Description
Technical field
The utility model is related to a kind of fire resistant doorsets, more particularly to a kind of steel fire-proof wooden door.
Background technology
Practical various fire resistant doorsets are broadly divided into two kinds at present, and one is steel-made fire-retardant doors, its fire protecting performance is good, but cost
Height, weight weight, heat preservation, sound insulation value are poor, and steel belong to non-renewable resources, and another kind is wooden fire resistant doorsets, it is with timber
For skeleton, the various flame-proof heat-resistant material of central filler, its low cost is light-weight, and is regenerated resources, but its bonding strength is low,
Whole fire insulation, fire integrity are not so good as the former.
Notification number is that the utility model patent of CN2188070U discloses a kind of fireproof composite door for ship, including steel door
The two sides of frame and door leaf, the door leaf is fire-retardant three-ply board, and central filler has ceramic wool.Since the door leaf two sides of the fire resistant doorsets is
Fire-retardant three-ply board, central filler have ceramic wool.
This steel wooden fireproof door structure is simple, and when fire occurs, door-plate is burnt can deform after a certain period of time, will
Lead to the scarce capacity of fire-proof door curtain itself filtering dense smoke, and the leakproofness between crack between a door and its frame is limited, the dense smoke pole of scene of fire has
May pass through fire resistant doorsets, anthracemia occur so as to cause the people hidden on the inside of fire-proof door curtain, thus the program there are still
Larger security risk.
Utility model content
The purpose of this utility model is to provide a kind of steel fire-proof wooden door, its advantage is that improve steel fire-proof wooden door every cigarette
Effect, to which safety be greatly improved.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of wooden fire prevention of steel

The fire-retardant baffle 37 of 3 unlatching, 2 top of door leaf can prevent flare from being contacted immediately with fuse link 31, after evacuating personnel, then
Fire-retardant baffle 37 is pulled out from sliding slot 39 manually, turns off door leaf 2, fuse link 31 can just work at this time, play the control intensity of a fire
Effect.
As shown in Figure 2, Figure 4 shows, fire-retardant baffle 37 is made of hard polyaminoester plastics, since hard polyaminoester plastics are anti-
Fiery, fire-retardant and high temperature resistant belongs to fire retardant self-extinguishing, and it does not also generate pernicious gas, therefore its energy at high temperature
Effectively fuse link 31 is avoided to be damaged because of high temperature or the intensity of a fire, to which the unlatching of manual control latch gear 3 be effectively ensured.
As shown in Figure 3, Figure 4, latch gear 3 is opened to improve personnel（With reference to figure 2）Convenience, fire-retardant baffle 37 is close
The side that door leaf 2 is open is equipped with internal buckle handle 38.It is embedded in door leaf 2 when fire-retardant baffle 37 is flat, the design of internal buckle handle 38 not shadow
Ring the closing of door leaf 2.It when needing to start latch gear 3 when fire, needs to remove on fire-retardant baffle 37, the internal buckle of internal buckle setting
Handle 38 smoothly pulls out fire-retardant baffle 37 convenient for staff.
As shown in figure 5, for ease of personnel escape, fire resistant doorsets are passed through, 1 side of steel door frame is provided with spray equipment 4,
Spray equipment 4 includes several water jets 42 from top to bottom set gradually along steel door frame 1, and each water jet 42 is towards door leaf 2.
1 side of steel door frame connects the water tank 41 of the water supply of promising spray equipment 4, and water tank 41 is suspended on the wall side where door leaf 2
On wall, water tank 41 is connected to water jet 42 by hose, and water tank 41 is equipped with the smoke sensor device 411 for monitoring fire behavior.
Smoke sensor device 411 can perceive fire behavior, open spray equipment 4 if necessary automatically, in fire to door by locating spraying water curtain,
Since water jet 42 is tilted towards door leaf 2, when fire occurs, spray equipment 4 will be in water tank 41 by water jet 42
Water is sprayed onto on door leaf 2, reduces 2 burned degree of door leaf, the liquid of the sprinkling of spray equipment 4, which can also dissolve a part, poison gas
Body reduces the amount of personnel's incoming call toxic gas so that fire resistant doorsets can control fire behavior sprawling to greatest extent, and personnel pass through door leaf
If surrounding has flare when 2, it also can reduce the intensity of a fire by spray equipment 4, pass through convenient for personnel.
As shown in fig. 6, thermal insulation layer 21, flame retardant bed 22 and filter layer are respectively equipped in the steel layer 24 of door leaf 2 from inside to outside
23, the inner wall of steel layer 24 is equipped with the first card slot 241, the second card slot for being embedded thermal insulation layer 21, flame retardant bed 22, filter layer 23
242 and third card slot 243.Each layer is entrenched in inside, structure by the first card slot 241, the second card slot 242, third card slot 243
Stablize and protects 2 internal structure of door leaf.
Thermal insulation layer 21 is made of the compound curtain plate for completely cutting off the intensity of a fire.Heat-insulated compound curtain plate not only completely cuts off heat, reduces
Excessive deformation due to heat is excessively high of door leaf 2, while reducing the transmission of heat, fire-retardant compound curtain plate can also effectively completely cut off fire
Gesture.Flame retardant bed 22 is made of refractory fiber cloth, and the refractory fiber cloth is made of ceramic fibre.Ceramic fibre is a kind of fibre
Shape lightweight refracrory is tieed up, has many advantages, such as that light-weight, high temperature resistant, thermal stability are good, thermal conductivity is low and specific heat is small, further carries
The back-fire relief and heat insulation of high fire resistant doorsets.Filter layer 23 is made of activated carbon, and the filter layer 23 is externally provided with gelatinization cotton 231,
Gelatinization cotton 231 is coated and fixed by way of braiding outside filter layer 23.
Gelatinization cotton 231 outside activated carbon can play the role of dense smoke tentatively to filter, can basic filtering fall dense smoke
The relatively large particle dust of middle grain size and suspended matter；Activated carbon is a kind of porous carbon materials, and adsorption capacity is strong, in filter layer 23
Activated carbon is set, and activated carbon can further adsorb the flue dust in air, to further decrease dense smoke across fire resisting shutter
Risk.
By thermal insulation layer 21, flame retardant bed 22, the effect of multilayer isolation is played to the intensity of a fire of scene of fire, greatly improves steel
The Fire resistances of fire-proof wooden door, and the dense smoke of scene of fire is effectively filtered and adsorbs, the risk that dense smoke passes through fire resistant doorsets is reduced,
To improve fire resistant doorsets it is whole every cigarette effect, improve safety.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
