prestressed barrel and wedge

详情

1.      Product Introduction:

Prestressed tendons in anchorage installed in anchor cable steel strand) exposed and can be tensioned anchorage, after tensioning preload tension of the prestressed reinforcement can be passed to the surface of concrete or steel structure, increase the overall strength of the effect. Special analysis, tunnels, Bridges and other prestressed tensioning construction engineering.

2.      The performance parameters:

the diameter of the steel strand           *2.7mm

the tensile strength of steel strand            ≤***0Mpa

The efficiency coefficientη                   ≥*5%

The assembly stress length of total strain   εapu ≥2.0%

pitch                                           *6mm

Execution standard                         GB/T *********7

3.      The unique features:

Anchor piece tooth type is reasonable, unique small damage degree of anchor cable surface, grasping the anchor cable is firm and reliable. Anchor for three disc, incision is bevel, and steel wire spiral to the contrary, more uniform distribution of steel strand monofilament passed the tensile force, anchor follow-up effect is good. Efficiency coefficient is high, safe and reliable support.

4.      packaging:

Kraft paper carton packaging, each anchorage is  independently encapsulated by plastic bags .
