FRP Anchor Bar , FRP Anchor Bolt, Anchor Rod, Anchors Rod

FRP Anchor Bar Technical Specification:

FRP Anchor Bar is formed by glass fiber yarn, resin and curing agent after extrusion, pulling and high temperature curing. The shape of the bolt body is fully threaded, and the threads are left or right handed. It has high tensile strength, easy cutting, no damage to the teeth, no spark, safe coal mining, light weight, high corrosion resistance, flame retardant, antistatic performance, can be supported, is a new composite reinforcement material to replace metal bolt.

The product has been exported to the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other countries.

The common FRP bolt has a diameter of 16mm-32mm, and the supporting tray size is 125/140/150/170. FRP bolt length according to customer requirements, the length is generally 1400-2600mm; Thread with round head, generally 10mm pitch.

Technical parameters and torque of FRP bolt shall be greater than or equal to 40Nm

The main mechanical properties of FRP bolt include: tensile strength, shear strength, bearing capacity of tail joint and thread, torque. Specific test methods and standards are as follows:

1.Tensile strength test: the glass reinforced plastic anchor rod body to get rid of the anchor head and the anchor end, the middle period of intercepting proper length of a rod body, the determination of tensile strength on the material testing machine, testing machine according to tensile coefficient is the tensile strength of glass fiber reinforced plastic anchor rod, the unit is MPa, domestic FRP bolt tensile strength standard is not less than 300 MPa;

2, Shear strength test

3, the tail connection part and thread bearing capacity detection

4, anchoring force detection: rod body anchoring length 380mm±50mm under the condition, the anchoring force φ16 bolt in more than 50KN, φ18 bolt in more than 60KN, φ20 bolt in more than 70KN, φ22 bolt in more than 80KN, φ24 bolt in more than 90KN

5, torque detection: the FRP anchor rod body to remove the anchor head and tail, the middle section of the rod body interception of the appropriate length of a section, the rod body clamp, so that it can not rotate, torsional strength determination in the torque detection machine, torque unit is NM, according to the national MT/T1061-2008 standard thread bearing capacity in more than 40KN;

6, appearance detection: the appearance of the rod body should be uniform in texture, no burr, no bubbles, no cracks and other defects affecting the strength

7, torque regulation: bar physical torque should be greater than or equal to 40Nm

8, pallet bearing capacity: greater than or equal to 90KN

9, antistatic: resistance value is not greater than 3 X 10 8 times ω

10, flame retardant performance: 6 flame combustion does not exceed 30S, 1 flame combustion does not exceed 15s; The flameless combustion of six cables does not exceed 120 seconds, and the flameless combustion of one cable does not exceed 60 seconds

11, other parameters: the rod diameter deviation ±1mm, the rod length deviation ±10mm, the rod is not straight ≤3mm, the thread tail length ≥100mm
