Concrete-filled steel tube stiffening mixed structure column, column-beam connecting joint and construction method
The invention discloses a prefabricated concrete-filled steel tube reinforced composite structure column which comprises a steel tube and a high-strength concrete layer. The steel pipe is wrapped with the high-strength concrete layer, the steel pipe and the high-strength concrete layer are coaxially arranged, and the upper end or the lower end of the steel pipe axially extends and extends out of the high-strength concrete layer; the high-strength concrete layer is provided with longitudinal steel bars, and the upper ends or the lower ends of the longitudinal steel bars axially extend out of the high-strength concrete layer. The invention further discloses a prefabricated concrete-filled steel tube structure column-beam mixed connection joint which comprises an upper structural column, a lower structural column, a cast-in-place ring beam and a cross beam. The steel pipes of the upper and lower structural columns, the high-strength concrete layer of the upper structural column and the cast-in-place ring beam form a whole through the cast-in-place concrete layer; and the end part of the cross beam is connected with the cast-in-place ring beam. The concrete-filled steel tube reinforced mixed structural column has the beneficial effects that the concrete-filled steel tube reinforced mixed structural column is adopted, and the longitudinal steel bars are arranged in the structural column, so that the strength of a connecting joint is improved; the steel pipes of the upper and lower structural columns extend, are welded and are poured with concrete, so that the compactness of grouting in the template is conveniently detected, the construction quality is ensured, and the node is safer and more reliable.
本发明公开了一种预制钢管混凝土加劲混合结构柱，包括钢管和高强混凝土层；所述高强混凝土层包裹在钢管外部，二者同轴配置，且钢管的上端或下端轴向延伸并伸出高强混凝土层；所述高强混凝土层设纵向钢筋，纵向钢筋的上端或下端轴向延伸并伸出高强混凝土层。本发明还公开了一种预制钢管混凝土结构柱梁混合连接节点，包括上结构柱、下结构柱、现浇环梁和横梁；上下结构柱的钢管、上结构柱的高强混凝土层和现浇环梁通过现浇混凝土层形成一个整体；所述横梁端部与现浇环梁相连。本发明的有益效果为：采用钢管混凝土加劲混合结构柱，这一结构柱内设纵向钢筋，提高了连接节点的强度；上下结构柱的钢管延伸焊接并浇筑混凝土，便于检测模板内灌浆的密实度，保证了施工质量，节点更加安全可靠。
