Anchorages are key devices used in prestressed concrete projects for permanently anchoring steel wires, steel strands or reinforcing bars. They are mainly divided into tensioning end anchorages and fixed end anchorages, and are widely applied in fields such as bridges and buildings.
Classification and Structure
Tensioning End Anchorages: Used for tensioning prestressed tendons, including clip-type anchors (such as YJM), steel conical anchors (GZM), and pier-head anchors (DM), etc. They must comply with the standards of GB/T 14370-2015.
Fixed-end anchor: Embedded in concrete, such as the compression anchor (P anchor), it mechanically interlocks with the steel strands through a compression spring.
Application fields
Highway bridges, railway bridges, urban overpasses, water conservancy projects, tunnels, port terminals, etc.
In the unbonded prestressing system, the unbonded steel bar anchor is composed of anchor plates, anchor nuts, etc., and is suitable for external prestressing projects. 1
