Product Description:
Right-handed anchor is a commonly used geo-engineering support material, which is mainly characterized by good tensile strength and durability performance. Anchor rod full thread full length equal strength, than the same specification anchor rod bearing capacity increased by 40%; expand the scope of use of the anchor rod, can realize the end of the anchor, lengthen the anchor and the full anchor; anchor rod according to the diameter to classify, generally the most commonly used are: 16mm, 18mm, 20mm, 22mm; anchor rod body can realize with the anchor hole diameter, the diameter of the resin medicine maki a better match, has a strong anchor force, high elongation, safe and reliable, It is characterized by strong anchoring force, high elongation, safety, reliability, high quality and low consumption, easy to use, etc.The rods have rolled continuous threads with equal strength throughout their length; the fastening ends are provided with pre-stressed spacers and ball-type nuts.
Anchor material description:
High-strength anchor raw materials used in the elongation of not less than 15%, yield strength of not less than 335MPa, breaking strength of not less than 490MPa, the material of 20MnSi steel by hot lashing from 20 tons to 50 tons, Φ18 to Φ22 rod straightness tolerance ≤ 2mm / m, Φ16 rod straightness tolerance is less than 4mm / m. The rod end of the screw thread bearing capacity should be less than 75% of the breaking force of the parent material of the rod. The bearing capacity of the screw thread should be not less than 75% of the breaking force of the parent material of the rod.
Main technical performance index:
Yield strength: ≥335Mpa
Tensile strength ≥490 Mpa
Elongation: ≥15%
Anchorage force: Φ16>75kN,
Φ18>85kN,
Φ22>125kN
How to use the anchor:
1.Determine the hole position of the anchor according to the design requirements, and drill the hole with drilling equipment.
2.Blow the rock powder in the hole with pressurized air.
3. Send the anchoring agent to the bottom of the hole, hold it against the anchor and start mixing (mixing time is specified according to the type of the anchoring agent), after mixing, unload the mixing tool, after reaching the waiting time, unload the mixing connecting head, put on the anchor plate, ball washer, friction washer, and tighten the nut with a wrench.
