In the fireproof wooden door, the fireproof door leaf comprises a door leaf framework, a transverse rib is arranged in the middle of the door leaf framework, panel installation cavities are respectively arranged on the upper side and the lower side of the transverse rib, a plurality of flame retardant material installation cavities which are uniformly distributed up and down are arranged in each panel installation cavity, and flame retardant materials are filled in the flame retardant material installation cavities; transversely arranged separation ribs are arranged between the adjacent flame retardant material mounting cavities; and clamping limiting edges are arranged on the front side edge and the rear side edge of the separation rib.
In the aforesaid fire door is prevented to wooden, both sides are equipped with the door leaf panel respectively around the panel mounting chamber, are equipped with on the door leaf panel inner wall with the spacing limit matched with joint groove of joint, the fire-retardant layer of fire prevention is equipped with in the joint inslot.
In the wooden fireproof door, the side walls around the panel installation cavity are provided with the sealing cavities, and the periphery of the inner wall of the door leaf panel is provided with the flame-retardant sealing rubber strips matched with the sealing cavities.
Compared with the prior art, the fireproof door frame has the advantages that the fireproof grooves corresponding to the fireproof door leaves are formed in the inner wall surface of the door frame body, so that the aim of fire prevention is fulfilled; meanwhile, a group of flame-retardant separation blocks are arranged at the inner side end of the fireproof groove, separation grooves corresponding to the flame-retardant separation blocks are arranged on the side edges of the fireproof door leaves, and when the door leaves are in a closed state, gaps between the door leaves and the door frame are separated into a plurality of independent gaps, so that the fire is prevented from spreading in the whole gap area, the fire spreading area is reduced, the fireproof effect can be effectively improved, and the purpose of double-layer fireproof is achieved. In addition, the door leaf of the utility model consists of a door leaf framework and transverse ribs, and a plurality of mutually independent flame retardant material installation cavities are arranged in the panel installation cavity, thereby reducing the mutual influence of the flame retardant materials and improving the fireproof performance; and, through fire-retardant joint strip and seal chamber cooperation between door leaf panel and the panel installation cavity, further improve fire behavior. The door leaf panel is pre-fixed with the transverse ribs in a clamping mode, so that the door leaf panel is convenient to mount, and the purpose of blocking flame can be achieved. To sum up, the utility model has the characteristics of can effectively improve the fire prevention effect.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A wooden fire door is composed as shown in figures 1 to 6, and comprises a fire door frame 1 and a fire door leaf 2, wherein the fire door frame 1 and the fire door leaf 2 are connected through a hinge 3; the fireproof door frame 1 comprises a door frame body 4, fireproof grooves 5 corresponding to the fireproof door leaves 2 are formed in the inner wall surface of the door frame body 4, and a group of flame-retardant partition blocks 6 are arranged at the inner side end of each fireproof groove 5; each side edge of the fireproof door leaf 2 is provided with a separation groove 7 corresponding to the flame-retardant separation block 6; the separation groove 7 and the flame-retardant separation block 6 are both in a trapezoidal structure.
The fireproof door leaf 2 comprises a door leaf framework 201, a transverse rib 202 is arranged in the middle of the door leaf framework 201, panel mounting cavities 203 are respectively arranged on the upper side and the lower side of the transverse rib 202, a plurality of flame retardant material mounting cavities 204 which are uniformly distributed up and down are arranged in each panel mounting cavity 203, and flame retardant materials are filled in the flame retardant material mounting cavities 204; transversely arranged separation ribs 205 are arranged between the adjacent flame retardant material mounting cavities 204; clamping limiting edges 206 are arranged on the front side edge and the rear side edge of the separation rib 205.
