Post Tension Unbonded Flat Slab Anchorage for Building Prestressed Concrete

Description

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.

Application

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.

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.

Quality control

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.
