Lengthening joint containing prefabricated concrete-filled steel tube core column component and construction method of lengthening joint
The invention discloses a lengthening joint containing a prefabricated concrete-filled steel tube core column component and a construction method of the lengthening joint. The lengthening joint comprises an upper-section core column, a lower-section core column, a steel reinforcement framework, a joint concrete layer and out-of-tube concrete layers. The bottom end of the upper-section core columnis connected with an upper flange plate, the top end of the lower-section core column is connected with a lower flange plate, a connecting assembly comprises a connecting plate, bonding glue layers and high-strength bolts, the connecting plate is arranged between the upper flange plate and the lower flange plate, air holes are formed in the middle of the plate face of the connecting plate at intervals, the bonding glue layers are arranged between the connecting plate and the upper flange plate and between the connecting plate and the lower flange plate, and the upper-section core column and the lower-section core column are connected through the high-strength bolts; and the steel reinforcement framework is arranged around joints of the upper-section core column and the lower-section core column, and the joint concrete layer is poured between the out-of-pipe concrete layer on the outer side of the upper-section core column and the out-of-pipe concrete layer on the outer side of the lower-section core column. The technical problems that the thickness of an existing joint cannot be adjusted, inclination deviation exists, compression deformation is large, force transmission is not reliable, construction efficiency is low, and concrete in a steel pipe is difficult to pour are solved.
一种含预制钢管混凝土芯柱构件的接长节点及其施工方法，包括上节芯柱、下节芯柱、钢筋骨架、节点混凝土层和管外混凝土层；上节芯柱的底端连有上法兰盘；下节芯柱的顶端连接有下法兰盘；连接组件包括连接板、粘结胶层和高强螺栓；连接板设置在上法兰盘与下法兰盘之间；连接板的板面中部间隔开设有气孔；粘结胶层分别设置在连接板与上法兰盘、下法兰盘之间；高强螺栓将上节芯柱与下节芯柱连接；钢筋骨架设在上节芯柱与下节芯柱的节点周围；节点混凝土层浇筑在上节芯柱外侧的管外混凝土层与下节芯柱外侧的管外混凝土层之间。本发明解决了现有节点无法调整节点厚度、倾斜偏差、压缩变形大、传力不可靠、施工效率低、钢管内混凝土浇筑困难的技术问题。
