FIXING STRUCTURE OF POST-DRIVEN ANCHOR BOLT, AND FIXING METHOD OF POST-DRIVEN ANCHOR BOLT

摘要

PROBLEM TO BE SOLVED: To make a post-driven anchor bolt exhibit a stable resistive force against draw-out having a long life time without lowering the resistive force against draw-out of the post-driven anchor bolt with the lapse of time.;SOLUTION: A fixing structure of a post-driven anchor bolt is used to fix the anchor bolt 100 in a drilled hole in an existing base material. The anchor bolt has a linear shank 101 and a locking part 102 protruding in a direction perpendicular to the shank at a tip of the shank. The drilled hole includes: a first drilled part 21 opened in a surface of the base material; and a second drilled part 22 drilled in the deepest part of the first drilled part and having a cross section widely opened so that a step part 23 is formed between the first drilled part 21 and the second drilled part 22. The locking part is inserted into the first drilled part when the anchor bolt is fixed, and the locking part is latched to the step part when the locking part reaches the second drilled part.;COPYRIGHT: (C)2015,JPO&INPIT
