Self Drilling Anchor Bolt Systems
Self drilling anchor bolt system is composed of hollow anchor bar, coupler, nut, drill bit, plate, and cen- tralizer. It can combine drilling, grouting and anchoring in one process. The Self-Drilling Hollow Bar Anchor System is comprised of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring and grouting in a single operation. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. Grout fills the hollow bar and completely covers the entire bolt. Couplers can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension.
