The embedded quality of anchor bolts directly affects the installation quality of steel structure. It is of great significance to control the position, perpendicularity, length and elevation of anchor bolts (Group) to reduce the reaming and adjustment workload (or even avoid rework) and improve the quality of structural installation. The embedded method of anchor bolt can be direct embedded method or reserved hole method.
