Abstract
The utility model relates to a hard inorganic fiber spraying fire-prevention isolation strip which is horizontally arranged on the surface of a building outer wall, the two sides of the isolation strip are equipped with thermal insulation materials, and the surface of the fire-prevention isolation strip and the surface of the thermal insulation materials are equipped with covering layers. The isolation strip is characterized by comprising a connecting interface layer, a hard inorganic fiber spraying layer and a surface strengthening layer, wherein the width of the fire-prevention isolation strip is 300mm-550mm, and the thickness of the fire-prevention isolation strip is 20mm-50mm. The fire-prevention isolation strip all adopts inorganic materials, has fine performance of fire prevention, thermal insulation and water repellency; meanwhile by adopting the spraying process, the fire-prevention isolation strip has the advantages of simple and convenient construction and high work efficiency.
Description
Technical field
The utility model relates to the fire barrier in a kind of skin outer heat preservation system, has the hard inorfil sprayed fire proofing isolation strip of fire prevention, waterproof, heat insulation function specifically.
Background technology
At present, the method that extensively adopts in China's external wall of high-rise building outer heat preservation system is the exterior wall paste polystyrene foamed plastic plate at building, is commonly called as polyphenyl plate, benzene plate or extruded sheet.Polystyrene is that combustible material is in case burning is puted out a fire to save life and property very difficult, to cause great loss to the people masses' property, so in the national departments concerned regulation external wall of high-rise building outer heat preservation system fire barrier should be set, greater than 60 meters buildings less than 100 meters, every layer should be provided with horizontal fire barrier as height; Height is greater than 24 meters, less than 60 meters building, every two-layer horizontal fire barrier should be set; Highly less than 24 meters building, per three layers should be provided with horizontal fire barrier.The making of fire barrier at first should be considered fire prevention, also good heat-insulating property to be arranged in addition, to avoid thermal conductivity with heat insulating material to have big difference and " heat bridge " to occur, the preparation method of fire barrier has installs flame retardant polyurethane foamed fireproofing isolation strip between polyphenyl plate, the flame-retardant polyurethane expanded material is difficult to reach the requirement of fire prevention A level, and the fire prevention isolation effect is limited; The rock cotton board fire barrier is installed between polyphenyl plate, and rock wool is that inorganic material A level is not fired, but the water imbibition of rock wool is very strong, and ambient humidity is excessive, and as the experience sleety weather, rock wool suction back heat-insulating property will obviously descend.
Summary of the invention
In order to solve the not good and rock cotton board fire barrier of the flame retardant polyurethane foamed fireproofing isolation strip flameproof effect problems such as heat-insulating property difference that absorb water easily, the utility model provides a kind of hard inorfil sprayed fire proofing isolation strip with fire prevention, waterproof, heat insulation function.
The technical scheme that its technical problem that solves the utility model adopts is:
The fire barrier is made up of linkage interface layer, hard inorfil sprayed coating, surface strengthen layer and overcoat.
In the building exterior wall surface design linkage interface layer, the function of linkage interface layer being arranged is the adhesive strength that improves between exterior wall and the hard inorfil sprayed coating, and main component is water-reducible low concentration of water mud, and thickness is 1mm～10mm.It on the linkage interface layer hard inorfil sprayed coating, function is insulation, fire prevention, main component is granular rock wool and cement, thickness can be decided according to the thickness of adiabator layer, is generally 15mm～140mm, and hard inorfil sprayed coating fireproof performance is good, and thermal conductivity is at 0.040～0.045W/ (mK), heat-insulating property and heat insulating material are close, avoid " heat bridge " to occur, and have the cement isolation to have water-proof function around the granular rock wool.Be surface strengthen layer on the hard inorfil sprayed coating, function is to improve surface strength, and main component is water-reducible high concentration water's mud, and thickness is 1mm～10mm.Whole fire barrier is inorganic material, fire prevention A level.
The beneficial effects of the utility model are that the heat-insulating property of fire barrier is suitable with the heat-insulating property of common heat insulating material, " heat bridge " can not occur, organic material is not contained in whole fire barrier, fireproof performance is good, adopts spraying coating process simultaneously, simple and convenient, high efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of this fire barrier.
Fig. 2 is the position is used in this fire barrier at external wall a schematic diagram.
1. floors among the figure, 2. exterior wall, 3. insulation layer, 4. topping, 5. linkage interface layer, 6. hard inorfil sprayed coating, 7. surface strengthen layer, 8. fire barrier, 9. window.
The specific embodiment
In Fig. 1, floor (1), exterior wall (2) are the enclosed structure of building, and at the external surface paste heat-preserving material extruded sheet of the exterior wall of building (2), extruded sheet thickness is 80mm, and horizontal direction is reserved the wide distance of 350mm the fire barrier is set between the extruded sheet.The cement paste of spraying tap water dilution in 10: 1 on the external surface 350mm of exterior wall (2) bandwidth reservation position, coating thickness 2mm, form linkage interface layer (5), surperficial coated with hard inorfil sprayed on material at linkage interface layer (5), hard inorfil sprayed on material is special-purpose granular rock wool of spraying and cement paste, the ratio of water and cement is 3: 2 in the cement paste, and the thickness of spraying is 70mm, and hard inorfil sprayed coating (6) forms.At the cement paste of the surface of hard inorfil sprayed coating (6) spraying tap water dilution in 1: 1, coating thickness 3mm, surface strengthen layer (7) forms, then in temperature greater than 4 ℃, relative humidity was less than air dry in 50% the environment 72 hours.Criticize on the surface of insulation layer (3) and surface strengthen layer (7) and to touch the grid cloth anticracking grout; thickness 6mm, then in temperature greater than 4 ℃, relative humidity was less than air dry in 50% the environment 72 hours; topping (4) forms, and fire barrier and whole external thermal insulation system are made and finished.Also can make the fire barrier in the specific implementation process earlier and then heat insulating material is installed; if the thickness of hard inorfil sprayed coating (6) is greater than 70mm; then should spray at twice; thickness as hard inorfil sprayed coating (6) is the then first spraying 70mm of 100mm; for the second time spray 30mm, the surface of insulation layer (3) and fire barrier (8) can also be criticized incombustible materials such as touching leveling mortar or sticking brick and be served as topping (4).
Fig. 2 is that the schematic diagram at position is used at external wall in this fire barrier, and every layer is provided with horizontal fire barrier (8) in the building, and fire barrier (8) are in the below or the top of window (9).
