Types of Post Tensioning Anchor

Anchors are commonly used at home and abroad according to the process of organic processing anchors and casting anchors.

According to the shape is divided into square anchors, round anchors, flat anchors, and cylindrical anchors.

According to the number of holes can be categorized into single-hole anchors and multi-hole anchors.

Structure of Post Tensioning Anchor

The anchor is divided into anchor plate and anchor head/barrel.

The function of anchor plate is to pass through and collect the strand, and at the same time keep the grouting hole for cement grouting.

The anchor head/barrel inserts the anchor plate and forms an anchor wedge with the strand.

Cast anchors are mostly used in bridge construction, round anchors are mostly used in coal mine construction, and single-hole anchors are mostly used in slopes, houses and high-rise buildings. And the most used are 3-hole and 5-hole anchors.

Meanwhile, our company can also customize the anchors according to your requirements.

How To Use Post-Tensioning Anchors

Post-tensioning anchors are used in construction to enhance the strength and durability of concrete structures. The process involves placing tendons, typically made of high-strength steel, within the concrete and then applying tension to them after the concrete has hardened. This helps to counteract the forces that the structure will face during its lifespan. Here's a general guide on how to use post-tensioning anchors:

Design and Planning:

Engage a structural engineer to design the post-tensioning system based on the specific requirements of your project. Plan the layout of the tendons and determine the number, size, and location of the anchors.

Installation of Ducts:

Install ducts or sleeves within the concrete forms before pouring. These ducts will house the tendons. Ensure that the ducts are correctly aligned and secured to prevent movement during concrete placement.

Tendon Placement:

Place the tendons inside the ducts according to the design specifications. Ensure that the tendons are properly supported and positioned to achieve the desired structural effect.

Concrete Placement:

Pour the concrete into the forms, making sure it completely surrounds the tendons and ducts. Consolidate the concrete to eliminate air voids and ensure proper bonding with the tendons.

Curing:

Allow the concrete to cure to the specified strength before applying any tension to the tendons.

Anchoring:

Connect one end of the tendons to a stressing bed or hydraulic jack. Use the stressing equipment to apply tension to the tendons gradually. This process is known as "stressing" or "post-tensioning." Anchor the other end of the tendons using post-tensioning anchors.

Grouting:

Inject grout into the ducts under pressure after tensioning to fill any voids and ensure a solid bond between the tendons and the concrete.

Final Adjustments:

Make any necessary adjustments to the tension in the tendons to achieve the desired structural performance.

Protection:

Provide protection against corrosion by applying appropriate coatings to the tendons or using corrosion-resistant materials.

Documentation:

Document the post-tensioning process, including the type and location of anchors, the amount of applied tension, and any adjustments made.

It's crucial to follow industry standards and guidelines during the entire post-tensioning process to ensure the safety and integrity of the structure. Additionally, consult with a qualified engineer for specific project requirements.
