Nested steel column-concrete column connecting structure
The invention discloses a nested steel column-concrete column connecting structure. The nested steel column-concrete column connecting structure comprises a steel column and a concrete column which are connected up and down, the steel column comprises an external steel pipe, concrete and longitudinal bars, and the concrete and the longitudinal bars are poured in the steel pipe; studs are fixed to the periphery of the interior of the steel pipe, and the longitudinal bars penetrate through the concrete column on the lower part and the steel column in the middle; the concrete column further comprises stirrups surrounding the longitudinal bars, and the concrete in the steel column and the concrete column are poured at the same time; and the outer diameter of the steel column is defined as D1, the diameter of the concrete column is defined as D2, and D2 is larger than or equal to D1 and smaller than (D1+200 mm). The nested steel column-concrete column connecting structure ingeniously utilizes extrusion of the concrete core column and the steel column to transmit bending moment. Meanwhile, a bearing device is arranged in the steel pipe, and the axial force is transmitted through inverted stiffening ribs and column foot plates. The nested steel column-concrete column connecting structure is novel and unique in form, simple in structure and clear in stress.
本发明公开一种嵌套式钢柱‑混凝土柱连接结构，其包括上下连接的钢柱和混凝土柱，所述钢柱包括外部的钢管以及位于钢管内部浇筑的混凝土和纵筋；所述钢管的内部四周固定栓钉，所述纵筋贯穿下部的混凝土柱和中部的钢柱；所述混凝土柱还包括围绕纵筋的箍筋，且钢柱内部的混凝土和混凝土柱同时浇筑；定义所述钢柱的外径为D1，混凝土柱的直径为D2，则D1≤D2＜D1+200mm。本发明的结构巧妙利用混凝土芯柱与钢柱的挤压传递弯矩。同时，在钢管内设置承托装置，利用加劲肋和柱脚板倒置传递轴力。该结构形式新颖独特、构造简单、受力明确。
