[V-611] Evaluation test of anchor bolt with thread rolling of the same diameter as deformed rebar

Keywords:anchor bolt, rolled thread, bridge falling prevention structure

The anchor bolts we developed are machined so that the anchor rebar and the threaded part have the same diameter. Because the diameter is larger than that of a general cutting thread, the cross-sectional area can be increased. Therefore, various merits occur in both design and construction.However, since thease screw thread diameter are not described in JIS, tensile tests and shear tests were conducted to confirm mechanical performance. As a result, it was confirmed that these had sufficient performance.
