Description
Technical field
The utility model relates to a kind of labeled door, particularly relates to a kind of steel composite fire door.
Background technology
Current fire resistance steel door is primarily of doorframe and door leaf two parts composition, traditional fire resistance steel door adopts whole-steel manufacture of materials to make, fire insulation performance for fire resistance steel door is the test that fire resistance steel door is huge, and existing fire resistance steel door core material is serious for the corrosion failure of steel plate, a large amount of fire resistance steel doors is installed and used at the scene and was just created corrosion less than 2 years.Meanwhile, the coefficient of thermal conductivity of traditional fire resistance steel door steel plate is high, when breaking out of fire, also easily causes door leaf unexposed surface temperature high, easily causes door leaf to be out of shape, thus do not reach labeled door performance requirement.
Utility model content
For prior art above shortcomings, it is poor, yielding that the purpose of this utility model is how to solve existing fire resistance steel door thermal insulation, the problem of fireproof performance difference, provides a kind of steel composite fire door, can improve heat-proof quality, avoid distortion, thus improve fireproof performance.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is such: a kind of steel composite fire door, comprise door leaf, doorframe and hinge, the side of described door leaf by hinge and doorframe hinged, it is characterized in that: described door leaf comprises by panel, the framework that backboard and side plate are formed, fire prevention skeleton is respectively equipped with near biside plate place in framework, 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 bonded together by resistant to elevated temperatures glue, at panel, inorganic fire core material plate is filled with in the cavity that backboard and two fire prevention skeletons are formed,
The section of described doorframe is stepped ramp type, and when door leaf cuts out, the side plate of door leaf contacts with the concave surface of doorframe, makes in door leaf embed wholly doorframe; The face contacted with door leaf at doorframe is provided with groove, offers insulation hole, in groove, be provided with fire seal in the bottom surface of this groove, and this fire seal protrudes from groove.
Further, between the panel and doorframe of door leaf, be provided with expansion adhesive tape of preventing fires, this fire prevention expansion adhesive tape and doorframe bond together.
Further, the framework of described door leaf and doorframe are by clad metal sheet punch forming, and described clad metal sheet comprises two pieces of metal sheets and between two pieces of metal sheets and by bonding agent bonding for two pieces of metal sheets.
Compared with prior art, the utility model tool has the following advantages:
1, adopt (compound) prevent fires bulk strength of steel composite fire door of carcassing large, door leaf can effectively play refractory heat-insulating effect, in fire resistance test, fireproof door frame door leaf is not yielding, improve the fireproof performance of labeled door and the application life of labeled door, can also play good function of heat insulation, heat-proof quality is far away higher than the steel fire-proof wooden door of routine, and fire insulation performance is fully ensured.
2, adopt in door leaf framework inorganic fireproof material to fill, saved a large amount of primary timber, and the toxic waste liquid discharge of deduction and exemption fire-retarding of wood process and fire-retardant process and fire-retardant rear timber stoving process, save a large amount of fuel, protection of the environment, protect forest.
3, doorframe adopt steel door frame, door leaf adopt composite material make door leaf, effectively meet Fireproof door structure fastness and; The labeled door of this structure fabrication has preferably fire insulation performance, has preferably Anti-knocking performance; Labeled door performance is more reliable and more stable, meets the technical quality safety requirements of labeled door completely, and this product structure is simple simultaneously, is convenient to large-scale production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 local along A-A to sectional view.
In figure: 1-door leaf, 11-framework, 12-fire prevention skeleton, 13-fire prevention core material plate, 2-doorframe, 3-hinge, 4-insulation hole, 5-fire seal, 6-fire prevention expansion adhesive tape, 7-fire-proof door closer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1, Fig. 2, a kind of steel composite fire door, comprises door leaf 1, doorframe 2 and hinge 3, and the side of described door leaf 1 is hinged by hinge 3 and doorframe 2, and described hinge 3 adopts hinge for fireproof 3; During concrete enforcement, between doorframe 2 upper end and door leaf 1 upper end, be also provided with a fire-proof door closer 7, can in time door leaf 1 cut out by this fire-proof door closer 7, avoid fire spreading, flue gas to spread.Described door leaf 1 comprises the framework 11 formed by panel, backboard and side plate, fire prevention skeleton 12 is respectively equipped with near biside plate place in framework 11, described fire prevention skeleton 12 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.Inorganic fire core material plate 13 is filled with in the cavity that panel, backboard and two fire prevention skeletons 12 are formed; Described inorganic fire core material plate 13 adopts existing product, the fire prevention core material plate 13 disclosed in the patent (patent No.: ZL 201110229683.4) that the applicant has applied for, heat insulation, fireproof performance is better.
The section of described doorframe 2 is stepped ramp type, and when door leaf 1 cuts out, the side plate of door leaf 1 contacts with the concave surface of doorframe 2, makes in door leaf 1 embed wholly doorframe 2.The face contacted with door leaf 1 at doorframe 2 is provided with groove, offers insulation hole 4 in the bottom surface of this groove, makes effect of heat insulation better.Fire seal 5 is provided with in groove, and this fire seal 5 protrudes from groove, when door leaf 1 cuts out, fire seal 5 compresses by door leaf 1 side plate, thus closed in the gap between door leaf 1 and doorframe 2 by fire seal 5, thus improve fire prevention, anti-smoke performance.Between the panel and doorframe 2 of door leaf 1, be provided with expansion adhesive tape 6 of preventing fires, this fire prevention expansion adhesive tape 6 bonds together with doorframe 2, prevents fire spreading, flue gas from spreading further, thus plays better flameproof effect.
