Description
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of cellular web L tee section abnormity steel column.
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 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, the sectional dimension that usual needs are larger, if select 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, 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 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.
Utility model content
The purpose of this utility model is the stress performance improving existing steel flanged beam L tee section abnormity steel column and truss-like L tee section abnormity steel column, and the comprehensive cost of Control Engineering, a kind of cellular web L tee section abnormity steel column is provided.
The technical solution adopted in the utility model is: a kind of cellular web L tee 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 edge 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 L tee section abnormity steel column, described steel web one and steel web two are for establishing pertusate cellular web in centre, steel web one and steel web two are made up of the identical steel plate of the notched shape of two block edges respectively, this two block plate forms cellular 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.
The utility model 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 utility model 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 utility model 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 utility model: 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 utility model is reasonable, and mechanical property is good, economy attractive in appearance, remarkable benefit, and development prospect is wide;
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 is compared with steel flanged beam L tee 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;
Web of the present utility model according to different esthetic requirement, can design different hole shape, makes it attractive in appearance;
The utility model, from heavy and light, can alleviate dead load, thus reduces the pressure to ground, can reduce the cost of foundation;
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.
