Description

차열 방화셔터용 하부바{under bar for fireproof shutter insulating heat}Under bar for fireproof shutter insulating heat}

본 발명은 차열 방화셔터용 하부바에 관한 것으로, 상세하게는 화재시 가이드 레일을 따라 자유롭게 승강되도록 설치되는 방화셔터의 셔터슬레이트 하단에 결합되어 바닥면과 밀착되는 하부바를 차열시켜 화재에 따른 고열을 완벽하게 차단할 수 있도록 할 뿐만 아니라 이중 이상으로 차단할 수 있도록 하는 차열 방화셔터용 하부바에 관한 것이다.
The present invention relates to a lower bar for thermal insulation fire shutters, and in detail, is coupled to the bottom of the shutter slate of the fire prevention shutter installed so as to freely move along the guide rail in case of fire, and heats the lower bar in close contact with the bottom surface, thereby perfecting high heat according to the fire. The lower bar for the heat shield fire shutter to be blocked as well as to block more than double.

일반적으로 건축물에는 화재 발생시 발화지점을 신속히 봉쇄함으로써 화재가 주위로 확산하는 것을 방지하는 동시에 인명을 보호할 수 있도록 건축법 및 소방법 소정의 규정에 정한 바에 따라, 방화셔터의 설치를 의무화하고 있다.In general, a building is mandated to install a fire shutter according to the provisions of the Building Code and the Fire Code to prevent the fire from spreading to the surroundings and to protect human life.

이러한 방화셔터는 상하로 연결되는 길쭉한 판상의 슬레이트와, 상기 슬레이트를 상하로 승강 이동시킬 수 있도록 건물의 측벽에 매설하는 가이드레일, 그리고 건물의 천정에 설치되며 슬레이트를 승강시키는 구동장치가 내장되어 있는 셔터박스로 이루어진다.The fire shutter has an elongated plate-like slat connected up and down, a guide rail embedded in the side wall of the building to move the slat up and down, and a driving device installed on the ceiling of the building and lifting the slat. It consists of a shutter box.

이와 같은 방화셔터는 슬레이트에 의하여 봉쇄되는 특정공간 내부로 외부사람이 진입하는 것을 억제하는 기능과 더불어, 화재 발생시 외부공기가 발화지역으로 유입되어 피해지역을 확산시키게 되는 것을 차단하여 조기 진화가 가능토록 함은 물론, 화염 및 유독가스가 외부로 방출되는 것을 방지하는 등 여러 가지의 기능을 만족시킬 수 있어야만 한다.Such a fire shutter prevents the outside from entering a specific space blocked by the slate, and prevents external air from entering the ignition zone and spreads the damage zone in the event of a fire. Of course, it must be able to satisfy various functions such as preventing the emission of flame and toxic gas to the outside.

이러한 종래의 방화셔터는 최근에 화염의 근접 등으로 인한 고열을 차단할 수 있는 차열 방화셔터를 개발하고 있으나 화재의 고열이 하부바를 통해 크게 전도되는 문제점이 있었다.Such a fire prevention shutter has been recently developed a heat shield fire shutter that can block the high heat due to the proximity of the flame, but there was a problem that the high heat of fire is largely conducted through the lower bar.

더욱이 차열 방화셔터를 2중 구조로 형성하는 경우 고열을 적절하게 차단할 수 있는 하부바의 개발이 지속적으로 요구되어 왔다.
Moreover, when forming a heat shield fire shutter in a double structure, the development of a lower bar that can properly block high heat has been continuously required.

따라서 본 발명은 주목적은 차열 방화셔터에 있어서 하부바를 효과적으로 차열하여 화재에 따른 고열을 전도되는 것을 억제할 수 있도록 하는 차열 방화셔터용 하부바를 제공하는 데 있다.Accordingly, an object of the present invention is to provide a heat shield fire shutter lower bar that can effectively prevent the high heat caused by the fire by effectively shielding the lower bar in the heat shield fire shutter.

본 발명의 다른 목적은 2중 구조의 차열 방화셔터에 있어서 하부바를 절단하여 열전도를 차단하므로 화재에 따른 고열을 전도되는 것을 억제할 수 있도록 하는 차열 방화셔터용 하부바를 제공하는 데 있다.
Another object of the present invention is to provide a heat shield arrest shutter lower bar that can suppress the conduction of high heat due to fire because the lower bar cuts heat conduction in the heat shield arrest shutter having a double structure.

상기한 목적을 달성하기 위하여 본 발명의 차열 방화셔터용 하부바는 다수개 순차적으로 결합된 슬레이트의 하단을 삽입하여 결합하되 내부에 차열체를 충진 시킨 메인프레임과; 상기 메인프레임의 외부에 일정간격을 유지하면서 감싸되 내부에 차열체를 삽입하고 차열체와 메인프레임 사이에 공간을 형성하는 중간프레임과; 상기 중간프레임의 외부에 일정간격을 유지하면서 감싸되 내부에 차열체를 삽입하고 차열체와 중간프레임 사이에 공간을 형성하는 외부프레임; 및 상기 메인프레임, 중간프레임, 외부프레임의 소정위치를 절단하여 차열체를 삽입하여 열전도를 차단하는 차단부로 구성함을 그 기술적 구성상의 기본 특징으로 한다.In order to achieve the above object, the lower bar for thermal insulation fire shutter of the present invention includes a main frame in which a heat shield is filled therein by inserting and combining a lower end of a plurality of sequentially coupled slate; An intermediate frame wrapped around the outside of the main frame while inserting a heat shield therein and forming a space between the heat shield and the main frame; An outer frame wrapped around the outside of the intermediate frame while inserting a heat shield therein and forming a space between the heat shield and the intermediate frame; And a cut-off part which cuts a predetermined position of the main frame, an intermediate frame, and an outer frame to insert a heat shield to block heat conduction.

따라서 본 발명의 차열 방화셔터용 하부바는 화재가 근접하여 고열을 발생시키면 슬레이트의 최하단에 결합된 하부바의 내부에 충진 또는 삽입된 차열체가 화재로부터의 고열을 효과적으로 차단하여 화염 및 고열에 따른 화재의 확산을 억제할 뿐만 아니라 메인프레임과 중간프레임 및 외부프레임 사이에 공간을 형성하여 이러한 차열 효과를 더욱 향상시켜 화재의 확산을 효율적으로 억제할 수 있도록 하고 더욱이 이중 구조를 갖는 차열 방화셔터의 슬레이트 하부를 용이하게 결합하하고, 메인프레임, 중간프레임, 외부프레임의 소정위치를 절단하여 그 사이에 차열체를 삽입하여 결합하므로 차열 효율을 극대화시키는 효과가 있다.
Therefore, when the lower bar for heat shield arson shutter of the present invention generates high heat close to the fire, the heat shield filled or inserted inside the lower bar coupled to the lower end of the slate effectively blocks the high heat from the fire, and thus the fire according to the flame and high heat. In addition to suppressing the spread of air, the space between the main frame, the middle frame and the outer frame is further enhanced to further improve the heat shielding effect, thereby effectively suppressing the spread of fire, and furthermore, the bottom structure of the heat shielded fire shutter having a double structure. Easily coupled to, and cut the predetermined position of the main frame, the intermediate frame, the outer frame to insert the heat shield between the coupling there is an effect of maximizing the heat shielding efficiency.
