Abstract
The invention discloses a fire resistance steel door. The fire resistance steel door comprises a door leaf, a door frame and hinges, wherein the door leaf comprises a frame body; the two sides of the fame body are each provided with a protrusion; the positions, near two side boards, inside the frame body, are provided with fire resistance frames; an inorganic fire resistance core plate is filled between the two fire resistance frames; one side, in contact with the two sides of the door leaf, of the door frame, is of a two-step shape; when the door leaf is closed, the door leaf is integrally embedded into the door frame, wherein the frame body is located in a fist step of the door frame and each protrusion is located in a corresponding second step of the door frame. According to the fire resistance steel door, thermal insulation and heat preservation are achieved, and the fire resistance effect is good.
Description
Technical field
The present invention relates to a kind of labeled door, particularly relate to a kind of fire resistance steel 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 current labeled door core material adopts pearlite slab mostly; But 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.
And the fire resistance steel door doorframe that individual layer steel plate is processed into is when breaking out of fire, 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; The door leaf of fire resistance steel door adds pearlite slab bonding by upper and lower two layers of thin steel plate and forms, because steel-sheet plasticity is stronger, very easily be out of shape in process or after preheating, therefore the bonding of steel sheet and pearlite slab does not reach labeled door requirement, if and be subject to the collision of external force, also easily produce pearlite slab and panel uncoupling, do not reach fire protection requirement.
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, heat insulating ability are poor, the problem effectively can not stop fire spreading, spreading along it, a kind of fire resistance steel door is provided, effectively can play effect that is heat insulation, insulation, flameproof effect is better.
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 resistance steel door, comprises door leaf, doorframe and hinge, the side of door leaf by hinge and doorframe hinged; It is characterized in that: described door leaf comprises by composite steel plate punch forming and has the framework of panel, backboard and biside plate, the both sides of described framework are respectively equipped with a projection, described projection is concordant with the backboard of framework; Fire prevention skeleton is provided with near biside plate place in framework, inorganic fire core material plate is filled with between two fire prevention skeletons, described fire prevention skeleton comprises several piece and is parallel to the refractory slab of panel and the composite board between refractory slab, described refractory slab and composite board are alternately distributed, and are bonded together by resistant to elevated temperatures glue;
The side that described doorframe contacts with door leaf two sides is that two-stage is step-like, and when door leaf cuts out, in door leaf embed wholly doorframe, wherein, framework is positioned at the one-level step of doorframe, and projection is positioned at the two stage steps of doorframe.
Further, between doorframe and framework panel, be also provided with expansion adhesive tape of preventing fires, described fire prevention expansion adhesive tape and doorframe bond together.
Further, described composite steel plate comprises two block plates, is provided with high temperature resistant adhesive between two block plates, and two block plates are bonded together by this high temperature resistant adhesive.
Further, between door leaf upper end and doorframe upper end, a fire-proof door closer is provided with.
Compared with prior art, tool of the present invention has the following advantages:
1, structure is simple, and 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 bulk strength and the anti-impact force of labeled door, during breaking out of fire, entirety is not yielding; And there is good soundproof effect, good heat insulation effect.
2, when door leaf cuts out, door leaf and doorframe form two-stage and overlap, thus flameproof effect can be made better, and have better anti-theft effect concurrently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-framework, 2-fire prevention skeleton, 3-inorganic fire core material plate, 4-protruding, 5-doorframe, 6-fire prevention expansion adhesive tape.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment: see Fig. 1, a kind of fire resistance steel door, comprises door leaf, doorframe 5 and hinge, the side of door leaf by hinge and doorframe 5 hinged.Between doorframe 5 and framework 1 panel, be also provided with expansion adhesive tape 6 of preventing fires, described fire prevention expansion adhesive tape 6 bonds together with doorframe 5; Like this, when fire occurs, door leaf can cut out by fire-proof door closer in time, thus effectively prevents fire spreading and flue gas diffusion.
Described door leaf comprises by composite steel plate punch forming and has the framework 1 of panel, backboard and biside plate, and described composite steel plate comprises two block plates, is provided with high temperature resistant adhesive between two block plates, and two block plates are bonded together by this high temperature resistant adhesive; Effect of heat insulation is better, and not only fireproof performance is good, and is more conducive to insulation.The both sides of described framework 1 are respectively equipped with a projection 4, described protruding 4 concordant with the backboard of framework 1; During concrete enforcement, this projection 4 is bent to form by composite steel plate, makes resistance to overturning better, crashproof, high temperature strength is higher.The side that described doorframe 5 contacts with door leaf two sides is that two-stage is step-like, when door leaf cuts out, in door leaf embed wholly doorframe 5, wherein, the panel of framework 1() be positioned at the one-level step of doorframe 5, protruding 4 two stage steps being positioned at doorframe 5.
Fire prevention skeleton 2 is provided with near biside plate place in framework 1, inorganic fire core material plate 3 is filled with between two fire prevention skeletons 2, described fire prevention skeleton 2 comprises several piece and is parallel to the refractory slab of panel and the composite board between refractory slab, described refractory slab and composite board are alternately distributed, and are bonded together by resistant to elevated temperatures glue.Described inorganic fire core material plate 3 is ripe prior art, the fire prevention core material plate disclosed in the patent that the applicant can be adopted to have applied for (patent No.: ZL 201110229683.4), heat insulation, fireproof performance is better.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
