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.

[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 consists of a number of unit blocks, each unit block consists of one type of rectangular unit of 2 units × 3 units, and a pair of diagonally opposed corners of this unit block has 1 unit × 1 unit. It is characterized in that two square notches are formed.

In the second aspect, the unit block is composed of two types, that is, a rectangular unit of 2 units × 3 units and a square unit unit of 1 unit × 1 unit, and diagonally faces each other in the rectangular unit block. Two 1-unit × 1-unit square notches are formed at the pair of corners.

As described above, the unit block is not in the shape of a square or a rectangle, but in a pair of diagonally opposed corners of a rectangular unit block, two square cutouts of 1 unit × 1 unit are provided. Because they are formed, these unit blocks can be randomly combined, which does not create an atmosphere in which stones are regularly piled up, and the stonework pattern is not a monotonous repeating pattern, but a random piled pattern of natural stones. You can create an atmosphere. Therefore, by simply arranging several types of unit blocks with different stone patterns at random, it is possible to avoid repeating patterns and create an atmosphere of piled natural stones. As a result, on-site workers only need to randomly arrange the unit blocks, which reduces the on-site work.

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

[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 unit blocks 10 and 20 of a concrete formwork for forming a decorative pattern according to a first embodiment of the present invention.

In this embodiment, the unit block 10 is formed in a rectangular shape of 2 units × 3 units, and a pair of diagonally opposite corners of the unit block 10 has a square of 1 unit × 1 unit. Two notches 11 are formed. That is, it is formed in a substantially Z shape. The unit length "1" here is actually preferably 1 shaku (33,3 cm), and may be about 30 to 40 cm.

Such substantially Z-shaped unit blocks 10 can be combined with each other by arranging the adjacent unit blocks 10 in the cutout portion 11 as shown in FIG. As a result, simply arranging several kinds of unit blocks 10 randomly does not create an atmosphere in which stones are regularly piled up, and the stonework pattern is not a monotonous repeating pattern, that is, an atmosphere in which natural stones are adjacent to each other, that is, It is possible to create an atmosphere of piled natural stones.

Moreover, in order to create an atmosphere of this natural stone's piled up pattern, it is not necessary to prepare many kinds of unit blocks and arrange them in a random manner, but simply arrange several kinds of unit blocks 10 in a random. , You can create an atmosphere of natural stones. Therefore, the workers on the site only need to randomly arrange several types of unit blocks, which can reduce the work on the site.

Further, as is clear from FIG. 1, since the unit block 10 is formed in a substantially Z-shape, the seams between the unit blocks are not aligned in a straight line, and the seams are not joined. You can make it less noticeable.

Further, since the unit block is not square or rectangular, the degree of freedom in arranging stones is large, and the stones formed can be made larger than when the unit block is quadrangular.

The stone reversal pattern shown in the unit block 10 of FIG. 1 is merely an example, and it goes without saying that the stone reversal pattern is not limited to the one shown. Further, the reversal pattern of the form for forming a decorative pattern according to the present invention is not limited to a stone pattern, and it goes without saying that various patterns such as a brick pattern may be used.

Next, referring to FIG. 2, a decorative pattern forming mold according to a second embodiment of the present invention will be described. FIG. 2 is a plan view showing a unit block 10 of a concrete formwork for decorative pattern formation according to the second embodiment.

In this embodiment, strictly speaking, there are two types of rectangular unit blocks 10. That is, the unit block 10-1 has a shape in which the unit block 10 is turned upside down. Therefore, when these two types of rectangular unit blocks 10 and 10-1 and the above-mentioned square unit block 20 are randomly combined, various combined arrangements can be taken, as shown in FIG. ..

Therefore, in the case of this embodiment, the unit blocks 10 and 10-1 can be randomly combined twice as compared with the first embodiment of FIG. Various arrangements can be taken. As a result, it is possible to create an atmosphere in which stones are not piled up regularly, and the stonework pattern is not a monotonous repeating pattern, but is a piled up pattern of natural stones. Other functions and effects are similar to those of the first embodiment.

Next, with reference to FIG. 3, a decorative pattern forming mold according to a third embodiment of the present invention will be described. FIG. 3 is a plan view showing the unit blocks 10 and 20 of the concrete formwork for decorative pattern formation according to the third embodiment.

In this embodiment, a square unit block 20 of 1 unit × 1 unit is used in addition to the substantially Z-shaped unit block 10 described above. The unit block 20 is arranged in the cutout portion 11 of the unit block 10.

In particular, in the present embodiment, since the unit block 20 is used, as is apparent from FIG. 2, there are many combinations of patterns, and various combinations are possible as compared with the embodiments of FIGS. Random combinations can be realized.

Therefore, in the present embodiment, compared with the embodiment of FIGS. 1 and 2, the masonry pattern is not a monotonous repeating pattern, and the atmosphere is such that natural stones are adjacent to each other, that is, natural stones are piled up. It is possible to create an atmosphere of random patterns. Other functions and effects are the same as those of the first and second embodiments of FIGS.

Next, the configuration of the unit blocks 10 and 20 will be described with reference to FIG. Each of the unit blocks 10 has a recess 21 formed by reversing the outer shape of the natural stone, and a joint for forming a joint of a masonry pattern so as to partition the recess 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, an outer peripheral joint 24 is also formed on the outer peripheral portion of each block. If the outer peripheral joint 24 is formed to be narrower than the joint portion 22 (for example, approximately 1/2), the finished appearance will be good.

Next, an example of the construction of the decorative pattern forming concrete form frame configured as described above will be described with reference to FIG. First, the unit blocks 10 are 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 bolts 4 are screwed into the form ties 5 to fix the unit blocks 10 ... to the concrete pouring formwork 2, while the bolts 7 fixed to the other concrete pouring formwork 3 with the form ties 6 are used. , The bolt 4 is connected by a cap nut 8.

Next, concrete is cast between the unit blocks 10 ... And the concrete casting formwork 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 pouring formwork 2 and 3. As a result, it is possible to construct a masonry concrete wall, which is an atmosphere of random piled up natural stones. Needless to say, the method for constructing the formwork of the present application is not limited to the above-described example.
