Fireproof door and preparing method of fireproof door
The invention provides a fireproof door, which comprises a door leaf inner plate and a door leaf outer plate, wherein the door leaf inner plate comprises an inner plate casing and an inner pressing edge, the inner pressing edge is arranged at the edge of the inner plate casing and outwards extends, the door leaf outer plate comprises an outer plate casing and an outer pressing edge, the outer pressing edge is arranged at the edge of the outer plate casing and inwards extends, the inner pressing edge is in lap joint onto the outer pressing edge, and the inner pressing edge and the outer pressing edge are in riveted connection. The fireproof door is characterized in that the inner leaf inner plate and the door leaf outer plate are fixedly connected at a lap joint position of the inner pressing edge and the outer pressing edge, so that the lap joint position of the inner pressing edge and the outer pressing edge is changed from the traditional welding fixed connection mode into the riveting fixed connection mode, the stability of a connecting structure of the door leaf inner plate and the door leaf outer plate is ensured, meanwhile, the preparing process complexity of the fireproof door is reduced, and the environment pollution caused by the welding connection mode is avoided. The invention also provides a preparing method of the fireproof door.
