Description
Technical field
The present invention relates to fire resistant doorsets, specifically a kind of steel heat insulation fireproof door.
Background technology
Fire resistant doorsets refer to the door that can meet the requirement of fire stability, integrality and thermal insulation within a certain period of time.It is located at
Between fire compartment, at the fire separation with certain fire resistance such as emergency staircase, vertical shaft, gas-distributing motor room.Except having
Outside the effect of common door, with more the effect for preventing fire spreading and flue gas diffusion, the climing of the intensity of a fire can be within a certain period of time prevented
Prolong, it is ensured that evacuating personnel.
In existing fire resistant doorsets, its door leaf structure is by the way of hollow door leaf packing material, and packing material is usually swollen
Swollen perlite etc..Because design structure problem, such fire resistant doorsets deflection are larger, it is difficult to prevent the seam of the intensity of a fire and flue gas from door
Overflowed in gap, so that fire resistant doorsets entirety fire resistance is not high, the fire-resistance time is not long.
The content of the invention
The technical problems to be solved by the invention are cannot to prevent the seam of the intensity of a fire and flue gas from door for existing fire resistant doorsets
The problem overflowed in gap, and the problem that fire resistant doorsets back-fire relief on the whole or resistance to elevated temperatures are not easily deformed by force, there is provided a kind of
It is comprehensive with fire-proof function, temperature distortion after can not only preventing door body from catching fire can also effectively prevent the intensity of a fire and flue gas from overflowing
The steel heat insulation fireproof door for going out.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of steel heat insulation fireproof door, including doorframe, door leaf, are connected, on door leaf between doorframe and door leaf by hinge
Handle and door lock are provided with, fire-proof door closer is provided between doorframe and door leaf；
The door leaf includes skeleton and door skin, and skeleton and door skin are molded by cold-rolling galvanization steel plate rolling, door
Leaf plank is coated on skeleton outside and forms the flat box body of two-layer, and the flat box body of two-layer is interior to irrigate composite fire door core material respectively,
Form the main body of two-layer door leaf, the main body of door leaf described in two-layer forms a whole door leaf, and door leaf described in two-layer main body it
Between have a gap, formed in the middle of be the door leaf of hollow form, the lower end of the door leaf of the correspondence hollow part is provided with air admission hole, door
The upper end of fan and side are provided with steam vent；
The crack between a door and its frame of the medial surface of the door leaf two fans door leaf corresponding with lateral surface, is respectively arranged with lid seam plate.
Using the present invention of above-mentioned technical proposal, compared with prior art, its advantage is：
The composite fire door core material of filling in door leaf（It is anti-fire door core board after shaping）, directly it is poured in door skin
On, make skeleton, door skin and the anti-fire door core board of door leaf be an entirety into consolidating；Double-deck anti-fire door core board makes in the middle of door leaf
Into hollow state, even if catch fire temperature can be allowed to be colded and heat succeed each other in door circulation, make door leaf surface temperature isolation, it is outside constant
Shape, can significantly reach fire-proof and thermal-insulation effect；In addition, having installed lid seam plate additional between door leaf, can preferably prevent
The intensity of a fire or smog spread.
Preferably, the present invention further technical scheme is：
The watchcase of doorframe is molded by cold-rolling galvanization steel plate rolling, casting cement mortar in watchcase；Cement bonded sand inside doorframe
Slurry can be using nontoxic fire proofing material as main raw material(s), even if catch fire being heated, doorframe does not allow yielding, surface yet
Temperature will not be too high.
Doorframe posts fire-proof expansion seal strip with the medial surface contact site dress of door leaf；It is provided with two end side surfaces of door leaf
Fire prevention notch, fire prevention channel is intraoral to be inlaid with fire-proof expansion seal strip；The intensity of a fire can preferably be prevented by fire-proof expansion seal strip
With spreading for smog.
Lid seam plate is made up of cold-rolling galvanization steel plate frame, the composite fire door core material for being poured in cold-rolling galvanization steel plate inframe,
On door leaf, dress posts fire-proof expansion seal strip to lid seam plate weld between lid seam plate and door leaf.Lid seam plate is using basic with door leaf
Identical structure, and be directly welded on door skin, further enhancing door leaf intensity.
The steam vent that door leaf side is set is located at the position for installing hinge；Air circulation is so more conducive to, hinge is protected, plus
The connection effect of strong door leaf and doorframe.
Hinge is hinge for fireproof；The door lock is Fire-proof lock；Hinge, the lock made by fire proofing material, its mass action can
To reach good fire-proof and thermal-insulation effect.
Fire-proof door closer is provided between doorframe and door leaf；Fire-proof door closer effectively can in time close door leaf, blocking fire
Gesture, smog and hot gas.
