Description

Corrugated steel web-compound section, concrete filled steel tube edge of a wing L shape post
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 L shape post.
Background technology
In the modernization construction of multi and tall steel building house, the advantage of special-shaped column structure is more and more remarkable, and status becomes increasingly conspicuous, and is subject to domestic and international academia and the common great attention of engineering personage in recent years, development rapidly, makes its application in engineering also more and more extensive.
In the Practical Project of multi and tall steel building house, its corner post adopts traditional flat web steel flanged beam L tee section abnormity steel column or truss-like L tee section abnormity steel column usually.In order to meet the requirement of bending stress performance, usually need larger sectional dimension, particularly web size.If select flat web steel flanged beam L tee section abnormity steel column, its web shear strength can be had more than needed a lot, but in order to ensure the local stability of web, meet the web ratio of height to thickness limit value of " Code for design of steel structures " defined, usually need again to increase its web thickness, this will cause increasing steel consumption, increase engineering cost, thus add engineering comprehensive cost; If select truss-like L tee section abnormity steel column, except its shear-carrying capacity, anti-seismic performance and overall stability are limited, its truss-like web member needs batten plate or lacing to be welded, construct relatively loaded down with trivial details, connect workload comparatively large, increase construction cost, thus also increase the comprehensive cost of engineering.And when moment of flexure effect is larger, the edge of a wing of above-mentioned two kinds of L tee sections abnormity steel column, may enter failure state too early, cause steel column to lose its drag very soon; Meanwhile, above two kinds of steel columns are pure steel structure, and its fire resistance is poor.
Utility model content
The purpose of this utility model is to improve the existing L tee section abnormity stress performance of 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 L shape post 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 L shape post, comprise the plain plate edge of a wing one, the plain plate edge of a wing two, the plain plate edge of a wing three, steel web one and steel web two, a side of described steel web two is connected with the edge of steel web one is vertical, form L tee section abnormity steel column, described steel web one and steel web two are 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 the steel plate edge of a wing one, the plain plate edge of a wing two, spot welding in the width on the plain plate edge of a wing three, the described plain plate edge of a wing one, the plain plate edge of a wing two, the plain plate edge of a wing three 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 a slice corrugated web by a slice corrugated web H type coupled column or two panels corrugated steel web welds with three concrete filled steel tube edges of a wing and combines.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 L tee 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, form equivalent longitudinal stiffener effect, the local stability of web can be improved, and improve the monolithic stability bearing capacity of steel column;
The utility model longitudinally need not set up longitudinal stiffener at component, labor and material saving, can reduce the integration engineering cost of engineering;
The utility model is compared with truss-like L tee section abnormity steel column, and simple structure, makes easy to process, quick, with low cost;
Compared with the utility model and truss-like L tee section abnormity steel column, its shear-carrying capacity is high, ductility and anti-seismic performance good, monolithic stability bearing capacity is superior;
Compared with the utility model and steel flanged beam L tee section abnormity steel column, when depth of section is equal, its steel using amount is few, from heavy and light, can saving steel, and reduce engineering cost;
The utility model, compared with steel flanged beam L tee section abnormity steel column, when cross-section steel materials are equal, increases section modulus, second moment of area and the radius of gyration, improves bending rigidity and stability bearing capacity that steel utilize usefulness and steel column;
