Star Plate
The function of the star plate is to transfer the thrust generated by the locking moment of the nut to the top side, creating the initial anchoring force. At the same time, it transmits the pressure on the top side of the roadway to the anchor bolt, generating working resistance. Together, they reinforce the surrounding rock and prevent the displacement of the top side of the roadway.
