PC bar for mine anchor cable (mine supporting big diameter PC bar)
This product is heat-treated spiral rib bar with resin anchoring structure for mine anchor cable. Its specifications are φ16.0mm, φ18.0mm, φ20mm, and the tensile strength grade are 1080Mpa, 1270Mpa, and 1420Mpa. The product has the characteristics of high strength, high toughness, low relaxation, total elongation under maximum force Agt≥3.5% and impact absorption energy Akv/J≥32. Its shape is spiral rib. It is a new type of support material that combines the advantages of ordinary resin anchor rod and high-strength PC strand materials. During application, it adopts tensioning method to apply preload and only the tail of the bar is stretched to avoid the torsion of traditional anchor rods caused by applying preload through pre-tightening torque and breakage in shear. The tensioning method can also greatly increase the pre-tightening force and improve support effect. It is a new type of material for mine support.
