Rebar Full Model φ20

Reinforcing Bar

Reinforcing steel is a common construction material used in concrete structures to enhance their tensile properties. Reinforcing bars are usually made from hot rolled steel and have high strength and good ductility. Reinforcing bars are usually round or twisted ribbed in shape to increase their ability to bond with concrete. In building construction, rebar is welded, bent and fastened to specified locations to build structural elements such as concrete beams, columns and slabs.

When using reinforcing bars, it is necessary to select appropriate specifications and grades of reinforcing bars according to the design requirements and ensure that their quality meets the relevant standards. In addition, attention needs to be paid to the protection and antirust treatment of reinforcing bars during the construction process to ensure the durability and safety of the concrete structure.

Product Parameters

Product Details

Rebar anchors, are divided into longitudinal ribless rebar type resin anchors (left-handed anchors) and equal-strength rebar type resin anchors (right-handed anchors). They comply with MT146.2-2011 standard and are the basic components of coal mine roadway support, which are used in mines, engineering technology to support roadway perimeter rock, slopes, tunnels, dams, etc. for active reinforcement. As a tensile member deep into the ground, the anchor is connected to engineering structures at one end and deep into the ground at the other end, and is divided into a free section and an anchoring section, with the free section transmitting the tensile force to the anchored solid.

Resin anchor metal rod body advantages:

1, the strength of threaded section is greater than the strength of the rod body, and the threaded section has good bending and shearing resistance;

2、High strength of anchor, reasonable structure, large jacking force, able to automatically adjust the direction of force, increase the binding force on the rock, and can realize mechanized rapid installation;

3、Can be end anchor, extension anchor and full anchor, mainly used for high strength support of large deformation roadway in highland pressure mine.

Use method.

1. Determine the anchor hole position according to the design requirements, and drill the hole with drilling rig.

2.Blow out the rock dust in the hole with pressurized air.

3. Send the anchoring agent to the bottom of the hole, hold it against the anchor and start mixing (mixing time is specified according to the type of anchoring agent), after mixing, unload the mixing tool, and after the waiting time is reached, unload the mixing connecting head, put on the anchor plate, ball washer, friction washer, and tighten the nut with a wrench.

The development history of rebar anchors: 

  In recent years, China's left-handed anchor industry has adopted a two-legged approach. On the one hand, increase the strength of independent research and development, increase scientific research investment. On the other hand, the left-handed anchor enterprises to go out through overseas mergers and acquisitions in overseas acquisition of technology, equipment and markets.
