Abstract
The invention relates to a steel heat insulation fireproof door. Each door leaf of the fireproof door comprises a framework and a door leaf panel; each of the frameworks and the door leaf panels is formed by cold rolled galvanized steel plates through rolling; each door leaf panel covers the outer side of the corresponding framework to form a two-layer flat box body; composite fireproof door core materials are injected into each two-layer flat box body; main bodies of two-layer door leaves are formed; the main bodies of the two-layer door leaves form an integral door leaf; a gap exists between the main bodies of the two-layer door leaves; the door leaves with the hollow middles are formed; an air inlet hole is formed in the lower end, corresponding to the hollow part, of each door leaf; the upper end and the side end of each door leaf are provided with exhaust holes; and the inner side surface and the outer side surface of each door leaf are provided with seam covering plates corresponding to door seams of the two door leaves. The steel heat insulation fireproof door has the advantages that the problem that the existing fireproof door cannot prevent fire and smoke from overflowing through the door seams; the integral flame-resistant or high-temperature-resistant performance of the fireproof door is poor; and the door can easily deform. The steel heat insulation fireproof door has the advantages that the all-around fireproof function is realized; the heated deformation of the door body after the fire catching can be prevented; and the flame and smoke overflowing can also be effectively prevented.
Description
Technical field
The present invention relates to labeled door, specifically a kind of steel heat insulation fireproof door.
Background technology
Labeled door refers to the door that can meet fire stability, integrality and thermal insulation within a certain period of time and require.Fire separation place that it is located between fire compartmentation, emergency staircase, vertical shaft, gas-distributing motor room etc. have certain refractoriness.Except the effect with common door, have more the effect stoping fire spreading and flue gas diffusion, spreading of the intensity of a fire can be stoped within a certain period of time, guarantee evacuating personnel.
In existing labeled door, its door leaf structure adopts the mode of hollow door leaf packing material, and packing material is generally expanded perlite etc.Due to project organization problem, such labeled door deflection is comparatively large, not easily stops the intensity of a fire and flue gas to overflow from the gap of door, so that the overall fire resistance of labeled door is not high, and the fire-resistance time is not long.
Summary of the invention
Technical problem to be solved by this invention is, for the problem that the intensity of a fire and flue gas cannot be stoped to overflow from the gap of door of existing labeled door, and labeled door back-fire relief on the whole or resistance to elevated temperatures do not hold by force yielding problem, there is provided a kind of and comprehensive there is fire-proof function, temperature distortion after not only can preventing the body from catching fire, effectively can also stop the steel heat insulation fireproof door that the intensity of a fire and flue gas overflow.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of steel heat insulation fireproof door, comprise doorframe, door leaf, be connected between doorframe and door leaf by hinge, door leaf is provided with handle and door lock, is provided with fire-proof door closer between doorframe and door leaf;
Described door leaf comprises skeleton and door skin, skeleton and door skin shaping by cold-rolling galvanization steel plate rolling, door skin is coated on outside skeleton and forms two-layer flat box body, composite fire door core material is poured into respectively in described two-layer flat box body, form the main body of two-layer door leaf, the main body of two-layer described door leaf forms a whole door leaf, and have gap between the main body of two-layer described door leaf, it is the door leaf of hollow form in the middle of being formed, the lower end of the door leaf of corresponding described hollow part is provided with air inlet, and upper end and the side of door leaf are provided with steam vent;
The crack between a door and its frame of the medial surface of described door leaf and the corresponding two fan door leafs of lateral surface, is respectively arranged with lid seam plate.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
The composite fire door core material (being anti-fire door core board after shaping) of filling in door leaf, is directly poured on door skin, makes the skeleton of door leaf, door skin become consolidation as a whole with anti-fire door core board; Double-deck anti-fire door core board makes to become hollow state in the middle of door leaf, and temperature can be allowed to cold and heat succeed each other in door circulation even if catch fire, make door leaf surface temperature isolation, outside is indeformable, can reach fire-proof and thermal-insulation effect significantly; In addition, between door leaf, install lid seam plate additional, spreading of the intensity of a fire or smog can to have been stoped better.
As preferably, the present invention further technical scheme is:
The watchcase of doorframe is shaping by cold-rolling galvanization steel plate rolling, casting cement mortar in watchcase; The cement mortar of doorframe inside can adopt nontoxic fire proofing material as main raw material(s), is heated even if catch fire, and doorframe is also not easy distortion, and surface temperature can not be too high.
The medial surface contact site of doorframe and door leaf fills and posts fire-proof expansion seal strip; The side, two ends of door leaf is provided with fire prevention notch, in fire prevention notch, is inlaid with fire-proof expansion seal strip; Spreading of the intensity of a fire and smog can be stoped better by fire-proof expansion seal strip.
Lid seam plate is made up of cold-rolling galvanization steel plate frame, the composite fire door core material be poured in cold-rolling galvanization steel plate frame, and lid seam plate is welded on door leaf, fills and post fire-proof expansion seal strip between lid seam plate and door leaf.Lid seam plate adopts the structure substantially identical with door leaf, and is directly welded on door skin, further enhancing door leaf intensity.
The steam vent that door leaf side is arranged is positioned at the position of installing hinge; Be more conducive to air circulation like this, protection hinge, strengthens the connection effect of door leaf and doorframe.
Hinge is hinge for fireproof; Described door lock is Fire-proof lock; The hinge made by fire proofing material, lock, its mass action can reach good fire-proof and thermal-insulation effect.
Fire-proof door closer is provided with between doorframe and door leaf; Fire-proof door closer can close door leaf effectively in time, blocks the intensity of a fire, smog and hot gas.
