The utility model discloses improved the atress performance of current lattice column, under the prerequisite that does not increase steel materials to comparatively economic mode, the cross-sectional height of increase steel column has improved the rigidity of steel column and has stabilized the bearing capacity.
Description
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to the battened steel column that a kind of cellular junction plate connects.
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 almost can not be substituted with effect.
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, building storey increases gradually, upper load increases, and steel column sectional dimension 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 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 needing to arrange tabula at this place, steel consumption and difficulty of construction can be increased, reducing speed of application, increasing the construction period, thus increasing the comprehensive cost of engineering further.
Utility model content
The purpose of this utility model is the stress performance improving existing lattice column, 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, the battened steel column that a kind of cellular junction plate connects is provided.
The technical solution adopted in the utility model is: the battened steel column that a kind of cellular junction plate connects, comprise steel limb part one, steel limb part two, steel junction plate one and steel junction plate two, described steel limb part one is connected with steel junction plate two respectively by steel junction plate one with the two ends of steel limb part two, form battened steel column, steel junction plate one and steel junction plate two are the cellular junction plate of central aperture, steel junction plate one and steel junction plate two 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, described steel limb part one and steel limb part two are channel-section steel, steel pipe, i iron or steel plate.
As preferably, the open-cellular form of described steel junction plate one and steel junction plate two is circular, oval, square, rectangle, hexagon or octagon.
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, make the stability of void, real axis fully close, 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 utility model replaced traditional lattice column with cellular steel plate as junction plate sews material, forms the battened 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 with two limb parts.
In this section form, welding performance is better, and the bearing capacity of its steel column is higher, and for this reason, the utility model 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.
Essential characteristic of the present utility model: 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 utility model 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 utility model 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 utility model 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 utility model 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 utility model can under identical load-bearing condition, and its drag performance is better than traditional lattice column.
The utility model have employed cellular steel plate, compared with box section, can save rolled steel dosage.
The utility model can provide critical component for new steel structure system development, has good conversion prospect.
The utility model has expanded the research and apply field of laced of battened compression member, has greatly enriched the content of steel work.
