Abstract
The utility model relates to a hollow wood insulated fireproof door which comprises a door leaf framework and door leaf panels. The fireproof door is characterized in that fireproof door leaf panels are adhered on two surfaces of the door leaf framework, and the door leaf framework adopts a hollow cavity. The door has the benefits that compared with the traditional design and processing scheme, the door has the advantages that the weight of each door is reduced by about 25 to 35 percent; the technology is simpler, the labor hour is less, and the labor cost is reduced by about 30 percent; the strength of the fireproof door is improved by about 10 to 15 percent; as the technology is simpler, the operation difficulty for workers is reduced, and the product quality can be further guaranteed; as the weight of the fireproof door is reduced, construction and installation are more convenient; and the amount of fireproof adhesive is reduced by about 30 percent.
Description
Technical field
The utility model belongs to heat-insulating fireproof door, relates in particular to a kind of empty stomach wooden heat-insulating fireproof 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 that 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 at present with the expanded pearlite rock beam.With the expanded pearlite rock beam is the anti-fire action that can play 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.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of empty stomach wooden heat-insulating fireproof door, no longer stuffed heat insulated, fire proofing material in the door leaf skeleton, form cavity, the integral door body weight is alleviated, and processing technology is simplified, and fire prevention glue consumption reduces, the door body structure strength-enhanced, easy for installation.
The utility model for achieving the above object, by the following technical solutions: a kind of empty stomach wooden heat-insulating fireproof door, comprise door leaf skeleton and door skin, it is characterized in that: the fire-proof door leaf panel is pasted on two surfaces of described door leaf skeleton, and door leaf skeleton is made as the hollow type inner chamber.
Uniform some fire prevention of the hollow type inner chamber of described door leaf skeleton or fire-retardant support cross band, described support cross band is provided with several air-vents, and described door leaf base cross members is provided with several air-vents.
Beneficial effect: compare with processing scheme with original design, mainly contain the advantage of the following aspects: no longer stuffed heat insulated, fire proofing material in the door leaf skeleton form cavity.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 like this, more can guarantee the quality of product; Because labeled door is in light weight, be more convenient for for construction and installation; Having saved fire prevention glue is about about 30%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of empty stomach wooden heat-insulating fireproof door comprises door leaf skeleton 1 and door skin 2, and the fire-proof door leaf panel is pasted on two surfaces of described door leaf skeleton, and door leaf skeleton is made as hollow type inner chamber 3.Uniform some fire prevention of described door leaf skeleton or fire-retardant support cross band 4, described support cross band is provided with several air-vents 5, and described door leaf base cross members 6 is provided with several air-vents 5.
Wooden frame structure before labeled door continues to adopt, the side towards the fire of door all adopts special PLASTIC LAMINATED to paste with the fiery face of the back of the body, suitably dosing fire prevention lath or fire retarding wood according to door leaf physical dimension size does and supports and bored air-vent, make and form several little spaces between the two-layer PLASTIC LAMINATED naturally, play heat-blocking action, simultaneously the door leaf bottom has been bored air-vent and is made air between the labeled door under the situation of heating, take away corresponding heat, prevent that the unexposed surface temperature rising is too fast and can not reach heat insulation effect.
Material object designs, has manufactured second class wooden labeled door on an empty stomach, entrusts national fixed fire extinguishing system and fire retarding component quality supervision and test center to carry out fire duration test,
Application grade: A1.50(first class);
Pilot project: fire resistance;
Experimental basis: fire insulation 〉=1.50h, fire integrity 〉=1.50h;
Measured result: final fire resistance period is 73 minutes, is lost integrity; Carry on the back 95.7 ℃ of the highest average temperature risings of fiery face, 183.0 ℃ of the highest single-point (except that doorframe) temperature rises, the highest single-point temperature rise is 88.4 ℃ on the doorframe, easily loses thermal insulation.Fire insulation equals 1.22h, and fire integrity is greater than 1.22h.60 minutes the fire endurance that has surpassed national Specification proves that new design and processing scheme satisfy the requirement of national standard fire resistance fully.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. an empty stomach wooden heat-insulating fireproof door comprises door leaf skeleton and door skin, it is characterized in that: the fire-proof door leaf panels are pasted on two surfaces of described door leaf skeleton, and door leaf skeleton is made as the hollow type inner chamber.
2. according to the described empty stomach wooden heat-insulating fireproof door of claim 1, it is characterized in that: uniform some fire prevention of the hollow type inner chamber of described door leaf skeleton or fire-retardant support cross band, described support cross band is provided with several air-vents, and described door leaf base cross members is provided with several air-vents.
