FB-47 SPLIT SET BOLT FEATURES1. What is Combi Plate and how does it make ? The tubular C shape of the bolt generates a load transfer from the steel to the rock when installed into a slightly smaller diameter hole, and results in a frictional resistance pull-out load of the tube from the hole, and creating a full length radial pressure to the hole by increasing the contact surface of the steel to the rock due to its tubular shape, and when install onto the plate, it establishes a compressive force against the rock. When additional load bearing capacity is required, friction bolt can be grouted by cement grouts.2. How to use and assemble ? A pull collar fixing at the ring end enables load testing during the bolt installation. The tapered end of friction bolt can be easily inserted into the drilled holes. Friction bolt can be installed with either hand held or mechanized equipment, such as a jackdrill, a stopper, a roof bolting jumbo, or any other type of drill.
