[0002] In the process of equipment installation, anchor bolts are often used. There are basically two ways to install anchor bolts, one is the reserved hole method, and the other is the direct embedding method. When using the direct embedding method, when fixing the cast anchor bolts, the number of bolts is small and the distance is close. The installer will punch holes in the box plate according to the requirements of the drawing, and then fix the bolts and reinforce them. However, if the area where the anchor bolts are installed is large and the distance between the bolts is far, the above method cannot be used. In some cases, the equipment needs to be installed with high precision and regardless of cost. It can be processed into two large flanges, then cut into several pieces, and spliced ​​and welded on site. The accuracy can generally be guaranteed to be within 2mm, but the cost is high, the on-site centering is more complicated, and it is even more inconvenient if multiple sizes of anchor bolts need to be installed. In order to be able to accurately and cost-effectively complete the alignment and positioning of the anchor bolts before civil engineering pouring, it is very necessary to design tools for aligning and positioning the anchor bolts before civil engineering pouring.
