It happens As described above, the lower part of the sleeve 12 opens and the slot 12b of the sleeve 12 opens and the projection 12a formed on the side surface of the sleeve 12 is in close contact with the anchor hole H so that the bolt 11 Is fixed to the anchor hole (H).

In the case of the conventional anchor bolt is configured as described above, because the separate equipment is used in assembling the sleeve in the lower portion of the bolt, not only the equipment cost increases due to the purchase of equipment, but also the assembly performance is reduced, resulting in a rise in manufacturing cost. In addition, the conventional anchor bolt still has a problem that the bolt is not securely fixed to the anchor hole because the bolt is fixed to the anchor hole by the tightening force of the screw.

The present invention was conceived by recognizing the above point is that the object of the present invention is not only fixed bolt securely to the anchor hole by driving the wedge nail, but also can screw the wedge nail into the bolt without using a separate tool bolt It is to provide an anchor bolt that is easy to fix the work.

The anchor bolt according to the present invention for the above purpose, in the anchor bolt is inserted into the anchor hole formed in the surface of the bottom, wall, etc. fixed, inserted into the anchor hole and the lower end is cut in the longitudinal direction split An anchor portion, a fastening portion formed with a male screw on an outer circumference of the upper end portion, and a stopper portion formed to protrude outwardly between the anchor portion and the fastening portion so as to be caught by the inlet edge of the anchor hole, and are extended in the downward direction from the upper end portion. And a wedge nail inserted into the wedge hole so that the anchor portion of the bolt is split and opened, and a nut screwed into the fastening portion of the bolt.

In addition, the anchor bolt according to the present invention is characterized in that the bolt is divided long in the longitudinal direction and the two divided bolts are joined to each other integrally coupled.

In addition, the anchor bolt according to the present invention is characterized in that the protrusions and grooves which are coupled to each other while being opposed to each other on the surfaces facing each other of the two divided bolts are formed.

The anchor bolt according to the present invention by the configuration as described above is not only fixed bolt securely to the anchor hole by driving the wedge nail, but also can work the wedge nail to the bolt without using a separate tool to fix the bolt It has an easy advantage.

Hereinafter, with reference to the embodiment shown in the drawings will be described in more detail the anchor bolt according to the present invention.

The present invention is inserted and fixed in the anchor hole (H) formed on the surface of the floor, wall (B) and the like, to fix the fixed object (F) in the fixed state.

Referring to the drawings the anchor bolt according to an embodiment of the present invention is composed of a bolt 100, a wedge 200 and a nut 300.

The bolt 100 is fixed while the anchor portion 110 formed in the lower end portion by the wedge nail 200 is sandwiched in the anchor hole (H). Referring to the drawings, the bolt 100 is composed of an anchor portion 110, a fastening portion 120, a stopper portion 130 and a wedge hole 140 is formed in the center.

The anchor portion 110 is a portion that is inserted into the anchor hole (H) while being fixed when the wedge nail (200) is inserted into the wedge hole (140) in the state inserted into the anchor hole (H). Referring to the drawings, the anchor portion 110 is inserted into the anchor hole (H) and the lower end is cut to split in the longitudinal direction to form an incision line (110a). The incision 110a is preferably formed as symmetrically as possible. When the wedge nail 200 is inserted into the wedge hole 140, the anchor portion 110 splits and opens at the incision line 110a.
