Advantages of Rebar Anchor
Right-handed equal-strength threaded steel resin anchor rods can realize a good match with the diameter of the anchor hole and the diameter of the resin maki-e roll, which has the characteristics of strong anchoring force, high elongation, safety and reliability, high quality and low consumption, easy to use and so on. Anchor high strength, reasonable structure, anchor full thread full length equal strength, solved the anti-twist anchor thread and pat flat at the low strength of the shortcomings; than the same specifications of the anti-twist anchor bearing capacity increased by 40%; easy to operate, inexpensive, able to automatically adjust the direction of the force to increase the binding force on the surrounding rock, can realize the rapid installation of the mechanization, can be end of the anchor, the extension of the anchor and the whole anchor, mainly used for the high ground pressure of the mine with large deformation of the roadway It is mainly used for high strength support of large deformation roadway in high pressure mines, and is widely used in coal mines, railroads, hydropower and other projects for all kinds of roadway support.
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:
