Description

Novel cold-formed rectangular tube-steel column assembling suspension column

Technical field

The utility model relates to a kind of suspension column fastening devices of steel pipe column.

Background technology

Studies show that, along with China's economic development and to the understanding of steel work advance, urbanization process in conjunction with China, and with reference to the national conditions of China, realize that the steel house industrialization will be the developing direction of Future in China dwelling house, greatly developing many high-rise steel structure dwelling house, is tally with the national condition one housing industrialization thinking preferably.So in recent years, steel house is advocated in country's beginning energetically, and the large-scale application of steel house has become possibility.

The industrialization that wants to develop many high-rise steel structure dwelling house and realize steel house, the work that need do also has a lot, realizes that wherein the steel house standardization is exactly one of basic work.In the steel house standardization, the standardization of steel structure system and structural element thereof will be at first to need the work done.For many high-rise steel structure dwelling house, no matter adopt which kind of structural system, pillar all is one of them topmost member, studies show that through some, cold-formed rectangular tube-steel column and clod wash rectangular steel-tube concrete column will be because stable performance, bearing capacity height, advantage such as lateral deformation stiffness is big, displacement deformation is little, shock stability is good will be one of optimal selections of the pillar in many high-rise steel structure dwelling house.

In the steel architectural structure system, suspension column is steel work middle and upper part structure and the important component that the basis is connected, and is a key factor of its total system supporting capacity of decision.Existing suspension column can be divided into hinged column base substantially and rigidly connect suspension column two big classes by structure internal force, and wherein hinged column base only can transmit horizontal force and vertical force, and the rigidity suspension column can also transmit moment of flexure except transmitting horizontal force and vertical force.

For many high-rise steel structure building, because the suspension column counter-force is bigger, so adopt rigidity suspension column fastening devices during design mostly.The fixing form of rigidity suspension column is divided into three kinds of exposed suspension columns, flush type suspension column, outer-enwraped type suspension column usually, base plate was both big and thick because the exposed suspension column of employing not only can make, the consumption great deal of steel, and be difficult to guarantee being completely fixed of suspension column, be the better form of the fixed suspension column of many high-rise steel structure so adopt flush type suspension column and outer-enwraped type suspension column.

The flush type suspension column is that steel pipe column is embedded in the concrete foundation beam with certain depth, the steel pipe column surface of inlet part is welded with peg, the axial compression of post can be passed to concrete by the suspension column base plate, the axial tension of post can be passed to concrete to concrete pressure-bearing effect by suspension column base plate extension, or pass to the basis by crab-bolt, flush type suspension column loading characteristic has determined the flush type suspension column to have the degree of rigidly connecting height, the advantage that anti-seismic performance is good, but also caused simultaneously the shortcomings such as complex structure of suspension column.

The outer-enwraped type suspension column is that the steel pipe column base plate flushes with the external wrapping concrete bottom, and external wrapping concrete is furnished with main muscle and stirrup, and the top stirrup is wanted centralized configuration, and the outer packet portion of steel pipe column will be provided with peg.General steel pipe column power transmission is by bearing capacity and two kinds of mechanism of holdfast, and the suspension column moment of flexure is born by external wrapping concrete, and the axle power of pillar it is generally acknowledged by the steel pipe column base plate and directly pass to the basis, axial tension can by base plate stretch out the edge and crab-bolt is passed to the basis.The make of outer-enwraped type suspension column and loading characteristic have determined the outer-enwraped type suspension column to have simple structure, do not influence the advantage that reinforcement foundation is arranged, but its power transmission mechanism more complicated, existing counting system is not strict.

In addition, no matter present stage is flush type suspension column or outer-enwraped type suspension column, pillar in the construction adopts the job practices of lifting more, in hoisting process, the location of pillar is the problem of a special trouble, simultaneously pillar and base plate are adopted the method that is welded to connect basically, higher requirement is arranged for weldquality.Simultaneously, in the suspension column design, the content that relates to suspension column owing to standard is less, stipulates also detailed inadequately, and because the stress performance of steel pipe suspension column is not fully aware of, actual in the process of carrying out the suspension column design, artificial the suspension column model has been done some supposition, the model of design is also relatively simplified, this just makes the suspension column design vary with each individual, and in order to guarantee safety, the design of suspension column is relatively conservative, has also caused waste to a certain extent.

In sum, for many high-rise steel structure buildings, how on the basis of satisfying various combination properties such as suspension column bearing capacity, anti-seismic performance, simultaneously can make both simple structures of suspension column, convenient construction again, also meeting the basic demand of standardization, industrialization, is a significant urgent problem again.
