| 20110318134 | ANCHOR - The present invention is intended to provide an anchor that makes it possible to check the placement condition of the anchor easily to realize efficient and safe check after the placement. An anchor includes an expansion member that permits a shaft part to pass therethrough while being placed between a base portion of an anchor bolt and a spreading sleeve. The expansion member includes wing-like expansion parts that are caused to expand by pressing force exerted in the axial direction of the shaft part. The anchor bolt causes the shaft part to rotate in response to the rotation of the base portion of the anchor bolt, thereby driving a cone nut into the spreading sleeve. As a result, spreading parts spread outwardly. Further, the base portion of the anchor bolt presses the expansion member in response to threaded insertion of the shaft part to cause the wing-like expansion parts to expand. | 12-29-2011 |
