Description
Technical field
The present invention relates to a kind of composite thermal-insulating wall fire protection construction, particularly a kind of have the external heat insulating composite wall that satisfies fire endurance requirement supporting and topping to construct.
Background technology
The problem that body of wall energy-saving heat preserving technology exists not only affects the effect of building energy conservation, affect the low-carbon (LC) social construction, its safety also affects the safety of people's lives and properties, the fire savety problem of poor that the thin heat-preserving wall of plastering exists has fire to occur when causing various places, and fire causes heavy losses to society.
Because the thin only 3～4mm of heat-preserving wall protective layer thickness that plasters, too little to the resistivity of fire, even 300mm rock wool fire barrier is set, the fire barrier role is very little.The fire test that is undertaken by Tianjin Fire Research Station, Sichuan Fire Research Station as seen, flame height reaches 2～3 meters, crosses very soon the high horizontal fire barrier of 300mm, and the insulation layer more than the fire barrier is burnt.The fire that organic insulation material produces on the body of wall is " Hong combustion ", and only a few minutes big fire is just surrounded whole building, has little time to put out a fire to save life and property at all.Because the thin topping of plastering does not have resistant function to flame, can not bring into play the effect of fire barrier.The fire prevention sequestered partition that arranges on the thin heat-preserving wall of plastering is referred to as open fire prevention sequestered partition structure, and arranging of its fire barrier is unscientific at all.
What cracking came off behind the thin heat-preserving wall completion of works of plastering of China can be found everywhere, and quality preferably engineering causes insulation layer to be directly exposed in the air also at 7～8 years crackings.This not only greatly affects the durability of energy-saving heat-insulating wall, and maintenance capacity is large, and building waste is many, the sustainable development of impact society, and further increased the danger that fire occurs.
All belong to high energy consumption, high pollution industry owing to produce inorganic heat insulation material, price is high, unfavorable control room rate, and the energy-saving heat preserving effect is not as organic insulation material, therefore no matter be current or future, inorganic heat insulation material should not be the main product of wall heat insulation material, organic insulation material or wall heat insulation material main product.
Guarantee that the external heat insulating wall fire safety had both needed qualified organic insulation material and strict execution control, also need to have the building fire protection structure of science, like this safety of guarantee external heat insulating wall in long-term use procedure.
Other energy-saving wall technology be used for the fixing interior wire lath of external protection the connector poor rigidity, do not prevent fires, as:
Be provided with wire lath in the topping of glue powder polyphenyl particle energy-saving heat-insulating body technique, being connected with base course wall is with the lentor nail wire lath and base course wall to be fixed.(this plastics connecting bridge is the plastic sheet of the about 3mm of thickness, the about 30mm of width with the plastics connecting bridge among the provincial standard DB23/1167 of Heilongjiang Province, two ends are with bayonet socket) will fix with benzene plate module and the cast-in-situ concrete of dovetail groove, this plastics connecting bridge is used for the gauze wire cloth in the thick floated coat of fixed outer 22mm simultaneously.The rigidity of lentor nail and plastics connecting bridge is all bad, benzene plate atrophy when particularly catching fire, and lentor is followed closely and the also very fast thawing of plastics of plastics connecting bridge, the outside danger that topping still can come off of plastering.This explanation, current these energy-saving heat-insulating body techniques generally do not solve the safety problem of external protection when catching fire.
Applicant has proposed following patent, sees attached list.The insulation layer of composite thermal-insulating wall has the thick topping of plastering outward in the subordinate list, by the adjustment protective layer thickness of plastering, can satisfy the different endurances of fire protection requirement.With reference to steel wire net rack cement filled board fire test data: steel wire web-cement polystyrene sandwich board is configured in does not have flame radiation in the actual fire, the integral combustion performance of steel wire web-cement polystyrene sandwich board can be identified as incombustible material, and fire endurance is 1.2 hours (25mm plasters).The combined wall that is provided with the thick topping of plastering is compound (sandwich) body of wall that a kind of combustibility can reach the A level.

A kind of key technology difference and technique effect that has the external heat insulating composite wall that satisfies fire endurance requirement supporting and topping and the thin heat-preserving wall of plastering that rock wool fire barrier and other energy-saving wall technology are set of the present invention:
1, claim 1 of the present invention and 5 supportings are for satisfying the supporting of fire endurance requirement; and there is the combined wall that satisfies the claimed layer of fire endurance all other outsides at present; the supporting of satisfying the fire endurance requirement all is not set; the safety of external protection when being used for guaranteeing to catch fire, applicant publication technology also do not propose to satisfy the requirement of fire endurance to supporting.
When for example satisfying the topping of fire endurance requirement with continuously connected fastener or peg or other plastic fastening fixed outer; when fire occurs; may be because continuously connected fastener or peg or other plastic fastening fire endurance be inadequate; cause sag of protecting coating; the intensity of a fire is enlarged; the organic heat-insulating melting layer melts to drip the fire fighter is threatened after the sag of protecting coating; make it to be difficult to stamp out a fire, still dangerous with the energy-saving heat preserving combined wall structure fire prevention that continuously connected fastener or peg or other plastic fastening are connected with topping.
And the present invention hangs topping with the supporting of satisfying the fire endurance requirement; in the fire endurance time range; melt and drip by the thick curtain wall closing of plastering, can not occur that sag of protecting coating, the intensity of a fire enlarge, the melting to drip and the fire fighter is threatened the phenomenon that can't stamp out a fire of organic heat-insulating melting layer.That is to say that not only topping will satisfy the fire endurance requirement, and need to have the supporting of satisfying the fire endurance requirement topping to be connected the effect of competence exertion topping with major structure of construction or base course wall.
2, topping of the present invention satisfies the fire endurance requirement.
And the topping of the thin heat-preserving wall of plastering does not satisfy the fire endurance requirement, when fire occurs, even the fire barrier is set; because the thin topping of plastering is not resisted the fire ability, flame can not by shutoff in limited range, be a kind of open fire barrier; the influence of fire scope is large, and harm is large.
3, claim 2 of the present invention and 6 also arranges the fire barrier in the composite thermal-insulating wall insulation layer, thereby can form a kind of closed fire compartmentation structure, greatly reduces fire damage.
