Description
Technical field
The utility model relates to a kind of fireproof steel structure, more particularly refers to be provided with in the periphery of shaped steel the steel work of insulation insulated fire plate body.
Background technology
Steel (particularly section bar such as square steel, round steel, steel pipe, angle steel, i iron, channel-section steel or shaped steel beams etc.) are a kind of constructional materialss that can not burn, and it has the characteristics such as antidetonation, bending resistance.In actual applications, steel both can increase the weight bearing power of building relatively, also can satisfy the needs of architectural design aesthetic feeling moulding, the defective of also having avoided the constructional materialss such as concrete can not be crooked, to stretch, therefore steel have been subject to the favor of building trade, individual layer, multilayer, skyscraper, factory building, storehouse, waiting lounge, departure lounge etc. adopt steel all very general.But, steel as constructional materials in the defective that exists again some to be difficult to avoid aspect fire prevention, its mechanical performance, as yield point, tension and modulus of elasticity etc. all can Yin Wendu rising and sharply descend.Steel work will lose supporting capacity usually in 450～650 ℃ of temperature, very large deformation occurs, and causes steel column, girder steel bending, and result can not continue to use because of excessive deformation, and the fire endurance that does not generally add the steel work of protection is about 15 minutes.The length of this time is also relevant with the speed of member heat absorption.Make steel structure material overcome in actual applications the deficiency of fire prevention aspect, the processing of must preventing fires, its purpose is exactly the fire endurance of steel work to be brought up to the limit range of design specifications regulation.Prevent steel work intensification generation deformation slump rapidly in fire, its measure is diversified, key is to take distinct methods according to different situations, as adopt thermal insulation, refractory material to intercept the direct calcination steel work of flame, reduce the speed postponement steel work temperature rise of heat transmission, the time of weakened etc.
China national Department of Intellectual Property on February 11st, 2004 notice of authorization a patent No. be the patent documentation of ZL01129895.2, this disclosure of the invention a kind of steel structure fire-fighting method, it comprise make the refractory fibre composite fire-proof blanket, to need the fire-resistant pinning of welding on the fireproof steel structure body, to need the fireproof steel structure body carry out preservative treatment, on the steel structure body that carried out preservative treatment parcel refractory fibre composite fire-proof blanket, and be combined with pinning, the refractory fibre composite fire-proof blanket be fixed on the first-class step of steel structure body with self-locking gasket.Described refractory fibre composite fire-proof blanket adopts resistance to elevated temperatures good and alumina-silicate refractory fibre blanket and incombustible glass mat that coefficient of thermal conductivity is low to be composited.There is difficulty of construction in the method greatly and the high shortcoming of material cost, especially fire blanket self need to be supported by the steel work main body, cause thus fire blanket and steel work main body to fit very closely, thereby accelerated the temperature rise of steel work main body, be unfavorable for the fire prevention of steel work main body.
Also have some other measures, as coat fireproof paint on the steel work main body, the initial stage of Construction of Steel Structure fire protection requirement energy (mostly being the detection time of supervision department this moment) up to standard, after in a few years, fireproof paint is aging, loses the fireproof effect, when steel work just plays a role, fire proofing material had lost efficacy, thereby affected the application life of whole steel building, and again overhauling or spray can increase very large maintenance cost again.As the U.S. World Trade Organization mansion that collapses in " 911 " event, to be exactly that the fire proofing material of steel work is below standard cause collapsing in the short time to its main cause.Coat fireproof paint on the steel work main body, the defective such as have also simultaneously that cost is high, difficulty of construction is large, flameproof effect is permanent and outward appearance is ugly.
Except the fireproof requirement, also need to consider the heat-insulating property of steel work, the heat-blocking action when realizing in the winter time with summer with this.To reduce various limit weathers to the damaging influence of steel work, cause the distortion of steel work such as expanding with heat and contract with cold.
Based on the defective of above-mentioned prior art, the inventor designs a kind of novel insulated fire formed steel construction.
