The present invention relates to a fire door structure and a method of manufacturing the fire door structure capable of finishing with a beautiful finishing material to produce an appearance that is out of the shape of a hard fire door.

In general, fire doors are mainly used as entrance doors or emergency doors of general houses, buildings, apartments, factories, offices, prefabricated temporary buildings, and the like. It is made of a solid material made of metal so that it does not spread into the furnace, and it requires physical property that the door or emergency door should not be burned or deformed by the strong heat inside.

In particular, modern buildings, apartments, and apartment-type factories are built on high-rise buildings, increasing the risk of fire, and if people do not prevent the spread of flames and smoke during a fire, people living on high-rises are suffocated by smoke choking or burning. Because a lot of life and property damage is caused by the role of the fire door is very important.

Such a fire door is usually produced by forming a non-flammable or flame-retardant reinforcing material between the inner panel and the outer panel. Specifically, the general fire door is mainly composed of a steel fire door consisting of the front plate (front panel), the rear plate (rear panel) and the internal filler honeycomb, and recently, the flame-retardant synthetic resin plate or flame-resistant wood plate and the internal filler on the back It is mainly made of flame-retardant doors, which are made of honeycomb and made of a frame member.

However, the conventional fire doors do not seal the two panels in an airtight manner when joining the front panel and the rear panel, so that condensation occurs between the two panels, and thus, durability and insulation are inferior. Not only the manufacturing cost increases but also the construction work is difficult, there is a problem that the work efficiency is lowered.

In addition, the conventional fire door has a problem that the coupling member such as bolts or nuts are exposed to the outside when the front panel and the rear panel is coupled to the outside to damage the appearance, the conventional fire door has a limitation in implementing a beautiful appearance.
