ANCHOR, ANCHOR CONSTRUCTION TOOL AND ANCHOR CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an anchor that is improved in work efficiency when constructed, and thereby suppress the increase of construction cost.;SOLUTION: An anchor 1 includes a first screw part 3 formed in one end side of a shaft part 2, a second screw part 4 formed in the other end side of the shaft part 2, an engagement part 6 formed in the end of the second screw part 4 and protruded or recessed more narrowly than the diameter of the second screw part 4, and a nut 7 pre-installed to the second screw part 4. The anchor 1 is characterized in that the shaft part 2 and the nut 7 are integrally rotated and the first screw part 3 is screwed into a hole according to that an anchor construction tool 10 is rotated while the anchor construction tool 10 is engaged with both of the engagement part 6 and the nut 7, the engagement part 6 is disengaged from an engagement state with the anchor construction tool 10 when the first screw part 3 is screwed to the hole by a predetermined depth, and the nut 7 is rotated while the shaft part 2 is not rotated, and thereby is constructed in a state where the end surface of the nut 7 is joined and secured in a slab surface.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
