Description
본 고안은 방음 방화문에 관한 것으로서, 더욱 상세하게는, 전방판과 후방판을 결합시에 별도의 날개부를 형성하여 결합시키므로 다양한 형태의 문틀과 문을 제조할 수 있는 방음 방화문에 관한 것이다.The present invention relates to a soundproof fireproof door, and more particularly, to a soundproof fireproof door that can manufacture various types of door frames and doors by combining and forming a separate wing at the time of combining the front plate and the rear plate.
종래의 방화문은 두 개의 철판(전방판, 후방판)을 절곡하여 끼워 맞추어 압착하거나, 두 개의 철판을 스폿용접하여 완성하여 사용하였다.Conventional fire doors were used by bending and pressing two iron plates (front plate and rear plate), or by welding two iron plates by spot welding.
그러나, 이러한 종래의 방화문은 문틀과 맞추어 설계해야 하고 문틀의 구조와 맞추어 다양하게 제조가 어려운 문제점이 있었다.However, such a conventional fire door has to be designed in accordance with the door frame and difficult to manufacture a variety of door frame structure.
또한, 방화문의 날개부를 전방판과 후방판으로 절곡하여 제작하였으나, 날개부를 만들기 위해 밴딩하는 부분이 많아 제작이 어렵고 제작비용이 증가하는 요소중에 포함되어 있었다.In addition, it was produced by bending the wing portion of the fire door into the front plate and the rear plate, but many of the bending portion to make the wing part was included among the factors that are difficult to manufacture and increase the production cost.
따라서, 본 고안은 상기 종래의 문제점을 감안하여 안출한 것으로서, 본 고안의 목적은, 전방판과 후방판을 결합시에 별도의 날개부를 형성하여 결합시키므로 다양한 형태의 문틀과 문을 제조할 수 있는 날개부착형 방음 방화문을 제공하는데 있다.Therefore, the present invention has been devised in view of the above-mentioned conventional problems, and the object of the present invention is to form a separate wing portion when combining the front plate and the rear plate, so that various types of door frames and doors can be manufactured. To provide a winged soundproof fire door.
이와 같은 목적을 달성하기 위한 본 고안의 날개부착형 방음 방화문은 전방판과 후방판의 측부에 날개부를 부착하여 문틀과 문짝을 다양하게 제조가 가능하고 별도로 날개부를 부착함으로써, 제조가 쉬운 특징이 있다.The wing-mounted soundproof fire door of the present invention for achieving the above object is possible to manufacture a variety of door frames and doors by attaching the wing to the side of the front plate and the rear plate, and is easy to manufacture by attaching the wing separately. .
