Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 are basic views for explaining a reinforcing bar assembly for an implant shelf according to the present invention. The present invention basically adopts the structure shown in the basic drawing, but as shown in FIG. 5 described later, its planar shape is formed into a U shape.

The basic configuration of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in these basic drawings, a reinforcing bar assembly 1 for an implantable shelf according to the present invention is arranged between inner molds 2 and outer molds 3 having substantially similar shapes, and these molds 2 and 3. Mainly composed of rebar 5.

The inner formwork 2 extends substantially horizontally from the slope 6 and is folded back so as to reach the slope 6 again, so that a hollow chamber 7 for growing a plant is defined inside.

Specifically, as shown in detail in FIG. 5, the inner formwork 2 has a U-shaped planar shape, the protruding side surface 2a has a triangular shape, and the front surface portion 2b has a quadrangular shape. ing.

An angle Θ1 on the upper side of the slope of the triangular side surface 2a of the inner mold 2 is formed to be substantially equal to the inclination angle Θ2 of the slope. The inner formwork 2 is formed of, for example, a crimp wire mesh or expanded metal.

An outer mold 3 is provided on the outer side of the inner mold 2 with a predetermined distance D therebetween. Similar to the inner mold 2, the outer frame 3 has a U-shaped planar shape, the protruding side surface portion 3a has a triangular shape, and the front view 3b has a quadrangular shape.

An angle Θ3 on the upper side of the slope of the triangular side surface 3a of the outer mold 3 is formed to be substantially equal to the inclination angle Θ2 of the slope, similar to the inner mold 2. That is, the inner mold form 2 and the outer mold form 3 are formed so as to have substantially similar shapes.

Further, the outer mold 3 is formed of, for example, a crimp wire mesh or expanded metal, like the inner mold 2.

The inner mold form 2 and the outer mold form 3 are formed by the respective overhanging side surface portions 2a, 3
It is fixed at a position a by a stud bolt 8 so as to maintain a predetermined distance D.

Instead of the stud bolts 8, for example, reinforcing bars having substantially the same length as the predetermined distance D may be used and fixed by welding.

The above-mentioned predetermined interval D is a value substantially equal to the width obtained by subtracting the finishing margin from the desired wall thickness of the concrete wall of the implantation shelf described later.

A reinforcing bar 5 is arranged between the inner mold 2 and the outer mold 3. The reinforcing bar 5 is formed so as to have a shape substantially similar to the planar shapes of the inner mold 2 and the outer mold 3. That is, the reinforcing bar 5 has a U-shape, and is arranged between the inner mold frame 2 and the outer mold frame 3 along the U-shape.

Alternatively, the inner mold form 2, the outer mold form 3, and the reinforcing bar 5 may be preformed into a U shape and assembled on the slope 6 at the site. Then, any or all of the inner mold form 2, the outer mold form 3 and the reinforcing bars 5 are fixed to desired positions on the slope 6 by anchors 9. Prior to constructing the reinforcing bar assembly 1 for an implantation shelf on the slope, a concrete wall is usually formed on the slope.

Since the ground on the slope 6 has irregularities, the leveling material (6th
(See the drawing) is provided below the inner mold 2 and the outer mold 3.

As shown in FIG. 2 and FIG. 3, for example, anchors 9 are used to fix four positions of the reinforcing bar assembly for implantable shelves 1.

As described above, the overhanging side surface portions 2a and 3a of the inner mold 2 and the outer mold 3 that form the rebar assembly 1 for the implantation shelf have a triangular shape. The angles .THETA.1 and .THETA.3 on the upper side of the slope of the triangle are formed to be substantially equal to the inclination angle .THETA.2 of the slope, so that the upper edges of the inner mold frame 2 and the outer mold frame 3 are positioned substantially horizontally. Will be projected from the slope 6. That is, since the inner mold form 2 and the outer mold form 3 have substantially similar shapes, they are folded back in a U shape so as to project substantially horizontally from the slope 6 and reach the slope 6 again.

Further, between the inner mold 2 and the outer mold 3, the rebar 5
In addition, supplementary bar arrangement is performed if necessary.

Then, concrete or mortar is cast or sprayed between the inner mold 2 and the outer mold 3 on which the reinforcing bars 5 are arranged and on the surfaces of these molds 2, 3.

After applying this concrete or mortar, the outer form 3
Finish the outer surface with grout.

The concrete wall formed in this way serves as a planting shelf, and soil is loaded into the hollow chamber 7 inside thereof to grow plants.

Since the inner mold 2 and the outer mold 3 are made of wire mesh or expanded metal, they are embedded inside as a reinforcing material for a concrete wall.

As described above, it is possible to easily attach an implanting shelf to the slope protection structure by means of the reinforcing bar assembly 1 for the implant shelf, and improve the aesthetic appearance of the slope protection structure in greening. Since this reinforcing bar assembly 1 for implantable shelves can be easily installed without distinction between new installations, it is highly versatile.

Here, FIG. 5 shows a plan view of the reinforcing bar assembly 10 for an implant shelf according to the present invention. That is, in the present invention, the inner formwork 2, the outer formwork 3 and the reinforcing bar 5 are formed in a U-shape in a plan view, and the inner formwork 2 and the outer formwork 3 are formed substantially from the slope 6. It is bent in a U-shape so as to extend horizontally and reach the slope 6 again.

In this way, by forming the reinforcing bar assembly 10 for the implant shelf into a U-shape, the reinforcing bar assembly 10 for the implant shelf does not have a corner, and therefore is structurally strong without discontinuities.

FIG. 6 shows the lower parts of the inner mold 2 and the outer mold 3,
The state in which the leveling material 11 is installed in the concave portion of the slope 6 is shown. The leveling material 11 is made of a known material such as a hardened material, a soil material, or wire mesh.

Further, the reinforcing bar assembly 30 for an implanting shelf shown in FIG. 7 has strip-shaped iron plates 31 attached to the upper and lower edges of the inner mold 2 and the outer mold 3, respectively.

Thus, the upper and lower edges of the inner mold form 2 and the outer mold form 3,
By attaching the strip-shaped iron plates 31 along each other, even if these molds 2 and 3 are mechanically weak members such as a wire mesh, these formworks 2 and 3 are constrained to each other by the strip-shaped iron plate 31. As a result, it can be reinforced strongly.

The anchor 9 of the reinforcing bar assembly 30 for an implantation shelf is fixed to a strip-shaped iron plate 31 by welding or the like as shown in FIGS. 4 and 7. Particularly, on the upper side of the slope 6, if the anchor 9 is fixed to the upper and lower strip-shaped iron plates 31, it can be reinforced more strongly. Incidentally, FIG. 4 shows a strip-shaped iron plate 31 on the lower edge side of the inner mold 2 and the outer mold 3.
