[Technical background of the device]

 When constructing concrete walls for river revetment retaining walls, residential land development retaining walls, steep slope retaining walls, etc., in order not to emphasize the inorganic concrete surface and not to damage the living environment and natural environment, concrete walls A lot of decorative patterns, such as masonry patterns, are formed on the surface of stones.

When constructing this concrete wall with a decorative pattern, a decorative pattern forming frame in which a decorative pattern such as a masonry pattern is reversed is attached to one of a pair of concrete placing frames, Concrete is placed between the formwork for forming a decorative pattern and the other formwork for placing concrete, whereby a decorative pattern such as a masonry pattern is formed on the surface of the concrete wall.

By the way, this decorative pattern forming frame is composed of a large number of unit blocks each having a masonry pattern inverted. When forming a masonry pattern using this unit block, firstly, there is a seam between the unit block and the adjacent unit block, but it is necessary to make this seam inconspicuous. Second, it is necessary to form the joint between the formed stone and the adjacent stone deeper and wider toward the outside. Thirdly, there is a desire to make the stones that are formed larger, and the situation is that the inverted pattern of stones in each unit block must be made as large as possible.

Further, as a fourth point, although this point is the most difficult, there is a demand for creating an atmosphere of a piled-up pattern in which natural stones are piled up, instead of a monotonous repeating pattern in the formed stone pattern. .. Finally, fifth, when creating the atmosphere of this natural stone, the workers at the site can arrange the unit blocks randomly instead of arranging them based on the layout of the unit blocks, and There is also a desire to reduce it.

As described above, various demands have been made in forming a masonry pattern, and hitherto, a decorative pattern forming frame that satisfies all of these demands has not been provided.

[0007]

[The purpose of the device]

 The present invention has been made in order to satisfy the above-mentioned various demands. Specifically, the seams of unit blocks can be made inconspicuous, and the stones formed can be made large and formed. To provide a concrete formwork for decorative pattern formation that can create an atmosphere of a piled up pattern of natural stone instead of a monotonous repeating pattern of the masonry pattern and also reduce the work on site. is there.

[0008]

[Outline of the device]

 In order to achieve this object, a concrete formwork for forming a decorative pattern according to the present invention is a concrete formwork for forming a decorative pattern for forming a decorative pattern on a concrete surface when concrete is poured. The frame is composed of a large number of unit blocks, the outer shape of the unit block is a hexagon, and a large number of hexagonal unit blocks are arranged.

Since the unit blocks are formed in a hexagonal shape, the joints between the unit blocks can be seen as joints, and the joints can be made inconspicuous. Further, since the unit block is not square or rectangular but hexagonal, the stone formed can be made larger than when the unit block is square or the like. Hexagons are also considered to have a shape close to a circle, which makes them suitable for making round stones.

Furthermore, since the unit block can be formed into, for example, a regular hexagon, one unit block can be used by rotating it by 60 °, and the number of random arrangement patterns of the unit block can be significantly increased. be able to. Therefore, there is no atmosphere in which stones are regularly piled up, and the stonework pattern is not a monotonous repeating pattern, and an atmosphere in which random stones are piled up can be created.

Further, this makes it possible to create an atmosphere in which natural stones are piled up by avoiding repeated patterns by merely randomly arranging several types of unit blocks having different stone patterns. Therefore, the workers on the site only need to arrange the unit blocks randomly, and the work on the site can be reduced.

[Specific explanation of the device]

 Hereinafter, embodiments according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a unit block 10 of a concrete formwork for forming a decorative pattern according to an embodiment of the present invention.

In this embodiment, as shown in FIGS. 1 to 3, the outer shape of the unit block 10 is a regular hexagon. The length of one side of this regular hexagon is about 45 cm, and may be in the range of 35 to 55 cm. However, it is not limited to this.

2 and 3 show two stone patterns of the unit block 10. As described above, since the unit block 10 has a regular hexagonal shape, a relatively large stone can be formed. Hexagons are also considered to have a shape close to a circle, and are therefore suitable for making round stones. The stone reversal patterns shown in the unit blocks 10 of FIGS. 1 to 3 are merely examples, and it goes without saying that the stone reversal patterns are not limited to those shown in the drawings.

Further, since the unit block 10 is formed in the regular hexagonal shape as described above, one unit block 10 can be used by rotating it by 60 °, and one unit block 10 can be used by others. The unit blocks 10 can be exchanged with each other. Therefore, it is possible to significantly increase the number of random arrangement patterns of unit blocks. As a result, it is possible to prevent the stone masonry pattern from repeating monotonously, and it is possible to sufficiently create an atmosphere of a masonry pattern in which natural stones are piled up.

In connection with this, since the unit block 10 is formed in a regular hexagon, the joint between the unit blocks 10 can also be seen as a joint, and the joint can be made inconspicuous. it can. Moreover, since the seams are not aligned in a straight line, the seams are not noticeable. These things contribute to creating an atmosphere of random patterns.

Moreover, in order to create an atmosphere of the pattern of natural stones being piled up, it is not necessary to prepare a large number of types of unit blocks and arrange them in a random manner. You can create an atmosphere of piled natural stones. Therefore, a worker on the site only needs to randomly arrange several types of unit blocks, which can reduce the work on the site.

Further, in FIG. 1, the partial blocks denoted by reference numerals 10-1, 10-2, and 10-3 respectively include one unit block 10 as shown in FIG. , B, c may be used. However, separately, these partial blocks 10-1, 10-2, 10-3 may be molded using a mold. In order to avoid monotony, it is preferable to cut and use one unit block as described above.

Further, the shape of the unit block 10 according to the present embodiment is not limited to the regular hexagon, and may be an elongated hexagonal shape as shown in FIG. In this case, as is clear from FIG. 4, it is suitable for forming a relatively small stone masonry pattern. As described above, in the present invention, the shape of the unit block 10 is not limited to the regular hexagon, and various hexagonal shapes may be used.

The reversal pattern of the decorative pattern forming frame according to the present invention is not limited to a stone pattern, and may be a brick pattern or other various patterns. Next, the configuration of the unit block 10 will be described with reference to FIG. Each unit block 10 has a concave portion 21 formed by reversing the outer shape of natural stone, and a joint for forming a masonry joint so as to partition the concave portion 21. The part 22 is formed. The joint portion 22 has a cavity 23 inside and also serves as a reinforcing member for the block. Further, since a joint is formed at the boundary between one block and a block adjacent thereto, outer joints 24 are also formed on the outer peripheral portion of each block. If the outer peripheral joint 24 is formed narrower than the joint portion 22 (for example, approximately halved), the appearance of the finish is good.

Next, an example of construction of the decorative form forming concrete form frame configured as described above will be described with reference to FIG. First, the unit block 10 is arranged on one of the pair of concrete casting forms 2 and 3. The bolt 4 inserted through the concrete pouring formwork 2 is pushed into the cavity 23 of the joint portion 22 of the unit block 10 to penetrate the joint portion 22. The bolt 4 is screwed into the form tie 5 to fix the unit block 10 to the concrete placing form 2, while the bolt 7 fixed to the other concrete placing form 3 with the form tie 6, The bolt 4 and the bolt 4 are connected to each other.

Next, a concrete is cast between the unit block 10 and the concrete casting formwork 3. Finally, the form ties 5 and 7 are loosened, the bolts 4 and 6 are cut at predetermined positions, and the unit block 10 and the concrete pouring forms 2 and 3 are removed. As a result, a concrete wall with a masonry pattern, which is an atmosphere of a random pile of natural stones, can be constructed. Needless to say, the method of constructing the formwork of the present application is not limited to the above-described example.

[Effect of the device]

 As described above, in the present invention, since the unit blocks are formed in a hexagonal shape, the joints between the unit blocks can be seen as joints, and the joints can be made inconspicuous. Furthermore, since the unit block is hexagonal, the stone formed can be made larger than when the unit block is square or the like.

Further, since the unit block can be formed in, for example, a hexagon, one unit block can be used by rotating it by 60 °, and the number of randomly arranged patterns of the unit block can be significantly increased. be able to. Therefore, there is no atmosphere in which stones are regularly piled up, and a random pattern of natural stones can be created.

Further, this makes it possible to avoid repeating patterns and create an atmosphere in which natural stones are piled up by simply arranging several types of unit blocks having different stone patterns at random, and the workers at the site can All that is required is to arrange the blocks at random, which can also reduce the work on site.
