Description

매립형 도어 힌지를 가지는 안전 방화문 문틀 구조{Security doors with flush door frame structure, door hinge}{Security doors with flush door frame structure, door hinge}

본 발명은 매립형 도어 힌지를 가지는 안전 방화문 문틀 구조에 관한 것으로, 더욱 상세하게는 방화문과 측면 문틀 사이를 밀폐시켜 단열, 방음, 결로 현상을 배제시키게 하는 것으로 특히, 사용자의 손가락이 방화문 개폐 시 방화문과 측면 문틀 사이에 끼어 안전사고를 유발하는 위험성을 배제시키는 것이다.The present invention relates to a door frame structure for a safety door having a flush-type door hinge, and more particularly, to a structure for sealing a door between a fire door and a side door frame to eliminate heat insulation, soundproofing and condensation, And the risk of causing safety accidents by interposing between side door frames is excluded.

일반적으로, 방화문은 화재발생시 연기와 열기의 침입 또는 확산을 방지하는 역할을 수행한다. 특히 방화문은 아파트와 같은 공동주택의 현관이나 빌딩 사무실의 출입구 등에 설치되고 있다.Generally, a fire door serves to prevent the intrusion or diffusion of smoke and heat when a fire occurs. Particularly, the fire door is installed in the entrance of the apartment house or the entrance of the building office.

한편, 방화문의 문틀은 화재에 강한 금속재질로 제작되며, 방화문의 어느 한쪽에 전달된 열기가 다른 쪽으로 전달되는 것을 최대한 차단할 수 있도록 내부에 방염부재가 채워질 수 있다.On the other hand, the door frame of the fire door is made of a metal material resistant to fire, and a fire-resistant member can be filled in the fire door so as to block the heat transferred to one side of the fire door from being transmitted to the other.

더구나, 방화문과 문틀 사이에 형성된 공간부를 고무패킹 등으로 밀폐시켜 단열, 결로현상 배제, 방음을 수행하는 기술들이 국내 등록특허 제10-1101935호 및 일본공개 특허 제2001-10766호 등에 게재되어 있다. 이러한 기술들은 측면 문틀에 형성된 요입부에 바같측으로 날개편이 형성된 고무 밀폐 패킹을 삽입하여 고정시키는 구성으로 이루어져 있다.In addition, techniques for sealing the space formed between the fire door and the door frame with a rubber packing or the like to perform heat insulation, removal of condensation phenomenon, and soundproofing are disclosed in Korean Patent No. 10-1101935 and Japanese Patent Laid-Open No. 2001-10766. These techniques are configured to insert and fix rubber sealing packings formed with vane pieces in a recessed portion formed in a side door frame.

이와 같은 구성을 가지는 방화문은 닫거나 여는 경우 고무 밀폐 패킹의 날개편이 방화문의 일측단부와 문틀 사이에 형성된 공간부를 밀폐시키는 것이나, 상기 날개편이 얇은 편으로 되어 있어 유동성을 가지므로 공기나 열을 차단하는 효과는 있을지라도 방화문을 조작하는 사용자가 상기 방화문의 일측단부와 문틀 사이에 형성된 공간부에 손가락(또는 손)을 실수로 넣는 경우 손가락의 미는 힘에 의해 날개편이 내측으로 밀려지게 되어 방화문의 개폐 시 방화문 일단부에 손가락이 끼어져 손상을 입게 되는 안전사고 발생이 문제점으로 지적된다.When the door having such a construction is closed or opened, the wing pieces of the rubber sealing packing seal the space formed between one end of the door and the door frame. However, since the wing is made thin and has fluidity, When a user manipulating the fire door mistakenly inserts a finger (or a hand) into a space formed between one end of the fire door and the door frame, the wing member is pushed to the inside by the pushing force of the finger, It is pointed out that a safety accident occurs in which a finger is caught and damaged at one end.

또한, 상기 종래의 고무 밀폐 패킹은 단순히 상기 공간부를 얇은 형태의 날개편을 밀폐 시키는 것이어서 공기 차단력이 크게 저하됨은 물론, 외부의 열기가 내부로 침입할 수 있는 것이어서 단열 효과가 크게 저감되는 단점이 지적된다.In addition, the conventional rubber sealing packing simply seals the thin portion of the blade in the space to greatly reduce the air blocking force, and the external heat can penetrate into the interior, do.
