What is the anchor head in post-tensioning system?

Production of Post Tensioning Accessories (Anchor Head & Wedge)

 

This simple video captures some process in our production of post tensioning accessories, namely Anchor Head and Wedge.

Anchor Head (also commonly known as Wedge Plate) is an important part of the post tensioning system. It works in tandem with the Wedge that holds the individual tensile element. The prestressing load is then transfer to the Bearing Plate. For some small tendon sizes, this prestressing force can be transferred directly to the structure without the need of Bearing Plate.

In the case of some mono anchorage system, the Wedge will hold an individual tensile element directly to the Bearing Plate.

Anchor Head and Wedge is subjected to Static Load and Fatigue (Reliability) Test. Hence its design and production quality control is of paramount importance.

Static Load Test requires the Anchor Head and Wedge to hold to a specific percentage (>95%) of the tensile element ultimate strength with a minimum elongation (>2%), with without premature failure of anchorage components, without undue deformations in the components, and without disproportionate relative movements between tensile elements and anchorage components.

As for Fatigue Test, the Anchor Head and Wedge have to go through 2 million cycles of fatigue loads (dynamic strength, 80MPa) without exceeding a specified percentage loss of tensile element cross section (<5%).

We hope this video provides some insight of our production process and gives our operators a better understanding of our commitment to quality control.

Post tension anchor heads
We are a professional company which has produced post tension anchor heads for more than ten years. Post tension anchor heads have been widely adopted by concrete structure construction, especially used in post-tension for concrete constructions as building materials, such as bridge construction, road construction, railway and highway construction, buildings and channel construction, etc.
Post tension anchor heads are permanent anchoring device used in post-tensioned structures or components to maintain the tensile force of prestressed tendons and transfer them to mixed tension in post-tensioned structures or members. Also known as prestressed anchors. The tensioning end anchor is composed of four parts: wedges, anchor ring, anchor bearing plate and spiral reinforcement. 
Our post tension anchor heads include 12.7mm or 15.24mm round anchor heads and flat anchor heads. The round anchor head is made by 45# high-quality carbon construction steel, and the flat anchorage is made by 40Cr steel. The round anchor heads have 1-55 strands for option, the flat anchorage have 2-5 strands for option. 
Wedge is the key part of anchor system, which is made by high-class alloy steel 20CrMnTi. Its form is divided into two parts and three parts. It can be used for
The post-tensioning method is a method of pouring concrete first and then tensioning the reinforcement. When making a component or block, pre-stressed holes are placed in the place where the prestress is placed. After the concrete reaches the strength specified in the design, the prestressed ribs are inserted into the reserved holes and the prestressed ribs are stretched to After designing the prescribed control stress, the prestressed tendons are anchored at the end of the component with the aid of post tension anchor heads, and finally the hole grouting is performed.
The method of applying pre-compressive stress to the tension zone of the concrete member is to stretch the pre-stressed steel bar in the tension zone, and transfer the elastic shrinkage force of the pre-stressed steel bar to the prestressed steel bar through the bonding force or anchor In concrete members, prestressing stress is generated. This delays the appearance of concrete cracks, and also limits the development of cracks, thereby improving the crack resistance and rigidity of the component.
The post-tensioning method is suitable for the on-site production of large-scale prestressed components, special structures and structures, and can also be used as a prestressed component assembly method. Superiority of post tension anchor heads:
1. Easy to use. The utility model has the advantages of simple structure, light weight, reliable work and convenient installation and maintenance.
2. High work efficiency and better quality than other domestic products.
3. Durable. Small size, high efficiency, good quality and durability.
Application of post tension anchor heads:
1. Railway: High degree of automation and high production efficiency, making production and processing easy and efficient.
2. Hydropower: simple structure, light weight and small size.
3. High-rise building: reliable work, easy installation and maintenance.
4. Highway: It can be used repeatedly for the use of long prestressed tendons, which can be used repeatedly and save costs.
Before we send quotation, please let us know the following items:
1. What's diameter do you want? 12.7mm or 15.24mm?
2. How many strands do you stress by one complete of anchor system?
3. For a complete set of anchor system, do you need two sets, three sets or four sets? 
4. Do you need round(circular) anchor or flat anchor?
5. What is the quantity of each kinds do you need?
