Description

The four limbs steel column that cellular junction plate connects
Technical field
The present invention relates to a kind of new builing structure technical field, be specifically related to the four limbs steel column that a kind of cellular junction plate connects.
Background technology
For traditional concrete structure, steel work has the advantages such as deadweight is light, short construction period, anti-seismic performance are good, is more and more subject to the favor of people, thus is widely used.
Steel column can be divided into steel flanged beam and the large class of lattice two by its section form.Comparatively speaking, solid-webbed column simple structure, is connected also more for convenience with other components.But, along with the development of multi-rise building, longspan structure, heavy_weight factory, when building storey increases gradually, when upper load increases, steel column sectional dimension must be caused to increase, thus increase steel consumption, improve 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 the shear strain of the imaginary axis is comparatively large, will cause certain additional flexibility, will reduce its service behaviour; 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; And, when shaft somewhere receives the masterpiece used time in larger level set, for avoiding post limb by curved, also need to arrange tabula at this place, steel consumption and difficulty of construction can be increased again, reduce speed of application, increase the construction period, thus increase the comprehensive cost of engineering further.
Summary of the invention
The object of the invention is to the stress performance improving existing lattice column, in comparatively economic mode, improve rigidity and the stability bearing capacity of steel column, the four limbs steel column that a kind of cellular junction plate connects is provided.
The technical solution used in the present invention is: the four limbs steel column that a kind of cellular junction plate connects, comprise steel pipe limb part one, steel pipe limb part two, steel pipe limb part three, steel pipe limb part four, steel junction plate one, steel junction plate two, steel junction plate three and steel junction plate four, described steel pipe limb part one, steel pipe limb part two, steel pipe limb part three and steel pipe limb part four are by steel junction plate one, steel junction plate two, steel junction plate three and steel junction plate four link together, form rectangular section column, described steel junction plate one, steel junction plate two, steel junction plate three and steel junction plate four are the cellular junction plate of central aperture, steel junction plate one, steel junction plate two, steel junction plate three and steel junction plate four are made up of the identical steel plate of the notched shape of two block edges respectively, this two block plate forms cellular junction plate by butt weld welding.
As preferably, the hole form of described steel junction plate one, steel junction plate two, steel junction plate three and steel junction plate four is circular, oval, square, rectangle, hexagon or octagon.
As preferably, described steel pipe limb part one, steel pipe limb part two, steel pipe limb part three, steel pipe limb part four are rectangular steel pipe or round steel pipe.
For laced of battened compression member, the material of the sewing shear behavior of the imaginary axis being mainly subject to connecting to single limb affects.Therefore, how to reduce its shear strain to the imaginary axis, improve its shear-carrying capacity, improve its stress performance, the material of two major axes orientations can be not fully exerted, to reduce rolled steel dosage, reduce the comprehensive cost of engineering, become the focus that people pay close attention to.To this, what the present invention replaced traditional lattice column with cellular steel plate as junction plate sews material, forms the four limbs steel column that a kind of cellular junction plate connects.Concrete generation type is: first cut by predetermined broken line or curve on steel plate, stagger half ripple, make crest to crest, form (or directly being formed by required steel plate punching) cellular junction plate with butt weld welding, be then welded between two with limb part.
In this section constitution, welding performance is better, and the bearing capacity of its steel column is higher, and for this reason, the present invention needs to ensure good welding process; In addition, " 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.
Jointing mode of the present invention: cellular junction steel plate overlaps with single limb or docks (cellular junction steel plate being placed in single limb front to be just connected its centre of form place).
Essential characteristic of the present invention: in comparatively economic mode, improve the service behaviour of traditional lattice column imaginary axis, improve its rigidity and stability bearing capacity, reduces the performance difference of traditional lattice column void, real axis.
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.
The present invention compared with traditional lattice column, improves it to the rigidity of the imaginary axis and shear-carrying capacity, reduces its shear strain, thus improve its service behaviour, make it stressedly more be tending towards reasonable after replacing with cellular steel plate sew material as junction plate.
After the present invention sews material with cellular steel plate as junction plate replacement, compared with traditional lattice column, its simple structure, reduce difficulty of construction, make easy to process, reduce construction workload, accelerate speed of application, thus shorten the duration, the comprehensive cost of engineering is reduced.
After the present invention sews material with cellular steel plate as junction plate replacement, compared with traditional lattice column, the collaborative work ability of its limb part and junction plate is stronger, and resistance to overturning is better, thus improves the anti-seismic performance of structure.
The present invention can under identical load-bearing condition, and its drag performance is better than traditional lattice column.
Present invention employs cellular steel plate, compared with box section, can rolled steel dosage be saved.
The present invention can provide critical component for new steel structure public building system development, has good conversion prospect.
The present invention has expanded the research and apply field of laced of battened compression member, has greatly enriched the content of steel work.
