Description
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of corrugated steel web-compound section, concrete filled steel tube edge of a wing cross section column.
Background technology
Multi and tall steel building, the status in China's modernization construction becomes increasingly conspicuous, and the parent being more and more subject to people looks at, and is subject to the great attention of Chinese scholars and engineers and technicians in recent years, thus is used widely.
In the Practical Project of multi and tall steel building, particularly in the transition zone engineering connecting lower rebar concrete basement and steel superstructure, the flat web star section steel column that usual employing is traditional, and its sectional dimension is usually very large, particularly web size.In order to ensure the local stability of web, meeting the web ratio of height to thickness limit value of " Code for design of steel structures " defined, usually need increase its web thickness, this will cause increasing steel consumption, increase construction cost, thus increase the comprehensive cost of engineering.Still more, when moment of flexure effect is larger, its steel column edge of a wing pressure is excessive, may enter failure state too early, causes steel column to lose its drag very soon; Meanwhile, the fire resistance of pure steel structure is relatively poor.
Utility model content
The purpose of this utility model is stress performance in order to improve existing flat web star section steel column and fire resistance, the comprehensive cost of unlikely remarkable its engineering of increase again, make it in engineering, be able to extensive use, a kind of corrugated steel web-compound section, concrete filled steel tube edge of a wing cross section column is provided.
The technical solution adopted in the utility model is: a kind of corrugated steel web-compound section, concrete filled steel tube edge of a wing cross section column, comprise three steel webs and four edges of a wing, described three steel webs are joined together to form dagger, this dagger and four edges of a wing are connected to form cross shaped column, described steel web is corrugated steel web, corrugated steel column web form is shaped form, fold-line-shaped or trapezoidal, the corrugated limit of corrugated steel web in periodically repetition is perpendicular to component length direction, corrugated steel web non-corrugated limit respectively with spot welding in the width on four edges of a wing, the described edge of a wing is the concrete filled steel tube edge of a wing, the concrete filled steel tube edge of a wing comprises the concrete of steel pipe and inside thereof, concrete is self-compacting concrete.
Cross section of the present utility model is combined by corrugated steel web and the concrete filled steel tube edge of a wing.Concrete generation type is: the steel-pipe welding on corrugated steel web and the concrete filled steel tube edge of a wing, in the most backward steel pipe, fluid concrete combines.The essential structure of described coupled column: can be welded with the T-shaped coupled column of two panels corrugated web by a slice corrugated web H type coupled column or four T-shaped coupled columns of corrugated web are welded or three corrugated steel webs weld with four concrete filled steel tube edges of a wing and combine.When described corrugated steel web and the concrete filled steel tube edge of a wing are assembled into corrugated web L tee section coupled column, the tie point on its corrugated steel web and the concrete filled steel tube edge of a wing should be positioned at the width mid point on the concrete filled steel tube edge of a wing.In section constitution, welding process and welding quality can directly affect steel column performance, and for this reason, the utility model needs to ensure good welding process (can adopt welding technique).The edge of a wing is formed by steel pipe and Combined concrete, and due to the limited space in steel pipe, therefore during fluid concrete, inconvenience is vibrated, therefore should select self-compacting concrete.
Corrugated web arrangement of the present utility model: web is in the corrugated limit of periodically repeating perpendicular to component length direction, and web non-corrugated limit is welded with the concrete filled steel tube edge of a wing.Essential characteristic of the present utility model: in comparatively economic mode, improves the stress performance of existing star section abnormity steel column.The utility model put mode corrugated web can play equivalent longitudinal stiffener effect, the local stability of web and the rigidity of steel column and stability bearing capacity can be improved; Penetration concrete in the steel pipe of the edge of a wing, improves local stability and the refractory ability of steel pipe.Therefore, the utility model section constitution is reasonable, and mechanical property is good; Fire-resistant, antiseptic property good; Simple structure, make easy to process, quick, labor and material saving, engineering cost is low.
Beneficial effect: section constitution of the present utility model is reasonable, and mechanical property is good, economy attractive in appearance, remarkable benefit, and refractoriness is good, and development prospect is wide;
Web of the present utility model adopt put the corrugated web of mode, equivalent longitudinal stiffener effect can be played, the local stability of web and the monolithic stability bearing capacity of post can be improved;
Web of the present utility model adopt put the corrugated web of mode, longitudinally need not set up longitudinal stiffener at component, labor and material saving, the integration engineering cost of engineering can be reduced;
The utility model corrugated web can break through the ratio of height to thickness restriction of Code for design of steel structures defined, can reduce web thickness, saving steel, reducing engineering comprehensive cost when not reducing bearing capacity;
The edge of a wing of the present utility model adopts the concrete filled steel tube edge of a wing, and bearing capacity is high, and ductility is good, and anti-seismic performance is excellent, be conducive to fire-resistance and fire prevention, and corrosion resistance is high.
The utility model adopts steel-concrete combined structure form, and therefore bearing capacity is high, ductility good, anti-seismic performance is excellent;
The utility model, from heavy and light, can alleviate dead load, thus reduces the pressure to ground, can reduce the cost of foundation;
The edge of a wing of the present utility model steel pipe concrete filled, enhances the fire resistance of coupled column;
The concrete filled steel tube that the edge of a wing of the present utility model adopts institute to put mode combines the edge of a wing, improves edge of a wing local stability, thus improves the stability of whole coupled column;
The utility model is a kind of Novel special-shaped post being specially adapted to housing building of steel-structure, has expanded the research and apply field of steel column, has greatly enriched the content of steel structure column.
The utility model can provide novel critical component for the exploitation of new steel structure dwelling house system, has good conversion prospect.
