BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining wall mold, and in particular, it can be used as a retaining wall mold for dams and the like, and can also be used as it is as a decorative material for the retaining wall surface. The present invention relates to a frame material, a decorative form for a retaining wall, and a construction method thereof.

2. Description of the Related Art Conventionally, concrete retaining walls have been used for dams and river embankments that are constructed to stop water currents and sediments across rivers and valleys, or on slopes that are slopes beside roads. This kind of concrete retaining wall is constructed in various places including the mountainous area for the purpose of preventing landslides. It also plays a role in ensuring the daily safety of the surrounding area and minimizing damage in the event of a natural disaster.

Further, concrete is mainly widely used for the dam and the concrete retaining wall constructed for such a purpose. For example, when constructing a weir, first construct a concrete foundation on the ground where the dam or river is to be constructed, then assemble a formwork according to the outer shape of the weir to be constructed, Concrete is poured into the frame, and after a lapse of a predetermined time, the form is removed to build a dam. In addition, slopes on the side of the road and concrete retaining walls on river banks are constructed in a similar way.

[0004]

The above-mentioned dam or concrete retaining wall has usually been constructed in a natural environment as indicated by its purpose. However, since it is constructed of concrete and the surface of the concrete is exposed, the appearance is unnatural and does not match the surrounding natural environment, impairing the natural landscape.

Further, in particular, in the concrete retaining wall of the river embankment, while the safety of the surrounding area is provided, it is extremely difficult for the flora and fauna to live by turning from the embankment wall which was conventionally formed of earth and sand and stones. It was a concrete retaining wall. Therefore, as a result, the living environment of many plants and animals whose natural levee is their living place was destroyed, leading to the destruction of the natural environment. The same applies to dams and concrete retaining walls beside the road.

Furthermore, in the case of constructing a dam or a concrete retaining wall, a relatively large-scale construction is carried out to construct the dam or the concrete retaining wall, and the finished product is large, so Since the assembly and removal of the concrete panel is indispensable, the work was troublesome.
Moreover, since relatively high accuracy is required when assembling the concrete panel to finish the surface flat, the work is further troublesome. In addition, the concrete panels used for the formwork were discarded after they were removed, which was a waste of resources.

Therefore, the present invention does not impair the effects of conventional dams and concrete retaining walls at all, and even when constructed in a natural environment, it matches well with the surrounding landscape and also creates natural levee life. The living environment of many flora and fauna in the place can be protected, and the construction can be completed by an extremely simple work, and the effective use of resources can be achieved with a decorative frame material and a retaining wall decorative frame and its The task is to provide a construction method.

The connecting portion between the decorative form surface member 2 and the connecting rod 3 penetrates the wooden rod 2a and the connecting rod 3 at the center of the portion where the wooden rods 2a and the connecting rod 3 intersect and overlap with each other. Holes are bored. Then, from the back side, the bolts 4 are inserted into the holes of the wood rod 2a and the holes of the connecting rod 3 located above and below.
a is inserted, and is fixed from the front by tightening a nut 4c from the tip of a bolt 4a via a washer 4b. Further, a screw rod 4d is inserted into the hole of the wood rod 2a and the hole of the connecting rod 3 located at the center, and the nut 4c is tightened from the back face via the washer 4b, and the long nut 12a is attached from the front face via the washer 4b. It is fixed by tightening. In this way, the wood rods 2a are fixed to three positions of the single connecting rod 3 by the fixing member 4 including the bolt 4a, the washer 4b, the nut 4c, the long nut 12a, and the screw rod 4d.

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 is like this. The fixing member 4 for fixing the wood rod 2a and the connecting rod 3 located above and below is a fixing member having a thickness of the washer 4b and the nut 4c and a length of the bolt 4a protruding from the washer 4b by about 1 Cm to 2 Cm. The protrusion amount is 4. That is, it only projects about 2 Cm to 6 Cm from the back surface of the decorative mold surface member 2a. A fixing member 4 for fixing the wood rod 2a and the connecting rod 3 located in the center is inserted with a screw rod 4d of a predetermined length, and a nut 4c is tightened from the back side via a washer 4b.
It is fixed by tightening a long nut 12a from the front side through a washer 4b, and a screw rod 4d is in a protruding state on the rear face of the connecting rod 3. After completion, as will be described later, a mortar of the same color as the wood, a cork mixed with an adhesive, or a sealing material 5 such as wood chips is embedded in the recess 6 provided on the surface of each wood rod 2a, and the fixing member 4 is attached from the surface. Is processed so that it cannot be seen.

The wood rods 2a constituting the decorative form surface member 2 do not need to have a curved surface, and may be simply timbers. The connecting rod 3 that supports the decorative form frame member 2 from the back side does not necessarily have to protrude from the upper and lower sides of the decorative form face member 2, and may be protruded from one side or different sides. The number of connecting rods 3 need not be two, and may be three or more as long as they can be assembled vertically and horizontally.
The material of the wood rod 2a is not limited to cedar wood or larch wood,
Any kind of wood may be used, and any size may be used as long as it can be assembled vertically and horizontally. Further, although it is not always necessary to apply antiseptic / insectproof treatment to the wood, it is preferable to perform antiseptic / insecticide treatment in order to maintain the state at the time of construction for a long period of time.

Then, according to the area and shape of the retaining wall to be constructed, the decorative frame material 1 is further assembled vertically and horizontally as described above. Next, the external appearance of the retaining wall decorative frame 10 thus assembled will be described. FIG. 4 is a front view of a main part showing an assembled state of a retaining wall decorative form that is an embodiment of the present invention,
FIG. 5 is a rear view of essential parts showing an assembled state of the decorative form for a retaining wall which is an embodiment of the present invention.

As shown in FIG. 4, when the decorative form 10 for the retaining wall of the present embodiment is viewed from the front side, for example, the decorative form material 1 shown by the solid line will be mainly described, and shown by the solid line. Decorative form frame members 1 of the same shape are arranged on the left and right of the decorative form frame member 1, and the decorative form frame members 1 are vertically arranged so that the abutting portions of the arranged decorative form frame members 1 are on the vertical center line. 1 touches. The connecting rod 3 fixed to the back surface of the decorative formwork table member 2 is hidden behind the decorative formwork surface member 2, and only the decorative formwork surface member 2 is lined up from the front surface. become.

On the other hand, as shown in FIG. 5, when the retaining wall decorative formwork 10 of this embodiment is viewed from the back side, it is fixed to the backside of the decorative formwork material 1 assembled vertically, horizontally and adjacently. The projecting portions of the connecting rod 3 cover the back surfaces of the upper and lower decorative formwork front members 2. Therefore, at the upper part of the back surface of the decorative formwork front member 2 shown by the solid line, the two decorative formwork materials 1 placed on
The projecting portions of the left and right connecting rods 3 are covered, and similarly, the lower portions are covered by the projecting portions of the left and right connecting rods 3 of the two lower decorative frame materials 1. On the contrary, the protruding portion of the connecting rod 3 of the decorative frame material 1 shown by the solid line covers the back surface of the decorative frame surface member 2 of each of the upper and lower decorative frame materials 1. further,
In such a state, they are continuously assembled vertically and horizontally.

As shown in FIG. 5, the upper and lower decorative frame members 1 are fixed by striking the support plate 8 across the upper and lower back surfaces of the assembled decorative frame member 1, The decorative frame materials 1 can be more firmly fixed to each other. Thus, by fixing the upper and lower decorative frame members 1 with the support plate 8, it is possible to prevent the decorative frame member 1 from floating when concrete is poured.

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

Next, a construction method for actually constructing a dam by using the retaining wall decorative formwork 10 of this embodiment will be described. FIG. 6 is a side view showing a case of constructing a dam using the decorative form for a retaining wall which is an embodiment of the present invention, and FIG. 7 uses the decorative form for a retaining wall which is an embodiment of the present invention. FIG. 8 is a front view showing the outer appearance of the dam, FIG. 8 is a rear perspective view showing the decorative frame material located at the lowermost end of the retaining wall decorative frame of FIG. 7, and FIG. 9 is a retaining wall which is an embodiment of the present invention. It is a principal part expanded sectional view which shows the assembled state of a decorative formwork.

When constructing a dam using the retaining wall decorative formwork 10 of this embodiment, it is constructed sequentially through predetermined steps. For example, as shown in FIG. 6, construction is performed in three steps within the range of A to C. In this case, first, the foundation 11 for the dam is constructed with concrete. At that time, the support pile 13a such as a reinforcing bar is embedded in the foundation 11 so as to project from the upper surface,
As shown in the portion A, on the surface of the base 11 which is slightly inclined, the back surface of the decorative frame material 1 for exclusive use of the base portion is in contact with the surface of the base 11, and a screw rod 4d which is projected to the back side is long.
Is embedded in the foundation 11 as an anchor member. Then, from the surface of the decorative frame material 1, the decorative frame material 1 is supported by the surface support member 12 formed of each tube or the like.

After the foundation 11 is completed, as shown in the portion B, the decorative frame material 1 dedicated to the foundation 1
The ordinary decorative frame materials 1 described with reference to FIGS. 1 to 5 are sequentially stacked above the above. Here, as shown in the portion B, the decorative frame members 1 are assembled by stacking them in five stages. In other words, since one decorative form material 1 constitutes the decorative form surface member 2 with three wood rods 2a each, the wood rods 2a with 15 cross sections are provided.
Are piled up. At the same time, each decorative form material 1
The decorative frame material 1 is supported from the surface by a surface support member 12 such as tubes. Further, the screw rod 4d protruding long from the back side of the decorative frame material 1 and the support pile 13a are fixed by the back support member 13 made of a reinforcing bar, and each decorative frame material 1 is supported from the back surface. The screw rod 4d and the support pile 13
The 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 base of the support pile 13a are connected by the back support member 13, the strength is increased and each decorative form material 1 can be supported in a relatively stable state. In this way, when the assembling and supporting of the retaining wall decorative formwork 10 is completed, concrete is driven up to the position of the two-dot chain line of the portion B, and similarly to the case of the foundation 11, the support pile 13a is embedded in the concrete upper surface.

Further, when the concrete in the portion B has hardened, the decorative frame materials 1 are further stacked in order as shown in the portion C. Each of the decorative frame materials 1 assembled by stacking four layers is supported from the surface by a surface support member 12, and the decorative frame material 1 is viewed from the front.
And the screw bar 4d projecting long from the back side of the decorative frame material 1 and the support pile 13a are fixed by the back support member 13 such as a reinforcing bar. Then, when the assembling and supporting of the retaining wall decorative formwork 10 is completed, concrete is poured to the position of the two-dot chain line in the portion C, and after the concrete is solidified, the surface support member 12 is removed and the upper part of the dam is removed. In order to cut and align the retaining wall decorative formwork 10 and to hide the fixing member 4 on the surface of each wood rod 2a, in the recess 6 of each wood rod 2a, a mortar of the same color as the tree or a cork or wood chips of an adhesive mixture The filling material 5 is embedded and the dam is completed.

Therefore, the appearance of such a dam looks as if it was constructed by stacking the wood rods 2a on the whole, as shown in FIG. 7, so that the appearance is very familiar to the surrounding natural environment and naturally. Does not spoil the landscape. In addition,
As the decorative form material 1 located in the inclined portion at the center of the dam, a decorative form surface member 2 cut according to the inclination is used.

Further, the decorative frame member 1 dedicated to the basic portion described above has a decorative frame surface member 2a as shown in FIG.
As a connecting member fixed to the back surface of the, a connecting plate member 7 made of metal and having a width of about 5 Cm and a length of about 40 Cm is used. The metallic connecting plate member 7 projects above the decorative form frame member 2 and the back surface of the decorative form member 2a is recessed by the thickness of the connecting plate member 7 to form a concave shape. The connecting plate member 7 is fitted. Therefore, the back surface of the decorative frame material 1 dedicated to the base portion is provided with the decorative frame front member 2
And the metal connecting plate 7 as the connecting member are 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 having a length of about 4 Cm and a relatively short screw rod having a length of about 3 Cm to 6 Cm. 12b, a substantially V-shaped fixing member 12d made of metal,
Using the wedge member 12e for inserting into the hole of the fixing member 12d, the support rod 12c made of a steel pipe such as a square tube is used.
Are assembled vertically and horizontally in a grid pattern. That is, when the decorative frame material 1 is supported by the surface support member 12, the screw rod 4b protruding inside the concave portion 6 of the middle wooden rod 2a forming the decorative frame surface member 2 of the decorative frame material 1 Is a long nut 12
a is screwed, and the threaded 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, and the V-shaped fixing member 12d is a support rod assembled in a lattice shape by a wedge member 12e. It is fixed in contact with the surface of 12c.

When the driven concrete is solidified and the surface support member 12 is to be removed, the wedge member 12e is removed from the V-shaped fixing member 12d so that the lateral support 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 frame material 1, and the surface support member 12 is also reused when the decorative wall frame 10 is constructed.

In the case of constructing a dam using the retaining wall decorative formwork 10, it may be constructed in any number of stages, and the decorative formwork materials 1 to be assembled may be stacked in any number of stages. Further, the front surface supporting member 12 and the rear surface supporting member 13 may be of any material or structure as long as they can support the retaining wall decorative frame 10 from the front surface or the rear surface. further,
In the present embodiment, the direction of the decorative frame material 1 has been described as being assembled with the longitudinal direction of the decorative frame surface member 2 lying sideways, but since it is supported by the front surface support member 12 and the back surface support member 13, It is also possible to assemble in the horizontal direction with the direction being vertical, or in some cases with the longitudinal direction being inclined.

Therefore, the decorative form 10 for the retaining wall constructed by the above-described method looks as if it was constructed by stacking the wooden rods 2a on the whole, and also has the effect of the conventional dam. Since it is not necessary to remove the retaining wall decorative formwork 10 after completion without damaging it, the labor of the work can be saved and the construction can be completed in a relatively short period of time. In addition, since it is not necessary to remove the retaining wall decorative formwork 10, it is not necessary to assemble the concrete panel with relatively high precision to finish the surface flat, unlike a formwork using a conventional concrete panel, that is, Since the surface of the retaining wall decorative frame 10 is made of the wood rods 2a, even if there is some unevenness, the beauty of the appearance is not impaired. Therefore, high precision is not required, and therefore the work is further troublesome. It can be omitted and the construction preparation and construction can be completed in a short period of time.

Next, a construction method for constructing a concrete retaining wall beside the road using the retaining wall decorative formwork 10 of this embodiment will be described. FIG. 10 is a side view showing a case of constructing a slope using a decorative form for a retaining wall which is an embodiment of the present invention, and FIG. 11 is a side view showing a slope using a decorative form for a retaining wall of FIG. It is a front view which shows an external appearance.

Even when a concrete retaining wall on the side of a road is constructed using the retaining wall decorative formwork 10 of this embodiment, it is constructed sequentially through predetermined steps as in the case of constructing the dam. For example, as shown in FIG. 10, a case of performing the construction in three stages D to F will be described. First, the wall surface beside the road is slightly shaved, and the foundation 11 is constructed. At this time,
The support pile 13a made of reinforcing steel is driven into the foundation 11, and the support pile 13a is driven to support the lower end of the retaining wall decorative formwork 10 on the ground as well.

Next, as shown in the portion E, the decorative form material 1
Are sequentially stacked, and the surface of the decorative frame material 1 is covered with the surface support member 12
The decorative form material 1 is supported from the front. At the same time, the screw rods 4d that project long from the back side of the decorative frame material 1 and the support piles 13a are fixed by welding with the rear surface support member 13 made of reinforcing steel, and the decorative frame material 1 is supported from the rear surface. 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 frame material 1 can be supported in a stable state. Then, when the assembling and supporting of the retaining wall decorative formwork 10 is completed, concrete is driven up to the position of the chain double-dashed line in the E portion, and the support pile 13
a is arranged.

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

Therefore, the external appearance of the retaining wall thus constructed looks like a wall surface on which the wooden rods 2a are piled up as a whole, as shown in FIG. Further, the fence 14 is provided on the upper surface of the retaining wall, but the fence 14 is provided for the purpose of preventing falling rocks and may not be necessary in some cases.

By the way, in the above description, the back support member 1
The case where the support piles 13a for 3 are arranged in concrete has been described, but the support piles 13a are buried in the rear cliff surface,
The back support member 13 may be fixed using the support pile 13a.

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

When constructing a concrete retaining wall for a river embankment using the retaining wall decorative formwork 10 of the present embodiment, as in the case of constructing a concrete retaining wall on the side of a road, a predetermined step is taken. To construct. For example, in FIG. 12, 3 from G to I
It is a figure which shows the concrete retaining wall of the river embankment which is constructed | assembled in steps, but the construction method of G part thru | or I part is substantially the same as the said concrete retaining wall by the said roadside.

Therefore, the retaining wall constructed as described above can be used as a conventional embankment wall formed of earth and sand or stone, which is used as a living space for plants and animals, without impairing the effect of the conventional retaining wall. We can provide a close living environment. Therefore, it is possible to suppress the destruction of the living environment of plants and animals and protect the natural environment. The same applies to the above dam.

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

The retaining wall decorative formwork 10 of this embodiment is also an assembly of a plurality of decorative formwork materials 1 as in the above embodiment. The procedure for assembling the decorative frame material 1, the structure of the decorative frame 10 for the retaining wall, and the method of constructing the dam or retaining wall are substantially the same as those in the above-mentioned embodiment, but the structure of the decorative frame material 1 is slightly different.

As shown in FIG. 13, the decorative form material 1 of this embodiment is a connecting plate member made of a steel plate on the back surface of the decorative form surface member 2 in which three wood rods 2a are laid side by side in the longitudinal direction. 7
Is fixed by the fixing member 4. That is, instead of the connecting rod 3 made of a wood rod, the connecting plate member 7 made of a steel plate is used as a connecting member for connecting the wooden rods 2a.

The decorative form frame member 2 of the decorative form material 1 has the same structure as that of the above embodiment, but the connecting plate member 7 as the connecting member has a width of about 10 Cm and a length of about 50 Cm. This is a metal plate, the longitudinal direction of which is vertical, and the decorative form surface member 2
Wood rod 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 of being orthogonal to a. The connecting plate member 7 is vertically projected from the decorative form frame member 2a by about 10 cm each, and a screw hole 7a is formed substantially at the center of the projecting portion.

Further, at the connecting portion between the decorative form surface member 2 and the connecting plate member 7, a hole penetrating the wooden rod 2a and the connecting plate member 7 is formed at the center of the portion where the respective wooden rods 2a and the connecting plate member 7 overlap. It is set up. The bolt 4a is inserted into the hole from the rear side.
Is inserted, and the nut 4c is fixed from the front end of the bolt 4a via the washer 4b from the front end.

Similar to the above-mentioned embodiment, a recess 6 having a depth of about 5 cm is provided at the portion of each wood rod 2a where the fixing member 4 is provided, but the screw rod 4d is provided from the rear surface. The difference is that it does not project for a long time.

Therefore, the retaining wall decorative frame 10 made of the decorative frame member 1 of this embodiment has the same effects as the above-described embodiment, and at the time of construction, it can be placed at any position of the connecting plate member 7. Since the back support member 13 can be fixed by welding, it can flexibly cope with the construction work. Further, the decorative frame material 1 assembled vertically can be more firmly fixed by driving a nail into the screw hole 7a provided in the protruding portion of the connecting plate material 7. Particularly, in the present embodiment, a concave portion having the thickness of the connecting plate member 7 is provided on the back surface of the decorative form frame front member 2, and the connecting plate member 7 is fitted in this concave portion, so that the rear surface of the decorative form frame front member 2 is flat. Since the surfaces are flush with each other, it is extremely easy to calculate the capacity of the concrete to be cast on the back surface of the retaining wall decorative formwork 10 during construction.

By the way, in each of the above-mentioned embodiments, the case where the decorative frame material 1 is used to form the decorative wall decorative frame 10 has been described. Even if it is stretched on the wall surface, the same appearance can be ensured. For example, if the decorative form material 1 is stretched on the wall surface of a building having a reinforced concrete structure, the building becomes a wooden structure with an external appearance, and a novel impression can be given in terms of design. In this case, it goes without saying that the decorative form material 1 may be used as the form. In particular, when the decorative frame material 1 is stretched, if the decorative frame material 1 as shown in FIG. 13 is used, the rear surface of the decorative frame front member 2 is flat, so that the decorative frame material 1 can be stretched very easily. You can

As described above, the decorative frame material of the invention of claim 1 can utilize wood rods as end materials other than long-use wood rods having a useful value. It can be used, and since the form material has a simple structure, it can be manufactured extremely easily and is suitable for mass production, so that it can be provided at a relatively low cost.

In the retaining wall decorative formwork according to the second aspect of the present invention, it is not necessary to remove the formwork, the retaining wall surface is not exposed to concrete, and the appearance of the retaining wall is as if the wooden rods were piled up as a whole. As it can be made to look like it is built, it is very familiar to the surrounding natural environment and does not spoil the natural landscape.

According to the method of constructing a decorative formwork for a retaining wall of the invention of claim 3, the retaining wall surface looks as if it was constructed by stacking wood rods on the whole, and it is not necessary to remove the formwork after completion. Since the formwork material is not wasted, the labor of the work can be saved and the resources can be effectively used. Further, since relatively high accuracy for finishing the surface flat as in the conventional case is not required, the construction preparation and construction can be completed in a short period of time. Furthermore, since it is possible to provide a living environment close to a conventional embankment wall formed of earth and sand or stone, which is used as a living space for animals and plants, it is possible to suppress the destruction of the living environment of animals and plants and protect the natural environment.
