Description
Technical field
The utility model relates to external wall flammability test technical field, specifically a kind of analogue experiment installation for external wall fire proof construction and performance thereof.
Background technology
Along with Chinese society rapid economic development and Development of China's Urbanization deepen continuously, (surpassing) skyscraper is increasing.Ground at present total nearly 200,000 skyscrapers in China, wherein high-rise building has nearly more than 3000, and fast-developing interdependent what accompany is the serious fire safety evaluating problem that it brings with skyscraper.
The use of exterior wall organic insulation material can reduce energy resource consumption to a certain extent, and the living environment of a relative comfort is provided to resident, but the use of a large amount of flammable external-wall heat-insulation material also brings great fire safety evaluating hidden danger, and the disaster brought is inestimable especially.At present, a large amount of uses of flammable and inflammable external-wall heat-insulation material, make the fire accidents accident caused by facade fire spread frequently occur; Secondly, high-rise building with fire disaster, between building interior is vertical flame and fire and smoke spread very fast, in also being formed by the burning of building external flammable alien invasion-outer-Nei large-scale 3 D fire that mutually spread, difficulty of putting out a fire to save life and property is large.
Fire of high-rise building has much new feature causing in calamity mechanism and behavior, has many technical barriers urgently to be resolved hurrily in prevention and control.First, external-wall heat-insulation material is widely used in skyscraper, becomes one of important channel reducing building energy consumption.Conventional exterior wall organic insulation material, as polystyrene and hard bubble polyurethane exterior wall thermal insulation material etc., although have superior properties of heat preservation and energy saving, but these insulation materials are flammable, flame spread rates is rapid, simultaneously a large amount of poisonous and harmful flue gas again, causes great potential safety hazard.Moreover complicated building structure and boundary condition can bring special fire evolved behavior.The structure of skyscraper and boundary condition complexity, pipe network is crisscross, the fire spread of the appreciable impact skyscraper inside such as chimney effect, Piston Action Wind formed in the vertical passageways such as stairwell, elevator, piping shaft and flue gas transport process are the major reasons causing the severely injured major break down of the dead group of group.When inside fire causes glass curtain wall to break, will form the overflow of alien invasion opening fire, fire brings serious threat to the structural safety of skyscraper.Finally, fire brings serious threat also to the structural safety of skyscraper.Glass curtain wall structure, steel construction and large area lamp box billboard have become the important feature form of the modern building complexes such as skyscraper, the mechanics load assignment of these structures itself is just very complicated, its key member and node are under the effect of the non-homogeneous strong heating stream of fire, be easy to expansion lost efficacy and the local or the total collapse that cause building structure, form great fire secondary disaster, cause catastrophic effect.
Current China " Code for fire protection design of buildings " (GB50016-2006) and " Code for fire protection design of high rise buildings " (GB50045-95 2005) does not formulate for the fire preventing external-wall heat-insulation material to cause first to close provision, the particular content of the design for external wall fire proof construction is not all proposed in regulation, even if up-to-date " Code for fire protection design of buildings " (GB50016-2014) also only claims to the burning performance of the insulation material adopted when covil construction exterior-wall heat insulation and its decoration, specified in more detail is not had to external wall fire proof construction.On February 10th, 2012, the firmly portion's of building just " about carrying out State Council about the notice strengthening and improve firemanic suggestion " External Wall insulation material requirement: " strengthen new building supervision; the regulation about insulation material burning performance in strict implement " covil construction exterior wall heat-preserving system and decoration of exterior wall fire prevention temporary provisions "; when particularly adopting B1 and B2 level insulation material, fire-blocking belt should be set according to the rules." exterior-wall heat insulation isolation strip and insulation material proportion unit, only have the Ministry of Public Security, house and town and country construction portion No. 46 documentation requirements in 2009.Fire prevention and control are unfavorable for from large scale window fire experiment this standard known.Be difficult to reinstall according to current law to the building with external thermal insulation system, corresponding notice, legal norm its request for utilization not clear and definite.
In addition, the external structure that skin is intrinsic, such as balcony, window still wall, similar horizontal baffle structure and the vertical baffle structure such as to cornice, self have certain width and length, such building structure to a certain extent External Wall heat-insulation system fire behavior has a certain impact and corresponding flameproof effect.The anti-fire behavior of corresponding construction does not have concrete research and corresponding fire test, lacks data supporting and the experimental verification of these aspects.Therefore, be necessary for the external structure of different kinds of building exterior wall carry out strengthen Building Fire Protection structure fundamental research and on building external architecture basics to the influence research of Surgery therapy fire behavior, obtain relevant data supporting, for the fire protection design of skyscraper alien invasion heat-insulation system provides useful guidance and reference, also for the streak specifications such as Fire Fighting in Tall Buildings and structural design provides strong theoretical direction and technical support.
Due to complicacy and the uncertainty of fire phenomena, need the thought by introducing similarity theory, fire process under the various factors coupling effect of actual complex is reduced to the small-scale experiment research that factor of influence is single, condition is controlled, thus the complicacy simplified in actual fire, reduce experimental cost, operability is simple, improves assay reproducibility.Therefore, external wall fire proof construction, fire protecting performance analogue experiment installation need based on small-medium size experiment, the fire protecting performance of the components such as outstanding fire-blocking belt, horizontal baffle, vertical baffle and to the simulated experiment of outer heat preservation system fire behavior and research.
Though there is partial document to propose similar research and design in prior art, external wall fire proof construction, fire protecting performance simulated experiment needs all cannot be met.If number of patent application is the patent document of 200910184963.0, disclose a kind of simulation experiment device of fire disaster on external wall face of urban building, it is by the design of slope board, the impact of the indoor overflow fire of primary study on buildings outside wall surface, and adjoin experiment and the research equipment of the fire behavior under the limited situation of hillside fields, the impact of inclined-plane on buildings focusing on buildings outside of research, cannot be used for the fire proof construction such as fire-blocking belt, horizontal baffle, vertical baffle of simulant building thing itself.
Number of patent application is 20101058927.9 also disclose a kind of skin heat-insulation system fire test device, the fire spread rule of this device research skin insulation material self and fire spread braking measure, research emphasis be fire spread under skin structure influence dynamically and rule, but not the research of fire proof construction performance, therefore cannot carry out the simulated experiment of fire proof construction equally.
How to develop a kind of analogue experiment installation of small-medium size research external wall fireproof component that utilizes and become the technical matters being badly in need of solution.
