Abstract

The invention discloses a rock wool filling-based isolation device for a fireproof door. The rock wool filling-based isolation device comprises a wall structure, wherein the wall structure comprises afloor, a ceiling and a door post connected between the floor and the ceiling; the fireproof door which is hollow inside and is provided with an opening in the top is hinged to the door post; the fireproof door is filled with rock wool; a seat plate which is in sliding connection with the top surface of the fireproof door is fixed at the bottom of the ceiling; a through hole which communicates with an inner cavity of the fireproof door is formed in the seat plate; a vacuum groove which is positioned above the seat plate and communicates with the through hole is formed inside the ceiling; the fireproof door is a normally closed door which is opened only when a fire occurs and the fireproof door is maintained; the vacuum groove is filled with supplementary cotton; a simulated vacuum environment is formed in the vacuum groove; and a water outlet mechanism is arranged in the ceiling. According to the fireproof door disclosed by the invention, the failure time of rock wool fillers and a core plate in the fireproof door can be delayed, and the heat insulation and fire resistance of the fireproof door are greatly improved.

Description

technical field [0001] The invention relates to the field of fire doors, in particular to an isolation device for fire doors based on rock wool filling. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. [0003] Rock wool is an inorganic external wall insulation material. Because of its A-level combustion performance and fine fiber structure, in the prior art, rock wool fibers are also made into rock wool boards to participate in fire insulation, and the effect is good. Fire doors achieve...
