ANCHOR BOLT AND CONSTRUCTION METHOD FOR CONSTRUCTING ANCHOR BOLT BY SECURING DISPLACEMENT RIGIDITY OF ANCHOR BOLT WHEN OVERLAPPING ANCHOR BOLT CONSTRUCTION POSITION WITH STEEL REINFORCEMENT BAR IN CONCRETE

摘要

PURPOSE: An anchor bolt and a construction method thereof are provided to construct the anchor bolt without changing the construction position in spite of overlapping the anchor bolt on the steel reinforcement bar, and to secure the displacement rigidity of the anchor bolt. CONSTITUTION: An anchor bolt is composed of a first anchor bolt(2) having a laying part(3) shorter than the steel reinforcement bar covering margin, a second anchor bolt(7) having an axis deviated from an axis of the first anchor bolt, and a connecting member(5) integrally fixing the first anchor bolt with the second anchor bolt. When overlapping a first anchor hole on the steel reinforcement bar, a second anchor hole is perforated in the portion opposite to the alignment direction of the steel reinforcing bar to construct the anchor bolt.
