Abstract

The invention discloses a double-steel-column combined column foot structure and a construction method thereof. The double-steel-column combined column foot structure comprises a bottom plate, a first steel column, a second steel column and a connecting plate, wherein the first steel column and the second steel column are arranged on the bottom plate in a spaced mode, an expansion joint is formed between the first steel column and the second steel column, the connecting plate is connected to the ends, close to the bottom plate, of the first steel column and the second steel column, and the connecting plate is positioned in the expansion joint. By adopting the scheme, when the first steel column and the second steel column are subjected to bending moment or the shearing force action in the same direction, the stress of the column foot bottom plate and a column foot anchor bolt can be reduced by utilizing the rigidity superposition effect of the first steel column and the second steel column, so that the situation that the column foot bottom plate and the column foot anchor bolt are possibly broken due to stress concentration can be avoided; and when the first steel column and the second steel column are subjected to bending moment or the shearing force action in opposite directions, the connecting plate can reduce force borne by the first steel column and the second steel column, and the safety of the first steel column and the second steel column is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel column base structures, in particular to a double steel column combined column base structure and a construction method thereof. Background technique [0002] The expansion joints of building structures are often designed as double columns, and the expansion joints between the double columns are generally about 200mm. According to this size, the column feet of the double columns cannot be independent, and it needs to be designed as a double column joint column foot. In the related art, the double-column combined column base is mainly through welding the steel column directly to the base plate of the column base, and the columns above the base plate of the column base are independent of each other. This method cannot achieve the joint force of the two columns, and cannot take advantage of the superposition of the stiffness of the two columns. Contents of the invention [0003] The embodiment of th...
