Description
Technical field
The present invention relates to a kind of fire resistant doorsets, particularly a kind of steel heat insulation fireproof door.
Background technology
Fire resistant doorsets refer to meet within a certain period of time the door that fire stability, integrity and thermal insulation require.It is located between fire compartment, emergency staircase, vertical shaft etc. have the fire separation thing of certain fire resistance.In addition to the effect with common door, have more and stop fire spreading and the effect of flue gas diffusion, spreading of the intensity of a fire can be stoped within a certain period of time, it is ensured that evacuating personnel.
In existing fire resistant doorsets, the mode of packing material in its door leaf structure hollow door leaf of employing, packing material is usually rock wool, expanded perlite etc..Due to design structure problem, such fire resistant doorsets are difficult to stop the intensity of a fire and flue gas to overflow from the gap of door, so that fire resistant doorsets entirety fire resistance is the highest, the fire-resistance time is the longest.
Summary of the invention
The technical problem to be solved is the problem that the intensity of a fire and flue gas cannot be stoped to overflow from the gap of door for existing fire resistant doorsets, and fire resistant doorsets back-fire relief on the whole or the strongest problem of resistance to elevated temperatures, a kind of comprehensive door with fire-proof function is provided, temperature distortion after being not only possible to prevent door body to catch fire, it is also possible to effectively stop the intensity of a fire and flue gas to overflow.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is a kind of steel heat insulation fireproof door, is made up of doorframe and door leaf, is connected by hinge between doorframe and door leaf, door leaf is provided with handle and door lock, it is characterised in that the watchcase of described doorframe is made up of cold-rolling galvanization steel plate；Being poured by cement mortar inside of doorframe；Wherein cement mortar is prepared from according to the ratio of 1:2:5 by cement, sand and expanded perlite；Door leaf is made up of skeleton, door skin and composite fire-proof door panel, and wherein skeleton and door skin are made by cold-rolling galvanization steel plate, and composite fire-proof door panel is arranged in skeleton, and door skin cladding skeleton and composite fire-proof door panel i.e. make door leaf；On the doorframe contacted with door leaf, also dress has pasted fire prevention Expansion sealing sheet, and described hinge is fire prevention blind hinge, is also connected by fireproof door closer between doorframe and door leaf meanwhile；Described door lock is Fire-proof lock, and door leaf has also been installed Fireproof door mirror.
Described fire resistant doorsets are mother and sons' fire resistant doorsets or double open fire resistant doorsets, are mounted with lid seam plate between two door leafs；Described lid seam plate is made up of cold-rolling galvanization steel plate frame, inorganic fire-proof plate, fire-proof expansion seal strip and attaching plate；Inorganic fire-proof plate is arranged in cold-rolling galvanization steel plate frame, attaching plate shape perpendicular with cold-rolling galvanization steel plate is fixing to be connected, multiple interlaced elongated hole is dug on attaching plate, fire-proof expansion seal strip is arranged in the elongated hole of attaching plate, and attaching plate is fixedly mounted on during installation the side of a door leaf among two door leafs.
The invention has the beneficial effects as follows that the cement mortar within doorframe have employed expanded perlite as main raw material(s), being heated even if catching fire, it is also difficult to expand once again, being possible to prevent doorframe temperature distortion；The skeleton of door leaf, panel are made by galvanized steel plain sheet, and door core is made by fire proofing material, can reach fire-proof and thermal-insulation effect significantly；There is also mounted fire-proof door closer between doorframe and door leaf, door leaf can be closed the most in time, block the intensity of a fire and steam；Meanwhile, hinge, lock and peephole are made by fire proofing material, and its mass action can reach good fire-proof and thermal-insulation effect；Between door leaf, particularly install lid seam plate additional, also with fire-proof expansion seal strip on its attaching plate, can preferably stop spreading of the intensity of a fire or smog.
