Features
Prestressed Anchorage refers to a permanent anchoring device used in prestressed concrete. It is an anchoring tool in a post-tensioned structure or component to maintain the tension of the prestressed tendon and transmit it to the interior of the concrete. It is also called a prestressed anchor.
Commonly used anchors for post-tensioning prestressed tendons:
1) The specific system of the upsetting anchor is to first pass the steel wire through the fixed-end anchor plate and the round hole in the tension anchor cup, and then use the heading device to head up both ends of the steel wire, and apply to prestress through the tension anchor. ;
2) The gang bar anchor is composed of a gang bar and a lining plate. The help bar adopts the same level of steel bar as the prestressed bar, and the lining plate adopts the steel plate of ordinary low-carbon steel. Evenly arranged, and perpendicular to the lining plate, the prestressed tendons welded firmly. Welding of the bar should also be carried out before the cold drawing of the steel bar, and the prestressed tendon should be prevented from being burned during welding.

General anchorage construction and installation methods
The general anchorage construction and installation method are to put a small number of explosives at the bottom of the hole, expand it into a spherical shape after several anchorage constructions and installations, and finally put the explosives into the anchorage construction and installation. Compared with the hole anchorage construction and installation method, this method has the advantages of good anchorage construction and installation effect, high work efficiency, fast progress, and low consumption of explosives. This method is often used in the construction and installation of short pile anchors for shallow foundations.
