With the abrasion brought, improves its service life and can effectively solve the problem that the problem of background technology proposes.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of single open-type has the fire resistant doorsets of skeleton structure, including doorframe and door leaf, passes through between the doorframe and door leaf
Hinge hinge for fireproof connects in a manner of singly opening, and is connected by fireproof door closer with the top of door leaf in doorframe, the door
Fan is equipped with flame-retardant plywood, fire-proof plate, anti-fire door core board, fire-proof plate and flame-retardant plywood, and the fire prevention successively from the bottom to top
Lining framework is equipped in door panel, the end of the anti-fire door core board is equipped with peripheral frame skeleton.
As a kind of preferred technical solution of the utility model, the door residing for the hinge hinge for fireproof and fire-proof door closer
Reinforcement steel plate is equipped on fan.
As a kind of preferred technical solution of the utility model, fire prevention Expansion sealing is equipped between the doorframe and door leaf
Part.
As a kind of preferred technical solution of the utility model, also by being located at door leaf side between the doorframe and door leaf
Fireproofing door lock locking connection.
Compared with prior art, the utility model has the beneficial effects that：The utility model is by between doorframe and door leaf
Fireproof expansion seal part is set so that has closed structure between doorframe and door leaf, and after fire occurs, fire prevention expansion
Sealing element expansion is enclosed, and the ability of actual fire prevention and protection from fumes is substantially increased, and furthermore, it is understood that by right
Door leaf is transformed, and peripheral frame skeleton and lining framework are added in door leaf, improves integrally-built rigid support intensity, but also
It is provided with reinforcement steel plate, the abrasion that can be brought to avoid long-time service improves its service life.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1 to Figure 3, the utility model provides a kind of fire resistant doorsets of the single open-type with skeleton structure, including door
Frame 1 and door leaf 3 connect between the doorframe 1 and door leaf 3 in such a way that hinge hinge for fireproof 5 is in singly to open, and in 1 He of doorframe
The top of door leaf 3 is connected by fireproof door closer 2, is connected doorframe 1 and door leaf 3 by hinge hinge for fireproof 5, and into
One step makes there is the ability being automatically closed between doorframe 1 and door leaf 3 by the way that fireproof door closer 2 is arranged.
The door leaf 3 from the bottom to top successively be equipped with the flame-retardant plywood 7 of 3mm, the fire-proof plate 8 of 5mm, anti-fire door core board 9,
The fire-proof plate 8 of 5mm and the flame-retardant plywood 7 of 3mm, and lining framework 11, the fire-resistant door core are equipped in the anti-fire door core board 9
