The cavity-type steel fireproof door is characterized in that the door leaf frame is provided with a hollow cavity; fireproof plate layers are arranged on the front and rear surfaces of the door leaf frame respectively; and steel door leaf panel layers are arranged on the outer faces of the fireproof plate layers. The cavity-type steel fireproof door has the advantages that compared with the prior designs and processing schemes, the fireproof door is in the structure of the two-side fireproof plate layer and steel door leaf panel layer, the structure allows the cavity to form in the door leaf frame, filling heat-insulation and fireproof inorganic materials (inorganic foaming pearl core) is omitted, corrosion of the steel plates is avoided, and security risks are eliminated. The weight of each set of the fireproof door is reduced by 25% to 35%; the process is simpler, labor hours are less, labor cost is almost reduced by 30%; and the strength of the fireproof door is increased by 10% to 15%.
Description
Technical field
The utility model belongs to heat-insulating fireproof door, relates in particular to a kind of cavity type fire resistance steel door.
Background technology
Fire-proof wooden door is widely used in the construction work, it is provided in a side of between fire compartmentation, between escape stair, fire separation thing with certain refractoriness such as vertical vertical shaft, can satisfy fire stability, integrality and thermal insulation requirement within a certain period of time.Labeled door has more the effect that stops fire spreading and flue gas diffusion except the effect with common door, can stop spreading of the intensity of a fire within a certain period of time, guarantees evacuating personnel.The fire-proof wooden door structure is to make doorframe, door leaf skeleton, door skin etc. with timber or timber-work to make stuffed heat insulated, fire proofing material in the panel surface sprayed fire proofing coating, skeleton.How to play heat insulation, anti-fire action with the expanded pearlite rock beam at present.The expanded pearlite rock beam can play the anti-fire action of expection, but it has low, the shortcomings such as heavy, the difficult installation of labeled door quality that the glue consumption is big, cost is high, be processed into of preventing fires of working (machining) efficiency.Application number: 201120273751.2 disclose a kind of steel heat-insulating fireproof door that stops fire spread speed.This steel heat-insulating fireproof door comprises doorframe and is articulated at least one interior door leaf of doorframe, it is characterized in that: described door leaf comprises the door leaf frame and is fixed in two block plates of described door leaf frame both sides, described steel plate constitutes the panel of door leaf, is filled with the foaming perlite flaggy in described steel plate and the door leaf frame.The utility model has the advantages that: adopt material nontoxic to human body, fire insulation 〉=1.50 hour fire integrity 〉=1.50 hours, on performance, can guarantee the fire spreading that stops of longer time, can be widely used in the place that commercial center, office premises, hotel, station, factory, highrise building etc. have fire protection requirement.Application number: 201120502949.3 disclose a kind of steel heat-insulating fireproof door, comprise: steel doorframe, door leaf, Fire-proof lock, fire prevention door closer, fire prevention hinge, door leaf is fixed on the steel doorframe, coincide with the steel doorframe size, Fire-proof lock, fire prevention door closer are separately fixed on door leaf and the steel doorframe, door leaf is set up jointly into by wooden frame inorganic foaming perlite central layer, lining steel plate, two-sided PLASTIC LAMINATED and panel glue, and doorframe rabbet place and/or double door fan bump sealing anti-plume is set.
The architectural design personnel preferably use fire resistance steel door usually in design, it selects for use ratio to account for 90%, and fire-proof wooden door is generally seldom selected for use owing to the cost height.But the foaming perlite flaggy of filling in the fire resistance steel door belongs to acid, and Fire-proof steel plate is had stronger corrosivity.Through after a while, steel plate then is corroded, and has not had anti-fire action, has very large potential safety hazard.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of cavity type fire resistance steel door is provided, no longer stuffed heat insulated fireproofing inorganic material in the door leaf skeleton, form cavity, the integral door body weight is alleviated, avoided the corrosion of steel plate, eliminated potential safety hazard.
The utility model for achieving the above object, by the following technical solutions: a kind of cavity type fire resistance steel door, comprise the door leaf that door leaf skeleton and door skin constitute, it is characterized in that: described door leaf skeleton is made as the hollow type inner chamber, the front and rear surfaces of described door leaf skeleton is respectively equipped with the fire prevention flaggy, and described fire prevention flaggy external surface is provided with steel door skin layer.
Uniform some fire prevention or fire-retardant support cross band on the described door leaf skeleton, described support cross band is provided with several air-vents, and the crossbeam of described door leaf skeleton bottom is provided with several air-vents.
Described door leaf is fixed on the steel doorframe, and door leaf and steel doorframe size are coincide, and pass through the hinged at least door leaf of fire prevention hinge in the described doorframe.
Fire prevention door closer and Fire-proof lock are fixedly arranged on described door leaf and the steel doorframe.
Beneficial effect: compare with processing scheme with original design, adopt two sides fire prevention flaggy and steel door skin layer structure, can make and form cavity in the door leaf skeleton, no longer stuffed heat insulated and fireproof inorganic material (inorganic foaming perlite core), avoid the corrosion of steel plate, eliminated potential safety hazard.The every door frame weight saving about 25%～35% of labeled door; Technology is comparatively simple, and labor hour is few, reduces the cost of labor about 30% approximately; Improve the intensity about 10%～15% of labeled door; Because technology is simpler, employee's operation easier reduces, and more can guarantee the quality of product; Because labeled door is in light weight, be more convenient for for construction and installation; Save fire prevention glue and be about about 30%, reduced the pollution to environment.
