XQV PC Strand Bracket – Prestressed Concrete Strand Positioning Bracket
Product Introduction
The XQV PC Strand Bracket is a specially engineered component designed to position and support prestressing steel strands (PC strands) during both construction and service life. Its precise structural design – featuring dedicated through-holes or clamping slots – accurately restrains strands, preventing any lateral or longitudinal displacement under tension or concrete pouring.
In prestressed concrete structures, steel strands bear extremely high tensile forces. The strand bracket ensures rational stress transfer between the steel strands and the surrounding concrete, effectively generating pre-compression in the concrete. This significantly enhances the structural load-bearing capacity, crack resistance, and long-term durability of bridge girders, building slabs, and other prestressed members.
Manufactured from engineering-grade PE (Polyethylene) with excellent mechanical strength and corrosion resistance, XQV strand brackets are ideal for aggressive environments such as bridge decks, marine structures, and underground parking garages. They are lightweight, easy to install, and compatible with most standard PC strand diameters.
Key Features & Advantages
Multiple holes/clamping slots keep strands at exact design coordinates, eliminating shifting during concrete placement.
Impact-resistant polyethylene with UV resistance, long-term mechanical stability, and inertness to chemicals.
Models A-01 to D-12 cover outer diameters from 66 mm to 110 mm, adapting to various strand layouts and concrete covers.
Inert to moisture, chlorides, and most chemicals – ideal for bridge decks, marine environments, and underground structures.
Lightweight yet rigid design allows quick placement and secure fixing without special tools.
Improves load distribution and reduces micro-cracking, extending service life of prestressed members.
