Plastic bracket for prestressing strand (also called isolation bracket, centering bracket or expansion ring) is a key accessory in the prestressing anchorage system, and its main uses and functions are as follows: Rationalize strand arrangementPrevent multiple strands from entangling, crossing or knotting each other when bunch strands are threaded into the hole to ensure smooth bunching.Ensure uniform stress in anchored sectionBy expanding the strand spacing, each strand is evenly dispersed at the anchored end, avoiding stress concentration and improving the overall anchoring reliability.
Spatial positioning effect
Plastic bracket with built-in separating slot precisely isolates and fixes each strand in the set position, forming a stable ring structure and maintaining the strands in parallel rows.
Optimize grouting effect
After expanding the strand spacing, the cement paste can fully fill the gaps between strands, forming a uniform coating, enhancing corrosion protection and improving the strength of anchors.
Enhance anchorage reliability
Avoid localized extrusion and friction of strands, ensure synchronized force on strands during tensioning, and reduce the risk of fracture due to uneven force.
The products are used in wind power projects, nuclear power construction, offshore/onshore photovoltaic flexible bracket fittings and materials supply, wind mixing tower anchor cable fittings supply and construction maintenance, LNG storage tank anchor cable fittings, mining and other supply and construction maintenance.
The company has advanced production equipment and scientific production management system, over the years, We co-operate with different partners to serve the domestic infrastructure market.
