Metal Rebar

Metal rebar, a structural support material commonly used in construction and civil engineering. Its characteristics include:

1. High strength: it has good tensile and compressive strength, and can effectively withstand the load of the building structure.

2. Good ductility: capable of plastic deformation to a certain extent, which enhances the toughness of the structure.

3. Corrosion resistance: the surface is usually treated or plated to resist most corrosive media.

4. Easy construction: regular shape, easy to cut and connect, can meet the needs of different projects.

5. Recyclable: metal reinforcement bars can be recycled and reused, reducing resource consumption.

Product Parameters 

The metal body of resin anchor without longitudinal rib threaded steel type has the following advantages:

1. The strength of the threaded part is greater than the strength of the rod body, which makes the anchor have good resistance to bending and shear force;

2. High strength of anchor rod, reasonable design structure, able to withstand larger jacking force, automatically adjust the direction of force, increase the binding force on the rock, and facilitate rapid mechanized installation;

3. It can be used for end anchoring, length extension anchoring and complete anchoring, especially suitable for high strength support needs in high ground pressure mines with large deformation roadway.

Product Use and Characteristics:

MSGLW series of longitudinal ribless rebar type resin anchor metal rod body products are mainly used for anchor support of underground rocky tunnel, semi-coal rocky tunnel and coal tunnel, especially suitable for the support of tunnel and refuge under complex conditions underground. This product is used together with resin anchors and has the following characteristics:

1. Rapid growth and high strength: After installation, the product rapidly increases its strength and has a high load-bearing capacity, which ensures a solid anchoring force.

2. Easy installation: convenient operation, reducing labor intensity of workers and improving support efficiency.

3. Reduce the cost of supporting tons of coal: effectively reduce the cost of supporting, economical.

This product plays an important role in the support project of underground rocky tunnel and coal mine tunnel, providing reliable support guarantee for the project construction.

Working principle of metal rod body of resin anchor without longitudinal rib threaded steel type:

1. Determine the anchoring length according to the design requirements, insert the rod body into the pre-prepared anchoring agent hole.

2. Stir the resin anchoring agent evenly and pour it into the hole. The anchoring agent will have a chemical reaction within a certain period of time, bonding the rod body and the rock into one.

3. Install the protection net and load tray at the threaded end of the rod, and tighten the nut to achieve the support function. Through the above steps, the metal rod body of the longitudinal ribless threaded steel type resin anchor can form a high-strength prestressing support, which can be firmly fixed in the rock wall, control the stability of the roof slab, adapt to the movement of the peripheral rock, reduce or eliminate the problem of delamination, and prevent the roof slab from collapsing. This support system consists of a variety of support forms and structures, realizes mechanized installation, and significantly improves the safety and reliability of the support project.

Product Description Production Process.

Left-handed non-longitudinal ribbed threaded steel type resin anchors are manufactured with advanced production technology. This kind of anchor has high strength, reasonable structure, large preload force, and can automatically adjust the direction of force, thus increasing the binding force on the surrounding rock. In addition, it is capable of rapid mechanized installation.

The steps of metal rod body of MSGLW-500 longitudinal ribless threaded steel type resin anchor are as follows:

1. Determine the position of anchor rods according to the design requirements and drill holes using drilling rigs.

2. Use the pressurized wind equipment to clean the rock chips and dust in the hole.

3. inject the anchoring agent into the bottom of the hole, then hold it against the anchor rod and start mixing (the mixing time should be specified according to the anchoring agent), after the mixing is completed, unload the mixing equipment, wait for a certain period of time, unload the mixing connecting head, install the anchor disk, spherical washer, friction washer, nut, and finally tighten the nut using the special wrench.
