Grid fixing apparatus having spacer-integrated retaining clip for grid reinforcement and grid fixing method using the same

A grid fixing method using a grid fixing apparatus including a spacer-integrated retaining clip, which is a grid fixing method using a grid fixing apparatus for grid reinforcement of an object, the grid fixing method comprising:

• a) mounting a grid reinforcement material comprising a lattice structure in close contact with the object subject to grid reinforcement;
• b) mounting a spacer and a retaining clip of a grid fixing apparatus on the grid reinforcement material;
• and
• c) passing an anchor pin of the grid fixing apparatus through the retaining clip and the spacer to tack the anchor pin of the grid fixing apparatus into the object,
• wherein the object is concrete, an outer wall body, or a pavement base layer, and
• the grid reinforcement material is fixed in vertical and horizontal directions by the retaining clip in a state in which the grid reinforcement material maintains a predetermined distance from the object by the spacer so that the grid reinforcement material is precisely constructed on the object,
• wherein the grid fixing apparatus comprises:
• the retaining clip which has a first through-hole formed in a central portion and comes in direct contact with the lattice structure of the grid reinforcement material so that the grid reinforcement material is fixed;
• the spacer which has a second through-hole corresponding to the first through-hole formed therein and which is integrally formed with a lower surface of the retaining clip so that the retaining clip maintains a predetermined distance from the object, and the spacer has a length corresponding to a diameter of the grid reinforcement material;
• and
• the anchor pin which is tacked using a tacker or tacking device and passes through the first through-hole formed in the retaining clip and the second through-hole formed in the spacer to be tacked into the object.

A grid fixing method using a grid fixing apparatus including a spacer-integrated retaining clip, which is a grid fixing method using a grid fixing apparatus for grid reinforcement of an object, the grid fixing method comprising:

• a) mounting a grid reinforcement material comprising a lattice structure on the object subject to grid reinforcement so that the grid reinforcement material is spaced apart therefrom;
• b) mounting a first spacer and a first retaining clip of a grid fixing apparatus on a lower portion of the grid reinforcement material that faces toward the object;
• c) forming a second spacer and a second retaining clip on an upper portion of the grid reinforcement material that is above the first spacer and the first retaining clip in a direction away from the object and inserting and fixing the grid reinforcement material between the first retaining clip and the second retaining clip;
• d) passing an anchor pin of the grid fixing apparatus through the second retaining clip, the second spacer, the first retaining clip, and the first spacer to tack the anchor pin of the grid fixing apparatus into the object;
• and
• e) constructing a binder on an entire surface of the grid reinforcement material,
• wherein the grid reinforcement material is fixed in vertical and horizontal directions by the first retaining clip and the second retaining clip in a state in which the grid reinforcement material maintains a predetermined distance from the object by the first spacer so that the grid reinforcement material is precisely constructed on the object,
• wherein the first spacer is integrally formed with a lower surface of the first retaining clip, and the second spacer has a length corresponding to a diameter of the grid reinforcement material.
