Description

팽창성 발포제를 갖는 방화문Fire doors with expandable blowing agents
본 발명은 팽창성 발포제를 갖는 방화문에 관한 것으로, 더욱 상세하게는 화재시 방화문 내에 구비되는 팽창성 발포제가 방화문이 변형되는 방향으로 발포되어 변형되지 않도록 방지되는 팽창성 발포제를 갖는 방화문에 관한 것이다. The present invention relates to a fire door having an intumescent foam, and more particularly to a fire door having an intumescent foam which is prevented from being deformed by being foamed in the direction in which the fire door is deformed in case of fire.
일반적으로 방화문은 주택, 아파트, 공장, 사무실, 조립식 가설건물 등에 화재가 번지는 것을 차단하기 위해 출입구 또는 비상구에 설치되는 구조물로써, 벽을 관통하여 설치되는 사각형상의 문틀과, 이러한 문틀 사이에 회동수단(예컨대, 힌지)에 의해 결합되는 문짝으로 이루어진 구조이다.In general, a fire door is a structure installed at an entrance or an emergency exit to prevent a fire from spreading in a house, apartment, factory, office, prefabricated temporary building, etc., and a rectangular door frame installed through a wall, and a rotation means between the door frames. It is a structure consisting of doors joined by (for example, hinges).
이러한 문틀과 문짝에는 단열성능을 부여하기 위해 그 내부에 단열재를 채우고, 그 외곽은 금속판으로 이루어진 것이 대부분이나, 화재 발생시 밀폐된 실내 온도가 높아지는 경우 1차적으로 열변형된 후 단열재가 연소되어 가스가 방출되면서 열과 압력에 의해 팽창과 동시에 강도가 취약한 부분에서 비틀림이 발생한다.In order to provide insulation performance, such door frames and doors are filled with a heat insulating material inside, and the outermost part is made of a metal plate. However, when a closed room temperature increases in the event of a fire, the heat insulating material is first burned and the gas is burned. As it is released, torsion occurs in areas with weak strength while expanding due to heat and pressure.
특히 힌지가 문틀에 결합된 부분보다 힌지 반대쪽 부분에서 비틀림이 심하게 일어나는데, 이때 문틀과 문짝 사이에 틈새가 벌어지면서 유해가스와 함께 화염이 실외로 번져 인명피해가 커지는 원인이 되고 있다.In particular, the torsion occurs more severely on the opposite side of the hinge than the hinge is connected to the door frame, and the gap between the door frame and the door opens, causing the flame to spread outdoors with harmful gases, causing more casualties.
이와 같은 방화문의 변형을 방지하기 위해 대한민국 등록특허공보 제10-0591734호 '변형력 흡수 방화문'이 알려져 왔다.In order to prevent the deformation of such a fire door has been known Republic of Korea Patent Publication No. 10-0591734 'deformation absorbing fire door'.
방화문에 가해지는 고온의 화염에 의해 발생하는 재질의 물성변화를 흡수하고, 방화문의 내구성을 증대시키는 소재를 방화문내에 구비하여 방화문의 변형력을 흡수한다.Absorb the deformation of the fire door by absorbing the material property change caused by the high temperature flame applied to the fire door and increasing the durability of the fire door.
그러나 변형력 흡수 방화문에 구비되는 고가의 소재로 인해 비용이 상승하여 경제적인 부담이 높아 일반적인 가정에 사용할 수 없는 문제점이 있었다.However, due to the expensive material provided in the deformation absorbing fire door, there is a problem that can not be used in a general household due to high economic burden.
이러한 문제점을 해결하기 위해 간단한 구성과 구조를 갖추어 비용이 절감되며 일반적인 가정에 사용 가능하며 화재시 방화문의 변형을 방지할 수 있는 기술이 요구되고 있다.In order to solve these problems, a simple configuration and structure are required to reduce costs, can be used in a general home, and a technique for preventing deformation of a fire door in a fire is required.

여기서 상기 세라믹패드(500)는 상기 문짝(200)의 후방 내측과 상기 제1 수직보강대(410) 사이에 배치되는 제1 세라믹패드(510)와 상기 제1 세라믹패드(510)와 대응되며 상기 문짝(200)의 전방 내측과 상기 제2 수직보강대(420) 사이에 배치되는 제2 세라믹패드(520)와 상기 제1 세라믹패드의 타측에 구비되며 상기 문짝의 후방 내측과 상기 케이스의 후면 사이에 배치되는 제3 세라믹패드로 구성된다.The ceramic pad 500 corresponds to the first ceramic pad 510 and the first ceramic pad 510 disposed between the rear inner side of the door 200 and the first vertical reinforcing bar 410 and the door A second ceramic pad 520 disposed between the front inner side of the 200 and the second vertical reinforcing bar 420 and the other side of the first ceramic pad, and disposed between the rear inner side of the door and the rear side of the case; Consisting of a third ceramic pad.
일반적으로 일측이 힌지(10) 연결되는 상기 방화문은 화재시 개폐가능한 상기 손잡이(20)가 구비되는 타측부터 휘어지면서 변형이 된다.In general, the fire door is connected to one side hinge 10 is deformed while bending from the other side provided with the handle 20 that can be opened and closed in the event of a fire.
화재로 인한 상기 방화문의 변형을 방지하기 위해 상기 팽창성 발포제(400)가 열에 의해 방화문이 휘어지는 방향으로 발포되도록 갖추어진다.In order to prevent deformation of the fire door due to a fire, the expandable foaming agent 400 is provided to foam in a direction in which the fire door is bent by heat.
이로 인해 본 발명에 따른 팽창성 발포제를 갖는 방화문은 내화성이 우수하며 화재로 인한 변형이 방지되어 화염이나 연기가 바깥으로 나오지 않게 된다.For this reason, the fire door having the expandable blowing agent according to the present invention has excellent fire resistance and prevents deformation due to a fire so that flames or smoke do not come out.
