Description
Technical field
The utility model relates to a kind of new builing structure technical field, is specifically related to a kind of cellular junction steel plate-three limb concrete filled steel tube coupled column.
Background technology
Along with expanding economy, the requirement of people to the form of structure of house, public building also improves gradually, for traditional concrete, steel work has saving steel, the advantages such as reduction cost, short construction period, anti-seismic performance are good, are subject to the favor of people, thus are 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 public building, heavy_weight factory, 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.In addition, for the press-bending post that moment of flexure is larger, its steel limb part may lose its bearing capacity in advance, makes it not meet requirement of engineering.Now, the mode as how comparatively economic improves its single limb bearing capacity, and reduces the shear strain of its imaginary axis, is the key point solving this problem.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cellular junction steel plate-three limb concrete filled steel tube coupled column.
The technical solution adopted in the utility model is: a kind of cellular junction steel plate-three limb concrete filled steel tube coupled column, comprise concrete filled steel tube limb part one, concrete filled steel tube limb part two, concrete filled steel tube limb part three, steel junction plate one, steel junction plate two and steel junction plate three, described concrete filled steel tube limb part one, between two by steel junction plate one between concrete filled steel tube limb part two and concrete filled steel tube limb part three, steel junction plate two and steel junction plate three are interconnected, Formation cross-section is leg-of-mutton three limb round steel tubing strings, steel junction plate one, steel junction plate two and steel junction plate three are the cellular junction plate of central aperture, steel junction plate one, steel junction plate two and steel junction plate three 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 open-cellular form of described steel junction plate one, steel junction plate two and steel junction plate three is circular, oval, square, rectangle, hexagon or octagon.
For laced of battened compression member, limb part mainly bears axle power and moment of flexure, and the material of sewing connecting two limbs mainly resists horizontal shear.Therefore, mode as how comparatively economic improves its single limb bearing capacity, and reduce the shear strain of its 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 steel column with cellular steel plate as junction plate sews material, the steel limb part concrete filled steel tube of traditional lattice three limb steel column is replaced, and both welding are formed a kind of cellular junction steel plate-three limb concrete filled steel tube coupled column.Concrete generation type is: first cut by predetermined broken line or curve on steel plate, preset distance butt welding of staggering forms cellular junction plate, and then with the steel-pipe welding of concrete filled steel tube list limb, in the most backward steel pipe, fluid concrete combines.
In this section constitution, welding performance is better, and the bearing capacity of its post is higher, and for this reason, the utility model needs to ensure good welding process (can adopt welding technique); " divergence ratio " (percent opening) in coupled 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; Single limb is formed by steel pipe and Combined concrete, and due to the limited space in steel pipe, therefore during fluid concrete, inconvenience is vibrated, therefore should select self-compacting concrete.
Essential characteristic of the present utility model: in comparatively economic mode, improve its single limb bearing capacity, 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 coupled 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.
Coupled column of the present utility model, owing to having poured into a mould concrete in single limb steel pipe, the concrete of steel duct can prevent steel pipe generation cripling effectively, and the effect of contraction of steel pipe to its inner concrete makes concrete be in three dimension stress state, improves concrete compressive strength; Both play a role jointly, and the ductile performance of component is obviously improved, and energy dissipation capacity improves, and has superior anti-seismic performance.
The utility model, owing to being filled with concrete in steel pipe, can absorbing a large amount of heat energy, add the fire resistance period of pillar, be conducive to the fire-resistance of steel pipe, fire prevention and Anticorrosion.
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 is under identical load-bearing condition, and its drag performance is better than corresponding traditional lattice steel column.
The utility model can provide critical component for new steel structure public building system development, has good conversion prospect.
The utility model has expanded the research and apply field of encased structures, has greatly enriched steel-concrete combined structure content.
