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.Certainly, the steel box column selecting cellular web can also be considered.But in Practical Project, in order to the shear resistance of unlikely too much weakening steel column, " divergence ratio " in the steel box column cross section of cellular web can be subject to certain restrictions.In the case, particularly for the larger press-bending post of moment of flexure, its bearing capacity may be lost in advance in its edge of a wing, makes it not meet requirement of engineering.Now, the mode as how comparatively economic improves its single limb bearing capacity, is the key point solving this problem.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of cellular junction steel plate-bis-limb steel pipe concrete combination column is provided.
The technical solution used in the present invention is: a kind of cellular junction steel plate-bis-limb steel pipe concrete combination column, comprise concrete filled steel tube limb part one, concrete filled steel tube limb part two, steel junction plate one and steel junction plate two, described concrete filled steel tube limb part one is connected with steel junction plate two respectively by steel junction plate one with the two ends of concrete filled steel tube 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, 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, two limb parts mainly bear 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 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 present invention replaced traditional lattice steel column with cellular steel plate as junction plate sews material, is replaced by the steel limb part concrete filled steel tube of traditional lattice steel column, and both welding are formed a kind of cellular junction steel plate-bis-limb steel pipe concrete combination column.Concrete generation type is: first cut by predetermined broken line or curve on web steel plate used, stagger half ripple, makes crest to crest, forms cellular junction plate with butt weld welding, 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 form, welding performance is better, and the bearing capacity of its 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 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.
