An anchor bolt for an adhesive anchor or the like that can be caused to exert substantial tensile strength at a relatively shallow embedding depth. An anchor bolt for an adhesive anchor that is fixed via adhesive to an anchor hole formed in a fixed body includes: a head part that is inserted into a hole back part of the anchor hole; a shank part that is continuous with the head part and formed to have a diameter smaller than the diameter of the head part; and a sleeve part into which the shank part is inserted, the sleeve part extending from an opening part to the hole back part of the anchor hole and having a tip end thereof abutted onto the head part.

An identification device of the present invention determines authenticity of an article with an anti-counterfeiting medium varying in a pattern of observed light depending on changes in light characteristics of radiated light, using the anti-counterfeiting medium. The identification device includes a similarity calculation unit that determines the degrees of similarity between a plurality of captured image data of the anti-counterfeiting medium obtained with differences in the light characteristics of the radiated light and reference image data corresponding to the light characteristics; and an authenticity determination unit that determines whether the degrees of similarity determined for the individual light characteristics exceed thresholds set corresponding to the individual light characteristics to make an authenticity determination on whether the anti-counterfeiting medium is genuine.

Identification device, identification method, identification program, and computer-readable medium including identification program

An identification device according to the present invention that performs authenticity determination of an article provided with an anti-counterfeiting medium whose observed light pattern changes depending on an observation angle includes a similarity calculating unit that calculates a degree of similarity between captured image data of the anti-counterfeiting medium and reference image data; an authenticity determination unit that performs authenticity determination as to whether the anti-counterfeiting medium is genuine or not on the basis of whether the degree of similarity exceeds a predetermined threshold or not; and a match-percentage notification unit that notifies a match-percentage indicative of a degree of match between an imaging viewpoint for imaging the anti-counterfeiting medium and a reference imaging viewpoint which is predefined as the imaging viewpoint for the captured image data used for authenticity determination.

To provide a method for forming an anchor hole and a diameter expansion device by which a centrifugal force can be appropriately adjusted when a cutting-blade portion is moved in a radial direction by the centrifugal force to grind a diameter expansion portion. In a method for forming an anchor hole for a post-installed anchor in which a diameter expansion drill bit is inserted and rotated in a prepared-hole portion bored in a concrete fixing body and a cutting-blade portion of the diameter expansion drill bit is moved in a radial direction by a centrifugal force to grind a part of the prepared-hole portion to form a diameter expansion portion, the minimum value of the centrifugal force applied to grind the diameter expansion portion is 0.75 N and preferably 1.1 N.

Method for forming anchor hole and diameter expansion device

A diameter expansion drill bit used to expand the diameter of a part of a prepared hole bored in a frame by grinding includes: a cutting-blade portion that has a plurality of separate cutting-blade portions; a cutting-blade holding portion that slidably holds the plurality of separate cutting-blade portions in a radial direction; and a shank portion that supports the cutting-blade holding portion. The plurality of separate cutting-blade portions is arranged in a peripheral direction and arranged over a plurality of stages in a shaft direction, and the plurality of separate cutting-blade portions of the respective stages is caused to slide by a centrifugal force resulting from rotation so as to spread to an outside in the radial direction with respect to the cutting-blade holding portion.

Diameter expansion drill bit

A diameter expansion drill bit used for inserting in a prepared hole perforated in a framework to expand a diameter of a portion of the prepared hole by grinding has a plurality of blade sections that grind the portion of the prepared hole, a blade holding section that holds the plurality of blade sections movably in a radial direction respectively, and a shank section that supports the blade holding section, and the plurality of blade sections move to spread outwardly in the radial direction with respect to the blade holding section by centrifugal force due to rotation.

A connection arm () of an injection nozzle () has an adhesive passage (). A nozzle outer cylinder () is supported by the connection arm () and has an intermediate passage () in communication with the adhesive passage () and a sealing member (). A nozzle inner cylinder () is elongated through the sealing member (), is slidably supported inside the nozzle outer cylinder (), and has a communication opening () communicating with the intermediate passage () as well as an adhesive discharge port (). An operation member () moves the nozzle inner cylinder () between an advanced position where the adhesive discharge port () lies deep inside a charging hole () and a receded position where the adhesive discharge port () lies shallow inside the charging hole () bored into a framework () to a predetermined depth through a finishing material ().
