Abstract
PURPOSE: To prevent the production of shear droop at the edge of an insertion prepared hole, by a method wherein, in a method to process a PC steel wire anchoring hole formed in a anchoring plate for the head of a numeral 8-shaped PC steel wire, the prepared hole, formed as a PC wire insertion hole, is previously provided.
CONSTITUTION: In a numeral 8-shaped PC steel wire head anchoring plate 1 called a coupling pile, for processing an anchoring hole, a preliminary hole for a tap hole 2 is first processed in the anchoring plate 2, and a concical disposal hole 3 is formed in the proximity of the tap hole 2. A hole 4 is deep-drawn from the upper surface of the prepared hole 3 to form a seat for the head of the PC steel wire. When said hole 4 is deep-drawn, a projection 5, simultaneously, is formed on the back of the anchoring plate 1. A numeral 8-shaped hole 6 is then formed by means of a numeral 8-shaped hole punch and guide pin, and simultaneously, the prepared holes 2 and 3 for a tap are completed as the tap the hole and the PC steel wire insertion hole. The tap hole is then tap-processed.
