Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope coating structure having natural stone layered on its surface.

[0002]

2. Description of the Related Art In the construction of a conventional concrete block wall structure, a concrete block to be laid is provided with a retaining portion, and concrete is poured between the blocks to be integrated.

[0003]

In the conventional masonry structure of the concrete block wall, since the surface is constituted by the concrete portion, the surrounding masonry joint of the block is combined with the presence of the artificial joint joint of the block. The harmony with the natural environment was spoiled, and the integration of each block was difficult.

[0004] The present invention has been proposed in view of the above-mentioned problems of the prior art, and aims at harmonizing with the surrounding natural environment, having excellent workability, and having a structurally high reliability. It is an object of the present invention to provide a natural stone surface and a backside concrete casting slope covering structure.

[0005]

In order to achieve the above-mentioned object, a natural surface stone and a rear concrete casting structure according to the present invention are provided with a reinforcing bar or a steel mesh between frame pieces of a steel frame. And a plurality of natural stones are arranged in a row on the net-like piece and adhered with an adhesive, and on the back surface of the frame, a horizontal part of an L-shaped part composed of a vertical part and a horizontal part is provided. A fixture is provided by extending an inclined part extending obliquely upward from the tip of the part toward the frame body, and the vertical part of the fixture is attached to the frame piece via a bolt and nut. While tightening, the tip of the inclined portion piece is fastened to the mounting plate planted from the frame piece via a bolt nut, and concrete is poured between the back surface of the frame body and the backing material. It is configured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below with reference to the drawings. 4 to 6 show a pedestal A, in which a mesh portion 2 is braided and stretched by a reinforcing bar or a steel frame between frame pieces of a steel frame 1 and natural stones 3 are laid on the mesh portion 2 vertically and horizontally. It is bonded via an adhesive such as an epoxy resin. In addition, a fixing bracket 4 fixing insert (not shown) described later is buried in required portions of the rectangular frame body, and thus a natural stone unit B is configured.
(Refer to FIG. 2 and FIG. 3) The fixing bracket 4 is composed of a vertical piece 4a and a horizontal piece 4b.
It is composed of a mold piece and an inclined piece 4c extending obliquely upward from the tip of the horizontal piece 4b.

The vertical portion 4 of the L-shaped piece of the fixing bracket 4 is previously provided on the back surface of the natural stone unit B at the bottom.
a is fixed via bolts 5 using an insert embedded in the frame piece of the unit B, and the upper end of the inclined portion piece 4c is screwed to the insert embedded in the frame piece of the unit B. It is fastened to the mounted mounting plate 6 via a bolt and nut 7, and the lowermost natural stone unit is mounted on the foundation concrete C together with the fixing metal 4, and is placed between the backfill crushed stone 8 and the first natural stone unit. Cast-in-place concrete 9 is cast. In the figure, reference numeral 10 denotes a drain hole.

Next, at the time of joining the second-stage cast-in-place concrete 9, a joining bracket consisting of the vertical and horizontal pieces 4 a _and 4 b and the inclined piece 4 c is attached to the back of the natural stone unit B of the second step. The second stage cast-in-place concrete 9 is placed between the natural stone unit B and the backfill crushed stone 8 while being mounted on the lowest natural stone unit B. a ₁ is a cast-in-place concrete joints of the bottom.

In the same manner, a natural stone unit B is erected along the slope, and cast-in-place concrete is poured between the natural stone unit B and the backfill crushed stone 8. Figure 10 is the drain hole, 11 crest concrete, a _1, a _2, a _3, a ₄ are respectively the second concreting, and the third concreting, and the fourth concrete It is a cast-in-place concrete transfer section at the time of construction.

[0010]

As described above, according to the present invention, a net-like piece made of a reinforcing bar or a steel frame is stretched between rectangular steel frames, a plurality of natural stones are arranged on the net-like piece, and bonded with an adhesive. To form a natural stone unit, and use the unit as a formwork,
Concrete is poured between the back of the unit and the backing material, and L
The vertical piece and the inclined piece of the fixing bracket extending obliquely upward from the tip of the horizontal piece in the mold piece toward the frame from the tip of the horizontal piece are fastened to the back surface of the frame via bolts, nuts and inserts. Since the concrete was cast between the back of the frame and the backfill material, the natural stone unit was integrally connected to the slope, and there was no vegetation part compared to the conventional vegetation concrete, and the joints between the blocks were made. Disappear and a natural landscape structure is constructed.

[0011] In addition, the construction can be dealt with freely in response to any slope slope, can be effectively constructed according to the site, and furthermore, by casting the cast-in-place concrete, the construction cost can be greatly reduced as compared with the vegetation concrete block. We can save.
