Since the unit blocks are formed, the unit blocks can be arranged so that the unit line ( ab ) of one unit block is in contact with the unit line ( cd ) of the adjacent unit block. Can be arranged.

As described above, since the dividing line of the unit block (that is, the seam of the unit block) is configured by the curved line, the seam can be made inconspicuous as compared with the case where the seam is a straight line. .. Further, since the shape of the entire unit block is also defined by the curve, the degree of freedom in arranging stones is large, and the formed stone can be made larger than when the unit block is a quadrangle. In addition, the corners of the formed stone can be made into a gentle curve without making it sharp, and the shape can be made closer to a natural stone.

Since the dividing line (that is, the outer edge) of the unit block is a curve, there is no atmosphere in which stones are regularly piled up, and the formed masonry pattern is not a monotonous repeating pattern, but a random piled pattern in which natural stones are piled up. Can bring out the atmosphere. Furthermore, since the dividing lines (that is, the outer edges) of the unit blocks are curved, it is possible to create an atmosphere in which natural stones are piled up by avoiding repetitive patterns simply by randomly arranging a few types of unit blocks. .. Therefore, the workers on the site only need to randomly arrange the unit blocks, which can reduce the work on the site.

Further, in the second invention according to claim 2, in addition to the first invention, each unit block further includes an intermediate point (e) arranged on the partition line ( ab ) and a partition line ( ab ). A midpoint (f) arranged on the line ( cd ), and a demarcation line ( ae ) that connects the one defined point (a) and the midpoint (e), and one defined point (c) And a dividing line ( cf ) connecting the intermediate point (f) and the dividing line ( cf ) correspond to each other, and a dividing line ( eb ) connecting the intermediate point (e) and one defined point (b) and an intermediate point It is characterized in that the dividing line ( fd ) connecting (f) and one defined point (d) is a curve corresponding to each other.

In the second aspect of the present invention, the seams between the unit blocks are shifted as compared with the first aspect of the present invention, so that the seams can be made less noticeable. Furthermore, since the arrangement of the unit blocks is more random, it is possible to create an atmosphere in which natural stones are adjacent to each other, and to create a random pattern of natural stones.

[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 a first embodiment of the present invention.

In FIG. 1, the unit block 10 has four defined points a, b, c, d. The two defined points a and b are connected by a partition line ab that partitions the outer edge of the unit block. Similarly, the two defined points b and c are connected by a partition line bc , the two defined points c and d are linked by a partition line cd , and the two defined points d and a are linked by a partition line da. ..

Further, the comparting line ab and the comparting line cd , which are in a relationship of facing each other, are composed of gentle curves, and the comparting line bc and the comparting line da are composed of corresponding curves. There is. That is, the dividing line ab and the dividing line cd are formed from almost the same gentle curve, and the dividing line bc and the dividing line da are formed from almost the same gentle curve.

Therefore, in FIG. 1, for example, the demarcation line cd of the unit block 10 can contact the demarcation line ( ab ) above the adjacent unit block 10-1. Similarly, the demarcation line bc of the unit block 10 can contact the demarcation line ( da ) on the left side of the adjacent unit block 10-2. Therefore, a large number of unit blocks 10, 10-1, 10-2, ... According to the present embodiment can be arranged. As a result, the joint can be made inconspicuous as compared with the case where the joint between unit blocks is straight.

Since the demarcation lines ab , bc , cd , and da are formed in a gentle curve in this manner, as is clear from FIG. 1, the degree of freedom in arranging stones is large, and the unit block is a square. The stones formed can be made larger than in the case where Moreover, it is possible to make a gentle curve without making the corners of the stone sharp, and to make the shape closer to a natural stone. 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 that shown.

Further, since the division lines ab , bc , cd , and da of the unit blocks 10, 10-1 ... Are curved lines, there is no atmosphere in which stones are regularly piled up, and an atmosphere in which natural stones are adjacent to each other is created. It is possible to put out, and it is possible to create an atmosphere of a piled up pattern of natural stones.

In addition, it is not necessary to prepare a large number of types of unit blocks and arrange them in a random manner in order to create an atmosphere of the random stones, and at most, a few unit blocks are randomly arranged. Just by arranging them, you can create an atmosphere of piled natural stones. Therefore, a worker on the site only needs to randomly arrange a few types of unit blocks, which can reduce the work on the site.

The inverted 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, with reference 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 forming a decorative pattern according to the second embodiment. In this embodiment, as is clear from comparison between FIG. 1 and FIG. 2, the upper unit blocks 10 and 10-2 are shifted with respect to the lower unit blocks 10-1 and 10-3, whereby It creates a more random atmosphere.

That is, also in the present embodiment, the dividing line connecting the defined points a and b and the dividing line connecting the defined points c and d are almost the same curve. In the present embodiment, each unit block 10 further has an intermediate point e arranged on the division line ab and an intermediate point f arranged on the division line cd , and the upper side of the unit block 10 The partition line ae is formed on the lower parting line cf in almost the same curve, and the upper parting line eb is formed in the lower parting line fd in almost the same curve. As a result, the upper unit blocks 10 and 10-2 can be shifted with respect to the lower unit blocks 10-1 and 10-3.

Therefore, in this embodiment, the seams between the unit blocks are shifted as compared with the first embodiment of FIG. 1, so that the seams can be made more inconspicuous. Furthermore, since the unit blocks are arranged more randomly, it is possible to create an atmosphere in which natural stones are adjacent to each other, creating a random pattern of natural stones.

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

In this embodiment, the curvature of the curve of each partition line is made smaller than that in the second embodiment of FIG. That is, the curve of the dividing line is tightly formed. This case is a preferred embodiment when it is desired to emphasize the roundness of the stone shape. Other functions and effects are the same as those of the second embodiment shown in FIG.

Next, referring to FIG. 4, a decorative pattern forming mold according to a fourth embodiment of the present invention will be described. FIG. 4 is a plan view showing a unit block 10 of a concrete formwork for decorative pattern formation according to the fourth embodiment.

This embodiment is basically the same as the second embodiment of FIG. 2, but the unit blocks 10, 10-1, 10-2, 10-3 are the same as those of FIG. It is vertically symmetrical with respect to the centerline extending in the lateral direction. Further, in the upper unit blocks 10 and 10-2, the partition line bc is on the right side, whereas in the lower unit blocks 10-1 and 10-3, the partition line bc is on the left side. There is.

In this structure, the upper dividing line ae of the unit block 10 is formed in almost the same curve as the lower dividing line cf , as in the second embodiment of FIG. At the same time, the upper demarcation line eb is formed in almost the same curve as the lower demarcation line fd . As a result, the upper unit blocks 10 ... Are shifted with respect to the lower unit blocks 10-1. In addition to this, the upper parting line ae + eb and the lower parting line cf + fd are formed to be vertically symmetrical.

Therefore, as described above, the orientation of the unit block can be reversed between the upper stage and the lower stage, and the upper unit blocks 10 and 10-2 and the lower stage blocks 10-1 and 10-3 are It can be arranged vertically symmetrically. Therefore, even if one type of unit block is reversed, the roles of two types of unit blocks can be played, and natural stones can be piled up by arranging a smaller number of unit blocks at random. A vibrant atmosphere can be created, and work on the site can be further reduced.

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 concrete pattern forming decorative pattern frame thus configured 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 placed between the unit block 10 and the concrete placing form 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 dividing line of the unit block is formed by the curved line, the seam can be made inconspicuous as compared with the case where the seam is a straight line. Further, since the shape of the entire unit block is also defined by the curved line, the degree of freedom in arranging stones is large, and the stones formed can be made larger than when the unit block is a quadrangle. In addition, the corners of the formed stone can be made into a gentle curve without making it sharp, and the shape can be made closer to a natural stone.

Since the division line of the unit block is a curve, there is no atmosphere in which stones are regularly piled up, and the formed masonry pattern is not a monotonous repetitive pattern, but an atmosphere in which random stones are piled up can be created. it can. Furthermore, since the dividing line (that is, the outer edge) of the unit block is a curve, it is possible to create an atmosphere in which natural stones are piled up by avoiding repeated patterns by simply arranging a few types of unit blocks at random. .. Therefore, the workers on the site only need to arrange the unit blocks randomly, which can reduce the work on the site.

Further, in the second invention, the seams between the unit blocks are shifted as compared with the first invention, so that the seams can be made more inconspicuous. Furthermore, since the unit blocks are arranged in a more random manner, it is possible to create an atmosphere in which natural stones are adjacent to each other, and to create a random pattern of stacked natural stones.
