When the fire resistant doorsets are used, door leaf 1 is installed on doorframe 2 by being arranged on the hinge for fireproof 6 of the side of door leaf 1.When
When meeting with fire, because the 3~5mm of both sides of door leaf 1 thick fireproof panel 7 has stronger non-deformability；Hollow type fire prevention core
The inside configuration of plate 10, the two-layer 5mm thickness phosphorus magnesium fire prevention of setting strengthen central layer 11 and two-layer 25mm thickness pore magnesite foam concrete every
Hot central layer 13, with stronger non-deformability and relatively low heat conductivity；Two-layer strengthens central layer 11 and two-layer heat-insulation core plate
13, the inside configuration gap of hollow type fireproof core board 10 constituted with space bar 9, the pearlite inorganic fire proofing 15 of filling has
There are stronger heat-insulating capability and comprcssive strength so that whole thermal insulation of the door leaf 1 in fire process is good, and deflection is little.And,
This Spaced filling structure of door leaf 1, reduces the corrosion failure that fire-resistant door core material opposite house fans 1 top layer steel plate, extends
The service life of fire resistance steel door.In addition, strengthening the contiguous block 12 arranged between central layer 11 and heat-insulation core plate 13, door is improved
The stability of 1 inside interlayer structure is fanned, makes the combination between the inner. layers central layer of door leaf 1 more firm, effectively extended in fire
The fire-resistance time.The noble gases of the inside filling of interval hollow structure 14 between two-layer heat-insulation core plate 13, contribute to further
The heat-proof quality of stable door leaf 1, and with the effect of reduction room noise.
It is that the two ends of fireproof core board 10 are arranged, handed over by Waterproof gum by three layers of phosphorus magnesium PLASTIC LAMINATED 16 and two-layer cement board 17
Staggered floor folds the fire prevention side plate 8 of composition, is effectively combined phosphorus magnesium PLASTIC LAMINATED 16 and cement board 17, being capable of preferably reinforced door
Fan periphery non-deformability under the high temperature conditions.In order to avoid door leaf periphery occur deformation first occurs under high temperature of fire, affect whole
The problem of individual door leaf effect of heat insulation.
The partition adjustable plate 9 arranged between the end of fireproof core board 10 and both sides fire prevention side plate 8, in fireproof core board 10 and fire prevention
When filler is heated and is deformed in side plate 8, the expansion energy of fire prevention filler can be to a certain extent absorbed, so as to
Reduce door leaf deflection in a fire, reach the purpose for preventing fire spreading within a certain period of time, play preferably fire prevention effect
Really, and slow down the intensity of a fire spread and flue gas diffusion.The circular or strip heat conduction of the bottom surface of groove 18 arranged on doorframe 2
Hole, when door leaf is heated, contributes to conduction of the heat to doorframe, to strengthen the effect of heat insulation of doorframe and door leaf junction, effectively
Slow down further spreading for the intensity of a fire.
