Description
Technical field
Proposed by the present invention is a kind of fire resisting steel construction load-bearing pillar of building field application.
Background technology
Load-bearing pillar is in steel structure frame and its important, if burnt in advance when fire is met with, steel construction can be accelerated whole
Collapsing for body framework, can cause inevitably injury.
The load-bearing pillar of steel construction is currently used for for exposed steel body, the effect without radiating and fire resisting, thus needing fire prevention
Be not suitable for using with fire-retardant occasion.
The content of the invention
In order to make the fire resisting of load steel structure post and radiating, the invention provides a kind of fire resisting steel construction load-bearing pillar.Should
Load-bearing pillar by the application hexagonal boron nitride coating on the outside of steel column, in coating outer wrap multi-walled carbon nano-tubes, and in steel knot
Structure column top sets temperature sensor, solves steel structure column fire-retardant with fireproof technical problem.
The present invention solves the scheme that is used of technical problem：
Hexagonal boron nitride coating is scribbled on the outside of the steel structure column of cylinder or square-section and abnormity, heat conduction is formed and is applied
Layer, is provided with inorganic heat preservation body outside hexagonal boron nitride coating, and many wall carbon are set with inorganic heat preservation external body winding parcel
Nanotube, fire alarm temperature detector is equipped with the steel structure column top side of multi-walled carbon nano-tubes winding parcel；
In described fire alarm temperature detector built with chip, hygrosensor is connected with chip circuit, and circuit point is drawn on chip
It is not connected with audible-visual annunciator and fire alarm transmitter.
The hexagonal boron nitride coating, is that hexagonal boron nitride powder is dispersed in organic or inorganic cementing agent, is stirred
Constitute afterwards, be applied on the outer layer of steel structure column.
The inorganic cementing agent uses waterglass or sodium metasilicate.
Organic cementing agent uses silicone acrylic emulsion.
The inorganic heat preservation body uses expanded perlite, rock wool or silico-calcium fiber.
Good effect, steel structure column of the present invention can strengthen the refractory ability of load-bearing pillar so that steel construction can be in fire
Stability is kept during generation, the service life of steel construction load-bearing pillar is increased.The suitable steel construction load-bearing as steel building
Post application.

Fig. 2 is present invention alarm temperature detector schematic diagram.
In figure, 1. steel structure column, 2. hexagonal boron nitride coating, 3. multi-walled carbon nano-tubes, 4. fire alarm temperature detector, 5. inorganic guarantor
Wen Ti, 4.1. chip, 4.2. hygrosensors, 4.3. audible-visual annunciators, 4.4. fire alarm transmitters.
Specific embodiment
According to the figure, hexagonal boron nitride is scribbled in the outside of cylinder or the steel structure column 1 of square-section and abnormity to apply
Layer 2, forms heat conducting coating, and inorganic heat preservation body 5 is provided with outside hexagonal boron nitride coating, is wound in inorganic heat preservation external body and wrapped
Wrap up in and be set with multi-walled carbon nano-tubes 3, fire alarm temperature detector is housed in the steel structure column top side of multi-walled carbon nano-tubes winding parcel
4；
In described fire alarm temperature detector built with chip 4.1, hygrosensor 4.2 is connected with chip circuit, is drawn on chip
Circuit is connected with audible-visual annunciator 4.3 and fire alarm transmitter 4.4 respectively.
The hexagonal boron nitride coating, is that hexagonal boron nitride powder is dispersed in organic or inorganic cementing agent, is stirred
Constitute afterwards, be applied on the outer layer of steel structure column.
The inorganic cementing agent uses waterglass or sodium metasilicate.
Organic cementing agent uses silicone acrylic emulsion.
The inorganic heat preservation body uses expanded perlite, rock wool or silico-calcium fiber.
Know-why：
Hexagonal boron nitride coating outside steel structure body has structural rigidity, while the also title with white graphite, with similar
The layer structure of graphite, there is good anti-flammability, oxidation resistance, electrical insulating property, thermal conductivity and chemical resistance.
The multi-walled carbon nano-tubes of hexagonal boron nitride coating outside parcel also has high intensity and big toughness, while having resistance to
Fire and thermal diffusivity.
Show, CNT has quick heat radiating capability that itself there is burning resistance, even fired state according to data
Also carbon protective layer can be produced, the heat sink material can radiate in time, prevents outside heat from internally conducting, the steel knot inside protection
Structure.
So the hexagonal boron nitride coating and multi-walled carbon nano-tubes outside steel structure column be allowed to have it is comprehensive it is fire-retardant with
Fire resistance, and send sound and light alarm signal by fire alarm, fire alarm point position is detected by monitoring equipment, with profit and
When take fire suppression measures.
The chip has Temperature Treatment function, and high temperature is compared with normal temperature, alarm temperature value is set, when reaching fire
During calamity temperature, audible-visual annunciator is sent sound and flashed with light, point out surrounding control point warning message, and believe by fire alarm
Number transmitter sends alarm signal, and alarm signal is received with sharp monitoring equipment, is put out a fire in time, prevents fire from expanding.
Advantage：
The present invention has heat conduction and fireproof performance, can send fire alarm signal, suitably should as the load-bearing pillar of steel construction
With.
