Description
Technical field
The utility model relates to a kind of column foot connecting structure, particularly a kind of flush type stone bolt syndeton being combined to form by I-shaped steel column, suspension column backing plate, expansion backing plate, pedestal shear key and stone bolt.Belong to structural steelwork field, be applicable to steel column in high level and long span building and be connected with the suspension column between concrete foundation.
Background technology
Steel work refers to the form of structure that can bear and transmit load being formed by connecting by connector with steel plate and hot rolling, clod wash or weld type steel.The comprehensive advantages such as steel structure system has from heavy and light, batch production manufacture, quick for installation, short construction period, anti-seismic performance is good, gain quick return in investment, low in the pollution of the environment, compare with reinforced concrete structure, have more the unique advantage of development aspect " high, large, light " three.In the world, particularly developed country and area, steel work obtains rationally in building engineering field, application widely.Steel building has become the main flow of international modernization Urban Architecture development, and particularly, along with the lifting of structure elucidation and steel structure technology, this trend is more obvious.Suspension column is in steel building, to be positioned at pillar bottom, the structure that superstructure effectively can be connected with basis, bottom.Although it is less that suspension column structure accounts for the ratio of monolithic architecture, it is passed to basis by structure upper load, is the principal element that determines structural stability and bearing capacity, is most important connected node in structure.
China is in industry and civilian construction structural steel design at present, and suspension column type of attachment adopts two kinds of exposed suspension column and flush type suspension columns conventionally.Exposed suspension column is that the larger base plate of suspension column bottom and relative rigidity is welded to connect, and base plate is fixed by the crab-bolt being embedded in concrete foundation in advance.First the pressure that exposed suspension column structure transmits shaft pass to base plate through shaft, then by base plate, pressure is passed to concrete foundation.Exposed suspension column is assembling, and construction speed is relatively very fast, but the structure of base plate and crab-bolt system causes steel using amount larger, and plate complex structure, and manufacture and welding job amount are heavy.And exposed suspension column is by two bolt anchorings on basis, and rigidity is unlike flush type suspension column.
Flush type suspension column is that the length that steel column bottom is equivalent to about pillar depth of section twice is imbedded in the basement beam or grade beam concrete that rigidity is larger, around with steel concrete, strengthen, the special delivery of suspension column internal force is the moment of flexure that the concrete lateral pressure by contacting with the post edge of a wing produces, balance suspension column bending and shearing.The structure of flush type suspension column is more reasonable, be easy to installation in position, the build-in type of suspension column easily guarantees, and the more exposed suspension column of flush type suspension column rigidity is larger, good integrity, bearing capacity is large, and for the trend at present building span, requirement for height being improved day by day, the use of flush type suspension column is also more and more extensive.But in some cases,, when upper axis power is delivered to base plate, usually can cause concrete local failure under floor.In simultaneously steel column construction, usually occur lifting difficulty, the easy off normal in installation site, verticality are inadequate, and the problem such as backing plate floating and skew in concreting process affects the stressed and load-carrying properties of steel column.
In sum, the bearing capacity of steel work and applicability depend on the performance of suspension column to a great extent, for solving concrete destructible under flush type suspension column, backing plate floating and skew in concreting process, need that invention is a kind of can effectively control the I-shaped steel column flush type stone bolt syndeton that steel column skew, easy for installation, suspension column and basic switching performance are good at present badly.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, invent a kind of force path clear and definite, can effectively control steel column off normal, prevent that under backing plate, concrete office crushes bad, avoid the floating of backing plate in concreting process and the flush type stone bolt syndeton of skew, can be used as I-shaped steel column and concrete foundation joint pin leg structure and use.
