Advantage of Bidirectional expansion anchor bolt:

1. The anchor bolt will be anchored in two directions with excellent aseismatic performance and high security;

2. The two expansion directions of the dilatant positions are adverse, which may offset the expansion strain and result in small edge distance for anchoring;

3. In comparison with chemical anchor bolt: Upon the completion of installation, the anchor bolt can immediately bear maximum design load without waiting;

4. It's unnecessary to drill additional holes when replacing with new anchor parts. Rotate the screw of the anchor bolt to remove it and replace with new anchor parts. Then re-install and fasten the removed screw.
