PURPOSE:To install easily a shearing displacement gauge by installing a case and a slide case so as to fix them, respectively, by using an anchor. CONSTITUTION:A displacement gauge of a distortion gauge type is contained in a slide case 2, and a case 1 is fixed to one fixed side, for instance, an old concrete surface. The case 1 is fixed by a fixing anchor 14 and a case fixing screw 15, and the slide case 2 is fixed by an anchor 17. Accordingly, when the side which abuts on a bearing and cantilever fixing jig 4 of a wedge 7 is adjusted to a position corresponding to a middle point of the bearing and cantilever fixing jig 4 and a contact 8, and the case 1 and the slide case 2 are positioned and fixed, a shearing displacement between new and old concretes can be measured in a prescribed range. |
