Anchor bolt pre-embedding construction method

The invention discloses an anchor bolt pre-embedding construction method. The anchor bolt pre-embedding construction method comprises the following steps of mounting bottom bars; manufacturing at least two groups of bracket components, wherein each group of bracket components are longitudinally arranged and are fixedly connected with each other in the middles; mounting a lower-layer positioning frame: fixedly connecting the lower-layer positioning frame with each group of bracket components; fixing the bracket components: fixedly connecting the bottoms of the bracket components with the bottom bars; inserting anchor bolts: correspondingly inserting the multiple longitudinally-arranged anchor bolts into multiple mounting holes and fixedly connecting the anchor bolts with the lower-layer positioning frame; mounting an upper-layer positioning frame provided with a plurality of mounting holes corresponding to the lower-layer positioning frame: mounting the upper-layer positioning frame above the lower-layer posit
