Introduction to Prestressed Tensioning Anchor Products

1. Product Overview

Prestressed tensioning anchors are core components in prestressed engineering, primarily used to secure and transfer the tension of prestressed tendons (such as steel strands, wires, or rebars), ensuring the stability and durability of concrete structures under stress. They are widely used in bridges, buildings, tunnels, water conservancy, and other engineering fields.

2. Main Types

Based on tensioning methods and structural forms, prestressed tensioning anchors are mainly categorized as follows:

(1) Wedge-Type Anchors

• Features: Utilize conical wedges to grip steel strands, suitable for post-tensioned prestressed construction.
• Common Models: YM, OVM, HVM, BM series, etc.
• Applications: Bridges, large-span buildings, prestressed concrete beams, etc.

(2) Squeeze-Type Anchors (P-Type Anchors)

• Features: Fix steel strands through mechanical squeezing, suitable for end anchoring.
• Applications: Cable-stayed bridges, suspension bridges, continuous beams, etc.

(3) Button Head Anchors

• Features: Use cold or hot heading processes to secure wire ends, suitable for high-strength wire bundles.
• Applications: Large-span roof trusses, sleepers, pipe piles, etc.

(4) Nut Anchors

• Features: Secure prestressed tendons through threaded connections, suitable for tensioning precision-rolled threaded rebars.
• Applications: Slope support, foundation pit support, bridge reinforcement, etc.
