Concrete filled steel tubular column and preparation method thereof
The invention relates to a concrete filled steel tubular column and a preparation method thereof, and belongs to the technical field of concrete. The concrete filled steel tubular column comprises a steel pipe and an annular steel rib stiffener arranged in the steel pipe, and concrete is poured into the steel pipe and the annular steel rib stiffener; the annular steel rib stiffener comprises a plurality of annular plates distributed in the length direction of the steel pipe, and the plurality of annular plates are fixedly connected through arc-shaped steel sheets extending in the length direction of the steel pipe; a plurality of arc-shaped steel sheets are arranged; an end plate corresponding to each annular plate is arranged on the outer wall of each arc-shaped steel sheet; a plurality of first stiffening ribs are arranged on the inner wall of the steel pipe in the length direction of the steel pipe, and the end plates are fixedly connected with the first stiffening ribs through connecting plates. The annular steel rib stiffener is arranged in the concrete filled steel tubular column, and the double constraint effects of the externally-wrapped steel pipe and the internally-arranged annular steel rib stiffener on the core concrete are utilized, so that the strength and peak strain of the concrete are improved, and the axial pressure bearing capacity and ductility of the concrete filled steel tubular column are improved.
本发明涉及一种钢管混凝土柱及其制备方法，属于混凝土技术领域。所述钢管混凝土柱，包括钢管和设置在所述钢管内的环状钢骨加劲件，所述钢管以及环状钢骨加劲件内部浇筑有混凝土；所述环状钢骨加劲件包括沿钢管长度方向分布的多个环向板，多个环向板通过沿钢管长度方向延伸的弧形钢片固定连接；所述弧形钢片设有多个；各弧形钢片的外壁对应各环向板分别设有一端板；所述钢管内壁沿钢管长度方向设有若干第一加劲肋，所述端板通过连接板与第一加劲肋固连。本发明通过在钢管混凝土柱中设置环状钢骨加劲件，利用外包钢管及内配环状钢骨加劲件对核心混凝土的双重约束作用，从而提高混凝土的强度和峰值应变，以及提高混凝土柱的轴压承载力和延性。
