Embodiment 1

[0016] Embodiment 1: see figure 1 , a split-type fire door cover seam structure, including a door frame and a door leaf, the door leaf includes a left door leaf 1 and a right door leaf 2. Both the left door leaf 1 and the right door leaf 2 are composed of a frame body 4 and an inorganic fireproof core material board 5 inside the frame body 4. The frame body 4 is stamped and formed by a metal composite board, and the metal composite board includes two metal plates and a The adhesive between two metal plates and bonding the two metal plates together, in specific implementation, the metal plate is made of stainless steel plate, which has better stability.

[0017] On the left door leaf 1 and the right door leaf 2, a cover seam plate 3 is respectively closely attached, and the two cover seam plates 3 are respectively located on the inside and outside of the door leaf. The gap between the door leaf 1 and the right door leaf 2 is closed. The cover seam plate 3 is in-line, and is f...

Embodiment 2

[0020] Example 2, see figure 2 The difference from the implementation of your 1 is that a connection plate 7 is provided on the opposite sides of the two cover seam plates 3, so that the overall section formed by the cover seam plate 3 and the connection plate 7 is T-shaped, and the two connection plates 7 are far away from the cover. One side of the slit plate 3 is bent in a direction away from each other, and the two cover slit plates 3 are respectively fastened together with the left door leaf 1 and the right door leaf 2 through the connecting plate 7, and the adjacent end faces of the left door leaf 1 and the right door leaf 2 are fixed together. Covering: it can better protect the adjacent sides of the left door leaf 1 and the right door leaf 2, so that the cover seam plate 3 can stably seal the gap between the left door leaf 1 and the right door leaf 2, so as to prevent the spread of fire and smoke diffusion. When the door leaf was closed, the cover seam plate 3 on the...

Abstract

The invention discloses a split crevice cover structure of a fire door. The structure comprises a door frame, a left door leaf and a right door leaf. Each of the left door leaf and the right door leaf is composed of a frame and an inorganic fireproof core plate arranged within the frame. A crevice cover plate is attached to each of the left door leaf and the right door leaf. The two crevice cover plates are disposed inside and outside the door leaves, respectively. When the door leaves are closed, the crevice cover plates can cover a crevice between the left door leaf and the right door leaf from inside and outside of the door leaves, respectively. Each crevice cover plate comprises a metal frame and an inorganic fireproof core plate filling the metal frame; the inorganic fireproof core plate is connected with the metal frame through high-temperature-resistant glue. The split fire door crevice cover structure has the effect of preventing fire spread and smoke spread.

Description

technical field [0001] The invention relates to a fire door, in particular to a cover seam structure of a split fire door. 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 becom...
