Description
Technical field
The utility model belongs to metal support member technical field, more particularly to a kind of fire preventing steel structure for building.
Background technology
Steel construction is one of main building structure, because its intensity is high, from heavy and light, manufacture is easy, speed of application is fast, plasticity and
The features such as good toughness, the extensive use in industry, civil buildings.Steel are a kind of construction materials that will not be burnt, and it has anti-
The characteristics such as shake, bending resistance.In actual applications, steel be able to can also both meet to build with the weight bearing power of relative increase building
The needs of aesthetic feeling of the design moulding, it is thus also avoided that the construction material such as concrete can not be bent, the defects of stretching.Therefore steel construction by
The favor of building trade, individual layer, multilayer, skyscraper, factory building, storehouse, waiting room, boarding lounge etc. is all very general using steel
Time.
But steel as construction material in terms of fire prevention again be difficult to avoid that in the presence of some the defects of, its mechanical performance,
Such as yield point, tension and modulus of elasticity can drastically decline because of the rise of temperature, can be fast under high temperature due to its easily heat conduction
Speed is heated to be lost intensity and deforms.When heating temperature reaches more than 250 DEG C, its intensity declines quickly, reaches 600 DEG C when heated
When, intensity only remaining 1/3, and general fire scene temperature may be up to more than 700 DEG C.As construction material, the fire endurance of steel is only
For 15 minutes or so, thus under high temperature of fire effect, steel construction can lose bearing capacity because reaching its fire endurance quickly
And fail, cause building part or all collapse breaking-up and lead to secondary accident.Therefore must take measures, to steel construction
Flameproof protection is carried out, the purpose of steel structure fireproof protection is that the fire endurance of steel construction is increased into fire prevention by 0.25 hour sets
Fire endurance as defined in counting specification, prevent steel construction to be brought rapidly up being deformed in a fire so that collapse, so as to for fire extinguishing and
Safety evacuation wins the quality time, avoids or reduce fire damage.
Utility model content
The purpose of this utility model is providing a kind of fire preventing steel structure for building, improves the fire protecting performance of steel construction, avoids
Steel construction rapid be heated when fire occurs loses intensity and deformed.
In order to achieve the above object, base case of the present utility model is：Fire preventing steel structure for building, including water storage box,
Water pipe, heat transfer aluminum strip and I-steel main body, the web both sides of the I-steel main body are equipped with the water storage cavity surrounded by fire-proof plate,
The sliding block that water storage cavity is divided into top box layer and nowel layer is slidably connected in water storage cavity；One end of the heat transfer aluminum strip passes through upper
Case layer and in the top box layer, the other end is located at outside top box layer；The nowel layer connects built with water between nowel layer and sliding block

Spring state in which when referring to spring only by the external force of sliding block application in the state of nature.
The operation principle of this base case is：Aluminium has the characteristics of heat conduction is fast, and the gas in top box layer can pass through biography
Hot aluminum strip carries out heat exchange with extraneous.Gas in top box layer absorbs heat by the aluminum strip that conducts heat, and gas heat absorption expansion, promotes and slides
Block moves downward.In general, the temperature of external environment will not be too high, thus the gas expansion degree in top box layer compared with
It is small, it is difficult to overcome the resistance of spring to promote sliding block to move downward, therefore maintained a relatively stable state in water storage cavity.It is special when occurring
During different situation, fire such as occurs, ambient temperature rapidly raises, and the gas in top box layer absorbs extraneous heat by the aluminum strip that conducts heat
Amount, gas heat absorption expand rapidly, and sliding block overcomes the resistance of spring to move downward.Due to the compression of sliding block, the pressure in nowel layer
Raise, now one-way exhaust valve is opened, and water sprays the external world by one-way exhaust valve, reduces the temperature of surrounding environment.When sliding block to
Under when moving to fixed position, steam vent is opened, and the gas in top box layer discharges extraneous, the pressure in top box layer by steam vent
Reduce, now under the thrust of spring, sliding block moves upwards.The volume increase of top box layer, pressure reduce, unidirectionally entering on water pipe
Water valve is opened, and the water in water storage box is added in nowel layer by water pipe.
The beneficial effect of this base case is：

Sprayed in one-way exhaust valve, water is sprayed in I-steel main body and the surrounding of I-steel main body, reduces environment temperature；And work as steam
During formation gas, vaporization heat absorption, environment temperature can be further reduced, strengthens the fire protecting performance of steel construction.
3rd, moved downward using the rapidly rise of ambient temperature, driving sliding block, the water in nowel layer is sprayed automatically
Go out, automaticity is high；Water can also be such that water is automatically replenished in nowel layer after spraying, and be not required to artificially add water, very convenient.
Further, the outer wall of the nowel layer is provided with thermal insulation layer.The setting of thermal insulation layer further reduces leading for nowel layer
Hot property, the capacity of heat transmission of top box layer is strong, and the heat conduction of nowel layer is weak, under ensure that top box layer gas expansion degree is significantly greater than
The gas expansion of case layer so that the gas of top box layer can promote sliding block to move downward.
Further, the cross section of the sliding block is arranged to " H " shape.The cross section of sliding block is arranged to " H " shape, on the one hand ensures
The stability of slide block movement, on the other hand ensure that sliding block can by vent hole seal.
Further, the nowel layer is provided with the shower nozzle that can spray water smoke, and the shower nozzle connects with one-way exhaust valve.Unidirectionally
After air bleeding valve is opened, the water in nowel layer can be sprayed by shower nozzle, the water of ejection into mist-like, water can fast vaporizing absorb
Heat, effectively reduce ambient temperature.
Further, the surface of the I-steel main body is coated with heat insulating coat.Be coated with the surface of I-steel main body every
Hot coating can further improve the fire protecting performance of steel construction.
Further, the both sides of the I-steel main body are equipped with reinforcement.The setting of reinforcement can strengthen steel construction
Intensity, avoid in the case where high temperature of fire acts on, steel construction is because reaching its fire endurance and rapid loss bearing capacity.
