A fire door and the fire door panel used therefor

Abstract

The invention provides a fireproof door and a fireproof door plate used by the same. The fireproof door comprises a door plate and a door frame installed at the periphery of the door plate in a sleeving manner, wherein distance location devices are arranged between the door frame and the door plate of the fireproof door, the distance location devices are uniformly arranged at intervals, buffer structures are arranged at the inner side of the door plate of the fireproof door, and the buffer structures are arranged at the middle positions of the two sides of the door plate respectively. The distance location devices are arranged between the door frame and the door plate of the fireproof door provided by the invention, the distance location devices are uniformly arranged at intervals, and by arranging the distance location devices, difficult opening for the fireproof door due to the own heat-expansion and cold-contraction effect of the fireproof door can be effectively prevented in case of a fire, and the losses of personal safety can be reduced; in addition, the buffer structures are arranged at the inner side of the door plate of the fireproof door, and through arrangements for second-layer buffer structures and selections for the positions of the buffer structures, secondary protection can be effectively carried out. The fireproof door is simple in structure, convenient to operate, low in production cost, and good in fireproof effect.

Description

technical field [0001] The invention relates to the technical field of door manufacturing, in particular to a fireproof door, and also to a fireproof door panel used in the fireproof door. Background technique [0002] Many methods and techniques for manufacturing fire doors and fire door cores have been developed over time. But most of these prior art designs do not lend themselves well to fully automated manufacturing processes. The fire doors currently on the market include a fireproof core board and a fireproof finish covering the fireproof core board. The fireproof core board is made of aluminum silicate wool or expanded perlite wool as the main material. Aluminum silicate wool is the main material, and the smoke produced by it is toxic; the fireproof core board of the fire door uses expanded perlite wool as the main material, and its strength and fireproof combustion performance are poor. [0003] In general, fire doors refer to doors that can meet the requirements o...
