2. Description of the Related Art Conventionally, concrete retaining walls have been employed on dikes or river embankments or slopes beside roads, which are constructed for damping water currents and earth and sand across rivers and valleys. This type of concrete retaining wall is installed in various places including mountainous areas for the purpose of preventing landslides and the like. It also plays a role in ensuring the daily safety of the surrounding area and minimizing damage in the event of a natural disaster.

[0003] In addition, concrete is mainly used widely for dams and concrete retaining walls constructed for such purposes. For example, when constructing a dam, first, a concrete foundation is constructed on the ground where a river or valley is to be constructed, and then a formwork that matches the outer shape of the dam to be constructed is assembled. Concrete is poured into the frame, and after a predetermined time elapses, the form is removed to build a dam. In addition, slopes beside the roads and concrete retaining walls of river embankments are constructed in substantially the same manner.

[0004]

The above-described dams and concrete retaining walls have usually been constructed in a natural environment as the purpose indicates. However, since it is constructed of concrete, and the surface is exposed, the appearance is not suitable for the surrounding natural environment, resulting in an unnatural scenery, which impairs the natural scenery.

[0005] In particular, in the case of concrete retaining walls of river embankments, while the safety of the surrounding area is provided, animals and plants are extremely difficult to live by turning over from the embankment walls conventionally formed of earth and sand, stones and the like. It was a concrete retaining wall. As a result, the living environment of many animals and plants living on the natural embankment has been destroyed, resulting in the destruction of the natural environment. The same was true for dams and concrete retaining walls beside roads.

Further, when constructing a dam or concrete retaining wall, a relatively large-scale construction is performed for the construction of the dam or concrete retaining wall, and the completed product is large. Since assembling and removing the concrete panel is indispensable, the work has been troublesome.
In addition, since relatively high precision is required when assembling the concrete panel in order to finish the surface flat, further work is required. In addition, concrete panels and the like used for the formwork have been discarded after being removed, resulting in waste of resources.

Accordingly, the present invention provides a natural embankment and the like, while maintaining the function and effect of conventional dams and concrete retaining walls at all, even when constructed in a natural environment. It can protect the living environment of many animals and plants used as places, and can be completed with extremely simple work in construction, and can use resources effectively. It is an object to provide a construction method.

It is fixed by tightening. Thus, the wood bar 2a is fixed to each of the three connecting rods 3 by the fixing member 4 including the bolt 4a, the washer 4b, the nut 4c, the long nut 12a, the screw bar 4d, and the like.

Further, a recess 6 having a depth of about 5 cm is provided in a portion of each wood rod 2a where the fixing member 4 is provided, so that the fixing member 4 such as the tip of the bolt 4a does not protrude from the surface. It has become. The fixing member 4 for fixing the wood rods 2a and the connecting rods 3 located above and below is composed of the thickness of the washer 4b and the nut 4c and the length of the bolt 4a protruding about 1 to 2 cm from the fixing member. The amount of protrusion is 4. That is, it only protrudes from the back surface of the decorative mold frame front member 2a by about 2 Cm to 6 Cm. A fixing member 4 for fixing the wood rod 2a and the connecting rod 3 located at the center has a screw rod 4d of a predetermined length inserted therein, and tightens a nut 4c from the back via a washer 4b.
It is fixed by tightening a long nut 12a from the front via a washer 4b, and a screw rod 4d projects from the back of the connecting rod 3. As will be described later, a mortar of the same color as the wood or a filler material 5 such as cork or wood chips mixed with an adhesive is embedded in a concave portion 6 provided on the surface of each wood rod 2a. Is processed to be invisible.

Each of the wooden rods 2a constituting the decorative mold frame member 2 does not need to have a curved surface, and may be simply a square bar. The connecting rod 3 that supports the decorative form surface member 2 from the back surface does not necessarily need to protrude from above and below the decorative form surface member 2 and may protrude from one side or separate sides. The number of the connecting rods 3 does not need to be two, and may be three or more as long as the connecting rods 3 can be assembled vertically and horizontally.
The material of the wood rod 2a is not limited to cedar or larch,
Any wood may be used, and any size may be used as long as it can be assembled vertically and horizontally. Further, it is not always necessary to perform antiseptic and insect treatment on the wood, but it is preferable to perform the antiseptic and insect treatment in order to maintain the state at the time of construction for a long time.

Then, in accordance with the area and shape of the retaining wall to be constructed, the decorative form material 1 is further assembled up, down, left, and right as described above. Next, the appearance of the thus-assembled retaining wall decorative formwork 10 will be described. FIG. 4 is a main part front view showing an assembled state of a retaining wall decorative formwork according to one embodiment of the present invention,
FIG. 5 is a main part rear view showing an assembled state of the decorative mold for retaining wall according to one embodiment of the present invention.

As shown in FIG. 4, when the decorative formwork 10 for a retaining wall of the present embodiment is viewed from the front side, for example, when the decorative formwork material 1 indicated by a solid line is mainly described, it is indicated by a solid line. On the left and right of the decorative form material 1, decorative form materials 1 of the same shape are arranged, and the decorative form materials 1 are vertically arranged so that the contact portions of the arranged decorative form materials 1 are on the vertical center line. 1 is touching. The connecting rod 3 fixed to the back surface of the decorative form surface member 2 is hidden behind the decorative form surface member 2 and only the decorative form surface member 2 is arranged from the surface. become.

On the other hand, as shown in FIG. 5, when the decorative form 10 for retaining wall of this embodiment is viewed from the back, it is fixed to the back of the decorative form 1 that is assembled vertically and horizontally. The protruding portions of the connecting rods 3 cover the rear surfaces of the upper and lower decorative formwork front members 2 with each other. Accordingly, the upper two decorative form members 1 placed on the upper surface of the back surface of the decorative form surface member 2 shown by the solid line
Projecting portions of the left and right connecting rods 3 are covered, and similarly, the projecting portions of the left and right connecting rods 3 of the two lower decorative frame members 1 are covered at the lower portion. Conversely, the protruding portions of the connecting rods 3 of the decorative formwork 1 indicated by solid lines cover the back surfaces of the decorative formwork front members 2 of the upper and lower decorative formwork 1. further,
In such a state, it is assembled continuously vertically and horizontally.

As shown in FIG. 5, by straddling the upper and lower back surfaces of the assembled decorative form material 1 and striking the support plate 8, the upper and lower decorative form materials 1 are fixed. The decorative mold members 1 can be more firmly fixed to each other. In this way, if the upper and lower decorative form members 1 are fixed by the support plate 8, it is possible to prevent the decorative form member 1 from rising when concrete is poured.

Therefore, in the decorative mold 10 for a retaining wall configured as described above, the decorative form surface member 2 of the decorative form material 1
Since any material and size of wood can be used as the material, the wood rod 2a is used as scrap material generated in various works.
Can also be used, resulting in effective use of resources. Further, since the decorative mold frame material 1 itself has a simple structure, it can be manufactured very easily and is suitable for mass production, so that it can be provided at a relatively low cost.

Next, a construction method in the case of actually constructing a dam using the decorative form 10 for retaining walls of the present embodiment will be described. FIG. 6 is a side view showing a case where a dam is constructed by using a decorative form for retaining wall according to one embodiment of the present invention, and FIG. 7 uses a decorative form for retaining wall according to one embodiment of the present invention. FIG. 8 is a front view showing the appearance of the embankment, FIG. 8 is a rear perspective view showing the decorative formwork material located at the lowermost end of the decorative formwork for retaining wall in FIG. 7, and FIG. It is a principal part expanded sectional view which shows the assembly state of a decorative mold.

In the case of constructing a bank using the decorative form 10 for retaining walls of the present embodiment, the bank is constructed sequentially through predetermined steps. For example, as shown in FIG. 6, the work is divided into three stages in the range of A to C. In this case, first, the foundation 11 for a dam is constructed with concrete. At this time, the support pile 13a such as a reinforcing bar is buried in the foundation 11 so as to protrude from the upper surface,
On the surface of the base 11 slightly inclined as shown in part A, a screw rod 4d protruding long on the back side while the back surface of the decorative frame material 1 dedicated to the base part is in contact with the surface of the base 11
Is embedded in the foundation 11 as an anchor member. Then, from the surface of the decorative form material 1, the decorative form material 1 is supported by a surface support member 12 composed of each tube or the like.

When the foundation 11 is completed, as shown in the section B, the decorative mold 1
The ordinary decorative form members 1 described with reference to FIG. 1 to FIG. Here, as shown in part B, the decorative form materials 1 are assembled in a 5-tiered manner. In other words, since one decorative form member 1 constitutes the decorative form surface member 2 by three wood rods 2a, the cross section is 15 wood rods 2a.
In a stacked state. At the same time, each decorative form material 1
Each decorative form material 1 is supported from the surface by a surface support member 12 such as a tube. Further, a screw rod 4d protruding from the back side of the decorative form material 1 and the support pile 13a are fixed by a back support member 13 made of a reinforcing bar, and each decorative form material 1 is supported from the back. The screw rod 4d and the support pile 13
a and the back support member 13 are fixed by welding or the like. In particular, if the screw rod 4d and the vicinity of the root of the support pile 13a are connected by the back support member 13, the strength is increased, and each decorative frame 1 can be supported in a relatively stable state. When the assembling and supporting of the decorative form 10 for the retaining wall is completed in this way, concrete is driven to the position indicated by the two-dot chain line of the portion B, and the supporting pile 13a is buried in the upper surface of the concrete as in the case of the foundation 11.

Further, when the concrete in the portion B is hardened, as shown in the portion C, the decorative form materials 1 are further stacked one after another. Each of the decorative form materials 1 assembled in four stages is supported by the surface support member 12 from the surface, and the decorative form material 1 is
And a screw rod 4d protruding long from the back side of the decorative form member 1 and the support pile 13a are fixed by the back support member 13 such as a reinforcing bar. When the assembling and supporting of the retaining wall decorative form 10 are completed, concrete is poured to the position indicated by the two-dot chain line in the portion C, and after the concrete solidifies, the surface support member 12 is removed and the upper part of the dam is removed. In order to trim the retaining wall decorative form 10 and conceal the fixing member 4 on the surface of each wood bar 2a, the concave portion 6 of each wood bar 2a has a mortar of the same color as that of the wood or a cork or wood chip or the like mixed with an adhesive. The filling material 5 is embedded, and the dam is completed.

Therefore, as shown in FIG. 7, the appearance of such a dam becomes as if it were constructed by stacking the wooden rods 2a on the whole, so that it becomes very familiar with the surrounding natural environment in appearance, and Does not spoil the scenery. In addition,
As the decorative formwork member 1 located on the inclined portion at the center of the bank, a decorative formwork front member 2 cut in accordance with the inclination is used.

Further, as shown in FIG. 8, the decorative form material 1 dedicated to the base portion described above is a decorative form surface member 2a.
As a connecting member fixed to the back surface of the base member, a metal connecting plate 7 having a width of about 5 cm and a length of about 40 cm is used. The metal connecting plate 7 projects above the decorative form surface member 2, and the back surface of the decorative form surface member 2 a is cut into a concave shape by the thickness of the connecting plate material 7. The connecting plate 7 is fitted. Therefore, the back surface of the decorative form material 1 dedicated to the base portion is covered with the decorative form surface member 2.
The connection plate 7 made of metal as a connection member is in a substantially flat and flush state.

As shown in FIG. 9, the surface support member 12 for supporting the decorative form material 1 from the surface includes a long nut 12a of about 4 cm in length and a relatively short screw rod of about 3 cm to 6 cm in length. 12b, a substantially V-shaped metal fixing member 12d,
Utilizing a wedge member 12e to be inserted into the hole of the fixing member 12d, a support rod 12c made of a steel pipe such as a square tube is used.
Are assembled vertically and horizontally in a grid pattern. In other words, when the decorative form material 1 is supported by the surface support member 12, the screw rod 4b protruding inside the concave portion 6 of the middle wood bar 2a constituting the decorative form surface member 2 of the decorative form material 1 Is a long nut 12
a is screwed, and a screw rod 12b is screwed to the other of the long nut 12a. Further, a V-shaped fixing member 12d is screwed and fixed to the tip of the screw rod 12b. The V-shaped fixing member 12d is a support rod assembled in a grid by a wedge member 12e. It is fixed in a contact state to the surface of 12c.

When the poured concrete is solidified and the surface supporting member 12 is to be removed, the wedge member 12e is removed from the V-shaped fixing member 12d, so that the lateral supporting rod 12 is removed.
c and the vertical support bar 12c can be easily removed. Next, the V-shaped fixing member 12d, the screw rod 12b, and the long nut 12a are removed from the screw rod 4d, and the nut 4c is screwed to the screw rod 4d. The long nut 12a is used again for assembling the decorative form material 1, and the surface support member 12 is also reused when constructing the decorative form 10 for retaining wall.

When a dam is constructed using the retaining wall decorative formwork 10, it may be constructed in any number of stages, and the decorative formwork material 1 to be assembled at each stage may be stacked in any number of stages. Further, the surface support member 12 and the back support member 13 may be of any material and structure as long as the support frame 10 can be supported from the front surface or the back surface. further,
In the present embodiment, the case where the direction of the decorative form material 1 is assembled with the longitudinal direction of the decorative form surface member 2 being set to be horizontal has been described. It is also possible to assemble in a horizontal direction with the direction being vertical, or in some cases with an oblique direction in the longitudinal direction.

Accordingly, the retaining wall decorative form 10 constructed by the above-described method looks as if it is constructed by stacking the timber rods 2a over the entirety, and at the same time, has no effect of the conventional dam. Since it is not necessary to remove the retaining wall decorative form 10 after completion without damaging the work, labor for the work can be saved, and the work can be completed in a relatively short time. Further, the necessity of removing the retaining wall decorative form 10 eliminates the necessity of assembling the concrete panel with relatively high accuracy in order to finish the surface flat as in the case of the conventional form using the concrete panel. Because the surface of the retaining wall decorative form 10 is made of the wooden bar 2a, the appearance is not impaired even if there are some irregularities. Therefore, high precision is not required. It can be omitted, and construction preparation and construction can be completed in a short time.

Next, a construction method in the case of constructing a concrete retaining wall beside a road using the decorative form 10 for retaining wall of the present embodiment will be described. FIG. 10 is a side view showing a case where a slope is constructed by using a decorative form for retaining wall according to one embodiment of the present invention, and FIG. 11 is a view of a slope using the decorative form for retaining wall of FIG. It is a front view showing the appearance.

In the case of constructing a concrete retaining wall beside a road by using the decorative form 10 for retaining wall of the present embodiment, the concrete retaining wall is constructed sequentially through predetermined steps in the same manner as in the case of constructing the dam. For example, as shown in FIG. 10, a case where construction is performed in three stages D to F will be described. First, the wall surface on the side of the road is slightly cut off, and the foundation 11 is built. At this time,
The support pile 13a made of a reinforcing steel is driven into the foundation 11, and the support pile 13a is driven into the ground to support the lower end portion of the decorative form 10 for retaining wall.

Next, as shown in part E, the decorative form material 1
Are sequentially stacked, and the surface of the decorative form material 1 is
The decorative form material 1 is supported from the front. At the same time, the screw rod 4d protruding from the back side of the decorative form material 1 and the support pile 13a are fixed by welding with the back support member 13 made of a reinforcing bar, and the decorative form material 1 is supported from the back. Also in this case, if the screw rod 4d and the vicinity of the root of the support pile 13a are connected by the back support member 13, the decorative form material 1 can be supported in a state in which the strength is stable. When the assembling and support of the retaining wall decorative form 10 are completed, concrete is driven into a position indicated by a two-dot chain line at the portion E, and the support pile 13 is formed.
a is arranged.

Further, when the concrete in the portion E is hardened, the decorative form material 1 is further stacked as shown in the portion F,
It is supported by the surface support member 12 from the surface of the decorative form material 1 and supported by the back support member 13 from the back. When the assembling and supporting of the retaining wall decorative form 10 are completed, concrete is poured to a position indicated by a two-dot chain line in the portion F.
The fence 14 and the fence support pile 14a are buried on the upper surface, and after the concrete has solidified, the surface support member 12 is removed, and the same color as the tree is provided in the concave portion 6 formed on the surface of the wood rod 2a of each decorative formwork 1. A sealing material 5 such as cork or wood chips mixed with mortar or an adhesive is embedded, and the fixing member 4 is hidden. Thereafter, the fence 14 and the fence support pile 14a are welded and fixed by the back support member 13 made of a reinforcing bar,
The slope construction is completed.

Therefore, the appearance of the retaining wall constructed in this way looks as if the wooden rods 2a are entirely stacked as shown in FIG. Further, a fence 14 is provided on the upper surface of the retaining wall, and the fence 14 is provided for preventing falling.
It may not be necessary to provide it.

In the above description, the back support member 1
Although the case where the support pile 13a for 3 is arranged on concrete has been described, the support pile 13a is buried in the rear cliff surface,
The back support member 13 may be fixed using the support pile 13a.

Further, a construction method in the case of constructing a concrete retaining wall of a river embankment using the decorative form 10 for retaining wall of the present embodiment will be described. FIG. 12 is a side view showing a case where a river embankment is constructed using the decorative form for retaining wall according to one embodiment of the present invention.

The construction of the concrete retaining wall of the river embankment using the decorative form 10 for retaining wall of the present embodiment is also performed through the predetermined steps, similarly to the case of constructing the concrete retaining wall beside the road. To construct. For example, FIG.
It is a figure which shows the concrete retaining wall of the river embankment constructed in steps, and the construction method of G part-I part is substantially the same as the said concrete retaining wall of the said roadside.

Therefore, the retaining wall constructed as described above can be used on a conventional embankment wall made of earth and sand, stone and the like, which is a living space for animals and plants, without impairing the effect of the conventional retaining wall at all. Can provide a close living environment. For this reason, the destruction of the living environment of animals and plants can be suppressed, and the natural environment can be protected. The same applies to the above dam.

Next, another decorative mold 1 according to the present invention will be described. FIG. 13 is an exploded perspective view showing a main part of a decorative form for a retaining wall using a decorative form material according to another embodiment of the present invention as viewed from the back. In the figure, the same reference numerals and symbols as those in the above embodiment are the same as or equivalent to those in the above embodiment.

The decorative mold 10 for retaining wall of this embodiment is also obtained by assembling a plurality of decorative mold materials 1 in the same manner as in the above embodiment. The procedure for assembling the decorative formwork 1 and the structure of the decorative formwork 10 for the retaining wall, and the method of constructing the dam and the retaining wall are substantially the same as in the above embodiment, but the structure of the decorative formwork 1 is slightly different.

As shown in FIG. 13, the decorative formwork member 1 of this embodiment has a connecting plate member made of a steel plate on the back surface of the decorative formwork front member 2 in which three pieces of the wooden bar 2a are overlapped with the longitudinal direction thereof set to be horizontal. 7
Are fixed by the fixing member 4. That is, a connecting plate member 7 made of a steel plate is used as a connecting member for connecting the wood bars 2a instead of the connecting bar 3 made of a wooden bar.

The decorative formwork front member 2 of the decorative formwork 1 has the same structure as that of the above embodiment, but the connecting plate 7 as the connecting member has a width of about 10 cm and a length of about 50 cm. It is a metal plate, the longitudinal direction of which is vertical and the decorative formwork surface member 2
Wood stick 2 at a position about 10 cm inside from the left and right ends of
It is fixed by the fixing member 4 in a state orthogonal to a. The connecting plate 7 protrudes upward and downward from the decorative form surface member 2a by about 10 cm each, and a screw hole 7a is formed substantially at the center of the protruding portion.

The connecting portion between the decorative form surface member 2 and the connecting plate 7 is provided with a hole penetrating the wood bar 2a and the connecting plate 7 at the center of the portion where each of the wood bars 2a and the connecting plate 7 overlap. Has been established. And the bolt 4a
Is inserted from the front, and is fixed by tightening a nut 4c from the front end of the bolt 4a via a washer 4b.

The portion where the fixing member 4 of each wood rod 2a is provided is provided with a recess 6 having a depth of about 5 cm as in the above embodiment, but the screw rod 4d is provided from the back. The difference is that they do not protrude long.

Therefore, the decorative form 10 for a retaining wall made of the decorative form 1 of the present embodiment not only exhibits the same operation and effect as the above-mentioned embodiment, but also at any position of the connecting plate 7 at the time of construction. Since the back support member 13 can be fixed by welding, it can flexibly cope with construction work. Further, by driving a nail into a screw hole 7a provided at a portion where the connecting plate member 7 protrudes, the decorative form member 1 assembled vertically can be more firmly fixed. In particular, in the present embodiment, a concave portion having a thickness of the connecting plate 7 is provided on the back surface of the decorative frame front member 2, and the connecting plate member 7 is fitted into the concave portion, so that the rear surface of the decorative frame front member 2 is flat. Since the surfaces are flush, it is extremely easy to calculate the capacity of the concrete to be poured into the back of the retaining wall formwork 10 during construction.

By the way, in each of the above-described embodiments, the case where the decorative formwork 10 for the retaining wall is formed by using the decorative formwork 1 has been described. The same appearance can be ensured even when stretched on a wall surface. For example, if the decorative form material 1 is retrofitted on the wall surface of a building having a reinforced concrete structure, the appearance becomes a wooden building, and a novel impression can be given in terms of design. In this case, it goes without saying that the decorative mold material 1 may be used as the mold. Particularly, when the decorative form material 1 is stretched, if the decorative form material 1 as shown in FIG. 13 is used, the back surface of the decorative form surface member 2 is flat. Can be.

As described above, the decorative formwork material according to the first aspect of the present invention can utilize wood rods as scrap materials other than long wood rods having a useful value. Since it can be used and the form material has a simple structure, it can be manufactured very easily and suitable for mass production, so that it can be provided at a relatively low cost. In particular, since the end of the connecting member protrudes from above and below the decorative form surface member, a plurality of decorative form materials can be connected very easily.

In the decorative mold for retaining wall according to the second aspect of the present invention, it is not necessary to remove the form, the surface of the retaining wall is not exposed to concrete, and the appearance of the retaining wall is as if wood rods are stacked as a whole. Because it can be made to look like it has been built, it is very familiar to the surrounding natural environment in appearance and does not spoil the natural landscape.

According to the third aspect of the present invention, there is provided a method for constructing a decorative formwork for a retaining wall, in which the retaining wall looks as if it were constructed by stacking wood rods as a whole, and it is not necessary to remove the formwork after completion. Since the form material is not wasted, the labor of the operation can be saved, and the resources can be effectively used. In addition, since relatively high precision for finishing the surface flat as in the related art is not required, preparation for construction and construction can be completed in a short period of time. Further, since a living environment close to the embankment wall made of soil, stone, and the like, which has been used as a living space for animals and plants, can be provided, destruction of the living environment of animals and plants can be suppressed, and the natural environment can be protected.
