Description
Technical field
The present invention relates to a kind of labeled door, particularly relate to a kind of fire prevention armoured door.
Background technology
Fire resistance steel door is primarily of doorframe and door leaf two parts composition, within 2008, the new edition standard GB12955-2008 of labeled door has drafted in the Ministry of Public Security, new standard specifies that filling out core material in labeled door must not use the fiber that can not degrade as labeled door core material, and therefore existing labeled door core material adopts pearlite slab mostly; Because the adhesion strength of pearlite slab self is poor, easy uncoupling after boning with steel plate, the factors such as the distortion of steel-sheet machining deformation, heat and collision deformation, not firm and solid with pearlite slab bonding all the time, directly affect the overall performance of labeled door.
Current labeled door shell is usually by the machine-shaping of individual layer steel plate, but the fire resistance steel door doorframe that individual layer steel plate is processed into is when breaking out of fire, and because the coefficient of thermal conductivity of steel is large, the temperature rise of carrying on the back fiery face is fast, does not reach the performance requirement of labeled door; The later intensity of individual layer steel plate machine-shaping is weak, and fireproof door frame is easily out of shape; Therefore the bonding of steel sheet and pearlite slab does not reach labeled door requirement, and if be subject to the collision of external force, also easily produce pearlite slab and panel uncoupling.
Summary of the invention
For prior art above shortcomings, the object of the invention is to how to solve existing labeled door flameproof effect poor, thermal insulation is poor, yielding, the problem effectively can not stop fire spreading, spreading along it, there is provided a kind of fire prevention armoured door, flameproof effect is better, and effectively can stop fire spreading, along its diffusion.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is such: a kind of fire prevention armoured door, comprise door leaf, door frame hinge and lockset, the side of door leaf by hinge and doorframe hinged, opposite side is connected with doorframe by lockset, it is characterized in that: described door leaf comprises by the stamping forming framework with panel, backboard and side plate of composite steel plate, in framework, be respectively equipped with fire prevention skeleton near both sides place, between two fire prevention skeletons, be filled with inorganic fire core material plate; Described fire prevention skeleton comprises several piece and is parallel to the refractory slab of panel and the composite board between refractory slab, and described refractory slab and composite board are alternately distributed, and is bonded together by resistant to elevated temperatures glue;
The biside plate of framework is respectively equipped with the alloy button limit that a section is L-type, and side and the side plate on described alloy button limit bond together, and opposite side is concordant with backboard, wherein, are bent to form a buckling groove near the alloy button limit of lockset side towards panel side;
Be pasted with one deck fireproof decoration plate respectively at the panel of door leaf framework and back plate surface, and the alloy button limit of framework both sides is covered by this fireproof decoration plate;
Described doorframe is that two-stage is step-like near the side of door leaf both sides, and when door leaf cuts out, decoration panel is positioned at the one-level step of doorframe, and alloy button limit is positioned at the two stage steps of doorframe; In the side of doorframe near lockset, corresponding buckling groove is also provided with a plate, and when door leaf cuts out, this plate inserts in this buckling groove.
Further, between doorframe and decoration panel, be provided with fire prevention expansion adhesive tape, described fire prevention expansion adhesive tape and doorframe bond together.
Further, described composite steel plate comprises two block plates, and two block plates are bonded together by high temperature resistant adhesive.
Further, between door leaf upper end and doorframe upper end, a fire-proof door closer is also provided with.
Compared with prior art, tool of the present invention has the following advantages:
1, door leaf adopts composite steel plate, fire prevention skeleton and inorganic fire core material to harden the structure of closing, and can meet the fire-proof and thermal-insulation requirement of labeled door, increase the bulk strength of labeled door and anti-impact force, during breaking out of fire, entirety is not yielding; And there is good soundproof effect, good heat insulation effect.
2, the framework of door leaf adopts two-layer compound steel plate, and centre meets cementing agent for high strength, makes coefficient of thermal conductivity low, can reach fire-proof and thermal-insulation requirement, and the intensity of composite metal plate is large, and fireproof door frame is not yielding; Not only considerably increase the bulk strength of door, crashproof pick-proof, protecting against shock, the effect of good insulation, sound insulation can also be played.
3, in door leaf framework, fire prevention skeleton is set near both sides, heat-blocking action can be played better, and ensure door leaf, especially the stability of door leaf both sides, avoid causing fire spreading and flue gas diffusion because of the distortion of door leaf both sides.
The biside plate of 4, door leaf framework arranges alloy button limit, because alloy buckle high temperature strength is higher, therefore stability is better, thus flameproof effect can be improved better, and during door leaf closedown, door leaf and doorframe form two-stage and overlap, thus flameproof effect can be made better, and have better anti-theft effect concurrently.
