Abstract
The utility model discloses shutter pieces for a fireproof roller shutter door. The fireproof roller shutter door comprises a roller shutter formed by serially connecting shutter pieces, a fireproof bag for storing fire extinguishing agent is arranged in a casing of each shutter piece, a plurality of spraying nozzles communicated with the fireproof bag is arranged on the outer surface of the casing, and an expansion type fireproof coating layer is arranged on the outer surface of the casing. The shutter pieces have the advantages that aqueous film forming foam extinguishing agent is filled in the fireproof bags in the shutter pieces and covers the shutter pieces after being sprayed out to have the function of heat insulation, temperature reduction and oxygen insulation; the liquid aqueous film forming foam extinguishing agent takes away heat after being sprayed out, temperature rising speed of the shutter pieces is lowered down further, and service life is prolonged; when foam volatilizes up, the expansion type fireproof coating layer is triggered to expand and foam to form foam which can insulate oxygen and heat, endothermic reaction is performed due to volume expanding during expansion, heat in burning is consumed, temperature of the system is lowered down, and service life of the shutter pieces is effectively prolonged.
Description
Technical field
The utility model relates to rolling door technical field, is specifically related to the rolling shutter for fire resistance rolling shutter door.
Background technology
Rolling shutter for fire resistance rolling shutter door is a kind of fire prevention, heat insulation facility that is applicable to place, the larger hole of building, and product has adopted the built-in feature of spool in design, has compactness rational in infrastructure.The roller shutter that is used for the rolling shutter of fire resistance rolling shutter door reaches the lifting of roller shutter by transmission device and control system.Play fire prevention, fire insulation effect, smooth attractive in appearance, the modern design of product design, has rigidity strong.The fireproof partition district that is widely used in industry and civilian construction for the rolling shutter of fire resistance rolling shutter door, can stop fire spreading effectively, ensures the security of the lives and property, is indispensable fireproofing in modern architecture.
Existing rolling shutter adopts the inner fire-proof heat-insulating material of filling, as the mode of asbestos realize get angry heat insulation.Such structure makes side towards the fire directly contact flame, and inner fire-proof heat-insulating material of filling can only play isolated thermal-radiating effect, and because shell is metal material, thermal conductivity coefficient is high, and unexposed surface temperature rise is fast, and whole fireproof performance is unsatisfactory.And side towards the fire is because of direct contact flame, temperature is high, and intensity can not get ensureing.The mechanical strength of steel reduces with the rising of temperature, and 500 ℃ of left and right, its intensity drops to 40%～50%, intensity total loss in the time of 700 ℃.Therefore, with adopting steel, also differ and adhere to surely official hour in time.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide a kind of rolling shutter for fire resistance rolling shutter door, and to overcome outside the roller shutter of existing rolling shutter is directly exposed to, inner fire-proof heat-insulating material effect of filling is bad, thereby affects the problem of working life.
For reaching foregoing invention object, the technical scheme that the utility model adopts is: a kind of rolling shutter for fire resistance rolling shutter door is provided, comprise shell, be provided with for storing the fire prevention bag of extinguishing chemical in described shell, described outer surface of outer cover is provided with the shower nozzle of several and described fire prevention bag UNICOM.
The connection that described shower nozzle arranges by its lower end is connected through described shell and with fire prevention bag; Described connection is connected with the lower end of main channel in being arranged on shower nozzle, and the upper end of main channel is connected with at least one branched bottom, and the surface that branched bottom extends outwardly into shower nozzle forms spout.
Described branched bottom is provided with 6～8.
Described outer surface of outer cover is provided with expanding fire-proof paint layer.
Described shower nozzle is arranged on the bottom of shell.
In sum, this rolling shutter tool has the following advantages:
1, the fire prevention arranging in rolling shutter wraps in during Initial Stage of Fire, its in-built aqueous film-forming foam extinguishing agent heats up and expands, and burst to prevent fires and wrap the prefabricated cut of setting, by shower nozzle, to shower nozzle surrounding, spray again, cover on roller shutter, play the effect of heat insulation, cooling and starvation, before fire foam is evaporated, can play a protective role always;
2, the in-built aqueous film-forming foam extinguishing agent of fire prevention bag is liquid, and specific heat strengthens, and heats up slower, and can also take away heat after its ejection, and rolling shutter temperature rise speed is further declined, and extends working life;
3, at fire, occur after latter 30 to 200 minutes, foam volatilization totally, rolling shutter shell is directly exposed in high-temperature gas, even directly contacts flame, and now temperature can raise rapidly, then trigger expanding fire-proof paint layer, trigger expanding fire-proof paint layer expanded foamed, form froth bed, froth bed has not only completely cut off oxygen, and because its quality is loose, there is good heat-proof quality, can retardation heat be transmitted to the speed of protected base material; According to physical and chemical principle analysis, the process of the froth bed of the expanded foamed generation of coating presents the endothermic reaction because volume expands, heat while also having consumed burning, be conducive to reduce the temperature of system, the effect of these aspects, make the fire-proof and thermal-insulation effect of expanding fire-proof paint layer very good, the working life that has effectively extended this rolling shutter.
