Barrel and Wedges

Product Overview

Barrel and Wedges are critical components used for anchoring single prestressing strands in post-tensioned concrete structures. Together, they form a compact and efficient anchoring system widely used in bridges, buildings, geotechnical engineering, and other post-tensioned applications.

Barrel

Features & Advantages

Superior Material: Made from high-quality alloy steel through forging or precision casting, followed by heat treatment for high strength, hardness, and good toughness.

Precision Design: The optimized internal taper ensures a perfect match with the wedges, guaranteeing even stress distribution.

Corrosion Resistance: Typically features galvanized, epoxy-coated, or other anti-corrosion finishes for durability in harsh environments.

Complete Specifications: Compatible with various strand diameters (e.g., 15.2mm, 15.7mm).

Wedge

Features & Advantages

Two or Three-Piece Design: Typically consists of two or three segments forming a complete tapered ring, facilitating installation and even gripping.

High-Hardness Teeth: The inner surface features precision heat-treated teeth that effectively grip the strand to prevent slippage while avoiding damage to the core.

Matched to Barrel: The external taper angle precisely matches the barrel's internal taper, ensuring self-locking anchorage.

Applications

Prestress construction of precast beams, box girders, T-beams

Slabs, roofs, and other building structures

Geotechnical engineering like slope anchoring, foundation pit support

Other concrete structures requiring post-tensioning
