Referring to FIG. 1, a binding member 10, a fixing nut 20 and a bolt 30 are included.

First, the bolt 30 is fixed to a wall (not shown) and has a horizontally elongated structure.

The wall may be constructed using a blasting stone, a natural stone, or a block as will be described later.

When the wall is composed of a blast stone and a natural stone, the bolt 30 is formed on the set anchor, and the bolt 30 can be fixed to the wall as the set anchor is installed on the wall. And can be coupled to the wall. In this case, the set anchor can be installed by a method in which the anchor is partly inserted into the blast stone and the natural stone and fixed using a fixing agent or the like. The bolt 30 is fixed to the end of the set anchor exposed from the blasting stone and the natural stone.

The set anchor can be illustrated as shown in FIG. 2 illustrates that the bolts 30 are formed at the ends of the blasting stone and the set anchor 32 installed in the natural stone.

Alternatively, when the wall is formed of a block, a part of the bolt 30 is inserted into the groove formed in the block, and the end of the bolt 30 inserted in the block can be fixed by a fixing agent filling the groove. As the bolt 30, a computer bolt may be used as an example.

Here, the block is formed by processing stone or using concrete and can be understood as a unit for forming a wall. An example of the above-mentioned block will be described later.

The fixing nut 20 is positioned between the end of the bolt 30 and the coupling aperture 10 and is screwed with the bolt 30 and blocks the coupling aperture 10 from moving to the end of the bolt 30. [ The fixing nut 20 may be configured to have various shapes and lengths that can be screwed with the bolts 30. [ Illustratively, the locking nut 20 may be constructed using a hexagonal nut.
