Description

door {DOOR}

The present invention relates to a door, and more specifically, to a door having edge covers formed on the front and rear sides of the door to support decorative materials.

Fire doors are structures installed to block the spread of flame or smoke in houses, apartments, factories, offices, and prefabricated temporary buildings, and are mainly used as entrance doors or emergency doors in normal times.

Since these fire doors must block the movement of high-temperature flames or smoke in the event of a fire, they must be made of metal, and if necessary, flame retardant materials, etc. may be added inside.

Conventional fire doors are usually manufactured by attaching sheets to the outer and inner surfaces of a flat fire door to create a fire door with a design requested by the user. Alternatively, the fire door can be designed by attaching a decorative material with a different texture from the metal material to the fire door. In this case, a separate decorative material fixing part must be installed on the edge of the fire door to support the decorative material. These decorative fixing parts are usually installed on fire doors using fastening members such as screws. However, when manufacturing a fire door equipped with a decorative material like this, there is a problem in that the work process is complicated, such as having to install a decorative material fixing part. Additionally, since the decorative material fixing part itself occupies a certain area, there is also a problem that the installation area of the decorative material installed on the fire door becomes smaller. There is also the problem that the overall design of the fire door is not clean due to the decorative fixings.

Therefore, there is a need for various research and development on fire doors equipped with edge covers that allow users to easily attach decorative materials requested to the fire doors.
