(57) [summary] [challenge] upon the thickness of the test, such as a wall of the pavement or the building of the road, easily I want to be able to efficiently measure the thickness of the core cut out from the pavement or wall. To A on the base 1, a surface plate 6 Post a core A is horizontally rotatably supported, and removably attaching a ruler unit 21 on this surface plate 6. The ruler unit 21, cores A It has a four ruler 22 located around the. These ruler 22 The indicator 27 each are supported to slide up and down. Rely on these directives 27 on the top surface of the core A, core A in four locations The thickness I measure of. For the more detachable ruler unit 21 is to facilitate the loading and unloading of the core A. By surface plate 6 is rotatable, easily read the scale of the four ruler 22 from one place.
