Description

Built-in X-type is to drawing steel plate type welding rectangular steel-tube concrete column and construction method
Technical field
The present invention relates to the building element and its construction method in building structure, specifically refers to a kind of built-in X-type to drawing steel Board-like welding rectangular steel-tube concrete column and its construction method.
Background technology
Concrete filled steel tube refers to the fill concrete in steel pipe, and steel pipe and its core concrete bear external load effect jointly Structural elements.Compared with reinforced column, in steel core concrete column, steel pipe makes to mix to the effect of contraction of its inner concrete Solidifying soil is in three dimension stress state, improves the compression strength of concrete, and the concrete of steel duct can be effectively prevented again There is local buckling in steel pipe, the interaction between steel pipe and concrete makes the destruction of steel duct concrete be turned by brittle break It is changed into plastic failure, the ductile performance of component is obviously improved, and energy dissipation capacity is greatly improved, with good anti-seismic performance.Meanwhile, Template is not needed during Construction of Steel Pipe Concrete Column, formwork, the material of form removal and labour cost is saved, the time is also saved.Cause This, steel core concrete column is obtained in high-rise and super-high building structure, large-scale heavy duty industrial premises and long-span bridges It is widely applied.
