강재골조의 내화구조체{Fireproof construction of Steel Frames}Fireproof construction of steel frames

본 발명은 강재골조의 내화구조체에 관한 것으로, 건축물의 하중을 지지하는 강재골조의 둘레를 따라 타공이 형성되어 있는 지지부재를 통해 내화보드와 단열재를 시공하여 내화성능이 우수하고, 시공이 매우 간편하게 이루어지는 강재골조의 내화구조체에 관한 것이다.The present invention relates to a fire resistant structure of a steel frame, and to construct a fireproof board and insulation through the support member is formed along the periphery of the steel frame to support the load of the building, the fire resistance performance is excellent, the construction is very easy It relates to the fire resistant structure of the steel frame made.

근래에는 건물의 고층화 대형화로 인한 공기단축과 고강도의 건축물을 시공하기 위하여 S.R.C(Steel Reinforced Concrete)공법을 이용한다.In recent years, S.R.C (Steel Reinforced Concrete) method is used to construct high-strength buildings and shortening of air due to high and large buildings.

또한 이러한 대형, 고층화된 건축물은 화재발생에 대한 위험이 매우 심각하게 대두되어 유사시 건물의 안전도와 인명보호가 매우 중요한 요소로 부각되어 정부에서는 내화기능을 가진 불연재 및 내화피복재의 사용을 법적으로 규정하고 있다.In addition, such large and high-rise buildings have a serious risk of fire, and in case of emergency, safety and life protection of buildings are very important factors, and the government stipulates the use of non-combustible materials and fireproof materials with fireproof functions. have.

상기 내화기능이란 건축물이 장시간의 화재시에도 재료의 형태나 강도 등이 크게 변하지 않고 견디어 내어 인명 및 재산을 보호하고, 화재 후 간단한 수선으로 건축물의 재사용이 가능하게 하는 기능이다.The fire-resistant function is a function that allows the building to endure without changing the form or strength of the material even during a long time fire, to protect people and property, and to reuse the building by a simple repair after the fire.

종래에는 상기와 같은 내화기능을 나타내기 위하여 강재골조인 기둥이나, 보를 형성하는 H빔에 내화피복재 슬러리나, 반죽상태로 만든 다음 습식 또는 건식으로 뿜칠하여 내화피복재가 피복되도록 구성하였다.Conventionally, in order to exhibit the fire resistance function as described above, a fireproof coating slurry or dough is formed on a H-beam forming a steel frame or a beam, and then made wet or dry, and then sprayed wet or dry to cover the fireproof coating material.
