Abstract

The utility model discloses a fireproof and temperature-reducing cooling bead. The bead is characterized in that the bead is formed by a bead housing (1) and cooling medium (2); the cooling medium (2) is enclosed in the bead housing (2); and the bead housing (1) is made of certainly temperature-resisting composite materials. When temperature of the cooling bead is higher than heat-resisting temperature of the composite materials, the bead housing (1) breaks and the cooling medium (2) flows out of the bead housing (1). The cooling bead is applied in a steel structure, so fire resistant rating of the steel structure is greatly increased, and time of fireproof ability is extended.

Description

A kind of fire prevention cooling down pearl

Technical field

The utility model relates to a kind of building fire protection cooling down pearl, is specifically related to a kind of fire prevention cooling down pearl that can use in beam column of steel structure.

Background technology

At present, high-rise steel structure building is increasing, some super highrise buildings especially, and the steel building material of employing is more extensive.But the defect that steel structure material has existence to be difficult to avoid aspect fire prevention, as reaching 600 degree left and right, steel work temperature can lose supporting capacity, there is significantly crooked, distortion, cause bed rearrangement building collapse, consequence will be very serious, as the U.S. World Trade Organization mansion in 911 events collapses, its main cause is exactly that steel structure fireproofing ability does not reach certain requirement.The Steel Fire Resistance Rating that does not add protection is only about 15 minutes; existing method of fire protection is mainly on steel work, to be coated with fireproof paint; and the fire endurance of fireproof paint is only about 2 hours; and after use in a few years; the aging fire resistance property that loses of meeting, causes bed rearrangement building to have great potential safety hazard.

Summary of the invention

Technical problem to be solved in the utility model is how on existing fire prevention basis, to improve the fire resistance rating of steel work, and extends the time limit of its refractory ability.

In order to solve the problems of the technologies described above, the utility model has designed a kind of fire prevention cooling down pearl, it is characterized in that institute is comprised of pearl housing 1 and cooling medium 2 in described fire prevention cooling down pearl, described cooling medium 2 is enclosed in described pearl housing 1, described pearl housing 1 is made by the composite material of certain heatproof, when the heatproof temperature of described fire prevention cooling down pearl temperature over composite material, described pearl housing 1 breaks, and described cooling medium 2 flows out pearl housings 1.

Described pearl housing 1 is made by the composite material of 100 to 150 degrees Celsius of heatproofs.

Described cooling medium 2 is water, refrigerating medium or fire prevention medicine.

Described cooling medium 2 also comprises non-flammable blowing agent.

Described pearl housing 1 profile can be made into the profile that needs fireproof structure to match.

Enforcement the utlity model has following beneficial effect: owing to there is no breaking out of fire at ordinary times; cooling medium is to be enclosed in pearl housing; its cooling capacity can continue to keep and mend easily to run off; and by being added with blowing agent in cooling medium the inside; when needs are cooling, pearl housing just breaks; cooling medium just flows out; and due to blowing agent wiping effect; cooling medium expands and is full of whole steel work inwall; can not reduce because of the minimizing of the water yield protected area; improve the fire resistance rating of structure, and extended the time limit of its refractory ability.

accompanying drawing explanation

Fig. 1 is the cross-sectional view of the utility model fire prevention cooling down pearl;

Fig. 2 is that the utility model fire prevention cooling down pearl is for the stereogram of H shaped steel or i iron;

Fig. 3 is the stereogram of the utility model fire prevention cooling down pearl during for square beam column.

the specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Fig. 1 is the cross-sectional view of the utility model fire prevention cooling down pearl, pearl is comprised of pearl housing 1 and cooling medium 2 fire prevention cooling down, described cooling medium 2 is enclosed in described pearl housing 1, fire prevention cooling down pearl housing 1, the composite material that adopts heatproof 100-150 degree, as polyurethane, the spherical shell of making, the intensity of housing can be selected according to actual conditions the opportunity of breaking, and cooling medium 2 adds blowing agent by water or refrigerating medium or the medicine of preventing fires and forms.By steel structure fireproofing cooling down pearl, within being positioned over beam column of steel structure, when breaking out of fire makes steel work temperature spend over 100, steel structure fireproofing cooling down pearl is broken and gradually under the effect of blowing agent, water or the refrigerating medium expansion of steel structure fireproofing cooling down pearl the inside are filled on steel work wall, make its cooling, reach the effect of fire prevention cooling, thereby extend the fire resistance period of steel work.

Fig. 2 be the utility model fire prevention cooling down pearl for the stereogram of H shaped steel or i iron, comprise steel structure fireproofing cooling down pearl 3, square steel Structure Beam-column 4, steel sheet 5, exhaust, putting hole 6.The utility model instantiation is by steel structure fireproofing cooling down pearl 3, within being positioned over square steel Structure Beam-column 4, with steel sheet 5, surrounding and protects and seal, and at the place, high position of square steel Structure Beam-column 4, is provided with exhaust, putting hole 6.While making steel beam, column temperature spend over 100 when breaking out of fire, inner steel structure fireproofing cooling down pearl 3 is broken, and under the effect of blowing agent, water or the refrigerating medium expansion of the inside are filled on steel work wall and steel sheet 5, its temperature is declined, reach the effect of fire prevention cooling, thereby extend the fire resistance period of steel work.

Fig. 3 is the stereogram of the utility model fire prevention cooling down pearl during for square beam column, comprises steel structure fireproofing cooling down pearl 3, H beam column of steel structure 7, exhaust, putting hole 6.The utility model instantiation is by steel structure fireproofing cooling down pearl 3, within being positioned over H beam column of steel structure 7, at the place, high position of H beam column of steel structure 7, is provided with exhaust, putting hole 6.When breaking out of fire makes steel beam, column temperature spend over 100, inner steel structure fireproofing cooling down pearl 3 is broken, and under the effect of blowing agent, water or the refrigerating medium expansion of the inside are filled on steel work wall, its temperature is declined, reach the effect of fire prevention cooling, thereby extend the fire resistance period of steel work.

Above disclosed is only a kind of embodiment of the utility model, certainly can not limit with this interest field of the utility model, one of ordinary skill in the art will appreciate that all or part of flow process that realizes above-described embodiment, and the equivalent variations of doing according to the utility model claim, still belong to the scope that utility model contains.
