Description

Cellular web T section abnormity steel column
Technical field
The present invention relates to a kind of new builing structure technical field, be specifically related to a kind of cellular web T section abnormity steel column.
Background technology
In housing construction, special-shaped column structure has the incomparable advantage of other structural systems, and the parent being more and more subject to people looks at, and receives the great attention of Chinese scholars and engineering staff in recent years, thus obtains wider application.
But, in many high residential buildings, steel concrete deformed pile structure, due to be subject to column section limb long length depth ratio restriction and be difficult to meet requirement for bearing capacity, node region reinforcing bar is crowded, anti-seismic performance is undesirable and be difficult to process etc. problems, the advantage of hetermorphiscal column cannot be embodied comprehensively, thus limit its range of application, be difficult to promote.In order to overcome these deficiencies of shaped rc columns, there has been proposed all steel hetermorphiscal column.
In the Practical Project of multi and tall steel building house, its side column adopts traditional steel flanged beam T section abnormity steel column or truss-like T 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 T 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 T 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 improve traditional steel flanged beam T section abnormity steel column or the truss-like T section abnormity stress performance of steel column and the comprehensive cost of unlikely remarkable its engineering of increase, special-shaped column structure is more widely used in many high residential buildings, a kind of cellular web T section abnormity steel column is provided.
The technical solution used in the present invention is: a kind of cellular web T section abnormity steel column, 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, steel web two and hole, a side of described steel web two is connected with the middle part of steel web one is vertical, another side of steel web two, two sides of steel web one respectively with the plain plate edge of a wing one, the plain plate edge of a wing two, the plain plate edge of a wing three links together, form T section abnormity steel column, described steel web one and steel web two are for establishing pertusate cellular web in centre, steel web two is made up of the identical steel plate of the notched shape of two block edges, 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 is circular, oval, square, rectangle, hexagon or octagon.
As preferably, described cellular web T section abnormity steel column such as to comprise at limb and limb T section two class such as not.
The present invention is by the constituted mode of the steel plate edge of a wing and cellular steel web: 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.
The present invention can also be welded by cellular web H shaped steel and cellular web T-steel: first cut by predetermined broken line or curve on the web of H profile steel and T-steel respectively, and the half-wave butt welding and form cellular web H shaped steel and cellular web T-steel respectively of staggering respectively, then both are 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 L tee section abnormity steel column, and simple structure, makes easy to process, quick, with low cost;
Compared with the present invention 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 present invention 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 present invention, compared with steel flanged beam L tee 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;
The present invention, from heavy and light, can alleviate dead load, thus reduces the pressure to ground, can reduce the cost of foundation;
The present invention has expanded the research and apply field of steel column, has greatly enriched steel work content.
The present invention can provide novel critical component for the exploitation of new steel structure dwelling house system, has good conversion prospect.
