Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone net fixing apparatus,

The present invention relates to a stone net fixing apparatus and a method of constructing a stone net using the same, and more particularly, to a stone net fixing apparatus capable of maintaining a firm and stable fixed state for a long time even after being installed in a stone net, .

As urbanization and industrialization have progressed rapidly in recent years, there is a growing need for land use in river basins. As a result, there is an increasing need for land use around the river for various purposes such as the purpose of dimension to prevent flood, The slope protection construction is being implemented.

In general, the slope protection work for slope protection is mainly used to block the entire slope of the river with concrete by using artificial concrete structure. However, this method is a main cause of environmental destruction and has a limitation in using have.

Therefore, in recent years, a method of constructing a stone net on a slope using stone has been used for solving the problems caused by the concrete block method.

The stone net is formed by fixing a plurality of stones to an upper portion of a metal net using an anchor bolt and a fixing washer. The stone is made of natural stone or artificial stone, and a nonwoven fabric is installed on the top of the net. After the stone net is fixed by fixing the stone to the metal net in this manner, the manufactured stone net is unfolded on the slope.

However, in the conventional stone net, since the fixed washer fixed on the net is formed in a straight shape, the contact area between the net and the net is so small that the adhesion is reduced and the stone is rotated at any time, there was.

In addition, if the fixing force of the fixed washer is weakened, the stone may be separated from the net when the stone net attached with the stone is moved, which may cause a great inconvenience to reinforce the surface using the stone net.

As an example of the technique for solving such a problem, a stone net assembly for use in a stonewall for protecting the surface of a court is disclosed in Patent Publication No. 10-1002132.

The stone net assembly used for the above-mentioned surface protection stone net is a cruciform washer which is closely attached to the other surface of a net wire net, has a through hole at its center, and has serration- A fixture inserted into the insertion hole formed in the natural stone through the through hole of the cruciform fixing washer to fix the netting wire mesh to the natural stone together with the cruciform fixing washer; A plurality of sharp protrusions formed on the surface of the cruciform fixing washer in close contact with the netting wire mesh, and a straight mesh groove formed in the surface of the cruciform fixing washer in close contact with the netting netting mesh to insert the netting of the netting wire mesh.

In the conventional technique configured as described above, since the cross-shaped fixing washer provided for fixing the natural stone to the mesh net is not rotated by the serrated projections or sharp projections, the fixation force for fixing the natural stone to the mesh net can be maintained .

However, in the conventional art having the above-described structure, the fixing washer can not be firmly fixed to the net, but only the fixing force of the fixing washer for fixing the stone to the net is maintained. So that the shape of the fixed washer and the net is easily deformed, thereby loosening the anchor bolt's binding force.
