Description

High leakproofness modularization steel prevents fire door Technical Field The utility model relates to the technical field of fireproof doors, in particular to a high-tightness modularized steel fireproof door. Background Steel fire doors refer to doors that meet the requirements of fire stability, integrity, and thermal insulation over a period of time. The fire-proof partition is arranged between fire-proof partitions, evacuation stairways, vertical shafts and the like, has certain fire resistance, has the function of preventing fire from spreading and smoke from spreading besides the function of a common door, and can prevent the fire from spreading within a certain time so as to ensure personnel evacuation. However, the existing steel fireproof doors are all of an integrated structural design, and in public places (such as shops and staircases), the fireproof doors can be damaged due to manual violent damage (such as lock picking and impact), or cat eyes, doorbell and the like are additionally arranged on the fireproof doors in a violation manner to damage the fireproof structure of the doors, so that the fireproof doors lose fire resistance function or influence the fire resistance function in a fire disaster. Disclosure of Invention The utility model aims to solve the technical problem of providing a high-tightness modularized steel fireproof door, which is in modularized design and can directly replace damaged plates so as to solve the problem in the background technology.
