Abstract

PURPOSE: To facilitate cost reduction for anchor removal by linking a wire rod formed by twisting carbon fibers arranged on an anchor lengthy part of an anchor hole and a PC steel wire arranged on a free lengthy part of the anchor hole, together.
CONSTITUTION: A linking jig 2 is formed as large as possible to be inserted in an anchor hole, and hanging stop grooves are provided on its outer surface. A carbon fiber strand wire 1 is heated and processed in a U-turned shape, with its U-turned part hung and stopped with the hanging stop groove. A PC steel wire 3 is used for a free lengthy part, and is hung and stopped with the hanging stop groove in the same way as the carbon fiber strand wire 1. An anchor body constructed in this way is inserted into an anchor hole from both ends of the carbon fiber strand wire 1, and is situated at a predetermined anchor lengthy part. A mortar, etc., is cast there, and after it is hardened, the PC steel wire 3 and a PC steel wire 31 for linkage are strained, and an anchor head is fixed by a fixing tool such as a wedge. When the anchor body is to be withdrawn, the free lengthy part alone is withdrawn.
