る拡径孔用アンカーボルト。 Around the anchor bolt body, which has a male thread carved into the base end and a tapered overhanging jaw whose outer diameter gradually increases toward the tip, there is a notch groove extending from the tip periphery at an appropriate point toward the base end. The opened sleeve is loosely mounted, and a nut screwed onto the male thread is tightened to press the sleeve toward the tip of the bolt body, thereby expanding the diameter of the sleeve tip along the projecting jaw. In the anchor bolt, at least one groove is formed around the bolt body between the sleeve tip and the overhanging jaw, the wall thickness of which is gradually thickened from the base end to the tip, and a notch groove is formed from an appropriate position on the tip periphery toward the base end. An anchor bolt for expanded diameter holes characterized by a loosely fitted auxiliary sleeve.
