Rebar

Descriptive:

Rebar is a widely used rebar material in the construction and engineering sectors, offering high strength and good resistance to compression and bending, and Mining Rebar, a specialized rebar product for the mining industry, is abrasion and corrosion resistant, and maintains a stable performance in harsh environments. The associated Equal Strength Threaded Anchor Rod provides an even stronger connection through a threaded joint, further enhancing structural stability and reliability. This combination of Rebar and Equal Strength Threaded Anchor Rod design not only ensures the safety and stability of the project, but also improves the longevity and maintenance efficiency of the facility. In construction and engineering projects, choosing the right Rebar product can provide reliable support and security for the project.

The weight of the left and right rotating anchors:

Anchor Details:

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 for nut installation; anchor full thread full-length and other strengths, compared with the same specification anchors Load carrying capacity increased by 40%; expand the scope of anchor use, can realize the end anchor, lengthening anchor and full anchor; easy to operate, low price and other advantages, widely used in coal mines, railroads, hydropower and other projects of various types of roadway support.

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 are made of steel with elongation not less than 15%, yield strength not less than 335MPa, breaking strength not less than 490MPa, made of 20MnSi steel by hot lashing, with compression resistance from 20 tons to 50 tons, straightness tolerance of Φ18 to Φ22 rods is ≤2mm/m, and the straightness tolerance of Φ16 rods is less than 4mm/m. The carrying capacity of the tail thread of rods should be not less than the breaking strength of the parent material of rods, which is not less than the breaking strength of the parent material of rods. The load carrying capacity of the screw thread at the end of the rod should be not less than 75% of the breaking force of the mother material of the rod.

Applicable conditions of anchor rods

  1、According to the design requirements to determine the anchor hole position, use the eye drill, anchor drilling rig or coal electric drill to drill the eye, the depth is 80-100mm shorter than the length of the anchor.

  2、Extend the pressurized air pipe into the bottom of the eye, and blow the rock dust in the hole through compressed air.

  3、Diameter of drilling hole should be 6-12mm larger than the diameter of anchor rod.

  4、Feed the medicine roll into the bottom of the eye with the anchor, start the mixing device for mixing, and strictly control the mixing time according to the requirements of resin anchor fixing agent.

  5、After reaching the curing time, put on the tray and tighten the nut.
