LQM bridge building precast concrete slab

Product description

LQM post tensioning products precast concrete slab are designed and manufactured under quality control program to meet international standards.

LQM post-tensioning system consists of stress-end anchorage( precast concrete slab
), fixed-end (dead-end )anchorage, plastic or metal corrugated duct, coupler and PC strand.

LQM post-tensioning systems mating strands with various diameters: LQM13 for strand diameter 12.5/12.7/12.9mm, LQM15 for strand diameter 15.24/15.3/15.7mm, LQM18 for strand diameter 17.8mm, LQM22 for strand diameter 21.8mm.

Feature:

1.Adapatable for strand which with various strength such as 1570/1670/1770/1860/2000 MPaand various diameters.

2.Full range of tendon sizes are availabel(1-55 strands and larger sizes are available on request).

3.No need to determine strand length in advance.

4.High anchoring coefficient, reliable and stable.

For LQM post-tensioning system:

Anchor coefficient: η_a≥0.95

Total strain at ultimate tensile force: ε_apu≥2%

5.simple and reliable equipment for installation, tensioning and grouting.
