Description
Technical field
The utility model relates to fire protection fields, more specifically, it relates to a kind of fire resistance steel door.
Background technique
Fire is one of the common disaster for threatening human life's safety.Fire resistant doorsets refer to the door with fire resistance, are sending out
Fire is fled from when calamity of lighting a fire for people to gain time, prevent fire diffusion, delay fire spread and fire resisting certain time.Therefore,
Fire resistant doorsets play a crucial role in the case of fire, fire resistant doorsets be broadly applied private residence, ship, building, chemical industry,
Many fields such as mechanical engineering.Now, common fire resistant doorsets are all metallic door, using the high feature of melting point metal, in a fire
The nonflammable thawing of metal, can effectively prevent fire spread.
But although metallic door is not easy to be burned out, but have good thermal conductivity, when fire occurs, passes through metallic door
The high temperature of conduction can equally light surrounding article after accumulating a period of time.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of fire resistance steel door, pass through by
Door-plate hierarchical design will not easily reach excessively high temperature so that the fire resistance of door-plate is more preferable.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of fire resistance steel door,
The two panels door-plate that doorframe is rotationally connected with including doorframe, by hinge, the keeper for connecting two door-plates, be connected to door-plate and doorframe it
Between door closer, the hinge between connection door-plate and doorframe, the door-plate includes metal shell, is accommodated in the intracorporal nothing of metal-back
Machine rock stratum, wherein being equipped with liquid water in inorganic rock stratum；The door-plate through-thickness is equipped with through-hole, and the through-hole both ends are equipped with close
Blocking.
When fire occurs, door closer closes door-plate, and subsequent flame slowly heats door-plate, at this time the liquid in door-plate
Water boiling breaks through sealing-plug, then sheds, and can not only reduce the heat of fire resistant doorsets, while can also rise to the flame of surrounding
To certain inhibiting effect.
The utility model is further arranged to: the through-hole is set at the top of door-plate.
By the way that through-hole to be set to the top of door-plate, enables and directly shed from top when water evaporation.
The utility model is further arranged to: anti-slip ring is equipped between the sealing-plug and metal shell.
By the design of anti-slip ring, so that sealing-plug will not be skidded off easily out of through-hole.
The utility model is further arranged to: the sealing-plug is made using rubber.
By the way that sealing-plug to be made using rubber, sealing-plug is enabled to have certain elasticity, it not only can stronger company
It is connected in through-hole, and but also steam is easier to eject sealing-plug.
The utility model is further arranged to: sealing is equipped at the two door-plates abutting, the sealing includes opening up
In the groove of door-plate, it is opened in the raised line of another door-plate, raised line is matched with groove.
By the cooperation of raised line and groove so that the connection of two door-plates is stronger, the flue dust for generating flame be not easy from
It sheds between two door-plates.
The utility model is further arranged to: the hinge is set to the side where door closer.
By the design of hinge, so that the side where door-plate towards door closer and keeper is opened, so that when back
When the external world from door knob catches fire, flame can not burn fragile hinge, further promote the flameproof effect of fire resistant doorsets；
And when fire occurs towards keeper side, captive can open keeper and escape, and the effect of fire resistant doorsets is only
It is limited to the isolation intensity of a fire rather than protects the captive besieged, the fire protection requirement of fire resistant doorsets is suitably reduced.
The utility model is further arranged to: fire protection flame retarding item is equipped between the door-plate and doorframe.
By the design of fire protection flame retarding item so that flame and flue dust be not easy the gap between door-plate and doorframe into
Enter.
The utility model is further arranged to: the keeper is equipped with door handle, and the door handle is equipped with friction striped.
By the design of rub striped and handle, so that keeper is easier to open.
In conclusion the utility model has the following beneficial effects:
First, by by door-plate hierarchical design, so that the fire resistance of door-plate is more preferable, excessively high temperature will not be easily reached；
Second, pass through the design of raised line and groove, so that the better tightness of fire resistant doorsets, to improve the fire prevention of fire resistant doorsets
Performance.
