The distance from the center of the anchor bolt to the edge of the foundation should not be less than 2d (d is the diameter of anchor bolt) and not less than 15mm (d ≤ 20 should not be less than 10mm), and not less than half of the width of the anchor plate plus 50mm, when the above requirements cannot be met, appropriate measures should be taken to strengthen. The diameter of anchor bolt for structure should not be less than 20mm, and when it is subjected to seismic action, it should be fixed with double nuts or other effective measures to prevent loosening, but the anchor bolt anchorage length should be increased by 5d compared with the non-seismic anchorage length.

The installation of the anchor bolt should meet the following requirements: the distance from the center of the bolt to the edge of the foundation is not less than 7 times the diameter of the anchor bolt; the strength of the foundation where the anchor bolt is installed should not be less than 10MPa; there should be no cracks in the drill hole, and attention should be paid to prevent the drill bit from colliding with the reinforcement and buried pipe in the foundation; the diameter and depth of the drill hole should be matched with the anchor bolt. anchor bolt match.

4、Bonding anchor bolt is a kind of anchor bolt commonly used in recent years, its method and requirements are the same as the expansion anchor bolt, but when bonding pay attention to the hole debris blowing clean, and shall not be subject to moisture.
