AI Technical Summary

Technical Problem

Traditional steel bar connection methods in aqueduct structures suffer from problems such as difficulty in alignment, poor connection accuracy, and inconvenience in installation, especially in inclined sections or areas with elevation differences, which affects construction efficiency and quality.

Method used

A universal joint is used to adjust the axial angle deviation of the reinforcing bars. The first sleeve and the second sleeve are connected by forward and reverse threads. Combined with the universal joint, the reinforcing bars can be quickly connected and the angle can be compensated. The rotation adjustment of the ball head and the ball groove can automatically adapt to the axial deviation of the reinforcing bars.

Benefits of technology

It enables rapid connection of steel bars in sloping sections and staggered areas, improving construction efficiency and quality. It is highly adaptable and suitable for construction sites with limited and complex spaces.
