Title: 적층(積層) 몰탈판과 이를 이용한 꽃담 도판(圖板)의 제조방법
Inventor: LEE MAN HUI
IPC: B44C3/02
Filed: 2010-07-01
Abstract: 본 발명은 꽃담에 사용되는 꽃담도판의 제조 방법에 대한 것이다. 종래의 꽃담도판은 전문 도공에 의하여 황토를 반죽하고 문양을 빚으며 이를 건조한 후 도자기와 같은 방법으로 소성하여 도판의 문양을 제작하고 이를 일정한 틀에 배열하여 석회 반죽으로 채워 고정한 다음 바탕 면과 바닥면을 만들어 꽃담도판을 완성한다.    
이와 같은 방법은 전문 도공이 꼭 필요하고 제작 비용이 현저히 높아 한국의 전통적 조형 예술인 꽃담을 대중화하는 데 어려움이 많은 것이다. 
따라서 본 발명은 복잡한 제작과정을 단순화하고 현대의 발전 된 재료 기술과 기계 기술을 응용하여 어떤 문양이라도 표현할 수 있는 꽃담도판을 제조하여 대중화하고 일반화하려는데 목적이 있는 것이다. 
 본 발명의 목적을 해결하기 위하여는 도자기와 같은 소성 방법을 배제함은 물론 도공의 전문적인 기술이 아닌 현대적 기법, 즉 상온 성형과 양생이 가능한 다양한 몰탈을 이용하여 꽃담도판으로 사용될 적층의 몰탈판을 제작하고, 이 몰탈판 위에 컴퓨터 프로그래밍으로 디자인된 문양을 조각함으로써 간단히 꽃담 도판을 얻을 수 있는 점에 착안한 것이 본 발명의 목적을 달성하는 수단이 되는 것이다. 
본 발명의 개략적 내용은 꽃담도판을 제조함에 있어, 꽃담 도판으로 사용할  적층의 몰탈판을 제작하는 장치를 제공하며, 본 장치를 이용하여 적층의 몰탈판을 제조하는 방법을 제공한다. 또한 제작된 적층의 몰탈판은 다양한 소프트웨어를 이용한 프로그래밍 된 문양을  CNC 조각기, CNC 밀링, 샌드블러스터 등의 조각 기계를 이용하여 기계적으로 조각하여 꽃담도판을 완성하는 방법을 제공하는 것이다. 
 좀 더 상세히 설명하면 꽃담도판을 제작하기 위한 적층의 몰탈판은 주로 3단 정도면 꽃담도판을 표현하는데 적당한데, 최하층은 30~50mm의 두께로 강도 유지를 위한 시멘트 몰탈을 사용하는 것이 바람직하고, 중간층은 5~10mm의 두께로 주로 백색 바탕 면이 되므로 석회, 석고, 백색 시멘트 몰탈, 등을 사용한다. 최상층은 3~10mm의 두께로  황토색의 문양을 이루는 조각 면이 되는데 여기에는 황토몰탈을 사용하는 것이 바람직하다.  
적층의 몰탈판을 제작함에 있어 유의할 것은 기계적 조각이 편리하도록 몰탈 층의 두께를 균일하게 유지해야하며 특히 최상층의 황토 몰탈층은 더욱 그러한데,  이를 해결하기 위하여 본 발명에서는 균일한 두께를 유지할 수 있는 몰탈판 제조장치가 제공된다. 
또한 몰탈판은 각 층간의 재료분리현상과 기공이 생기는 것을  최대한을 방지하여야 하는데, 이는 몰탈판을 제조하는 과정에서 하단 층의 양생이 이루어지기 전에 상단 층의 몰탈 반죽을 겹쳐서 작업함으로써 재료분리현상을 방지할 수 있으며 몰탈판의 제조과정에서 진동 작업대을 이용함으로써 기공의 발생을 줄일 수 있는 것이다. 
양생이 완료된 적층의 몰탈판은 컴퓨터 프로그램으로 프로그래밍 된 꽃담 문양을 조각하는 단계로 진행된다. 프로그래밍 된 문양 디자인은 조각기계의 제어장치와 호환성을 가져야하며 CNC 조각기, CNC 밀링, 샌드블라스터(sand blaster)의 마스킹 필름 제작에 호환되는 소프트웨어인 오토캐드, 일러스트, 코렐드로우 외 여러가지 Cam 프로그램들을 사용한다. 
조각이 완료된 몰탈판은 바로 꽃담도판으로 사용할 수 있으나 특별히 방수,   채색 등이 필요한 경우는 후 가공 처리를 함으로써 더욱 쓰임새 있는 꽃담도판으로 활용할 수 있게 된다.  
본 발명으로 꽃담도판을 사용하여 꽃담을 건축함에 있어 다음과 같은 효과가 있을 것으로 기대한다. 
1. 생산비용과 시간이 현저하게 절감됨으로써 저렴한 가격으로 꽃담을 대중화 하는데 기여할 수 있다. 
2. 본 꽃담의 일반화는 궁궐이나 특별한 장소를 찾지아니하고는 접할 수 없는 한국의 전통 문화와 조형미를 널리 알리는데 기여할 수 있다. 
3. 현대적인 기법으로 생산되므로 어떠한 문양이라도 꽃담에 응용할 수 있으므로 전통 건축 문화의 계승 발전에 기여할 수 있는 효과를 제공할 수 있다.
