摘要

PURPOSE: To make an anchor attachable to a concrete panel at a factory by enabling loads concentrated on the concrete panel to be dispersed by means of a wide anchor, enhancing the efficiency of the work of attaching the anchor to the concrete panel, and preventing the anchor from falling off the concrete panel during transportation. ;CONSTITUTION: A blind hole 32 is bored through the reverse side of a concrete panel 3 in advance and an attaching device 2 is installed at the end portion of the panel 3 and a blind hole 31 for crossing the blind hole 32 is bored through the butt end face 30 of the panel 3, and a strip flat anchor 1 having a cutting edge portion 12 at its end and being greater in width than the blind hole 31 is pressed into the blind hole 31 and a male screw 14 attached to approximately the center portion of the anchor 1 is directed toward the blind hole 32. After the anchor 1 has been pressed in, a thumbscrew 18 for connecting the concrete panel 3 to the structural body of a building is threadably fitted around the tapped portion of the male screw portion 14.;COPYRIGHT: (C)1994,JPO&Japio
