Split-level unequal-height special-shaped beam column joint of circular steel pipe concrete column and construction method
The invention provides a split-level unequal-height special-shaped beam column joint of a circular steel pipe concrete column and a construction method, a reinforcing ring surrounds the circumferential surface of the circular steel pipe column and is fixedly connected with the circular steel pipe column, an additional flange is arranged between the reinforcing ring and the circumferential surface of the circular steel pipe column, and a longitudinal bar in a split-level unequal-height reinforced concrete special-shaped beam bypasses the circular steel pipe column to extend; the longitudinal bars in the corresponding areas of the additional flanges are fixedly connected with the additional flanges; the reinforcing ring is connected with an additional bracket, a horizontal stiffening rib is arranged in the vertical end of the round steel pipe column, and a pouring hole is formed in the horizontal stiffening rib. The node structure provided by the invention is clear in load transmission path, does not weaken the mechanical properties of the steel pipe column and the node area, does not have a stress concentration phenomenon in the node area, is simple in force transmission mechanism, prevents local buckling of the web, realizes the synergistic effect of the steel pipe wall and the concrete, and utilizes the advantage of high bearing capacity of the concrete-filled steel pipe. And the bearing capacity, the anti-seismic property and the stability of a node area are improved, and a new design and construction process approach is developed.
本申请提供一种圆钢管混凝土柱错层不等高异型梁柱节点及构造方法，加强环环绕在圆钢管柱周面并与圆钢管柱固定连接，加强环和圆钢管柱周面之间设置有附加翼缘，错层不等高钢筋混凝土异型梁内纵筋绕过圆钢管柱延伸，附加翼缘对应区域内的纵筋与附加翼缘固定连接；加强环上连接附加牛腿，圆钢管柱竖向端部内设置水平加劲肋，水平加劲肋上开设浇筑孔。本申请提供的节点构造荷载传递路径明确，不削弱钢管柱和节点区域的力学性能，节点区域不出现应力集中现象，传力机理简单，防止腹板出现局部屈曲，实现了钢管壁和混凝土的协同作用，利用钢管混凝土承载力高的优势，提高了节点区域的承载力、抗震性能和稳定性，开辟了新的设计和施工工艺途径。
