Prestressed anchor bolt mounting structure

According to the prestressed anchor bolt installation structure, the first through hole is formed in the lower anchor plate, then the threaded sleeve is installed on the lower anchor plate through the bottom bolt, and the threaded sleeve can be connected with the anchor bolt at the same time. In addition, the situation that in the prior art, when anchor bolts are connected on a lower anchor plate in a welding mode, damage is caused to the lower anchor plate, and then adverse effects are caused to the overall structure can be avoided. And meanwhile, by arranging the threaded sleeve, concrete can be prevented from entering the first through hole of the lower anchor plate, and therefore sealing treatment does not need to be conducted on gaps during concrete pouring. More importantly, as the threaded sleeve completely enters the concrete after being poured, the bottom bolt is as strong as the anchor bolt at the moment, so that the broken position of the anchor bolt is ensured to be in the threaded sleeve or above
