Description
Technical field
The present invention relates to a kind of new builing structure technical field, be specifically related to a kind of cellular web star section abnormity steel 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.
Summary of the invention
The object of the invention is to 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 web star section abnormity steel column is provided.
The technical solution used in the present invention is: a kind of cellular web star section abnormity steel column, comprise the rectangular steel pipe edge of a wing one, the rectangular steel pipe edge of a wing two, the rectangular steel pipe edge of a wing three, the rectangular steel pipe 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 rectangular steel pipe edge of a wing one, the rectangular steel pipe edge of a wing two, the rectangular steel pipe edge of a wing three, the width mid point on the rectangular steel pipe edge of a wing four connects, form the special-shaped steel column of star section, 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 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 steel column of the present invention is: first cut by predetermined broken line or curve on web steel plate used, and the half-wave butt welding and form cellular web of staggering respectively, be then welded with frange plate.
Steel column of the present invention can also be welded by a slice cellular web H shaped steel and two panels cellular web T-steel or four cellular web T-steels are welded.Specifically first to cut by predetermined broken line or curve on the web of H profile steel and T-steel respectively when being formed, and the half-wave butt welding and form cellular web H shaped steel and cellular web T-steel respectively of staggering respectively, then three is welded formation.
In section constitution, welding process and welding quality can directly affect steel column performance, and for this reason, the present invention needs to ensure good welding process (can adopt welding technique); " divergence ratio " (percent opening) of steel column web 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.
Essential characteristic of the present invention: in comparatively economic mode, increases the depth of section of steel column, improves rigidity and the stability bearing capacity of steel column; Section constitution is reasonable, and mechanical property is good; Simple structure, makes easy to process, quick, labor and material saving, will reduce engineering cost.
Beneficial effect: section constitution of the present invention is reasonable, and mechanical property is good, economy attractive in appearance, remarkable benefit, and development prospect is wide;
The present invention is compared with truss-like star section abnormity steel column, and simple structure, makes easy to process, quick, with low cost;
Compared with the present invention 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 present invention 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 present invention, compared with steel flanged beam star section abnormity steel column, when cross-section steel materials are equal, increases depth of section, 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;
Steel column of the present invention and employing all steel form, compared with ordinary reinforced concrete hetermorphiscal column, from heavy and light, bearing capacity is high, ductility good, anti-seismic performance is excellent;
Web of the present invention according to different esthetic requirement, can design different hole shape, makes it attractive in appearance;
