The building structure 11 may be a column or a wall forming the skeleton of the building.

A set anchor or a wedge anchor may be used as the anchor 100 coupled to the building structure 11. However, in the present embodiment, a set anchor is used as the anchor 100. [ However, it does not exclude the use of wedge anchors and the like.

The set anchor 100 includes an anchor bolt 110 having a body portion 111 having a predetermined radius and formed at an end portion of the body portion 111 and having a conically shaped head portion 112, The anchor cap 120 is screwed to the body portion 111 of the anchor bolt 110 and the anchor bolt 110 is spirally moved in accordance with the tightening of the anchor bolt 110, And a tightening nut 130 for extending one end of the anchor cap 120 in the radial direction through a pressing action of the part 112.

At this time, the anchor bolt 110 and the anchor cap 120 may be formed of zinc-plated metal or stainless steel so as not to rust with strength.

A thread 111a is formed on the body 111 of the anchor bolt 110 and the head 112 is formed in a conical shape at an end of the body 111. [ The anchor bolt 110 thus formed is fitted into the anchor cap 120. The anchor cap 120 is formed with a cutout 121. Therefore, the end side of the anchor cap 120 on which the incision 121 is formed can be opened.

The tightening nut 130 is screwed to the body portion 111 of the anchor bolt 110 and the tightening nut 130 can be tightened along the thread 111a. When the tightening nut 130 is tightened, the anchor cap 120 (120) formed by the pressing action of the bulged head 112 of the anchor bolt 110, which is conveyed by the tightening action of the tightening nut 130, ).
