Abstract

The invention discloses a fireproof door seam covering structure. The fireproof door seam covering structure comprises a door frame and door leaves. The door leaves comprise the left door leaf and the right door leaf, a seam covering plate is arranged on the left door leaf or the right door leaf and comprises a covering plate connected with the outer side of the left door leaf or the right door leaf and a baffle of which the section is in an L shape, one side of the baffle is connected with the covering plate, and the other side of the baffle faces the right door leaf or the left door leaf so that the overall seam covering plate can be in a Z shape. When the door leaves are closed, the baffle can be tightly attached to the right door leaf or the left door leaf so that the seam between the left door leaf and the right door leaf can be closed. Fire can be effectively prevented from spreading, and smoke can be effectively prevented from dispersing.

Description

technical field [0001] The invention relates to a fire door, in particular to a fire door cover seam structure. Background technique [0002] The importance and functionality of fire doors in fire-fighting facilities are getting more and more attention from fire-fighting authorities. When a fire occurs, the fire door channel is the only exit for personnel to escape, and the fire door is an important barrier to prevent the fire from spreading and the smoke from spreading. Therefore, the development of fire door manufacturing and application technology is a very important technology to ensure the safety of personnel, property and safety. [0003] Fire doors are classified according to the materials used, including steel fire doors, steel-wood fire doors, and wooden fire doors. Any type of fire doors will be deformed during processing, installation, and use, and will be more deformed when heated, and collided. The gap between the door leaf and the door leaf becomes larger o...
