Rebar Description

Generally applicable to mine roadways, bridges and tunnels, rail slopes, etc. to strengthen the support, the general anchor hole is to use the anchor drilling rig to drill holes, and then put the appropriate anchoring agent (resin medicine roll), and then use the anchor drilling rig and other tools to drill the anchor into the anchor hole to the anchoring agent for stirring anchor, and then use the anchor drilling rig and other tools to its nut installation; right-handed anchors are a very practical geo-engineering support materials It has good tensile strength and corrosion resistance. When it is used, attention should be paid to the maintenance and care in terms of safety, stability and durability to ensure its long-term and effective function.

Rebar Anchor Structure

Rod body, anchor disk, ball washer, friction washer, nut, rod body has rolled continuous threads throughout its length, equal strength throughout its length; fastening end is provided with pre-stressing spacer and ball-shaped nut.

Anchor Technical Characteristics

  Anchor according to the diameter to be classified, generally the most commonly used are: 16mm, 18mm, 20mm, 22mm; anchor rod body can be realized with the anchor hole diameter, resin maki diameter better match, with strong anchor force, high elongation, safe and reliable, high quality and low consumption, easy to use and so on.

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 for the 20MnSi steel by hot lashing and become, respectively, compressive 20 tons to 50 tons, Φ18 to Φ22 rod straightness tolerance ≤ 2mm / m, Φ16 rod straightness tolerance is less than 4mm / m. Rod tail The bearing capacity of the screw thread should be not less than 75% of the breaking force of the parent material of the rod.

The company mainly supplies the following products: 

16# no longitudinal rib (equal strength) threaded anchor, 18# no longitudinal rib (equal strength) threaded anchor, 20# no longitudinal rib (equal strength) threaded anchor, 22# no longitudinal rib (equal strength) threaded anchor, 24# no longitudinal rib (equal strength) threaded anchor.
