Description

The exposed syndeton of a kind of steel work suspension column
Technical field
The utility model relates to a kind of column foot connecting structure, particularly relates to the exposed syndeton of a kind of steel work suspension column.Belong to the structural steelwork field, the steel column that is applicable in high level and the large span architecture is connected with suspension column between the reinforced concrete foundation.
Background technology
The plurality of advantages such as high-strength light, plasticity good toughness, speed of application are fast because steel building has, good looking appearance, the application in design of building structures was more and more extensive in the last few years.The steel work suspension column is the bottom that is positioned at pillar in the steel building, the node that superstructure and basis, bottom effectively can be connected, play the effect of the Load Transfer such as the axle power of pillar lower end, bending and shearing to the basis, it is the principal element that determines structural stability and bearing capacity, it is passed to the basis with the structure upper load, is most important connected node in the structure.The stability of its coupling stiffness and structure is closely related, simultaneously structural internal force and displacement is produced material impact.According to the performance situation of suspension column under axial pressure and Moment, suspension column can be divided into rigidity, semi-rigid and flexible three types.
China is in industry and civilian construction structural steel design at present, the suspension column type of attachment has two kinds of exposed suspension column and flush type suspension columns usually, exposed suspension column is crab-bolt connection steel column and the basis with Transducers Embedded in Concrete, can be divided into real abdomen suspension column and separate suspension column, the multistory frame structure suspension column generally adopts real abdomen suspension column, should adopt real abdomen or separate suspension column according to crane tonnage size in the single-storey factory building, but exposed suspension column anti-seismic performance under the geology load action be not good enough.The flush type suspension column is that steel column is imbedded in reinforced concrete independent foundation or grade beam or the raft chip basis, and the transmission of suspension column internal force is the moment of flexure that produces by the concrete lateral pressure that contacts with the post edge of a wing, balance suspension column bending and shearing.
It is modal foot joint in the engineering reality that exposed steel construction rigidly fixes suspension column, the most general with the rectangular column sole that is subjected to Subjected To Compression, Bending, Shear, and the formula of introducing in the standard of energy reference and the handbook in the design also all is for this situation.But the continuous expansion along with the infrastructure scale, structure types also becomes increasingly complex, especially the extensive appearance of high-rise steel structure building, moment of flexure, moment of torsion, axle power that the suspension column position is born significantly increase, the problem that runs in the Practical Project is also more and more, and as in newly-built or addition, steel column foot generally adopts fixedly steel column of bar planting mode, suspension column internal force directly passes in original steel concrete by the bar planting crab-bolt, easily causes the destruction to original reinforced concrete structure.Built flooring of while or roofing reinforced concrete post capital place reinforcement ratio comparatively dense are so that boring bar planting difficult.In addition, the pre-buried quality of stone bolt also directly affects installation quality and the construction speed of superstructure.
In sum, the supporting capacity of steel work and applicability depend on the performance of suspension column to a great extent, connect in the engineering reasons such as embedding anchor bolts quality problems, steel concrete easily are damaged for solving present suspension column, need at present that a kind of structural integrity of invention is good, stressed evenly, the exposed syndeton of steel work suspension column of stone bolt accurate positioning badly.
