<P>PROBLEM TO BE SOLVED: To provide a checking gauge for a drilled hole of a hole-in anchor, capable of easily and surely checking compatibility of the drilled hole uniquely by forming the checking gauge with a drilled hole dimension adapted to the hole-in anchor to be used, capable of checking the depth dimension and hole diameter of the drilled hole simultaneously, serving formation of the drilled hole without an error, and capable of securing a prescribed anchor performance. <P>SOLUTION: A checking gauge for a drilled hole of a hole-in anchor is formed in a belt-like shape gradually widened from a front end 2a to be inserted into the drilled hole to a base end 2b. One side edge in the width direction of the checking gauge is formed as a linear vertical side 2c along the depth direction of the drilling hole, and the other side edge in the width direction is formed as a hypotenuse 2d having an appropriate inclination with respect to the vertical side. A mark line X is provided perpendicularly to the vertical side at a position of the depth dimension E adapted to the hole-in anchor to be used, measured from the front end along the vertical side, and a width dimension from the vertical side to the hypotenuse at the position provided with the mark line is set to a hole diameter dimension D adapted to the hole-in anchor to be used, measured from the vertical side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
