FRP Bolts and Nuts Washer for Industry High strength FRP rock bolt for construction

Introduction of frp rebar

 Fiberglass / FRP/ GRP bolts and nuts using high-strength fiberglass impregnated epoxy resin matrix at high temperature pultrusion. After CNC process, grinding, special surface treatment made of insulated bolts and nuts.

 Fiberglass Rebar adopt glass fiber as reinforced materials and  polyester resin as basic materials, through Pulled by specific traction machine, be solidified glass fiber reinforced plastic rod body with full thread under high pressure and high temperature by preformed matched die . It is made up of fiberglass anchor rod plus resin anchoring agent, tray and nut.
 Bolts and nuts have a special treatment by the surface, so that the bolts and nuts have good flexibility, excellent wear resistance, excellent resistance to voltage performance. Products applicable to transformers, reactors, special high-voltage converter valve, and other special high-voltage electrical appliances.

Rock Bolts
  Pultruded Rock bolt comes with a surface roughened by helical winding or textured surface for enhanced shear bonding between the grout and the rod with high-pressure injection moulded thread and composite nut.

Advantages of FRP rebar
1.High strength and impact toughness

2.Non-Corrosive 

3.Non-Conductive 

4.Dimensionally-Stable-Under-Thermal-Loading 

5.Outstanding anchorage capability.

6.Excellent performance in high deformation ribs

7.Installed with standard techniques and equipment.

8.Easily handled and transported.

9.Fire resistant and anti-static rating.

10.Cutability without the danger of sparks.

Specification of frp rebar

Method of application for FRP rock bolt

After the roofbolter finished drilling, remove the drill pipe, make the six-party of rock bolt installation machine insert jumbolter drill pipe connection, then make the lever genus part of compression nut insert the rock bolt installation machine, make anchoring agent into the rock bolt holes, then use the rock bolt bracing anchoring agent, at this time do propulsion leg movement, drilling machine motor not rotating, anchoring agent will be sent to the bottom of the hole, at this point to start drilling machine motor rotating, rotating rock bolt to stir anchoring agent, when the FRP rock bolt reached the bottom of the hole, stop the machine, drilling machine fast rotating to stirring anchoring agent, stirring time is set time of anchoring agent (usually 10 s ~ 15 s ), close the drilling machine, stop rotating, according to the anchoring agent curing time, general stop 30 s ~ 45 s, after anchoring agent curing, ant then make drilling machine to start rotating, screw up the nut for bottom of rock bolt, at this time drilling machine motor stop rotating, rock bolt install end.
