[0001]

TECHNICAL FIELD OF THE INVENTION The present invention relates to a concrete formwork for forming a decorative pattern, for example, a concrete form on which a decorative pattern such as a masonry pattern is formed on a retaining wall of a river revetment, a retaining wall of a residential land development site, a retaining wall of a steep slope, and the like. Used when constructing walls,
The present invention relates to a concrete formwork for forming a decorative pattern.

[0002]

[Technical background of the invention] When constructing concrete walls on river revetment retaining walls, residential land development walls, steep slope retaining walls, etc., do not impair the living environment and natural environment so as not to emphasize the inorganic concrete ground surface. Therefore, decorative patterns such as masonry patterns are often formed on the surface of concrete walls.

When constructing a concrete wall with a decorative pattern, a decorative pattern forming form formed by inverting a decorative pattern such as a masonry pattern is attached to one of a pair of concrete placing forms. Concrete is cast between the decorative pattern forming mold and the other concrete casting mold, whereby a decorative pattern such as a masonry pattern is formed on the surface of the concrete wall.

The decorative pattern forming frame is composed of a large number of unit blocks each formed by inverting a masonry pattern. When forming a masonry pattern using this unit block, first, there is a seam between the unit block and an adjacent unit block, but it is necessary to make this seam inconspicuous. Second, it is necessary to form the joint between the stone to be formed and the adjacent stone deeper and wider toward the outside. Third, there is a demand to increase the size of the formed stone, and the situation is that the inverted pattern of the stone in each unit block must be as large as possible.

[0005] Fourth, the most difficult point in this regard is that there is a demand that the formed masonry pattern should not have a monotonous repetitive pattern but an atmosphere of a random pile of natural stones. Finally, fifth, when creating the atmosphere of natural stone, the on-site workers can arrange the unit blocks randomly instead of arranging them based on the arrangement diagram of the unit blocks, thereby reducing work on site. There are also requests to do so.

[0006] As described above, there are various demands for forming a masonry pattern, and a mold for forming a decorative pattern satisfying all of these demands has not been provided.

[0007]

The purpose of the present invention is to satisfy the various demands described above, and specifically,
The seams of the unit blocks can be made inconspicuous, the stones formed can be made large, the formed masonry pattern can be made not a monotonous repetitive pattern, but an atmosphere of natural stone piled up and a random piled pattern can be created. Another object of the present invention is to provide a concrete formwork for forming a decorative pattern, which can reduce the number of operations in the step.

[0008]

SUMMARY OF THE INVENTION 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 random piled masonry pattern on a concrete ground when placing concrete. The concrete formwork is composed of a number of unit blocks, and each unit block is composed of one unit of a rectangular shape of 2 units × 3 units,
And, as shown in the drawing, the unit block has
Independent inverted masonry patterns are formed, and two 1 × 1 unit square notches are formed at a pair of opposing corners of the unit block, and a gap is formed between the unit blocks. This is a decorative form forming concrete formwork for forming a random pile masonry pattern, which is randomly and sequentially arranged so as not to be formed.

Further, the decorative form according to the present invention is

G formwork.

As described above, the unit block is not square or rectangular, but two obliquely opposed corners of the rectangular unit block are formed with two square notches of 1 unit × 1 unit. It is possible to combine these unit blocks at random because it does not have the atmosphere of regularly piled stones, the stonework pattern is not a monotonous repetitive pattern, but the atmosphere of random piled natural stones Can be served. Therefore, by merely arranging several types of unit blocks having different stone patterns at random, an atmosphere in which natural stones are piled up can be obtained while avoiding repeated patterns. This allows the on-site worker to simply arrange the unit blocks at random, thereby reducing the on-site work.

Further, since the unit blocks are formed in a Z-like shape, the seams between the unit blocks do not line up in a straight line, and the seams can be made inconspicuous. Further, since the unit block is not square or rectangular, the degree of freedom in arranging the stones is large, and the stone to be formed can be made larger than when the unit block is quadrangular.

Such a substantially Z-shaped unit block 10
As shown in FIG. 1, the adjacent unit blocks 10 can be combined with each other such that the adjacent unit blocks 10 are arranged in the cutout portions 11. Thus, only by arranging several types of unit blocks 10 at random, there is no atmosphere in which stones are regularly piled up, the masonry pattern is not a monotonous repetitive pattern, and an atmosphere in which natural stones are adjacent to each other, that is, natural stones. You can get the atmosphere of the pattern of piling up.

In addition, when creating the atmosphere of the natural stone pattern, it is not necessary to prepare many types of unit blocks and randomly arrange them.
Just by arranging at random, you can create an atmosphere of natural stones. Therefore, the on-site worker only needs to arrange several types of unit blocks at random, so that the on-site work can be reduced.

Further, as is apparent from FIG. 1, since the unit blocks 10 are formed in a substantially Z-shape, the seams between the unit blocks do not line up in a straight line, and the seams stand out. Can not be.

Furthermore, since the unit blocks are not square or rectangular, the degree of freedom in arranging the stones is large, and the stones formed can be made larger than in the case where the unit blocks are square.

The inverted pattern of the stone shown in the unit block 10 of FIG. 1 is merely an example, and the inverted pattern of the stone is not limited to the illustrated one. In addition, the inverted pattern of the decorative pattern forming formwork according to the present invention is not limited to a stone pattern, but may be various patterns such as a brick pattern.

Next, concrete is cast between the unit blocks 10 and the concrete casting mold 3. Finally, the form ties 5 and 7 are loosened, and the bolts 4 and 6 are cut at predetermined positions to remove the unit blocks 10 and the concrete casting forms 2 and 3. This makes it possible to construct a concrete wall with a masonry pattern, which is an atmosphere of a random pile of natural stones. In addition, it is a matter of course that the construction method of the formwork of the present application is not limited to the above-described example.

[0029]

As described above, according to the present invention, two rectangular notches of 1 unit × 1 unit are formed at a pair of diagonally opposite corners in a rectangular unit block. For this reason, these unit blocks can be randomly combined, whereby an atmosphere of a natural pile of natural stones rather than an atmosphere of regularly piled stones can be obtained. Therefore, by merely arranging several types of unit blocks having different stone patterns at random, an atmosphere in which natural stones are piled up can be obtained while avoiding repeated patterns. This allows the on-site worker to simply arrange the unit blocks at random, thereby reducing the on-site work.

Furthermore, since the unit blocks are formed in a Z-shape, the seams between the unit blocks do not line up in a straight line, and the seams can be made inconspicuous. Further, since the unit blocks are not square or rectangular, the degree of freedom in arranging the stones is large, and the stones formed can be enlarged.
