Steering supporting structure for prestressed cable of lattice tower
By setting steering and positioning components at the corners of the lattice tower, the surface contact between the steel strand and the steering component is achieved, which solves the problem of radial shear force of the prestressed cable at the corner and extends the service life of the steel strand.

AI Technical Summary
Technical Problem
After tensioning, the prestressed cable makes point and line contact with the corner of the lattice tower, resulting in radial shear force, which can easily cause the steel strand to break and affect its service life.
Method used
A columnar steering component is installed at the corner of the lattice tower. The steel strand and the steering component are in surface contact to avoid point or line contact. The radial shear force is reduced by the design of the through hole, and the position of the steering component is stabilized by the positioning component.
Benefits of technology
This effectively avoids the influence of radial shear force on the steel strand, extends the service life of the steel strand, and ensures normal use.

Abstract
The utility model belongs to wind power towers, and particularly relates to a prestressed cable steering supporting structure of a lattice tower, a tower body is formed by connecting a foundation section and a vertical section from bottom to top, and a tubular lattice column extending from the top end of the vertical section to the bottom end of the foundation section is arranged between adjacent side faces of the tower body. A corner point with a notch facing the outer side of the tower is arranged at the position, located at the joint position of the foundation section and the vertical section, of the latticed column, an upper anchorage device and a lower anchorage device are arranged at the top end and the bottom end of the latticed column correspondingly, and a columnar steering piece is arranged at the position, close to the corner point, in a pipe cavity of the latticed column. The steel strands penetrate through the corresponding through holes in the steering part, the contact parts between the steel strands and the steering part form surface contact type matching, the situation that protruding radial shear force point positions are generated due to point and line contact does not exist between the steel strands and the steering part, and the situation that the steel strands are fractured due to the influence of radial shear force is effectively avoided; and the normal service life of the steel strand is ensured.
