1. According to the engineering design requirements, drill holes in the corresponding position in the base material (such as concrete), and the hole diameter, hole depth and bolt diameter should be determined by professional and technical personnel or field tests.
2. Drill with percussion drill or rhinestone.
3. Clean the dust in the borehole with a special air cylinder, brush or compressed air machine, it is recommended to repeat it no less than 3 times, and there should be no dust and open water in the hole.
4. Ensure that the surface of the bolt is clean, dry and oil-free.
5. Confirm that the glass tube anchor package has no abnormal phenomena such as appearance damage and coagulation, and put its round head inward into the anchor hole and push it to the bottom of the hole.
6. Use an electric drill and a special installation fixture to rotate the screw and insert it until the bottom of the hole, and the impact method should not be used.
7. When it is screwed to the bottom of the hole or the marked position on the bolt, stop the rotation immediately, remove the mounting fixture, and avoid disturbance after gelling until it is completely cured. Overtime rotation leads to glue loss, affecting anchoring force. (The rotation time should not exceed 30 seconds, the rotation speed should not be less than 300 rpm, not more than 750 rpm, the bolt advance speed should be about 2cm/s, and the impact method is not allowed.) )
