Post tension wedges dimensions from different companies's design
Post-tensioning wedges are typically 2-piece or 3-piece components used in post-tensioning systems to grip and anchor steel strands within a concrete structure. Their dimensions vary depending on the strand diameter they are designed to accommodate. For example, 12.7mm (0.5 inch) strands typically use wedges with a length around 30-40mm and an outer diameter of 38mm. Similarly, 15.2mm (0.6 inch) strands may use wedges with a length around 45mm and an outer diameter of 42mm according to Master Construction Technology Sdn Bhd.
Key dimensions for post-tensioning wedges include:
Strand Diameter:
This is the primary factor determining the wedge size. Common strand diameters are 12.7mm (0.5 inch) and 15.2mm (0.6 inch).
Length:
The length of the wedge varies based on the strand diameter, but is typically in the range of 30-50mm.
Outer Diameter:
The outer diameter of the wedge is also influenced by the strand diameter and is generally in the range of 30-45mm.
Number of Pieces:
Wedges can be 2-piece or 3-piece assemblies.
Material:
Post-tensioning wedges are typically made from high-strength steel, such as 20CrMnTi.
Load Capacity:
Wedges are designed to withstand specific tensile loads, which can be in the range of 200-300KN for common strand sizes according to Master Construction Technology Sdn Bhd.
Examples of wedge dimensions:
For 12.7mm (0.5 inch) strands, wedges are often around 38mm in outer diameter and 40mm in length.
For 15.2mm (0.6 inch) strands, wedges are often around 42mm in outer diameter and 45mm in length.
Additional considerations:
Wedges are often used with anchor heads and barrels in a complete post-tensioning system.
Specific wedge dimensions and configurations can vary depending on the manufacturer and the specific project requirements.
Wedges should be selected and installed according to the manufacturer's recommendations and relevant industry standards, such as those from the Post-Tensioning Institute (PTI).
