[0002]

BACKGROUND OF THE INVENTION Conventionally, there are various types of anchor bolts for generating and fixing frictional resistance between such perforations, and there are various types of anchor bolts. Of the three types.

[0003] First, as shown in FIG. 8, a core rod driving type anchor bolt 4 has a screw portion 41a in which a nut 40 is screwed into a head portion. And a tubular anchor body 41 having an axial slit 41s formed so as to form a plurality of lip portions 41b that can be opened at the lower end thereof, and is disposed so as to penetrate through the anchor body 41 and protrude upward therefrom. And a core rod 42.

In this installation work, first, a perforation 60 is opened on the concrete base surface 6 with a drill 8 or the like (FIG. 8).
(A)) The anchor body 41 penetrating the fastening portion 7 of the structure is embedded and held in a state where the anchor body 41 projects from the concrete base surface 6 for a predetermined length (FIG. 8B). Next, the head 42h of the core rod 42 is hit with a hammer 9 or a hammer to press the core rod 42 into the anchor main body 41 (FIG. 8C). The lip portion 41b is opened and expanded by this press-in force to bite into the inner wall of the perforation 60, and the anchor bolt 4 is fixed. Finally, the structure is fixed by tightening the nut 40 (FIG. 8D).

As shown in FIG. 9, a second type is called a sleeve driving type anchor bolt 5, and has a screw portion 51a for screwing a nut 50 to a head portion 51h.
Is formed, and a tapered bolt 51 whose lower end portion is tapered and expanded around the tapered bolt 51,
And a cylindrical sleeve 52 having an axial slit 52s formed so as to form a plurality of lip portions 52b that can be opened at the lower end.

[0006] This mounting work first, as described above,
A perforation 60 is opened on the concrete base surface 6 (FIG. 9).
(A)), and a sleeve 52 is added thereto with a predetermined length of concrete.
G and embedded and held together with the tapered bolt 51 in a state of protruding from the base surface 6 (FIG. 9B). Next, a socket 53 is attached to the upper end surface 52a of the sleeve 52, and its head is hit with a hammer 9 or a hammer to press-fit the sleeve 52 along the tapered bolt 51 (FIG. 9C).
