Factory Quality 20mm Rebar Bar

Product Description: 

Longitudinal ribless threaded steel resin anchor executes MT146.2-2011 standard. It is a kind of anchor made by special processing technology, the strength of threaded section is greater than the strength of the rod body, the threaded section has good performance of bending and shearing, it is a new type of anchor for high-strength support of shafts. The anchor has high strength, reasonable structure, large tightening force, can automatically adjust the direction of force, increase the binding force on the rock can realize the mechanization of rapid installation. It can be used as end anchor, extension anchor and full anchor, and is mainly used for high strength support of large deformation roadway in highland pressure mines. Application:Coal mine roadway support, but also for railroads, hydropower and other types of engineering high-strength permanent roadway support. Mining anchor is a kind of anchor commonly used in coal mine underground support and traditional metal anchor compared to its quality and solid full length and other strong length can be intercepted according to the specific needs of the rod body is easy to cut the operation is simple and convenient so that you do not make difficult to use so that the roadway and other construction sites are very favorable to the safety and construction.

Product Specification

Main use and application scope

MSGLW series of longitudinal ribless threaded steel resin anchors are mainly used for high strength support of large deformation roadways in high pressure mines, including full rock, coal and semi-coal roadways, and can also be used for high strength permanent roadway support of railroads, highways, hydropower and other projects.MSGLW series of longitudinal ribless threaded steel resin anchors are widely used in underground rocky roadways, semi-coal roadways and coal roadway support, and are especially suitable for the support of roadways and chambers under complex conditions in underground mines. It is especially suitable for the support of the tunnel and refuge under the complicated conditions in the underground.

Product Features:

The strength of the threaded section is greater than that of the rod body, and the threaded section has good bending and shearing resistance, which is suitable for high-strength support.

Reasonable structure, high jacking force, can automatically adjust the direction of force, increase the binding force on the rock, and can realize quick installation.

It can be used as end anchor, extension anchor and full anchor, and is mainly used for the support of large deformation roadway in highland pressure mines.

Wide range of applications, including coal mine roadway support, railroad, hydropower and other projects of high-strength permanent roadway support.

It is easy to operate, easy to cut, and the length can be intercepted according to specific needs, which is suitable for the support needs of various construction sites.

This product is suitable for underground support in coal mines, compared with traditional metal anchors, it is more stable and easy to operate, which helps to improve the construction efficiency and safety. If you have any further questions or needs, please feel free to contact me.

Precautions:

1. When using the drilling rig to make holes, please make sure to choose the proper drill bit and operation technique to avoid damaging the rock.

2. When using the pressurized air hose to blow clean the rock dust, make sure the ventilation is smooth to avoid breathing dust.

3. When mixing the anchoring agent, follow the specified time and method to ensure uniform mixing.

4. After removing the mixing apparatus, wait for enough cooling time to ensure the anchoring agent is fully solidified.

5. When assembling the anchor plate, ball washer and friction washer, pay attention to the order and position to ensure firm fixing.

6. When tightening nuts with special wrenches, control the torque appropriately to avoid over-tightening or over-loosening.

The above are some suggestions, hope it will help you when you use the anchor. If you have any questions or need further guidance, please feel free to let me know. I wish you good luck in your work!
