Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to a natural stone revetment block for a steep slope applied to a steep slope.

[0002]

[Prior art]

 Conventionally, steep slopes are often constructed by the consolidation embankment method shown in Fig. 5 or the block embankment method shown in Fig. 6.

[0003]

[Problems to be solved by the invention]

 However, if the revetment method is applied, the slope will be covered with concrete blocks, etc., which will impair the natural landscape and disrupt the ecosystem with the back ground. These revetment methods had the problem that the construction was extremely complicated and required much labor and time.

[0004] The present invention is proposed in view of the above problems, and its object is to construct a steep slope inexpensively and efficiently as compared with a multi-stage car mat, etc. The aim is to provide a natural stone revetment block for steep slopes that can be constructed in a stable state on the slopes and that can exert an ecological conservation function that is excellent in natural scenery.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the natural stone revetment block for steep slopes of the present invention is arranged along a reinforcing bar lattice frame constituted by assembling reinforcing bars in a lattice shape. A plurality of natural stones are integrally connected with each other by anchors to stabilize the natural stones and prevent the natural stones from rotating.

In the natural stone revetment block for steep slope according to the first aspect, a plurality of natural stones are arranged below the reinforcing bar lattice-shaped frame, and the natural stone is attached to the natural stone mounting portion of the reinforcing bar lattice-shaped frame. One end of a pair of anchors is attached to two locations in the vertical and horizontal directions, and the other end of each anchor is inserted into a pair of connection holes formed in the natural stone. A coagulant is filled to integrally connect the rebar lattice-like frame and the natural stones (claim 2).

[0007]

[Embodiment of the invention]

 Next, the steep natural stone revetment block of the present invention will be described with reference to an embodiment shown in the drawings. A is a rebar lattice-shaped frame, and the rebar lattice-shaped frame A is configured by combining rebars 1 in a lattice shape.

As shown in FIG. 3, reference numeral 2 denotes an anchor. The anchor 2 includes a pair of U-shaped ends 2a, and both sides 2b extending linearly from each of the U-shaped ends 2a. And a U-shaped other end 2c formed at the other end of the both sides 2b. Reference numeral 3 denotes a plurality of natural stones for preserving natural scenery. Each natural stone 3 has a pair of connection holes 4 formed therein.

In the case of the present embodiment, there are six natural stones 3, which are arranged in two rows below the reinforcing grid frame A. One end 2a of a pair of anchor fittings 2 is attached to two places in the vertical and horizontal directions of the natural stone mounting portion of the rebar lattice frame A, and the other end 2c of each anchor fitting 2 is attached to each natural stone. Each of the connecting holes 4 is filled with a coagulant 5 so that the reinforcing bar lattice-shaped frame A and each natural stone 3 are integrally connected.

FIG. 4 is a vertical side view showing a state in which the natural stone revetment block of the present invention is installed as a retaining wall on a steep slope. As shown in Fig. 4, natural stone revetment blocks are installed in multiple stages along the steep slope, and the steep slope is covered with natural stones 3 for natural scenery conservation. At this time, since the reinforcing bar lattice-shaped frame A is configured by assembling the reinforcing bars 1 in a grid shape, the back stones 6 enter the gaps between the reinforcing bars 1 and the natural stones 3 and the back stones 6 are straightened. Will be engaged.

[0012]

[Effect of the invention]

 The steep natural stone revetment block according to the present invention is, as described in claim 1, a reinforcing bar lattice frame constituted by assembling reinforcing bars in a grid and a plurality of reinforcing bars arranged along the reinforcing bar lattice frame. The natural stone is integrated with the anchor so as to stabilize the natural stone and prevent the natural stone from rotating, etc. At this time, a plurality of natural stones are arranged below the reinforcing bar lattice-shaped frame as described in claim 2, and a pair of natural stones are provided at two locations in the vertical and horizontal directions at the natural stone mounting portion of the reinforcing bar lattice-shaped frame. Attach one end of the anchor fitting, insert the other end of each anchor fitting into a pair of connection holes drilled in each natural stone, fill each connection hole with a coagulant, Since the lattice-shaped frame and each natural stone are integrally joined, it is possible to construct multiple natural stones, for example, 6 natural stones, as one unit, which is easy to construct and is faster than multi-stage car mats. Inexpensive and efficient construction on the slope of the slope.

[0013] Further, since the reinforcing bars are assembled in a grid shape to form a reinforcing grid frame, the back rock is inserted into the gap between the reinforcing bars, so that the natural stone can be directly engaged with the back rock. It can be constructed in a stable state on a steep slope. In addition, since the gap between natural stones communicates with the back soil, it is possible to demonstrate an ecosystem conservation function that is excellent for natural scenery.
