Title:
AUXILIARY TOOL FOR ATTACHING ANCHOR BOLT
Document Type and Number:
Japanese Patent JP2013224711
Kind Code:
A
Abstract:

To provide an inexpensive anchor bolt that is attachable/detachable several times and reduces stress of a mating material.

A body 10 is inserted into a through-hole of an mating material with its bottom end 20 being the lead as far as its flange 30 is brought into tight contact with the surface of the mating material. An anchor bolt is screwed into an opening 40 by a thread of the anchor bolt without a thread tapped in the opening 40. When the anchor bolt is inserted, the thickness of the body 10 around the anchor bolt is reduced by tension and the diameter of the body 10 is enlarged. Because the body 10, the flange 30 and the bottom end 20 are made of a material having a hardness in the range of 50 or more and 90 or less, the body 10 cuts into the uneven inner peripheral surface of the through-hole of the mating material and thus the outer peripheral surface of the body 10 is brought into tight contact with the inner peripheral surface of the through-hole of the mating material. At the same time, the diameter of the bottom end 20 is enlarged to its maximum larger than that of the through-hole of the mating material. The flange 30 and the bottom end 20 enlarged to its maximum are fastened to the topside and underside of the mating material respectively.
