AI Technical Summary
Technical Problem
The existing prestressed anchor tensioning and locking auxiliary support screw structure has poor compressive stability under high prestress loads, is prone to elastic buckling or plastic deformation, and has a short service life.
Method used
The traditional screw support is replaced by a structure that combines an H-shaped base with a panel and side plates, forming an L-shaped rigid angle structure. This enhances the bending and compressive stiffness of the support and reduces deformation by utilizing the excellent compressive strength of the H-shaped base.
Benefits of technology
This improved the structural stability and torsional resistance of the support structure, extended its service life, and ensured the reliability and safety of prestress transfer.
