본 고안은 방화문에 관한 것으로, 보다 상세하게는 화재 발생시 열기에 의한 변형을 최소화함과 동시에 도어 안쪽과 바깥쪽 간의 열전달을 최소화 할 수 있도록 형성된 방화문에 관한 것이다.The present invention relates to a fire door, and more particularly to a fire door formed so as to minimize the heat transfer in the event of fire and to minimize the heat transfer between the inside and the outside of the door.
건물의 계단실부분, 복도 또는 승강기의 승강로 부분이나 복층형인 공동주택의 세대안의 층간 바닥 부분에는, 화재 발생시 불길 및 연기가 퍼지는 것을 방지하기 위해 방화문을 설치하도록 규정되어 있다.It is prescribed to install fire doors to prevent the spread of flames and smoke in the event of a fire in the staircase part of the building, in the corridor or in the hoistway of the elevator, or in the inter-floor floor of the multi-storey apartment building.
방화문은 강판 등과 같이 불이 붙지 않는 난연성 재료로 제작되며, 내부에는 열전달 계수를 낮은 재질 예를 들어 발포 우레탄 등이 설치되어 있다.The fire door is made of a flame-retardant material that does not catch fire, such as a steel plate, and a material having a low heat transfer coefficient, for example, foamed urethane, is installed inside.
그런데, 종래의 강판재 방화문은 외관을 형성하는 양쪽 철판 내부에 열전달계수를 낮추기 위해 단순히 단열재가 채워지는 구조이기 때문에, 고온에 접하거나 화염에 접촉하는 경우, 국부적인 온도 차이에 의해 도어 몸체에 비틀림 등의 변형이 발생하였으며, 심한 경우 도어의 개폐가 어려워 인명이나 재산 구조에 어려움을 겪는 경우가 많았다.However, the conventional steel plate fire door is a structure in which the heat insulating material is simply filled in order to lower the heat transfer coefficient inside both steel plates forming the appearance, so that when contacted with a high temperature or flame, the door body is twisted by the local temperature difference In some cases, the door is difficult to open and close, and the life and property structure is often difficult.
본 고안은 상기와 같은 종래 방화문의 문제점을 해결하기 위한 것으로, 고온의 열에 접해도 쉽게 변형되지 않으면서, 문을 통한 열전달을 최소화시킬 수 있는 방화문을 제공하는 데 있다.The present invention is to solve the problems of the conventional fire door as described above, to provide a fire door that can minimize the heat transfer through the door without being easily deformed even in contact with high temperature heat.
