Cellular steel web-compound section, concrete filled steel tube edge of a wing cross section column
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of cellular steel web-compound section, concrete filled steel tube edge of a wing cross section column.
Background technology
In multi and tall steel building house, special-shaped column structure has the incomparable advantage of other structural systems, status in China's modernization construction becomes increasingly conspicuous, more and more be subject to the favor of people, be subject to the great attention of Chinese scholars and engineers and technicians in recent years, thus be used widely.
In the Practical Project of multi and tall steel building house, its center pillar adopts traditional steel flanged beam star section abnormity steel column or truss-like star section abnormity steel column usually.In order to meet the requirement of bending stress performance, the sectional dimension that usual needs are larger, if select steel flanged beam star 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, meets 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 star 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 star 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 the stress performance improving existing steel flanged beam web star section abnormity steel column and truss-like web member star section abnormity steel column, the comprehensive cost of unlikely remarkable its engineering of increase again, make it in engineering, be able to extensive use, a kind of cellular 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 cellular steel web-compound section, concrete filled steel tube edge of a wing cross section column, comprise the concrete filled steel tube edge of a wing one, the concrete filled steel tube edge of a wing two, the concrete filled steel tube edge of a wing three, the concrete filled steel tube edge of a wing four, steel web one, steel web two and steel web three, described steel web one, steel web two and steel web three are joined together to form dagger, four outer ends of this dagger respectively with the concrete filled steel tube edge of a wing one, the concrete filled steel tube edge of a wing two, the concrete filled steel tube edge of a wing three, the width mid point on the concrete filled steel tube edge of a wing four connects, form cross shaped column, steel web one, steel web two and steel web three are the middle cellular steel web being provided with web hole, steel web two and steel web three are made up of the identical steel plate of the notched shape of two block edges respectively, this two block plate forms cellular steel web by butt weld welding, steel web one is made up of the identical steel plate of the notched shape in edge, two pieces of sides and one block of notched steel plate in both sides of the edge, and this three block plate forms cellular steel web by butt weld welding.
As preferably, the hole form of described steel web one, steel web two and steel web three is circular, oval, square, rectangle, hexagon or octagon.
As preferably, the described concrete filled steel tube edge of a wing one, the concrete filled steel tube edge of a wing two, the concrete filled steel tube edge of a wing three and the concrete filled steel tube edge of a wing four are rectangular steel pipe or round steel pipe.
As preferably, the cross section of described cellular web star section abnormity steel column such as to comprise at limb and limb star section two class such as not.
The concrete generation type of the utility model post is: first cut by predetermined broken line or curve on web steel plate used, half-wave butt welding of staggering forms cellular steel web, then with the steel-pipe welding on the concrete filled steel tube edge of a wing, in the most backward steel pipe, fluid concrete combines.
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); " divergence ratio " (percent opening) in coupled column cross section increases, and depth of section increases, and its rigidity and the radius of gyration strengthen, and slenderness ratio can reduce, and stability bearing capacity is improved.But behind web holes hole, its shear behavior can be subject to certain impact.Therefore, in Practical Project, " divergence ratio " or percent opening should be controlled depending on actual loading situation; 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.
Essential characteristic of the present utility model: in comparatively economic mode, increases the depth of section of steel column, improves rigidity and the stability bearing capacity of steel column; Penetration concrete in the steel pipe of the edge of a wing, improves the local stability of steel pipe; 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;
The utility model is compared with truss-like star section abnormity steel column, and simple structure, makes easy to process, quick, with low cost;
Compared with the utility model and truss-like star 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 star 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 is compared with steel flanged beam star section abnormity steel column, when cross-section steel materials are equal, increase depth of section, section modulus, second moment of area and the radius of gyration, improve bending rigidity and stability bearing capacity that steel utilize usefulness and steel column;
