Effect.Especially in recent years, rapid in undergoing an unusual development for China's concrete filled steel tube, the research to concrete filled steel tube
Also more and more.
Conventional steel concrete column section is mostly circle, and the steel pipe at beam with column connected node needs to penetrate through, this be into
One of critical issue when row concrete filled steel tube engineering design.The validity of connecting node directly affect integrally-built rigidity,
Stability and bearing capacity also influence site operation difficulty and construction speed, and the steel pipe continuously penetrated through in addition is but also steel pipe
Vibrating for inner concrete becomes difficult, to influence construction quality.There is also steel using amounts for steel core concrete column in actual use
Larger, steel pipe needs to carry out the problems such as anti-corrosion fire prevention conserves.
Utility model content
To solve the above problems, the utility model provides a kind of steel core concrete column.
A kind of steel core concrete column provided by the utility model, including steel skeleton, bar frame and concrete；The reinforcing bar

It is formed by multiple reinforcing bars and stirrup and double-way opposed-pulling reinforcing bar, multiple reinforcing bars are longitudinally located in cylinder, the stirrup and described double
To drawing reinforcing bar longitudinally disposed along cylinder；Concreting in the steel skeleton outside leave a blank in region.
In one embodiment, the steel skeleton forms the structural system being closed in the cross section of cylinder.
In one embodiment, the quantity of the angle steel is 4.
In one embodiment, the angle steel is equal leg angle.
In one embodiment, the midpoint in the quadrangle of cylinder and four edges is arranged in the longitudinal reinforcement.
In one embodiment, longitudinal every 100mm one of stirrup of setting and double-way opposed-pulling reinforcing bar along cylinder.
In one embodiment, the concrete fills up on the outside of in the steel skeleton leave a blank region and vibration compacting.
A kind of steel core concrete column provided by the utility model includes the lattice being welded to form by equal leg angle and batten plate
Steel skeleton, it is longitudinally disposed to drawing reinforcing bar and multiple reinforcing bars and column body concrete along cylinder.The steel core concrete column is by lattice
Structure formula steel skeleton generates cuff effect of contraction to concrete, so that the concrete is in three dimension stress state, is unidirectionally pressurized with existing
Concrete column is compared, and bearing capacity improves 2 times or so under identical size, the feature that plasticity is good and anti-seismic performance is high.Simultaneously because
The cross section of steel core concrete column is rectangle, and there are certain spacing between batten plate on facade, this is with regard to effective solution beam column
The connectivity problem of node, but also the enhanced convenience of vibrating of inner concrete.Double-way opposed-pulling is set on the outside of lattice steel skeleton
Reinforcing bar reinforces the confined effect of core concrete, while outer concrete plays a protective role for steel skeleton, without applying fire prevention
And anticorrosive paint, and effectively solve fire prevention and the Anticorrosion of steel skeleton.Lattice steel skeleton in the steel core concrete column
Itself be stiffness load-bearing skeleton, play stiff skeleton in construction, welding job amount more than normal section steel skeleton be it is few,
Lighter weight is lifted, so as to simplify installation technology, improves working efficiency.

Wherein, 1 angle steel, 2 batten plates, 3 pairs of drawing reinforcing bars, 4 stirrups, 5 longitudinal reinforcements, 6 concrete.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of steel core concrete column make further it is detailed
It describes in detail bright.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that attached
Figure is all made of very simplified form and uses non-accurate ratio, only new conveniently, lucidly to aid in illustrating this practicality
The purpose of type embodiment.
Embodiment one
The present embodiment one provides a kind of steel core concrete column, and transversal plane structural schematic diagram is as shown in Figure 1.The steel pipe
Concrete column includes steel skeleton, bar frame and concrete.The steel skeleton includes four equal leg angles 1 and four batten plates 2, often
A batten plate 2 respectively welds angle steel 1 two-by-two, forms rectangle lattice steel skeleton.The steel skeleton is formed in the cross section of cylinder
The structural system of closure.Wherein, the length of side of the angle steel is 90mm, thickness 12mm；The batten plate 2 is cut by the steel plate of 8mm thickness
