Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an uneven pattern forming method for forming an uneven pattern on the surface of a concrete structure.

[Conventional technology]

Generally, in order to form an uneven pattern on the surface of a concrete structure, a shape material is used, in which an uneven pattern forming material made of resin or the like is adhered to one side of a substrate made of plywood or the like. Then, formwork etc. are assembled to this mold material to form a space, paste concrete is poured into the space, and after the concrete has hardened, the above mold material etc. are removed to create concrete with an uneven pattern on the surface. forming layers.

[Problem that the invention seeks to solve]

The above-mentioned uneven pattern is not only formed uniformly over the entire surface of the concrete layer, but also formed only on a part of the surface of the concrete layer, or with a pattern that is different from the rest of the part. It may be provided. As a mold material for forming such an uneven pattern and a forming method using the same,
There is one disclosed in Japanese Patent Publication No. 62-9439. In other words, this construction method involves cutting out a predetermined portion from a flat board, forming an uneven pattern on the surface of the cutout, and then inserting and fixing the cutout with the uneven pattern into the cutout hole of the board. A mold material is constructed, and the uneven pattern formed on the surface of the cutout portion is transferred onto the surface of a concrete layer using this mold material. However, with this construction method,
An uneven pattern is formed only on the surface of the concrete layer corresponding to the cut-out portion of the mold, and no pattern is formed on the surface of the concrete layer corresponding to other parts of the mold. Another problem is that manufacturing the mold material is troublesome because a part is cut out from a flat substrate and a pattern is applied to the surface of the cut-out part by engraving or the like.

The present invention was made in view of the above circumstances, and an object thereof is to provide a method for forming a concave-convex pattern, which facilitates the production of a molded material, and allows continuous formation of different patterns.

[Means for solving problems]

In order to achieve the above object, the uneven pattern forming method of the present invention involves stacking a patterned substrate having an uneven pattern on its upper surface on top of a flat substrate whose upper surface is flat or substantially flat with an uneven pattern. The stacked two-layer body is cut into a desired pattern shape and divided into a plurality of parts, and in each of the divided parts, the upper layer substrate or the lower layer is One of the substrates is removed so that a patterned substrate portion and a flat substrate portion remain, and the remaining portions are laterally spliced to form a single-layer shape material, and this shape material and a formwork etc. are used to create a space. A concrete structure with an uneven pattern on the surface is formed by forming a concrete structure, pouring paste concrete into this space, and removing the mold material and formwork after the concrete has hardened.

[Effect]

That is, in this uneven pattern forming method, a patterned substrate is stacked on a flat substrate whose upper surface is formed with a flat or uneven pattern, and in this state, both substrates are simultaneously cut into a plurality of parts so as to form a desired pattern shape. At the cutting part, adjacent flat plate substrate parts and patterned substrate parts are rearranged and assembled in a predetermined number in a horizontal joint to form a shape material. Therefore, by assembling a formwork etc. to this mold material to form a space for concrete formation, and pouring paste concrete into this space, the surface of the resulting concrete structure is coated with the flat surface of the flat substrate or The uneven pattern and the uneven pattern of the patterned substrate can be formed continuously. In addition, the pattern shape is expressed in a way that it stands out due to the boundary line created by the recombination of the cut flat substrate and patterned substrate. Furthermore, the manufacturing of the mold material involves stacking a patterned substrate with an uneven upper surface on the upper surface of a substantially planar flat substrate whose upper surface has been formed with a flat or uneven pattern, and then cutting the patterned substrate. It is easy to assemble the part and the part of the patterned board in a horizontal joint as appropriate.

Next, the present invention will be explained in detail based on examples.
