Application Range Of Bolts

Note: 1. Conditional application means that the anchoring performance of the anchor bolt should not only meet the corresponding product standards and actual engineering requirements, but also have sufficient test basis, reliable structural measures and engineering experience, and be technically certified by a national designated institution license.

2. Bonded anchors, except for special cracked bonded anchors, generally bonded anchors are not suitable for the post-anchor connection of non-structural components with cracked concrete substrates.

3. c is the distance from the anchor bolt to the edge of the component, and hef is the effective buried depth of the anchor bolt. The anchor bolts used for the anchoring connection with seismic fortification requirements should use chemical planting, special cracking and bonding anchors, reaming anchors that can prevent the expansion of the expansion sheet, or torque control expansion anchors. Cone should not be used. Displacement control type expansion anchor with body separated from sleeve
