Field of the Invention The present invention provides a space for fixing a slope and filling a vegetation base material in a greening work for promoting the growth of plants on the slope and for greening and protecting the slope. The present invention relates to a greening frame structure to be formed.

[0002]

2. Description of the Related Art Conventionally, in order to secure a natural environment, it has been widely practiced to fill an exposed portion of a rock surface of a mountain surface with soil and sow it to green the exposed portion.

As a method thereof, a plate-like wire mesh is adhered to a slope surface of a rock or the like in a state of being adhered thereto or floated by an anchor for several centimeters, and a vegetation base material such as soil is sprayed on the wire mesh, and the wire mesh method is used. Fix the vegetation base material on the surface of the surface,
It was widely practiced to grow plants there.

According to this method, the construction is easy and the cost is low, but the wire mesh coated in this way has a limit in the ability to fix the vegetation base material. In some cases, the vegetation base material was gradually washed away due to snowfall, etc., causing plant decline.

Therefore, as shown in FIG. 5, a net structure formed by a net body arranged along the slope 51 and a net body extending upward from the lower end of the net body has a V-shaped net structure. A method of growing a plant 55 by forming a vegetation space by fixing the body 52 on the slope 51 with an anchor 53 and filling the space with a vegetation base material 54 has been practiced.

[0006]

However, according to this method, it is difficult to secure a scaffolding at the time of working, especially when filling a vegetation base material or the like, or when sowing or planting seedlings, and in order to ensure work safety, Since a scaffold had to be set up separately, it was extremely troublesome including removing the scaffold after the work. In addition, it is difficult for the greening shelf 52 with such a mesh to closely contact the slope with various unevennesses or slopes with varying slopes. Had a problem that the work was troublesome and difficult because it had to be bent on site.

Therefore, the present invention proposes a frame structure for slope revegetation, which solves the above problems, can be installed by simple and safe work, and can form a stable vegetation base on the slope. It is what

[0008]

According to the present invention, there is provided a slanting frame arranged along a slope, a vertical frame connected to the lower end of the slanting frame upward, a slanting frame and a vertical frame. The above-mentioned problem is solved by a horizontal frame that is erected between both upper end parts of It was taken as a means to

[0009] It is preferable that at least one of these three frames is of a prefabricated type which is made as a separate body and is connected by a connecting tool, which is connected on site or previously connected. , Fix it on the slope with anchor etc. Since the scaffolding portion is provided at the tip of the horizontal frame, the work of filling the vegetation base material and the like can be performed extremely safely thereafter.

Further, by roughening the crosspiece of the slant frame,
It becomes easier for the slanted frame to contact the uneven slope, and by providing vertical bars and horizontal bars at fine intervals in the vertical frame,
It becomes possible to hold the vegetation base material and prevent it from falling.

Further, by providing the slant frame with the engaging portion for the net body stretched on the slope, the frame structure can be easily fixed on the slope without hammering the anchor or the like. And work becomes easier.

Furthermore, by allowing the scaffolding portion of the horizontal frame to be bent with the tread surface facing inward, if the scaffolding portion is bent after the work, fallen leaves and the like are deposited on the surface of the filled vegetation base material or the like. Let's make it possible to feed it.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the frame structure 2 according to the present invention. The oblique frame 21 is arranged along the slope and the vertical frame 22 is connected to the lower end of the oblique frame 21 upward. And a horizontal frame 23 that is installed between both upper ends of the slant frame 21 and the vertical frame 22.
Is formed of a hard wire material such as a steel wire which is surface-treated by galvanizing or resin processing and has excellent corrosion resistance. The wire diameter is about 3 mm to 10 mm. Then, in each of the frame bodies of the frame structure 2, when the inclined frame 21 is arranged along the slope according to the slope of the slope where the greening work is performed, and the vertical frame is directed vertically upward, The horizontal frame 23 is preferably dimensioned so as to be installed substantially horizontally on the upper part of the vertical frame 22.

The sloping frame 21 preferably has as few crosspieces as possible except for the four sides of the frame so that it can be applied to any unevenness on the slope, but it is necessary to maintain the shape of the frame and obtain a predetermined rigidity. Only the number of crosspieces 41 are provided at appropriate intervals.
Since the frame structure 2 is usually formed in a shape larger in the width direction than in the vertical direction in order to green the slope without gaps, in this case, the diagonal frame 21 is provided with only a few vertical bars. It will be.

Further, the vertical frame 22 is provided with vertical and horizontal bars 42 at relatively small intervals in order to securely hold the vegetation base material and the like to be filled later.

The horizontal frame 23 includes a slanted frame 21 and a vertical frame 22.
The V-shaped cross-section formed by and serves as an opening stopper for keeping the predetermined opening width without being deformed by a load or the like, and the tip end portion is projected toward the end of the vertical frame 21. The scaffolding portion 24 is provided so that The scaffold portion 24 can be bent face up after the work. On the base end side of the horizontal frame 23, crosspieces 43 are provided at intervals such that branches and stems can pass without hindering the growth of plants, and the scaffolding 24 at the tip is for safe work.
It is preferable that the crosspieces 45 are provided at slightly smaller intervals so that the crosspieces 45 do not fall even when the feet are put on the crosspieces.

These three frames are connected by a connecting tool 25 on site or in advance at the time of manufacturing. When connected in advance, at least one of the vertical frame 22 and the horizontal frame 23 is made rotatable by a hinge or the like so that a plurality of frame structures 2 can be stacked during transportation or storage. Good to do.

FIG. 2 shows an example of the slope greening work using the frame structure 2 of FIG. 1, and the steps of the greening work will be described below with reference to FIG.

First, the slant frame 21 of the frame structure 2 assembled in advance is placed in contact with the slope 1, and the slant frame 21 is fixed to the slope 1 by the anchor 3 cast on the slope 1. The anchor 3 is made of a material and in a form suitable for the type of slope 1 to be constructed, and has a locking portion 3 such as a hook or a male screw at the base end.
1 is formed.

Then, inside the frame structure 2, a bag body 4 for holding the vegetation base material 6 so as not to drop or run off is installed. The bag body 4 is flexible so that it can wrap the vegetation base material 6 inside the net structure body 2 and at the same time can take root in the natural ground 10 without hindering the elongation of the root of the plant 7. It is made of, for example, a fine net or a non-woven fabric having a large number of holes. Then, the bag body 4 is fixed to the frame structure 2 with, for example, a thin wire or a string, or is attached to the frame structure 2 by being hooked on the end side thereof.

Further, by installing the heat insulating material 5 inside the bag body 4, the plant 7 can be protected from freezing and the like. As the heat insulating material 5, a material having flexibility and not inhibiting growth of plant roots is used.

If the bag body 4 and the heat insulating material 5 are attached to the frame structure 2 in advance and then the frame structure 2 is fixed to the slope 1, the on-site process is simplified, but the frame structure is reduced. The body 2 may be fixed to the slope 1 and then attached.

Next, the horizontal frame 23 is laid over the upper portion of the vertical frame 22, and the position is appropriately fixed by, for example, a wire or a string.

In this way, after the frame structures 2 are attached at appropriate intervals over the entire slope 1, the vegetation mainly composed of park compost and site-generated soil is provided by hydraulic excavators or the like in the respective frame structures 2. The base material 6 is introduced and seeds are sown there. Alternatively, a vegetation base material containing seeds may be added.

Finally, as shown in FIG. 3, the scaffolding portion 24 is bent upward so that the fallen leaves 8 and the like do not fall and the vegetation base material 6
Allow it to stay on and deposit.

On the slope 1 thus constructed, the stems and trunks grow and fallen leaves accumulate,
The frame structure 2 gradually disappears from the outside, and greening progresses. On the other hand, as the root penetrates the heat insulating material 5 and the bag body 4 and enters the natural ground 10, the natural ground 1
0 and the plant 7 are united. Therefore, it gradually approaches the natural state and the greening is completed.

In the above description, the preassembled frame structure 2 is fixed on the slope 1, but the frame structure 2 may be assembled with the connector 25 while being installed on site.

FIG. 4 shows a different embodiment of the present invention.

The frame structure 2a is composed of the vertical bars 41a of the oblique frame 21a.
Locking portions 46 and 47 are provided at both ends of the locking portion 46, 47, respectively, and the locking portions 46 and 47 are locked to the mesh surface stretched on the slope by fixing them on the slope.

The other construction and construction method are exactly the same as in the case of the frame structure 2 of FIG.

The frame structure 2a can be fixed without using a tool or the like, and even if the frame structure 2a is extremely uneven and it is difficult to directly ground the frame structure 2a on the slope, the frame structure 2a is stretched on the slope. Since the frame structure 2a is attached in contact with the net body, stable fixing is possible.

[0033]

EXAMPLE Next, an example of a slope of a hexagonal gradient will be described.

As the wire material forming the frame, a steel wire having a diameter of 6 mm, which was surface-treated by zinc plating, was used. And for the diagonal frame, 1 in the frame body of 35 cm x 90 cm
A vertical frame is provided at 5 cm intervals,
A vertical frame at 15 cm intervals and horizontal bars at 5 cm intervals in a frame measuring 90 cm x 90 cm is used as a horizontal frame for 18c.
A vertical crosspiece was provided all over the frame body of m × 90 cm at intervals of 15 cm, and only two horizontal crosspieces were provided at intervals of 5 cm from the tip. In addition, a steel wire having a diameter of 5 mm and a diameter of 3.2 mm was attached to the vertical rail by welding. Then, C rings were attached to the upper and lower sides of the oblique frame at intervals of approximately 15 cm, and the horizontal frame and the vertical frame were connected to form a slope greening frame structure.

Next, with the slanted frame along the slope, φ16 m
After fixing the slanted frame to the slope with an anchor of m, 40 cm in length, and then rotating the horizontal frame around the hinge axis and installing it on the upper edge of the vertical frame, the vertical frame upper end and the horizontal frame are appropriately arranged. It was fixed by connecting several points with a wire. In addition, inside the frame structure, a net for earth retaining and a heat insulating sheet made of a polyethylene foam sheet, a polypropylene foam sheet, or the like were previously attached.

Then, the soil was put into the frame structure, and the seeds of Yamahagi and Weaselfish were sown therein.

As a result, after 6 months, yamahagi and weasel haggies had grown from 5 cm to 20 cm. And in the autumn, about a year later, we could see some 60 cm. Furthermore, in the autumn of the following year, Yamaha's 150 to 200 cm
It had grown into a tree, flowers were blooming, the slope was covered with wood, and greening had progressed.

EFFECTS OF THE INVENTION When the frame structure for slope slope greening of the present invention is used, the scaffolding portion is provided at the tip of the lateral frame, so that the scaffolding is secured without performing additional work for installing the scaffolding, which is small. Work can be performed easily and safely in the process.

Further, the load can be easily attached and fixed by using an anchor or the like cast on the slope, and moreover, a stable vegetation space is formed by fixing the opening with a horizontal frame, so that the load can be increased. It does not deform even when applied, and the vegetation base stabilizes.

Further, the material cost is extremely low because it is constructed by using a general metal rod or the like without using a special shape or a special material.

By forming at least one of the slanted frame, the vertical frame and the horizontal frame as a separate body, the size of the opening of the frame body can be set according to each purpose, and the integrated type Compared to the frame, problems such as economical waste and difficulty of mounting do not occur.

In addition, if three kinds of frame bodies are prepared, for example, only the slanted frame having several kinds of lengths, even if the slope of the slope changes, a vegetation space having an appropriate size can be prepared accordingly. It can be formed and is versatile.

Further, if the assembly type is connected by a connecting tool, a plurality of frame structures can be piled up in a separated state or a folded state during transportation or storage, which saves space, resulting in cost reduction. Is cheaper.

When the slanting frame is provided with a hook or the like, the frame structure can be easily fixed by tensioning the mesh on the slope without using an anchor or the like. In addition to being simple, it is possible to stably attach to any slope having unevenness.

Furthermore, if the scaffolding portion of the lateral frame can be bent so that the tread surface is on the inside after the work,
Since fallen leaves and nuts can be deposited on the vegetation base, nutrients can be naturally obtained, and plant decline can be prevented even on a steep slope.
