Specific embodiment
The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes
But it is not limited only to following embodiment.
The purpose of the present embodiment is to provide for a kind of wooden door core fire resistant doorsets, referring to FIG. 1 to FIG. 5, including fireproof door frame
With door leaf 4.The doorframe includes solid framework 1, is wrapped in the U-shaped metal frame 2 in solid framework with doorframe joint, and
It is uniformly arranged in metal frame and is used at least two hinges 3 hinged with doorframe.
The solid framework 1 can directly select conventional fire-resistant composite panel, and two layers of glued board and intermediate process also can be selected
The composite plate of the solid wood layer composition of fire prevention processing, and it is matched by the part that metal frame 2 is wrapped up with metal frame and therewith
It fits closely.
The hinge structure is identical as existing hinge, including the first connecting plate 31, axis 32 and the second connecting plate 33.
2 cross section of metal frame be in concave shape, be aluminium alloy integral structure, for ease of description, be classified as with
The side plate that doorframe connects, the inner panel on the inside of doorframe, and the outside plate on the outside of interior window frame.Inside on the side plate opens up
There is through-hole 21, the strip-shaped hole 22 being connected to through-hole is offered on the inner panel, the through-hole combines to form cross section with strip-shaped hole
L-shaped slot, first connecting plate 31 are bolted in the solid framework in through-hole, the axis and the first connecting plate
With the second connecting plate it is hinged, be placed in strip-shaped hole, second connecting plate with doorframe for being bolted；Here, in order to increase
Add the stability of connection, the present embodiment has also welded concave bottom plate 24 in the metal frame 2 of 21 inside of through-hole, and described
24 both ends of concave bottom plate are respectively welded at 2 inside of metal frame of about 21 through-hole, and 24 inside of concave bottom plate and solid framework 1 are tight
Closely connected conjunction, the bolt then pass sequentially through bolt hole on the first connecting plate, are inserted into solid box body after concave bottom plate, Ji Keshi
The fixation of existing first connecting plate.Second connecting plate 33 can be affixed after the rotation of axis 32 with the first connecting plate, and at this time second
Connecting plate outer surface is flushed with 2 surface of metal frame, in this way, after installing doorframe, when doorframe is closed, between doorframe and doorframe
Macroscopic gap is not present, greatly reduces flare and alters into the danger scurried out.
The door leaf can be the door leaf 4 of vertical hinged door, be also possible to the door leaf of sliding door；On the door leaf with adjacent door leaf
Opposite side is equipped with bound edge component；The bound edge component includes Z-shaped connector 5 and Bar Fastener 6, the Z-shaped connector 5
Middle part is affixed with door leaf side, and one flanging is fixed with door leaf front edge, and another flanging is located at the door leaf back side and towards adjacent
Door leaf, the Z-shaped connector directly can select fire-proof plate to manufacture, and can brush one layer of rubber with pre- hot expansibility on the outside
Layer；Described Bar Fastener one end connects with door leaf dorsal edge, and the other end extends towards adjacent door leaf and is fixed on corresponding Z-shaped
On connector flanging, for offseting with adjacent door leaf dorsal edge.Z-shaped connector 5 and Bar Fastener 6 collectively constitute one will
The groove type for fixing of 4 edge wrap of door leaf extends after the recess edge slightly evagination towards adjacent door leaf, works as door leaf
When 4 closure, it can play the role of and offset on the outside of the groove of adjacent door leaf 4, due to Z-shaped connector flanging and world locking member
6 integral thickness are smaller, therefore when two binding structures are bonded to each other, for existing door leaf directly fits, more
Closely, therefore fireproofing function can be played.The Bar Fastener 6 can be used metal material and be made, on the one hand since it is main
Fixed effect is played, is on the other hand then that can be equipped with returning plate at its edge, makes the Z-shaped connector flanging at the door leaf back side
It is then stuck between Bar Fastener edge and returning plate, to play the role of protecting Z-shaped connector.
In order to improve the fireproofing function of the present embodiment fireproof door leaf structure, and certain Smoke prevention can be played the role of, this
The door leaf 4 is set composite plate structure by embodiment, including two layers of glued board and the intermediate solid wood layer by fire prevention processing, mentions
High flameproof effect；Meanwhile also respectively being inlayed on two flangings of the Z-shaped connector 1 and being provided with the second fire prevention Expandable strip 9, also exist
The outside of the side plate is longitudinally equipped with an arc groove, and card has the first fire prevention Expandable strip 23 in the arc groove.Also, the solid box
Body 1, metal frame 2, hinge 3 and bound edge module outer surface are equipped with fire resistant coating.
Above-described embodiment is only one of preferred embodiments of the present invention, should not be taken to limit the utility model
Protection scope, as long as the utility model body design thought and mentally make have no the change of essential meaning or profit
Color, it is solved the technical issues of it is still consistent with the utility model, the protection scope of the utility model should all be included in
Within.
