Product Description

pre-stressing grip wedge for precast concrete 

Post-tensioning Accessories / Prestressed Anchorage System
Items: round anchor, flat/slab anchor, circle anchor, dead anchor, coupler, duct and couple, machines etc.
Parts: anchor head/plate/ring, 2/3pcs grips/wedges, block/backing/base/bearing plate, spirals, steel/plastic duct/pipe/tube/couple, coupler/connector/joint, spacer/chair etc.
Material: alloy steel, casting iron, steel , plastic.
Usage: 1*7 PC strands 15.2/15.24/15.7mm, 12.7/12.9/12.5mm, 9.3/9.5/9.53mm, 17.8/18.0mm, 21.6/21.8mm; 1*3 PC strands 6.5/8.6/10.8mm; PC wires 4.0/5.0/6.0/7.0mm; PC bars 7.1/9.0/25/32mm etc.
Remarks: in post-tensioned structure of pre-stressed concrete, anchorage anchors play a very important role. The effect of pre-stressing depends on the load that the anchors allow, and anchors' capability influences the security of the post-tensioned structure directly.
