When the hemming operation is performed while the first packing 46 is inserted into the first packing groove 40, the fifth side wall 38 is lowered, and at the same time, the key surface 42 and the door 2 packing 48 is folded inward in a state in which the door end surface 34 is bent upward while being inserted into the second packing groove 36 and at the same time the first packing groove 40 is opened So that the door first packing 46 is held in the engaged state and fixed.

따라서, 상기 방화문(2)을 구성하는 전면판(28)과 돌출면판(30)의 조립은 완료되게 되고, 이후로 상기 방화문(2)을 경첩(4)으로 도어프레임(6)에 개,폐 가능하게 결합하면 설치작업은 완료된다. Therefore, the assembling of the front plate 28 and the protruding face plate 30 constituting the fire door 2 is completed and then the fire door 2 is opened to the door frame 6 with the hinge 4, If possible, the installation is complete.

이때, 상기 돌출면판(30)에는 메인패킹(26)이 접하면서 밀폐력을 제공하게 되고, 동시에 상기 도어제1패킹(46)은 프레임단턱면(18)에 접하면서 밀폐력을 제공하게 된다. At this time, the main packing 26 comes into contact with the protruding face plate 30 to provide a sealing force, and at the same time, the door first packing 46 contacts the frame end face 18 to provide a sealing force.

상기와 같이 도어프레임(6)에 설치된 방화문(2)을 닫힘상태로 한 상태에서 화재가 발생하면, 상기 방화문(2)의 돌출면판(30)에 화염으로 인한 열과 매연이 도달하면서 1차적으로 차단되고, 동시에 상기 도어프레임(6)에 설치된 메인패킹(26)이 2차적으로 차단하게 되며, 이후로 상기 도어단턱면(34)에 설치된 도어제1패킹(46)이 3차적으로 차단하게 된다. When a fire occurs in a state in which the fire door 2 provided in the door frame 6 is closed as described above, heat and soot generated by the flame reach the protruding face plate 30 of the fire door 2, At the same time, the main packing 26 provided on the door frame 6 is cut off secondarily, and then the first door packing 46 installed on the door end surface 34 is thirdarily blocked.

상기와는 달리 실외로부터 소음이 방화문(2)측으로 도달하면, 상기 소음은 방화문(2)의 전면판(28)에 부딪치면서 일부가 반사되고, 일부 소음은 도어프레임(6)과 방화문(2)의 틈 사이를 통과하면서 도어제1패킹(46)과 메인패킹(26) 등에 의해 순차적으로 차단 되는데, 따라서 실내는 조용한 상태를 유지할 수 있게 된다. The noise is struck by the front plate 28 of the fire door 2 to partially reflect the noise and the noise is transmitted to the door frame 6 and the fire door 2, The first packing 46, the main packing 26, and the like, so that the room can be maintained in a quiet state.

또한, 상기 메인패킹(26)과 도어제1패킹(46)을 포함한 방화문(2)은 열손실을 차단하게 됨으로, 실내와 실외의 온도차로 인해 발생할 수 있는 결로현상은 방지되며, 동시에 금속재질로 된 도어프레임(6)과 방화문(2)에는 결로현상에 의한 부식은 발생하지 않게 된다. Also, since the fire door 2 including the main packing 26 and the door first packing 46 blocks heat loss, it is possible to prevent condensation that may occur due to a temperature difference between the room and the outside, Corrosion caused by the condensation phenomenon does not occur in the door frame 6 and the fire door 2.

그리고, 상기 도어프레임(6)에 설치된 메인패킹(26)과 방화문(2)에 설치된 도어제1패킹(46)은 층간 소음을 완화시키게 되고, 또한 화재시 고열의 공기 흐름을 차단하게 됨으로 2차적인 화재를 예방할 수 있게 된다. The main packing 26 provided in the door frame 6 and the door first packing 46 installed in the fire door 2 alleviate the interlayer noise and cut off the high- It is possible to prevent fire.
