BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reticulated stone-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a back-stone-fixed stone structure and a construction method thereof, and more particularly, to a back-stone-type stone structure and a construction method thereof, .

There is a risk of erosion, rockfall, and collapse when the cut surfaces, slopes, and rocks generated during civil works are left untreated. Therefore, it is necessary to construct a retaining wall structure to prevent erosion or collapse at these places and to match with the surrounding landscape.

In addition, the retaining wall is a concrete structure installed to prevent collapse of a slope, a slope, a rock, and the like formed on a residential site, a roadside, and the like. Normally, these retaining walls are formed by building blocks made of concrete or by pouring concrete.

Conventional retaining wall structures have been widely used for brick or concrete structures due to the convenience of construction and economical efficiency. However, retaining walls made of concrete or brick are not environmentally friendly and can harm the surrounding landscape because of their uniform color and shape.

In addition, the retaining wall, which is a concrete structure, has a low flexibility, and there is a high risk of settlement or conduction due to poor drainage, a long construction period, a serious problem of destroying ecology and environmental degradation, there was.

In recent years, in order to solve this problem, it is a tendency to create a more environmentally friendly environment by constructing a stone structure by using a blast stone or natural stone instead of a concrete retaining wall structure. However, due to the difficulty of harvesting and transporting the retaining wall structures using blasting stones or natural stones, it was possible to increase the construction cost, and it was difficult to obtain natural stone or blasting stone of the desired size. In addition, when the length of the blasting stone is increased, there is a risk of being damaged by the pressure of the gravel applied to the back surface of the blasting stone.

Instead of the wire 211, a wire, a reinforcing bar, or the like may be used.

In addition, an anchor embedding holes (not shown) may be formed at a position where a predetermined number of the second decorative stones 220 and a predetermined number of the first decorative stones 210 overlap each other, Bolts 212 are used to fix the overlapping portions.

Further, the expandable anchor bolt 212 used in the present invention is installed as follows.

8A to 8D, an anchor embedding hole 16 is formed in an individual decorative stone 200 by using a known drilling machine 15.

Next, using the expandable anchor bolts 212, the thread 14-2 is fixed to the decorative seats 10, 11 in a state where the body 14-1 is fixed to the anchor embedding holes 16 of the decorative seats 10, 11). The expandable anchor bolt 212 applied to the present invention has a body 14-1, a threaded portion 14-2, and an enlarged wedge 14-3, And a stopper 14-4 is formed at an intermediate portion of the body 14-1. The extended wedge 14-3 is extended by the tapered portion 14-5.

Next, it is fixed to each threaded portion 14-2 of the plurality of anchor bolts 14 fixed to the anchor embedding hole 16 by using the nut 14-7. More specifically, as shown in FIG. 4D, when the nut 14-2 is tightened after the washer 14-6 is inserted into the threaded portion 14-2, the body 14-1 of the anchor bolt 14, The expanding wedge 14-3 is expanded and tightly fitted into the ornamental stones 210 and 220 so that the body 14-1 of the expandable anchor bolt 212 is further raised . And the individual ornamental stones 200 more stably connected by the expanding anchor bolts 212 can be fixed.

In addition, the space between the individual ornamental stones 200 may be filled with fillets of small size, or a nonwoven fabric may be installed to prevent the foreign matter from flowing out.

Next, FIG. 9 is a view showing a vertical fixture in a rear-bottom fixed-type stone structure according to the present invention.

Referring to FIG. 9, the vertical fixture 120 of the rear-view fixed-type stone structure according to the present invention is embedded in the hexahedron-shaped second concrete 110 with the lower portion of the rod 111 having a desired length. The material of the column 111 is preferably steel or stainless, but is not limited thereto, and any material may be used as long as it is a low-cost and strong material.

In addition, the second concrete 110 is constructed such that a lower portion of a predetermined height is embedded in the foundation concrete 100. Thus, the vertical fixture 120 is firmly fixed to the foundation concrete 100 as a foundation.
