Specific embodiment
The utility model embodiment discloses a kind of fire resistance steel door, for solving fire resistant doorsets fire line in the prior art
The technical issues of energy is poor, be easy to cause security risk.
In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and specific implementation
The utility model is described in further detail for mode.Obviously, described embodiment is only the utility model a part
Embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, fall within the protection scope of the utility model.
It please refers to Fig.1 to Fig.3, a kind of one embodiment packet of the fire resistance steel door provided in the utility model embodiment
It includes:
Door leaf 1 and doorframe 2；Door leaf 1 is attached with doorframe 2 by hinge, and is provided between door leaf 1 and doorframe 2
Fireproof expansion seal part；
Wherein, door leaf 1 is welded by the first steel plate 3 and the second steel plate 4, and the first steel plate 3 and the second steel plate 4 weld
It connects to form seal chamber；The first expanded pearlite rock beam 6 and the second expanded pearlite rock beam 7 are disposed in seal chamber；First expansion
Calcium carbonate wall 5 is provided between pearlite slab 6 and the first steel plate 3；It is set between second expanded pearlite rock beam 7 and the second steel plate 4
It is equipped with another calcium carbonate wall 5；
It should be noted that including a large amount of calcium carbonate, fire temperature one generated when occurring in calcium carbonate wall 5
As at 800 DEG C to 1000 DEG C, therefore, when a fire, high temperature can make Decomposition of Calcium Carbonate go out calcium oxide and carbon dioxide, and produce
Raw carbon dioxide can reduce the oxygen concentration in air, slow down the sprawling of the intensity of a fire, play the role of preliminary fireproof, and set
The the first expanded pearlite rock beam 6 for being placed in 5 rear of calcium carbonate wall can play good thermal insulation, prevent produced by scene of fire
Heat toward shifting outdoors.
The more glass that cooling water is housed are provided in space between the first expanded perlite and the second expanded perlite
The glass of glass pipe 8, the glass tube 8 is relatively thin, on the one hand can reduce the cost of production, on the other hand relatively thin glass holds when heated
Easily explosion may make the cooling water in glass tube 8 to be easier to flow out；One end of glass tube 8 is installed on the first expanded pearlite rock beam 6
Side, the other end of glass tube 8 is installed on the side of the second expanded pearlite rock beam 7, wherein glass tube 8 and the first expanded pearlite
The angle that rock beam 6 is formed by is 60 °；Each glass tube 8 is parallel to each other and all separated by a distance is configured；
It should be noted that when a fire, high temperature is born in fire resistant doorsets, glass tube 8 is easy explosion at high temperature, and
When angle formed by glass tube 8 and the first expanded pearlite rock beam 6 is 60 °, glass tube 8 is heated to be easiest to burst, the reason is that, high
Temperature is up heated up from the bottom of door, and when angle is 60 °, the gravity of cooling water adds effect of the high temperature to glass tube 8,
Glass tube 8 is easiest to broken, and after glass tube 8 is broken, the cooling water of 8 the inside of glass tube can be fallen, on the door in play
The sprawling of the intensity of a fire has been dragged slowly in certain cooling effect, and the expanded pearlite rock beam of two sides also functions to certain heat-blocking action, in fire
The early period of calamity, glass tube 8 can't rupture, when heat caused by fire can not be obstructed by only having arrived expanded pearlite rock beam, glass
Glass pipe 8 just will do it rupture, to flow out cooling water.
Optionally, the glass tube 8 in the present embodiment can be provided with a water injection hole on its surface, and operator can pass through water
Pipe connects water injection hole, and cooling water is injected into glass tube 8, then is sealed on water injection hole using plunger.
Further, in this embodiment the surface of calcium carbonate wall 5 be coated with one layer of epoxy resin fireproof coating；
It should be noted that carbonic acid can be further strengthened by being coated with epoxy resin fireproof coating on the surface of calcium carbonate wall 5
The anti-flammability of calcium wall 5；
Epoxy resin fireproof coating is the epoxy fireproof coating manufactured using epoxy resin as raw material, the mobility of epoxy resin
Good, bonding force is strong, high mechanical strength, it is to most of material such as timber, metal, glass, plastics, rubber, leather, ceramics, fibre
Dimension etc. has good bonding force；Epoxy resin after solidification has excellent chemical corrosion resistance, heat resistance, resistance to acid and alkali
And good electrical insulating property, secondly epoxy fireproof coating has splendid closure, and flame-retardant composition will not move to coat side, because
This its fire protecting performance is influenced smaller by time and environment.
Further, in this embodiment the first steel plate 3 and the surface of the second steel plate 4 be also coated with one layer of above-mentioned asphalt mixtures modified by epoxy resin
Rouge fireproof coating.
Calcium carbonate wall 5 and the first expanded pearlite rock beam 6 and the second expanded pearlite rock beam 7 in the present embodiment are by viscous
What the mode of conjunction was attached, specific adhesive is fire resistant adhesive.
Further, Fig. 1 and Fig. 2 are please referred to, the fire prevention expansion piece in the present embodiment can select fire-proof expansion seal strip；
The fire-proof expansion seal strip is set to the gap between door leaf 1 and doorframe 2；
It should be noted that when a fire, fire-proof expansion seal strip it is heated can automatic expansion, thus by door leaf 1 with
Clearance position between doorframe 2 fills up, it is therefore prevented that dense smoke caused by fire flows out outdoors.
Further, the surrounding outer wall of the door leaf 1 is pasted with the fire-proof expansion seal strip, similarly in this position anti-
Fiery expanding sealing strips also for prevent dense smoke outflow outdoors.
It further, is to be provided with buzzer on fire resistance steel door in embodiment in itself；The buzzer can issue point
Sharp sound, the buzzer are connected with a temperature sensor, when the temperature that temperature sensor is sensed is than or equal to facing
When dividing value, buzzer then starts, and issues sound, informs that surrounding population has fire.
Further, the first steel plate 3 and the second steel plate 4 are the cold rolling zinc steel plate of thickness 0.8mm.
Fire resistance steel door in the present embodiment is applicable to underground parking, large-scale public place, classroom etc..
A kind of fire resistance steel door provided by the utility model is described in detail above, for the general of this field
Technical staff, based on the idea of the embodiment of the present invention, there will be changes in the specific implementation manner and application range,
In conclusion the content of the present specification should not be construed as a limitation of the present invention.
