What is wedge and barrel?
Wedges and barrels are used for fixing the prestressing wires onto the reaction beams. Depending on the type of applications barrels may either be closed or open type. The closed type barrels have the wedges kept in place by a ring with a spring.
The Origin of Anchors
The history of anchors can be traced back to ancient times, when wooden or stone pins were already being used to secure structures on ships and buildings. However, the real modern anchorage originated in England in the early 19th century. As the Industrial Revolution progressed, the scale of construction projects grew and so did the demands for structural stability and safety. To meet these demands, British engineers designed a prestressed concrete structure and with it came anchors.
The role played by wedge and barrel
1. Fixing prestressing tendons
The main function of the anchorage is to fix the prestressing tendons. In prestressed concrete structure, prestressing tendon is a special kind of steel bar, which needs to be fixed in specified positions after tensioning to resist the prestressing force in the structure. Anchorage is the tool used to fix the prestressing tendons in these designated positions.
2.Transferring Stress
Anchorage not only needs to fix the prestressing tendons in the specified positions, but also needs to be able to transfer the stress effectively. When the structure is subjected to external loads, the prestressing tendons will generate stresses, which need to be transferred to the concrete structure through the anchorage to enhance the bearing capacity of the structure.
3.Protection of prestressing tendons
Another important role of anchorage is to protect the prestressing tendons from the influence of the external environment. Prestressing tendons need to maintain their performance for a long time after tensioning, and the anchorage can provide a good protective environment to prevent the prestressing tendons from being affected by corrosion, high temperature, low temperature and other environmental factors.
