<P>PROBLEM TO BE SOLVED: To provide a driving jig capable of suppressing a burden on a worker to the utmost when a driving type anchor is attached to a wall surface material for a civil engineering structure. <P>SOLUTION: A provided driving jig 28 includes a columnar body portion 42, a slit 45 that is formed in the columnar body portion 42 throughout its axial-elongation-direction length, an overhanging portion 43 that overhangs sideward from an outer peripheral surface of the columnar body portion 42, and a connecting shaft portion 44 that is attached to the overhanging portion 43 in such a manner as to get away from the slit 45. The driving jig 28 is attached to an electric hammer, and one end of a shaft-like portion 7 of an anchor 3 and a driving cylinder 24 are inserted into an attachment hole 4 of a natural stone 2. Subsequently, the shaft-like portion 7 of the anchor 3 is put into the slit 45 of the driving jig 28. The electric hammer is operated, and a striking force (pushing force) of the electric hammer acts on the other end surface of a locking cylinder 24 via the connecting shaft portion 44, the overhanging portion 43 and the columnar body portion 42. <P>COPYRIGHT: (C)2012,JPO&INPIT |
