Definitions

  • the present invention relates to a door mounted on a building, and more particularly to a door having a fireproof function. Background technique
  • a common fire door includes a door leaf and a door cover fixed to the wall body, and the door leaf is hinged on the door cover.
  • the door leaf is composed of a front fire board, a rear fire board and a keel bracket between the two, and a hollow structure is formed between the two layers of the fire board and the keel bracket, so that when the fire is relatively large, the front and rear fire boards are Without support, it is easy to deform, affecting the overall structure of the door leaf and losing the effect of fire prevention. Therefore, soft fillers such as foam are generally filled between the two fireproof panels to support the fireproof panels on both sides, but these fillers are easily decomposed and degenerated in a long time high temperature environment, and even generate smoke, which is safe.

After being filled in the cavity between the two-layer fireproof board and the keel bracket, the front and the fireproof board can be fully supported, and the door leaf can be ensured when the fire is large. It is not deformed and is safe and reliable to use. Moreover, the materials used can be recycled and environmentally friendly.
  • a fireproof cover for sealing the cavity between the front fireproof panel, the rear fireproof panel and the keel bracket is provided along the edges of the front fireproof panel and the rear fireproof panel. In this way, the inside of the door leaf is completely isolated from the outside, and the hot flue gas does not enter the cavity inside the door leaf, which blocks heat and further improves the safety and reliability of fire prevention.
  • the fireproof cover is fixed on the keel bracket by a locking device, the locking device is a relatively extended locking hook disposed on one end of the keel bracket, and the fireproof cover is disposed on the fireproof cover
  • the buckle is composed of a protrusion on the lock hook, and a groove corresponding to the protrusion is arranged at a corresponding position of the buckle. In this way, the fireproof cover can be snap-fitted to the keel bracket by the mutual cooperation of the groove and the protrusion, and the installation tool is not needed, and the on-site assembly is convenient.

  • An expansive fireproof strip is disposed between the door leaf and the door sleeve. After being heated, the fireproof strip will expand to fill the gap between the door leaf and the door cover to prevent the smoke from escaping from the gap between the two, further improving the smoke prevention effect of the fire door.
  • the door leaf is hinged to the door cover by a blind hinge, which can prevent the hinge portion from being damaged by heat and enhance the safety of use of the fire door.
  • a metal veneer or fireproof veneer is arranged on the outer wall of the front fireproof board or the rear fireproof board to protect the fireproof board, and the overall visual effect of the fireproof door can also be increased.
