Abstract
The utility model relates to a fire-proof smoke-proof steel door. The utility model comprises a doorframe, a door leaf and a fire-proof glass on the door leaf. The utility model is characterized in that the fire-proof sealing devices are arranged around the doorframe, in the centre joint of the door leaf and around the fire-proof glass. The utility model has the advantages that when the fire breaks out, the smoke flowing and the flame spreading are able to be effectively held back. Because sealing strips are arranged around the doorframe, in the centre joint of the door leaf and around the fire-proof glass. Thereby, the loss caused through fire is furthest reduced.
Description
Affiliated field:
The utility model belongs to a kind of fire protection equipment, but particularly a kind of steel casement door of fire-proof smoke-proof.
Background technology:
In fire because along with the spreading of flame, the speed of Flue Gas Diffusion is very fast.Introduce according to the high building fire fighting design manual, fire initialization phase in highrise building, the speed that the flue gas that produces because of cross-ventilation spreads in the horizontal direction is 0.3m/s; Burn the fierce stage at fire, the Flue Gas Diffusion speed that produces owing to the high temperature action thermal convection current is 0.5m/s--0.8m/s.And use finishing material to strengthen flue gas concentration more and more in the building now.In recent years in the fire disaster that the nationwide takes place, the injures and deaths that cause and the proportion of loss increase gradually because flue gas suffocates.And existing fire resistance steel door is also existing certain defective for preventing on the hood on the overall structure.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, both can prevent fires and provide a kind of, but the steel casement door of Smoke prevention again.
The technical solution of the utility model is: but a kind of steel casement door of fire-proof smoke-proof form by the flame resistant glass on doorframe, door leaf and the door leaf, it is characterized in that: but around doorframe, around the centre joint place of door leaf and the flame resistant glass, the fireproof sealing device is housed.
But the weather strip of above-mentioned fireproof sealing device for making with fire-retardant expanded rubber.
The utility model has the advantages that; Because weather strip is housed around the flame resistant glass on doorframe, the door leaf centre joint and the door leaf of labeled door, therefore when breaking out of fire, can stop flowing of flue gas effectively, spreading of flame reduces the loss that fire causes to greatest extent.

Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is the A-A sectional drawing of Fig. 1
Fig. 3 is the B-B sectional drawing of Fig. 1
Fig. 4 is the C-C sectional drawing of Fig. 1
The specific embodiment:
But a kind of steel casement door of fire-proof smoke-proof is made up of the flame resistant glass on doorframe 1, door leaf 2 and the door leaf 3, it is characterized in that: but around doorframe, around the centre joint place of door leaf and the flame resistant glass, fireproof weather strip 4,5,6 is housed respectively.But above-mentioned fireproof weather strip is what make with fire-retardant expanded rubber.When breaking out of fire, weather strip expands, and has fire insulation every hood, can stop flow of flue gas effectively, and spreading of flame reduces the loss that fire causes to greatest extent.
Claims (2)
- But 1, a kind of steel casement door of fire-proof smoke-proof is made up of the flame resistant glass on doorframe, door leaf and the door leaf, it is characterized in that: but around doorframe, around the centre joint place of door leaf and the flame resistant glass, the fireproof sealing device is housed.
- But 2, the steel casement door of fire-proof smoke-proof according to claim 1 is characterized in that: but the weather strip of above-mentioned fireproof sealing device for making with fire-retardant expanded rubber.
