Prestressed Tensioning Anchor SM15-15 Hole Anchor Custom Processing Deeply Embedded Sleeve Anchor Tensioning Anchor Contact Me

It is an anchoring device used in prestressed concrete structures, primarily for securing prestressed steel strands or wire bundles and transferring the prestress to the concrete structure. Unlike ordinary anchors, deeply embedded anchors are typically buried deeper within the concrete to enhance anchoring reliability and durability.

Characteristics of Deeply Embedded Anchors

1. High Anchoring Performance: Suitable for large-tonnage prestressed structures, capable of withstanding high tension forces.
2. Strong Durability: Reduced impact from external environments (such as corrosion and impact) due to deeper embedding.
3. Reduced Stress Concentration: The deep embedding design helps disperse stress, avoiding local damage to the concrete.
4. Suitable for Complex Structures: Commonly used in projects such as bridges, large-span buildings, and nuclear power plants.

Common Types

• Post-Tensioning Deeply Embedded Anchors: Used in post-tensioned prestressed concrete structures, Prestressed Tensioning Anchor SM15-15 Hole Anchor Custom Processing Deeply Embedded Sleeve Anchor Tensioning Anchor Contact Me such as prestressed box girders in bridges.
• Pre-Tensioning Deeply Embedded Anchors: Used in pre-tensioned prestressed components, such as sleepers and pipe piles.
• Replaceable Anchors: Facilitate later maintenance and replacement.

• Introduction to Deeply Embedded Anchor Construction

  The construction of deeply embedded anchors involves several key steps, including preliminary preparation, anchor installation, prestressed tensioning, and grouting sealing.

  1. Pre-Construction Preparation

  (1) Material and Equipment Inspection

  • Anchors and Accessories: Check if the model and specifications meet design requirements Prestressed Tensioning Anchor SM15-15 Hole Anchor Custom Processing Deeply Embedded Sleeve Anchor Tensioning Anchor Contact Me, ensuring no rust, deformation, or cracks.
  • Prestressed Tendons (Steel Strands/Wire Bundles): Inspect strength, diameter, and surface quality to ensure no damage.
  • Grouting Materials: Use specialized cement slurry or epoxy resin to ensure fluidity and strength comply with standards.
  • Tensioning Equipment: Jacks, oil pumps, pressure gauges, etc., must be calibrated and qualified to ensure accurate tensioning force.

  (2) Concrete Structure Inspection

  • Check if the concrete strength in the anchoring area meets design requirements (generally ≥80% of the design strength).
  • Ensure the anchor installation position is accurate, with no blockages, deformation, or misalignment in the reserved channels.
