Definition of Parts:

Anchor head is the key part of bearing the prestressing tension, The round anchor head is made by 45# high-quality carbon construction steel, and the flat anchorage is made by 40Cr steel. Anchor head include round anchor head and flat anchor head

Wedge is the key part of anchor system, which is made by high-class alloy steel 20CrMnTi. Its form is divided into two-chip and three-chip. The system apply to the two-chip YJM15 series, it can be used for round anchorage, flat anchorage, but also used for porous coupler

Pre-stressed Anchorage Accessories
Material: Alloy steel, carbon steel, cast iron, plastic. 
Parts: Anchor rings (heads, plates, barrels), inner wedges (grips, grippers, clamps), bearing plates (base plates, backing plates, block), spirals, limit plate, coupler (joints, connector), GI/HDPE corrugated ducts/pipes/tubes (bellows), PVC plastic spacers (separator, support) etc. 
Usage: Post-tensioned concrete and pre-tensioning precast concrete, comply with 7-wire PC strand 9.3/9.53mm, 12.5/12.7/12.9mm, 15.2/15.7mm, 17.8/18.9/21.8mm; 3-wire PC strand 6.5/8.6/10.8mm; 19-wire strands 21.8/28.6mm; PC wire 4.0/4.8/5.0/6.0/7.0/8.0/9.0/10mm; PC bar 5.0/6.0/7.1/9.0/ etc. 
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. 



Flat Stress Anchors is generally used for building post tensioning slab, flat slab, side walls of hollow core beams / girders, transverse of box girders deck / top slab, etc.

Flat Stress Anchors are generally applied on thin post tensioning slab with the concrete strength keeping the slab in compression. Large and long spans are possible as the tendon profiles are designed to counteract deflections using prestressing force. Material usage is also minimized and reduced with post tension slab as compared to conventional reinforced concrete designed slab. This is particularly obvious in building construction.
