Post Tension Unbonded Flat Slab Anchorage for Building Prestressed Concrete
Flat stressing anchorage consist of flat working anchor head, working wedge ,flat anchor bearing plate and flat spiral reinforcement.
The products can be divided into two types,VLM15 and VLM13 according to their strand diameters.It can be used to anchorφ12.7~12.9㎜,φ15.2~15.9㎜,standard strength 1470~1960Mpa low relaxation and high strength PC strands, and can be also to 7φ5,7φ7,strength 1470~1770Mpa PC steel wires.
As the name suggest, it is the same as stressing anchorage, only that the shape is flat. Flat stressing anchorage is common on slab on grade, side walls of hollow core beams / girders, transverse post-tensioning on box girders deck and flat slab.
VLM has innovated a flat stressing jack (YDB series) to specially cater to this flat stressing anchorage.
1. Used in pre-tension or post-tension for concrete constructions as building materials
2. Used in the upper plates of bridges
3. Used PC panels, high-pressure concrete water pipes, marine structures, towers and runways.
4. Used for multi-storey industrial/commerial/residential buildings, stadiums, coal mines and etc.
Its key part material:
slab anchorage head,swage socket 45# or 40Cr work gripper :20CrMnTi
Hardness: work anchorage head:
≤33HRC (306 HBS) work gripper :78~86HRA swage socket:≤25HRC (≤251HBS)
static load performance testing:
anchoring efficiency coefficient:ηa≥0.95;total strain:εapu≥2.0%
Wedge 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 YM15 series, it can be used for round anchorage, flat anchorage,
but also used for porous coupler.
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.
Anchor bearing plate is to transfer the load from anchor head to concrete under anchor.
The method of transfer and distribution of stress affect the anti-cracking and load capacity of concrete.
1. strictly follow ISO9001 standards, and the quality of products is controlled throughout the process.
2. all the raw materials will be tested before putting into the production.
3. all the finished products need to be tested before shipping. (Crack detection and measurement for all the anchor
heads and wedges, hardness test for the anchor heads and wedges, static load test ext)
4. Every three years, we will send our products to the national laboratory for testing of anchors.
A: Generally it is 5-10 days if we have in stock. If not it will take about 20 days, and it also depends on the order quantity.
A: Yes, we could offer the sample for free charge with freight collected.
