"upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

As shown in the figure, the utility model provides a bidirectional door sealing structure, which comprises a door frame 1, wherein a door leaf 2 is arranged in the door frame 1, one side of the door leaf 2 is connected with the door frame through a fireproof hinge 3, the other side of the door leaf is provided with a fireproof lock 4, and the fireproof lock 4 is a CB-SIA fireproof lock. Expanded graphite 6 is arranged on both sides and the upper side of the inside of the door leaf 2, and a door leaf panel is arranged on the outer side of the door leaf 2.

When a fire disaster occurs, the expanded graphite 6 is heated and expanded at an excessively high temperature, and the door leaf panel positioned at the outer side of the expanded graphite 6 is propped open when the expanded graphite 6 expands, so that gaps between the door leaf 2 and the door frame 1 are sealed, the fire disaster is prevented from spreading, and harm to human bodies caused by early-stage dense smoke, toxic gas and hot gas during the fire disaster is prevented.

The door frame 1 is made of a cold-rolled hot-dip galvanized steel sheet with the thickness of 1.2mm, and the cold-rolled hot-dip galvanized steel sheet has good oxidation resistance, does not oxidize or rust in the use process, and has long service life. The cold-rolled hot-dip galvanized steel sheet has good processability and can meet the processing requirements of rolling, stamping forming, bending and other forms.

The thickness of the door leaf 2 is 50mm, and the perlite fireproof plate 5 is arranged inside the door leaf 2. The perlite fireproof plate 5 is a novel fireproof door core filling material which is prepared by using expanded perlite and a pre-buried framework as binders by using applicable adhesives and through the pressure effect. Has 1) natural environment protection, no toxicity and no radioactivity; 2) Fireproof, dampproof and corrosion-resistant; 3) Light weight, heat insulation, sound absorption and good heat preservation; 4) Attractive, economical and convenient; 5) The cutting and planing machine has the characteristics of being capable of cutting and planing, having higher plasticity and meeting different requirements of practical application.

The fireproof hinge 3 between the door frame 1 and the door leaf 2 is a bidirectional hinge, so that the door leaf 2 can be ensured to open in two directions. And the fireproof hinge 3 and the fireproof lock 4 positioned on the opposite side of the fireproof hinge 3 on the door leaf 2 are made of fireproof materials, so that the original shape can be kept at high temperature, and the deformation of the fireproof hinge is not caused by high temperature, so that the use of the door leaf is not affected.

The two sides and the upper part of the perlite fireproof plate 5 are provided with the expanded graphite 6, and the expanded graphite 6 is not only a carbon source in an expansion system, but also a heat insulation layer, can effectively insulate heat, and has the characteristics of low heat release efficiency, small mass loss and less generated smoke in a fire disaster. The expanded graphite 5 is a good fireproof safety material, and can be made into fireproof sealing strips, fireproof blocking materials, fireproof rings and the like according to the characteristics of the expanded graphite 5. When a fire occurs, the expanded graphite 6 expands under heat at a high temperature, and when the expanded graphite 6 expands, the fourth door panel 10 and the fifth door panel 11 located outside the expanded graphite 6 are pushed open to seal the gap between the door leaf 2 and the door frame 1.
