| Zusammenfassung: | To provide a test piece fabrication method with which it is possible to 1) fabricate a test piece in a short time, 2) easily evaluate performance using a general-purpose tensile test machine, irrespective of the quality and shape of a concrete reinforcing member, and 3) reduce a variation in tensile test result for each test piece.SOLUTION: A test piece fabrication method pertaining to the present invention fabricates a test piece used in the tensile test of a concrete reinforcing member. The test piece fabrication method comprises a step for arranging metal pipe at both ends of a concrete reinforcing member, and a step for injecting a static demolition agent into a gap between the concrete reinforcing member and the metal pipe and curing the static demolition agent.SELECTED DRAWING: Figure 1
【課題】１）試験片を短時間で作製することができ、２）コンクリート補強部材の材質及び形状によらず、汎用的な引張試験機を用いて、容易に性能評価を行うことができ、３）試験片毎の引張試験結果のばらつきを小さくすることができる試験片の作製方法を提供する。【解決手段】本発明に係る試験片の作製方法は、コンクリート補強部材の引張試験に用いる試験片の作製方法であって、コンクリート補強部材の両端に金属管を配置する工程と、前記コンクリート補強部材と前記金属管との隙間に静的破砕剤を注入し、前記静的破砕剤を硬化する工程とを備える。【選択図】図１ |
