Description

Double-layer composite wooden fireproof door structure Technical Field The utility model relates to the technical field of fireproof doors, in particular to a double-layer composite wooden fireproof door structure. Background The fireproof door is a door with special functions, is mainly used for playing roles of preventing fire separation and preventing fire from spreading in a building, is a door type with excellent fireproof performance, takes wood as a main frame material, has the texture and the attractiveness of natural wood, enhances the fireproof performance through a special double-layer composite structure design, is generally composed of two layers of different materials, is generally made of high-quality wood subjected to fireproof treatment, has certain strength and decoration, and can resist attack of flame and heat to a certain extent. The inner layer is filled with high-efficiency fireproof heat-insulating materials such as rock wool, glass wool and the like, and the materials have good heat-insulating performance, can effectively prevent heat transfer, delay fire spreading, ensure that the door keeps integrity and heat insulation within a specified time, and meet the corresponding fireproof grade requirement. Fireproof doors are arranged at the positions of the fireproof partitions, the evacuation channels and the stairwells of the building, so that the spread of fire can be effectively delayed, valuable time is strived for personnel evacuation and fire rescue, and the fireproof doors are important facilities for guaranteeing the fire safety of the building. According to the retrieval, in the prior art, chinese patent publication No. CN212958337U discloses a wooden fireproof door, which comprises a door frame and a door leaf, wherein the surface of the door leaf is covered with a fireproof coating, the door leaf is provided with an observation port in a penetrating manner, one side of the door leaf is embedded with first fireproof glass at the opening of the observation port, the other side of the door leaf is rotationally connected with a first baffle for sealing the corresponding observation port, the door leaf is provided with an operation port for a fire-fighting lance to insert in a penetrating manner, one side of the door leaf, where the first baffle is located, is rotationally connected with a second baffle for sealing the operation port, and two locking pieces for locking the first baffle and the second baffle are respectively arranged on the door leaf.
