Fabricated tough combination column adopting folded edge built-in structure
The invention discloses an assembly type tough combination column adopting a folded edge built-in structure, and belongs to the technical field of structural engineering. The fabricated tough combination column adopting the folded edge built-in structure is composed of a closed-section steel column formed by built-in internal folded edges and an externally-surrounded UHTCC (Ultra High Temperature Temperature Coefficient). And the closed-section steel column formed by embedding and fixing the folded edges is formed by splicing cold-formed section steel. The splicing mode of the cold-formed section steel is mechanical anchoring connection. And the cold-formed section steel of the closed-section column adopts step-shaped steel with grooves and folded edges at two ends. Or, curled C-shaped steel formed by folding the web is adopted. Or, curled C-shaped steel with a web plate bent in an arc shape is adopted. Holes need to be formed in the positions where the stirrups are fixed before all the cold-formed section steels are bent. The UHTCC is an ultra-high toughness cement-based composite material, and is wrapped on the periphery of the closed section column as a toughness stress component. The bent part of the cold-formed section steel can serve as a PBL shear connector to be anchored in the UHTCC peripheral layer. The assembly type tough combination column adopting the folded edge built-in structure is high in assembly degree, good in toughness, good in anti-seismic property, resistant to corrosion, convenient in pipeline arrangement and high in durability.
本发明公开了一种采用折边嵌固构造的装配式韧性组合柱，属于结构工程技术领域。所述的采用折边嵌固构造的装配式韧性组合柱由内部折边嵌固形成的闭口截面钢柱与外部包围的UHTCC构成；所述的折边嵌固形成的闭口截面钢柱由冷弯型钢拼接而成。所述冷弯型钢拼接方式为机械锚固连接。所述闭口截面柱的冷弯型钢采用两端带有凹槽和折边的阶梯形钢。或则，采用腹板对折的卷边C形钢。或则，采用腹板弧形弯折的卷边C形钢。所述所有冷弯型钢在弯折前需在箍筋固定处开孔。所述UHTCC为超高韧性水泥基复合材料，作为韧性受力构件包裹在闭口截面柱外围。所述冷弯型钢的弯折部分可作为PBL抗剪连接件锚固在UHTCC外围层中。本发明提出的采用折边嵌固构造的装配式韧性组合柱，装配化程度高，韧性好，抗震性能好，耐腐蚀，管线布置方便，耐久性强。
