What is the Role of Anchors in Engineering Applications?

As a supplier of prestressed anchors, our company has always been guided by engineering needs. From raw material selection to process control, we strictly abide by standards to ensure quality and quality, because we are well aware of the "big role" of this "small component" in engineering safety - although the anchor is small in size, it is the core hub of the prestressed system. It can accurately fix prestressed tendons such as steel strands and steel bars, and inject prestressed stress into concrete structures by efficiently transmitting tension. It shoulders the dual mission of permanent anchoring and stress conduction. The role of anchors in engineering is as follows:

1. Fix the prestressed tendons to achieve effective stress transfer

- Tensioning stage: The anchors and jacks work together to firmly clamp the prestressed tendons and bear the tensioning load, ensuring that the tensioning force is accurately applied according to the design value to avoid slipping or stress loss.

- Anchoring stage: After the tensioning is completed, the prestressed tendons are locked through components such as clips and nuts to stably convert the tensioning force into the prestressed stress of the concrete structure, so that the stress relaxation rate is controlled at ≤5%, ensuring the long-term stability of the prestressed system.

2. Adapt to the needs of multiple construction scenarios

- Prefabricated building connections: In the splicing of prefabricated beams, columns and other components, the anchors form an integral force-bearing structure by tensioning prestressed tendons, such as the connection of prestressed concrete pipe piles, to improve assembly efficiency and structural integrity.

- Precise application in special projects:

     - Bridge cable anchors: can withstand ultra-high stress >2000MPa, firmly fix the steel cables and transfer the bridge deck load, and ensure the wind and earthquake resistance of the cable-stayed bridge;

     - Mine tunnel anchors: cooperate with anchor rods to anchor the rock layer, maintain the stress balance of the surrounding rock, and effectively prevent landslide accidents;

     - Large roof cable net anchors: fix the boundary force of the cable net, support large-span roof structures (such as gymnasiums and exhibition centers), and achieve lightweight design. 

3. Ensure construction safety and long-term durability

- Standardized construction guarantee: anchors are used in conjunction with through-type jacks and other equipment, the construction process is standardized, the tension force can be quantified and controlled, reducing human operation errors and improving construction efficiency.

- Material and anti-corrosion design: high-strength materials such as 45# steel and alloy tool steel are used, combined with anti-corrosion treatments such as anti-rust paint and galvanizing to resist environmental erosion and extend service life.

- Strict prevention and control of failure risks: Each batch of anchors passes the static load test (efficiency coefficient η≥0.95, breaking elongation ≥2%), preventing the collapse of the prestressed system caused by anchor slippage from the source - historical cases show that accidents such as bridge collapse and structural cracking are mostly related to the failure of the anchoring area, so the reliability of anchors is an important line of defense for engineering safety.

Summary

Anchors are the "invisible cornerstone" of prestressed engineering, which directly determines the safety and durability of engineering structures. The anchors we produce strictly follow the above technical standards, and pass the whole process quality inspection to ensure that each batch of products meets the requirements of static load test. We also provide multiple specifications to adapt to different prestressed tendons (steel strands, steel bars, etc.) to meet the needs of multiple projects such as bridges, buildings, and mines. If you need to customize the plan according to the characteristics of the project or understand the specific specifications, please feel free to contact us by phone or email at any time. We will provide you with a precisely adapted anchoring solution.
