Double-steel-column combined column foot structure and construction method thereof
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.
本发明公开了一种双钢柱联合柱脚结构及其施工方法。其中，双钢柱联合柱脚结构包括底板、第一钢柱、第二钢柱和连接板，所述第一钢柱和所述第二钢柱间隔设置在底板上并在两者之间形成伸缩缝，所述连接板连接于所述第一钢柱以及所述第二钢柱的靠近所述底板的一端，且所述连接板位于所述伸缩缝内。采用本方案，当第一钢柱和第二钢柱受到同方向的弯矩或剪力作用时，可以利用第一钢柱和第二钢柱的刚度叠加效果，减小柱脚底板和柱脚锚栓的应力，从而可以避免柱脚底板和柱脚锚栓因应力集中而可能出现断裂的情况。当第一钢柱和第二钢柱受到相反方向的弯矩或剪力作用时，连接板可以减小第一钢柱和第二钢柱所受到的力，保证第一钢柱和第二钢柱的安全性。
