Description
본 발명은 단열성 및 휨강도가 향상된 경량콘크리트 패널 및 그 제조방법에 관한 것으로, 보다 상세하게는 내부 벽체용으로 사용되는 경량콘크리트 패널의 단열층에 새로운 조성물을 포함하여 단열성을 향상시키고, 마감층으로 초고성능콘크리트(UHPC, ultra-high performance concrete)보드를 사용하여 휨강도를 향상시킨, 단열성 및 휨강도가 향상된 경량콘크리트 패널 및 그 제조방법에 관한 것이다.The present invention relates to a lightweight concrete panel with improved thermal insulation and bending strength, and a method of manufacturing the same. The present invention relates to a lightweight concrete panel having improved insulation and bending strength by using an ultra-high performance concrete (UHPC) board, and a method of manufacturing the same.
일반적으로, 건축물의 내외장재는 건축물의 외적 미려함과 단열을 위하여 다양한 건축재가 사용되고 있다. 외벽 마감재로는 천연화강석을 주로 사용하여 왔다. 그러나, 천연화강석을 사용하는 경우 자연에서 채석하여야 하므로 자연훼손이 불가피하여 환경파괴의 원인을 제공하였다. 또한, 천연화강석을 건축물의 외장마감재로 사용함으로써 건축물에 많은 하중을 주고, 철근과 시멘트를 과도하게 사용하여 골조 구성 원가가 높아지고 별도로 내·외벽의 단열을 하여야 하는 등의 문제가 있어 왔다.In general, a variety of building materials are used for interior and exterior materials of buildings for external beauty and insulation of buildings. As exterior wall finishing materials, natural granite has been mainly used. However, when natural granite is used, natural damage is inevitable because it must be quarried in nature, thereby providing a cause of environmental destruction. In addition, by using natural granite as an exterior finishing material of the building, there has been a problem of giving a lot of load to the building, excessively using reinforcing bars and cement, and increasing the cost of constructing the frame and separately insulating the inner and outer walls.
위와 같은 문제를 해결하기 위하여 조강 시멘트와 스티로폴 비드(styropor bead)를 혼합한 혼합경량콘크리트를 두 장의 CRC보드(Cellulose Reinforced Cement Board) 사이에 충진하여 일체로 성형한 건축물의 내외장용 패널이 개발되었다. 이러한 건축물의 내외장용 패널은 대한민국등록실용신안공보 제20-0158855호(1999.10.15.) "건축물의 내외장용 판넬"에 자세하게 기재되어 있다.In order to solve the above problems, an interior and exterior panel of a building in which a mixed light concrete mixed with crude steel cement and styropor bead is filled between two CRC boards (Cellulose Reinforced Cement Board) is formed. The interior and exterior panels of such buildings are described in detail in Korean Registered Utility Model Publication No. 20-0158855 (October 15, 1999) "Interior and exterior panels of buildings."
그러나, 상기 건축물의 내외장용 판넬은 단순히 두 장의 CRC보드의 사이에 조강시멘트와 크기가 극히 작은 스치로플의 입자들이 골고루 혼합되어 제조되는 경량기포 콘크리트를 채운 구조로서, 두 장의 CRC보드 사이에 스티로폴 비드와 조강 시멘트를 혼합한 혼합경량콘크리트만을 채워 일체로 형성함으로써, 강도와 단열효과가 우수하지 못하였다. 강도를 증가시키기 위하여 혼합경량콘크리트의 두께를 두껍게 하면 중량이 증가되어 건축물에 많은 하중을 주는 문제가 있고, 건축물의 내·외장의 골조 구성원가가 상승되는 요인이 된다.However, the interior and exterior panels of the building is simply a structure filled with lightweight foamed concrete prepared by mixing the cement of the cement steel and the particles of very small squirrel evenly between the two CRC boards, Styropole beads between the two CRC boards And integrally formed by mixing only the mixed light weight concrete mixed with the crude steel cement, the strength and heat insulation effect was not excellent. Increasing the thickness of the mixed lightweight concrete in order to increase the strength, the weight is increased, there is a problem that gives a lot of load on the building, the frame member of the interior and exterior of the building is a factor that increases.
상기 문제를 해소하기 위해, 대한민국공개특허공보 제10-2011-0017793호(2011.02.22.)에는 건축물 내외장용 경량패널 구조체가 개시되어 있다.In order to solve the problem, Korean Patent Laid-Open No. 10-2011-0017793 (2011.02.22.) Discloses a lightweight panel structure for building interior and exterior.
상기 건축물 내외장용 경량패널 구조체는 거푸집형태의 구조를 갖는 CRC틀의 내부에 충전되어 양생되는 혼합경량콘크리트를 폐유리, 폐타이어 및 EPS 비드를 혼합 조성함으로써 경량콘크리트의 강도를 증대시킴과 동시에 단열효과를 증대시킨 장점이 있지만, 강도 및 단열효과가 충분치 못한 단점이 있다.The light weight panel structure for interior and exterior of the building is a mixture of waste glass, waste tire and EPS bead mixed with the mixed lightweight concrete, which is filled and cured in a CRC frame having a form structure, to increase the strength of the light concrete and at the same time, the insulation effect. There is an advantage to increase, but there is a disadvantage that the strength and insulation effect is not enough.
본 발명의 목적은 내부 벽체용으로 사용되는 경량콘크리트 패널의 단열층에 새로운 조성물을 포함하여 단열성을 향상시키고, 마감층으로 초고성능콘크리트(UHPC, ultra-high performance concrete)보드를 사용하여 휨강도를 향상시킨, 단열성 및 휨강도가 향상된 경량콘크리트 패널 및 그 제조방법을 제공하는 것이다.An object of the present invention is to include a new composition in the insulation layer of lightweight concrete panels used for the interior wall to improve the thermal insulation, and to improve the bending strength by using ultra-high performance concrete (UHPC) board as a finishing layer To provide a lightweight concrete panel with improved insulation and flexural strength and a method of manufacturing the same.
