Embodiment 1

[0029] figure 1 A schematic diagram of the fire door structure 010 provided in this embodiment. Please refer to figure 1 , The fireproof door leaf structure 010 provided in this embodiment includes a door leaf panel 100 , a door leaf back plate 200 and a packing column 300 .

[0030] The door panel 100 and the door back panel 200 can be matched by means of welding or buckle connection. In this embodiment, the door panel 100 and the door back panel 200 are fitted together by welding. The door panel 100 and the door back panel 200 jointly form a stuffing chamber.

[0031] Packed column 300 includes bundled mesh 310 and packing 320 . The beam net 310 is made of iron wire, and the filler 320 can use fireproof materials such as asbestos. The filler 320 is filled into the bundle-type mesh 310 , thereby forming the filler column 300 . A plurality of packing columns 300 are disposed within the packing cavity. The packing column 320 extends along the vertical direction of the pa...

Abstract

The invention relates to the technical field of furniture and discloses a fireproof door leaf structure. The fireproof door leaf structure comprises a door leaf face plate, a door leaf back plate matched with the door leaf face plate and multiple filler columns, wherein the door leaf face plate and the door leaf back plate jointly define a filler cavity, the multiple filler columns are arranged inthe filler cavity, each filler column comprises a shape retaining net and filler located in the shape retaining net, the filler columns extend in the vertical direction of the filler cavity, and themultiple filler columns are arranged at intervals in the horizontal direction. The fireproof door leaf structure avoids deformation caused by expansion of the filler after being heated.

Description

technical field [0001] The present application relates to the technical field of furniture, in particular to a fireproof door leaf structure. Background technique [0002] Traditional fire doors realize the fire prevention function by adding fireproof materials inside the door leaf. [0003] At that time, after the traditional fireproof door was heated, the fireproof material added in the door leaf would expand and squeeze the door leaf, resulting in deformation of the door leaf. After the door leaf is deformed, it will affect the opening or closing of the fire door, and it will also affect the fire resistance of the fire door, posing a safety hazard. Contents of the invention [0004] The embodiments of the present application provide a fireproof door leaf structure, which will not be deformed due to the expansion of the filler after being heated. [0005] In order to achieve the above-mentioned purpose, the embodiments of the present application adopt the following tec...
