Claims

[Claims for Utility Model Registration] 1. Slits 2a, 2b, 9 shorter than the entire length of the locking tube 2 inserted into the mounting hole 1a of the concrete 1
c, 9d are formed in plurality so as to extend in the longitudinal direction from both ends of the locking tubes 2, 9, respectively, and the locking tubes 2, 9 are
a pair of diameter expanding members 3, which are inserted into both ends of the locking tubes 2, 9, respectively, and have tapered surfaces 3a, 4a, 7b, 7e, 8b, 8e on at least a portion of the locking tubes 2, 9; 4, 7, 8, an anchor bolt main body 5 that connects both the diameter expanding members 3, 4, 7, 8 to each other, and a nut 6 that is screwed onto the outer end of the anchor bolt main body 5. Anchor bolts for concrete featuring: 2. The anchor bolt for concrete according to claim 1, wherein a rough surface such as a spiral groove or sawtooth is formed on the outer peripheral surface of the locking tubes 2 and 9. 3. The concrete anchor bolt according to claim 1, wherein the diameter expanding members 3 and 4 have a truncated cone shape. 4. The diameter expanding members 7, 8 are cylindrical, and the outer circumferential surface thereof has tapered surfaces 7b, 8b and substantially wedge-shaped convex portions 7a, 8a integrally formed therein. Anchor bolts for concrete as described in Scope 1. 5 The diameter expanding members 7 and 8 have cylindrical tube portions 7c and 8.
The anchor bolt for concrete according to claim 1, wherein convex portions 7d and 8d, which are substantially wedge-shaped in plan and have tapered surfaces 7e and 8e, are integrally formed on one end of the concrete anchor bolt c.
