Description

Heat-insulation glass fireproof door

Technical Field

The utility model relates to a prevent fire door, especially relate to a fire door is prevented to insulating glass.

Background

In general, a fire door refers to a door having fire resistance properties. The fire door plays a role in gaining time for people to escape from a fire, preventing the spread of the fire, delaying the spread of the fire and resisting the fire for a certain time. In the traditional domestic process, a galvanized plate or a stainless steel plate is mainly used as a raw material, and after bending and forming, a frame of the fireproof glass door is manufactured, and a structure of fireproof glass is additionally arranged in the middle. The fireproof door with the structure has the advantages that the fireproof time is short, flame and smoke easily enter the room through gaps around the door frame and the door leaf, and when a user is positioned on the back fire surface of the fireproof door, if the back fire surface of the fireproof door is touched carelessly, the user can be scalded due to the heat conduction effect.
