THREADED REBAR-RESIN BOLT

• USED IN MAIN OPENINGS TO INCREASE LOAD-BEARING

CAPACITY IN JOINTED ROCK FOR LONG TERM PURPOSES.

THIS BOLT UTILIZES THE RESIN TO CREATE

ANCHORAGE BETWEEN THE ROCK AND THE BOLT.

Technical Data 3/4" - 10 UNCLength: 6’

Yield Strength, min. 20,000 lb (89 kN)Tensile Strength, min.

30,100 lb (133.9 kN)

Elongation in 8" (200mm)

9% minimum

FORGED HEAD RESIN BOLT

AS THE FORGED HEAD BOLT IS SPUN BY THE DRIVER, IT

MIXES THE TWO COMPONENTS OF THE RESIN

IN THE HOLE. THE RESIN IMMEDIATELY BEGINS TO SET,

THIS ACTS AS A MODE OF ANCHORAGE TO BOND THE

ROCK AND THE BOLT.

MECHANICAL ANCHOR BOLTS PROVIDE AN IMMEDIATE LOAD-BEARING CAPACITY

WITH AN OPTIMIZED RATIO OF ANCHOR FORCE AND

HOLE DIAMETER. THE SHELL EXPANDS AS YOU DRIVE THE BOLT INSIDE THE HOLE, THIS PROVIDES A GRIP AGAINST THE ROCK THUS PROVIDE

TENSION ON THE BOLT.

DYWIDAG THREADBAR- RESIN BOLT

UNLIKE A FORGED HEAD , THIS THREADBAR USES A LOOSE TENSION NUT TO

TENSION THE BOLT. USED IN MAIN DRIFT FOR LONG TERM

SUPPORT.
