Description
본 고안은 차음과 방화성능이 요구되는 칸막이벽에 관한 것이다. 더욱 구체적으로, 본 고안은 2겹의 방화석고보드와 CRC보드(cellulose reinforced cement board)를 이용하여 차음성능과 내화성능이 우수하고 습기와 충격에 강한 칸막이벽에 관한 것이다.The present invention relates to a partition wall requiring sound insulation and fire protection performance. More specifically, the present invention relates to a partition wall that is excellent in sound insulation and fire resistance and resistant to moisture and impact by using two-layer fireproof gypsum board and CRC board (cellulose reinforced cement board).
종래에는 차음과 방화성능이 요구되는 내부 칸막이벽으로 보통 벽돌 또는 블록 등을 사용한 습식조적방식을 주로 사용하여 왔으나, 최근에는 외국에서 도입한 경량화와 건식구조를 위한 석고보드 고정칸막이벽 방식을 많이 사용하고 있다.Conventionally, wet partitioning methods using bricks or blocks have been mainly used as internal partition walls that require sound insulation and fireproof performance, but recently, foreigners use plasterboard fixed partition walls for lightweight and dry structures. Doing.
상기 종래의 습식조적방식은 벽돌이나 블록을 쌓아 내벽을 형성하고 상기 내벽의 벽면을 모르터로 미장하여 마감한 것으로써, 단열성능을 위해서는 별도의 단열재를 부착하여야 하며, 습식시공으로 인하여 시공성이 떨어지고 적지 않은 양생시간이 요구된다. 또한 벽돌과 블록 자체의 무게로 인하여 설치가 용이하지 않은 문제점이 있다.The conventional wet forming method is to build an inner wall by stacking bricks or blocks and finish by plastering the wall surface of the inner wall with a mortar, and to insulate a separate insulating material for insulation performance. Curing time is required. In addition, there is a problem that the installation is not easy due to the weight of the brick and the block itself.
상기 종래의 석고보드 고정칸막이벽은 목재나 경량철골을 이용하여 뼈대를 형성하여 그 가운데 단열재를 삽입하고, 두께 9∼12mm의 석고보드를 상기 뼈대의 양측면에 못이나 나사못을 사용하여 박은 후, 상기 석고보드의 이음부는 석고 플라스터를 바르거나 종이테이프를 붙이고, 벽 전체를 수성페인트로 칠하여 이음부를 알아볼 수 없게 한 것이다. 상기 석고보드 고정칸막이벽의 두께 9∼12mm의 석고보드는 1시간 내화구조와 어느 정도의 차음성능으로써는 만족되나, 그 이상의 내화성능과 차음성능은 요구되기 어려우며, 수성페인트와 석고보드의 특성상 습기와 충격에 약한 문제점이 있어 차음과 방화성능이 요구되는 곳에서는 사용하기 어려웠다.The conventional gypsum board fixing partition wall forms a skeleton using wood or lightweight steel frame and inserts a heat insulating material therein, and puts a plasterboard having a thickness of 9 to 12 mm on both sides of the skeleton using nails or screws, and then The joints of the gypsum boards are covered with gypsum plaster or paper tape, and the entire wall is painted with water-based paint to make the joints unrecognizable. The gypsum board with a thickness of 9 to 12mm of the gypsum board fixed partition wall is satisfied with a fireproof structure and a certain sound insulation performance for one hour, but more fire resistance and sound insulation performance are difficult to be required, and due to the nature of water-based paint and gypsum board, It is difficult to use where sound insulation and fire protection are required due to the weakness and impact.
본 고안의 목적은 차음성능 및 내화성능이 우수하고, 충격 및 습기에 강하며, 현장작업을 통해 시공이 간편하고, 경우에 따라 지하층 내부이중벽 및 비내력 외벽으로도 사용이 가능하며, 설치와 철거가 용이한 칸막이벽을 제공하는 것이다.The purpose of the present invention is excellent sound insulation and fireproof performance, strong against shock and moisture, and easy to install through on-site work, and can be used as double wall and non-bearing exterior wall in underground floor, in some cases, installation and dismantling It is to provide easy partition wall.
