Description
Technical field
The present invention relates to a field, particularly relate to a kind of fireproof door leaf structure.
Background technology
At present, before and after the steel door leaf of main flow on the market panel generally by welding manner rigidity
Connecting, thus form a door leaf entirety, the steel door leaf bulk strength of this structure is higher.
But when steel door leaf internal-external temperature difference is excessive, door skin and door leaf backboard can be because of temperature distortions
Amount difference and produce buckling deformation, cause door leaf fire prevention lost efficacy, had a strong impact on the attractive in appearance of door leaf.
Summary of the invention
The invention aims to overcome the deficiency of above-mentioned background technology, it is provided that a kind of fireproof door leaf
Structure.
In order to realize object above, a kind of fireproof door leaf structure that the present invention provides, including door leaf face
Plate and door leaf backboard, on described door skin, the corresponding lockset side installing lockset is provided with buckle, described
Buckle is strip structure, and described buckle is arranged along the length direction of described lockset side, described door leaf
On backboard, the position of corresponding described buckle is provided with the catching groove matched with described buckle, and described catching groove is also
Strip structure；The lockset side of described door skin is by described buckle and described catching groove and described door
The respective side clamping of fan backboard, on described door skin, the corresponding hinge side of hinge of installing is with described
The respective side of door leaf backboard is welded to connect；Described buckle is embedded with anti-with the wedging position of described catching groove
Fire sealing strip, described fire proof sealing strip is strip structure, and described fire proof sealing strip is along described buckle
Length direction is arranged；The position of the internal corresponding described lockset side of described door skin is provided with reinforcement internal skeleton,
It is provided with fire-proof heat insulation board between described reinforcement internal skeleton and the lockset side of described door skin；Described door leaf
It is also filled with PLASTIC LAMINATED in the cavity that panel and described door leaf backboard are surrounded.
By using interface arrangment to realize the lockset side of door skin and the respective side of door leaf backboard
Connect, so, when door skin and door leaf backboard cause dilatancy amount because door leaf internal-external temperature difference is huge
Time different, can produce between door skin with door leaf backboard relative slidably, such that it is able to counteracting
The dilatancy amount of sheet material, and then avoid the generation of buckling deformation；Meanwhile, by door skin
The position of internal corresponding lockset side adds reinforcement internal skeleton, is greatly improved the lockset side of door skin
Intensity, then coordinate the fire proof sealing strip added and fire-proof heat insulation board effectively intercept heat to be delivered to
In the lockset side of door skin, it is thus possible to make the lockset side of door skin be not easy flexural deformation,
And then further avoid the generation of buckling deformation.
In such scheme, described buckle and described door skin are integral type structure.
In such scheme, described catching groove and described door leaf backboard are integral type structure.
In such scheme, it is groove structure outside described buckle and the wedging position of described catching groove, institute
State fire proof sealing strip to be embedded in described groove structure.Groove structure by design so that prevent fires close
The installation of strip of paper used for sealing is more convenient.
In such scheme, described fire proof sealing strip is U-shaped structure, and the fire prevention of described U-shaped structure is close
The opening of strip of paper used for sealing is arranged towards described groove structure.By fire proof sealing strip being designed as U-shaped structure,
So fire proof sealing strip seals tight and difficult drop-off.
In such scheme, the width D of described fire-proof heat insulation board and the lockset side of described door skin
Width consistent.
In such scheme, the hinge side of described door skin is provided with inside right-angle bending structure.
Design inside right-angle bending structure by the hinge side at door skin, be so easy to door skin
And the installation location between door leaf backboard.
In such scheme, described right-angle bending structure is strip structure.
In such scheme, described right-angle bending structure is arranged along the length direction of described hinge side.
In such scheme, described right-angle bending structure and described door skin are integral type structure.
Technical scheme has the benefit that
1, by using interface arrangment to realize the lockset side of door skin and the respective side of door leaf backboard
Connection, so, when door skin and door leaf backboard cause dilatancy because door leaf internal-external temperature difference is huge
When amount is different, can produce between door skin with door leaf backboard relative slidably, such that it is able to support
Disappear the dilatancy amount of sheet material, and then avoids the generation of buckling deformation；
2, by adding reinforcement internal skeleton in the position of the internal corresponding lockset side of door skin, can significantly carry
The intensity of the lockset side of high door skin, then coordinate the fire proof sealing strip added and the fire-proof heat insulation board can
In intercept heat is delivered to the lockset side of door skin effectively, it is thus possible to make the lockset of door skin
Side is not easy flexural deformation, and then further avoids the generation of buckling deformation；
3, by the groove structure of design so that the installation of fire proof sealing strip is more convenient；
4, by fire proof sealing strip is designed as U-shaped structure, such fire proof sealing strip seals tight and not
Easy to fall off；
5, design inside right-angle bending structure by the hinge side at door skin, be so easy to door
Installation location between leaf plank and door leaf backboard.
