Steel tube tower plane TY type tubular joint construction method capable of improving ultimate bearing capacity
The invention discloses a steel tube tower plane TY type tubular joint construction method capable of improving ultimate bearing capacity. The problem that local buckling is prone to occurring when extra-high voltage and ultrahigh voltage transmission line steel tube towers adopt traditional TY type tubular joint structures is solved. A first branch pipe (1) and a second branch pipe (2) are welded to a main pipe (3), the main pipe (3), the first branch pipe (1) and the second branch pipe (2) are arranged in a TY shape, and a main pipe inner cavity cross-shaped stiffening plate (4) is arranged in a pipe cavity of the main pipe (3) in the central axial direction of the main pipe (3). A main pipe inner cavity annular plate (5) is arranged in the pipe cavity of the main pipe (3) along the annular direction of the circular inner cavity of the main pipe (3); the main pipe inner cavity cross-shaped stiffening plate (4) and the main pipe inner cavity annular plate (5) are vertically arranged and are fixedly connected together; and local buckling of the main pipe is effectively prevented.
本发明公开了一种可提高极限承载力的钢管塔平面TY型相贯节点构建方法，解决了特高压及超高压输电线路钢管塔采用传统的TY型相贯节点结构容易发生局部屈曲的问题。在主管（3）上焊接有第一支管（1）和第二支管（2），主管（3）、第一支管（1）与第二支管（2）是呈TY型设置的，在主管（3）的管腔内，沿主管（3）的中心轴向方向，设置有主管内腔十字型加劲板（4）；在主管（3）的管腔内，沿主管（3）的圆形内腔环向，设置有主管内腔环板（5）；主管内腔十字型加劲板（4）与主管内腔环板（5）彼此垂直设置，并固定连接在一起；有效防止主管发生局部屈曲。
