Suppliers Of Rebar For Sale

Product Description:

Left-handed anchor rods, for roadway support, are characterized by high strength, reasonable structure and large preload force. Left-handed anchor can increase the binding force on the surrounding rock, and the installation is mechanized, which is easier and faster. Lefty anchors can be end anchors, extension anchors and full anchors. According to the steel grade, the left-hand anchor is classified as MG335/MG500/MG600, and the diameter of the rod body is from 16mm to 22mm, which can also be processed according to the construction requirements.

Product Details：

Left-hand and right-hand anchors implement the MT146.2-2011 standard, which is the most basic component of tunnel support in contemporary coal mines, binding the surrounding rocks of the tunnel together and making the surrounding rocks support themselves. Nowadays, anchor rods are not only used in mines, but also used in engineering technology to actively reinforce slopes, tunnels and dams. Anchor as a deep stratum of the tensile member, it is connected with the engineering structures at one end, the other end of the deep stratum, the whole anchor is divided into the free section and anchorage section, the free section is the anchor head of the tensile force to the anchor solid area, its function is to apply prestressing force to the anchor; anchorage section refers to the cement paste will be prestressing tendon bonded with the soil layer of the region, its function is to increase the friction effect of the anchorage solid bonded with the soil layer, increase the anchor solid pressure-bearing effect, will be the anchor of the soil layer, and will be the anchor of the soil layer, the anchor of the soil layer. Its function is to increase the bonding friction between the anchor solid and the soil layer, increase the pressure-bearing effect of the anchor solid, and transmit the tension of the free section to the depth of the soil.

Longitudinal ribless threaded steel type resin anchor metal rod body use and installation:

1. Determine the anchor hole position according to the design requirements, and have the drilling machine to make holes.

2. Blow clean the rock powder in the hole with pressurized air.

3. Send the anchoring agent into the bottom of the hole, hold it against the anchor rod to start mixing (the mixing time is specified according to the model of the anchoring agent), after mixing, unload the mixing apparatus, and after reaching the waiting time, unload the mixing connecting head, install the anchor disk, ball washer, friction washer, nut, and tighten the nut with a special wrench.

Longitudinal ribless threaded steel type resin anchor metal rod body storage and transportation:

Resin anchor metal rod body is stored in a dry place, the anchoring section shall not be stained with oil, and the threaded section shall be protected against rust. Every 10 (or 5) rods as a group, bundled firmly, hanging a certificate of conformity. During transportation, the rod should be prevented from collision and nut falling off, and the rod should not be damaged or bent. During transportation, protective measures should be strengthened and stacked neatly.

Longitudinal ribless threaded steel type resin anchor metal rod body has the strength performance with accessories, the overall strength is greatly improved, the accessories supporting the use of mechanical integration to achieve the installation, resulting in a higher initial anchor force and other characteristics.
