방화문 기밀 구조{Sealing structure of fireproof door}Sealing structure of fireproof door

본 고안은 방화문과 문틀의 틈새를 통하여 전달되는 소음 및 난방열의 손실을 방지하는 한편 실내외 온도 차이로 인한 결로 현상이 발생하지 않도록 하는 방화문 기밀 구조에 관한 것이다.The present invention relates to an airtight door airtight structure that prevents noise and heating from being transmitted through the gap between the fire door and the door frame, and prevents condensation due to a difference between indoor and outdoor temperatures.

통상 방화문과 문틀의 틈새는 문틀에 끼워진 하나의 패킹으로 기밀이 유지되게 하고 있으나, 하나의 패킹으로 기밀을 유지하기에는 냉난방 부하의 손실과 소음차단을 시킬 수 없을 뿐 아니라, 내외부 온도차로 인하여 발생하는 결로 현상을 방지할 수 없는 것이었다.Normally, the gap between the fire door and the door frame keeps airtight with one packing inserted in the door frame.However, in order to keep airtight with one packing, it is not possible to prevent the loss of air-conditioning load and noise blocking, and it is caused by the internal and external temperature difference. The phenomenon could not be prevented.

이러한 문제를 해결하기 위하여 국내 실용신안등록 20-305980호에는 기 사용되는 하나의 패킹 이외에 방화문의 외측으로 모헤어를 끼움으로써 기밀유지와 냉난방 부하의 손실을 방지하고 있으나, 소음차단이 쉽지 않고 특히 내외부 온도차로 인하여 발생하는 결로현상을 방지할 수 없는 것이었다.In order to solve this problem, Korean Utility Model Registration No. 20-305980 prevents airtightness and loss of heating and cooling load by inserting mohair to the outside of fire door in addition to one packing that is already used. Due to the condensation phenomenon could not be prevented.

또한 국내 실용신안등록 20-390271호에는 두 개의 패킹을 사용하여 밀폐와 차단성을 높임으로써 냉난방 부하의 손실 방지와 소음을 차단하는 효과가 있으나, 내외부 온도차로 인하여 발생하는 결로현상을 방지할 수 없는 것이었다.In addition, the Korean Utility Model Registration No. 20-390271 has the effect of preventing the loss of cooling and heating loads and blocking the noise by improving the sealing and blocking property by using two packings, but it cannot prevent the dew condensation caused by the internal and external temperature difference. Was.

그리고 국내 실용신안등록 20-246626에도 두 개의 패킹을 사용하여 밀폐와 차단성을 높임으로써 냉난방 부하의 손실 방지와 소음을 차단하는 효과를 제공하는 한편 기존의 방화문 후방에 패널을 부착함으로써 단열의 효과를 높이고 있으나, 소음 차단과 냉난방 부하의 손실은 어느 정도 차단하는 하는 한편 단열성을 높여 결로 현상을 방지하는 효과가 있으나, 기밀성과 단열 효과가 뛰어나다고 볼 수 없는 것이었다.In addition, the Korean Utility Model Registration 20-246626 also uses two packings to increase the sealing and blocking properties, providing the effect of preventing the loss of air-conditioning load and blocking the noise. Although it is increasing, noise blocking and loss of heating and cooling load are blocked to some extent, and the effect of preventing condensation by increasing insulation is not considered to be excellent in airtightness and insulation effect.
