Definitions
- Anchoring bolts 13 are inserted into the holes to fix the anchoring plate 11.
- a gap between the anchoring plate 11 and the concrete is filled with epoxy and anchoring devices 14 and 15 are installed and a steel wire 17 is tensioned.
- an anchoring plate 51 is manufactured and holes for installing anchor bolts 53 are made in a PS concrete girder as shown in FIG. 5.
- a steel rod 53' to be installed midway of the girder can be installed when there exists a hole already in the existing girder, and since it is nearly impossible to make a new hole, there are not many cases of installing the steel rod 53.
- the anchoring plate 51 and an end plate 59 are fixed and welded.
- anchoring devices 54 and 55 are installed and a steel wire 57 in a steel wire pipe 56 is tensioned.
- At least one or more rib plates 60 can be installed to be perpendicular to an anchoring plate 61.
- the rib plate 60 is welded to the anchoring plate 61 and the end plate 69 so that the length of the welding portion receiving load can be increased remarkably.
- the anchoring method and apparatus of an end bearing support type in external prestress reinforcement adopts an improved end bearing support type and used for reinforcement of a bridge or a pier. Particularly, installation is easy, damage to existing bridge and pier is minimized, and a reinforcement work is possible in a small place.
