Anchor bolts

Abstract

This product is used in post-installed anchoring methods in which one flange portion and part of the bolt portion are inserted into anchoring holes drilled in concrete structures such as culverts, dam bodies, and buildings, or in bedrock, and are embedded in the fixing material filled into the anchoring hole, while the other part of the bolt portion is exposed from the anchoring hole, and is fixed in the anchoring hole by hardening the fixing material. Before use, the four expansion wings of this product are bent as shown in the "Reference Perspective View," but after use, as shown in the "Reference Perspective View Showing the State After Use," the four expansion wings extend so that they expand and fit into the groove carved into the periphery of the wall surface of the anchoring hole.
