Product Description

Grip Wedges: Key Components for Prestressed Anchorage Systems

Grip Wedges are crucial components in prestressed anchorage systems, playing a pivotal role in ensuring the stability and reliability of prestressed structures. Specifically crafted with 20CrMnTi material — a high - performance alloy steel — these wedges are engineered to securely grip and anchor prestressing tendons. They are instrumental in transferring and sustaining prestress, thus guaranteeing structural stability, strength, and durability across a wide range of construction projects.

Product Advantages

High - Precision Fit

Advanced machining, paired with the inherent properties of 20CrMnTi, ensures precise tapers and tooth profiles. This enables seamless integration with anchor heads and tendons, facilitating even stress distribution and reliable anchorage.

Strong Grip & Longevity

Constructed from 20CrMnTi alloy steel, and further enhanced through heat treatment (achieving a hardness of HRC58 - 62) and surface strengthening (with a penetration layer of 0.5 - 0.7), these wedges offer high hardness, toughness, and wear resistance. They firmly hold tendons, maintaining grip under dynamic loads and harsh conditions for extended service life.

Versatile Use

Adaptable to various prestressed applications like bridge post - tensioning, high - rise construction, tunnel support, and structural reinforcement. Compatible with different tendon sizes and anchor types, fitting diverse project requirements.

Application Scenarios

Bridges & Viaducts

Essential for anchoring prestressing tendons in box girders, T - beams, etc. The 20CrMnTi - based design, with its optimized hardness and wear resistance, improves load - bearing capacity and crack resistance, ensuring long - term safe operation of bridge structures.

High - Rise & Industrial Buildings

Used in prestressed floor slabs, beams, and columns. Leveraging the material’s strength and treatment benefits, they help reduce self - weight, enhance structural stiffness, and control cracks — ideal for large - span, heavy - load construction.

Tunnel & Underground Engineering

Supports rock/soil reinforcement by anchoring prestressed cables. The robust 20CrMnTi composition stabilizes tunnel surrounds, prevents deformation, and suits projects like subway stations, mine tunnels, etc.

Structural Reinforcement

Enables effective prestress application in retrofitting projects (e.g., floor opening, load increase). The wedges’ precision and durability, rooted in their material and treatment, restore and enhance structural performance.
