방화문의 힌지편 보강장치{Device for reinforcing hinge of fire proof door}FIELD OF THE INVENTION [0001] The present invention relates to a hinge reinforcement device for a fire door,

본 발명은 방화문의 힌지편 보강장치에 관한 것으로, 더욱 상세하게는 방화문의 상부프레임과 하부프레임상의 힌지편 설치위치에 장착된 상태에서 힌지편과 체결되도록 함으로써 방화문의 자체 중량에 의하여 힌지편이 뒤틀리지 않도록 하고, 화재발생시 뜨거운 열기에 의하여 강도(强度)가 약화되더라도 힌지편이 뒤틀리거나 변형되지 않도록 하여 방화문의 개폐동작이 안정적으로 이루어질 수 있도록 함으로써 사용상의 안정성을 크게 향상시킬 수 있도록 한 방화문의 힌지편 보강장치에 관한 것이다.
The present invention relates to a hinge reinforcement device for a fire door, and more particularly, to a hinge reinforcement device for a fire door that is fastened to a hinge piece in a state in which the hinge piece is mounted on an upper frame of a fire door and a hinge piece on a lower frame, So that the opening and closing operation of the fire door can be stabilized by preventing the hinge member from being twisted or deformed even if the strength is weakened due to hot heat in the event of a fire, thereby enhancing the stability of the hinge. ≪ / RTI >

일반적으로, 방화문(防火門)은 건물의 현관이나 비상계단 출입구에 설치되어 건물 등에서 화재가 발생하는 경우에 화염 및 유독가스의 유입을 차단하고 뜨거운 열기를 일정 시간 동안 막아주어 입주자들을 보호하기 위한 것이다.Generally, the fire door is installed at the entrance of a building or an emergency stairway to prevent flames and toxic gas from entering the building, and to protect the occupants by blocking hot heat for a certain period of time .

이와 같은 방화문을 개폐시키기 위한 수단으로서, 방화문의 상하부에는 힌지편이 방화문의 개폐방향으로 회동가능하게 설치되고, 방화문이 설치되는 문틀에는 상기 힌지편에 끼워지는 지지부재가 고정되게 설치되도록 구성된다.As a means for opening and closing the fire door, a hinge piece is rotatably installed at the upper and lower portions of the fire door in the opening and closing directions of the fire door, and a door member to which the fire door is installed is provided with a support member fitted to the hinge piece.

한편, 이와 같은 방화문에서 힌지편이 별도의 구조물 없이 방화문을 구성하는 상부프레임과 하부프레임에 설치되는 경우에는 방화문의 자체 중량에 의하여 힌지편이 뒤틀리거나 화재발생시 뜨거운 열기에 의하여 강도(强度)가 약화되면서 힌지편이 뒤틀리거나 변형됨에 따라 방화문의 개폐동작이 안정적으로 이루어지 않게 되어 사용상의 안정성이 크게 떨어진다는 심각한 문제가 있다.In the case where the hinge part is installed in the upper frame and the lower frame constituting the fire door without the separate structure, the hinge part is twisted due to the own weight of the fire door or the strength is weakened due to the hot heat when the fire occurs, There is a serious problem that the opening and closing operation of the fire door is not stably performed as the side is twisted or deformed and the stability of the use is greatly reduced.

이와 같은 문제점을 개선하기 위한 기술로서, 대한민국 등록실용신안공보 등록번호 제20-0317333호(명칭: 방화문용 힌지결합장치, 이하 '선행기술'이라 함)가 제안되었다.As a technique for solving such a problem, Korean Registered Utility Model Registration No. 20-0317333 (name: hinge coupling device for fire door, hereinafter referred to as "prior art") has been proposed.

상기 선행기술은 '방화문의 내부패널 우측면 상하부에 도어힌지가 체결고정되되, 문틀의 밀착단 내측 상하부에 힌지보강재가 설치되도록 구성되는 것'으로서, 상부면과 좌우측면에 날개부가 형성된 방화문을 문틀로부터 개폐시 간섭이 발생되지 않도록 이루어진 방화문 개폐수단인 힌지장치를 이용하여 문틀에 고정시킴으로써 방화문의 주기능인 문틀과의 밀폐력을 높이도록 하고, 힌지장치의 위치조정이 가능하여 조립성을 향상시킬 수 있도록 한 것이다.In the prior art, a door hinge is fastened and fixed to the upper and lower portions of a right side of an inner panel of a fire door, and a hinge reinforcement is provided on the upper and lower portions inside the fastening end of the door frame. It is possible to adjust the position of the hinge device so as to improve the assemblability by fixing the door to the door frame by using a hinge device which is a fire door opening / will be.

그러나, 이 같은 선행기술에서는 힌지보강재가 문틀의 밀착단 내측 상하부에 설치되기 때문에 방화문 자체하중의 분산력이 떨어지는 것은 물론, 화재발생시 방화문과 문틀 사이로 유입되는 뜨거운 열기에 노출될 우려가 높기 때문에 안정성 또한 불량하다는 심각한 문제가 있는 것이다. However, in this prior art, since the hinge reinforcement is installed at the upper and lower portions inside the fastening end of the door frame, the fire resistance of the fire door itself is not only low, but also the safety is high because there is a high risk of being exposed to hot heat flowing between the fire door and the door frame. There is a serious problem.
