Product Description

prestressed anchorage spring screw wedge anchor   

Prestressed Anchorage for PC Strand and PC Wire

Material: Alloy steel, carbon steel, cast iron, plastic.
Parts: Anchor rings (anchor plates, barrels), inner wedges (grips, clamps), bearing plates (base plates, backing plates, block), spirals, limit plate, coupler (joints), ducts (bellows), spacers (separator) etc.
Usage: Post-tensioned concrete and pre-tensioning precast concrete, comply with 7-wire PC steel strands 9.3/9.5/9.53mm, 12.5/12.7/12.9mm, 15.2/15.24/15.7mm, 21.8mm; 3-wire PC strands 6.5/8.6/10.8mm; PC steel wires 4.0/4.8/5.0/6.0/7.0/7.5/8.0/9.0mm; PC steel bars 5.0/6.0/7.1/9.0/25/32mm etc.
Round Anchors for strands No. from 1 to 55, Flat Anchors for strand NO. from 2 to 5. 
Remarks: In pre-cast and post-tensioned prestressed concrete, anchorage anchors play a very important role. The effect of pre-stressing depends on the load that the anchors allow, and anchors' capability decides the security of pre-stressing.
