Abstract
The invention discloses a honeycomb-shaped web H-shaped steel column. The honeycomb-shaped web H-shaped steel column comprises a first steel flange, a second steel flange and a steel web; the steel web is arranged between the first steel flange and the second steel flange; the steel web is a honeycomb-shaped web of which the middle is provided with an opening; the steel web consists of two steel plates of which the edges are provided with notches and the shapes are the same; the two steel plates are welded by a butt-jointed seam to form the honeycomb-shaped web. According to the invention, on the premise of not increasing the used steel, the cross height of the steel column is increased in an economic manner and rigidity and stable carrying capacity of the steel column are improved.
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 H steel column.
Background technology
In recent years, the output of domestic steel and steel, kind, specification significantly promote, and the design of steel work, making, installation level have had especially and increase substantially, and steel work obtains extra normal development at home.
Reinforced concrete post, owing to existing from the shortcoming such as great, crack resistance is poor, makes it be difficult to meet the requirement such as bearing capacity and durability, thus limits its scope of application; And steel column have intensity high, from heavy and light, the feature such as anti-seismic performance is good, deformability is strong, short construction period, good and abundant architectural art representation ability, be subject to the generally favor of architects.In the practice for many years of conventional metallurgical industrial premises, high level and Super High and longspan structure, the outstanding advantage of steel column is alternative hardly with effect.
Steel column, by the composition form in its cross section, can be divided into steel flanged beam and the large class of lattice two.Comparatively speaking, solid-webbed column simple structure, is connected also more for convenience with other components.Wherein, particularly H profile steel, it is more reasonable that its section area distributes optimization, the ratio of strength to weight more, has the advantage that modulus of section is large, lightweight, save steel, building structure can be made to alleviate 30-40%; In addition, because each position of H profile steel all becomes component with orthogonal arrangement assembling combination, can save welding, riveting work amount reaches 25%, therefore it all has that bending resistance is strong, the advantages such as simple, cost-saving and lightweight construction of constructing in all directions, is widely used.But along with the development of multi-rise building, longspan structure, heavy_weight factory, building storey increases gradually, upper load increases, and H profile steel column cross-section size must be caused to increase, thus increases steel consumption, improves the comprehensive cost of engineering.Now, in order to saving steel, conventional method is, selects laced of battened compression member.But, laced of battened compression member cross section is combined through sewing material connection by single limb, make construction relatively loaded down with trivial details, connect workload bigger than normal, and its Beams Oblique Section Carrying Capacity and anti-seismic performance limited, particularly stability difference that is empty, real axis is comparatively large, causes its material not give full play to, also will inevitably increase the comprehensive cost of engineering.
Summary of the invention
The object of the invention is under the prerequisite not increasing steel materials, in comparatively economic mode, to increase the depth of section of steel column, improve rigidity and the stability bearing capacity of steel column, a kind of cellular web H steel column is provided.
The technical solution used in the present invention is: a kind of cellular web H steel column, comprise the steel edge of a wing one, the steel edge of a wing two and steel web, described steel web is arranged between the steel edge of a wing one and the steel edge of a wing two, steel web is the cellular web of central aperture, steel web is made up of the identical steel plate of the notched shape of two block edges, and this two block plate forms cellular web by butt weld welding.
As preferably, the described steel edge of a wing one and the steel edge of a wing two are steel plate or Flat steel pipe or channel-section steel or i iron.
As preferably, the open-cellular form of described steel web is circular, oval, square, rectangle, hexagon or octagon.
For the steel column in H-shaped cross section, usually to bear pressure, mostly be axial compression, bending component in practical engineering application, flexural strength and rigidity are the key factors affecting its bearing capacity.Therefore, under the prerequisite not increasing steel using amount, how to reach out for larger flexural strength and rigidity, thus obtain higher stability bearing capacity, become the focus that people pay close attention to.To this, cross section of the present invention building form is: first cut by predetermined broken line or curve on steel plate, stagger half ripple, makes crest to crest, forms cellular web, be then welded with frange plate with butt weld welding.In this section form, welding performance is better, and the bearing capacity of H profile steel post is higher, and for this reason, the present invention needs to ensure good welding process (can adopt welding technique); " divergence ratio " (percent opening) in steel 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 present invention can also be welded after its web cuts along a certain regular curve or broken line again by H profile steel, or directly forms in the web punching of large H-shaped steel.
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.
Beneficial effect: it is reasonable that steel column of the present invention has section constitution, the features such as from heavy and light, bending rigidity is large, and bearing capacity is high, attractive in appearance and remarkable in economical benefits, development prospect is wide.
H profile steel post of the present invention, compared with former H profile steel post, increases moment of inertia and the radius of gyration in cross section, improves rigidity and the stability bearing capacity of steel column.
H profile steel post of the present invention, compared with former H profile steel post, adds depth of section, increases section modulus, improves the flexural strength of H profile steel post.
The present invention is due to web holes hole, and the tension rib being convenient to lay in infilled wall directly penetrates, and makes wall, beam, post become overall, thus improves the anti-seismic performance of structure.
The present invention, due to web holes hole, saves rolled steel dosage and paint, freight greatly, thus reduces the comprehensive cost of engineering, have very strong economic results in society.
The present invention is owing to can open difform hole according to designing requirement, and compared with traditional real abdomen H profile steel post, profile is more attractive in appearance.
The present invention is not affecting under structure function and service condition, alleviates deck deadweight, thus reduces the cost of ground, foundation.
The present invention solves steel structure fireproofing, Anticorrosion preferably when not increasing cost.
The present invention is compared with lattice post, and its building unit simple structure, makes easy to process, can reduce making processing charges, reduces engineering comprehensive cost.
The present invention can provide critical component for new steel structure system development, has good conversion prospect.
