이 사용되고 있으나 이는 기온및 기후의 변화 즉 하절기와 동절기에 재질이 다른 충진블록과 인장블록의 열팽창계수의 차이에 의한 접착부의 이격과 접착부에 우수와 먼지등의 이물질의 유입등 외부환경에 의해 신재(新材)의 외장블록이 폐합성수지블록으로부터 이격되어 벗겨지고 접착부가 벌어지게 됨으로 내구성이 약하여 실용성이 떨어지는 결점이 있었다.In other words, synthetic resins with different physical properties are often not adhered to each other. Therefore, in order to closely combine the filling block formed from waste synthetic resin and the outer block formed on the surface of the filling block, the filling block is classified by type of waste synthetic resin. By inserting the filling block into the insert block, it is possible to combine the filling block and the outer block by using synthetic resin of the same material as the filling block, but the sorting of the waste synthetic resin and sorting them by type is diverse and visually classified. In addition to this difficult and costly increase due to the separation cost, due to the inconvenience of having to replace the exterior block material of the same material as the insert block inserted in the manufacturing process, it is usually melt-molded without sorting the waste synthetic resin. 인도) The delivery block of the form surrounded by the external block In India blocks, which are manufactured by attaching new synthetic resin plates to the surface of the filling block as adhesives, are used, but this is due to changes in temperature and climate, that is, the coefficient of thermal expansion of filling blocks and tension blocks of different materials in summer and winter. The exterior block of new materials is peeled away from the waste synthetic resin block due to the external environment such as the separation of the adhesive part due to the difference and the inflow of foreign substances such as dust and the like. There was a flaw.
본 고안은 상기와 같은 종래의 결점을 개선코자 안출한 것으로서 폐합성수지로 성형되는 충진블록의 외주 및 필요부분에 인서트사출되는 신재(新材)의 합성수지가 충진 및 관통하여 걸림턱을 형성함으로서 폐합성수지재로 성형되는 충진블록과 신재(新材)의 외장블록이 구조적으로 결합되게 함으로서 외장블록과 충진블록을 긴밀하게 결합시켜 충진블록과 신재(新材)의 외장블록이 분리되지 않도록 폐합성수지 인도블럭의 충진블록과 외장블록의 결합구조를 제안함에 그 목적이 있다.The present invention devised to improve the above-mentioned drawbacks, and the synthetic resin of the new material, which is injected into the outer periphery and the required portion of the filling block formed from the waste synthetic resin, is filled and penetrated to form a locking step. Filled blocks formed from ash and outer blocks of new materials are structurally combined so that the outer blocks and the filled blocks are tightly coupled so that the synthetic resins are not separated from the filled blocks and the new blocks. The purpose is to propose a combined structure of the filling block and the outer block of the.
