The respective side of backboard is welded to connect；The wedging position of the buckle and the catching groove is embedded with fire proof sealing strip, the fire prevention
Sealing strip is strip structure, length direction arrangement of the fire proof sealing strip along the buckle；It is right inside the door skin
Answer the position of the lockset side to be provided with to strengthen being provided between in-seam, the lockset side of the reinforcement in-seam and the door skin
Fire-proof heat insulation board；Fire-proof plate is also filled with the cavity that the door skin is surrounded with the door leaf backboard.
The connection of the lockset side of door skin and the respective side of door leaf backboard is realized by using interface arrangment, this
Sample, when door skin causes dilatancy amount different from door leaf backboard because door leaf internal-external temperature difference is huge, door skin and door leaf
It can be produced between backboard relatively slidably, so as to offset the dilatancy amount of sheet material, and then avoid buckling deformation
Generation；Meanwhile, reinforcement in-seam is added by the position of the correspondence lockset side inside door skin, door leaf face is greatly improved
The intensity of the lockset side of plate, then coordinate the fire proof sealing strip added and fire-proof heat insulation board effectively intercept heat can be delivered to door
In the lockset side of leaf plank, so as to make the lockset side of door skin be not easy flexural deformation, and then further keep away
The generation of buckling deformation is exempted from.
In such scheme, the buckle is integral type structure with the door skin.
In such scheme, the catching groove is integral type structure with the door leaf backboard.
In such scheme, the buckle is with being groove structure, the fire proof seal on the outside of the wedging position of the catching groove
Bar is embedded in the groove structure.Pass through the groove structure of design so that the installation of fire proof sealing strip is more convenient.
In such scheme, the fire proof sealing strip is U-shaped structure, the opening court of the fire proof sealing strip of the U-shaped structure
Arranged to the groove structure.By the way that fire proof sealing strip is designed as into U-shaped structure, such fire proof sealing strip sealing is tight and is difficult
Come off.
In such scheme, the width D of the fire-proof heat insulation board is consistent with the width of the lockset side of the door skin.
In such scheme, the hinge side of the door skin is provided with inside right-angle bending structure.By in door leaf
Inside right-angle bending structure is designed in the hinge side of panel, is so easy to the installation between door skin and door leaf backboard to determine
Position.
In such scheme, the right-angle bending structure is strip structure.
In such scheme, length direction arrangement of the right-angle bending structure along the hinge side.
In such scheme, the right-angle bending structure is integral type structure with the door skin.
The beneficial effect that technical scheme is brought is：
1st, the connection of the lockset side of door skin and the respective side of door leaf backboard is realized by using interface arrangment, this
Sample, when door skin causes dilatancy amount different from door leaf backboard because door leaf internal-external temperature difference is huge, door skin and door leaf
It can be produced between backboard relatively slidably, so as to offset the dilatancy amount of sheet material, and then avoid buckling deformation
Generation；
2nd, reinforcement in-seam is added by the position of the correspondence lockset side inside door skin, is greatly improved door skin
Lockset side intensity, then coordinate the fire proof sealing strip added and fire-proof heat insulation board effectively intercept heat can be delivered to door leaf
In the lockset side of panel, so as to make the lockset side of door skin be not easy flexural deformation, and then further avoid
The generation of buckling deformation；
3rd, the groove structure of design is passed through so that the installation of fire proof sealing strip is more convenient；
4th, by the way that fire proof sealing strip is designed as into U-shaped structure, such fire proof sealing strip sealing is tight and difficult for drop-off；
5th, by designing inside right-angle bending structure in the hinge side of door skin, so it is easy to door skin and door
Fan the installation positioning between backboard.
