Description

People's air defense fire resistant doorsets
Technical field
The utility model is related to a kind of people's air defense fire resistant doorsets, belong to defense equipment field.
Background technology
Currently, fire resistant doorsets refer to the door that disclosure satisfy that fire resistance, integrality and thermal insulation within a certain period of time and require, it is to set Set the fire protection separators that there is certain fire resistance in fire protection interval, emergency staircase, vertical shaft etc..Such as:It is attached to height The canyon (steel cylinder room, foam station etc.) of fixed equipments for fire protection in floor civil buildings, the partition wall of ventilation, air handling unit room etc. Door should use first class fire resistant doorsets;The door on basement room partition wall that frequent someone stops or combustible is more, should use first class Fire resistant doorsets;Because subject to conditions, it is necessary in skyscraper arrange fuel oil, combustion gas boiler, combustible oil-filled electric transformer, Filled with can fuel oil high-voltage capacitor and switch etc., the door on andron partition wall should all use first class fire resistant doorsets.Also design There is a palpus fireproof partition door of particular/special requirement, such as fire fighting monitoring command centre, archives material room, valuables warehouse divide family Door usually selects first class or second class fire resistant doorsets.The partition door in high-rise senior house building, frequently with fireproof and theftproof door.Fire resistant doorsets are Important component in fire-fighting equipment, is the important ring in society's fire prevention, and fire resistant doorsets should install fireproof door closer or set The door closer-holder for allowing normally opened fire resistant doorsets that door leaf can be automatically closed when fire occurs is set (except privileged sites use, such as piping shaft Door etc.).
Inventor has found that traditional fire resistant doorsets at least have the disadvantage that in use under study for action:Fire resistant doorsets exist Easily occur the deformation such as warpage, bending in the case of temperature is higher, causing to prevent fires between door main body and fireproof door frame gap occurs, fire Seedling or dense smoke are easily scurried out from gap, thereby reduce security protection performance, fireproof effect is poor, accident easily occurs.
It is therefore desirable to design a kind of people's air defense fire resistant doorsets, to overcome the above problem.
Utility model content
The purpose of the utility model is to overcome the defect of the prior art, provide it is a kind of it is simple in structure, fire protecting performance is good, The preferable people's air defense fire resistant doorsets of flameproof effect.
The utility model is realized in this way:
The utility model provides a kind of people's air defense fire resistant doorsets, includes lamina rara externa, the first magnesium oxide plate, the successively from outside to inside One steel plate, the second magnesium oxide plate, intermediate plate, third magnesium oxide plate, the second steel plate, the 4th magnesium oxide plate and inner plating;
The people's air defense fire resistant doorsets further include a framework, second magnesium oxide plate, the intermediate plate and the third Magnesium oxide plate may be contained in the framework, and the framework is set between first steel plate and second steel plate, described The length and width of framework is identical as the length and width of the first steel plate;
Wherein, the intermediate plate is fiberboard, and first steel plate is identical with the structure of second steel plate.
Further, the lamina rara externa is identical with the structure of the inner plating.
Further, the lamina rara externa and the inner plating are melamine board.
Further, the two sides of first steel plate and second steel plate are equipped with zinc coat.
Further, first magnesium oxide plate is identical as the structure of the 4th magnesium oxide plate.
Further, second magnesium oxide plate is identical as the structure of third magnesium oxide plate.
The utility model has the advantages that:
The people's air defense sets gradually magnesium oxide plate layer, steel plate layer, magnesium oxide plate layer with fire resistant doorsets in the both sides of middle layer, can Effectively to increase flameproof effect, and framework is set between first steel plate and second steel plate, it can be further Enhance the integral strength of the people's air defense fire resistant doorsets, to improve fire protecting performance, structure is also relatively simple.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the sectional view for the people's air defense fire resistant doorsets that the utility model embodiment provides.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are in the premise for not making creative work Lower obtained all other embodiment, shall fall within the protection scope of the present invention.
Such as Fig. 1, the utility model embodiment provides a kind of people's air defense fire resistant doorsets, includes lamina rara externa 1, the successively from outside to inside One magnesium oxide plate 2, the first steel plate 3, the second magnesium oxide plate 4, intermediate plate 5, third magnesium oxide plate 6, the oxidation of the second steel plate the 7, the 4th Magnesium plate 8 and inner plating 9.It is bonded by strength plastic cement between adjacent two-ply, when necessary, can also use fixing glue etc. To fix.
