Zusammenfassung:The present invention relates to a multi-functional door device. More specifically, a door circumferential frame and a door support frame configuring the door device have improved strength as compared with the existing door circumferential frame and the door support frame and are manufactured by using aluminum which has the reduced weight and is an incombustible material. The present invention relates to a technique, wherein at least one among the door circumferential frame and the door support frame is manufactured to have an inner hollow structure through an extrusion method to reduce the weight thereof, and the inner structure is improved to lower own thermal conductivity of metal to thermally insulate a door and blocking a sound. 본 발명은 다기능 도어장치에 관한 것으로, 구체적으로는 도어장치를 구성하는 도어테두리틀과 도어지지틀을 기존에 비해 강도가 높은 반면 경량이고 불연 재질인 알루미늄을 사용하여 제작하되, 도어테두리틀과 도어지지틀 중 어느 하나 이상은 압출공법을 통해 내부가 비어 있는 중공구조로 제작하여 무게를 경감시키고, 내부구조를 개선하여 금속특유의 열전도율을 낮출 수 있도록 하여 단열과 동시에 방음기능이 발휘될 수 있도록 한 기술에 관한 것이다.
