First check Wedge anchor for concrete supplier whether the installation meets the requirements and whether there are any loose bolts
Loosening of Expansion Wedge Anchors after installation may be caused by improper installation or material quality problems. Therefore, for expansion bolts that have become loose, you should first check whether the installation meets the requirements and whether there is any loosening of the bolts. If any problems are found, they should be corrected in time.
Ensure that the expansion bolts are securely fastened
Before installing expansion bolts, you must make adequate preparations. First, you must select the appropriate expansion bolt specifications to ensure that its bearing capacity and use requirements meet the actual situation. Secondly, you must clean the holes of the expansion bolts to ensure that there is no dust, cement residue or other debris in the holes to ensure the stability of the bolts during installation.
After the expansion bolts are installed, they should be pre-tightened and locked as necessary. Pre-tightening means that after the expansion bolts are installed, the nuts should be rotated appropriately to form a pre-tightened state with the bolt heads, and the final locking should be performed after the concrete hardens. The locking needs to be controlled by a torque wrench to ensure that the expansion bolts are securely tightened.
