When installing the anchor bolts, the first step is to first find the position of the top of the anchor bolts. The error range is between three and four millimeters, which must be within this range. Wait until the initial verticality is determined to fix the tie bars or the adjustable steel bars. After doing the above, fix the anchor bolts one by one. Finally, the second correction is made so that the error control range of the top of the anchor bolt is within two millimeters, so that the nut of the matching anchor bolt above and below the fixed frame steel plate is simultaneously tightened. Wait until all the anchor bolts have been calibrated and fixed, and then conduct a comprehensive inspection. If the individual does not meet the requirements, correct them in time. Finally, check the axis once, and after confirming that it is correct, you can pour concrete.
